Technical field

This application relates to the field of communication technology, and in particular to a measurement configuration method and equipment.

Background technique

In a communication system, in order to ensure the service continuity and communication quality of the terminal equipment, the terminal equipment usually needs to perform cell measurement, thereby realizing cell reselection and cell handover. The types of cell measurement include intra-frequency measurement and inter-frequency/different system measurement.

When a terminal device initially accesses or performs inter-frequency/different system measurement in the process of radio resource control (radio resource control, RRC) connected state (RRC_connective), the terminal device needs to use the gap measurement method to perform cell measurement. The specific process includes : In the gap, the terminal device receives the reference signal of the neighboring cell, and measures the reference signal of the neighboring cell. After the measurement is completed, the terminal device sends a measurement report (measurement report) to the base station that manages the serving cell. Then the base station switches the terminal equipment to a cell with better signal quality according to the measurement report.

At present, before the terminal device performs cell measurement, the base station that manages the serving cell needs to perform measurement configuration and send the measurement configuration information to the terminal device. The measurement configuration information that the terminal device can receive can determine the location of each gap to perform neighbor cell measurements. Usually the gap length is 6 milliseconds (ms). Among them, the measurement configuration information includes: measurement gap repetition period (MGRP) (also known as gap period), measurement gap length (measurement gap length, MGL) (abbreviated as gap length), and the start of the measurement gap. Start position (gap offset). Optionally, the measurement configuration information may also include information such as a measurement report reporting strategy and a list of neighboring cells to be measured.

In order to improve the cell measurement efficiency, the terminal equipment in the gap should be able to receive the reference signals of all neighboring cells to be measured. However, the position of the gap is determined by the terminal equipment according to the timing of the serving cell, and the time domain position of each neighboring cell sending the reference signal is determined according to the timing of the corresponding neighboring cell. Therefore, the gap determined by the terminal device according to the measurement configuration information may not contain the time-domain positions of the reference signals of some neighboring cells to be measured. As a result, the terminal device cannot receive the reference signals of these neighboring cells to be measured, and thus cannot complete all the reference signals to be measured. Measurement of the cell.

Summary of the invention

This application provides a measurement configuration method and equipment, which are used to increase the probability that the measurement gap covers the reference signals of all neighboring cells to be measured during the cell measurement process of the terminal equipment, and improve the success rate and efficiency of the cell measurement of the terminal equipment.

In the first aspect, the embodiments of the present application provide a measurement configuration method, which can be applied to various scenarios in the communication system shown in FIG. 2 where inter-frequency/different-system measurement needs to be performed in a gap measurement mode. The method includes: a base station sends first measurement configuration information to the terminal device; wherein the first measurement configuration information is used to instruct the terminal device to adjust the value of the gap length used in cell measurement from G1 to G2, where , G2 is greater than G1. Exemplarily, the base station may, after determining that the cell measurement of the terminal device fails, or include the NR cell in the neighboring cells to be measured of the terminal device, or upon receiving an instruction, or within a time window, send the first Measurement configuration information.

In this method, after determining that the cell measurement of the terminal device fails, the base station instructs the terminal device to use a longer gap when subsequently performing cell measurement. In this way, in the subsequent cell measurement process, the probability that the terminal device receives the reference signals of all neighboring cells to be measured in the gap can be increased. Therefore, this method can improve the success rate and efficiency of the terminal device cell measurement.

In a possible design, the first measurement configuration information is also used to indicate that the starting position of the gap is adjusted from P1 to P2, where P2>P1.

Since the terminal device failed in the previous cell measurement, and even if the terminal device has received part of the reference signal to be measured in the previous gap position, the terminal device has already measured the part of the measurement reference signal. Through this design, the base station can migrate the gap position when reconfiguring the gap, and eliminate the gap position before adjustment, so that the terminal device can avoid occupying the original gap position for cell measurement and lead to service throughput of the terminal device. The rate drops.

In a possible design, before the base station sends the first measurement configuration information to the terminal device, the base station may determine G2 through the following two methods:

Method 1: The base station determines G2 according to the value T1 of the reference signal transmission period of the neighboring cell to be measured, where T1>G1;

Method 2: The base station determines G2 according to G1.

In the above method 1, the gap length reconfigured by the base station for the terminal device is adjusted based on the reference signal transmission period of the neighboring cell to be measured. Therefore, this method can improve the adjusted gap coverage of all to be measured The probability of the reference signal of the neighboring cell can increase the probability that the terminal device can receive the reference signal of all neighboring cells in the adjusted gap, thereby improving the success rate and efficiency of the cell measurement of the terminal device.

In the second method above, the base station may increase the length of the gap on the basis of the original gap length. Since the second embodiment is to determine G2 based on the reference signal transmission period of the neighboring cell, however, when the reference signal transmission period of the neighboring cell is large (for example, T1 is equal to 40, 80, or 160), the second embodiment is used to determine G2 The gap is too long, which further causes a large loss in the service throughput of the terminal device. Obviously, this method can increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby improving the success rate and efficiency of the terminal device cell measurement, and ensuring the service throughput rate of the terminal device.

In a possible design, when the base station uses method one to determine G2, G2 conforms to the formula: G2=T1+m, and m is an integer greater than or equal to zero. In order to prevent time jitter and improve the service throughput rate of the terminal equipment as much as possible, m=1.

