Embodiments of this application provide a communication method and a related device. The method includes: a network device firstly sends the configuration information to the user equipment, and then the user equipment obtains a first condition based on the configuration information. Then, in a measurement process, the user equipment sends a measurement report to the network device when determining that the first condition is currently met. After obtaining the measurement report, the network device indicates at least one candidate relay device to the user equipment by using a path switch command. The user equipment determines one relay device in the at least one candidate relay device, and communicates with the network device or another network device through the determined relay device.

A controller in a wireless system may, in a first mode, communicate directly with a wireless microphone, via a first wireless protocol, in order to control the wireless microphone, and may, in a second mode, communicate using the first wireless protocol with a wireless access point, in order to control or configure the wireless microphone.

Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. In one aspect a wireless communication technique takes into account the load of a donor gNB before a relay decides to reselect from one donor gNB to another. In another aspect, a wireless communication technique ensures that relays are handed over to base stations that will be able to serve the relay as the mobile relay continues to follow its expected path (e.g. streets or tracks).

Embodiments of this application disclose a communication method and a related apparatus, so that remote UE can communicate with a network via relay UE that resumes or establishes a radio resource control RRC connection, to ensure communication quality of the remote UE. The method includes: A first access network device receives a first message sent by first UE, where the first message includes a first identifier of second UE, and the first identifier is an identifier of the second UE in an RRC inactive state or an RRC idle state. The first access network device pages the second UE based on the first message. The first access network device sends a second message to the first UE, where the second message indicates the first UE to perform path switching, the second message includes a second identifier of the second UE.

A method for centralized device tracking includes: obtaining, at a first UE from multiple sources, first multi-source position information corresponding to a second UE; determining, based on the first multi-source position information, second multi-source position information corresponding to the second UE; identifying a third UE, separate from the first UE, to which the second multi-source position information is relevant; and sending migration information to the third UE, the migration information comprising an identifier of the second UE and comprising the first multi-source position information, or the second multi-source position information, or a combination thereof.

A switching method and a device in a sidelink relay architecture are provided. The method is performed by a remote terminal and includes: receiving a first message from a network device, where the first message includes switching information; and performing, according to the switching information, switching from a source link to a target link, where at least one of the source link and the target link is a relay link.

Methods, apparatuses, systems, etc., directed to performing a change of relay are disclosed herein. In an embodiment, a WTRU may transmit a link modification request message to a target WTRU via a first relay WTRU for requesting a change of relay. The WTRU may receive a link modification accept message from the target WTRU via the first relay WTRU, indicating a (e.g., proposed) second relay WTRU (e.g., identifier). The WTRU may transmit a direct communication request message including the second relay WTRU identifier for indicating to the target WTRU acceptance of the proposed second relay WTRU. The WTRU may a receiving a direct communication accept message from the target WTRU via the second relay WTRU, indicating the traffic may be relayed via the second relay WTRU.

A method performed by a user equipment (UE) in a wireless communication system, the method including: selecting to create a configured sidelink grant corresponding to transmissions of at least one media access control (MAC) protocol data unit (PDU); and triggering a transmission carrier selection procedure based on (i) data being available in a sidelink traffic channel (STCH) associated with one or more carriers, and (ii) there being no configured sidelink grant on any carrier, among the one or more carriers, that is allowed for the STCH.

Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.
