Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to rate matching for new radio (NR) physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH). In certain aspects, a method includes receiving a rate matching resource (RMR) configuration from a serving cell. The method also includes identifying one or more first resource elements (REs) to be rate matched around at least in part based on a transmission numerology associated with the RMR configuration, wherein the one or more first REs are used for reference signal (RS) transmission in the serving cell or a neighboring cell. The method further includes mapping a physical downlink shared channel (PDSCH) to one or more second REs not including the first REs.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In some aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) implement a timer (e.g., a round-trip time (RTT) timer) during which it does not monitor a physical downlink control channel (PDCCH). The UE may initiate the timer after transmitting a first random access message or a four-step random access message, or transmitting or retransmitting a third random access message of a four-step random access procedure, or after a physical uplink control channel (PUCCH) resource for hybrid automatic repeat request (HARQ) feedback for a fourth message of a four-step random access procedure. The UE may initiate the timer after transmitting a first message of a two-step random access procedure, or after a PUCCH resource for HARQ feedback for a second message of a two-step random access procedure, or after a fixed offset from the end of a PDSCH of a two-step random access procedure.

Abstract: Methods and apparatus for constructing polar codes are provided. A transmitter determines at least one set of parameters corresponding to data to be transmitted, and a set of sorting indices corresponding to bits of the data to be transmitted based on the set of parameters, the set of sorting indices indicating a position set of the bits to be transmitted. The transmitter polar encodes the data based at least on the set of parameters and the set of sorting indices to generate a coded block of the data, and transmits the coded block of the data.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.
