Problems solved by technology

However, the number of PDCCH candidates configured in each time length may exceed the number of PDCCH candidates that the terminal device can monitor within this time length. At this time, the terminal device may not be able to reasonably monitor the necessary PDCCH candidates, such as low delay and high reliability. PDCCH candidates for business (ultra-reliable and low-latency communications, URLLC)

Abstract

The invention provides a communication method and equipment. The method comprises the steps that terminal equipment determines a PDCCH candidate which does not need to be monitored in a first search space of a first time span from configured PDCCH candidates, and the first time span is one or more time spans in the first time span, the terminal equipment determine which PDCCH candidates do not need to be monitored when the number of the configured PDCCH candidates is within a specific numerical range. Through the selective monitoring scheme taking the PDCCH candidate as the granularity, the PDCCH can be monitored more flexibly.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a communication method and device. Background technique [0002] In the new radio (NR) communication system, in order to improve the flexibility of scheduling, the network equipment will flexibly configure the search space (search space, SS) for the terminal equipment, and the terminal equipment monitors the physical downlink control channel (physical SS) in the search space. downlink control channel (PDCCH) candidate (candidate). However, the number of PDCCH candidates configured in each time length may exceed the number of PDCCH candidates that the terminal device can monitor within this time length. At this time, the terminal device may not be able to reasonably monitor the necessary PDCCH candidates, such as low delay and high reliability. A PDCCH candidate for a service (ultra-reliable and low-latency communications, URLLC). Contents of the invention [0003]...
