Abstract
A quantity of antenna ports of a transmitting apparatus is signalled in a wireless communication system. The quantity of antenna ports of the transmitting apparatus is encoded into a first type information and a second type information. The first type information is transmitted on a physical broadcast channel (PBCH) and the second type information is transmitted on a physical downlink shared channel (PDSCH). The PDSCH is transmitted on at least one antenna port indicated by the first type information.

Claim
1. A method of signaling a quantity of antenna ports of a transmitting apparatus in a wireless communication system, the method comprising:
transmitting, by the transmitting apparatus, a first type information on a physical broadcast channel (PBCH), wherein the first type information indicates a first number of an antenna port of the transmitting apparatus corresponding to a cell-specific reference signal (CRS); and
transmitting, by the transmitting apparatus, a second type information on a physical downlink shared channel (PDSCH), wherein the second type information indicates a second number of an antenna port of the transmitting apparatus corresponding to a channel state information reference signal (CSI-RS), wherein the PDSCH is transmitted on an antenna port indicated by the first type information.
2. The method of claim 1, wherein the first type information is detectable to both a long term evolution user equipment (LTE UE) and a long term evolution-advanced user equipment (LTE-A UE).
3. The method of claim 2, wherein the second type information is only detectable to the LTE-A UE.
4. The method of claim 1, wherein the first type information indicates the first number of the antenna port of the transmitting apparatus corresponding to the CRS being one, two, or four.
5. The method of claim 1, wherein the second type information indicates the second number of the antenna port of the transmitting apparatus corresponding to the CSI-RS being zero, two, four, or eight.
6. The method of claim 1, wherein the first type information is used for demodulating a control channel.
7. The method of claim 1, wherein the second type information is used for channel measurement.
8. The method of claim 1, wherein the transmitting apparatus supports more than four layers transmission.
9. The method of claim 1, wherein the transmitting apparatus is a base station.
10. A transmitting apparatus, comprising at least one processor configured to:
transmit a first type information on a physical broadcast channel (PBCH), wherein the first type information indicates a first number of an antenna port of the transmitting apparatus corresponding to a cell-specific reference signal (CRS); and
transmit a second type information on a physical downlink shared channel (PDSCH), wherein the second type information indicates a second number of an antenna port of the transmitting apparatus corresponding to a channel state information reference signal (CSI-RS), the PDSCH configured to be transmitted on an antenna port indicated by the first type information.
11. The transmitting apparatus of claim 10, wherein the first type information is detectable to both a long term evolution user equipment (LTE UE) and a long term evolution-advanced user equipment (LTE-A UE).
12. The transmitting apparatus of claim 11, wherein the second type information is only detectable to the LTE-A UE.
13. The transmitting apparatus of claim 10, wherein the first type information indicates the first number of the antenna port of the transmitting apparatus corresponding to the CRS being one, two, or four.
14. The transmitting apparatus of claim 10, wherein the second type information indicates the second number of the antenna port of the transmitting apparatus corresponding to the CSI-RS being zero, two, four, or eight.
15. The transmitting apparatus of claim 10, wherein the first type information is configured to be used for demodulating a control channel.
16. The transmitting apparatus of claim 10, wherein the second type information is configured to be used for channel measurement.
17. The transmitting apparatus of claim 10, wherein the transmitting apparatus supports more than four layers transmission.
18. The transmitting apparatus of claim 10, wherein the transmitting apparatus is a base station.
19. A wireless communication system, comprising a transmitting apparatus and a receiving apparatus, wherein the transmitting apparatus comprises at least one processor configured to:
transmit a first type information to the receiving apparatus on a physical broadcast channel (PBCH), wherein the first type information indicates a first number an antenna port of the transmitting apparatus corresponding to a cell-specific reference signal (CRS); and
transmit a second type information to the receiving apparatus on a physical downlink shared channel (PDSCH), wherein the second type information indicates a second number of an antenna port of the transmitting apparatus corresponding to a channel state information reference signal (CSI-RS), the PDSCH being transmitted on an antenna port indicated by the first type information.
20. The system of claim 19, wherein the first type information indicates the first number of the antenna port of the transmitting apparatus corresponding to the CRS being one, two, or four.
21. The system of claim 20, wherein the second type information indicates the second number of the antenna port of the transmitting apparatus corresponding to the CSI-RS being zero, two, four, or eight.
