Abstract: There is provided controlling radio channel measurements on radio channels of different wireless networks. A wireless communication device performs first radio channel measurements on a first radio channel of a first wireless communication network and second radio channel measurements on at least one second radio channel of a second wireless communication network. It is determined, on the basis of the first radio channel measurements and the second radio channel measurements, a relationship between the first radio channel and the at least one second radio channel. Measurement activity of the at least one second radio channel is controlled on the basis of at least the determined relationship and the first radio channel measurements.

Abstract: Systems, methods, apparatuses, and computer program products for packet combining for PDCP duplication, e.g., in ultra-reliable low-latency-communication (URLLC) scenarios are provided. One method may include providing, from a network node to at least one second node, a pointer to an earlier or first transmission of a protocol data unit (PDU). The pointer may be used by subsequent transmissions of the protocol data unit (PDU) through the at least one second node to indicate to a user equipment (UE) what transmissions are to be combined.

Abstract: There are provided measures for enabling/realizing stationarity-based UE power saving, specifically network-assisted power saving at a terminal entity based on local stationarity monitoring and autonomous power saving mode switching. Such measures exemplarily include that a terminal entity operates in a normal power mode, including performing normal radio environment related measurements (such as regular radio resource management measurements and/or cell search measurements) and monitoring a stationarity condition with a local procedure and/or equipment, switches from the normal power mode to a power saving mode, if the locally monitored stationarity condition is satisfied, and operates in the power saving mode, including performing relaxed radio environment related measurements (such as relaxed radio resource management measurements and/or cell search measurements).

Abstract: Disclosed are two methods, the first method comprising receiving a plurality of data packets, producing a coded data packet by coding together at least two data packets, wherein at least one of the at least two data packets is comprised in the received plurality of data packets or in a coding buffer, transmitting the at least two data packets to a first subset of legs, transmitting the coded data packets to a second subset of legs, and determining if the at least two data packets are to be duplicated based on, at least partly, one or more of the following: a notification, a condition, or a first indication. The second disclosed method comprises receiving a data packet and an indication of a coding function and parameters used for coding two or more data packets, determining if the received data packet is a coded data packet and if it is, determine if one or more internal buffers comprise a minimum set of data packets for generating the coded data packet, using sequence numbers assigned to each data packet, and if the one or more internal buffers comprise the minimum set of data packets, retrieve the minimum set of data packets from the one or more internal buffers, and decoding the coded data packet using the minimum set of data packets and the coding function and parameters indicated by the indication received.

Abstract: An apparatus may be configured to: determine an anticipated change in a transmit power of a cell, wherein the apparatus is connected to a network via the cell; perform one or more measurements related to the cell; modify the one or more measurements based, at least partially, on the anticipated change in the transmit power of the cell; and transmit a measurement report in response to the anticipated change in the transmit power of the cell, wherein the measurement report is based, at least partially, on the one or more modified measurements. An apparatus may be configured to: determine to change a transmit power to a user equipment for a first cell; transmit, to the user equipment, at least one message; initiate the change in the transmit power over a time period; and receive, from the user equipment, a measurement report in response to the at least one message.

Abstract: Systems, methods, apparatuses, and computer program products for user equipment (UE) context duplication. In certain embodiments, when a UE may resume at a target network node within its configured radio area, a duplication of a UE context may occur at the target network node, and the target network node may allocate an additional/secondary identifier to the UE. The secondary identifier may indicate the UE's identity within the network. When configured with a secondary identifier, the UE may retain an original/primary identifier assigned by the anchor network node. The anchor network node may retain the UE context and may maintain user plane connectivity to a core network. The UE may use this primary identifier for operations within the configured radio area, whereas the secondary identifier may be used when resuming operations to a cell that is outside of the configured radio area.