In a possible design, when the base station uses method two to determine G2, G2 conforms to the formula: G2=k*(G1-1)+r, or conforms to the formula: G2=k*G1+r, where k Is an integer greater than 2, and r is an integer greater than or equal to 0. Exemplarily, k is equal to 2, 4, 8, 16, 32. In order to prevent time jitter and improve the service throughput rate of the terminal equipment as much as possible, r=1.

In a possible design, before the base station sends the first measurement configuration information to the terminal device, the base station uses the value T1 of the reference signal transmission period of the neighboring cell and the gap start position difference Value, determine G2, where T1>G1, and the start position difference of the gap is P2-P1.

Through this design, the base station can adjust the length of the gap on the basis of the reference signal transmission period of the neighboring cell to be measured, and eliminate the length and position of the gap before adjustment from the gap length and the starting position. Obviously, this design can increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby improving the success rate and efficiency of the terminal device cell measurement, and ensuring the service throughput rate of the terminal device.

In a possible design, when the base station determines G2 through the above design, G2 conforms to the formula: G2=T1-(P2-P1)+n, where n is an integer greater than or equal to zero. In order to prevent time jitter and improve the service throughput rate of the terminal equipment as much as possible, n=1. Exemplarily, when the value of P1 is 6, in order to prevent time jitter, there may be an overlap of 1 ms between the adjusted gap position and the gap position before adjustment, that is, P2-P1=5.

In one possible design, G2 can be divisible by 6.

In a possible design, the base station may determine that the cell measurement of the terminal device fails in the following manner:

Manner 1: The base station does not receive a measurement report from the terminal device within a set time period, and it is determined that the cell measurement of the terminal device fails.

Manner 2: The base station receives a measurement report from the terminal device, and when the base station determines that the measurement report does not include the measurement results of all the cells to be measured, it determines that the cell measurement of the terminal device fails.

Manner 3: The base station receives a measurement report from the terminal device, and when the base station determines that there are invalid measurement results of some cells to be measured in the measurement report, it determines that the terminal device cell measurement fails.

Manner 4: When the base station receives the notification message from the terminal device, it determines that the cell measurement of the terminal device fails.

In a possible design, in order to speed up the reporting time of the measurement report of the terminal device, so that the base station can perform cell handover or add SCG for the terminal device as soon as possible, the first measurement configuration information is also used to indicate measurement The reporting strategy of the report is periodic triggering, or a reporting strategy that prefers the arrival time first in periodic triggering or event triggering.

In a possible design, the first measurement configuration information is also used to instruct the terminal device to adjust the value of the gap period used in cell measurement from S1 to S2, where S2>S1.

Because the above method is used to adjust the length (and starting position) of the gap used by the terminal equipment for subsequent cell measurement, the adjusted gap can effectively increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby improving the cell measurement of the terminal equipment The success rate and efficiency. Therefore, in order to ensure the service throughput rate of the terminal device, the base station may further adjust the gap period used by the terminal device for subsequent cell measurement, that is, adjust the gap period from S1 to S2, where S2>S1. Exemplarily, S2 conforms to the formula S2=a*S1, where a is an integer greater than 2. When the G2 determined by the base station conforms to the formula G2=k*(G1-1)+r, or G2=k*G1+r, in order to ensure that the ratio of gap length to gap period before and after adjustment is small, the base station may The change multiple of the set period is the same as the change multiple of the gap length, that is, a=k.

In a possible design, after the base station sends the first measurement configuration information to the terminal device, it may also send second measurement configuration information to the terminal device; wherein the second measurement configuration information is used In the instruction: the terminal device stops performing cell measurement; or the second measurement configuration information is used to indicate at least one of the following:

The value of the gap length used when the terminal device performs cell measurement is restored to G1;

The value of the gap period used by the terminal device for cell measurement is adjusted from S3 to S4, where S4>S3. Exemplarily, S4 conforms to the formula: S4=b*S3, where b is an integer greater than 2.

Due to the above method, adjusting the length (and starting position) of the gap used by the terminal equipment for subsequent cell measurement can effectively increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby increasing the cell of the terminal equipment The success rate and efficiency of the measurement. In addition, since the gap length for the terminal device to perform cell measurement is increased, the service throughput rate of the terminal device may be affected. In summary, the base station may send the second measurement configuration information to the terminal device to compensate for the service throughput rate of the terminal device.

In the second aspect, the embodiments of the present application provide a measurement configuration method, which can be applied to various scenarios in the communication system shown in FIG. 2 where inter-frequency/different-system measurement needs to be performed in a gap measurement manner. The method includes: a terminal device receives first measurement configuration information sent by a base station, where the first measurement configuration information is used to instruct the terminal device to adjust a gap length value used in cell measurement from G1 to G2, where: G2 is greater than G1; the terminal device determines the location of the gap according to the first measurement configuration information, and performs cell measurement in the gap, where the length of the gap is G2.

Detailed ways

This application provides a measurement configuration method and device, which are used to increase the probability that the measurement gap covers the reference signals of all neighboring cells to be measured during the cell measurement process of the terminal device, and improve the efficiency of the cell measurement of the terminal device. Among them, the method and the device are based on the same technical concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Hereinafter, some terms in this application will be explained to facilitate the understanding of those skilled in the art.

1) Terminal equipment is a device that provides users with voice and/or data connectivity. The terminal equipment may also be called user equipment (UE), mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), and so on.

