Embodiment Construction

[0060] Currently in UTRAN and E-UTRAN the term Home NodeB (Home NB) or Home eNodeB (Home eNB) or Home Base Station is more commonly used. The latter is more general as it includes any type of femtocell. The terms Home Base Station (HBS) and Home Node B are used interchangeably in the remainder of this disclosure. These terms also include femto base stations (femto BSs), Home eNBs, or similar base station types.

[0061] Note also that the term HBS may refer to any type of BS capable of serving a localized radio environment such as clubs, offices, homes, indoor shopping malls, and the like. For example, a pico base station or a relay node serving a local area may also be considered a home BS. Similarly, a macro BS refers to any type of BS capable of serving open area radio environments such as outdoor areas, city centers, and the like. For example, a macro base station or an outdoor relay node serving an open area can also be regarded as a macro BS according to the above-men...

Abstract

The present disclosure relates to a method (200) and a network node (100) in a wireless communications network (10). In particular, it relates to a method for controlling a maximum output power of the network node (100) located in the wireless communications network (10), wherein the network node (100) is configured to comprise a Global Navigation Satellite System receiver, GNSS receiver (120). The GNSS receiver (120) is used for receiving signals from the GNSS. The method (200) comprises determining whether a measured GNSS signal transmitted from the GNSS is considered detectable and, if so, determining whether thereceived GNSS signal is received directly from the GNSS (20) or via a GNSS repeater (120). The method further comprises selecting a power control method for controlling the maximum output power of the network node (100), based on a result from the determining.

Description

technical field [0001] The present disclosure relates to methods and network nodes in a wireless communication network. Specifically, it relates to controlling the maximum output power of network nodes located in a wireless communication network. Background technique [0002] Femto base stations, or so-called femtocells, have recently attracted a lot of attention in the wireless industry. The standardization process for femtocells is underway in 3GPP for Evolved Universal Terrestrial Radio Access Network (E-UTRA) and IEEE 802.16. Femtocells are standardized in Release 8 for UTRA. However, in UTRA and E-UTRA advanced features related to femtocells such as mobility procedures, interference management and femtocell control are also introduced for future releases. Femto base stations are already operational in other technologies such as GSM and 3GPP2 CDMA technologies (eg, CDMA2000 1xRTT and High Rate Packet Data (HRPD)). [0003] Femto base stations such as frequency divisi...
