The single Cell Reference Signal may be a Cell-Specific Reference Signal (CRS), a Channel State Information Reference Signal (CSI-RS), a Reduced Cell-Specific Reference Signal (RCRS), and the like, and the present invention does not limit the type of the Cell Reference Signal for performing single Cell measurement. In the following, the measurement feedback of the present invention is described in detail by taking CRS as a single cell reference signal as an example, and any other single or regional reference signal may be used instead of CRS. For simplicity, the measurement based on the single-cell reference signal is referred to as single-cell measurement, and the measurement based on the multicast broadcast single frequency network reference signal is referred to as multicast measurement.

In a specific implementation process, the Network may transmit data to a terminal (User Equipment, UE) by using a Single cell, or may transmit data to the terminal by using a Single Frequency Network (SFN) through multiple cells by using a Multimedia Broadcast Multicast Service (MBMS). When a base station adopts single cell transmission data, the base station sends a cell-specific reference signal CRS to a terminal. Correspondingly, the base station sends a Multicast Broadcast Single Frequency Network Reference Signal (MBSFN RS) to the terminal when the MBMS data transmission is performed. Therefore, the terminal performs S101 cell coverage measurement based on CRS and MBSFN RS.

In S101, the terminal performs Multicast measurement based on a Multicast Broadcast Single Frequency Network Reference Signal to obtain a Multicast measurement result, where the Multicast measurement result includes Reference Signal Received Power (RSRP) of an MBSFN RS and a Received Signal Strength Indicator (RSSI) of a Multicast Broadcast Single Frequency Network (MBSFN), and may determine Reference Signal Received Quality (MRSRQ) according to a formula M × MRSRP/MRSSI, where MRSRP represents the Reference Signal Received Power of the MBSFN RS, MRSSI represents the Received Signal Strength Indicator of the MBSFN, and M represents the number of resource blocks in the MBSFN area for measuring MRSSI. On the same carrier, a wireless network includes multiple cells, wherein one multicast broadcast single frequency network area (MBSFN area) includes one or more cells, and other cells are not included in the multicast broadcast single frequency network area. When receiving the MBSFN area signal, the terminal may also receive the interference signal, such as CRS, of other single cells outside the area, so that the terminal performs single cell measurement based on the cell-specific reference signal to obtain a single cell measurement result, where the single cell measurement result includes the reference signal received power of the single cell reference signal, and RSRP is used to represent the reference signal received power of the single cell reference signal (where CRS measurement is performed based on the cell-specific reference signal), so as to determine the interference degree of the signal of the single cell to the MBSFN area transmitted signal.

After the terminal executes S101 to obtain the single cell measurement result and the multicast measurement result, the terminal executes S102 to report according to the single cell measurement result and the multicast measurement result. Specifically, the measurement report may be a direct report of the single cell measurement result and the multicast measurement result, or a report of a result obtained by calculation according to the single cell measurement result and the multicast measurement result and a multicast measurement result. The above measurement report of the terminal enables the network control node to obtain report information related to the measurement result from the base station and quickly adjust the cell serving the terminal or adjust the composition of the MBSFN area according to the report information of the terminal, and specifically, the network control node can obtain reference signal reception quality MRSRQ in the multicast broadcast single frequency network according to MRSRP and MRSSI and adjust the reference signal reception quality MRSRQ based on MRSRQ and RSRP. For example, when RSRP is large, large interference is caused to the multicast broadcast single frequency network, and the reference signal reception quality in the multicast broadcast single frequency network is low at this time, the base station may consider adding a single cell with strong interference to the multicast broadcast single frequency network, so as to enhance the signal power and the signal quality of the multicast broadcast single frequency network; conversely, when RSRP is very small, interference to the multicast broadcast single frequency network is very small, and the reference signal reception quality in the multicast broadcast single frequency network is very high at this time, the base station may consider to remove one cell from the multicast broadcast single frequency network, and the removed cell may be used for single-cell data transmission, thereby increasing single-cell data transmission resources, and facilitating improvement of the performance of the entire network and increase of throughput of single-cell data transmission.

Therefore, when the terminal reports, the terminal not only carries out multicast measurement, but also carries out single-cell measurement, and reports the single-cell measurement result and the multicast measurement result to the base station, and the reported information not only comprises the measurement condition of the single cell, but also comprises the measurement condition of a multicast broadcast single-frequency network, so that the network coverage condition of a measurement area can be reflected more accurately. The base station can further transmit the related information reported by the terminal to the network control node, so that the network control node can obtain the related information of the measurement results of the single-cell measurement and the multicast measurement, thereby quickly optimizing the cell composition of the multimedia broadcast multicast service according to the related information of the measurement results, further solving the technical problem that the cell composition rate of the network control node for optimizing the multimedia broadcast multicast service is slow, and improving the service quality of the multimedia broadcast multicast service. The network control node may be a Mobility Management Entity (MME), a Multi-cell/Multicast Coordination Entity (MCE), and other nodes.

