摘要： The present invention provides a diversity transmission system. The diversity transmission system includes a diversity transmitter receiving incoming symbols. The diversity transmitter includes at least one transmitter antenna transmitting a plurality of multi-carrier modulated signals. Each multi-carrier-modulated signal includes a corresponding processed symbol sub-block stream. Each symbol of the processed symbol sub-block stream is based on a linear transform of a plurality of incoming symbols. The diversity transmission system further includes a diversity receiver. The diversity receiver includes at least one receiver antenna receiving the plurality of multi-carrier modulated signals after the multi-carrier modulated signals having been modified by transmission channels between the transmitter antennas and the receiver antenna. The diversity receiver further includes at least one multi-carrier demodulator for demodulating the received multi-carrier modulated signals and generating a demodulated symbol stream. A symbol-processing unit receives the demodulated symbol stream and generates a stream of outgoing symbols. The invention also includes a diversity transmitter. The diversity transmitter includes a symbol-processing unit for receiving a stream of incoming symbols and generating a plurality of processed symbol streams. The processed symbol streams are based on linear transforms of the incoming symbols. A plurality of multi-carrier modulators generate a plurality of multiple-carrier modulated signals. Each multi-carrier modulator receives a corresponding processed symbol stream and generates a multiple-carrier-modulated signal based on the corresponding processed symbol stream.

摘要： A technique for setting the transmission powers of individual D2D (device-to-device) transmitters using a distributed power control technique is described. Each individual D2D transmitter learns the interference levels that it imposes on an eNB (evolved Node B) and on D2D receivers other than its partner D2D receiver. The D2D transmitter is then able to adjust its transmission power accordingly. Such managing of interference temperature via distributed power control enables the network to maximize its reuse of time-frequency resources.

摘要： An interference mitigation system randomizes transmissions to cell-edge users by carefully controlling the probability of transmission to these users, thereby creating a virtual fractional frequency system that does not require extensive frequency management and coordination across the network. In some embodiments, the interference mitigation system identifies severely interfered links and reduces the probability of transmission on these links, with the result being a reduced probability of interference.

摘要： Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference.
