Embodiment
The present invention will describe with reference to the accompanying drawing of drawing, and wherein expression such as numeral runs through the element of full text.
According to the present invention, a kind of being used for distributed to time slot method 53 use continuation codes with sign indicating number, and will be described with reference to the flow chart of figure 3, said sign indicating number divided be used in simply being described in shown in Fig. 4 of UE A, UE B and UE C.In Fig. 4, show ten two (12) individual potential time slots and ten six (16) individual potential sign indicating numbers, but the present invention is not limited to the time slot and/or the sign indicating number of given number.
Each time slot can be assigned with to potentiality predetermined number object code, for example 16 sign indicating numbers.This predetermined number object code is assigned with an order or order, for example from 0 to 15, (step 54).For specific UE, only continuous sign indicating number is assigned to the UE in given time slot, (step 56).In order to describe, with reference to figure 4, UE A is dispensed on the sign indicating number 4-8 in the time slot 2. Sign indicating number 1,3 and 4 does not allow to be assigned to UE A, only if sign indicating number 2 also is assigned to UE A.Likewise, UE A has been assigned with a yard 6-9 in time slot 6; UE B in time slot 2, has been assigned with yard 9-12 and oneself is assigned with a yard 0-13 in time slot 9; And UE C has been assigned with a yard 1-5 in time slot 11.
Return with reference to figure 3,,, need first yard and the indication of last sign indicating number of continuation code for each distributed time slot for this allocative decision is sent to UE with signal, (step 58), for ten six (16) individual potential sign indicating number orders, need eight (8) individual bits.The number (sign indicating number 0 to 15) of four (4) individual bit indication initial codes (sign indicating number 0 to 15) and four (4) last sign indicating numbers of individual bit indication or continuation code, or the number of continuation code (1 to 16).For the system of ten two (12) time slots, need 96 bits, (every time slot eight (8) individual bits multiply by ten two (12) individual time slots).
The method of the bit number in a kind of downlink transmission that is used for reducing control channel is only to send the fraction of assignment information with signal through control channel; (hereinafter referred to as " information of sending with signal earlier "); And send the remainder of assignment information with down link data; (hereinafter referred to as " information that send with signal the back "); To experience the AM&C processing identical with the back information of sending that down link data sends together, and therefore reduce significantly and transmitted the required air resource of assignment information through control channel with said data with signal.
In exemplary systems, spend two (2) time slots with restore data, this is because this control information must be received and be processed then to prepare to receive actual data.To be used to transmit down link data, this elder generation comprises the designator of four (4) bits of the time slot that is used for first use to the essential therefore relaying of information that this elder generation sends with signal with the information of signal transmission for the assignment information of the first two (2) individual time slot; The designator that is used for four (4) bits of next time slot; And be used for the time slot that uses each first with the designator of last sign indicating number, (each time slot two (2) bit).Thereby having only is at most that ten six (16) bits are used to send the information of sending with signal earlier with signal.Remaining assignment information is to be sent out together with the information of same down link data that signal sends as the back.As a result, for ten six (16) yards and slot sytem ten two (12) time, having only ten six (16) bits is the information of sending with signal earlier, and the residue back is sent with signal with down link data with the signal information of sending.
An advantage of this method is its use that allows any several object codes in the when crack in office.Yet this method need be used for typically at least two time slot allocation, and the signaling of distribution that maybe all time slots.Though this has limited for the sign indicating number of continuation code and has selected, with the use of sign indicating number reallocation, this restriction is not remarkable.If best reallocation needs discontinuous sign indicating number, then the use of this time slot UE sign indicating number can be encapsulated only to allow continuation code to distribute to all UE again.
The second method 80 that is used for assigned code and time slot is used common continuation code, and reference flow sheet Fig. 5, and the simple declaration to the distribution of UE A, UE B and UE C sign indicating number is described in Fig. 6.Each time slot is distributed the predetermined number object code potentially, for example ten six (16) individual sign indicating numbers.The predetermined number of sign indicating number is assigned with an order or order, for example from 0 to 15, (step 82).The phase continuation code on the same group of distributing to a time slot must be assigned to all time slots that are used for particular UE, (step 84).In order to use Fig. 6 to describe, UE A assigned slot 2,3 and 11, and in each time slot, be assigned with a yard 2-4.Yet because UE A has been assigned with sign indicating number 2-4 in time slot 2, it can not only be assigned with sign indicating number 2 or sign indicating number 2-5 in other time slot.Likewise, UE B is assigned with a yard 0-13 in time slot 8 and 9; And UE C is assigned with sign indicating number 11 in time slot 11 and 12.
