Abstract: Wireless communications systems and methods related to communications in a network are provided. A user equipment (UE) may generate during a first time period, an uplink (UL) communication signal based on a scheduled grant or a configured UL grant. The UE may detect a downlink (DL) communication from a base station (BS) during a second time period after the first time period. The DL communication is devoid of the scheduled grant and the configured UL grant. The UE may transmit to the BS, the UL communication signal based on the scheduled grant or the configured UL grant in response to detecting the DL communication.

Abstract: Techniques and devices for wireless communications are described that provide for staggering sounding reference signal (SRS) transmissions in frequency across multiple orthogonal frequency division multiplexing (OFDM) symbols, which may allow multiple UEs to transmit SRS using a common listen-before-talk (LBT) gap for a LBT procedure. The techniques also provide for transmitting an SRS across multiple OFDM symbols using same frequency resources, and an orthogonal cover code (OCC) may be applied to the SRS transmission of each OFDM symbol, which may allow multiple UEs to transmit concurrent SRS using a common LBT gap.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for group reference signal triggering for contention-based systems. The described techniques may enable a network node to trigger a group of one or more user equipments (UEs) to transmit a reference signal to the network node. The network node may transmit a group common control channel indicating timing information or configuration information corresponding to a set of resources for the transmission of the reference signal. The one or more UEs may transmit the reference signal according to the timing information or configuration information.

Abstract: Methods, systems, and devices for wireless communications are described for managing sounding reference signal (SRS) transmissions in shared radio frequency spectrum. Described techniques provide for increased occasions at which a SRS may be transmitted, enhance likelihood of a successful listen-before-talk (LBT) procedure, or any combinations thereof. Increased occasions for SRS may be provided through multiple transmission times that are available in the event of an earlier LBT failure. Enhanced likelihood of successful LBT may be provided through one or more timing offsets that may be randomly selected from a set of available timing offsets, selection of a cyclic prefix length for a SRS based on whether the SRS transmission is within or outside of a channel occupancy time of a base station, providing an initial SRS transmission time for an initial periodic time interval, triggering of an aperiodic SRS within the channel occupancy time, or any combinations thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a control channel resource configuration associated with an unlicensed spectrum, wherein the control channel resource configuration is associated with an indication of whether a resource to be used for an uplink control channel in the unlicensed spectrum is a fixed resource, a floating resource, or an adaptive resource. The UE may identify the resource based at least in part on the control channel resource configuration. The UE may transmit uplink control information on the identified resource. Numerous other aspects are provided.

Abstract: Enhanced transmission opportunities are disclosed for sounding reference signals (SRS). The enhancements may provide more flexibility in scheduling SRS transmission and more SRS transmission opportunities. An additional offset may be defined and dynamically communicated to a user equipment (UE) to use either to override or in additional to a semi-statically communicated standard offset when scheduling the SRS transmission opportunity based on an SRS trigger slot or another granted slot. The UE may further treat each combination of timing information as a separate SRS opportunity or may define a window between two signaled timing offsets within which the UE may attempt SRS transmissions.

Abstract: Hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback enhancements are disclosed for new radio (NR) unlicensed (NR-U). In the downlink control channel, two sets of identifiers (IDs) may be explicitly or implicitly signaled. The two IDs identify a current set ID and an additional set ID. Where the two IDs match, then the ACK feedback transmitted in the current ACK message will reflect the current transmissions. Otherwise, where the two IDs are different, the additional set ID identifies any previous or different ACK information that should be transmitted for prior transmissions.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. In some aspects, a user equipment (UE) may enable adaptive receive diversity (RxD) by receiving an indicator for a channel occupancy time (COT), outside of the COT and in a non-RxD mode, and may transfer to the RxD mode for reception during the COT. After an end to the COT, the UE may return to the non-RxD mode. In this way, the UE enables improved power gain, diversity gain, or spatial nulling gain during a COT, and enables reduced power utilization outside of the COT.
