Description

Method, device and user equipment for measuring scalable bandwidth cell

The present invention relates to the field of communications, and in particular, to a measurement method, apparatus, and user equipment for a scalable bandwidth cell.

Background technique

At present, the bandwidth of the Universal Mobile Telecommunications System (UMTS) is fixed. In order to make UMTS applicable to different frequency bandwidths, a scalable universal mobile communication system S-UMTS (Scalable Universal Mobile Telecommunications System) cell technology is introduced. The S-UMTS may also be referred to as a Fractional-Universal Mobile Telecommunications System (F-UMTS).

The S-UMTS cell technology is still considered to be a UMTS cell technology, except that its bandwidth is lower or higher than the UMTS cell bandwidth (5 MHz or 4.2 MHz). In the prior art, the bandwidth of the S-UMTS cell is usually set to UMTS. One-ninth of the bandwidth of the cell, and the power of the S-UMTS cell is one-N of the UMTS cell, and N is a scaling factor. For example, the value of N may be 2, 4, 0.5, 0.25, and the like.

In the UMTS cell, the neighboring cell information is sent by the network side when the UE needs to measure the same-frequency cell and the inter-frequency cell, whether the user equipment (User Equipment) is in the idle state or the connected state. The neighbor cell information includes the same-frequency cell information and the different-frequency cell information. However, the neighboring cell information sent by the network side also uses the technical solution of sending the neighbor cell information by the UMTS cell. Generally, the same frequency cell information does not include the center frequency and bandwidth information of the same frequency cell, and the different frequency cell information only includes different The center frequency of the frequency cell, but does not include the bandwidth information of the inter-frequency cell.

Therefore, when the S-UMTS cell is included in the neighbor cell information, when the S-UMTS cell is measured, whether the S-UMTS cell is sent in the same-frequency cell information or the inter-frequency cell information, the UE cannot obtain the neighbor cell. The frequency range of the S-UMTS cell is known in the information, so that the UE can only measure the neighbor cell information according to the frequency range of the currently camped cell.

The technology in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. The present invention is described in a clear and complete manner, and it is obvious that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. Embodiment 1 The embodiment of the present invention provides a measurement method of a scalable bandwidth cell. As shown in FIG. 1 , an execution body of the method is a user equipment UE.

101. The user equipment UE receives the neighbor cell information that is sent by the network side, where the neighbor cell information includes the frequency range information of the scalable bandwidth S-UMTS cell.

After the UE camps on a cell, the UE obtains neighbor cell information of the currently camped cell of the UE.

When the UE is in the idle state, the network side sends neighbor cell information to the UE through the measurement control system information in the System Information Block (SIB). When the UE is in the connected state, the network side sends the neighbor cell information to the UE by using the measurement control information MCI (Measurement Control Information). Both the measurement control system information and the neighbor cell information in the measurement control information include co-frequency cell information and inter-frequency cell information.

When the UE is in the idle state, the same-frequency cell information is sent through the same-frequency cell information list in the measurement control system information, and the inter-frequency cell information passes the inter-frequency cell information list in the measurement control system information. Issued. When the UE is in the connected state, the same-frequency cell information is sent by using the same-frequency measurement system message in the measurement control information, and the inter-frequency cell information is sent by using the inter-frequency measurement system message in the measurement control information. .

The neighbor cell information may include UMTS cell information and/or S-UMTS cell information. The UMTS cell information and/or the S-UMTS cell information may be sent by using the same-frequency cell information or the inter-frequency cell information.

The network side may add information that can obtain the frequency range of the S-UMTS cell in the same-frequency cell information, where the frequency range information of the S-UMTS cell may include at least two of the following information: , ending frequency point, center frequency point, Scale factor N. Alternatively, the frequency range information of the scalable bandwidth S-UMTS cell may also include a scaling factor N and a partition to which the frequency range of the S-UMTS cell belongs.

