Description

Measurement configuration method and equipment
Technical Field
The present application relates to the field of communications technologies, and in particular, to a measurement configuration method and device.
Background
In a communication system, in order to ensure service continuity and communication quality of a terminal device, the terminal device generally needs to perform cell measurement, so as to implement cell reselection (reselection) and cell handover (handover). The types of cell measurement include common-frequency measurement and different-frequency/different-system measurement.
When a terminal device initially accesses or performs inter-frequency/inter-system measurement in a Radio Resource Control (RRC) connected state (RRC _ connected), the terminal device generally needs to perform cell measurement by using a gap measurement method, which specifically includes: and the terminal equipment receives the reference signals of the adjacent cells in the gap and measures the reference signals of the adjacent cells. After the measurement is completed, the terminal device sends a measurement report (measurement report) to the base station managing the serving cell. And then the base station switches the terminal equipment to a cell with better signal quality according to the measurement report.
Currently, before performing cell measurement, a terminal device needs to perform measurement configuration by a base station managing a serving cell and send measurement configuration information to the terminal device. The terminal device can determine the position of each gap according to the received measurement configuration information so as to measure the adjacent cells. The gap length is typically 6 milliseconds (ms). Wherein, the measurement configuration information comprises: the measurement of the gap repetition period (MGRP) (also called gap period), the measurement of the gap length (MGL) (simply called gap length), and the measurement of the gap offset (gap offset). Optionally, the measurement configuration information may further include information such as a reporting policy of a measurement report and a to-be-measured neighbor cell list.
In order to improve the cell measurement efficiency, the terminal device should be able to receive the reference signals of all the neighboring cells to be measured within the gap. However, the position of the gap is determined by the terminal device according to the timing of the serving cell, and the time domain position of each neighbor cell transmitting the reference signal is determined according to the timing of the corresponding neighbor cell. Therefore, the gap determined by the terminal device according to the measurement configuration information may not include the time domain positions of the reference signals of some neighboring cells to be measured, so that the terminal device cannot receive the reference signals of the neighboring cells to be measured, and further cannot complete measurement of all the cells to be measured.
Disclosure of Invention
The application provides a measurement configuration method and equipment, which are used for improving the probability that a measurement gap covers all reference signals of adjacent cells to be measured in the process of cell measurement of terminal equipment and improving the success rate and efficiency of cell measurement of the terminal equipment.
In a first aspect, an embodiment of the present application provides a measurement configuration method, which may be applied in various scenarios in which inter-frequency/inter-system measurement needs to be performed in a gap measurement manner in the communication system shown in fig. 2. The method comprises the following steps: a base station sends first measurement configuration information to a terminal device, wherein the first measurement configuration information is used for notifying that M is contained in a gap periodiA gap, M used for the terminal equipment to measure the celliIs an integer greater than 1.
By the method, the base station informs the terminal equipment of using a plurality of gaps to measure the cell subsequently in the same gap period after determining that the cell measurement of the terminal equipment fails. Therefore, in the subsequent cell measurement process, the probability that the terminal equipment receives the reference signals of the adjacent cells to be measured in a plurality of gaps of one gap period can be improved, and therefore, the method can improve the success rate and the efficiency of the cell measurement of the terminal equipment.
In one possible design, the M is included in the first measurement configuration informationiThe offset of each of the individual gaps; or the first measurement configuration information includes the MiOffset f of the first of the individual gapi,a. Through the design, the terminal equipment can accurately determine the M according to the offset of the gap in the first measurement configuration informationiThe position of each gap.
In one possible design, the MiThe formula may be followed:
Figure BDA0002391851490000021
t1 is a reference signal transmission period of the neighboring cell to be measured, where r is a positive number less than or equal to L, and L is a gap length configured for the terminal device before the base station. For example, when the gap length L that the base station has not configured by the terminal device before is 6ms, the gap length L may be set to 5 ms.
By this design, since M is saidiEach gap can cover the time domain position of the reference signal of all the neighbor cells to be measured, and the terminal equipment can continuously pass through the M within one gap periodiThe individual gap continuously performs cell measurements. Therefore, the method can ensure that the terminal equipment receives the reference signals of all the adjacent cells to be measured in the gap period, thereby ensuring that the terminal equipment can successfully complete cell measurement as soon as possible.
In one possible design, the MiAccording to the formula:
Figure BDA0002391851490000022
and said M isiOffset f of the first of the individual gapi,aAccording to the formula: f. ofi,a=fi-1,b+ r; wherein, T1 is the reference signal transmission period of the adjacent cell to be measured, Mi-1The number of gap contained in the gap period configured for the terminal equipment by the base station last time, fi-1,bAnd the offset of the last gap in the gap period configured for the terminal equipment by the base station last time, wherein r is a positive number smaller than or equal to L, and L is the gap length configured for the terminal equipment by the base station. As with the above design, the r may be set to 5 ms.
