Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information processing method and apparatus. Background Technology

[0002] Current communication systems primarily employ two mechanisms for coverage coverage expansion or blind spot filling: Integrated Access Backhaul (IAB) and Layer 1 Repeater. IAB is relatively expensive, and the L1 Repeater's functionality is too simplistic (only supporting amplification and forwarding). Therefore, existing technologies have proposed introducing a more intelligent repeater, called a Smart Repeater or Network-Controlled Repeater (NCR). In existing technologies, network devices cannot determine whether there are terminals within the NCR coverage area or what functions are available within that area. Therefore, they cannot determine whether data forwarding via the NCR is necessary, thus hindering effective blind spot filling through NCR. Summary of the Invention

[0132] In describing the embodiments of this application, some concepts used in the following description will first be explained.

[0133] I. NCR.

[0134] The structure of NCR is as follows Figure 1 As shown, it includes the following functional entities:

[0135] (1) NCR-MT (Mobile Termination) Entity: This functional entity exchanges control information with network devices (such as NR Node B, gNB) through the control link (C-link). The control information is used to control NCR-Fwd, and the specific control information includes, but is not limited to:

[0136] Beam information;

[0137] Timing information;

[0138] UL / DL TDD configuration information;

[0139] ON / OFF information;

[0140] Power control information.

[0141] (2) NCR-Fwd (Forwarding) entity: This functional entity is used to amplify and forward UL / DL radio frequency signals. The behavior of NCR-Fwd is controlled by the control information received by NCR-MT. For example, NCR-Fwd needs to be turned off when NCR-MT receives OFF indication information.

[0142] Embodiments of this application provide an information processing method and apparatus to solve the problem that network-side devices cannot effectively fill blind spots through NCR.

[0143] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0144] like Figure 2 As shown, an embodiment of this application provides an information processing method applied to NCR, specifically including the following steps:

[0145] Step 201: Determine whether there is a terminal and / or a terminal identifier within the NCR coverage area, and generate indication information;

[0146] The NCR can detect whether there is a terminal within its coverage area, and / or, the NCR determines the identifier of a terminal within its coverage area. Specifically, if a terminal is present within the coverage area of ​​the NCR, the identifier of the terminal within the NCR coverage area can be determined. Optionally, the indication information is determined based on the result of whether a terminal is present within the NCR coverage area and / or the identifier of a terminal within the NCR coverage area. The indication information can indicate whether a terminal is present within the NCR coverage area and / or the identifier of a terminal within the NCR coverage area.

[0147] Step 202: Send the instruction information to the network-side device.

[0148] The NCR is a network control relay. After generating the indication information, the NCR sends the indication information to the network-side device. The network-side device can then know which terminals can be served by the NCR, thereby realizing the control of the terminals through the NCR system.

[0149] In the embodiments of this application, after NCR determines whether there is a terminal within the NCR coverage area and / or the terminal identifier within the NCR coverage area, it generates indication information and sends the indication information to the network-side device so that the network-side device can know which terminals can be provided by NCR, thereby achieving effective blind spot coverage through NCR and improving user experience.

[0150] Optionally, the indication information includes at least one of the following:

[0151] 1) Indication information indicating whether there is a terminal within the NCR coverage area; specifically, it may include: indication information indicating that there is a terminal within the NCR coverage area or indication information indicating that there is no terminal within the NCR coverage area.

[0152] Optionally, the indication information includes indication information on whether there is a terminal within the NCR coverage area, including:

[0153] The indication information carries 1 bit of indication information, the 1 bit of indication information being a first value, indicating that there is a terminal within the coverage area of ​​the NCR; or, the 1 bit of indication information being a second value, indicating that there is no terminal within the coverage area of ​​the NCR.

[0154] In this embodiment, when the NCR reports the indication information to the network-side device, it may carry 1 bit of indication information to indicate whether there is a terminal within the NCR's coverage area. For example, if the first value is "1" and the second value is "0", then: a value of 1 indicates that the NCR has detected a terminal within its coverage area; a value of 0 indicates that the NCR has not detected a terminal within its coverage area.

[0155] Optionally, the indication information may also carry N bits of indication information. Besides indicating whether there is a terminal within the NCR coverage area, the N bits of indication information may also indicate other information. For example, it may indicate a change in the number of terminals within the NCR coverage area. N is an integer greater than 1.

