Below in conjunction with accompanying drawing, to provided by the invention a kind of descending/the generation method of uplink frame channel allocation DL/UL MAP message and the execution mode of device be described.
Embodiments provide a kind of generation method of descending/upper hand-manipulating of needle channel allocation DL/UL MAP message, this DL/UL MAP message adopts the mode combined with Sub-map message and Compressed map message, comprising:
According to the modulation coding mode belonged to indicated by all uplink frame channel assignment message information unit UL MAPIE of assignment information unit IE and downlink frame channel assignment message information unit DL MAP IE, the UL MAP IE of the identical modulation system of instruction and DL MAP IE is set up into corresponding son descending/uplink frame channel allocation Sub-map message;
The all UL MAP IE belonging to control IE and DL MAP IE are set up into compression descending/uplink frame channel allocation Compressed map message.
Below, to the flow process detailed description generating Sub-map message and Compressed map message.
In embodiments of the present invention, before generating Sub-map message and Compressed map message, need first to uplink frame channel assignment message information unit (the Uplink Map Information Element generated, UL MAP IE) process, and the downlink frame channel assignment message information unit (DownlinkMap Information Element, DL MAP IE) generated is processed.
First the process generating and process UL MAP IE is described.
When dispatching up connection, network side distributes bandwidth according to different dispatching algorithms to travelling carriage (MobileStation, MS), determines the division of sub-frame of uplink, and preserves the result of scheduling; Each uplink frame channel assignment message information unit (Uplink Map Information Element, UL MAP IE) is generated according to scheduling result.This process belongs to prior art, no longer describes in detail in the embodiment of the present invention.
As shown in Figure 1, the step that the UL MAP IE generated is further processed is comprised:
The UL MAP IE that step 101, judgement generate belongs to control IE or distributes IE.If control IE, perform step 102, otherwise, perform step 103.
Step 102, the UL MAP IE that will belong to control IE write in compression uplink frame channel allocation CompressUL MAP message.
The uplink interval that step 103, judgement belong in the UL MAP IE distributing IE uses code (UplinkInterval Usage Code, UIUC) whether the modulation coding mode of field instruction is quaternary phase shift keying (Quadrature Phase-Shift Keying, QPSK) 1/2 or QPSK3/4 mode, if, perform step 104, if not, perform step 105.
Step 104, a definition Map qPSKarray, this Map qPSKfor depositing the UL MAP IE that the modulation coding mode of its UIUC field instruction is QPSK1/2 or QPSK3/4, the UL MAP IE being QPSK1/2 or QPSK3/4 by instruction modulation coding mode writes this Map qPSKarray.
Whether the modulation coding mode of the UIUC field instruction that step 105, judgement belong in the UL MAP IE distributing IE is 16QAM1/2 or 16QAM3/4, if so, then performs step 106, otherwise performs step 107;
Step 106, a definition Map 16QAMarray, this Map 16QAMarray is 16 quadrature amplitude adjustment (Quadrature Amplitude Modulation for depositing the modulation coding mode of UIUC field instruction, QAM) 1/2 or the UL MAP IE of 16QAM 3/4, the UL MAP IE being 16QAM 1/2 or 16QAM 3/4 by instruction modulation coding mode writes this Map 16QAMarray.
Step 107, a definition Map 64QAMarray, the UL MAP IE being 64QAM1/2,64QAM2/3,64QAM3/4 or 64QAM5/6 by the modulation coding mode that its UIUC field indicates is written to this Map 64QAMin array.
Because the modulation coding mode indicated by UIUC field of UL MAP IE is except QPSK1/2, QPSK3/4,16QAM 1/2 or 16QAM 3/4, remaining should be exactly one of this several mode of 64QAM1/2,64QAM2/3,64QAM3/4 or 64QAM5/6, therefore, in this step 107, the UL MAP IE directly indicated modulation system can not being belonged to QPSK and 16QAM writes Map 64QAMin array.
Step 108, judge that whether all UL MAP IE (no matter being control IE or distribution IE) are all processed and complete, the flow process of the UL MAP IE that if so, ends process, if not, jumps to step 101.
Network side is dispatched to all descending connections, distributes bandwidth, determine the division of descending sub frame according to different dispatching algorithms, and preserves the result of scheduling; According to the scheduling result to descending connection, generate each downlink frame channel assignment message information unit (Downlink Map Information Element, DL MAP IE).
As shown in Figure 2, the step that the DL MAP IE generated is further processed is comprised:
The DL MAP IE that step 201, judgement generate belongs to control IE or distributes IE.If control IE, perform step 202, otherwise, perform step 203.
Step 202, the DL MAP IE that will belong to control IE write in compression downlink frame channel allocation Compressed DL MAP message.
The downlink interval that step 203, judgement belong in the DL MAP IE distributing IE uses code (DownlinkInterval Usage Code, DIUC) whether the modulation coding mode of field instruction is QPSK1/2 or QPSK3/4 mode, if, perform step 204, if not, perform step 205.
