摘要： Methods of reverse link power control are provided. In a first example reverse link power control process, a signal-to-interference+noise (SINR) is measured for a plurality of mobile stations. A power control adjustment is determined for each of the mobile stations based on the measured SINR for the mobile station and a fixed target SINR, the fixed target SINR being used in the determining step for each mobile station and sending the power control adjustments to the mobile stations. In a second example reverse link power control process, one or more signals are transmitted to a base station. A power control adjustment indicator indicating an adjustment to a transmission power level is received. The received power control adjustment is determined based on a measured signal-to-interference+noise ratio (SINR) for the one or more transmitted signals and a fixed target SINR threshold, the fixed target SINR threshold being used for power control adjustment of a plurality of mobile stations.

摘要： Disclosed is an Orthogonal Frequency Division Multiple Access (OFDMA) based wireless communications system operable to communicate OFDMA type signals over a set of dynamically assigned orthogonal sub-carriers and Code Division Multiple Access (CDMA) type signals over a set of pre-allocated orthogonal sub-carriers. The OFDMA system utilizes pre-allocated orthogonal sub-carriers for CDMA type signal transmission in order to reduce the number of dynamic assignments of orthogonal sub-carriers in a typical OFDMA system. The OFDMA type signals may be signals processed in accordance with well-known OFDMA techniques, whereas the CDMA type signals may be signals processed in accordance with well-known CDMA and OFDMA techniques. The CDMA type signals may also be processed using a pre-coder incorporating a Discrete Fourier Transformer (DFT) matrix or Identity matrix to reduce the Peak-to-Average Power Ratio across the OFDMA system.

摘要： In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known à priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

摘要： A frequency offset estimation is generated without explicitly generating a channel estimation for a frequency selective fading communication channel. This is realized by recognizing that, in the absence of additive noise, the channel output at a time n depends only on the last previous predetermined number, L, of data symbols, and that a “state” is a sequence of the last L symbols. Specifically, in a receiver, a received signal is mixed with a locally generated frequency corresponding to a frequency offset to generate a mixed signal. A calculation is made on the mixed signal in which channel outputs of the same state are combined and accumulated. Then, a summation is made over all possible states of the combined and accumulated channel outputs to yield a so-called metric calculation value for that mixed signal. The metric calculation is then repeated for a plurality of different locally generated frequencies corresponding on a one-to-one basis with a plurality of frequency offsets. The frequency offset corresponding to the largest metric calculation value is selected as the desired frequency offset estimate. In one embodiment of the invention, a representation of a frequency offset estimation value is obtained by employing an open loop arrangement. In another embodiment of the invention, a frequency offset estimation value is generated by employing an closed loop arrangement.
摘要翻译：在频率选择性衰落通信信道的频道估计中不产生频偏估计。这通过认识到在没有加性噪声的情况下，在时间n处的信道输出仅取决于数据符号的最前一个预定数量L，并且“状态”是最后的L个符号的序列。具体地说，在接收机中，将接收到的信号与对应于频率偏移的本地产生的频率混合以产生混合信号。对相同状态的通道输出进行组合和累加的混合信号进行计算。然后，对组合和累积的信道输出的所有可能状态进行求和，以产生用于该混合信号的所谓度量计算值。然后针对多个频率偏移在一对一的基础上对多个不同的本地生成的频率重复度量计算。选择与最大度量计算值相对应的频率偏移作为期望的频率偏移估计。在本发明的一个实施例中，通过采用开环布置来获得频率偏移估计值的表示。在本发明的另一实施例中，通过采用闭环布置来产生频率偏移估计值。

摘要： A metric of cell congestion is determined using an average physical resource block rate that is expected to be allocated for a very active user equipment bearer that is a persistent average rate. The average physical resource block rate is mapped to congestion levels and this information is exported to an application function or a radio access network function in order to mitigate congestion. An average bearer throughput for the user equipment can be calculated based on the average physical resource block rate.