For example, the terminal device may be a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, some examples of terminal devices are: mobile phones (mobile phones), tablet computers, notebook computers, handheld computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented Augmented reality (AR) equipment, wireless terminals in industrial control, wireless terminals in self-driving (self-driving), wireless terminals in remote medical surgery, and smart grid (smart grid) The wireless terminal in the transportation safety (transportation safety), the wireless terminal in the smart city (smart city), the wireless terminal in the smart home (smart home), etc.

2) A base station is a device that connects terminal equipment to a wireless network in a communication system. As a node in a radio access network, the base station can also be referred to as a network device, and can also be referred to as a radio access network (RAN) node (or device).

At present, some examples of base stations are: gNB, evolved Node B (eNB), transmission reception point (TRP), radio network controller (RNC), node B (Node B) , NB), base station controller (BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), or baseband unit (baseband unit) , BBU) etc.

In addition, in a network structure, the base station may include a centralized unit (CU) node and a distributed unit (DU) node. This structure splits the protocol layer of the eNB in the long term evolution (LTE) system. Some of the protocol layer functions are placed under the centralized control of the CU, and some or all of the protocol layer functions are distributed in the DU. Centralized control of DU.

3) Measurement configuration information, which is sent by the base station to the terminal equipment, to enable the terminal equipment to perform cell measurement based on the measurement configuration information. Generally, the base station can send the measurement configuration information through RRC signaling. Wherein, the measurement configuration information may, but is not limited to, include at least one of the following measurement parameters: a measurement object, a list of neighbor cells to be measured, or gap configuration parameters (gap period, gap length, gap start position).

In the embodiment of the present application, after the base station sends the measurement configuration information to the terminal device once, the base station may further send the measurement configuration information again to instruct the base station to adjust the value of at least one of the above measurement parameters. In this way, the base station can flexibly reconfigure the measurement parameters.

Wherein, the base station instructs the base station to adjust the value of any measurement parameter through the measurement configuration information, which may include but is not limited to the following forms:

The measurement configuration information includes the adjusted value of the measurement parameter.

The measurement configuration information includes the adjustment value of the measurement parameter, and the adjustment value may be the difference between the adjusted value of the measurement parameter and the value before the adjustment.

The measurement configuration information includes an adjustment instruction of the measurement parameter. The terminal device may determine the adjusted value of the measurement parameter according to the adjustment instruction of the measurement parameter in a manner agreed with the base station.

4) The measurement report is obtained by the terminal equipment after cell measurement and reported to the base station.

In the case that the terminal device receives the reference signal of at least one neighboring cell to be measured in the gap, the measurement report may include the measurement result of the terminal device on the at least one neighboring cell to be measured, or the measurement results of all the neighboring cells to be measured. (Wherein, the measurement result of the neighboring cell to be measured for which the terminal device does not receive the reference signal is null or zero, and the measurement result of the at least one neighboring cell to be measured is the actual measurement value).

In the case that the terminal device does not receive the reference signal of the neighbor cell to be measured in the gap, the terminal device may not report the measurement report, or the reported measurement report is empty, or each neighbor cell to be measured in the reported measurement report The measurement result of is empty or zero.

Exemplarily, the measurement result of each neighboring cell to be measured may be the signal quality parameter of the neighboring cell to be measured. Optionally, the signal quality parameter may include one or more of the following parameters:

Reference signal received power (RSRP), signal to interference plus noise ratio (SINR), received signal strength indication (RSSI), reference signal received quality (reference signal received quality) , RSRQ).

5) "and/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B alone exists. Happening. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

It should be noted that the multiple involved in this application refers to two or more.

In addition, it should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing description, and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating Or imply the order.

The following describes the traditional gap measurement method first.

The types of cell measurement include: same frequency measurement, different frequency/different system measurement. Among them, the same frequency measurement means that the neighboring cell to be measured and the serving cell of the terminal device are in the same carrier frequency. Inter-frequency/system measurement means that the neighboring cell to be measured and the serving cell of the terminal device are not on the same carrier frequency.

We know that terminal equipment receives and sends signals through radio frequency channels, and a set of radio frequency channels generally work on a carrier frequency.

During the initial access of the terminal equipment or in the RRC connection state, if multiple sets of radio frequency channels are set in the terminal equipment, the terminal equipment can use one of the radio frequency channels to adjust to the carrier frequency of the serving cell to receive the serving cell. At the same time, the terminal equipment can also adjust other radio frequency channels to the carrier frequency of the neighboring cell to receive the reference signal of the neighboring cell. In this way, the terminal device can perform cell measurement without suspending service transmission.

However, when only one set of radio frequency channels are set up inside the terminal equipment, referring to Figure 1A, the terminal equipment cannot perform service transmission and cell measurement at the same time, because the terminal equipment needs to adjust the radio frequency channel to the carrier frequency of the serving cell. To receive signals from the serving cell and send signals to the serving cell; in the gap, the terminal device stops interacting with the serving cell, and adjusts the radio frequency path to the carrier frequency of the neighboring cell to receive the reference signal of the neighboring cell.

The base station sends measurement configuration information to the terminal device to configure the terminal device for gap measurement. In the gap configuration parameters in the measurement configuration information, the value of the gap period (MGRP) can be 40ms, 80ms, etc.; the maximum value of the gap length (MGL) is 6ms; the value of the start position of the gap (gapoffset) The range can be 0-39, or 0-79, etc. The terminal device can calculate the time domain position of the gap according to the above gap configuration parameters, as shown in Figure 1B. Specifically, the terminal device can calculate the time domain position of the gap with reference to the following formula:

T=MGRP/10;

SFN mod T=FLOOR(gapoffset/10);

subframe=gapoffset mod 10;

Wherein, SFN is the system frame number of the serving cell of the terminal device, and subframe is the subframe in the system frame of the SFN.

