More Information
Summary:A method of updating spatial parameters for a UE is provided. The method includes receiving, from a network, at least one configuration for one or more serving cells; receiving, from the network, a BFR configuration applicable for a serving cell of the one or more serving cells; detecting a beam failure in the serving cell of the one or more serving cells; transmitting, to the network, a request for a BFR in the serving cell, the request indicating a DL RS or being associated with the DL RS; receiving, from the network, a response corresponding to the transmitted request; receiving, after receiving the response, one or more CORESETs in the serving cell via a spatial RX parameter derived from the DL RS; and transmitting, after receiving the response, one or more PUCCH resources in the serving cell via a spatial TX parameter derived from the DL RS.
