The establishment and adjustment of the ANR function for neighbor relation is based on the UE's measurement report, which when it indicates that a new neighbor may be found, the base station may request the UE to report CGI information of the cell. Using the CGI information, the ANR function is able to automatically create a neighbor relation between the serving cell and the neighbor cell to support cell handover. The measurement configuration process involved therein comprises: (1) selecting an edge user; (2) measurement of PCI (Physical Cell Identification, physical cell identity) (event, periodicity); (3) measurement of CGI. However, in practical application, due to uncertainty of the number, the positions and the motion trail of the edge users, a situation that a plurality of frequency points to be measured exist but the number of the edge UEs is relatively small occurs, and based on the principle that each UE needs to traverse and measure each frequency point to be measured, in the PCI measurement stage, the traditional scheme is to send all frequency points to each UE for measurement.

Referring to fig. 1, in a multi-cell networking environment, the number, the positions and the motion trajectories of the edge UEs have uncertainty, the distances between the neighboring cells and the edge UEs are different, and when the number of to-be-detected frequency points is large and the number of the edge UEs is small, if each UE only measures part of the frequency points, the situation that the neighboring cell 1 which should be added as the neighboring cell cannot be added because the distance between the UE and the measured neighboring cell is far (for example, the measured signal quality of the neighboring cell 1 is too low by the user B) occurs. The conventional technology is to issue all to-be-detected frequency points to all selected edge UE so as to avoid the situation of missing the adjacent cell. However, when the number of frequency points is large and the number of edge UEs is small, each UE allocates a plurality of frequency points to be measured, the measurement capability of the UE is limited and the UE can sequentially measure according to the list of frequency points to be measured, so that each round of measurement can only measure part of the frequency points in the front of the list, and other frequency points may not be measured.

Because the UE performs measurement according to the sequence of the list of frequency points to be measured, the conventional measurement configuration mode can cause that the UE can only measure the front frequency division point in each round of measurement, but cannot finish measurement on all frequency points to be measured, and each time of issuing measurement configuration needs to issue RRC (Radio Resource Control ) reconfiguration signaling through the base station, so that signaling overhead is large, repeated waste of resources and increase of time delay are caused, and normal service and user experience are affected. In addition, the measurement of the neighboring cell CGI by the UE needs a sleep period with the help of a DRX (Discontinuous Reception ) function, and the UE cannot be scheduled during the reading process, otherwise, the sleep period is interrupted, which results in a reduced success rate of reading the CGI.

The application can solve the problems that the UE cannot measure the low efficiency and high energy consumption of all the frequency points to be measured and the success rate of reading the CGI of the neighbor cell is lower in the PCI and CGI measurement process when the ANR function is started. Specifically, the application provides a scheme for indicating to schedule UE through DCI (Downlink Control Information ) to perform reasonable and efficient PCI and CGI measurement and improving the CGI reading success rate when an ANR function is started, so that the problems that the UE cannot measure all frequency points to be measured due to the fact that the number of measurement frequency points is large, and the CGI reading success rate is low are solved.

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. The terminal UE according to the present application is not limited to the 5G network, and includes: cell phones, internet of things equipment, smart home equipment, industrial control equipment, vehicle equipment and the like. The User equipment may also be referred to as a Terminal (Terminal), a Terminal Device (Terminal Device), a Mobile Station (Mobile Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and is not limited herein. The user equipment may also be an automobile in Vehicle-To-Vehicle (V2V) communication, a machine in machine type communication, or the like.

In addition, the base station according to the present application may be a Base Station (BS) device deployed in a radio access network to provide a UE with a wireless communication function, including macro base stations, micro base stations, relay stations, controllers, access points, etc. in various forms. In systems employing different radio access technologies, the names of devices with base station functions may be different, for example, in LTE networks, referred to as evolved NodeB (eNB), in third generation 3G networks, referred to as Node B (Node B), or communication nodes applied in fifth generation communication systems, NR base stations, gNB, etc., and other similar network devices may also be used.

