Embodiment Construction

[0071] The figures are schematic and simplified for clarity, and they only show details that are important for understanding the embodiments, while other details are omitted. Wherein, the same reference numerals are used for the same or corresponding parts or steps.

[0072] Figure 12 A telecommunications system 100 is depicted in which embodiments herein may be implemented. The cellular communication system 100 is a wireless communication network, such as LTE, WCDMA, GSM network, any 3GPP cellular network, or any cellular network or system.

[0073] The telecommunications system 100 comprises a base station, which is a network node and is therefore referred to herein as network node 110 . The network node 110 serves a cell 115 . In this example, the network node 110 may be, for example, an eNB, eNodeB, or Home NodeB, Home eNodeB, femto base station (BS), pico BS, or a user equipment or machine type capable of serving a user located in a cell 115 in the telecommunications ...

Abstract

A method in user equipment for estimating a channel upon receiving an enhanced control channel, eCCH, from a network node in a telecommunications system. The eCCH is distributed over multiple resource block pairs, wherein each of the multiple resource block pairs comprises a number of resources. Each resource is associated with a respective antenna port. The user equipment identifies an antenna port being associated with more than one resource. The more than one resource is present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. The identifying is based on how the eCCH is mapped to the multiple resource block pairs. Also, the user equipment estimates the downlink channel for the eCCH based on the identified antenna port in the more than one resource in the multiple resource block pairs. User equipment, a method in network node and a network node are also provided.

Description

technical field [0001] Embodiments herein relate to network nodes, user equipment and methods thereof. In particular, embodiments herein relate to the transmission and processing of enhanced control channels (eCCH) in telecommunication systems. Background technique [0002] Many different technologies are used in today's radio communication networks, such as Long Term Evolution (LTE), LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global Mobile Communications Systems / Enhanced Data Rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMAX) or Ultra Mobile Broadband (UMB). The radio communication network comprises radio base stations providing radio coverage over at least one respective geographical area forming a cell. A cell definition can also contain the frequency band used for transmission, which means that two different cells can cover the same geographical area, but use different frequency bands. A user equipment (UE) i...
