Embodiment Construction

[0047] The drawings are schematic and simplified for the sake of clarity, and they only show details necessary for the understanding of the embodiments presented herein, while other details have been omitted. Throughout the application, the same reference numerals are used for identical or corresponding parts or steps.

[0048] Figure 5 A wireless communication network 100 is depicted in which embodiments herein may be implemented. In some embodiments, the wireless communication network 100 may be a radio communication network such as a Long Term Evolution (LTE) network. Although the radio communication network is exemplified herein as an LTE network, the radio communication network may also employ any of the following technologies: LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications / GSM Enhanced Data Rates Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax), Ultra Mobile Broadband (UMB) or GSM, 5G ...

Abstract

A method performed by a communication node (110, 121) for transmission using a precoded multi-carrier modulation scheme in a wireless communication network (100) is provided. The communication node divides the precoded multi-carrier symbols into at least a first symbol portion and at least a second symbol portion. Furthermore, the communication node modulates at least the first symbol part and the second symbol part such that the first symbol part of the precoded multicarrier symbol is used for the transmission of the reference signal and the second symbol part of the precoded multicarrier symbol Used for the transmission of data and / or control information. The communication node then sends the reference signal and data and / or control information in the modulated precoded multi-carrier symbols.

Description

technical field [0001] Embodiments herein relate to precoded multi-carrier transmissions in wireless communication networks. In particular, embodiments herein relate to communication nodes and methods therefor for transmission in a wireless communication network using a precoded multi-carrier modulation scheme. A communication node may be a wireless device or a network node in a wireless communication network. Background technique [0002] In a typical radio communication network, wireless terminals (also called mobile stations, terminals and / or user equipment UE) communicate with one or more core networks via a radio access network RAN. A radio access network covers a geographical area divided into cell areas, each cell area is served by a base station or a network node such as a radio base station RBS, which in some networks may also be referred to as eg "NodeB", "eNB" or "eNodeB". [0003] The Universal Mobile Telecommunications System UMTS is a third-generation mobile...
