    摘要： A dirty paper precoding (“DPC”) method for broadcasting a signal is disclosed that takes advantage of knowledge of the structure of interference in order to avoid the quantization noise that results in the conventional DPC method. The proposed method modifies the Tomlinson-Harishima precoding (“THP”) scheme by selecting a constellation and mapping scheme that is designed based on the known interference modulation structure of the interference signal, which is typically directed to a second receiver. In a particular embodiment, a source signal and an interference signal are QAM modulated. The modulation structure information of the interference signal is known to the receiver. At the transmitter the source signal is precoded based on the known interference structure, and a common mapping rule is implemented, such that the received signal can be decoded at the receiver without requiring a modulo operation at either the transmitter or receiver.

    摘要： Systems and methods which provide data communication content delivery through a hybrid network implementation are disclosed. A hybrid network configuration may utilize a broadcast communication technique to deliver large amounts of data communication content to one or more mobile communication device via uni-directional network links and a uni-cast communication technique via bi-directional network links with the one or more mobile communication device to facilitate delivery and utilization of the data communication content. Data content delivery loss recovery techniques implemented according to embodiments of the invention utilize network links of the hybrid network other than or in addition to the uni-directional network links to implement loss recovery techniques such as a hybrid repeat technique, a hybrid retransmission technique, hybrid statistical feedback technique, and/or combinations thereof.

    摘要： A method and apparatus for antenna switching, grouping, and channel assignments in wireless communication systems. The invention allows multiuser diversity to be exploited with simple antenna operations, therefore increasing the capacity and performance of wireless communications systems. Channel characteristics indicative of signal reception quality for downlink or bi-directional traffic for each channel/antenna resource combination are measured or estimated at a subscriber. Corresponding channel characteristic information is returned to the base station. Channel characteristics information may also be measured or estimated for uplink or bi-directional signals received at each of multiple receive antenna resources. The base station employs channel allocation logic to assign uplink, downlink and/or bi-directional channels for multiple subscribers based on channel characteristics measured and/or estimated for the uplink, downlink and/or bi-directional channels.
