摘要： Various devices and methods are disclosed to support clustering optimization in a communication system. For example, multiple nodes of the communication system can be segmented into multiple clustering plans. Each clustering plan can include multiple clusters that do not overlap with one another within that clustering plan. At least one of the clusters of one clustering plan can overlap at least one of the clusters of at least one other clustering plan. Each node could be a non-boundary node in at least one cluster of at least one clustering plan. Multiple nodes of the communication system can alternatively be segmented into clusters having expanding and contracting borders.

摘要： A paging method and system in a wireless network for a target device that is enabled to transition between an active state and a standby state, including: tracking a location of a target device within the network while the target device is in the standby state based on a periodic identifying signal from the target device; determining a serving transmission point for the target device based on the tracking; and instructing the serving transmission point to transmit a paging message to the target device.

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： Networks use channel state information reference signals (CSI-RSs) to measure channel conditions between a user equipment (UE) and a transmit/receive point (TRP) in a cell. The resources configured for the transmission of a CSI-RS may be indicated to the UE using higher layer signaling. Measurement results for a CSI-RS are transmitted by the UE in the form of a measurement report. A need exists for signaling designs that aim to provide more flexible and efficient signaling of CSI-RS resource configurations and measurement reports. In some embodiments, CSI-RS resource configurations and measurement reports are resource-specific. The CSI-RS resource configurations may be independent from an identifier of the cell that the CSI-RS is transmitted from, and the measurement reports do not necessarily include the identifier of the cell. Advantages may include allowing the network to freely allocate CSI-RS resources without the need for reconfiguration at the UE side.

摘要： Methods and devices for sounding reference signal (SRS) carrier aggregation are provided. A target device is configured with N (N≥2) SRSs that include a reference SRS and N−1 target SRS. Lower layer signaling, such as a MAC-CE or a DCI message, is used to activate the N−1 target SRS, such that each of the N SRSs is transmitted on a respective carrier component from a common antenna port. The lower level signaling used to activate the target SRS may identify configuration parameters of the target SRS that are to be overridden by the corresponding configuration parameters of the reference SRS. Embodiments of the present disclosure increase the effective SRS bandwidth, which may improve positioning measurement accuracy, while also reducing the higher-layer configuration signaling by activating target SRS in lower layer signaling and overriding some configuration parameters of the target SRS by the corresponding configuration parameters of the reference SRS.
