Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a measurement report indicating a set of channel quality indicators for a set of candidate beams; determine that a downlink transmission from a base station is not received via one or more beams of the set of candidate beams; and transmit a negative acknowledgement for the downlink transmission via one or more new beams of the set of candidate beams. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit a measurement report indicating a set of channel quality indicators for a set of candidate beams;
- determine that a downlink transmission, transmitted from a base station via one or more beams of the set of candidate beams, is not received;
- and
- transmit a negative acknowledgement for the downlink transmission, via one or more new beams of the set of candidate beams, without receiving an indication to transmit the negative acknowledgement for the downlink transmission via the one or more new beams after determining that the downlink transmission via the one or more beams is not received.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting a measurement report indicating a set of channel quality indicators for a set of candidate beams;
- determining that a downlink transmission, transmitted from a base station via one or more beams of the set of candidate beams, is not received;
- and
- transmitting a negative acknowledgement for the downlink transmission, via one or more new beams of the set of candidate beams, without receiving an indication to transmit the negative acknowledgement for the downlink transmission via the one or more new beams after determining that the downlink transmission via the one or more beams is not received.
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:
- transmit a measurement report indicating a set of channel quality indicators for a set of candidate beams;
- determine that a downlink transmission, transmitted from a base station via one or more beams of the set of candidate beams, is not received;
- and
- transmit a negative acknowledgement for the downlink transmission, via one or more new beams of the set of candidate beams, without receiving an indication to transmit the negative acknowledgement for the downlink transmission via the one or more new beams after determining that the downlink transmission via the one or more beams is not received.
An apparatus for wireless communication, comprising:
- means for transmitting a measurement report indicating a set of channel quality indicators for a set of candidate beams;
- means for determining that a downlink transmission, transmitted from a base station via one or more beams of the set of candidate beams, is not received;
- and
- means for transmitting a negative acknowledgement for the downlink transmission, via one or more new beams of the set of candidate beams, without receiving an indication to transmit the negative acknowledgement for the downlink transmission via the one or more new beams after determining that the downlink transmission via the one or more beams is not received.
