A method and a User Equipment, UE, for handling multiple Bandwidth Parts, BWPs, when being connected to a wireless network. The UE is configured to obtain from the network a configuration for use when autonomously switching from a source BWP to a target BWP, said configuration indicating one or more transmissions that the UE can start in the target BWP during a BWP switch. When detecting that the UE is subjected to a trigger event in the source BWP, wherein the trigger event triggers an autonomous BWP switch, the UE transmits to the network in the target BWP a BWP switch request, and the UE also performs at least one further transmission indicated by the obtained configuration.

A network node, a wireless communication device and methods therein for monitoring interferences between a number of groups of wireless communication devices and configuring SL resources for the number of groups of wireless communication devices in a wireless communication network are disclosed. The network node configures a discovery signal associated with an identity and configures which wireless communication devices in which groups to transmit and/or receive the configured discovery signal. The network node determines whether the number of groups of wireless communication devices () are isolated from each other based on a report related to the discovery signal and decides whether or not to reconfigure the SL resources for the number of groups or rearrange the wireless communication devices in the groups based on the determined result on whether the number of groups of wireless communication devices () are isolated from each other.

Embodiments include methods, performed by a user equipment (UE), for uplink (UL) transmission on a shared channel in a cell of a radio access network (RAN). Such methods include determining that the shared channel is unavailable for UL transmission of pending data during a first transmission opportunity. This determination can be based on performing a listen-before-talk (LBT) procedure on the shared channel. Such methods include determining that further data for UL transmission is available before a second transmission opportunity that is after the first transmission opportunity, and determining whether the pending data or the further data should be prioritized for UL transmission during the second transmission opportunity. This prioritization determination can be based on various factors. Such methods can also include transmitting the pending data or the further data, during the second transmission opportunity, based on the prioritization determination. Other embodiments include UEs configured to perform such methods.

Adapting periodic configurations based on spatial relations

The present disclosure relates to telecommunications. In one of its aspects, the disclosure concerns a method in a source User Equipment (UE) for group transmissions in a wireless communications system comprising a group of UEs, including the source UE. The group is assigned a first group IDentity (ID). The source UE has data to be cooperatively transmitted by the group of UEs in a group transmission to a Radio Access Network (RAN) node. The method comprises transmitting, to the group of UEs, a SideLink (SL) message. The SL message comprises the data to be transmitted to the RAN node, a source UE ID identifying the source UE, the first group ID identifying the group of UEs receiving the data and an indicator indicating that the data comprised in the SL message is to be transmitted cooperatively by the group of UEs in a group transmission to the RAN node.
