Abstract
A method of auto-detection of WLAN packets includes selecting a first Golay sequence from a first pair of Golay complementary sequences associated with first packet type, each Golay sequence of the first pair of Golay complementary sequences being zero correlation zone (ZCZ) sequences with each Golay sequence of a second pair of Golay complementary sequences associated with a second packet type, and transmitting a wireless packet carrying a short training field (STF) that includes one or more instances of the first Golay sequence.
Claims24
A wireless device comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing instructions that, when executed by the at least one processor, cause the wireless device to perform operations including:
- transmitting in a 60 GHz frequency band a wireless packet, the wireless packet comprising a first header and a second header, the first header carrying a plurality of bits, a logical value of a subset of the plurality of bits in the first header indicating presence of the second header in the wireless packet, both of the first header and the second header being physical layer packet headers, the first header carrying a first parameter for an IEEE 802.11ad packet type, the second header carrying a second parameter for an IEEE 802.11ay packet type, the second parameter indicating a number of bonded channels, wherein channel bonding is not supported by the IEEE 802.11ad packet type.
