Abstract

The embodiment of the invention provides a downlink channel receiving method, a downlink channel sending method, a terminal and a base station. The method comprises the following steps of: obtaining asample; determining a TCI state of a downlink control channel, wherein the TCI state is the TCI state of a control resource set CORESET used by the terminal on the original BWP last time under the condition that the terminal is switched back to the original bandwidth part BWP, and the downlink control channel is sent on the CORESET of the original BWP; and receiving the downlink control channel according to the TCI state. According to the embodiment of the invention, the reliability and accuracy of data transmission can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a downlink channel receiving method, sending method, terminal and base station. Background technique [0002] Fifth generation (5 th generation, 5G) communication system, the operating frequency band supported by the system is increased to above 6GHz, and the maximum is about 100GHz, so that multi-beam transmission is adopted in the 5G communication system. For multiple beam transmissions, in the 5G communication system, beam information may be indicated to the terminal through a transmission configuration indication (Transmission Configuration Indication, TCI) state. In addition, in the 5G communication system, the maximum channel bandwidth (channel bandwidth) of each carrier is 400MHz, while the maximum bandwidth supported by the terminal can be less than 400MHz, so the bandwidth part (BWP) is newly introduced in the 5G communication system. Concept, UE can...
