However, the number and distribution of terminal devices in different cells are different, and how to adjust the SRS transmission mode for specific scenes of different cells, so as to improve the accuracy of channel estimation performed by the network device according to the SRS is a problem to be solved urgently.

Detailed Description

The embodiments of the present application will be described in detail below with reference to the drawings attached hereto.

The embodiment of the present application can be applied to a mobile communication system that performs communication in a TDD manner, for example: a New Radio (NR) system, a Long Term Evolution (LTE) -TDD system, an advanced long term evolution (LTE-a) system, an evolved Long Term Evolution (LTE) system, a future communication system, and other communication systems, and in particular, is not limited herein.

In the embodiment of the present application, the terminal device is a device having a wireless transceiving function or a chip that can be disposed in the device. A terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a user agent, or a user equipment, among others. In practical applications, the terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios.

In this embodiment, the network device may be a wireless access device in various standards, for example, a next Generation base station (gNB) in an NR system, and may also be a network node forming a gNB, such as a DU of the gNB in a centralized-distributed (CU-DU) architecture; may be an evolved Node B (eNB), a Radio Network Controller (RNC) or a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B or home Node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission point (TRP or transmission point, TP), etc., which are not illustrated herein one by one.

For the convenience of understanding the embodiments of the present application, a communication system applicable to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1 as an example. Fig. 1 shows a schematic diagram of a communication system suitable for the communication method of the embodiment of the present application. As shown in fig. 1, the communication system includes a network device 101 and a network device 102. Network device 101 manages cell 1 and cell 2, e.g., network device 101 may communicate with terminal devices located within the coverage of cell 1 and cell 2; network device 102 manages cell 3. Each of cell 1, cell 2, and cell 3 includes at least one terminal device.

For example, most terminal devices in cell 1 are mainly in a relatively static state, and are located at the edge of cell 1; most terminal devices in the cell 2 are mainly in a relatively static state and are located near the center of the cell 2; most terminal equipments in the cell 3 are mainly in a mobile state.

In the prior art, regardless of the state of the terminal device in the cell, all the terminal devices in the cell 1, the cell 2, and the cell 3 all use the same transmission method to transmit the uplink reference signal. The transmission mode of the uplink reference signal includes a transmission period of the uplink reference signal, a transmission power of the uplink reference signal, and a transmission bandwidth of the uplink reference signal, which may be specifically referred to as shown in fig. 2. The transmission period is a time interval between two times of uplink reference signal transmission, and the unit can be millisecond (ms); the transmission power is the power used for transmitting the uplink reference signal each time, and the unit can be decibel-milliwatt (dBm); the transmission bandwidth is a bandwidth occupied by the uplink reference signal, and may be in megahertz (MHz), and the uplink reference signal may be transmitted over a full frequency band or may be transmitted over a partial frequency band.

For example, in the cell 1, if the terminal device uses the existing full frequency band to transmit the uplink reference signal, the power of the uplink reference signal on a single Resource Element (RE) is limited, which causes the signal quality to be degraded, and the channel estimation result obtained by the network device is obviously inaccurate. The channel corresponding to the terminal device in the cell 3 belongs to a time-varying channel, and for the time-varying channel, the transmission period of the uplink reference signal needs to be shortened as much as possible, so that the network device can complete channel estimation more quickly. Therefore, if the transmission period of the row reference signal in the cell 3 is too large, it will also result in that an accurate channel estimation result cannot be obtained.

Therefore, the embodiment of the present application provides a method, which can determine different transmission modes for different cells according to different scenarios of the cells, thereby improving the accuracy of channel estimation performed by a network device according to an uplink reference signal.

In addition, in the embodiments of the present application, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term using examples is intended to present concepts in a concrete fashion.

Before the method provided by the present application is executed, uplink reference signals sent by different terminal devices may be measured in a cell, or Measurement Reports (MR) reported by different terminal devices may be collected, so as to obtain a test data set of the cell. The uplink reference signal may be an SRS, or may also be another type of reference signal, which is not limited in this embodiment. The test data set may be a pull test (DT) data set or may be a measurement report data set. The network device may measure, in a cell, an uplink reference signal sent by a terminal device used by a user, thereby obtaining a test data set. The terminal devices may be terminal devices used by actual users, or terminal devices used by users simulated by testers, which is not limited in this embodiment of the present application.

