A modified subframe structure is defined for a subset of a plurality of subframes. The modified subframe structure includes a first portion with one or more blank symbols over which a network node can measure monitor to determine whether the subframe is used as a downlink (or uplink) subframe by a neighboring network node. The modified subframe structure can also include a second portion of symbols for communicating control information or data in the subframe, which can be based on determining whether the subframe is used as a downlink (or uplink) subframe by the neighboring network node. This can lessen the impact of possible interference caused by the network nodes dynamically switching time division duplexing (TDD) subframe configurations by enabling network nodes to determine when a neighboring node is transmitting in a subframe, and accordingly avoiding transmitting in the subframe.
