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.
Claims21
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.
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.
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.
