BASE STATION DEVICE, UPSTREAM SINR MEASURING METHOD, UPSTREAM SCHEDULING METHOD AND RECEIVIG QUALITY MEASURING METHOD

摘要

A mobile station sends a base station a control signal (an ACK signal/a NACK signal, etc.) with a plurality of specific patterns limited to communication control processing at the base station, and the base station uses this control signal to carry out an upstream SINR measurement. The base station switches in response to the existence or non-existence of the control signal between one method of the SINR measurement using the control signal of this kind and the other of the SINR measurement using the same exclusive signal for the SINR measurement as a conventional one. Further, the base station carries out an up-link scheduling based on an upstream SINR measuring result. In this scheduling, the base station may use a control arranged with sub-carrier dispersion to measure an SINR for every frequency block and carry out a frequency scheduling.
