Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The following explains some concepts and/or terms related to the relay configuration method, device and user equipment provided in the embodiments of the present application.

1. Sidelink (sidelink): may also be referred to as a side link, or the like. In a long term evolution (long term evolution, LTE) system, sidelink is supported, and is used for data transmission between UEs directly without a network device.

The design of LTE sidelink is applicable to specific public safety transactions (e.g., emergency communication in disaster sites such as fire or earthquake), or internet of vehicles (vehicle to everything, V2X) communication, etc. The internet of vehicles communication includes various services such as basic security type communication, advanced (automatic) driving, formation, sensor expansion, and the like. Since LTE sidelink only supports broadcast communications, it is mainly used for basic security class communications, and other advanced V2X services with strict QoS requirements in terms of latency, reliability, etc. will be supported by NR sidelink.

The 5G NR system can be used for the working frequency band above 6GHz which is not supported by LTE, and supports larger working bandwidth, but the NR system of the current version only supports the interface between the base station and the terminal, but does not support the sidelink interface of direct communication between the terminals. The link interface of the sidelink may be referred to as a PC5 interface.

2. Relay (relay) mechanism: the relay technology in the wireless communication system is to add one or more relay nodes between the base station and the terminal, and is responsible for forwarding the wireless signal once or more times, i.e. the wireless signal can reach the terminal only through multiple hops. The wireless relay technology not only can be used for expanding cell coverage and compensating cell coverage blind points, but also can improve cell capacity through space resource multiplexing. For indoor coverage, the relay technology can also play a role in overcoming penetration loss and improving indoor coverage quality. For example, taking two-hop relay as an example, the wireless relay divides a link of a base station-UE into two links of the base station-relay station and the relay station-UE, so that a link with poor quality is replaced by two links with good quality, and higher link capacity and better coverage are obtained. The relay supported in the LTE at present is a UE-to-network relay, namely one end of the relay is connected with the UE, and the other end is connected with the network side. The UE connected to the relay is called a remote (remote) UE. The Uu interface is between the relay UE and the base station, and the sidelink interface is between the relay UE and the remote UE. The relay UE is typically open and may serve any remote UE.

It is noted that the techniques described in embodiments of the present application are not limited to long term evolution (long term evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (code division multiple access, CDMA), time division multiple access (time division multiple access, TDMA), frequency division multiple access (frequency division multiple access, FDMA), orthogonal frequency division multiple access (orthogonal frequency division multiple access, OFDMA), single-carrier frequency division multiple access (single-carrier frequency-division multiple access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the present application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, these techniques are also applicable to applications other than NR system applications, such as the 6th generation (6th Generation,6G) communication system.

Exemplary, fig. 1 shows a schematic architecture of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system may include a UE 01 and a network device 02. Wherein a connection and communication may be established between the UE 01 and the network device 02.

The UE in the embodiment of the present application may also be referred to as a terminal device, where the UE may be a mobile phone, a tablet (tablet personal computer), a laptop (laptop) or a terminal-side device such as a notebook, a personal digital assistant (personal digital assistant, PDA), a palmtop, a netbook, an ultra-mobile personal computer (mobile personal computer, UMPC), a mobile internet device (mobile internet device, MID), a wearable device or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), and the wearable device includes: a bracelet, earphone, glasses, etc. It should be noted that, the embodiments of the present application are not limited to specific types of UEs.

The network device in the embodiments of the present application may be a base station or a core network, where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (base transceiver station, BTS), a radio base station, a radio transceiver, a basic service set (basic service set, BSS), an extended service set (extended service set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, a transmission receiving point (transmitting receiving point, TRP), or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary so long as the same technical effect is achieved, and it should be noted that, in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The following describes in detail a relay configuration method provided in the embodiment of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

In the embodiment of the present application, in the relay scenario, the remote UE may be located outside the coverage area of the base station itself, but may be connected to the base station through the relay UE, in this case, the present application provides a scheme that whether the base station may perform some necessary radio resource configuration for the remote UE through relay UE transfer. Alternatively, the remote UE may be located within the coverage of the base station itself or enter the coverage from outside the coverage, in which case the present application also provides a scheme of whether the base station should directly transmit the configuration to the remote UE or should transfer some necessary radio resource configuration to the remote UE through the relay UE.

