Abstract: The disclosure relates to an apparatus comprising: means for sending (500) a duplicate sidelink transmission to a user equipment on each carrier of a group of carriers; means for receiving (502) feedback from the user equipment for each carrier; and means for determining (504) a sidelink carrier aggregation capability of the user equipment on the group of carriers based on the feedback.

Abstract: Multiple techniques for testing a UE by a Test Equipment (TE) are disclosed. A TE configures with a procedure of performance testing of data transmission to be performed while the UE is in an inactive state. The TE performs the performance testing, wherein the procedure includes at least one of: triggering the data transmission while the UE is in the inactive state; transmitting one or more test data packages; controlling time that the UE starts to transmit, while in the inactive state, payload corresponding to the test data package(s); verifying whether or not conditions for the data transmission are met; or determining whether or not the UE passed the performance testing, based on a result of the verification of whether or not conditions for the data transmission are met. The UE performs the data transmission and can send measurement results. There are multiple conditions that can be tested.

Abstract: This document discloses a solution for adaptive transmission of data packets. According to an aspect, a method comprises: scheduling a first wireless interface of a user device to operate in a first transmission mode where the first wireless interface transmits payload data to a wireless network; scheduling a second wireless interface of the user device or another user device to operate in a second transmission mode where the second wireless interface transmits keep alive messages without payload data to the wireless network or to another wireless network; receiving at least one measured connection quality metric from the first wireless interface and from the second wireless interfaces; and rescheduling, on the basis of the received connection quality metrics, a transmission mode of at least one of the first wireless interface and the second wireless interface.

Abstract: A relay discovery may be performed by apparatuses acting as relay nodes sending first messages indicating existence of a relay capable node and user nodes monitoring the first messages. However, the relay nodes are configured to monitor broadcasted second messages, a second message being broadcasted by a user node that has determined it has a lack of sufficiency of link redundancy. The second message indicates a fast link discovery request for sidelink communications with service of quality requirements.

Abstract: An apparatus, method, computer program product and system for: receiving information relating to available connections in a wireless network, the wireless network comprising at least one access node and at least one sidelink device, collecting information relating to a mobility pattern of at least one moveable device within a predetermined area covered by the wireless network, establishing a first data connection to the wireless network for the moveable device, predicting, based on the mobility pattern of the moveable device and the information relating to the wireless network, a second data connection to be established to the wireless network for the moveable device, and sending, in response to determining that at least one criterion related to the first data connection is fulfilled, a request to the at least one access node to activate the at least one sidelink device for providing the second data connection.

Abstract: Apparatus and method for accelerating data handling in the protocol stack of a networked device. Embodiments of the disclosed invention may be used to increase the throughput rate of a networked device while offloading processing from the device's host processor. A method includes building a set of descriptors that describe the operations to be performed by a Protocol DMA Engine. A host processor builds the set of descriptors in lieu of performing the operations described by the descriptors. The set of descriptors is provided to the Protocol DMA Engine. The Protocol DMA Engine executes the operations described in the set of descriptors to produce a protocol layer output data unit from a protocol layer input data unit. The protocol layer output data unit is provided to a next layer of a network protocol stack.
