[0004] Relay technology in wireless communication systems involves adding one or more relay devices between network equipment (e.g., base stations) and terminals to forward wireless signals once or multiple times. For example, when the link quality between a remote user equipment (UE) and a network device deteriorates, the remote UE can select a suitable relay UE to ensure service continuity through UE-to-network (U2N) relay technology. The remote UE may also be referred to as a remote terminal or remote terminal.

[0042] The cell configuration method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] Please refer to FIG. 2 , which is a flowchart of a cell configuration method provided in an embodiment of the present application. The method can be performed by a relay device, as shown in FIG. 2 , including the following steps:

[0044] Step 201: A relay device receives a first request message sent by a first terminal, where the first request message is used to request a network device to configure an Scell ​​for the first terminal.

[0045] In this embodiment, the first request message is used to request the network device to configure an Scell ​​for the first terminal. This may also be referred to as the first request message being used to request adding a Scell, configuring a CA, or adding a CA, etc., for the first terminal. That is, in this embodiment, configuring a Scell ​​may also be referred to as adding a Scell, configuring a CA, or adding a CA, etc.

[0046] In some optional embodiments, the first request message may include a cell measurement report, for example, the first request message may include an A4 measurement report of the cell. In addition, the first request message may be a Radio Resource Control (RRC) message.

[0047] In some optional embodiments, the first request message may include CA information of the relay device, where the CA information includes information of the Scell ​​added by the relay device.

[0048] It can be understood that before the relay device receives the first request message sent by the first terminal, a communication connection is established between the first terminal and the relay device.

[0049] Step 202: The relay device sends a second request message to the network device, wherein the second request message is determined according to the first request message.

[0050] Exemplarily, the second request message may be the same as the first request message, that is, the relay device merely forwards the first request message received from the first terminal to the network device; or, the second request message may be a newly generated request message based on the first request message. For example, the relay device may insert the information of the Scell ​​added by the relay device into the first request message, and send the first request message after inserting the information of the Scell ​​added by the relay device to the network device, wherein the second request message is the first request message after inserting the information of the Scell ​​added by the relay device.

[0051] The following situations are explained:

[0052] Case 1: The first terminal adds the relay device's CA information. That is, the first request message includes the relay device's CA information, and the second request message also includes the relay device's CA information. The CA information included in the second request message is the same as the CA information included in the first request message. In this case, upon receiving the first request message, the relay device can directly forward the relay device's CA information included in the first request message to the network device.

[0053] Case 2: The relay device adds its CA information. Specifically, the first request message may not include the relay device's CA information, while the second request message includes it. In this case, upon receiving the first request message, the relay device may insert the relay device's CA information into the first request message and send the first request message containing the relay device's CA information to the network device. The second request message is the first request message containing the relay device's CA information.

[0054] Case three: The network device obtains the CA information of the relay device locally, that is, the above-mentioned first request message may not include the CA information of the relay device, and the above-mentioned second request message may not include the CA information of the relay device. When the network device receives the second request message, it obtains the CA information of the relay device locally.

[0055] It can be understood that, when the network device receives the second request message, it can configure the Scell ​​for the first terminal. For example, when the above-mentioned second request message includes the information of the Scell ​​added by the relay device, the network device can configure the Scell ​​added by the relay device to the first terminal; when the above-mentioned second request message does not include the information of the Scell ​​added by the relay device, the network device can locally search for the information of the Scell ​​added by the relay device, and then configure the Scell ​​added by the relay device to the first terminal.

[0056] Step 203: The relay device receives Scell ​​configuration information sent by the network device, wherein the Scell ​​configuration information is used to configure a Scell ​​for the first terminal, and the Scell ​​configuration information includes information of the Scell ​​added by the relay device.

[0057] In this embodiment, the Scell ​​configuration information may include information about at least one Scell, including information about the Scell ​​added by the relay device. That is, the network device may configure at least one Scell ​​for the first terminal, including the Scell ​​added by the relay device. The Scell ​​information may include, but is not limited to, at least one of a Scell ​​identifier (i.e., a Scell ​​ID), a Scell ​​bandwidth, and a Scell ​​frequency.

[0058] Step 204: The relay device sends the Scell ​​configuration information to the first terminal.

