Problems solved by technology

The provision of such information increases network complexity, since such information is currently not required for RSRP and RSRQ measurements
Also, due to their sparsity, their measurement performance is not as robust as that based on the currently used cell-specific reference signal CRS

Embodiment Construction

[0049] The drawings are schematic and simplified for the sake of clarity, and they only show details that are essential for the understanding of the embodiments presented herein, while other details are omitted. The same reference numerals are used everywhere for equivalent or corresponding parts or steps.

[0050] Image 6 An example of a radio communication network 100 in which the embodiments herein can be implemented is shown. Even though Image 6 The figure in the figure shows an LTE network. The radio communication network 100 can be any wireless communication system, such as LTE, LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), High Speed ​​Packet Access (HSPA), Global System for Mobile communications / increased data rate GSM Evolution (GSM / EDGE), GSM / GERAN, Worldwide Interoperability for Microwave Access (WiMax), Ultra Mobile Broadband (UMB) or WiFi or WLAN networks or other 3GPP cellular networks or systems. The radio communication network 100 includes a net...

Abstract

Embodiments herein relate to a methods performed by a wireless device (121) for handling discovery signals from one or more transmission points (111, 112) or cells (115, 116) in a radio communications network (100). Embodiments herein further relates to methods performed by a network node (110) for handling discovery signals from one or more transmission points (111, 112) or cells (115, 116) in a radio communications network (100). The method performed by the UE (121) comprises: determining (1101) an identity of a cell associated with received synchronization signals and/or Channel State Information Reference Symbol, CSI-RS, configuration information; and applying(1102) CSI-RS configurations when receiving discovery signals on radio resources associated with CSI-RS based on the determined identity of the cell and/or CSI-RS configuration information. Embodiments of the wireless device (121) and the network node (110) are also described.

Description

Technical field [0001] The embodiments herein relate to designing discovery signaling in a radio communication network. In particular, the embodiments herein relate to wireless devices (such as user equipment), network nodes, and methods thereof for processing discovery signals in a radio communication network. Background technique [0002] In a typical radio communication network, wireless terminals (also referred to as mobile stations), wireless devices, and / or user equipment UEs communicate with one or more core networks via a radio access network RAN. RAN covers a certain geographic area, which is divided into cell areas, where each cell is served by a base station (such as a radio base station RBS) or a network node, which in some networks may also be called, for example, "NodeB", "eNodeB" or "eNB ". [0003] The Universal Mobile Telecommunications System UMTS is a third-generation mobile communication system, which evolved from the second-generation 2G global system for mob...