It should be noted that the measurement of the UE may be performed according to predefined or measurement configuration information configured by the base station; the reporting of the UE may also be performed according to predefined reporting configuration information or reporting configuration information configured by the base station. Wherein the measurement configuration information includes the following information: cell identification for single cell measurement and MBSFN area identification for multicast measurement. Measurement time and/or measurement geographical area information may also be included, without excluding further information. The reporting configuration information includes a reporting period and/or a reporting trigger condition, which does not exclude other information.

In the specific implementation process, the terminal performs the single-cell measurement and the multicast measurement which are related measurements, so that the single-cell measurement result and the multicast measurement result are ensured to have referential property with each other. Specifically, a first measurement time window for performing single cell measurement is correlated with a second measurement time window for performing multicast measurement; and/or the first measurement region where single cell measurements are made and the second measurement region where multicast measurements are made are correlated; and/or the first measurement frequency band for performing single cell measurement is correlated with the second measurement frequency band for performing multicast measurement.

When a first measurement time window for performing single-cell and area measurement is related to a second measurement time window for performing multicast measurement, the terminal obtains the related measurement time window for performing single 'j' area measurement and multicast measurement from the received measurement configuration information by receiving the measurement configuration information issued by the base station, or the terminal performs single-cell measurement and multicast measurement according to the related measurement time window predefined by the equipment. Specifically, the interval between the first time window for the terminal to perform single-cell measurement and the second time window for performing multicast measurement is smaller than the time threshold, that is, the interval between the end time of the first time window and the start time of the second time window is smaller than the time threshold, or the interval between the end time of the second time window and the start time of the first time window is smaller than the time threshold; the terminal may also perform another measurement after starting to perform the single-cell measurement or the multicast measurement and before the single-cell measurement or the multicast measurement is not completed, that is, the first time window and the second time window are partially overlapped; of course, the terminal may also perform single cell measurement and multicast measurement simultaneously in the same time window, i.e. the first time window and the second time window all overlap.

For example: in a certain measuring time period, the first time window is 9: 00: 00-9: 00: 10, and the terminal carries out single cell measurement in the time period of 9: 00: 00-9: 00: 10. If the time between the second time window and the first time window is less than a first time threshold, e.g., 5s, then the second time window for multicast measurements starts at any time between 9: 00: 10-9: 00: 15 or the second time window ends at any time between 8: 59: 55-9: 00: 00; if the second time window partially overlaps the first time window, the second time window for the terminal to perform the multicast measurement starts at any time between 9: 00: 00 and 9: 00: 10 or the second time window ends at any time between 9: 00: 00 and 9: 00: 10; if the second time window and the first time window are all overlapped, the terminal performs multicast measurement while performing single-cell measurement at 9: 00: 00-9: 00: 10.

When the terminal performs the single-cell measurement and the multicast measurement, the correlation between the single-cell measurement result and the multicast measurement result obtained by the measurement can be ensured from the measurement time, and the correlation between the single-cell measurement result and the multicast measurement result can be ensured from the measurement area. When the first measurement area for performing the single-cell measurement is related to the second measurement area for performing the multicast measurement, the terminal may obtain the related measurement areas for performing the single-cell measurement and the multicast measurement from measurement configuration information issued by the base station or device predefined information. Specifically, a first measurement area where the terminal performs single-cell measurement and a second measurement area where the terminal performs multicast measurement are partially or completely overlapped, or a distance between the first measurement area and the second measurement area is smaller than a distance threshold. Specifically, the first measurement area and the second measurement area may be geographical location areas where the terminal is located, or may be cell location areas where the terminal is located. For example: the first geographic location area for single-cell measurements by the terminal may be the same as or within a distance threshold (e.g., 10 meters) of the second geographic location area for multicast measurements by the terminal.

When the terminal performs the single-cell measurement, the area measurement and the multicast measurement, the correlation between the single-cell measurement result and the multicast measurement result obtained by the measurement can be ensured from the measurement time and/or the measurement area, and the correlation between the single-cell measurement result and the multicast measurement result can be ensured from the measurement frequency band. When the first measurement frequency band for performing single-cell measurement is related to the second measurement frequency band for performing multicast measurement, the terminal may obtain the related measurement frequency bands for performing single-cell measurement and multicast measurement from measurement configuration information issued by the base station or device predefined information. Specifically, a first measurement frequency band for performing single cell measurement by the terminal and a second measurement frequency band for performing multicast measurement are partially or completely overlapped, or an interval between the first measurement frequency band and the second measurement frequency band is smaller than a frequency band threshold. For example: the first measurement frequency band for the terminal to perform single cell measurement and the second measurement frequency band for the terminal to perform multicast measurement are the same or have an interval smaller than a frequency band threshold (for example, 720kHz or N physical resource blocks).

Certainly, when the terminal performs the single-cell measurement and the multicast measurement, not only the measurement time window meets the time requirement, but also the measurement area and/or the measurement frequency band meets the requirement, so that the mutual reference between the single-cell measurement result and the multicast measurement result on the time, the area and/or the frequency band can be further ensured.

