Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

That is, in the embodiments of the present disclosure, the term "and/or" describes an association relationship of an association object, which means that there may be three relationships, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Network coverage is related to beam scene planning of SSB (for example, SSB beam planning scenes have hundreds of scenes, such as high-rise scenes, dense stadium coverage, rural suburb coverage, etc.), basic parameter planning of each access network device (for example, height, longitude and latitude, mechanical downtilt angle, electrical downtilt angle, horizontal central angle, transmission power, etc.) and the like, so network planning and optimization are extremely complex and time-consuming, labor-consuming, personnel-consuming, and money-consuming things.

When the network provisioning is complete, it is important how to test the coverage performance of the network.

In the related art, the coverage performance of the downlink beam of the serving cell or the SSB is determined by a network pulling method, that is, the network is pulled according to the road and the floor covered by the access network device by the drive test, the average RSRP, SINR distribution, etc. of the SSB in the serving cell of the access network device are obtained according to the log of the terminal device, and then the coverage performance of the downlink beam of the serving cell is approximately determined according to the coverage distance, the frequency band and the existing accumulated data of the serving cell. The above process may have iteration, for example, after adjusting part of parameters, a new round of network pulling needs to be performed, updated data is obtained again, and then the downlink beam coverage performance of the serving cell is determined according to the obtained data.

However, in the above manner, there are at least the following problems:

first, it requires a lot of manpower, time and money to test the coverage performance of the downlink beam of the serving cell, which is not only inefficient but also costly, and in addition, it requires a lot of manpower resources to analyze the acquired data.

Second, it relies on existing empirical data and the manual experience of the tester. For example, the path loss in different frequency bands and different scenes can have larger difference, and in a certain distribution scene, the RSRP of a certain point location is not accurately expected, and more depends on the manual experience of a tester.

Third, the limited number of samples affects the accuracy of the test results, even for some cells, the point locations in the corresponding coverage area cannot be tested.

In view of at least one problem existing in the foregoing, an embodiment of the present disclosure provides a method, an apparatus, an access network device, and a medium for determining coverage performance of a downlink beam.

The following describes a method, an apparatus, an access network device, and a storage medium for determining coverage performance of a downlink beam in this embodiment with reference to the accompanying drawings.

A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be configured to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiments of the present disclosure may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), relay node (relay node), home base station (femto), pico base station (pico), etc., which are not limited in the embodiments of the present disclosure. In some network structures, the base station may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

The terminal device may be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem, among others. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN for short), and may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as Personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal Digital Assistants (PDA) DIGITAL ASSISTANT, and the like.

As shown in fig. 1, the method for determining the coverage performance of the downlink beam may include the following steps:

Step 101, obtaining the downlink beam gain of the access network equipment.

In the embodiment of the present disclosure, the downlink beam gain of the access network device may be determined according to the antenna configuration information of the access network device, or may be determined according to uplink path loss (denoted as reference uplink path loss in the present disclosure) and downlink path loss (denoted as reference downlink path loss in the present disclosure) of a plurality of cells or a plurality of access network devices (denoted as reference access network devices).

Step 102, obtaining an uplink path loss and a downlink path loss of the access network device, and determining a first difference between the uplink path loss and the downlink path loss.

The first difference may also be referred to as a path loss difference (pathloss _dis), and may be a difference between an uplink path loss and a downlink path loss, an absolute value of the difference, or the like.

In the embodiment of the disclosure, the uplink path loss of the access network device may be obtained, the downlink path loss of the access network device may be obtained, and the first difference between the uplink path loss and the downlink path loss of the access network device may be calculated.

As an example, the first difference = uplink loss of the access network device-downlink loss of the access network device.

It should be noted that, the execution timing of steps 101 and 102 is not limited, and the present embodiment is only exemplified by step 102 being executed after step 101, and in practical application, step 102 may be executed before step 101, or step 102 may be executed in parallel with step 101.

Step 103, determining whether the coverage performance of the downlink beam in the service cell corresponding to the access network device meets the set requirement according to the first difference and the downlink beam gain.

In the disclosed embodiments, the set requirements may be used to indicate that coverage performance is good.

In the embodiments of the present disclosure, the coverage performance of the downlink beam may be used to indicate RSRP distribution, SINR distribution, etc. within the coverage area of the downlink beam.

In the embodiment of the present disclosure, whether the coverage performance of the downlink beam in the serving cell corresponding to the access network device meets the set requirement may be determined according to the first difference and the downlink beam gain.

As an example, when the first difference is greater than the downlink beam gain, it may be determined that the coverage performance of the downlink beam in the serving cell corresponding to the access network device is relatively better, and at this time, it may be determined that the coverage performance of the downlink beam in the serving cell corresponding to the access network device meets the set requirement.

And when the first difference is smaller than or equal to the downlink beam gain, determining that the coverage performance of the downlink beam in the service cell corresponding to the access network device is relatively poor, and at this time, determining that the coverage performance of the downlink beam in the service cell corresponding to the access network device does not meet the set requirement.

