Problems solved by technology

However, in many cases, the base station does not continue to have data to send to the UE, but the UE still needs to continuously monitor or periodically monitor the PDCCH at the position indicated by the CORESET and the search space set. However, not all PDCCHs carry scheduling information. This will cause power consumption

Abstract

Disclosed are a method and device for transmitting control information, which relate to the technical field of communications and can reduce the power consumption of UE. The control information transmission method provided in the embodiments of the present application comprises: a user equipment (UE) receiving first indication information sent by a base station, the first indication information being used for indicating a first time window; and the UE does not monitor a physical downlink control channel (PDCCH) in the first time window.

Description

[0001] This application is a divisional application of the patent application with application number 201810904181.9 titled "A method and device for transmitting control information". technical field [0002] Embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for transmitting control information. Background technique [0003] Currently, 3GPP (the 3rd generation partnership project, third generation partnership project) Release 16 (version 16) proposes to optimize power consumption of NR (new radio, new air interface) user equipment (user equipment, UE). One of the factors causing UE power waste is monitoring of a physical downlink control channel (PDCCH). The base station configures a control resource set (CORESET) and a search space set (search space set) through radio resource control (radio resource control, RRC) signaling to send the PDCCH, and the PDCCH is used to carry data scheduling info...