Since the terminal device has already performed cell measurement at the last gap position and cell measurement fails (measurement results of all neighboring cells to be measured are not obtained), the gap position is removed, and the terminal device can still perform cell measurement at the next gap period in the next cell measurement processiAnd receiving the reference signals of other adjacent cells to be measured in the gap so as to obtain the measurement results of the other cells to be measured. Through the design, the terminal equipment and the base station can combine the measurement result obtained by the last cell measurement and the measurement result obtained by the current cell measurement to obtain the measurement results of all the adjacent cells to be measured, so that the terminal equipment can be ensured to successfully complete the cell measurement as soon as possible, and finally the cell measurement efficiency and the success rate of the terminal equipment can be improved.
In one possible design, the MiIt may also conform to the formula: mi=k*Mi-1Wherein k is an integer greater than 2, Mi-1And the number of gap contained in the gap period configured for the terminal equipment by the base station last time.
By this design, the base station can multiply the number of gaps. The multiple k may be set by considering the requirements of the actual scene on the cell measurement efficiency and the success rate, and/or the requirements on the throughput rate of the terminal device. For example, in order to minimize the influence of cell measurement on the throughput of the terminal device, the value of k may be set to 2.
In one possible design, the MiThe offset difference of two adjacent gaps in each gap is equal to or greater than L-x, where L is the gap length configured by the base station for the terminal device, and x is a positive number less than L. Illustratively, to avoid time jitter, x may be set to 1 ms.
In a possible design, in order to accelerate the reporting time of the measurement report of the terminal device, so that the base station may perform cell handover or add SCG to the terminal device as soon as possible, the first measurement configuration information may be further configured to notify that the reporting policy of the measurement report is periodic trigger, or a reporting policy that the arrival time is prior in periodic trigger or event trigger is preferred.
In one possible design, after the base station sends the first measurement configuration information to the terminal device, the method further includes: the base station sends second measurement configuration information to the terminal equipment;
wherein the second measurement configuration information is used to inform: the terminal equipment stops cell measurement; or
The second measurement configuration information is used to inform at least one of:
the number of the gaps contained in the gap period and used for the terminal equipment to measure the cells is recovered to 1;
and adjusting the gap period value used by the terminal equipment for cell measurement from S1 to S2, wherein S2> S1.
Due to the fact that the number of gaps for cell measurement performed by the terminal device in one gap period is increased, the service throughput rate of the terminal device may be affected, and therefore through the design, the base station may send second measurement configuration information to the terminal device to compensate the service throughput rate of the terminal device.
In one possible design, the S2 may conform to the formula: s2 ═ b × S1, where b is an integer greater than 2.
In one possible design, before the base station sends the first measurement configuration information to the terminal device, the method further includes: and the base station determines that the cell measurement of the terminal equipment fails.
In a second aspect, an embodiment of the present application provides a measurement configuration method, which may be applied in various scenarios in which inter-frequency/inter-system measurement needs to be performed in a gap measurement manner in the communication system shown in fig. 2. The method comprises the following steps: the terminal equipment receives first measurement configuration information from a base station, wherein the first measurement configuration information is used for informing that M is contained in a gap periodiA gap, M used for the terminal equipment to measure the celliIs an integer greater than 1; the terminal equipment determines the M in a gap period according to the first measurement configuration informationiThe location of each gap, and cell measurements are made within each gap.
In one possible design, the M is included in the first measurement configuration informationiThe offset of each of the individual gaps; or the first measurement configuration information includes the MiThe offset of the first of the individual gap.

Detailed Description
The application provides a measurement configuration method and equipment, which are used for improving the probability that a measurement gap covers all reference signals of adjacent cells to be measured in the process of cell measurement of terminal equipment and improving the cell measurement efficiency of the terminal equipment. The method and the device are based on the same technical conception, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.
1) A terminal device is a device that provides voice and/or data connectivity to a user. The terminal device may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and so on.
For example, the terminal device may be a handheld device, a vehicle-mounted device, or the like having a wireless connection function. Currently, some examples of terminal devices are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.
2) And the base station is a device for accessing the terminal device to the wireless network in the communication system. The base station serves as a node in a radio access network, and may also be referred to as a network device, and may also be referred to as a Radio Access Network (RAN) node (or device).
Currently, some examples of base stations are: a gbb, an evolved Node B (eNB), a Transmission Reception Point (TRP), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., a home evolved Node B or a home Node B, HNB), or a Base Band 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. The structure separates the protocol layers of the eNB in a Long Term Evolution (LTE) system, the functions of part of the protocol layers are controlled in the CU in a centralized way, the functions of the rest part or all of the protocol layers are distributed in the DU, and the CU controls the DU in a centralized way.
3) And the measurement configuration information is sent to the terminal equipment by the base station and is used for enabling the terminal equipment to carry out cell measurement according to the measurement configuration information. Generally, the base station may transmit the measurement configuration information through RRC signaling. The measurement configuration information may include, but is not limited to, at least one of the following measurement parameters: measurement object, neighbor cell list to be measured, or gap configuration parameters (gap period, gap length, start position of gap).
In this embodiment of the present application, after the base station sends the measurement configuration information to the terminal device once, the base station may further instruct the base station to adjust the value of the at least one measurement parameter by sending the measurement configuration information again. In this way, the base station can flexibly reconfigure the measurement parameters.
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 value of the adjusted measurement parameter.
