Claim Text:
1. A method for determining a transmission subframe for data transmission between a first user equipment and a second user equipment, wherein the first user equipment and the second user equipment directly communicate with each other and with a base station, the method comprising: determining a first transmission subframe set and a second transmission subframe set of the first user equipment within a predetermined time range, wherein the first transmission subframe set is a set of a subframe which the first user equipment transmits uplink information to the base station, the second transmission subframe set is a set of a subframe on which the first user equipment directly transmits data the second user equipment, wherein the second transmission subframe set does not overlap in time with a subframe in which the second user equipment transmits uplink information to the base station or with a subframe in which the second user equipment directly on transmits data to the first user equipment; and providing information of the second transmission subframe set of the first user equipment to the first user equipment; wherein the uplink information comprises uplink data information and uplink response feedback information; wherein the first transmission subframe set of the first user equipment comprises a first subset of a subframe on which the first user equipment transmits the uplink data information and a second subset of a subframe on which the first user equipment transmits the uplink response feedback information; and in response to resources of the second subframe subset not being comprised in a union set of the first subframe subset and the second transmission subframe set of the first user equipment, the method further comprises re-determining a subframe for the first user equipment to transmit downlink data, so that the second subset of the subframe on which the first user equipment transmits uplink response feedback information corresponding to the downlink data is comprised in the union set of the first subframe subset and the second transmission subframe set of the first user equipment, wherein the second subset and the subframe for the first user equipment to transmit downlink data have a pre-configured relationship.
