The embodiment of the invention provide a kind of descending/go up the generation method of hand-manipulating of needle channel allocation DL/UL MAP message, this DL/UL MAP message adopts the mode that combines with Sub-map message and Compressed map message, comprising:
According to all uplink frame channel assignment message information unit UL MAPIE that belong to assignment information unit IE and the indicated modulation coding mode of downlink frame channel assignment message information unit DL MAP IE, the UL MAP IE of the identical modulation system of indication is set up corresponding sub descending/uplink frame channel allocation Sub-map message with DL MAP IE;
To belong to all UL MAP IE of controlling IE and DL MAP IE set up into compression descending/uplink frame channel allocation Compressed map message.
Below, to generating the detailed explanation of flow process of Sub-map message and Compressed map message.
In embodiments of the present invention, generate before Sub-map message and the Compressed map message, need uplink frame channel assignment message information unit (the Uplink Map Information Element to generating earlier, UL MAP IE) handles, and the downlink frame channel assignment message information unit (DownlinkMap Information Element, DL MAP IE) that generates handled.
At first explanation generates and handles the process of UL MAP IE.
When up connection was dispatched, network side is given travelling carriage according to different dispatching algorithms, and (MobileStation MS) distributed bandwidth, determines the division of sub-frame of uplink, and preserves the result of scheduling; Generate each uplink frame channel assignment message information unit (Uplink Map Information Element, UL MAP IE) according to scheduling result.This process belongs to prior art, no longer describes in detail in the embodiment of the invention.
As shown in Figure 1, the step that the UL MAP IE that generates is handled further comprises:
The UL MAP IE that step 101, judgement generate belongs to control IE or distributes IE.If control IE, execution in step 102, otherwise, execution in step 103.
Step 102, will belong to the UL MAP IE that controls IE and write in the compression uplink frame channel allocation CompressUL MAP message.
The uplink interval that step 103, judgement belong among the UL MAP IE that distributes IE uses a sign indicating number (UplinkInterval Usage Code, UIUC) whether the modulation coding mode of field indication is quaternary phase shift keying (Quadrature Phase-Shift Keying, QPSK) 1/2 or the QPSK3/4 mode, if, execution in step 104, if not, execution in step 105.
Step 104, Map of definition
QPSKArray, this Map
QPSKThe modulation coding mode that is used to deposit its UIUC field indication is the UL MAP IE of QPSK1/2 or QPSK3/4, is that the UL MAP IE of QPSK1/2 or QPSK3/4 writes this Map with the indication modulation coding mode
QPSKArray.
Whether the modulation coding mode that step 105, judgement belong to the UIUC field indication among the UL MAP IE that distributes IE is 16QAM1/2 or 16QAM3/4, if then execution in step 106, otherwise execution in step 107;
Step 106, Map of definition
16QAMArray, this Map
16QAMThe modulation coding mode that array is used to deposit the indication of UIUC field is 16 quadrature amplitude adjustment (Quadrature Amplitude Modulation, QAM) 1/2 or the UL MAP IE of 16QAM 3/4, be that the UL MAP IE of 16QAM 1/2 or 16QAM 3/4 writes this Map with the indication modulation coding mode
16QAMArray.
Step 107, Map of definition
64QAMArray is that the UL MAP IE of 64QAM1/2,64QAM2/3,64QAM3/4 or 64QAM5/6 is written to this Map with the modulation coding mode of its UIUC field indication
64QAMIn the array.
Because the indicated modulation coding mode of the 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 64QAM1/2,64QAM2/3,64QAM3/4 or these several modes of 64QAM5/6, therefore, in this step 107, the UL MAP IE that can directly indicated modulation system not belonged to QPSK and 16QAM writes Map
64QAMIn the array.
Step 108 judges whether all UL MAP IE (no matter being control IE or distribution IE) all finish dealing with, if the flow process of end process UL MAP IE if not, jumps to step 101.
Network side distributes bandwidth to all descending connections are dispatched according to different dispatching algorithms, determines the division of descending sub frame, and preserves the result of scheduling; According to scheduling result, generate each downlink frame channel assignment message information unit (Downlink Map Information Element, DL MAP IE) to descending connection.
As shown in Figure 2, the step that the DL MAP IE that generates is handled further comprises:
The DL MAP IE that step 201, judgement generate belongs to control IE or distributes IE.If control IE, execution in step 202, otherwise, execution in step 203.
Step 202, will belong to the DL MAP IE that controls IE and write in the compression downlink frame channel allocation Compressed DL MAP message.
The downlink interval that step 203, judgement belong among the DL MAP IE that distributes IE is used a sign indicating number (DownlinkInterval Usage Code, DIUC) whether the modulation coding mode of field indication is QPSK1/2 or QPSK3/4 mode, if, execution in step 204, if not, execution in step 205.
Step 204, Sub-map message array Smap of definition
QPSK, be that the DL MAP IE of QPSK1/2 or QPSK3/4 writes this Smap with the modulation coding mode of DIUC field indication
QPSKIn the array.
Because this Smap
QPSKIt is the Sub-map message of QPSK1/2 that array finally can generate corresponding modulation coding mode, therefore, when writing DL MAP IE, need reserve the header fields of this Sub-map message so that write in the process of this Sub-map message of follow-up generation again.
Whether the modulation coding mode that step 205, judgement belong to the DIUC field indication among the DL MAP IE that distributes IE is 16QAM1/2 or 16QAM3/4, if then execution in step 206, otherwise, execution in step 207;
Step 206, Sub-map message array Smap of definition
16QAM, be that the DL MAP IE of 16QAM1/2 or 16QAM3/4 writes this Smap with the modulation coding mode of DIUC field indication
16QAMIn the array.
Because this Smap
QPSKIt is the Sub-map message of 16QAM1/2 that array finally can generate corresponding modulation coding mode, therefore, when writing DL MAP IE, need reserve the header fields of this Sub-map message so that write in the process of this Sub-map message of follow-up generation again.
Step 207, Sub-map message array Smap of definition
64QAM, be that the ULMAP IE of 64QAM1/2,64QAM2/3,64QAM3/4 or 64QAM5/6 is written to this Smap with the modulation coding mode of its DIUC field indication
64QAMIn the array.
Because this Smap
64QAMIt is the Sub-map message of 64QAM1/2 that array finally can generate corresponding modulation coding mode, therefore, when writing DL MAP IE, need reserve the header fields of this Sub-map message so that write in the process of this Sub-map message of follow-up generation again.
Step 208, judge whether all DL MAP IE (no matter be control IE or distribute IE) all finish dealing with, if the flow process of end process DL MAP IE if not, jumps to step 201.
Below in order to distinguish, with the Map that flow process generated as shown in Figure 1
QPSK, Map