[0156] 2) Terminal identifiers within the NCR coverage area; if there are terminals within the NCR coverage area, the NCR can report the terminal identifiers within the coverage area to the network-side device.

[0157] 3) The NCR receives time-frequency resource information used by the uplink signal sent by the terminal; this may include time-domain resource and / or frequency-domain resource information. The uplink signal can be used to determine whether there is a terminal within the NCR's coverage area. For example, if the NCR receives the uplink signal at the first time-frequency position, it indicates that there is a terminal within the NCR's coverage area.

[0158] As an optional embodiment, determining whether there is a terminal within the NCR coverage area includes:

[0159] If an uplink signal sent by a terminal is received at the first time-frequency location, it is determined that there is a terminal within the NCR coverage area.

[0160] In this embodiment, the NCR receives uplink signals sent by the terminal at a designated first time-frequency location. If an uplink signal is received, it is determined that there is a terminal within the coverage area of ​​the NCR.

[0161] As an optional embodiment, determining the terminal identifier within the NCR coverage area includes:

[0162] The system receives an uplink signal sent by a terminal at a first time-frequency location, the uplink signal carrying a terminal identifier; and determines the terminal identifier carried in the uplink signal as the terminal identifier within the NCR coverage area.

[0163] In this embodiment, the NCR receives an uplink signal sent by the terminal at a designated first time-frequency location. If an uplink signal is received, the terminal identifier carried in the uplink signal is the terminal identifier within the coverage area of ​​the NCR. The terminal identifier is, for example, the terminal's Cell Radio Network Temporary Identifier (C-RNTI).

[0164] Optionally, before receiving the uplink signal sent by the terminal at the first time-frequency position, the method further includes:

[0165] The NCR transmits a downlink signal at the second time-frequency position; wherein the uplink signal is a feedback signal to the downlink signal.

[0166] In this embodiment, the downlink signal can be a downlink detection signal. The NCR transmits the downlink signal at a designated second time-frequency position. If the terminal can detect the downlink signal transmitted by the NCR, the terminal transmits the uplink signal at the first time-frequency position. The terminal receives the downlink signal and can determine the presence of an NCR before transmitting the uplink signal. Optionally, the second time-frequency position can be pre-configured.

[0167] Optionally, the first time-frequency position is determined by one of the following methods:

[0168] Pre-configured;

[0169] Based on the downlink signal, the mapping is determined according to the predetermined mapping rules;

[0170] Indicated by a downlink signal or by indication information contained in a downlink signal.

[0171] In this embodiment, the first time-frequency position can be pre-configured, as agreed upon in the protocol. The first time-frequency position can also be determined according to a predetermined mapping rule based on the downlink signal transmitted by the NCR. For example, if the downlink signal has frequency domain resource R1 at time T1, then the first time-frequency position has frequency domain resource R2 at time T2. The mapping relationship between T1 / R1 and T2 / R2 is pre-set. The downlink signal can also indicate the first time-frequency position, so after the terminal receives the downlink signal, it can determine the time-frequency position for transmitting the uplink signal, and the NCR can also determine the time-frequency position for receiving the uplink signal. Optionally, the downlink signal can be a downlink probe signal.

[0172] As an optional embodiment, sending the indication information to the network-side device includes:

[0173] The indication information is sent to the network-side device via the control link C-link;

[0174] The transmission method of the indication information includes one of the following:

[0175] Carried by Radio Resource Control (RRC) signaling;

[0176] Carried by the Media Access Control (MAC) signaling;

[0177] It is carried by the physical layer uplink message.

[0178] In this embodiment, the NCR reports the indication information to the network-side device via C-link. Specifically, the reporting method can be carried by RRC signaling, MAC signaling, or physical layer uplink messages.

[0179] As an optional embodiment, the triggering condition for sending the indication information to the network-side device includes one of the following:

[0180] Periodic triggering;

[0181] Event triggered.

[0182] In this embodiment, the indication information reported by the NCR to the network-side device can be event-triggered reporting or periodic-triggered reporting. The period for periodic-triggered reporting can be agreed upon by the protocol or configured by the network-side device via C-link.

[0183] Optionally, the triggering event corresponding to the event triggering includes at least one of the following:

[0184] 1) The NCR coverage area changes from having a terminal to having no terminal;

[0185] As an optional embodiment, the NCR can detect whether there is a terminal within the coverage area at predetermined time intervals. If the NCR most recently detected no terminal within the coverage area and previously detected a terminal within the coverage area, the trigger condition for reporting the indication information is met.