In a specific implementation process, the terminal may obtain, from the measurement configuration information issued by the base station, which cell is specifically subjected to single cell measurement, and obtain, from the reporting configuration information issued by the base station, content that the reporting information needs to include. The measurement configuration information and the reporting configuration information may be immediately issued to the terminal by the base station according to actual needs, or issued to the terminal by the base station within a certain period. The method for the base station to issue the measurement configuration information and report the configuration information is not limited in the present invention, and may be issued by broadcast signaling, for example, by a system information block type2 (SystemInformationBlockType 2, SIB 2), a system information block type 13 (SystemInformationBlockType 3, SIB 13), a Multicast Control Channel (MCCH), MBMS, or by dedicated signaling of the terminal. For example: the base station sends the measurement configuration information and the report configuration information to the terminal through the exclusive signaling of the terminal, the measurement configuration information requires the terminal to measure the single cell A and the MBSFN, then the terminal carries out single cell measurement on the single cell A and multicast measurement on the MBSFN according to the measurement configuration information, and reports the measurement results of the single cell A and the MBSFN to the base station according to the report configuration information in a preset report mode.

In the specific implementation process, after the terminal performs the single-cell measurement and the multicast measurement to obtain the measurement result, the measurement result can be directly reported to the base station, or can be reported when a reporting requirement sent by the base station is received, the measurement result can be further judged by the terminal, and the measurement result can be reported to the base station when the single-cell measurement result and the multicast measurement result meet the reporting trigger condition. After the terminal further judges the measurement result, the measurement result is reported to the base station based on the measurement result when the reporting trigger condition is met, so that the reporting of invalid measurement information can be reduced, the electric energy is saved, and the burden of the base station is reduced.

The reporting trigger condition may be configured by the base station or predefined, and the reporting trigger condition may be one trigger condition or a combination of multiple trigger conditions. Specifically, the reporting trigger condition may include at least one of the following conditions:

(1) the ratio of the reference signal receiving power of the multicast broadcast single frequency network reference signal to the reference signal receiving power of the single cell reference signal in the single cell measurement result and the multicast measurement result obtained by the terminal is smaller than a first threshold, that is, MRSRP/RSRP is smaller than the first threshold, which indicates that the interference of the signal of the single cell to the MBSFN area is strong, and a cell may need to be added to the MBSFN area to enhance the signal receiving power and the signal receiving quality of the MBSFN area, so the terminal needs to measure the base station based on the single cell measurement result and the multicast measurement result.

(2) The ratio of the reference signal receiving power of the multicast broadcast single frequency network reference signal to the reference signal receiving power of the single cell reference signal in the single cell measurement result and the multicast measurement result obtained by the terminal is greater than a second threshold, wherein the second set threshold is greater than the first set threshold, that is, the MRSRP/RSRP is greater than the second threshold, which indicates that the interference of the signal of the single cell to the MBSFN area is very small, the MBSFN area may have excessive coverage, the base station can remove one cell from the MBSFN area, so that the removed cell is used for single cell data transmission to enhance the throughput of single cell data transmission, and therefore the terminal needs to report to the base station based on the single cell measurement result and the multicast measurement result.

(3) The first reference value after the measured single cell is added in the multicast broadcast single frequency network is greater than a third threshold value or less than a fourth threshold value, that is, the MRSRQ after the measured single cell is added in the MBSFN area is greater than the third threshold value or less than the fourth threshold value, wherein the fourth threshold value is greater than the third threshold value, which indicates that the base station may need to adjust the composition of the MBSFN cell, so that the terminal needs to report to the base station based on the single cell measurement result and the multicast measurement result. The specific algorithm of the measured MRSRQ after the single cell is added to the trigger condition is explained in detail in the following reporting calculation.

(4) The second reference value after the measured single cell is removed in the multicast broadcast single frequency network is greater than a fifth threshold or less than a sixth threshold, that is, the MRSRQ after the measured single cell is removed in the MBSFN area is greater than the fifth threshold or less than the sixth threshold, where the sixth threshold is greater than the fifth threshold, which also indicates that the base station may need to adjust the composition of the MBSFN cell, and therefore the terminal needs to report to the base station based on the single cell measurement result and the multicast measurement result. The specific algorithm of the MRSRQ after removing the measured single cell in the trigger condition is explained in detail in the following reporting calculation.

(5) The reference signal receiving power RSRP of the single cell reference signal in the single cell measurement result and the multicast measurement result obtained by the terminal is greater than the seventh threshold, which indicates that the signal receiving power of the single cell is too high, which may cause strong interference to data transmission in the MBSFN area, and the base station may need to add a cell to the MBSFN area to enhance the signal receiving power and the signal receiving quality of the MBSFN area, so that the terminal needs to report to the base station based on the single cell measurement result and the multicast measurement result.

