Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine updated system information for a user equipment (UE), wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP; and transmit the updated system information to the UE using at least one of unicast signaling, multicast signaling, the configured BWP, or a particular BWP that is different from the configured BWP. Numerous other aspects are provided.

Abstract: Configured grant (CG) channel occupancy time (COT) sharing procedure is disclosed. A user equipment (UE) sharing a COT may indicate in the uplink control indicator (UCI) the remaining COT duration, an offset indication identifying where the uplink transmission is expected to end, and a channel access priority class (CAPC) which may be used by the base station to determine which type of data may be included in downlink transmissions in the shared COT. Where the energy detection (ED) threshold has not been configured for COT sharing, the UE may reduce the information included in the UCI. The base station may alternatively configured which information for the UE to include in the UCI for potential COT sharing. The COT sharing information may further be compressed by coding such information into tables or leveraging knowledge of transmission characteristics, such as configured end points.

Abstract: In one aspect, an apparatus of wireless communication at a user equipment includes receiving, during a radio resource control (RRC) setup, a sounding reference signal (SRS) resource set configuration including a specified time offset x. The UE may receive downlink control information (DCI) in a later time slot and an instruction to trigger the SRS resource set. The UE determines, based on information from the SRS configuration or the DCI, a starting position within a time slot for transmitting an SRS resource. The UE transmits, at the starting position x slots after the later time slot, a reference SRS resource selected from the SRS resource set, followed sequentially by the remaining resources. In another aspect a UE that receives a t value of multiple t values may transmit the reference resource in a (t+1)th time slot from a reference slot.

Abstract: Wireless communications systems and methods related to transmission of discovery signals are provided. A wireless communication device communicates an indication of an uplink (UL) resource that falls within a discovery reference signal (DRS) measurement timing configuration (DMTC) window. The wireless communication device communicates an UL transmission within the UL resource during the DMTC window.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration for a reference signal comprising a single carrier waveform and associated with single carrier signals for a plurality of symbol periods, the configuration indicating a plurality of channels associated with the reference signal and a set of functions associated with the reference signal. The UE may receive, according to the configuration, the reference signal in a first one or more symbol periods of the plurality of symbol periods and the single carrier signals on the plurality of channels in a second one or more symbol periods of the plurality of symbol periods. The UE may perform the set of functions on the received single carrier signals based at least in part on the received reference signal.

Abstract: In embodiment methods for managing uplink spatial filter configuration, comprising, a processor of a wireless device may send an initial access signal using two or more spatial filters, wherein each spatial filter directs a beam to a respective uplink (UL) receive (Rx) point, receive from the base station an indication of which beam to use for UL transmissions, and send to the base station another signal using the spatial filter corresponding to the indicated beam. A base station may receive the initial access signal via two or more UL Rx points on two or more beams, determine which of the two or more beams provides a better received signal, send an indication of the better of the two or more beams to the wireless device, and receive from the wireless device another signal on the indicated better of the two or more beams via a corresponding UL Rx point.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.

Abstract: Methods, systems, and devices for wireless communication are described that may enable a user equipment (UE) to monitor a shared spectrum to receive control signaling and data transmissions associated with different transmission time intervals (TTIs). For example, a base station may communicate with a UE according to a first transmission mode during a first, shortened TTI. The base station may transmit a downlink control channel for a shortened TTI based on a subset of a number of blind decodes or control channel elements. Additionally, a downlink control channel for a shortened TTI may contain grants for multiple TTIs. In some cases, the base station may transmit a signaling to the UE via a reference signal, downlink control channel, or radio resource control which may indicate a change from the shortened-TTI transmission mode to a transmission mode with a TTI duration that is longer than the first, shortened TTI duration.

Abstract: Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-COT resources. The UE may then transmit to a second UE using the set of transmission resources.
