Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method and device for configuring a sounding reference signal (SRS) period. Background Art

[0002] The sounding reference signal (SRS) is an uplink reference signal sent by a terminal device to a network device. It is used to estimate uplink channel performance and provide a reference for uplink resource scheduling and downlink beamforming.

[0003] In the prior art, SRS signals can be sent periodically, and the configuration of the SRS period is closely related to the number of users in the cell. When the number of users in the cell is small, configuring a shorter SRS period can guarantee the user's downlink beamforming (BF) performance as much as possible. When the number of users in the cell is large, configuring a longer SRS period can guarantee the user's basic SRS measurement performance and avoid dropped calls due to the lack of SRS resources allocated to some users. However, the adjustment of the SRS period requires reconfiguring the user's SRS resources through radio resource control (RRC) signaling. If the SRS period is adjusted in real time according to the number of users in the cell, in scenarios such as when the number of users fluctuates greatly in a short period of time or when the number of users is not counted in a timely and accurate manner, the SRS period will be adjusted too frequently, resulting in huge signaling overhead. Summary of the Invention

[0004] The embodiments of the present application provide a method and apparatus for configuring a sounding reference signal (SRS) period, so as to effectively configure the SRS period and reduce signaling overhead.

[0005] In the first aspect, an embodiment of the present application provides a method for configuring a sounding reference signal (SRS) period, which can be executed by a communication device, such as a network device or a chip in a network device. The method includes: the communication device obtains the number of wireless resource control (RRC) connected users of at least one neighboring area of ​​a first cell within a first time period, predicts the number of RRC connected users of the first cell within a second time period based on the number of RRC connected users of at least one neighboring area of ​​the first cell within the first time period, and configures the SRS period for terminal devices accessing the first cell within the second time period based on the predicted number of RRC connected users of the first cell within the second time period.

[0006] With the above design, the communication device can predict the number of RRC-connected users of the first cell in the second time period based on the number of RRC-connected users in at least one neighboring cell of the first cell in the first time period before the second time period arrives, and then configure the SRS period for the terminal equipment accessing the first cell in the second time period. It can be seen from this that the communication device can pre-configure the SRS period available in the second time period for the first cell, and there is no need to reconfigure it in the second time period, thereby avoiding the problem of too frequent SRS period adjustment and effectively reducing the signaling overhead of SRS period configuration. At the same time, the configured SRS period can be made consistent with the access situation of the first cell in the second time period.

[0007] In a possible design of the first aspect, for each of at least one neighboring cell of the first cell, the number of RRC-connected users of the neighboring cell in the first time period includes the number of RRC-connected users of the neighboring cell at each moment in the first time period. In this way, the predicted number of RRC-connected users of the first cell in the second time period may be the sum of the number of RRC-connected users of at least one neighboring cell of the first cell at the first moment in the first time period, wherein the sum of the number of RRC-connected users of the at least one neighboring cell at the first moment is greater than or equal to the sum of the number of RRC-connected users of the at least one neighboring cell at other moments in the first time period. Alternatively, it can also be understood that the predicted number of RRC-connected users of the first cell in the second time period is the maximum value that the sum of the number of RRC-connected users of at least one neighboring cell of the first cell can reach in the first time period.

[0008] With the above design, since the number of users of the first cell in the second time period can be predicted based on the maximum value of the sum of the number of RRC-connected users of at least one neighboring cell of the first cell in the first time period before the second time period, the maximum number of RRC-connected users that may access the first cell in the second time period can be obtained. By configuring the SRS period in the second time period based on the maximum number of RRC-connected users, the problem of dropped calls caused by the inability to allocate SRS resources for some terminal devices when a large number of terminal devices access the first cell in batches in the second time period can be effectively avoided.

[0009] In a possible design of the first aspect, the communication device may set an SRS period for a terminal device accessing the first cell during the second time period based on a predicted number of RRC-connected users of the first cell during the second time period, and a mapping relationship between the number of RRC-connected users and the SRS period. The mapping relationship between the number of RRC-connected users and the SRS period may be predefined or preconfigured in the communication device. Furthermore, the mapping relationship may be adjusted by the communication device as needed.

[0010] In one possible design of the first aspect, the communications device may count the number of RRC-connected users of the first cell in real time, and send (e.g., periodically) the counted number of RRC-connected users of the first cell to at least one neighboring cell of the first cell. The real-time counted number of RRC-connected users of the first cell is used to configure an SRS period for each neighboring cell. In this way, each neighboring cell of the first cell may also be able to configure the SRS period in the same or similar manner as the first cell, thereby effectively reducing the signaling overhead of configuring the SRS period.