The measurement configuration information includes an adjustment value of the measurement parameter, and the adjustment value may be a difference between an adjusted value and a value before adjustment of the measurement parameter.
The measurement configuration information includes an adjustment indication of the measurement parameter. The terminal device may determine the value of the adjusted measurement parameter according to the adjustment instruction of the measurement parameter and in a manner agreed with the base station.
4) And the measurement report is obtained after the terminal equipment performs cell measurement and is reported to the base station.
When the terminal device receives the reference signal of at least one neighboring cell to be measured in the gap, the measurement report may include a measurement result of the terminal device on the at least one neighboring cell to be measured (the measurement result of the at least one neighboring cell to be measured is an actual measurement value), or include measurement results of all neighboring cells to be measured (where the measurement result of the neighboring cell to be measured where the terminal device does not receive the reference signal is null or zero).
Under the condition that the terminal device does not receive the reference signal of the neighboring cell to be measured in the gap, the terminal device may not report the measurement report, or the reported measurement report is empty, or the measurement result of each neighboring cell to be measured in the reported measurement report is empty or zero.
For example, the measurement result of each neighboring cell to be measured may be a signal quality parameter of the neighboring cell to be measured. Optionally, the signal quality parameter may comprise 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 (RSRQ).
5) "and/or" describe the association relationship of the associated objects, indicating that there may be three relationships, e.g., a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the present application, the plural number means two or more.
In addition, it is to be understood that the terms first, second, etc. in the description of the present application are used for distinguishing between the descriptions and not necessarily for describing a sequential or chronological order.
The conventional gap measurement method will be described below.
The kinds of cell measurements include: common-frequency measurement and different-frequency/different-system measurement. The same-frequency measurement means that the adjacent cell to be measured and the serving cell of the terminal device are in the same carrier frequency point. The pilot frequency/system measurement means that the adjacent cell to be measured and the serving cell of the terminal device are not on the same carrier frequency point.
Generally, terminal equipment receives and transmits signals through a radio frequency path, and a set of radio frequency path generally works on a carrier frequency point.
In the process of initial access or RRC connection state of the terminal equipment, under the condition that a plurality of sets of radio frequency channels are arranged in the terminal equipment, the terminal equipment can use one set of radio frequency channels to adjust to the carrier frequency point of the serving cell so as to receive signals of the serving cell and send signals to the serving cell, and meanwhile, the terminal equipment can also adjust other radio frequency channels to the carrier frequency point of the adjacent cell so as to receive reference signals of the adjacent cell. Thus, the terminal equipment can carry out cell measurement under the condition of not suspending service transmission.
However, in the case that only one set of radio frequency paths is set inside the terminal device, as shown in fig. 1A, the terminal device cannot perform service transmission and cell measurement simultaneously, because the terminal device needs to adjust the radio frequency paths to the carrier frequency points of the serving cell to receive and send signals of the serving cell; and in the gap, the terminal equipment stops interacting with the serving cell and adjusts the radio frequency channel to a carrier frequency point of the adjacent cell so as to receive a reference signal of the adjacent cell.
And the base station transmits the measurement configuration information to the terminal equipment so as to configure the gap measurement of the terminal equipment. In the gap configuration parameters in the measurement configuration information, the value of the gap period (i.e., MGRP) may be 40ms, 80ms, or the like; the value of gap length (MGL) is 6ms at most; the amount of gap offset (gapoffset) may range from 0 to 39, or from 0 to 79, etc. The terminal device may calculate the time domain position of the gap according to the above gap configuration parameters, as shown in fig. 1B. Specifically, the terminal device may 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;
the SFN is a system frame number of a serving cell of the terminal device, and the subframe is a subframe in the system frame of the SFN.
In order to ensure the cell measurement efficiency of the terminal device and improve the success rate of cell measurement of the terminal device, the terminal device should be able to receive the reference signals of all the neighboring cells to be measured in the gap configured for the terminal device by the base station, so that the terminal device can realize the measurement of all the 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 neighbor cell is determined according to the timing of the corresponding neighbor cell.
For example, The fourth generation (The 4)thGeneration, 4G) communication technology, Cell Reference Signals (CRS), which are reference signals of a Long Term Evolution (LTE) cell, are uniformly distributed on each subframe.
As another example, see FIG. 1C, fifth generation (The 5)thGeneration, 5G) communication technology, a Synchronization Signal Block (SSB), which is a reference signal of a New Radio (NR) cell, is sent periodically, and a plurality of SSBs may be sent in a period, but all the SSBs are concentrated in a certain time window in the period to form an SSB burst. The SSB period may be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms, and the SSB periods of different NR cells may also be different. For example, assuming an SSB period of 20ms, SSB bursts may be transmitted concentrated in the first or second 5 ms.
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 contain the time domain positions of the reference signals of some neighbor cells to be measured. Assuming that the gap period is 40ms and the SSB period of the neighbor cell is 20ms, as shown in fig. 1D, the terminal device may be able to receive only the reference signal of the neighbor cell a and not the reference signal of the neighbor cell b within the gap of each gap period. Obviously, this will cause the terminal device not to receive the reference signals of all the neighboring cells to be measured in the gap at the fixed location, and thus cannot complete the measurement of all the cells to be measured, and further cause the cell measurement of the terminal device to continuously fail.
