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 plurality of downlink shared channel transmissions. The UE may transmit, to the base station, a sequence indicating that a hybrid automatic repeat request acknowledgement (ACK) feedback associated with the plurality of downlink shared channel transmissions includes only ACK bits for the plurality of downlink shared channel transmissions. Numerous other aspects are provided.
Claims28
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a network entity, a plurality of downlink shared channel transmissions;
- and
- transmitting, to the network entity and using a first uplink control channel resource that is associated with a first symbol length, a sequence indicating that a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback associated with the plurality of downlink shared channel transmissions includes only ACK bits for the plurality of downlink shared channel transmissions, the sequence including a quantity of bits that is less than a plurality of ACK bits, each ACK bit of the plurality of ACK bits corresponding to a downlink shared channel transmission of the plurality of downlink shared channel transmissions, wherein the first symbol length is less than a second symbol length associated with a second uplink control channel resource carrying the plurality of ACK bits.
A method of wireless communication performed by a network entity, comprising:
- transmitting, to a user equipment (UE), a plurality of downlink shared channel transmissions;
- and
- receiving, from the UE and using a first uplink control channel resource that is associated with a first symbol length, a sequence indicating that a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback associated with the plurality of downlink shared channel transmissions includes only ACK bits for the plurality of downlink shared channel transmissions, the sequence including a quantity of bits that is less than a plurality of ACK bits, each ACK bit of the plurality of ACK bits corresponding to a downlink shared channel transmission of the plurality of downlink shared channel transmissions, wherein the first symbol length is less than a second symbol length associated with a second uplink control channel resource carrying the plurality of ACK bits.
An apparatus for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, wherein the apparatus is configured to:
- receive, from a network entity, a plurality of downlink shared channel transmissions;
- and
- transmit, to the network entity and using a first uplink control channel resource that is associated with a first symbol length, a sequence indicating that a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback associated with the plurality of downlink shared channel transmissions includes only ACK bits for the plurality of downlink shared channel transmissions, the sequence including a quantity of bits that is less than a plurality of ACK bits, each ACK bit of the plurality of ACK bits corresponding to a downlink shared channel transmission of the plurality of downlink shared channel transmissions, wherein the first symbol length is less than a second symbol length associated with a second uplink control channel resource carrying the plurality of ACK bits.
