Title:
METHODS AND APPARATUSES FOR BEAM FAILURE RECOVERY
Document Type and Number:
WIPO Patent Application WO/2022/116148
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to a method and apparatus for beam link recovery (BFR). An exemplary method can include: receiving configuration information indicating: at least one set of failure detection resources, at least including: a first set of failure detection resource associated with a first TRP index and a third set of failure detection resources associated with a secondary cell (SCell); and a set of dedicated periodic physical uplink control channel (PUCCH) resources; in the case that a radio link quality of all failure detection resources in the first set of failure detection resources is lower than a first threshold, transmitting a first positive link recovery request (LRR) in a first dedicated periodic PUCCH resource; and in the case that a radio link quality of all failure detection resources in the third set of failure detection resources is lower than a third threshold, transmitting a third positive LRR in a third dedicated periodic PUCCH resource.
