A communication control method according to a first aspect is a method used in cellular communication system including a relay node for relaying communication between a base station and user equipment. The communication control method includes the steps of: broadcasting, by the base station managing a cell belonging to a Non-Public Network (NPN), a system information block including an NPN identifier identifying the NPN to the cell; receiving, by the relay node, the system information block from the base station; and determining, by the relay node, whether an access from the relay node to the cell is permitted, based on the system information block.

A timing adjustment method and a related device. The method includes: adjusting timing of a first link state based on first signaling, where the first link state is a link state of a first relay device or a terminal; and the first signaling is provided by a parent node of the first relay device, or a parent node of the terminal, or a first network-side device, where the parent node is a last-hop device of the first relay device or the terminal.

Certain aspects of the present disclosure provide techniques for wireless communications by a mobile repeater. The mobile repeater measures broadcast signals from one or more target cells as the mobile repeater moves through a network. The mobile repeater selects one of the target cells, based on the measuring and side information. The mobile repeater forwards signals between a user equipment (UE) and the selected target cell.

A device may receive information from a unified database, wherein the information includes a Service Profile Identifier (SPID); select a Quality-of-Service (QoS)-related identifier (ID) at least based on the SPID; and either map a radio bearer to a flow associated with a User Equipment device (UE) or configure a component to map the radio bearer to the flow. After mapping the radio bearer to the flow, the device may send data from the flow to the UE based on the QoS related ID. After configuring the component, the device may forward the SPID to a second component for sending the data from the flow to the UE based on the QoS-related ID.

A (repeater) node may identify a first indication of a waveform switch associated with a first link between a base station and the node or a second link between the node and a UE. A waveform switch associated with the first link may be triggered by the base station or the node. A waveform switch associated with the second link may be triggered by the node or the UE. The waveform switch may correspond to a first switch from an OFDM waveform to an SC waveform or a second switch from the SC waveform to the OFDM waveform. The base station may transmit, to the node, an indication of a post-waveform switch resource mapping between a first waveform associated with the first link and a second waveform associated with the second link. The node may execute the waveform switch associated with the first link or the second link.

Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a control node, an indication of a capability of the first wireless node to perform one or more self-interference cancelation (SIC) procedures between a first antenna array of the first wireless node and a second antenna array of the first wireless node. The first wireless node may receive, from the control node in response to the indication of the capability, a configuration for the first wireless node to use to perform a SIC procedure of the one or more SIC procedures for full-duplex communications. The first wireless node may then communicate, according to the received configuration, with the control node, a control node, or any combination thereof, using the first antenna array and the second antenna array.

A control method implemented by a communication device. The control method includes: acquiring a current location and current capacities of a drone; selecting a destination point that can be reached by the drone according to the location and capacities thereof, the destination point being located in the coverage area of a point of access to a mobile communication network; and providing the drone with instructions specifying the destination point towards which the drone is to travel and communication operations to be carried out in connection with the mobile communication network. Once the instructions are obtained, the drone moves towards the destination point and performs the communication operation as soon as it reaches the destination point or as soon as the connection quality reaches a satisfying level.

A method for operating a relay node during a handoff from a first controller to a second controller includes receiving a first instruction from the first controller to discontinue using a first set of wireless backhaul link resources allocated to the relay node by the first controller and to temporarily use a second set of wireless backhaul link resources dedicated by the second controller. The method also includes receiving a second instruction from the second controller to discontinue using the second set of wireless backhaul link resources and to begin using a third set of wireless backhaul link resources allocated to the relay node by the second controller.

A method and device are disclosed from the perspective of a User Equipment-to-User Equipment (UE-to-UE) Relay to forward sidelink UE capability information. In one embodiment, the method includes the UE-to-UE Relay receiving a first sidelink UE capability information from a first UE. The method further includes the UE-to-UE Relay transmitting the first sidelink UE capability information of the first UE and a second sidelink UE capability information of the UE-to-UE Relay to a second UE or transmits a combined sidelink UE capability information to the second UE, wherein the combined sidelink UE capability information is derived from the first sidelink UE capability information and the second sidelink UE capability information.

To measure the channel quality of the own cell accurately in a condition where there is no interference from a neighbor cell. A wireless communication terminal according to the invention is a wireless communication terminal to be connected to a base station for transmitting and receiving data to/from the base station, the wireless communication terminal including: a receiver that receives a signal which includes control information provided for measuring a channel quality of own cell from the base station; an extractor that extracts the control information from the signal received by the receiver; a measurement section that measures, on the basis of the control information, the channel quality of the own cell in a domain where a neighbor cell does not transmit a signal; and a transmitter that transmits a measurement result of the channel quality of the own cell measured by the measurement section, to the base station.