The method for determining the coverage performance of the downlink beam in the embodiment of the disclosure obtains the gain of the downlink beam of the access network equipment; acquiring uplink path loss and downlink path loss of access network equipment, and determining a first difference between the uplink path loss and the downlink path loss; and determining whether the coverage performance of the downlink wave beam in the service cell corresponding to the access network equipment meets the set requirement or not according to the first difference and the downlink wave beam gain. Therefore, the coverage performance of the downlink wave beam in the service cell can be tested based on the difference between the uplink and downlink path loss of the access network equipment, manual intervention is not needed, the testing efficiency can be improved, and the labor and time cost can be reduced.

In order to clearly illustrate how the downlink beam gain of the access network device is determined in any embodiment of the present disclosure, the present disclosure further proposes a method for determining the coverage performance of the downlink beam.

Fig. 2 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 2, the method for determining the coverage performance of the downlink beam may include the following steps:

step 201, obtaining antenna configuration information of access network equipment.

The antenna configuration information may include the number of antennas, the antenna configuration, the horizontal pitch of the antennas (or the horizontal pitch of the oscillators), the vertical pitch of the antennas (or the vertical pitch of the oscillators), the number of vertical oscillators, the number of horizontal oscillators, the horizontal bandwidth and the vertical bandwidth of a single oscillator, and the like.

In the embodiment of the present disclosure, antenna configuration information of an access network device may be obtained.

Step 202, determining the reference beam gain of the access network equipment according to the antenna configuration information.

The reference beam gain may also be referred to herein as a theoretical beam gain.

In the embodiment of the disclosure, the reference beam gain of the access network device may be determined according to the antenna configuration information.

As an example, the antenna morphology is: m (number of rows of antenna array) ×n (number of columns of antenna array) ×p (number of polarization directions), the reference beam gain may be: log ₁₀ (m×n) is 10×log. For example, when the number of antennas is 64, m=4, n=8, p=2, and reference beam gain=10×log ₁₀ (8*4) =15 dB.

Step 203, acquiring the set back-off beam gain.

In the embodiment of the present disclosure, the back-off beam gain is a preset gain value, for example, the back-off beam gain may be 3dB.

Step 204, determining the downlink beam gain of the access network device according to the reference beam gain and the back-off beam gain.

Where the downstream beam gain may also be referred to as the actual beam gain. For example, the downlink beam gain is marked bf_gain.

In the embodiment of the disclosure, the downlink beam gain of the access network device may be determined according to the reference beam gain and the back-off beam gain.

As an example, the difference between the reference beam gain and the back-off beam gain may be used as the downlink beam gain for the access network device.

In one possible implementation manner of the embodiment of the present disclosure, the downlink beam gain of the access network device may be calculated by:

1. And determining the horizontal resolution and the vertical resolution of the antenna according to the antenna configuration information.

In the embodiment of the disclosure, the horizontal resolution of the antenna and the vertical resolution of the antenna may be determined according to the antenna configuration information of the access network device.

As an example, the horizontal resolution of the antenna may be determined according to the number of horizontal elements, the horizontal bandwidth of a single element, and the horizontal spacing of the antenna.

For example, horizontal resolution is approximately equal to the horizontal bandwidth of a single element/(the number of horizontal elements is equal to the horizontal pitch of the antenna) ×wavelength/2. For example, when the antenna is 4 (row, number of vertical elements) ×8 (column, number of horizontal elements) ×2 (dual polarization), the horizontal pitch of the antenna is 0.5 wavelength, and the horizontal bandwidth of a single element is 120 degrees, the horizontal resolution is 15 °.

As an example, the vertical resolution of an antenna may be determined based on the number of vertical elements, the vertical bandwidth of a single element, and the vertical spacing of the antenna.

For example, horizontal resolution is approximately equal to the horizontal bandwidth of a single element/(the number of horizontal elements is equal to the horizontal pitch of the antenna) ×wavelength×2. For example, when the antenna configuration is 4 (row, number of vertical elements) ×8 (column, number of horizontal elements) ×2 (dual polarization), the vertical pitch of the antenna is 1.9 wavelength, and the vertical bandwidth is 25 degrees, the vertical resolution is 6 °.

2. The horizontal beam width and the vertical beam width of the SSB in the serving cell are acquired.

In the embodiments of the present disclosure, the horizontal beam width of the SSB and the vertical beam width of the SSB in the serving cell may be acquired.

3. In the case that the difference between the horizontal beam width and the horizontal resolution is smaller than a set first difference threshold and/or the difference between the vertical beam width and the vertical resolution is smaller than a set second difference threshold, the downstream beam gain is determined according to the reference beam gain and the back-off beam gain.

The first difference threshold and the second difference threshold are smaller preset values, and the magnitude relation between the first difference threshold and the second difference threshold is not limited, for example, the first difference threshold may be greater than the second difference threshold, or the first difference threshold may be smaller than the second difference threshold, or the first difference threshold may be equal to the second difference threshold.