The scheme of the embodiment of the application is suitable for an L2 architecture and an L3 architecture, and is also suitable for a UE-to-network relay architecture and a UE-to-UE relay architecture.

Wherein, L3 architecture features: the relay UE has a complete protocol stack, i.e. in addition to the basic L2 transport protocol stacks of radio link layer control protocol (radio link control, RLC), medium access control sublayer protocol (media access control, MAC) and physical layer Protocol (PHY), also has protocol stacks of radio resource control layer (radio resource control, RRC), service data adaptation protocol (service data adaptation protocol, SDAP) and packet data convergence protocol (packet data convergence protocol, PDCP) for carrying and transmitting data of the remote UE. For a UE-to-UE relay architecture, a complete protocol stack is arranged between a remote UE 1 and a relay UE, and a complete protocol stack is also arranged between the relay UE and a remote UE 2; for the UE-to-network relay architecture, a complete protocol stack exists between remote UE and relay UE, and a complete protocol stack also exists between relay UE and base station.

Characteristics of L2 architecture: the relay UE does not have a complete protocol stack for the relayed data, that is, there is no corresponding protocol stack such as RRC, SDAP, PDCP, etc. except the basic L2 transmission protocol stacks such as RLC, MAC, and PHY, and only RLC is used to carry and transmit the data of the remote UE. For the UE-to-network relay architecture, peer-to-peer RRC, SDAP, PDCP and other protocol stacks are arranged between remote UE and a base station, but only the RLC layer and the lower protocol stack are arranged between remote UE and relay UE, and only the RLC layer and the lower protocol stack are arranged between relay UE and the base station; for the UE-to-UE relay architecture, peer protocol stacks such as RRC, SDAP and PDCP are arranged between the remote UE1 and the remote UE 2, but only the RLC layer and the following protocol stacks are arranged between the remote UE1 and the remote UE, and only the RLC layer and the following protocol stacks are arranged between the remote UE and the remote UE 2.

In addition, no matter the L2 architecture, the L3 architecture, the UE-to-network relay, the UE-to-UE relay, and there may be additional adaptation layers (adaptation layers) at the remote UE, the relay UE, and the base station, the protocol stack is not limited in the embodiments of the present application.

An embodiment of the present application provides a method for configuring a relay, and fig. 2 shows a flowchart of the method for configuring a relay provided in the embodiment of the present application. As shown in fig. 2, the method for configuring a relay provided in the embodiment of the present application may include the following steps 201 and 202.

Step 201, the UE acquires target information.

Step 202, the UE acquires relay related configuration information according to the target information.

In an embodiment of the present application, the target information includes at least one of the following: the first information is used for indicating whether the UE is in the direct coverage of the remote equipment or not, the second information is used for indicating whether the UE is connected with the remote equipment or not, the relay related configuration information is used for relay related communication of the UE, and the remote equipment is remote UE or network equipment of the UE.

It should be noted that, in the embodiment of the present application, the UE may be understood as a remote UE in relay communication, and the remote device may be a remote UE of an opposite end of the UE, that is, a remote UE of an opposite end connected to the UE through a relay under a UE-to-UE relay architecture.

Alternatively, in the embodiment of the present application, the relay related configuration information may be sent by RRC signaling (RRC related configuration information), or may also be sent by MAC CE, or may also be preconfigured.

It should be noted that, in the embodiment of the present application, the direct coverage of the remote device (for example, the direct coverage of the base station) may be understood as: the remote UE cannot directly receive the broadcast message or RRC dedicated signaling of the base station, and is out of direct coverage of the base station. And, if the remote UE connects to the base station through the relay UE at this time, the broadcast message or RRC dedicated signaling of the base station may be received, which may be referred to as "out of direct coverage of the base station, but the base station is connected through the relay UE", which may be referred to as "within the coverage of the base station" or not, of course, the embodiment of the present application is not limited. Direct coverage of a remote device (e.g., direct coverage of a base station) can be understood as: the remote UE may directly receive the broadcast message or RRC dedicated signaling of the base station, and then the remote UE is within the direct coverage of the base station.

Alternatively, in the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201a, step 201b, or step 201 c.

Step 201a, the UE receives relay related configuration information sent by the target device according to the target information.

In an embodiment of the present application, the target device includes at least one of the following: relay devices and remote devices.