In order to solve the above problems, the present application provides a measurement configuration method and apparatus. In the solution provided in the embodiment of the present application, the base station may notify the terminal device to perform cell measurement subsequently using multiple gaps in the same gap period. Therefore, in the subsequent cell measurement process, the probability that the terminal equipment receives the reference signals of the adjacent cells to be measured in a plurality of gaps of one gap period can be improved, and therefore, the method can improve the success rate and the efficiency of the cell measurement of the terminal equipment.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 2 shows an architecture of a possible communication system to which the measurement configuration method provided in the embodiment of the present application is applicable. Referring to fig. 2, the communication system includes: a base station 201 (e.g., base station 201a, base station 201b, base station 201c, etc. in the figure), and a terminal apparatus 202.
The base station 201 is responsible for providing radio access related services for the terminal device 202, and implements radio physical layer functions, resource scheduling and radio resource management, Quality of Service (QoS) management, radio access control, and mobility management (e.g., cell reselection and handover) functions.
Each base station 201 is responsible for managing at least one cell. As shown, 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 the communication system, each cell provides access service for terminal equipment by using corresponding carrier frequency points. It should be noted that the frequency points used by different cells may be the same or different. In addition, the communication technology used by each cell is not limited in the present application, and the communication technologies used by different cells may be the same or different. For example, cell a, cell B, cell C, and cell D are LTE cells using 4G communication technology; or the cell A, the cell B, the cell C and the cell D are all NR cells using the 5G communication technology; or part of the cells A, B, C and D are LTE cells and part of the cells are NR cells.
The terminal device 202 is a device that accesses a 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 that communication between the terminal device 202 and the base station 201 is realized.
In addition, The architecture shown in fig. 2 can be applied to various communication scenarios, for example, a fifth Generation (5G) communication system, a future sixth Generation communication system and other communication systems that evolve, a Long Term Evolution (Long Term Evolution, LTE) communication system, a vehicle to anything (V2X), a Long Term Evolution-vehicle networking (LTE-V), a vehicle to vehicle (V2V), a vehicle networking, a Machine Type communication (Machine Type Communications, MTC), an internet of things (MTC), an IoT, a Long Term Evolution-Machine to Machine (LTE-Machine to Machine, LTE-M), a Machine to Machine (M2M), and other communication scenarios.
The measurement configuration method provided in the embodiment of the present application is applicable to various scenarios in which inter-frequency/inter-system measurement needs to be performed in a gap measurement manner in a communication system as shown in fig. 2, for example, an LTE measurement scenario in a 4G communication technology, and the following scenarios in a 5G communication technology that support a Dual Connectivity (DC) technology: an EN-DC (EUTRA-NR Dual Connectivity) scenario, a NE-DC (NR-EUTRA Dual Connectivity), a NR-DC, and a non-DC scenario, an SA scenario and an NSA scenario in 5G communication technologies.
It is assumed that the terminal device 202 accesses a cell a (cell a is a serving cell) managed by the base station 201a, and a cell B, a cell C, and a cell D are neighbor cells determined by the base station 201a for the terminal device 202.
For example, in an LTE measurement scenario and a non-DC scenario, the base station 201a sends measurement configuration information to the terminal device 202, where the measurement configuration information includes a gap configuration parameter and a neighbor cell list 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, performs cell measurement in the gap, and reports a measurement report to the base station 201a after the measurement is completed; the base station 201a switches the terminal device to the cell with better signal quality according to the signal quality parameters of each cell in the measurement report.
For another example, in each scenario supporting the dual connectivity technology, cell a is a primary cell (PCell) of terminal device 202, and base station 201a is a primary base station of terminal device 202. The base station 201a sends measurement configuration information to the terminal device 202, where the measurement configuration information includes a gap configuration parameter and a to-be-measured neighbor cell list (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, performs cell measurement in the gap, and reports 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 parameter of each cell in the measurement report, thereby implementing addition of a Secondary Cell Group (SCG) to the terminal device 202.
In order to improve the success rate and efficiency of cell measurement of a terminal device, the embodiment of the application provides a measurement configuration method. The method can be applied to various scenarios in which inter-frequency/inter-system measurement needs to be performed in a gap measurement manner in the communication system shown in fig. 2. By the scheme, the base station can inform the terminal equipment of using a plurality of gaps to measure the cells in the same gap period. Therefore, in the subsequent cell measurement process, the probability that the terminal equipment receives the reference signals of all the to-be-measured neighbor cells in a plurality of gaps of one gap period can be improved, and therefore, the method can improve the success rate and the efficiency of the cell measurement of the terminal equipment.
The following describes a measurement configuration method provided in an embodiment of the present application with reference to a 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 the present application, and the measurement configuration method provided in the present application may include more or less steps than the method shown in fig. 3.
S301: the base station sends first measurement configuration information to the terminal equipment, wherein the first measurement configuration information is used for configuring gap used when the terminal equipment carries out cell measurement. The terminal device receives the first measurement configuration information from the base station.
