Techniques for determining a symbol period for a starting symbol of a transmission in a shared radio frequency spectrum

摘要

Techniques are described for wireless communication. A first method includes monitoring, by a first wireless device, at least one predetermined symbol period of a subframe for an indication that a second wireless device has obtained access to a shared radio frequency spectrum; determining a starting symbol for a transmission by the second wireless device over the shared radio frequency spectrum based on detecting the indication; and receiving the transmission by the second wireless device over the shared radio frequency spectrum based on the determined starting symbol.
