Abstract
Embodiments of the present invention provide for content optimization of a physical layer preamble. In one embodiment of the invention, a method for encapsulating a payload for transmission through a network is disclosed. The method comprises the step of programming a legacy physical layer length value in a legacy physical layer preamble. The legacy physical layer preamble is configured such that it can be received by any legacy stations that may be on the network, and such that a separate physical layer length value can be derived from the legacy physical layer preamble. Using such a system, content optimization of a physical layer preamble is provided.
Claims18
A method comprising:
- forming a packet for transmission on a network that operates under the IEEE 802.11ac standard, wherein the packet includes a payload, a legacy physical layer preamble and a separate physical layer preamble;
- configuring said legacy physical layer preamble to be properly received by legacy stations connected to the network;
- programming a legacy physical layer length value of the legacy physical layer preamble, wherein said legacy physical layer length value specifies a length of the payload and a length of the separate physical layer preamble combined, and wherein said legacy physical layer length value is configured so that a separate physical layer length value representing the length of the payload can be derived from said legacy physical layer length value, wherein the separate physical layer length value corresponds with a very high throughput-physical layer convergence protocol (VHT-PLCP) length value, and wherein the VHT-PLCP length value is derived from the legacy physical layer length value within a station receiving the packet;
- and
- transmitting the packet to the network.
A method comprising:
- receiving a packet from a network that operates under the IEEE 802.11ac standard, wherein the packet includes a payload, a legacy physical layer preamble and a separate physical layer preamble;
- and
- deriving a separate physical layer length value representing a length of the payload from a legacy physical layer length value of the legacy physical layer preamble, wherein said legacy physical layer length value specifies a length of the payload and the separate physical layer preamble combined, wherein the separate physical layer length value corresponds with a very high throughput-physical layer convergence protocol (VHT-PLCP) length value, and wherein the VHT-PLCP length value is derived from the legacy physical layer length value of the received packet, and wherein said legacy physical layer preamble is configured such that said legacy physical layer preamble can be properly received by a set of stations on the network, even if a legacy station is in said set of stations.
