[0086] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102, wherein the network device includes at least one of the following: an access network device and a core network device.

[0087] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0088] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0089] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0090] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0091] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0092] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0093] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0094] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0095] In some embodiments, fifth-generation wireless networks (such as 5G networks) introduce massive MIMO (multiple input multiple output) technology, which enables simultaneous transmission to multiple terminals using the same time slot with minimal interference.

[0096] While MIMO offers excellent multiplexing gain, this technology does not solve the cell edge problem: when a terminal is located between a reference base station and an interfering base station, the terminal experiences a poor signal-to-interference-plus-noise ratio (SINR), requiring interference management algorithms, which ultimately reduces spectral efficiency. For example, the reference base station can be the base station corresponding to the terminal's serving cell, and the interfering base station can be the base station corresponding to the terminal's neighboring cell.

[0097] In some embodiments, to overcome the aforementioned cell edge problem, a non-cellular massive MIMO (CF mMIMO) network deployment can be adopted. In this case, the macro base stations in the traditional cellular network are replaced by access points (APs), which have fewer antennas and lower complexity compared to macro base stations.

[0098] For example, an access point (AP) can be connected to a central processing unit (CPU) via a wired or wireless connection. In this scenario, the CPU can refer to a device capable of processing and controlling the communication between the terminal and the AP, such as core network equipment or a control center. APs can use the same time frequency slots to jointly provide services to the terminal. For instance, wise association can be implemented between APs and terminals, ensuring that each terminal is served by a certain number of APs. For example, APs serving a terminal could be those closer to the terminal of interest or those with the highest large-scale fading coefficient. This deployment is also called "user-centric" because the set of APs serving a specific terminal forms a cluster centered around that terminal.

[0099] User-centric deployment of CF mMIMO can alleviate the aforementioned cell edge issues because, given the large number of distributed access points (APs), each terminal is likely to be located very close to at least one AP, thus ensuring good SINR and reliable connectivity. The CF-mMIMO architecture can serve as one of the key network architectures for 5G and above wireless networks (such as 6G networks).

[0100] From a network topology perspective, network architecture has roughly gone through the development stages of cellular technology, cooperative cellular technology, and distributed non-cellular technology. Throughout this evolution, the system has achieved increasingly wider coverage areas while eliminating interference between users. The user-centric deployment mentioned earlier can be seen as one specific application of distributed non-cellular technology.

[0101] In some embodiments, in a 5G communication system, beam-level Layer 1 (L1) measurements can be used for handover. However, L1 measurements are based on Layer 3 (L3) measurements, which are based on the cell level, and the procedure can be referenced, for example, to the relevant definitions in 3GPP Communication Protocol 38.300.

[0102] For network equipment, L3 measurements are first configured for multiple cells. Then, the terminal performs individual measurements on different cells, such as obtaining the Reference Signal Receiving Power (RSRP) by measuring the cell's reference signal. The RSRP can be L3-RSRP, which the terminal can then send to the network equipment. Upon receiving the L3-RSRP, the network equipment can select cells for further L1 measurements at the beam level. For example, it can identify cells with relatively good signal quality based on the L3-RSRP and instruct the terminal to perform L1 measurements on these cells.

[0103] As can be seen, beam measurement for traditional 5G communication networks involves two steps:

[0104] The first step is to measure the community level of multiple communities;

[0105] The second step is to perform beam level measurements on cells with relatively good cell quality.

[0106] However, in CF mMIMO network deployments, there is no concept of a cell; instead, there are multiple access points (APs). Therefore, it is necessary to clarify the beam measurement process in CF mMIMO network deployments.

[0107] Figure 2 is an interactive schematic diagram of a beam measurement method according to an embodiment of the present disclosure.

[0108] In some embodiments, the beam measurement method can be performed by a terminal, and the measurement object can include an access point in a CF mMIMO network deployment. For example, the terminal can measure the beam of the access point.

[0109] As shown in Figure 2, the beam measurement method may include the following steps:

[0110] In step S201, an indication message sent by a network device is received, wherein the indication message is used to instruct the access point under test to be measured;

[0111] In step S202, at least one reference signal on at least one beam of the access point to be tested is measured to obtain measurement information;

[0112] In step S203, measurement information is sent to the network device.

[0113] In some embodiments, the network device may be an access point (e.g., an access point under test or another access point in the network), or a CPU to which the access point is connected via wired or wireless means.

