    摘要: Methods and apparatus, including computer program products, are provided for user-plane switching of traffic for dual connectivity. In some example embodiments, there is provided a method. The method may include receiving, at a serving gateway, an indication to persist a first tunnel identifier located at a master base station, while the serving gateway sends, towards a second tunnel identifier located at a secondary node, user plane traffic for a user equipment in dual connectivity with the master base station and the secondary node; and switching, at the serving gateway, the user plane traffic between the second tunnel identifier and the first tunnel identifier, when the serving gateway receives, via a user plane, an error indication and/or a switch indication. Related apparatus, systems, methods, and articles are also described.

    摘要: This document discloses a solution for using low-density parity check codes in connection with a retransmission scheme in a wireless network. According to an aspect a method comprises: encoding, by a first apparatus, a data bit set by using a first parity check matrix in a low-density parity check encoder, thus providing a first parity bit set; causing, by the first apparatus, transmission of the data bit set and at least some parity bits of the first parity bit set to a second apparatus in a message; determining, by the first apparatus, that the second apparatus was not capable of decoding the data bit set; modifying, by the first apparatus, the first parity check matrix by using an overlapping matrix such that overlapping elements of the first parity check matrix and the overlapping matrix are combined, thus acquiring a second parity check matrix; encoding, by the first apparatus, the data bit set by using the second parity check matrix in the low-density parity check encoder, thus providing a second parity bit set; and causing transmission of at least some parity bits of the second parity bit set to the second apparatus.

    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.
