Abstract: Certain aspects of the present disclosure provide methods for adapting one or more parameters for uplink transmissions based on a channel condition profile. An example method generally includes obtaining, from a base station, feedback relating to one or more uplink transmissions sent from the UE to a base station (BS); generating, based on the feedback, a channel condition profile of one or more channels associated with the one or more uplink transmissions; and taking one or more actions, based on the channel condition profile, to adjust at least one of a power, code rate, or modulation scheme for one or more subsequent uplink transmissions.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing random access channel (RACH) procedures with a base station. For example, certain aspects provide methods and apparatus for performing RACH procedures when a user equipment moves out of range from the base station (e.g., for RACH procedure success). One method includes attempting a RACH procedure with a first base station, determining the UE is out of range from the first base station for RACH procedure success, and, upon determining the UE is out of range from the first base station for RACH procedure success, reattempting the RACH procedure with the first base station or a second base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment receives a sliding window of measurements associated with a radar signal transmitted by the UE; determines that a user is within a threshold distance of the UE, wherein the threshold distance is determined to be a first distance when an energy measurement, associated with the radar signal, indicates an energy reduction satisfying a threshold energy reduction, or wherein the threshold distance is determined to be a second distance when the sliding window of measurements indicates an amount of energy variation satisfying a threshold amount of energy variation associated with the radar signal; and performs, based at least in part on determining that the user is within the threshold distance, an action associated with a communication signal of the UE. Numerous other aspects are provided.

Abstract: A method, a computer-readable medium, and an apparatus are disclosed for energy efficient multichannel communications. In one aspect, the apparatus may communicate using a plurality of channels working in parallel where the plurality of channels may share an LNA. Additionally, the apparatus may determine a set of parameters for the plurality of channels to maximize energy efficiency. The apparatus may therefore configure the plurality of channels based on the set of parameters. As such, the apparatus supports multichannel communications with a common LNA structure while providing energy optimization for the multichannel communications. Accordingly, multichannel communications can be provided using a shared LNA structure that reduces implementation cost and more efficiently utilizes available power resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a set of component carriers (CCs) associated with the UE. The UE may receive, from the base station, a message that activates or deactivates one or more CCs of the set of CCs. The UE may communicate, with the base station, after receiving the message, using one or more activated CCs of the set of CCs over a tuned radio frequency (RF) bandwidth that is based on receiving the message and based on the one or more activated CCs. Numerous other aspects are provided.
