Disclosed are methods, wireless network nodes and terminal devices for matching an uplink coverage area and a downlink coverage area. The method may include determine an uplink coverage margin and a downlink coverage margin, calculate an uplink-downlink coverage gap based on differences of the uplink coverage margins and the downlink coverage margins, determine whether the uplink coverage area and the downlink coverage area are matched with each other, and adjust at least one of the uplink coverage area and the downlink coverage area in response to a mismatch of the uplink coverage area and the downlink coverage area. With the proposed methods, wireless network nodes and terminal devices, the uplink and downlink coverage areas could be matched, thereby diminishing the communication overhead and decreasing the delay.
