Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal associated with a communication channel. The UE may transmit a channel quality indicator (CQI) report comprising one or more CQI values based at least in part on a determined number of bits used to represent the one or more CQI values. The number of bits used to represent the one or more CQI values is based at least in part on a number of the one or more subbands. Numerous other aspects are described.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a control message that includes a quantization indication that indicates a number of bits used to represent one or more channel quality indicator (CQI) values corresponding to one or more subbands to be reported in a CQI report, wherein the number of bits used to represent each of the one or more CQI values is based at least in part on a number of the one or more subbands to be reported in the CQI report;
- receiving a signal associated with a communication channel;
- and
- transmitting the CQI report comprising the one or more CQI values based at least in part on the quantization indication.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a signal associated with a communication channel;
- determining a number of bits used to represent one or more channel quality indicator (CQI) values corresponding to one or more subbands to be reported in a CQI report, wherein the number of bits used to represent each of the one or more CQI values is based at least in part on a number of the one or more subbands to be reported in the CQI report;
- and
- transmitting the CQI report comprising the one or more CQI values based at least in part on the determined number of bits.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a control message that includes a quantization indication that indicates a number of bits used to represent one or more channel quality indicator (CQI) values corresponding one or more subbands to be reported in a CQI report, wherein the number of bits used to represent each of the one or more CQI values is based at least in part on a number of the one or more subbands to be reported in the CQI report;
- receive a signal associated with a communication channel;
- and
- transmit the CQI report comprising the one or more CQI values based at least in part on the quantization indication.
