In order to explain the method provided in this embodiment in more detail, in the following, in combination with the above content, the method provided in this embodiment is specifically described by using the following Embodiment 2 to Embodiment 5. For details, refer to the following Embodiment 2 to Embodiment. Five: Example 2

This embodiment provides a method for measuring radio resource management. The method for measuring radio resource management provided in this embodiment is described by using the quantity configuration information in the first embodiment as an example. Referring to FIG. 3, the process of the method provided in this embodiment is specifically as follows:

301: The eNB establishes a new measurement object in the measurement configuration, and the new measurement object includes the measurement Quantity configuration information;

For this step, the CSI-RS-based RRM measurement and reporting, that is, the UE can measure and report the configuration of multiple CSI-RSs, and the measurement configuration information may include one or a combination of the following: CSI-RS antenna port, resource configuration , subframe configuration, physical cell identity, power information, carrier identification, and CSI-RS scrambling ID. Wherein, one carrier identifier may correspond to one carrier frequency.

This embodiment does not limit the specific measurement configuration. In the specific implementation, the measurement configuration used in the CRS-based RRM measurement can be used, and a new measurement object is defined in the measurement configuration for the CRM-RS based RRM measurement. For example: MeasObjectEUTRA-CSI-RS IE, which is independent of CRS-based RRM measurement objects (eg MeasObjectEUTRA, etc.) in existing mechanisms. The configuration of this new measurement object can be as follows:

MeasObjectToAddMod:: = SEQUENCE {

measObj ectldMeasObj ectld,

measObject CHOICE {

measObjectEUTRA MeasObjectEUTRA,

measObjectUTRA MeasObj ectUTRA,

measObjectGERAN MeasObj ectGERAN,

measObjectCDMA2000 MeasObjectCDMA200, measObj ectEUTRA-csi-rs MeasObj ectEUTRA-CSI-RS //Measurement object definition for CSI-RS

Further, the newly defined measurement object in the measurement configuration needs to contain at least the following information:

1. The carrier frequency corresponding to the measurement object

2, measuring bandwidth

3, frequency offset

4. CSI-RS configuration information

Ie: MeasObjectEUTRA-CSI-RS:: = SEQUENCE {

carrierFreq ARFCN-ValueEUTRA,

allowedMeasBandwidth AllowedMeasBandwidth,

offsetFreq Q-offsetRange DEFAULT dBO, csi-rsConfigList SEQUENCE(SIZE(1..maxCSI-RS))

CSI-RSConfig

Where carrierFreq is the carrier frequency, allowedMeasBandwidth is the measurement bandwidth, offsetFreq is the frequency offset, and csi-rsConfigList is the measurement configuration information of CSI-RS. The CSI-RSConfig IE needs to contain at least one or more of the following elements:

1. Antenna port configuration for CSI-RS transmission

2. Resource configuration of CSI-RS transmission

3. Subframe configuration for CSI-RS transmission

Ie: CSI-RSConfig ::= SEQUENCE {

csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8}, resourceConfig NTEGER (0..31),

subframeConfig INTEGER (0..154),

Optionally, in addition to the manner of notifying the UE to measure the configuration information by using the manner of establishing a new measurement object, the manner of adding the measurement configuration information of the CSI-RS to the original measurement object in the measurement configuration may be used. The way, the measurement object is as follows:

MeasObjectEUTRA ::= SEQUENCE {

carrierFreq ARFCN-ValueEUTRA,

allowedMeasBandwidth AllowedMeasBandwidth,

presenceAnteenaPortl PresenceAntennaPortl ,

[[measCycleSCell-rlO MeasCycleSCell-rlO OPTIONAL -Need ON

]]

csi-rsConfigList SEQUENCE(SIZE(1..maxCSI-RS)) OF CSI-RSConfig OPTIONAL For the definition of CSI-RSConfig lE, refer to the above content, and details are not described herein.

302: The eNB sends a measurement configuration including a new measurement object to the UE.

For this step, the embodiment does not limit the manner in which the eNB sends the measurement configuration, and can refer to the transmission mode used in the existing CRS-based RRM measurement.

303: The UE receives the measurement configuration, obtains measurement configuration information according to the measurement configuration, and performs corresponding measurement according to the measurement configuration information.

