Detailed Description
The embodiment of the invention provides a channel detection period configuration method, a base station, equipment and a medium, which are used for realizing flexible adjustment of channel detection period configuration so as to improve the frequency spectrum utilization rate.
In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In current 5G communication systems, sounding reference signals (sounding reference signal, SRS) are used to estimate the uplink channel quality for different frequency bands. The scheduler at the base station side can allocate those Resource Blocks (RBs) with good instantaneous channel states to the uplink physical shared channel (physical uplink shared channel, PUSCH) transmission of the terminal (UE) according to the "uplink channel state estimation", and can select different transmission parameters (e.g., instantaneous data rate) and be used for the "uplink frequency selective scheduling".
In the current system, the set of subframe numbers available for transmitting SRS in one cell is by IE: the cell level resource configuration field of Sounding is configured with the srs-subframe configuration field of Sounding rs-UL-ConfigCommon, which is a cell level configuration. The correspondence of srs-subframeConfig to T Table 5.5.3.3-2 of 36.211 is shown in FIG. 1. The unit-specific configuration 103 can be divided into two cases 101 and 102, where 101 is a schematic diagram of a protocol stack Table in frequency division duplex (frequency division duplexing, FDD), and 102 is a schematic diagram of a protocol stack Table in time division duplex (time division duplexing, TDD), and compared to this Table in the protocol, 1 column is added last, and a subframe set available for transmitting SRS in each system frame in each configuration is given.
It can be seen that at least one SRS symbol is currently configured per frame, and in the worst case (SRS transmission per subframe), SRS may occupy about 7% (1/14, i.e. one of 14 symbols per frame) of overhead. However, in some low-speed scenarios, SRS sounding is not required so frequently, resulting in spectrum waste, and bandwidth resources are strained when traffic is large.
Therefore, in order to solve the above-mentioned problem, the embodiments of the present application provide a channel sounding period configuration method, which adjusts a channel sounding period according to a moving speed of a terminal, so as to adaptively adjust a cell resource allocated to an SRS according to a state of a cell, thereby improving a spectrum utilization rate. For ease of understanding, the methods provided herein are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, as shown in fig. 2, a first embodiment of a channel sounding period configuration method provided in an embodiment of the present application includes the following steps.
201. The base station acquires the moving speed of the terminal.
In this embodiment, the moving speed is the moving speed of the terminal relative to the base station. In a specific working process, the base station can determine the moving speed of the terminal by calculating Doppler frequency offset, and can determine the moving speed of the terminal by the beam direction under a time division duplex working scene. For ease of understanding, the following detailed description is provided with reference to the accompanying drawings.
1. And the base station determines the moving speed of the terminal by calculating Doppler frequency offset.
In this embodiment, the terminal is a mobile terminal, and may specifically be a smart phone, a tablet computer, or a smart watch, as shown in fig. 3, in the process of moving the terminal 301 relative to the base station 302, for example, from point a to point b in fig. 3, the included angle between the base station 302 and the moving direction of the terminal 301 changes, so the method for determining the moving speed of the terminal through doppler frequency offset is as follows:
and the base station determines the moving speed of the terminal according to the change of the included angle between the moving direction of the terminal and the base station.
In this embodiment, in order to determine the moving speed of the terminal through the change of the included angle between the moving direction of the terminal and the base station, the following formula may be used for calculation.
In the above formula, f is the center frequency point of the base station, c is the speed of light, v is the moving speed of the terminal, θ is the included angle between the base station and the moving direction of the terminal, f d Is the distance between the base station and the terminal.
Thus, the moving speed v of the mobile terminal can be obtained through the formula.
2. The base station determines the moving speed of the terminal through the beam direction.
In this embodiment, in the TDD scenario, the moving speed of the terminal may also be determined by the beam direction. As shown in fig. 4, this is achieved specifically by the following steps.
