Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so that embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

Some concepts and/or terms involved in the relay configuration method, apparatus, and user equipment provided by the embodiments of the present application are explained below.

1. Sidelink: It can also be called a side link or a side link. A sidelink is supported in a long term evolution (long term evolution, LTE) system, and the sidelink is used for direct data transmission between the UE and the UE without using a network device.

The design of LTE sidelink is suitable for specific public safety affairs (such as emergency communication in disaster sites such as fire or earthquake), or vehicle to everything (V2X) communication. Vehicle networking communication includes various services, such as basic safety communication, advanced (autonomous) driving, formation, sensor expansion, and so on. Since LTE sidelink only supports broadcast communication, it is mainly used for basic security communication. Other advanced V2X services with strict QoS requirements in terms of delay and reliability will be supported by NR sidelink.

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

2. 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, which is responsible for forwarding the wireless signal one or more times, that is, the wireless signal. It takes many hops to reach the terminal. Wireless relay technology can not only be used to expand cell coverage and make up for blind spots in cell coverage, but also improve cell capacity through spatial resource reuse. For indoor coverage, 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, wireless relay divides a base station-UE link into two links: base station-relay station and relay station-UE, so as to have the opportunity to replace one link with poor quality with two links. Links with better quality can obtain higher link capacity and better coverage. Currently, the relay supported in LTE is UE-to-network relay, that is, 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. 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. Usually the relay UE is open and can serve any remote UE.

It is worth noting that the technologies described in the embodiments of the present application are not limited to long term evolution (LTE)/LTE evolution (LTE-Advanced, LTE-A) systems, and can 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 (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used not only for the above-mentioned systems and radio technologies, but also for other systems and radio technologies. However, the following description describes a new radio (NR) system for example purposes, and uses NR terminology in most of the following description, these techniques are also applicable to applications other than NR system applications, such as 6th generation Generation, 6G) communication system.

The characteristics of the L2 architecture: the relay UE does not have a complete protocol stack for the data it relays, that is, except for the basic L2 transmission protocol stacks such as RLC, MAC and PHY, there are no corresponding protocol stacks such as RRC, SDAP and PDCP. RLC is used to carry and transmit the data of the remote UE. For the UE-to-network relay architecture, there are peer-to-peer protocol stacks such as RRC, SDAP, and PDCP between the remote UE and the base station, while there are only the RLC layer and the following protocol stacks between the remote UE and the relay UE.

In addition, when the UE receives the relay-related configuration information from the relay device, it can be understood that the relay-related configuration information may be directly sent by the relay device (that is, from the relay device itself), or the relay-related configuration information may be the relay device. Sent by the forwarding remote 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 the embodiment of the present application, the above-mentioned first indication information is used for the target device to indicate the sending method of the relay-related configuration information.

It should be noted that the sending method of the relay-related configuration information can 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 ( That is, the remote device sends it to the relay device, and the relay device sends it to the UE).

Optionally, in this embodiment of the present application, for the L2 architecture, the remote UE is located within the direct coverage of the base station. If the remote UE has been connected to the base station through the relay UE, the remote UE may be based on the base station's indication (that is, the first indication information). ) to determine from which device the relay-related configuration information and the transmission mode of the data plane data of the remote UE are received, that is, determine that the relay-related configuration information (and/or data plane data) comes from the Uu interface or the direct Uu interface of the remote UE.

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 predefined, pre-configured or protocol-stipulated relay-related configuration information according to the target information.

The relay UE performs RRC radio resource configuration and related parameter configuration for the remote UE.

Another example, for the L3 architecture, if the remote UE is located outside the coverage of the base station, and the remote UE has not been connected to the base station through the relay UE, the remote UE can use the preconfigured relay-related configuration information at this time.

Step 201g, when the UE is outside the direct coverage of the remote device and the UE is not connected to the remote device, the UE acquires predefined, pre-configured or protocol-stipulated relay-related configuration information.

