Abstract
According to some embodiments, a network node is operable to separately schedule radio transmissions per sub-subframe (SSF). A method in the network node comprises mapping a first demodulation reference signal (DMRS) to first resource elements in a first SSF. The first resource elements are associated with a first set of antenna ports. The method includes mapping a second DMRS to second resource elements in a second SSF. The second resource elements are associated with the first set of one or more antenna ports and precoding of the second DMRS differs from a precoding of the first DMRS. The method further includes scheduling a radio transmission during the first SSF precoded in accordance with the first DMRS, and scheduling a radio transmission during the second SSF precoded in accordance with the second DMRS. In particular embodiments, a subframe may comprise two, four, or eight sub-subframes.