[0059] In this step, the relay device may forward the Scell ​​configuration information received from the network device to the first terminal, and the first terminal may activate the Scell ​​based on the Scell ​​configuration information. For example, if the Scell ​​configuration information includes information about one Scell, the first terminal may activate the Scell; if the Scell ​​configuration information includes information about at least two Scells, the first terminal may activate at least one of the at least two Scells.

[0060] The cell configuration method provided in an embodiment of the present application is as follows: a relay device receives a first request message sent by a first terminal, wherein the first request message is used to request a network device to configure an Scell ​​for the first terminal; sends a second request message to the network device, wherein the second request message is determined based on the first request message; receives Scell ​​configuration information sent by the network device, wherein the Scell ​​configuration information is used to configure an Scell ​​for the first terminal, and the Scell ​​configuration information includes information of the Scell ​​added by the relay device; and sends the Scell ​​configuration information to the first terminal, that is, the embodiment of the present application configures the information of the Scell ​​added by the relay device to the first terminal when configuring the Scell ​​for the first terminal, which is conducive to ensuring the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal, thereby reducing the occurrence of a mismatch between the transmission rate of the first terminal and the transmission rate of the relay device, thereby ensuring the transmission rate of the first terminal.

[0061] Optionally, the second request message includes CA information of the relay device, and the CA information includes information of the Scell ​​added by the relay device.

[0062] In this embodiment, the second request message sent by the relay device to the network device includes the CA information of the relay device, wherein the CA information includes information of the Scell ​​added by the relay device. In some optional embodiments, the CA information may also include information of the primary cell (PCell) of the relay device.

[0063] Exemplarily, the first terminal may include the CA information of the relay device in the first request message, in which case the CA information of the relay device included in the second request message may be the same as the CA information of the relay device included in the first request message; or, the relay device may add the CA information of the relay device to the received first request message, in which case the second request message may be the first request message after the CA information of the relay device is added.

[0064] In this embodiment, the second request message sent to the network device includes the CA information of the relay device, so that the network device can directly configure the Scell ​​for the first terminal based on the CA information of the relay device included in the second request message. This can ensure the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal while reducing the operation of the network device.

[0065] Optionally, before the relay device sends the second request message to the network device, the method further includes:

[0066] The relay device generates a second request message according to the first request message and the CA information of the relay device.

[0067] In this embodiment, when the relay device receives the first request message, it can add the CA information of the relay device to the first request message to obtain a second request message, that is, the second request message is the first request message after adding the CA information of the relay device, and then the relay device can send the second request message to the network device.

[0068] It should be noted that the CA information of the relay device may change in some scenarios. For example, the Scell ​​added by the relay device may change when the relay device moves. Therefore, the relay device adds the CA information of the relay device in the first request message, which is conducive to ensuring that the added CA information is the current CA information of the relay device. This can reduce the occurrence of inconsistencies between the Scell ​​added by the relay device and the Scell ​​added by the first terminal due to changes in the CA information of the relay device.

[0069] In some optional embodiments, when the relay device currently has not added or configured Scell ​​or CA, the relay device may directly forward the first request message to the network device upon receiving the first request message. In this case, the network device may configure the Scell ​​for the first terminal according to the Scell ​​configuration method of the prior art. For example, the Scell ​​may be configured for the first terminal based on the measurement report of the cell reported by the first terminal.

[0070] Optionally, the relay device generates a second request message according to the first request message and the CA information of the relay device, including:

[0071] When a first condition is satisfied between the relay device and the first terminal, the relay device generates a second request message according to the first request message and the current CA information of the relay device;

[0072] The first condition includes any one of the following:

[0073] The first SIM card and the second SIM card belong to the same operator;

[0074] The first operator of the first SIM card is different from the second operator of the second SIM card, and the networks of the first operator and the second operator support inter-network roaming;

[0075] The first SIM card is a SIM card used by the relay device to connect to the network, and the second SIM card is a SIM card used by the first terminal to connect to the network.

[0076] It should be noted that when the first condition is not met between the relay device and the first terminal, the relay device can directly forward the first request message to the network device. In this case, the network device can configure the Scell ​​for the first terminal according to the Scell ​​configuration method of the existing technology. For example, the Scell ​​can be configured for the first terminal based on the measurement report of the cell reported by the first terminal.

