Description

Method, device and system for suppressing adjacent zone interference

The present invention relates to the field of communications technologies, and relates to a method, device and system for suppressing adjacent zone interference. Background technique

With the development of communication technologies, more and more new technologies have emerged. In order to meet the needs of users and meet the challenges of other technologies, Wideband Code Division Multiple Access (WCDMA) systems adopt heterogeneous network termination. (Heterogeneous Network, Hetnet) networking. The heterogeneous network is networked by adding a small coverage base station (Pico base station) to the coverage of the macro base station. The benefit of Hetnet is that it increases cell throughput and its cost is lower than that of Homogeneous Network (Homonet).

In a heterogeneous network, the transmit power of the macro base station is larger than the transmit power of the micro base station. As a result, the uplink balance point and the downlink balance point of the user equipment (UE) in the heterogeneous network do not coincide. The uplink balance point is defined as: when the UE is in a certain position between the macro base station and the micro base station, the uplink power received by the macro base station and the micro base station from the UE is the same at this position. The downlink balance point is defined as: when the UE is in a certain position between the macro base station and the micro base station, the downlink power received by the UE from the macro base station and the second base station is the same at this position.

The inventors of the present invention have found that the downlink signaling of the micro base station cannot be correctly interpreted by the UE when the UE brings uplink interference to the micro base station, and the micro base station cannot control the transmission power of the UE. The micro base station cannot suppress the interference of the UE to it.

Referring to FIG. 1 , an embodiment of a method for suppressing neighbor interference provided by an embodiment of the present invention includes:

The network control device receives the interference signaling sent by any of the base stations, and obtains the information of the user equipment UE on the interference area of the any base station, where the interference area is any one of the UEs transmitting data in the area The base station causes interference, and any of the base stations cannot control the area of the UE on the area.

The interference area in the embodiment of the present invention means that the UE transmitting data on the area causes interference to any of the base stations, but the base station cannot control the UEs in the area.

Optionally, each UE sends a measured value to the network control device by using the base station that provides the service, and the network control device can determine, by using the measured value, whether the UE enters an interference region of the any base station.

Optionally, the measured value may be a path loss (or energy) of the UE and a base station serving the UE and a path loss (or energy) between the UE and the any of the base stations.

The interference signaling in the embodiment of the present invention is signaling capable of achieving the interference indication effect, and is not limited to the specific name of the signaling.

102. The network control device acquires information for controlling part or all of the base stations of the UE.

There may be multiple base stations controlling one UE, such as a base station in the UE activation set.

The UE may have multiple base station information in the active set. To reduce the transmit power of one UE, it may be performed by one or more base stations in the active set. Therefore, obtaining part or all of the base station information of the UE may be reduced. The purpose of the UE transmitting power.

103. The network control apparatus sends, to the part or all of the base stations, indication information of the first reduced transmit power, so that the part or all of the base stations reduce the transmit power of the UE.

The embodiment of the present invention uses the interference signaling sent by any base station to obtain the information of the user equipment UE on the interference area of the any base station, where the interference area is any one of the UEs in the area The base station causes interference, and the any base station is unable to control the area of the UE on the area; acquiring information for controlling some or all of the base stations of the UE; and transmitting to some or all of the base stations The first indication of reducing the transmit power, so that the part or all of the base stations reduce the transmit power of the UE. Compared with the prior art, when the uplink and downlink are unbalanced, the base station cannot reduce the transmit power of the UE, and the method for suppressing the neighbor interference provided by the embodiment of the present invention can reduce the UE that causes interference by the network control device and other base stations. The transmit power, thereby suppressing interference in the neighboring area.

Optionally, on the basis of the foregoing embodiment corresponding to FIG. 1, in another embodiment of the method for suppressing neighboring interference provided by the embodiment of the present invention, the interference signaling carries any one of the base stations for scheduling a user. The ratio of the total power to the total power received by the broadband;

Optionally, the interference signaling carries the ratio of the total power of the user to the total power of the broadband received (RSEPS, Received scheduled E-DCH power share), and the meaning of the ratio is in 3GPP 25.215. The provisions are: E-DCH Dedicated Physical Control Channel (E-DCHCH, E-DCH Dedicated Physical Control Channel) and dedicated physical data channel (E-DPDCH, E-) of all UEs scheduled by the base station within a certain period of time The sum of the power of the DCH Dedicated Physical Data Channel and the ratio of the total received power of the broadband (RTWP, Received Total Wideband Power).

The total power received by the broadband may be the total received power measured at the receiving end of the base station over a period of time, including thermal noise, the sum of all channels of the UE scheduled by the base station, and the power of the neighboring zone interference. Thermal noise N0 power does not change much, it can be considered that N0 is a constant.

When the second threshold is smaller, information for controlling part or all of the base stations of the UE is acquired.

In the above optional embodiment, the interference ratio is calculated. It can be seen from the calculation formula of the interference ratio that the RSEPS is large and the interference ratio is small, so the interference ratio can be calculated without counting the RSEPS. When the RSEPS is less than the second threshold, the interference ratio may be considered to be higher than the first preset threshold.

For the base station that is providing services for the UE, the UE's transmit power can be reduced to a suitable time. The scope.

If the indication of the first reduced transmit power does not carry the indicated number of times, then the non-serving base station needs to be dropped once.

For a base station that is providing services for a UE, the UE's transmit power can be reduced by a number of times each time.

For a non-serving base station, only one UE's transmit power can be reduced at a time, such as ldB, so the non-serving base station has to be lowered multiple times to fall to the appropriate range.

After the step of transmitting the indication information of the first reduced transmit power to the part or all of the base stations, the method further includes:
