Problems solved by technology

[0008] It can be seen that the above-mentioned solution is firstly based on the realization of MDC. This solution has the disadvantage of not being flexible enough: for example, if the operator hopes to exchange for a certain performance degradation (such as not using MDC) in exchange for saving transmission resources (no data forwarding), There is no way to meet this requirement on the basis of this scheme
Therefore, under the flat architecture, there is no overall solution for macro-diversity combining and interference control, which can comprehensively realize macro-diversity combining and interference control in a more flexible way, thereby improving system performance

Embodiment 1

[0045] Embodiment 1, taking the determination of the need to participate in MDC according to the channel quality of a non-serving cell, and taking Improved MDC and Improved IC as examples, the method for implementing macro-diversity combining and interference control integration provided by the embodiment example of the present invention is described with reference to the accompanying drawings. figure 1 It is a schematic diagram of a comprehensive implementation method of macro diversity combining and interference control in this embodiment.

[0046] Step 101: The base station of the serving cell receives the measurement report sent by the UE.

[0047] In this step, there are many possibilities for triggering the UE to report the measurement report. for example:

[0048] When adding or deleting or replacing an activated concentrated cell, the UE actively reports a measurement report to the base station of the serving cell, and the base station of the serving cell receives the...

Embodiment 2

[0064] In the second embodiment, the base station of a non-serving cell that needs to participate in the MDC is determined according to the transmission bandwidth resources, and the Improved MDC and the Improved IC are taken as examples, and the macro-diversity combination and interference control comprehensive implementation method provided by the embodiment of the present invention is described with reference to the accompanying drawings. figure 2 It is a schematic diagram of a comprehensive implementation method of macro-diversity combining and interference control.

[0065] Step 201: The base station of the serving cell determines the utilization of transmission bandwidth resources;

[0066] For the serving cell base station, the total bandwidth is a fixed value, and the serving cell base station can monitor its current remaining bandwidth in real time.

[0067] Step 202: The base station in the serving cell determines which base stations in the non-serving cell need to p...

Embodiment 3

[0071] Embodiment 3: In a scenario where enhanced interference control is performed, handover may be involved. The following describes this embodiment in detail with reference to the accompanying drawings.

[0072] If the user equipment UE is closer to non-serving cell base stations that perform enhanced interference control, that is, non-serving cell base stations that do not demodulate uplink data channels, the serving cell base station may perform handover operations according to the channel quality of these non-serving cell base stations.

[0073] The handover operation here may be an SRNS relocation process. For example, when the base station closer to the UE is a non-serving cell base station that implements the Improved IC function, the serving cell base station and the non-serving cell base station can perform soft handover and SRNS relocation procedures in a UE-independent manner. Therefore, the base station can provide uplink user data with a low bit error rate for t...

Abstract

The inventive embodiment provides a comprehensive implementation method of macro-diversity combining and interference control, a system and a base station. The method comprises the following steps: determining a non-serving cell base station needing to participate in macro-diversity combining MDC in a UE active set by a serving cell base station; transmitting an indication information to the non-serving cell base station needing to participate in MDC by the serving cell base station to indicate the non-serving cell base station to participate in MDC; and transmitting an indication information to other non-serving cell base stations in the active set by the serving cell base station to indicate the other non-serving cell base stations to carry out interference control operation. The system comprises the serving cell base station, the non-serving cell base stations, and a user terminal. The technical scheme can achieve macro-diversity combining and interference control in a more flexible manner, thereby optimizing the system performance.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, system and base station for realizing macro-diversity combination and interference control. Background technique [0002] UMTS is a third-generation mobile communication system using WCDMA air interface technology, and the UMTS system is usually called a WCDMA communication system. In the UMTS system, the coverage areas of adjacent cells overlap, and soft handover can be used to provide seamless handover, and the gain achieved by MDC (MacroDiversity Combining) can increase the anti-interference capability of the system. The following is a brief description of the implementation process of MDC: during the soft handover process, the mobile station communicates with two base stations through two different air interface channels at the same time. For the uplink, both base stations receive uplink user data. The uplink user data received by the two base statio...
