Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal sending, measurement reporting method, device, terminal and network equipment. Background Art

[0002] In the existing FR1+FR2 Carrier Aggregation (CA) scenario, in order to save terminal energy, the FR2 secondary cell (SCell) may not always be in an activated state. If the FR2 SCell is in an inactive state, it takes a long time delay to change from the inactive state to the active state.

[0003] Generally speaking, 4 cycles are required for FR2 Scell ​​activation, including Automatic Gain Control (AGC) 1, AGC2, Coarse Sync and Layer 1 measurement (L1 measurement) processes. Assuming that the terminal has 8 receiving beams, for each cycle, the terminal needs to use a receiving beam to receive 32 transmitting beams within 20ms to determine the best transmitting beam and receiving beam. Therefore, the FR2 Scell ​​activation delay is: 20ms (synchronization signal block (SSB) cycle) * 8 (number of terminal receiving beams) * 4 cycles (AGC1, AGC2, Coarse Sync, L1 measurement) = 640ms.

[0004] It can be seen that the current FR2 Scell ​​has a long activation time and poor user experience. Summary of the invention

[0160] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0161] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein, for example, are implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0162] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0163] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0164] The relevant concepts mentioned in this application are briefly described below.

[0165] The beam scanning process of FR2 scell is:

[0166] Step 1: The base station configures the terminal to feedback the beam measurement results and the resources used for beam measurement through high-level signaling (Channel State Information Report Configuration (CSI-ReportConfig)).

[0167] Step 2: If the reference signal resource used for beam measurement is a periodic channel state information reference signal (CSI-RS), after receiving the radio resource control (RRC) configuration of the base station, the terminal receives the configured CSI-RS on the indicated time / frequency resource and measures the layer 1 reference signal receiving power (L1-RSRP). If the reference signal resource used for beam measurement is a semi-persistent CSI-RS, after receiving the RRC configuration of the base station and the media access control control element (MAC CE) trigger signaling, the terminal receives the configured CSI-RS on the time / frequency resource configured by the base station and measures the L1-RSRP until receiving the deactivated MAC-CE signaling. If the reference signal resource used for beam measurement is a non-periodic CSI-RS, after receiving the L1 DCI 0_1 / 0_2 trigger signaling, the terminal receives and measures the configured CSI-RS according to the time and frequency resources indicated in the base station DCI signaling.

[0168] Step 3: The terminal provides feedback on the beam measurement content. The uplink resources used for the feedback are configured through high-level signaling (periodic or semi-continuous measurement resources) or DCI indication (non-periodic measurement resources).

[0169] Step 4: The beam measurement feedback adopts differential feedback, including a 7-bit absolute value L1-RSRP and N 4-bit differential L1-RSRPs. The differential L1-RSRP is obtained by differentiating the other L1-RSRPs except the first L1-RSRP from the first absolute value L1-RSRP (7 bits).

[0170] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The signal transmission, measurement reporting method, device, terminal and network equipment provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0171] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 2 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (UE), for example, it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems or a gateway station supporting satellite communication, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0172] The embodiments of the present application provide a signal transmission and measurement reporting method, apparatus, terminal, and network device to reduce the delay of Scell ​​activation.

[0173] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0175] Step S201, triggering a target reference signal set corresponding to a target secondary cell through a primary cell;

[0176] It should be noted here that in the carrier aggregation scenario, the network device will configure a primary cell and one or more secondary cells for the terminal. The primary cell is always in an activated state, while the secondary cell may not always be in an activated state, but is activated when in use; the primary cell and the secondary cell are both located under the same network device (for example, a base station), and the secondary cell activation is triggered by the primary cell under the network device. When secondary cell activation is required, the specific secondary cell will send relevant reference signals to allow the terminal to perform beam measurement reporting.

[0177] It should be noted that the target reference signal set is at least a part of the reference signal set in the reference signal set pre-configured for the target secondary cell. When the network device configures the reference signal set corresponding to the target secondary cell for the terminal, each reference signal set includes not only an indication of the reference signal (for example, a reference signal index or number), but also includes a reference signal sending-related indication, for example, a sending time offset, a sending period, a sending mode of the set (for example, whether the set needs to be repeatedly transmitted, the number of repeated transmissions, etc.), etc. The network device triggers the target reference signal set to the terminal (triggering the target reference signal set can be understood as the network device notifying the target reference signal set to the terminal). After obtaining which sets are triggered by the network equipment, the terminal can know which reference signals need to be received and at which positions the corresponding reference signals need to be received; that is, the purpose of triggering the target reference signal set can be understood as to notify the terminal which reference signals to receive and the receiving positions of the reference signals; optionally, triggering the target reference signal set corresponding to the target secondary cell through the primary cell can be understood as: sending a reference signal set trigger indication to the terminal through the primary cell, and the reference signal set trigger indication is used to indicate to the terminal the target reference signal set based on which the target secondary cell sends the reference signal.

[0178] Optionally, the target reference signal set includes one of the following:

[0179] A11, a plurality of reference signal sets;

[0180] This situation can be understood as the primary cell needs to trigger multiple reference signal sets corresponding to the target secondary cell, that is, the target secondary cell needs to send reference signals in multiple reference signal sets to the terminal.

[0181] A12. A reference signal set is sent repeatedly N times, where N is an integer greater than or equal to 2;

[0182] This situation can be understood as the primary cell needs to trigger a reference signal set corresponding to the target secondary cell, and the reference signal in the reference signal set needs to be sent repeatedly N times, that is, the target secondary cell needs to send the reference signal in a reference signal set to the terminal multiple times.

