Description

Method and device for determining transmission mode

This application claims priority to Chinese Patent Application No. 201410494328.3, entitled "A Method and Apparatus for Determining a Transmission Method", filed on September 24, 2014, the entire contents of which are incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for determining a transmission mode.

Background technique

MBMS (Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast and multicast services for users in a wireless cell. In the LTE (Long Term Evolution) system, MBMS can be provided on both the MBMS-dedicated frequency layer and the frequency layer shared with non-MBMS services. The LTE cell supporting MBMS may be an MBMS dedicated cell or an MBMS/unicast mixed cell. The MBMS service can perform single cell transmission or multi-cell transmission. The multi-cell transmission of MBMS needs to support the MBSFN transmission mode.

The MBSFN (Multimedia Broadcast Multicast Service Single Frequency Network) refers to synchronous transmission in multiple cells at the same frequency at the same time (that is, cells in the same MBSFN area, both of which are Same frequency). Using this transmission method can save frequency resources and improve spectrum utilization. It requires that multiple cells of the same content be sent simultaneously. In this way, the UE (User Equipment) receiver can treat multiple MBSFN cells as one large cell. Therefore, the UE will not only be affected by inter-cell interference transmitted by neighboring cells, but will also benefit from the superposition of signals from multiple MBSFN cells. Both the MBMS dedicated cell and the MBMS/unicast hybrid cell can adopt the MBSFN transmission mode. In addition, the use of advanced UE receiver technology can also solve the problem of time difference of multipath propagation, thereby eliminating intra-cell interference. The diversity effect brought by the multi-cell co-frequency transmission can also solve problems such as blind zone coverage, enhance the reliability of reception, and improve coverage.

In the Small Cell scenario, because the distance between the user and the base station is relatively short, the path loss between the user and the base station is generally considered to be low, so that better channel conditions can be achieved. Supporting higher order modulation is also a possible solution to enhance spectral efficiency. For example, 256QAM (Quadrature Amplitude Modulation) can be used in the Small Cell scene.

3GPP introduces 256QAM PMCH (Physical Multicast Channel), but if the current network environment is not suitable for 256QAM PMCH and 256QAM PMCH is configured for the UE, resources will be wasted; if the current network environment is suitable for 256QAM PMCH, If the UE is configured to perform 256QAM PMCH, the transmission efficiency will be relatively low.

In summary, there is currently no solution for a reasonable configuration of the transmission method.

detailed description

In the embodiment of the present invention, the first network side device determines the quantity information of the UE that is expected to perform different transmission modes, and configures the transmission mode of the MBMS service in the MBSFN area according to the quantity information. The embodiment of the present invention can configure the transmission mode of the MBMS service in the MBSFN area according to the quantity information of the UEs in different transmission modes, thereby implementing a reasonable configuration transmission mode; and further improving system performance.

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a method for determining a sending manner according to Embodiment 1 of the present invention includes:

Step 101: The first network side device determines quantity information of UEs that are expected to perform different transmission modes.

Step 102: The first network side device configures a sending manner of the MBMS service in the MBSFN area according to the quantity information.

In the embodiment of the present invention, the first network side device may be a base station or an MCE (Multi-cell/multicast Coordination Entity), which is separately introduced below.

1. The first network side device is an MCE.

Wherein, if the transmission mode is a modulation mode, the transmission mode is a modulation mode, and the modulation mode is a 256QAM mode;

If the transmission mode is a modulation and coding scheme, the transmission mode is one of an MCS (Modulation and Coding Scheme). The following is a description of the situation.

Case 1: The transmission method is modulation mode.

In the implementation, the MCE notifies the base station when it needs to configure the transmission mode of the MBMS service in the MBSFN area.

After receiving the notification, the base station may notify the UE to report the expected transmission mode. The information about the number of UEs that are expected to perform different transmission modes may be directly determined according to the obtained capability information of the UE, and returned to the MCE.

In an implementation, when determining, according to the capability information of the UE, the base station, when determining the quantity information of the UEs in different transmission modes, the base station may determine, according to the specific service and capability information included in the service information of interest of the UE, that different transmissions are desired. The quantity information of the mode of the UE, such that the determined quantity information granularity is Service, that is, the quantity information of the UEs that perform different transmission modes on the Service for one Service can be determined.

