Abstract: An apparatus for wireless communication is provided. The apparatus may be a receiver device that includes an error correction decoder, such as a low-density parity check (LDPC) decoder. The apparatus may achieve power savings and/or operation cycle savings by disabling the error correction decoder in scenarios where bits of a codeword in a signal transmission are received without errors. The apparatus obtains a first set of bits of a codeword, wherein the codeword includes the first set of bits and a second set of bits, and wherein the second set of bits is punctured. The apparatus recovers the second set of bits based on at least the first set of bits and determines whether to operate an error correction decoder based on a result of an error detection operation performed on the codeword using the first set of bits and the second set of bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a base station, an indication of a relaxed physical downlink shared channel (PDSCH) hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback timeline associated with a dynamic spectrum sharing (DSS) deployment in which a first radio access technology (RAT) and a second RAT share a same frequency band. The mobile station may receive, from the base station, a PDSCH associated with the first RAT. The mobile station may transmit, to the base station, PDSCH HARQ-ACK feedback for the PDSCH associated with the first RAT based at least in part on the relaxed PDSCH HARQ-ACK feedback timeline associated with the DSS deployment. Numerous other aspects are described.

Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.
