Transmission scheme and quasi co-location assumption of antenna ports for PDSCH of transmission mode 10 for LTE advanced

摘要

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.

1. A method for determining quasi co-location (QCL) behavior for a user equipment (UE), the method comprising:
when configured in transmission mode 10 (TM10) for a serving cell in long term evolution (LTE) wireless communication system, determining, by the UE, whether a cyclical redundancy check (CRC) for a physical downlink shared channel (PDSCH) transmission is scrambled using a cell radio network temporary identifier (C-RNTI); in response to determining that the CRC for the PDSCH transmission is scrambled using the C-RNTI, determining whether a transmission scheme of the PDSCH transmission uses a non-multicast broadcast single frequency network (non-MB SFN) subframe configuration and whether the PDSCH transmission is transmitted on antenna port 0 or a transmit diversity scheme is used; and in response to determining the non-MBSFN subframe configuration and antenna port 0 or the transmit diversity scheme being used, determining to use QCL behavior 1 for PDSCH reception.