In order to ensure the cell measurement efficiency of the terminal equipment and improve the success rate of the cell measurement of the terminal equipment, the terminal equipment in the gap configured for the terminal equipment in the base station should be able to receive the reference signals of all neighboring cells to be measured, so that the terminal equipment can achieve Measurement of all neighboring cells to be measured.

However, the time domain position of the gap is determined by the terminal device according to the timing of the serving cell, and the time domain position of the reference signal of each neighboring cell is determined according to the timing of the corresponding neighboring cell.

For example, fourth generation long term evolution (The 4 ^th Generation, 4G) communication technology (long term evolution, LTE) cell reference signal - reference signal cell (cell reference signal, CRS) are uniformly distributed in each sub-frame of.

Also for example, refer to Figure 1C, the fifth generation (The 5 ^th Generation, 5G) new air interface communication technologies (new radio, NR) cell reference signal - block synchronization signal (synchronization signal block, SSB) is sent in the period Yes, and multiple SSBs can be sent in a period, but the multiple SSBs are concentrated in a certain time window in the period to form an SSB burst. Among them, the SSB period can be 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms, etc., and the SSB period of different NR cells can also be different. Exemplarily, assuming that the SSB period is 20ms, the SSB burst can be transmitted in the first or second 5ms.

Therefore, the time-domain position of the gap determined by the terminal device according to the timing of the serving cell and the received measurement configuration information may not include the time-domain position of the reference signal of some neighboring cells to be measured, as shown by the dashed box in Figure 1D gap, which will cause the terminal device to fail to receive the reference signals of the neighboring cells to be measured in the gap, and thus fail to complete the measurement of all the cells to be measured, and cause the cell measurement of the terminal device to fail.

In order to solve the above problems, this application provides a measurement configuration method and equipment. In the solution provided by the embodiment of the present application, the base station may instruct the terminal device to use a longer gap when subsequently performing cell measurement. In this way, in the subsequent cell measurement process, the probability that the terminal device receives the reference signals of all neighboring cells to be measured in the gap can be increased. Therefore, this method can improve the success rate and efficiency of the terminal device cell measurement.

The embodiments of the present application will be described in detail below in conjunction with the drawings.

FIG. 2 shows the architecture of a possible communication system to which the measurement configuration method provided by the embodiment of the present application is applicable. Referring to FIG. 2, the communication system includes: a base station 201 (a base station 201a, a base station 201b, and a base station 201c in the figure), and a terminal device 202.

The base station 201 is responsible for providing wireless access-related services for the terminal device 202, realizing wireless physical layer functions, resource scheduling and wireless resource management, quality of service (QoS) management, wireless access control, and mobile The function of sexual management (such as cell reselection and handover).

Each base station 201 is responsible for managing at least one cell. As shown in the figure, base station 201a is responsible for managing cell A, base station 201b is responsible for managing cell B, and base station 201c is responsible for managing cell C and cell D.

In this communication system, each cell uses a corresponding carrier frequency to provide access services for terminal equipment. It should be noted that the frequency points used by different cells may be the same or different. In addition, this application does not limit the communication technology used by each cell, and the communication technology used by different cells may be the same or different. Exemplarily, cell A, cell B, cell C, and cell D are all LTE cells using 4G communication technology; or cell A, cell B, cell C, and cell D are all NR cells using 5G communication technology; or cell A , Cell B, Cell C and Cell D, some of the cells are LTE cells, and some of the cells are NR cells.

The terminal device 202 is a device that accesses the network through a cell managed by the base station 201.

The base station 201 and the terminal device 202 are connected through a Uu interface, so as to realize the communication between the terminal device 202 and the base station 201.

In addition, the architecture shown in Figure 2 can be applied to a variety of communication scenarios, for example, the fifth generation (The 5th Generation, 5G) communication system, the future sixth generation communication system and other evolving communication systems, long-term evolution (Long Term Evolution, LTE) communication system, vehicle to everything (V2X), long-term evolution-Internet of Vehicles (LTE-vehicle, LTE-V), vehicle to vehicle (V2V), Internet of Vehicles, machine Communication (Machine Type Communications, MTC), Internet of Things (IoT), Long Term Evolution-Machine to Machine (LTE-Machine to Machine, LTE-M), Machine to Machine (M2M) and other communication scenarios in.

The measurement configuration method provided in the embodiments of the present application is applicable to various scenarios in the communication system shown in FIG. 2 where inter-frequency/inter-system measurement needs to be performed through gap measurement methods, for example, LTE measurement scenarios in 4G communication technology, and The following scenarios supporting Dual Connectivity (DC) technology in 5G communication technology: EN-DC (EUTRA-NR Dual Connectivity) scenarios, NE-DC (NR-EUTRA Dual Connectivity), NR-DC, and non-DC scenarios .

Assuming that the terminal device 202 accesses the cell A managed by the base station 201a (cell A is a serving cell), and the cell B, the cell C, and the cell D are neighboring cells determined by the base station 201a for the terminal device 202.