The service information of interest of the UE includes the service of interest of the UE. In the implementation, all services may be regarded as a specific service, and a specific service may be determined from the services of interest of the UE as needed.

The base station can acquire the capability information of the UE and the service information of the UE, such as the UE capability reporting process, and acquire the UE capability process from the MME (Mobility Management Entity); the MBMS Counting mechanism acquires the MBMS Counting mechanism. The business that the UE is interested in.

The base station may also report the capability information of the UE to the MCE as information indicating whether the 256QAM mode is expected to be performed.

The base station may also report the capability information of the UE and the service information of the UE to the MCE as information indicating whether the 256QAM mode is expected to be performed for the specific service.

The MCE determines the number of UEs that are expected to perform different transmission modes in the same manner as the base station described above.

If the base station notifies the UE to report the expected transmission mode, the information may be directly reported to the MCE after receiving the information returned by the UE; or the statistics may be reported to the MCE.

Based on this, determining the number information of UEs that desire to perform different transmission modes includes, but is not limited to, some or all of the following information:

Information indicating whether the 256QAM mode is desired;

The number or proportion of UEs expected to perform 256QAM mode by the base station or application layer network device;

The number or proportion of UEs that are not expected to perform 256QAM mode, as measured by the base station or application layer network device.

If it is based on a specific Service, the number information of the UEs that are determined to perform different transmission modes includes, but is not limited to, some or all of the following information:

Used to indicate whether information about a 256QAM mode is desired for a particular Service;

The number or proportion of UEs that are scheduled by the base station or application layer network device for the 256QAM mode for a particular Service;

The number or proportion of UEs that are not expected to perform the 256QAM mode for a particular Service, as measured by the base station or application layer network device.

When notifying the UE, the base station may notify the UE through an MCCH (Multicast Control Channel) or a DCCH (Dedicated Control Channel).

Based on the information returned by the received base station, the MCE can determine the number information of the UEs that are expected to perform different transmission modes. Further, the MCE can be configured according to the number information of the UEs that are determined to perform different transmission modes.

Specifically, the MCE configures the mode of sending the MBMS service in the MBSFN area to the 256QAM mode when the number of the UEs in the 256QAM mode is determined to meet the configuration requirements.

For example, if the number of UEs that are expected to perform the 256QAM mode is greater than the set threshold, it is determined that the configuration requirements are met; otherwise, it is determined that the configuration requirements are not met.

If the configuration requirements are not met, the MCE can be configured with a modulation mode lower than 256QAM, such as 64QAM.

In the implementation, if the MCE needs to be configured based on a specific service, the MCE notifies the base station that the service ID (identification) corresponding to the specific Service needs to be notified to the base station, and is notified to the UE by the base station.

Correspondingly, for a specific service, when the MCE determines that the quantity information of the 256QAM mode UE meets the configuration requirement for the specific service, the MMS service in the MBSFN area is configured in the 256QAM mode.

For example, if the number of UEs in the 256QAM mode of Service X is greater than a set threshold, it is determined that the configuration requirements are met; otherwise, it is determined that the configuration requirements are not met.

In the implementation, the MCE can also consider the channel quality of the PMCH when configuring the transmission mode.

Specifically, the MCE notifies the base station to let the UE report the channel quality of the PMCH.

When configuring through the UE, you can specify the specific PMCH that needs to be measured; you can also specify it.

If specified, the UE only needs to measure the specified PMCH; if not specified, the UE can measure all the PMCHs that can be measured, and average them and report them.

An implementation manner is that if the UE does not expect to perform the 256QAM mode, the UE may not perform measurement, and thus does not need to report;

If the UE expects to perform the 256QAM mode, and the measured channel quality meets the set threshold, the UE may not report the channel quality;

Correspondingly, the base station forwards the measurement result to the MCE after receiving the measurement result;

If the channel quality of the PMCH reported by the UE is received, the MCE configures the mode of sending the MBMS service in the MBSFN area according to the determined quantity information and the channel quality of the PMCH reported by the UE; or

If the channel quality of the PMCH reported by the UE is not received, the MCE determines that the channel quality of the PMCH of the UE satisfies the condition, and according to the determined quantity information, and the channel quality that satisfies the condition, the MBMS in the MBSFN area The delivery method of the service is configured.

