A method and terminal for monitoring downlink control information

Abstract

A downlink control information monitoring method and terminal, which are applied in the field of communication technology, to solve the problems in the prior art that the configuration of the discontinuous reception cycle is fixed, the activation period is configured too short, resulting in low service efficiency, and the activation period is configured If it is too short, it will cause a technical problem of excessive service power consumption. The method includes: the terminal monitors the downlink control information according to the first rule in the first time resource unit interval; the terminal monitors the downlink control information according to the second rule in the second time resource unit interval; the first time The resource unit interval is different from the second time resource unit interval, and the first rule is different from the second rule. Compared with the existing LTE DRX technology, if the DRX activation period is the same, the present application can reduce the frequency of the terminal monitoring downlink control information and reduce the energy consumption of the terminal. If the times of monitoring are the same, the present application can extend the duration of the DRX activation period to make scheduling more flexible.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and a terminal for monitoring downlink control information. Background technique [0002] In long term evolution (LTE) or new communication (new radio, NR) protocols, packet-based data flow is usually bursty, with data transmission for a period of time, but a longer period in the next There is no data transfer for that time. When there is no data transmission, power consumption can be reduced by stopping receiving a physical downlink control channel (PDCCH), thereby improving battery life. In LTE, this is achieved using discontinuous reception (DRX). In LTE, the basic principle of DRX is that a UE in a radio resource control (radio resource control, RRC) connected state is configured with a discontinuous reception cycle. Such as figure 2 As shown, a discontinuous reception DRX cycle is composed of an active period "On Duration" and a dormant pe...