[0077] In this embodiment, when the first condition is met between the relay device and the first terminal, the relay device generates a second request message based on the first request message and the current CA information of the relay device. This can reduce the occurrence of failures in adding secondary cells for the first terminal due to the operator network used by the first terminal and the relay device, which is conducive to improving the efficiency of adding secondary cells for the first terminal.

[0078] Optionally, before the relay device receives the first request message sent by the first terminal, the method further includes:

[0079] The relay device receives a query request sent by the first terminal, wherein the query request is used to request CA information of the relay device;

[0080] The relay device sends query response information to the first terminal, wherein the query response information includes CA information of the relay device.

[0081] Exemplarily, the first terminal may send a query request to the relay device when determining that a secondary cell needs to be added, and the relay device may send the current CA information of the relay device to the first terminal in response to the query request; or, during the time period when the relay device and the first terminal are in a communication connection state, the relay device may synchronize its CA information to the first terminal. For example, the first terminal may send a query request to the relay device at preset time intervals, and the relay device may send the current CA information of the relay device to the first terminal in response to the query request, wherein the above-mentioned preset time length may be reasonably set according to actual needs, for example, 1 minute or 5 minutes, etc.

[0082] It should be noted that, when the first terminal receives the CA information of the relay device, it may store the CA information of the relay device or send the CA information of the relay device to the network device.

[0083] In this embodiment, the relay device synchronizes its CA information to the first terminal, which makes it convenient for the first terminal to configure or add a secondary cell based on the CA information of the relay device. For example, a secondary cell configuration request, i.e., a first request message, is sent to the network device according to the CA information of the relay device, or a secondary cell is added according to the CA information of the relay device when the network device fails to configure a secondary cell for the first terminal, etc., which is conducive to ensuring the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal.

[0084] Optionally, the first request message includes CA information of the relay device, the second request message includes CA information of the relay device, and the CA information of the relay device included in the second request message is the same as the CA information of the relay device included in the first request message.

[0085] Exemplarily, when the first terminal obtains the CA information of the relay device, it may add the CA information of the relay device to the first request message. When the relay device receives the first request message, it may forward the CA information of the relay device included in the first request message to the network device. In this case, the second request message may be a message forwarded by the relay device to the network device, which includes the CA information of the relay device included in the first request message.

[0086] In this embodiment, the first terminal adds the CA information of the relay device in the first request message. In this case, the relay device can directly forward the CA information of the relay device included in the first request message to the network device, which can simplify the processing flow of the relay device. In addition, since existing relay devices are often only used for message forwarding, this is also conducive to reducing changes to the processing flow of the relay device.

[0087] Please refer to FIG3 , which is a flowchart of a cell configuration method provided in an embodiment of the present application. The method can be performed by a first terminal, as shown in FIG3 , including the following steps:

[0088] Step 301: A first terminal sends a first request message to a relay device, wherein the first request message is used to request a network device to configure an Scell ​​for the first terminal.

[0089] In this embodiment, the first terminal may send a first request message to the relay device when determining that a Scell ​​needs to be added based on a service status. For example, when the first terminal needs to perform a service that requires a high network rate, the first terminal sends the first request message to the relay device to request the network device to configure a Scell ​​for the first terminal. The services that require a high network rate include, for example, live streaming, video streaming, and gaming.

[0090] Among them, the first request message of this embodiment can refer to the relevant description of the above embodiment, and will not be repeated here.

[0091] It can be understood that, before sending the first request message to the relay device, the first terminal has already established a communication connection with the primary cell and has already established a communication connection with the relay device.

[0092] Step 302: The first terminal receives Scell ​​configuration information sent by the relay device, wherein the Scell ​​configuration information is used to configure a Scell ​​for the first terminal, and the Scell ​​configuration information includes information of the Scell ​​added by the relay device.

[0093] For the Scell ​​configuration information of this embodiment, reference may be made to the relevant descriptions of the aforementioned embodiments, which will not be elaborated here.

[0094] Step 303: The first terminal activates the Scell ​​configured by the Scell ​​configuration information.

[0095] Exemplarily, when the Scell ​​configuration information includes information about one Scell, the first terminal may activate the Scell, i.e., the Scell ​​added by the relay device; when the Scell ​​configuration information includes information about at least two Scells, the first terminal may activate at least one of the at least two Scells, for example, activate the Scell ​​added by the relay device.

