Problems solved by technology

Although the delay in acquiring synchronization may be reduced since the first and second synchronization signals are mapped to different subcarriers, this violates the single-carrier property of the transmission, resulting in higher PAPR in the transmitter

Abstract

A mechanism for sending reference signals is provided. A method is performed by a first network device. The method includes sending a composite reference signal to a second network device in a single Orthogonal Frequency Division Multiplexing (OFDM) symbol. The composite reference signal is the time-domain concatenation of at least a first reference signal and a last reference signal. A composite reference signal has a single cyclic prefix. The cyclic prefix is ​​determined from the last part of a single OFDM symbol. Mechanisms for receiving such reference signals are also provided.

Description

technical field [0001] Embodiments presented herein relate to methods, network devices, computer programs and computer program products for transmitting reference signals. Embodiments presented herein further relate to methods, network devices, computer programs and computer program products for receiving reference signals. Background technique [0002] In communication networks, it can be a challenge to obtain good performance and capacity for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed. [0003] For example, one parameter that provides good performance and capacity for a given communication protocol in a communication network is synchronization. [0004] For example, when a wireless device such as a user equipment (UE) is powered on, or when it moves between cells in a cellular wireless radio access sent by the radio access network node of the wireless radio access network). One purpose of t...
