Abstract

The present invention provides a downlink control channel transmission method, a terminal, and a network side device, belonging to the field of communication technology, wherein a method includes: when the monitoring time of the search space transmitted in different CORESETs configured with different beam directions conflicts, according to The type of conflicting search space, select the target CORESET from the different CORESETs, the monitoring time conflict occurs because the monitoring time is the same and the resources configured by different CORESETs overlap, or the time interval between the monitoring time is less than the specified threshold; according to the beam of the target CORESET Direction detection and reception of downlink control channels. The present invention solves the problem of the behavior of the terminal and the base station when different CORESETs configured with different beam directions need to detect the downlink control channel at the same time and the configured resources overlap, or when the downlink control channel needs to be detected at adjacent times with small intervals There is no clearly defined problem.

Description

A downlink control channel transmission method, terminal and network side device technical field The present invention relates to the field of communication technologies, and in particular, to a method for transmitting a downlink control channel, a terminal and a network side equipment. Background technique CORESET (control- The concept of resource set, control resource set), the time domain resource of CORESET consists of 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing technology) symbols, the frequency domain pass length is 45 The bitmap (bitmap) indicates a continuous or discrete multiple RB (Resource Block) granularity of six consecutive RBs. A resource group, resource configuration is very flexible. Search spaces with different listening periods are in the same or different CORESETs transmission. Each CORESET can be configured with beam directions independently, that is, different CORESETs can be configur...