[0183] A13, a reference signal set;

[0184] This situation can be understood as the primary cell only triggering one reference signal set corresponding to the target secondary cell, that is, the target secondary cell only needs to send a reference signal in one reference signal set to the terminal.

[0185] It should also be noted that the reference signal set mentioned in the embodiment of the present application includes at least one reference signal (RS). Optionally, the reference signal set can also be called a reference signal resource set (RS resource set), and the reference signal can also be called a reference signal resource (RS resource).

[0186] Step S202: sending a reference signal corresponding to the target secondary cell to the terminal through the target secondary cell according to the target reference signal set;

[0187] The reference signal is used by the terminal to perform beam measurement reporting of the target secondary cell, the reference signal is associated with the SSB used for beam measurement of the primary cell, and the transmission period of the reference signal is less than the transmission period of the SSB;

[0188] It should be noted that for the network device, it is the sender of the reference signal, therefore, the sending period of the reference signal refers to the period for the network device to send the reference signal; the sending period of the SSB is the period for sending the SSB. For the terminal, it is the receiver of the reference signal, that is, on the terminal side, it can also be called the receiving period of the reference signal, that is, the period for the terminal to receive the reference signal, and the sending period of the SSB can also be called the receiving period of the SSB, that is, the period for the terminal to receive the SSB. The sending period and receiving period here are both used to indicate the reference signal or SSB, so the two have the same meaning.

[0189] It should be noted here that after receiving the reference signal sent by the network device through the secondary cell, the terminal needs to perform beam measurement based on the reference signal, obtain the beam measurement reporting result, and report it to the network device. For example, the beam measurement reporting result can be L1-RSRP or layer 1 signal to interference and noise ratio (L1-SINR).

[0190] It should be noted that compared with the current secondary cell activation, the embodiment of the present application does not measure the SSB when activating the secondary cell, but a reference signal with a sending period less than the SSB, and the reference signal is associated with the SSB, for example, the reference signal and the SSB are quasi-co-sited (QCL), so that the delay occupied by the beam measurement during the secondary cell activation process can be reduced, and then the delay of the beam scanning can be reduced, thereby reducing the delay of the secondary cell activation.

[0191] Optionally, the reference signal in the embodiment of the present application may be, for example, a channel state information reference signal (CSI-RS), which may be referred to as a temporary beam measurement CSI-RS (Temporary CSI-RS for BM) in the present application.

[0192] Optionally, in the embodiment of the present application, the frequency point of the primary cell is FR1, so the primary cell can also be called the FR1 primary cell, and the frequency point of the secondary cell is FR2, so the secondary cell can also be called the FR2 secondary cell. The following is an explanation of the method of activating the secondary cell by applying the embodiment of the present application as follows:

[0193] In the embodiment of the present application, the beam scanning of the secondary cell is optimized through the measurement results of the primary cell, and the activation time of the secondary cell carrier is reduced. The beam scanning of the primary cell obtains the beam direction information at the SSB level, and according to the direction of the optimal SSB, the direction correlation between the primary cell and the secondary cell is used to configure the Temporary CSI-RS for BM around it for beam scanning to obtain the beam information of the secondary cell.

[0194] For example, the base station configures the SSB resource set {SSB1, SSB2} through RRC, and the base station configures the Temporary CSI-RSfor BM set at the same time. Specifically, each Temporary CSI-RS for BM in the Temporary CSI-RS for BM set is associated with the same SSB in the SSB resource set. The association here refers to the QCL-type D reference SSB of the Temporary CSI-RS for BM, such as the 8 CSI-RS included in the Temporary CSI-RS for BM set, namely {CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, CSI-RS6, CSI-RS7, CSI-RS8}, where the QCL-type D of each CSI-RS in the Temporary CSI-RS for BM set refers to SSB1. During the beam scanning process, the terminal first determines that the optimal SSB direction is SSB1 through the measurement results of the primary cell, and then activates the 8 CSI-RS in the Temporary CSI-RSfor BM set associated with SSB1 for beam scanning.

[0195] For example, Figure 3As shown, the secondary cell activation delay obtained by adopting the method of the embodiment of the present application is: 2ms (Temporary CSI-RS for BM period) * 8 (number of terminal receiving beams) * 4 periods (AGC1, AGC2, CoarseSync, L1 measurement) = 64ms, which is significantly shorter than the delay for secondary cell activation using SSB.

[0196] It should be noted that the reference signal mentioned in the embodiments of the present application is UE-specific, that is, different terminals use different reference signals. The reference signal can be periodic, semi-persistent, or aperiodic.

[0197] Optionally, in one implementation, the triggering of the target reference signal set corresponding to the target secondary cell by the primary cell specifically includes:

[0198] When or after the activation signaling of the target secondary cell is sent, the target reference signal set corresponding to the target secondary cell is triggered through the primary cell.

[0199] That is to say, the primary cell may trigger the target reference signal set at the same time when sending the activation signaling of the target secondary cell (for example, the activation signaling is the media access control control unit (MAC CE) for activating the secondary cell), that is, the operations of activating the target secondary cell and triggering the target reference signal set corresponding to the target secondary cell are both implemented through the activation signaling of the target secondary cell; the primary cell may also trigger the target reference signal set after sending the activation signaling of the target secondary cell, that is, first send the activation signaling of the target secondary cell, and then send specific signaling or specific information to trigger the target reference signal set corresponding to the target secondary cell. Optionally, the specific signaling may be a secondary cell beam measurement reference signal trigger signaling, for example, it may be a MAC CE for triggering a reference signal set; or, the specific information may also be secondary cell beam measurement reference signal control information, for example, it may be downlink control information (DCI) for triggering a reference signal set.