The measurement method provided by the application can be applied to LTE systems, LTE Advanced (LTE-A), or other wireless communication systems adopting various wireless access technologies, such as systems adopting access technologies such as code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency division multiple access, carrier aggregation (Carrier Aggregation, CA) and the like. In addition, the method can also be suitable for using subsequent evolution systems, such as a fifth generation 5G system and the like. In particular, the present application is applicable to establishing, optimizing, and supporting an Automatic Neighbor Relation (ANR) for cell handover.

In one embodiment, as shown in fig. 2, a measurement method is provided, and the method is applied to a base station for illustration, and includes the following steps:

step 202, transmitting measurement indication information to each edge UE respectively; the measurement indication information is used for indicating the edge UE to perform physical cell identification code PCI measurement on each neighbor cell to be measured;

the measurement indication information comprises downlink control information DCI for indicating the measurement purpose and the measurement sequence of each round by adopting bits; the measurement purpose comprises the starting frequency point and the measurement number of the round, and the measurement sequence comprises the measurement of the frequency points from the starting frequency point until the measurement number is completed.

Specifically, under the condition that the physical cell identification code PCI measurement is determined to be performed on the neighbor cell to be measured, the base station in the application can issue a DCI (downlink control information) message to indicate the measurement behavior of the edge UE, and specifically can use bits (bit) to indicate the measurement purpose and the measurement sequence. And the edge UE may refer to a user equipment UE selected by the base station. In some examples, the ANR automatically adds neighbor function on, and to implement the ANR measurement, the base station may select an appropriate edge UE. In other examples, the number of edge UEs selected by the base station may be 1 or more.

In one embodiment, before the step of transmitting the measurement indication information to each edge UE, the method may further include the steps of:

and transmitting each frequency point to be tested to the edge UE through a Radio Resource Control (RRC) reconfiguration signaling.

Specifically, the base station can automatically add the opening of the neighbor cell function based on the ANR, and select the proper edge UE; and the base station can send all the frequency points to be detected to all the selected UE through the Radio Resource Control (RRC) reconfiguration signaling to guide the UE to carry out PCI measurement of the neighbor cell.

In some examples, the ANR automatically adds neighbor function on, and to implement ANR measurement, the base station selects a suitable edge UE; and then, the base station transmits all the frequency points to be tested to all the selected UE through RRC reconfiguration signaling to guide the UE to conduct PCI measurement of all the neighbor cells to be tested. The application guides the scheduling UE to carry out high-efficiency reasonable frequency point measurement through the downlink control information DCI, thereby avoiding excessive signaling overhead caused when the base station issues RRC reconfiguration signaling for many times to guide the UE to measure.

Further, the downlink control information DCI may indicate the measurement purpose and the measurement sequence of each round of the edge UE by using bits, for example, a new bit is used in the downlink control information DCI to indicate the measurement behavior of the edge UE.

In the physical cell identity PCI measurement per round of edge UE: the measurement purpose may include a start frequency point and a measurement number of the present round of measurement, and the measurement sequence of the present round of measurement may include measurement of the frequency point from the start frequency point until the measurement number is completed. The starting frequency point can be realized in a marking mode, for example, a frequency point to be detected with a corresponding number is selected from a plurality of frequency points to be detected as the starting frequency point, and the number is one of marking modes. In some examples, the number of measurements may be determined from the measurement per round of edge UE, e.g., 2 bins per round of UE measurement.

In one embodiment, the starting frequency point may be a frequency point with a preset ordering number in each frequency point to be tested which is arranged in order. Specifically, for all the frequency points to be tested, in each round of PCI measurement, the frequency point with the preset sequence number is used as the starting frequency point of the round, and is indicated by a bit. For example, in the first round of measurement, the corresponding identifier position of the downlink DCI may be 001 (i.e., the new bit of the DCI is 001), which is used to instruct the UE to start measurement from the first frequency point to be measured (i.e., the starting frequency point of the present round is the frequency point with the number of 1).

