Abstract: There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting millimeter-wave signaling in a transmission timing structure, the transmission timing structure including N time interval elements sequentially ordered in time, the millimeter-wave signaling includingN separate signaling structures, each signaling structure being transmitted in a different one of the time interval elements. N is an integer multiple of 2. A first subset of the N separate signaling structures corresponds to control signaling, the subset including 2^m signaling structures consecutive in time beginning with the signaling structure of the first time interval element, and m is an integer such that 2^m

Abstract: According to some embodiments, a method performed by a network node for communicating using time division duplexing (TDD) on a first radio access technology (RAT) carrier located within a frequency band of a second RAT comprises transmitting a first communication on the first RAT carrier to a first wireless device. A carrier center frequency of the first RAT carrier aligns with a middle of a resource block (RB) of the second RAT. In particular embodiments, the location of the center carrier frequency of the first RAT satisfies raster requirements of the first RAT.

Abstract: A method, system and apparatus for low complexity intercarrier interference (ICI) compensation algorithms and cyclic block phase tracking reference signal (PTRS) sequence design are disclosed. According to one aspect, a method in a network node includes generating a PTRS, having a PTRS sequence that is configured to lower a complexity of an ICI compensation algorithm. According to another aspect, a method in a wireless device (WD) includes determining an ICI compensation algorithm based at least in part on a PTRS having a PTRS sequence, and applying the determined ICI compensation algorithm to compensate for ICI.

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.
