Embodiment Construction

[0027] As described in the background art, in the prior art, PDCCH search space switching may be triggered by a specific DCI, and PDCCH skipping may also be indicated by a specific DCI. Both of the above two types of PDCCH monitoring reduction methods may include multiple states, that is, multiple DCI bits are required to indicate multiple states, resulting in a large downlink overhead.

[0028] In the embodiment of the present invention, at least one of PDCCH search space switching and PDCCH skipping can be instructed through an indication field in the downlink control information, thereby reducing DCI downlink overhead when implementing PDCCH search space switching and PDCCH skipping.

[0029] In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] An embodiment of the present inven...

Abstract

A method and apparatus for indicating physical downlink control channel monitoring, and a medium, the method comprising: receiving downlink control information, the downlink control information comprising at least one indication domain, the at least one indication domain being used for indicating at least one of the following: physical downlink control channel search space switching, and physical downlink control channel monitoring skipping; and executing corresponding operation on physical downlink control channel monitoring according to the at least one indication domain in the downlink control information. According to the scheme, the DCI downlink overhead can be reduced when the PDCCH search space is switched and the PDCCH skipping is carried out.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for indicating physical downlink shared channel monitoring, and a readable storage medium. Background technique [0002] The battery life of User Equipment (UE) is an important aspect of user experience, which will affect the usage experience of 5G devices and / or services. To this end, the 5G system introduces some techniques to indicate changes in UE behavior, so that the UE can enter a power saving state under appropriate conditions to save UE power. The switching of this state involves a variety of configuration changes, including Bandwidth Part (BWP) switching (switching to a smaller BWP), switching of the physical downlink control channel (Physical Downlink Control Channel, PDCCH) detection period (switching to a larger period), skipping part of the PDCCH monitoring ( PDCCH monitoring skipping) and cross-slot scheduling with a...
