Fig. 2 has described concrete use of method in the data transmission system that adopts OFDM (Orthogonal FrequencyDivision Multiplexing) technology that the present invention proposes, supposing the system is assigned to terminal in the different groups according to certain criterion, every group identifies by a group number, terminal in the group is known own relative position in group, and the base station has been that the downlink resource of each set of dispense fixed position and size (is supposed to be made up of n descending basic resource blocks, its call number is 1, n), step is as follows:

Step 201, the base station is the terminal distribution downlink resource in the group that needs the transmission downlink data, sends this message by the terminal of downstream message mode in group, this message comprises group number, information field, resource allocation information bit sequence at least;

Wherein, group number is represented the group of this resource allocation message correspondence.

Information field can show as the form of terminal number+BITMAP sequence, wherein what terminals are the terminal number represent to have in the group to adjust the follow-up work mode according to this control messages, comprise several bits in the BITMAP sequence, after receiving this control messages, the corresponding with it terminal of bit ' 0 ' expression do not need to adjust the follow-up work mode, after receiving this control messages, the corresponding with it terminal of bit ' 1 ' expression needs to adjust the follow-up work mode, relative position is 1 terminal in the corresponding group of first bit in the BITMAP sequence, relative position was 2 terminal during second bit correspondence organized, the BITMAP sequence is ended during the terminal number described before BITMAP sequence intermediate value equals for ' 1 ' bit number by that analogy.

The terminal that each bit in the resource allocation information bit sequence need in this group to represent downlink data receiving is the number of the descending basic resource blocks that obtains the downlink resource of this set of dispense from the base station, the length of this bit sequence equals to need in the information field to receive from the base station terminal number of data, the terminal of wherein describing in first bit corresponding informance territory that needs downlink data receiving of relative position minimum in group, the terminal that needs downlink data receiving that the relative position in group described in second bit corresponding informance territory second is little, by that analogy, suppose that bit value needs 2 descending basic resource blocks for ' 1 ' expression counterpart terminal, bit value is that ' 0 ' expression counterpart terminal needs 1 descending basic resource blocks.But, also be not limited to the only corresponding bit of each terminal in the resource allocation field, also can adopt other indicating modes, for example a terminal is corresponding a plurality of than top grade, as long as base station and terminal consult.

Step 202, after terminal receives the control messages of expression downlink resource distribution in the group, determine according to information field whether oneself has been assigned with downlink resource, the terminal that has been assigned with downlink resource determines to distribute to resource location and the resource size of oneself according to described resource allocation information bit sequence.

After terminal in the group receives that information field is expressed as the control messages based on group of terminal number+BITMAP sequence, if what terminals are the negotiation terminal number be expressed as need be according to the resource allocation information downlink data receiving of this control messages description the time before terminal and the base station, subsequent bits intermediate value behind the terminal statistics terminal digital section is ' 1 ' number, when the number when ' 1 ' equals the terminal number, terminal with this section bit sequence as the BITMAP sequence, if terminal can find the bit information of own correspondence position in this BITMAP sequence, when being ' 1 ', this value represents that this terminal need be according to the control messages adjustment follow-up work mode that receives, represent that this terminal can ignore this information for ' 0 ' time, if terminal can not find the bit information of own correspondence position in this BITMAP sequence, that is to say the length of the relative position value of terminal in group greater than the BITMAP sequence, this moment, terminal can be ignored this information.
