Abstract: There is provided determining by an apparatus an access slot for communications on a first radio interface of a first and second radio interfaces. The first radio interface receives a first frame comprising at least one time related parameter for determining an access slot for communications on the first radio interface. After receiving the first frame, the apparatus is transitioned to a first operation mode, where the first radio interface radio interface is disabled. An access slot on the first radio interface may be determined based on the at least one time related parameter received before the first radio interface was disabled and based on the reception time of the frame on the second interface. In response to receiving a second frame on the second radio interface, the apparatus is transitioned to a second operational mode, where the first radio interface is enabled for transmission in the determined access slot.

Abstract: According to an example aspect of the present invention, there is provided a method, comprising: transmitting a request frame, from a first wireless device to a second wireless device, the request frame indicating a at least one requested transmission window for receiving a wake-up frame via a wake-up radio, and receiving, by the first wireless device from the second wireless device, the wake-up frame via the wake-up radio during at least one allocated transmission window, wherein the at least one allocated transmission window is based on the at least one requested transmission window.

Abstract: This document discloses a solution for using a proxy for a service to improve power-efficiency. According to an aspect, a method comprises: offloading, by a wireless device configured to provide a service, at least one function of the service to a proxy apparatus by using a main radio interface of the wireless device; indicating, by the wireless device to the proxy apparatus in connection with said offloading, that the wireless device shall enter a power-save mode where the wireless device disables the main radio interface and enables a wake-up radio interface of the wireless device; receiving, by the wireless device while in the power-save mode, a wake-up frame through the wake-up radio interface and, as a response to the reception of the wake-up frame, enabling the main radio interface; and after enabling the main radio interface, receiving by the wireless device a message from a subscriber device that subscribes to the service.

Abstract: Method, apparatus, and computer program product embodiments of the invention are disclosed to improve the discovery of wireless networks. In example embodiments of the invention, a method comprises: transmitting a wireless message including at least one condition for response from one or more wireless devices, the condition for response including at least one of receive power of the wireless message at the one or more wireless devices, service level of the one or more wireless devices, or identity of the one or more wireless devices that can respond with a selected response; and receiving one or more responses from the one or more wireless devices that can satisfy the at least one condition.

Abstract: This document discloses methods, apparatuses, and computer programs for operating a wireless apparatus during a service period between two wireless apparatuses. The service period comprises a first period during which only one of the apparatuses may terminate the service period and another period during which the other apparatus may terminate the service period.

Abstract: There is provided a solution in which a wireless node is caused to configure a plurality of transport layer protocol streams for a communication with another node via at least one communication path, wherein each transport layer protocol stream has a different maximum segment size; monitor at least one performance parameter of each communication path between the wireless node and the other node; and select at least one transport layer protocol stream for the communication on the basis of the monitoring.

Abstract: Rescue handovers of user equipment, for example, may be accomplished by a method that includes detecting that a downlink radio link cannot be reliably received. The method can also include initiating sending a report that the downlink radio link cannot be reliably received when the detecting indicates that the downlink radio link cannot be reliably received. The method can further include initiating performing a handover upon obtaining handover instructions responsive to the report.