In the embodiment of the present disclosure, in the case where a difference (such as a difference value, an absolute value of a difference value, etc.) between the horizontal beam width of the SSB and the horizontal resolution of the antenna is smaller than a set first difference threshold value, and/or a difference (such as a difference value, an absolute value of a difference value, etc.) between the vertical beam width of the SSB and the vertical resolution of the antenna is smaller than a set second difference threshold value, the downstream beam gain may be determined according to the reference beam gain and the back-off beam gain.

4. And determining the downlink beam gain according to the set multiples of the reference beam gain and the back-off beam gain under the condition that the horizontal beam width is the set multiples of the horizontal resolution and/or the vertical beam width is the set multiples of the vertical resolution.

The set multiple is a preset multiple, for example, the set multiple may be 2 times.

In the embodiment of the present disclosure, in the case where the horizontal beam width of the SSB is a set multiple of the horizontal resolution of the antenna, and/or the vertical beam width of the SSB is a set multiple of the vertical resolution of the antenna, the downlink beam gain may be determined according to the set multiple of the reference beam gain and the back-off beam gain.

As an example, downstream beam gain = reference beam gain-back-off beam gain set multiple.

It should be noted that, the step 3 and the step 4 are two parallel implementation methods, and only one implementation method is needed in actual application.

When there are multiple SSBs in the serving cell, the downlink beam gain corresponding to each SSB may be determined according to the step 3 or the step 4, so that the downlink beam gain of the access network device may be determined according to the downlink beam gain of each SSB. For example, the average of the downstream beam gains of multiple SSBs may be used as the downstream beam gain of the access network device.

Step 205, obtaining an uplink path loss and a downlink path loss of the access network device, and determining a first difference between the uplink path loss and the downlink path loss.

Step 206, determining whether the coverage performance of the downlink beam in the service cell corresponding to the access network device meets the set requirement according to the first difference and the downlink beam gain.

The explanation of steps 205 to 206 may be referred to the relevant descriptions in any embodiment of the disclosure, and are not repeated here.

The method for determining the coverage performance of the downlink beam can effectively determine the downlink beam gain of the access network equipment according to the antenna configuration information of the access network equipment.

Fig. 3 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 3, the method for determining the coverage performance of the downlink beam may include the following steps:

Step 301, obtaining reference uplink path loss and reference downlink path loss of a plurality of reference access network devices.

The reference access network device may be an access network device corresponding to a neighboring cell of the serving cell, or may not be an access network device corresponding to a neighboring cell, which is not limited in this disclosure.

In the embodiment of the present disclosure, the network management device or the OMC may acquire the uplink path loss and the downlink path loss of each cell or each access network device, so in the present disclosure, the network management device or the OMC may acquire the reference uplink path loss and the reference downlink path loss corresponding to the multiple reference access network devices.

Step 302, determining, for any reference access network device, a second difference between the corresponding reference uplink path loss and the reference downlink path loss.

In the embodiment of the disclosure, for any one reference access network device, a second difference (such as a difference value, an absolute value of the difference value, etc.) between the reference uplink path loss and the reference downlink path loss of the reference access network device may be calculated.

Step 303, determining the downlink beam gain of the access network device according to the second differences of the plurality of reference access network devices.

In the embodiment of the disclosure, the downlink beam gain of the access network device may be determined according to the second differences of the multiple reference access network devices.

As an example, the average of the second differences of the plurality of reference access network devices may be taken as the downlink beam gain of the access network device.

As another example, the minimum, maximum, or median of the second differences of the plurality of reference access network devices may be taken as the downstream beam gain of the access network device.

Step 304, obtaining an uplink path loss and a downlink path loss of the access network device, and determining a first difference between the uplink path loss and the downlink path loss.

Step 305, determining whether the coverage performance of the downlink beam in the serving cell corresponding to the access network device meets the set requirement according to the first difference and the downlink beam gain.

The explanation of steps 304 to 305 may be referred to the relevant descriptions in any embodiment of the disclosure, and are not repeated here.

The method for determining the coverage performance of the downlink beam can effectively determine the gain of the downlink beam of the access network equipment according to the difference between the reference uplink beams and the reference downlink beams of the plurality of reference access network equipment.

In order to clearly illustrate how the downlink loss of the access network device is determined in any embodiment of the present disclosure, the present disclosure further provides a method for determining the coverage performance of the downlink beam.

Fig. 4 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 4, the method for determining the coverage performance of the downlink beam may include the following steps:

step 401, obtaining downlink beam gain and uplink path loss of access network equipment.

The explanation of step 401 may be referred to the relevant description in any embodiment of the disclosure, and will not be repeated here.

Step 402, obtaining a first sending power of SSB in a serving cell corresponding to an access network device.

In the embodiments of the present disclosure, the first transmission power of the SSB may be a configuration value of the serving cell, which is a known parameter value for the access network device.

Step 403, obtaining a first RSRP sent by a terminal device in a serving cell; the first RSRP is obtained by measuring a downlink reference signal in a serving cell by a terminal device, and the terminal device is located in a coverage area of the SSB.

