3. The apparatus of claim 2 , wherein the system information block comprises system information block 5 and wherein the measurement configuration comprises an indication indicative of whether or not relaxed performance measurement is to be applied to the at least one carrier in excess of three carriers.

4. The apparatus of claim 1 , wherein the user equipment is in a connected radio resource control mode and the measurement configuration is transmitted via a signaling in response to receiving a capability indication regarding monitoring from the user equipment.

5. A method comprising:

receiving, at a user equipment in an idle mode, a measurement configuration sent via a system information block, wherein the measurement configuration for at least one low priority carrier in excess of three carriers, wherein at least one of the three carriers is a high priority carrier; and

handling, by the user equipment, one or more low priority measurements of the at least one low priority carrier in excess of three carriers with relaxed performance requirements, wherein the relaxed performance requirements applied to the at least one low priority carrier allow more time for the user requirement to identify a new cell on the at least one low priority carrier than a corresponding requirement for the high priority carrier.

6. The method of claim 5 , wherein the measurement configuration is received via at least one of a broadcast or signaling from a base station.

7. The method of claim 5 , wherein the system information block comprises system information block 5 and wherein the measurement configuration comprises an indication indicative of whether or not relaxed performance measurement is to be applied to the at least one carrier in excess of three carriers.

8. The method of claim 5 , wherein the handling comprises performing measurements of the at least one carrier in excess of three carriers using best efforts to scan or measure the at least one carrier.

9. The method of claim 5 , wherein the handling comprises performing measurements of the at least one carrier by at least one of using best efforts to measure the at least one carrier, ignoring the at least one carrier, scanning, or measuring the at least one carrier.

10. A method comprising:

receiving, at a user equipment in a connected radio resource control mode, a measurement configuration sent in response to providing a network a capability indication regarding monitoring at least one low priority carrier in excess of three carriers, wherein at least one of the three carriers is a high priority carrier; and

performing, by the user equipment, monitoring of the at least one low priority carrier in excess of three carriers, wherein the at least one low priority carrier in excess of three carriers is monitored at a lower priority and with relaxed performance requirements when compared to the three high priority carriers,

wherein the relaxed performance requirements applied to the at least one low priority carrier allow more time for the user equipment to identify a new cell on the at least one low priority carrier than a corresponding requirement for the high priority carrier.

11. The method of claim 10 , wherein the capability information indicates whether the user equipment supports carrier measurements in excess of three carriers.

12. The method of claim 10 , wherein the measurement configuration is received via at least one of a broadcast or signaling from a base station.

13. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform at least the following:

receive, at the apparatus in an idle mode, a measurement configuration sent via a system information block, wherein the measurement configuration for at least one low priority carrier in excess of three carriers, wherein at least one of the three carriers is a high priority carrier; and

handle, by the apparatus, one or more low priority measurements of the at least one low priority carrier in excess of three carriers with relaxed performance requirements, wherein the relaxed performance requirements applied to the at least one low priority carrier allow more time for the apparatus to identify a new cell on the at least one low priority carrier than a corresponding requirement for the high priority carrier.

14. The apparatus of claim 13 , wherein the measurement configuration is received via at least one of a broadcast or signaling from a base station.

15. The apparatus of claim 13 , wherein the system information block comprises system information block 5 and wherein the measurement configuration comprises an indication indicative of whether or not relaxed performance measurement is to be applied to the at least one carrier in excess of three carriers.

16. The apparatus of claim 13 , wherein the handling comprises performing measurements of the at least one carrier in excess of three carriers using best efforts to scan or measure the at least one carrier.

17. The apparatus of claim 13 , wherein the handling comprises performing measurements of the at least one carrier by at least one of using best efforts to measure the at least one carrier, ignoring the at least one carrier, scanning, or measuring the at least one carrier.

18. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform at least the following

receive, at the apparatus in a connected radio resource control mode, a measurement configuration sent in response to providing a network a capability indication regarding monitoring at least one low priority carrier in excess of three carriers, wherein at least one of the three carriers is a high priority carrier; and

perform, by the apparatus, monitoring of the at least one low priority carrier in excess of three carriers, wherein the at least one low priority carrier in excess of three carriers is monitored at a lower priority and with relaxed performance requirements when compared to the three high priority carriers,

wherein the relaxed performance requirements applied to the at least one low priority carrier allow more time for the apparatus to identify a new cell on the at least one low priority carrier than a corresponding requirement for the high priority carrier.