It should be noted that, in the embodiment of the present application, the UE receiving the relay related configuration information sent by the target device may be understood as: the UE receives the relay related configuration information from the target device, i.e., the UE may receive the relay related configuration information only from the relay device and may not receive the relay related configuration information from the remote device; alternatively, the UE may receive relay-related configuration information only from the remote device and cannot receive relay-related configuration information from the relay device; alternatively, the UE may receive relay related configuration information from both the relay device and the remote device, but the actual relay related configuration information may only come from the relay device or only come from the remote device during each configuration reception process; alternatively, the UE may receive relay related configuration information from both the relay device and the remote device, and each configuration reception procedure related configuration information may come from both the relay device and the remote device. In addition, the UE receiving relay related configuration information from the relay device can be understood as: the relay related configuration information may be sent directly by the relay device (i.e. from the relay device itself), or the relay related configuration information may be sent by a remote device forwarded by the relay device.

Step 201b, the UE receives relay related configuration information sent by the target device according to the target information and the first indication information.

In this embodiment of the present application, the first indication information is used for indicating, by the target device, a transmission mode of the relay related configuration information.

Note that, the transmission method of the relay related configuration information may be understood as: the relay related configuration information is directly sent by the remote device, or directly sent by the relay device, or forwarded by the relay device (i.e., the remote device sends to the relay device, which sends to the UE).

Optionally, in this embodiment of the present application, for the L2 architecture, the remote UE is located in the direct coverage area of the base station, and if the remote UE is already connected to the base station through the relay UE, the remote UE may determine, based on the indication (i.e., the first indication information) of the base station, from which device to receive the relay related configuration information and the transmission manner of the data plane data of the remote UE, that is, determine that the relay related configuration information (and/or the data plane data) is from a Uu interface directly or through relay.

The first instruction information may be sent by the target device, and the relay related configuration information may be sent by the target device, where the device sending the first instruction information is the same as or different from the device sending the relay related configuration information. For example, the first indication information may be sent by the remote device to the UE to instruct the UE to receive relay related configuration information from the relay device. Alternatively, the first indication information may be sent by the relay device to the UE to instruct the UE to receive relay related configuration information from the remote device.

Step 201c, the UE obtains relay related configuration information predefined, preconfigured or agreed by a protocol according to the target information.

It should be noted that, a specific method for receiving relay related configuration information sent by the target device by the UE or obtaining relay related configuration information predefined, preconfigured or agreed by a protocol will be described in the following embodiments, which are not described herein.

Alternatively, in an implementation manner of the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201d or step 201 e.

Step 201d, the UE receives the relay related configuration information sent by the relay device when the UE is out of the direct coverage of the remote device and the UE is connected to the remote device through the relay device.

Step 201e, in the case that the UE is out of the direct coverage of the remote device and the UE is connected to the remote device through the relay device, the UE acquires relay related configuration information predefined, preconfigured or agreed by a protocol.

Optionally, in the embodiment of the present application, the method for acquiring the relay related configuration information is determined by any one of the following: second indication information, UE and protocol conventions. The second indication information is used for indicating the acquisition mode of the relay related configuration information by the remote equipment.

It should be noted that, in the case where the UE is out of direct coverage of the remote device and the UE is connected to the remote device through the relay device, whether the UE performs the above 201d or the above step 201e may be determined by the second instruction information, or determined by the UE itself, or agreed by a protocol.

For example, for the L2 architecture, if the remote UE is located outside the direct coverage area of the base station, and the remote UE is connected to the base station through the relay UE, since the peer RRC, SDAP, PDCP and other protocol stacks exist between the remote UE and the base station, at this time, the base station may perform RRC radio resource configuration and related parameter configuration for the remote UE through relay UE. The RRC radio resource configuration and the related parameter configuration may be that the base station sends the RRC radio resource configuration and the related parameter configuration to the relay UE in a system message, and then the relay UE sends the RRC radio resource configuration and the related parameter configuration to the remote UE, or sends the RRC radio resource configuration and the related parameter configuration to the relay UE in an RRC dedicated signaling mode, and then the relay UE sends the RRC dedicated signaling to the remote UE. When the relay UE sends to the remote UE, the relay UE may send to the remote UE in a broadcast, multicast or unicast manner.

