摘要： The present disclosure provides a wireless communication method and device, and provides a solution for a terminal device to determine whether to perform SIM card switching, capable of reducing the complexity of the terminal device. The wireless communication method is performed by a terminal device which supports a plurality of Universal Subscriber Identity Module, USIM, cards. The method includes: receiving, by the terminal device, a first message transmitted by a first network; and establishing, by the terminal device, a connection with the first network in response to the first message, wherein the first message is a paging message. The first message is transmitted by the first network when determining that the terminal device is required to establish the connection with the first network, USIM-1 of the terminal device corresponds to the first network and USIM-2 of the terminal device corresponds to a second network, and the terminal device is in a Radio Resource Control, RRC, connected state and/or a Connection Management, CM, connected state with the second network. Whether the terminal device is required to establish the connection with the first network is determined by the first network based on a first policy, and the first policy includes a service priority. The service priority identifies a service that requires the terminal device to connect to the first network or a service that does not require the terminal device to connect to the first network. All or part of information of the first policy originates from the terminal device, and the method further includes: transmitting, by the terminal device, part or all of the information in the first policy to the first network via a Non-Access Stratum, NAS, message.

摘要： Methods for relay transmission, a relay user equipment (UE), and a remote UE are provided in implementations of the disclosure. The method includes the following. A relay UE receives a first message transmitted by a network device, where the first message contains information of a back-off (BO) timer. During running of the BO timer, the relay UE is restrained from transmitting a message used for device discovering, or transmits a second message, where the second message is used to indicate that a relay service on the relay UE is constrained or the relay UE is unable to be used as a relay.
