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: 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.
