摘要： In the method, a source device places identifiers in data packets to be transmitted. The identifiers may include in-band flow control acknowledgment data in response to a flow control request transmitted from a destination device. When the destination device receives the transmitted data packets, the destination device will proceed based on the data contained in the data packets that are to be decoded at the destination device. If the decoded data packet contains in-band flow control acknowledgment data in response to a flow control request from the destination device, the destination device processes the data packets based on the received in-band flow control acknowledgment data.

摘要： A method for dynamically varying the allocation and distribution of a base station's resources in response to fluctuations in demand for services. The method includes transmitting a status signal from a base station to a base station controller over an Iub interface. The status signal may correspond to the demand of the base station's transmit power for a data transmission service, such as HSDPA, and for at least another service, such as a dedicated voice channel. In response to receiving the usage information signal, the base station controller may vary the transmit power of the base station allocated for HSDPA and/or for the dedicated voice, data and/or both integrated voice and data channel. In response to receiving users' status information for HSDPA services, the base station controller may vary its call admission status for HSDPA and/or dedicated voice, data and/or both integrated voice and data users.

摘要： 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.

摘要： In the method and apparatus for transmitting data packets, a source device places identifiers in data packets being transmitted. The identifiers identify data packets that the source device considers properly received by a destination device or identify data packets that have had their transmission aborted by the source device. When the destination device receives data packets including these identifiers and the identifiers identify data packets that the destination device has yet to receive, the destination device will proceed as if the identified data packets have been re-sequenced.

摘要： A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application. An admission control methodology is also provided which is implemented in a cooperative relationship with the further resource allocation process of the invention.

摘要： A rate feedback and adaptation scheme or system uses a rate of rate feedback asymmetrical with the rate of data rate adaptation. In particular, the rate adaptation system provides a rate of rate feedback slower than the rate of rate adaptation. Thus, by allowing the base station to change the data rate more frequently than the individual wireless units reports the rate information, the rate adaptation system can provide improved flexibility and more efficient use of wireless resources while reducing the processing and transmission overhead required to report the rate information. For example, every 3 slots, a wireless unit can calculate and report a rate for the wireless unit to use on a shared channel to send data. The base station receives the rates from the wireless units seeking to send data over the shared channel and selects a wireless unit to use the shared channel. If the base station can adapt the data rate every slot, the base station can adapt the data rate in accordance with a rate reported by another wireless unit, thereby improving system performance. Because of the small slot duration (for example, 0.67 microseconds), the relatively reduced rate of reporting should not adversely effect system performance since it is highly unlikely that the achievable data rate will change over a period of a slot under most operating conditions.
摘要翻译：速率反馈和适应方案或系统使用速率反馈速率与数据速率适配速率不对称。特别地，速率适配系统提供比速率适应速率慢的速率反馈速率。因此，通过允许基站比各个无线单元报告速率信息更频繁地改变数据速率，速率适配系统可以提供改进的灵活性和更有效地使用无线资源，同时减少报告所需的处理和传输开销费率信息。例如，每3个时隙，无线单元可以计算和报告无线单元在共享信道上使用的速率来发送数据。基站从寻求通过共享信道发送数据的无线单元接收速率，并选择无线单元以使用共享信道。如果基站能够适应每个时隙的数据速率，则基站可以根据另一无线单元报告的速率来调整数据速率，从而提高系统性能。由于小时隙持续时间（例如，0.67微秒），相对较低的报告速率不应对系统性能产生不利影响，因为在大多数操作条件下，可实现的数据速率在一段时间内将不可能改变。

摘要： 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.
