LTE: Why E-UTRA has provision to configure only measObject with a single frequency ?

Question

I have gone through spec 36.331.
"E-UTRAN only configures a single measurement object for a given frequency, i.e. it is not possible to configure two or more measurement objects for the same frequency with different associated parameters, e.g. different offsets and/ or blacklists".

why such limitations have been there ?

Answer 1

When the UE is in RRC connected mode. E-NodeB (or RRC) has to sent a set of cells for which UE has to report. The reason is UE maintains a single measurement object list, a single reporting configuration list and a single measurement identities list. It has parameter only to configure one parameter and do the measurements for that and the reason for that is:

• to ensure that, whenever the UE has a measConfig, it includes a measObject for the serving frequency;
• to configure at most one measurement identity using a reporting configuration with the purpose set to
  'reportCGI';
