Abstract: Various communication systems may benefit from the appropriate control of the timing of communication. For example, certain wireless communication systems may benefit from packet data convergence protocol windows, for example in the case of split bearers being in use. A method can include transmitting a plurality of protocol data units over a bearer mapped to a plurality of logical channels. The protocol data units can be transmitted in a radio link control unacknowledged mode. The method can also include managing at least one transmission characteristic of the transmitted plurality of protocol data units.

Abstract: A method is provided where handover information about one or more target beams of a target cell is provided. The beam quality of those target beams is determined along with beam quality of one or more other beams of the target cell. Dedicated uplink resources associated with the target beams and shared uplink resources are associated with the other beams. It is determined based on the beam quality which of the target and other beams is to be used to initiate a connection to the target cell.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for proactive triggering of handovers in wireless communication networks. In one example implementation, the method may include receiving, by a user equipment (UE), handover configuration information from a first network node of a plurality of network nodes, estimating rate of change values of reference signal (RS) difference measurements, a reference signal (RS) difference measurement being a difference in reference signal (RS) measurements between the first network node and a second network node of one or more second network nodes, comparing the rate of change values with the mapping information received from the first network node, determining one or more timeToPreTrigger values based on the comparison, initiating one or more timeToPreTrigger timers based on the corresponding one or more timeToPreTrigger values, the one or more timeToPreTrigger timers corresponding to different second network nodes, generating one or more measurement reports upon expiration of the one or more timeToPreTrigger timers, and transmitting the one or more measurement reports to the first network node. In an another example implementation, the method may include transmitting, by a first network node of a plurality of network nodes, handover configuration information to a user equipment (UE), receiving a measurement report from the user equipment (UE), the measurement report corresponding to at least one second network node of the one or more second network nodes, selecting, based on the measurement report, a second network node of the one or more second network nodes for performing a handover, and transmitting an indication to the user equipment (UE) about performing the handover to the selected second network node based on the indication.

Abstract: According to an example implementation, a method may include transmitting, by a user device to a base station in a wireless network, a system information request for on-demand system information during a random access procedure, where the system information request is a request for one or more parameters that enable the user device to communicate in the wireless network, receiving, by the user device from the base station, an indication of a wait period in which the user device waits before obtaining the on-demand system information, waiting, by the user device, a time duration during the wait period, and monitoring, by the user device after expiration of the wait period, a system information window in which a system information message having the on-demand system information is broadcasted by the base station.

Abstract: An example embodiment relates to Random Access Channel, RACH, procedure, for example in the New Radio, NR. Random access procedures may be of two types, contention based CBRA and contention free, CFRA. A client device may only perform CBRA fallback when none of the reference signal received strengths, RSRPs, of the synchronization signal blocks, SSBs, which is associated with the CFRA resources is above a predefined threshold, T1. All SSBs and CSI-RS with associated CFRA resources may be below the threshold. Then, the client device may select an SSB or CSI-RS according to a predefined rule and perform CFRA when CFRA resources are associated. Devices, methods and computer programs are disclosed accordingly.