The downlink reference signal may include: CS-RS (Cell-SPECIFIC REFERENCE SIGNAL ), MBSFN-RS (Multicast Broadcast Single Frequency Network-REFERENCE SIGNAL, multicast broadcast single frequency network reference signal), US-RS (UE SPECIFIC REFERENCE SIGNAL, UE-specific reference signal), PRS (Positioning reference signal), CSI-RS (CHANNEL STATE Information-REFERENCE SIGNAL, channel state Information reference signal).

In the embodiment of the present disclosure, a terminal device located in a coverage area of an SSB in a serving cell may measure a downlink reference signal in the serving cell to obtain a first RSRP.

In the embodiment of the present disclosure, a first RSRP sent by a terminal device in a serving cell may be obtained.

As an example, when the execution body of the embodiment of the present disclosure is an access network device, the terminal device may directly send the first RSRP to the access network device, or the terminal device may also send the first RSRP to the access network device through the relay device.

As another example, when the execution body of the embodiment of the present disclosure is an OMC, the terminal device may send the first RSRP to the OMC through the access network device.

It should be noted that, the present disclosure does not limit the acquisition manner of the first RSRP.

As a possible implementation manner, the access network device may configure the terminal device to perform RSRP measurement of the downlink beam of the SSB, for example, the access network device may configure L1-RSRP reporting for the terminal device, and the access network device may obtain the first RSRP from the reporting information of the terminal device. Wherein L1 refers to Layer1 (physical Layer-Layer 1).

As another possible implementation, the first RSRP may also be obtained through the HL (HIGH LAYER, higher layer) measurement report measurement report. Because the statistics information is described above, the access network device does not need to configure measurement reporting for the terminal device additionally, and the measurement result of the SSB in the reporting of the existing serving cell SEVERING CELL is multiplexed.

As an example, RSRP in signaling reported by the SSB RSRP in measurement report may be subtracted 158 (a protocol assignment) to obtain the first RSRP obtained by the terminal device performing the SSB measurement.

Step 404, determining a downlink loss of the access network device according to the first transmission power and the first RSRP.

In the embodiment of the disclosure, the downlink loss of the access network device may be determined according to the first transmission power of the SSB and the first RSRP of the terminal device.

As an example, the downlink loss=first transmission power of SSB-first RSRP of the terminal device.

Step 405, determining a first difference between the uplink and downlink losses.

Step 406, determining whether the coverage performance of the downlink beam in the serving cell corresponding to the access network device meets the set requirement according to the first difference and the downlink beam gain.

The explanation of steps 405 to 406 may be referred to the relevant descriptions in any embodiment of the disclosure, and are not repeated here.

The method for determining the coverage performance of the downlink beam can effectively determine the downlink path loss of the access network equipment according to the RSRP and the SSB transmitting power measured by the terminal equipment in the coverage area of the SSB.

In order to clearly illustrate how to determine uplink loss of access network equipment in any embodiment of the present disclosure, the present disclosure further proposes a method for determining downlink beam coverage performance.

Fig. 5 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 5, the method for determining the coverage performance of the downlink beam may include the following steps:

Step 501, obtaining downlink beam gain and downlink path loss of access network equipment.

The explanation of step 501 may be referred to the relevant description in any embodiment of the disclosure, and will not be repeated here.

Step 502, obtaining a second transmission power of a single RB (Resource Block) transmitted by the terminal device.

In the embodiment of the present disclosure, the transmission power of the terminal device for transmitting a single RB may be acquired, which is denoted as the second transmission power in the present disclosure.

In a possible implementation manner of the embodiments of the present disclosure, the second transmission power of the terminal device for transmitting a single RB may be calculated by:

1) And obtaining the maximum sending power of the terminal equipment for sending the uplink transmission to the access network equipment.

The uplink transmission may be signaling, data, signaling/data hybrid transmission. Uplink transmissions include, but are not limited to, transmissions of PUCCH (Physical Uplink Control Channel ), PUSCH (Physical Uplink SHARD CHANNEL, physical Uplink shared channel), and the like.

2) And acquiring an uplink PHR (Power Headroom Report, a power headroom report) of the terminal equipment.

In the embodiment of the present disclosure, the second transmission power of the terminal device to transmit a single RB may be determined according to the maximum transmission power of the terminal device, the uplink PHR, and the first number.

As an example, the mark maximum transmission POWER is max_power, and the second transmission POWER may be: max_power-PHR-10 log10 (first number of PRBs).

Step 503, obtaining a second RSRP obtained by the access network device by measuring the uplink reference signal in the serving cell.

Wherein, the uplink reference signal may include: DMRS (Demodulation REFERENCE SIGNAL ), SRS (Sounding REFERENCE SIGNAL, sounding reference signal).

And step 504, determining the uplink path loss of the access network equipment according to the second RSRP and the second transmission power.

In the embodiment of the present disclosure, the uplink loss of the access network device may be determined according to the second RSRP and the second transmission power.

As an example, uplink loss = second transmit power-second RSRP.

The explanation of steps 505 to 506 may be referred to the relevant descriptions in any embodiment of the present disclosure, and will not be repeated here.

