  • Patent number: 12389284
    Abstract: Embodiments herein relate to for example a method performed by a radio network node for handling a communication of a user equipment, UE, in a wireless communication network. The radio network node transmits a handover command for handing over the UE, from a source cell to a target cell, wherein a security parameter for encrypting data communicated between the radio network node and the UE is retained during the handover. Furthermore, the radio network node maintains a sequence number status for reception and/or transmission of a signalling radio bearer of the UE during the handover from the source cell to the target cell, and/or at a fallback from the target cell to the source cell, when the UE triggers the fallback to the source cell.

  • Patent number: 12381668
    Abstract: Techniques are provided to enable use of more than two preamble group Bs during random access (RA) for connected UEs. This flexibility is achieved by configuring the active BWP to overlap with the 2-step RA resources on the initial BWP, configuring different sizes of preamble group B in the initial BWP and the active BWP, a allowing connected UEs in the active BWP to use the MsgA PRACH and MsgA PUSCH resources in the initial BWP without switching active BWP.

  • Publication number: 20250240225
    Abstract: Embodiments herein relate to, for example, a method performed by a user equipment, UE, (10) for handling communication in a wireless communications network. The UE (10) receives from an upper layer an indication relating to a quality of experience, QoE, process; and applies the indication in one or more messages and/or for one or more bearers. The UE (10) applies the indication by selecting a message type and/or a bearer type to send the indication to a radio network node depending on a type of a QoE measurement and/or a criticality of the QoE measurement of the indication.

  • Patent number: 12369193
    Abstract: A method for accessing a cellular communications network in unlicensed spectrum is provided. More specifically, the method is related to performing a Listen-Before-Talk (LBT) procedure prior to transmitting a Physical Random Access Channel (PRACH) preamble for accessing a New Radio-Unlicensed (NR-U) network. A User Equipment (UE) first performs the LBT procedure. If the LBT procedure is successful, the UE then generates a punctured PRACH preamble and transmits the punctured PRACH preamble. By puncturing the PRACH preamble, it is possible to create a gap(s) for performing the LBT procedure in a way that is backward compatible with existing NR-U specification and does not reduce a number of random access occasions in a slot or a mini-slot. As a result, it is possible to transmit PRACH preambles in consecutive random access occasions, thus helping to increase spectrum utilization and reduce latency in the cellular communications network.

  • Publication number: 20250219915
    Abstract: Embodiments include methods for distributing quality-of-experience (QoE) measurements performed by user equipment (UEs) in a radio access network (RAN). These methods are performed by a first network node or function (NNF) of the RAN and include receiving one or more fourth messages from a second NNF of the RAN. Each fourth message includes one or more RAN-visible QoE (RVQoE) measurement reports, each RVQoE measurement report includes one or more RVQoE metrics or values, and each RVQoE metric or value is based on QoE measurements performed by a particular UE that is associated with the first NNF. Such methods also include sending to the second NNF a first message including a request to stop sending RVQoE measurement reports to the first NNF. Other embodiments include complementary methods for the second NNF, as well as NNFs configured to perform such methods.

The method comprises obtaining a trigger to perform the handover and establishing a radio connection for the at least one radio bearer with the target access node. An uplink transmission of PDCP SDUs is switched from the source to the target access node over the established radio connection. A radio connection with the source access node is released and a PDCP status report is transmitted to the target access node for each configured radio bearer. The respective PDCP status report indicates PDCP Sequence Numbers (SNs) of missing PDCP SDUs.
