PUCCH resource allocation for E-PDCCH in communications system

摘要

An exemplary embodiment discloses a multi-subframe physical uplink control channel PUCCH resource arrangement for PUCCH format 1 a/1 b resource allocation for en¬ hanced physical downlink control channel EPDCCH in time division duplex TDD transmission. A definition of a semi-static offset for each EPDCCH set is extended by considering multiple downlink subframes, and a dynamic offset mechanism is en- hanced to avoid resource collision between multiple DL subframes.