When the measurement configuration is performed for the UE, in addition to the channel information of the PMCH that needs to be measured, the measurement amount that the UE needs to measure may be carried.

Measurements include, but are not limited to, RSRQ (Reference Signal Received Quality), RSRP (Reference Signal Received Power), BLER (Block Error Rate), CQI (Channel Quality Indicator) Quality indication).

When the MCE considers the channel quality configuration transmission mode of the PMCH, when the channel quality of the corresponding PMCH satisfies the condition and determines that the number of UEs that are expected to perform the 256QAM mode meets the configuration requirements, the mode of transmitting the MBMS service in the MBSFN area is configured as 256QAM mode.

That is, the MCE needs to determine whether the measured channel quality meets the requirements, and whether the number or proportion of UEs in the 256QAM mode is required to meet the configuration requirements. If yes, the mode of transmitting the MBMS service in the MBSFN area is configured to be 256QAM. Otherwise, it is determined that the configuration requirements are not met.

In the implementation, if the MCE needs to be configured based on a specific service, the MCE notifies the base station that the service ID corresponding to the specific service needs to be notified to the base station, and is notified to the UE by the base station.

If the capability information of the UE and the specific service included in the service information are used, and the manner of determining the number of UEs of different transmission modes is determined, the MCE notifies the base station that the service ID corresponding to the specific service needs to be notified. After the base station is sent to the base station, the base station can directly report the user capability and the service information of interest to the service ID, or report the statistics to the service ID.

Correspondingly, for a specific service, the MCE satisfies the condition of the channel quality of the corresponding PMCH, and sends the MBMS service in the MBSFN area when the quantity information of the 256QAM mode UE meets the configuration requirement for the specific service. The mode is configured as 256QAM.

That is, the MCE needs to determine whether the measured channel quality meets the requirements, and whether the number or proportion of UEs in the 256QAM mode is required to meet the configuration requirements in a specific Servic, and if yes, the manner in which the MBMS service in the MBSFN area is sent. Configured in 256QAM mode; otherwise, it is determined that the configuration requirements are not met.

The base station in the foregoing case 1 may also be an application layer network device. When the UE is notified, the application layer network device may notify the UE by using application layer signaling. Other processes are the same as those of the base station and will not be described again.

Case 2: The transmission method is modulation coding.

After receiving the notification, the base station may notify the UE to report the expected transmission mode. The information about the number of UEs that are expected to perform different transmission modes may be directly obtained according to the obtained capability information of the UE, and returned to the MCE.

The base station may also report the capability information of the UE to the MCE as information corresponding to a mode for performing the MCS.

The base station may also use the capability information of the UE and the service information of interest of the UE as a representation for the specific The Service expects to perform information corresponding to one mode in the MCS.

Information indicating that one mode in the MCS is desired to be performed;

The number or proportion of UEs in different ways in the MCS that are expected to be counted by the base station or application layer network device.

The information corresponding to one mode in the MCS may be identifier information.

Used to indicate information corresponding to one way in the MCS for a particular Service expectation;

The number or proportion of UEs in different ways in the MCS that are counted by the base station for a particular Service expectation.

When notifying the UE, the base station may notify the UE through the MCCH or the DCCH.

Specifically, when the MCE determines that the quantity information of the UE in one mode of the MCS meets the configuration requirement, the MMS service mode in the MBSFN area is configured to meet the configuration requirement.

For example, if it is desired that the number of UEs in the A mode in the MCS is greater than a set threshold, it is determined that the configuration A mode is satisfied, or the manner in which the UE is most expected in the configuration MCS is determined.

If there are multiple methods that satisfy the number of UEs that are greater than the set threshold, then the largest number can be selected.

