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.
Claims20
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a radio resource control (RRC) message that includes an indication to report a plurality of CQI values for a plurality of subbands and further includes, if the indication indicates reporting the plurality of CQI values for the plurality of subbands, a quantization indication that indicates a quantity of bits used to represent a CQI value of a CQI report, the CQI value corresponding to a subband of the plurality of subbands;
- receiving a signal associated with a communication channel;
- and
- transmitting the CQI report comprising the CQI value based at least in part on receiving the signal.
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the UE to:
- receive a radio resource control (RRC) message that includes an indication to report a plurality of CQI values for a plurality of subbands and further includes, if the indication indicates reporting the plurality of CQI values for the plurality of subbands, a quantization indication that indicates a quantity of bits used to represent a CQI value of a CQI report, the CQI value corresponding to a subband of the plurality of subbands;
- receive a signal associated with a communication channel;
- and
- transmit the CQI report comprising the CQI value based at least in part on receiving the signal.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive a radio resource control (RRC) message that includes an indication to report a plurality of CQI values for a plurality of subbands and further includes, if the indication indicates reporting the plurality of CQI values for the plurality of subbands, a quantization indication that indicates a quantity of bits used to represent a CQI value of a CQI report, the CQI value corresponding to a subband of the plurality of subbands;
- receive a signal associated with a communication channel;
- and
- transmit the CQI report comprising the CQI value based at least in part on receiving the signal.
