User equipment transmits a current value of state information to a radio access node if the radio access node does not hold the current value

摘要

A radio access network 100 includes a radio access node 103, 104, for example an evolved Node B (eNB), associated with a cell 105, 106 and user equipment 102. State information is maintained at the user equipment 102, the state information comprising state information part, for example In Device Coexistence (IDC) interference, associable with different values. A current value associated with the state information part is transmitted from the user equipment 102 to the radio access node 103, 104 in response to detecting a predetermined trigger indicating that the radio access node 103, 104 may not hold the current value. The radio access node 103, 104 is relied on to hold the current value associated with the state information part if no predetermined trigger is detected.
