Abstract

A method, base station, and user equipment for transmitting random access response (RAR) messages. The method for transmitting the RAR messages comprises: transmitting a first RAR message to a user equipment, where the first RAR message comprises indication information related to a second RAR message; transmitting the second RAR message to the user equipment, where the first RAR message and the second RAR message are transmitted by the base station using different transmission blocks.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method for transmitting a random access response message, a base station, and user equipment. Background technique [0002] In the existing communication system, the user equipment first receives the control channel, determines the size of the transport block (TBS, Transport Block Size) carried by the data channel scheduled by the control channel according to the control information in the received control channel, and determines the transport block size Start receiving data after the size. For example, in a Long Term Evolution (LTE, Long Term Evolution) system, the control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or an enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, EPDCCH), and the data channel may be is a physical downlink shared data channel (PDSCH, Physical...
