<p>In LTE-A release 11 for measuring coordinated multi-point CoMP resources a CoMP resource management set CRMS and a CoMP measurement set CMS is defined (3GPP TR 36.819). The measurement is based on reference signal receiving power RSRP measurement of channel state information - reference signal CSI- RS resource. The measurement set used in a mobile station may be changed by a command (MAC-CE signalling element) from the base station. Problem: There might be situation where after the change the mobile terminal measures CSI-RS resources which are inactive (SCell). This would lead to a waste of energy in the UE. Solution: The UE stops measuring after the change (adding) and continues only after being commanded to by the base station.</p> |