The network side may add frequency range information of the S-UMTS cell to the delivered inter-frequency cell information, where the frequency range information includes at least two of the following information: a starting frequency point, an ending frequency point, and a center frequency Point, scale factor N. The scaling factor N indicates that the bandwidth of the S-UMTS cell is one-Nth of the UMTS cell bandwidth, and N is any real number greater than 0. For example, the bandwidth of a UMTS cell is 5 MHz or 4.2 MHz. For example, when the N value in the S-UMTS cell information in the neighbor cell information is 2, if the bandwidth of the UMTS cell is 5 MHz, the bandwidth of the S-UMTS cell is 2.5 MHz. The partition information to which the frequency range of the S-UMTS cell belongs indicates the partition number of the frequency range of the S-UMTS cell. For example, if the scaling factor N is 2, the frequency range of the UMTS cell is 2000 MHz to 2005 MHz, and the frequency range of the S-UMTS cell belongs to 2, the frequency range of the S-UMTS cell is 2002.5 MHz. ~2005MHz. It should be noted that, for the case where the frequency range of the S-UMTS cell includes the partition information, the N value is a natural number greater than or equal to 1.

The starting frequency point refers to frequency point information capable of obtaining a starting frequency value of a frequency range of the S-UMTS cell. For example, the initial frequency value of the S-UMT S cell; or when the end frequency value or the center frequency value of the S-UMTS cell has been obtained, the starting frequency point may also be relative to the ending frequency value or center The offset value of the frequency value. Of course, the starting frequency point may also be other information that can obtain the starting frequency value of the frequency range of the S-UMTS cell, which is not specifically limited in this embodiment of the present invention. The end frequency point refers to frequency point information capable of obtaining an end frequency value of a frequency range of the S-UMTS cell. For example, the ending frequency value of the S-UMTS cell; or when the starting frequency value or the center frequency value of the S-UMTS cell has been obtained, the ending frequency point may also be relative to the starting frequency value or the center frequency The offset value of the value. Of course, the end frequency point may be other information that can obtain the end frequency value of the frequency range of the S-UMTS cell, which is not specifically limited in this embodiment of the present invention. The center frequency point refers to frequency point information capable of obtaining a center frequency value of a frequency range of the S-UMTS cell. For example, the center frequency value of the S-UMT S cell. Of course, the frequency information of the center frequency value of the frequency range of the S-UMTS cell can be obtained, and the implementation of the present invention is not described herein again.

102. The UE performs measurement on the S-UMTS cell in the neighbor cell information according to the frequency range information of the S-UMTS cell included in the neighbor cell information, and obtains a measurement result.

The UE performs measurement on all cells in the neighbor cell information delivered by the current camping cell and the network side. For the S-UMTS cell, the UE may obtain the frequency range of the S-UMTS cell according to the frequency range information of the S-UMTS cell delivered by the network side. The UE performs measurement on all cells in the current camped cell and the neighboring cell of the UE according to the frequency range of the UMTS cell and the obtained frequency range of the S-UMTS cell, and obtains a measurement result. Specifically, the UE measures, according to the frequency range of the UMTS cell and the acquired frequency range of the S-UMTS cell, the signal quality of all cells in the current camped cell and the neighboring cell of the UE, and obtains the The signal quality value of all cells in the cell and neighboring cells currently camped by the UE.

The signal quality value may specifically be: a pilot reference signal received power RSRP (Reference Signal Receiving Power), a path loss value, a pilot signal to noise ratio Ec/N0, and the like.

The UE determines whether to perform cell reselection or report the measurement result to the network side according to the measurement result and the preset measurement threshold. When the UE is in an idle state, the UE determines whether to perform cell reselection according to the measurement result and a preset measurement threshold, and further determines a serving cell of the UE. If the measurement result of the S-UMTS cell in the neighbor cell information is greater than the preset measurement threshold, the UE selects the S-UMTS cell as the serving cell of the UE.

