Multi-channel setup mechanisms and waveform designs for millimeter wave (mmW) systems
Mechanisms may be used for multi-channel (MC) setup and access and waveform designs for millimeter wave (mmW) systems. An access point (AP) that is part of a basic service set (BSS) may provide multi-channel (MC) access to one or more stations (STAs) in the BSS. The AP may monitor for beacon frames transmitted by other access point/personal basic service set (PBSS) control point (AP/PCP) associated with overlapping basic service sets (OBSSs). The monitored beacon frames may include service period (SP) scheduling information for the OBSS. The AP may generate an allocations at least one SPs and/or contention based access periods (CBAPs) channels to be used in a beacon interval in consideration of the SP scheduling information for the OBSS. The AP may transmit a beacon frame STA(s) indicating the SP/CBAP allocations. Other mechanisms may include simultaneous transmission of multiple single carrier (SC) waveforms with non-overlapping waveforms to multiple STAs.