For example, the first measurement configuration information may be conventional measurement configuration information, which may include gap configuration parameters (gap period, gap length, and gap offset), and may further include information such as a list of neighboring cells to be measured, a reporting policy of a measurement report, and the like. For example, the first measurement configuration information may be measurement gap configuration (measGapConfig) signaling or measurement configuration (measConfig) signaling.
The length of the gap configured for the terminal device by the base station through the first measurement configuration information may be, but is not limited to, the gap length specified for the LTE communication technology, which is 6 ms. In the following description and examples of the embodiments of the present application, the determination of the location of the gap used in the current cell measurement is performed by taking L ═ 6 as an example only (where the number of gaps in the gap period is 1, that is, M01) as shown in fig. 1B, and performs cell measurement within the determined gap. Wherein the length of gap is L, the period of gap is S1, and the offset of gap is f0
In this embodiment, the performing, by the terminal device, cell measurement in a gap includes: and the terminal equipment receives the reference signal of the adjacent cell to be measured in the gap and determines the measurement result of the adjacent cell to be measured.
It should be noted that, reference signal time domain positions of all neighboring cells to be measured may not be covered in the gap, for example, as shown in fig. 1D, and therefore, in the gap, the terminal device may receive only reference signals of some cells to be measured, or may not receive reference signals of all cells to be measured, and at this time, the terminal device fails to measure the cells.
In case of cell measurement failure of the terminal device, the terminal device may notify the base station by, but not limited to:
the first method is as follows: the terminal device may not send the measurement report to the base station according to a reporting policy of the measurement report, or according to a protocol or an agreement with the base station.
The second method comprises the following steps: the terminal device may send a measurement report carrying measurement results of part of the neighboring cells to be measured to the base station.
The third method comprises the following steps: the terminal device may send a measurement report carrying measurement results of all neighboring cells to be measured to the base station, and the measurement result of the neighboring cell to be measured that is not measured by the terminal device in the measurement report is invalid. For example, the measurement result of the cell to be measured that is not measured by the terminal device may be null, zero, or an indicator indicating that the measurement result is invalid.
The method is as follows: the terminal device may send a notification message to the terminal device, where the notification message is used to notify the base station to: the terminal device cell measurement fails.
S303: and when the terminal equipment informs that the cell measurement of the base station fails in the second mode or the third mode, the terminal equipment sends a first measurement report to the base station. The base station receives the first measurement report from the terminal device. As shown, this step is an optional step.
When the terminal equipment adopts the second mode, the first measurement report comprises measurement results of part of adjacent cells to be measured; when the terminal device adopts the third mode, the first measurement report includes measurement results of all cells to be measured, and only the measurement result of the neighboring cell to be measured by the terminal device is valid.
S304: and the base station determines that the cell measurement of the terminal equipment 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 determine that the terminal device has the cell measurement failure by:
the first method is as follows: and the base station does not receive a measurement report from the terminal equipment within a set time length, and determines that the cell measurement of the terminal equipment fails.
The second method comprises the following steps: the base station receives a first measurement report from the terminal equipment, and when the base station determines that the first measurement report does not contain the measurement results of all cells to be measured, the base station determines that the cell measurement of the terminal equipment fails.
The third method comprises the following steps: the base station receives a first measurement report from the terminal equipment, and when the base station determines that the measurement result of a part of cells to be measured in the first measurement report is invalid, the base station determines that the cell measurement of the terminal equipment fails.
The method is as follows: and when the base station receives the notification message from the terminal equipment, determining that the cell measurement of the terminal equipment fails.
S304 a: the base station increases the number of gaps used by the terminal equipment in the subsequent cell measurement in the gap period, and determines that the gap period contains MiA gap, M used for the terminal equipment to perform the subsequent cell measurementiIs an integer greater than 1.
Optionally, in this embodiment of the present application, the base station may increase the number of gap in a gap period by, but is not limited to, determining M1. Wherein, i is the number of times of adjusting the number of gap, and when adjusting for the first time, i is 1.
The first method is as follows: miAccording to the formula:
Figure BDA0002391851490000101
t1 is the reference signal transmission period of the neighbor cell to be measured. In the scenario where the amount of gap is first adjusted,
Figure BDA0002391851490000102
wherein r is a positive number less than or equal to L, and L is configured for the terminal equipment by the base stationgap length.
In order to improve the cell measurement efficiency and the success rate of the terminal equipment, the MiThe offset difference between two adjacent gaps in the gaps may be less than or equal to the length L of the gap, where L may be 6ms, and r may be set to 5ms to avoid the influence of delay jitter on cell measurement. Since the terminal device can continuously pass through the M in the gap periodiThe cell measurement is continuously performed by each gap, so that the method can ensure that the terminal equipment receives the reference signals of all the adjacent cells to be measured in the gap period, thereby ensuring that the terminal equipment can successfully complete the cell measurement as soon as possible.
In addition, as a result of the first mode, MiEach gap can cover the time domain position of the reference signal of all the neighbor cells to be measured, so the base station can use the offset f of the last configured gap0Or reset the offset of the new gap.
