摘要： It is desired to suitably carry out transmission processing and reception processing carried out when transmitting a multicarrier signal where specific subcarriers are omitted. Therefore, the present invention carries out transmission avoidance processing operable when transmitting a multicarrier signal to replace signals corresponding to subcarriers, in a plurality of subcarriers, at frequency positions where transmission is avoided with a null signal. Subsequently, an inverse Fourier transform is carried out on the output of the transmission avoidance processing, the transmission power of the multicarrier signal that has been transformed is amplified in accordance with the number of subcarriers replaced with the null signal and the multicarrier signal is transmitted. When this multicarrier signal is received, subcarriers where transmission was avoided are estimated, and when it is estimated in the estimation that subcarriers where transmission was avoided are present, despreading and demodulation are carried out without using the subcarriers where transmission was avoided.

摘要： Systems and methods for operating in connection with mobile devices are described. The mobile devices may move between online and offline areas. In some instances, a prediction may be made as to when a mobile device will enter an offline area. The prediction may be based on sensor information. Data or a key may be transferred to the mobile device prior to entering the offline area.

摘要： To reduce power consumption for communication operation wherein a client terminal at the time of offline searches a base station or access point. A server uses a communication information predicting algorithm to predict a location or time whereby the server becomes an offline state over a movement route of a client terminal, and a location or time whereby the server returns to an online state, and informs to the client terminal. The client terminal suspends a communication function when reaching the informed offline predicted location or time. The client terminal at the time of offline determines that the current location or time has reached an online return predicted location or time using location recognition or point-in-time recognition, and restores the communication function.
