Millimeter wave beaconing with directional antennas
First Claim
1. A method of communication, comprising:
- transmitting a first beacon signal via a set of quasi-omni beam patterns; and
transmitting a second beacon signal via a set of directional beam patterns, wherein a first rate associated with the transmission of the first beacon signal is higher than a second rate associated with the transmission of the second beacon signal, and whereinthe first rate is a function of Golav code length and number of Golav code repetitions used in a preamble of the first beacon signal, and the second rate is a function of Golay code length and number of Golay code repetitions used in a preamble of the second beacon signal.

Abstract
A wireless device comprises a code-assignment module configured for assigning Golay codes to be used for spreading, a spreading module configured for spreading data with the Golay codes to produce a signal, wherein the Golay codes are randomly used to spread the data, and a transmitter configured for transmitting the signal. The wireless device may transmit a first beacon signal via a set of quasi-omni beam patterns, and a second beacon signal via a set directional beam patterns. The first beacon signal has a first transmission rate that is higher than the second beacon signal'"'"'s the transmission rate. Extended Golay codes having zero periodic cross-correlation may be generated from a Golay code and a set of short sequences. A data block transmitted by the wireless device may comprise Golay codes and data portions, wherein every data portion is between two Golay codes and every Golay code is between two data portions.
