    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support cross-slot scheduling of sidelink transmissions in a wireless communication system. A transmitting user equipment (UE) in communication with a receiving UE over a sidelink transmits cross-slot schedule information to the receiving UE at a time prior to a first slot over which a physical sidelink shared channel (PSSCH) transmission is to be transmitted to the receiving UE. The cross-slot schedule information includes information that is sufficient to decode the PSSCH transmission received by the receiving UE at the first slot, without requiring the receiving UE to decode a physical sidelink control channel (PSCCH) transmission including a sidelink control information (SCI) message received during the first slot. In aspects, the PSSCH transmission may be decoded in parallel with the PSCCH transmission received in the first slot.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication that includes one or more codepoints indicating a plurality of transmit precoder matrix indicator (TPMI) indices and/or a sounding reference signal (SRS) resource indicator (SRI) codepoint indicating one or more SRS resources. The UE may identify, based at least in part on the one or more codepoints, one or more TPMI indices, of the plurality of TPMI indices, for one or more repetitions of a codebook-based PUSCH transmission and/or may identify, based at least in part on the SRI codepoint, one or more SRS resources for the one or more repetitions. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a gap period following a downlink portion of a time division duplexing (TDD) frame. The UE may selectively perform, based at least in part on the gap period, a clear channel assessment (CCA) on a channel of a radio frequency spectrum band. The UE may transmit at least one of a sounding reference signal (SRS) or a physical random access channel (PRACH) preamble in a set of initial symbols of an uplink portion of the TDD frame following the gap period, wherein the SRS or PRACH preamble is frequency-domain multiplexed during the set of initial symbols with one or more of: a demodulation reference signal (DMRS), an uplink data transmission, an uplink control transmission, or a random access transmission.

    Abstract: This disclosure provides methods, devices, and systems supporting power control parameter configuration for configured grants (CGs). In some implementations, a user equipment (UE) may receive control signaling configuring multiple sounding reference signal (SRS) resource sets and multiple sets of power control parameters for CG uplink transmission. The UE may receive downlink control information (DCI) scheduling a retransmission and indicating which set of power control parameters the UE is to use for the CG uplink retransmission. In some other implementations, the control signaling may configure multiple SRS resources sets but a single set of power control parameters. The UE may receive DCI activating the CG configuration or scheduling a retransmission, the DCI indicating a second set of power control parameters not configured by the control signaling. The UE may automatically use the power control parameters configured by the control signaling or may determine a second set based on the DCI.

    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive, from a network device, a downlink control message that schedules a first and second repetition of a transport block for a downlink shared channel in a first component carrier of multiple component carriers, the first and second repetitions scheduled in a first and second transmission occasion associated with the downlink shared channel. The UE may monitor for the repetitions in the respective transmission occasions, and the UE may decode the transport block based on a number of transmission occasions associated with the downlink shared channel in the component carrier and a data rate limit across the multiple component carriers including the first component carrier.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating an aggregated sidelink resource reservation rule for reserving time-contiguous transmission time intervals. The UE may transmit a sidelink control reservation message based on the aggregated sidelink resource reservation rule. The sidelink control reservation message may indicate a starting transmission time interval for reserving a set of time-contiguous transmission time intervals in a sidelink shared channel. Additionally or alternatively, the sidelink control reservation message may indicate a quantity of the set of time-contiguous transmission time intervals reserved for transmission of a set of aggregated sidelink messages. The UE may transmit the set of aggregated sidelink messages via the set of time-contiguous transmission time intervals of the sidelink shared channel indicated in the sidelink control reservation message.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some implementations, a base station (BS) may transmit downlink (DL) data using a sequence of DL hopping frames on a corresponding sequence of unique hopping channels associated with a DL frequency hopping pattern. In some implementations, each user equipment (UE) of one or more UEs may transmit uplink (UL) data using a sequence of UL hopping frames on a corresponding sequence of unique hopping channels associated with a different UL frequency hopping pattern.
