Description

Measuring method and user equipment

The present application claims priority to Chinese Patent Application No. 201010004207.8, entitled "Measuring Method and User Equipment", filed on January 14, 2010, the entire contents of which are hereby incorporated by reference. Technical field

A method and a user equipment _t background art relates to communication technologies, and in particular relates to a measuring embodiment of the present invention

Long Term Evolution (LTE) system is a single carrier system. One physical cell consists of a single carrier with a maximum bandwidth of 20M. In order to guarantee high-bandwidth and high-speed service quality, carrier aggregation technology is introduced into advanced long-term evolution (Long Term)

Evolution-Advanced; hereinafter referred to as: LTE-A) system. Carrier aggregation refers to the aggregation of two or more consecutive or non-contiguous component carriers while providing the user with a wireless transmission bearer. In the case of carrier aggregation, on the one hand, one physical cell may include multiple aggregated component carriers, and on the other hand, multiple component carriers may be configured on the network side to one user equipment (User Equipment; hereinafter referred to as UE). Used for sending and receiving data.

1 is a schematic diagram of a carrier aggregation cell in the prior art. As shown in FIG. 1 , carriers in the same horizontal line in carrier aggregation cell 1 and carrier aggregation cell 2 are in the same frequency layer; carrier aggregation cell 1 and carrier aggregation cell 2 Two carriers at the same frequency layer have different physical cell identities. The carriers in different frequency layers of the carrier aggregation cell 1 are component carriers of the carrier aggregation cell 1; the component carriers of the carrier layer 1 and the frequency layer 2 in the carrier aggregation cell 1 are component carriers allocated to the UE, that is, the service carriers of the UE, The set of service carriers constitutes a serving cell; the component carriers in the carrier aggregation cell 1 at the frequency layer 3, the frequency layer 4, and the frequency layer 5 are component carriers not allocated to the UE. The carriers in different frequency layers of the carrier aggregation cell 2 are component carriers of the carrier aggregation cell 2, the component carriers of the carrier aggregation cell 2 are adjacent carriers of the serving carrier of the UE, and the carrier aggregation cell 2 is the neighboring cell of the carrier aggregation cell 1. . The traditional mobility management means that the network side switches the UE in the connected state to the appropriate target cell in time through the measurement control and the measurement reporting of the UE. This can also be called horizontal handover. In the case of carrier aggregation, the network side The UE is configured to be a suitable component carrier in the same carrier aggregation cell, and can be referred to as component carrier management or vertical handover.

In order to manage mobility in the connected state, each wireless network protocol defines its own measurement process. In the existing measurement protocol of LTE, each measurement object corresponds to one frequency layer, that is, each frequency layer can only be configured with one measurement object. The UE performs cell measurement and evaluation on the specified frequency layer, and reports the measurement report according to the configured measurement event.

In the prior art, the component carriers that are not configured for the UE in the carrier aggregation cell where the UE is located are treated the same as the component carriers in the other carrier aggregation cell, and the same trigger event is configured on the same frequency layer, so that the same reporting criterion is applied. The above two types of component carriers may further cause the UE to report the measurement report frequently to the component carriers that are not configured for the UE in the carrier aggregation cell where the UE is located, which causes waste of the air interface resources for sending the measurement report.

The first threshold, the second threshold, the third threshold, and the fourth threshold may be preset in a specific implementation, and the first threshold, the second threshold, the third threshold, and the first embodiment of the present invention The specific values of the four thresholds are not limited.

The embodiment of the present invention provides a measurement method. As shown in FIG. 2, FIG. 2 is a flowchart of an embodiment of a measurement method according to the present invention. The embodiment may include:

Step 201: Receive indication information sent by the network side device, where the indication information indicates a component carrier that is not configured to the user equipment in the carrier aggregation cell of the user equipment.

In an implementation manner of the embodiment of the present invention, the indication information sent by the receiving network side device may be: the user equipment receives the measurement configuration parameter that is sent by the network side device by using the RRC signaling, where the measurement configuration parameter includes the measurement object, and the measurement object The new information element carries the first indication information, where the first indication information indicates a component carrier that is not configured to the user equipment on the frequency layer corresponding to the measurement object in the carrier aggregation cell where the user equipment is located.

In the foregoing implementation manner, the network side device adds a new cell to the measurement object of the measurement configuration parameter that is sent to the user equipment, and the newly added cell indicates that the user equipment is located in the carrier aggregation cell, and corresponds to the measurement object. The component carrier of the user equipment is not configured on the frequency layer. Specifically, when the language of Abstract Syntax Notation One (hereinafter referred to as ASN.1) is adopted, the above measurement object may be:

MeasObjectEUTRA:: = SEQUENCE {

CarrierFreq ARFCN-ValueEUTRA, CandidateServingCell PhysCellld}

In another implementation manner of the embodiment of the present invention, the indication information sent by the receiving network side device may be: the user equipment receives the measurement configuration parameter that is sent by the network side device by using the RRC signaling, where the measurement configuration parameter includes indication information, and the indication The information indicates, in the form of a list, component carriers that are not configured for the user equipment in the carrier aggregation cell where the user equipment is located. Specifically, when the ASN.1 language is adopted, the measurement configuration parameter may be:

