SYMMETRIC PUNCTURING FOR CQI/PCI REPORTING ON THE HS-DPCCH

摘要

Methods and apparatus for encoding control information with subsequent puncturing are disclosed. Control information generated by a user equipment (UE) is provided, where the control information comprises a first bit sequence, a second bit sequence, and a third bit sequence (1804). The method comprises: arranging said bit sequences to produce a bit sequence XI (1806); padding the bit sequence XI with a bit sequence P to produce a bit sequence XI' (1808); convolution encoding the bit sequence XI' to produce an encoded bit sequence Zl (1810); and puncturing the bit sequence Zl using a predefined puncturing pattern to produce a bit sequence Rl (1812), wherein the predefined puncturing pattern is a rotationally symmetric puncturing pattern (700,900). The control information may comprise CQI/PCI reports, which may be transmitted on a HS-DPCCH.