The method for determining the coverage performance of the downlink beam can effectively determine the uplink path loss of the access network equipment according to the transmission power of the terminal equipment for transmitting the single RB and the RSRP measured by the access network equipment.

In order to clearly explain how to determine whether the coverage performance of the downlink beam in the serving cell meets the set requirement in any of the above embodiments, the present disclosure further provides a method for determining the coverage performance of the downlink beam.

Fig. 6 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 6, the method for determining the coverage performance of the downlink beam may include the following steps:

step 601, obtaining a downlink beam gain of an access network device.

The explanation of step 601 may be referred to the related description in any embodiment of the present disclosure, and will not be repeated herein.

Step 602, obtaining an uplink path loss and a downlink path loss of an access network device, and determining a first difference between the uplink path loss and the downlink path loss, where the number of terminal devices in a serving cell corresponding to the access network device is multiple, and the first difference is multiple.

In the embodiment of the present disclosure, a downlink path loss may be calculated according to a first RSRP sent by each terminal device in a serving cell, and an uplink path loss may be calculated according to a second transmission power of the terminal device for transmitting a single RB, and a difference between the uplink path loss and the downlink path loss may be calculated to obtain a first difference.

Therefore, when the number of the terminal devices in the service cell corresponding to the access network device is multiple, the first differences can be calculated through the mode.

Step 603, determining that the first difference is greater than a second amount of downstream beam gain.

In the embodiment of the present disclosure, each first difference may be compared with the downstream beam gain to determine a first difference greater than the downstream beam gain, and the number of the first differences greater than the downstream beam gain is counted, which is denoted as a second number in the present disclosure.

Step 604, a third number of terminal devices is determined.

In the embodiment of the present disclosure, the number of the terminal devices may be counted, and is denoted as a third number in the present disclosure.

Step 605, determining whether the coverage performance of the downlink beam in the serving cell meets the set requirement according to the ratio of the second number to the third number.

In the embodiment of the present disclosure, it may be determined whether the coverage performance of the downlink beam in the serving cell meets the set requirement according to the ratio of the second number to the third number (i.e., the second number/the third number).

As an example, the ratio of the second number to the third number may be compared with a set probability threshold, when the ratio is greater than the set probability threshold, it may be determined that the coverage performance of the downlink beam in the serving cell meets the set requirement, and when the ratio is less than or equal to the set probability threshold, it may be determined that the coverage performance of the downlink beam in the serving cell does not meet the set requirement.

The set probability threshold is a preset probability threshold, for example, the set probability threshold may be 70%, 75%, or the like.

The coverage performance of the downlink beam may be that of a certain SSB in the serving cell, or may be that of the downlink beam of the entire serving cell.

As a possible implementation manner, when the plurality of terminal devices are located in the coverage area of one SSB, the coverage performance of the downlink beam calculated by the step may be the coverage performance of the downlink beam of the SSB.

As an example, the locations of the plurality of terminal devices may be obtained, and when the locations of the plurality of terminal devices are located in the coverage area of the same SSB, it may be determined whether the ratio of the second number to the third number is greater than a first probability threshold, where the first probability threshold is a preset threshold, for example, the first probability threshold may be 75%, 80%, or the like.

Under the condition that the ratio is larger than the first probability threshold, it can be determined that the coverage performance of the downlink beam of the same SSB in the serving cell meets the set requirement, and under the condition that the ratio is smaller than or equal to the first probability threshold, it can be determined that the coverage performance of the downlink beam of the same SSB in the serving cell does not meet the set requirement.

As a possible implementation manner, when the plurality of terminal devices are located in coverage areas of the plurality of SSBs, the coverage performance of the downlink beam calculated by the step may be the coverage performance of the downlink beam of the entire serving cell.

As an example, the locations of the plurality of terminal devices may be obtained, and when the locations of the plurality of terminal devices are located in coverage areas of different SSBs, it may be determined whether a ratio of the second number to the third number is greater than a second probability threshold, where the second probability threshold is also a preset threshold, and the second probability threshold is smaller than the first probability threshold, for example, the second probability threshold may be 65%, 70%, or the like.

Under the condition that the ratio is larger than the second probability threshold, it can be determined that the coverage performance of the downlink beam of the different SSBs in the serving cell meets the set requirement, and under the condition that the ratio is smaller than or equal to the second probability threshold, it can be determined that the coverage performance of the downlink beam of the different SSBs in the serving cell does not meet the set requirement.

The method for determining the coverage performance of the downlink beam in the embodiment of the disclosure can effectively determine the coverage performance of the downlink beam in the service cell according to the path loss difference distribution of the terminal equipment in the service cell, or can effectively determine the coverage performance of the downlink beam of the SSB according to the path loss difference distribution of the terminal equipment in the SSB coverage area.

In a possible implementation manner of the embodiment of the present disclosure, in a case where the coverage performance of the downlink beam in the serving cell does not meet the set requirement, the downlink beam in the serving cell may also be adjusted. The above process will be described in detail with reference to fig. 7.

Fig. 7 is a flow chart illustrating another method for determining coverage performance of a downlink beam according to an embodiment of the present disclosure.

