摘要： The present invention provides a method for supplying unicast and multicast transmissions to a plurality of mobile devices in a wireless system. The method comprises supplying a multicast signal using a first portion of total available power, wherein the first portion of total available power is a function of a channel quality indicator associated with at least one of the mobile devices. Thereafter, a unicast signal is supplied using a second portion of total available power, wherein the second portion of total available power is a function of the first portion of total available power.

摘要： Signals are developed for use in a wireless system with multiple transmit and multiple receive antennas so that even in the face of some correlation the most open-loop capacity that can be achieved using a substantially open-loop system with a channel of that level of correlation is obtained. In accordance with the principles of the invention, the signals transmitted from the various antennas are processed so as to improve their ability to convey the maximum amount of information. More specifically, the data to be transmitted is divided into M+1 substreams, where M is the number of transmit antennas. Each transmit antenna is supplied with a combination signal that is made up of a weighted version of a common one of the substreams and a weighted version of a respective one of the substreams that is supplied uniquely for that antenna, so that there are M transmit signals. A receiver having N antennas receives the M transmit signals as combined by the channel and reconstitutes the original data therefrom. This may be achieved using successive decoding techniques. Advantageously, the capacity, i.e., the rate of information that can be conveyed with an arbitrarily small probability of error when the instantaneous forward channel condition is unknown to the transmitter, is maximized.
摘要翻译：信号被开发用于具有多个发射和多个接收天线的无线系统中，使得即使在某些相关性的情况下，也可以使用具有该相关级别的信道的基本开环系统来实现最大的开环容量获得。根据本发明的原理，对从各种天线发射的信号进行处理，以提高它们传达最大信息量的能力。更具体地，要发送的数据被划分为M + 1个子流，其中M是发射天线的数量。每个发射天线被提供有组合信号，该组合信号由子流中的公共一个的加权版本和为该天线唯一提供的子流中的相应一个的加权版本组成，使得存在M个发射信号。具有N个天线的接收机接收通过信道组合的M个发射信号并从其重构原始数据。这可以使用连续的解码技术来实现。有利地，当瞬时正向信道条件对于发射机是未知的时，容量，即可以以任意小的误差概率传送的信息的速率被最大化。

摘要： Power allocation methods for multiuser orthogonal frequency division multiplexing (OFDM) are described. Arbitrary partitioning of the OFDM tones among users and arbitrary modulation formats, possibly different for every user, are considered. Two systems of receivers and transmitters and corresponding methods address power allocation, respectively for slow fading channels tracked instantaneously by the system and for fast fading channels known only statistically thereby.

摘要： In a wireless communication system using multiple antennas at the transmitter and multiple antennas at the receiver, with a sufficiently large number of antennas and/or diversity order, the same performance that is obtainable when employing instantaneous rate indication feedback can be attained without any such short-term feedback by adjusting the data rate of each transmit antenna according to a prescribed function. The prescribed function does not depend on the short-term state of the channel, but instead only depends on its long-term statistics, which may be fed back from the receiver to the transmitter at relatively lengthy intervals.