[0114] In some embodiments, the indication information may instruct the terminal to perform measurements on the access point under test. The indication information may be sent via broadcast or unicast, and this disclosure is not limited in this regard.

[0115] In some embodiments, the access point under test (APD) may transmit at least one beam, and the beam may carry at least one reference signal. For example, in at least one beam, one beam may carry one reference signal, or in at least one beam, one beam may carry multiple reference signals. The types of reference signals carried by different beams may be the same or different, and this disclosure is not limiting in this regard.

[0116] For example, the type of reference signal can be a Channel State Information Reference Signal (CSI-RS), or a Synchronization Signal Block (SSB), or other reference signals; this disclosure does not limit this.

[0117] According to embodiments of this disclosure, in a user-centric deployment (e.g., a CF mMIMO network deployment), a terminal can measure the reference signal in the beam of the access point under test based on indication information from the network device, and send the measured measurement information to the network device. Accordingly, this clarifies the beam measurement and reporting process of the terminal in a user-centric deployment, i.e., in the absence of a cell, so that the network device can promptly obtain information about the signal quality of the access point under test.

[0118] In some embodiments, the measurement delay of the terminal for the access point under test is equal to: the first duration for which the terminal measures at least one reference signal on at least one beam of the access point under test to obtain measurement information, for example, the first duration can be denoted as T. measure .

[0119] In some embodiments, the first duration can be determined by the network device based on the capability information (e.g., processing capability, radio frequency capability, etc.) reported by the terminal, or by the manufacturer of the terminal or network device. For example, the first duration can be determined by simulating the communication process described in the embodiments of this disclosure.

[0120] In some embodiments, the access point under test transmits at least one reference signal through at least one beam, which may involve transmitting one reference signal through a single beam. In this case, the first duration for the terminal to measure the at least one reference signal on at least one beam of the access point under test to obtain measurement information can be denoted as T. measure1 .

[0121] In some embodiments, the access point under test transmits at least one reference signal through at least one beam, or multiple reference signals may be transmitted through one beam. In this case, the first duration for the terminal to measure at least one reference signal on at least one beam of the access point under test to obtain measurement information can be denoted as T. measure2 .

[0122] In some embodiments, the access point under test transmits at least one reference signal via at least one beam, or transmits the reference signal via multiple beams, with each beam carrying one reference signal. In this case, the first duration for the terminal to measure at least one reference signal on at least one beam of the access point under test to obtain measurement information can be denoted as T. measure3 .

[0123] In some embodiments, the access point under test transmits at least one reference signal through at least one beam, or transmits the reference signal through multiple beams, with each beam carrying multiple reference signals. In this case, the first duration for the terminal to measure at least one reference signal on at least one beam of the access point under test to obtain measurement information can be denoted as T, for example. measure4 .

[0124] It should be noted that T in the previous embodiments measure1 T measure2 T measure3 T measure4 The duration can be determined by the manufacturer to be the same, or by the network device based on the capability information reported by the terminal to be the same; or, the duration can be determined by the manufacturer to be different, or by the network device based on the capability information reported by the terminal to be different.

[0125] In some embodiments, the network device can determine, based on a first duration, that from the start of sending the first instruction information to the terminal, the terminal can wait for a first duration before sending measurement information to the network device. This helps ensure that the network device determines the timing of receiving the measurement information based on the first duration, so as to successfully receive the measurement information.

[0126] In some embodiments, the beam measurement method further includes at least one of the following:

[0127] The identifier of the access point to be tested is detected;

[0128] Synchronize time and frequency with the access point under test.

[0129] It should be noted that for the terminal, the two steps of detecting the identifier of the access point under test and synchronizing with the access point under test in time and frequency are not mandatory. For example, both steps can be performed, only one step can be performed, or neither step can be performed.

[0130] In some embodiments, the indication information indicates the identifier of a specific access point to be tested. In this case, the access point to be tested is known to the terminal, and it is not necessary to perform the detection of the identifier of the access point to be tested.

[0131] In some embodiments, the indication information indicates the frequency domain information of the access point to be tested. For the terminal, it only knows the frequency of the access point to be tested and needs to further perform the operation of detecting the identifier of the access point to be tested in order to determine the specific access point to be tested.

[0132] For example, the terminal can search for access points at the frequencies corresponding to the frequency domain information. For the access points found, it can identify the access points with relatively large signal strength (e.g., greater than the signal strength threshold) and use the access points corresponding to these identifiers as the access points to be tested.