Give UE in order to send this allocative decision, need this first and the indication of last sign indicating number and designator (step 86) of employed time slot of group continuously with signal.For the system of Fig. 6, for continuation code, need eight (8) bits, (four (4) bits be used for first yard with four (4) bits be used for last sign indicating number or yard number), and ten two (12) bits are used to identify the time slot of use).Each bit is corresponding to a time slot.Plant in the execution mode one (1), this time slot of one (1) bit value indication is used, and zero (0) bit value indicates it not to be used.Therefore need 20 (20) individual bits altogether.
Reduced the number of elder generation with signal transmission information and back with the use that signal sends information and method 80 earlier with signal transmission bit.This elder generation must indicate first and last sign indicating number of the first use time slot and back to back time slot and public order with the signal information of sending.For the system of Fig. 6, the first two (2) time slot of this ten two (12) time slot of eight (8) bits indication (each time slot of four (4) bits indication), and eight (8) bits are used for the number of this starting and ending sign indicating number or sign indicating number.So, need altogether ten six (16) bits of elder generation with the information of signal transmission.
In order to reduce the bit of this elder generation with the information of signal transmission further, five (5) bits can be used to the first two (2) individual time slot.The time slot of this first use of four (4) bits indication, and the 15 bit representes whether time slot then is used.As a result, ten six (16) or ten three (13) bits are the information of sending with signal earlier, and the information of then using signal to send is maximum ten (10) bits.
An advantage of second method is that it has reduced the number of elder generation with the information of signal transmission.A shortcoming is its flexibility that has reduced sign indicating number and time slot allocation, and this is because each time slot that particular UE is used all must be assigned with identical sign indicating number.
The third method 90 that is used for sign indicating number and time slot allocation is used the common continuation code of continuous slot, and reference flow sheet Fig. 7, and is described for this yard simple declaration that is distributed among Fig. 8 of UE A, UE B and UE C.Each time slot is distributed the predetermined number object code potentially, for example ten six (16) yards.This predetermined number object code is assigned with an order or order, for example from 0 to 15, (step 92).In this method, not only same code is assigned to each employed time slot, and has only continuous time slot can be assigned with (step 94).In order to use Fig. 8 to describe, UE A is dispensed on the sign indicating number 2-4 among the time slot 5-7.Yet UE A can not be dispensed on the sign indicating number 2-4 in time slot 5,6 and 8, only if time slot 7 also is assigned with.Likewise, UE B is dispensed on the sign indicating number 0-13 in time slot 8 and 9.UEB can not be dispensed in any other time slot still less or the sign indicating number of greater number, can not be dispensed in time slot 11 or 12 the sign indicating number 0-13, only if time slot 10 is assigned with.UE C is dispensed on the sign indicating number 11 in the time slot 11.
Give UE in order to send this allocative decision with signal, first of the assigned code in each distributed time slot is sent (step 96) with the indication (or number) of first and last time slot of the indication (or number) of last assigned code and distributed time slot with signal.For the system of Fig. 8, need eight (8) bits be used for the distribution of sign indicating number and the distribution that eight (8) bits are used for time slot, (four (4) individual first time slots and four (4) that are used for individually are used for last time slot, or the number of time slot), ten six (16) individual bits altogether.
Information with the signal transmission has reduced the number of elder generation with the bit of signal transmission with the back with the information of signal transmission and the use of the method 90 earlier.In the method 90, ten three (13) bits must be sent with signal earlier before the data, (eight (8) individually are used for the sign indicating number that time slot uses, and four (4) individually are used for first and use time slot, and whether one (1) bit indicates other time slot to be used).If other time slot is used, then indicates four (4) bits of the number of last time slot or time slot to be used as the information and date one that sends with signal the back and reinstate signal and send.
This third method has limited the quantity of signaling, but is cost with the flexibility of the distribution of sign indicating number/time slot.