MeasConfig ::=SEQUENCE {

― Non configured cells

Non-configured cells: :=SEQUENCE (SIZE (1..maxNon-configuredcells)) OF {PhysCellld PhysCellld,

carrierFreq CarrierFreqEUTRA}

― Measurement objects

measObjectToRemoveList MeasObj ectToRemo veList OPTIONAL, ― Need ON

measObjectToAddModList MeasObj ectToAddModList OPTIONAL, -

Need ON

...... }

In a further implementation manner of the embodiment of the present invention, the indication information sent by the receiving network device may be: configuring a component carrier for the user equipment on the network side device, or reconfiguring the component carrier occupied by the user equipment by the network side device The user equipment receives the indication information sent by the network side device; that is, when the network side device configures the component carrier for the user equipment, or the network side device reconfigures the component carrier occupied by the user equipment, the network side device passes the indication. The information indicates not only the component carrier configured for the user equipment but also the component carrier that is not configured for the user equipment in the carrier aggregation cell where the user equipment is located. Specifically, the indication information includes the component carrier configured for the user equipment and the user. The frequency and physical cell identifier of the component carrier that is not configured for the user equipment in the carrier aggregation cell where the device is located. In a further implementation manner of the embodiment of the present invention, the receiving the information sent by the network side device may be: the user equipment receives the broadcast message sent by the network side device, where the broadcast message carries the indication information, where the indication information indicates the carrier where the user equipment is located. A component carrier that is not configured for the user equipment in the aggregation cell.

Step 202: Perform measurement evaluation and measurement report reporting on the component carrier that is not configured to the user equipment, and indicate that the component carrier that is not configured to the user equipment is measured and evaluated and reported in the measurement report. It is different from the method of performing measurement evaluation and measurement report reporting on the neighboring cell of the carrier aggregation cell where the user equipment is located.

In an implementation manner of the embodiment of the present invention, the user equipment may be used as a user component of the component carrier that is configured in the carrier aggregation cell of the user equipment, and the component carrier that is not configured to the user equipment that is indicated by the indication information. The service carrier of the device is reported for measurement evaluation and measurement report. Specifically, the user equipment may be configured according to the configured measurement event of the service carrier, for example, an A1 event or an A2 event, and the component carrier allocated to the user equipment in the carrier aggregation cell where the user equipment is located is not configured to be indicated by the indication information. The signal quality of the component carrier of the user equipment is reported to the user equipment, and the user equipment may be configured to the member carrier of the user equipment in the carrier aggregation cell where the user equipment is located, and the user equipment is not configured to be indicated by the indication information. The component carrier is used as a reference carrier, and according to the configured measurement event of the adjacent carrier, for example: A3 event or A5 event, the signal quality of the adjacent carrier in the same frequency layer as the reference carrier is measured by referring to the reference carrier. The assessment and measurement report is reported.

In this implementation, for an A1 event or an A2 event, a member carrier that is not configured for the user equipment is treated as a service carrier of the user equipment, as is the member carrier configured for the user equipment. The user equipment can trigger the measurement report to report when the signal quality meets the trigger condition of the A1 event or the A2 event according to the measurement configuration parameters of the network side device.

For the A3 event or the A5 event, the user equipment that is not configured to the user equipment is also regarded as the service carrier. Therefore, the component carrier that is not configured for the user equipment in the carrier aggregation cell where the user equipment is located is configured and configured to the user equipment. The component carriers can be used as reference carriers, and the user equipment can The measurement and evaluation report and the measurement report are reported on the signal quality of the adjacent carrier in the same frequency layer as the reference carrier according to the configured A3 event or the A5 event. At this time, the comparison model of the measurement events of the adjacent carriers can be as shown in FIG. 3. FIG. 3 is a schematic diagram of an embodiment of a comparison model of measurement events of adjacent carriers according to the present invention.

In this implementation manner, the network side device may configure the first threshold of the A1 event on the component carrier that is not in the carrier aggregation cell where the user equipment is located, and the component carrier that is not configured to the user equipment and the component carrier that is configured to the user equipment. Or the second threshold of the A2 event, which is used to control the reporting of the measurement report on the component carrier of the user equipment and the component carrier configured to the user equipment in the carrier aggregation cell where the user equipment is located; The A4 event or the A5 event, because the component carrier that is not configured to the user equipment in the carrier aggregation cell where the user equipment is located is used as the service carrier, the measurement report of the component carrier that is not configured to the user equipment is not triggered, which saves the use. The air interface resource for sending measurement reports.

