摘要： Error flags are generated for use in source decoding of a source-coded bit stream transmitted through a channel of a communication system. The source-coded bit stream is channel coded using at least one channel code, and the channel code is decoded in a soft-decision channel decoder to generate a received version of the source-coded bit stream and one or more reliability measures associated with a designated portion of the received version of the source-coded bit stream. The reliability measures are processed to generate one or more error flags indicative of the presence of an error in the corresponding portion of the received version of the source-coded bit stream. The invention allows different detection capabilities to be used for different portions of the received version of the source-coded bit stream, and further allows these detection capabilities to be changed dynamically at the receiver. The error flags may be used to trigger an error mitigation/concealment algorithm in the source decoder. Advantageously, the error flags can be matched to frames or subframes of the source-coded bit stream, such that the performance of the error mitigation/concealment algorithm is substantially improved relative to its performance when using error flags generated from a conventional outer block code.

摘要： In a cellular network, randomness is introduced into a transmitted signal at each transmitter, and the resulting received signal, which is the sum of all received signals, fluctuates more in time than a signal transmitted without the introduced randomness. While the introduction of randomness can diminish reception of some parts of the signal at the receiver, the transmitted signal can be encoded using forward error correction coding techniques, which allows the receiver to recover all of the signal information despite some diminished reception. Such randomization provides time diversity so that receivers can have more consistent performance. For broadcasted data, where users with the worst channel condition dictates the overall performance, having consistent performance across users can improve the overall network performance.
摘要翻译：在蜂窝网络中，在每个发射机处将随机性引入到发射信号中，并且作为所有接收信号之和的结果接收信号在时间上比在没有引入随机性的情况下传输的信号波动更大。尽管随机性的引入可以减少在接收机处的信号的一些部分的接收，但是可以使用前向纠错编码技术来编码所发送的信号，这允许接收机尽可能地减少接收而恢复所有的信号信息。这种随机化提供时间分集，使得接收机可以具有更一致的性能。对于广播数据，具有最差信道条件的用户决定整体性能的用户，具有一致的用户性能可以提高整体网络性能。

摘要： An apparatus and method for determining a beamforming vector in a codebook-based transmission beamforming system are provided. In a feedback method for a receiver in a codebook-based transmission beamforming system, forthcoming channel values for a forthcoming period are generated using M present and previous channel estimates. Effective channel gains for all transmission beamforming vectors included in a codebook are calculated using the forthcoming channel values. A codebook index corresponding to the maximum effective channel gains is fed back to a transmitter.

摘要： In a radio access network (e.g., a cellular network), a radio node is configured to monitor one or more characteristics of a stream of data packets destined for an access terminal (e.g., a cellular telephone, laptop computer, etc.) to determine whether there is congestion in a network supplying the stream of data packets. If the radio node detects congestion, the radio node transmits a congestion alert to another device to cause the rate at which data enters the network to be slowed. The rate may be slowed either directly (e.g., by an upstream device which slows the rate at which the upstream device supplies the data to the network) or indirectly (e.g., by a downstream device which requests a slower delivery of data from the radio node).
摘要翻译：在无线电接入网络（例如，蜂窝网络）中，无线电节点被配置为监视去往接入终端（例如，蜂窝电话，膝上型计算机等）的数据分组流的一个或多个特性，以确定在提供数据包流的网络中是否存在拥塞。如果无线电节点检测到拥塞，则无线电节点向另一个设备发送拥塞警报，导致数据进入网络的速率变慢。速率可以直接减慢（例如，由上游设备降低上游设备向网络提供数据的速率）或间接地（例如，由请求从无线电节点传送较慢数据的下游设备））。
