Abstract

The present invention provides an optimization method for sending RLC PDU data on a plurality of logical channels, which mainly includes steps: the UE side calculates the downlink data sequence number received on the first logical channel (AM feedback mode), and the base station sends Whether the terminal has reached the maximum transmission window; if the maximum transmission window has been reached, and there are not enough uplink scheduling resources allocated to the first logical channel, the UE starts the optimization strategy; the MAC first takes out the status of the first logical channel from the buffer queue PDU; if there are no redundant uplink scheduling resources, the MAC will send an enlarged buffer status report to the base station, instructing the base station to increase uplink scheduling resources, so as to quickly restore the uplink transmission rate of the second logical channel. The optimization method for sending RLC PDU data on multiple logical channels provided by the present invention can optimize terminal scheduling strategies on multiple logical channels with different priorities, and prevent single logical channel transmission from stalling.

Description

technical field [0001] The invention relates to multiplexing of multiple logical channels, in particular to an optimization method for sending RLC PDU data on multiple logical channels. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] MAC multiplexing means that the MAC layer is responsible for multiplexing multiple logical channels (logic channels) onto the same transport channel (transport channel). figure 1 A schematic diagram of the relationship between logical channels and transport channels in uplink channel multiplexing and downlink channel multiplexing is shown. The logical channel is located in the channel representation of the second layer (data link layer) transmission in the communication system, and t...