[0200] It should be noted that by triggering the target reference signal set when the activation signaling of the target secondary cell is sent, the number of signaling transmissions can be reduced and resource overhead can be reduced; by triggering the target reference signal set after the activation signaling of the target secondary cell is sent, precise control of the triggering of the target reference signal set can be achieved.

[0201] Optionally, in one implementation manner, the specific implementation of triggering the target reference signal set corresponding to the target secondary cell by the primary cell when the activation signaling of the target secondary cell is sent or after the activation signaling of the target secondary cell is sent includes the following:

[0202] B11. When the reference signal is a periodic reference signal, when the activation signaling of the target secondary cell is sent once through the primary cell, the target reference signal set corresponding to the target secondary cell is triggered through the activation signaling of the target secondary cell;

[0203] It should be noted that when the network equipment adopts periodic reference signals, the target reference signal set corresponding to the target secondary cell can be triggered simultaneously when the target secondary cell is activated. That is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signal in the target reference signal set according to the pre-configured period and sending time offset, and the terminal also receives the reference signal according to the same period and sending time offset after receiving the activation signaling of the target secondary cell.

[0204] It should be noted that the triggering of the periodic reference signal is relatively simple and can be directly triggered by the activation signaling of the target secondary cell, which can reduce the number of signaling transmissions and reduce resource overhead.

[0205] B12. When the reference signal is a semi-persistent reference signal, when the activation signaling of the target secondary cell is sent once through the primary cell, the target reference signal set corresponding to the target secondary cell is triggered through the activation signaling of the target secondary cell; or after sending the activation signaling of the target secondary cell, the primary cell sends a secondary cell beam measurement reference signal trigger signaling once, and the target reference signal set corresponding to the target secondary cell is triggered through the secondary cell beam measurement reference signal trigger signaling;

[0206] It should be noted that, in the case where the network device adopts a semi-persistent reference signal, optionally, in one case, when the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered at the same time, that is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signals in the target reference signal set according to the sending period and sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signals according to the same period and sending time offset after receiving the activation signaling of the target secondary cell. Optionally, in another case, after the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal trigger signaling can be sent again, and then the target secondary cell sends the reference signals in the target reference signal set according to the sending period and sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signals according to the same period and sending time offset after receiving the secondary cell beam measurement reference signal trigger signaling.

[0207] It should be noted that for the semi-persistent reference signal, not only does it need to start sending, but it also needs to stop sending. Optionally, in one implementation, the specific implementation of sending the reference signal corresponding to the target secondary cell to the terminal through the target secondary cell according to the target reference signal set includes:

[0208] In a process of sending a reference signal corresponding to the target secondary cell to the terminal through the target secondary cell according to the target reference signal set, if a termination condition is met, terminating sending the reference signal corresponding to the target secondary cell through the target secondary cell;

[0209] The termination condition includes one of the following:

[0210] B121. Time agreed upon in the agreement;

[0211] That is to say, it is possible to agree through a protocol on when to terminate the sending of the reference signal. For example, the protocol stipulates that the sending of the reference signal shall be terminated M time slots after the MAC CE for activating the secondary cell takes effect. Then, after sending the MAC CE for activating the secondary cell, the secondary cell starts to send the reference signal at an adapted position. When it reaches M slots after the MAC CE for activating the secondary cell takes effect, the secondary cell terminates sending the reference signal.

[0212] B122. The count value of the set transmission times counter reaches a preset value, wherein the transmission times counter is incremented each time the reference signal is sent;

[0213] This situation can be understood as: the secondary cell sets a transmission count counter, and after the counter is turned on, the count value is increased by one each time the reference signal is sent, until the count value reaches a preset value, and the secondary cell stops sending the reference signal.

[0214] B123, reference signal sending timer times out;

[0215] This situation can be understood as: the secondary cell sets a reference signal sending timer, starts the timer and then starts timing. When the timer reaches the timing duration, it times out, and the secondary cell stops sending the reference signal.

[0216] B124, receiving the beam reporting result sent by the terminal;

[0217] Optionally, the beam reporting result can also be understood as a beam report.

[0218] It should be noted that this situation can be understood as event termination, that is, the beam reporting result sent by the terminal is regarded as an event. When the secondary cell obtains the event, it is considered that the termination of the reference signal sending is triggered. The secondary cell can stop sending the reference signal immediately, or stop sending the reference signal after a preset time after the event occurs; optionally, the present application only gives an example of the event of receiving the beam reporting result sent by the terminal, and all events that can terminate the reference signal sending belong to the protection scope of this application.

[0219] It should also be noted here that when the secondary cell terminates the sending of the reference signal, in order to reduce the overhead of the terminal detecting the reference signal, the network device needs to send a signal termination signaling to the terminal through the secondary cell to indicate to the terminal that the reference signal has stopped sending. After receiving the signaling, the terminal stops receiving the reference signal. Optionally, the signal termination signaling can be a target secondary cell deactivation signaling (also referred to as a signaling for deactivating the target secondary cell) or a reference signal deactivation signaling (also referred to as a signaling for deactivating the reference signal).

[0220] For example, the secondary cell sends reference signal 1, reference signal 2 and reference signal 3 according to a preset period. After the secondary cell sends reference signal 1 in a certain period, if any one of the above B121-B124 is met, the secondary cell terminates the sending of reference signal 2 and reference signal 3 in the current period and the reference signals in all subsequent periods, and sends a signaling to deactivate the reference signal to the terminal. After receiving the signaling, the terminal no longer receives reference signal 2 and reference signal 3 in the current period and the reference signals in all subsequent periods.

