The present invention provides an uplink data receiving method and apparatus of wireless transceiver device. The method includes: obtaining a wireless channel state parameter of neighboring wireless transceiver device of the device; obtaining downlink data sent by the neighboring wireless transceiver device in a cross slot with the device; reestablishing an interference signal according to the wireless channel state parameter and the downlink data; and removing the interference signal from an uplink data signal received by the device. By reestablishing the interference signal of the neighboring wireless transceiver device on an uplink data signal received by the device in the cross slot, and removing the interference signal from the uplink data signal received by the device, cross slot interference may be eliminated without influencing the flexible allocation of a dynamic TDD system on wireless resources.
