Patent number: 10616890Abstract: Methods and apparatuses for controlling at least one device configured to receive scheduled frequency resources of a scheduled system are disclosed. At least one device in inactive mode is allocated a secondary frequency resource independently from scheduling of the scheduled system. A signal is transmitted to the at least one device in inactive mode a signal on the secondary frequency resource to control reception of the scheduled frequency resources.

Patent number: 10498557Abstract: A signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM) is received over a channel. The signal is down-sampled into a first sequence including N samples, N corresponding to the number of used subcarriers. The first Nh samples and the last Nt samples are removed from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt. The second sequence is correlated with a reference sequence which has a length N-Nh-Nt, and a frequency response of the channel is estimated over the N used subcarriers based on a result of the correlation.Type: GrantFiled: July 20, 2016Date of Patent: December 3, 2019Assignee: Nokia Solutions and Networks OyInventors: Gilberto Berardinelli, Frank Frederiksen, Klaus Ingemann Pedersen, Kari Pekka Pajukoski

Publication number: 20180375708Abstract: Methods and apparatuses for Orthogonal Frequency Division Multiplexing (OFDM) based communication are disclosed. In a method at least some least important bits derived from data to be transmitted are mapped into at least one portion of an OFDM transmission unit, the at least one portion being reserved for the least important bits. More important bits derived from said data are mapped into a different portion of the ODFM transmission unit.Type: ApplicationFiled: July 13, 2015Publication date: December 27, 2018Inventors: Gilberto BERARDINELLI, Frank FREDERIKSEN, Klaus Ingemann PEDERSEN, Preben Elgaard MOGENSEN

Publication number: 20170214559Abstract: A method is disclosed for signal processing in a radio system. The method comprises generating (801), in an apparatus (602), a single carrier frequency division multiplexing SC-FDM signal having a shorter duration than a time symbol duration defined by a radio standard applied in the radio system. The signal is transmitted (802) from the communications apparatus (602). The method comprises receiving (803) said signal from the communications apparatus (602), wherein orthogonality of frequency subcarriers is maintained at a receiver (601) of the signal.Type: ApplicationFiled: January 29, 2014Publication date: July 27, 2017Inventors: Gilberto BERARDINELLI, Fernando TAVARES, Frank FREDERIKSEN

Patent number: 9544171Abstract: An apparatus (UEA) may generate a zero-tail signal to be transmitted in an LTE/LTE-A cell, by introducing time domain samples with zero power or very low power in specific positions of a time symbol tail. The apparatus (UEA) may transmit the generated zero-tail signal to a base station (eNB), such that a first user terminal (UEA) is located in the cell farther away (e.g. on a cell edge) from the base station (eNB) than a second user terminal (UEB). Thus coexistence of signals sent by user terminals (UEA, UEB) located at different distances from the base station (eNB) within a same receiver window is enabled without inter-symbol interference. The generated zero-tail signal may also be transmitted from the first user terminal (UEA) or from the base station (eNB) in an outdoor system that is detectable by a neighboring indoor system.Type: GrantFiled: February 12, 2013Date of Patent: January 10, 2017Assignee: Nokia Solutions and Networks OYInventors: Gilberto Berardinelli, Bernard Raaf, Fernando Tavares, Juergen Michel

Patent number: 9544173Abstract: Systems, methods, apparatuses, and computer program products for generating sequences for zero-tail discrete fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (ZT DFT-s-OFDM) reference signals. One method includes adding a zero vector to an input sequence, and performing an iterative manipulation of the input sequence. The performing of the iterative manipulation of the input sequence may include, for example: computing frequency domain response of the sequence, normalizing elements of the computed frequency domain sequence to unitary power while maintaining phase of each of the elements, converting the sequence to time domain, generating a zero-padded sequence by forcing a zero head and tail of the sequence, and repeating the steps until a final sequence with zero-tail and flat frequency response is obtained.Type: GrantFiled: September 15, 2015Date of Patent: January 10, 2017Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Gilberto Berardinelli, Frank Frederiksen, Klaus Ingemann Pedersen, Preben Elgaard Mogensen, Kari Pekka Pajukoski
