Abstract
A method includes determining one of a multiplicity of subframes in a resource space in which a shortened subframe is to be communicated. Each of the subframes has a predetermined number of symbol positions. The resource space includes the multiplicity of subframes. The method includes communicating the shortened subframe in the determined subframe. The shortened subframe has a multiplicity of active symbols at first symbol positions in the determined subframe and has a multiplicity of blanked symbols at second symbol positions in the determined subframe. In an embodiment, each of the subframes is a first subframe carried on subcarrier. The resource space corresponds to a special subframe in a frame including the special subframe and a multiplicity of second subframes. The special subframe and the plurality of second subframes are located in different timeslots. Apparatus, computer programs, and program products are also disclosed.