(6) The reference signal receiving power RSRP of the single cell reference signal in the single cell measurement result and the multicast measurement result obtained by the terminal is smaller than an eighth threshold, wherein the eighth threshold is smaller than a seventh threshold, which indicates that the single cell signal receiving power received by the terminal is small enough, and the MBSFN area may have excessive coverage.

(7) And the received signal strength indication MRSSI of the MBSFN in the single cell measurement result obtained by the terminal and the multicast measurement result is smaller than a ninth threshold value according to the M times of the reference signal received power MRSRP of the multicast broadcast single frequency network MBSFN, namely the reference signal received power quality MRSRQ = M MRSRP/MRSSI of the MBSFN is smaller than the ninth threshold value. At this time, it indicates that the signal reception quality of the MBSFN area is too low, and the base station needs to correspondingly adjust the cells included in the MBSFN area, so the terminal needs to report to the base station based on the single-cell measurement result and the multicast measurement result.

(8) And the received signal strength of the MBSFN indicates that the MRSSI is greater than a tenth threshold value according to the M times of the MBSFN reference signal received power MRSRP in the single cell measurement result and the multicast measurement result obtained by the terminal, namely MRSRQ = M MRSRP/MRSSI is greater than the tenth threshold value, wherein the tenth threshold value is less than a ninth threshold value. At this time, it indicates that the signal reception quality of the MBSFN area is good, and the base station may consider to remove one cell from the MBSFN area, so that the terminal needs to report to the base station based on the single-cell measurement result and the multicast measurement result.

The reporting information reported by the terminal based on the single-cell measurement result and the multicast measurement result can be the single-cell measurement result and the multicast measurement result, or the result calculated based on the single-cell measurement result and the multicast measurement result, whether the terminal directly reports, receives the report request from the base station, or when the measurement result meets the report trigger condition. Specifically, the report information may include: at least one of a single cell measurement result, first reference information and second reference information obtained by single cell measurement and a multicast measurement result obtained by multicast measurement, wherein the first reference information is obtained by the terminal through calculation according to the single cell measurement result and the multicast measurement result; and the second reference information is obtained by the terminal according to the single-cell measurement result, the multicast measurement result and the resource utilization rate of the cell corresponding to the single-cell reference signal. The following illustrates specific contents of the reported information:

the first method comprises the following steps: the terminal reports the single-cell measurement result obtained by performing single-cell measurement and the multicast measurement result obtained by performing multicast measurement to the base station, for example, the terminal reports RSRP, MRSRP, and MRSRQ to the base station.

And the second method comprises the following steps: the terminal calculates and obtains first reference information according to a single cell measurement result obtained by performing single cell measurement and a multicast measurement result obtained by performing multicast measurement, and reports the first reference information, the single cell measurement result and the multicast measurement result to obtain the first reference information, wherein MRSRP represents reference signal receiving power of the multicast broadcast single frequency network reference signal; MRSSI represents received signal strength indication in MBSFN area; the RSRP represents the reference signal received power of the cell-specific reference signal; m is a positive integer, and specifically may be the number of Resource Blocks (RBs) used for measuring the MRSSI in the MBSFN area. The terminal may select M × (MRSRP + RSRP)/MRSSI or M × (MRSRP-RSRP)/MRSSI according to the base station measurement configuration information or terminal predefined information to obtain the first reference information. Obtaining the first reference information through a formula M (MRSRP + RSRP)/MRSSI to obtain the reference signal receiving quality MRSRQ of the MBSFN area after the measured single cell is added in the MBSFN area; in contrast, the reference signal received quality MRSRQ of the MBSFN area after the measured single cell is removed in the MBSFN area can be obtained by the formula M (MRSRP-RSRP)/MRSSI. The terminal obtains MRSRQ (maximum likelihood ratio) of the MBSFN area, namely the first reference information, after the single cell is added or removed through calculation, and reports the first reference information obtained through calculation to the base station, so that the quantization error generated when the base station obtains the first reference information through calculation after receiving the RSRP, the MRSRP and the MRSSI is reduced, and the reporting accuracy is improved.

And the third is that: and the terminal calculates and obtains second reference information according to the single cell measurement result obtained by performing single cell measurement, the multicast measurement result obtained by performing multicast measurement and the resource utilization rate of the cell corresponding to the cell dedicated reference signal, and reports the second reference information, the single cell measurement result and the multicast measurement result to the base station. Specifically, the terminal may obtain the second reference information according to a formula M [ ("MRSRP" + RSRP "/")/MRSSI or M [ ("MRSRP"/")/MRSSI, where MRSRP denotes a reference signal reception power of the multicast broadcast single frequency network reference signal; MRSSI represents the received signal strength indication; RSRP represents the reference signal received power of the cell-specific reference signal; the alfa represents the resource utilization rate of the cell corresponding to the cell dedicated reference signal, the alfa is predefined or configured by the base station, the alfa is greater than 0 and smaller than 1, and M is a positive integer, and specifically, the number of resource blocks used for measuring the MRSSI in the MBSFN area can be used. The terminal may select M (MRSRP + RSRP _ alfa)/MRSSI or M (MRSRP-RSRP _ alfa)/MRSSI to obtain the second reference information according to the base station measurement configuration information or terminal predefined information. And obtaining the second reference information through a formula M (MRSRP + RSRP _ alfa)/MRSSI to obtain the MRSRQ of the MBSFN area after the measured single cell is added in the MBSFN area, and conversely, obtaining the MRSRQ of the MBSFN area after the measured single cell is removed in the MBSFN area through the formula M (MRSRP-RSRP _ alfa)/MRSSI. The terminal reports the first reference information obtained by calculation through the two formulas to the base station, so that the quantization error can be reduced, the reporting accuracy is improved, the resource utilization rate of a single cell corresponding to the CRS is also considered in the calculation of adding or removing the single cell by the terminal, and the accuracy of the MRSRQ of the MBSFN region after cell adjustment is further enhanced.