As shown in fig. 7, on the basis of any one of the above embodiments, the method for determining the coverage performance of the downlink beam may further include the following steps:

In step 701, in case the coverage performance of the downlink beam in the serving cell does not meet the set requirement, a fourth number of terminal devices in the coverage area of at least one SSB in the serving cell is obtained.

In the embodiment of the present disclosure, in a case where the coverage performance of the downlink beam in the serving cell does not meet the set requirement, the fourth number of terminal devices in the coverage area of at least one SSB in the serving cell may be acquired.

As an example, the SSBs where the terminal devices are located may be obtained according to measurement report of HL, so that for each SSB, the number of terminal devices located in the coverage area of the corresponding SSB may be counted.

As another example, the SSBs in which the terminal device is located may be obtained according to RSRP reporting of the terminal device, so that for each SSB, the number of terminal devices located in the coverage area of the corresponding SSB may be counted.

Wherein when the number of SSBs is plural, a fourth number of terminal devices within the coverage area of each SSB may be acquired.

Step 702, obtaining an AOA (horizontal angle Of Arrival) distribution and an EOD (Elevation Of Departure, vertical angle Of Arrival) distribution Of terminal devices within a coverage area Of at least one SSB.

The AOA and EOD may be obtained by calculation based on an uplink SRS (Sounding REFERENCE SIGNAL ).

In the embodiment of the present disclosure, for any one SSB of the at least one SSB, an AOA distribution and an EOD distribution of a terminal device in a coverage area of the SSB may be acquired.

Step 703, adjusting the downstream beam of the at least one SSB according to at least one of the fourth number, the AOA distribution and the EOD distribution.

In the embodiment of the disclosure, for any one SSB, the downlink beam of the SSB may be adjusted according to the fourth number of terminal devices, the AOA distribution, and the EOD distribution in the coverage area of the SSB. For example, the downlink beam range, the horizontal central angle of the downlink beam, the digital downtilt angle, the beam distribution of each layer of beam, and the like can be adjusted, so that the coverage performance of the downlink beam of the adjusted SSB meets the set requirement.

As an example, two-dimensional distribution (AOA distribution, EOD distribution) of terminal devices in the coverage area of each SSB may be counted, if there are no terminal devices in the coverage area of a certain SSB or the number of terminal devices (i.e. the fourth number) is small, the beam plan corresponding to the SSB is not suitable, and the downlink beam of the SSB may be optimized, for example, an area where there is a terminal device but the beam coverage of the SSB is not good may be adjusted, and after adjustment, the distribution of terminal devices is concentrated in the downlink beam range covered by the SSB.

As another example, assume that the downlink horizontal beam of the access network device is ±45 degrees, and the downtilt angle is 3-9 degrees; if the AOA distribution of the terminal equipment is concentrated in the range of [ -60,50], the horizontal center beam of the terminal equipment needs to be adjusted to-5 degrees, and the horizontal beam coverage needs to be adjusted to + -55 degrees.

As yet another example, assume that the downlink beam of the access network device is ±45 degrees, and the downtilt angle is 3-9 degrees; if the EOD distribution of the terminal device is concentrated in the range of [1,7], the horizontal center beam of the terminal device needs to be adjusted to 3 degrees.

As a possible implementation manner, in the case that the coverage performance of the downlink beam of a certain SSB in the serving cell does not meet the set requirement, the fifth number of terminal devices in the coverage area of the SSB may be obtained, and the AOA distribution and the EOD distribution of the terminal devices in the coverage area of the SSB may be obtained, so that the downlink beam of the SSB may be adjusted according to the fifth number of terminal devices in the coverage area of the SSB, the AOA distribution and the EOD distribution, so that the coverage performance of the downlink beam of the adjusted SSB meets the set requirement.

The method for determining the coverage performance of the downlink beam in the embodiment of the disclosure can realize the adjustment of the downlink beam of the SSB according to the number of terminal equipment, AOA distribution and EOD distribution in the coverage area of the SSB so as to improve the coverage performance of the downlink beam of the SSB.

Through the embodiments, the coverage performance of the downlink beam of the corresponding cell of each access network device can be obtained, so that cells with the coverage performance not reaching the standard can be screened according to the coverage performance of the downlink beam of each cell, and the adjustment thought or adjustment strategy corresponding to the cells with the coverage performance not reaching the standard can be determined, thereby having extremely important effect on intelligent network operation and maintenance.

Because the TDD (Time Division Duplexing) system is a typical diversity system, uplink and downlink path losses are also different, the present disclosure can obtain coverage performance of downlink beams of a cell by using the characteristic of the difference between the uplink and downlink path losses of the system.

