Abstract: This disclosure provides systems, methods, and devices for wireless communication that support sub-slot based Type-1 hybrid automatic repeat request (HARQ) feedback codebook generation. In aspects, techniques are provided for generating a set of candidate physical downlink shared channel (PDSCH) reception occasions for an active bandwidth part (BWP) of a downlink (DL) serving cell. In aspects, a user equipment (UE) obtains a set of UL sub-slots based, at least in part, on a set of K1 values, and then determines, for each UL sub-slot in the set of UL sub-slots, whether the UL sub-slots satisfy a predetermined overlapping condition with a current DL slot. A PDSCH reception occasions set is generated based, at least in part, on a set of time domain resource allocation (TDRA) candidates of the current DL slot and a determination that a current UL sub-slot satisfies the predetermined overlapping condition with the current DL slot.

Abstract: Aspects relate to wireless communication having sounding reference signal (SRS) power control using non-scheduling downlink control information (DCI) that is configured to trigger aperiodic SRS without scheduling data and without a channel state information (CSI) request. The non-scheduling is configured to include at least two transmit power control (TPC) commands. A first TPC command is configured for power control of a physical uplink shared channel (PUSCH) transmitted by a UE to a base station. A second TPC command is configured for power control of one or more sounding reference signal (SRS) resource sets. Additionally, the first TPC command may be independent from the second TPC command where different power control is implemented for the PUSCH and the SRS transmissions. Additionally, the non-scheduling DCI may be formatted according to a DCI format 0_1 or a DCI format 0_2.

In some aspects, a user equipment (UE) may receive an indication of a plurality of sets of contiguous time domain resources corresponding to a plurality of segments of a multi-slot transmission occasion. The UE may identify an interruption of a multi-slot communication associated with an impacted segment of the plurality of segments. The UE may transmit at least one communication on the multi-slot transmission occasion based on at least one of: prioritization on the impacted segment, a bandwidth part switch associated with the interruption, one or more segments, of the plurality of segments, that occur after the impacted segment, or a remainder of the impacted segment. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a first source UE of two or more source UEs, an indication of a first resource allocation for transmitting first data. The UE may transmit, to a second source UE of the two or more source UEs, an indication of a second resource allocation for transmitting second data. The UE may receive, from the first source UE, the first data using the first resource allocation. The UE may receive, from the second source UE, the second data using the second resource allocation. The UE may transmit the first data and the second data to at least one destination UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols indicated by the configuration. The UE may determine a quantity of resource blocks for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols. The UE may transmit, to a base station, the repetition on the second quantity of symbols using the quantity of resource blocks for each repetition with the first quantity of symbols.

Abstract: Certain aspects of the present disclosure provide techniques for skipping or using actual repetitions. A method that may be performed by a user equipment (UE) includes receiving, from a base station, a configuration indicating resources for a first repetition and a second repetition in a physical uplink control channel (PUCCH). In certain aspects, the method may also include transmitting the first repetition, wherein the first repetition includes a larger symbol length than the second repetition, the resources for the first repetition multiplex a plurality of transmissions from first UEs including the UE, the resources for the second repetition multiplex a plurality of transmissions from second UEs, and a quantity of the first UEs is larger than a quantity of the second UEs.

Abstract: A base station (BS) may determine (estimate) a preparation time for at least one uplink (UL) transmission by a user equipment (UE) on at least one radio frequency (RF) carrier. The BS may use the preparation time to ensure that the BS sends a grant for the at least one transmission to the UE a sufficient amount of time before the at least one transmission is scheduled to occur to give the UE sufficient time to conduct the at least one UL transmission. In some examples, the BS determines the preparation time based on adjusting an uplink preparation time according to a defined value. In some examples, the BS determines the preparation time based on a subcarrier spacing (SCS) index. The BS may select the SCS index used to determine the preparation time from smallest of the SCS indexes configured for the different RF carriers.
