摘要： A communication system (100) transmits data packets from a sender (120A) to a receiver (130A) using hybrid automatic repeat request processes. The sender redundantly encodes each packet, divides the packet into subpackets, and sends the subpackets to the receiver in a time-interlaced manner. When the receiver returns a positive acknowledgement of a subpacket using an acknowledgement channel, the sender terminates transmission of the subpackets. The sender interprets the signals on the acknowledgement channel using a metric resulting from correlation of the signals with positive and negative acknowledgement symbols. The sender interprets low correlation of the acknowledgement channel signal with both positive and negative acknowledgement symbols as a preamble miss, and terminates transmission of the subpackets. After termination, the packet may be rescheduled for transmission. Early termination of packet transmission after a preamble miss improves bandwidth utilization and decreases latency of the packet with the missed preamble.
摘要翻译：通信系统（100）使用混合自动重复请求过程将数据分组从发送器（120A）发送到接收机（130A）。发送方对每个数据包进行冗余编码，将数据包划分为子数据包，并以时间间隔方式将子数据包发送给接收方。当接收方使用确认信道返回子包的肯定确认时，发送方终止子数据包的传输。发送者使用由信号与正和负确认符号的相关产生的度量来确认确认信道上的信号。发送方解释确认信道信号与正和负确认符号的低相关性作为前导码缺失，并终止子分组的传输。终止之后，可以重新安排分组以进行传输。前导码丢失后的数据包传输的提前终止提高了带宽利用率并降低了丢失前导码的数据包的等待时间。

摘要： In a wireless communication system, an apparatus and a method are provided for controlling reverse link interference among access terminals that are power controlled by a sector of a base station. In an embodiment, the maximum effective noise power spectral density is used as a parameter for controlling the level of reverse link loading, by setting a reverse activity bit (RAB) to signal the access terminals to reduce their data rates in order to minimize interference between the access terminals if the maximum effective noise power spectral density is above a predetermined threshold.

摘要： Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