Correspondingly, for a specific service, when the MCE determines that the quantity information of the UE in one mode in the MCS meets the configuration requirement for the specific service, the sending manner of the MBMS service in the MBSFN area is configured to be consistent. The way to meet the configuration requirements

For example, if the number of UEs in the A mode in the MCS of the Service X is greater than the set threshold, it is determined that the configuration requirements are met; otherwise, it is determined that the configuration requirements are not met.

An implementation manner is that if the UE does not perform the MCS configuration, the UE may not perform measurement, and thus does not need to report;

If the UE expects to perform the MCS configuration, and the measured channel quality meets the set threshold, the UE may not report the channel quality;

Measurements include, but are not limited to, RSRQ, RSRP, BLER, CQI.

When considering the channel quality configuration transmission mode of the PMCH, the MCE configures the transmission mode of the MBMS service in the MBSFN area when the channel quality of the corresponding PMCH satisfies the condition and the UE that is expected to perform one mode in the MCS meets the configuration requirement. To meet the requirements of meeting the configuration requirements.

That is to say, the MCE needs to determine the number or proportion of UEs of various MCSs that are expected from the UE whose measured channel quality meets the requirements, and select one of the MCS modes corresponding to the required number or proportion.

For example, if the number of UEs of the A mode in the MCS is determined to be greater than a set threshold in determining the number of UEs or the proportions of the various MCSs that are required to be determined from the measured channel quality, the configuration A mode is determined; otherwise, Determine the way in which the most desirable UEs in the MCS are configured.

Correspondingly, for a specific service, the MCE determines, in the UE of the channel quality of the corresponding PMCH, that the quantity information of the UE in one mode in the MCS meets the configuration requirement for the specific service, the MBSFN The sending mode of the MBMS service in the area is configured to meet the configuration requirements.

In the process of configuring the measurement for the UE, if the MCE does not notify the base station to perform measurement reporting, the base station may notify the UE to perform measurement and report the result, and then the base station reports the measurement result to the MCE; the MCE may determine whether to consider the measurement when configuring. result.

The base station in the foregoing case 2 may also be an application layer network device. When the UE is notified, the application layer network device may notify the UE by using application layer signaling. Other processes are the same as those of the base station and will not be described again.

In both cases, the MCE and the base station can be transmitted through the M2AP.

2. The first network side device is a base station.

If the transmission mode is a modulation and coding mode, one of the transmission modes MCS. The following is a description of the situation.

Case 1: The transmission method is modulation mode.

In an implementation, when the base station needs to configure the transmission mode of the MBMS service in the MBSFN area, the base station may notify the UE to report the desired transmission mode. Alternatively, the base station may directly determine, according to the obtained capability information of the UE, different transmissions. The number of UEs in the mode.

The quantity information of the UE that is determined to perform different transmission modes includes information indicating whether the 256QAM mode is desired to be performed.

If it is based on a specific Service, it is determined that the number information of the UEs that desire to perform different transmission modes includes information indicating whether the 256QAM mode is desired for a specific Service.

The base station can determine the quantity information of the UEs that are expected to perform different transmission modes according to the information reported by the UE. Further, the base station can perform configuration according to determining the number of UEs that are expected to perform different transmission modes.

Specifically, the base station configures the mode of transmitting the MBMS service in the MBSFN area to be the 256QAM mode when determining that the quantity information of the UE that is expected to perform the 256QAM mode meets the configuration requirement.

For example, if the number of UEs that are expected to perform the 256QAM mode is greater than a set threshold, it is determined that the configuration requirement is met; otherwise, Make sure the configuration requirements are not met.

If the configuration requirements are not met, the base station can configure a modulation mode lower than 256QAM, such as 64QAM.

In an implementation, if the base station needs to be configured based on a specific service, the base station notifies the UE that the service ID corresponding to the specific service needs to be notified to the base station.

Correspondingly, for a specific service, the base station configures the mode of sending the MBMS service in the MBSFN area to the 256QAM mode when determining that the quantity information of the 256QAM mode UE meets the configuration requirements for the specific service.

In implementation, the base station may also consider the channel quality of the PMCH when configuring the transmission mode.