For example, in LTE measurement scenarios and non-DC scenarios, the base station 201a sends measurement configuration information to the terminal device 202, where the measurement configuration information includes gap configuration parameters and a list of neighboring cells to be measured (including cell B, cell C, and cell D); The terminal device 202 determines the time domain position of the gap according to the measurement configuration information, and performs cell measurement in the gap, and reports the measurement report to the base station 201a after the measurement is completed; the base station 201a switches the terminal device according to the signal quality parameters of each cell in the measurement report To the cell with better signal quality.

For another example, in each scenario supporting dual connectivity technology, cell A is the primary cell (primary cell, PCell) of the terminal device 202, and the base station 201a is the primary base station of the terminal device 202. The base station 201a sends measurement configuration information to the terminal device 202, where the measurement configuration information includes gap configuration parameters and a list of neighboring cells to be measured (including cell B, cell C, and cell D); the terminal device 202 determines the time domain of the gap according to the measurement configuration information Position, and perform cell measurement in the gap, and report a measurement report to the base station 201a after the measurement is completed; the base station 201a configures a secondary cell (SCell) for the terminal device 202 according to the signal quality parameters of each cell in the measurement report, so as to achieve Add a secondary cell group (SCG) to the terminal device 202.

In order to improve the success rate and efficiency of the cell measurement of the terminal device, an embodiment of the present application provides a measurement configuration method. Among them, the method can be applied to various scenarios in the communication system shown in FIG. 2 where inter-frequency/different-system measurement needs to be performed in a gap measurement mode. The base station instructs the terminal device to use a longer gap during subsequent cell measurement through the measurement configuration information, that is, instructs the gap length value to be adjusted from G1 to G2, G2>G1. In this way, in the subsequent cell measurement process, the probability that the terminal device receives the reference signals of all neighboring cells to be measured in the gap can be increased. Therefore, this method can improve the success rate and efficiency of the terminal device cell measurement. Exemplarily, the base station may, after determining that the terminal device cell measurement fails, or determine that the neighboring cells to be measured of the terminal device includes an NR cell, or upon receiving an instruction, or sending the terminal device within a time window The first measurement configuration information.

The measurement configuration method provided in the embodiment of the present application will be described below in conjunction with the flowchart shown in FIG. 3. It should be noted that the method flowchart shown in FIG. 3 does not limit the measurement configuration method provided in this application, and the measurement configuration method provided in this application may include more or fewer steps than the method shown in FIG. 3. In addition, the various values involved in the embodiments of the present application are taken on the basis that the unit of measurement parameters such as the length of the gap and the length of the gap period is ms.

S301: The base station sends first measurement configuration information to a terminal device, where the first measurement configuration information is used to instruct the terminal device to use a gap length value of G1 when performing cell measurement. The terminal device receives the first measurement configuration information from the base station.

Exemplarily, the first measurement configuration information may be traditional measurement configuration information, which may include gap configuration parameters (gap period, gap length, and gap start position), and may also include a list of neighboring cells to be measured and a measurement report. Escalation strategy and other information. For example, the first measurement configuration information may be measGapConfig signaling or measConfig signaling.

The length of the initial gap configured by the base station for the terminal device through the first measurement configuration information may be, but is not limited to, 6 ms. In the following description and examples of the embodiments of the present application, only G1=6 is taken as an example for description.

S302: The terminal device determines the location of the gap used for this cell measurement according to the first measurement configuration information, as shown in FIG. 1B, and performs cell measurement in the determined gap. The gap length takes the value G1, the gap period takes the value S1, and the start position of the gap takes the value P1.

In the embodiment of the present application, the terminal device performing cell measurement in the gap includes: the terminal device receives the reference signal of the neighbor cell to be measured in the gap, and determines the measurement result of the neighbor cell to be measured.

It should be noted that the time domain positions of the reference signals of all neighboring cells to be measured may not be covered in the gap, for example, as shown in Figure 1D. Therefore, in the gap, the terminal device may only receive a part of the reference signal of the cell to be measured. Signal, or the reference signal of all the cells to be measured is not received, and the cell measurement of the terminal device fails at this time.

In the case that the cell measurement of the terminal device fails, the terminal device may, but is not limited to, notify the base station in the following manner:

Manner 1: The terminal device may not send a measurement report to the base station according to the reporting strategy of the measurement report, or according to an agreement or an agreement with the base station.

Manner 2: The terminal device may send a measurement report carrying measurement results of some neighboring cells to be measured to the base station.

Manner 3: The terminal device may send a measurement report carrying the measurement results of all neighboring cells to be measured to the base station, and the measurement results of the neighboring cells to be measured that are not measured by the terminal device in the measurement report are invalid. Exemplarily, the measurement result of the cell to be measured that is not measured by the terminal device may be empty, zero, or an indicator used to indicate that the measurement result is invalid.

Manner 4: The terminal device may send a notification message to the terminal device, and the notification message is used to notify the base station that the terminal device cell measurement fails.

S303: When the terminal device notifies the base station that the cell measurement fails in the above manner two or three, the terminal device sends a first measurement report to the base station. The base station receives the first measurement report from the terminal device. As shown in the figure, this step is optional.

Wherein, when the terminal device adopts the above method two, the first measurement report contains the measurement results of some neighboring cells to be measured; when the terminal device adopts the above method three, the first measurement report includes all The measurement result of the cell to be measured, and only the measurement result of the adjacent cell to be measured measured by the terminal device is valid.

S304: The base station determines that the cell measurement of the terminal device fails.

