Abstract: Wireless communication devices, systems, and methods related to downlink control information (DCI) monitoring and semi-persistent scheduling (SPS) reception for limited capability devices are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from the base station, a semi-persistent scheduling (SPS) grant, the SPS grant indicating a periodicity; monitoring, in a slot scheduled for a downlink data communication, for an SPS release and the downlink data communication; and transmitting, to the base station, an acknowledgement (ACK) or negative acknowledgment (NACK) based on the monitoring.

Abstract: Systems and methods for scheduling uplink transmissions are disclosed. In an aspect, a user equipment (UE) receives a downlink control information signal, wherein the downlink control information indicates an uplink grant for multiple contiguous nominal uplink repetitions, identifies resources allocated for the multiple contiguous nominal uplink repetitions based on the uplink grant, wherein the identified resources include first resources for a first actual repetition of uplink data and second resources for a second actual repetition of uplink data, transmits the first actual repetition of uplink data using the first resources, and transmits the second actual repetition of the uplink data using the second resources.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a base station has scheduled the UE for one or more downlink transmissions, each of the one or more downlink transmissions having an associated repetition factor that corresponds to one of a plurality of configured repetition factors configured at the UE. The UE may identify an applied repetition factor to apply to feedback codebook generation for the one or more downlink transmissions. The UE may generate a feedback codebook for reporting feedback for the one or more downlink transmissions, the feedback codebook populated based at least in part on the applied repetition factor and on whether the one or more downlink transmissions were successfully received and decoded. The UE may transmit to the base station a feedback report that includes the feedback codebook.

Abstract: Various procedures associated with autonomous uplink (AUL) are disclosed. In order to address the mismatch between listen before talk (LBT) and AUL bandwidth a fractional sensing channel is defined less than 20 MHz. Accordingly, a user equipment (UE) may use the fractional sensing channel to perform LBT only on the resources allocated for AUL. Contention window update may further be modified for transmissions spanning multiple transmission opportunities (TxOPs). A contention window update may occur over all transmission channels considering full acknowledgement information of each TxOP, a percentage of acknowledgement information weighted on the number of channels, a percentage of acknowledgement information weighted on the ratio of resources on each channel, or by selecting a primary channel of the multiple channels for the contention window update. In repetition scenarios, the reference transmission for contention window updates may be selected depending on whether all repetitions are within one or multiple TxOPs.

Abstract: In an aspect, a UE determines whether there is an overlap between a first uplink transmission channel allocated for transmission of a first uplink transmission and a second uplink transmission channel allocated for transmission of second uplink transmission. The UE generates a combined uplink transmission payload in response to a determination that there is the overlap, wherein the combined uplink transmission payload includes at least a portion of the first uplink transmission and at least a portion of the second uplink transmission. The UE transmits the combined uplink transmission payload on either the first uplink transmission channel or the second uplink transmission channel. A base station receives the combined uplink transmission payload transmitted by the UE.

Abstract: Some aspects of the present disclosure disclose methods and systems related to separate and joints releases of semi-persistent scheduling (SPS) configured transmission occasions by an SPS release. For example, a user equipment (UE) may receive, from a base station (BS) and via a physical downlink control channel (PDCCH), a semi-persistent scheduling (SPS) release configured to jointly release at the UE a plurality of SPS configurations, each SPS configuration of the plurality of SPS configurations configured to schedule one or more SPS physical downlink shared channel (PDSCH) transmission occasions of a plurality of SPS PDSCH transmission occasions. In some instances, the plurality of SPS PDSCH transmission occasions may occur in a same slot as the SPS release. Further, the UE may not expect to receive, or refrain from receiving, SPS PDSCH via the plurality of SPS PDSCH transmission occasions.

Abstract: A method of wireless communications by a transmitting sidelink user equipment (UE) includes transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB). The SL-SS has an SL-SS pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols, which may be zero PSBCH symbols. The method also includes receiving transmission in accordance with the SL-SS. The SL-SS may be transmitted at a time and/or frequency different from a legacy SL-SS.
