Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive an encoded signal including a set of information blocks. Each information block may include a set of encoded information bits and a set of cyclic redundancy check (CRC) bits. The receiving device may perform a staircase decoding procedure to decode the set of encoded information bits of a selected information block that is part of a subset of the set of information blocks that is within a sliding window. The staircase decoding procedure may include one or more iterations of a decoding process applied to the subset of the set of information blocks. The receiving device may perform, inbetween iterations of the staircase decoding procedure applied to the subset of the set of information blocks within the sliding window, a CRC procedure based on the set of CRC bits in the set of information blocks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first orbital angular momentum (OAM) node may transmit a boresight direction alignment reference signal to a second OAM node. The first OAM node may receive, from the second OAM node, a boresight direction alignment status report that indicates boresight direction alignment information based at least in part on the boresight direction alignment reference signal. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for reporting channel state information (CSI). According to certain aspects, a method for wireless communications by a user equipment (UE) generally includes generating channel state information (CSI) comprising a (at least one) fractional rank indication (RI) value for a set of candidate ranks, a first indication of a first layer or first singular vector, and a second indication of a second layer or second singular vector and transmitting the CSI to a network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first indication that the UE is within a distance threshold (e.g., in the near field) of multiple-in multiple-out (MIMO) communications from the base station. The UE may communicate with the base station via signaling including a second indication of antenna panel information of at least one of the UE or the base station, the communication based on the UE being within the distance threshold. The UE may receive, from the base station, a first beamformed signal on one or more first beams within the distance threshold, and the CE may receive, from the base station, one or more second beamformed signals on a second beam within the distance threshold, the second beam based on a channel response matrix that is estimated from the second indication and the first beamformed signal.

Abstract: The position of a target user equipment (UE) is determined using a set of Reference Signal Time Difference (RSTD) measurements that includes at least three RSTD measurements generated at different times by the target UE. Each RSTD measurement is produced based on positioning reference signals (PRS) transmitted by a stationary anchor entity and corresponding PRS transmitted by a moving mobile anchor entity. At least two anchor-to-anchor receive-transmit (RxTx) time difference measurements are generated by an anchor entity, wherein each anchor-to-anchor RxTx time difference measurement is associated with the RSTD measurements, and there are fewer anchor-to-anchor RxTx time difference measurements than RSTD measurements. The position estimate of the target UE is determined based on the set of RSTD measurements and the at least two anchor-to-anchor RxTx time difference measurements.

Abstract: In certain scenarios, resource preemption may occur. A user equipment (UE) is configured to monitor for a preemption indication based on a specific downlink configuration. This configuration provides information about whether preemption is identified within a data space in terms of resource blocks. The UE receives data transmissions from a base station at different times and a preemption indication in a group common physical downlink control channel. Based on this preemption indication and the downlink configuration, the UE determines if a portion of the shared downlink resources occupied by the initial data is preempted from use. If the resources are not preempted, the UE proceeds to decode the initial data.

Abstract: An orbital angular momentum (OAM) antenna includes two or more concentric antenna arrays, each of the antenna arrays corresponding to one or more OAM orders and including a different respective set of antenna elements arranged at a different respective radius, a difference between respective radii of each pair of adjacent antenna arrays of the two or more concentric antenna arrays decreasing as antenna array indexes associated with the respective pair of adjacent antenna arrays increase, each of the antenna array indexes satisfying a threshold index condition. The OAM antenna also includes two or more phase shifters, each of the phase shifters corresponding to a different respective antenna array of the two or more concentric antenna arrays and configured to trigger the respective set of antenna elements of the corresponding antenna array to generate a respective OAM beam

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a base station may transmit, to a user equipment (UE), control signaling indicating a configuration for transmitting a reference signal for reconfigurable surface configuration. The base station may receive, via a reconfigurable surface, the reference signal based on transmitting the control signaling. For instance, the reconfigurable surface may reflect the reference signal to the base station using a first configuration of the reconfigurable surface. The base station may transmit, to a controller of the reconfigurable surface, a set of parameters for configuring the reconfigurable surface to a second configuration for communications between the base station and the UE based on receiving the reference signal via the reconfigurable surface.

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.