For the L3 architecture, if the remote UE is located outside the direct coverage area of the base station and the remote UE is connected to the base station through the relay UE, the UE may use the relay related configuration information of the pre-configuration (factory pre-configuration or base station pre-configuration), or the base station may perform RRC radio resource configuration and related parameter configuration for the remote UE through relay UE transfer.

Alternatively, in another implementation manner of the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201f or step 201 g.

In step 201f, when the UE is out of direct coverage of the remote device and the UE is not connected to the remote device, after the UE establishes a connection with the relay device, the UE receives relay related configuration information sent by the relay device.

For example, for the L2 architecture, if the remote UE is located outside the direct coverage area of the base station and the remote UE is not connected to the base station through the relay UE, the remote UE may find the relay UE through the search procedure and establish a connection, and wait for the subsequent base station to perform RRC radio resource configuration and related parameter configuration for the remote UE through the relay UE.

Also exemplary, for the L3 architecture, if the remote UE is located outside the coverage area of the base station and the remote UE is not yet connected to the base station through the relay UE, the remote UE may use the pre-configured relay related configuration information.

Step 201g, the UE acquires relay related configuration information predefined, preconfigured or agreed by a protocol in a case that the UE is out of direct coverage of the remote device and the UE is not connected with the remote device.

Alternatively, in the embodiment of the present application, the above-mentioned "UE receives the relay related configuration information sent by the relay device" in step 201d (or step 201 f) may be specifically implemented by step 201d1 or step 201d2 described below.

In step 201d1, the UE receives a system message sent by the relay device, where the system message includes relay related configuration information.

In step 201d2, the UE receives an RRC dedicated signaling sent by the relay device, where the RRC dedicated signaling includes relay related configuration information.

It may be appreciated that the remote device may send the relay related configuration information to the relay UE in the form of a system message, and then to the remote UE by the relay UE, or the remote device may send the relay related configuration information to the relay UE by the relay UE and then to the remote UE by means of RRC dedicated signaling.

Alternatively, in yet another implementation manner of the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201 h.

In step 201h, when the UE is in the direct coverage of the remote device and the UE is connected to the remote device through the relay device, the UE receives the relay related configuration information sent by the target device.

It should be noted that, the UE being in direct coverage of the remote device may be understood as: the UE is always in the direct coverage of the remote device, or the UE may enter the direct coverage of the remote device from outside the direct coverage of the remote device.

Optionally, in the embodiment of the present application, the base station may send the relay related configuration information to the relay UE, and then the relay UE forwards the relay related configuration information to the remote UE, where the remote UE does not obtain the relay related configuration information from the base station through its Uu interface. For example, the remote UE does not initiate the RRC connection setup procedure due to relay communication at this time; if a link switch is triggered, a direct link with the base station is switched, and then subsequent relay related configuration information can be directly sent to the remote UE by the base station.

Optionally, in the embodiment of the present application, before "the UE receives the relay related configuration information sent by the target device" in the above step 201h, the method for configuring the relay provided in the embodiment of the present application further includes the following step 301, step 302 or step 303.

Step 301, the UE disconnects from the relay device.

In step 302, the UE directly establishes a connection with a remote device.

In step 303, the UE disconnects from the relay device and directly establishes a connection with the remote device.

It can be understood that, in the case that the UE is in the direct coverage of the remote device and the UE is connected to the remote device through the relay device, the UE may first actively disconnect the connection with the relay device, and then receive the relay related configuration information from the target device; and/or the UE may first actively establish a connection with the remote device and then receive relay related configuration information from the target device.

After the UE disconnects from the relay device, the UE cannot perform transmission and reception of data (e.g., relay related configuration information and/or data plane data) through a unicast or a dedicated connection between the UE and the relay device, but in the case where transmission and reception of data in a multicast or broadcast format is supported between the relay device and the UE, the UE may perform data transmission through the relay device.

Alternatively, in the embodiment of the present application, the above-mentioned "UE receives the relay related configuration information sent by the target device" in step 201h may be specifically implemented by step 201h1 or step 201h2 described below.

In step 201h1, when the relay related configuration information is the configuration information corresponding to the relay related service, the UE receives the relay related configuration information sent by the relay device.

In step 201h2, if the relay related configuration information is the configuration information corresponding to the non-relay related service, the UE receives the relay related configuration information sent by the remote device.