In one embodiment, the preset sort number may be an odd number. Specifically, the application can take the odd numbered frequency points as the initial frequency points of each round. It should be noted that, in the present application, other numbered frequency points may be used as the starting frequency point, for example, even numbered frequency points, so long as measurement of all frequency points to be measured can be completed.

The application controls the initial frequency point number measured by the UE through DCI, avoids a plurality of UEs to repeatedly measure the physical cell identification code PCI and the global cell identification code CGI of a certain frequency point, thereby avoiding the repeated waste of resources and the increase of time delay and reducing the measurement power consumption of the terminal. In addition, by adopting the measurement mode of the application, the problem that the UE only can measure the front frequency division point in each round of measurement and can not finish the measurement of all the frequency points to be measured when issuing all the frequency points to be measured to the UE under the condition that a plurality of frequency points to be measured exist but the number of the edge UE is relatively small can be avoided.

To further illustrate aspects of the application, the following description is provided in connection with specific examples:

referring to table 1, a single UE, multiple frequency points, and a DCI bit change process, that is, taking DCI scheduling single UE for measurement as an example; as shown in table 1, a single edge UE,5 frequency points to be measured, can measure 2 frequency points per round (PCI measurement), i.e. the number of measurements per round is 2. The corresponding identification position of the DCI issued by the first round of measurement is 001, and the UE is instructed to start measurement from the first frequency point to be measured (namely, the initial frequency point of the round is the frequency point with the number of 1); the corresponding identification position of the DCI issued by the second round of measurement is 011, and the UE is instructed to start measurement from the third frequency point to be measured (namely, the initial frequency point of the round is the frequency point with the number of 3); the DCI with the third round of measurement downlink identifier 101 indicates that the UE starts measurement from the fifth frequency point to be measured (i.e. the starting frequency point of the present round is the frequency point with the number of 5). And after three rounds of measurement, the UE completes PCI measurement on all the frequency points to be measured.

TABLE 1

Single UE measurement	DCI (data information center) newly added bit	Meaning of
			Wheel 1 measurement	001	Measurement from 1 st frequency point
Wheel 2 measurement	011	Measurement from the 3 rd frequency point
			Wheel 3 measurement	101	Measurement from the 5 th frequency point

Referring to table 2, the change process of DCI bit is exemplified by DCI scheduling multiple UEs to measure. As shown in table 2, there are 2 edge UEs, 6 frequency points to be measured, and the UE measures 2 frequency points per round (PCI measurement), i.e. the number of measurements per round is 2. The first round of measurement sends the DCI corresponding identification position to each UE at 001, and indicates the UE to start measurement from the first frequency point to be measured (namely, the starting frequency point of the round is the frequency point with the number of 1); the second round of measurement transmits DCI with the corresponding identification position of 011 to each UE, and the UE is instructed to start measurement from the third frequency point to be measured (namely, the starting frequency point of the round is the frequency point with the number of 3); the DCI with the third round measurement downlink identifier 101 indicates that each UE starts measurement from the fifth frequency point to be measured (i.e. the starting frequency point of the round is the frequency point with the number of 5). After three rounds of measurement, all the UE completes PCI measurement on all the frequency points to be measured.

TABLE 2

The application indicates the measurement behavior of the UE based on the DCI (downlink control information) message issued by the base station, and specifically indicates the measurement purpose and the measurement sequence by bit. Therefore, the situation that part of frequency points cannot be measured and the measurement is repeated is avoided, the power consumption of the terminal is reduced, and the influence of an ANR function on the time delay of the terminal is reduced.

Step 204, receiving a measurement report transmitted by an edge UE; the measurement report contains the PCI measurement results.

Specifically, after the PCI measurement is completed, the edge UE may report a measurement report; the measurement report may include PCI measurement results, such as PCI information of the UE reporting neighbor cells. In some examples, the PCI measurement result may further include information such as RSRP (Reference Signal Receiving Power, reference signal received power) of the UE reporting the neighbor cell.