Optionally, in this embodiment of the present application, the base station can send the relay-related configuration information to the relay UE, and then the relay UE forwards it to the remote UE, and the remote UE no longer obtains the relay-related configuration information from the base station through its own Uu interface. information. For example, at this time, the remote UE will not initiate the RRC connection establishment process due to relay communication; if a link switch is triggered and switched to the direct link with the base station, the subsequent relay-related configuration information can be directly obtained by the base station.

Step 503, the UE disconnects the connection with the relay device, and directly establishes a connection with the remote device.

It can be understood that when the UE is within 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, and then actively disconnects from the relay device. connection, and then send or receive the data plane data of the UE through the target device; and/or, the UE receives relay-related configuration information from the target device, and then actively establishes a connection with the remote device, and then sends or receives the data plane of the UE through the target device. data.

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

Step 201i, when the UE is within 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, and the system message includes the relay-related configuration information.

In the embodiment of this application, the relay-related configuration information of the remote UE comes from the relay device or the direct remote device, which depends on the direct connection state between the remote UE and the remote device, and how the remote UE communicates with the remote device through the relay device. The connection status of the device.

In one way, if the remote UE has a direct RRC connection with the remote device (for example, due to the relay service or other services/reasons, the establishment of the RRC connection is triggered, or the switching from the relay transit link to the direct link is triggered. ), then the relay-related configuration information comes from the direct remote device.

In another way, if the remote UE does not have a 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 by the relay device, or the UE can receive it from the relay device. Dedicated RRC radio resource configuration and related parameter configuration, and read the system message of the base station to obtain the broadcast RRC radio resource configuration and related parameter configuration.

In another way, if the remote UE does not have a direct RRC connection with the remote device, nor is it connected to the remote device through the relay device (for example, there is no PC5-RRC connection between the remote and the relay device, or the relay device In the RRC idle (idle) state or inactive (inactive) state), the remote UE can read the system message of the remote device through the Uu interface to obtain the broadcast RRC radio resource configuration and related parameter configuration, or the remote UE can pass The relay device relays the system message of the remote device to obtain the broadcasted RRC radio resource configuration and related parameter configuration.

Exemplarily, for the L3 architecture, the remote UE is located within the coverage of the base station, and the remote UE can obtain the RRC radio resource configuration and related parameter configuration from its own Uu interface. Specifically, the RRC connection state determines the acquisition of system messages or dedicated relay-related configuration information. For example, system messages are acquired in the idle state or inactive state, and dedicated RRC radio resource configuration and related parameter configurations are acquired in the connected state.

An embodiment of the present application provides a relay configuration method. The UE can obtain relay-related configuration information according to target information (whether the UE is within the direct coverage of the remote device, and/or whether the UE is connected to the remote device). . In the relay scenario, the UE can 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. Instead of directly receiving the relay-related configuration information from the relay device or the remote UE, the relay-related communication is used, thereby improving the flexibility and accuracy of the UE's acquisition of the relay-related configuration information.

The following describes the relay configuration method provided by the embodiment of the present application through specific embodiments (Embodiment 1 to Embodiment 4).

Embodiment 1: L2 architecture, the remote UE is located outside the coverage of the base station

Solution 1: The remote UE has not yet connected to the base station through the relay UE:

At this time, the remote UE must find the relay UE and establish a connection through the discovery procedure and other processes, and wait for the subsequent base station to configure the RRC radio resources and related parameters for the remote UE through the relay UE.

Option 2: The remote UE connects to the base station through the relay UE:

Since there are peer-to-peer RRC, SDAP, PDCP and other protocol stacks between the remote UE and the base station, the base station transfers through the relay UE at this time, and configures RRC radio resources and related parameters for the remote UE. The RRC radio resource configuration and related parameter configuration here can 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 is sent to the remote UE, it can also be sent to the remote UE by broadcast, multicast, or unicast.

