摘要： The invention discloses a timing synchronization method in a User Equipment (UE) which is served in a first cell of a first synchronous communication network and also located in a second cell of a second synchronous communication network. The method comprises receiving a message from a communication node of the first network, the message including clock offsets of the first cell and the second cell or timing difference there between, and calculating downlink synchronization of the second cell from downlink synchronization of the first cell and the clock offsets/timing difference.

摘要： A method of and a network controller (304) for recognizing an out-of-sync BS in a TDD based cellular communication network is provided. The method comprises the steps of receiving information reported by one or more BSs having uplink interference from the out-of-sync BS (414), and locating the out-of-sync BS based on the information (416). A BS and an NMS for use with the above network controller (304) and a TDD based cellular communication network comprising at least the above network controller (304) and the above BS (306-1, 306-2,..., 306-n) are also provided.
