Abstract

A measurement pattern for at least one automatic gain control tracking loop in a user equipment device is determined, when resource restrictions have been applied to the user equipment device, the resource restrictions comprising at least one measurement restriction pattern. Then automatic gain control measurements are performed by the user equipment device according to the measurement patterns of the at least one automatic gain control tracking loop. AGC measurements are thus in effect gated according restriction patterns (tables 1 - 5). Fig.2 illustrates the general principle of performing AGC tracking per sub-frame set, with measurements and their application separated in time (arrows). Measurements may be taken during muted subframes, e.g. almost blank subframes (ABS). Keywords: Long Term Evolution (LTE) networks, 4G, enhanced inter-cell co-ordination functionality, eICIC, E-UTRAN, macro cell, pico cell, femto cell, radio resource management, RRM. .
