Exchange of parameters relating to measurement periods

A method in a user equipment for measuring at least one measurement quantity on a second cell on a second carrier operated by a second radio network node, the user equipment being served by at least the second cell on the second carrier and a first cell on a first carrier, the method comprising:

• receiving, from the second radio network node, 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, wherein the first parameter relates to at least a first measurement period;
• determining the first measurement period based on the first parameter;
• and
• measuring said at least one measurement quantity on the second cell on the second carrier over the first measurement period
• wherein the first parameter relates to the first measurement period as T1=μ×Ω1, where T1, μ and Ω1 are the first measurement period, a pre-defined value depending on said at least one measurement quantity, and the first parameter, respectively.

A user equipment for measuring at least one measurement quantity on a second cell on a second carrier operated by a second radio network node, the user equipment being configured to be served by at least the second cell on the second carrier and a first cell on a first carrier, the user equipment comprising:

• a receiver configured to receive, from the second radio network node, 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, wherein the first parameter relates to at least a first measurement period;
• and
• a processing circuit configured to determine the first measurement period based on the first parameter and to measure said at least one measurement quantity on at least the second cell on the second carrier over the first measurement period,
• wherein the first parameter relates to the first measurement period as T1=μ×Ω1, where T1, μ and Ω1 are the first measurement period, a pre-defined value depending on said at least one measurement quantity, and the first parameter, respectively.
