Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

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

1. Sidelink (sidelink): which may also be referred to as side links or side links, etc. In a Long Term Evolution (LTE) system, sidelink is supported, and is used for data transmission between UEs without passing through a network device.

The design of LTE sidelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes), or vehicle to internet (V2X) communication, etc. The internet of vehicles communication includes various services, such as basic security type communication, advanced (automated) driving, formation, sensor expansion, and the like. Since LTE sidelink supports only broadcast communication, and is therefore mainly used for basic security class communication, 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 an operating frequency band above 6GHz which is not supported by LTE, and supports a larger operating bandwidth, but the current version of the NR system only supports an interface between a base station and a terminal, and does not support a sidelink interface for direct communication between terminals. The sidelink link interface may be referred to as a PC5 interface.

2. Relay (relay) mechanism: in the relay technology in the wireless communication system, one or more relay nodes are added between a base station and a terminal and are responsible for forwarding wireless signals once or many times, that is, the wireless signals can reach the terminal through multiple hops. The wireless relay technology can be used for expanding cell coverage, making up cell coverage blind spots, and simultaneously improving cell capacity through spatial resource multiplexing. For indoor coverage, the relay technology can also play a role in overcoming the penetration loss and improving the indoor coverage quality. For example, in the case of two-hop relay, the wireless relay divides a base station-UE link into two links, i.e., a base station-relay and a relay station-UE, so that there is an opportunity to replace a link with poor quality with two links with better quality, thereby obtaining higher link capacity and better coverage. Currently, the relay supported in LTE is a UE-to-network relay, i.e., one end of the relay is connected to the UE and the other end is connected to the network side. The UE connected to the relay is called a remote UE (remote). 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 the embodiments of the present application are not limited to the Long Term Evolution (LTE)/LTE evolution (LTE-Advanced) system, but may also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single-carrier frequency-division multiple access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for purposes of example, and the NR terminology is used in much of the description below, and the techniques may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

Fig. 1 illustrates an architecture diagram 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, the UE 01 and the network device 02 can establish connection and communicate.

The UE in this embodiment may also be referred to as a terminal device, where the UE may be a mobile phone, a tablet personal computer (tablet personal computer), a laptop computer (laptop computer) or a terminal-side device called a notebook computer, a Personal Digital Assistant (PDA), a palm top computer, a netbook, an ultra-mobile personal computer (UMPC), a Mobile Internet Device (MID), a wearable device (wearable device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), and the wearable device includes: bracelets, earphones, glasses and the like. It should be noted that the embodiment of the present application does not limit the specific type of the UE.

The network device in the embodiment 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 (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an 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 Transmit Receive Point (TRP), or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment 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 embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

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

Among them, the L3 architecture is characterized in that: the relay UE has a complete protocol stack, that is, in addition to a basic L2 transport protocol stack of a radio link layer control protocol (RLC), a medium access control sublayer protocol (MAC), and a physical layer Protocol (PHY), the relay UE also has protocol stacks of a Radio Resource Control (RRC), a Service Data Adaptation Protocol (SDAP), and a Packet Data Convergence Protocol (PDCP), and is configured to carry and transmit data of the relay UE. For the UE-to-UE relay architecture, a complete protocol stack is arranged between the relay UE1 and the relay UE, and a complete protocol stack is also arranged between the relay UE and the relay UE 2; for the UE-to-network relay architecture, a complete protocol stack is arranged between remote UE and relay UE, and a complete protocol stack is also arranged between the relay UE and a base station.

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

In addition, no matter the L2 architecture, the L3 architecture, or the UE-to-network relay, the UE-to-UE relay, an additional adaptation layer (adaptation layer) may be further provided at the remote UE, the relay UE, and the base station, and the embodiment of the present application does not limit the protocol stack.

An embodiment of the present application provides a method for configuring a relay, and fig. 2 shows a flowchart of the method for configuring the 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

steps

201 and 202 described below.

Step 201, the UE acquires target information.

Step 202, the UE obtains the relevant configuration information of the relay according to the target information.

In an embodiment of the present application, the target information includes at least one of: the first information is used for indicating whether the UE is in a direct coverage range of the remote equipment, the second information is used for indicating whether the UE is connected with the remote equipment, the relay related configuration information is used for the UE to carry out relay related communication, and the remote equipment is the remote UE or network equipment of the UE.

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

Optionally, in this 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 a MAC CE, or may also be preconfigured.

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

Optionally, in this embodiment of the application, the step 201 may be specifically implemented by the following step 201a, step 201b, or step 201 c.

Step 201a, the UE receives the 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: a relay device and a remote device.

It should be noted that, in this embodiment of the present application, the receiving, by the UE, 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 only receive the relay-related configuration information from the relay device and cannot receive the relay-related configuration information from the remote device; alternatively, the UE may only receive relay-related configuration information from the remote device and may not be able to receive relay-related configuration information from the relay device; or, the UE may receive the relay-related configuration information from both the relay device and the remote device, but the actual relay-related configuration information in each configuration receiving process only comes from the relay device or only comes from the remote device; alternatively, the UE may receive the relay-related configuration information from both the relay device and the remote device, and the relay device and the remote device may receive the configuration-related configuration information from both the relay device and the remote device at the same time each time the configuration is received. In addition, the UE receiving the relay related configuration information from the relay device may 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 the remote device forwarded by the relay device.

