Abstract: Systems, methods, and apparatuses for sounding reference signal (SRS) management in carrier aggregation (CA) are described. A user equipment (UE) may be scheduled for overlapping (e.g., concurrent) transmissions of SRS and uplink control or data on different cells of a CA configuration. In some cases, the SRS transmission may be dropped (e.g., the UE may refrain from transmitting a scheduled SRS). While in some cases, the UE may transmit both SRS and another uplink message in overlapping time intervals on different cells (e.g., SRS may be transmitted concurrently with another uplink message). A determination of whether to transmit or drop SRS may be based on whether the different cells have different cyclic prefix (CP) lengths or on whether the SRS is scheduled to be transmitted in a special subframe of a time division duplexing (TDD) configuration, for example.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE beam selection based on service demands are disclosed herein. An example method of wireless communication includes determining to select an UL beam having a higher EIRP capability than an EIRP capability associated with a current beam for transmitting on UL when at least one of a target transmit power based on a TPC exceeds an EIRP capability associated with the current beam or when an amount of data in a buffer of the UE is greater than a data threshold. The example method also includes determining, upon determining to select the UL beam, a set of UL beams with an EIRP capability satisfying an EIRP capability threshold and a respective beamforming direction corresponding to a beamforming direction associated with the current beam, selecting one UL beam of the set of UL beams, and transmitting on UL on the selected UL beam.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.