In a specific implementation process, besides the three kinds of reported information, the reported information can also be a multicast measurement result and first reference information; multicast measurement results and second reference information; the multicast measurement result, the first reference information, the second reference information, and the like, according to the above example of the present invention, the specific content combination of the reported data can be clearly known, and are not illustrated here. No matter which information contained in the reported data can be reported to the base station by adopting a joint reporting mode, wherein the joint reporting mode is used for indicating that parameters for reporting are related, and if the terminal carries out joint reporting on the single-cell measurement result and the multicast measurement result, the single-cell measurement result and the multicast measurement result are related measurement results; and if the terminal obtains a reference result according to the single-cell measurement result and the multicast measurement result, performing combined reporting on the reference result, the single-cell measurement result and the multicast measurement result, wherein the combined reporting is used for indicating that the reference result, the single-cell measurement result and the multicast measurement result are related measurement results. Specifically, the joint reporting may be performed by using a common coding method to report to the base station, for example, encoding RSRP, MRSRP ^ MRSRQ, and then placing the encoded result in a reporting packet to report to the base station; certainly, the measurement result may also be reported to the base station by using a joint coding mode, and the joint coding can reduce the total overhead required for reporting and can effectively indicate that the reported single-cell measurement result and the multicast measurement result are related. In addition, when the terminal reports the measurement result obtained based on the single cell measurement and the multicast measurement result to the base station, the terminal can also report the measurement time information for performing the single cell measurement and the multicast measurement; and/or measurement area information; and/or measuring frequency band information. The measurement time information is used for indicating that a measurement time window for performing single-cell measurement and a measurement time window for performing multicast measurement have correlation; the measurement area information is used for indicating that a measurement area for performing single cell measurement and a measurement area for performing multicast measurement have correlation; the measurement frequency band information is used for indicating that the measurement frequency band for single cell measurement and the measurement frequency band for multicast measurement have correlation. Specifically, the measurement area information may be geographical location information for performing single cell measurement and multicast measurement, or may be cell area information for performing single d, zone measurement and multicast measurement. And the reported single-cell measurement result and the multicast measurement result are related from the measurement time/the measurement area/the measurement frequency band.

The terminal may also report the measurement result in various other manners indicating the correlation between the single-cell measurement result and the multicast measurement result, such as adding a correlation indication identifier in the reported information or coding the reported information according to a specified coding manner, and the like.

When the terminal indicates the correlation between the single cell measurement result and the multicast measurement result in any mode and reports the measurement result, the network control node can effectively judge whether to add a cell to the MBSFN area or to remove a cell from the MBSFN area according to the reported correlation information.

In a specific implementation process, in order to make the terminal more accurate when measuring the received signal strength indication of the multicast broadcast single frequency network, the invention further obtains the received signal strength indication according to at least one specified symbol measurement in a subframe transmitted by the multicast broadcast single frequency network, wherein the specified symbol is a symbol in the subframe data region. The terminal does not measure and obtain the MRSSI according to all the symbols in the subframe transmitted by the MBSFN, but excludes the symbols in the control region with low correlation with the signal receiving strength, and the MRSSI is measured and obtained according to the symbols in the data region, so that the MRSSI obtained by measurement is more accurate.

In a subframe of MBSFN transmission, designated symbols for measuring MRSSI may be all symbols in a data region, for example, a subframe including 12 symbols using an extended Cyclic Prefix (CP), and when the number of symbols in a control region is 1, all symbols numbered in the data region from 1 to 11 are selected as the designated symbols; when the number of the symbols in the control area is 2, all the symbols with the number of the data area being 2-11 are selected as the designated symbols.

In the actual transmission process of the subframe transmitted by the MBSFN, due to the interference of a single cell signal, part of symbols in the subframe can bear a cell-specific reference signal, and these symbols can better represent the real signal reception strength indicating the MRSSI under the condition of the existence of the interference, so that the designated symbol for measuring the MRSSI can also be a symbol bearing the cell-specific reference signal in a subframe data region. Referring to fig. 2, for example, when a single cell employs a conventional CP, a symbol numbered 4/7/8/11 in a data region of a subframe transmitted by the single cell is a symbol carrying CRS, and then the subframe transmitted by MBSFN may correspondingly carry CRS on a symbol numbered 4/7/8/11, so that the symbol numbered 4/7/8/11 is selected as a designated symbol for mrsi measurement.

