    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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain a signal received over a wireless channel, the signal configuring one or more random access parameters for the wireless channel. The UE may obtain a downlink control signal over the wireless channel, wherein the downlink control signal comprises an indication of a trigger and a location of one or more random access occasions for the UE. The UE may output, based at least in part on the downlink control signal, a random access signal for transmission on the wireless channel during at least one of the one or more random access occasions and according to the one or more random access parameters and the location. The UE may establish a connection with a base station based at least in part on the random access signal.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

    Abstract: Methods, systems, and devices for wireless communications are described that support listen before talk (LBT) for uplink transmissions using multiple subbands. A base station may support communication with a user equipment (UE) via multiple subbands and may transmit an uplink grant to the UE that allocates resources of the multiple subbands for transmission of a shared data channel by the UE. The base station may include an indication within the uplink grant that indicates to the UE to perform a given type of LBT for each subband. After transmitting the uplink grant, the base station may transmit control information or other signaling (e.g., channel occupancy time system information (COT-SI)) that indicates subbands on which the UE is to perform a given type of LBT or other subbands on which the UE is to perform a different type of LBT.