401. The base station acquires target beams at different moments.
In this embodiment, the target beam is a beam that is beamformed and then directed to the terminal by the base station. In a 5G communication scenario, in order to increase channel capacity, a base station and a terminal use multiple antennas, and an antenna system of multiple channels is formed between transmission and reception, and communication is performed by a multiple-input multiple-output (multiple input multiple output, MIMO) method, in which a beam transmitted by the base station to the terminal needs to be beamformed.
402. The base station determines the moving speed of the terminal according to the correlation between the target beams at different moments.
In this embodiment, if the terminal is stationary relative to the base station, the beams transmitted from the base station to the terminal are the same at different times. Therefore, the base station can judge that the current terminal is in a static state through the same beam forming. Similarly, if the terminal moves relative to the base station, the beams sent by the base station to the terminal are different at the first time and the second time, and the base station judges the movement speed of the terminal by comparing the correlation of the two beams. For example, the beamforming situation of the front and rear moments is acquired every preset time period, and the larger the correlation between the two beams is, the slower the speed of the movement of the terminal is indicated, otherwise, the smaller the correlation between the two beams is, the faster the speed of the movement of the terminal is indicated.
In this embodiment, the judgment of the terminal moving speed is achieved through the correlation between the beams in the TDD scene in the manner described in steps 401 to 402.
In the manner described in fig. 3 or fig. 4, the base station determines the movement speed of the terminal, and further performs the subsequent steps based on the movement speed.
202. And the base station determines the channel detection period of the terminal according to the moving speed.
In this embodiment, the base station determines the channel sounding period according to the moving speed of the terminal, so as to dynamically adjust the channel sounding period. Specifically, the present invention relates to a method for manufacturing a semiconductor device. As shown in fig. 5, the specific operation mode of the base station for determining the channel sounding period of the terminal according to the moving speed includes the following steps.
501. When the moving speed is greater than or equal to a preset value, the base station shortens the channel detection period.
In this embodiment, a specific value of the preset value can be set by a person skilled in the art according to actual needs, and the embodiment of the present application is not limited thereto. When the moving speed is greater than or equal to the preset value, the current moving speed of the terminal is higher, the condition of the channel communicated with the base station is changed greatly, and the period of channel detection needs to be shortened at the moment, so that the method is suitable for the movement condition of the terminal.
Further, the method provided in the embodiments of the present application may be applied to a wireless communication system using SRS to estimate channel quality, where each period of channel quality detection by SRS symbols constitutes a period of channel detection, i.e. an SRS period, and when the base station detects that the current terminal moves at a relatively high speed, the SRS period is shortened to adapt to the change of the current working condition.
Specifically, the specific working mode of the SRS period is: the base station configures sounding reference signal SRS symbols in a target frame, wherein the target frame is at least one frame in the communication period of the base station and the terminal. The following steps need to be performed when the base station needs to shorten the channel sounding period.
The number of frames of the interval between the target frames is reduced.
In this embodiment, for example, one SRS symbol is configured for every 3 frames in the current channel sounding period, and when the base station needs to shorten the channel sounding period, the base station adjusts to configure one SRS symbol for every 2 frames, thereby shortening the channel sounding period. Thereby enabling the terminal to perform the detection of the channel quality more frequently in case of a fast movement with respect to the base station.
502. When the moving speed is smaller than a preset value, the base station prolongs the channel detection period.
In this embodiment, a specific value of the preset value can be set by a person skilled in the art according to actual needs, and the embodiment of the present application is not limited thereto. When the moving speed is smaller than the preset value, the current moving speed of the terminal is lower, the terminal is in a low-speed moving scene, at the moment, the change of the channel condition of the communication between the terminal and the base station is smaller, and the frequent detection of the channel quality is not needed. The period of channel sounding needs to be prolonged at this time, thereby saving spectrum resources in a low-speed scenario.
Further, the method provided by the embodiment of the application can be applied to a wireless communication system using SRS to estimate channel quality, wherein each period of channel quality detection through SRS symbols forms a period of channel detection, namely an SRS period, and when the base station detects that the current terminal moving speed is slower, the frequency spectrum utilization rate in a low-speed scene is improved by extending the SRS period, so that the adaptive adjustment of SRS cell resources is realized.
