Embodiment Construction

[0047] The drawings are schematic and simplified for the sake of clarity, and they show only details necessary for an understanding of the embodiments presented herein, while remaining details have been omitted. Throughout the application, the same reference numbers 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, 5...

Abstract

A method performed by a communication node (110, 121) for transmission using a precoded multi-carrier modulation scheme in a wireless communications network (100) is provided. The communication node splits a precoded multi-carrier symbol into at least a first symbol part and at least a second symbol part. Also, the communication node modulates the at least first and second symbol parts such that the first symbol part of the precoded multi-carrier symbol is used for transmission of a reference signal and the second symbol part of the precoded multi-carrier symbol is used for transmission of data and / or control information. Then, the communication node transmits the reference signal and the data and / or control information in the modulated precoded multi-carrier symbol.

Description

technical field [0001] Embodiments herein relate to precoded multi-carrier transmissions in wireless communication networks. In particular, the embodiments herein relate to communication nodes and methods therein for transmission using a precoded multi-carrier modulation scheme in a wireless communication network. 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 referred to as 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 geographic area divided into cell areas, each cell area being served by a base station or a network node such as a radio base station RBS, which in some networks may also be called eg "NodeB", "eNB" or "eNodeB". [0003] The Universal Mobile Telecommunications System UMTS is a third generation mo...