Step 204, a definition Sub-map message array Smap qPSK, the DL MAP IE being QPSK1/2 or QPSK3/4 by the modulation coding mode that DIUC field indicates writes this Smap qPSKin array.
Due to this Smap qPSKarray finally can generate the Sub-map message that corresponding modulation coding mode is QPSK1/2, therefore, when write DL MAP IE, needs the header fields reserving this Sub-map message to write in the process of this Sub-map message of follow-up generation again.
Whether the modulation coding mode of the DIUC field instruction that step 205, judgement belong in the DL MAP IE distributing IE is 16QAM1/2 or 16QAM3/4, if so, then performs step 206, otherwise, perform step 207;
Step 206, a definition Sub-map message array Smap 16QAM, the DL MAP IE being 16QAM1/2 or 16QAM3/4 by the modulation coding mode that DIUC field indicates writes this Smap 16QAMin array.
Due to this Smap qPSKarray finally can generate the Sub-map message that corresponding modulation coding mode is 16QAM1/2, therefore, when write DL MAP IE, needs the header fields reserving this Sub-map message to write in the process of this Sub-map message of follow-up generation again.
Step 207, a definition Sub-map message array Smap 64QAM, the ULMAP IE being 64QAM1/2,64QAM2/3,64QAM3/4 or 64QAM5/6 by the modulation coding mode that its DIUC field indicates is written to this Smap 64QAMin array.
Due to this Smap 64QAMarray finally can generate the Sub-map message that corresponding modulation coding mode is 64QAM1/2, therefore, when write DL MAP IE, needs the header fields reserving this Sub-map message to write in the process of this Sub-map message of follow-up generation again.
Step 208, judge that whether all DL MAP IE (no matter be control IE or distribute IE) is all processed and complete, the flow process of the DL MAP IE that if so, ends process, if not, jumps to step 201.
Below in order to distinguish, by the Map that flow process as shown in Figure 1 generates qPSK, Map 16QAMand Map 64QAMarray is called first kind Sub-map message array; By the Smap that flow process as shown in Figure 2 generates qPSK, Smap 16QAMand Smap 64QAMbe called Equations of The Second Kind Sub-map message array.
Generate the flow process of Sub-map message and Compressed map message, as shown in Figure 3, comprise the steps:
Step 301, judge first kind Sub-map message array (i.e. Map qPSK, Map 16QAMand Map 64QAMarray) in whether have data to exist, if all there is no data in first kind Sub-map message array, then turn to perform step S304, otherwise, perform step S302;
Step 302, by Map qPSK, Map 16QAMand Map 64QAMuL MAP IE in array is written to the identical Equations of The Second Kind Sub-map message array of modulation system, and (that corresponding is Smap respectively qPSK, Smap 16QAMand Smap 64QAM) in after DL MAP IE, and add corresponding message header field, generate corresponding Sub-map message.
For example, by Map qPSKall UL MAP IE in array are written to Smap qPSKin array after all DL MAP IE, like this, and before all DL MAP IE, add the message header field of this Sub-map message, final generation modulation coding mode is the Sub-map message of QPSK1/2.
Due to Smap qPSK, Smap 16QAMand Smap 64QAMarray, Map qPSK, Map 16QAMand Map 64QAMin array, each array all may there be data, or only have part array to have data, therefore can generate the Sub-map message that quantity is not more than 3.If there are 3 Sub-map message generations, so the modulation system of these 3 Sub-map message is respectively QPSK1/2,16QAM1/2 and 64QAM1/2.
The total length of each Sub-map message generated equals the length sum of the length of length, wherein the DL MAP IE of fixed field and the UL MAP IE of step 303 write.
Step 303, the Sub-map message generated according to step 302, add corresponding Sub-map message instruction IE in Compressed DL MAP message.And, if the Sub-map message generated is dispensed among different Zone, and not be dispensed in the middle of default Zone, so before the Sub-map message instruction IE that this Sub-map message is corresponding, also need to add Zone and there is the Zone that instruction IE, Zone existence instruction IE is used to indicate the non-default that this Sub-map message is assigned with.
The corresponding Sub-map message of each Sub-map message instruction IE, if generate 3 Sub-map message in step 303, the instruction of Sub-map message IE, the Sub-map message instruction IE that then interpolation 3 is corresponding in Compressed DL MAP message such as can use existing mixing repeat requests and Sub-MAP message instruction IE (HARQ and Sub-MAP Pointer IE).
Zone exists instruction IE can adopt such as existing STC Zone IE.Each Sub-map message can be dispensed in same Zone, also can be dispensed in different Zone respectively.
Step 304, judge whether Compressed UL MAP message exists, exist, then perform step step S305, otherwise flow process terminates, Compressed DL MAP message and Compressed MAP message.
Step 305, Compressed UL MAP message is attached to Compressed DL MAP message after, set up into Compressed map message.
In this step 305, the length of the Compressed map message of generation equals Compressed ULMAP message and Compressed DL MAP message length sum.
After setting up into Compressed map message, flow process terminates.
