Abstract: A method of data packet communication. The method includes the step of transmitting CQI in response to an inactive state. The step of transmitting CQI may include receiving an incoming signal associated with one or more real time duplex services, such as voice over IP ("VoIP"), gaming and/or two-way video applications, for example. Thereafter, the method includes the step of pausing the transmission of CQI in response to a break period in the inactive state. The break period may be initiated by transmitting an outgoing signal associated with at least one real time duplex service, such as voice over IP ("VoIP"), gaming and/or two-way video applications, for example. Moreover, the step of pausing may include receiving a do-not-transmit signal to initiate the break period.

Abstract: A method is provided for controlling transmissions between a base station and a plurality of mobile station over a plurality of subcarriers. Each mobile station is free to transmit over its own unique set of subcarriers, depending upon the quality of the various subcarriers. That is, the quality of at least a portion of the subcarriers is determined with respect to each mobile station. Thereafter at least a portion of the subcarriers are selected based upon the determined quality, and then information is transmitted to each mobile station using its own unique set of subcarriers.

Abstract: A method of wireless communication. The method includes the step of transmitting at least a first sub-frame from a first voice frame. If the first sub-frame is received by the wireless unit, an acknowledgement message is transmitted, and the remaining sub-frames from that voice frame are not transmitted. If the first sub-frame is not received by the wireless unit, however, a non-acknowledgement message is transmitted. Here, the base station retransmits at least another sub-frame from the first voice frame.

Abstract: A base station switching system includes a wireless unit that waits before switching from a previous base station to a new base station after the wireless unit has indicated to the wireless communications system the identity of the new base station. Thus, the wireless unit continues to receive data from the previous base station, and the data forwarded to the previous base station will not be lost. For example, whenever a wireless unit decides to switch to a new base station, the wireless unit sends an indication to the wireless communications system of the identity of the selected base station. Before the wireless communications system can forward the data to the new base station, the wireless communications system continues to forward data to the previous base station. To avoid losing such data, the wireless unit continues receiving data from the previous base station. Once the previous data forwarded to the previous base station is sent to the wireless unit and/or the new data has been forwarded to the new base station, the wireless communications system can signal the wireless unit, and in response, the wireless unit can begin receiving data from the new base station.

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: An uplink and downlink channel structure supports a shared downlink data channel. The new structure accommodates advanced physical and Medium Access Control (MAC) layer techniques, such as incremental redundancy (IR), fast adaptation to channel conditions, and multiple input multiple output (MIMO) antenna configuration. The proposed changes are intended to lead to a downlink structure that achieves higher spectral efficiency for the packet oriented services over then shared downlink channel. Additionally, the new structure uses the base station transmit power information and of the channelization (OVSF) code space more efficiently.
