Original Abstract Submitted
Apparatuses and methods for codebook subset restriction for coherent joint transmission in wireless networks. A method includes receiving information about a channel state information (CSI) report associated with N>1 groups of antenna ports. The information indicates (i) a coherent joint transmission (CJT) codebook, (ii) a rank restriction, and (iii) Ncodebook subset restrictions (CBSRs). The method further includes identifying, based on the rank restriction, a set Sof one or more rank values allowed for the CSI report; identifying, based on the NCBSRs, sets S, . . . , S; determining the CSI report associated with the Ngroups of antenna ports based on the CJT codebook, the set S, and the sets S, . . . , S; and transmitting the CSI report. For n=1, . . . , N, the set Sis associated with n-th groups of antenna ports of the Ngroups of antenna ports. The set Sincludes spatial-domain (SD) basis vectors that are allowed for the CSI report.
