Claim Text:
1. A method comprising: receiving, by a user equipment (UE) in a cluster, a joint transmission comprising a plurality of resource blocks (RBs) from multiple respective base stations (eNBs) in the cluster, each RB comprising a plurality of physical downlink shared channel (PDSCH) resource elements (REs), wherein: extracting, by the UE, a linear combination of the multiple symbols from the joint transmission; detecting, by the UE, the first CRS from the first RB, wherein the UE employs the first CRS to estimate a first channel response of a first channel disposed between the UE and the first eNB; detecting, by the UE, the second CRS from the second RB, wherein the UE employs the second CRS to estimate a second channel response of a second channel disposed between the UE and the second eNB; and detecting, by the UE, a third CRS from a third RB, wherein the UE employs the third CRS to estimate a third channel response of a third channel disposed between the UE and a third eNB; multiplying, by the UE, the first channel response by the first CRS, resulting in a first reconstructed CRS; multiplying, by the UE, the second channel response by the second CRS, resulting in a second reconstructed CRS; and multiplying, by the UE, the third channel response by the third CRS, resulting in the third reconstructed CRS.