[0096] In this embodiment, since the Scell ​​configuration information includes the information of the Scell ​​added by the relay device, that is, when the Scell ​​is configured for the first terminal, the information of the Scell ​​added by the relay device is configured to the first terminal, this is conducive to ensuring the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal, thereby reducing the occurrence of mismatch between the transmission rate of the first terminal and the transmission rate of the relay device, thereby ensuring the transmission rate of the first terminal.

[0097] Optionally, before the first terminal sends the first request message to the relay device, the method further includes:

[0098] The first terminal sends a query request to the relay device, wherein the query request is used to request carrier aggregation CA information of the relay device, and the CA information includes information of the Scell ​​added by the relay device;

[0099] The first terminal receives the query response information sent by the relay device, wherein the query response information includes the CA information of the relay device;

[0100] The first terminal stores the CA information of the relay device.

[0101] Exemplarily, the first terminal may send a query request to the relay device when determining that a secondary cell needs to be added, and the relay device may send the current CA information of the relay device to the first terminal in response to the query request; or, during the time period when the relay device and the first terminal are in a communication connection state, the relay device may synchronize its CA information to the first terminal. For example, the first terminal may send a query request to the relay device at preset time intervals, and the relay device may send the current CA information of the relay device to the first terminal in response to the query request, wherein the above-mentioned preset time length may be reasonably set according to actual needs, for example, 1 minute or 5 minutes, etc.

[0102] In this embodiment, the first terminal obtains and stores the CA information of the relay device, which makes it convenient for the first terminal to configure or add a secondary cell based on the CA information of the relay device. For example, a secondary cell configuration request, i.e., a first request message, is sent to the network device according to the CA information of the relay device, or a secondary cell is added according to the CA information of the relay device when the network device fails to configure the secondary cell for the first terminal, etc., which is conducive to ensuring the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal.

[0103] Optionally, the first request message includes CA information of the relay device.

[0104] Exemplarily, when the first terminal obtains the CA information of the relay device, it can add the CA information of the relay device in the first request message, so that when the relay device receives the first request message, it can forward the CA information of the relay device included in the first request message to the network device.

[0105] In this embodiment, the first terminal adds the CA information of the relay device in the first request message. In this case, the relay device can directly forward the CA information of the relay device included in the first request message to the network device, which can simplify the processing flow of the relay device. In addition, since existing relay devices are often only used for message forwarding, this is also conducive to reducing changes to the processing flow of the relay device.

[0106] Optionally, the method further includes: when the first terminal fails to receive the Scell ​​configuration information sent by the relay device, the first terminal activating the Scell ​​according to the stored CA information of the relay device.

[0107] In this embodiment, when the first terminal fails to successfully receive the Scell ​​configuration information, for example, the failure to receive the Scell ​​configuration information is caused by poor network quality, the first terminal can obtain the stored CA information of the relay device, obtain the information of the Scell ​​added by the relay device from the CA information of the relay device, and activate the Scell ​​added by the relay device, that is, the Scell ​​added by the relay device is also used as the Scell ​​of the first terminal. This can reduce the occurrence of failure to add the Scell ​​to the first terminal due to the failure to receive the Scell ​​configuration information, which is beneficial to ensuring the transmission rate of the first terminal.

[0108] In some optional embodiments, after activating the Scell, the first terminal may send feedback information to the network device to indicate the activated Scell ​​to the network device, so as to ensure consistency in understanding between the first terminal and the network device.

[0109] Please refer to FIG4 , which is a flowchart of a cell configuration method provided in an embodiment of the present application. The method can be executed by a network device, as shown in FIG4 , including the following steps:

[0110] Step 401: A network device receives a second request message sent by a relay device, wherein the second request message is used to request the network device to configure an Scell ​​for a first terminal.

[0111] It should be noted that, for the second request message of this embodiment, reference can be made to the relevant description of the aforementioned embodiment, which will not be elaborated here.

[0112] Step 402: The network device sends Scell ​​configuration information to the relay device, where the Scell ​​configuration information is used to configure a Scell ​​for the first terminal, and the Scell ​​configuration information includes information of the Scell ​​added by the relay device.

