Abstract: The present disclosure provides a user terminal accessing method and apparatus, a user terminal, and a storage medium. A target relay user terminal receives a connection establishment request message transmitted by a user terminal through a sidelink communication interface, where the connection establishment request message carries an identity identifier of the user terminal, the identity identifier of the user terminal is used to indicate that the user terminal is accessing the target relay user terminal using an identity of a remote user terminal, or accessing the target relay user terminal using an identity of a relay user terminal. Through the solution, it can be ensured that, when the user terminal needs to access the target relay user terminal, the target relay user terminal can correctly identify identity information of the user terminal requesting to access, and perform an operation corresponding to the identity of the user terminal, guaranteeing normal operation of a system.

Abstract: The present application relates to the technical field of wireless communications. Provided are a communication method, and a terminal. In the present application, a first terminal sets a first PC5-S message of a unicast type, which message is sent to a second terminal, to be a broadcast type or a multicast type, such that the second terminal can establish a corresponding packet data convergence protocol (PDCP) receiving entity, a radio link control (RLC) receiving entity and a logical channel for the PC5-S message, or after determining that a transmission message is a PC5-S message of a unicast type that is sent by a new terminal, the second terminal processes the transmission message as a message of a broadcast type or a multicast type, and establishes a corresponding PDCP receiving entity, an RLC receiving entity and a logical channel, thereby facilitating the solving of the problem of the second terminal not being able to establish a corresponding PDCP receiving entity, an RLC receiving entity and a logical channel for the unicast message, which is conducive for the terminal to receive the PC5-S message.
