摘要： This document discloses a solution for modulating and demodulating signals transferred over a communication channel. According to an aspect, a method comprises: storing a database for mapping rules for mapping a block of N bits into M modulation symbol phase transitions, wherein a phase transition between consecutive modulation symbols is limited to less than or equal to ∓π/2, wherein M is smaller than N, and wherein M is the smallest number required for realizing 2N different phase-transition combinations; determining an initial phase; acquiring a block of N bits and modulating the block of N bits into M phase symbol transitions from the initial phase by using bit values of the block of N bits and the mapping rules, thus acquiring M modulation symbols; performing said determining, acquiring, and modulating for further blocks of N bits, thus acquiring a sequence of K modulation symbols; allocating the sequence of K modulation symbols to sub-carriers of a multi-carrier symbol and causing transmission of the multi-carrier symbol over a radio interface.

摘要： This document discloses a solution for occupying time-frequency resources for a wireless transmission. According to an aspect, a method comprises: determining time-frequency resources in a channel configuration, wherein the time-frequency resources is a combination of a first number of frequency resources and a number of time resources, wherein the first number of frequency resources is defined in units of consecutive resource blocks each having a determined number of resource elements; determining whether or not the first number of frequency resources is expressible as 2a·3b·5c where [a, b, c] are non-negative integers, and in case the first number of frequency resources is not expressible as 2a·3b·5c, determining a second number of frequency resources and a third number of frequency resources in the first number of frequency resources, wherein the second number of frequency resources is expressible as 2a·3b·5c, wherein the third number of frequency resources is not overlapping with the second number of frequency resources; occupying the second number of frequency resources within the number of time resources with information symbols and occupying the third number of frequency resources within the number of time resources for a wireless transmission; and generating and causing the wireless transmission comprising the occupied frequency resources.