In the embodiment of the application, after the network device acquires the test data set, the transmission mode of the uplink reference signal in the cell of the network device can be determined according to the test data set. Or, referring to fig. 3, the network device transmits the test data set to the network management device, and the network management device determines the transmission mode of the uplink reference signal. And after determining the transmission mode of the uplink reference signal, the network management equipment transmits the uplink reference signal to the network equipment. It should be noted that the network management device may be any computer device, and the embodiment of the present application does not limit the specific type of the network management device.

In this embodiment, the test data set may include test data of a plurality of cells, where each test data includes data corresponding to various parameters, and may include, but is not limited to, the following parameters:

data acquisition time; longitude and latitude coordinates of the network device; sending longitude and latitude coordinates of terminal equipment of an uplink reference signal; physical-layer Cell identity (PCI) of a Cell; reference Signal Receiving Power (RSRP) of the uplink reference signal; frequency points of the cell; a downlink single antenna signal to interference plus noise ratio (SINR); uplink reference signal transmission power; rank (rank) of the downlink; path loss; a Channel Quality Indicator (CQI); modulation and Coding Scheme (MCS); and (4) downlink MCS.

The above are only examples, and other parameters may also be included in the test data set, which are not illustrated herein one by one.

For example, the test data set for a cell may be as shown in table 1.

In table 1, the test data set includes a plurality of test data, each row represents one test data, and one test data includes data corresponding to a plurality of parameters. It should be noted that table 1 is only an example, and each test data in table 1 may further include data corresponding to other parameters, which are not illustrated herein one by one.

With reference to fig. 4, a flowchart of a method for determining an uplink reference signal transmission mode according to an embodiment of the present application is shown. The execution subject in the flow shown in fig. 4 may be a network device, or may also be other types of computer devices, such as a network management device. When the execution subject is the network management device, the network management device can send the determined transmission mode to the network device. As shown in fig. 4, the method includes:

step 401: the method comprises the steps of obtaining a test data set of a cell, and determining a wireless channel state data set of the cell from the test data set.

In the embodiment of the application, the test data set comprises more parameters, and only part of the parameters are needed when the transmission mode of the uplink reference signal is determined. In this embodiment, a wireless channel state data set may be determined from the test data set, and the wireless channel state data set may be used to determine a transmission mode of the uplink reference signal. The wireless channel state data set includes a plurality of wireless channel state data, and the data included in the wireless channel state data set is data corresponding to a part of parameters in the test data set, that is, the wireless channel state data set may be a subset of the test data set.

For example, in the embodiment of the present application, the wireless channel state data set may include, but is not limited to, data corresponding to one or more of the following parameters:

the channel loss corresponding to the cell, the uplink reference signal transmitting power corresponding to the cell, the downlink single antenna SINR corresponding to the cell, and the downlink average rank corresponding to the cell.

The above is only an example, and the wireless channel state data set may further include data corresponding to other parameters, which are not illustrated herein one by one.

In the embodiment of the present application, a transmission mode of an uplink reference signal currently configured by a cell may also be obtained. For example, the transmission mode of the uplink reference signal currently configured by the cell may be determined by the configuration data of the cell. The configuration data of the cell includes, but is not limited to, information such as a transmission mode of an uplink reference signal currently configured in the cell, a cell identifier, and an identifier of a network device to which the cell belongs.

In the embodiment of the application, the PCI and the frequency point of the cell corresponding to the test data set can be determined through the test data set, the cell identifier of the cell corresponding to the configuration data can be determined through the configuration data, and therefore the test data set and the configuration data corresponding to the same cell can be associated. Specifically, the test data set of the cell may be associated with the configuration data by the working parameters of the cell. It should be noted that the engineering parameters are abbreviated as engineering parameters, and the engineering parameters include parameter information of the cell, and the parameter information includes, but is not limited to, information such as PCI, longitude and latitude coordinates, frequency points, and cell identifiers of the cell.