When the UE is in the connected state, the UE determines whether to report the measurement result to the network side according to the measurement result and the preset measurement threshold, so that the The network side determines whether to perform cell handover according to the measurement result. The embodiment of the present invention provides a method for measuring a scalable bandwidth cell. As shown in FIG. 2, the execution body of the method is a network side, for example, a Radio Network Controller (RNC).

The network side sends the neighbor cell information to the UE, where the neighbor cell information includes frequency range information of the scalable bandwidth S-UMTS cell, so that the UE is configured according to the S-UMTS cell included in the neighbor cell information. The frequency range information is used to measure the S-UMTS cell in the neighbor cell information.

After the UE camps on a cell, the network side sends neighbor cell information to the UE. When the UE is in the idle state, the network side sends the neighbor cell information to the UE by using the measurement control system information in the system information block. When the UE is in the connected state, the network side sends the neighbor cell information to the UE by using the measurement control information. Both the measurement control system information and the neighbor cell information in the measurement control information include co-frequency cell information and inter-frequency cell information. In the prior art, the same-frequency cell information in the neighbor cell information does not directly include the bandwidth information and the center frequency, and the UE cannot obtain the frequency range of the S-UMTS cell. The network side may add a parameter that can calculate a cell frequency range by adding the same-frequency cell information. Specifically, if the network side sends the frequency range information of the S-UMTS cell by using the same-frequency cell information, the frequency range information of the scalable bandwidth S-UMTS cell may include at least two of the following information: Point, end frequency point, center frequency point, scaling factor N; or, the frequency range information of the scalable bandwidth S-UMTS cell may also include a scaling factor N and a partition to which the frequency range of the S-UMTS cell belongs.

In the prior art, the inter-frequency cell information in the neighbor cell information includes only the center frequency point, and the bandwidth information is not included, and the UE cannot obtain the frequency range of the S-UMTS cell. Therefore, the network side may send information of a frequency range of the scalable bandwidth S-UMTS cell in the delivered inter-frequency cell information. Specifically, if the network side sends the frequency range information of the S-UMTS cell by using the inter-frequency cell information, the frequency range information of the scalable bandwidth S-UMTS cell includes at least two of the following information: , end frequency point, center frequency point, scaling factor Sub N. The scaling factor N indicates that the bandwidth of the S-UMTS cell is one-Nth of the UMTS cell bandwidth, and N is any real number greater than zero. For example, the bandwidth of a UMTS cell is 5 MHz or 4.2 MHz. For example, when the value of N in the S-UMTS cell information in the neighbor cell information is 2, if the bandwidth of the UMTS cell is 5 MHz, the bandwidth of the S-UMTS cell is 2.5 MHz. The partition information to which the frequency range of the S-UMTS cell belongs indicates the partition number of the frequency range of the S-UMTS cell. For example, if the scaling factor N is 2, the frequency range of the UMTS cell is 2000 MHz to 2005 MHz, and the frequency range of the S-UMTS cell belongs to 2, the frequency range of the S-UMTS cell is 2002.5 MHz. ~2005MHz. It should be noted that, for the case where the frequency range of the S-UMTS cell includes the partition information, the N value is a natural number greater than or equal to 1.

The starting frequency point refers to frequency point information capable of obtaining a starting frequency value of a frequency range of the S-UMTS cell. For example, the initial frequency value of the S-UMT S cell; or when the end frequency value or the center frequency value of the S-UMTS cell has been obtained, the starting frequency point may also be relative to the ending frequency value or center The offset value of the frequency value. Of course, the starting frequency point may also be other information that can obtain the starting frequency value of the frequency range of the S-UMTS cell, which is not specifically limited in this embodiment of the present invention.

The end frequency point refers to frequency point information capable of obtaining a ending frequency value of a frequency range of the S-UMTS cell. For example, the ending frequency value of the S-UMTS cell; or when the starting frequency value or the center frequency value of the S-UMTS cell has been obtained, the ending frequency point may also be relative to the starting frequency value or the center frequency The offset value of the value. Of course, the end frequency point may be other information that can obtain the end frequency value of the frequency range of the S-UMTS cell, which is not specifically limited in this embodiment of the present invention.

