Embodiment Construction

[0036] Currently in UTRAN and E-UTRAN the terms Home NodeB or Home eNodeB or Home Base Station are more commonly used. The latter is more general as it includes any type of femtocell. The terms home base station and home Node B are used interchangeably in the remainder of the disclosure. These terms also include Femto base stations, Home eNBs, or similar base station types.

[0037] figure 1 is a schematic diagram illustrating an example embodiment of a wireless communication network 1 . The wireless communication network 1 includes one or more macro base stations 5 (macro BS) and one or more femtocells 7 (Home BS) Mobile core network connected to other core network nodes and systems such as Internet nodes (not shown in the figure), operation and maintenance3 (O&M) subsystem or home NodeB database manager4 (DAM) 2 (MCN). DAM 4 is typically connected to macro BS 5 via a macro BS / DAM interface and to home BS 7 via a home BS / DAM interface. Typically, the MCN 2 communicat...

Abstract

The present disclosure relates to a method and a network node 100 in a wireless communications network 1. In particular, it relates to selecting a frequency band for operation for user equipment 9 in the wireless communications network 1. The frequency band to be selected is either a licensed frequency band or an unlicensed frequency band. The network node 100 is a macro base station 5, or a home base station (7, 700), and is adapted to communicate with user equipments 9 in the wireless communications network 1 which comprises both the macro base station 5 and the home base station (7, 700). The home base station (7, 700) is adapted to support operation in both the licensed frequency band and the unlicensed frequency band. The method comprises obtaining radio condition measurements performed on the licensed frequency band and / or on the unlicensed frequency band; selecting the frequency band, based on the obtained radio condition measurements; and updating the home base station of the selected frequency band to be used for communication with one or more of the user equipments.

Description

technical field [0001] The present disclosure relates to methods and network nodes in a wireless communication network. In particular, it relates to selecting a frequency band for user equipment operation in a wireless communication network. Background technique [0002] Unlicensed frequency bands (spectral bands, frequency bands or operating frequency bands) have long before now been used as an alternative to licensed frequency bands in order to compensate for spectrum scarcity and high licensing costs of spectrum for mobile communications. Spectrum scarcity refers to the fact that there is a lack of spectral resources for cellular communication systems relative to the traffic demands caused by pervasive cellular services such as voice, Internet access and other high bit rate data services. Licensed frequency bands for mobile communications, especially in the frequency range between about 700 MHz and 2 GHz, are scarce because the propagation characteristics in this frequen...
