DFT-s-OFDM, signal, the method comprising, converting, by a wireless transmitter, complex-valued symbols to polar domain symbols, wherein the complex-valued symbols are modulated using at least phase shift keying, processing, by the wireless transmitter, angle values of the polar domain symbols to avoid angle differences larger than ? rad, or lower than ?? rad, between consecutive angle values, interpolating, by the wireless transmitter, at least the processed angle values by an interpolation factor N/L, wherein L is a length of Fast Fourier Transform, FFT, and Nis length of Inverse FFT, IFFT, converting, by the wireless transmitter, the interpolated angle values into complex domain symbols and generating, by the wireless transmitter, a DFT-s-OFDM waveform comprising said complex domain symbols.

Abstract: Systems, methods, apparatuses, and computer program products for beam management reporting in connected mode discontinuous reception (C-DRX) are provided. One method includes configuring a user equipment (UE) in connected mode discontinuous reception (C-DRX) with a timer that determines at least one of when the UE monitors physical downlink control channel (PDCCH) from channel state information reference signal (CSI-RS) based beams or when the UE monitors PDCCH from synchronization signal block (SSB) based beams.

Abstract: The long term evolution (LTE) of the third generation partnership project may benefit from a long term evolution local area network (LTE-LAN) system, such as a portable LTE-LAN system. Moreover, an LTE-LAN system may benefit from inter-cell interference (ICI) detection for inter portable LTE-LAN interference. A method can include measuring, with a first local access point, a first power of a first uplink sequence and a second power of a second uplink sequence from at least one user equipment. The method can also include determining that the first local access point and a second local access point are interfering with one another based on a comparison of the first power and the second power.

Abstract: An approach is provided for asynchronous distribution of content and notifications of updates to a client. A proxy server causes an establishment of at least one communication connection between at least one proxy client, at least one proxy server, and/or at least one service provider. The proxy server determines one or more updated content items available to the at least one proxy client. The proxy server causes a transmission of the one or more updated content items, one or more notifications regarding the one or more updated content items, or a combination thereof via the at least one communication connection.

Abstract: Methods and apparatuses are provided for context determination. A method may include determining a location identifier. The location identifier may be indicative of a location of an apparatus. The method may further include determining a location cluster based at least in part on the location identifier. The method may additionally include determining a first probability for each of one or more contexts based at least in part on the determined location cluster. The method may also include determining a context of the apparatus based at least in part on the determined first probability. Corresponding apparatuses are also provided.

Abstract: An approach is provided for reducing communication traffic and cost by applying recipient criteria in identity-based encryption. A recipient criterion application selects one or more recipient criteria for data, and encrypts the data using the selected one or more recipient criteria as a public key of identity-based encryption.

Abstract: In the front end of a mobile phone receiver for operation in a network using DSSS signals, detection of a carrier frequency offset in a received PN-modulated signal is performed by first correlating the received signal with a local replica of the PN codes generated within the receiver. The resulting despread signal is integrated over a fixed period, or dwell, of time, then run through a square-law envelope detector. The integration is divided into a plurality of sub-dwells, the values of which are each provided as an input to a Fast Fourier Transform (FFT) to generate a plurality of frequency bins. The magnitude for each FFT frequency bin is computed and a maximum value is selected. The maximum value and its corresponding bin number are saved in the signal processor's memory. The next PN code phase is tested and, depending on the search scheme, this sequence continues until the decision algorithm terminates the search.
