    摘要: The described techniques relate to improved methods, systems, devices, or apparatuses that support communication schemes for small cyclic delay diversity (SCDD) reference signals. A base station may transmit a control message comprising at least one channel state information (CSI) configuration parameter to a user equipment (UE). The UE may identify a time offset between a plurality of virtual antennas of the base station based at least in part on the CSI configuration parameter. The UE may perform measurements of a plurality of CSI reference signals (CSI-RSs) transmitted by the base station and associated with the virtual antennas. The UE may transmit a feedback message based at least in part on the determined time offset and the measurements of the CSI-RSs.

    摘要: The present invention provides a method and apparatus for indicating downlink channel measurement and a method and apparatus for performing channel measurement. The method for indicating downlink channel measurement comprises: receiving information on interferes of a user equipment; generating, based on downlink subframe configuration information, a downlink channel measurement indication for each of possible combinations of the interferers, wherein the channel measurement indication is adapted to indicate a subframe group to be measured by a user equipment; and sending the downlink channel measurement indication to the user equipment so as to indicate the user equipment to perform corresponding downlink channel measurement. According to embodiments of the present invention, the subframe groups that are required to be measured by the user equipment may be determined with respect to possible combinations of interferers corresponding to different levels of interference. Thus, the user equipment may perform channel measurement for respective subframe groups. Therefore, the channel quality as determined in such way will be more accurate and reliable and better match the actual channel condition. Moreover, it also provides a possibility for the serving node to perform the scheduling more accurately and effectively.
