1 is a flow chart of a measurement method of one embodiment of the present invention. The method of Figure 1 is performed by a UE.

The UE obtains the subframe configuration information of the interfering cell, and the subframe configuration information is used to indicate the subframe configuration of each subframe included in a time period, where the subframe configuration includes an uplink subframe, a downlink subframe, and a flexible subframe.

102. The UE determines, according to the subframe configuration information, a subframe configuration of the second subframe of the interfering cell corresponding to the first subframe of the cell to be tested.

103. When the subframe configuration of the second subframe of the interfering cell determines that the time condition is met, the UE performs a measurement operation on the cell to be tested in the first subframe.

In the embodiment of the present invention, the UE acquires the subframe configuration information, where the subframe configuration information is used to indicate the subframe configuration of each subframe included in a time period, and the subframe configuration includes an uplink subframe, a downlink subframe, and a flexible subframe. And determining, by the subframe configuration information, a subframe configuration of the second subframe of the interfering cell corresponding to the first subframe of the cell to be tested, when the subframe configuration of the second subframe of the interfering cell determines that the time condition is met, The measurement operation is performed on the cell to be tested in the first subframe, so that the UE selects a suitable measurement time to measure the cell to be tested, so as to avoid the subframe configuration of the interfering cell affecting the measurement of the UE, and improve the accuracy of the measurement.

The cell to be measured measured by the UE may be a serving cell, or may be a neighboring cell of the serving cell of the UE, and the interfering cell may be adjacent to the measured cell to be tested, and the number of the interfering cell may be one or more, The embodiment of the invention is not limited thereto.

It should be noted that a flexible subframe means that the subframe can be configured as a UL (Uplink) subframe or a DL (downlink) subframe. That is to say, in a certain period of time, the flexible subframe can be configured as a DL subframe and configured as a UL subframe in another period of time.

It should also be noted that one time period may be one or more transmission time intervals, one or more radio frames, or other The time period of the length. The embodiment of the invention does not limit this.

Optionally, as an embodiment, in step 101, the UE may obtain subframe configuration information from the base station, specifically, when the UE is in the connected state, the UE reads the SIB (System Information Block, system message) of the cell to be tested. The RRC (Radio Resource Control) connection reconfiguration sent by the UE receiving the base station (such as the eNB of the LTE system) is obtained by acquiring the subframe configuration information, or by reading the SIB message of the interfering cell. (Connection Reconfiguration) message, the RRC connection configuration message carries the subframe configuration information, that is, the UE may obtain the subframe configuration information from the RRC connection reconfiguration message. When the UE is in the connected state, the UE may also read the foregoing subframe configuration information from the broadcast message sent by the base station, and it should be understood that the embodiment of the present invention is not limited thereto.

Optionally, as another embodiment, in step 102, when the subframe configuration of the second subframe of the interfering cell (also referred to as a “matching case”) satisfies one of the following time conditions, the UE is in the first The measurement of the cell to be measured in a subframe: the second subframe of the interfering cell is a non-flexible subframe; or the second subframe of the interfering cell is a flexible subframe, specifically, the first subframe and the second subframe are The subframe is configured for the downlink transmission, that is, the subframe of the second subframe of the interfering cell is configured as a DL subframe of the flexible subframe.

Optionally, when the second subframe of the interfering cell is determined to be a non-flexible subframe, that is, when the subframe configuration of the second subframe of the interfering cell is determined to meet the time condition, the UE performs measurement in the first subframe. Specifically, the time condition is applied to a scenario in which multiple interfering cells are configured as flexible subframes in the same subframe (for example, flexible subframe overlap of multiple cells), and the UE may be prevented from performing multiple cell flexible subframes. Find and compare. Or in a scenario where the interfering cell is configured with fewer flexible sub-frames, it can be avoided that the measurement is less accurate and the measurement is not accurate enough.

Optionally, when the second subframe of the interfering cell is determined to be a flexible subframe, that is, when the subframe configuration of the second subframe of the interfering cell is determined to meet the time condition, the UE performs measurement in the cell to be measured in the first subframe. Specifically, the time condition is that the flexible subframes of the multiple interfering cells are distributed in different subframe positions (for example, the flexible subframes of the multiple cells do not overlap), or the flexible subframes that are configured in the interfering cell are configured. Under the scene. In both scenarios, the range of measurement subframes of the UE is expanded, thereby increasing the accuracy of the measurement.

In particular, when there are many UL subframe configurations in the flexible subframe, the UE will measure in the UL subframe of the interfering cell flexible subframe; when the DL subframe configuration in the flexible subframe is configured, the UE will be flexible in the interfering cell. The DL subframe of the subframe is measured. The purpose is to expand the range of the number of subframes that the UE can measure, thereby increasing the accuracy of the measurement. When the UE does not satisfy the time condition, the UE does not perform the measurement operation of the cell to be measured.

