Abstract: Certain aspects of the present disclosure provide a technique for parallel distribution matching (DM) encoding. A user equipment (UE) implements the technique to perform a first round of parallel DM encoding using k information bits as input by: 1) segmenting the k information bits into N blocks of information bits, and 2) encoding the N blocks of information bits in parallel with N DM blocks. Each of the N blocks outputs one or more encoded information bits in each of the NDM blocks, and a total number of information bits output by the N DM blocks is less than k. The UE then performs a second round of parallel DM encoding using k′ information bits that were not encoded in the first round of DM encoding. The second round of parallel DM encoding includes a same encoding process as implemented in the first round of parallel DC encoding.

Abstract: Certain aspects of the present disclosure provide techniques for allocating channel state information (CSI) processing unit (CPU) for user equipment (UE) initiated CSI. For example, the UE may receive an indication from a network entity (e.g., a base station or gNB) configuring the UE with a number of one or more CPUs allowed to be occupied for UE-initiated CSI feedback. The UE uses the at least one of the CPUs to calculate UE-initiated CSI feedback. The UE transmits at least one report including the UE-initiated CSI feedback if one or more conditions are met, such as when a mismatch between a CSI metric for a scheduled physical downlink shared channel (PDSCH) and a CSI metric calculated as part of the UE-initiated CSI feedback is equal to or exceeding a threshold value.

Abstract: Apparatus, methods, and computer-readable media for facilitating distribution matching via reversed compression are disclosed herein. An example method for wireless communication at a wireless transmitter includes decompressing a first sequence of information bits for wireless transmission to output a sequence of shaped symbols. The example method also includes compressing the sequence of shaped symbols to output a second sequence of compressed information bits. The example method also includes transmitting, to a receiver, a signal comprising the sequence of shaped symbols.

Abstract: Methods, systems, and devices for power backoff techniques for modulation schemes are described. A user equipment (UE) may receive an indication of a constellation distribution parameter and a modulation scheme to be used by the UE for an uplink message on an uplink channel. The UE may determine an uplink transmission power based at least in part on the indicated constellation distribution parameter and the indicated modulation scheme. The UE may transmit the uplink message using the indicated modulation scheme according to the determined uplink transmission power. In some examples, the UE may transmit a report indicating a power headroom parameter and an output power parameter based at least in part on the constellation distribution parameter.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, from a transmitting device, a configuration indicating a set of orbital angular momentum (OAM) modes for joint reporting, where at least one of the set of OAM modes is associated with transmission via two or more of a plurality of sets of antennas arranged in a set of concentric circular arrays. The receiving device may transmit, to the transmitting device, a report indicating precoding information for each of at least a subset of the set of OAM modes, where the precoding information includes one or more first parameters common to the set of OAM modes and one or more second parameters for respective ones of the at least the subset of the set of OAM modes.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for configuring CSI-RS repetitions for CSI measurement in high Doppler scenarios. An example method generally includes receiving, from a network entity, a configuration identifying channel state information (CSI) reference signal (RS) (CSI-RS) repetitions over which a CSI report is to be generated, receiving CSI-RS repetitions according to the configuration, measuring CSI based on the received CSI-RS repetitions, and transmitting the CSI report including the measured CSI to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may receive one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device. The transmitting device may encode, at the L2 layer, the one or more SDUs according to one or more network coding parameters to obtain at least one encoded protocol data unit (PDU), the one or more network coding parameters comprising a rateless code. The transmitting device may generate, for the at least one encoded PDU, at least one corresponding PDU header. The transmitting device may output the at least one encoded PDU and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be a user equipment (UE), may receive a message including an indication of a set of demodulation reference signal (DMRS) candidates for a data channel. The data channel may be a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) in some examples. The UE may determine a set of parameters associated with the set of DMRS candidates based on the received message. The set of parameters may correspond to a radio frequency spectrum subband or a radio frequency spectrum band associated with the data channel. The UE may estimate one or more characteristics of the data channel using the set of parameters associated with the set of DMRS candidates to perform wireless communication (e.g., PDSCH reception, PUSCH transmission).
