摘要： A channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data.

摘要： To prevent consecutive transmission of a relative transmission rate control channel (RGCH) including a “Down” command and minimize deterioration in the service quality due to “Down” commands from non-serving cells, a transmission rate control method controls, at a mobile station, a transmission rate of uplink user data by using a first relative transmission rate control channel received from a serving cell and a second relative transmission rate control channel received from a non-serving cell. In the transmission rate control method, a maximum frequency of transmitting the second relative transmission rate control channel which includes a down command for instructing to decrease the transmission rate of the uplink user data is a value fixed in a mobile communication system or a value notified by a radio network controller.

摘要： A radio base station notifies a maximum allowable transmission rate of uplink user data to a mobile station by using a common transmission rate control channel. The mobile station increases the transmission rate of uplink user data up to the maximum allowable transmission rate by a predetermined step. When a predetermined condition is satisfied, the mobile station requests the radio base station to transmit a dedicated transmission rate control channel. The mobile station determines the transmission rate of uplink user data based on the dedicated transmission rate control channel transmitted from the radio base station.
