摘要： Embodiments of an OFDM transmitter and method of reducing the effects of interference on subcarriers in an OFDM system by symbol loading are disclosed herein. A linear transformation is performed on a group of two or more input data symbols that are mapped to different signal dimensions to generate a corresponding two or more output data symbols. Each of the output data symbols has an increased number of constellation points. Each output data symbol is configured for transmission within one of the different signal dimensions. The linear transformation is configured so that each of the two or more output data symbols carry the information of each of the input data symbols of the group. This coding together of input data symbols that are mapped to different signal dimensions may provide improved reliability against fading and severe interference. The different signal dimensions may comprise a frequency, a time and/or a space dimension.

摘要： Retransmission techniques are disclosed. These techniques may be used in networks employing contention-based access schemes, such as CSMA. For instance, a device may receive a corrupted packet from a transmitting device, and determine a cause of the corruption. When the determined cause of the corruption is an in-network packet collision, the device allows the transmitting device to send a retransmission of the packet in accordance with a contention-based access scheme. However, when the determined cause of the corruption is other than an in-network packet collision, the device provides retransmission assistance to the transmitting device. This retransmission assistance may include a channel reservation for a retransmission, and/or one or more link adaptation suggestions for the transmitting device.
摘要翻译：披露重传技术。这些技术可以用于采用基于争用的接入方案的网络，例如CSMA。例如，设备可以从发送设备接收损坏的分组，并且确定损坏的原因。当所确定的损坏的原因是网络内分组冲突时，设备允许发送设备根据基于竞争的接入方案发送分组的重传。然而，当所确定的损坏的原因不是网内分组冲突时，设备向发送设备提供重传协助。该重传辅助可以包括用于重发的信道预留和/或用于发送设备的一个或多个链路适配建议。

摘要： Methods and apparatuses for providing CQI feedback with common code rate to a transmitter station are described herein. In one implementation, the methods may include a receiver station that is communicatively linked to a transmitter station via k spatial channels transmitting a first CQI to the transmitter station that indicates a modulation level for use by the transmitter station to transmit (i.e., to configure for transmission) a first of k streams of signals to be transmitted to the receiver station. The first CQI may further include a common code rate to be used by the transmitter station for transmitting the first of the k streams of signals as well as for transmitting the rest of the k-1 additional streams of signals to the receiver station. The receiver station may further transmit to the transmitter station k-1 additional CQIs to indicate to the transmitter station the k-1 modulation levels to be used by the transmitter station for transmitting the k-1 additional streams of signals to the receiver station.
