Abstract
A scalable slot format defining positions of synchronization symbols pilot symbols and data symbols for various numbers of sub-channels and various lengths of time in a multi-carrier communication system. An initial pattern ( 500) and one or more follow-on patterns ( 600 700) are defined identifying positions of data symbols synchronization symbols and pilot symbols for a first number of sub-channels corresponding to a first bandwidth. An extended pattern is constructed from the one or more follow-on patterns. The extension pattern is appended to the initial pattern to form a base pattern ( 810 910 1010). The base pattern ( 810 910 1010) is replicated zero or more times to form an expanded pattern ( 812 910 1015) identifying positions of data symbols synchronization symbols and pilot symbols for an expanded number of sub-channels corresponding to a second bandwidth. The slot format may be implemented by a transmitter ( 100) having subdivided an original information signal into M bit streams and having encoded each of the M bit streams to 16QAM symbols to form M symbol streams by inserting synchronization and pilot symbols into each of the M symbol streams at positions determined by the expanded pattern.
