摘要： A first communication device prompts a plurality of second communication devices to transmit, during a contiguous time period reserved for a range measurement exchange, respective first null data packets (NDPs) at respective times. The first communication device receives first NDPs from at least some of the second communication devices during the contiguous time period, and transmits one or more second NDPs to the plurality of second communication devices. The first communication device uses reception of the first NDPs and transmission of the one or more second NDPs to determine respective ranges between the first communication device and respective second communication devices.

摘要： In a method of providing channel state information determined at a second communication device to a first communication device, a channel estimate matrix H describing a forward communication channel between the first communication device and the second communication device is determined at the second communication device (1202). Feedback descriptive of the forward communication channel is determined based on the channel estimate matrix H at the second communication device (1204). When operating in a multi user mode or in a single user mode and with multiple spatial streams, full compressed feedback is generated (1206). Full compressed feedback includes a set of φ angle values and a set of Ψ angle values corresponding to each of one or more columns of the channel estimate matrix. When operating in the single user mode and with a single spatial stream, partial compressed feedback is generated (1208). Partial compressed feedback includes a set of φ angle values, and omits a set of Ψ angle values, corresponding to the channel estimate matrix. The feedback is transmitted from the second communication device to the first communication device (1210).