In addition, when a symbol carrying a cell-specific reference signal overlaps with a symbol used for carrying a multicast service and/or a multicast broadcast single frequency network reference signal in an MBSFN subframe, the MRSSI may also be affected, and therefore, the designated symbol for measuring the MRSSI may also be a symbol used for carrying a multicast service and/or a multicast broadcast single frequency network reference signal which overlaps with a symbol carrying the cell-specific reference signal in a data region. Taking a single cell with a conventional CP as an example, please refer to fig. 3, a symbol bearing MBSFN RS and numbered 6 overlaps with a symbol bearing CRS signals in a data region of an MBSFN subframe; the symbol with the number of 3/4/7 for bearing the multicast service is overlapped with the symbol for bearing the CRS signal; the 9/10 symbols carrying the multicast traffic and the MBSFN RS overlap with the CRS signals, at least one symbol of 3/4/6/7/9/10 may be selected as the designated symbol for the mrsi measurement.

Because the symbols numbered 0-3 in the single cell signal may carry the control signal of the single cell, correspondingly, the symbols numbered 0-3 in the subframe of the MBSFN may overlap or overlap with the symbols carrying the control signal of the single cell due to the interference of the single cell signal, and these symbols are not favorable for the measurement of the MRSSI related to the MBSFN area, therefore, the symbols with the number greater than or equal to 4 are further selected as the symbols for measuring the MRSSI from the designated symbols selected by the above method. Because the measured symbols of the MRSSI do not include any control signal of the single cell outside the MBSFN area, the interference caused by the data area signal of the corresponding single cell in the interference of the single cell included in the MRSSI is ensured, the influence of the load fluctuation of the control signal of the single cell on the adjustment of the MBSFN area and the adjustment of parameters is eliminated, the interference condition of the single cell service transmission on most MBMS service symbols is more accurately reflected, and the network control node is favorable for more accurately adjusting the MBSFN area and/or the MBMS service transmission parameters according to the interference condition.

According to one or more technical schemes in the embodiment of the invention, the terminal carries out single-cell measurement based on the single-cell reference signal and carries out multicast measurement based on the multicast broadcast single-frequency network reference signal; and reporting according to the measurement results obtained by single cell measurement and multicast measurement, so as to realize measurement reporting based on single cell reference signals and multicast broadcast single frequency network reference signals.

Example two

Referring to fig. 4, an embodiment of the present invention provides a measurement feedback method, including:

s401, a terminal obtains a received signal strength indication of a multicast broadcast single frequency network according to at least one appointed symbol measurement in a subframe transmitted by the multicast broadcast single frequency network, wherein the appointed symbol is a symbol in a data area of the subframe;

and S402, the terminal reports according to the received signal strength indication.

In the specific implementation process, a subframe transmitted by the multicast broadcast single frequency network MBSFN includes a control area and a data area, wherein a symbol in the control area is used for carrying a control signal, and a symbol user in the data area carries a multicast service and a reference signal MBSFN RS. In order to enable the terminal to measure the received signal strength indication of the multicast broadcast single frequency network more accurately, the terminal obtains the received signal strength indication MRSSI according to at least one specified symbol measurement in a subframe transmitted by the multicast broadcast single frequency network, wherein the specified symbol is a symbol in a subframe data area. The terminal does not measure and obtain the MRSSI according to all the symbols in the subframe transmitted by the MBSFN, but excludes the symbols in the control region with low correlation with the signal receiving strength, and the MRSSI is measured and obtained according to the symbols in the data region, so that the MRSSI obtained by measurement is more accurate.

In a specific implementation process, in a subframe of MBSFN transmission, the designated symbols used for measuring MRSSI in S401 may be all symbols in a data region; or a symbol carrying a cell-specific reference signal in the data region; the cell-specific reference signal may be a cell-specific reference signal and/or a cell-specific reference signal, and the cell-specific reference signal may be a cell-specific reference signal and/or a cell-specific reference signal. When the designated symbol is a symbol carrying a cell-specific reference signal in the data region, or when the designated symbol is a symbol used for transmitting a multicast service and/or a multicast broadcast single frequency network reference signal in the data region and overlapped with the symbol carrying the cell-specific reference signal, S401 measures to obtain a signal reception intensity indicating that the mrsi is a true signal reception intensity response of the multicast broadcast single frequency network in an actual transmission process in which single cell signal interference exists, thereby further improving the accuracy of the measured mrsi. Since the terminal obtains the received signal strength indication of the multicast broadcast single frequency network according to the at least one designated symbol is described in detail in the first embodiment with reference to fig. 2 and 3, for the brevity of the description, the detailed description is omitted here.