[0011] In the second aspect, an embodiment of the present application provides another method for configuring a sounding reference signal (SRS) period, which can be executed by a communication device, such as a network device or a chip in a network device, and the method includes: the communication device obtains historical statistical data of the number of RRC-connected users of the first cell within a change period, and the change period includes multiple time periods, and the historical statistical data includes the number of RRC-connected users of the first cell in each time period within the change period; the communication device predicts the number of RRC-connected users of the first cell in a third time period based on the number of RRC-connected users of the first cell in a time period that is at the same position as the third time period in a change period; the communication device configures the SRS period for terminal devices accessing the first cell in the third time period based on the predicted number of RRC-connected users of the first cell in the third time period.

[0012] With the above design, the communication device can predict the number of RRC-connected users in the first cell during the third time period based on the historical changes in the number of RRC-connected users in the first cell before the third time period arrives, thereby configuring the SRS period for terminal devices accessing the first cell during the third time period. In this way, the communication device can pre-configure the SRS period available for the first cell during the third time period, eliminating the need for reconfiguration during the third time period. This avoids the problem of overly frequent SRS period adjustments and effectively reduces the signaling overhead of SRS period configuration. At the same time, the configured SRS period can be made consistent with the access conditions of the first cell during the third time period.

[0013] In a possible design of the second aspect, the communication device obtaining historical statistical data of the number of RRC connected users of the first cell within a change period may include: the communication device obtaining the number of RRC connected users of the first cell within a past set time range, determining the change period based on the number of RRC connected users of the first cell within the past set time range, the set time range including multiple change periods; for each time period in a change period, the communication device determining the number of RRC connected users of the first cell in the time period in the historical statistical data based on the number of RRC connected users of the first cell in the time period among the multiple change periods included in the set time range. In this way, the historical statistical data of the number of RRC connected users of the first cell within a change period can reflect the changing pattern of the number of RRC connected users of the first cell, thereby providing guidance for predicting the number of RRC connected users of the first cell in a third time period.

[0014] In a possible design of the second aspect, the number of RRC connected users of the first cell in this time period in the historical statistical data may be the average value of the number of RRC connected users of the first cell in this time period in multiple change cycles included in the set time range; or, the number of RRC connected users of the first cell in this time period in the historical statistical data may be the value of the number of RRC connected users of the first cell in this time period in multiple change cycles included in the set time range after data filtering; or, the communication device may also determine the number of RRC connected users of the first cell in this time period in the historical statistical data based on the cumulative distribution curve of the number of RRC connected users of the first cell in this time period in multiple change cycles included in the set time range.

[0015] With the above design, the communication device can use a variety of possible methods to determine the specific values ​​of the number of RRC connected users corresponding to each time period of a change cycle of the number of RRC connected users in the first cell in the historical statistical data, thereby effectively improving the flexibility of the SRS period configuration method.

[0038] Network device 110 is a device that provides wireless communication capabilities for terminal devices. A network device can be a node in a radio access network, also known as a base station or a radio access network (RAN) node (or device). The network device can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the terminal device and the rest of the access network, which may include an IP network.

The terminal device can be used in, but is not limited to, 5G, 6G, or even 7G communication systems.

[0041] As an example and not a limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0043] It should be understood that there may be multiple network devices in the communication system 100, and each network device can provide services for multiple terminal devices. The embodiment of the present application does not limit the number of access network devices and terminal devices in the communication system. Figure 1 The access network device in the embodiment, as well as some of the terminal devices in the multiple terminal devices or each of the terminal devices in the embodiment can implement the technical solution provided in the embodiment of the present application.

[0044] It should also be understood that the terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" refers to two or more. In view of this, "multiple" can also be understood as "at least two" in the embodiments of the present application. "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then the included ones may be A, B, C, A and B, A and C, B and C, or A and B and C. Similarly, the understanding of descriptions such as "at least one" is similar. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the related objects before and after are in an "or" relationship.

[0046] Example 1

[0047] Please refer to Figure 2 , is a flow chart of a method for configuring a sounding reference signal (SRS) period provided in an embodiment of the present application, the method comprising the following steps:

[0048] Step S201: The communication device obtains the number of RRC connected users in at least one neighboring cell of a first cell within a first time period.

