Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a physical downlink shared channel (PDSCH) transmission in one or more of a half-duplexing mode or a full-duplexing mode. The UE may attempt to decode the PDSCH transmission using a low-density parity-check (LDPC) decoder. The UE may transmit, to the base station, feedback that indicates a difference between a half-duplex channel quality and a full-duplex channel quality based at least in part on one or more decoding parameters associated with the LDPC decoder. Numerous other aspects are described.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a base station, a physical downlink shared channel (PDSCH) transmission comprising one or more blocks, each block of the one or more blocks being received in either a half-duplexing mode or a full-duplexing mode;
- attempt to decode the PDSCH transmission using a low-density parity-check (LDPC) decoder;
- and
- transmit, to the base station, feedback that indicates a difference between a half-duplex channel quality and a full-duplex channel quality based at least in part on one or more decoding parameters associated with the LDPC decoder.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit, to a user equipment (UE), a first physical downlink shared channel (PDSCH) transmission comprising one or more blocks, each block of the one or more blocks being transmitted in either a half-duplexing mode or a full-duplexing mode;
- receive, from the UE, feedback that indicates a difference between a half-duplex channel quality and a full-duplex channel quality based at least in part on one or more decoding parameters associated with a low-density parity-check (LDPC) decoder used to decode the first PDSCH;
- and
- transmit, to the UE, a second PDSCH transmission comprising one or more blocks, each block of the one or more blocks being transmitted in either the half-duplexing mode or the full-duplexing mode using one or more transmission parameters that are based at least in part on the feedback that indicates the difference between the half-duplex channel quality and the full-duplex channel quality.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a base station, a physical downlink shared channel (PDSCH) transmission comprising one or more blocks, each block of the one or more blocks being transmitted in either a half-duplexing mode or a full-duplexing mode;
- attempting to decode the PDSCH transmission using a low-density parity-check (LDPC) decoder;
- and
- transmitting, to the base station, feedback that indicates a difference between a half-duplex channel quality and a full-duplex channel quality based at least in part on one or more decoding parameters associated with the LDPC decoder.

- and
- transmitting, to the UE, a second PDSCH transmission comprising one or more blocks, each block of the one or more blocks being transmitted in either the half-duplexing mode or the full-duplexing mode using one or more transmission parameters that are based at least in part on the feedback that indicates the difference between the half-duplex channel quality and the full-duplex channel quality.
