Abstract

The invention discloses a scheduling and multiplexing method and device for logical channels. The scheduling and multiplexing method is as follows: in the process of multiplexing data units of a plurality of the logical channels to an MAC (medium access control) transmission block according to the priority of each logical channel, if the length of the data unit of the first logical channel is less than a preset threshold, the data unit of the first logical channel is packed to a non-last data packet in the transmission block, and a first MAC sub-header is added for the non-last data packet in the transmission block; and the transmission block is sent to a base station, wherein the length of the first MAC sub-header is less than that of a second MAC sub-header, and the length of the second MAC sub-header is of the length of the MAC sub-header added for the non-last data packet in the transmission block when the length of the data unit of the first logical channel is not less than the preset threshold and the data unit of the first logical channel is packed to the non-last data packet in the transmission block. The scheduling and multiplexing method disclosed by the invention can be conductive to reducing re-distribution of uplink authorization resources during multiplexing of data of an MAC layer, and the utilization rate of resources can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a logical channel scheduling multiplexing method and device. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) project is a transition between 3G and 4G technologies. In the LTE system, before sending uplink data to the evolved base station, the user equipment needs to send an uplink scheduling request to the evolved base station in order to obtain the corresponding Uplink transmission resources. [0003] The eNB (evolved NodeB, evolved base station) determines the data transmission volume of the user equipment according to the received uplink scheduling request, and allocates uplink authorization resources for the user equipment accordingly, so that the UE (User Equipment, user equipment) can use the uplink authorization resources to realize Uplink data transmission. The UE multiplexes data units from multiple logical chan...
