    Abstract: This document discloses a solution where power management of devices of a wireless networks are controlled in connection with an absence period. According to an aspect, an apparatus determines at least one allowable power management mode for at least a second apparatus; causes transmission of a first frame indicating the at least one allowable power management mode; and causes transmission of an indication of an absence period during which it is not possible to transfer frames with the apparatus, wherein the indication is provided in at least one of the first frame and a second frame. The first frame configures at least the second apparatus to be ready to communicate with the apparatus at the end of the absence period in a case where the at least one allowable power management mode indicates a first power management mode.

    Abstract: There is provided, for example, a method, comprising: transmitting, by a wireless device, a data accumulation request to an access node of a wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data; receiving a message from the access node, wherein the message indicates that there is downlink data in the access node for the wireless device; and triggering a service period for receiving the downlink data from the access node upon determining, on the basis of the received message, that the downlink data satisfies the at least one downlink accumulation rule.

    Abstract: A node configured to support a method of communicating between two nodes in the unlicensed spectrum is disclosed where a channel can be simultaneously used for downlink and uplink communication. The method performed at a node involves assessing at that node, for example, a UE, that there is a transmission to be made to a further node, for example a gNB. The first node receives an indication that communication with the further node is supportable on a channel within an unlicensed spectrum using flexible frequency division duplex (FDD) techniques. The first node determines whether transmission by the further node is being made within a first portion of the channel within the unlicensed spectrum; and if so, transmits to the further node within a second portion of the channel which does not overlap with the first.

    Abstract: Disclosed is an apparatus, computer program product, and method for determining to transmit frames on a frequency channel; determining a first sub-band of the frequency channel for wake-up radio transmissions according to a wake-up radio access technology and a second sub-band of the frequency channel, different from the first sub-band, for main radio transmissions according to another radio access technology; allocating the first sub-band for the wake-up radio transmissions and simultaneously allocating the second sub-band for the main radio transmissions; transmitting, using a main radio interface of an access network (AN), using said another radio access technology, a frame comprising a header indicating said allocations, and transmitting, after transmitting the header, a wake-up signal on the first sub-band by using a wake-up radio interface of the AN operating according to the wake-up radio access technology and, simultaneously, transmitting another radio signal on the second sub-band using the main radio interface.

    Abstract: According to an example aspect of the present invention, there is provided a method, comprising: establishing, via a main radio, a data link schedule comprising a plurality of communication resource periods for a data link between a first wireless device and a second wireless device, wherein at least a sub-set of the plurality of communication resource periods are scheduled to start periodically, pausing data transmission by transferring, via the main radio, a control message during a communication resource period of the data link schedule, entering the power save mode in response to transferring the control message, maintaining the power save mode over at least one further communication resource period of the data link schedule, and transmitting a wake-up frame, via a wake-up radio different from the main radio, in response to detecting need for further data transmission during the data link schedule.