Referring to fig. 5, the PCI, the frequency point, and the cell identifier of the cell may be determined through the working parameters of the cell. Therefore, a test data set comprising the PCI and the frequency point in the work parameter of the cell can be determined according to the work parameter of the cell; determining configuration data comprising a cell identifier in the work parameters of the cell from a plurality of configuration data according to the work parameters of the cell; the determined test data set may thus be associated with the configuration data.

Step 402: and determining the transmission mode of the uplink reference signal in the cell according to the wireless channel state data set.

The transmission mode of the uplink reference signal comprises one or more of the following modes: the transmission period, the transmission power or the transmission bandwidth of the uplink reference signal.

In the above process, the DT data set is obtained by measuring the uplink reference signal in the cell to obtain the test data set of the cell, or the test data set of the cell is obtained based on the MR data sets reported by different terminal devices, and the transmission mode of the uplink reference signal corresponding to the cell can be determined according to the wireless channel state data set in the test data set of the cell. By the method, the transmission mode of the uplink reference signal of the cell is configured according to the wireless channel state data set of the cell, so that the network equipment can accurately estimate the channel according to the uplink reference signal.

In this embodiment of the present application, in a first possible implementation manner, a transmission manner of an uplink reference signal may be determined by:

step one, grid-level wireless channel state data of the at least one grid area is determined according to the wireless channel state data set of the cell.

The grid-level wireless channel state data comprises data corresponding to one or more of the following parameters: path loss corresponding to the grid area; transmitting power of an uplink reference signal corresponding to the grid area; a downlink single antenna SINR corresponding to the grid area; and the downlink average rank corresponding to the grid region.

In this embodiment of the present application, a cell may be divided into at least one grid region, and the size of each grid region is determined according to an actual situation, which is not limited in this embodiment of the present application.

When a cell includes a grid region, the whole cell can be regarded as a grid region; when a plurality of grid regions are included in a cell, the sum of the areas of the grid regions included in the cell may be greater than or equal to the area of the entire cell.

For example, as shown in fig. 6, the cell in fig. 6 may be divided into 16 grid regions, each grid region is not overlapped with another grid region, and the sum of the areas of the 16 grid regions is equal to the area of the cell. Fig. 6 is an example, and the number of grid regions and the size of the grid regions included in one cell may also be other cases, which are not described herein again.

In this embodiment, the wireless channel state data set includes a plurality of wireless channel state data, and for this purpose, the wireless channel state data corresponding to the same grid region in the wireless channel state data set may be regarded as a group of wireless channel state data. The wireless channel state data corresponding to the same grid area refers to data acquired in the same grid area, for example, when the wireless channel state data in the wireless channel state data set is determined by a measurement report reported by a terminal device, the measurement report may include longitude and latitude coordinates, so that the wireless channel state data acquired by the measurement report in the same grid area may be used as a group of wireless channel state data according to the longitude and latitude coordinates.

After determining a set of wireless channel state data corresponding to a grid region, grid-level wireless channel state data corresponding to the grid region may be determined according to the set of wireless channel state data.

For example, the mean value of a set of wireless channel state data corresponding to a grid region may be used as the grid-level wireless channel state data corresponding to the grid region.

For another example, the median of a group of wireless channel state data corresponding to a grid region may be used as the grid-level wireless channel state data corresponding to the grid region.

The above is only an example, and the trellis-level wireless channel status data may also be determined in other manners, which is not described herein again.

It should be noted that, in a group of wireless channel state data corresponding to a grid region, there may be abnormal wireless channel state data, for example, the path loss in the wireless channel state data is greater than a preset maximum value or less than a preset minimum value, and after the abnormal wireless channel state data is deleted, the grid-level wireless channel state data is determined. How to determine the abnormal wireless channel state data is determined according to the actual situation, and details are not described herein. If the wireless channel state data in a group of wireless channel state data corresponding to a grid region are all abnormal data, or the number of the wireless channel state data corresponding to a grid region is 0, the grid-level wireless channel state data of the grid region may not be determined any more, or the grid-level wireless channel state data of the grid region is determined to be equal to 0.

