Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

Abstract: Various aspects of the present disclosure generally relate to systems, apparatuses, and methods for beam determination prior to an indication of an activated beam. A user equipment may receive a configuration for one or more transmission configuration indicator (TCI) states; receive downlink control information that schedules a downlink transmission after a time offset; determine, prior to receiving an indication of an activated TCI state of the one or more TCI states, a beam for receiving the downlink transmission; and receive the downlink transmission using the beam. Numerous other aspects are provided.

Abstract: Techniques and apparatus for early termination of decoding of communication channels for power saving in narrowband devices are provided. One technique includes monitoring for one or more first repetitions of at least one communication channel from a base station. The device determines, based on the monitoring, whether to refrain from monitoring for one or more second repetitions of the at least one communication channel. The device enters a low power mode if the determination is to refrain from monitoring for the one or more second repetitions of the at least one communication channel.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving service recovery using communications systems operating according to new radio (NR) technologies. For example, a method may include receiving an uplink transmission from a user equipment (UE) with a Cell Radio Network Temporary Identifier (C-RNTI), determining the C-RNTI lacks context at the network entity, and signaling, in response to the determination, an indication of an immediate C-RNTI release to the UE.

Abstract: Aspects of the present disclosure provide techniques that may be utilized by a UE for performing neighbor cell measurement and reselection in narrowband deployment scenarios, such as NB-IoT deployment scenarios. For example, a method for wireless communications by a user equipment (UE), can include determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters of at least one neighbor cell, and performing a neighbor cell search with measurement of narrowband reference signals (NRS) based on the one or more transmission deployment mode parameters.
