Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. According to some aspects, the apparatus may identify a first power state and a second power state, wherein the first power state is associated with a first transmission or reception of one or more first beams, and the second power state is associated with a second transmission or reception of one or more second beams; and/or switch from the first power state to the second power state, wherein the apparatus is configured to use at least one of a scheduled gap or at least one intermediate power state between the first power state and the second power state to smooth a transition from the first power state to the second power state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning two or more dimensions of an uplink transmission, where different partitions in each partitioned dimension can be used to provide different feedback information. A UE may measure one or more downlink transmissions from a base station (e.g., beam measurements in a beam sweep procedure), and select a partition of one of the partitioned dimensions to indicate feedback related to the measured downlink transmissions. The feedback may indicate, for example, a particular beam that may be used for an active beam pair, beam refinement information, or other feedback. The partitioned dimensions may include one or more of time resource, a frequency resource dimension, a root sequence dimension, a cyclic shift dimension, a time-frequency dimension, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications between a base station and a user equipment (UE) on multiple carriers. A UE may maintain a connection with a base station on a first carrier (e.g., an anchor carrier), and the UE may use a discontinuous reception (DRX) cycle on a second carrier. The DRX cycle may include scheduled on-durations during which the UE may monitor the second carrier for signaling from the base station. To reduce the power consumption at the UE associated with repeatedly monitoring scheduled on-durations, the base station may transmit wake-up signaling to the UE on the first carrier to identify the on-durations that include data from the base station. Accordingly, the UE may monitor these on-durations for the data and avoid monitoring other on-durations to limit power consumption.

Abstract: A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semi-static signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. Feedback techniques as discussed herein may be used to provide feedback for uplink or downlink transmissions.

Abstract: Wireless communications systems and methods related to synchronization signal (SS) transmission coordination among base stations (BSs) and restricted SS measurements at user equipments (UEs) are provided. A first BS transmits a first SS burst in a first SS transmission period of a plurality of SS transmission periods. The first SS transmission period is designated to the first BS. A second SS transmission period of the plurality of SS transmission periods is designated to a second BS. The first SS transmission period and the second SS transmission period are different. The first BS receives, from a UE, a first signal in synchronization with the first SS burst. The first signal includes a SS measurement of the first SS burst.

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).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive a downlink transmission from at least one beam of a set of beams. The set of beams may be associated with a multi-beam communication between the apparatus and a base station. The apparatus may select a beam, of the set of beams, to report beam related information associated with the at least one beam of the set of beams. The apparatus may report an indication that the beam is a selected beam.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.