[0049] In the embodiment of the present application, the communication device may be Figure 1The network device or chip in the network device in the communication system shown in the figure may include one or more cells under the coverage of the communication device. The first cell refers to one of the cells covered by the communication device. The at least one neighboring area of ​​the first cell may include a cell covered by the communication device, or may include a cell covered by other communication devices (such as other network devices), which is not limited in this application.

[0050] If a neighboring cell among the at least one neighboring cell and the first cell are both covered by the communication device, the communication device may directly obtain the number of RRC connected users in the neighboring cell during the first time period, for example, by directly reading it from a memory. If a neighboring cell and the first cell are covered by different communication devices, the communication device may obtain the number of RRC connected users in the neighboring cell during the first time period from another communication device that has jurisdiction over the neighboring cell through an interface between communication devices.

[0051] The first time period may include multiple moments. For each neighboring cell of at least one neighboring cell of the first cell, the number of RRC connected users of the neighboring cell in the first time period includes the number of RRC connected users of the neighboring cell at each moment in the first time period.

[0052] Step S202: The communication device predicts the number of RRC connected users of the first cell in a second time period based on the number of RRC connected users of at least one neighboring cell of the first cell in the first time period, where the second time period is after the first time period.

[0053] In an embodiment of the present application, the communication device may predict the number of RRC connected users of the first cell within the second time period before the second time period arrives, wherein the predicted number of RRC connected users of the first cell within the second time period is used to configure the SRS period of the first cell within the second time period, that is, the period for sending SRS signals by terminal devices accessing the first cell within the second time period.

[0054] Specifically, the communication device may predict the number of RRC connected users of the first cell in the second time period in the following manner:

[0055] For each moment in the first time period, the communication device sums the number of RRC connected users of at least one neighboring cell of the first cell at that moment to obtain a sum value, and then takes the maximum value of the sum values ​​corresponding to each moment included in the first time period as the predicted number of RRC connected users of the first cell in the second time period.

[0056] That is to say, assuming that in the first time period, the sum of the number of RRC-connected users of at least one neighboring area of ​​the first cell reaches a maximum value at the first moment, then the predicted number of RRC-connected users of the first cell in the second time period is the sum of the number of RRC-connected users corresponding to at least one neighboring area of ​​the first cell at the first moment, that is, the maximum value of the sum of the number of RRC-connected users of at least one neighboring area of ​​the first cell. It can be understood that the sum of the number of RRC-connected users corresponding to the at least one neighboring area at the first moment is greater than or equal to the sum of the number of RRC-connected users corresponding to the at least one neighboring area at other moments in the first time period.

[0057] It should be understood that in the embodiments of the present application, the first time period is located before the second time period, and the first time period may be adjacent to or not adjacent to the second time period. The relationship between the first time period and the second time period may be configured by the communication device, or may be predefined or preconfigured, and is not limited by this application. In addition, the duration of the first time period and the second time period may be the same or different, and is not limited by this application.

[0058] Step S203: The communication apparatus configures an SRS period for the terminal device accessing the first cell in the second time period according to the predicted number of RRC connected users of the first cell in the second time period.

[0059] Specifically, the communication device configures an SRS period for a terminal device accessing the first cell during the second time period based on the predicted number of RRC-connected users of the first cell during the second time period, and the mapping relationship between the number of RRC-connected users and the SRS period. The mapping relationship between the number of RRC-connected users and the SRS period can be configured by the communication device, or can be predefined or preconfigured, and can also be adjusted by the communication device in a timely manner as needed, which is not limited in this application.

[0060] By adopting the above technical solution, the communication device can predict the number of RRC-connected users of the first cell in the second time period based on the number of RRC-connected users of at least one neighboring cell of the first cell in the first time period before the second time period arrives, and then configure the SRS period for the terminal equipment accessing the first cell in the second time period. It can be seen from this that the communication device can pre-configure the SRS period available in the second time period for the first cell, and there is no need to reconfigure it in the second time period, thereby avoiding the problem of too frequent SRS period adjustment and effectively reducing the signaling overhead of SRS period configuration. At the same time, the configured SRS period can be made consistent with the access situation of the first cell in the second time period.

[0061] Furthermore, in an embodiment of the present application, the communication device may periodically configure the SRS period of the first cell using the duration of the second time period as a period. That is, the communication device may configure the SRS period for the first cell once every second time period. Accordingly, steps S201 to S203 may be repeatedly performed using the duration of the second time period as a unit, and are performed once every second time period. In this way, the SRS period of the first cell can be adjusted in a timely manner to meet the communication needs of the terminal device.