In another implementation manner of the embodiment of the present invention, the user equipment may aggregate the carrier where the user equipment is located according to the configured measurement event on the frequency layer corresponding to the component carrier that is not configured to the user equipment that is indicated by the indication information. In the cell, the signal quality of the component carrier other than the component carrier that is not configured to the user equipment is reported to be measured and evaluated by the neighboring cell, that is, corresponding to the component carrier that is not configured for the user equipment. The user equipment ignores the signal quality of the component carrier that is not configured to the user equipment indicated by the indication information when the measurement and evaluation report of the neighboring cell is performed on the frequency layer; that is, the user equipment can measure the carrier where the user equipment is located. The signal quality of the component carrier of the user equipment is not configured in the aggregation cell, but when the measurement and evaluation of the neighboring cell and the measurement report are reported, only the signal quality of the component carrier configured to the user equipment is considered, regardless of whether the above is not configured. Signal quality of the component carrier of the user equipment; of course, the user equipment The signal quality of the component carrier that is not configured to the user equipment in the carrier aggregation cell where the user equipment is located may not be measured, so that when the measurement and evaluation of the neighboring cell and the measurement report are reported, the user equipment does not consider the foregoing unconfigured to the user. The signal quality of the component carrier of the device. In a further implementation manner of the embodiment of the present invention, the user equipment may perform the carrier of the user equipment according to the configured measurement event on the frequency layer corresponding to the component carrier that is not configured to the user equipment that is indicated by the indication information. In the aggregated cell, the signal quality of the component carrier other than the component carrier that is not configured to the user equipment is measured and evaluated by the neighboring cell, that is, the user equipment may correspond to the component carrier that is not configured for the user equipment. When the measurement and evaluation of the neighboring cell is performed on the frequency layer, the signal quality of the component carrier not allocated to the user equipment indicated by the indication information is ignored; but the measurement of the frequency layer corresponding to the component carrier not configured for the user equipment is reported. At the time of reporting, the user equipment may report the signal quality of the component carrier other than the component carrier that is not configured to the user equipment, and the indication of the indication information is not configured to the user. The signal quality of the component carrier of the device; that is, the user equipment can measure the signal The signal quality of the component carrier that is not configured for the user equipment in the carrier aggregation cell where the user equipment is located. The user equipment does not consider the signal quality of the component carrier that is not configured to the user equipment when performing measurement and evaluation of the neighboring cell. When the measurement report of the neighboring cell on the frequency layer corresponding to the measurement object configured by the network side device is reported, the signal quality of the component carrier that is not configured to the user equipment may be reported to the network side device.

In a further implementation manner of the embodiment of the present invention, the user equipment may use the component carrier that is not configured to the user equipment as the measurement target, or the carrier where the user equipment is located in the aggregation cell, except a component carrier other than the component carrier that is not configured to the user equipment and a component carrier that is not configured to the user equipment indicated by the indication information is used as a measurement object, and the measurement object is measured and evaluated according to the configured measurement event. The measurement report is reported; the measurement event of the configuration may be for component carrier management, for example: the measurement event of the configuration may be an A2 event. That is, the network side device may use the component carrier that is not configured to the user equipment in the carrier aggregation cell where the user equipment is located, or all component carriers of the carrier aggregation cell where the user equipment is located as a measurement object, and configure the measurement object for the measurement object. A unified measurement event for component carrier management, such as: A2 event, and then inform the measurement event by measuring configuration parameters The user equipment, so that the user equipment can perform measurement evaluation and measurement on the component carrier that is not configured for the user equipment in the carrier aggregation cell where the user equipment is located, or all component carriers of the carrier aggregation cell where the user equipment is located, according to the configured measurement event. Report reporting; enabling measurements to better serve component carrier management.

Taking the A2 event as an example, if the user equipment performs measurement evaluation on the component carrier that is not configured for the user equipment in the carrier aggregation cell where the user equipment is located according to the A2 event, or all component carriers of the carrier aggregation cell where the user equipment is located, The component carrier of the user equipment is not configured, or the signal quality of at least one component carrier of all component carriers of the carrier aggregation cell where the user equipment is located is lower than a preset second threshold, and the user equipment is to the network side. The device reports the measurement report, and notifies the network side device of the signal quality of the at least one component carrier, so that the network side device does not consider configuring the at least one component carrier to the user equipment when performing component carrier management.

In the foregoing embodiment, the user equipment may identify, according to the received indication information, a component carrier that is not configured to the user equipment in the carrier aggregation cell where the user equipment is located, and may not be configured in the carrier aggregation cell where the user equipment is located in the measurement process. The carrier of the user equipment is treated differently, and the reporting of the measurement report of the component carrier that is not configured to the user equipment in the same carrier aggregation cell is reduced, which saves the air interface resource for sending the measurement report.

A person skilled in the art can understand that all or part of the steps of implementing the above method embodiments may be completed by using hardware related to the program instructions. The foregoing program may be stored in a computer readable storage medium, and the program is executed when executed. The foregoing steps include the steps of the foregoing method embodiments; and the foregoing storage medium includes: a medium that can store program codes, such as a ROM, a RAM, a magnetic disk, or an optical disk.