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

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

The transmission method of the relay related configuration information may be understood as follows: the relay related configuration information is directly transmitted by the remote device, or directly transmitted by the relay device, or forwarded by the relay device (i.e. the remote device transmits to the relay device, and the relay device transmits to the UE).

Optionally, in this embodiment of the present application, for an L2 architecture, the remote UE is located within a direct coverage 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 an indication (i.e., the first indication information) of the base station, from which device to receive the relay-related configuration information and a transmission manner of 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 of the remote UE directly or is relayed through the relay.

The first indication information may be transmitted by the target device, the relay-related configuration information may be transmitted by the target device, and the device that transmits the first indication information may be the same as or different from the device that transmits the relay-related configuration information. For example, the first indication information may be sent by the remote device to the UE to indicate the UE to receive the relay-related configuration information from the relay device. Alternatively, the first indication information may be sent by the relay device to the UE to indicate the UE to receive the relay-related configuration information from the remote device.

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

It should be noted that, for a specific method for the UE to receive the relay related configuration information sent by the target device, or to obtain the predefined, preconfigured, or protocol agreed relay related configuration information, the following embodiments are described, and details are not repeated here.

Optionally, in an implementation manner of the embodiment of the present application, the step 201 may be specifically implemented by a step 201d or a step 201e described below.

Step 201d, when the UE is outside 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 relay device.

Step 201e, under the condition 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 obtains the relay related configuration information predefined, preconfigured or agreed by the protocol.

Optionally, in this embodiment of the present application, an obtaining manner of the relay related configuration information is determined by any one of: second indication information, UE and protocol conventions. And 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, 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, whether the UE executes the step 201d or the step 201e may be determined by the second indication information, 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 of the base station and the remote UE is connected to the base station through the remote UE, since peer RRC, SDAP, PDCP, and other protocol stacks are provided between the remote UE and the base station, the base station may transfer the remote UE to perform RRC radio resource configuration and related parameter configuration for the remote UE. The RRC radio resource configuration and the related parameter configuration may be that the base station sends the relay UE in the form of a system message, and then the relay UE sends the system message to the remote UE, or sends the system message to the relay UE in the form of an RRC dedicated signaling, and then the relay UE sends the system message to the remote UE. When sending to the remote UE, the relay UE may send to the remote UE in a broadcast, multicast or unicast manner.

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

Optionally, in another implementation manner of the embodiment of the present application, the step 201 may be specifically implemented by a step 201f or a step 201g described below.

Step 201f, in the case that the UE is outside the direct coverage of the remote device and the UE is not connected to the remote device, after the UE establishes connection with the relay device, the UE receives the relay related configuration information sent by the relay device.

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

For another example, for the L3 architecture, if a remote UE is located outside the coverage of the base station and the remote UE has not connected to the base station through a relay UE, the remote UE may use the preconfigured relay-related configuration information.

Step 201g, under the condition that the UE is out of the direct coverage of the remote device and the UE is not connected to the remote device, the UE obtains predefined, preconfigured or protocol agreed relay related configuration information.

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

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

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

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

Optionally, in another implementation manner of the embodiment of the present application, the step 201 may be specifically implemented by a step 201h described below.

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

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

Step 301, the UE disconnects from the relay device.

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

Step 303, 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 may actively disconnect from the relay device, and then receive the relay-related configuration information from the target device; and/or the UE may initially 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 and the relay device cannot perform unicast or dedicated connection for transmitting and receiving data (for example, relay-related configuration information and/or data plane data) therebetween, but the UE may also perform data transmission via the relay device when the relay device and the UE support transmission and reception of data in a multicast or broadcast format.

Optionally, in this embodiment of the application, the "UE receives the relay-related configuration information sent by the target device" in the step 201h may specifically be implemented in the step 201h1 or the 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, when 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 is understood that the relay-related configuration information of the remote UE is from relay UE relay or from the Uu interface directly (i.e. directly received 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 relayed from a relay UE.

Optionally, in this embodiment of the application, the "UE receives the relay-related configuration information sent by the target device" in the step 201h may specifically be 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 the relay related configuration information.

Optionally, in this 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 this embodiment of the present application, after the step 201h, the method for configuring a relay 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 sending or receiving data plane data of the UE through the target device may be understood as: the UE sends 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 be from the same link (direct Uu interface or Relay) or 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; or, the UE may receive the relay-related configuration information from the relay device, and send or receive data plane data through the remote device; or, the UE may receive the relay-related configuration information from the remote device, and send or receive data plane data through the remote device; alternatively, the UE may receive relay-related configuration information from the remote device and send or receive data plane data via the relay device.