[0062] The technical solution provided in the embodiment of the present application can also be applied in high-speed scenarios, such as Figure 3 The high-speed rail scenario shown. In the high-speed scenario, the terminal device has the characteristics of high-speed movement, rapid entry and exit of the cell, and batch entry and exit of the cell. Due to the high-speed movement of the terminal device, the number of RRC-connected users in the cell may also change rapidly. If the SRS period is configured according to the real-time statistical number of RRC users, it is possible that due to the existence of signaling delay, the configuration speed of the SRS period cannot keep up with the moving speed of the terminal device, resulting in inaccurate SRS period configuration and the need for repeated reconfiguration. In the embodiment of the present application, since the number of users of the first cell in the second time period can be predicted based on the sum of the maximum number of RRC-connected users of at least one neighboring cell of the first cell in the first time period before the second time period, the maximum number of RRC-connected users that may access the first cell in the second time period can be obtained. The SRS period in the second time period is configured according to the maximum number of RRC-connected users, which can effectively avoid the problem of dropped calls caused by the inability to allocate SRS resources to some terminal devices when a large number of terminal devices access the first cell in batches in the second time period.

[0063] For example, if Figure 3 As shown, the first cell is deployed along the high-speed rail line, and the number of RRC connected users is as follows: Figure 4 The changing pattern shown is that when a high-speed train passes, a large number of terminal devices quickly enter the cell, and the number of RRC connected users in the first cell quickly reaches a peak. After the high-speed train passes, the number of RRC connected users in the first cell quickly returns to a lower level and remains basically stable.

[0064] By adopting the technical solution provided in the embodiment of the present application, the communication device can set the duration of the second time period to the average time required for a high-speed train to pass through the first cell based on information such as the cell attributes of the first cell, the train timetable, and the train passenger capacity, and set the duration of the first time period to be less than the minimum departure interval between two high-speed trains that are adjacent in time in the first cell.

[0065] The communication device can also periodically configure the SRS period of the first cell based on the duration of the second time period. Specifically, the communication device can determine the period before the second time period as the first time period before each second time period arrives, and calculate the maximum value of the sum of the number of RRC-connected users of each neighboring area of ​​the first cell in the first time period. For example, the duration of the second time period can be 15s, and the first time period can be 15s, 10s or 5s before the second time period. Whenever a second time period is about to arrive, the communication device can obtain the number of RRC-connected users of each neighboring area of ​​the first cell in the first 15s, 10s or 5s before the second time period. Subsequently, the communication device determines the maximum value of the sum of the number of RRC-connected users of each neighboring area of ​​the first cell in the first time period as the predicted number of RRC-connected users of the first cell in the second time period. Furthermore, the communication device can configure the SRS period for the terminal equipment accessing the first cell in the second time period based on the predicted number of RRC-connected users of the first cell in the second time period.

[0066] like Figure 5 As shown, the first cell and each of its neighboring cells are geographically close, and a train passing through the neighboring cells of the first cell may also pass through the first cell. That is, in a high-speed rail scenario, when a train passes through the neighboring cell of the first cell, the number of RRC-connected users in the neighboring cell of the first cell may be quickly transmitted to the first cell, causing a surge in the number of RRC-connected users in the first cell. In this way, by calculating the sum of the number of RRC-connected users of at least one neighboring cell of the first cell in the first time period before the second time period, the number of RRC-connected users of the first cell in the second time period is predicted, and the SRS period of the first cell in the second time period is configured in advance based on the predicted number of RRC-connected users of the first cell in the second time period. This can effectively avoid the problem of untimely configuration of the SRS period and excessive reconfiguration signaling overhead due to the adjustment speed of the SRS period not keeping up with the moving speed of the train, thereby meeting the mobility requirements of the terminal device.

[0067] In one possible design, in an embodiment of the present application, the communication device may also count the number of RRC-connected users in the first cell in real time, and periodically send the counted number of RRC-connected users of the first cell to at least one neighboring cell of the first cell. The counted number of RRC-connected users of the first cell can be used to configure the SRS period for the neighboring cell. Accordingly, in step S201, each neighboring cell of the first cell may also count the number of RRC-connected users in its own cell in real time, and periodically send it to the first cell, so that the communication device uses the number of RRC-connected users counted by the neighboring cell to execute steps S201 to S203 to configure the SRS period for the first cell. It should be understood that the period for each neighboring cell of the first cell to send the counted number of RRC-connected users to the first cell may be the same as or different from the duration of the first time period and the duration of the second time period, and this is not limited by the present application.

