Preamble Detection on a Communication Channel |
| 摘要 |
Described herein are apparatuses for receiving preamble information via a channel between a first device and a second device. An apparatus is configured to scan a band of multiple carriers associated with the channel, determine a first carrier associated with the channel from the band of multiple carriers, wherein a first channel quality metric associated with the first carrier is greater than a threshold channel quality metric, receive, on the first carrier, the preamble information from the first device, determine a second carrier associated with the channel from the band of multiple carriers, wherein a second channel quality metric associated with the second carrier is greater than the threshold channel quality metric, receive, on the second carrier, the preamble information from the first device, and determine, based on receipt of the preamble information from the first device, a start of a data packet transmission from the first device. |

1. An apparatus for receiving preamble information via a channel at a second device from a first device, the apparatus comprising:
an I/O module; and
a processor coupled to the I/O module, the processor configured to:scan a band of multiple carriers associated with the channel;determine a first carrier associated with the channel from the band of multiple carriers associated with the channel, wherein a first channel quality metric associated with the first carrier is greater than a threshold channel quality metric;receive, on the first carrier, the preamble information from the first device;determine a second carrier associated with the channel from the band of multiple carriers associated with the channel, wherein a second channel quality metric associated with the second carrier is greater than the threshold channel quality metric;receive, on the second carrier, the preamble information from the first device; anddetermine, based on the receipt of the preamble information on the first carrier and the second carrier, a start of a data packet transmission from the first device. |
