摘要： An apparatus in accordance with the present application may monitor a sidelink (SL) connection. The apparatus includes processing circuitry that receives signals in a protocol stack to perform SL-radio link monitoring (SL-RLM), and determines, according to the signals, whether a SL-radio link status reporting dio link failure (RLF) has occurred. The signals may include hybrid automatic repeat request (HARQ) feedback. In a case that the signals include a HARQ-NACK, the processing circuitry determines that the SL-RLF has occurred. The processing circuitry further receives configuration information related to the SL-RLM for the signals, the configuration information including configurations for measurement quantities of the signals and a condition for declaring SL-RLF, configures, according to the configuration information, lower layers of the protocol stack for the SL-RLM for the signals, and performs SL-RLM measurements of the measurement quantities.

摘要： Methods and apparatus are disclosed pertaining to paging for Unlicensed New Radio (NR-U). Methods include means to: perform paging using multiple paging occasions (POs) during a DRX Cycle, perform paging using a paging window, perform paging using a PO comprised of multiple sweeps and/or repetitions, signal DL channel access indication for paging, and perform paging using dynamic DRX. In accordance with one embodiment, an apparatus may receive a signal comprising a plurality of POs, wherein each PO comprises a plurality of physical downlink control channel (PDCCH) monitoring occasions. The apparatus may monitor, based on receiving an identifier associated with the apparatus, a portion of the plurality of paging occasions.

摘要： Different sidelink resource configurations and allocation schemes may be controlled by an interface, such as the Uu interface. The radio resource control configurations may include dynamic assignment of broadcast sidelink transmission, unicast sidelink transmission, or group sidelink transmission. There may be radio resource control configured static resource allocation for broadcast sidelink transmission, unicast sidelink transmission, or group sidelink transmission.

摘要： Methods, systems, and apparatus designed to support flexible carrier bandwidths in new radio. Multiple carrier bands may be combined into a single composite carrier depending on channel availability in the carrier bands. A composite carrier indicator (CCI) indicates to network devices, the available carrier bands within the channel occupancy time. In addition, bandwidth part inactivity time is suspended when channel access is not available.

摘要： The present application is directed to an apparatus including a non-transitory memory including instructions stored thereon for monitoring synchronous signals and physical broadcast channels (SSBs) from a network node. The apparatus also includes a processor, operably coupled to the non-transitory memory, configured to execute a set of instructions. The instructions include configuring the apparatus for a STTC (SSB Transmission Timing Configuration). The STTC is a time interval with plural locations accommodating transmission of the SSBs. The instructions also include monitoring the STTC for the SSBs. The instructions further include determining a first one of the SSBs in a first slot of a subframe in a scheduled SSB transmission in the STTC has been transmitted at a first scheduled location, where the transmission of the first one of the SSBs is based upon confirmation of a successful Listen Before Talk (LBT) available channel prior to the scheduled SSB transmission in the STTC.

摘要： Downlink Control Information (DCI) may be expanded, or enhanced, to allow nodes such as UEs, eNBs, NR-nodes, gNBs, and TRPs in M2M, IoT, WoT networks to coordinate activities on PHY, MAC, and RRC layers. For example, DCI fields may be added or enhanced to include, for example, information regarding time resource allocation, frequency resource allocation, mini-slot allocation, and or Code Block Group (CBG) transmission. Such information, or similar information, may be used in operations such as mini-slot operations, Code Block Group (CBG) transmission, group common Physical Downlink Control Channel (PDCCH), grant-free and grant-less operations, response to Beam Failure Recovery Request (BFRR), UL Transmit (TX) beam change, Quasi-Co-Location (QCL) operations, aperiodic CSI-RS transmission and interference measurement, Band Width Part (BWP) operations, and Multi-Transmission and Reception Point (TRP)/Multi-Panel.

摘要： Measurement modeling and filtering may include configurable cell quality derivation method is used for multi-beam based NR networks; a common measurement model that considers different characteristics of the two measurement signals, NR synchronization signal and additional reference signal; and a multi-level measurement filtering approach that handles different mobility scenarios in an NR network. Measurement configuration and procedures may include a measurement gap design during which UE may use to perform measurements for beam sweeping based NR networks; a group of triggering events that may be used to trigger UE mobility management in an NR network; a content format that may be used for the transmission of UE measurement report; a measurement object design (the object on which a UE may perform the measurements) to reduce UE measurement overhead and cost; and a downlink measurement based inter-cell handover procedure that may be used in an NR network.

摘要： User equipment (UE) in beam-centric telecommunications cell may use a variety of listen-before-talk (LBT) procedures and hybrid channel access procedures for uplink transmissions are on different beams and configured or scheduled in contiguous or non-contiguous mode. UE behavior may be based on the LBT result across the different beams. A gNB may indicate LBT occasions to UEs. The UL numerology may be adjusted without LBT while near the end of a gNB's maximum channel occupancy time (MCOT). A gNB may use LBT procedures, before down link transmissions, using data, control, and reference signals, etc., across different beams.
