Method and Apparatus for Determining Physical Uplink Channel Power Control Parameter Values for Use After a Beam Failure Recovery

摘要

A method and apparatus is provided for determining physical uplink channel power control parameter values for use after a beam failure recovery. A physical random access channel with a spatial domain transmission filter associated with a selected downlink reference signal from a set of downlink reference signals configured for a link recovery is transmitted. A determination is made as to whether the selected downlink reference signal is configured for at least one of a set of uplink spatial relation configurations as a reference signal for an uplink spatial relation setting for a physical uplink channel transmission. A power control parameter value for the physical uplink channel transmission is determined. The physical uplink channel is transmitted with the spatial domain transmission filter associated with the selected downlink reference signal and the determined physical uplink channel power control parameter value.
