Methods and devices related to flag and signalling of synchronization of broadband compounds.

摘要

b methods and equipment related to the flag and signalling of synchronization of broadband d a compound compound signal includes a signal of high power signals and sync signal of broadband corresponding low power and is communicated through a int Ervalo time exceeding a single time interval of OFDM transmission.A base station transmits one or more of such signs of broadcast different compounds in a timing structure of applicant. Each signal signalling in different potential, for example, a single tone signal, is paired with a sync signal of broadband, exclusive.A broadband sync signal includes at least some predetermined null tones and at least some tones not nulospredeterminados. For a given signal synchronization of broadband, the predetermined null tones containing values of predetermined modulation symbol.A wireless terminal receives a composite signal, identifies a beacon provides a sync signal of broadband known corresponding compares synchronization signals received with known broadband, and determining at least one between an adjustment of timing, adjustment of F. While making fastenings and estimation of channel.
