Fig. 3 has described the application of method in compatible 802.16e and 802.16m wireless communication system that utilizes the present invention to propose.The base station is divided into several set of terminal according to certain dividing mode with a plurality of terminals and the terminal in the group is sorted, terminal in each group all is the 802.16m terminal, and know that all the group number at own place and base station are own serial number information in group, the base station is divided into 802.16e zone and 802.16m zone two parts with descending sub frame, as shown in Figure 3, concrete steps are as follows:
Step 301: the base station is written in the 802.16m zone after with the control information of terminal coding, generates an independently indication information of terminal control information region, has comprised the information of control information in the above-mentioned zone that whether needs to decode in this indication information;
Step 302: the base station writes indication information in the one's respective area, and by DL-MAP message control information and indication information is sent to terminal;
Step 303: after the 802.16m terminal in the group is received this message it is decoded, determine whether control information in the needs decode successive 802.16m zone according to the information that decodes.
In the described step 301, indication information comprises message number and several elements, each element inclusion region sign, the corresponding bit sequence BITMAP of terminal during group number reaches and organizes, the terminal that the value of each the bit position in this bit sequence is used for indication group relevant position whether need be in this element decoding control information in the zone of area identification correspondence, as the terminal of correspondence position in the bit value is represented to organize when " 1 " need be in this element decoding control information in the zone of area identification correspondence, in representing to organize during for " 0 " terminal of correspondence position need be in this element decoding control information in the zone of area identification correspondence.
In the described step 303, during the element of this message of 802.16m decoding terminals in the group, if find to contain in certain element the group number of own place group, then this terminal need be analyzed bit situation corresponding with own position among the bit sequence BITMAP, if bit is " 1 ", then this terminal is known the control information that oneself needs in the decode successive 802.16m zone; If bit is " 0 ", then this terminal is known the control information that oneself does not need in the decode successive 802.16m zone.
Notion below by the further middle bit sequence BITMAP of an example, if comprise ten terminals in the group, and the serial number information of each terminal in group is known to terminal, bit sequence BITMAP comprises ten bit in this case, wherein the value of first bit be used for indicating corresponding group sequence number be 1 terminal whether need be in this element decoding control information in the zone of area identification correspondence, second bit be used for indication group sequence number be 2 terminal whether need be in this element decoding control information in the zone of area identification correspondence, by that analogy, if first bit is " 1 " among the bit sequence BITMAP, sequence number is need decode the control information in the appointed area of 1 terminal in the then expression group, if first bit is " 0 " among the bit sequence BITMAP, sequence number is do not need to decode the control information in the appointed area of 1 terminal in the then expression group.
Required bit number below by an example further middle the present invention can the reduction effectively indication information by the notion of introducing group.If do not introduce the notion of group, describe a terminal usually and need use 16 bit, if there are 9 terminals to need control information in the decode successive zone like this, describing these 9 terminals just needs 16 * 9=144 bit.During if the notion of employing group is come, suppose to comprise in the group 20 terminals, wherein there are 9 terminals to need control information in the decode successive zone, generally need 4 (bit number that group number is required)+20=24 bits when then adopting these 9 terminals of message semantic definition of tape identification position not, this terminal of message semantic definition that adopts the tape identification position is generally to need 4 (bit number that group number is required)+1+20=25 bits.Further comprise 9 terminals in the hypothesis group, wherein each terminal all needs the control information in the decode successive zone, need 4 (bit number that group number is required)+9=13 bits when then adopting the message semantic definition of tape identification position not, need 4 (bit number that group number is required)+1=5 bits when adopting the message semantic definition of tape identification position.