Specifically, the specific working mode of the SRS period is: the base station configures sounding reference signal SRS symbols in a target frame, wherein the target frame is at least one frame in the communication period of the base station and the terminal. The following steps need to be performed when the base station needs to extend the channel sounding period.
The number of frames of the interval between the target frames is increased.
In this embodiment, for example, one SRS symbol is configured for every 2 frames in the current channel sounding period, and when the base station needs to lengthen the channel sounding period, the base station adjusts to configure one SRS symbol for every 3 frames, thereby prolonging the channel sounding period. Therefore, the frequency of channel quality detection is reduced in the low-speed movement scene of the terminal, the spectrum utilization rate is improved, and the spectrum resources are saved.
Through the above steps shown in fig. 5, the base station determines the channel sounding period of the terminal according to the moving speed of the terminal, and at this time, further performs the following steps.
203. The base station reconfigures the user period of the terminal according to the channel detection period.
In this embodiment, the base station reconfigures the user period of the terminal according to the determined channel detection period, so that the base station and the terminal determine the channel quality according to the channel detection period. Unification is realized at the base station side and the terminal side.
The channel detection period configuration method provided by the embodiment of the application comprises the following steps: the base station acquires the moving speed of the terminal, wherein the moving speed is the moving speed of the terminal relative to the base station; the base station determines the channel detection period of the terminal according to the moving speed; the base station reconfigures the user period of the terminal according to the channel detection period, so that the base station and the terminal determine the channel quality according to the channel detection period. Therefore, the base station can adjust the channel detection period according to the moving speed of the terminal, thereby realizing the self-adaptive adjustment of the cell resources and improving the utilization rate of the frequency spectrum resources.
Further, the base station shortens or lengthens the channel detection period based on the original channel detection period, so that the period adjustment is dynamically realized in the process of communication between the base station and the terminal, and in order to facilitate understanding, a detailed working scheme of the channel detection period configuration method is provided below in combination with the accompanying drawings.
Referring to fig. 6, as shown in fig. 6, a second embodiment of a channel sounding period configuration method according to the present embodiment includes the following steps.
601. The base station acquires an initial channel sounding period of the terminal.
In this embodiment, the initial channel detection period may be a channel detection period that has not been adjusted by the method provided in the present application, or may be a channel detection period that has been adjusted by the method provided in the present application, which is not limited in this embodiment of the present application.
602. The base station acquires the moving speed of the terminal.
In this embodiment, the step 202 is referred to above, and will not be described herein.
603. And the base station adjusts the initial channel detection period according to the moving speed to obtain an updated channel detection period.
In this embodiment, the method for the base station to adjust the initial channel sounding period according to the moving speed may be specifically divided into the following steps.
And the base station shortens or prolongs the initial channel detection period according to the moving speed to obtain an updated channel detection period. Specifically, when the moving speed of the terminal is greater than or equal to a preset value, the base station shortens the initial channel sounding period, resulting in an updated channel sounding period that is shorter than the previous period. When the moving speed of the terminal is smaller than a preset value, the base station prolongs the initial channel detection period to obtain an updated channel detection period which is longer than the previous period. Alternatively, the specific manner in which the base station extends and shortens the period may refer to the foregoing description about fig. 5, which is not repeated here.
604. The base station reconfigures the user period of the terminal according to the updated channel detection period.
In this embodiment, the newly determined updated channel sounding period of the base station is different from the previous initial channel sounding period, so that the base station needs to reconfigure the user period of the terminal according to the determined channel sounding period, so that the base station and the terminal determine the channel quality according to the channel sounding period. Unification is realized at the base station side and the terminal side. Thereby completing the updating of the channel sounding period. The method is continuously and circularly executed in the process of communicating the base station and the terminal, thereby realizing the dynamic adjustment of the channel detection period.
The method may be implemented by one entity device, or may be implemented by a plurality of entity devices together, or may be a logic functional module in one entity device, which is not specifically limited in the embodiment of the present application.
