摘要： A mobile station is provided which does not cause a reduction in the speech transmission capacity. Branches receive radio signals from base stations and operate independently of one another. A branch operation control section controls the operation of the individual branches to detect a destination-side base station based on the reception levels of signals from surrounding base stations, to cause part of the branches to establish synchronization of spreading code and carrier frequency with respect to the destination-side base station while causing the other part of the branches to maintain communication with a departure-side base station after the destination-side base station is detected, and to cut off the communication with the departure-side base station after the synchronization is established.

摘要： A plurality of chips generated by spectrum spreading from each of the bits constituting transmission information are distributed along the time axis, and transmitted. At the receiving end, the transmission information is recovered while integrating information of the chips distributed along the time axis. In a first aspect of the present invention, the transmission information is repeated multiple times, and then the resulting information is spread by a spreading code to generate the transmission data. In a second aspect of the present invention, the transmission information is first spread by a spreading code and then interleaved to generate the transmission data.

摘要： In transmission in which MIMO is applied, there have been problems that the number of variable parameters increases and the number of information bits necessary for control channel increases. When the number of simultaneous multiplex users in one frame increases, there is also a problem of increased control channel information in proportion to the number of users. Error correction coding is performed for the control channel information based on the Adaptive Modulation and Coding scheme, and the above error correction coded control channel information is transmitted after being modulated with a predetermined modulation scheme, and further, according to propagation condition, the coding rate in the above error correction coding is made variable.

摘要： A radio channel control method for controlling, in a radio communication system having a transmitter and a receiver, a radio channel from the transmitter toward the receiver. The method includes receiving a signal transmitted from the transmitter by the receiver, measuring reception quality of the signal, generating information which indicates increment or decrement of the reception quality, and controlling a modulation or coding for the radio channel based on the information.

摘要： The present method adds uplink data to a transmission request sent to the base station from the mobile station for obtaining permission for data transmission, or to a channel establishment request sent from the mobile station to the base station for establishing a channel in order to send the transmission request therethrough. This makes it possible to suppress delay caused by negotiation prior to actual uplink data transmission as much as possible, thereby realizing efficient uplink data transmission, that is, improved throughput of uplink communication.
