Abstract: Various communication systems may benefit from relaxed performance requirements. For example, long term evolution (LTE), and in particular heterogeneous networks (HetNet) as well as small cell detection and discovery in small cell deployments in general, may benefit from relaxed performance requirements for offloading measurements. A method can include determining whether a user equipment is in active data transfer. The method can also include using a relaxed performance requirement with respect to a plurality of gap bursts when the user equipment is determined not to be in active data transfer.
Abstract translation: 各种通信系统可能受益于放松的性能要求。 例如，一般来说，长期演进（LTE），特别是异构网络（HetNet）以及小型小区部署中的小型小区检测和发现可能受益于卸载测量的放松性能要求。 一种方法可以包括确定用户设备是否处于活动数据传输中。 该方法还可以包括当确定用户设备不处于活动数据传输时使用关于多个间隙突发的放松的性能要求。

IPC: H04W28/08
Abstract: A method including using master cell group resources for a downlink data transmission to a user equipment, wherein the user equipment is configured with at least one secondary cell group terminated split bearer and a secondary cell group is deactivated; determining, at a centralized central unit user plane, when secondary cell group resources of the deactivated secondary cell group are needed, wherein the determining is based, at least partially, on a data volume threshold for a data radio bearer as configured by a central unit control plane; and based upon the determining that the secondary cell group resources are needed, sending a notification to the central unit control plane to trigger activation of the secondary cell group resources.

Abstract: Systems, methods, apparatuses, and computer program products for beam tracking to reduce latency. A method may include receiving from a network node, a radio resource control reconfiguration message. The method may also include sending a radio resource control reconfiguration complete message in response to the radio resource control reconfiguration message. The method may further include performing radio resource management measurements according to information contained in the radio resource control reconfiguration message. In addition, the method may include preparing a measurement report based on the radio resource management measurements. Further, the method may include sending the measurement report to the network node. The method may also include maintaining a spatial relation with a cell or a carrier that is identified in the measurement report, as indicated in the radio resource control reconfiguration message.

Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell. The message may inform the base station of the source cell that an autonomous handover is initiated. The method may also include initiating the sending of the message to the base station of the source cell during the duration of time Tamer to indicate of the measurement condition. In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.
