This document discloses a solution for adaptive transmission of data packets. According to an aspect, a method comprises: scheduling a first wireless interface of a user device to operate in a first transmission mode where the first wireless interface transmits payload data to a wireless network; scheduling a second wireless interface of the user device or another user device to operate in a second transmission mode where the second wireless interface transmits keep alive messages without payload data to the wireless network or to another wireless network; receiving at least one measured connection quality metric from the first wireless interface and from the second wireless interfaces; and rescheduling, on the basis of the received connection quality metrics, a transmission mode of at least one of the first wireless interface and the second wireless interface.
An apparatus comprising:
A method comprising:
A non-transitory computer readable medium comprising program instructions for causing an apparatus to perform at least the following:
Dependencies are inferred from the claim text.
From the US filing history. Foreign family members aren’t listed.
Wireless traffic scheduling: for collaboration of different radio technologies
Based on quality criteria: using measured or perceived quality
Arrangements for allocating sub-channels of the transmission path: allocation of payload; Allocation of data channels, e.g. PDSCH or PUSCH
Terminal devices: adapted for operation in multiple networks or having at least two operational modes, e.g. multi-mode terminals

Various embodiments relate to a multi-radio concept where a device has multiple wireless interfaces to transmit a data stream.
Some applications executed in a wireless device such as a smart phone require reliable, high-throughput connectivity. Live video streaming is one use case where continued and uninterrupted service availability often needs to be guaranteed. This is especially true for professional use, e.g. live streaming for commercial broadcasting, but there is also a large and increasing number of semi-professional users who generate live streaming content on platforms such as YouTube®, Facebook®, Twitch®, etc. Even a temporary disruption in the service availability may cause degradation of a quality of service or loss of video content.
According to an aspect, there is provided subject matter of independent claims. Dependent claims define some embodiments.
Some embodiments will now be described with reference to the accompanying drawings, in which
FIG. 1 illustrates a wireless communication system to which embodiments of the invention may be applied;
FIG. 2 illustrates a flow diagram of an embodiment for performing selective transmissions in an apparatus;
The following embodiments are only examples. Although the specification may refer to “an” embodiment in several locations, this does not necessarily mean that each such reference is to the same embodiment(s), or that the feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments. Furthermore, words “comprising” and “including” should be understood as not limiting the described embodiments to consist of only those features that have been mentioned and such embodiments may contain also features/structures that have not been specifically mentioned.
Reference numbers, both in the description of the embodiments and in the claims, serve to illustrate the embodiments with reference to the drawings, without limiting it to these examples only.
FIG. 1 depicts examples of simplified system architectures only showing some elements and functional entities, all being logical units, whose implementation may differ from what is shown. The connections shown in FIG. 1 are logical connections; the actual physical connections may be different. It is apparent to a person skilled in the art that the system typically comprises also other functions and structures than those shown in FIG. 1.
