Abstract:
1. A method for transmitting pilot configuration information in a relay system, comprising: generating, by a base station, high layer signaling carrying pilot configuration information configured for a Relay-Physical Downlink Control Channel, R-PDCCH, wherein the pilot configuration information comprises at least one of pilot type information and pilot port information, and wherein the pilot type information comprises common pilot type information or dedicated pilot type information, wherein the pilot port information comprises at least one of pilot port number information and information of the number of pilot ports configured for the R-PDCCH, and when the high layer signaling carries pilot port number information and information of the number of pilot ports, the pilot port number information is the starting pilot port number of the pilot ports configured for the R-PDCCH; and transmitting, by the base station, the high layer signaling to a relay node, wherein when the base station is required to configure R-PDCCHs in a plurality of physical resource blocks with a pilot, the high layer signaling further carries indicator information of the plurality of physical resource blocks, and wherein in the high layer signaling, the indicator information of the plurality of physical resource blocks corresponds to different pilot configuration information.