The embodiment does not limit the manner in which the UE receives the measurement configuration, and may refer to the receiving mode used in the existing CRS-based RRM measurement. In addition, since the eNB establishes a new measurement object in the measurement configuration, and the new measurement object includes the measurement configuration information, after receiving the measurement configuration, the UE can obtain the measurement configuration information by parsing the measurement configuration, thereby The RRM measurement is performed based on the acquired measurement configuration information. The manner in which the UE performs the RRM measurement according to the obtained measurement configuration information is also not specifically limited in this embodiment.

So far, the RSI measurement process based on the CSI-RS ends, in order to enable the eNB to learn the channel quality between each network node and the UE, thereby determining the accessory node selection of the UE or the coordinated transmission of the network side node, after the UE performs the RRM measurement, The method provided by the embodiment may further include a process of subsequently reporting the measurement result, as described in step 304 below.

304: The UE reports the measurement configuration information and the corresponding measurement result to the eNB.

In this step, when the UE reports the measurement result to the eNB, in order for the eNB to determine which measurement configuration information is reported by the UE, the UE needs to report the measurement configuration information corresponding to the measurement result when reporting the measurement result.

In addition, in order to reduce the resources occupied by the UE when reporting the measurement result, as a preferred solution, the method provided by the embodiment further supports the method of measuring the configuration information corresponding to the measurement configuration information, that is, the UE reports the measurement configuration information to the eNB. The identification and corresponding measurement results. For the reporting mode, the eNB only sends the measurement configuration information to the UE, and the identifier corresponding to the configuration information is measured, that is, the CSI-RS ID does not need to be configured or transmitted by the eNB, and the CSI-RS ID may be the eNB and the UE. After the rule is generated, the UE obtains the CSI-RS ID according to the measurement configuration information, and then reports the CSI-RS ID and the corresponding measurement result to the eNB. For example, the CSI-RS ID is an index of all CSI-RS configurations sent by the eNB, or the UEs are identified according to the order of CSI-RS configurations issued by the eNB, that is, an assignment ID (for example, 32 in total, according to ID is numbered from 0 to 31), then When the UE reports, if it is agreed to report 8, the CSI-RS ID is carried in the 8 reported.

In order to enable the UE to report the CSI-RS ID instead of the measurement configuration information, the method provided by this embodiment supports other methods, for example, the eNB is in the direction, except that the CSI-RS ID is pre-agreed by the eNB and the UE in the foregoing manner. Before the UE sends the measurement configuration information, the UE may first send the identifier corresponding to the measurement configuration information to the UE by using the system broadcast message or the RRC message, and then the UE broadcasts the message or the RRC according to the measurement configuration information sent by the eNB. The identifier corresponding to the measurement configuration information is obtained in the message, and then the identifier corresponding to the measurement configuration information and the corresponding measurement result are reported.

The UE may perform the CSI-RS measurement result report when the identifier corresponding to the measurement configuration information and the corresponding measurement result are reported in the above manner. And if the UE needs to report the CSI-RS based measurement result, the MeasResultList-CSI-RS IE can be newly defined in the existing measurement report message.

MeasResult-CSI-RS:: = SEQUENCE {

Csi-rsld CSI-RSId,

rsrpResult RSRP-Range,

rsrqResult RSRQ-Range Optionally, in addition to the above method of reporting the CSI-RS measurement result based on the existing measurement report message, a new method for measuring the report message may be defined to report the CSI-RS measurement. As a result, for this approach, the newly defined measurement report message is as follows:

MeasurementReport-CSI-RS ::= SEQUENCE {

measurementReport-csi-rs MeasurementResults-CSI-RS, nonCriticalExtension SEQUENCE {} OPTIONAL }

MeasurementResults-CSI-RS :: = SEQUENCE {

Measld Measld,

measResultList-csi-rs MeasResultList-CSI-RS Among them, MeasResultList-CSI-RS IE has the same definition as above, and is no longer cumbersome here. As can be seen from the above, different frequencies correspond to different measld. That is to say, all CSI-RS measurement results on different frequencies can be reported by different MeasResults or different MeasurementReport-CSI-RS messages. The reported CSI-RS measurement results are independent of Cell and only correspond to frequency. Similarly, the reported CSI-RS measurement results can also be related to Cell, which is no longer cumbersome.

