US 2022/0038919 A1 · DOWNLINK CONTROL CHANNEL TRANSMISSION AND RECEPTION METHODS, TERMINAL, AND NETWORK SIDE DEVICE

Abstract

A downlink control channel transmission method, a terminal and a network side device are provided. The method includes: selecting, in a case that monitoring occasions of search spaces transmitted in different Control Resource Sets (CORESETs) configured with different beam directions collide, a target CORESET from the different CORESETs according to types of the search spaces where the collision occurs, wherein the collision during the monitoring occasions comprises that the monitoring occasions are the same and configured resources of the different CORESETs overlap, or, that a time interval between the monitoring occasions is less than a specified threshold; and detecting and receiving a downlink control channel according to a beam direction of the target CORESET.

A downlink control channel reception method, applied to a terminal, comprising:

selecting, in a case that monitoring occasions of search spaces transmitted in different Control Resource Sets (CORESETs) configured with different beam directions collide, a target CORESET from the different CORESETs according to types of the search spaces where the collision occurs, wherein the collision during the monitoring occasions comprises that the monitoring occasions are the same and configured resources of the different CORESETs overlap, or, that a time interval between the monitoring occasions is less than a specified threshold;
and
detecting and receiving a downlink control channel according to a beam direction of the target CORESET.

A downlink control channel transmission method, applied to a network side device, comprising:

in a case that occasions of transmissions of a downlink control channel that requires to be performed in different CORESETs configured with different beam directions collide, wherein the collision during the occasions of the transmissions of the downlink control channel comprises:
that the occasions of the transmissions of the downlink control channel are the same and configured resources of the different CORESETs overlap, or, that a time interval between the transmissions of the downlink control channel is less than a specified threshold,
selecting a target CORESET from the different CORESETs according to types of search spaces in the different CORESETs where the collision occurs, and transmitting the downlink control channel according to a beam direction of the target CORESET;
or,
transmitting the downlink control channel in the different CORESETs according to respective beam directions of the different CORESETs.
