Claim:
1. A method for processing downlink control information, comprising: transmitting in a subframe n downlink control information for the subframe n, or transmitting in a subframe n−1 the downlink control information for the subframe n, wherein n is an integer which is greater than or equal to 0, n and n−1 represent subframe numbers, and the subframe n−1 is a previous subframe immediately adjacent to the subframe n, and when n is equal to 0, the subframe n is a first subframe of a current frame, and the subframe n−1 is the last subframe of a previous frame immediately adjacent to the current frame, and wherein when the downlink control information for the subframe n is transmitted in the subframe n, the downlink control information for the subframe n is transmitted in a first time slot and a second time slot of the subframe n, wherein a time-domain position of a region where the downlink control information is transmitted in the second time slot of the subframe n is m consecutive OFDM symbols starting from a h-th OFDM symbol in the second time slot of the subframe n, where h and m are predefined values or h and m are configured by signalling, and m is an integer which is greater than or equal to 1, and h is an integer which is greater than or equal to 1, or the time-domain position of the region where the downlink control information is transmitted in the second time slot of the subframe n is from a first OFDM symbol to a last OFDM symbol in the second time slot of the subframe n; and there is one or two regions where the downlink control information is transmitted in the first time slot of the subframe n, and wherein when there is one region where the downlink control information is transmitted in the first time slot of the subframe n, the time-domain position of the region is first A consecutive OFDM symbols in the first time slot of the subframe n, where A is configured by the signalling, which is transmitted on a Physical Control Format Indicator Channel (PCFICH), and A is an integer which is greater than or equal to 1, or the time-domain position of the region is last B consecutive OFDM symbols in the first time slot of the subframe n, where B is configured by the signalling or is a predefined value, and B is an integer which is greater than or equal to 1; and when there are two regions where the downlink control information is transmitted in the first time slot of the subframe n, a time-domain position of the first region is the first A consecutive OFDM symbols in the first time slot of the subframe n, where A is configured by the signalling, which is transmitted on the PCFICH, and A is an integer which is greater than or equal to 1, a time-domain position of the second region is the last B consecutive OFDM symbols in the first time slot of the subframe n, where B is configured by the signalling, or B is a predefined value or B is determined by A, and B and is an integer which is greater than or equal to 1, and a frequency-domain position of the first region is a full bandwidth or a partly consecutive bandwidth, and a frequency-domain position of the second region is configured by the signalling.
