Embodiment 1

[0166]Embodiment 1. A method for handling radio link failure RLF on a first group of cells 115 in a wireless communication network 100 performed by a user equipment UE 120 via the first group of cells 115 and the second group of cells 115 The group cell 116 participates in an ongoing communication with the wireless communication network 100, the method comprising:

[0167] Detecting 501 RLF or, for example, an indication of RLF on one or more of the first set of cells 115,

[0168] sending 502 a report to a network node 111, 112, 130 in the wireless communication network 100 via one or more of the cells in the second group 116, the report including information about the cells in the first group 115 One or more radio link information on the RLF. The report may eg indicate to the network node 110 that the connection is no longer available.

Embodiment 2

[0169] Embodiment 2. The method according to embodiment 1, wherein any one or more of the following:

[0170] The first group of cells includes one or more primary cells PCell,

[0171] The second group of cells includes one or more secondary cells SCell.

Embodiment 3

[0172] Embodiment 3. The method according to any one of embodiments 1-2, further comprising:

[0173] The report indicates to the second network node 112 to handle RLF on one or more of the first set of cells 115 while continuing said communication with the wireless communication network 100 .

Abstract

A method performed by User Equipment (UE) for handling a Radio Link Failure (RLF) on a first group of cells in a wireless communication network is provided. The UE is engaged in an ongoing communication with the wireless communication network via a first group of cells and a second group of cells. The UE detects (501) that an RLF is on one or more out of the first group of cells. The further UE sends (502) a report to a network node in the wireless communication network. The report is sent via one or more out of the second group of cells while continuing the communication with the wireless communication network. The report comprises radio link information about the RLF on one or more out of the first group of cells.

Description

technical field [0001] Embodiments herein relate to user equipment (UE), network nodes and methods therein. In some aspects, they relate to handling radio link failure (RLF) on a first set of cells in a wireless communication network. Background technique [0002] In a typical wireless communication network, a wireless device (also referred to as a wireless communication device, mobile station, station (STA) and / or user equipment (UE)) communicates via a local area network (such as a Wi-Fi network) or a radio access network ( RAN) communicates with one or more Core Networks (CN). The RAN covers a geographical area divided into service areas or cell areas (which may also be referred to as beams or beam groups), and each service area or cell area is accessed by a radio network node (e.g. a radio access node such as Wi-Fi A Node or Radio Base Station (RBS)), which in some networks may also be denoted eg as Node B, eNodeB (eNB) or gNB as denoted in 5G. A service area or cell ...
