Abstract: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics

Abstract: A user equipment may be configured to perform beam failure detection enhancement. In some aspects, the user equipment may receive a beam failure detection reference signal (BFD-RS) from a base station, detect an occurrence of an interference event based on a first measurement of the BFD-RS or a channel event based on a second measurement of the BFD-RS, and update count information based on a detection function and the occurrence. Further, the user equipment may determine that at least one of a first timer for interference events or a second timer for channel events is active, and determine whether to perform a beam failure recovery process based on comparing a total count of the count information to a predefined threshold value.

Abstract: Certain aspects of the present disclosure provide techniques for application of a repetition factor to uplink (UL) control channels. A method that may be performed by a user equipment (UE) includes receiving, on a downlink (DL) control channel, an indication of a configuration for repetition of a UL control channel scheduled by the DL control channel and another UL control channel, wherein the configuration is applied for repetition of the other UL control channel after a configured time period starting from reception of the DL control channel; and transmitting the repetition of the UL control channel and the repetition of the other UL control channel in accordance with the configuration.

Abstract: Techniques and apparatus for providing hybrid automatic repeat request (HARQ) feedback for multiple physical downlink shared channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) scheduling a plurality of downlink data transmissions across a plurality of slots. The plurality of downlink data transmissions are monitored across the plurality of slots. At least one HARQ feedback scheme for acknowledging the plurality of downlink data transmissions is determined. HARQ feedback for the plurality of downlink data transmissions is provided in accordance with the at least one HARQ feedback scheme.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

Abstract: A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.

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, a first indication of at least one first downlink reference signal. Accordingly, the UE may measure, using a first antenna panel of the UE, the at least one first downlink reference signal. The UE may transmit, to the base station, a report based at least in part on measuring the at least one first downlink reference signal using the first antenna panel. Numerous other aspects are provided.

Abstract: A UE may receive, from a base station, a first and second configurations of first and second periodic resources, receive, from the base station, a metric for switching between the first and second configurations, and switching from the first configuration to the second configuration based on the metric received from the base station. The first and second configurations may be CG of uplink resources for uplink channels. The first and second configurations may indicate SPS resources for downlink channels. The base station may determine the metric based on at least one measurement of signal at the base station or scheduling requirements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a secondary cell group (SCG) is to enter an SCG dormant state and an indication for using one or more of configured grant (CG) on an uplink or semi-persistent scheduling (SPS) on a downlink for communication with a secondary node (SN) of the SCG during the SCG dormant state. The UE may communicate with the SN of the SCG during the SCG dormant state using the one or more of CG or SPS. Numerous other aspects are provided.

Abstract: In embodiments of systems and methods for managing communication between a wireless device and a base station, a base station may transmit Remaining Minimum System Information (RMSI) Downlink Control Information (DCI) indicating time and frequency resources for RMSI. A wireless device may receive a Channel State Indicator-Reference Signal (CSI-RS) based on the time and frequency resources for RMSI and may select a sub-beam of a beam associated with a synchronization signal block (SSB). The wireless device may send to the base station an indication of the selected sub-beam associated with the SSB in a Physical Random Access Channel (PRACH) message. The base station and the wireless device each may then perform an initial access procedure using the selected sub-beam to enable the wireless device to establish a communication link with the base station.
