Description

Measurement method and communication device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a measurement method and a communications apparatus.
Background
In current mobile communication systems, a User Equipment (UE) needs to periodically measure downlink signals to keep track of network cells. Radio Resource Management (RRM) measurements are used to support cell handover when the UE is in a Radio Resource Control (RRC) connected (connected) state, and to assist the UE in cell selection or reselection when the UE is in an RRC idle (idle) state.
In the prior art, the UE can only perform RRM measurement according to the time period specified by the protocol. The length of the time period specified by the protocol is fixed and invariable, so that the method is suitable for most communication scenes. However, in some communication scenarios, for example, in a case that a network environment where the terminal device is currently located is relatively stable, if the terminal device still performs RRM measurement according to a time period specified by the protocol, the terminal device may need to perform some unnecessary measurements, which increases power consumption of the terminal device.

Detailed Description
Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application are explained:
RRM measurement: RRM measurement refers to measurement of the current serving cell and the current serving cell by the terminal device. The terminal device may perform handover, selection, or reselection of the cell through RRM measurement.
In a fifth generation (5 th) network, the terminal device may perform downlink measurement on different signals in order to perform RRM measurement. In idle mode, the UE may measure the cell using a cell-specific SSB (synchronization signal block) to obtain the quality of the cell. In the connected mode, the UE may use a channel state information-reference signals (CSI-RS) dedicated to the UE in addition to the SSB for mobility measurement. When the terminal equipment carries out measurement in the same-frequency connection mode, at most 2 measurement window periods can be configured, so that the terminal equipment can conveniently measure different cells.
When performing RRM measurement on a cell, a terminal device typically performs RRM measurement according to a measurement requirement specified by an air interface protocol, and a time period of the RRM measurement is fixed. That is, the terminal device may perform the RRM cycle at a fixed time period. Alternatively, it can also be described that the time interval of two adjacent RRM measurements of the terminal device is fixed.
But in some scenarios, for example, the location of the terminal device changes little, or the terminal device is located at the cell center point. When the terminal device is in a small position change or is located at the center point of the cell, the communication environment of the terminal device is stable. In this case, the terminal device generally does not need to perform RRM measurement, and if the terminal device still performs RRM measurement, power consumption of the terminal device increases.
In order to solve the problem, an embodiment of the present application provides a measurement method, including: the network equipment acquires a plurality of signal quality parameters and moving speed of the terminal equipment in a first time period. And the network equipment determines the distance between the terminal equipment and the network equipment and the change index of the communication network of the terminal equipment in the first time period according to the read signal quality parameters, wherein the change index is used for representing the change condition of the communication network in the first time period. If the change index is smaller than the preset value, and the distance between the terminal device and the network device is smaller than the preset distance and/or the moving speed of the terminal device is smaller than the preset speed, the network device sends first indication information to the terminal device, wherein the first indication information is used for indicating that the time period of RRM measurement of the terminal device is a second time period, and the time length of the second time period is greater than the time length of the first time period.
In the method provided by the embodiment of the application, the network device determines the position information of the terminal device and the change condition of the communication network according to the plurality of signal quality parameters of the first time period. If the change condition of the communication network is small, the distance between the terminal device and the network device is greater than the preset distance, and/or the moving speed of the terminal device is less than the preset speed, it is indicated that the communication quality of the terminal device is better, and the communication network is more stable. Under the condition that the communication quality of the terminal device is good and the communication network is relatively stable, the network device may increase the time period of RRM measurement of the terminal device, that is, the network device reduces the frequency of RRM measurement of the terminal device, so that the terminal device may reduce power consumption.

Fig. 3 provides a measurement method for an embodiment of the present application, and as shown in fig. 3, the method includes:
step 301, the network device obtains a plurality of signal quality parameters and a moving speed of the terminal device in a first time period.
The network device may be any one of the network devices in fig. 1, such as network device 110 or network device 120. The terminal device may be the terminal device in fig. 1, such as terminal device 130.
The first time period is a time period configured in advance by the terminal device, and may be, for example, a time period specified by a protocol, or a time period indicated by the network device, which is not limited. The time period indicated by the network device refers to a time period determined by the network device according to the current network environment, the location information of the terminal device, and the moving speed, and specific reference may be made to the following description of the second time period, which is not described herein again.
