摘要： Methods and structures are disclosed for use in implementing downlink spatial division multiple access (SDMA) in a wireless network. In at least one embodiment, a number of orthogonal sets of user devices are first identified within a coverage area. One of the identified orthogonal sets may then be selected based on a predetermined selection criterion. An SDMA exchange may then be initiated for the selected orthogonal set.

摘要： In Spatial Division Multiple Access (SDMA) communications, mobile devices that are transmitting to a base substantially simultaneously during a predetermined communications phase may wait until after an end of the predetermined communications phase to receive acknowledgments to their transmissions, so that a mobile device making a relatively short transmission does not experience an acknowledgement timeout while another mobile device is still completing a relatively long transmission. In some embodiments, the mobile devices may transmit a non-immediate block acknowledgement request during the communications phase.

摘要： An access point in a wireless network communicates with multiple mobile stations simultaneously using spatial-division multiple access. The access point transmits to the mobile stations frames that end at different times within a predefined window of time. When the predefined window in time is a short interframe space (SIFS) in an IEEE 802.11 compatible network, the access point will be done transmitting the frames in time to receive acknowledgements from the multiple mobile stations.

摘要： Techniques and structures are provided to support a short-NAV type wireless medium reservation scheme in a network that utilizes adaptive modulation techniques. The conventional long-NAV medium reservation technique uses a medium reservation period that reserves a wireless medium until the end of a present frame exchange. The short-NAV medium reservation technique, on the other hand, uses a medium reservation period that reserves the wireless medium until the end of the next transmission of the other communicating node involved in a frame exchange. In some embodiments, a short-NAV technique is provided where a medium reservation period is determined based upon a suggested data rate. If a device decides not to use the suggested data rate, the device may utilize packet fragmentation techniques to ensure that a subsequent data transmission does not exceed the specified medium reservation period.
摘要翻译：提供技术和结构以支持利用自适应调制技术的网络中的短NAV型无线介质预留方案。常规的长NAV介质预留技术使用保留无线介质的介质预留周期，直到当前帧交换结束。另一方面，短NAV媒体预约技术使用保留无线媒体的媒体预约期，直到涉及帧交换的其他通信节点的下次发送结束为止。在一些实施例中，提供了基于建议的数据速率来确定介质预留时段的短NAV技术。如果设备决定不使用建议的数据速率，则设备可以利用分组分片技术来确保后续数据传输不超过指定的介质预留时段。