[0186] 2) The NCR coverage area changes from having no terminal to having a terminal;

[0187] As an optional embodiment, the NCR can detect whether there is a terminal within the coverage area at predetermined time intervals. If the NCR most recently detected a terminal within the coverage area and previously detected no terminal within the coverage area, the trigger condition for reporting the indication information is met.

[0188] 3) The number of terminals within the NCR coverage area has changed;

[0189] As an optional embodiment, the NCR satisfies the trigger condition for reporting indication information when the number of terminals detected most recently within the coverage area is M, and the number of terminals detected in the previous coverage area was N.

[0190] The following specific examples illustrate the process of determining whether there is a terminal within the NCR coverage area.

[0191] The process of NCR detecting whether there is a terminal within the coverage area and reporting indication information to the network-side device is as follows: Figure 3 As shown, it includes:

[0192] Step 1: The terminal sends an uplink signal;

[0193] Specifically, the terminal sends the uplink signal at a first time-frequency location. This first time-frequency location can be a time-frequency location agreed upon in the protocol.

[0194] Step 2: NCR performs terminal detection;

[0195] In this step, the NCR can detect whether there is a terminal within its coverage area through the access link and generate indication information. Specifically, the NCR receives the uplink signal sent by the terminal at the first time-frequency location. If it receives the uplink signal, it determines that there is a terminal within its coverage area.

[0196] Step 3: NCR notifies network-side devices, such as base stations.

[0197] If the NCR detects a terminal within its coverage area via the access link in step 2, the NCR needs to report the indication information to the base station via C-link.

[0198] The indication information specifically includes one or more of the following:

[0199] Is there an indication of whether there is a terminal within the NCR coverage area?

[0200] Terminal identifiers within the NCR coverage area;

[0201] The NCR detects the time-frequency resources used by the uplink signal sent by the terminal.

[0202] Specifically, the reporting method for the indication information can be one of the following:

[0203] Carry using RRC signaling;

[0204] Carry using MAC signaling;

[0205] Carry it using physical layer uplink messages.

[0206] For example, if the NCR only reports whether there is a terminal within its coverage area, then the NCR reports the detection result (i.e., an indication of whether there is a terminal within its coverage area) to the network-side device via C-link. When reporting the detection result, the RRC signaling, MAC signaling, or physical layer uplink message may carry only 1 bit of indication information. The value of this 1 bit is 1, indicating that the NCR has detected a terminal within its coverage area; the value of this 1 bit is 0, indicating that the NCR has not detected a terminal within its coverage area. Alternatively, the value of this 1 bit is 0, indicating that the NCR has detected a terminal within its coverage area; the value of this 1 bit is 1, indicating that the NCR has not detected a terminal within its coverage area.

[0207] The NCR can report indication information in the form of event-triggered reporting or periodic reporting. The period for periodic reporting can be agreed upon by the protocol or configured by the base station through C-link.

[0208] The triggering event for event reporting can be one or more of the following, or a combination thereof:

[0209] 1) The NCR coverage area changes from having a terminal to having no terminal;

[0210] 2) The NCR coverage area changes from having no terminal to having a terminal;

[0211] 3) The number of terminals within the NCR coverage area has changed.

[0212] When the network-side device receives the indication information reported by the terminal, it can perform the following operations: switch the relay NCR-Fwd function entity on or off, and determine whether to provide services to the terminal through NCR.

[0213] As an optional embodiment, the process of the NCR detecting whether there is a terminal within the coverage area and reporting indication information to the network-side device is as follows: Figure 4 As shown, it includes:

[0214] Step 0: NCR sends a downlink signal; optionally, the downlink signal may be a downlink probe signal.

[0215] In this step, the NCR sends a downlink signal at the second time-frequency position, where the second time-frequency position can be a time-frequency position agreed upon in the protocol.

[0216] Step 1: The terminal sends an uplink signal.

[0217] Specifically, if the terminal detects a downlink signal sent by the NCR, the terminal also sends an uplink signal at the first time-frequency position.

[0218] The first time-frequency position can be a time-frequency position agreed upon in the protocol; or, the first time-frequency position is the time-frequency position indicated in the downlink signal sent by the NCR; or, the first time-frequency position is the time-frequency position determined according to a certain mapping rule based on the downlink signal sent by the NCR.

