METHOD OF SHIFTING REDUNDANCY VERSION FOR THE TRANSMISSION OF A TRANSPORT BLOCK OVER MULTIPLE SLOTS
Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.

VIDEO AND IMAGE CODING WITH WIDE-ANGLE INTRA PREDICTION
A method for directional intra prediction comprises receiving an indication of an intra prediction mode for an image block, and determining a directionality of the intra prediction mode by interpreting the intra prediction mode. The interpreting comprises selecting the directionality from a set of directions consisting of a set of narrow angle directions ranging from -45 to +45 degrees, and a set of wide angle directions above +45 degree angle with respect to either a directly horizontal or directly vertical direction. The number of the wide angle directions in the set of wide angle directions is determined based on the width and height of the image block.

VIDEO AND IMAGE CODING WITH WIDE-ANGLE INTRA PREDICTION
The invention relates to a method for decoding, comprising receiving a bitstream comprising encoded image data, forming from the bitstream in a computer memory a set of reference pixels having reference pixel values for intra-picture directional prediction, predicting a pixel value in a predicted image block (P) by intra-picture directional prediction by using values of one or more selected reference pixels (410, 420) in forming a predicted a pixel value, wherein the selected reference pixels (410, 420) are selected from a prediction direction with respect to the predicted pixel, and wherein the prediction direction between the reference pixel (410) and the predicted pixel can be a wide-angle prediction direction that forms an obtuse angle with top-left direction, repeating the pixel prediction for a number of pixels to form a predicted image block, and using the predicted image block (P) in decoding an image block from the bitstream to obtain a decoded image block. A corresponding method for decoding as well as a decoder, an encoder, computer program products for the same purpose, and a signal are provided.

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.