Corresponding to the manner in which the terminal device notifies the base station of the cell measurement failure in S302, the base station may also determine that the terminal device cell measurement fails in the following manner:

Manner 2: The base station receives a first measurement report from the terminal device, and when the base station determines that the first measurement report does not include measurement results of all cells to be measured, it determines that the terminal device cell measurement fails.

Manner 3: The base station receives a first measurement report from the terminal device, and when the base station determines that there are invalid measurement results of some cells to be measured in the first measurement report, it determines that the terminal device cell measurement fails.

S304a: The base station adjusts the gap length used by the terminal device for subsequent cell measurement, and determines the gap length used by the terminal device for subsequent cell measurement as G2, where G2 is greater than G1.

Optionally, in this step, the base station may also adjust the starting position of the gap used by the terminal device when performing subsequent cell measurements, and determine the starting position of the gap used by the terminal device when performing subsequent cell measurements. Value P2, where P2 is greater than P1. Since the terminal device failed in the previous cell measurement, and even if the terminal device has received part of the reference signal to be measured in the previous gap position, the terminal device has already measured the part of the measurement reference signal. Therefore, when the base station reconfigures the gap, the position of the gap can be migrated, and the gap position part before adjustment is removed. In this way, the terminal device can avoid occupying the original gap position part for cell measurement, resulting in a decrease in the service throughput of the terminal device. After the terminal device uses the adjusted gap to perform cell measurement, the measurement result of the neighboring cell to be measured this time and the measurement result of the neighboring cell to be measured obtained in the previous cell measurement can be included in the measurement report and reported to all Mentioned base station.

Exemplarily, when the gap length before adjustment takes the value G1=6, P2 may conform to the formula: P2-P1=6.

Exemplarily, in order to prevent time jitter, there may be an overlap of 1 ms between the adjusted gap position and the gap position before adjustment, that is, P2-P1=5.

In S304a, according to different ways of determining G2 by the base station, the base station may, but is not limited to, determine G2 through the following four implementation manners.

The first implementation manner: the base station obtains G2, which is greater than the value of G1, from the stored gap length values.

The second implementation manner: The base station determines G2 according to the value T1 of the reference signal transmission period of the neighboring cell to be measured, where T1>G1.

Optionally, in this embodiment, G2 determined by the base station may conform to the following formula: G2=T1+m, where m is an integer greater than or equal to zero. Exemplarily, the value of m may be 0, 1, 2, and so on. In order to prevent time jitter, the value of m can be an integer greater than 0.

Example 1: When G1=6, T1=20, m=1, and the value of the gap period S1=40, the comparison before and after gap length adjustment is shown in Fig. 4A.

Example 2: Based on the gap length adjustment solution shown in Example 1, the base station can adjust the value of the gap start position from 0 to 5, and the gap length and the comparison before and after the start position adjustment are shown in Fig. 4B.

In the second implementation manner, the gap length reconfigured by the base station for the terminal device is adjusted based on the reference signal transmission period of the neighboring cell to be measured. Therefore, the adjusted gap coverage can be improved through this implementation manner. The probability of the reference signal of all neighboring cells to be measured can increase the probability that the terminal device can receive the reference signal of all neighboring cells in the adjusted gap, thereby improving the success rate and efficiency of the cell measurement of the terminal device, as shown in Figure 4A and Shown in 4B.

The third implementation manner: the base station determines G2 according to the value G1 of the previously configured gap length.

Optionally, in this embodiment, G2 determined by the base station may conform to any of the following formulas: G2=k*(G1-1)+r; G2=k*G1+r. Among them, k is an integer greater than 2, and r is an integer greater than or equal to 0. Exemplarily, the value of k is 2, 4, 8, 16, 32, and so on. The value of r can be 0, 1, 2, etc. In order to prevent time jitter, the value of m can be an integer greater than 0.

Example 3: When G1=6, k=2, r=1, and the value of the gap period S1=40, the comparison before and after gap length adjustment is shown in Fig. 4C.

Example 4: On the basis of the gap length adjustment solution shown in Example 3, the base station can adjust the starting position of the gap from 0 to 5. The comparison of the gap length and the starting position before and after adjustment is shown in Figure 4D .

In the third implementation manner, the base station may increase the length of the gap on the basis of the original gap length. Since the second embodiment is to determine G2 based on the reference signal transmission period of the neighboring cell, however, when the reference signal transmission period of the neighboring cell is large (for example, T1 is equal to 40, 80, or 160), the second embodiment is used to determine G2 The gap is too long, which further causes a large loss in the service throughput of the terminal device. Obviously, this embodiment can increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby improving the success rate and efficiency of the terminal device cell measurement, as shown in Figures 4C and 4D, and ensuring the terminal device’s Business throughput rate.

Fourth implementation manner: when the starting position of the gap used by the base station for subsequent cell measurement of the terminal device is adjusted from P1 to P2, the base station may be based on the reference signal transmission period of the neighboring cell The value of T1, and the gap's starting position difference, determine G2, where T1>G1, and the gap's starting position difference is P2-P1.

Optionally, in this embodiment, G2 determined by the base station may conform to the formula: G2=T1-(P2-P1)+n, where n is an integer greater than or equal to zero. Exemplarily, the value of n may be 0, 1, 2, and so on. In order to prevent time jitter, the value of m can be an integer greater than 0.

Example 5: When G1=6, T1=20, n=1, P2-P1=5, and the value of the gap period S1=40, the base station can adjust the start position of the gap from 0 to 5 , The gap length and the comparison of the starting position before and after adjustment are shown in Figure 4E.

