Abstract:
Methods and apparatuses determine and indicate QCL behavior for or to a UE. A method for determining QCL behavior for the UE method includes, when configured in TM10 for a serving cell, determining whether a CRC for a PDSCH transmission scheduled by DCI format 1A is scrambled using a C-RNTI. The method also includes, in response to determining C-RNTI scrambling, determining whether a transmission scheme of the PDSCH transmission uses a non-MBSFN subframe configuration and whether the PDSCH transmission is transmitted on antenna port 0 or a TxD scheme is used. The method further includes, in response to determining the non-MBSFN subframe configuration and antenna port 0 or the TxD scheme being used, determining to use QCL behavior 1 for PDSCH reception. Additionally, the method includes, in response to determining a MBSFN subframe configuration and antenna port 7 being used, determining to use QCL behavior 2 for PDSCH reception.