[0068] Example 2

[0069] Please refer to Figure 6 , is a flow chart of another method for configuring a sounding reference signal (SRS) period provided in an embodiment of the present application, the method comprising the following steps:

[0070] Step S601: The communication device obtains historical statistical data of the number of RRC connected users of a first cell within a change cycle, where the change cycle includes multiple time periods, and the historical statistical data includes the number of RRC connected users of the first cell in each time period within the change cycle.

[0071] In an embodiment of the present application, the number of RRC connected users of the first cell may have a periodic change pattern, and the historical statistical data of the number of RRC connected users of the first cell within a change period can be used to reflect the change pattern of the number of RRC connected users of the first cell. The change period can be understood as the period of periodic change of the number of RRC connected users of the first cell.

[0072] Specifically, the historical statistical data of the number of RRC connected users of the first cell within a change period can be obtained in the following manner:

[0073] First, the communication device may obtain the number of RRC connected users in the first cell within a set time range in the past. In order to obtain sufficient historical data to refine the changing pattern of the number of RRC connected users in the first cell, the set time range may be set to be longer, for example, it may be set to the past 1 month, 2 months, or even 6 months. It should be understood that the set time range may be configured by the communication device, or may be predefined or configured, and this application is not limited thereto.

[0074] Subsequently, the communication device may determine a change period for the number of RRC connected users based on the number of RRC connected users in the first cell within a set time range in the past, where the set time range includes multiple change periods. This step may also be understood as determining a period for periodic changes in the number of RRC connected users in the first cell. For example, the change period may be 1 day, 2 days, 3 days, 1 week, 2 weeks, etc. If the change period is 1 week, it may indicate that the change in the number of RRC connected users in the first cell is the same or similar in each week.

[0075] Furthermore, for each time period in a change cycle, the communication device can determine the number of RRC connected users of the first cell in the time period in the historical statistical data based on the number of RRC connected users in the time period in multiple change cycles included in the first cell within the set time range. For example, in one possible implementation, the communication device may determine the average value of the number of RRC connected users of the first cell in the time period in multiple change cycles included in the set duration as the number of RRC connected users of the first cell in the time period in the historical statistical data; or, in another possible design, the communication device may also perform data filtering (such as ALPHA filtering method) on the number of RRC connected users of the first cell in the time period in multiple change cycles included in the set duration to obtain the number of RRC connected users of the first cell in the time period in the historical statistical data; or, in another possible design, the communication device further determines the number of RRC connected users of the first cell in the time period in the historical statistical data based on the cumulative distribution curve (CDF curve) of the number of RRC connected users of the first cell in the time period in multiple change cycles included in the set duration. For example, a CDF curve may be drawn based on the number of RRC connected users of the first cell in the time period in multiple change cycles included in the set duration, and then the value corresponding to the x% point in the CDF curve is taken as the number of RRC connected users of the first cell in the time period in the historical statistical data.

[0076] In order to accurately reflect the changing pattern of the number of RRC connected users in the first cell, in an embodiment of the present application, the communication device may divide a change cycle of the number of RRC connected users in the first cell into multiple time periods. A time period can be understood as the statistical granularity of the statistical data of the number of RRC connected users in the first cell in time, that is, one time period corresponds to the statistical data of the number of RRC connected users in one first cell. For example, a change cycle can be 1 week, and a time period is 15 minutes. The communication device can divide a change cycle into multiple time periods according to the time granularity of each 15 minutes, and determine the statistical data of the number of connected users in the first cell corresponding to each time period one by one.

[0077] In this way, the communication device can obtain the number of RRC connected users of the first cell in each time period in a change cycle, thereby obtaining historical statistical data of the number of RRC connected users of the first cell in a change cycle, that is, the change pattern of the number of RRC connected users of the first cell. The change pattern of the number of RRC connected users of the first cell can also be expressed as follows: Figure 7 The function curve shown may also be in the form of a data table or other charts, which is not limited in this application.

[0078] Step S602: The communication device predicts the number of RRC connected users of the first cell in the third time period according to the number of RRC connected users of the first cell in the time period that is at the same position as the third time period in the change cycle.