In practical application, symbols numbered 0 to 3 in the single cell signal may carry the control signal of the single cell, and accordingly, symbols numbered 0 to 3 in the subframe of the MBSFN may overlap or overlap with symbols carrying the control signal of the single cell due to interference of the single cell signal, and these symbols are not favorable for measurement of the MRSSI of the MBSFN, so that a symbol numbered 4 or more is further selected as a symbol for measuring the MRSSI from the designated symbols selected by the method. Because the measured symbols of the MRSSI do not include any control signal of the single cell outside the MBSFN area, the interference caused by the data area signal of the corresponding single cell in the single cell interference included in the MRSSI is ensured, the influence of the single cell control signal load fluctuation on the MBSFN area adjustment and parameter adjustment is eliminated, the interference condition of single cell service transmission on most MBMS service symbols is more accurately reflected, and the network control node is favorable for more accurately adjusting the MBSFN area and/or MBMS service transmission parameters according to the interference condition.

After the received signal strength indication mrsi of the multicast broadcast single frequency network is obtained in S401, the terminal continues to execute S402, in which the terminal reports according to the received signal strength indication. Specifically, the terminal may directly report the received signal strength indication to the base station, or may determine the reference signal received quality MRSRQ according to a formula M × MRSRP/mrsi, and then report the signal received signal strength indication and the reference signal received quality MRSRQ to the base station, where MRSRP represents the reference signal received power of the multicast broadcast single frequency network reference signal, and is obtained by measurement when the terminal performs mrsi measurement; m is a positive integer, and may specifically be the number of Resource Blocks (RBs) used for measuring the MRSSI in the multicast broadcast single frequency network MBSFN. Because the more accurate MRSSI is obtained in S401, the accuracy of the MRSRQ determined and reported according to the MRSSI is correspondingly improved.

and then, the base station transmits the reported information to a network control node.

In a specific implementation process, the single-cell measurement result may be a measurement result obtained by the terminal performing measurement based on a single-cell reference signal in a first measurement time window, and the multicast measurement result is a measurement result obtained by the terminal performing measurement based on a multicast broadcast single frequency network reference signal in a second measurement time window, where the first measurement time window is related to the second measurement time window. Specifically, the first measurement time window and the second measurement time window are completely or partially overlapped, or an interval between the first measurement time window and the second measurement time window is smaller than a time threshold.

The specific implementation process of reporting information may be: and the terminal carries out combined reporting on the single cell measurement result and the multicast measurement result, wherein the combined reporting is used for indicating that the single cell measurement result and the multicast measurement result are related measurement results. The reporting information may also be information obtained by the terminal performing joint reporting on a reference result, the single-cell measurement result, and the multicast measurement result, where the reference result is obtained by the terminal through calculation according to the single-cell measurement result and the multicast measurement result, and the joint reporting is used to indicate that the reference result, the single-cell measurement result, and the multicast measurement result are related measurement results.

In practical application, the base station further receives at least one of the following information:

In a specific implementation, the multicast measurement result includes a reference signal reception quality determined by a received signal strength indication of the multicast broadcast single frequency network, the received signal strength indication is obtained by the terminal according to measurement of at least one designated symbol in a subframe of the multicast broadcast single frequency network transmission, wherein the designated symbol is a symbol in the subframe data region. Specifically, the designated symbol is specifically: a symbol in the data region carrying the cell-specific reference signal; or, the specific symbol is a symbol which carries a multicast service and/or a multicast broadcast single frequency network reference signal, and which is overlapped with a symbol which carries the cell-specific reference signal in the data region.

In a specific implementation process, the reporting information specifically includes: and when the single cell measurement result and the multicast measurement result meet reporting triggering conditions, the terminal reports information according to the single cell measurement result and the multicast measurement result. The reporting trigger condition specifically includes at least one of the following conditions:

and a second reference value corresponding to the second reference information is greater than a third threshold value or less than a fourth threshold value, wherein the fourth threshold value is greater than the third threshold value.

In a specific implementation process, before the base station receives the reported information reported by the terminal based on the single cell measurement result and the multicast measurement result, the base station may issue measurement configuration information to the terminal, so that the terminal performs measurement based on the single cell reference signal and measurement based on the multicast broadcast single frequency network reference signal according to the measurement configuration information, wherein the measurement configuration information includes a cell identifier of a cell measured when performing measurement based on the single cell reference signal and a region identifier of the multicast broadcast single frequency network measured when performing measurement based on the multicast broadcast single frequency network reference signal. Correspondingly, the base station issues reporting configuration information to the terminal, so that the terminal reports based on the single-cell measurement result and the multicast measurement result according to the reporting configuration information, wherein the reporting configuration information includes a reporting trigger condition.