[0133] In some embodiments, once the access point under test is identified, the terminal can perform time-frequency synchronization with the access point under test in order to accurately measure the reference signal transmitted by the access point under test via the beam.

[0134] In some embodiments, if the terminal has already synchronized with the access point under test in terms of time and frequency, and it is necessary to perform beam measurement on these access points under test again in the future, if the terminal position has not changed significantly (e.g., the displacement is within the distance threshold range), and the position of the access point under test is fixed, it can be assumed that the terminal and the access point under test are still in time and frequency synchronization, so it is not necessary to perform time and frequency synchronization with the access point under test again.

[0135] In some embodiments, in order to determine the access point to be tested, such as determining the identifier of the access point to be tested and the frequency domain information of the access point to be tested in the above embodiments, the network device may first obtain the location information of the terminal.

[0136] For example, a terminal can send its location information to a network device.

[0137] For example, network devices can detect the location information of terminals.

[0138] For example, if a network device detects the location information of a terminal, the terminal does not need to send its location information back to the network device. Conversely, if the terminal sends its location information to the network device, the network device does not need to detect the terminal's location information.

[0139] For example, after determining the location information of the terminal, the network device can select an access point near the location of the terminal (e.g., within a range where the distance between the terminal and the access point is less than a distance threshold) as the access point to be tested.

[0140] In some embodiments, the measurement delay of the terminal on the access point under test is equal to one of the following:

[0141] The first duration for which the terminal measures at least one reference signal on at least one beam of the access point under test to obtain measurement information, and the second duration for which the terminal detects the identifier of the access point under test;

[0142] The first duration for which the terminal measures at least one reference signal on at least one beam of the access point under test to obtain measurement information is the sum of the first duration and the third duration for which the terminal and the access point under test perform time-frequency synchronization.

[0143] The terminal measures at least one reference signal on at least one beam of the access point under test to obtain the measurement information, which is the first duration, the sum of the second duration and the third duration.

[0144] In some embodiments, it is a necessary step for the terminal to measure and report the reference signal carried by the beam of the access point under test. Therefore, the first duration is necessarily present in the measurement delay of the access point under test by the terminal.

[0145] As the analysis above shows, detecting the identifier of the access point under test and synchronizing time and frequency with the access point under test are optional steps. For example, the duration for the terminal to detect the identifier of the access point under test is the second duration (e.g., denoted as T). AP_detection The duration for time-frequency synchronization between the terminal and the access point under test is the third duration (e.g., denoted as T). sync ).

[0146] For example, when the terminal needs to detect the identifier of the access point under test, the measurement delay of the access point under test (e.g., denoted as T) is... delay The first duration is equal to the second duration, which is T. delay =T measure +T AP_detection .

[0147] For example, when the terminal needs to synchronize its time and frequency with the access point under test, the measurement delay of the terminal for the access point under test is equal to the first duration plus the third duration, i.e., T. delay =T measure +Tsync .

[0148] For example, when the terminal needs to detect the identifier of the access point under test and synchronize its time and frequency with the access point under test, the measurement delay of the terminal for the access point under test is equal to the sum of the first duration and the second and third durations, i.e., T. delay =T measure +T AP_detection +T sync .

[0149] It should be noted that time-frequency synchronization between the terminal and the access point under test can include two levels of precision, such as time-frequency synchronization with a first precision and time-frequency synchronization with a second precision, where the second precision is higher than the first precision. For example, the duration of time-frequency synchronization with the first precision is denoted as T. sync_rough The duration of time-frequency synchronization with the second synchronization precision performed by the terminal is denoted as T. sync_fine So T sync It can be equal to T sync_rough , or equal to T sync_fine , or equal to T sync_rough With T sync_fine sum.

[0150] In some embodiments, the type of the access point to be tested includes at least one of the following:

[0151] An access point with one antenna;

[0152] Access points with multiple antennas.

[0153] For example, an access point with one antenna can transmit a beam in all directions (e.g., 0 to 360 degrees) through that antenna. In this case, the signal strength of the reference signal in the beam can be considered the same in every direction of the access point.

[0154] For example, an access point with multiple antennas can transmit beams in different directions using different antennas. In this case, due to the differences between the antennas, the signal strength of the reference signal in the beam is not equal in different directions of the access point.