[0079] Step S603: The communication apparatus configures an SRS period for a terminal device accessing the first cell in the third time period according to the predicted number of RRC connected users of the first cell in the third time period.

[0080] For example, the communication device wants to configure the SRS period of the first cell in the third time period. If the change period of the number of RRC connected users of the first cell is 1 week, one period is 15 minutes, and the third period is from 10:00 to 10:15 a.m. on a Monday, then before the arrival of the third time period, the communication device can, based on the historical statistical data of the number of RRC connected users of the first cell in a change period, determine the number of RRC connected users of the first cell corresponding to 10:00 to 10:15 a.m. on Monday in the historical statistical data as the predicted number of RRC connected users of the first cell in the third time period, and then configure the SRS period for the terminal equipment accessing the first cell in the third time period based on the predicted number of RRC connected users of the first cell in the third time period.

[0081] By adopting the above technical solution, the communication device can predict the number of RRC connected users of the first cell in the third time period based on the historical change pattern of the number of RRC connected users of the first cell before the arrival of the third time period, thereby configuring the SRS period for the terminal equipment accessing the first cell in the third time period. It can be seen from this that the communication device can pre-configure the SRS period available in the third time period for the first cell, and there is no need to reconfigure it in the third time period, thereby avoiding the problem of too frequent SRS period adjustment and effectively reducing the signaling overhead of SRS period configuration. At the same time, the configured SRS period can be made consistent with the access situation of the first cell in the third time period.

[0082] It should be noted that the two methods of configuring the SRS period provided in the embodiments of the present application can be understood as two ways of configuring the SRS period. The communication device can determine the application scenario of the first cell according to the cell attributes of the first cell, and then select the method of configuring the SRS period for the first cell. For example, if the first cell is deployed along the high-speed rail line, then considering that the terminal equipment in the first cell may move at high speed and cut in and out in batches, the communication device can adopt the method of configuring the SRS period described in Example 1; if the first cell is deployed in a large public place (such as a stadium, campus, teacher, station, traffic light, etc.), then considering that there may be a large number of users in the first cell who cut in and out collectively in a short period of time, but will not move at high speed, the communication device can adopt the method of configuring the SRS period described in Example 2. It should be understood that the technical features described in the above two embodiments can also be used in combination with each other, and this application is not limited.

[0083] The present application also provides a communication device. Figure 8 , is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. The communication device 800 includes a transceiver module 810 and a processing module 820. The communication device can be used to implement the functions of the communication device in any of the above method embodiments. For example, the communication device can be a network device or a chip included in the network device.

[0084] When the communication device acts as a network device, executing Figure 2 In the method embodiment shown in , the transceiver module 810 is used to obtain the number of radio resource control RRC connected users of at least one neighboring area of ​​the first cell within a first time period; the processing module 820 is used to predict the number of RRC connected users of the first cell in a second time period based on the number of RRC connected users of at least one neighboring area of ​​the first cell within the first time period, and the second time period is after the first time period, and according to the predicted number of RRC connected users of the first cell in the second time period, the SRS period is configured for the terminal device accessing the first cell in the second time period.

[0085] In one possible design, the number of radio resource control RRC connected users of each neighboring cell in the first time period includes the number of RRC connected users of the neighboring cell at each moment in the first time period; the predicted number of RRC connected users of the first cell in the second time period is: the sum of the number of RRC connected users of at least one neighboring cell of the first cell at the first moment in the first time period, and the sum of the number of RRC connected users of the at least one neighboring cell at the first moment is greater than or equal to the sum of the number of RRC connected users of the at least one neighboring cell at other moments in the first time period.

[0086] In one possible design, the processing module 820 is specifically used to set the SRS period for the terminal device accessing the first cell in the second time period based on the predicted number of RRC connected users of the first cell in the second time period and the mapping relationship between the number of RRC connected users and the SRS period.

[0087] In one possible design, the processing module 820 is also used to count the number of RRC connected users of the first cell in real time; the transceiver module 810 is also used to periodically send the counted number of RRC connected users of the first cell to at least one neighboring cell of the first cell, and the real-time counted number of RRC connected users of the first cell is used to configure the SRS period for each neighboring cell.

[0088] It should be understood that the processing module 820 involved in the communication device can be implemented by a processor or a processor-related circuit component, and the transceiver module 810 can be implemented by a transceiver or a transceiver-related circuit component.
