Abstract: Certain aspects of the present disclosure provide techniques for beam refinement procedures including dynamic signaling and/or selection of beam-switching latency for beam refinement procedures using inter- and/or intra-antenna module beam switching. A method by a base station (BS) includes configuring a user equipment (UE) with one or more reference signal (RS) resource sets. Each of the one or more RS resource sets is associated with a first or second type of beam refinement procedure. The BS receives an indication from the UE of at least a first latency and a second latency, longer than the first latency. The BS dynamically selects, for each RS transmission using one of the configured resource sets, the first or second latency. The BS sends the RS transmissions at the selected latency with respect to downlink control information (DCI) triggering the RS transmissions for the first or second type of beam refinement procedure.

Abstract: A method, apparatus, and computer-readable medium are provided that improve decoding of downlink data that has been rate matched around aperiodic tracking reference signals, e.g., aperiodic CSI-RS. A UE receives a downlink control channel scheduling a downlink data channel. The downlink control channel may comprise an indication of a zero-power channel state information-reference signal (ZP CSI-RS) configuration from a base station. The UE receives the downlink data channel that is rate matched around CSI-RS resources indicated in the ZP CSI-RS configuration and decodes the downlink data channel based on the indication of the ZP CSI-RS configuration received from the base station.

Abstract: Aspects of the present disclosure relate to techniques for multibeam PDCCH monitoring during CDRX operations. A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

Abstract: Various aspects described herein relate to techniques for signaling and using one or more virtual cell identifications (V-cell IDs) for single frequency network (SFN)-type of transmissions in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method may include performing, by a user equipment (UE), a cell search to obtain a cell ID, and decoding, by the UE, a message based on the cell ID, wherein the message includes a master information block (MIB). The method may further include identifying, by the UE, a virtual cell ID used for SFN-type transmissions based on information decoded from the message. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for beam sweeping for control and data transmissions. In certain aspects, the method for use by a first wireless communications device includes determining one or more beams in a sequence of beams for use in sending or receiving directional transmissions to a second wireless communications device and sweeping through the one or more beams in the sequence of beams for transmissions to or from the second wireless communications device between beamforming training procedures performed with the second wireless communications device.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, multi-link PDCCH monitoring. A UE may receive signaling configuring it to operate in at least one of a set of different modes of monitoring beam-pair links, wherein each beam-pair link comprises a transmit beam configured to be used by a base station (BS) for beamformed transmissions and a corresponding receive beam used by the UE. The UE may monitor at least two or more beam-pair links for downlink control channel transmissions based, at least in part, on the received signaling, and may transmit feedback to the BS based, at least in part, on the monitored beam-pair links.

Abstract: Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.
