Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a first physical random access channel (PRACH) transmission that includes a first random access (RA) preamble to a base station. The apparatus may determine whether to transmit to the base station a second PRACH transmission that is concurrent with the first PRACH transmission in time, wherein the second PRACH includes a second RA preamble. The apparatus may transmit, to the base station, the second PRACH transmission that includes the second RA preamble when the second PRACH transmission is determined to be transmitted. The first RA preamble and the second RA preamble may be different, and the first RA preamble and the second RA preamble may be concurrently transmitted in a same PRACH occasion or in different PRACH occasions that overlap in time.

Abstract: Aspects of the present disclosure describe transmitting beams in wireless communications. A plurality of downlink beams having different beamforming directions can be received from a base station. Downlink pathloss values associated with each of the plurality of downlink beams can be measured. A transmit power for transmitting a plurality of uplink beams can be determined based on at least one of the downlink pathloss values. The plurality of uplink beams in multiple beamformed directions can be transmitted based on the transmit power.

Abstract: Certain aspects of the present disclosure provide techniques for determining when to transmit and transmitting an aperiodic tracking reference signal (TRS). Certain aspects provide a method for wireless communication. The method generally includes determining a channel condition change of a downlink channel between a first wireless device and a second wireless device. The method further includes determining whether the channel condition change satisfies a trigger condition. The method further includes triggering transmission of an aperiodic tracking reference signal when the channel condition change satisfies the trigger condition.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink power control. Certain aspects provide a method for performing uplink power control at a base station (BS). The method includes determining a first configuration of one or more parameters for uplink power control at a user equipment (UE) based on a first spatial beam selected, from a plurality of spatial beams, for uplink communication of the UE. The method further includes transmitting a first indication of the first configuration to the UE.

Abstract: Aspects of the present disclosure relate to receiver beamforming management procedures. According to certain aspects, beams from the set of beams configured at the user equipment (UE) may be not recovered, deleted, removed, and/or merged. A method by a UE includes communicating with a base station using a set of beams. The UE receives signaling, from the base station, indicating one or more beams of the set to be removed from the set and updates the beams in the set based on the signaling.

Abstract: Aspects of the present disclosure implement techniques to allow a base station to transmit a “short-page” message (e.g., paging indicators) to one or more UEs. The short-page message may be decoded by all UEs in the paging cycle and identifies a subset of UEs from the full set of UEs that are paged by the base station. Upon decoding the short page transmitted by the base station, the UE may respond with a “short-page response” to the base station on a transmit beam that offers best signal quality (e.g., low signal-to-noise ratio, transmit power, etc.). Thus, in some examples, the UE, in response to receiving a short paging message, may provide feedback to the base station such that the base station may select a transmit beam for transmission for a subsequent message (and other communications).
