    摘要： The present invention provides a method of coordinating the uplink transmissions from at least one mobile unit to a plurality of base stations. The method is implemented in a control and data plane entity and includes scheduling, at the control plane function, uplink signals for transmission from the mobile unit(s) to the plurality of base stations. The method also includes receiving, at the data plane function from the plurality of base stations, signals including scheduled uplink signals transmitted from the mobile unit(s) to the plurality of base stations. The method further includes estimating, at the data plane function, information bits transmitted in the scheduled uplink signals using the received signals and channel state information indicative of a plurality of wireless communication links between the mobile unit(s) and the plurality of base stations.

    摘要： A method of scheduling data communication over an uplink. The method enables two or more users seeking to transmit data over the uplink to be scheduled in response to their path loss. The user having the most attractive determined path loss among the two or more users seeking to transmit data over the uplink us scheduled first. Thereafter, the next user having the next most attractive path loss among the remaining users may be subsequently scheduled if the total noise rise leftover is greater than zero. This process repeats so long as or until the total noise rise leftover is about zero.

    摘要： Example embodiments are directed to methods of reducing inter-cell interference in wireless networks using successive interference cancellation (SIC). Example embodiments use inter-cell cooperation between cells and/or sectors to successfully decode their associated users' data signals and pass on the decoded data signals to other cells/sectors in order to reduce inter-cell interference and allow for improved decoding of users' data signals. Example embodiments include passing the decoded data signals via the backhaul. Example embodiments also include static and dynamic ordering of user data signals in conjunction with the application of SIC.
