FOR FURTHER ACTION: See Form PCT/ISA/220 as well as, where applicable, item 5 below.
This international search report has been prepared by this International Searching Authority and is transmitted to the applicant according to Article 18. A copy is being transmitted to the International Bureau.
It is also accompanied by a copy of each prior art document cited in this report.
1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
b.
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
c.
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
4. Title of the invention
The text is approved as submitted by the applicant.
The text has been established by this Authority to read as follows:
SIGNALING AND DETECTION OF A TRANSMITTER IDENTIFIER IN A BROADCAST TRANSMISSION NETWORK

5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

For ATSC 3.0, a frame comprises bootstrap OFDM symbols, having known universal OFDM parameters, followed by a preamble and payload data, which may have different OFDM characteristics. In the context of ATSC, the present application proposes to insert a transmitter identifier (TxID) within this frame structure. In SFN networks, such a TxID enables a receiver to adapt antennas orientation, or can improve network synchronization between nodes, or be used to derive the receiver location. Two options for said TxID insertion are proposed: The first option makes use of an additional fifth bootstrap symbol conveying the TxID instead of the conventional signaling information. The second option uses an additional OFDM symbol immediately prior or after the preamble, said additional OFDM symbol being generated similarly to the bootstrap symbol, except that the PN sequence is replaced by a Gold sequence uniquely determined by the TxID. At the receiver, TxID detection can be performed either using time domain or frequency domain code correlation.


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     14    
as suggested by the applicant.
