Abstract: Mobile devices implement a ranging mechanism that includes a lead responder receiving ranging measurement requests from two different initiators in the same DW cycle. At the beginning of the DW cycle the lead responder broadcasts and/or publishes a channel availability map that includes a list of slots and channels in which to respond to the ranging measurement requests based on a number of ranging operations supported in each slot within the DW cycle and based on an autonomously determined response sequence. If the lead responder responds to all ranging requests by all initiators in a DW cycle, secondary responders can perform ranging in the same or subsequent DW cycles. Upon exhausting all initiators paired with the lead responder, a secondary responder becomes the “active” responder that is chosen based on a prioritization scheme that is universal among the group of devices in the ranging operation.

Abstract: Transmission techniques using configurable channels for the downlink and/or uplink are described. In one aspect, the downlink channel and/or uplink channel may be independently selected for a terminal. The terminal may establish a connection with a base station on default downlink and uplink channels. Another downlink channel and/or another uplink channel may be selected based on various factors such as channel quality, loading, and interference. The terminal would then switch to the new downlink and/or uplink channel for communication. In another aspect, the base stations broadcast sector information used by the terminals for communication and/or channel selection. The sector information may include various types of information such as the available downlink and uplink channels, the frequencies of the available channels, the loading on the available channels, and QoS information. The terminals may select a sector, a downlink channel, and/or an uplink channel based on the sector information
