Embodiment Construction

[0018] figure 1 An example of a wireless communication network 100 is depicted in which embodiments herein may be implemented. The wireless communication network 100 may be any wireless system or cellular network, such as a Long Term Evolution (LTE) network, any Third Generation Partnership Project (3GPP) cellular network, Worldwide Interoperability for Microwave Access (Wimax) network, Wireless Local Area Network (WLAN / Wi-Fi), LTE Advanced or fourth-generation (4G) networks, fifth-generation (5G) or New Radio (NR) networks, etc.

[0019] The wireless communication network 100 includes multiple cells, in figure 1 Two of them are depicted in : a first cell 110 comprising a first network node 120 and a second cell 112 comprising a second network node 122 . The first network node 120 serves the first cell 110 and the second network node 122 serves the second cell 112 . The first network node 120 and the second network node 122 are network access nodes, each of which may be eg...

Abstract

A wireless communication device (130) for adapting a radio frequency reception bandwidth and a method therein are disclosed. The wireless communication device (130) is configured to obtain information about respective bandwidths and center frequencies of the first and second channels. The wireless communication device (130) is further configured to determine a total receive bandwidth to use at a time based on respective bandwidths and time instants for receiving the first and second channels, and to adapt the wireless communication device based on the determined total receive bandwidth. The radio frequency receive bandwidth in a communication device.

Description

technical field [0001] Embodiments herein relate to wireless communication devices and methods therein. In particular, they relate to adapting radio frequency receive bandwidth in wireless communication devices. Background technique [0002] Such as Global System for Mobile Communications (GSM) network, Wideband Code Division Multiple Access (WCDMA) or High Speed ​​Packet Access (HSPA) network, 3G Long Term Evolution (LTE) network, Worldwide Interoperability for Microwave Access (Wimax) network, Wireless Local Area Network Wireless communication networks such as (WLAN / Wi-Fi), LTE-Advanced or fourth generation (4G) networks typically cover a geographical area divided into cell areas. Each cell area is served by a base station, which may also be called a network (NW) node, eNodeB (eNB), gNodeB, access node, etc. A wireless communication network may include a number of cells that can support communication for a number of wireless communication devices or user equipments (UEs)...
