Abstract

Methods, a first, and a second network node as well as a user equipment for exchange of measurement period related parameters are provided. The user equipment (140) performs a method for measuring at least one measurement quantity on a second cell on a second carrier operated by a second radio network node (120). The user equipment (140) receives (203), from the second radio network node (120), an indication indicative of the second carrier and a first parameter to be used by the user equipment for measuring said at least one measurement quantity. The first parameter relates to at least a first measurement period. The user equipment (140) determines (205) the first measurement period based on the first parameter. Moreover, the user equipment (140) measures (207) said at least one measurement quantity on at least the second cell on the second carrier over the first measurement period. The second network node (120) performs a method for providing the first parameter to be used by the user equipment (140). The second network node (120) sends (203), to the user equipment (140), the first parameter and the indication indicative of the second carrier. The first parameter is determined based on a specific length of the first measurement period.