Specifically, the base station notifies the UE to report the channel quality of the PMCH.

Correspondingly, if receiving the channel quality of the PMCH reported by the UE, the base station configures, according to the determined quantity information, and the channel quality of the PMCH reported by the UE, the manner of sending the MBMS service in the MBSFN area; or ,

If the channel quality of the PMCH reported by the UE is not received, the base station determines that the channel quality of the PMCH of the UE satisfies the condition, and according to the determined quantity information, and the channel quality that satisfies the condition, the MBMS in the MBSFN area The delivery method of the service is configured.

Measurements include, but are not limited to, RSRQ, RSRP, BLER, CQI.

When considering the channel quality configuration transmission mode of the PMCH, the base station configures the transmission mode of the MBMS service in the MBSFN area to be that when the channel quality of the corresponding PMCH satisfies the condition and the number information of the UE that is expected to perform the 256QAM mode meets the configuration requirement. 256QAM mode.

That is, the base station needs to determine whether the measured channel quality meets the requirements, and whether the number or proportion of UEs in the 256QAM mode is required to meet the configuration requirements. If yes, the mode of transmitting the MBMS service in the MBSFN area is configured to be 256QAM. Otherwise, it is determined that the configuration requirements are not met.

In the implementation, if the base station needs to be configured based on a specific service, the MCE notifies the UE that the service ID corresponding to the specific service needs to be notified to the base station.

Correspondingly, for a specific service, when the channel quality of the corresponding PMCH satisfies the condition, and the quantity information of the UE in the 256QAM mode meets the configuration requirement for the specific service, the base station sends the MBMS service in the MBSFN area. The mode is configured as 256QAM.

That is, the base station needs to determine whether the measured channel quality meets the requirements, and whether the number or proportion of UEs in the 256QAM mode is required to meet the configuration requirements in a specific Servic, and if yes, the manner in which the MBMS service in the MBSFN area is transmitted. Configured in 256QAM mode; otherwise, it is determined that the configuration requirements are not met.

Case 2: The transmission method is modulation coding.

The quantity information of the UE that is determined to perform different transmission modes includes information indicating that one mode in the MCS is desired to be performed.

If it is based on a specific Service, determining the number information of the UEs that desire to perform different transmission modes includes information indicating that one mode in the MCS is performed for a specific Service expectation.

The base station can determine the number information of the UEs that are expected to perform different transmission modes according to the information returned by the base station. Further, the base station can perform configuration according to determining the number of UEs that are expected to perform different transmission modes.

Specifically, when the base station determines that the quantity information of the UE in one mode of the MCS meets the configuration requirement, the sending manner of the MBMS service in the MBSFN area is configured to meet the configuration requirement.

For example, if the number of UEs in the A mode in the MCS is greater than the set threshold, it is determined that the configuration A mode is satisfied; otherwise, the manner in which the UE in the MCS is most expected is determined.

Correspondingly, for a specific service, when the base station determines that the quantity information of the UE in one mode in the MCS meets the configuration requirement for the specific service, the sending manner of the MBMS service in the MBSFN area is configured to be consistent. The way to meet the configuration requirements

Measurements include, but are not limited to, RSRQ, RSRP, BLER, CQI.

The UE returns a measurement result to the network side.

When the UE performs measurement, it can perform measurement according to the measurement amount configured on the network side. Measurements include, but are not limited to, RSRQ, RSRP, BLER, CQI.

In the implementation, the transmission mode is a modulation and coding mode, and the modulation mode is a 256QAM mode;

After receiving the notification from the network side that the desired transmission mode is reported, the UE determines the information that needs to be reported, including:

If the network side notifies the service ID corresponding to the specific service, the UE determines to perform the 256QAM mode on the specific service corresponding to the received Service ID, and determines the information to be reported after the measured channel quality of the PMCH meets the condition. Is used to indicate that it is expected to perform 256QAM mode; or,

Is used to indicate the channel quality of the PMCH that is expected to perform 256QAM mode information and measurement; or,

Channel quality of the PMCH.

