CSI-RS transmission method and detection method and apparatuses thereof

摘要

Disclosed in embodiments of the present invention are a CSI-RS transmission method, an inspection method and a device thereof. The transmission method comprises: transmitting a CSI-RS via any downlink subframe other than a special subframe, a downlink subframe transmitting a control message, or a downlink subframe transmitting a system message. Embodiments of the present invention enable the CSI-RS to be prevented from conflicting with the control message, the system message, and a message carried by the special subframe.

1. A Channel State Information-Reference Signal, CSI-RS, transmission method, comprising:
transmitting CSI-RS in at least one downlink subframe, wherein the at least one downlink subframe excludes special subframes, downlink subframes for transmitting control information, and downlink subframes for transmitting system information; wherein the downlink subframes for transmitting control information comprise a downlink subframe for transmitting synchronization sequence, a downlink subframe configured to Physical Broadcast Channel, PBCH, and a downlink subframe configured to paging channel, PCH; and the downlink subframes for transmitting system information comprise a downlink subframe for transmitting System Information Block, SIB-1; wherein transmitting the CSI-RS in the at least one downlink subframe comprises: transmitting the CSI-RS in at least one of subframe 4 and subframe 9 in the case of uplink-downlink configurations 1; transmitting the CSI-RS in at least one of subframe 3, subframe 4, subframe 8 and subframe 9 in the case of uplink-downlink configuration 2; transmitting the CSI-RS in at least one of subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 3 and subframe 6 configured to the PCH; transmitting the CSI-RS in at least one of subframe 6, subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 3 and subframe 6 not configured to the PCH; transmitting the CSI-RS in at least one of subframe 4, subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 4 and subframe 6 configured to the PCH; transmitting the CSI-RS in at least one of subframe 4, subframe 6, subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 4 and subframe 6 not configured to the PCH; transmitting the CSI-RS in at least one of subframe 3, subframe 4, subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 5 and subframe 6 configured to the PCH; transmitting the CSI-RS in at least one of subframe 3, subframe 4, subframe 6, subframe 7, subframe 8 and subframe 9 in the case of uplink-downlink configuration 5 and subframe 6 not configured to the PCH; and transmitting the CSI-RS in subframe 9 in the case of uplink-downlink configuration 6.