The 4th kind of method 100 that is used for assigned code and time slot distributed to UE with all sign indicating numbers of time slot, and reference flow sheet Fig. 9 and in Figure 10 the simple declaration for this distribution of UE A, UE B and UE C be described.In the method, the sign indicating numbers of all in the said UE assigned slot (step 102).Use Figure 10 describes, and UE A is assigned with the sign indicating number of all time slots 2 and 5, UE B assigned slot 8 and 9 all the sign indicating number, and UE C assigned slot 11 all the sign indicating number.
In order to send this allocative decision to UE with signal, the designator of time slot that needs distribute, (step 104).For the system of Figure 10, this designator is ten two (12) bit fields, has each bit and representes whether a specific time slot is used.Typically, UE knows the maximum number of sign indicating number in the time slot.Yet if do not know the maximum number of sign indicating number, the designator of the number of sign indicating number is sent out, (also being the part of step 104), and for example four (4) bits indication maximum quantity is the sign indicating number of scope from 0 to 16.
Information with the signal transmission has reduced the number of elder generation with the bit of signal transmission with the back with the information of signal transmission and the use of the method 100 earlier.In the method 100, the designator of this first two time slot that uses is sent with signal.For the system of Figure 10, these two time slot designators are eight (8) bits.Residue distributes the designator of time slot to be sent with signal with the data of information in first time slot that signal sends as the back.Replacedly, in order further to reduce the number of the bit that sends, can use five (5) bits of elder generation with the information of signal transmission.Whether four (4) bits this first time slot of indication and the 5th bit indicate ensuing time slot to be used.
The 5th kind of method 110 used complete continuous slot for sign indicating number and time slot allocation, and reference flow sheet Figure 11 and in Figure 12 the simple declaration for this distribution of this UE A, UE B and UE C describe.In the method, UE is assigned with all sign indicating numbers (step 112) in the continuous time slot.In order to use Figure 12 to describe, all sign indicating numbers of UE A assigned slot 2-4.Do not distributing for UE A under the situation of time slot 4, UE A can not assigned slot 2,3 and all sign indicating numbers of 5.Likewise, UE B assigned slot 8 and all sign indicating numbers of 9; And all sign indicating numbers of UE C assigned slot 11.
Give UE in order to send this allocative decision with signal, the designator (or number) of first and last time slot of the time slot of use is sent (step 114) with signal.For the system of Figure 11, need eight (8) bits, (four (4) individual time slot and four (4) the individual last time slot or the numbers of time slot of being used for that are used for first use).
Information with the signal transmission has reduced the number of elder generation with the bit of signal transmission with the back with the information of signal transmission and the use of the method 110 earlier.In the method 110, only five (5) individual bits are as being sent out with the information of signal transmission earlier.Whether sign indicating number that four (4) individual bit indications first are used and the 5th bit indication time slot then are used (step 74).If should be used by time slot then, then four (4) the bits information of sending with signal as the back is sent to indicate the last time slot or the number of time slot with signal with the down link data of transmission.
All sign indicating numbers in 120 pairs of all time slots of the 6th kind of method are numbering continuously, and is described with reference to the simple declaration that distributes for this sign indicating number of UEA, UE B and UE C among the flow chart of Figure 14 and Figure 15.In the method 120, all sign indicating numbers in all time slots are numbered (step 122) continuously, and this UE is assigned with then needs number object code (step 124).In order to use Figure 15 to describe, UE A is assigned with a yard 69-99, and UE B is assigned with yard 129-142 and UE C is assigned with a yard 162-181.
For this allocative decision is sent to UE with signal, need this first with the indication (step 126) of last sign indicating number.For the system of Figure 15, this designator is ten six (16) bits, (eight (8) bits are used for this first yard and eight (8) bits and are used for last sign indicating number).Replacedly, this designator of first yard can be sent with signal with the number of sign indicating number; Especially hour at the number of this yard.
The information that send with signal the information of sending with signal earlier and back and the use of the method 120 have reduced before the number with the bit of signal transmission; In the method 120; Ten three (13) bits must be sent with signal as the information of sending with signal earlier, (eight (8) bits be used for first yard and five (5) bits are used for the number of the sign indicating number of the first two (2) time slot).If more yards are used, then the counting of sign indicating number can be replaced in the information that send with signal the back.
Summarize in the table of Figure 13 with signal and send the required bit of sign indicating number/time slot allocation for six (6) kind schemes of ten six (16) yards and ten two (12) slot sytems when available.