16QAMAnd Map
64QAMArray) whether there are data to exist in,, then turn to execution in step S304 if all do not have data in the first kind Sub-map message array, otherwise, execution in step S302;
Step 302, with Map

For instance, with Map
QPSKAll UL MAP IE in the array are written to Smap
QPSKAfter all DL MAP IE, like this, and before all DL MAP IE, add the message header field of this Sub-map message in the array, finally generating modulation coding mode is the Sub-map message of QPSK1/2.
Because Smap

16QAMAnd Smap
64QAMArray, Map
QPSK, Map
16QAMAnd Map
64QAMIn the array, possible each array all has data, perhaps has only the 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 to generate, the modulation system of these 3 Sub-map message is respectively QPSK1/2,16QAM1/2 and 64QAM1/2 so.
The total length of each the Sub-map message that generates equals the length of fixed field, the wherein length of DL MAP IE and the length sum of the UL MAP IE that step 303 writes.
Step 303, according to the Sub-map message that step 302 generates, in Compressed DL MAP message, add corresponding Sub-map message indication IE.And, if the Sub-map message that generates is dispensed among the different Zone, and not to be dispensed in the middle of the default Zone, so before the Sub-map message indication IE of this Sub-map message correspondence, also need to add Zone and have indication IE, Zone exists indication IE to be used to the non-default Zone that indicates this Sub-map message to be assigned with.
The corresponding Sub-map message of each Sub-map message indication IE, if generated 3 Sub-map message in the step 303, then add the Sub-map message indication IE of 3 correspondences in Compressed DL MAP message, Sub-map message indication IE for example can use existing mixing repeat requests and Sub-MAP message indication IE (HARQ and Sub-MAP Pointer IE).
Zone exists indication IE can adopt for example existing STC Zone IE.Each Sub-map message can be dispensed among the same Zone, also can be dispensed on respectively among the different Zone.
Step 304, judge whether Compressed UL MAP message exists, exist, execution in step step S305 then, otherwise flow process finishes, and Compressed DL MAP message is 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.