[0219] Step 2: NCR performs terminal detection.

[0220] In this step, the NCR can detect whether there is a terminal within its coverage area via the access link and generate indication information. Specifically, the NCR receives the uplink signal sent by the terminal at the first time-frequency location. If it receives the uplink signal, it determines that there is a terminal within its coverage area.

[0221] Step 3: NCR notifies network-side devices, such as base stations.

[0222] If the NCR detects a terminal within its coverage area via the access link in step 2, the NCR can report the corresponding indication information to the network-side device via C-link.

[0223] The indication information specifically includes one or more of the following:

[0224] Is there an indication of whether there is a terminal within the NCR coverage area?

[0225] Terminal identifiers within the NCR coverage area;

[0226] The NCR detects the time-frequency resources used by the uplink signal sent by the terminal.

[0227] Specifically, the reporting method for the indication information can be one of the following:

[0228] Carry using RRC signaling;

[0229] Carry using MAC signaling;

[0230] Carry it using physical layer uplink messages.

[0231] For example, if the NCR only reports whether there is a terminal within its coverage area, then the NCR reports the detection result (i.e., an indication of whether there is a terminal within its coverage area) to the network-side device via C-link. When reporting the detection result, the RRC signaling, MAC signaling, or physical layer uplink message may carry only 1 bit of indication information. The value of this 1 bit is 1, indicating that the NCR has detected a terminal within its coverage area; the value of this 1 bit is 0, indicating that the NCR has not detected a terminal within its coverage area. Alternatively, the value of this 1 bit is 0, indicating that the NCR has detected a terminal within its coverage area; the value of this 1 bit is 1, indicating that the NCR has not detected a terminal within its coverage area.

[0232] The NCR can report indication information in the form of event-triggered reporting or periodic reporting. The period for periodic reporting can be agreed upon by the protocol or configured by the base station through C-link.

[0233] The triggering event for event reporting can be one or more of the following, or a combination thereof:

[0234] 1) The NCR coverage area changes from having a terminal to having no terminal;

[0235] 2) The NCR coverage area changes from having no terminal to having a terminal.

[0236] When the network-side device receives the indication information reported by the terminal, it can perform the following operations: switch the relay NCR-Fwd function entity on or off, and determine whether to provide services to the terminal through NCR.

[0237] As an optional embodiment, the process by which the NCR determines whether a terminal is within the coverage area and identifies the terminal within the coverage area is as follows: Figure 5 As shown, it includes:

[0238] Step 1: The terminal sends an uplink signal;

[0239] Specifically, the terminal sends an uplink signal at a first time-frequency location. This first time-frequency location can be a time-frequency location agreed upon in the protocol.

[0240] Step 2: NCR performs terminal detection;

[0241] In this step, the NCR detects whether there is a terminal within its coverage area. If there is a terminal within its coverage area, it obtains the terminal identifier within its coverage area and generates indication information. Specifically: the NCR receives the uplink signal sent by the terminal at the first time-frequency location. If the NCR receives the uplink signal, it determines the terminal identifier information based on the information carried by the uplink signal.

[0242] Step 3: NCR notifies network-side devices, such as base stations.

[0243] If, in step 2, the NCR detects a terminal within its coverage area and obtains the terminal identifier via the access link, the NCR needs to report the indication information to the network-side device via C-link.

[0244] Specifically, the reporting method for the indication information can be one of the following:

[0245] Carry using RRC signaling;

[0246] Carry using MAC signaling;

[0247] Carry it using physical layer uplink messages.

[0248] If the NCR determines that there is a terminal within its coverage area and obtains the terminal identifier within its coverage area, then the NCR in this step can report the indication information to the network-side device through C-link. Specifically, it can be carried in the RRC signaling, MAC signaling, or physical layer uplink message, which includes terminal identification information, including but not limited to the terminal's C-RNTI.

[0249] The reporting method for the indication information can be event-triggered reporting or periodic reporting. The period for periodic reporting can be agreed upon by the protocol or configured by the base station via C-link for NCR reporting.

[0250] When an event is reported, the specific triggering event can be one or more of the following, or a combination thereof:

[0251] The NCR coverage area changed from having a terminal to having no terminal;

[0252] The NCR coverage area changed from having no terminals to having terminals;

[0253] The number of terminals within the NCR coverage area has changed.

