Uplink and downlink diversity for fast cell site selection

摘要

The present invention is directed to forward link and reverse link diversity in a wireless telecommunications network. The present invention solves the reverse link/forward link dependence between a mobile station and a base station of a network by purposely selecting different base stations or sectors of a base station for reverse-link and forward-link transmissions. In one embodiment, reverse link traffic channel transmissions are targeted to a different base station than the base station from which the forward link traffic channel transmissions originate and respective control information of these channels are embedded or transmitted with the opposite link. Such diversity may be activated only in signal conditions that have a certain predefined value or mobile station locations that exhibit a sufficient chance of experiencing a forward or reverse link failure. Activation of the diversity scheme may also depend on whether more than one base station or sector has link-quality within an appropriate range or the degrading effect of the increased power on capacity is acceptable.
