A method for signaling configuration of a physical uplink shared channel, the method being used for a LTE/LTE-A system, wherein the method comprises: sending, by a base station, downlink control information to a target user equipment through a physical downlink control channel, wherein the downlink control information comprises indication information combining a cyclic shift and an orthogonal cover code for a demodulation reference signal, and is used for scheduling the physical uplink shared channel in a multi-antenna port transmission and/or a single antenna port transmission; the indication information combining the cyclic shift and the orthogonal cover code for the demodulation reference signal is 3-bit or 4-bit in size, and used for using a combination of orthogonal resources <n DMRS 0, n occ > to indicate both the cyclic shift and the orthogonal cover code for the demodulation reference signal which are sent to the target user equipment from the base station, wherein n DMRS 0 represents that the base station uses the downlink control information to indicate a cyclic shift for a demodulation reference signal of data in a spatially-multiplexed 0 th layer of the target user equipment, or indicate a reference value or an initial value or a basic value of a cyclic shift for a demodulation reference signal of data in each spatially-multiplexed layer, or indicate a cyclic shift for a demodulation reference signal of a user in a single antenna port transmission mode; n occ represents an orthogonal cover code index for the demodulation reference signal of data in the spatially-multiplexed 0 th layer of the target user equipment, or represents an orthogonal cover code index for the demodulation reference signal of the user in the single antenna port transmission mode. sending, by a base station, downlink control information to a target user equipment through a physical downlink control channel, wherein the downlink control information comprises indication information combining a cyclic shift and an orthogonal cover code for a demodulation reference signal, and is used for scheduling the physical uplink shared channel in a multi-antenna port transmission and/or a single antenna port transmission; the indication information combining the cyclic shift and the orthogonal cover code for the demodulation reference signal is 3-bit or 4-bit in size, and used for using a combination of orthogonal resources <n DMRS 0, n occ > to indicate both the cyclic shift and the orthogonal cover code for the demodulation reference signal which are sent to the target user equipment from the base station, wherein n DMRS 0 represents that the base station uses the downlink control information to indicate a cyclic shift for a demodulation reference signal of data in a spatially-multiplexed 0 th layer of the target user equipment, or indicate a reference value or an initial value or a basic value of a cyclic shift for a demodulation reference signal of data in each spatially-multiplexed layer, or indicate a cyclic shift for a demodulation reference signal of a user in a single antenna port transmission mode; n occ represents an orthogonal cover code index for the demodulation reference signal of data in the spatially-multiplexed 0 th layer of the target user equipment, or represents an orthogonal cover code index for the demodulation reference signal of the user in the single antenna port transmission mode.