Specifically, since the uplink reception of the access network device is omni-directional reception, the uplink path loss is irrelevant to the downlink beam distribution of the access network device, and thus the uplink path loss can be taken as an expected output. And the downlink loss of the access network equipment has a great relation with the beam planning, and the downlink loss of the access network equipment is minimized when the beam planning is optimal. In addition, the uplink path loss and the downlink path loss of the access network device are related to factors such as public parameters of the access network device (such as height of the access network device, antenna array gain and the like), environment distribution of a cell and the like, and the factors are embodied in the uplink path loss and the downlink path loss, are common influence factors, and can be subtracted from each other to remove the common influence factors. Therefore, the coverage performance of the downlink beam of the cell SSB can be measured by using the difference between the uplink path loss and the downlink path loss of the access network device.

The specific process flow may be as shown in fig. 8, and may include the following steps:

in step 81, a theoretical beam gain (denoted as reference beam gain in the present disclosure) and an actual beam gain (denoted as downlink beam gain in the present disclosure) are determined according to the antenna configuration information of the access network device.

For example, the antenna of the access network device is configured as [ M, N, P ] = [4,8,2], where M is the number of rows of the antenna array, N is the number of columns of the antenna array, and P is the number of polarization directions, and the theoretical beam gain=10log ₁₀ (m×n), and the actual beam gain bf_gain may perform delta (back-off beam gain) back-off based on the theoretical beam gain as the expected value. For example, the default delta may be 3db, bf_gain=10×log ₁₀ (m×n) -delta.

As an example, assume that the number of antennas of the corresponding cell of the access network device is 64, the antenna configuration is 4 (row, vertical element number) ×8 (column, horizontal element number) ×2 (dual polarization), the horizontal pitch of the antennas is 0.5 wavelength, the vertical pitch is 1.9 wavelength, the horizontal bandwidth of a single element is 120 degrees, and the vertical bandwidth is 25 degrees; the horizontal resolution of the antenna array is 15 °, the vertical resolution is 6 °, and then the theoretical beam gain=15 dB.

1) Bf_gain=10×log ₁₀ (8*4) -delta=15-3=12 dB if the horizontal beam width of SSB in the serving cell is comparable to the horizontal resolution and/or the vertical beam width of SSB is comparable to the vertical resolution.

2) If the horizontal beam width of the SSB is doubled on the basis of the horizontal resolution and/or the vertical beam width of the SSB is doubled on the basis of the vertical resolution, bf_gain may be reduced by 3dB on the basis of 1), such as the beam width of the SSB is adjusted to 30 °, bf_gain is 9dB.

3) If there are multiple SSBs in the serving cell, the bf_gain of the serving cell may be the gain combination of bf_gain of each SSB, e.g., if bf_gain of different SSB beams is equivalent, bf_gain of the entire serving cell may be the average of bf_gain of different SSB beams.

Step 82, obtaining downlink loss of the access network device. Wherein downlink loss=first transmission power of SSB-first RSRP of terminal device.

Wherein the first transmit power of the SSB may be a configuration value of the serving cell, the access network device is known.

The method for obtaining the first RSRP of the terminal device is not limited, for example, the method may be obtained by configuring the terminal device according to the access network device to perform RSRP measurement of the SSB (for example, the access network device reports to the terminal device by configuring L1-RSRP, the access network device may obtain the first RSRP of the terminal device in the report information of the terminal device), or may also obtain the first RSRP through measurement report of HL (because the first RSRP is statistical information, it is only necessary to multiplex the measurement result of the SSB in the report of the existing SEVERING CELL without additionally configuring measurement report to the terminal device).

Step 83, obtaining the uplink loss of the access network device.

The channel used for the Uplink loss measurement is not limited, and an SRS channel or a PUSCH (Physical Uplink SHARED CHANNEL) channel may be used, and the RSRP of the Uplink single RB single antenna of the terminal device may be calculated, where the PUSCH channel may be used when the Uplink traffic of the terminal device is relatively large, and the SRS channel may be used when the Uplink traffic of the terminal device is relatively small. In order to avoid the influence of abnormal data on the measurement result, the data of correct PUSCH decoding and SRS activation can be used to determine the uplink loss.

The access network device may calculate a transmission POWER of a single RB of the terminal device (denoted as a second transmission POWER in this disclosure) =max_power-PHR-10×log ₁₀ (PRB number) according to the maximum transmission POWER max_power and the uplink PHR of the terminal device.

Uplink loss = second transmit power of terminal device-second RSRP received by the access network device; the second RSRP received by the access network device is an existing measurement quantity of the access network device, and the second RSRP can be obtained by using an existing measurement algorithm without additional increase.

Step 84, the distribution of the path loss difference pathloss _dis is counted. Wherein pathloss _dis=uplink loss-downlink loss.

The probability that the serving cell pathloss dis is greater than bf_gain (noted in this disclosure as the ratio of the second number to the third number) is counted, the greater the probability the better the coverage performance of the serving cell. A probability threshold cdf_vth may be set, and if the probability pathloss _dis > bf_gain is less than or equal to cdf_vth, it is determined that the coverage performance of the serving cell is poor, and the serving cell is abnormal. For example, the default value of cdf_vth may be set to 70%, and the probability threshold may be adjusted according to the actual use requirement.