In the measurement method, the DCI is used for guiding the scheduling UE to carry out efficient and reasonable frequency point measurement, so that excessive signaling overhead caused when the base station issues RRC reconfiguration signaling for many times to guide the UE to measure is avoided. The application controls the initial frequency point number measured by the UE through DCI, avoids a plurality of UEs to repeatedly measure the PCI and the CGI of a certain frequency point, thereby avoiding the repeated waste of resources and the increase of time delay and reducing the measurement power consumption of the terminal. Based on the application, the problem that the UE only can detect the front frequency division point in each round of measurement and can not finish the measurement of all the frequency points to be measured when issuing all the frequency points to be measured to the UE under the condition that a plurality of frequency points to be measured exist but the number of the edge UE is relatively small can be avoided.

In one embodiment, as shown in fig. 3, a measurement method is provided, and the method is applied to a base station for illustration, and includes the following steps:

in step 302, an edge UE is selected in case of automatic neighbor relation ANR opening.

And step 304, transmitting each frequency point to be tested to the edge UE through the Radio Resource Control (RRC) reconfiguration signaling.

Step 306, transmitting measurement indication information to each edge UE respectively; the measurement indication information is used for indicating the edge UE to measure the physical cell identification code PCI of each neighbor cell to be measured.

The measurement indication information comprises downlink control information DCI for indicating the measurement purpose and the measurement sequence of each round by adopting bits; the measurement purpose comprises the initial frequency point and the measurement number of the round, and the measurement sequence comprises the measurement of the frequency points from the initial frequency point to the completion of the measurement number; the initial frequency points are frequency points with preset sequencing numbers in all frequency points to be tested which are arranged in sequence.

Step 308, receiving a measurement report transmitted by the edge UE; the measurement report contains PCI measurement results; the PCI measurement includes a cell signal quality parameter.

Specifically, the edge UE measurement report reports parameters such as PCI measurement results and cell signal quality. In one embodiment, the cell signal quality parameter may comprise a reference signal received power, RSRP.

It should be noted that, the specific implementation process of steps 302 to 308 may refer to the descriptions related to steps 202 to 204, and will not be repeated here. The application indicates the measurement behavior of the UE based on the DCI (downlink control information) message issued by the base station, and specifically indicates the measurement purpose and the measurement sequence by bit. Therefore, the situation that part of frequency points cannot be measured and the measurement is repeated is avoided, the power consumption of the terminal is reduced, and the influence of an ANR function on the time delay of the terminal is reduced.

Step 310, if it is determined that no neighbor cell is added according to the neighbor cell relationship list, determining whether to enter global cell identity (CGI) measurement of the neighbor cell to be measured according to the cell signal quality parameter and the absolute threshold.

Specifically, after judging that no neighbor cell is added according to the neighbor cell relation list, the base station can judge whether to continue to measure the CGI of the neighbor cell, namely, whether to enter the global cell identification code CGI measurement stage according to the signal quality parameters such as RSRP in the PCI measurement result and the absolute threshold value.

Further, after PCI measurement is completed, the UE measurement report reports parameters such as PCI measurement results and cell signal quality, and after the base station judges that the neighbor cell is not added according to the neighbor cell relation list, the base station judges whether to continue to measure the CGI of the neighbor cell according to the signal quality parameters such as RSRP in the measurement results and the absolute threshold value, and if so, the base station issues CGI measurement configuration.

Step 312, if it is determined to enter the global cell identity CGI measurement, transmitting CGI measurement configuration information to the edge UE; the CGI measurement configuration information is used to instruct the edge UE to enter a discontinuous reception DRX sleep period in the global cell identity CGI measurement.

Specifically, when it is determined that the global cell identity CGI measurement is to be performed, CGI measurement configuration information is issued to the edge UE. The CGI measurement configuration information can be used for indicating the edge UE to enter the Discontinuous Reception (DRX) dormant period in the CGI measurement of the global cell identification code, so that the CGI reading success rate can be improved.

When the ANR function is started, the UE is scheduled through DCI indication, reasonable and efficient PCI and CGI measurement is performed, the CGI reading success rate is improved, and the problems that the UE cannot measure all frequency points to be measured due to the fact that the number of measurement frequency points is more and less and the CGI reading success rate is low can be solved.

