Abstract: An EnodeB or a transmitting device intermittently generates synchronization signals, and then performs perfect omnidirectional pre-coding processing on the synchronization signals; the synchronization signals after perfect omnidirectional pre-coding processing pass through a transmission channel and are then received by a mobile terminal or a receiving device, and the mobile terminal or the receiving device uses the received synchronization signals and local replicas of the synchronization signals for receiving and synchronization processing. An EnodeB or a transmitting device generates vector signals via low-dimensional space-time coding, and then performs perfect omnidirectional pre-coding processing on the vector signals; the transmitted signals after perfect omnidirectional pre-coding processing pass through a transmission channel and are then received by a mobile terminal or a receiving device, and the mobile terminal or the receiving device uses the received signals for signal receiving processing.

Abstract: In a wireless communication terminal in a wireless communication system for performing a control not to transmit signals, or to transmit signals with a reduction in a transmission power by a part of radio resources for a downlink signal in a cell provided by a base station, the terminal receives control information in generating a report related to a measurement result of the cell provided by the base station, monitors a state of a radio link with an own cell, and performs measurement on reception of the downlink signal. If an instruction for restricting the measurement to a part of the radio resources is included in the control information from the base station after the radio link failure occurs, the terminal generates and transmits a radio link failure report including the measurement result in the radio resources as instructed when the radio link failure occurs.
