Abstract: A method for a radio access node configured for transmission to a user device over multiple links. The method includes, responsive to data being available for transmission to the user device, determining which of the multiple links are possible links for transmission of the data, selecting one or more links of the possible links, and transmitting a wake-up signal to the user device, wherein the wake-up signal is indicative of the selected one or more links. A method is also disclosed for a user device configured for reception from a radio access node over multiple links. The method includes receiving a wake-up signal from the radio access node, wherein the wake-up signal is indicative of one or more of the multiple links, and waking up one or more of the multiple receivers, corresponding to the indicated one or more links.

Abstract: A wireless communication device is operated to transmit information on a random access channel of a network node. Operation involves determining a first transmit power level for a transmission of the information, and selecting a first transmission time for the transmission of the information, wherein the selected first transmission time is determined by a number drawn from a first contention window, and wherein the selected first transmission time corresponds to a first amount of time delay that must elapse before transmission of the information occurs. The information is transmitted at the selected first transmission time, at the first transmit power level. When the transmitted information was not successfully received by the network node, a size of a second contention window is determined based on a size of the first contention window and on the first transmit power level.

Abstract: A wireless communication device (11) maintains, on a first channel, a radio link to a further wireless communication device (10). The wireless communication device (11) sends, to the further wireless communication device (11), an indication that the wireless communication device supports multi-link operation. Further, the wireless communication device (11) receives a request from the further wireless communication device (10). In response to the request, the wireless communication device (11) utilizes the multi-link operation to perform at least one measurement on a second channel while maintaining the radio link to the further wireless communication device (10). Further, the wireless communication device (11) sends, to the further wireless communication device, one or more measurement reports representing the at least one measurement.

Abstract: Method for controlling a pump station including a pump well for accommodating liquid and at least one pump located in the pump well for pumping liquid from the pump well, the at least one pump having an inactive state and an active state, respectively. The method includes initiating a pump cycle having a predetermined pump cycle length, bringing the at least one pump to the active state, registering a pump start time of a pumping duration time interval, and calculating a pump stop time for the pumping duration time interval to occur when the quantity of liquid pumped during the pumping duration time interval, as calculated from a predetermined pump capacity of the pump, is greater than or equal to a calculated liquid inflow to the pump well during the present pump cycle. The at least one pump enters said inactive state when the pumping duration time interval has elapsed.