And secondly, determining a grid-level spectrum efficiency model of the at least one grid region according to the grid-level wireless channel state data of the at least one grid region.

The grid-level spectrum efficiency model is a model taking one or more of an emission period variable, an emission power variable and an emission bandwidth variable as an independent variable and is used for determining the spectrum efficiency of a downlink channel in a corresponding grid region.

It should be noted that the downlink channel may refer to a Physical Downlink Shared Channel (PDSCH), may also refer to a downlink shared transmission channel for carrying downlink shared transmission channels, may also refer to a downlink channel for carrying main user data, may also refer to a downlink signal based on beamforming of an uplink reference signal, and the like, and the embodiment of the present application is not limited thereto.

In an embodiment of the present application, for any one of the at least one grid region, for example, a first grid region, a grid-level spectral efficiency model of the first grid region may be determined according to one or more of the following: the downlink average rank in the trellis-level wireless channel state data corresponding to the first trellis region, and the SINR of the PDSCH corresponding to the first trellis region.

Further, the SINR of the PDSCH corresponding to the first grid region may be determined according to one or more of the following: the number of downlink transmission physical ports in the cell; a downlink single antenna signal to noise ratio SINR in the grid-level wireless channel state data corresponding to the first grid region; a channel estimation error corresponding to the first grid region; and transmitting power of a downlink channel single antenna single Resource Element (RE) in the cell.

For example, in conjunction with the foregoing description, a grid level spectral efficiency model Se of grid region j in cell i_i,jCan satisfy the following formula (1):

wherein N is_i,jIs a preset coefficient;

the SINR of the PDSCH corresponding to the grid region j in the cell i; rank_i,jAnd the average downlink rank in the state data of the grid-level wireless channel corresponding to the grid region j is obtained. The SINR of the PDSCH corresponding to the grid region j may satisfy the following formula (2):

wherein NT is_iThe number of downlink transmission physical ports in a cell i;

the downlink single antenna SINR in the grid level wireless channel state data corresponding to the grid region j in the cell i is obtained;

the channel estimation error for grid region j in cell i.

Channel estimation error for grid region j

The channel estimation error of the grid region j is a model with one or more of a transmission period variable, a transmission power variable and a transmission bandwidth variable as independent variables

May also be related to one or more of the following parameters: noise at the bottom of the uplink channel^u(ii) a Path loss corresponding to the grid area; uplink reference signal transmitting power currently configured for cell i

The cell i is currently configured with an uplink reference signal transmission period; the uplink reference signal transmitting bandwidth currently configured in a cell i; uplink reference signal transmitting power corresponding to grid region j in cell i

Single RE uplink reference signal transmitting power of terminal equipment corresponding to grid region j in cell i

Path loss from cell i to grid area j in a cell adjacent to cell i

Average moving Speed of terminal equipment in grid area j in cell i_i,j(ii) a Equivalent uplink reference signal length corresponding to grid region j in cell i

In the above formula, in the grid-level spectrum efficiency model of each grid region, the initial values of parameters other than the transmission period variable, the transmission power variable, and the transmission bandwidth variable may be determined according to the grid-level wireless channel state data of the grid region, the uplink reference signal transmission mode currently configured by the cell, and the like.

And step three, determining the transmitting mode of the uplink reference signal in the cell according to the grid-level spectrum efficiency model of the at least one grid region.

Specifically, at least one preconfigured transmission pattern is obtained, wherein each preconfigured transmission pattern in the at least one preconfigured transmission pattern includes one or more of the following: a period value corresponding to a transmission period variable in the grid-level spectral efficiency model; a power value corresponding to a transmission power variable in the grid-level spectrum efficiency model; and transmitting bandwidth values corresponding to the bandwidth variables in the grid-level spectral efficiency model.

The at least one preconfigured transmission manner may be configured by the network device, or may be determined by other manners, which is not limited in this embodiment of the present application.

For example, the at least one preconfigured transmission pattern may be as shown in table 2.