[0254] When the network-side device receives the indication information reported by the NCR, it can perform the following operations: switch the relay NCR-Fwd function entity on or off, and determine whether to provide services to the terminal through NCR.

[0255] As an optional embodiment, the process by which the NCR determines whether a terminal is within the coverage area and identifies the terminal within the coverage area is as follows: Figure 6 As shown, it includes:

[0256] Step 0: NCR sends a downlink signal, which may optionally be a downlink detection signal.

[0257] In this step, the NCR sends a downlink signal at the second time-frequency position, where the second time-frequency position can be a time-frequency position agreed upon in the protocol.

[0258] Step 1: The terminal sends an uplink signal.

[0259] Specifically, if the terminal detects a downlink signal sent by the NCR, the terminal sends an uplink signal at the first time-frequency position.

[0260] The first time-frequency position can be a time-frequency position agreed upon in the protocol; or, the first time-frequency position is the time-frequency position indicated in the downlink signal sent by the NCR; or, the first time-frequency position is the time-frequency position determined according to a certain mapping rule based on the downlink signal sent by the NCR.

[0261] Step 2: NCR performs terminal detection.

[0262] In this step, the NCR can detect whether there is a terminal within its coverage area via the access link. If a terminal is found, its terminal identifier is obtained, and indication information is generated. Specifically, the NCR receives the uplink signal sent by the terminal at the first time-frequency location. If the uplink signal is received, it determines that there is a terminal within its coverage area.

[0263] Step 3: NCR notifies network-side devices, such as base stations.

[0264] If the NCR detects a terminal within its coverage area via the access link in step 2, the NCR can report the corresponding indication information to the network-side device via C-link.

[0265] The indication information specifically includes one or more of the following:

[0266] Is there an indication of whether there is a terminal within the NCR coverage area?

[0267] Terminal identifiers within the NCR coverage area;

[0268] The NCR detects the time-frequency resources used by the uplink signal sent by the terminal.

[0269] Specifically, the reporting method for the indication information can be one of the following:

[0270] Carry using RRC signaling;

[0271] Carry using MAC signaling;

[0272] Carry it using physical layer uplink messages.

[0273] If the NCR determines that there is a terminal within its coverage area and obtains the terminal identifier within its coverage area, then the NCR in this step can report the indication information to the network-side device through C-link. Specifically, it can be carried in the RRC signaling, MAC signaling, or physical layer uplink message, which includes terminal identification information, including but not limited to the terminal's C-RNTI.

[0274] The NCR can report indication information in the form of event-triggered reporting or periodic reporting. The period for periodic reporting can be agreed upon by the protocol or configured by the base station through C-link.

[0275] The triggering event for event reporting can be one or more of the following, or a combination thereof:

[0276] 1) The NCR coverage area changes from having a terminal to having no terminal;

[0277] 2) The NCR coverage area changes from having no terminal to having a terminal;

[0278] 3) The number of terminals within the NCR coverage area changes.

[0279] When the network-side device receives the indication information reported by the terminal, it can perform the following operations: switch the relay NCR-Fwd function entity on or off, and determine whether to provide services to the terminal through NCR.

[0280] In the embodiments of this application, after NCR determines whether there is a terminal within the NCR coverage area and / or the terminal identifier within the NCR coverage area, it generates indication information and sends the indication information to the network-side device so that the network-side device can know which terminals can be provided by NCR, thereby achieving effective blind spot coverage through NCR and improving user experience.

[0281] like Figure 7 As shown in the embodiments of this application, an information processing method is also provided, applied to a network-side device, including:

[0282] Step 701: The network-side device determines whether there is a terminal and / or a terminal identifier within the NCR coverage area.

[0283] In this embodiment, the network-side device can determine whether there is a terminal within the coverage area of ​​the NCR. When there is a terminal within the coverage area of ​​the NCR, it can also determine the terminal identifier within the coverage area, thereby selecting a suitable NCR node to provide services to the terminal, improving network performance, and solving coverage blind spots.

[0284] As an optional embodiment, determining whether there is a terminal and / or a terminal identifier within the NCR coverage area includes:

[0285] Method 1: Receive the indication information sent by NCR, and determine whether there is a terminal and / or the terminal identifier within the NCR coverage area based on the indication information;

[0286] or,

[0287] Method 2: Receive measurement reports sent by the terminal, and determine whether there is a terminal and / or a terminal identifier within the NCR coverage area based on the measurement reports.

