Abstract:
A network access node eNB sends to a user equipment UE a pattern of subframe measurement restrictions and an indication of how to utilize the pattern for measuring subframes. The indication may select from among: the UE's own-cell measurements; the UE's neighbor-cell measurements; both same and neighbor-cell measurements, and no measurement restrictions. The eNB may generate the pattern from an almost-blank subframe ABS pattern for the UE's own-cell and of its neighbor-cell. The pattern and indication may be sent in separate RRC messages, or if sent in one message there is a second indication sent in a second RRC message instructing the UE to terminate utilizing the pattern and indication for restricting its subframe measurements. Embodiments are particularly useful for inter-cell interference mitigation eICIC for the LTE-Advanced system.