The RRM measurement procedure in the case where the measurement configuration information of the CSI-RS and the Cell (cell) are independent of each other is discussed above, and the measurement configuration information of the CSI-RS is associated with the Cell, and the measurement configuration information of the CSI-RS needs to be related to the PCI. (Physical Cell Identifier) is bound, for example: Add PCI parameters in the above CSI-RSConfig lE definition, as follows:

Ie: CSI-RSConfig ::= SEQUENCE {

Csi-rsld INTEGER(1..maxCSI-RS), Physicalcellld PhysCellld OPTIONAL, csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8} resourceConfig BIT STRING NTEGER (0..31),

subframeConfig INTEGER (0..154),

In addition, in the existing CRS-based RRM measurement, the network side can configure different measurement parameters for different measurement cells, so that the UE can preferentially switch to these designated cells. The method provided by this embodiment may perform CSI-RS configuration or port (port) or node preference according to the configuration of the CSI-RS after the introduction of the CSI-RS, for the same frequency, PCI same/different node, for example. : By setting the IndividualOffset.

In the specific implementation, the network side needs to set different offset parameters for different nodes. That is to say, in the measurement configuration, the IndividualOffset parameter can be bound to the CSI-RS ID parameter, for example: CSI-RSConfig IE definition adds IndividualOffset The parameters are as follows:

Ie: CSI-RSConfig ::= SEQUENCE {

Csi-rsld INTEGER(1..maxCSI-RS),

csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8}, resourceConfig BIT STRING NTEGER (0..31),

subframeConfig INTEGER (0..154),

IndividualOffset Q-OffsetRange OPTIONAL

In addition, the RRM measurements involved in this embodiment and subsequent embodiments include, but are not limited to, RSRQ (Reference Signal Received Quality) measurement and/or RSRP (Reference Signal Received Power) measurement. The measurement configuration information related to the embodiment and the subsequent embodiments may include CSI-RS configuration information used in the cell in addition to the CSI-RS configuration information used in the local cell, and therefore, When determining the measurement configuration information, the network side device needs to obtain the measurement configuration information of the neighboring cell through the X2 interface. In the specific implementation, the CSI-RS configuration information used in the neighboring cell can be obtained through the ENB CONFIGURATION UPDATE message on the X2 interface. That is, the IE needs to be newly defined in the ENB CONFIGURATION UPDATE message. The configuration information of the CSI-RS is transmitted, and the CSI-RS configuration information of the zero power transmission may also be included. As follows:.

Among them, maxnoofCSI-RS IE is defined as follows:

The method provided in this embodiment introduces a CSI-RS-based RRM measurement, and even if the carrier frequency and the PCI of the Macro and the RRH are the same, it is considered to be the same cell for the UE, but the Macro and the RRH use different CSI-RSs. In the configuration, the UE performs measurement and reporting according to the configuration of the CSI-RS, so that the network side device can obtain the channel quality between each network node and the UE, thereby determining the auxiliary node selection of the UE or the coordinated transmission of the network side node. Embodiment 3

This embodiment provides a method for measuring radio resource management. In combination with the content of the foregoing embodiment 1, for convenience of description, in this embodiment, the UE does not pre-acquire or pre-store measurement configuration information, and the eNB sends a system broadcast to the UE. The method for notifying the measurement information and the identifier corresponding to the measurement configuration information to the UE is used as an example to describe the measurement method of the radio resource management provided in this embodiment. Referring to FIG. 4, the process of the method provided in this embodiment is specifically as follows:

401: The eNB sends the identifier corresponding to the measurement configuration information and the measurement configuration information to the UE by using a system broadcast message.

