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.

The determined antenna port is a DeModulation Reference Signal (DMRS) port to which the UE is assigned. Symbols are mapped in sequence to resource elements (REs) and transmitted via the determined antenna port to the UE.

Abstract: A method and an apparatus for transmitting data in a wireless communication system are provided. A length of a circular buffer associated with rate matching is identified. Rate matching is performed for a code block based on the circular buffer. The data is transmitted based on the rate matching. In case that the rate matching is limited buffer rate matching (LBRM), the length of the circular buffer associated with the LBRM is determined based on a value obtained by dividing a reference transport block size (TBS) by a product of a number of code blocks and a reference code rate for the LBRM.
