Title: METHODS AND APPARATUSES FOR CONTROLLING MEASUREMENT BANDWIDTH TO ACCOUNT FOR IMPAIRMENTS
Abstract:
There are provided methods, apparatuses, and computer programs for improving measurement of a reference signal parameter measured by a wireless device (800), the reference signal parameter being a parameter of a reference signal transmitted by a radio network node (900) in a wireless communication network (700). An example method (300) includes determining (S305) that the wireless device is operating with a low measurement accuracy condition that affects measurement of the reference signal parameter. A severity of the low measurement accuracy condition has a positive correlation with the quality of a channel over which the reference signal is received. The method further includes adapting (S310) a first measurement bandwidth in response to determining that the wireless device has the low measurement accuracy condition that is positively correlated with the quality of the channel. The method further includes measuring (S320) a first reference signal parameter using the adapted first measurement bandwidth.
