The present invention is designed to provide a user terminal, a radio base station and a radio communication method of novel structures that can achieve a good communication environment. A radio base station non-orthogonal-multiplexes downlink signals for a plurality of user terminals over a given radio resource, a user terminal having received the downlink signals for the plurality of user terminals decodes downlink signal for another user terminal, judges whether or not the downlink signal for the other user terminal has been successfully received, based on the decoding result of the downlink signal, reports a judgement result as to whether or not the downlink signal for the other user terminal has been successfully received and a judgement result as to whether or not a downlink signal for the user terminal has been successfully received, to the radio base station, and then the radio base station executes retransmission control of downlink signals based on reports from the user terminal.

Systems and methods for wireless power transfer

A wireless telecommunication system comprises base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system support the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

PURPOSE: A method for performing an uplink access in a broadband mobile communication system is provided to reduce a standby time taken for re-connection in case of channel congestion. CONSTITUTION: A terminal(400) transmits a bandwidth request message to a base station(450) through an access channel, namely, a contention-based connection channel in an uplink(411). The terminal(400) transmits the same bandwidth request message to the base station(450) after the lapse of a random backoff time(413). The terminal(400) re-attempts transmission of the same bandwidth request message after the lapse of the random backoff time(415). If there is no bandwidth as requested by the terminal(400)(417), the base station transmits a bandwidth request rejection message to the terminal(400)(419). Upon receiving a dedicated PN code, waiting time information, dedicated PN code lifetime information through the bandwidth request rejection message, the terminal(400) waits for the waiting time without attempting re-connection(423). When the waiting time elapses, the terminal(400) performs a contention-free connection to the base station by using the dedicated PN code as allocated within the dedicated PN code lifetime(427).