In the fourth implementation manner, the base station may adjust the length of the gap on the basis of the reference signal transmission period of the neighboring cell to be measured, and eliminate the length and position of the gap before adjustment from the gap length and the starting position. Obviously, this embodiment can increase the probability that the adjusted gap covers the reference signals of all neighboring cells to be measured, thereby improving the success rate and efficiency of the terminal device cell measurement, and ensuring the service throughput rate of the terminal device, as shown in Figure 4E Show.

It should also be noted that, in any of the above implementation manners, G2 determined by the base station may be divisible by 6. Since in the LTE system, the gap length used by the terminal equipment for cell measurement is 6 ms, in the embodiment of the present application, when adjusting the gap length, the gap length is set to a multiple of 6, so that the multiplexing of LTE cell measurement can be realized.

Through the above four implementation manners, by adjusting the length (and starting position) of the gap used by the terminal device for subsequent cell measurement by the above method, the probability that the adjusted gap covers all the reference signals of the neighboring cells to be measured can be effectively improved. , Thereby improving the success rate and efficiency of terminal equipment cell measurement. Therefore, in order to ensure the service throughput rate of the terminal device, the base station may further adjust the gap period used by the terminal device for subsequent cell measurement, that is, adjust the gap period from S1 to S2, where S2>S1. Exemplarily, S2 conforms to the formula S2=a*S1, where a is an integer greater than 2. When the base station determines the gap length G2 in the third implementation manner, in order to ensure that the ratio of the gap length to the gap period before and after adjustment is small, the base station may set the period change multiple to be the same as the gap length change multiple, that is, a=k.

In addition, in order to speed up the reporting time of the measurement report of the terminal device, so that the base station can perform cell handover or add SCG for the terminal device as soon as possible, the base station may further adjust the reporting strategy of the measurement report as: periodic trigger, or It is a reporting strategy that preferentially arrives first in period triggering or event triggering.

S305: The base station sends second measurement configuration information to the terminal device. Wherein, the first measurement configuration information is used to instruct the terminal device to adjust the value of the gap length used in cell measurement from G1 to G2, where G2 is greater than G1. The terminal device receives the second measurement configuration information from the base station.

Wherein, the second measurement configuration information may, but is not limited to, instruct the length of the gap to be adjusted from G1 to G2 in the following manner:

Manner 1: The second measurement configuration information includes the gap length value G2.

Manner 2: The second measurement configuration information includes an adjustment value of the gap length, and the adjustment value is the difference between G2 and G1. In this way, after receiving the second measurement configuration information from the base station, the terminal device can determine G2 according to the adjustment value and the gap length G1 before adjustment.

Manner 3: The second measurement configuration information includes an adjustment instruction for the gap length, where the adjustment instruction is used to indicate G2 or a calculation method for calculating G2. In this way, after receiving the second measurement configuration information from the base station, the terminal device can determine or calculate G2 according to the adjustment instruction.

When the base station further determines in S304a that the value of the starting position of the gap is adjusted to P2, correspondingly, the second measurement configuration information is also used to indicate that the value of the starting position of the gap is adjusted from P1 to P2.

Similar to the second measurement configuration information indicating that the value of the gap length is adjusted from G1 to G2, the second measurement configuration information may also, but not limited to, indicate that the starting position of the gap is adjusted from P1 to P2 in the following manner :

Manner 1: The second measurement configuration information includes the starting position of the gap as P2.

Manner 2: The second measurement configuration information includes an adjustment value of the starting position of the gap, and the adjustment value is the difference between P2 and P1. In this way, after the terminal device receives the second measurement configuration information from the base station, it can determine P2 according to the adjustment value and the starting position of the gap before the adjustment takes the value P1.

Manner 3: The second measurement configuration information includes an adjustment instruction for the starting position of the gap, where the adjustment instruction is used to indicate P2 or a calculation method for calculating P2. In this way, after receiving the second measurement configuration information from the base station, the terminal device can determine or calculate P2 according to the adjustment instruction.

When the base station further determines in S304a that the value of the gap period is adjusted to S2, correspondingly, the second measurement configuration information is further used to instruct the value of the gap period to be adjusted from S1 to S2. The second measurement configuration information can also, but is not limited to, instruct the gap period value to be adjusted from S1 to S2 in the following manner:

Manner 1: The second measurement configuration information includes the gap period value S2.

Manner 2: The second measurement configuration information includes an adjustment value of the gap period, and the adjustment value is the difference between S2 and S1, or the quotient of S2 divided by S1. In this way, after receiving the second measurement configuration information from the base station, the terminal device can determine S2 according to the adjustment value and the gap period value S1 before adjustment.

Manner 3: The second measurement configuration information includes an adjustment instruction of the gap period, where the adjustment instruction is used to indicate S2 or a calculation method for calculating S2. In this way, after receiving the second measurement configuration information from the base station, the terminal device can determine or calculate S2 according to the adjustment instruction.

When the base station further determines to adjust the reporting strategy of the measurement report in S304, correspondingly, the second measurement configuration information is also used to indicate that the reporting strategy of the measurement report is periodic triggering, or is preferred in periodic triggering or event triggering. Reporting strategy with first arrival time.

