The first electronic device also generating an SDP offer comprising media descriptions for at least one media stream based on the acquired media capabilities. At least one media stream in the SDP offer is represented by at least two media descriptions. The at least two media descriptions represent asymmetric media capabilities in relation to each other. A first SDP message comprising the generated SDP offer is sent to a second electronic device.

2. WO/2015/053670 ENABLING MITIGATION OF INTERFERENCE BETWEEN AN EXTERNAL WIRELESS SYSTEM AND A MOBILE COMMUNICATION SYSTEMWO16.04.2015
H04W 24/04
PCT/SE2013/051189TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)TERCERO VARGAS, Miurel Isabel
The proposed technology relates to methods, devices and network nodes for enabling mitigation of interference between an External Wireless System, EWS, and a mobile communication system. For example, a UE may detect (S1) an EWS event involving EWS operation interfering with the operation of the mobile communication system provided at least one interference condition is fulfilled. The interference condition(s) includes a first condition based on a frequency relation between a representation of an operating frequency of the EWS and a representation of a reference frequency. The UE may then enable (S2) the mitigation of interference based on event information representing the EWS event.

3. WO/2015/053664 CONGESTION CONTROL IN A TRANSPORT NETWORKWO16.04.2015
H04W 28/02
PCT/SE2013/051172TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)NÁDAS, Szilveszter
A congestion control method of a cellular communication system is disclosed. A first protocol data unit having a first sequence number is transmitted from a radio network controller to a base station via a transport network. The base station detects a congestion situation of the transport network by detecting loss of the first protocol data unit during transmission over the transport network.In response to detecting the congestion situation,a notification message indicative of the detected congestion situation is transmitted from the base station to the radio network controller via the interface of the transport network. In response to receiving the notification message, the radio link controller of the radio network controller creates a second protocol data unit, which is empty to indicate the congestion situation to a TCP of the wireless communication device. The second protocol data unit is transmitted from the radio network controller to the base station via the interface of the transport network and from the base station to the wireless communication device via an air interface of the radio link. When the second protocol data unit is received by the wireless communication device, detection of the congestion situation is triggered by the TCP of the wireless communication device based on decoding of the second protocol data unit, and a congestion avoidance mode of the TCP is entered. Corresponding method and arrangement of a radio network controller are also disclosed as well as corresponding computer program product, radio network controller, and cellular communication system.

4. WO/2015/053666 POWER SAW CHAIN TENSIONING ARRANGEMENTWO16.04.2015

PCT/SE2013/051175HUSQVARNA ABKISTLER, Michael
The present invention in particular relates to a power saw chain tensioning arrangement for tensioning and releasing a power saw chain (6) by lengthwise displacement of a chain guide bar (2) supporting the saw chain (6). It is proposed that thread of a rod type threaded linear actuator (11) of the tensioning arrangement during displacement of the guide bar (2) directly meshes a complementary linear threaded structure (12) of the guide bar (2) such that rotation of the linear actuator (11) on its own axis results in a displacement between the linear actuator (11) and the linear threaded structure (12). The complementary linear threaded structure (12) is implemented directly on the guide bar (2).

H04B 1/54
PCT/SE2013/051184TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)LI, Ming
Method and transceiver arrangements for reducing a leakage signal's impact on a receiver part 320 of the transceiver arrangement 300.The leakage signal originates from a transmitter part 310 of the transceiver arrangement 300. The radio base station is adapted to communicate in a Time Division Duplex, TDD mode in a cellular network. The method comprises frequency shifting 402, by the transmitter part 310, a downlink, DL, baseband by an offset frequency, fc, the DL baseband comprising DL data. Furthermore, the method comprises to mixing 404, by the transmitter part (310), the frequency shifted DL baseband with a Transmitter Local Oscillator, TX LO, frequency, fLO to produce a DL signal spectrum. The offset frequency, fc, and the TX LO frequency fLO is selected such that fLO = fDL - fc, or fLO = fDL + fc where fDL is the center frequency of the DL signal spectrum, such that the TX LO leakage signal reaching 408 the receiver part 320 is located outside, or on an edge of, a UL signal spectrum when received by the receiver part 320. By frequency shifting an output frequency of a transmitter local oscillator with an offset frequency, and frequency shifting a transmitter baseband with the offset frequency, but in a reverse direction, leakage signals originating from the transmitter local oscillator may be prevented from affecting a receiver RF spectrum, without affecting the transmitter RF spectrum.
