Abstract

A method and apparatuses for operation in a shared spectrum (SS) among a primary user (PU) and other users are disclosed. An access point (AP) or station (STA) may determine that a primary user is using SS frequency and only a portion of an 802.11 channel is available for AP/STA use. The AP may receive spectrum usage information of a PU from a database and transmit this information to a STA. The AP and STA may determine PU usage based on the information and change to a fractional spectrum mode. Based on PU usage, the AP and STA may adjust transmissions to suppress subcarriers used by the PU, including subcarriers in an SS-preamble, an SS short orthogonal frequency division multiplexing (OFDM) training field (SS-STF) symbol and an SS long OFDM training field (SS-LTF) symbol, and may reduce the physical (PHY) Layer Convergence Protocol (PLCP) Service Data Unit (PSDU) size.