Optionally, the second measurement configuration information may be multiple pieces of information. For example, the second measurement configuration information may include 4 signaling, which are respectively used to indicate the gap length, the gap period, the start position of the gap, and the measurement Reporting of results and adjustment of measurements. For another example, the second measurement configuration information may include two signalings, signaling 1 is used to indicate the adjustment of the gap length, gap period, and the start position of the gap, and signaling 2 is used to indicate the adjustment of the measurement result report measurement.

Exemplarily, the signaling 1 may be measGapConfig signaling, and the second measurement configuration information carrying the signaling may be MeasConfig signaling. For example, the description of the second measurement configuration information is described as follows:

Among them, in the above description, gapOffset is the starting position of the gap, mgl is the gap length, and mgrp is the gap period. A value X is added to the value of mgl, and the specific value of X is P2 in the embodiment of this application.

Exemplarily, signaling 2 may be ReportConfigInterRAT, and its signaling is described as follows:

S306: The terminal device determines the location of the gap used for the next cell measurement according to the second measurement configuration information, and performs cell measurement within the determined gap, where the length of the gap is G2. For the position of the gap determined by the terminal device, reference may be made to the adjusted gap position shown in FIGS. 4A-4E.

Wherein, when the second measurement configuration information only indicates to adjust the gap length, the terminal device may indicate the gap start position and gap period configured by the base station during the last cell measurement, and the second measurement configuration information indicates The gap length G2 determines the position of the gap.

When the second measurement configuration information also instructs to adjust any other gap configuration parameter (for example, the start position of the gap or the gap period), the terminal device can be based on a configuration parameter that was not adjusted during the last cell measurement , And the gap length G2 indicated by the second measurement configuration information and the value of another gap configuration parameter to determine the position of the gap.

When the second measurement configuration information also instructs to adjust all other gap configuration parameters (including the start position of the gap and the gap period), then the terminal device can be based on the value of each gap configuration parameter indicated by the second measurement configuration information. Take a value to determine the location of the gap.

In this step, the process of the terminal device performing cell measurement in the gap is the same as that of S302. Therefore, the process of performing cell measurement by the terminal device can refer to the above description of S302, which will not be repeated here.

In addition, due to various reasons, this cell measurement may succeed or fail. When the terminal equipment cell measurement succeeds, the terminal equipment sends a second measurement report to the base station through S307; when the terminal equipment cell measurement fails, the terminal equipment can also pass the 4 steps described in S302. Ways to notify the base station that the current cell measurement failed.

S307: The terminal device sends a second measurement report to the base station. The base station receives the second measurement report from the terminal device. As shown in the figure, this step is optional.

When the second measurement configuration information is also used to indicate the reporting strategy of the measurement report, the terminal device reports the second measurement report according to the reporting strategy.

S308: The base station determines that the current cell measurement of the terminal device is successful according to the second measurement report.

Optionally, the base station may also determine that the terminal device has failed the current cell measurement in the same manner as in S304.

S309: The base station may send third measurement configuration information to the terminal device after S305 or after S308. The base station of the terminal device receives the third measurement configuration information.

In an implementation manner, the third measurement configuration information is used to indicate that the terminal device stops performing cell measurement. Optionally, the third measurement configuration information may specifically instruct the terminal device to stop performing cell measurement within a set time period; or the terminal device may, after receiving the third measurement configuration information, set time Stop cell measurement within the segment.

In another implementation manner, the third measurement configuration information is used to indicate at least one of the following:

The value of the gap period used by the terminal device for cell measurement is adjusted from S3 to S4, where S4>S3. Exemplarily, S4 conforms to the formula: S4=b*S3, where b is an integer greater than 2. Wherein, if the value of the gap period used when the terminal device is instructed to perform cell measurement again in the second measurement configuration information is adjusted to S2, then S3=S2, otherwise S3=S1.

As can be seen from the above description, since the second measurement configuration information sent in S305 indicates that the gap length used by the terminal device to perform cell measurement again is adjusted from G1 to G2, therefore, the terminal device successfully performs cell measurement through S306 In addition, since the gap length for cell measurement by the terminal device is increased, the service throughput rate of the terminal device may be affected. In summary, through any of the above implementation manners, the service throughput rate of the terminal device after S307 can be guaranteed or improved.

S310: In a case where the third measurement configuration information is the foregoing first implementation manner, the terminal device no longer performs cell measurement. In the case where the third measurement configuration information is the second implementation manner, the terminal device again determines the cell measurement to be used for the next cell measurement according to the gap length and/or gap period indicated by the third measurement configuration information. The position of the gap, and the cell measurement is performed within the determined gap.

In this step, the process of the terminal device performing cell measurement in the determined gap is the same as that of S302. Therefore, the process of performing cell measurement by the terminal device can refer to the above description of S302, which will not be repeated here.

Of course, after the terminal device performs cell measurement, it can also notify the base station of the measurement result of the neighboring cell to be measured by the terminal device.

It should also be noted that in this embodiment of the application, the base station sends various measurement configuration information to the terminal device, and the terminal device sends a measurement report or notification message to the base station, both of which can be implemented through RRC signaling. , This application does not limit this.

The embodiment of the present application provides a measurement configuration method. In this method, after determining that the cell measurement of the terminal device fails, the base station instructs the terminal device to use a longer gap when subsequently performing cell measurement. In this way, in the subsequent cell measurement process, the probability that the terminal device receives the reference signals of all neighboring cells to be measured in the gap can be increased. Therefore, this method can improve the success rate and efficiency of the terminal device cell measurement.