In the implementation, the precondition for the UE to determine whether to perform the 256QAM mode is that the UE needs to support 256QAM. If the UE supports 256QAM, it can be determined that 256QAM is expected to be performed. It is also possible to further judge whether or not 256QAM is desired based on other factors such as CQI. If the UE does not support 256QAM, it can be directly determined that 256QAM is not expected.

That is, if the UE does not expect to perform the 256QAM mode, the UE may not perform measurement, and thus does not need to report;

If the UE expects to perform the 256QAM mode, and the measured channel quality satisfies the set threshold, the UE may not report the channel quality.

In implementation, the UE measures channel quality of the PMCH, including:

If the notification of the channel quality from the network side for performing the PMCH includes the specified PMCH, the UE performs measurement on the designated PMCH;

If the specified PMCH is not included in the notification of the channel quality of the PMCH from the network side, or the specified PMCH is not present, the UE measures all the PMCHs and performs measurements according to all PMCHs. Get the measurement results that need to be reported.

In an implementation, the UE reports to the network side by using MCCH or DCCH or application layer signaling.

Specifically, if the network side that sends the notification is a base station, and the UE receives the configuration from the network side through the MCCH, the UE reports to the network side through the MCCH;

If the network side that sends the notification is a base station, if the UE receives the configuration from the network side through the DCCH, the UE reports to the network side through the DCCH;

If the network side that sends the notification is an application layer network device, the UE reports to the network side through application layer signaling.

The scheme of the present invention will be described below by way of a few examples. In the following examples, the MCE is used as the initiator. The way the base station acts as the initiator is similar to the MCE, but the MCE is not required to participate.

In the following examples, the 256QAM mode is used as an example. The one in the MCS is similar to the 256QAM mode, and will not be described again.

In the following examples, the base station is taken as an example for description. The scheme for replacing the base station by the application layer network device is similar to the following process, and details are not described herein again.

As shown in FIG. 4, the method for reporting channel quality by using the MCCH signaling in the fourth embodiment of the present invention includes:

Step 1: The MCE sends an MBMS Counting Request message to the base station through the M2AP, where the service ID corresponding to the service to be counted is carried, and the UE is required to report whether the service is expected to perform the 256QAM PMCH indication request, the measurement configuration, and the result report configuration.

The measurement configuration may include a measurement object (eg, a specified PMCH, etc.), and a measurement amount (eg, measurement RSRP, RSRQ, BLER).

Step 2: The base station forwards the MBMS Counting Request message to the UE through the MCCH channel.

Step 3: After receiving the MBMS Counting Request message, the UE supports the 256QAM mode and performs measurement on the specified PMCH according to the configuration information. If the UE is in the idle state, after receiving the MCCH message, it needs to enter the connection state to perform the corresponding operation.

After receiving the MBMS Counting Request message, if the UE does not support the 256QAM mode, the UE does not expect 256QAM.

Step 4: The UE reports, in the MBMS Counting Response message, whether the 256QAM mode is expected to be performed for each Service ID, and reports the measurement result of the PMCH to the base station through the MCCH.

For example, the UE may determine whether to perform the 256QAM mode according to the requirements of the application layer for the QoS quality of the service. If the requirement for the QoS quality of the service is high, it is determined to perform the 256QAM mode; otherwise, it is determined that the 256QAM mode is not expected.

Step 5: The base station forwards the information reported by the UE to the MCE through the M2AP (M2 application protocol).

Here, the base station may also count the number of UEs expected to perform 256QAM mode for each Service ID, and return the result to the MCE, so that the MCE is not required to perform statistics.

Step 6: The MCE determines, according to the statistical Service ID, the number of UEs in the 256QAM mode, and the channel quality distribution of the UE, and determines whether to map the corresponding service to the PMCH channel of the 256QAM, and if yes, passes the existing MBMS scheduling information. The update process performs an update of the MCS; otherwise, the existing configuration is not updated for 256QAM.

As shown in FIG. 5, the method for reporting the MCCH signaling in the fifth embodiment of the present invention and not carrying the channel quality includes:

Step 1: The MCE initiates an MBMS Counting Request message to the base station through the M2AP, where the service ID corresponding to the service to be counted is carried, and the UE needs to report whether the service is expected to perform the 256QAM PMCH indication request and the result report configuration.

