  • Patent number: 11818615
    Abstract: A method performed by a target access node for handling data packets in a handover of a User Equipment, UE, from a source cell served by a source access node, to a target cell, served by the target access node in a wireless communications network is provided. The target access node receives a status report of last received data packet in the UE from the source access node. The target access node performs a data packet duplication check based on the information comprised in the status report. The target access node then sends to the UE, only data packets which have not already been received by the UE from the source access node, based on the outcome of the duplication check.

  • Patent number: 11818611
    Abstract: Embodiments herein relate to, e.g., a method performed by a source access node relating to handover of a UE. The source access node sends to a target access node, an initial handover preparation message with a first explicit indicator for the target access node to request an enhanced Make-Before-Break Handover. The source access node receives an handover preparation response message from the target access node, with a second explicit indicator accepting or rejecting the requested enhanced Make-Before-Break Handover. Further, the source access node selects a possible fallback mechanism, upon reception of the handover preparation response message from the target access node indicating rejection or no support of enhanced Make-Before-Break Handover.

  • Patent number: 11792711
    Abstract: Systems and methods are provided for improving quality and coverage of a VoNR session on a user device. When a user device is currently engaged in a VoNR session having a voice signal and a data signal, at least one KPI is monitored. The KPI is an indicator that can indicate the quality of the VoNR session, such as RSRP, RSRQ, SINR, or the like. A threshold for the KPI is determined. Once the threshold is met, a handover is initiated for the voice signal without initiating a handover for the data signal.

  • Patent number: 11765627
    Abstract: One or more processors, operating in a source base station and/or a target base station, determines a change in the termination point from the source base station to the target base station for a radio bearer with a current count value according to data unit sequencing. The one or more processors determine (1806) whether a user equipment (UE) changes the data unit sequencing as a result of the change in the termination point. In a first instance, the one or more processors cause the target base station to apply (1810) the current count value to the radio bearer, in response to determining that the data unit sequencing does not change. In a second instance, the one or more processors cause the target base station to apply (1820) a new count value different from the current count value to the radio bearer, in response to determining that the data unit sequencing changes.

  • Patent number: 11743079
    Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.

  • Patent number: 11722999
    Abstract: A communication channel merging system detects that a first communication session that is provided via a first communication channel between a first user and a first service provider is concurrent with a second communication session that is provided via a second communication channel between the first user and a second service provider. The system then generates a user score based on information associated with the first and second communication sessions and determines that the user score satisfies a condition that causes the first and second communication sessions to be merged into a merged communication session. The system generates a first channel score for the first communication channel and a second channel score for the second communication channel and determines based on those channel scores that the first communication channel should provide the merged communication session. The system directs the merged communication session to be provided on the first communication channel.
