摘要： Some embodiments of the present disclosure provide for configuring channel access mechanisms in a mmWave shared spectrum mobile communication network. The channel access mechanisms are to be used by a user equipment (UE) and a serving node in the UE's serving cell. The configuring may use a single, cell-specific higher layer parameter or a combination of two cell-specific higher layer parameters. The parameters may configure the UE and the node to perform channel sensing before transmitting to initiate a channel occupancy. Alternatively, the UE and the node may be configured to transmit directly without channel sensing. The parameters may configure a receiver (the UE or the node) to perform channel sensing before transmitting a channel idle indication to the transmitter as part of a channel access procedure to initiate a channel occupancy. Alternatively, the parameters may configure the UE and the node to receive without channel sensing.

摘要： Methods, apparatuses and systems are described. A device, in the active state, receives, from a serving transmission point, a device connection identifier (DCID) associated with the device. The device, in the standby state, periodically transmits, to the same or different serving transmission point, an identifying signal that identifies the first device using the DCID, to synchronize the first device with a wireless communications network.

摘要： Methods and devices for uplink-based User Equipment (UE) tracking for UEs operating in a connected inactive operating state are provided. A transmit-receive point (TRP) transmits parameters to a UE that allow the UE to uniquely determine a UE-specific tracking sequence and assigned time-frequency (TF) resource that are independent of a TRP identifier associated with the TRP. The UE determines the UE-specific tracking sequence and assigned TF resource based at least in part on the parameters received from the TRP. While in the connected inactive operating state, the UE transmits a tracking signal that includes the UE-specific tracking sequence in accordance with the assigned TF resource. The TRP receives the tracking signal from the UE, detects the UE in accordance with the UE-specific tracking sequence to produce a UE detection status, and transmits a tracking response to the UE in accordance with the UE detection status.

摘要： Methods and devices for configurable sequence usage for user equipment (UE) uplink reference signaling are provided. In one provided method, a transmission reception point (TRP) in a wireless communication network receives a first UL reference signal (RS) associated with a first UL RS sequence from a first UE and receives a second UL RS associated with a second UL RS sequence from a second UE, the first and second UL RS sequences being non-orthogonal. In another provided method, A UE determines an UL RS sequence based on a UL RS sequence root, the UL RS sequence root being a UE-specific root and being independent of a cell identifier of a cell serving the UE. The UE sends an UL RS associated with the UL RS sequence, the UL RS sequence being a Zadoff-Chu sequence.

摘要： User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.

摘要： A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.

摘要： Some embodiments of the present disclosure relate to processing an SSB, received in one radio frame, to obtain timing information helpful for allowing a UE to determine a boundary for the radio frame. Beneficially, changes in the periodicity of the transmission of SSB sets may allow the UE more frequent opportunities to determine a boundary for the radio frame. However, in the absence of additional information, the UE may not be able to determine a location, for an SSB set, within the radio frame. Aspects of the present application relate to a manner of including the additional information in an SSB and the processing of the SSB to obtain the additional information such that the UE may be assisted, by the additional information, in the task of determining a boundary for the radio frame.
