摘要： There is provided mechanisms for calibrating radio frequency branches of a radio transceiver device in a radio access network node. A method is performed by a network node. The method comprises co-scheduling downlink time/frequency resources for terminal devices in accordance with a set of terminal device identifiers. 5 One of the terminal device identifiers is not of any terminal device served by the radio access network node. The downlink time/frequency resources for this terminal device identifier define time/frequency resources for calibrating the radio frequency branches. The method comprises determining a difference in amplitude/phase between the radio frequency branches by analysing a signal as received via an 10 internal coupler unit in the radio transceiver device. The signal represents the time/frequency resources as transmitted over at least some of the radio frequency branches. The method comprises calibrating the radio frequency branches by adjusting an amplitude/phase setting of at least one of the radio frequency branches according to the determined difference. 15 (Fig. 3)

摘要： The present disclosure provides a method and a dual band receiver for handling an analog dual band radio signal comprising a first frequency band component and a second frequency band component. The method comprises sampling the analog dual band radio signal through the use of interleaving analog-to-digital converters, ADCs, to obtain four sampled signals including a first I component, Iin + , a first Q component, Qin + , a second I component, Iin - , and a second Q component, Qin - , wherein phases of Qin +, Iin - and Qin - are respectively offset with respect to phases of Iin +, Qin + and Iin - by π/2. Then, the four sampled signals are filtered through the use of polyphase filters to obtain a first set of filtered signals (a1, a2, a3, a4) each of which has a same power as the first frequency band component and a second set of filtered signals (b1, b2, b3, b4) each of which has a same power as the second frequency band component. Subsequently, a power of the first frequency band component, a power of the second frequency band component and a total power of the first frequency band component and the second frequency band component are estimated, based on the four sampled signals, the first set of filtered signals and the second set of filtered signals. Next, the first frequency band component and the second frequency band component are selectively attenuated based on the estimated powers.

摘要： A method of small data transmission (SDT) and related wireless device are described. The method comprises obtaining information at a first time about one or more pre-configured SDT resources including a timing advance (TA) value. A validity of a first measurement of the serving cell is determined by determining whether it was obtained within a first time range based on the first time and on a first set of one or more 5G New Radio (NR) parameters. A validity of a second measurement of the serving cell is determined by determining whether it was obtained within a second time range based on a second time (start time of next SDT occasion), and on a second set of one or more 5G NR parameters. The method further comprises validating the TA when the first and second measurements are valid, and performing a SDT uplink transmission using the validated TA.
