    摘要： A method and apparatus are described for negotiating “keep-alive” message frequencies of applications running on a wireless transmit/receive unit (WTRU). A node may include a negotiation and synchronization function (NSF) configured to collect information including frequencies of keep-alive messages required by application servers for different applications running on the WTRU, and send a keep-alive message frequency negotiation request message to the application servers to negotiate for a more proper frequency for each application on behalf of the WTRU. The node may further include a buffering and caching function (BCF) configured to cache and buffer application specific attributes including an indication of whether each of the applications needs to send periodic keep-alive messages to an associated application server. The node may be a packet data network gateway, a negotiation and caching gateway, or a serving gateway.

    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. The apparatus may detect, in a PDCCH monitoring occasion of the plurality of PDCCH monitoring occasions in the monitored portion, paging downlink control information (DCI).

    摘要： The present application is at least directed to an apparatus. The apparatus includes a non-transitory memory including instructions stored thereon for beam link pairing the apparatus to a router in a new radio. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing the instructions of transmitting physical random access channel (PRACH) preambles through a set of uplink transmission beams in a subframe. The processor is also capable of executing the instructions of signaling a beam ID of the set of uplink transmission beams. The processor is further capable of executing the instructions of monitoring a physical downlink control channel (PDCCH) for a random access response (RAR) including a random access radio network temporary identifier (RA-RNTI). The processor is even further capable of executing the instructions of determining the RA-RNTI corresponds to the transmitted PRACH preambles.

    摘要： Embodiments described herein include DRX operations that address impacts of beamforming to current DRX operations. It is recognized herein that the new NR-PDCCH may affect the downlink control channel monitoring in DRX operations. DRX embodiments described herein also address the impact of new NR-PDCCH to DRX operations. It is further recognized herein that, in NR, multiple DRX configurations may be supported, and Ll/2 signaling (such as MAC CE based) can be used for dynamic DRX configuration switching. Embodiments described herein include signaling and other mechanisms that support multiple DRX configurations, and switching between multiple configurations. Embodiments described herein also include DRX operations that address the impact of HARQ design in NR to DRX operations. Embodiments described herein further include DRX operations that address the impact of multiple SR configurations in NR to DRX operation.

The network includes a downlink sweeping subframe, an uplink sweeping subframe and a regular sweeping subframe. The apparatus also includes a processor operably coupled to the non-transitory memory. The processor is configured to execute the instructions of selecting an optimal downlink transmission beam transmitted by the cell during the downlink sweeping subframe. The processor is also configured to execute the instructions of determining an optimal downlink reception beam from the optimal downlink transmission beam. The processor is further configured to execute the instructions of determining a random access preamble and a physical random access channel (PRACH) resource via resource selection from the optimal downlink transmission beam. The processor is even further configured to execute the instructions of transmitting, to a node, the selected random access preamble via the PRACH resource and an uplink transmission beam of the uplink subframe.
