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 wireless communication. In some aspects, a user equipment (UE) may receive a first configuration for a sounding reference signal (SRS) to be transmitted on a sub-band full duplex (SBFD) resource. The UE may receive a second configuration for the SRS to be transmitted on a non-SBFD resource. The UE may apply one of the first configuration or the second configuration based, at least in part, on whether the SRS is on one of the SBFD resource or the non-SBFD resource. Numerous other aspects are described.

Abstract: A method and apparatus for a reflective intelligent surface (RIS) control interface. The apparatus transmits, to a RIS, a synchronization signal to establish a level of synchronization between the base station and the RIS. The level of synchronization between the base station and the RIS configures the RIS to receive a control signal from the base station. The apparatus transmits, to the RIS, the control signal comprising a RIS configuration. The apparatus may transmit, to the RIS, a signal for reflection by the RIS to at least a first wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first medium access control control element (MAC-CE) that, alone or with a second MAC-CE, specifies one or more transmission control indicator (TCI) states for a first control resource set (CORESET) identifier (ID) that corresponds to a first transmit receive point (TRP) and one or more TCI states for a second CORESET ID that corresponds to a second TRP. The UE may update spatial relation information for the UE based at least in part on the first MAC-CE. The UE may receive signals from the first or second TRP using the updated spatial relation information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Neural networks may assist user equipments (UEs) and base stations in performing various operations related to wireless communications. For example, neural networks may be used to generate non-orthogonal cover codes for transmitting reference signals such as channel state information-reference signals (CSI-RSs). A base station may transmit, to a UE, a CSI-RS associated with a non-orthogonal cover code of a set of non-orthogonal cover codes. Using the CSI-RS, the UE may perform a channel estimation procedure that corresponds to the non-orthogonal cover code. Based on the channel estimation procedure, the UE may transmit a feedback message to the base station that indicates a channel quality parameter. Additionally, or alternatively, a UE may receive a CSI-RS, determine a precoding matrix using the CSI-RS and neural network, and transmit an indication of the pre-coding matrix to a base station.
