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.

Abstract: Design of robust radio link monitoring framework for unlicensed spectrum is disclosed. The network may configured two different types of radio link monitoring (RLM) reference signal (RS) resources: default resources, which are transmitted throughout a connection, and additional resources, which may be transmitted only when there has been failure of transmission or reception of the default resources. Various criteria may be used by the network to trigger scheduling transmission of the additional RLM-RS. Moreover, different criteria may prompt a user equipment (UE) to begin monitoring the additional RLM-RS resources, including autonomous and network-initiated criteria.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the UE, a PUR configuration release trigger for the PUR configuration. The method further includes receiving, by the UE, a PUR configuration release message configured to release the PUR configuration. In another aspect, a method of wireless communication includes transmitting, by a network entity, a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the network entity, a PUR configuration release trigger for the PUR configuration. The method further includes transmitting, by the network entity, a PUR configuration release message configured to release the PUR configuration. Other aspects are described and claimed.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a globally unique set of characteristics associated with a cell associated with the base station. The base station may generate a signature value unique to the cell based at least in part on a hash of the globally unique set of characteristics associated with the cell. The base station may transmit a control signal over a channel of a shared radio frequency spectrum band, the control signal comprising a physical cell identifier of the cell and the signature value.

Abstract: Wireless communications systems and methods related to monitoring a paging signal are provided. A wireless communication device may receive a first system information signal from a base station (BS) and may configure a counter with an initial counter value in response to receiving the first system information signal. Additionally, the wireless communication device may receive a second system information signal from the BS and may modify the counter value of the counter in response to receiving the second system information signal. The wireless communication device may monitor for a paging signal from the BS while the counter is outstanding.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a base station (BS) operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify uplink (UL) control information (UCI) to transmit during a subframe. The UE may then select a UL channel on which to transmit the UCI based on whether a shared data and control UL channel employs contention-based scheduling. For example, multiple UEs could contend for access to the same semi-persistently scheduled (SPS) physical UL shared channel (PUSCH). Each UE may utilize a different demodulation reference (DMRS) signal cyclic shift to identify their transmissions. In some cases, some UCI, such as channel state information (CSI), may be transmitted on a contention-based PUSCH, while other UCI, such as acknowledgement information, may be transmitted on a physical uplink control channel (PUCCH). In some cases, the channel selection may be based on a configuration received from a base station.

Abstract: Aspects described herein provide designs to reduce the probability of persistent PF/PO conflicts of different subscriptions for a multi-SIM/USIM UE. A base station may be configured to determine a first conflict avoidance PO based on one or more modified parameters associated with the first conflict avoidance PO. The base station may be further configured to transmit a first paging message in the first conflict avoidance PO in a first DRX cycle. A UE may be configured to receive the one or more modified parameters in SIB. The UE may be configured to determine the first conflict avoidance PO based on the one or more modified parameters. The UE may be further configured to receive the first paging message in the first conflict avoidance PO in the first DRX cycle.
