Abstract: Techniques described herein include solutions for enabling NR sidelink (SL) communications by using radio resource control (RRC) to provide ser equipment (UEs) with grant configuration (CGs) for unidirectional and/or bidirectional SL communications. These techniques also include solutions for UEs to obtain channel occupation times (COTs) for SL communications, and procedures for sharing COTs with other UEs, and procedures for CG uplink control information (UCI) of physical uplink shared channels (PUSCH) transmissions for NR in the unlicensed spectrum (NR-U). The techniques described herein also include solutions for channel state information (CSI) feedback for CGs of SL in the unlicensed spectrum (CG-Sidelink-U). Also described herein are SL techniques for transmission power control of SL communications and clear channel assessment (CCA) procedures.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: Apparatuses, systems, and methods for providing downlink control for non coherent joint transmission. A cellular base station may provide downlink control information associated with a non coherent joint transmission downlink data communication to a wireless device, which may receive the downlink control information. The downlink control information may be provided as a single downlink control information including scheduling information for two data streams of the non coherent joint transmission data communication, or a portion of a multi-stage downlink control information transmission. The wireless device may receive the non coherent joint transmission downlink data communication based at least in part on the downlink control information.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method indicates a frequency resource reservation in sidelink control information (SCI). The method includes identifying a transport block (TB) for transmission to a UE; determining a total number of sub-channels (NSL) in a resource pool for sidelink communication, a number of sub-channels (Lsub) of the TB, a first starting sub-channel index x1 of a first retransmission of the TB, and a second starting sub-channel index x2 of a second retransmission of the TB. The method includes determining a frequency resource indication value (FRIV) based on NSL, LSUB, x1, and x2, wherein the FRIV represents a result of a predetermined function of Lsub, x1, and x2 that generates a unique value for possible combinations of Lsub, x1, and x2. The FRIV is encoded in SCI and the SCI is transmitted to the UE.

Abstract: A method and apparatus for a wireless device of reduced capabilities to access a wireless communication network targeted to operate with wireless device having higher capabilities is disclosed. The device may receive from abase station of the wireless communication network an indication of whether the type of devices that includes the wireless device of reduced capabilities is allowed to access the wireless communication network. The device may transmit to the base station signaling associated with connecting to the base station if the base station indicates that the type of devices with reduced capabilities is allowed to access the wireless communication network. The signaling allows the device to connect to the base station. The device may transmit capability information of the device to the base station. The device may configure its features based on the capability information to communicate with the base station.

Abstract: A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Abstract: This disclosure relates to techniques for periodic reference signal activation and deactivation in a wireless communication system. Information configuring periodic reference signals may be received by a wireless device. Information deactivating some or all of the periodic reference signals may be received by the wireless device. The information deactivating some or all of the periodic reference signals may be received using different signaling type than the information configuring the periodic reference signals.

Abstract: A user equipment device may determine whether to power down one or more components based at least on a scheduling parameter that includes an indication of cross-slot scheduling. The device may power down the one or more components prior to decoding control information during a slot for which the scheduling parameter indicates that cross-slot scheduling is in place.
