1. A method of wireless communication, comprising:
- generating a frame comprising a physical layer preamble having a signal field, the signal field comprising;
an indicator indicating the signal field is encoded with multiple fields comprising information associated with a frame type; and
a cyclic redundancy check field;
encoding the multiple fields comprising information associated with the frame type in the signal field of the frame, the information comprising;
type information indicating the frame type; and
additional information determined based on frame type,wherein the frame type is at least one of a set of frame types, the set comprising;
an acknowledgement frame;
a power save poll frame;
a clear to send frame; and
a block acknowledgement frame; and
transmitting the frame.
