Strategies for deferring semi-persistent scheduling uplink control channel transmissions

A method for wireless communication at a network entity, comprising:

• transmitting, to a user equipment (UE), a first set of downlink transmissions in accordance with a first semi-persistent scheduling configuration and a second set of downlink transmissions in accordance with a second semi-persistent scheduling configuration, the first semi-persistent scheduling configuration different from the second semi-persistent scheduling configuration, the first set of downlink transmissions associated with a first set of feedback bits and the second set of downlink transmissions associated with a second set of feedback bits, both the first set of feedback bits and the second set of feedback bits scheduled for transmission to the network entity in a first set of uplink symbols;
• identifying that only a subset of the first set of uplink symbols is available for transmission of the first set of feedback bits and the second set of feedback bits;
• determining that the UE is to defer transmission of one of the first set of feedback bits or the second set of feedback bits or both of the first set of feedback bits and the second set of feedback bits to a second set of uplink symbols based at least in part on the identifying and on a deferment scheme;
• and
• monitoring for the first set of feedback bits and the second set of feedback bits in accordance with the deferment scheme.

An apparatus for wireless communication at a user equipment (UE), comprising:

• at least one processor;
• and
• memory coupled with the at least one processor, the memory storing instructions executable by the at least one processor to cause the UE to:
• generate a first set of feedback bits associated with a first set of downlink transmissions of a first semi-persistent scheduling configuration and a second set of feedback bits associated with a second set of downlink transmissions of a second semi-persistent scheduling configuration, the first semi-persistent scheduling configuration different from the second semi-persistent scheduling configuration, both the first set of feedback bits and the second set of feedback bits scheduled for transmission to a network entity in a first set of uplink symbols;
• identify that only a subset of the first set of uplink symbols is available for transmission of the first set of feedback bits and the second set of feedback bits;
• determine to defer transmission of one of the first set of feedback bits or the second set of feedback bits or both of the first set of feedback bits and the second set of feedback bits to a second set of uplink symbols based at least in part on the identifying and on a deferment scheme;
• and
• transmit the first set of feedback bits and the second set of feedback bits to the network entity in accordance with the deferment scheme.
