Title:
METHOD AND APPARATUS FOR REDUCING OPERATIONS OF MONITORING PDCCH
Document Type and Number:
WIPO Patent Application WO/2021/138906
Kind Code:
A1
Abstract:
Embodiments of the present application relate to a method and an apparatus for reducing operations of monitoring PDCCH. According to an embodiment of the present application, a method can include: receiving configuration information indicating a plurality of search space sets and an activation or deactivation state for each search space set of the plurality of search space sets; and receiving an activation-deactivation indication in first downlink control information (DCI) in a first search space set in an activation state of the plurality of search space sets, wherein the activation-deactivation indication is configured to: trigger switching at least one second search space set of the plurality of search space sets from a deactivation state to an activation state; or trigger switching the at least one second search space set of the plurality of search space sets from an activation state to a deactivation state. Embodiments of the present application can save power and enhance the battery lifetime for the NR-Light UEs.
