摘要： According to certain embodiments, methods and systems for toggling transmission parameters in a heterogeneous network to achieve a target block error rate by a network node may include obtaining a signal-to-noise ratio (SINR) estimate from channel quality information for a downlink between a network node and a wireless device. For each of a first code word and a second code word to be transmitted on the downlink, a block error rate estimate may be obtained based on the SINR estimate. The network node may then determine at least one expected SINR for the first code word and the second code word. The at least one expected SINR may be determined as a function of the SINR estimate and the block error rate estimate. Based on the at least one expected SINR for the first code word and the second code word, a modulation and coding scheme (MCS) for obtaining a target block error rate may be selected. The network node may then transmit the first code word on a first transmission layer and the second code word on a second transmission layer during a first transmission time interval. In a second transmission time interval, the network node may transmit the first code word on the second transmission layer and the second code word on the first transmission layer.

摘要： A wireless network and serviced mobile station manages VOIP telephony calls by incorporating control information into VOIP datagrams. The control information includes an indication of the data rate of the VOIP payload of the VOIP datagram, the quality of the VOIP payload, requested data rates for subsequent VOIP datagrams, and whether the VOIP payload contains a “silent” VOIP payload. To avoid conflicting with particular datagram requirements, the control information is inserted into the VOIP datagram between the VOIP datagram and the VOIP payload. A base station servicing the wireless link may override the requested data rate and/or the commanded data rate in order to manage its available wireless bandwidth among a plurality of mobile stations. The frame quality indicator may be set by the servicing physical/mac/link layer(s) of the base station or mobile station to indicate that the VOIP payload was not correctly received.

The first relay device is configured to select the first set of network use parameters from network resources available for communicating over the wireless relay node network based, at least in part, on a control signal received from the second relay device.

摘要： The invention is a novel method enabling a base station receiver to quickly and accurately validate a coded digital verification color code (CDVCC) vector received from a mobile station against a locally stored CDVCC vector identifying the cell to which it belongs. At the base station receiver, the received signal is sampled at twice the transmitted symbol rate, producing complex-valued samples of the received symbol envelope. These contain the received CDVCC vector and a known SYNC vector, and are assumed to have undergone dispersion characterized by several dispersion coefficients. The SYNC vector is detected with relative ease, allowing the establishment of a reference sample time. This is followed by the receiver determining a plurality of possible starting times (or “shifts”) for the CDVCC vector relative to the reference sample time. These shifts preferably cover the time advances or delays that the CDVCC vector may have undergone due to dispersion, relative to the position of the SYNC vector as detected. For each of the possible shifts, the dispersion coefficients are estimated a number of times and a metric is derived, which is a measure of the variation in the estimates of the dispersion coefficients. Since the dispersion coefficients are not expected to change significantly throughout the duration of the CDVCC, a low value for the metric should be reached when the received CDVCC vector matches the locally stored CDVCC vector for at least one of the possible CDVCC vector shifts.
摘要翻译：本发明是一种新颖的方法，使得基站接收机能够快速且准确地验证从移动台接收的编码数字验证色码（CDVCC）向量，以抵抗标识其所属小区的本地存储的CDVCC向量。在基站接收机处，接收到的信号以传输的符号速率的两倍进行采样，产生接收到的符号包络的复值采样。它们包含接收到的CDVCC载体和已知的SYNC载体，并且假设已经经历了以几个色散系数为特征的色散。相对容易地检测到SYNC矢量，允许建立参考采样时间。接下来是接收机确定CDVCC矢量相对于参考采样时间的多个可能的开始时间（或“移位”）。这些偏移优选地覆盖相对于检测到的SYNC向量的位置，CDVCC向量可能由于分散而经历的时间进度或延迟。对于每个可能的移位，估计色散系数的次数，并且导出度量，其是色散系数的估计中的变化的量度。由于在CDVCC的整个持续时间内不期望色散系数显着改变，所以当所接收的CDVCC矢量与本地存储的CDVCC矢量与可能的CDVCC矢量移位中的至少一个相一致时，应该达到该度量的低值。