[0288] In this embodiment, for method one, the NCR detects whether there is a terminal within the NCR coverage area and / or the terminal identifier within the NCR coverage area, and generates indication information; the NCR sends the indication information to the network-side device. The indication information is determined based on the result of whether there is a terminal within the NCR coverage area and / or the terminal identifier within the NCR coverage area.

[0289] In the second method, the network-side device determines whether there is a terminal and / or a terminal identifier within the NCR coverage area based on the measurement report sent by the terminal. Specifically, the terminal can measure the downlink signal sent by the NCR and send a measurement report to the network-side device. Optionally, the downlink signal can be a downlink probe signal.

[0290] Optionally, the indication information includes at least one of the following:

[0291] 1) Indication information indicating whether there is a terminal within the NCR coverage area; specifically, it may include: indication information indicating that there is a terminal within the NCR coverage area or indication information indicating that there is no terminal within the NCR coverage area.

[0292] Optionally, determining whether there is a terminal within the NCR coverage area based on the indication information includes:

[0293] Based on the 1-bit indication information carried by the indication information, determine whether there is a terminal within the NCR coverage area;

[0294] Wherein, the 1-bit indication information is set to a first value, indicating that there is a terminal within the NCR coverage area; or, the 1-bit information indication is set to a second value, indicating that there is no terminal within the NCR coverage area.

[0295] In this embodiment, when the NCR reports the indication information to the network-side device, it may carry 1 bit of indication information to indicate whether there is a terminal within the NCR's coverage area. For example, if the first value is "1" and the second value is "0", then: a value of 1 indicates that the NCR has detected a terminal within its coverage area; a value of 0 indicates that the NCR has not detected a terminal within its coverage area.

[0296] Optionally, the indication information may also carry N bits of indication information. Besides indicating whether there is a terminal within the NCR coverage area, the N bits of indication information may also indicate other information. For example, it may indicate a change in the number of terminals within the NCR coverage area. N is an integer greater than 1.

[0297] 2) Terminal identifiers within the NCR coverage area; if there are terminals within the NCR coverage area, the NCR can report the terminal identifiers within the coverage area to the network-side device.

[0298] 3) The NCR receives time-frequency resource information used by the uplink signal sent by the terminal; this may include time-domain resource and / or frequency-domain resource information. The uplink signal can be used to determine whether there is a terminal within the NCR's coverage area. For example, if the NCR receives the uplink signal at the first time-frequency position, it indicates that there is a terminal within the NCR's coverage area.

[0299] As an optional embodiment, before receiving the measurement report sent by the receiving terminal, the method further includes:

[0300] Configuration information for sending downlink signals to the NCR, the configuration information including information on the second time-frequency position at which the NCR sends the downlink signals;

[0301] and / or

[0302] The measurement configuration information is sent to the terminal, including time-frequency location indication information for the terminal's downlink signal measurement and / or measurement reporting configuration information.

[0303] In this embodiment, the downlink signal can be a downlink probe signal. The network-side device can send configuration information of the downlink signal to the NCR, such as the second time-domain location where the NCR sends the downlink signal. The NCR can then send the downlink signal at the second time-frequency location; if the terminal can detect the downlink signal, the terminal can send an uplink signal at the first time-frequency location; if the NCR receives the uplink signal at the first time-frequency location, it determines that there is a terminal within the coverage area of ​​the NCR; or, the terminal measures the downlink signal and reports the measurement to the network-side device, and the network-side device determines whether there is a terminal within the coverage area of ​​the NCR based on the measurement report.

[0304] The network-side device can also send measurement configuration information to the terminal. This measurement configuration information includes time-frequency location indication information for the terminal's measurement of downlink signals and / or measurement reporting configuration information. The time-frequency location indication information indicates a second time-frequency location where the terminal receives the downlink signal. The measurement reporting configuration information may include information that the terminal needs to measure and report. The terminal measures the downlink signal transmitted by the NCR according to the measurement configuration information and reports the measurement to the network-side device. The network-side device determines whether there is a terminal within the NCR coverage area based on the measurement results reported by the terminal.

[0305] In embodiments of this application, the network-side device determines whether there are terminals and / or terminal identifiers within the NCR coverage area, thereby identifying which terminals can be served by the NCR and selecting appropriate NCR nodes to provide services to the terminals, improving network performance and resolving coverage blind spots.