In a specific implementation process, the terminal reports to the base station based on the measurement result, and the reported reporting information may include: the terminal comprises a single cell measurement result, at least one of first reference information and second reference information and a multicast measurement result, wherein the single cell measurement result is obtained by the terminal through single cell measurement; the multicast measurement result is obtained by multicast measurement of the terminal; the first reference information is obtained by the terminal according to the single cell measurement result obtained by performing single cell measurement and the multicast measurement result obtained by performing multicast measurement; and the second reference information is obtained by the terminal through calculation according to the single-cell measurement result obtained by performing single-cell measurement, the multicast measurement result obtained by performing multicast measurement and the resource utilization rate of the cell corresponding to the single-cell reference signal. The information is specifically displayed on any one of the following items:

first, single cell measurement and multicast measurement;

second, the first reference information and the multicast measurement result;

third, second reference information and multicast measurement results;

fourthly, multicast measurement results, single cell measurement results and first reference information are obtained;

fifthly, multicast measurement results, single cell measurement results and second reference information;

and sixthly, the multicast measurement result, the single-cell measurement result, the first reference information and the second reference information.

Specifically, the single-cell measurement result obtained by the terminal performing the single-cell measurement includes the reference signal receiving power of the single-cell reference signal, and the multicast measurement result obtained by the terminal performing the multicast measurement includes the reference signal receiving power of the multicast broadcast single-frequency network reference signal and the received signal strength indication of the multicast broadcast single-frequency network. Correspondingly, the measurement results of the terminal based on the single-cell measurement and the multicast measurement include: the reference signal receiving power of the single-cell reference signal, the reference signal receiving power MRSRP of the multicast broadcast single frequency network reference signal and the received signal strength of the multicast broadcast single frequency network indicate that the MRSSL base station can obtain the current reference signal receiving quality of the multicast broadcast single frequency network MBSFN according to the formula M × MRSRP/MRSSI, wherein M is the number of resource blocks used for measuring MRSSI in the MBSFN area.

When the report information reported by the terminal to the base station is the first type of report information, the base station performs reference signal receiving quality calculation after adding the measured cell or performs reference signal receiving quality calculation after removing the measured cell from the multicast broadcast single frequency network based on the first type of report information:

the first calculation method is as follows: the base station may obtain the first reference information according to a formula M × (MRSRP + RSRP)/MRSSI or M × (MRSRP-RSRP)/MRSSI, where MRSRP represents a reference signal received power of the multicast broadcast single frequency network reference signal; MRSSI represents received signal strength indication in MBSFN area; RSRP represents the reference signal received power of a cell-specific reference signal; m is a positive integer, and may specifically be a ratio of the number of Resource Blocks (RB) used for measuring MRSSI in the MBSFN area to the number of Resource blocks used for measuring MRSRP in the MBSFN area. And obtaining the first reference information through a formula M (MRSRP + RSRP)/MRSSI to obtain the reference signal receiving quality MRSRQ of the MBSFN area after the measured single cell is added in the MBSFN area, and conversely, obtaining the reference signal receiving quality MRSRQ of the MBSFN area after the measured single cell is removed in the MBSFN area through the formula M (MRSRP-RSRP)/MRSSI.

The second calculation method is as follows: the base station may obtain the second reference information according to a formula M [ ("MRSRP ] + RSRP [/])/MRSSI or M [ (" MRSRP- ] RSRP [/])/MRSSI, where MRSRP represents a reference signal reception power of the multicast broadcast single frequency network reference signal; MRSSI represents the received signal strength indication; RSRP represents the reference signal received power of the cell-specific reference signal; the alfa represents the resource utilization rate of a cell corresponding to the cell dedicated reference signal, is predefined or configured by a base station, is greater than 0 and less than 1, and is a positive integer, specifically, can be a ratio of the number of resource blocks used for measuring MRSSI in the MBSFN area to the number of resource blocks used for measuring MRSRP in the MBSFN area. Obtaining second reference information through a formula M (MRSRP + RSRP _ alfa)/MRSSI to obtain MRSRQ of the MBSFN area after the measured single cell is added in the MBSFN area; conversely, the MRSRQ of the MBSFN area after the measured single cell is removed in the MBSFN area can be obtained by the formula M (MRSRP-RSRP alfa)/MRSSI.

When the reporting information reported by the terminal to the base station is the second-six types of reporting information, the base station may directly obtain the reference signal reception quality after adding the measured cell or removing the measured cell in the MBSFN area from the reporting information. From the six types of reported information, the base station can obtain not only the current reference signal received power and the current reference signal received quality of the MBSFN area, but also the first reference information and/or the second reference information, that is, the reference signal received quality after adding the single cell to be tested or removing the single cell to be tested in the MBSFN area is obtained, and the coverage condition of the MBSFN area can be reflected more accurately. The measurement and reporting method for the terminal to perform single and zone measurements and multicast wave measurements is the same as that of the first embodiment, and since the first embodiment has been described in detail, the detailed description is omitted here for the sake of brevity.

In the embodiment of the invention, the base station receives and transmits the related information reported by the terminal to the network control node, so that the network control node can obtain the related information of the measurement results of single cell measurement and multicast measurement, thereby quickly optimizing the cell composition of the multimedia broadcast multicast service according to the related information of the measurement results, further solving the technical problem of low cell composition rate of the network control node for optimizing the multimedia broadcast multicast service, and improving the service quality of the multimedia broadcast multicast service.