[0221] It should be noted that for the semi-persistent reference signal, not only triggering is required, but also control of terminating transmission is required, so that the network equipment can flexibly use the reference signal.

[0222] B13. When the reference signal is a non-periodic reference signal, the primary cell sends a secondary cell beam measurement reference signal trigger signaling or a secondary cell beam measurement reference signal control information once after sending the activation signaling of the target secondary cell, and the target reference signal set corresponding to the target secondary cell is triggered by the secondary cell beam measurement reference signal trigger signaling or the secondary cell beam measurement reference signal control information; or when the activation signaling of the target secondary cell is sent once by the primary cell, the target reference signal set corresponding to the target secondary cell is triggered by the activation signaling of the target secondary cell.

[0223] It should be noted that, in the case where the network device adopts a non-periodic reference signal, optionally, in one case, when the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered at the same time, that is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the activation signaling of the target secondary cell. Optionally, in another case, after the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal trigger signaling can be sent again, and then the target secondary cell sends the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the secondary cell beam measurement reference signal trigger signaling. Optionally, in another case, after activating the target secondary cell, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal control information can be sent again, and then the target secondary cell sends the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the secondary cell beam measurement reference signal control information.

[0224] It should be noted that, for the non-periodic reference signal, it only needs to be triggered to be sent, and after the reference signal is sent, it will no longer be sent continuously, so that network energy saving can be taken into account during the process of activating the secondary cell.

[0225] Optionally, in one implementation, the secondary cell beam measurement reference signal trigger signaling, the activation signaling of the target secondary cell, or the secondary cell beam measurement reference signal control information includes one of the following:

[0226] C11, a bit map, each bit in the bit map corresponds to a reference signal set, and each bit in the bit map is used to indicate whether the corresponding reference signal set is triggered or not;

[0227] It should be noted that in this case, each reference signal set configured for the target secondary cell corresponds to a bit, and the reference signal set to be triggered is set to the value of the corresponding bit to indicate the trigger. For example, 1 is used to indicate triggering the reference signal set, and 0 is used to indicate not triggering the reference signal set; or, 0 is used to indicate triggering the reference signal set, and 1 is used to indicate not triggering the reference signal set.

[0228] C12, reference signal triggering state indication information, where the reference signal triggering state indication information is used to indicate one or more reference signal sets that are triggered;

[0229] It should be noted that in this case, a reference signal triggering status indication information is directly carried, and the indication information is used to indicate a triggered reference signal set. For example, the indication information is used to indicate the identification information (for example, a set number or index) of a triggered reference signal set.

[0230] Optionally, in one implementation, the method further includes:

[0231] Sending configuration information of a reference signal to the terminal through the primary cell;

[0232] Further, the triggering of a target reference signal set corresponding to a target secondary cell by the primary cell includes:

[0233] Based on the configuration information, a target reference signal set corresponding to a target secondary cell is triggered by the primary cell, and the target reference signal set is included in the configuration information.

[0234] It should be noted that before using the reference signal set, it is necessary to configure the reference signal set first. When the main cell triggers the target reference signal set, it also selects from the pre-configured reference signal set to ensure that the terminal can accurately know which reference signal sets are triggered by the main cell, and ensure that the terminal can accurately receive the reference signal.

[0235] Optionally, in one implementation, the configuration information includes at least one of the following:

[0236] D11, a reference signal set corresponding to the target secondary cell, the reference signal set including at least one reference signal and a transmission time offset corresponding to each reference signal;

[0237] For example, a reference signal set including 64 reference signals is configured for the target secondary cell, and a corresponding transmission time offset is configured for each reference signal.

[0238] For example, taking the reference signal as CSI-RS, the configuration IE that can be used for the reference signal set is:

[0239]

[0240]

[0241] Wherein, aperiodicTriggeringOffset represents the offset of the periodic triggering of the set. Further, the configuration IE that can be used for the reference signal is:

[0242]

[0243] Wherein, periodicityAndOffset represents the transmission time offset and period of the reference signal. Further, the configuration IE that can be used for periodicityAndOffset of the reference signal is:

[0244]

[0245]

[0246] D12, multiple reference signal sets corresponding to the target secondary cell, each reference signal set including the number of repetitions of the reference signal set, at least one reference signal, and a transmission time offset corresponding to the reference signal set;

[0247] It should be noted that in this case, at least two reference signal sets are configured, and a number of repetition transmissions and a transmission time offset are configured for each reference signal set, indicating that the set needs to be repeatedly transmitted when being transmitted.

[0248] For example, taking the reference signal as CSI-RS, the configuration IE that can be used for the reference signal set is:

[0249]

[0250]

[0251] Here, Slot_repetition indicates the number of times the reference signal set is repeatedly sent.

[0252] D13, multiple reference signal sets corresponding to the target secondary cell, each of the reference signal sets including at least one reference signal and a transmission time offset corresponding to the reference signal set;

[0253] It should be noted that in this case, at least two reference signal sets are configured, each reference signal set is set with a corresponding transmission time offset, and the number of repeated transmissions of the set is not set in this case, indicating that the reference signal set does not need to be repeatedly transmitted during actual transmission.

[0254] The above configuration and trigger combination are illustrated as follows.

[0255] Example 1: When D11 is configured only for the target secondary cell, that is, only the configured reference signal set (corresponding to A13 above) can be triggered during set triggering. This situation can be used for sending periodic reference signals, semi-persistent reference signals, and aperiodic reference signals.

[0256] Example 2: When D12 is configured only for the target secondary cell, that is, when the set trigger is performed, any one of the configured reference signal sets (corresponding to the above-mentioned A12) or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-persistent reference signals, and non-periodic reference signals.