Wherein, when MiWhen the offset between the offsets of every two adjacent gaps in each gap is a fixed value or the base station has been configured, the base station may configure only the MiOffset f of the first of the individual gapi,a(ii) a Or the base station reconfigures the MiThe offset of each of the individual gaps.
The second method comprises the following steps: the base station may reject the gap position used in the gap period for the last cell measurement failure. MiAccording to the formula:
Figure BDA0002391851490000103
and said M isiOffset f of the first of the individual gapi,aThe formula may be followed: f. ofi,a=fi-1,b+ r. Wherein, T1 is the reference signal transmission period of the adjacent cell to be measured, Mi-1The number of gap contained in the gap period configured for the terminal equipment by the base station last time, fi-1,bAnd the offset of the last gap in the gap period configured for the terminal equipment by the base station last time.
In the scenario where the amount of gap is first adjusted,
Figure BDA0002391851490000104
and f is1,a=f0+r。
Similarly, since the terminal device has already performed cell measurement at the last gap position and cell measurement fails (measurement results of all neighboring cells to be measured are not obtained), removing the gap position allows the terminal device to still perform cell measurement at the next gap periodiAnd receiving the reference signals of other adjacent cells to be measured in the gap so as to obtain the measurement results of the other cells to be measured.
Wherein, when MiWhen the offset between the offsets of every two adjacent gaps in each gap is a fixed value or the base station has been configured, the base station may configure only the MiOffset f of the first of the individual gapi,a(ii) a Or the base station reconfigures the MiThe offset of each of the individual gaps.
Obviously, in the second mode, the terminal device and the base station may combine the measurement result obtained from the previous cell measurement and the measurement result obtained from the current cell measurement to obtain the measurement results of all the neighboring cells to be measured, so as to ensure that the terminal device can successfully complete the cell measurement as soon as possible, and finally improve the cell measurement efficiency and the success rate of the terminal device.
The third method comprises the following steps: mi=k*Mi-1Wherein k is an integer greater than 2, Mi-1And the number of gap contained in the gap period configured for the terminal equipment by the base station last time.
In the third mode, the base station may multiply the number of gaps. The multiple k may be set by considering the requirements of the actual scene on the cell measurement efficiency and the success rate, and/or the requirements on the throughput rate of the terminal device. For example, in order to minimize the influence of cell measurement on the throughput of the terminal device, the value of k may be set to 2.
Wherein, when MiThe offset between the offsets of every two adjacent gaps in each gap is a fixed value or when the base station is configured, the base stationA station may configure only the MiOffset f of the first of the individual gapi,a(ii) a Or the base station reconfigures the MiThe offset of each of the individual gaps. In the scenario where the amount of gap is first adjusted, f1,a=f0Or f is1,a=f0+ r (i.e. the gap location used for the last cell measurement failure in the gap period is rejected).
In addition, in order to accelerate the reporting time of the measurement report of the terminal device, so that the base station can perform cell switching or add SCG to the terminal device as soon as possible, the base station may further adjust the reporting policy of the measurement report to be: a periodic trigger, or a reporting policy with a preferred arrival time prior in the periodic trigger or event trigger.
S305: and the base station sends second measurement configuration information to the terminal equipment. Wherein the second measurement configuration information is used for notifying that M is contained in a gap period1And the gap is used for the terminal equipment to measure the cell. The terminal device receives the second measurement configuration information from the base station.
As can be seen from the above description, the second measurement configuration information may include: the M isiThe offset of each of the individual gaps. Alternatively, the second measurement configuration information may include the MiOffset f of the first of the individual gapi,aOf course, the offset difference between every two adjacent gap can also be included. In addition, the second measurement configuration information may further include a gap number M configured by the base stationiAnd the like.
When the base station further determines to adjust the reporting policy of the measurement report in S304a, correspondingly, the second measurement configuration information is further used to notify that the reporting policy of the measurement report is a periodic trigger, or a reporting policy with a preferred arrival time prior in the periodic trigger or event trigger.
Optionally, the second measurement configuration information may be a plurality of information, for example, the second measurement configuration information may include, but is not limited to: signaling 1 containing gap configuration information and signaling 2 for configuring reporting strategy of measurement result. Of course, the signaling 1 may include an indication for keeping the gap length and the gap period unchanged, or include the gap length L and the gap period S1 configured for the base station last time, and may further include the MiAnd the offset of the first gap in the gap, the offset of each gap, or the offset difference between two adjacent gaps.
S306: the terminal equipment determines the M used by the next cell measurement in a gap period according to the second measurement configuration informationiThe location of each gap, and cell measurements are made within each gap.
In this step, the terminal device may determine the M according to the gap length and the gap period configured by the base station, and content (offset configuration information such as the number of gaps, the offset of the first gap, the offset of each gap, or the offset difference between two adjacent gaps) included in the second measurement configuration informationiThe position of each gap.
In this step, the process of the terminal device performing cell measurement in each gap is the same as S302, so the process of the terminal device performing cell measurement may refer to the description of S302 above, and is not described herein again.