TABLE 2

After at least one pre-configured transmission mode is obtained, the 1 st pre-configured transmission mode to the H th pre-configured transmission mode can be selected in sequence, wherein H is the number of the pre-configured transmission modes.

Assuming that an mth preconfigured transmission means is currently selected from the at least one preconfigured transmission means; m is an integer greater than 0. And respectively taking the period value, the power value and the bandwidth value in the selected mth pre-configured transmission mode as the values of a transmission period variable, a transmission power variable and a transmission bandwidth variable in the grid-level spectrum efficiency model of each grid region.

For a first grid region in the cell, where the first grid region is any grid region in the cell, a grid-level spectral efficiency model of the first grid region may be initialized according to the wireless channel state data of the first grid region, that is, parameters in the grid-level spectral efficiency model of the first grid region are assigned.

For example, the initial value of the downlink average rank in the grid-level spectral efficiency model of the first grid region may be the downlink average rank in the grid-level wireless channel state data corresponding to the first grid region; the initial value of the downlink single antenna SINR in the grid-level spectral efficiency model of the first grid region may be the downlink single antenna SINR in the grid-level wireless channel state data corresponding to the first grid region; the initial value of the uplink reference signal transmission power in the grid-level spectrum efficiency model of the first grid region may be the uplink reference signal transmission power in the grid-level wireless channel state data corresponding to the first grid region, and the like. Other parameters in the grid-level spectral efficiency model of the first grid region may be initialized accordingly, and are not described herein again.

Through the above procedure, the spectral efficiency of the downlink channel of the first grid region may be determined according to the initialized grid-level spectral efficiency model of the first grid region and the mth preconfigured transmission mode.

By the above method, the spectral efficiency of the downlink channel of the at least one grid region in the cell can be determined, and then the spectral efficiency of the downlink channel of the cell can be determined. The spectral efficiency of the downlink channel of a cell is determined by the spectral efficiency of the downlink channel of all grid areas under the cell, and may include, but is not limited to, any of the following methods:

1. the sum of the frequency spectrum efficiencies of the downlink channels of all the grid areas under the cell is used as the frequency spectrum efficiency of the downlink channel of the cell;

2. the arithmetic mean value of the frequency spectrum efficiency of the downlink channels of all the grid areas under the cell is used as the frequency spectrum efficiency of the downlink channels of the cell;

3. the weighted average of the frequency spectrum efficiency of the downlink channels of all grid areas under the cell is used as the frequency spectrum efficiency of the downlink channels of the cell; for example, a cell includes two grid regions, where the first grid region has a weight of 0.7 and the second grid region has a weight of 0.3, and then the spectral efficiency of the downlink channel of the cell is 0.7 a1+0.3 a2, a1 is the spectral efficiency of the downlink channel of the first grid region, and a2 is the spectral efficiency of the downlink channel of the second grid region. It should be noted that the weight of the grid area in the cell may be configured according to an actual situation, for example, how to configure the weight may be based on statistics of services in the grid area, such as a ratio of actual users or a ratio of actual traffic, and the embodiment of the present application is not limited.

After determining the spectral efficiency of the downlink channel of the cell, if the spectral efficiency of the downlink channel of the cell meets a preset iteration stop condition, taking a period value in the mth preconfigured transmission mode as a transmission period of the uplink reference signal in the cell, taking a power value in the mth preconfigured transmission mode as a transmission power of the uplink reference signal in the cell, and taking a bandwidth value in the mth preconfigured transmission mode as a transmission bandwidth of the uplink reference signal in the cell.

Correspondingly, if the spectrum efficiency of the downlink channel of the cell does not meet the preset iteration stop condition, the (m + 1) th preconfigured transmission mode may be selected, and the above procedure is executed again, which is not described herein again.

It should be noted that, in the embodiment of the present application, the preset iteration stop condition is not limited. For example, in one possible implementation manner, the preset iteration stop condition may be: and according to the spectral efficiency of the downlink channel of the cell determined by the mth preconfigured transmission mode, the absolute value of the difference between the spectral efficiency of the downlink channel of the cell determined by any preconfigured transmission mode before the mth preconfigured transmission mode and the spectral efficiency of the downlink channel of the cell determined by any preconfigured transmission mode is less than a threshold value.