Optionally, the UE may obtain the foregoing time condition from a network side device (such as a base station or a base station controller, etc.), that is, the UE receives the foregoing time condition sent by the network side device. Specifically, when the UE is in the connected state, the UE may receive the RRC connection configuration message sent by the base station, the RRC connection configuration message carries the time condition, or the UE receives the broadcast message sent by the base station, and the broadcast message carries the time condition. Or, when the UE is in an idle state, the UE receives a broadcast message sent by the base station, and the broadcast message carries a time condition, that is, a time condition is read from the broadcast message.

Certainly, the UE and the network side device (such as the eNB) may pre-agreed the foregoing time condition, and the embodiment of the present invention does not limit the manner in which the UE acquires the time condition.

Specifically, the subframe configuration of the interfering cell affects the measurement of the cell to be measured by the UE. For example, if the subframe configuration of the interfering cell is the measurement of the flexible subframe, the UE measures the RSRQ of the cell to be tested. When the subframe configuration of the cell (that is, the subframe configuration of the second subframe of the interfering cell) is the UL subframe of the flexible subframe, the UE measurement is performed because the RSSI (Received Signal Strength Indicator) value is low. RSRQ=RSRP (Reference Signal Received Power)/RSSI will be too high; if the subframe of the interfering cell is configured as the DL sub-frame of the flexible subframe at this time, the UE measurement is due to the high RSSI value. The RSRQ=RSRP/RSSI will be low. The embodiment of the present invention may limit the time for the UE to measure the cell to be tested by using the time condition. For example, in the foregoing case, the UE may treat the subframe in the second subframe of the interfering cell in the first subframe when the subframe is configured as a non-flexible subframe. The measured cell performs measurement. If the subframe of the second subframe of the interfering cell is configured as a non-flexible subframe, the UE does not perform measurement on the cell to be measured.

Similarly, when the subframe of the interfering cell is configured as a DL subframe of the flexible subframe, the UE may be configured as the DL subframe of the flexible subframe in the subframe of the second subframe of the interfering cell. The cell to be measured is measured in one subframe. It should be understood that embodiments of the invention are not limited to measurement benchmarks. The invention is not intended to limit the scope of the invention. For example, the measurement of the UE may be RSRQ.

In this way, the time condition related to the subframe configuration of the other cell (interfering cell) adjacent to the cell to be tested is used to limit the time for the UE to measure the cell to be tested, thereby avoiding the influence of the subframe configuration of the interfering cell.

The measurement of the UE, thereby improving the accuracy of the measurement.

In addition, after the step 102, when the UE is in the connected state, the UE performs measurement according to the measurement configuration sent by the base station, and after the measurement event is triggered, the UE reports the measurement result to the UE. The base station may perform cell handover or add a secondary cell or delete a secondary cell according to the measurement result reported by the UE. When the UE is in an idle state, the UE performs measurement according to the measurement acquired from the base station broadcast message, and the UE may perform cell selection or cell reselection according to the measurement result.

2 is a flow chart of a measurement method of one embodiment of the present invention. The method of Fig. 2 is performed by a network side device (e.g., a base station or a base station controller) and corresponds to the method of Fig. 1, and thus the description overlapping with the embodiment of Fig. 1 will be omitted as appropriate.

201. The network side device configures a time condition that the UE performs measurement in the first subframe of the cell to be tested.

202. The network side device sends a time condition to the UE, so that the UE performs a measurement operation on the cell to be tested in the first subframe when the subframe configuration of the second subframe of the interfering cell determines that the time condition is met.

The subframe configuration of the second subframe of the interfering cell corresponds to the first subframe of the cell to be tested, and the subframe configuration of the second subframe of the interfering cell is determined by the UE according to the obtained subframe configuration information of the interfering cell. The subframe configuration information is used to indicate a subframe configuration of each subframe included in a time period, and the subframe configuration includes an uplink subframe, a downlink subframe, and a flexible subframe.

In the embodiment of the present invention, the network side device configures a time condition for the UE to measure the cell to be measured in the first subframe of the cell to be tested, and sends the time condition to the UE, and the UE determines the cell to be tested by using the acquired subframe configuration information. The subframe configuration of the second subframe of the interfering cell corresponding to the first subframe, when the subframe configuration of the second subframe of the interfering cell determines that the time condition is met, performing a measurement operation on the cell to be measured in the first subframe, so that The UE selects a suitable measurement time to measure the cell to be tested, so as to avoid the subframe configuration with the interfering cell affecting the measurement of the UE, and improve the accuracy of the measurement.

It should be noted that a flexible subframe means that the subframe can be configured as a UL subframe or a DL subframe. That is to say, in a certain period of time, the flexible subframe can be configured as a DL subframe and configured as a UL subframe in another period of time.

It should also be noted that a time period may be one or more ΤΉ, one or more radio frames, or other time periods of other lengths. The embodiment of the invention does not limit this.