[0155] Considering the aforementioned characteristics of access points with one antenna and access points with multiple antennas, the terminal can adopt different measurement methods when the access point under test is an access point with one antenna and when the access point under test is an access point with multiple antennas.

[0156] In some embodiments, the access point under test is an access point with one antenna, and the indication information is also used to indicate that a first measurement accuracy measurement is performed on the access point under test.

[0157] Figure 3 is a schematic diagram of an access point under test according to an embodiment of the present disclosure.

[0158] As shown in Figure 3, there are multiple access points and multiple terminals in a CF mMIMO network deployment. For example, for terminal #1, the determined access points to be tested are those within a first distance range (e.g., range #1) that are less than the distance to terminal #1, such as AP#1, AP#2, AP#3, AP#4, and AP#5 in Figure 3. These five access points are access points with one antenna each.

[0159] When the access point under test is an access point with one antenna, since the intensity of the reference signal in the beam is considered the same in each direction when the access point transmits a beam through one antenna, the intensity of the reference signal in the beam received by the terminal in different directions of the access point is also the same.

[0160] In this scenario, the terminal can perform a rough measurement of the reference signal carried by the beam of the access point under test, for example, with a first measurement accuracy. Here, "the terminal performs the measurement with the first measurement accuracy" means that the terminal measures the reference signal in the beam of the access point under test over a relatively large angular range. Because the intensity of the reference signal in the beam of the access point under test is the same in every direction, it is not necessary to measure the reference signal in the beam of the access point under test separately over a relatively small angular range.

[0161] In some embodiments, the type of the access point under test is an access point with multiple antennas, and the indication information is also used to indicate one of the following:

[0162] First, the access points belonging to the first set of the access points to be tested are measured with a first measurement accuracy, and then the access points belonging to the second set of the access points to be tested are measured with a second measurement accuracy.

[0163] The access points belonging to the second set of the access points to be tested are measured with a second measurement accuracy; wherein the second measurement accuracy is higher than the first measurement accuracy.

[0164] In some embodiments, the distance from the access point in the first set to the terminal is greater than the distance from the access point in the second set to the terminal.

[0165] Figure 4 is a schematic diagram of another access point to be tested according to an embodiment of the present disclosure.

[0166] As shown in Figure 4, in a CF mMIMO network deployment, there are multiple access points and multiple terminals. For example, for terminal #1, the determined access points to be tested are those within a first distance range (e.g., range #1) that are less than the distance to terminal #1, such as AP#1, AP#2, AP#3, AP#4, AP#5, AP#6, AP#7, AP#8, and AP#9 in Figure 4. These nine access points are access points with multiple antennas.

[0167] Among these 9 access points, AP#1, AP#2, AP#3, and AP#4 are relatively close to the terminal, so these 4 access points can be grouped into the first set. AP#5, AP#6, AP#7, AP#8, and AP#9 are relatively far from the terminal, for example, the distance to terminal #1 is less than the second distance (for example, denoted as range #2), so these 5 access points can be grouped into the second set.

[0168] For example, the terminal can use access points in both the first set and the second set as access points to be measured. In this case, the terminal can first measure the access points belonging to the first set with a first measurement accuracy, and then measure the access points belonging to the second set with a second measurement accuracy.

[0169] For example, the terminal may only measure the access points in the second set as the access points to be tested. In this case, the terminal performs a second measurement accuracy measurement on the access points in the second set of the access points to be tested.

[0170] Because there are multiple antenna access points, the signal strength of the reference signal in the beam is not equal in different directions. In order to accurately measure the reference signal in the beam of the access point under test, the terminal can perform the measurement with a relatively high precision (e.g., a second measurement precision). Here, the terminal performing the measurement with the second measurement precision can mean that the terminal measures the reference signal in the beam of the access point under test within a relatively small angular range.

[0171] For example, for the access points under test in the first set, since these access points are far from the terminal, if the terminal performs measurements based on the second measurement accuracy, it will be difficult to determine the beam with relatively good signal quality in a few attempts. Therefore, the terminal can perform measurements based on the first measurement accuracy. Since measurements based on the first measurement accuracy are performed at relatively large angles, the beam with relatively good (e.g., optimal) signal quality can be determined in a fewer attempts. Accordingly, it is beneficial to ensure that the terminal quickly determines the beam with optimal signal quality and sends the measurement information of the reference signal of the beam with optimal signal quality to the network device.