The statistics of the path loss difference distribution may be for all terminal devices in the serving cell, or may be for terminal devices in the coverage area of each SSB index (one index corresponds to one SSB). If all terminal devices in the serving cell are aimed at, the coverage performance of the whole serving cell can be properly relaxed, and if the terminal devices in the ssb index coverage area are aimed at, the expected bf_gain can be finer, the cdf_vth can be set more strictly, and the statistical distribution of the cell level can be adopted to identify whether the cell is abnormal or not in the initial optimization.

In step 85, it is determined whether the downlink beam in the serving cell needs to be optimized (i.e., whether the serving cell is abnormal) according to the probability pathloss _dis > bf_gain, for example, when the probability pathloss _dis > bf_gain is less than or equal to cdf_vth, it is determined that the serving cell is abnormal, and when the probability pathloss _dis > bf_gain is greater than cdf_vth, it is determined that the serving cell is normal without optimization.

In step 86, in case optimization is required, the ssb index, AOA distribution and EOD distribution of the terminal device in the serving cell may be further analyzed. The AOA and EOD may be obtained by calculation based on the uplink SRS.

In step 87, according to the ssb index, the AOA distribution and the EOD distribution, an adjustment policy is output, for example, the adjustment policy may be used to instruct adjustment of the horizontal central angle, the digital downtilt angle, etc. of the downlink beam in the serving cell, and even the beam distribution of each layer of beam, etc.

The method for obtaining the ssb index is not limited, and may be obtained according to measurement report of HL, or may also be obtained according to RSRP report of the terminal device.

It should be noted that, if SSB beam planning is appropriate, most terminal devices should be within 3dB of the access network device planning beam; the downlink beam range of the whole coverage of the access network device and the coverage of each SSB can be known according to the beam planning of the access network device. According to the current cell beam configuration corresponding to the serving cell, a coverage delta_gain dB (delta_gain is configurable, default value is 3, the delta_gain dB coverage is an offset relative to the maximum beam gain, delta_gain dB coverage is a region with gain greater than max_gain (theoretical beam gain) -delta_gain) can be drawn, similar to drawing a coverage circle, each terminal device is a scattered point in the coverage circle, the schematic diagram is shown in fig. 9, wherein the region 91 is the current coverage circle of the cell, each point is a terminal device), and the optimization is achieved through terminal device distribution and iteration of the coverage circle.

The beam planning of the serving cell can be adjusted through the adjustment strategy of the step 86, the steps are repeated, the adjustment strategy is obtained according to pathloss dis distribution before and after adjustment, the beam planning of the serving cell is adjusted, and the coverage performance of the downlink beam in the serving cell can be improved through multiple iterations.

In summary, the coverage performance of the downlink beam of the serving cell can be obtained through the uplink and downlink path loss difference distribution of the access network equipment by utilizing the characteristic of different path losses, and the abnormal cell is output according to the path loss difference distribution; for an abnormal cell, the SSB coverage beam of the cell can be checked by combining with the AOA, EOD and SSB index information of the terminal equipment, and an adjustment strategy is given; and adjusting the coverage beam of the cell according to the adjustment strategy, and counting the path loss difference distribution of the cell again after adjustment, and iteratively obtaining the better beam coverage of the cell.

In the embodiment of the disclosure, the coverage performance of the downlink beam of each cell or SSB can be obtained, and the access network equipment or cells and possible adjustment strategies which do not reach the standard can be rapidly screened out, so that the method has at least the following advantages:

Firstly, by utilizing the different path loss characteristics of TDD, index data (uplink and downlink path loss difference distribution) for indicating the coverage condition of downlink SSB of a cell can be automatically output, and the problem that the coverage performance of downlink beams is difficult to identify because the downlink path loss in different frequency bands and different scenes is not expected (the test result depends on the problem of testers or analysts) can be solved.

Secondly, the coverage performance of the downlink SSB is obtained by adopting the existing measured value of the network side, and the extra work and data transmission of access network equipment are not added; the coverage performance not only can be used for comparing coverage indexes under different configurations, but also can be used for rapidly identifying access network equipment with relatively poor coverage performance, and can be further used for network coverage optimization iteration.

Thirdly, according to the operation, the test result can be automatically output at the access network equipment side according to the existing measurement data, manual intervention is not needed, the labor cost can be saved, the application range is wider, the operation and maintenance efficiency is improved, and the cost is reduced.

Fourth, although the above description is described according to the access network device side, the whole operation is not limited to be completed at the access network device side, and measurement data can be reported to the OMC through the access network device, and the OMC can complete the operation, so that the optimization evolution to the intelligent network can be facilitated.

Fifth, the above scheme can be applied not only to a 5G system but also to an LTE (Long Term Evolution ) system, with the following differences: when applied to LTE systems, the theoretical beam gain (i.e., reference beam gain) needs to be adjusted to the theoretical wide beam gain of CRS (CELL REFERENCE SINGAL, cell-level reference signal). Because networking of a plurality of existing systems is multimode or common-mode networking, 4G is changed when scene distribution of 5G equipment is adjusted, and the scheme can be used for identifying CRS coverage performance and network optimization.

In order to implement the above embodiment, the present disclosure further provides an access network device.