[0257] Example 3: When D13 is configured only for the target secondary cell, that is, when the set trigger is performed, any one of the configured reference signal sets (corresponding to the above-mentioned A13) or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-persistent reference signals, and non-periodic reference signals.

[0258] Example 4: When D11 and D12 are configured for the target secondary cell, that is, when the set trigger is performed, any one of the configured reference signal sets (corresponding to the above-mentioned A13 or A12), or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-persistent reference signals, and non-periodic reference signals.

[0259] Example 5: When D11 and D13 are configured for the target secondary cell, that is, when performing set triggering, any one of the configured reference signal sets (corresponding to the above-mentioned A13), or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-persistent reference signals, and non-periodic reference signals.

[0260] Example 6: When D12 and D13 are configured for the target secondary cell, that is, when a set trigger is performed, any one of the configured reference signal sets (corresponding to the above-mentioned A12 or A13) or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-persistent reference signals, and non-periodic reference signals.

[0261] Example 7: When D11, D12 and D13 are configured for the target secondary cell, that is, when the set trigger is performed, any one of the configured reference signal sets (corresponding to the above-mentioned A12 or A13) or any multiple ones (corresponding to the above-mentioned A11) can be triggered. This situation can be used for the transmission of periodic reference signals, semi-continuous reference signals, and non-periodic reference signals.

[0262] For example, taking a reference signal set that triggers sending once and repeating N as an example, Figure 4 As shown, when the secondary cell is activated, the reference signal set 1 which is repeatedly sent three times is triggered at the same time, and then the reference signal set 1 is repeatedly sent three times at the corresponding positions thereafter.

[0263] For example, for example, when multiple reference signal sets are sent once, Figure 5 As shown, after the secondary cell is activated, DCI is sent to trigger multiple reference signal sets, and then multiple reference signal sets are sent at corresponding positions thereafter.

[0264] The following takes the measurement of the Temporary CSI-RS for BM sent by the base station by the terminal as an example to illustrate the specific implementation of the embodiment of the present application as follows.

[0265] Application Scenario 1: Triggering of Periodic Temporary CSI-RS for BM

[0266] The specific implementation process includes:

[0267] Step 11: The base station configures a periodic Temporary CSI-RS for BM for the terminal on the Pcell through RRC. Since it is a periodic reference signal, only one reference signal may be configured, that is, the reference signal set includes only one reference signal, which simplifies the configuration of the reference signal. The configured IE is as follows:

[0268]

[0269]

[0270] Step 12: In the nth slot, the base station sends a MAC CE to activate Scell-1. The activation signaling format is as follows: Figure 6 As shown, C1 is 1, indicating that Scell-1 is activated.

[0271] Step 13-1, the terminal receives the MAC-CE sent by the base station, and the MAC-CE takes effect in the n+kth time slot. The terminal receives the Temporary CSI-RS for BM according to the period and offset configured in step 11 starting from the n+kth time slot.

[0272] That is to say, in this case, the triggering of the reference signal set is triggered by the MAC-CE for activating Scell-1 sent by the base station.

[0273] Step 13-2: The terminal receives Temporary CSI-RS for BM according to the period and time offset configured by the base station starting from the time slot configured by the base station RRC.

[0274] It should be noted that in this case, it can be regarded as that as long as the network device configures the periodic reference signal, the reference signal needs to be sent immediately and the terminal needs to receive the reference signal. That is to say, this case can be understood as the reference signal has been sent before activating Scell-1.

[0275] It should be noted that step 13-1 and step 13-2 are steps to be selected from.

[0276] Step 14: The terminal estimates L1-RSRP or L1-SINR for the received Temporary CSI-RS for BM, obtains the measurement report result, and reports it to the network device.

[0277] Application scenario 2: Triggering of semi-persistent Temporary CSI-RS for BM, terminating the sending of Temporary CSI-RS for BM by deactivating the MACCE of the Scell

[0278] The specific implementation process includes:

[0279] Step 21: The base station configures a semi-persistent Temporary CSI-RS for BM for the terminal on the Pcell through RRC. Since the semi-persistent reference signal can be configured with only one reference signal, similar to the periodic reference signal sending method, that is, the reference signal set includes only one reference signal, the configuration of the reference signal can be simplified. The configured IE is as follows:

[0280]

[0281] At the same time, the base station configures a sending period and an offset for the semi-persistent Temporary CSI-RS for BM, and the configuration signaling is the same as that in the first application scenario.

[0282] Step 22: In the nth slot, the base station sends a MAC CE to activate Scell-1. The activation signaling is the same as that in the first application scenario.

[0283] Step 23-1, the terminal receives the MAC-CE sent by the base station. This MAC-CE contains a field for activating the semi-persistent Temporary CSI-RS for BM. The field is used to indicate the reference signal set where the semi-persistent Temporary CSI-RS for BM is located. The MAC-CE takes effect in the n+kth time slot. Starting from the n+kth time slot, the terminal receives the Temporary CSI-RS for BM according to the period and offset configured in step 21.

[0284] Step 23-2, the terminal receives the MAC-CE that activates the Temporary CSI-RS for BM, and the MAC-CE takes effect in the n+kth time slot. The terminal receives the Temporary CSI-RS for BM according to the period and time offset configured in step 21 starting from the n+kth time slot.

[0285] It should be noted that step 23 - 1 and step 23 - 2 are steps to be selected from.

[0286] Step 24: The terminal performs L1-RSRP / L1-SINR estimation on the received Temporary CSI-RS for BM.

