1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
send a multiuser location trigger frame to two or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase, wherein a subtype of the multiuser location trigger frame is set to “poll”;
assign, in the multiuser location trigger frame during the polling phase, a first resource unit (RU) to a first ISTA of the two or more ISTAs on a first frequency bandwidth;
assign, in the multiuser location trigger frame during the polling phase, a second RU to a second ISTA of the two or more ISTAs on a second frequency bandwidth, wherein the second frequency bandwidth is different from the first frequency bandwidth to allow the first ISTA and the second ISTA to be assigned their respective frequency bandwidth without contending when sending their corresponding clear to send (CTS) frames;
receive, during the polling phase, a first CTS frame from the first ISTA, wherein receiving the first CTS indicates a first request to participate in a ranging measurement;
identify, during the polling phase, a second CTS frame received from the second ISTA, wherein receiving the second CTS indicates a second request to participate in the ranging measurement;
identify the first ISTA based on a first resource unit (RU) in which the first CTS frame was received; and
identify the second ISTA based on a second RU in which the second CTS frame was received.