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

Step 401a, when 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, under the condition that the UE directly establishes connection with the remote device, the UE sends or receives data plane data of the UE through the target device.

Step 401c, under the condition 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 performing step 301 (or step 302 or step 303), the UE may perform "the UE receives the relay-related configuration information sent by the target device" and step 401 in step 201h, that is, 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 may actively disconnect from 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.

For example, in a 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 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 the relay-related configuration information from the base station and transmit data plane data with the base station.

For another example, in a 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 be connected to the base station through the relay UE, and at this time, 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.

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

Step 501, the UE disconnects with the relay device.

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

Step 503, the UE disconnects from the relay device and directly establishes 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 the relay-related configuration information from the target device, then actively disconnects the relay device, and 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 of the data plane of the UE through the target equipment.

Optionally, in another implementation manner of the embodiment of the present application, the step 201 may be specifically implemented by a step 201i described below.

Step 201i, under the condition that 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 this embodiment of the present application, the relay related configuration information of the remote UE comes from relay equipment or direct remote equipment, and depends on a direct connection state between the remote UE and the remote equipment and a connection state between the remote UE and the remote equipment through the relay equipment.

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

In another mode, 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 relayed 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 mode, if the remote UE has no direct RRC connection with the remote device, or is not connected to the remote device through the relay device (for example, there is no PC5-RRC connection between the remote UE and the relay device, or the relay device is in an RRC idle (idle) state or an inactive (inactive) state), the remote UE may read a system message of the remote device through a Uu interface to obtain the broadcasted RRC radio resource configuration and related parameter configuration, or the remote UE may transfer the system message of the remote device through the relay device to obtain the broadcasted RRC radio resource configuration and related parameter configuration.

For example, for the L3 architecture, a remote UE is located in the coverage 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 the system message or the dedicated relay related configuration information, for example, the system message is acquired in idle state or inactive state, and the dedicated RRC radio resource configuration and related parameter configuration are acquired in connected (connected) state.

The embodiment of the present application provides a relay configuration method, where a UE may obtain 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 to the remote device). In a 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 the flexibility and accuracy of the UE in obtaining the relay related configuration information.

The following describes a relay configuration method provided in an embodiment of the present application with reference to specific embodiments (embodiment one to embodiment four).

The first embodiment is as follows: l2 architecture, remote UE located outside base station coverage

The first scheme is as follows: the remote UE has not connected to the base station through the relay UE:

at this time, the remote UE must find the relay UE through the discovery process 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 is connected to the base station through the relay UE:

because the remote UE and the base station have 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 UE transfer. The RRC radio resource configuration and 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. 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.

Example two: l2 architecture, remote UE located in 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 to the remote UE by the base station and then forwarded to the remote UE by the remote UE, and the remote UE does not obtain the RRC radio resource configuration and the related parameter configuration from the base station through a Uu interface of the remote UE. For example, at this time, the remote UE may not initiate the RRC connection establishment procedure.

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

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

In the scheme 2, the remote UE may continue to be connected to the base station through the remote UE, at this time, the RRC radio resource configuration and the related parameter configuration of the remote UE only come from the base station and are directly sent to the remote UE through a Uu interface, and data of a data plane of the remote UE is transmitted between the remote UE and the base station.

Mode 3: the RRC radio resource configuration and the related parameter configuration of the remote UE may be sent from the base station to the relay UE and then forwarded to the remote UE, or may be obtained from the base station through a Uu interface of the remote UE. The base station may decide at this point on its own from which route to configure to the UE. At this time, two cases are divided:

scheme 1: the data of the data plane of the remote UE can be transmitted between the base station through relay UE, or transmitted with the base station through the 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, based on the indication from the base station, (the indication may be from relay UE relay or from the remote UE Uu interface), which specific manner is adopted in the above manner 1-manner 3 to implement RRC radio resource configuration and related parameter configuration with the base station and data plane data transmission.

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

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

1. if the remote UE has a direct RRC connection with the base station (e.g. RRC connection establishment is triggered due to relay service or other services or reasons, or handover from a relay link to a direct link is triggered), the RRC radio resource configuration and related parameter configuration come from a direct Uu interface.

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

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

b. the dedicated RRC radio resource configuration and the related parameter configuration are from relay, and the remote UE can 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 and is not directly connected to the base station through the relay UE (for example, no PC5-RRC connection exists between the remote and the relay, or the relay UE is in an RRC-IDLE/INACTIVE state by itself), then:

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

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

c. the remote UE can obtain the system message of the base station in a manner of a or b to obtain the broadcasted RRC radio resource configuration and related parameter configuration.

Example three: l3 architecture, remote UE located outside base station coverage

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

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

Scheme 2: the remote UE is connected to the base station through the relay UE:

1. only using preconfiguration

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

3. Either pre-configuration may be used or case 2 in the first embodiment may be used. Which may be indicated by the base station or implemented by the UE or agreed upon by the protocol is specifically used.

Example four: l3 architecture, remote UE located in base station coverage

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

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

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