[0287] Step 25: In the n+mth time slot, the terminal receives the MAC-CE for deactivating Scell-1 sent by the base station. This MAC-CE takes effect in the n+m+1th time slot, and the terminal stops receiving Temporary CSI-RS for BM from the n+m+1+1th time slot.

[0288] Application 3: For the triggering of semi-persistent Temporary CSI-RS for BM, the termination condition is M slots after the MAC CE of the activated Scell ​​takes effect

[0289] The specific implementation process includes:

[0290] Step 31 to step 33 are the same as step 21 to step 23 of application scenario 2.

[0291] Step 34: The terminal performs L1-RSRP / L1-SINR estimation on the received Temporary CSI-RS for BM.

[0292] Step 35: The protocol stipulates that the sending of Temporary CSI-RS for BM ends 8 slots after the MAC CE of the activated Scell ​​takes effect.

[0293] Step 36: In the n+k+8th time slot, the terminal stops receiving Temporary CSI-RS for BM according to the protocol.

[0294] Application 4: For the triggering of semi-persistent Temporary CSI-RS for BM, the termination condition is the next slot when the base station receives beam reporting

[0295] The specific implementation process includes:

[0296] Step 41: The base station configures SerivingCellConfig->CSI-MeasConfig->CSI-ReportConfig for the terminal on the Pcell, where the carrier configuration is Scell ​​(CC2), indicating that the measurement resources used by the terminal for reporting are on the Scell.

[0297]

[0298]

[0299]

[0300] Step 42: The base station configures a semi-persistent Temporary CSI-RS for BM for the terminal on the Scell ​​through RRC. For configuration signaling, refer to step 21 of application scenario 2.

[0301] Step 43 is the same as step 22-step 23 in application scenario 2.

[0302] Step 44: The terminal performs L1-RSRP / L1-SINR estimation on the received Temporary CSI-RS for BM.

[0303] Step 45: The terminal reports the beam report of L1-RSRP / L1-SINR estimated in step 44, and the reporting resources use the resources indicated by semiPersistentOnPUSCH in the configuration signaling in step 41.

[0304] Step 46: The base station receives the measurement report result from the terminal, and according to the protocol, stops sending Temporary CSI-RS for BM in the next slot after receiving the measurement report result.

[0305] Application 5: For the triggering of aperiodic Temporary CSI-RS for BM, use one trigger to repeatedly send N Temporary CSI-RS for BM resource sets, and use the MAC CE of the activated Scell ​​to trigger the sending of aperiodic Temporary CSI-RS for BM

[0306] The specific implementation process includes:

[0307] Step 51: The base station configures a reference signal set of aperiodic Temporary CSI-RS for BM for the terminal through RRC, configures the number of repetitions N in the reference signal set, and the configured IE is as follows:

[0308]

[0309]

[0310] Step 52: In the nth slot, the base station sends a MAC CE to activate Scell ​​3. The activation signaling simultaneously activates the reference signal sets of 8 Temporary CSI-RS for BM in Scell. The reference signal sets of 8 Temporary CSI-RS for BM are repeatedly sent, and the time offset (offset_1, offset_2, offset_3, offset_4, offset_5, offset_6, offset_7, offset_8) of each repeated transmission is configured to the terminal through RRC.

[0311] The NZP-CSI-RS-ResourceSet corresponding to the activated Temporary CSI-RS for BM is indicated by the parameter scellActivationRS-Id-r17 configured by RRC. For example, the configured IE is as follows:

[0312]

[0313] Step 53: The terminal receives a MAC CE signaling instruction from the base station, and the MAC CE signaling takes effect in the n+kth time slot.

[0314] Step 54: The terminal receives a reference signal set at n+k+offset_1, n+k+offset_2, n+k+offset_3, ..., n+k+offset_8 according to the instruction of the base station.

[0315] Step 55: The terminal estimates L1-RSRP / L1-SINR for the received Temporary CSI-RS for BM, obtains the beam reporting result and reports it to the network device.

[0316] Application Scenario 6: For the triggering of aperiodic Temporary CSI-RS for BM, use one trigger to send N Temporary CSI-RS for BM resource, and use DCI to trigger the sending of aperiodic Temporary CSI-RS for BM

[0317] The specific implementation process includes:

[0318] Step 61: The base station configures a non-periodic Temporary CSI-RS for BM resource set and a Temporary CSI-RS for BM resource for the terminal through RRC, and configures the triggered time offset in the configuration of the Temporary CSI-RS for BM resource. The configured IE is as follows:

[0319]

[0320]

[0321] Step 62: In the nth slot, the base station sends a MAC CE for activating Scell, activates Scell3, and the MAC CE for activating Scell ​​takes effect in the n+kth time slot.

[0322] Step 63: In the pth slot, the Pcell sends DCI format 0_1, triggering the reference signal set to send non-periodic CSI-RS1 and CSI-RS3. The sending time of CSI-RS1 and CSI-RS3 is p+1 and p+3.

[0323] Step 64: The terminal receives CSI-RS1 and CSI-RS3 in the p+1th and p+3th time slots according to the instruction of the base station.

[0324] Step 65: The terminal estimates L1-RSRP / L1-SINR for the received CSI-RS1 and CSI-RS3, obtains the beam reporting result and reports it to the network device.

[0325] It should be noted that the embodiment of the present application provides a solution for reducing the activation delay by optimizing the FR2 Scell ​​beam scanning. By introducing a short-period reference signal, in the direction of the SSB level obtained by the FR1 Pcell beam scanning, the directional correlation between FR1 and FR2 is utilized, and a reference signal is configured around it for beam scanning to obtain the optimal beam information of the FR2 scell, thereby greatly reducing the activation delay of the FR2 Scell ​​(approximately 90% less time than using SSB).