[0113] In this embodiment, when the network device receives the second request message, it can configure the Scell ​​for the first terminal. For example, when the above-mentioned second request message includes the information of the Scell ​​added by the relay device, the network device can configure the Scell ​​added by the relay device to the first terminal; when the above-mentioned second request message does not include the information of the Scell ​​added by the relay device, the network device can locally search for the information of the Scell ​​added by the relay device, and then configure the Scell ​​added by the relay device to the first terminal.

[0114] It should be noted that when the network device configures the Scell ​​for the first terminal, in addition to considering the information of the Scell ​​added by the relay device, it also needs to consider factors such as the signal quality of the cell and the capabilities of the terminal. For example, when the signal quality of the Scell ​​added by the relay device meets the threshold requirement, the Scell ​​added by the relay device can be preferentially configured for the first terminal. When the signal quality of the Scell ​​added by the relay device does not meet the threshold requirement, the network device may not configure the Scell ​​added by the relay device for the first terminal.

[0115] In this embodiment, since the Scell ​​configuration information includes the information of the Scell ​​added by the relay device, that is, when the Scell ​​is configured for the first terminal, the information of the Scell ​​added by the relay device is configured to the first terminal, this is conducive to ensuring the consistency of the Scell ​​added by the relay device and the Scell ​​added by the first terminal, thereby reducing the occurrence of mismatch between the transmission rate of the first terminal and the transmission rate of the relay device, thereby ensuring the transmission rate of the first terminal.

[0116] Optionally, the second request message includes CA information of the relay device, and the CA information includes information of the Scell ​​added by the relay device.

[0117] It should be noted that the implementation of this embodiment can refer to the relevant description of the embodiment shown in Figure 2, and will not be described in detail here.

[0118] Optionally, after the network device receives the second request message sent by the relay device, the method further includes:

[0119] The network device obtains information of the Scell ​​added by the relay device;

[0120] The network device determines the Scell ​​configuration information according to the information of the Scell ​​added by the relay device.

[0121] For example, when the second request message does not carry the CA information of the relay device, the network device can search for the CA information of the relay device locally, and then configure the Scell ​​information in the CA information of the relay device to the first terminal, that is, the Scell ​​information added by the relay device is included in the Scell ​​configuration information.

[0122] In this embodiment, the network device determines information of the Scell ​​added by the relay device and configures it to the first terminal. This not only ensures that the Scell ​​configured for the first terminal is the current Scell ​​of the relay device, but also saves signaling overhead.

[0123] The following examples illustrate the embodiments of the present application:

[0124] As shown in FIG5 , the cell configuration method provided in the embodiment of the present application includes the following steps:

[0125] Step 501: A first terminal inserts a SIM card and performs communication services after logging on to a network.

[0126] In this step, the first terminal selects a cell in the CA cell set to access, completes the network attachment process on the Pcell, and establishes an initial connection. The Pcell is the cell where the first terminal resides, that is, the primary serving cell of the first terminal, which is responsible for RRC communication with the first terminal.

[0127] It should be noted that SCells are added during RRC reconfiguration to provide additional radio resources. A CA cell set is a logical grouping of several cells on a base station. Only cells within this group are allowed to be aggregated. The network equipment configures the relevant parameters for the CA cell set.

[0128] Step 502: Insert the SIM card into the relay device and start communication services after logging on to the network.

[0129] In this step, the relay device inserts a SIM card, selects a corresponding cell to be stationed on the network, and performs communication services, for example, the relay device is registered on the 5G network.

[0130] Step 503: The relay device selects an SCell to add and activate.

[0131] In this step, the relay device can send an A4 measurement report to the network device, requesting that the network device configure the corresponding Scell. After receiving the measurement report from the relay device, the network device will send the corresponding Scell ​​to the relay device in an RRC message. The relay device parses the Scell, adds it, and activates it.

[0132] Step 504: The first terminal selects a suitable relay device to establish a connection and perform communication.

[0133] In this step, the first terminal sends query signaling to the relay devices around it, and selects a relay device that meets the threshold conditions (eg, signal threshold, connection threshold, etc.) and has matching capabilities to access and establish service communication.

[0134] Step 505: The first terminal sends a query request for registration frequency band and CA information to the relay device.

[0135] In this step, the first terminal sends a registration frequency band and CA information query signaling to the connected relay device. For example, a pair of signaling can be added specifically for querying and synchronizing the registration frequency band and CA information between the relay device and the first terminal.

