Abstract: According to some disclosed embodiments an action is performed by an electronic social agent. The electronic social agent collects a first dataset indicating the user's state, the user's environment state, and a first user response to the performed action. Then, it is determined whether it is desirable to collect a second response from the user and, if so, it is further determined whether to generate a question to be presented to the user based on an analysis of a first dataset and the first user response. Then, an optimal time for presenting the question to the user is determined. A question that is based on the collected data and the first user response is generated by the electronic social agent for actively collecting an additional user response. Then, based on the collected additional user response, the decision-making model of the electronic social agent is updated and improved.

Abstract: Disclosed are example embodiments of systems and methods for hybrid automatic repeat request (HARQ). An example method includes performing a first HARQ compression to reduce a number of HARQ bits, the HARQ compression comprising one of a unified HARQ compression and a block-wise HARQ compression. Optionally, the example method further includes performing a second HARQ compression to further reduce the number of HARQ bits to a compressed number of HARQ bits. One of the first HARQ compression and the second HARQ compression include the unified HARQ compression and another of the first HARQ compression and the second HARQ compression comprising the block-wise HARQ compression. The example method also includes saving the compressed HARQ data to a DDR storage.

Abstract: A method for enabling a wireless communication device to operate in a radio access network as a network relay device to a remote device, using a short range communication channel there between, wherein the communication device receives a control indication signal from the remote device as an indication of future data between the communication device and the remote device via the short range communication channel which forms part of a sidelink communication between the relay device and the remote device; wherein the relay device decodes the control indication signal from the remote device to extract a time allocation for future data.

Abstract: A pedestrian-located UE monitors selected subframes of a sidelink resource to detect periodic transmissions from other mobile devices to assist it in selecting a free resource for its own sidelink transmissions. The subframe selection is based on a cost metric which takes into account a probability of missing detection of a transmission with periodicity p from another mobile device, an average number of transmissions with periodicity p that are expected from another mobile device within a predefined transmission period of the mobile device, and a number of transmission cycles of the mobile device that need to occur in order to have a single potential collision with each periodic transmission from said at least one other wireless communication. The method provides a trade-off between avoiding future collisions and battery life.

Abstract: Methods and apparatus for transmitting and receiving data over a physical channel using a polar code are provided. The polar code defines a plurality of virtual channels within the physical channel and allocates a subset of the virtual channels for the transmission of data. The method for transmitting data: receives a block of data to be transmitted; receives additional data to be transmitted together with the block of data; selects one or more of the virtual channels; determines a scrambling sequence based on the additional data; applies the scrambling sequence to those bits of the block of data to generate a scrambled version of the block of data; and transmits the scrambled version of the block of data according to the polar code.

Abstract: A method includes, in a mobile communication terminal, receiving signals from a base station in a sequence of time frames. Based on the received signals, a classification of the time frames into first and second types is determined in the terminal, such that a level of interference in the time frames of the first type is lower than the level of interference in the time frames of the second type. The received signals are decoded based on the time frames and the corresponding classification.
