Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: Systems and methods for measuring at and reporting by a target user equipment (UE) of one or more positioning signals sent from one or more assisting UEs to the target UE are disclosed herein. The target UE may receive a positioning signal from an assisting UE according to a communication received at the target UE. The target UE may proceed to perform a positioning measurement using the positioning signal received from the target UE. The positioning measurement may be used by the target UE to estimate its own position, or the positioning measurement may be sent to another entity within a wireless communications system to be used in estimating the physical position of the UE. The handling of multiple received positioning signals from various sources, and the handling of situations where, for example, a transmission reception point (TRP) and an assisting UE may schedule overlapping positioning signals, ate also discussed.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method includes receiving, via frequency and time resources of a physical sidelink shared channel (PSSCH), from a second UE, a signal encoding a sequence of bits corresponding to sidelink control information (SCI) stage 2; decoding the sequence of bits based on a SCI stage 2 scrambling initialization value (Cinit) to generate SCI stage 2 for a transport block (TB), wherein Cinit is determined based on at least a portion of a physical sidelink control channel (PSCCH) cyclic redundancy check (CRC) code; and receiving the TB from the first UE based on the SCI stage 2.

Abstract: This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE reports, to a base station, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, receives, from the base station, a reduced monitoring capability (MO) configuration, wherein the base station determines the reduced MO configuration based on the reported reduced PDCCH monitoring capability and monitors the PDCCH based on the reduced MO configuration.

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: The exemplary embodiments relate to signaling between a user equipment (UE) and a cell over the unlicensed spectrum. The UE may receive a signal broadcast by a cell of the network over a channel in the unlicensed spectrum. The signal includes a set of channel state information reference signals (CSI-RS) each corresponding to a set of synchronization signal blocks (SSB) and is transmitted during a discovery reference signal (DRS) window. The UE may then determine a location of the set of CSI-RS within the DRS window and perform an operation based on the set of CSI-RS.

Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.