For this step, the RSI measurement and reporting based on the CSI-RS, that is, the UE can measure and report the configuration of multiple CSI-RSs, and the measurement configuration information may include one or a combination of the following: CSI-RS Antenna port, resource configuration, subframe configuration, physical cell identity, power information, carrier identification, and CSI-RS scrambling ID. The carrier identifier may correspond to a carrier frequency. In order to enable the UE to report the measurement result, the measurement configuration information is not required to be reported, thereby saving resources. The method provided in this embodiment takes the configuration information of the CSI-RS measurement. The elements are combined in a certain order to obtain a configuration index of the CSI-RS, that is, a manner of measuring the CSI-RS ID corresponding to the configuration information. Each CSI-RS ID corresponds to a measurement configuration information of a CSI-RS, that is, a combination corresponding to a CSI-RS configuration element.

In determining the CSI-RS ID, a preferred mode is that the measurement configuration information of the CSI-RS includes only three elements: the number of antenna ports (AP), resource configuration (RC), and subframe configuration (SC). There are several situations for these three elements:

Case 1 : number of antenna ports AP, resource configuration RC, subframe configuration SC;

Case 2: Fixed AP, the configuration of different CSI-RS is only different for RC and SC;

Case 3: Fixed SC, different CSI-RS configurations are only different for AP and RC;

Case 4: Fixed AP and SC. The configuration of different CSI-RS is only different for RC.

For each case, the maximum value of the CSI-RS ID, maxCSI-RS, can be defined. The following is an example of case 4, and FDD. The number of antenna ports is fixed, for example: 2 antenna ports, the measurement subframe period SC is fixed (for example, 10 ms). In the normal CP (cyclic prefix) scenario, the value of maxCSI-RS is 32*10=320, as shown in the following table. 1 shows:

Among them, CSI-RSConfig IE needs to include one or more of the following elements:

1, CSI-RS configuration index

2. Antenna port configuration for CSI-RS transmission

3. Resource configuration of CSI-RS transmission

4. Subframe configuration for CSI-RS transmission

Csi-rsld INTEGER(1..maxCSI-RS),

subframeConfig INTEGER (0..154),

Csi-rsld configures an index for the CSI-RS, that is, the identifier corresponding to the measurement configuration information.

402: The UE receives the system broadcast message, and obtains the identifier corresponding to the measurement configuration information and the measurement configuration information according to the system broadcast message.

For this step, the embodiment does not limit the manner in which the UE receives the system broadcast message, The system broadcast message includes an identifier corresponding to the measurement configuration information and the measurement configuration information, and after receiving the system broadcast message, the UE may obtain the measurement configuration information and the identifier corresponding to the measurement configuration information according to the system broadcast message.

403: The eNB adds an identifier corresponding to the measurement configuration information to the original measurement object in the measurement configuration, and sends the measurement configuration to the UE.

For this step, since the UE has learned the measurement configuration information through the system broadcast message, when the eNB performs the CSI-RS RRM measurement configuration on the UE, only the identifier corresponding to the measurement configuration information needs to be specified. The UE4 obtains corresponding measurement configuration information according to the identifier corresponding to the measurement configuration information, so as to perform corresponding CSI-RS measurement. When the identifier corresponding to the measurement configuration information is sent to the UE, the embodiment adds the identifier corresponding to the measurement configuration information to the original measurement object of the measurement configuration, and sends the measurement configuration to the UE. After the measurement object increases the identifier corresponding to the measurement configuration information, it looks like this:

That is, if a bit is set to 0, the network side requires the UE to perform RRM measurement on the CSI-RS configuration corresponding to the index value; otherwise, the UE does not need to perform RRM measurement on the CSI-RS configuration corresponding to the index value.

Optionally, the method provided in this embodiment further supports establishing a new measurement object in the measurement configuration, except that the identifier corresponding to the measurement configuration information is added to the original measurement object in the measurement configuration to notify the UE. The new measurement object includes an identifier corresponding to the measurement configuration information. As with the existing CRS-based RRM measurement method, one measurement object corresponds to one carrier frequency. After the CSI-RS measurement is introduced, there may be multiple CSI-RS measurement configuration information on the carrier frequency, and different CSI-RS measurement configuration information corresponds to one configuration index value. According to the description of the foregoing step 401, since the eNB has sent the identifier corresponding to the measurement configuration information and the measurement configuration information to the UE through the system broadcast message, the eNB only needs to notify the UE of the CSI-RS ID parameter, and the new measurement object, At a minimum, you need to include the following information:

1. The carrier frequency corresponding to the measurement object
