Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- determining to transmit uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU),
- wherein the PUSCH communication includes a payload of a msgA communication in a contention-free two-step RACH procedure;
- transmitting the UCI in the PRU based at least in part on determining to transmit the UCI;
- and
- receiving an indication of the PRU in at least one of a compact downlink control information (DCI) communication or a group-common DCI communication.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled with the memory, the one or more processors configured to:
- determine to transmit uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU) based at least in part on determining that a plurality of PRUs, included in a PRU group in which the PRU is included, are mapped to a shared set of time-domain resources and frequency-domain resources;
- and
- transmit the UCI in the PRU based at least in part on determining to transmit the UCI.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
- determine to transmit uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU) based at least in part on determining that a plurality of PRUs, included in a PRU group in which the PRU is included, are nested in a time domain and a frequency domain such that the plurality of PRUs share a same starting time-domain resource and a same starting frequency-domain resource;
- and
- transmit the UCI in the PRU based at least in part on determining to transmit the UCI.
An apparatus for wireless communication, comprising:
- means for determining to transmit uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU) based at least in part on determining that a plurality of PRUs, included in a PRU group in which the PRU is included, are nested in a time domain and a frequency domain such that the plurality of PRUs share a same starting time-domain resource and a same starting frequency-domain resource;
- and
- means for transmitting the UCI in the PRU based at least in part on determining to transmit the UCI.
