Embodiment Construction
[0037] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0038] The present invention proposes that the RLC layer reports the size of each RLC SDU that each logical channel needs to transmit to the MAC layer, and limits the number of bits that each logical channel of each UE can transmit within a subframe at the MAC layer, and Only an integer number of RLC SDUs are allocated resources to finally determine the number of bits that each logical channel can transmit in a subframe. This method effectively reduces the retransmission fragmentation probability caused by too large RLC SDUs during retransmission by limiting the size of the newly transmitted RLC PDU, and also effectively prevents the RB resources of a subframe from being occupied by a UE; and The MAC layer only allocates resources for an integer number of RLC SDUs, which also effectively reduces the fragmentation pro...