Optionally, as an embodiment, the time condition is: the second subframe of the interfering cell is a non-flexible subframe, and the first subframe and the second subframe are simultaneously configured for downlink transmission. That is, the second of the interference cell When the subframe is a DL subframe of the flexible subframe, the UE performs measurement in the cell to be measured in the first subframe. Or, the time condition is: the second subframe of the interfering cell is a non-flexible subframe, that is, when the second subframe of the interfering cell is a non-flexible subframe, the UE performs measurement in the first subframe.

Optionally, as another embodiment, the network side device takes the base station as an example. In step 202, when the UE is in the connected state, the base station may send an RRC connection configuration message to the UE, where the RRC connection configuration message carries a time condition, or The base station may also send a broadcast message to the UE, and the broadcast message carries a time condition; or when the UE is in an idle state, the base station sends a broadcast message to the UE, and the broadcast message carries a time condition.

Optionally, as another embodiment, the base station may further send subframe configuration information to the UE. Specifically, when the UE is in the connected state, the base station sends an RRC connection configuration message to the UE, the RRC connection configuration message carries the subframe configuration information, or the base station sends the subframe configuration information to the UE by using a broadcast message. Or, when the UE is in an idle state, the base station sends a broadcast message to the UE, and the broadcast message carries the subframe configuration information.

In addition, when the UE is in the connected state, the UE performs the measurement according to the measurement configuration sent by the base station, and after the measurement event is triggered, the UE reports the measurement result to the base station, and the base station can perform the cell handover according to the measurement result reported by the UE. Or add a secondary cell or delete a secondary cell.

In this way, the time condition of the UE to measure the to-be-measured area is limited by the time condition related to the subframe configuration of the interfering cell, and the subframe configuration of the interfering cell can be prevented from affecting the measurement of the UE, thereby improving the accuracy of the measurement.

The embodiments of the present invention are described in detail below with reference to specific examples.

For example, if the UE is in the connected state, the cell to be measured needs to be measured, and the interfering cell is the neighboring cell of the cell to be tested. The subframe configuration of the interfering cell affects the measurement of the cell to be measured by the UE.

Step 1: The base station sends an RRC connection configuration message to the UE.

The RRC connection configuration message carries a measurement configuration. Optionally, the RRC connection configuration message may also carry a time condition. It should be understood that the base station and the UE may pre-agreed the time condition.

Of course, the base station can send the time condition to the UE by using a broadcast message, and it should be understood that the embodiment of the present invention is not limited thereto.

Step 2: The UE determines, according to the time condition and the subframe configuration of the second subframe of the interfering cell, whether to perform measurement in the cell to be measured in the first subframe.

The UE determines whether the subframe configuration of the second subframe of the interfering cell satisfies the time condition. If the time condition is met, step 3 is performed. Optionally, the UE may read the SIB message of the cell to be tested to obtain Obtaining a subframe configuration of the second subframe of the interfering cell, or reading an SIB message of the interfering cell to obtain a subframe configuration of the second subframe of the interfering cell, or the UE may acquire the second subframe of the interfering cell from the RRC connection configuration message. The subframe configuration of the subframe, or the UE may acquire the subframe configuration of the second subframe of the interfering cell from the broadcast message.

For example, the time condition is: When the subframe of the interfering cell is configured as a UL subframe of the flexible subframe, the UE performs measurement on the cell to be measured. If the UE determines that the subframe configuration of the second subframe of the interfering cell satisfies the time condition, the UE performs measurement in the cell to be measured in the first subframe, otherwise the UE does not perform measurement. It should be understood that the example of the time condition is merely exemplary, and is not intended to limit the scope of the present invention. The time condition may be that the UE is in the first subframe when the second subframe of the interfering cell is a DL subframe of the flexible subframe. The measurement is performed on the cell to be measured, or the UE may measure the cell to be measured in the first subframe when the second subframe of the interfering cell is a non-flexible subframe.

Step 3: The UE performs measurements according to the measurement configuration.

Step 4: When the measurement result obtained by the UE meets the measurement time in the measurement configuration, the UE is triggered to report the measurement result to the base station.

If the UE determines that the subframe configuration of the second subframe of the interfering cell satisfies the time condition, the UE performs measurement in the cell to be measured in the first subframe. It should be understood that the examples of time conditions are merely exemplary and are not intended to limit the scope of the present invention. The time condition may be the first in the interfering cell. When the second subframe is a DL/UL subframe of the flexible subframe, the UE measures the cell to be measured in the first subframe, or the UE may treat the UE in the first subframe when the second subframe of the interfering cell is a flexible subframe. The measurement cell performs measurement and the like.

Step 4: The UE performs cell selection or cell reselection according to the measurement result.

In the embodiment of the present invention, the time condition related to the subframe configuration of the other cell (interfering cell) adjacent to the cell to be tested is used to limit the time for the UE to measure the cell to be tested, and the subframe configuration of the interfering cell can be prevented from affecting the measurement of the UE, thereby Improve the accuracy of the measurement.
