Abstract: In one aspect, a method may include grouping a plurality of wireless communication devices on a moving platform into two or more non-overlapping groups of the wireless communication devices, distributing a first list of tracking areas to the groups of the wireless communication devices, changing the first list of tracking areas to a second list of tracking areas for a first group of the wireless communication devices in response to the moving platform entering into an overlapping region between a first tracking area and a second tracking area of the first list of tracking areas, and changing the first list of tracking areas to the second list of tracking areas for a second group of the wireless communication devices in response to the moving platform entering into an overlapping region between the second tracking area and a third tracking area of the first list of tracking areas.

Abstract: Various embodiments of a self-adapted multi-antenna selection technique based on broadband wireless access network for high-speed railway are provided. Compared with conventional techniques, the proposed strategy adaptively pairs antennas of an antenna array associated with a base station in response to the fast-changing distance between the base station and the antenna array on a high-speed train. The proposed technique achieves a channel matrix with full rank and thereby improves the channel capacity. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
