摘要： In wireless communications, an access point may send a first frame to multiple stations. In one aspect, the first frame may include resource allocation information for uplink multi-user transmission. In response to the first frame, one or more stations may measure the channel characteristics associated with the first frame and send a second frame(s) for uplink multi-user transmission, where the second frame(s) includes resource preference information associated with the respective station(s). The access point may then generate and transmit a third frame based on the resource preference information. In another aspect, in response to the first frame, one or more stations may send a second frame(s) spanning the channel bandwidth supported by the respective station(s). The access point may measure the channel characteristics associated with the second frame and generate and transmit a third frame based on the measured channel characteristics. Other methods, apparatus, and computer-readable media are also disclosed.

摘要： In an example of wireless communications, an access point may send a downlink frame to multiple stations. The downlink frame may include information indicative of a cyclic prefix length to be utilized by the stations. In response, some or all of the stations may transmit their respective uplink frames to the access point. A cyclic prefix for a portion of each respective uplink frame may have a cyclic prefix length corresponding to the information included in the downlink frame. The downlink frame may be, for example, a beacon frame or a trigger frame. A trigger frame may allocate resources for uplink orthogonal frequency division multiple access (OFDMA) transmission. Other methods, apparatus, and computer-readable media are also disclosed.

摘要翻译：在无线通信中，接入点可以将第一帧发送到多个站。在一个方面，第一帧可以包括用于上行链路多用户传输的资源分配信息。响应于第一帧，一个或多个站可以测量与第一帧相关联的信道特性并发送用于上行链路多用户传输的第二帧，其中第二帧包括与该第一帧相关联的资源偏好信息各自的车站。然后，接入点可以基于资源偏好信息生成并发送第三帧。在另一方面，响应于第一帧，一个或多个站可以发送跨越各个站所支持的信道带宽的第二帧。接入点可以测量与第二帧相关联的信道特性，并且基于所测量的信道特性生成和发送第三帧。还公开了其它方法，装置和计算机可读介质。

摘要翻译：在无线通信的示例中，接入点可以向多个站发送下行链路帧。下行链路帧可以包括指示站要使用的循环前缀长度的信息。作为响应，一些或所有站可以将它们各自的上行链路帧发送到接入点。每个相应上行链路帧的一部分的循环前缀可以具有与包括在下行链路帧中的信息相对应的循环前缀长度。下行链路帧可以是例如信标帧或触发帧。触发帧可以为上行链路正交频分多址（OFDMA）传输分配资源。还公开了其它方法，装置和计算机可读介质。
