The present disclosure provides a method (800) in a first terminal device. The method (800) includes: obtaining (810) a first measurement result for a first link between the first terminal device and a second terminal device and/or a second measurement result for a second link between the first terminal device and a network node; and transmitting (820) the first measurement result and/or the second measurement result. The first measurement result and/or the second measurement result is obtained by measuring the first link and/or the second linkby the first terminal device, or receiving from the second terminal device the first measurement result and/or the second measurement result as obtained by measuring the first link and/or the second link by the second terminal device.

A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network can operate to communicate in a UE to UE (U2U) relay path through a first relay UE with another UE as a source or destination UE according to a direct communication request initiating from the source UE. The UE, as a source UE, can also perform the U2U relay reselection based on a measurement report received from a destination UE.

Deterioration of communication is prevented in a communication apparatus, in which an infrastructure mode and a P2P mode are independently and concurrently executable, according to an embodiment of the present invention. Hence, in a case where the communication apparatus is in a state in which a first mode of executing wireless communication with a communication partner apparatus via an external access point and a second mode of executing wireless communication with an external apparatus without using the external access point are concurrently executable, the following selection is made. That is, a first channel width which is not accompanied by network detection processing is selected.

A communications device configured to transmit signals representing data to one or more in-coverage communications devices forming with the communications device a group, one of the in-coverage communications devices acting as an active relay node for the communications device, so that the in-coverage communications device can transmit signals representing the data to the infrastructure equipment of the mobile communications network, and to receive signals representing the data from the in-coverage communications device acting as the active relay node. The signals transmitted to the in-coverage communications device are received according to a device-to-device communications protocol, wherein the signals transmitted by the communications device or received by the communications device include an identifier which identifies the signals to the in-coverage communications device. One of the other in-coverage communications device can be selected by the infrastructure equipment to act as the active relay node.

A system and a method for a base station to reduce signaling overhead in device-to-device (D2D) communication are provided. The method includes a list of one or more destination identities (IDs) in a signaling message from at least one of UE and source base station, receiving a destination index in a buffer status report (BSR) from UE to request dedicated resources for transmitting D2D communication packets to a destination, determining the destination ID corresponding to destination index received in the BSR using the list of one or more destination IDs received from at least one of UE and source base station wherein the destination index is the index of destination ID in the list of destination IDs received, and allocating resources to the UE based on the determined destination ID.

In accordance with an embodiment, a device identification method includes: obtaining historical connection data of the second device belonging to a wireless local area network (WLAN), where the historical connection data reflects a connection status between each of at least one terminal device that used to be connected to the second device and the WLAN; and determining the second device as an edge wireless access point (AP) device based on off-net terminal device data of the second device.

A processing method includes: determining at least one of first conditions in a first situation, by a second wireless apparatus in a system which includes a first wireless apparatus and a plurality of the second wireless apparatuses, the first situation being when the wireless apparatus operates in an idle mode and when communication between the wireless apparatus and the one other second wireless apparatus is performed via a first channel, the first conditions including whether a quality of the first channel is lower than a predetermined quality and whether a switching instruction is received; and executing a first process by the second wireless apparatus when the at least one of first conditions is met, the first process including establishing a second channel between the second wireless apparatus and the first wireless apparatus, and switching from communication via the first channel to communication via the second channel.

The technology of this application relates to a relay communication method. After receiving first information sent by a first terminal device, a first radio access network device may determine, based on the first information, a second terminal device that provides, in a target cell, a relay service for the first terminal device, where the first information is used to indicate that the first terminal device is a terminal device with limited uplink power. The first radio access network device sends second information to a second radio access network device, where the second information is used to indicate the second terminal device that provides, in the target cell, the relay service for the first terminal device.

Various embodiments of the present disclosure provide a method for communication services. The method which may be performed by a user equipment (UE) includes receiving edge related information transmitted by a server. The edge related information indicates an edge application server (EAS) which is serving or to serve another UE paired with the UE. In accordance with an exemplary embodiment, the method further includes establishing a connection with the EAS indicated by the edge related information.

The communication system includes: a first base station to which a first communication terminal is connected, the first communication terminal supporting terminal-to-terminal communication in which communication terminals directly communicate with each other; and a second base station to which a second communication terminal is connected, the second communication terminal supporting the terminal-to-terminal communication, and in a case where the second base station receives a handover request for the first communication terminal to connect to the second base station via the second communication terminal, the second base station transmits, to the first communication terminal and the second communication terminal, communication configuration information indicating the content of a configuration for the first communication terminal and the second communication terminal to perform terminal-to-terminal communication therebetween.
