Abstract: The present document discloses a solution for tracking distribution of media content. According to an aspect, a computer-implemented method for tracking distribution of media content comprises: storing, in a server computer, a first user account of a first user and a second user account of a second user; associating a media file with information linking the first user account with a vendor; detecting modification of the media file by the second user and, in response to said detecting, associating a modified media file with information linking the second user account with the vendor, the modified media file resulting from said modification; detecting an action linked to the modified media file and to the vendor; and in response to said detecting the action, updating at least one parameter of at least one of the first user account and the second user account.

Abstract: A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.

Abstract: In a first subframe, data is sent by a network node in a DL shared channel and a timing indicator is sent in a PDCCH to UE, the timing indicator indicating an offset relative to the first subframe the UE should use in order to determine a second subframe to use to send, in a PUCCH, acknowledgement information for the data received in the DL shared channel of the first subframe. The acknowledgement information is received by the network node from the UE in the PUCCH of the second subframe. The UE receives the data and timing indicator and determines the second subframe using at least the timing indicator. The UE transmits the acknowledgement information in the PUCCH of the second subframe. Apparatus, computer programs and products, and methods are disclosed.

Abstract: Coexistence of OFDM transmissions with different sampling rates, subcarrier spacing, symbol duration, bandwidths, but a constant FFT size, all with the same integer ratio (downclocking or upclocking) N=2, 4, 8 . . . Now called different numerology. Problem of Time alignment due to the presence of alternating long CP and short CPs in a slot. At the slot level the transmissions are aligned, but not at the symbol level. The application proposes to send after the first symbol for N=1 a so-called Time Alignment Period of same duration for each transmission in order allegedly to allow the network nodes to synchronize their timings or clocks without interfering with the transmission or reception of any symbols or CPs of other transmissions.

At least one different OFDMA parameter and/or format is applied to said control information than to said data. At a receiver the frame or subframe is processed by taking into account the application of the at least one different OFDMA parameter and/or format.