In one embodiment, the CGI measurement configuration information may include a power save wake up signal;

the power saving wake-up signal is used to instruct the edge UE to turn off the DRX ON Duration timer in the following DRX cycle to stop physical downlink control channel PDCCH (Physical Downlink Control Channel ) listening.

Specifically, in the CGI measurement stage, the base station may issue a power saving wake-up signal to the edge UE, to instruct the edge UE not to start the DRX ON Duration timer in the subsequent DRX cycle, that is, not to wake up to receive the PDCCH, thereby providing a sufficient sleep period and improving the CGI reading success rate. Namely, the application proposes to control the UE not to start the DRX ON Duration timer in the DRX period through the energy-saving wake-up signal.

In some examples, during the CGI measurement phase, the base station issues a UE power saving wake-up signal before the start time of the DRX ON Duration timer of the UE, and the wake-up indication needs 1bit, and indicates that the UE does not start the DRX ON Duration timer in a subsequent DRX cycle by taking a value of "0".

Namely, the application utilizes the energy-saving wake-up signal to improve the CGI reading success rate; the terminal receives an indication of a power saving wake-up signal before the DRX ON Duration, as shown in fig. 4, when a terminal has data transmission in one DRX cycle, the power saving wake-up signal "wakes up" the terminal to detect the PDCCH during the DRX ON Duration; otherwise, when the terminal has no data transmission in one DRX cycle, the power saving wake-up signal does not "wake up" the terminal, which does not need to detect PDCCH during the DRX ON Duration.

The wake-up instruction needs 1bit, and the bit value is '0', so that the UE is instructed not to start the DRX ON Duration timer in the subsequent DRX period, namely, the PDCCH is not required to be wake-up to be received, and therefore the UE enters a DRX sleep period with sufficient time to perform CGI measurement, and the CGI reading success rate is improved.

Further, as shown in fig. 5, when configuring DRX, the terminal detects the PDCCH in the DRX ON Duration, and if the data scheduling is received during the DRX ON Duration, the terminal continuously detects the PDCCH based ON control of the DRX timer until the data transmission is completed; otherwise, if the terminal does not receive data scheduling during the DRX ON Duration, the terminal enters a DRX (discontinuous reception) sleep period to implement sleep and save energy, and the UE needs to use the DRX sleep period to complete CGI measurement of the neighbor cell to be measured.

In the measurement method, the ANR measurement can be divided into PCI measurement and CGI measurement stages, and different strategies are adopted; the application provides a method for guiding UE to measure sequence by using measurement indication DCI and guiding UE to enter a dormant state by using dormant indication DCI, and aims at different ANR measuring stages, thereby solving the problems that the frequency points to be measured cannot be measured completely and the CGI reading success rate is low.

Based on the application, the problem that the UE only can detect the front frequency division point in each round of measurement and can not finish the measurement of all the frequency points to be measured when issuing all the frequency points to be measured to the UE under the condition that a plurality of frequency points to be measured exist but the number of the edge UE is relatively small can be avoided. The application guides the dispatching UE to carry out high-efficiency and reasonable frequency point measurement through DCI, and avoids excessive signaling overhead caused when the base station issues RRC reconfiguration signaling for many times to guide the UE to measure. Furthermore, the application controls the initial frequency point number measured by the UE through DCI, and avoids a plurality of UEs to repeatedly measure the PCI and the CGI of a certain frequency point, thereby avoiding the repeated waste of resources and the increase of time delay, and reducing the measurement power consumption of the terminal. In addition, the application controls the UE not to start the DRX ON Duration timer in the DRX period through the energy-saving wake-up signal, namely, the PDCCH is not required to be wake-up to be received, thereby providing enough dormancy period and improving the CGI reading success rate.

It should be understood that, although the steps in the flowcharts of fig. 2 and 3 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2, 3 may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed sequentially, but may be performed alternately or alternately with at least a portion of the other steps or sub-steps of other steps.