Embodiment 2: L2 architecture, the remote UE is located within the coverage of the base station

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

Mode 1: The RRC radio resource configuration and related parameter configuration of the remote UE are only sent from the base station to the relay UE and then forwarded by the relay UE to the remote UE, and the remote UE no longer obtains the RRC radio resource configuration from the base station through its own Uu interface and related parameter configuration. For example, the remote UE may not initiate the RRC connection establishment process at this time.

Mode 2: The RRC radio resource configuration and related parameter configuration of the remote UE are only sent by the base station to the remote UE directly through the Uu interface. At this point, there are two situations:

Scenario 1: The remote UE may disconnect from the 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 the data on the data plane.

Scheme 2: The remote UE may continue to connect to the base station through the relay UE. At this time, the RRC radio resource configuration and related parameter configuration of the remote UE only come from the base station directly sent to the remote UE through the Uu interface, and the data of the remote UE data plane will pass through. relay transmits between the UE and the base station.

Mode 3: The RRC radio resource configuration and related parameter configuration of the remote UE can either be sent from the base station to the relay UE and then forwarded by the relay UE to the remote UE, or the RRC radio resource configuration and related parameters can be obtained from the base station through the remote Uu interface. related parameter configuration. At this time, the base station can decide which way to send the configuration to the UE by itself. At this point, there are two situations:

Option 1: The data on the data plane of the remote UE can either be relayed by the relay UE and transmitted to the base station, or it can be transmitted to the base station through its own Uu interface.

Scheme 2: The data on the data plane of the remote UE will be transmitted between the relay UE and the base station.

Mode 4: The remote UE is based on the base station's indication (the indication can come from relay UE relay, or from the remote's own Uu interface) to determine which of the above Modes 1 to 3 is used to achieve communication with the base station. RRC radio resource configuration and related parameter configuration and data plane data transmission.

Mode 5: The RRC radio resource configuration and related parameter configuration of the remote UE comes from relay UE relay or from the 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 used for non-relay-related services, they come from the Uu interface, and if they are used for relay-related services, they come from relay UE transit.

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

1. If the remote UE has a direct RRC connection with the base station (for example, the establishment of the RRC connection is triggered by the relay service or other services or reasons, or the handover from the relay relay link to the direct link is triggered), then the RRC radio resources Configuration and related parameter configuration comes from the direct Uu interface.

2. If the remote UE does not have a direct RRC connection with the base station, but is directly connected to the base station through the relay UE, there are two cases:

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

b. The dedicated RRC radio resource configuration and related parameter configuration come from relay relay, and the remote UE can still read the system message of the base station to obtain the broadcasted RRC radio resource configuration and 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, there is no PC5-RRC connection between the remote and the relay, or the relay UE itself is in the RRC-IDLE/INACTIVE state), then:

a. The remote UE can only read the system message of the base station through its own Uu interface 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 can obtain the broadcasted RRC radio resource configuration and related parameter configuration by obtaining the system information of the base station in either a or b.

Embodiment 3: L3 architecture, the remote UE is located outside the coverage of the base station

Scenario 1: The remote UE has not yet connected to the base station through the relay UE:

At this time, the remote UE can use pre-configuration (factory pre-configuration or base station pre-configuration).

Option 2: The remote UE connects to the base station through the relay UE:

1. Only pre-configured

2. It can be the same as case 2 in Example 1

3. You can use pre-configured or the same as case 2 in Example 1. Which one to use can be indicated by the base station or implemented by the UE or agreed in a protocol.

Embodiment 4: L3 architecture, the remote UE is located within the coverage of the base station

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

2. Use the various methods in the second embodiment to obtain the relevant configuration.

The solution of this application can be used for both UE-to-network relay architecture and UE-to-UE relay architecture. (That is, the base station in the above embodiment can be replaced with another remote UE). Through the solution of the present application, the remote UE can accurately obtain the required RRC radio resource configuration and related parameter configuration under different architectures.