[0136] Step 506: The relay device sends the registration frequency band and CA information to the first terminal.

[0137] In this step, after receiving the query signaling of the registered frequency band and CA information sent by the first terminal, the relay device inserts its currently registered frequency band information and CA information into the query response signaling and sends it to the first terminal.

[0138] It should be noted that when the relay device currently has an Scell ​​added, the Scell ​​information will be carried in the CA field in the query response information; when the relay device currently has no Scell ​​added, the query response information will not carry the CA field.

[0139] Step 507: When the first terminal determines that an Scell ​​needs to be added according to the current service status, the first terminal sends an Scell ​​adding request message to the relay device.

[0140] In this step, after the first terminal receives the query response information signaling from the relay device, it parses the frequency band information and CA information carried therein and saves them on the first terminal. When the first terminal performs corresponding communication services, such as gaming or watching live broadcasts, if the first terminal determines that it needs to add a corresponding Scell ​​to increase the network speed and obtain a better network experience, the first terminal will send an Scell ​​addition request message (i.e., a first request message) to the relay device to inform the relay device that the first terminal currently requests to add or configure a Scell. The Scell ​​addition request message includes a measurement report, such as an A4 measurement report.

[0141] Step 508: The relay device synchronizes the Scell ​​add request message sent by the first terminal to the network device.

[0142] In this step, after receiving the measurement report sent by the first terminal, the relay device parses the registration information of the first terminal in the measurement report and performs corresponding processing according to the registration information of the first terminal. The following is an explanation of the following situations:

[0143] (1) When the first SIM card and the second SIM card belong to the same operator, the relay device performs the following processing:

[0144] If the relay device has already added an Scell, it will insert the added CA information into the A4 measurement report and synchronize the measurement report to the network device.

[0145] If the relay device has not currently added an Scell, the relay device sends the measurement report to the network device.

[0146] (2) When the first SIM card and the second SIM card do not belong to the same operator, the relay device directly sends the measurement report to the network device.

[0147] (3) When the first SIM card and the second SIM card do not belong to the same operator, but their two operator networks support inter-network roaming, the relay device performs the following processing:

[0148] If the relay device has already added an Scell, it will insert the added CA information into the A4 measurement report and synchronize the measurement report to the network device.

[0149] If the relay device has not currently added an Scell, the relay device sends the measurement report to the network device.

[0150] The first SIM card is a SIM card used by the relay device to connect to the network, and the second SIM card is a SIM card used by the first terminal to connect to the network.

[0151] Step 509: The network device returns Scell ​​configuration information to the relay device according to the Scell ​​add request message.

[0152] In this step, after receiving the measurement report sent by the relay device, the network device will parse the measurement report to obtain the CA information. If the measurement report contains CA information, the network device directly inserts the Scell ​​information in the CA information into the RRC message and feeds it back to the relay device. If the measurement report does not contain CA information, the network device needs to query and send the Scell ​​information to the relay device based on the current network situation. The Scell ​​information is also inserted into the RRC signaling.

[0153] Step 510: The relay device synchronizes the received Scell ​​configuration information to the first terminal.

[0154] In this step, when the relay device receives the RRC signaling sent by the network device, it will continue to send the RRC signaling to the first terminal.

[0155] Step 511: The first terminal activates the Scell ​​configuration information returned by the relay device.

[0156] In this step, when the first terminal receives the RRC signaling sent by the relay device, it will parse the Scell ​​configuration information in the RRC signaling, update the CA information saved in the first terminal in step 507, and activate the parsed Scell. At this time, the replication of the CA on the relay device to the first terminal is completed.

[0157] Step 512: After the first terminal completes the related services, the Scell ​​returned by the relay device is deactivated.

[0158] In this step, when the first terminal completes the corresponding communication service, the added Scell ​​will be deactivated, which can meet the power saving requirement to a certain extent.

[0159] In summary, the embodiment of the present application combines the advantages of CA and sidelink relay (Rely) technology. After the first terminal selects the relay device, the CA of the relay device can be copied to the first terminal. On the one hand, this can optimize the process of adding CA for the first terminal and improve the efficiency of CA addition. On the other hand, the CA of the first terminal and the relay device can be unified, which can avoid congestion and lag caused by transmission rate mismatch to a certain extent, thereby improving the user's Internet access and other service experience.