It will be appreciated that the relay related configuration information of the remote UE may be derived from relay UE relay or direct Uu interface (i.e. received directly from the base station) depending on the specific content of the relay related configuration information. Specifically, if the relay related configuration information is for a non-relay related service, the relay related configuration information may be from a Uu interface, and if the relay related configuration information is for a relay related service, the relay related configuration information is from relay UE.

Alternatively, in the embodiment of the present application, the above-mentioned "UE receives the relay related configuration information sent by the target device" in step 201h may be specifically implemented by the following step 201h 3.

Step 201h3, the UE receives the RRC dedicated signaling sent by the relay device, and receives the system message sent by the remote device, where both the RRC dedicated signaling and the system message include relay related configuration information.

Optionally, in the embodiment of the present application, the UE may receive the dedicated RRC radio resource configuration and the related parameter configuration from the relay device, and read the system message of the base station to obtain the broadcasted RRC radio resource configuration and the related parameter configuration.

Optionally, in the embodiment of the present application, after the step 201h, the method for configuring a relay provided in the embodiment of the present application further includes the following step 401.

Step 401, the UE sends or receives data plane data of the UE through the target device.

It should be noted that, the UE transmitting or receiving data plane data of the UE through the target device may be understood as: the UE transmits data plane data of the UE to the target device or the UE receives data plane data from the target device.

It should be noted that, the Relay related configuration information and the data plane data may come from the same link (direct Uu interface or Relay), or may come from different links, that is, the UE may receive the Relay related configuration information from the Relay device, and send or receive the data plane data through the Relay device; alternatively, the UE may receive relay related configuration information from the relay device and transmit or receive data plane data through the remote device; alternatively, the UE may receive relay related configuration information from the remote device and transmit or receive data plane data through the remote device; alternatively, the UE may receive relay related configuration information from the remote device and transmit or receive data plane data through the relay device.

Alternatively, in the embodiment of the present application, the above step 401 may be specifically implemented by the following step 401a, step 401b, or step 401 c.

In step 401a, in the case that the UE is disconnected from the relay device, the UE sends or receives data plane data of the UE through the target device.

Step 401b, in the case that the UE directly establishes a connection with the remote device, the UE sends or receives data plane data of the UE through the target device.

In step 401c, in the case that the UE disconnects from the relay device and directly establishes a connection with the remote device, the UE sends or receives data plane data of the UE through the target device.

It should be noted that, after executing the step 301 (or the step 302 or the step 303), the UE may execute the step 201h of "the UE receiving the relay related configuration information sent by the target device" and the step 401, that is, in a case that the UE is in a direct coverage area of the remote device and the UE is connected to the remote device through the relay device, the UE may actively disconnect the connection with the relay device, then receive the relay related configuration information from the target device, and send or receive data plane data of the UE through the target device; and/or, the UE may first actively establish a connection with the remote device, then receive relay related configuration information from the target device, and send or receive data plane data of the UE through the target device.

Illustratively, in the case where the UE is in direct coverage of the remote device and the UE is connected to the remote device through the relay device, the remote UE disconnects from the relay UE, and at this time, the remote UE may communicate with the base station directly through the Uu interface, for example, receive relay related configuration information from the base station, and transmit data plane data with the base station.

Also for example, in the case that the UE is in the direct coverage of the remote device and the UE is connected to the remote device through the relay device, the remote UE continues to connect to the base station through the relay UE, where the remote UE may directly receive the relay related configuration information from the base station through the Uu interface, and perform data plane data transmission between the relay device and the base station through the relay device.

Optionally, in the embodiment of the present application, before the step 401, the method for configuring a relay provided in the embodiment of the present application further includes a step 501, a step 502, or a step 503 described below.

Step 501, the UE disconnects from the relay device.

Step 502, the UE establishes a connection directly with a remote device.

In step 503, the UE disconnects from the relay device and directly establishes a connection with the remote device.

It can be understood that, when the UE is in the direct coverage of the remote device and the UE is connected to the remote device through the relay device, the UE receives relay related configuration information from the target device, then actively disconnects from the relay device, and then sends or receives data plane data of the UE through the target device; and/or the UE receives the relay related configuration information from the target equipment, then actively establishes connection with the remote equipment, and then sends or receives data plane data of the UE through the target equipment.

Alternatively, in yet another implementation manner of the embodiment of the present application, the above step 201 may be specifically implemented by the following step 201 i.

