Abstract: Systems and methods of performing data transmission and reception in a communication system are presented. In one exemplary embodiment, a method performed by a wireless device for transmitting a signal in a first communication system that is frequency-domain multiplexed with a second communication system may include generating (201), by a modulator (401), a modulated signal that represents one or more information symbols. The modulated signal may include one or more modulation symbols of the first communication system. The method may also include filtering (203), by a pulse shaping filter (403), the modulated signal to obtain the filtered modulated signal. The pulse shaping filter (403) may be configured to operate with a period that corresponds to the symbol rate of the second communication system. In addition, the method may include transmitting (209), by a transmitter (409), the filtered modulated signal at a carrier or sub-carrier frequency of the first communication system.

Abstract: The technology involves data processing during intra-site handover procedures. At least two directional antennas of a base station receive data carrying signals originating from a mobile units positioned in an intra-site handover area defined by the overlapping radio coverage of the antennas. The directional antennas performs an initial data signal detection of the received data signals resulting in detected data, which typically results in a loss of radio performance of the antenna. The detected data from the directional antennas is then processed to generate processed data. The performance loss is compensated by providing differential antenna gain of the directional antennas within the handover area.
