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.

Method for forming and communication of heterogeneous neighbor base station information in a broadband wireless access communication system

PROBLEM TO BE SOLVED: To provide a method of requesting and allocating an upstream bandwidth in a broadband wireless access communication system using a multi-hop relay system. SOLUTION: The method includes: a step of receiving a bandwidth allocation request message including request bandwidth information from one or more terminals; a step of detecting the requested bandwidth from the terminals through the message when receiving the bandwidth allocation request message; a step of calculating a total requested bandwidth by summing the requested bandwidth from the terminal, generating a new bandwidth allocation request message including the calculated total request bandwidth information and sending the new message to a base station. Thus, it is advantageous that radio resources between a relay station and a base station can be reduced and efficiently managed. COPYRIGHT: (C)2007,JPO&INPIT