[0172] It should be noted that for the access point under test in the first set, after the terminal performs measurement based on the first measurement accuracy, it can also perform measurement based on the second measurement accuracy. The reason is that the beam determined by measurement based only on the first measurement accuracy may not be the best beam actually transmitted by the access point under test, but rather the angle range where the best beam is located. Within this angle range, further measurement based on the second measurement accuracy is beneficial to accurately determine the best beam.

[0173] For example, for the access points under test in the second set, since these access points are relatively close to the terminal, the terminal can determine the beam with relatively good signal quality in fewer measurements based on the second measurement accuracy. Therefore, the terminal directly measures based on the second measurement accuracy. This helps ensure that the terminal quickly determines the beam with the best signal quality and sends the measurement information of the reference signal of the beam with the best signal quality to the network equipment.

[0174] In some embodiments, where the indication information is further used to instruct that access points belonging to a first set of access points under test be measured with a first measurement accuracy first, and then access points belonging to a second set of access points under test be measured with a second measurement accuracy, time-frequency synchronization with the access points under test includes:

[0175] First, perform time-frequency synchronization with the access points belonging to the first set of the access points under test at the first synchronization accuracy, and then perform time-frequency synchronization with the access points belonging to the second set of the access points under test at the second synchronization accuracy.

[0176] For example, if the instruction information is used to instruct that access points belonging to the first set of access points to be tested be measured with a first measurement accuracy first, and then access points belonging to the second set of access points to be tested be measured with a second measurement accuracy, the terminal needs to perform two measurement operations: one to measure the access points in the first set, and the other to measure the access points in the second set.

[0177] In this situation, in order to ensure that each measurement can be executed smoothly, the terminal needs to perform a time-frequency synchronization operation before each measurement operation.

[0178] For measurement operations with relatively low precision, the precision of time-frequency synchronization can also be relatively low; for measurement operations with relatively high precision, the precision of time-frequency synchronization can also be relatively high.

[0179] For example, the terminal first performs time-frequency synchronization with the access points belonging to the first set of the access points under test with a first synchronization accuracy, and then performs measurement with the access points belonging to the first set of the access points under test with a first measurement accuracy; next, it first performs time-frequency synchronization with the access points belonging to the second set of the access points under test with a second synchronization accuracy, and then performs measurement with the access points belonging to the second set of the access points under test with a second measurement accuracy.

[0180] In some embodiments, the third duration is equal to the sum of the duration of time-frequency synchronization with the access point under test at the first synchronization accuracy and the duration of time-frequency synchronization with the access point under test at the second synchronization accuracy, for example, it can be denoted as T. sync =T sync_rough +T sync_fine .

[0181] In some embodiments, when the indication information is further used to instruct access points belonging to the second set of access points under test to perform a second measurement accuracy measurement, time-frequency synchronization with the access points under test includes:

[0182] Time and frequency synchronization with the access points belonging to the second set of the access points under test is performed with the second synchronization accuracy.

[0183] For example, if the indication information is used to instruct the access points belonging to the second set of the access points to be tested to perform a second measurement accuracy, the terminal needs to perform a measurement operation, that is, to measure the access points in the second set.

[0184] In this scenario, to ensure successful measurement execution, the terminal needs to perform time-frequency synchronization before the measurement operation. For measurement operations requiring relatively high precision, the time-frequency synchronization precision can also be relatively high.

[0185] For example, the terminal first performs time-frequency synchronization with the access points belonging to the second set of the access points under test at the second synchronization accuracy, and then performs measurement with the second measurement accuracy on the access points belonging to the second set of the access points under test.

[0186] In some embodiments, the measurement delay of the terminal to the access point under test is equal to one of the following: the third duration is equal to the duration of time-frequency synchronization between the terminal and the access point under test with the second synchronization accuracy, for example, it can be denoted as T. sync =T sync_fine .

[0187] Figure 5 is an interactive schematic diagram illustrating another beam measurement method according to an embodiment of the present disclosure.

[0188] As shown in Figure 5, in step S501, the terminal can send its location information to the network device.

[0189] It should be noted that step S501 is optional. For example, when the network device detects the location information of the terminal, it may not need to execute step S501.

[0190] Measurement phase #1 may include steps S502 to S505.

[0191] In step S502, the network device selects access points from set #A, for example, set #A can be the first set in the above embodiment.

[0192] In step S503, the network device configures the terminal to measure the access points in set #A.

