Claim
1. Method of signalling a number of antenna ports of a transmitting node in a wireless communication system characterised in that a communication signal is transmitted carrying information on number of at least one antenna port of said transmitting node, wherein the information on said number of at least one antenna port is partitioned and provided distributed over at least two predefined parts of the transmitted communication signal.
2. The method according to claim 1, wherein a predefined first part of the communication signal refers to signalling of a first number of at least one antenna port and a predefined second part of the communication signal refers to signalling whether said transmitting node comprises a number of at least one antenna port in addition to the first number of at least one antenna port.
3. The method according to claim 2, wherein the first part of the communication signal comprises a first CRC mask, the first CRC mask corresponding to the first number of at least one antenna port.
4. The method according to claim 2, wherein the first number of at least one antenna port is 1, 2 or 4.
5. The method according to claim 3, wherein the second part of the communication signal comprises at least one explicit information bit of a CRC code anticipating systematic encoding.
6. The method according to claim 5, wherein one or more parity bits according to the CRC code are determined on a basis including said at least one explicit information bit.
7. The method according to claim 3, wherein the second part of the communication signal comprises a second CRC mask.
8. The method according to claim 7, wherein the first and second CRC masks are embedded into one and the same radio communications channel in different or alternating transmission time intervals.
9. The method according to claim 3, wherein the second part of the communication signal is transmitted on a channel different from the channel for transmission of the first communication signal, the different channel being transmitted on at least one of the antenna ports, the number of which is greater than zero and is indicated by the first part of the communication signal
10. The method according to any of claims 5-9, wherein the first part of the communication signal is transmitted on a physical broadcast channel, PBCH
11. The method according to any of claims 7-9, wherein each at least one antenna port is defined by a cell-specific downlink reference signal
12. The method according to clam 2, comprising', '- receiving the predefined first signal part;', '- receiving the predefined second signal part, and - determining from at least the detected second signal part the number of antenna ports to be included in subsequent processing
13. Computer program element, comprising code means, which when run in a computer causes said computer to execute procedure according to the method in any of claims 1-11
14. Computer program product comprising a computer readable medium having thereon computer program code means in claim 13, wherein said readable medium comprises one or more of ROM (Read-Only Memory), Flash memory, optical disk, electro-optical disk, magneto-optical disk, magnetic disk, electromagnetic disk, hard disk and soft disk
15. Transmission apparatus of a wireless communication system comprising', '- transmission circuitry comprising one or more antenna ports arranged for transmission of a communication signal; processing circuitry arranged for partitioning the number of antenna ports into a first number comprising a first number of antenna ports, and a second number; - processing circuitry arranged for providing the first number in a predetermined first part of a communication signal and for providing the second number in a second predetermined second part of the communication signal
16. The transmission apparatus according to claim 15 comprising processing circuitry arranged for the method in any of claims 2-11
17. Reception apparatus of a wireless communication system comprising receiving circuitry arranged for reception of a communication signal; processing circuitry arranged for determining from at least one part of received first and second predetermined parts of the communication signal a total number of transmission antenna ports to be applied in subsequent signal processing by the processing circuitry of the communication signal
18. The reception apparatus according to claim 17 comprising processing circuitry arranged for the method in any of claims 2-12.']
