    Abstract: A method and an apparatus for scheduling transmissions of a plurality of cells in a wireless communications system including one or more base stations is provided. The method comprises providing a set of virtual channels to enable an intra-cell transmission orthogonal to another transmission within each cell of the plurality of cells and inter-cell transmissions orthogonal to other transmissions across a cluster of cells associated with the one or more base stations. The method further comprises exchanging signaling messages between two or more base stations to coordinate- scheduling of the intra-cell transmission with the inter-cell transmissions for the cluster of cells. For optimizing a parameter associated with scheduling of a plurality of users from a cluster of cells in a wireless communication system, an optimal power level for the parameter of each active user may be searched to maximize an indication of system capacity of the wireless communication system. This enables a coordinated jointly scheduling of the users active in the cluster of cells based on the optimal power levels such that the total interference within the cluster may be minimized to maximize the system throughput/capacity.

    Abstract: An improved method is provided for reducing inter-carrier interference in the CDMA subchannels of hybrid OFDMA-CDMA systems. The results of decoding OFDMA tones are used to at least partially cancel interference from CDMA tones. Then, the CDMA tones are decoded. In specific embodiments, control information is obtained by an intial step of decoding the CDMA tones. The control information is used in decoding the OFDMA tones. Then, the decoding of the OFDMA tones and the decoding of the CDMA tones are performed iteratively, such that at least one instance of OFDMA decoding is used to cancel interference from the CDMA tones, and at least one instance of CDMA decoding is used to obtain improved control information for decoding the OFDMA tones.

    Abstract: A method is provided for controlling communications between a base station and a mobile device. The method comprises transmitting a pilot signal having at least one transmitted characteristic over a channel. A data rate control signal is received, indicating a variation between the transmitted characteristic and a corresponding actual characteristic of the pilot signal received at a remote location. The data rate control signal is modified based on a coefficient related to the bandwidth of the channel, and a transmission rate is determined based on the modified data rate control signal.
