Abstract

Embodiments of the present invention provide a resource allocation method and device in a wireless communication system. The method includes: obtaining information associated with a mobile terminal served by each base station from a plurality of base stations; analyzing the obtained information; allocating wireless resources to the base station based on the analysis; The radio resource allocation information sent to the corresponding base station. Distributed scheduling can be realized by adopting the technical solutions described in various embodiments of the present invention.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and more specifically relate to a resource allocation method and device in a wireless communication system, and a scheduling method and device in a wireless communication system. Background technique [0002] In order to achieve inter-cell interference coordination and avoidance, Coordinated multi-point operation (CoMP) operation under ideal backhaul has been introduced in LTE-A Release 11 (Rel-11), so that by allowing multiple transmission points Cooperate with each other to improve transmission performance. Currently, 3GPP is considering implementing further CoMP enhancement in small cell enhancement (small cell enhancement, SCE) Release 12 (Rel-12), especially in non-ideal backhaul situations. In the case of non-ideal backhaul, the non-ideal backhaul between a macro eNode B (eNB) and a small cell node (small cell node, SCN) or between two SCNs may be 5...