In step 201i, when the UE is in the direct coverage of the remote device and the UE is not directly connected to the remote device, the UE receives a system message sent by the relay device or the remote device, where the system message includes relay related configuration information.

In the embodiment of the present application, the relay related configuration information of the remote UE is from the relay device or the direct remote device, and depends on the direct connection state of the remote UE and the remote device, and the connection state of the remote UE and the remote device through the relay device.

In one approach, if the remote UE has a direct RRC connection with the remote device (e.g., due to relay traffic or other traffic/reasons, RRC connection establishment is triggered, or a handover from a relay link to a direct link is triggered), then the relay related configuration information comes from the direct remote device.

In another way, if the remote UE has no direct RRC connection with the remote device, but is connected to the remote device through the relay device, the relay related configuration information is forwarded from the relay device, or the UE may receive the dedicated RRC radio resource configuration and the related parameter configuration from the relay device, and read the system message of the base station to obtain the broadcasted RRC radio resource configuration and the related parameter configuration.

In another manner, if the remote UE does not have a direct RRC connection with the remote device, or is not connected to the remote device through the relay device (e.g., there is no PC5-RRC connection between the remote device and the relay device, or the relay device is in an RRC idle (idle) state or inactive (active) state), the remote UE may obtain the broadcasted RRC radio resource configuration and related parameter configuration by reading a system message of the remote device through the Uu interface, or the remote UE may obtain the broadcasted RRC radio resource configuration and related parameter configuration by transferring a system message of the remote device through the relay device.

For example, for the L3 architecture, the remote UE is located in the coverage area of the base station, and the remote UE may obtain the RRC radio resource configuration and related parameter configuration from its Uu interface. Specifically, the RRC connection state determines to acquire system information or dedicated relay related configuration information, for example, acquire system information in idle state or inactive state, and acquire dedicated RRC radio resource configuration and related parameter configuration in connected state.

The embodiment of the application provides a configuration method of a relay, and a UE can acquire relay related configuration information according to target information (whether the UE is in a direct coverage area of a remote device and/or whether the UE is connected with the remote device). In the relay scenario, the UE may accurately obtain the required relay related configuration information according to the relationship between the direct coverage of the UE and the remote device and/or the connection relationship between the UE and the remote device, so as to perform relay related communication, instead of directly receiving the relay related configuration information from the relay device or the remote UE, thereby improving flexibility and accuracy of obtaining the relay related configuration information by the UE.

The relay configuration method provided in the embodiment of the present application will be described below by way of specific embodiments (embodiment one to embodiment four).

Embodiment one: l2 architecture, remote UE is located outside the coverage of base station

Scheme one: remote UE has not yet been connected to the base station through relay UE:

at this time, the remote UE must find the relay UE through a procedure of discovery procedure and the like, and establish a connection, and wait for the subsequent base station to perform RRC radio resource configuration and related parameter configuration for the remote UE through the relay UE.

Scheme II: the remote UE connects to the base station through the relay UE:

since the remote UE and the base station have peer-to-peer RRC, SDAP, PDCP, and other protocol stacks, the base station performs RRC radio resource configuration and related parameter configuration for the remote UE through relay in the relay UE. The RRC radio resource configuration and the related parameter configuration may be sent by the base station to the relay UE in the form of a system message or in the form of RRC dedicated signaling, and then sent by the relay UE to the remote UE. And when the relay UE sends to the remote UE, the relay UE may also send to the remote UE in a broadcast, multicast or unicast manner.

Embodiment two: l2 architecture, remote UE located within base station coverage

At this time, if the remote UE has connected to the base station through the relay UE:

mode 1: the RRC radio resource configuration and the related parameter configuration of the remote UE are only sent from the base station to the relay UE and then forwarded to the remote UE by the relay UE, and the remote UE does not acquire the RRC radio resource configuration and the related parameter configuration from the base station through the Uu interface of the remote UE. For example, the remote UE may not initiate the RRC connection setup procedure at this time.

Mode 2: the RRC radio resource configuration and related parameter configuration of the remote UE are only sent from the base station directly to the remote UE over the Uu interface. At this time, there are two cases:

scheme 1. Remote UE may disconnect from relay UE. That is, at this time, the remote UE tends to communicate with the base station directly through the Uu interface, including not only the RRC radio resource configuration and related parameter configuration, but also data of the data plane.

