The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0169] Some embodiments of the present disclosure are described below:

[0170] In some embodiments of the present disclosure, a Sidelink communication method is introduced to support direct communication between terminals. Optionally, the interface between the terminals can be a PC5 interface, where the PC5 interface can be understood as an interface between terminals. Optionally, three transmission modes are supported on Sidelink, such as unicast, multicast, and broadcast, depending on the corresponding relationship between the sending terminal and the receiving terminal.

[0171] In some embodiments of the present disclosure, a terminal may not be directly connected to the base station but may communicate with the base station through the relay of another terminal. The terminal that is not connected to the base station is called a remote terminal (remote UE), and the terminal that provides the relay function is called a relay terminal (relay UE). The remote terminal and the relay terminal communicate through sidelink unicast. This architecture is called U2N (UE to NW) relay.

[0172] In some embodiments of the present disclosure, the relay terminal and the remote terminal may discover each other through a discovery process. After the discovery process is initiated, the terminal may send or receive a discovery signal that carries information such as the terminal's serving cell identifier and terminal identifier.

[0173] In some embodiments of the present disclosure, the sidelink wireless channel quality between a remote terminal and a relay terminal can be characterized by SD-RSRP or SL-RSRP. SD-RSRP is the RSRP (Reference Signal Received Power) of the sidelink discovery signal, and SL-RSRP is the RSRP of the sidelink communication signal. SD-RSRP measurement does not require a unicast connection between terminals, while SL-RSRP measurement does require a unicast connection between terminals.

[0174] In some embodiments of the present disclosure, when a relay terminal experiences a radio link failure, handover, cell reselection, or RRC (Radio Resource Control) connection failure, a notification message (NotificationMessageSidelink) is sent to the connected remote terminal via a sidelink. When the remote terminal receives the notification message, the terminal in the connected state triggers RRC reconstruction, and the remote terminal in the idle state and the inactive state can decide whether to release the connection with the relay terminal. If the connection with the relay terminal is not released, and the notification message indicates that the relay terminal has undergone a handover or cell reselection, the remote terminal also believes that it has undergone a cell reselection.

[0175] In some implementations of the present disclosure, a remote terminal in an idle state or an inactive state sends its own paging information (SL-PagingInfo-RemoteUE) to a relay terminal. The paging information may be carried by RemoteUEInformationSidelink.

[0176] In some embodiments of the present disclosure, the paging information includes a paging identity (SL-PagingIdentityRemoteUE) of the remote terminal and a paging cycle. Optionally, the paging identity of the remote terminal may include at least one of an I-RNTI and an NG-5G-S-TMSI.

[0177] In some embodiments of the present disclosure, the relay terminal may monitor the paging message sent by the network, and the paging message may carry a paging record list (PagingRecordList). Optionally, the paging record list may carry one or more paging records (PagingRecord). Optionally, each paging record carries a paging UE identifier (PagingUE-Identity). Optionally, the paging UE identifier may include at least one of an I-RNTI and an NG-5G-S-TMSI.

[0178] In some embodiments of the present disclosure, if the paging UE identifier carried in the paging message received by the relay terminal is consistent with the paging identifier of the remote terminal, the corresponding paging record is sent to the remote terminal. Optionally, the paging record can be carried via UuMessageTransferSidelink.

[0179] In some implementations of the present disclosure, the paging message may be referred to as paging information.

[0180] In some implementations of the present disclosure, the paging message may carry paging information.

[0181] In some implementations of the present disclosure, the remote terminal may enter a connected state after receiving a paging record.

[0182] In some embodiments of the present disclosure, a remote terminal in an idle or inactive state may send a system information request message to a relay terminal. The system information request message may carry a requested system information identifier. The system information request message may be a sidelink RRC message. Optionally, the sidelink RRC message may be a RemoteUEInformationSidelink message. After receiving the request, the relay terminal obtains the corresponding system information and sends the system information to the remote terminal via a sidelink RRC message. Optionally, the sidelink RRC message may be a UuMessageTransferSidelink message.

[0183] In some embodiments of the present disclosure, a remote terminal may maintain a connection with a network device via one or more relay terminals. The architecture in which a remote terminal maintains a connection with a network device via multiple relay terminals is called a multi-hop U2N relay.

[0184] FIG1B is a schematic diagram illustrating an architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1B , the communication system 100B may include a remote terminal 1011B, a relay terminal 10121B, a relay terminal 10122B, a relay terminal 10123B, and a network device 102B.

[0185] It should be noted that FIG1B is only an exemplary architecture diagram of a communication system including three relay terminals as an example. In other possible communication systems, the number of relay terminals may be more than three or less than three, and there is no limitation on this.

[0186] In some embodiments of the present disclosure, for any device, compared to the device, in a multi-hop U2N relay link, a device closer to the network device is called a parent node device, and a device farther away from the network device is called a child node device.

[0187] In some implementations of the present disclosure, a parent node may also be referred to as a parent node, a parent node, a mother node, etc.

[0188] In some implementations of the present disclosure, a child node may also be referred to as a descendant node, a child node, a child node, etc.

[0189] In some embodiments of the present disclosure, in a multi-hop U2N relay, a remote terminal establishes a PC5 RRC connection with a directly connected relay terminal (e.g., relay terminal 10121B in the figure above). However, this relay terminal may not be within network coverage and therefore cannot obtain network system information or monitor paging messages sent by network devices. This makes it impossible for remote terminals in idle or inactive states to obtain system information and paging messages.

[0190] It should be noted that the terminal in the embodiments of the present disclosure can serve as a remote terminal or a relay terminal in different multi-hop U2N relay links according to actual conditions.
