Embodiment Construction

[0038] As described above, when a wide bandwidth of a license-exempt radio frequency band is used for a single wireless link in a wireless communication system and a channel sensing method (such as LBT) generally required for a license-exempt frequency band is used together, there is a difference between LBT using the prior art. Algorithm to control whether the wireless communication device is allowed to transmit the associated question.

[0039] Embodiments herein describe a solution to the above-mentioned problems by enabling a wireless communication device to preferentially select among a plurality of radio frequency bands included in the license-exempt radio frequency band (ie, the license-exempt system bandwidth). In the context of this application, enabling may include or mean allowing.

[0040]A network such as a gNB may define multiple radio frequency bands within the license-exempt system bandwidth. In other words, the network, such as a gNB or gNB, together with one...

Abstract

A method performed by a wireless communications device for accessing an unlicensed radio frequency band. The wireless communications device is configured to operate in the unlicensed radio frequency band. The unlicensed radio frequency band comprises a plurality of radio frequency bandwidth parts and is used by a wireless communications network comprising a network node. The wireless communications device receives, from the network node, an indication enabling the wireless communications device to make a prioritization among the plurality of radio frequency bandwidth parts. The wireless communications device accesses the unlicensed radio frequency band in accordance with the prioritization.

Description

technical field [0001] Embodiments herein relate to network nodes, wireless communication devices and methods therein. In particular, they relate to accessing license-exempt radio frequency bands in wireless communication networks. Background technique [0002] A wireless communication device such as a terminal is also referred to as eg User Equipment (UE), mobile terminal, wireless terminal and / or mobile station. These terms will be used interchangeably below. A wireless communication device is capable of communicating wirelessly in a wireless communication network, such as a wireless communication network or a cellular communication network. A wireless communication network may also be referred to as a wireless communication system, sometimes also called a cellular radio system or a cellular system. It can be, for example, between two wireless communication devices, between a wireless communication device and a conventional phone, and / or between a wireless communication...
