Embodiment Construction

[0030] The radio communication system of the present invention has the following minimum configuration, which includes: during the occurrence of a downlink or uplink control channel that is not allocated to transmit control information, generating a pseudo signal to which an error correction code is added. format; a dummy format is sent from the base station to the mobile station instead of control information over a downlink or uplink control channel that is not assigned to send control information; decoding the control information transmitted by controlling the channel, checking whether the first value specified by the decoded control information is within an appropriate range, and performing error detection on the decoded control information; and once it is determined that the first value is not within an appropriate range Either upon detection of an error in the error detection of the decoded control information, in said any mobile station, stop decoding data sent over the ...

Abstract

The invention provides a radio communication system. A base station creates a dummy pattern added with an error correction code, during occurring of a control channel not allocated for transmission of control information, transmits the dummy pattern instead of control information at a power level lower than a normal power level. Amobile station decodes control information transmitted through the control channel, examines whether or not a value specified by the decoded control information is within a suitable range, and performs error detection of the decoded control information. The mobile station stops decoding of data transmitted through a data channel, upon judging that the value is not within the suitable range or detecting an error in the error detection.

Description

technical field [0001] The present invention relates to a radio communication system, and more particularly, to a radio communication system including a base station and a mobile station. The present invention also relates to a method of transmitting and receiving control information through a control channel, and a recording medium storing therein a computer program defining such a method. Background technique [0002] In a radio communication system comprising at least one base station and a plurality of mobile stations, for each radio frame, the base station typically transmits user data to the mobile station via a downlink data channel and transmits control information to the mobile station via a downlink control channel . The downlink control channel is used to notify the mobile station of control information such as decoding parameters of the downlink data channel. The radio frames transmitted from the base station to the mobile station may include radio frames witho...
