<p>Embodiments of the present invention provide a control channel resource mapping method, apparatus and system, relate to the communications field and can solve the problem of mismatching between the length of control channel coded and rate matched output data and the data length that can be contained in a control channel physical subunit in a case where the data length that can be placed in the mapped control channel physical subunit is unknown. The method comprises: determining a reference value of the number of REs of the control channel physical subunit; determining the length of ePDCCH coded and rate matched data, mapping the ePDCCH coded and rate matched data as a symbol sequence; according to the ePDCCH, selecting a certain number of symbols from the symbol sequence to perform symbol repetition or symbol puncture on the total actual number of the REs of the to-be-mapped control channel physical subunit and the length of the ePDCCH coded and rate matched data to form a new symbol sequence; and mapping the new symbol sequence to a corresponding control channel physical subunit. The embodiments of the present invention are applied to channel resource mapping.</p> |
