specific Embodiment approach 1
[0028] Specific implementation mode one: as figure 1 As shown, this embodiment describes the TD-LTE public network cluster multimedia service uplink resource scheduling method:
[0029] Assume that in a cell network, the uplink bandwidth is divided into M RBs, and there is one base station and N active wireless users. The base station can allocate M RBs to the N users. In each transmission time interval, RBs satisfying multiple continuity constraints are allocated to the same user, but each RB can only be allocated to one user at most. We assume that the channel is in the case of Rayleigh fading, and the uplink transmission time interval is 1ms, which contains two 0.5ms time slots. Users of this system have different priorities and the system is dynamic, which is allocated to different users The resources need to be mapped in combination with the buffer sizes of different users.
[0030] Assume that in a cell network, the uplink bandwidth is divided into M RBs, and there is...
