Problems solved by technology

Therefore, doubling the packet length is wasteful, increases the occupancy of the channel medium, leads to reduced gain in time-varying wireless channels and limits the performance of the communication network

Embodiment Construction

[0038] Embodiments herein relate generally to communication networks. figure 2 is a schematic overview depicting a communication network 1 . The communication network 1 includes one or more RANs and one or more CNs. The communication network 1 may use a number of different technologies such as Wi-Fi, Long Term Evolution (LTE), LTE-Advanced, 5G, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications / Enhanced Data Rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax), or Ultra Mobile Broadband (UMB), to name just a few possible implementations. Embodiments herein relate to recent technology trends using Wi-Fi (eg 5G networks), however, embodiments are also applicable to further developments of existing communication systems (eg WCDMA and LTE).

[0039] In a communication network 1, wireless devices such as mobile stations, non-access point (non-AP) STAs, STAs, user equipment, and / or wireless terminals (for...

Abstract

Embodiments herein relate to a method performed by a transmitting communication device (110) for transmitting data to a receiving communication device (112) in a communication network (1) supporting multi-carrier modulation. The transmitting communication device (110) applies, to the data, a modulation and coding scheme forming constellation symbols. The transmitting communication device (110) maps the constellation symbols to radio resources of a first multi-carrier symbol and to radio resources of a second multi-carrier symbol. The first and second multi-carrier symbols are consecutive multi-carrier symbols. The transmitting communication device (110) refrains from mapping a constellation symbol to a first radio resource of the first multi-carrier symbol having a same sub-carrier centerof frequency as a second radio resource of the second multi-carrier symbol with a mapped constellation symbol. The transmitting communication device (110) transmits the first multi-carrier symbol andthe second multi-carrier symbol to the receiving communication device (112).

Description

technical field [0001] Embodiments herein relate to sending communication devices, receiving communication devices, and methods for wireless communication performed therein. In addition, computer programs and computer readable storage media are also provided herein. In particular, embodiments herein relate to sending data to a receiving communication device in a communication network. Background technique [0002] In a typical communication network, a wireless device (also referred to as a wireless communication device, mobile station, station (STA) and / or user equipment (UE)) communicates with one or more core networks via a radio access network (RAN) . The RAN covers a geographical area divided into service areas or cell areas, where each service area or cell area is served by a radio network node, for example a radio access node (such as a WiFi access point) or a radio base station (RBS), It may also be denoted eg "NodeB" or "eNodeB" in some networks. A service area o...