In addition, for various reasons, after performing cell measurement for each gap, the cell measurement of the terminal device may succeed or may fail. When the cell measurement of the terminal device is successful (the measurement results of all cells to be measured are obtained through the first cell measurement until the current cell measurement), the terminal device may send a second measurement report to the base station through S307 after the cell measurement; when the cell measurement of the terminal device fails, the terminal device may also notify the base station that the cell measurement of this time fails in the 4-step method described in S302.
It should be noted that, in the case that the terminal device sends a measurement report to the base station after each cell measurement, the measurement report sent by the terminal device each time may only include the measurement result of the neighboring cell to be measured that is measured this time, or may include the measurement result of the neighboring cell to be measured that is measured this time and each time before, which is not limited in this application. When the terminal device does not send a measurement report to the base station after cell measurement fails, and the terminal device determines that cell measurement is successful, the measurement report sent to the base station includes measurement results of all neighboring cells to be measured, which are measured by the terminal device at this time and every time before.
S307: and the terminal equipment sends a second measurement report to the base station. The base station receives the second measurement report from the terminal device. As shown, this step is an optional step.
And when the second measurement configuration information is also used for indicating a reporting strategy of a measurement report, the terminal equipment reports the second measurement report according to the reporting strategy.
S308: and the base station determines that the cell measurement of the terminal equipment is successful according to the second measurement report.
Optionally, the base station may also determine that the terminal device fails to perform the cell measurement in S304, and then, the base station may further increase the number of gap again (refer to S304a-S308 in the specific process), or adjust the MiAnd configuring the gap used by the terminal equipment in a gap offset mode until the cell measurement of the terminal equipment is successful.
S309: the base station may send third measurement configuration information to the terminal device after S305 or after S308 determines that the terminal device cell measurement is successful. And the base station of the terminal equipment receives the third measurement configuration information.
In one embodiment, the third measurement configuration information is used to indicate: and the terminal equipment stops 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 equipment stops cell measurement within a set time period after receiving the third measurement configuration information.
In another embodiment, the third measurement configuration information may be, but is not limited to, for indicating at least one of:
the number of the gaps contained in the gap period and used for the terminal equipment to measure the cells is recovered to 1;
and adjusting the gap period value used by the terminal equipment for cell measurement from S1 to S2, wherein S2> S1. Illustratively, the S2 conforms to the formula: s2 ═ b × S1, where b is an integer greater than 2.
As can be seen from the above description, in S306 the terminal device continuously passes through M within one gap periodiThe cell measurement is performed by each gap, and although the success rate of the cell measurement performed by the terminal device through S306 is high, this may affect the service throughput of the terminal device. In summary, according to any of the above embodiments, the subsequent service throughput rate of the terminal device can be ensured or improved.
S310: in the case that the third measurement configuration information is the first embodiment, the terminal device does not perform cell measurement any more. In the case that the third measurement configuration information is the second embodiment, the terminal device determines the location of the gap used in the next cell measurement again according to the number and/or period of the gaps indicated by the third measurement configuration information, and performs the cell measurement within the determined gap.
In this step, the process of the terminal device performing cell measurement within the determined gap is the same as S302, so the process of the terminal device performing cell measurement may refer to the description of S302 above, and is not described herein again.
Of course, after the terminal device performs cell measurement, the base station may also be notified of the measurement result of the terminal device on the neighboring cell to be measured.
It should be further noted that, in this embodiment of the present application, the sending, by the base station, each measurement configuration information to the terminal device, and the sending, by the terminal device, a measurement report or a notification message to the base station may be implemented by RRC signaling, which is not limited in this application.
In the measurement configuration method provided in the embodiment of the present application, after determining that the cell measurement of the terminal device fails, the base station notifies the terminal device to subsequently use multiple gaps to perform cell measurement in the same gap period. Therefore, in the subsequent cell measurement process, the probability that the terminal equipment receives the reference signals of the adjacent cells to be measured in a plurality of gaps of one gap period can be improved, and therefore, the method can improve the success rate and the efficiency of the cell measurement of the terminal equipment.
Based on the embodiment shown in fig. 3, the present application also provides an example of a method for adjusting the number of gap. As shown in fig. 4A. The base station may configure that the number of the gaps becomes one gap period after determining that the cell measurement of the terminal device fails
Figure BDA0002391851490000131
In order to prevent time jitter and improve the service throughput of the terminal device as much as possible, the offset difference between two adjacent gaps is L-x, that is, there is an overlapping portion with length x between two adjacent gaps.
As shown in fig. 4A, it is assumed that the gap configuration first configured by the base station for the terminal device is that the offset of the gap is 0ms, the gap period is 40ms, and the gap length is 6 ms; the number of the neighbor cells to be measured configured for the terminal equipment by the base station is 4, and the transmission period of the reference signal of each neighbor cell to be measured is 20 ms. The base station may adjust the number of gap for one gap period to 4, and the offset of the first gap is the same as the gap offset configured for the terminal device last time.
In this way, the terminal device may receive the reference signal of the neighboring cell to be measured 1 in the gap1, … …, and receive the reference signal of the neighboring cell to be measured 4 in the gap4, and finally, the terminal device may measure the measurement results of all the neighboring cells to be measured through 4 times of cell measurements, thereby achieving successful cell measurement as soon as possible. The example can improve the efficiency and success rate of cell measurement of the terminal device.
