The embodiments herein provide a method and system to trigger UE handover in a radio communication network including a serving base station and a plurality of candidate base stations. The serving base station shares uplink transmission information associated with the UE with the candidate base stations. A candidate base station detects the presence of the UE located in radio coverage of the candidate base station by obtaining information from the uplink transmission of the UE. Further, the candidate base station computes a second parameter and sends to the serving base station. The serving base station determines to trigger handover procedure when the second parameter meets handover criteria. Further, the serving base station sends handover command to the UE after determining that the second parameter meets handover criteria.

Method and system to trigger UE handover in a radio communication network

Cognitive interference management in Cellular wireless network with relays and micro/pico/femto cells operated in distributed scheduling mode. A cellular system may use RS to improve capacity or for coverage extension. ARS relays the signals between BSand MS by using wireless links between BS-RS and RS-MS during both downlink and uplink transmissions. Embodiments herein disclose a mechanism to explicitly indicate to the MS whether the MAC management messages sent by the BS to the MS are to inform it to perform scanning for interference measurement. Also, disclosed herein is a mechanism to explicitly indicate to the BS whether the message sent by the MS is related to interference measurement.

The embodiments herein disclose an indoor personal relay which has a wireless interface with the BS, which is effective in both cost and technology terms. The indoor personal relay, as disclosed herein is an estimate and forward relay. The relayas disclosed herein does not perform any additional channel decoding/encoding on the data that it receives from the UE or BS. Embodiments disclosed herein enable the relevant UEs to have a high SINR link with the relay. This, in turn, translates to a better effective link quality between the UE and BS and higher indoor rates, which otherwise may have been not as good as a consequence of poor direct link between the UE and the BS. This relay is effectively transparent to the UE. The deployment of relays also implies minimal impact on UE IOT.
