Abstract: There is provided generating, at a cell configured for a first air interface protocol, a reference signal based on a cell identifier for a second air interface protocol. At the cell configured for the first air interface protocol it is determined an air interface resource allocation for the first air interface protocol based on the cell identifier for the second air interface protocol. The cell configured for the first air interface protocol transmits the generated reference signal according to the determined air interface resource allocation.

Abstract: A UE receives configuration for interference mitigation pattern(s) indicating which resource elements in a time-frequency resource space should be measured. The UE performs interference measurements based on the received one or more interference mitigation patterns. A network node determines configuration for interference mitigation pattern(s0 indicating which resource elements in a time-frequency resource space should be measured by a user equipment. The network node sends, toward the user equipment, the configuration for use by the user equipment to perform interference measurements of the one or more interference mitigation patterns.

Abstract: An apparatus such as a user equipment configured to support an irregular bandwidth signal. The apparatus comprising multiple means for frequency translating a wireless communication signal in a frequency bandwidth that is different to a predefined bandwidth and for filtering said frequency translated wireless communication signals. Means for adjusting a centre frequency used by the multiple means for frequency translating; and control means.

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 method performed at a node where in response to receipt of a signal in a channel in the unlicensed spectrum, the node initiates a scan on one of the channels in the unlicensed spectrum to determine whether the channel is available for transmitting a response. If it is available, then a response is transmitted that comprises information regarding the quality of the channel and the quality of other channels in the unlicensed spectrum along with an indication as to whether the signal was successfully received and decoded. The method performed at the transmitting node is also disclosed, along with the transmitting and receiving nodes and a computer program for performing the methods.

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: According to an aspect, there is provided a controller of a pool of terminal devices comprising means for performing the following. Initially, information on requirements of data traffic to be handled by the pool of terminal devices and data traffic statistics for the pool are maintained in a memory of the controller. Upon receiving results of scanning of available radio access networks and capabilities from one or more primary terminal devices, the controller analyzes the results of the scanning, the requirements of the data traffic and the data traffic statistics to determine optimal radio access configurations for the pool of terminal devices for satisfying the requirements of the data traffic. Then, the controller configures the pool of terminal devices for providing radio access according to the optimal radio access configurations. Finally, the controller provides radio access using the pool of terminal devices according to the optimal radio access configurations.
