Abstract: Methods and Apparatus for processing data encoded by low density parity check (LDPC) in a communication system are disclosed herein. In one embodiment, a method performed by a first node is disclosed. The method comprises: encoding an information bit sequence based on an LDPC coding scheme to obtain an encoded bit sequence; generating a master bit sequence based on the encoded bit sequence; selecting a subset of the master bit sequence according to a rate matching rule to obtain a rate matched bit sequence; interleaving the rate matched bit sequence according to a predetermined index sequence to obtain a to-be-transmitted bit sequence; and transmitting the to-be-transmitted bit sequence to a second node.

Abstract: Disclosed are a method, apparatus and system for data transmission in a downlink virtual multi-antenna system. The method includes: N terminals receive downlink data and/or downlink Demodulation Reference Signals (DMRSs) from one Node B or multiple Nodes B, N being a positive integer larger than or equal to 2; and one terminal in the N terminals forwards the downlink data and/or downlink DMRSs received from the one Node B or multiple Nodes B to M terminal(s), M being a positive integer larger than or equal to 1. A first forwarding unit of the apparatus is configured to forward received downlink data and/or downlink DMRSs of a Node B to M terminal(s) by one terminal in N terminals, M being a positive integer larger than or equal to 1.