The center frequency point refers to frequency point information capable of obtaining a center frequency value of a frequency range of the S-UMTS cell. For example, the center frequency value of the S-UMT S cell. Of course, the frequency information of the center frequency value of the frequency range of the S-UMTS cell can be obtained, and the implementation of the present invention is not described herein again. Embodiments of the present invention provide a method for measuring a scalable bandwidth cell, where the network The network side sends the S-UMTS cell frequency range information to the UE by sending the neighbor cell information, so that the UE can measure the S-UMTS cell according to the received frequency range information of the S-UMTS cell, and obtain Measurement results. In this way, the UE can obtain the frequency range of the S-UMTS cell, so that the measurement of the S-UMTS cell by the UE is more accurate.

Embodiment 2 The embodiment of the present invention provides a method for measuring a scalable bandwidth cell. Taking the UMTS as an example, the network side is specifically a radio network controller RNC, as shown in FIG. 3 .

301. The RNC sends the neighbor cell information to the UE, where the neighbor cell information includes frequency range information of the S-UMTS cell.

After the UE camps on a cell, the UE obtains neighbor cell information of the currently camped cell of the UE. When the UE is in the idle state, the RNC sends the neighbor cell information to the UE through the measurement control system information in the system information block SIB. When the UE is in the connected state, the RNC sends the neighbor cell information to the UE by using the measurement control information MCI.

The neighbor cell information may include UMTS cell information and S-UMTS cell information.

When the UMTS cell and the S-UMTS cell included in the neighbor cell information are the same-frequency cell of the current camping cell of the UE, the UMTS cell and the S-UMTS cell information are sent by the same-frequency cell information; When the UMTS cell and the S-UMTS cell included in the neighboring cell information are the inter-frequency cells of the current camping cell of the UE, the UMTS cell and the S-UMTS cell information are sent by using the inter-frequency cell information.

In the existing UMTS cell technology, the same-frequency cell information in the neighbor cell information does not directly include the bandwidth information and the center frequency point. For a UMTS cell, the bandwidth is fixed. When the UMTS cell is the same-frequency cell of the current camping cell, the frequency range of the UMTS cell is the same as the frequency range of the current camping cell, so the RNC There is no need to send relevant parameters to the UE that can obtain the frequency range of the UMTS cell. However, for an S-UMTS cell, the UE cannot obtain the frequency range of the S-UMTS cell. Therefore, in the embodiment of the present invention, the RNC may add information that can obtain the frequency range of the S-UMT S cell in the same-frequency cell information, where the frequency range information of the S-UMTS cell may include the following information. At least two: starting frequency, ending frequency, center frequency, scaling factor N. Alternatively, the frequency range information of the scalable bandwidth S-UMT S cell may also include a scaling factor N and a partition to which the frequency range of the S-UMT S cell belongs.

Specifically, the RNC may add a frequency range information item of the S-UMT S cell by using an intra-frequency cell information list or an intra-frequency measurement system message that sends the same-frequency cell information. Specifically, as shown in Table 1, the frequency range information item of the S-UMT S cell may be added after the same-frequency cell identification item in the intra-frequency cell information list. Of course, the RNC may also add the frequency range information item of the S-UMTS cell after the other items in the list, when the same-frequency cell information list is sent, which is not specifically limited in this embodiment of the present invention.

The frequency range information item of the S-UMT S cell includes frequency range information of the scalable bandwidth S-UMT S cell.

