Abstract
Aspects of a method and system for carrier sense multiple access with collision avoidance (CSMA/CA) with directional transmission are presented. Aspects of the system may include a communicating device (DEV), which transmits a portion of a PDU utilizing omnidirectionally transmitted signals and a subsequent portion of the PDU utilizing directionally transmitted signals. In an exemplary system the communicating DEV may transmit a frame, which represents a physical layer PDU. The frame may comprise a physical layer convergence procedure (PLCP) preamble that is transmitting utilizing omnidirectionally transmitted signals (omni preamble), a PLCP header that is transmitted utilizing omnidirectionally transmitted signals (omni header), a PLCP preamble that is transmitted utilizing directionally transmitted signals (directional preamble) and a physical layer service data unit (PSDU) field, or data, field, which is transmitted utilizing directionally transmitted signals (directional data). In another exemplary system, the communicating DEV may transmit PDUs utilizing directional signal transmission.
