Abstract: 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.

Abstract: Precoding for multiple transmission streams in multiple antenna systems. Disclosed herein is a general method that transmits signal from multiple antennas using a one/two dimensional precoder. This precoder is fixed in a given resource block (RB) or slot, which is composed of P subcarriers and Q OFDM symbols (where the values for P and Q are greater than or equal to 1). The precoder in each resource block may take same or different values, which span the two dimensional time-frequency grid. The precoder is chosen as a function of either logical frequency index or physical frequency index of the RB.

Abstract: Methods of waveform switching in a cellular network are described. The method includes configuring, by a User Equipment, a first waveform for a Physical Uplink Shared Channel (PUSCH) transmission. A Base Station selects a second waveform for dynamically switching from the first waveform. The second waveform is used for communication in the scheduled PUSCH transmission based on waveform switching parameters. The Base Station transmits control information defined by the waveform switching parameters, to the User Equipment.
