Title: METHODS AND APPARATUSES FOR CCI MITIGATION AND CHANNEL STATE CONDITION MEASURING AND REPORTING AND A NETWORK CENTRAL CONTROLLER
Abstract:
Embodiments of the present disclosure relate to a method and apparatus for cross-subframe co-channel interference (CCI) mitigation in a Time Division Duplex (TDD) system. The method may comprise: identifying a cluster-edge user equipment from user equipments in a cluster comprising at least one cell, based on information about large-scale fading for channels allocated to the user equipments; and allocating resource to the cluster-edge user equipment so that at least one of flexible subframes in uplink/downlink (UL/DL) configuration is disabled, so as to mitigate the CCI. Besides, in some embodiments of the present disclosure, it may further perform an adaptive cell clustering based on mutual coupling loss (MCL) with a dynamically adjusted MCL threshold, so as to improve the clustering and in turn further mitigate the CCI. With the embodiments of the present disclosure, the CCI may be mitigated substantially, and it may benefit from improved cell-average cell-edge performances and enhanced capability in adapting to the asymmetric traffic variations.
