Abstract: The invention relates to detecting and indicating that a QoS estimate for a radio link serving an application does not fulfill a QoS requirement associated with the application. A client device monitors QoS estimates for a radio link serving an application in the physical layer. The monitoring is based on a QoS monitoring configuration associated with the application. Upon detecting that a QoS estimate does not fulfill a QoS requirement obtained from the QoS monitoring configuration, the client device provides a first indication to a second layer arranged above the physical layer. The first indication provides an early warning that the radio link does not fulfill the QoS requirement. Thereby, allowing the client device to take precautionary actions to counteract possible negative consequences of the non-fulfillment of the QoS requirement. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: The invention relates to a processing device (200) for a client device (100), the processing device (200) obtains a set of reference signal configurations for a set of serving downlink beams (502a, 502b, . . . , 502n), wherein each reference signal configuration of the set of reference signal configurations is associated with a respective serving downlink beam of the set of serving downlink beams (502a, 502b, . . . , 502n), and wherein each reference signal configuration of the set of reference signal configurations comprises a reference signal periodicity. The processing device (200) further performs beam monitoring on the set of serving downlink beams (502a, 502b, . . . , 502n) based on the reference signal periodicities of the set of reference signal configurations. Furthermore, the invention also relates to a client device (100) comprising the processing device (200), corresponding methods, and a computer program.

Abstract: The disclosure relates to early detection and indication of a Quality-of-Service (QoS) non-fulfillment in one or more radio links serving an application. A client device monitors for a QoS non-fulfillment in the one or more radio links based on a QoS monitoring configuration associated with the application. The QoS monitoring configuration may be received from a network node and/or derived based on a predefined rule. Upon detection of a QoS non-fulfillment of one or more QoS requirements obtained from the QoS monitoring configuration, the client device provides a QoS non-fulfillment indication to the application. The QoS non-fulfillment indication gives the application an early warning about QoS non-fulfillment on the one or more radio links. Thereby, allowing the application to take precautionary actions to counteract possible negative consequences of the QoS non-fulfillment. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: The present disclosure relates to client devices and methods for link failure recovery in discontinuous reception (DRX) in connected mode (C-DRX). One example client device is configured to perform beam/link monitoring according to a link recovery procedure if the client device is in a C-DRX mode operation with a network access node, where a configured beam failure detection (BFD) timer of the link recovery procedure is a function of a periodicity of beam failure indications.

Abstract: The disclosure relates to performing phase compensation at a transmitter. A processing device for a network access node generates a phase compensated modulation symbol based on at least one first modulation symbol and at least on one of a frequency offset parameter and a time offset parameter. The frequency offset parameter may be determined based on an offset between a reference frequency f0 and a DC (0 Hz) frequency such that the frequency offset parameter corresponds to the reference frequency f0. Also, the reference frequency f0 can be at least partly based on the carrier of up-conversion frequency used by the processing device and the reference frequency f0 can be the carrier for up-conversion frequency. The phase compensated symbol is transmitted to a receiver, such as a client device. Furthermore, the disclosure also relates to corresponding methods and a computer program.
