1. An electronic apparatus for wireless communications, comprising:
processing circuitry, configured to:
determine a first aperiodic sounding reference signal (SRS) resource whose beam emitting direction is updated by a first medium access control-control element (MAC CE) signaling; and
re-determine, based on information of the beam emitting direction of the first aperiodic SRS resource in the first MAC CE signaling or a second MAC CE signaling, a path loss reference signal for the first aperiodic SRS resource,
wherein, the first aperiodic sounding reference signal resource belongs to a first sounding reference signal resource set and a first path loss reference signal for the first sounding reference signal resource set is on a first serving cell, the second MAC CE signaling is used for linking the first path loss reference signal to a second serving cell, and the processing circuitry is configured to determine the first path loss reference signal on the second serving cell as the path loss reference signal for the first aperiodic sounding reference signal resource, wherein, the first serving cell and the second serving cell are servings cells in carrier aggregation.
