  • Patent number: 7483408
    Abstract: Soft-handoff methods involve receiving an uplink signal from a user equipment at more than one basestation. The uplink signals are processed at each basestation before being backhauled to a common point for use to derive a single signal from the user equipment. One problem with previous types of soft-handoff methods is that relatively complex processing is required at each basestation in order to demodulate and decode the signals. It is also desired to further increase uplink capacity as compared with known types of soft-handoff methods. This is achieved by backhauling signals without carrying out any decoding of the uplink signal at the basestation. The backhauled signals are combined at a common point using maximal ratio combining before being fully demodulated and decoded. As a result capacity is increased and required user equipment transmit power is reduced.

  • Publication number: 20040071115
    Abstract: A method for synchronous code division multiple access (SCDMA) scheduling including intelligent uplink SCDMA scheduling that incorporates polarization and/or spatial information to determine SCDMA code set assignment. The method includes scheduling algorithms to reduce observed interference and thus allow for a potentially significant increase in uplink capacity. This allows more terminals to be accommodated within a single site (i.e., higher sustainable user density) and/or a reduction in the number of base stations that must be deployed in order to cover a given area. This present invention is applicable to any high-speed wireless evolution SCDMA-based data system that would require highly efficient and optimized scheduling algorithms.
