Celebi does not explicitly disclose determining that the CSI-RS is a tracking reference signal.
However, Park teaches determining that the CSI-RS is a tracking reference signal [paragraphs 0287, 0467, determining that the CSI-RS is a tracking reference signa (a CSI-RS through the specific serving beam may be used for the purpose of an RS (e.g., tracking RS (TRS)))].
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to improve upon the method described in Celebi by determining that the CSI-RS is a tracking reference signal as taught by Park because it would provide the Celebi’s method with the enhanced capability of improving a reception performance of a reference signal [Park, paragraphs 0004, 0025].

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to improve upon the method described in Celebi by including a bitmap identifying resources as taught by Park because it would provide the Celebi’s method with the enhanced capability of improving a reception performance of a reference signal [Park, paragraphs 0004, 0025].
As per claim 12, Celebi discloses the method of claim 11, Celebi does not explicitly disclose wherein each bit of the bitmap corresponds to a resource block group of the single CSI reference resource and identifies whether the CSI-RS is received on the corresponding resource block group.
However, Park teaches wherein each bit of the bitmap corresponds to a resource block group of the single CSI reference resource and identifies whether the CSI-RS is received on the corresponding resource block group [paragraphs 0083, 0192, 0222-0224, 0269, 0283, 0285, 0364, 0365, 0372, 0374, 0414, 0425, 0547, wherein each bit of the bitmap corresponds to a resource block group of the single CSI reference resource and identifies whether the CSI-RS is received on the corresponding resource block group (time instances with respect to specific CSI-RS; CSI-RS resource is mapped; number of available bits of a PDCCH; an RB group (e.g., RBG))].
