Abstract
A wireless device () receives a downlink reference signal () from a radio network node () over a downlink channel (), and determines channel information () based on measurement of the downlink reference signal (). The wireless device () then transmits, to the radio network node () over an uplink channel (), an uplink signal () that implicitly conveys the determined channel information (). The radio network node () jointly (i) identifies which candidate uplink signal in a set () of candidate uplink signals (--N) is received; and (ii) determines an estimate () of the uplink channel () from the received uplink signal (). The radio network node () determines the channel information () implicitly conveyed by the identified candidate uplink signal, and then determines an estimate () of the downlink channel () based on the determined channel information () and the determined estimate () of the uplink channel ().
