CDMA COMMUNICATION METHOD

摘要

Mobile station radio communication equipment MS is provided with a transmission-reception amplifying section AMP, a radio communication section TRX, a base-band signal processing section BB, a mobile station control section MS-CNT, and a terminal interface section TERM-INT. In multi-code transmission, the availability of a frequency resource and communication quality are improved by transmitting control information (pilot symbol and TPC symbol) only with one designated individual physical channel boosted in electric power. In addition, the availability of the frequency resource and communication quality are improved and, at the same time, the power consumption is reduced by deciding the transmission/cancellation of transmission information in accordance with the communication quality and communication state. Moreover, the availability of the frequency resource is improved and the power consumption is reduced by avoiding the occurrence of frequent calls.
