Abstract: A system, method and device to overcome the effects of mobility in OFDM wireless cellular networks. Individual beams are isolated and Doppler impairments are compensated so the constituent beams can reach the users in DL with ideally no Doppler impairments. Similarly in UL the signals corresponding to the different spatial beams are detected and their Doppler impairments compensated.

Abstract: A system and method are provided for assisting user devices in performing OFDMA downlink interference cancellation, in which an interfering base station transmits a downlink signal in a first slot and a second slot, both slots including cell reference signals (CRSs) for physical channel estimation, the CRS of the second slot is modified to indicate encoded values of parameters characterizing the physical channel according to an encoding procedure, the slots are received by a served user device that detects the physical channel parameters carried by dedicated control signalling and encodes them by the encoding procedure, an unchanged CRS is reconstructed, and the slots are received by an interfered user device obtaining the encoded values and comparing to parameter patterns indicating absence of modifications in the CRSs, wherein if the encoded values are different from the patterns, the interfered user device decodes them to perform interference cancellation of the downlink signal.

Abstract: A method for performing virtualization of a radio access technology (RAT) over Orthogonal Frequency-Division Multiple Access (OFDMA) wireless networks is provided. The method includes splitting OFDMA time-frequency resources into non-overlapping regions including a virtualization region including a part of a spectrum and the OFDMA symbols that are reserved for virtualization of the RAT; reserving resource elements of the OFDMA time-frequency resources in the virtualization region, for insertion of downlink reference signals including complex sequences known by a receiver to perform downlink channel estimation with a specified separation between signals in time and frequency domains; inserting training or pilot signals along the OFDMA time-frequency resources of the virtualization region; and mapping complex baseband symbols corresponding to information from the RAT into the OFDMA time-frequency resources of the virtualization region.