Step 3: After receiving the MBMS Counting Request message, if the UE supports the 256QAM mode, the UE does not specify the PMCH on the network side, and the UE performs measurement on all the adapted PMCHs (ie, the PMCH that can receive the data), and obtains an average value.

If the UE is in the idle state, after receiving the MCCH message, it needs to enter the connection state to perform the corresponding operation.

In the implementation, when the UE finds that the quality of the measured PMCH channel satisfies the condition, that is, when the configured measurement event is met, such as exceeding the configured threshold, the measurement result does not need to be carried, and it can be determined that the 256QAM mode is desired.

Step 4: The UE reports in the MBMS Counting Response message whether the 256QAM mode is expected to be performed for each Service ID, and reports the measurement result of the PMCH to the base station through the MCCH.

Step 5: The base station forwards the information reported by the UE to the MCE through the M2AP.

As shown in FIG. 6, the method for reporting the DCCH signaling in the sixth embodiment of the present invention includes:

Step 2: The base station sends an MBMS Counting Request message to the UE by using DCCH signaling. For example, RB reconfiguration message.

In implementation, the base station places the measurement configuration in an MBMS Counting Request message. The measurement configuration may include a measurement object (eg, a specified PMCH, etc.), and a measurement amount (eg, measurement RSRP, RSRQ, BLER).

Step 3: After receiving the MBMS Counting Request message, the UE supports the 256QAM mode and performs measurement on the specified PMCH according to the configuration information. If the PMCH is not specified on the network side, the UE measures all the adapted PMCHs and obtains an average value.

Step 6: The number of UEs in the 256QAM mode that the MCE expects to perform according to the statistical Service ID, and the UE The channel quality distribution determines whether the corresponding Service is mapped to the PMCH channel of 256QAM. If yes, the MCS is updated by the existing MBMS scheduling information update process; otherwise, the existing configuration is not updated for 256QAM.

As shown in FIG. 7, the method for reporting the Counting in the seventh embodiment of the present invention includes:

In practice, a measurement configuration can also be included. The measurement configuration may include a measurement object (eg, a specified PMCH, etc.), and a measurement amount (eg, measurement RSRP, RSRQ, BLER).

Step 2: The base station forwards the MBMS Counting Request message to the UE by using MCCH signaling.

For example, RB (Radio Bearer) reconfigures a message.

Step 5: The base station counts, for each Service ID, the number of UEs that are expected to perform 256QAM mode.

Step 6. The base station returns the statistics result and the measurement result of the UE to the MCE through the MBMS Counting Response message.

The MBMS Counting Response message includes reporting statistics supporting 256QAM, and optionally reporting the measurement result of the specified PMCH.

Step 7: The MCE determines, according to the statistical Service ID, the number of UEs in the 256QAM mode, and the channel quality distribution of the UE, and determines whether to map the corresponding service to the PMCH channel of the 256QAM, and if yes, passes the existing MBMS scheduling information. The update process performs an update of the MCS; otherwise, the existing configuration is not updated for 256QAM.

As shown in FIG. 8, the method for counting UEs by using M2AP according to Embodiment 8 of the present invention includes:

Step 1: The MCE initiates an MBMS Counting Request message to the base station through the M2AP, and carries the service ID corresponding to the service to be counted. The UE needs to report whether the service is expected to perform the 256QAM PMCH indication request, measurement configuration, and result report configuration.

Step 2: The base station counts, according to the obtained UE capability information, the number of UEs that are expected to perform the 256QAM mode.

Here, the number of UEs expected to perform the 256QAM mode may also be counted according to the UE capability information and the service information of interest.

Step 3: The base station reports the number of UEs expected to perform the 256QAM mode by using the MBMS Counting Response message.

Step 4: The MCE performs the number of UEs in the 256QAM mode according to the statistics expected, and determines whether to map the corresponding Service to the PMCH channel of the 256QAM, and if yes, updates the existing MBMS scheduling information. The process performs an update of the MCS; otherwise, the existing configuration is not updated for 256QAM.
