Abstract: PROBLEM TO BE SOLVED: To disclose a method that uses transmission power information so as to decide a data rate thereby integrating a voice service and a data service on a same frequency channel in which the available transmission power information indicates an amount of transmission power available for future data transmission on one data channel or more. SOLUTION: A transmitter or a base station transmits an available power message denoting a quantity of available transmission power to a mobile phone for a prescribed future time via a forward link. The mobile phone performs signal-to-interference measurement corresponding to the received forward link and the received interference and decides a data rate supported by the mobile phone by using the signal to interference wave and the available power message. The decided data rate corresponds to a maximum data rate at which a minimum level of quality of service can be achieved at the mobile phone.

Abstract: PROBLEM TO BE SOLVED: To provide a method for providing an efficient channel structure for a communication system to use a code for defining a communication channel. SOLUTION: A code space is formed for equally dividing an available code into M tiers on the basis of load conditions. Information is scheduled to be formed during a particular time slot and assigned to a particular tier. The information is transmitted by using all the codes of the tier assigned during the scheduled time slot.

Abstract: PROBLEM TO BE SOLVED: To provide a method for transmitting signaling information with high reliability. SOLUTION: First signaling information is transmitted via a main control channel. This first signaling information is defined as a pair of particular information; second signaling information is transmitted via, a second control channel; before transmission, the second signaling information is scrambled according to a scrambling procedure expressing the first signaling information; and the contents of the first signaling information are integrated in the second signaling information and encoded by this scrambling procedure to protect the integrity of the first and second signaling information.

Abstract: PROBLEM TO BE SOLVED: To identify a message group which can be used for transmitting by using previous messages. SOLUTION: As a message group contains the different number of messages, as a result, the messages from a smaller group can be expressed by using smaller bits than in the messages from a greater group. As the smallest group contains the messages accompanied by the highest possibility to be transmitted, the possibility of using the messages expressed by the smaller number of bits is maximized. The messages from the different groups are transmitted at different power level, and a receiver can determine the message group. As this result, the receiver identifies the messages by using previous messages, the power levels relating to the received messages, and the received message bits.

Abstract: A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.

Abstract: The capacity of a reverse link is improved by realizing a scheme to effect sharp changes in pilot channel transmit power (PCTP) and data channel to pilot power ratio (DCPR), coordinated with the start of the data channel transmission. The change in pilot power and data channel to pilot power ratio is also applicable to mobiles that use multiple pilots and/or multiple antennas at the transmitter and/or receiver.