In the table 1, the "OP" entry in the frequency range information item of the S-UMT S cell is optional, that is, when there is an S-UMT S cell in the neighboring cell of the currently camped cell of the UE, Adding a frequency range information item of the S-UMTS cell after the same-frequency cell identification item in the same-frequency cell information list; when there is no S-UMT S cell in the neighboring cell of the current camping cell of the UE, the same-frequency cell information There is no frequency range information item of the S-UMTS cell after the co-frequency cell identification item in the list. The entry corresponding to the "quantity" indicates the number of S-UMT S cells in the neighboring cell of the currently camped cell of the UE determined by the RNC. The entry corresponding to "type and reference" indicates the name of the list of the S-UMTS cell frequency information or the name of the reference list of the frequency information. Specifically, Table 2 provides a list of frequency range information of the S-UMT S cell. If the frequency range information of the S-UMTS cell includes the scaling factor N and the partition information of the frequency range of the S-UMT S cell, the foregoing two information may be added in Table 2, as shown in Table 2. . Of course, if the frequency range information of the S-UMT S cell includes at least two of the following information: a starting frequency point, a ending frequency point, a center frequency point, and a scaling factor N, The information of the start frequency point, the end frequency point, the center frequency point, and the scaling factor N is directly added to the frequency range information list of the S-UMTS cell.

Table 1 List of co-frequency cell information

Table 2 List of frequency range information of the S-UMTS cell

Specifically, when the frequency range information of the S-UMTS cell is sent by the intra-frequency measurement system message, the frequency range information item of the S-UMTS cell may be added to the intra-frequency measurement system message, where the S-UMTS cell The frequency range information item includes frequency range information of the S-UMTS cell.

Further, in the existing UMTS cell technology, the inter-frequency cell information in the neighbor cell information includes only the center frequency point, and does not include the bandwidth information. For a UMTS cell, the bandwidth is fixed when the UMTS cell is the user equipment When the inter-frequency cell of the pre-resident cell is used, the UMTS cell frequency range can be obtained by combining the center frequency point delivered by the RNC. However, for the S-UMTS cell, the bandwidth is uncertain, only the center frequency point, and the frequency range of the S-UMTS cell cannot be obtained.

Therefore, in the embodiment of the present invention, the RNC may add frequency range information of the S-UMT S cell to the delivered inter-frequency cell information, where the frequency range information includes at least two of the following information: Point, end frequency point, center frequency point, scaling factor N. Specifically, the RNC may join the frequency range information of the S-UMTS cell in the inter-frequency cell information list or the inter-frequency measurement system message of the delivered inter-frequency cell information. Specifically, a corresponding start may be added to the frequency point information list of each S-UMTS cell included in the “type and reference” entry of the frequency information information item of the inter-frequency cell information list or the inter-frequency measurement system message. At least one of the frequency point, the end frequency point, and the scaling factor N. As shown in Table 3, the scaling factor N is added after the UARFCN (UTRA absolute radio frequency channel number) downlink entry in the cell frequency information list, where UARFCN downlink is used.

302. The UE receives neighbor cell information delivered by the RNC.

The UE receives the neighbor cell information that is sent by the RNC, and the neighbor cell information includes the frequency range information of the S-UMTS cell. 303. The UE performs measurement on the S-UMTS cell in the neighbor cell information according to the S-UMTS cell frequency range information included in the neighbor cell information, and obtains a measurement result.

The UE performs measurement on all cells in the neighbor cell information delivered by the current camping cell and the RNC. For the S-UMTS cell, the UE may obtain the frequency range of the S-UMTS cell according to the frequency range information of the S-UMTS cell delivered by the RNC. Specifically, if the frequency range information is the partitioning factor N and the partition information to which the S-UMTS cell frequency range belongs, the bandwidth of the S-UMTS cell may be first determined according to the scaling factor N, and further The frequency range of the S-UMTS cell may be determined according to the partition information to which the frequency range of the S-UMTS cell belongs.

For example, when the N value in the S-UMTS cell information in the neighbor cell information is 2, the bandwidth of the S-UMTS cell is 2.5 MHz; the center of the S-UMTS cell delivered by the RNC. When the frequency is 2000 MHz, the frequency range of the S-UMTS cell can be determined to be 1998.75 MHz to 2001.25 MHz. It should be noted that the UE obtains the frequency range of the S-UMTS cell according to any two of the scaling factor N, the starting frequency point, the ending frequency point, and the center frequency point.
