Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive a beam switch command for a first link between the receiver and a transmitter, wherein the beam switch command is received via a second link between the receiver and the transmitter. The receiver may transmit an acknowledgement (ACK) corresponding to the beam switch command, wherein the ACK is transmitted via the second link. The receiver may perform a beam switch procedure on the first link based at least in part on transmitting the ACK via the second link. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a receiver, comprising:
- receiving a beam switch command for a first link between the receiver and a transmitter via a second link between the receiver and the transmitter, wherein the first link and the second link use different frequency bands;
- transmitting an acknowledgement (ACK) corresponding to the beam switch command via the second link;
- and
- performing a beam switch procedure on the first link based at least in part on transmitting the ACK via the second link.
A method of wireless communication performed by a receiver, comprising:
- receiving downlink control information (DCI) that indicates one or more resources for transmission of acknowledgement or negative acknowledgement (ACK/NACK) feedback corresponding to a beam switch command for a first link between the receiver and a transmitter, wherein the DCI is received via a second link between the receiver and the transmitter that uses a different frequency band than the first link;
- receiving the beam switch command;
- and
- transmitting the ACK/NACK feedback, corresponding to the beam switch command, using the one or more resources indicated in the DCI received via the second link.
A method of wireless communication performed by a receiver, comprising:
- receiving a beam switch command from a transmitter, wherein the beam switch command includes at least one of:
- a first indication to switch from a first downlink beam pair to a second downlink beam pair,
- a second indication to switch from a first uplink beam pair to a second uplink beam pair,
- a third indication of a sequence of beam switches to be performed over a time period, or
- a fourth indication to switch beam pairs for a point of a coordinated multipoint communication;
- and
- performing a beam switch procedure based at least in part on the beam switch command.
A method of wireless communication performed by a receiver, comprising:
- receiving, from a transmitter, a beam switch command to switch away from a first beam pair, wherein the beam switch command identifies a second beam pair;
- determining that the second beam pair is not to be used;
- and
- performing a beam switch procedure to switch from the first beam pair to a third beam pair based at least in part on determining that the second beam pair is not to be used.
