Abstract
A data alignment method capable of preventing degradation in demodulation performance due to variation in signal qualities when a data signal to which a Turbo code is applied is transmitted simultaneously from a plurality of cells. The method divides signal components to be used for data alignment into resources common to all the cells and resources dependent on the cells and transmits encoded and rate-matched data with the first half thereof aligned to the resources common to all the cells and the second half thereof aligned to the resources dependent on the cells.
Claims16
A communication apparatus for communicating with a plurality of cells that perform a coordinated multipoint communication, the communication apparatus comprising:
- a receiving section configured to receive control information related a mapping of a physical downlink shared channel (PDSCH);
- and
- a determining section configured to determine the mapping of the PDSCH based on the control information,
- wherein the plurality of cells include a first cell and a second cell, and the PDSCH is mapped on a resource in accordance with a number of antenna ports for a cell-specific reference signal and a MBMS single frequency network (MBSFN) sub-frame configuration, a first portion of the PDSCH being mapped on a first resource, on which a control signal or a cell-specific reference signal is not mapped in the first cell and the second cell, and a second portion of the PDSCH being mapped on a second resource, on which a control signal or a cell-specific reference signal is allowed to be mapped in at least one of the first cell and the second cell.
