摘要： A multiple mode data communication system and method provides the flexibility to schedule wireless unit transmissions and/or allow the wireless unit to transmit autonomously. In certain embodiments, the wireless units can transmit autonomously and/or use scheduling depending on the data rate, the length of the data packet or the type of data. For example, the wireless units can transmit autonomously at lower data rates and use scheduling at higher data rates. Thus, the multiple mode system enables wireless unit transmissions to be scheduled and/or be transmit autonomously, and wireless units can simultaneously operate in different scheduling and/or autonomous modes. Depending on the embodiment, the system can provide even greater flexibility in operation by permitting wireless units to be scheduled by a single base station, scheduled by a multiplicity of base stations simultaneously or otherwise, via coordination between base stations, scheduled by a multiplicity of base stations in an uncoordinated and asynchronous manner, allowed to transmit autonomously, and/or allowed to transmit autonomously under base station supervision (i.e. rate control/adjustment by the base station). Additionally, a forward and/or reverse link control channel structure is provided which can be used to implement the multiple mode data communication system and/or support various features enabling increased throughput over a shared data channel in a wireless communications system.

摘要翻译：多模式数据通信系统和方法提供了调度无线单元传输和/或允许无线单元自主传输的灵活性。在某些实施例中，无线单元可以根据数据速率，数据分组的长度或数据类型自主地传输和/或使用调度。例如，无线单元可以以较低的数据速率自主传输，并以更高的数据速率使用调度。因此，多模式系统使得能够自主地调度和/或发送无线单元传输，并且无线单元可以以不同的调度和/或自主模式同时操作。根据实施例，系统可以通过允许由多个基站同时或以其他方式调度的单个基站来调度无线单元，从而通过基站之间的协调，由多个基站调度来提供更大的灵活性站点以不协调和异步的方式允许自主传输和/或允许在基站监督下自主传输（即基站的速率控制/调整）。另外，提供了可以用于实现多模式数据通信系统和/或支持各种特征的前向和/或反向链路控制信道结构，从而能够在无线通信系统中的共享数据信道上实现增加的吞吐量。

摘要： A system and method for transmitting and receiving control information over a control channel of a wireless communication system where the conveyed information is coded and then transformed by a set of transform function selected from a plurality of sets of transform functions. The control information is transmitted as replicated sub-frames containing replicated code words and such a string of transformed replicated code words is referred to as a control message. At a receive end inverse transform functions from different sets of functions are applied to a sub-frame of a control message so that if the sub-frame is successfully decoded the inverse transform function applied to such frame allows the timing of the control message to be determined.

摘要： A method of identifying the available Walsh code space. The method includes at least one wireless unit receiving a Walsh code-based signal. The Walsh code-based signal may be transmitted by a base station, for example. The Walsh code-based signal may be realized by 13 bits, for example, corresponding to indices in a look-up table within the mobile unit that should not be employed. Thereafter, the wireless unit may determine the remaining Walsh code space. This determination step may include ascertaining which indices in the look-up table are relevant, and thusly, removing irrelevant indices. Subsequently, the step of determining the remaining Walsh code space may include examining the Walsh Table ID signal received from the base station to identify the remaining Walsh codes space.

摘要： A method for performing network control in wireless communication systems and a network entity for performing the same. The method and network entity pool at least one network parameter at the network entity, from at least two active set base transceiver stations and determine a current status of a mobile in the wireless communication system, using the pooled network parameters. The active set base transceiver stations may include a serving base transceiver station and a target base transceiver station. The network parameter may be a confidence metric and/or an error metric for each of a plurality of hypotheses, a power up/power down signal, and/or a measured signal-to-noise ratio and/or energy parameter of a pilot signal from the mobile. The current status of the mobile to be determined may be the mobile's decision to switch to the target base transceiver station transceiver or which base transceiver station transceiver the mobile is currently communication with. The network entity may be a base station controller or a base transceiver station in the active set of base transceiver station transceivers for the mobile in question.

The control preamble and encoded sub-frames may be decoded, and the decoded sub-frames may be used for removing interference caused by the known highest rate user transmission to all remaining transmissions of the group.
