Abstract:
During a service period (SP) for a ranging measurement signal exchange between a first communication device and one or more second communication devices, the first communication device receives respective first null data packets (NDPs) from the one or more second communication devices, and transmits respective second NDPs to the one or more second communication devices. The first communication device transmits, during the SP, respective first ranging measurement feedback packets to the one or more second communication devices to allow each of the one or more second communication devices to determine a time-of-flight between the first communication device and the second communication device and/or receives, during the SP, respective second ranging measurement feedback packets from the one or more second communication devices to allow the first communication device to determine respective times-of-flight between the first communication device and the one or more second communication devices.

Claim (Index 11):
An apparatus, comprising:\n a network interface device associated with a first communication device, wherein the network interface device includes one or more integrated circuits (ICs) configured to:\n receive, during a service period (SP) for a ranging measurement signal exchange between the first communication device and one or more second communication devices, respective first null data packets (NDPs) from respective one or more second communication devices, \n transmit, during the SP, respective second NDPs to the respective one or more second communication devices, and \n one or both of\n i) transmit, during the SP, respective first ranging measurement feedback packets to the one or more second communication devices, the respective first ranging measurement feedback packet transmitted to a particular second communication device including at least a) an indication corresponding to a time t 2  at which the respective first NDP was received from the particular second communication device and b) an indication corresponding to a time t 3  at which the respective second NDP was transmitted to the particular second communication device to allow the particular second communication device to determine a time-of-flight between the first communication device and the particular second communication device, and \n ii) receive, during the SP, respective second ranging measurement feedback packets from the one or more second communication devices, the respective second ranging measurement feedback packet from a particular second communication device including at least a) an indication corresponding to a time t 1  at which the respective first NDP was transmitted by the particular second communication device, and b) an indication corresponding to a time t 4  at which the respective second NDP was received by the particular second communication device to allow the first communication device to determine a time-of-flight between the first communication device and the particular second communication device.
