摘要： Various communication systems may benefit from an improved transmission of a sounding reference signal. For example, certain communication systems may benefit from an enhanced sounding reference signal transmission via antenna switching or repetition. A method includes receiving a signaling indication at a user equipment from a network entity. The signaling indication indicates a configuration for sounding reference signal transmission via at least one of antenna switching or repetition using a resource group. The resource group comprises a plurality of resources that are either adjacent or have a limited time interval between at least two of the plurality of resources within the resource group. The method also includes transmitting the sounding reference signal from the user equipment to the network entity via at least one of the antenna switching or the repetition using the resource group, wherein the resource group comprises a common characteristic, wherein the common characteristic comprises at least one of a sounding reference signal bandwidth, frequency hopping bandwidth, number of antenna ports, or a period to simplify configuration signaling of the sounding reference signal.
