Abstract: Methods, systems, and devices for wireless communications are described. One method for providing a wake-up signal to user equipments (UEs) that support multiple multicast sessions may include a base station transmitting configuration information to a UE indicating a wake-up signal configuration for one or more multicast sessions. Accordingly, the UE may monitor the one or more multicast sessions for a wake-up signal and receive, prior to an active duration of a multicast session, a wake-up signal from the base station. The wake-up signal may include control signaling indicating to the UE which of a set of multicast sessions the UE is to monitor. The UE may determine which multicast sessions to monitor based on the received control signaling.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Certain aspects of the present disclosure provide techniques for narrowband transmissions with finer granularity of reserved resources. A method that may be performed by a user equipment (UE) includes receiving a configuration indicating first resource elements (REs) reserved from being used for narrowband Internet of things (NB-IoT) transmissions in a subframe; determining second REs, in the subframe, for narrowband reference signals (NRSs), based on the configuration; and processing the NRSs on the second REs in the subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone. The UE may transmit uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing for fine granularity CSI. A method for wireless communications by a user equipment (UE) includes receiving a CSI reporting configuration. The CSI reporting configuration includes a number of frequency domain (FD) units and a FD unit size for CSI reporting. The UE determines a number of CSI processing units at the UE to use for processing the CSI report based on the number of FD units or the FD unit size for the CSI report. The UE processes the CSI report based on the determined number CSI processing units. In another method, the UE determines at least one threshold to use for determining whether to update a CSI report based on the number of FD units or the FD unit size for CSI reporting.

Abstract: Certain aspects of the present disclosure provide techniques for layer mapping for multiple transmission reception point (TRP) transmission, for example, for code block group (CBG) based hybrid automatic repeat request (HARQ) acknowledgement feedback in new radio (NR). Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The UE receives one or more transport blocks (TBs) from a plurality of TRPs. Each of the one or more TBs comprises a plurality of CBs. For one or more of the plurality of CBs, all bits of the CB are received from a same TRP. The UE decodes the one or more TBs.

Abstract: Certain aspects of the present disclosure provide techniques for generating and using channel state information reference signals (CSI-RS). In some aspects, a method for generating a Channel State Information-Reference Signal may include: generating a pseudo-random base sequence based on at least a time parameter of the CSI-RS; modifying the pseudo-random base sequence based on at least a frequency parameter of the CSI-RS to form a modified pseudo-random sequence; generating the CSI-RS based on the modified pseudo-random sequence; and transmitting the CSI-RS to a user equipment.

Abstract: Methods, systems, devices, and apparatus for wireless communication are described that relate to transmission of a set of precoded reference signals, and using a physical resource group (PRG) size for the resources carrying the set of reference signals for channel estimation at a user equipment (UE). For example, a base station may apply a precoding matrix to a set of reference signals, and the reference signals may be configured on a set of resources. In such cases, the resources including these reference signals having a same precoding may be included in a PRG, and a size of the PRG may refer to a number of precoded reference signals for which the precoding is the same. Based on the received reference signals and the PRG size the UE may perform channel estimation based on the PRG size and transmit channel state information (CSI) to the base station.
