Carrier resource allocation method and device of heterogeneous network

Abstract

The invention discloses a carrier resource allocation method and a carrier resource allocation device of a heterogeneous network. The method comprises the step that: a base station determines carrier resource allocation information according to user information and a user carrier resource condition. The carrier resource allocation information comprises one or a combination of the following information: using condition of a different carrier frequency / operator carrier resource, a symmetrical selection way for uplink and downlink carriers, a carrier dispatching type, and a pairing way and a link relationship of uplink and downlink carrier resources. The device comprises a carrier resource allocation module, a link carrier selecting module, a carrier dispatching module and a carrier resource pairing and link indicating module. By the method, the setting of the carrier dispatching type, the carrier-dispatching way, the carrier resource allocating way, and pairing and linking of the uplink and downlink carrier resource is realized. The carrier resource allocating and dispatching way can be flexibly configured. A better compromise is performed between improvement on the user and system performance and improvement on carrier resource utilization rate.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a carrier resource configuration method and device in a heterogeneous network. Background technique [0002] In the next-generation broadband wireless communication network, how to support a larger bandwidth under the bandwidth of the current wireless communication system becomes a key factor in improving the throughput of user terminals (UT) between cells and the average throughput of user terminals and face severe challenges. [0003] In a heterogeneous network, since there are great differences in performance and service requirements between different types of base stations (Base Station, BS) and different modules of home information machines, can resource allocation and mapping be more flexible and efficient? Using and supporting the interoperability of different networks in heterogeneous networks has become an urgent issue to be solved. [0004] At present, in the lon...

Problems solved by technology

However, the current carrier aggregation discussed in LTE-Advanced does not take into account the impact of inter-cell interference that plays an important role in the throughput of user terminals between cells and the average throughput of user terminals. If the aggregated carrier part suffers from severe inter-cell interference, then , even if a larger bandwidth is obtained, the throughput and rate performance of the user terminal using this part of the aggregated carrier will be severely degraded due to severe inter-cell interference, thereby offsetting the benefits of carrier aggregation