The plurality of signal quality parameters may include a plurality of signal quality parameters in one time period, and may also include one or more signal quality parameters in each of a plurality of time periods. For example, the signal quality parameter may include at least one of a Reference Signal Receiving Power (RSRP), a signal to interference plus noise ratio (SINR), a Reference Signal Receiving Quality (RSRQ), a Received Signal Strength Indication (RSSI).
In one possible implementation, the network device may obtain, from a Measurement Report (MR) of the terminal device, a plurality of signal quality parameters of the terminal device for a first time period and a plurality of location change information of the terminal device. The position change information may include a plurality of coordinate information and corresponding times. The coordinate information may be latitude and longitude information. The network device may calculate the moving speed of the terminal device according to the plurality of pieces of coordinate information and the corresponding time.
Step 302, the network device determines the location information of the terminal device and the change index of the communication network of the terminal device in the first time period according to the plurality of signal quality parameters.
Wherein the location information of the terminal device may be determined based on a plurality of signal quality parameters. For example, the network device may determine the location information of the terminal device based on a difference between an average of the plurality of signal quality parameters and a signal quality parameter at an edge of a coverage area of the network device.
In one example, the network device may be preconfigured with signal quality parameters for the edge of the coverage area. The network device may calculate a difference between an average of the plurality of signal qualities and a signal quality parameter at an edge of the coverage area. If the difference is greater than the preset difference, it indicates that the terminal device is located within the preset range, or the distance between the terminal device and the network device is less than the preset distance. And under the condition that the terminal equipment is positioned in the preset range or the distance between the terminal equipment and the network equipment is less than the preset distance, the signal quality of the position where the terminal equipment is positioned is better or the network environment is stable. The preset range and the preset distance can be set according to needs and are not limited.
Wherein, the change index of the communication network can be used for representing the change condition of the communication network. For example, the change index of the communication network may be determined for the mean and variance of the signal quality parameter. For example, the change index of the communication network may be determined according to the following equation one.
F＝||R-E(R)|-S2(R) | formula one
Where F denotes a change index of the communication network. R represents a mean value of a plurality of signal quality parameters, and e (R) may represent a mean value of a signal quality parameter of a portion of the plurality of signal quality parameters. Alternatively, R represents a mean value of a signal quality parameter among the plurality of signal quality parameters, and e (R) may represent a mean value of the plurality of signal quality parameters. S2(R) represents the variance of a plurality of signal quality parameters.
It should be noted that the larger the change index of the communication network, the larger the change of the communication network. In the case where the signal quality parameter comprises a plurality of different signal quality parameters, the network device may determine the change index of the communication network based on any one of the signal quality parameters. For example, the change index of the communication network may refer to the smallest change index among the change indexes corresponding to the plurality of signal quality parameters.
For example, the signal quality parameters include RSRP and SINR, where the variation index corresponding to RSRP is F1The SINR has a variation index of F2. Wherein, F1Greater than F2. The variation index corresponding to the signal quality parameter is F2。
Step 303, if the change index of the communication network is smaller than the preset value, and the terminal device is located in the preset range and/or the moving speed of the terminal device is smaller than the preset speed, the network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device, and performs RRM measurement according to the first indication information.
The preset value and the preset speed can be set according to needs and are not limited. The change index of the communication network is smaller than the preset value, and the terminal device is located within the preset range and/or the moving speed of the terminal device is smaller than the preset speed may include the following three conditions:
in case 1, the change index of the communication network is smaller than a preset value, and the terminal device is located in a preset range.
And 2, the change index of the communication network is smaller than a preset value, and the moving speed of the terminal equipment is smaller than a preset speed.
And 3, the change index of the communication network is smaller than a preset value, the terminal equipment is located in a preset range, and the moving speed of the terminal equipment is smaller than a preset speed.
That is, when any of the above three cases is satisfied, the network device may transmit the first indication information to the terminal device, so that the terminal device may perform RRM measurement according to the second time period.
Wherein the first indication information may be used to indicate that a time period of RRM measurement of the terminal device is a second time period. Alternatively, the first indication information may be used to indicate the second time period. The second time period is greater than the first time period. The terminal device performing the RRM measurement according to the first indication information may mean that the terminal device may perform the RRM measurement according to the second time period.
