Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink shared channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink shared channel transmission. Each frequency hop may be determined based on a corresponding uplink shared channel index for a respective repetition a frequency hop for each repetition of the uplink shared channel transmission. The uplink shared channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink shared channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving, in a first time slot, a downlink control information (DCI) message indicating second time slot or first time subslot for transmitting feedback according to a codebook size. The feedback may be transmitted in a physical uplink control channel (PUCCH) associated with a physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH). Corresponding subcarrier spacings (SCSs) for at least two of the PUCCH, the PDSCH, and the PDCCH may be different. The PUCCH may be scheduled as time subslots whereas both the PDSCH and the PDCCH may be scheduled as time slots. Further, the UE may monitor a set of one or more PDCCH monitoring occasions (PMOs) based on a mapping in accordance with a corresponding SCS, the PUCCH being scheduled as time subslots, or both, for feedback transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may separately encode lower priority uplink control information (UCI) and higher priority UCI, and multiplex the encoded lower priority UCI and the encoded higher priority UCI on the same physical uplink channel (e.g., a physical uplink control channel (PUCCH)). The UE may be configured with multiple coding rates, which the UE may select from based on a payload size associated with each of the lower priority UCI and the higher priority UCI. Alternatively, the UE may be configured with a separate set of coding rates for the lower priority UCI and a separate set of coding rates for the higher priority UCI. The UE may multiplex the lower priority UCI and the higher priority UCI by mapping to physical uplink channel resources based on an order (e.g., mapping higher priority UCI followed by mapping lower priority UCI).

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, randomized shifts of a base sequence may be used for transmitting uplink control information. For example, a user equipment (UE) may identify a base sequence of an uplink control message. The UE may also receive signaling that indicates a UE-specific initial shift that may be applied to the base sequence. In some examples, the signaling that indicates the randomized shift may be explicit, implicit, or a combination thereof. After determining one or more shifted sequences based on the UE-specific initial shift, a payload of the uplink control message, and the base sequence, the UE may select a shifted sequence to be transmitted, where the selection is based on a payload of the uplink control message. For example, different shifted sequences may be selected for respective transmissions of scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In some aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: Sub-band full duplexing (SBFD) may allow a user equipment (UE) to both transmit and receive in the same band using an uplink sub-band and one or more downlink sub-bands. Although SBFD may be configured on only some slots, a configuration of a physical uplink channel may be applicable to all symbols. A UE receives a configuration of a physical uplink channel. The configuration is applicable to SBFD symbols and to non-SBFD symbols. The UE receives an indication of resources for transmission on at least a slot configured with the SBFD symbols. The UE determines whether to transmit the physical uplink channel on the resources based on whether all resource blocks of the physical uplink channel are within an uplink sub-band.

Abstract: A UE may receive, from a base station, a first configuration associated with transmitting a low priority UL channel and a second configuration associated with transmitting a high priority UL channel concurrent in time with the low priority UL channel. The UE may cancel the transmission of the low priority UL channel to transmit the high priority UL channel independently, or multiplex the low priority UL channel with the high priority UL channel to transmit both the low priority UL channel and the high priority UL channel together based on a third configuration received from the base station or at least one condition. At least one condition includes a power headroom, a coding rate of high priority data/UCI, or a percentage of resource in high UL channel that is taken by low priority UL transmissions.
