Description

Method for evaluating coexistence interference, user equipment and base station

The present invention relates to the field of communications, and in particular, to a method for evaluating coexistence interference, a user equipment, and a base station. Background technique

In order to achieve ubiquitous network access for users, terminal devices need to install multiple sets of transceivers to access different networks. For example, the terminal device can be installed with a transceiver of a Long Term Evolution (LTE) system, an Industrial Scientific Medical (ISM) system (eg, WiFi, Bluetooth BlueTooth, etc.). Since multiple transceivers in the same terminal are very close together, the power of one system transmitter may be much higher than the power of another system receiver.

FIG. 1 is a schematic diagram of a current interference coexistence. As shown in FIG. 1, the terminal device may include an LTE system, a GPS system, and a Bluetooth/WiFi system. The LTE system may interfere with the Bluetooth/WiFi system, and the Bluetooth/WiFi system may also The LTE system generates interference.

Currently, in the LTE-A coexistence interference avoidance mechanism, the base station can configure a coexistence interference frequency set for the user equipment, so that the user equipment only needs to evaluate whether there is coexistence interference on the frequency of the coexistence interference frequency concentration. The user equipment can then transmit the evaluation results of these frequencies to the base station, thereby reducing the number of times the user equipment evaluates the frequency to a certain extent and improving the performance of the system.

However, in the process of implementing the present invention, the inventors have found that the disadvantages of the prior art are: the coexistence interference frequency set adopted by the user equipment is configured by the base station to the user equipment after being generated by the base station side; the user equipment needs to be evaluated by the serving base station or Coexistence interference on the frequencies supported by its neighbor base stations.

In some scenarios, such as when the user equipment is in the central location of the serving cell, the frequencies that may be used are those that can be supported by the serving base station and can be allocated to the user equipment, that is, the user equipment only needs to evaluate these Coexistence interference on frequency. For the frequency of the neighbor base station, the serving base station obviously does not allocate these frequencies to the user equipment, so there is no need to evaluate. However, according to the existing scheme, as long as the frequency of the neighbor base station is configured, the user equipment Coexistence interference on these frequencies will still be evaluated; this increases the unnecessary overhead of the user equipment.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of the present invention.

Example 1

The embodiment of the invention provides a method for evaluating coexistence interference, which is applied to the user equipment side. 2 is a flowchart of an evaluation method according to an embodiment of the present invention. As shown in FIG. 2, the evaluation method includes:

Step 201: The user equipment generates, according to the coexistence interference frequency information sent by the base station, a coexistence interference frequency set according to the location;

Step 202: Perform coexistence interference assessment on the frequency of the coexistence interference frequency concentration.

In this embodiment, the base station may be a serving base station serving the user equipment, and the service The base station may send the coexistence interference frequency information through a system message or a dedicated signaling (for example, RRC reconfiguration signaling) to perform coexistence interference configuration on the user equipment.

In one embodiment, the coexistence interference frequency information may include one or more coexistence interference frequency subsets, and a region identification corresponding to each coexistence interference frequency subset. And, the user equipment selects one or more coexistence interference frequency subsets according to the location to generate a coexistence interference frequency set.

The area identifier may be a base station identifier, or may be a service area identifier. Each coexistence interference frequency subset contains frequencies in a region that support coexistence interference indications, ie, in this region, the user equipment can evaluate coexistence interference at each frequency in this subset.

In a specific implementation, the coexistence interference frequency information may include: a) a frequency in each subset; and b) an area identifier corresponding to each subset. Table 1 schematically shows the coexistence interference frequency 4 I from , .

Table 1

In addition, any two different subsets may contain the same frequency.

3 is a diagram showing an example of a coexistence interference frequency configuration. As shown in FIG. 3, a serving base station (base station 1) can support {!, , / ₃ }, a neighbor base station (base station 2) can support, / ₅ }, a neighbor base station ( Base station 3) can support, / ₄ , / ₆ }.

As shown in FIG. 3, the serving base station can configure the information shown in Table 2 according to the frequencies that the neighboring cell and the neighboring cell can support. Table 2 shows an example of a coexisting interference frequency information corresponding to FIG.

Table 2

In this embodiment, the selecting, by the user equipment, the one or more coexistence interference frequency subsets to generate the coexistence interference frequency set may include: if the user equipment is in the central location of the service area, selecting the service area corresponding to the service area The coexistence interference frequency subset is used as a coexistence interference frequency set; if the user equipment is in a non-central location of the service area and is close to other areas, Then, the coexistence interference frequency subset corresponding to the service area is combined with the coexistence interference frequency subset corresponding to the other area as a coexistence interference frequency set.

For example, in the scenario shown in FIG. 3, if the user equipment is in the central location of the service area of the base station 1, the user equipment may use the coexistence interference frequency subset {, / ₂ , / ₃ } corresponding to the base station 1 as Coexistence interference frequency set, only coexistence interference on / ₂ and / ₃ can be evaluated;

If the user equipment is in the service area of the base station 1 and is close to the service area of the base station 2, the user equipment may coexist the coexistence interference frequency subset {_/!, , / ₃ } corresponding to the base station 1 and the base station 2 The interference frequency subset {/ ₃ , , / ₅ } is merged, and the combined / ₂ , / ₃ , / ₅ } is used as the coexistence interference frequency set, and the user equipment can evaluate the frequency of the coexistence interference frequency concentration, fi, / ₃ , coexistence interference on / ₄ and / ₅ .