In one example, the second time period may be M times the first time period. M is greater than 1.
The value of M may be determined according to the remaining power of the terminal device and a plurality of signal quality parameters.
The remaining power of the terminal device may be included in the MR, or the network device may acquire the remaining power of the terminal device through interaction with the terminal device. For example, the network device may transmit request information for requesting the remaining power of the terminal device to the terminal device. And after receiving the request information from the network equipment, the terminal equipment reports the residual electric quantity of the terminal equipment to the network equipment.
For example, the value of M may be determined according to equation two below.
M ═ 1/[ a + min (b, k + j) ] formula two
Wherein a and b are preset coefficients, and the values of a and b are in direct proportion to the residual capacity. k is determined based on a plurality of first signal quality parameters, j is determined based on a plurality of second signal quality parameters, and the first signal quality parameter and the second signal quality parameter are different signal quality parameters in the plurality of signal quality parameters.
For example, if the remaining capacity of the terminal device is less than the first threshold, a is 0.2, and b is 0.1; if the residual capacity of the terminal device is greater than or equal to the first threshold and less than the second threshold, a is 0.3, and b is 0.2; if the remaining capacity of the terminal device is greater than or equal to the second threshold and less than the third threshold, a is 0.5, and b is 0.4. The first threshold value is smaller than the second threshold value, and the second threshold value is smaller than or equal to the third threshold value. For example, the first threshold may be 30%, the second threshold may be 60%, and the third threshold may be 100%.
For example, k may be determined from the mean and variance of the plurality of first signal quality parameters and j may be determined from the mean and variance of the plurality of second signal quality parameters.
For example, the first signal quality parameter is RSRP, and the second signal quality parameter is SINR. Then k | | | RSRP-e (RSRP) | -S2(RSRP)|/S2(RSRP)。j＝||SINR-E(SINR)|-S2(SINR)|/S2(SINR). The description of the parameters in the two formulas can refer to the second formula, which is not repeated.
The value of M is calculated below in combination with the specific numbers.
Take the signal quality parameters of the terminal device including RSRP and SINR as an example.
The RSRP values in the MR reported by the terminal equipment are respectively as follows: 89 decibel millimeter (dbm), -90dbm, -86dbm, -94dbm, -96dbm, -87dbm, -86dbm, -81dbm, -97dbm, -94 dbm. The SINR values are: 14db, 17db, 24db, 19db, 18db, 21db, 18db, 22db, 23 db.
Wherein R is the average of the first 5 values of the plurality of RSRP values, i.e., -91 dbm. E (R) is the average of the RSRP values, i.e. E (R) -90dbm, S2(R) ═ 22.4. Alternatively, R is the average of the first 5 values among the SINR values, i.e., -20.8 db. E (R) is the average value of the SINR values, i.e. E (R) -20db, S2(R)＝10.8。
The network device may determine R, E (R) and S according to the above equation one, the above RSRP2The value of (R) is calculated as the change index F of the communication network 21.4, k ≈ 0.96.
The network device may determine R, E (R) and S according to the above equation one, the above SINR2The value of (R) is calculated as the change index F of the communication network 10, j 0.93.
If the preset value is 30. That is, the change index of the communication network corresponding to any one of the signal quality parameters is smaller than the preset value.
If the remaining capacity of the terminal device is 50%, it can be seen from the above that a is 0.3 and b is 0.2. Then M is 2. That is, the time length of the second time period is 2 times that of the first time period. For example, the first time period is 60 milliseconds (ms), and the second time period is 120 ms.
In another example, M may also be 1. In this case, the terminal device may perform RRM measurement according to the time period indicated by the network device, or may perform measurement according to a preset time period.
Based on the technical solution shown in fig. 3, the network device determines the location information of the terminal device and the change situation of the communication network according to the multiple signal quality parameters of the first time period. If the change condition of the communication network is small, the distance between the terminal device and the network device is greater than the preset distance, and/or the moving speed of the terminal device is less than the preset speed, it is indicated that the communication quality of the terminal device is better, and the communication network is more stable. Under the condition that the communication quality of the terminal device is good and the communication network is relatively stable, the network device may increase the time period of RRM measurement of the terminal device, that is, the network device reduces the frequency of RRM measurement of the terminal device, so that the terminal device may reduce power consumption.
