Handling collisions between uplink data repetitions and an uplink control transmission
This disclosure describes methods, devices, and systems for techniques related to wireless communications, and more particularly uplink transmissions on one or more of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH). Generally, the described techniques support handling collisions between PUSCH repetitions and a PUCCH transmission. A user equipment (UE) may identify that uplink control information (UCI) is scheduled for transmission via an uplink control transmission that overlaps with multiple repetitions of an uplink data transmission. The UE may determine, for each of the multiple repetitions, a quantity of resources available for carrying multiplexed uplink control information, generate encoded UCI by encoding the UCI based on the quantity of resources available in each of the multiple repetitions, and multiplex the encoded UCI on at least a portion of the multiple repetitions based on the quantity of resources available in each of the multiple repetitions.
1. A method for wireless communication at a user equipment (UE), comprising:
multiplexing uplink control information on one or more selected repetitions of multiple scheduled repetitions of an uplink data transmission, the uplink control information being scheduled overlapping the multiple scheduled repetitions, the one or more selected repetitions being a portion of the multiple scheduled repetitions, the one or more selected repetitions being determined to be multiplexed based on a capacity of the one or more selected repetitions; and
transmitting the uplink control information based on multiplexing the uplink control information on the one or more selected repetitions.
2. The method of claim 1 , the one or more selected repetitions is one selected repetition.
3. The method of claim 2 , the one or more selected repetitions being further based on being first in time.
4. The method of claim 3 , the one or more selected repetitions being determined to be multiplexed based on a number of symbols of the one or more selected repetitions and a threshold associated with the number of symbols.
5. The method of claim 4 , further comprising:
generating encoded uplink control information by encoding the uplink control information;
wherein multiplexing uplink control information on one or more selected repetitions comprising multiplexing the encoded uplink control information on the one or more selected repetitions.
6. An apparatus for wireless communication, comprising:
a processor,
memory in electronic communication with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
multiplex uplink control information on one or more selected repetitions of multiple scheduled repetitions of an uplink data transmission, the uplink control information being scheduled overlapping the multiple scheduled repetitions, the one or more selected repetitions being a portion of the multiple scheduled repetitions, the one or more selected repetitions being determined to be multiplexed based on a capacity of the one or more selected repetitions; and
transmit the uplink control information based on the uplink control information being multiplexed on the one or more selected repetitions.
7. An apparatus for wireless communication, comprising:
a processor,
memory in electronic communication with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
multiplex uplink control information on one or more selected repetitions of multiple scheduled repetitions of an uplink data transmission, based on a capacity of the one or more selected repetitions,
the one or more selected repetitions is one selected repetition,
the one or more selected repetitions being further based on being first in time,
the one or more selected repetitions being based on a number of symbols of the one or more selected repetitions and a threshold associated with the number of symbols,
the uplink control information being scheduled for transmission by the UE via an uplink control transmission,
the uplink control transmission overlapping with at least one of the multiple scheduled repetitions of the uplink data transmission; and
transmitting the uplink control information.