[0193] In step S504, the terminal measures the access points in set #A based on the first measurement accuracy to obtain the first measurement result.

[0194] In step S505, the terminal sends the first measurement result to the network device.

[0195] Measurement phase #2 may include steps S506 to S509.

[0196] In step S506, the network device selects access points from set #B, for example, set #B can be the second set in the above embodiment.

[0197] In step S507, the network device configures the terminal to measure the access points in set #B.

[0198] In step S508, the terminal measures the access points in set #B based on the second measurement accuracy to obtain the second measurement result.

[0199] In step S509, the terminal sends the second measurement result to the network device.

[0200] It should be noted that both measurement stage #1 and measurement stage #2 mentioned above are optional.

[0201] For example, if the access point is an access point with one antenna, the access point does not need to be divided into two sets, but can be divided into only set #A. In this case, only measurement phase #1 is necessary.

[0202] For example, when the type of access point to be tested is an access point with multiple antennas, the access points can be divided into two sets. For example, set #A is the first set in the above embodiment, and set #B is the second set in the above embodiment. Then, when the indication information instructs the terminal to perform a second measurement accuracy measurement on the access points belonging to the second set of the access points to be tested, the terminal only needs to execute measurement stage #2.

[0203] For example, in measurement phase #1, the duration of time-frequency synchronization for the terminal to achieve the first synchronization accuracy is T. sync_rough If the terminal executes step S501 and measurement phase #1, but does not execute measurement phase #2, the network device can determine T. delay =T measure +T AP_detection +T sync_rough If the terminal performs measurement phase #1 but does not perform step S501 or measurement phase #2, the network device can determine T. delay =T measure +T sync_rough .

[0204] For example, in measurement phase #2, the duration of time-frequency synchronization for the terminal to achieve the first synchronization accuracy is T. sync_fine If the terminal performs measurement stage #2 without executing step S501 and measurement stage #1, the network device can determine T. delay =T measure +T sync_fine If the terminal performs measurement phase #1 and measurement phase #2, but does not perform step S501, the network device can determine T. delay =T measure +T sync_rough +T sync_fine .

[0205] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S203. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, step S203 may be implemented as an independent embodiment, step S201+S202 may be implemented as an independent embodiment, step S201+S203 may be implemented as an independent embodiment, step S202+S203 may be implemented as an independent embodiment, and step S201+S202+S203 may be implemented as an independent embodiment, but is not limited thereto.

[0206] In some embodiments, steps S201, S202, and S203 may be performed in an interchangeable order or simultaneously.

[0207] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0208] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0209] In some embodiments, step S203 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0210] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0211] Firstly, embodiments of this disclosure provide an information sending method. Figure 6 is a schematic flowchart illustrating an information sending method according to an embodiment of this disclosure. The information sending method shown in this embodiment can be executed by a terminal.

[0212] As shown in Figure 6, the information sending method may include the following steps:

[0213] In step S601, an indication message sent by a network device is received, wherein the indication message is used to instruct the access point under test to be measured;

[0214] In step S602, at least one reference signal on at least one beam of the access point to be tested is measured to obtain measurement information;

[0215] In step S603, measurement information is sent to the network device.

[0216] It should be noted that the embodiment shown in Figure 6 can be implemented independently or in combination with at least one other embodiment in this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope.

[0217] In some embodiments, the measurement delay of the terminal for the access point under test is equal to the first duration for the terminal to measure at least one reference signal on at least one beam of the access point under test to obtain measurement information.

[0218] In some embodiments, the information transmission method further includes at least one of the following: detecting the identifier of the access point under test; and performing time-frequency synchronization with the access point under test.

[0219] In some embodiments, the measurement delay of the terminal on the access point under test is equal to one of the following:

[0220] The first duration for which the terminal measures at least one reference signal on at least one beam of the access point under test to obtain measurement information, and the second duration for which the terminal detects the identifier of the access point under test;

[0221] The first duration for which the terminal measures at least one reference signal on at least one beam of the access point under test to obtain measurement information is the sum of the first duration and the third duration for which the terminal and the access point under test perform time-frequency synchronization.

[0222] The terminal measures at least one reference signal on at least one beam of the access point under test to obtain the measurement information, which is the first duration, the sum of the second duration and the third duration.

[0223] In some embodiments, the type of access point to be tested includes at least one of the following: an access point having one antenna; an access point having multiple antennas.