In another possible implementation, the preset iteration stop condition may be: and according to the spectral efficiency of the downlink channel of the cell determined by the mth preconfigured transmission mode, the absolute value of the difference between the spectral efficiency of the downlink channel of the cell determined by the m-1 preconfigured transmission mode and the spectral efficiency of the downlink channel of the cell is less than a threshold value.

In another possible implementation, the preset iteration stop condition may be: the iteration number K is less than or equal to a preset iteration number K, or the absolute value of the difference between the spectral efficiency of the downlink channel of the cell determined according to the mth preconfigured transmission mode and the spectral efficiency of the downlink channel of the cell determined according to the m-1 preconfigured transmission mode is less than a threshold value.

The above are only examples, and other preset iteration stop conditions are not illustrated one by one.

In the first possible implementation manner, the spectral efficiency of the downlink channel of each grid region in the cell is determined, and then the sum of the spectral efficiencies of the downlink channels of each grid region is used as the spectral efficiency of the downlink channel of the cell.

In another method, the grid-level spectrum efficiency models of at least one grid region in the cell may be combined into a spectrum efficiency model of the cell, that is, the spectrum efficiency model of the cell includes a plurality of formulas (1), so that the spectrum efficiency of the downlink channel of the cell may be directly obtained. The process of determining the spectral efficiency of the downlink channel in the grid region by each grid-level spectral efficiency model in the cell spectral efficiency models may refer to the foregoing description and is not described herein again.

In a second possible implementation manner, when a cell is not divided into grid regions, one cell may be regarded as one grid region, and then a spectrum efficiency model of the cell may be determined according to the wireless channel state data set, and then a transmission manner of an uplink reference signal in the cell may be determined according to the spectrum efficiency model.

The spectrum efficiency model is a model taking one or more of a transmission period variable, a transmission power variable and a transmission bandwidth variable as an independent variable and is used for determining the spectrum efficiency of a downlink channel of a cell.

The method specifically comprises the following steps:

step one, determining the cell level wireless channel state data of the cell according to the wireless channel state data set of the cell.

The cell-level wireless channel state data comprises data corresponding to one or more of the following parameters: path loss corresponding to the cell; transmitting power of an uplink reference signal corresponding to a cell; downlink single antenna SINR corresponding to the cell; and downlink average rank corresponding to the cell.

For example, the average of the radio channel state data sets of the cell may be used as the cell-level radio channel state data corresponding to the cell.

For another example, the median of the radio channel state data set of the cell may be used as the cell-level radio channel state data corresponding to the cell.

The above is only an example, and the cell-level radio channel status data may also be determined by other manners, which is not described herein again.

And step two, determining a cell level spectrum efficiency model of the cell according to the cell level wireless channel state data.

The cell-level spectrum efficiency model of the cell can refer to the formula (1), and only the parameters in the formula (1) need to be initialized by adopting the cell-level wireless channel state data and the uplink reference signal transmitting mode currently configured by the cell.

And step three, determining the transmitting mode of the uplink reference signal in the cell according to the cell-level spectrum efficiency model of the cell.

This step may refer to the description in the first possible implementation, and is not described herein again. When the determined spectrum efficiency of the downlink channel of the cell meets the preset iteration stop condition, a period value adopted by a transmission period variable of the cell-level spectrum efficiency model may be used as a transmission period of the uplink reference signal in the cell, a power value adopted by a transmission power variable of the cell-level spectrum efficiency model may be used as a transmission power of the uplink reference signal in the cell, and a bandwidth value adopted by a transmission bandwidth variable of the cell-level spectrum efficiency model may be used as a transmission bandwidth of the uplink reference signal in the cell.

In the embodiment of the present application, after determining the transmission mode of the uplink reference signal, the network device may send the transmission mode of the uplink reference signal to the terminal device in the cell managed by the network device through a signaling, and the terminal device in the cell may transmit the uplink reference signal in a corresponding transmission mode.
