Claim Text:
1. A reference signal sending method, used in a long term evolution (LTE) network, comprising: determining, by a network node, ports and number of layers used for transmitting downlink specific reference signals to user equipment; generating, by the network node, downlink control signaling according to the ports and the number of layers, wherein 5-bits signaling in the downlink control signaling is used to indicate the user equipment the ports and the number of layers used for transmitting the downlink specific reference signals, in order to support multiplexing of at most eight user equipment; and sending, by the network node, the downlink control signaling to the user equipment, and sending the downlink specific reference signals to the user equipment according to the determined ports and the number of layers, to enable the user equipment to receive the downlink specific reference signals according to the downlink control signaling, wherein the downlink control signaling further comprises one bit of signal to indicate a scrambling identity, in order to support multiplexing of at most sixteen user equipment, and wherein the ports indicated by the 5-bits signaling are antenna ports 7 to 14 defined in LTE R10.
