摘要： A method and apparatus for controlling a Network Load Balancing (NLB) algorithm that balances a traffic load between multiple downlink (DL) sectors in a cellular telecommunication network. A Connection Integrity Preservation (CIP) algorithm, which runs on top of the NLB algorithm in the Radio Network Controller/Base Station Controller (RNC/BSC), minimizes the risk of degrading network performance due to NLB offload decisions. The CIP algorithm may override an NLB offload decision, for example, if there have been too many offload failures, there are no target DL sectors available to acquire an offloaded Access Terminal (AT), or the offloaded AT is not acquired within a threshold time period. The CIP algorithm ensures required metrics are collected, and minimizes the impact on RNC/BSC processing due to Routing Update messages needed to make offload decisions. The invention enables the NLB algorithm to realize its potential without negative side-effects.
摘要翻译：一种用于控制在蜂窝电信网络中平衡多个下行链路（DL）扇区之间的业务负载的网络负载平衡（NLB）算法的方法和装置。在无线电网络控制器/基站控制器（RNC / BSC）中运行的NLB算法之上运行的连接完整性保护（CIP）算法最大限度地降低了由于NLB卸载决定而导致网络性能下降的风险。 CIP算法可以覆盖NLB卸载决定，例如，如果发生了太多卸载故障，则没有可用于获取卸载的接入终端（AT）的目标DL扇区，或者在阈值时间内未获取卸载的AT 期。 CIP算法确保收集所需的度量标准，并最大限度地减少由于进行卸载决定所需的路由更新消息对RNC / BSC处理的影响。本发明使得NLB算法能够实现其潜在性而没有负面的副作用。

摘要： A method, apparatus, and radio receiver system for canceling multi-user interference in a single-carrier radio communication system. A front-end receiver such as a RAKE receiver receives a radio signal formatted in a sequence of frames, and outputs a plurality of user signals. An ordering unit determines for a current frame, an order in which to decode and remove the interference contributions of the plurality of user signals. The order may be based on a list of user signals sorted in the order of descending signal-to-interference-plus-noise ratio (SINR), modified by the success or failure of attempts to decode each user signal. A frame calculator determines a coherence time, which is used to calculate the number of subsequent frames in which the user signals are decoded in the determined order.

摘要： Multiple antennas at the transmitter and receiver increase the capacity in a wireless communication system. Received signal quality can be enhanced through diversity by transmitting the same symbol on multiple antennas. Data rate can be increased through multiplexing by transmitting different symbols on the transmitting antennas. Operating in one particular mode only is generally not suitable. Choosing diversity or multiplexing by taking into account the location of a user can enhance both throughput and reliability.

摘要： A communication device includes a decoder that sequentially decodes sub-packets of a first packet that contain redundant traffic information. The decoder identifies a first sequence location where it successfully decoded one of the sub-packets of the first packet to output the traffic information. The decoder then sequentially decodes sub-packets of a second packet starting at a second sequence location that is determined in response to the first sequence location. Related methods, user equipment node, and radio access network nodes are also disclosed.

摘要： Upon receiving a particular data unit by a receiving layer of a wireless device, it is detected that a previous data unit earlier in sequence to the particular data unit has not yet been received by the receiving layer. A timer is started in response to the detecting, where the timer has a time-out period that is variable dependent upon a parameter associated with receipt of the particular data unit. Upon expiration of the timer based on the timeout period, the receiving layer generates an error indication.
