Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

Abstract: An apparatus of a Fifth Generation NodeB (gNB) to operate in a License Assisted Access (LAA) system configures a transmission initiation time interval contention window size (CWS) of N number of subframes between Category 4 Listen Before Talk (LBT) uplink (UL) transmissions by a user equipment (UE) operating in the LAA system, and a memory to store a value of N which can have a value 6 or greater or 10 or greater. An apparatus of a UE to operate in an LAA system decodes a configuration from the gNB of a transmission initiation time interval contention CWS of N number of subframes between Category 4 LBT UL transmissions in the LAA system. The CWS is increased to a next higher value when an UL grant or an autonomous UL (AUL) downlink feedback indicator (DFI) is not received before the expiration of a timer.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Abstract: In an example method, a user equipment (UE) device receives a slot of data from a base station (BS). The UE device determines a quality of a wireless channel between the BS to the UE device, including determining (i) a metric for a interval extending from a sequentially first symbol of the slot of data to a symbol immediately preceding the first subset of symbols, (ii) a metric for an interval extending from the sequentially first symbol of the slot of data to a sequentially last symbol of the first subset of symbols, (iii) a metric for an interval extending from the sequentially first symbol of the slot of data to a symbol immediately preceding the second subset of symbols, and/or (iv) a metric for an interval extending from the sequentially first symbol of the slot of data to a sequentially last symbol of the second subset of symbols.

Abstract: A first transmission power level based on a radio frequency exposure limit and a second transmission power level based on the first transmission power level and a probability of detection of a body by a body proximity sensor are determined, where it is ensured that an average usage of the first and second transmission power levels over time does not exceed the transmission power limit, determined based on radio frequency exposure limits. A transmission power gain is determined based on a difference between the first and second transmission power level based on the probability of detection, and a false alarm rate of the body by the body proximity sensor. The transmission power gain may be used as a performance indicator to select from multiple first and second transmission power gains. First and second transmission power gains corresponding to the selected transmission power gain may be stored and applied during transmission.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform cell reselection. In an example, timing requirements for synchronization signal processing are defined based on a beam sweeping capability of the device. Synchronization signals are received and processed according to the timing requirements to complete a cell reselection procedure. In another example, location data of the device is used to look up a database of cell identifiers. A cell identifier is determined based on the look-up and a cell reselection procedure is performed using the cell identifier.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.