Scheme 2. Remote UE may continue to connect to base station through relay UE, where RRC radio resource configuration and related parameter configuration of remote UE are only sent from base station to remote UE directly through Uu interface, and data of data plane of remote UE are transmitted between relay UE and base station.

Mode 3: the RRC radio resource configuration and the related parameter configuration of the remote UE may be obtained from the base station by sending the RRC radio resource configuration and the related parameter configuration to the relay UE and forwarding the RRC radio resource configuration and the related parameter configuration to the remote UE by the relay UE, or may be obtained from the base station through a Uu interface of the remote UE. At this point the base station itself can decide which way to send the configuration to the UE. At this time, there are two cases:

scheme 1: the data of the data plane of the remote UE can be transmitted between the remote UE and the base station through the relay UE, or can be transmitted between the remote UE and the base station through a Uu interface of the remote UE.

Scheme 2: data of the data plane of the remote UE is transmitted between the relay UE and the base station.

Mode 4: the remote UE determines which of the above modes 1-3 is adopted to implement the RRC radio resource configuration and related parameter configuration with the base station and the transmission of data plane data based on the indication of the base station (the indication may come from relay UE or from the remote own Uu interface).

Mode 5: the RRC radio resource configuration and related parameter configuration of the remote UE may be from relay UE or from direct Uu interface, depending on the specific content of the RRC radio resource configuration and related parameter configuration. For example, if the RRC radio resource configuration and related parameter configuration are for non-relay related traffic, then it comes from the Uu interface, and if they are for relay related traffic, then it comes from relay UE.

Mode 6: the RRC radio resource configuration of the remote UE and the related parameter configuration are from relay UE transfer or from direct Uu interface, and depend on the connection state of the remote UE and the base station, and the connection state of the remote UE and the base station through the relay UE. Such as:

1. if the remote UE has a direct RRC connection with the base station (e.g., an RRC connection setup is triggered due to a relay service or other service or cause, or a handover from a relay transfer link to a direct link is triggered), then the RRC radio resource configuration and related parameter configuration comes from the direct Uu interface.

2. If the remote UE has no direct RRC connection with the base station, but is directly connected to the base station through the relay UE, then there are two cases:

a. the RRC radio resource configuration and the related parameter configuration come from relay;

b. the dedicated RRC radio resource configuration and the related parameter configuration come from relay, and the remote UE may still read the system message of the base station to obtain the broadcasted RRC radio resource configuration and the related parameter configuration.

3. If the remote UE base station has no direct RRC connection, nor is it directly connected to the base station through the relay UE (e.g., there is no PC5-RRC connection between remote and relay, or the relay UE itself is in RRC-IDLE/INACTIVE state), then:

a. The remote UE can only read the system information of the base station through the Uu interface of the remote UE to obtain the broadcasted RRC radio resource configuration and related parameter configuration;

b. the remote UE can only obtain the broadcasted RRC radio resource configuration and related parameter configuration through the system message of the relay UE relay base station;

c. the remote UE may obtain the broadcasted RRC radio resource configuration and related parameter configuration by obtaining the system message of the base station either in a or b.

Embodiment III: l3 architecture, remote UE is located outside the coverage of base station

Scheme 1: remote UE has not yet been connected to the base station through relay UE:

the remote UE may use pre-configuration (factory pre-configuration or base station pre-configuration) at this point.

Scheme 2: the remote UE connects to the base station through the relay UE:

1. pre-configuration can only be used

2. Can be the same as case 2 in embodiment one

3. Either pre-configuration or case 2 in embodiment one may be used. Which may be indicated by the base station or the UE implementation or protocol convention is specifically used.

Embodiment four: l3 architecture, remote UE located within base station coverage

1. The relevant configuration is obtained based only on the remote UE's own Uu interface. Specifically, the RRC connection state determines whether to acquire a system message or a dedicated configuration (idle/active state uses a system message, and connected state uses a dedicated RRC radio resource configuration and related parameter configuration).

2. The relevant configuration is obtained in various ways in the above-described second embodiment.

The scheme of the application can be used for a UE-to-network relay architecture and a UE-to-UE relay architecture. (i.e., the base station in the above embodiment may be replaced with another remote UE). According to the scheme, the remote UE can accurately obtain the required RRC radio resource configuration and related parameter configuration under different architectures.
