Abstract: According to some embodiments, a method performed by a wireless device comprises receiving a wireless signal Rk over all subcarriers allocated to the wireless device. The signal Rk comprises a phase tracking reference signal (PT-RS) on a subset of subcarriers allocated to the wireless device and the subset comprises at least one non-contiguous subcarrier. The method further comprises computing a de-inter-carrier interference (ICI) filter based on the PT-RS and a channel estimate using a convolutional matrix CR of the received signal Rk and applying the de-ICI filter to the received signal Rk to generate a de-ICI filtered signal.

Abstract: The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

Abstract: There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting communication signaling in a transmission timing structure, the communication signaling including leading reference signaling in a leading time interval at the beginning of the transmission timing structure and including trailing reference signaling in a trailing time interval at the end of the timing structure. The leading reference signaling starts with a first reference signaling time-domain sequence, and the trailing reference signaling ending with the first reference time-domain signaling sequence. The disclosure also pertains to related devices and methods.

Abstract: According to certain embodiments, a method by a transmitter is provided for adaptively generating precoder bits for a Polar code. The method includes acquiring at least one configuration parameter upon which a total number of precoder bits depends. The at least one configuration parameter comprising at least one of an information block length K,a code block length N, and/or a code rate R=K/N. The total number of precoder bits is determined, and the precoder bits for a code block are generated according to the determined total number of precoder bits. The precoder bits are placed within the code block.
