摘要： A multi-resolution codebook is used to provide quantization for channel related information in a wireless network that supports both single-user MIMO and multi-user MIMO. The multi-resolution codebook may include a higher resolution "fine" codebook for use with MU-MIMO subscriber stations and a lower resolution "coarse" codebook for use with SU-MIMO subscriber stations. A tracking codebook may also be used to provide quantization for updates to channel related information. In at least one embodiment, the tracking codebook includes a number of unit vectors (or orthogonal matrices) disposed upon a sphere cap.

摘要： In various embodiments of the invention, a relay station in a wireless communications network may communicate with one or more subscriber stations at the same time and/or on the same frequency that the associated base station is communicating with another relay station in the same network. This contrasts with the conventional technique of devoting one time period or frequency exclusively to communications between the base station and the relay stations, and devoting another time period or frequency exclusively to communications between the relay stations and the subscriber stations.

摘要： Techniques are disclosed that involve communicating in bursty noise environments. For instance, a source device may send a probing packet to a destination device. This probing packet is for determining whether the communications medium (e.g., one or more frequency channels) is currently exhibiting a busy or jammed (e.g., due to bursty noise) condition. More particularly, based on whether an acknowledgment of the probing packet is received, the source device determines whether the channel is jammed (or busy) or clear. For example, an unacknowledged probing packet indicates that the channel is jammed or busy, while an acknowledged probing packet indicates that the channel is clear. If the channel is determined to be clear, then the source device may transmit one or more data packets to the destination device. Such data packet transmissions may be in accordance with a non rate-adaptive technique.
摘要翻译：公开了涉及在突发噪声环境中通信的技术。例如，源设备可以向目的地设备发送探测分组。该探测分组用于确定通信介质（例如，一个或多个频率信道）当前是否正在呈现忙或卡住（例如，由于突发噪声）条件。更具体地，基于是否接收到探测分组的确认，源设备确定信道是否被卡住（或忙）或清除。例如，未确认的探测分组指示信道被卡住或占线，而确认的探测分组指示信道是清除的。如果信道被确定为清除，则源设备可以向目的设备发送一个或多个数据分组。这种数据分组传输可以是根据非速率自适应技术。

摘要： Embodiments of a communication station and methods for efficiently providing channel feedback for MIMO communications over an OFDM channel are generally described herein. In some embodiments, receiving stations may perform a recursive differential quantization of channel information across time and/or frequency to generate quantized differential channel feedback. The quantized differential channel feedback from each receiving station may be used by a transmitting station to precode MIMO transmissions to one or more of the receiving stations. The quantized differential channel feedback may be either a quantized differential channel matrix or a quantized differential beamforming matrix.

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：公开了重传技术。这些技术可以用于采用基于竞争的接入方案的网络，例如CSMA。例如，设备可以从发送设备接收损坏的分组，并确定损坏的原因。当确定的损坏原因是网内分组冲突时，设备允许发送设备根据基于竞争的访问方案发送分组的重传。然而，当确定的损坏原因不是网络内的分组冲突时，设备向发送设备提供重新发送协助。该重传协助可以包括用于重传的信道预留，和/或用于传送设备的一个或多个链路自适应建议。