Based on the embodiment shown in fig. 3, the present application also provides another example of the method for adjusting the amount of gap. As shown in fig. 4B. The base station may be configured at one after determining that the cell measurement of the terminal device failsThe number of gap periods becomes
Figure BDA0002391851490000132
In order to ensure the throughput rate of the terminal equipment, the base station eliminates the gap position used by the last cell measurement of the terminal equipment. In addition, in order to prevent time jitter and improve the service throughput of the terminal device as much as possible, the offset difference between two adjacent gaps is L-x, that is, there is an overlapping portion with length x between two adjacent gaps.
As shown in fig. 4B, it is assumed that the gap configuration first configured by the base station for the terminal device is that the offset of the gap is 0ms, the gap period is 40ms, and the gap length is 6 ms; the number of the neighbor cells to be measured configured for the terminal equipment by the base station is 4, and the transmission period of the reference signal of each neighbor cell to be measured is 20 ms. The base station may adjust the number of gap for one gap period to 3, and the offset of the first gap is increased by 5ms compared to the gap offset configured for the terminal device last time.
In this way, the terminal device may receive the reference signal of the neighboring cell to be measured 2 in the gap1, … …, and the reference signal of the neighboring cell to be measured 4 in the gap3, and finally, the terminal device may measure the measurement result of the neighboring cell to be measured 2-4 through 3 cell measurements, and in combination with the previously measured measurement result of the neighboring cell to be measured 1, the terminal device achieves successful cell measurement. The embodiment can also improve the efficiency and the success rate of the cell measurement of the terminal equipment, and can also reduce the influence of the cell measurement on the throughput rate of the terminal equipment.
Based on the embodiment shown in fig. 3, the present application further provides another example of a method for adjusting the amount of gap. As shown in fig. 4C and 4D. After determining that the cell measurement of the terminal device fails, the base station may configure that the number of the gaps in one gap period is 2 times of the original number. In order to ensure the throughput rate of the terminal device, the base station may remove the gap position used in the last cell measurement of the terminal device.
In addition, in order to prevent time jitter and improve the traffic throughput of the terminal device as much as possible, the offset difference between two adjacent gaps is L-x, i.e. there is an overlapping portion with length x between two adjacent gaps, as shown in fig. 4C.
The base station may also disperse the positions of the gaps to cover as many reference signal time domain positions of the neighboring cells to be measured as possible (i.e. the offset difference between two adjacent gaps is greater than 6ms), as shown in fig. 4D.
Assuming that the gap configuration firstly configured by the base station for the terminal equipment is that the offset of the gap is 0ms, the gap period is 40ms, and the gap length is 6 ms; the number of the neighbor cells to be measured configured for the terminal equipment by the base station is 4, and the transmission period of the reference signal of each neighbor cell to be measured is 20 ms.
As shown in fig. 4C, after determining that the cell measurement of the terminal device fails, the base station sets the number of gaps in one gap period to 2, and the offset difference between the two gaps is 5 ms. In this way, the terminal device can receive the reference signal of the neighboring cell to be measured 2 in the gap1 and the reference signal of the neighboring cell to be measured 3 in the gap 2. Although the terminal equipment still fails in cell measurement, the terminal equipment can obtain the measurement results of two adjacent cells to be measured through the two cell measurements. As long as the terminal device obtains the measurement result of the neighboring cell 4 to be measured through subsequent cell measurement, the terminal device can realize successful cell measurement by combining the previously measured measurement results of the neighboring cells 1 to 3 to be measured. The embodiment can also improve the efficiency and the success rate of the cell measurement of the terminal equipment, and can also reduce the influence of the cell measurement on the throughput rate of the terminal equipment.
As shown in fig. 4D, after determining that the terminal device fails to perform cell measurement, the base station sets the number of gaps in one gap period to 2, and the offset difference between the two gaps is 8 ms. In this way, the terminal device can receive the reference signal of the neighboring cell to be measured 2 in the gap1, and receive the reference signals of the neighboring cell to be measured 3 and the neighboring cell to be measured 4 in the gap 2. Finally, the terminal device can measure the measurement results of the adjacent cells to be measured 2-4 through the two cell measurements, and the terminal device realizes successful cell measurement by combining the measurement results of the adjacent cell to be measured 1 measured before. The embodiment can also improve the efficiency and the success rate of the cell measurement of the terminal equipment, and can also reduce the influence of the cell measurement on the throughput rate of the terminal equipment.
It should be noted that, when the base station adopts the example shown in fig. 4C or fig. 4D, after the number of gap in the gap period is doubled, the terminal device still fails to perform measurement, and the subsequent base station may continue to double the number of gap in the gap period, so that the number of gap in the gap period becomes 4, 8, 16, and so on, until the terminal device succeeds in cell measurement; or the subsequent base station does not increase the number of the gap any more, and only adjusts the offset of the gap, so that the adjusted gap can cover the reference signal time domain position of the adjacent cell to be measured, which is not measured by the terminal equipment, and the cell measurement is completed as soon as possible.