[0328] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

[0330] like Figure 7 As shown, an embodiment of the present application provides a measurement reporting method, which is executed by a terminal and includes:

[0331] Step S701, obtaining a target reference signal set corresponding to a target secondary cell triggered by a network device through a primary cell;

[0332] It should be noted here that in the carrier aggregation scenario, the network device will configure a primary cell and one or more secondary cells for the terminal. The primary cell is always in an activated state, while the secondary cell may not always be in an activated state, but is activated when in use; the primary cell and the secondary cell are both located under the same network device (for example, a base station), and the secondary cell activation is triggered by the primary cell under the network device. When secondary cell activation is required, the specific secondary cell will send relevant reference signals to allow the terminal to perform beam measurement reporting.

[0333] It should be noted that the target reference signal is at least a part of the reference signal set in the reference signal set pre-configured for the target secondary cell. When the network device configures the reference signal set corresponding to the target secondary cell for the terminal, each reference signal set includes not only an indication of the reference signal (such as a reference signal index or number), but also includes reference signal sending-related indications, such as a sending time offset, a sending period, a sending method of the set (such as whether the set needs to be repeatedly transmitted, the number of repeated transmissions, etc.), etc. When the network device triggers the set to the terminal, it needs to notify the terminal which sets are triggered. After the terminal obtains which sets are triggered by the network device, it can know which reference signals need to be received and at which locations the corresponding reference signals need to be received; that is, the purpose of triggering the target reference signal set can be understood as notifying the terminal which reference signals to receive and the receiving location of the reference signals.

[0334] Optionally, the target reference signal set includes one of the following:

[0335] F11, multiple reference signal sets;

[0336] This situation can be understood as the primary cell needs to trigger multiple reference signal sets corresponding to the target secondary cell, that is, the target secondary cell needs to send reference signals in multiple reference signal sets to the terminal.

[0337] F12. A reference signal set is sent repeatedly N times, where N is an integer greater than or equal to 2;

[0338] This situation can be understood as the primary cell needs to trigger a reference signal set corresponding to the target secondary cell, and the reference signal in the reference signal set needs to be sent repeatedly N times, that is, the target secondary cell needs to send the reference signal in a reference signal set to the terminal multiple times.

[0339] F13, a reference signal set;

[0340] This situation can be understood as the primary cell only triggering one reference signal set corresponding to the target secondary cell, that is, the target secondary cell only needs to send a reference signal in one reference signal set to the terminal.

[0341] It should also be noted that the reference signal set mentioned in the embodiment of the present application includes at least one reference signal (RS). Optionally, the reference signal set can also be called a reference signal resource set (RS resource set), and the reference signal can also be called a reference signal resource (RS resource).

[0342] Step S702: receiving, according to the target reference signal set, a reference signal corresponding to the target secondary cell and sent by the network device through the target secondary cell;

[0343] Step S703: performing beam measurement reporting of the target secondary cell according to a reference signal corresponding to the target secondary cell;

[0344] The reference signal is associated with a synchronization signal block SSB used for beam measurement of the primary cell, and a transmission period of the reference signal is less than a transmission period of the SSB;

[0345] It should be noted that compared with the current secondary cell activation, the embodiment of the present application does not measure the SSB when activating the secondary cell, but a reference signal with a sending period less than the SSB, and the reference signal is associated with the SSB, for example, the reference signal and the SSB are quasi-co-sited (QCL), so that the delay occupied by the beam measurement during the secondary cell activation process can be reduced, and then the delay of the beam scanning can be reduced, thereby reducing the delay of the secondary cell activation.

[0346] Optionally, in an implementation manner, the acquiring a target reference signal set corresponding to a target secondary cell triggered by a network device through a primary cell includes:

[0347] A target reference signal set corresponding to the target secondary cell is obtained, which is triggered by the network device through the primary cell when or after the activation signaling of the target secondary cell is sent.

[0348] That is to say, the primary cell may trigger the target reference signal set at the same time when sending the activation signaling of the target secondary cell (for example, the activation signaling is the media access control control unit (MAC CE) for activating the secondary cell), that is, the operations of activating the target secondary cell and triggering the target reference signal set corresponding to the target secondary cell are both implemented through the activation signaling of the target secondary cell; the primary cell may also trigger the target reference signal set after sending the activation signaling of the target secondary cell, that is, first send the activation signaling of the target secondary cell, and then send specific signaling or specific information to trigger the target reference signal set corresponding to the target secondary cell. Optionally, the specific signaling may be a secondary cell beam measurement reference signal trigger signaling, for example, it may be a MAC CE for triggering a reference signal set; or, the specific information may also be secondary cell beam measurement reference signal control information, for example, it may be downlink control information (DCI) for triggering a reference signal set.

[0349] Optionally, in one implementation, the acquiring network device triggers a target reference signal set corresponding to the target secondary cell through the primary cell when the activation signaling of the target secondary cell is sent or after the activation signaling of the target secondary cell is sent, including the following:

[0350] H11. When the reference signal is a periodic reference signal, based on the activation signaling of the target secondary cell sent by the network device through the primary cell, determining a triggered target reference signal set corresponding to the target secondary cell;

[0351] It should be noted that when the network equipment adopts periodic reference signals, the target reference signal set corresponding to the target secondary cell can be triggered simultaneously when the target secondary cell is activated. That is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signal in the target reference signal set according to the pre-configured period and sending time offset, and the terminal also receives the reference signal according to the same period and sending time offset after receiving the activation signaling of the target secondary cell.

