Abstract
Official abstract text for this publication.
A radio network node ( 28 ) comprises a transmitter/receiver ( 48, 82, 93 ) configured to communicate over an air interface ( 32 ) with a wireless terminal ( 30 ); a scheduler ( 46, 84 ); and a order signal determination means ( 46, 62, 84 ). The scheduler ( 46, 84 ) schedules pilot signals, including common pilot signals transmitted for channel estimation, for transmission over the air interface to the wireless terminal. The order signal determination means ( 46, 62, 84 ) is configured to make a selective determination whether additional pilot signals for data demodulation are also to be transmitted to the wireless terminal ( 30 ) in addition to the common pilot signals transmitted for the channel estimation. The wireless terminal ( 30 ) comprises a transmitter and receiver ( 50, 101, 112 ) and pilot selection means ( 68 ). The pilot selection means ( 68 ) is configured to make a determination regarding which pilot signals transmitted by the radio network node are to be utilized by the wireless terminal. The pilot signals transmitted by the radio network node include common pilot signals transmitted for channel estimation and additional pilot signals transmitted for data demodulation.
