Embodiment Construction

[0017] In a multi-antenna system, each AP (similar to the base transceiver station (BTS) of the second generation mobile communication system and the node B (node ​​B) of the third generation mobile communication system) has one or more separate antennas inside , the typical antenna spacing is tens of meters to tens of kilometers. Antennas and APs are connected through optical fibers or coaxial cables.

[0018] According to the characteristics of the multi-antenna structure, the sliding handover method based on the multi-antenna structure of the present invention divides the handover into the handover initiated by the AP physical layer and the handover initiated by the network. According to different handover types, different handover methods are adopted. The sliding switching method of the present invention can be used for switching initiated by AP physical layer detection assistance, and the traditional switching method can be used for switching initiated by the network. S...

Abstract

A sliding switching method based on multi antennas structure is applied in access point (AP) of wireless system. The above AP includes multi antenna. The method includes following steps: the physical layer of the above AP monitors the upstream signal strength from mobile terminal received from all relevant antennas; selects an or multi antenna having strongest signal in all antennas to form enabled antenna cluster, and builds the connection between the mobile terminal and the enabled antenna cluster; when the physical layer of AP finds the signal strength received by some alternative antenna is exceeding the signal strength received by some antennas within the above enabled antenna cluster in preset period, AP raises the switching request to the physical layer, and directly replaces the enabled antenna by the alternative antenna, renews the enabled antenna cluster, and renews the connection between the mobile terminal and the enabled antenna cluster , the physical layer of AP reports the switching result to the wireless resources management layer of AP after completing the switching.

Description

technical field [0001] The present invention relates to a sliding switching method based on a multi-antenna structure, which is suitable for using Joint Transmission (JT for short), space-time code (STC), multiple-input and multiple-output antenna (MIMO), single-frequency orthogonal frequency Division multiple access (single frequency OFDMA), multi-antenna systems with technologies such as distributed antennas, such as the microcellular system disclosed in US patent application US 4932049, the system using the SSDT (Site Selection DiversityTransmission) mechanism, the bundled (bunched) system, and The system based on group cell architecture disclosed in Chinese patent application 01137188.9 and so on. Background technique [0002] The multi-antenna system has been widely concerned in the design of future mobile communication systems due to its great potential in increasing spectrum efficiency, improving communication quality, and its organizational structure flexibility, as ...