[0352] H12. When the reference signal is a semi-persistent reference signal, based on the activation signaling of the target secondary cell sent by the network device through the primary cell or the secondary cell beam measurement reference signal triggering signaling located after the activation signaling of the target secondary cell, determine the triggered target reference signal set corresponding to the target secondary cell;

[0353] It should be noted that, in the case where the network device adopts a semi-persistent reference signal, optionally, in one case, when the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered at the same time, that is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signals in the target reference signal set according to the sending period and sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signals according to the same period and sending time offset after receiving the activation signaling of the target secondary cell. Optionally, in another case, after the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal trigger signaling can be sent again, and then the target secondary cell sends the reference signals in the target reference signal set according to the sending period and sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signals according to the same period and sending time offset after receiving the secondary cell beam measurement reference signal trigger signaling.

[0354] It should also be noted here that when the secondary cell terminates the transmission of the reference signal, in order to avoid the overhead of the terminal detecting the reference signal, the network equipment needs to send a signal to the terminal through the secondary cell to terminate the transmission of the signal, so as to indicate to the terminal that the reference signal has stopped being sent. After receiving the signal, the terminal stops receiving the reference signal.

[0355] H13. When the reference signal is a non-periodic reference signal, determine the triggered target reference signal set corresponding to the target secondary cell based on the activation signaling of the target secondary cell sent by the network device through the main cell, the secondary cell beam measurement reference signal trigger signaling located after the activation signaling of the target secondary cell, or the secondary cell beam measurement reference signal control information located after the activation signaling of the target secondary cell.

[0356] It should be noted that, in the case where the network device adopts a non-periodic reference signal, optionally, in one case, when the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered at the same time, that is, after the activation signaling of the target secondary cell is sent, the target secondary cell can send the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the activation signaling of the target secondary cell. Optionally, in another case, after the target secondary cell is activated, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal trigger signaling can be sent again, and then the target secondary cell sends the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the secondary cell beam measurement reference signal trigger signaling. Optionally, in another case, after activating the target secondary cell, the target reference signal set corresponding to the target secondary cell can be triggered again, that is, after the activation signaling of the target secondary cell is sent, the secondary cell beam measurement reference signal control information can be sent again, and then the target secondary cell sends the reference signal in the target reference signal set according to the sending time offset corresponding to the target reference signal set, and the terminal also receives the reference signal according to the same sending time offset after receiving the secondary cell beam measurement reference signal control information.

[0357] Optionally, in one implementation, the secondary cell beam measurement reference signal trigger signaling, the activation signaling of the target secondary cell, or the secondary cell beam measurement reference signal control information includes one of the following:

[0358] I11. A bit map, wherein each bit in the bit map corresponds to a reference signal set, and each bit in the bit map is used to indicate whether the corresponding reference signal set is triggered or not;

[0359] It should be noted that in this case, each reference signal set configured for the target secondary cell corresponds to a bit, and the reference signal set to be triggered is set to the value of the corresponding bit to indicate the trigger. For example, 1 is used to indicate triggering the reference signal set, and 0 is used to indicate not triggering the reference signal set; or, 0 is used to indicate triggering the reference signal set, and 1 is used to indicate not triggering the reference signal set.

[0360] I12. Reference signal triggering state indication information, where the reference signal triggering state indication information is used to indicate one or more reference signal sets that are triggered;

[0361] It should be noted that in this case, a reference signal triggering status indication information is directly carried, and the indication information is used to indicate a triggered reference signal set. For example, the indication information is used to indicate the identification information (for example, a set number or index) of a triggered reference signal set.

[0362] Optionally, in one implementation, the method further includes:

[0363] receiving configuration information of a reference signal sent by a network device through the primary cell;

[0364] The acquiring a target reference signal set corresponding to a target secondary cell triggered by a network device through a primary cell includes:

[0365] In the configuration information, a target reference signal set corresponding to the target secondary cell and triggered by the network device through the primary cell is obtained, and the target reference signal set is included in the configuration information.

[0366] It should be noted that before using the reference signal set, it is necessary to configure the reference signal set first. When the main cell triggers the target reference signal set, it also selects from the pre-configured reference signal set to ensure that the terminal can accurately know which reference signal sets are triggered by the main cell, and ensure that the terminal can accurately receive the reference signal.

[0367] Optionally, in one implementation, the configuration information includes at least one of the following:

[0368] J11. A reference signal set corresponding to the target secondary cell, the reference signal set including at least one reference signal and a transmission time offset corresponding to each reference signal;

[0369] For example, a reference signal set including 64 reference signals is configured for the target secondary cell, and a corresponding transmission time offset is configured for each reference signal.

[0370] J12. multiple reference signal sets corresponding to the target secondary cell, each reference signal set including the number of repetitions of the reference signal set, at least one reference signal, and a transmission time offset corresponding to the reference signal set;

[0371] It should be noted that in this case, at least two reference signal sets are configured, and a number of repetition transmissions and a transmission time offset are configured for each reference signal set, indicating that the set needs to be repeatedly transmitted when being transmitted.

[0372] J13. Multiple reference signal sets corresponding to the target secondary cell, each of the reference signal sets including at least one reference signal and a transmission time offset corresponding to the reference signal set.

[0373] It should be noted that in this case, at least two reference signal sets are configured, each reference signal set is set with a corresponding transmission time offset, and the number of repeated transmissions of the set is not set in this case, indicating that the reference signal set does not need to be repeatedly transmitted during actual transmission.

[0374] It should be noted that all implementation methods in the above embodiments are applicable to the embodiments of the signal sending method applied to the network device side, and can achieve the same technical effect, which will not be repeated here.
