Methods and apparatus of enhancing performance in wireless communication systems

摘要

Methods and apparatus for supporting and using multiple communications channels corresponding to different transmit technologies and/or access technologies in parallel within a cell of a wireless communications system are described. Mobile nodes support multiple technologies and can switch between the technology being used at a particular point in time, e.g., from a first channel corresponding to a first technology to a second channel corresponding to a different technology which provides better transmission characteristics, e.g., a better perceived channel quality. Mobiles maintain at least two sets of channel quality information at any one point in time. Mobiles select the better channel and communicate the channel selection to the base station or communicate channel quality information for multiple channels to the base station and allow the base station to select the channel corresponding to the technology providing the better conditions for the mobile. Different mobiles in the same cell may support different technologies.

主权项

1. A method of operating a base station comprising the steps of:
transmitting signals corresponding to a plurality of different communications channels in parallel, at least two of said communications channels corresponding to different communications technologies; receiving information, from a wireless terminal which supports said plurality of different communications channels; and
selecting between said communications channels corresponding to different communications technologies for use in communicating with said wireless terminal as a function of a rate of motion of said wireless terminal.
