    Abstract: An apparatus may receive, from a source network node, a configuration of a channel bandwidth and a first bandwidth part for receiving data from the source network node, for example during a handover from the source network node to a target network node, and a configuration of a second bandwidth part for receiving data from the target network node. The apparatus may communicate data with the source network node and the target network node with a bandwidth including the first bandwidth part and the second bandwidth part using same protocol stack.

    Abstract: Example embodiments of the present disclosure relate to resource selections of random access procedure. According to embodiments of the present disclosure, when a random access procedure is triggered for a certain feature combination, the terminal device determines the random access channel (RACH) partition to use based on a defined priority order of (RACH-partition) features whenever a RACH partition that would have matched the feature combination for which the RA procedure is triggered is not provided in the cell. The priority order could be pre-defined in the standards, provided by the Mobile Network Operators (MNO), or signaled dynamically by the network via system information or dedicated signaling (e.g., radio resource control (RRC) or medium access control (MAC) signaling). In this way, better resource selections may be achieved. Moreover, it does not need to configure resources for any possible combinations of features.

    Abstract: Various example embodiments relate to configuration of an apparatus to avoid frequency conflicts between activities associated with different subscriptions. The apparatus may receive, from a first network, a measurement configuration comprising an indication of a plurality of frequencies or cells for performing cell measurements. The apparatus may determine, from the plurality of frequencies or cells, at least one non-preferred frequency or cell at which simultaneous operation of the apparatus at the first network and at least one second network is restricted, and transmit, to the first network, an indication of the at least one non-preferred frequency or cell. The first network may be reconfigured to deprioritize use of the at least one non-preferred frequency or cell for the apparatus. Apparatuses, methods, and computer programs are disclosed.

    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.
