摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

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.