In another embodiment, the coexistence interference frequency information may include a cell list for performing coexistence interference estimation, where the cell list includes one or more cell information, and each cell information corresponds to one coexistence interference frequency; and, the user equipment is located according to Location, select one or more coexistence interference frequencies to generate a coexistence interference frequency set.

The cell information may include a cell identifier, such as a physical cell identifier (PCI), or may include an index information corresponding to the cell. However, the present invention is not limited thereto, and other cell identifiers may be used according to actual conditions, for example, It may be E-UTRAN cell global identifier (ECGI, E-UTRAN cell global identifier) 0 wherein the specific content or index PCI information may refer to the prior art, is not repeated here.

In this embodiment, the cell information in the cell list may include the cell information of the serving base station, and may also include the cell information of the neighboring base station, and may also include the cell information of the serving base station and the cell information of the neighboring base station. For example, taking PCI as an example, Table 3 shows an example of another coexisting interference frequency information corresponding to FIG.

As shown in Table 3, multiple PCIs may be included in the cell list, and each PCI may correspond to a base station and a frequency. As long as the PCI is obtained, it can be determined at which frequency of which base station, and the specific content of the PCI can refer to the prior art. It should be noted that the correspondence shown in Table 3 is only for convenience of description. The entry of the cell list may only include the cell identifier, and does not include the information of the frequency and the base station.

In this embodiment, the user equipment selecting one or more coexistence interference frequencies to generate the coexistence interference frequency set according to the location may specifically include: if the user equipment is in the central location of the serving cell, selecting one corresponding to the serving cell or The plurality of coexisting interference frequencies generate a coexistence interference frequency set; if the user equipment is in a non-central location of the serving cell and close to other cells, the one or more coexistence interference frequencies corresponding to the serving cell and one or more coexistence interferences corresponding to other cells After the frequencies are combined, a coexistence interference frequency set is generated.

For example, in the scenario shown in FIG. 3, if the user equipment is located at the center of the service area of the base station 1, the user equipment may select the coexistence interference frequency corresponding to the cell of the base station 1, fi, and generate a coexistence interference frequency set. /!, , / ₃ }, can only evaluate / / ₂ and coexistence interference;

If the user equipment is in the service area of a base station and is approaching the service area of the base station 2, the user equipment may coexistence interference frequency cell corresponding to the base station 1,, / 2, ₃ and the base station corresponding to the cell frequency coexistence interference, / ₄ , / ₅ to merge, the combined { , , / ₃ , / ₅ } as the coexistence interference frequency set, the user equipment can evaluate the frequency of the coexistence interference frequency set /i, , , / ₄ and / ₅ Coexistence interference.

Alternatively, the selecting, by the user equipment, the one or more coexistence interference frequencies to generate the coexistence interference frequency set may include: the user equipment selects a frequency of the cell that can be detected and is in the cell list, and generates coexistence interference. Frequency set. The cell that can be detected may be a cell whose signal quality is greater than a certain threshold. However, the specific detection mode may be determined according to actual needs.

For example, in the scenario shown in FIG. 3, if the user equipment detects the cells whose cell identifiers are PCI2, PCI3, and PCI6, and the three cells are in the list shown in Table 3, the user equipment may select the corresponding / ₂ , , , Generate a shared interference frequency set {/ ₂ , , / ₅ }.

Different from the prior art, the coexistence interference frequency set is generated on the base station side, and the coexistence of the present invention is The set of scrambling frequencies is dynamically generated by the user equipment according to the location, thereby reducing unnecessary terminal overhead. It is to be noted that the foregoing describes only how the user equipment generates the coexistence interference frequency set by using the coexistence interference frequency subset or the cell list. However, the present invention is not limited thereto, and a specific implementation manner may also be determined according to actual conditions.

In this embodiment, the location at which the user equipment is located can be determined by the signal strength measured by the user equipment. In a specific implementation, if the user equipment measures that the signal strength of the cell is greater than a preset threshold, it is determined that the user equipment is at or near the cell.

For example, when the user equipment finds that a certain cell belonging to a certain base station (where the cell does not necessarily work on a certain frequency in the configured frequency subset) has a signal strength greater than a certain threshold, it may be determined that the cell is approaching the The cell, from which it can begin to evaluate the coexistence interference on the frequency in the subset of frequencies configured for this base station.

In addition, the location where the user equipment is located can also be determined by the obtained location information. For example, specific location information can be obtained through a Global Positioning System (GPS), thereby determining the location of the user equipment. However, the present invention is not limited thereto, and a specific position determining manner may be selected according to actual conditions.

Step 403: The user equipment evaluates the coexistence interference of the frequency of the coexistence interference frequency concentration;

Step 404: The user equipment sends the evaluation result to the base station.

It can be seen from the above embodiment that the user equipment generates a coexistence interference frequency set according to the location, and performs coexistence interference evaluation on the frequency of the coexistence interference frequency concentration. It is possible to make the user equipment not evaluate the frequencies that are impossible to allocate, thereby reducing unnecessary terminal overhead. Example 2
