  • Publication number: 20220167403
    Abstract: Disclosed is a latency control method of a transmitter apparatus adapted for transmission of a plurality of packets under clear channel assessment requirements and latency requirements. The method comprises determining a maximum required time for clear channel assessment for the plurality of packets and determining a duration of time related to the determined maximum required time. For example, the duration of time may be determined as being equal to the determined maximum required time for clear channel assessment plus an offset. The offset may be equal to zero, or may be equal to a positive value. In some embodiments, the offset may be equal to, or larger than, a duration of another packet (which is not comprised in the plurality of packets). The method also comprises enforcing, for each packet of the plurality of packets, the determined duration of time to elapse after completion of transmission of the packet, before transmission of a subsequent packet of the plurality of packets is initiated.

  • Patent number: 10687244
    Abstract: A first transmit device (200), a relay device (202) and methods therein, for supporting wireless communication between transmit devices over a shared radio resource in a wireless network. The first transmit device (200) records (2:1B) source identities and destination identities of detected transmissions of data made by other transmit devices (204). When an own transmission of data is performed, the first transmit device (200) appends (2:2A) a report indicating the source identity and the destination identity of each detected transmission of data. By receiving (2:2B) transmissions of data with such appended reports from various transmit devices (200, 204), the relay device (202) is able to identify (2:3) two transmit devices (204A, 204B) that are not able to communicate directly with each other, and to forward (2:5) any transmission(s) (2:4) of data between the two identified transmit devices.

  • Patent number: 10425975
    Abstract: A controller controls a communications link between a first node and a second node, by requesting one or more candidate devices to detect signals transmitted by the first and second nodes. It receives signal quality measurements from at least one candidate device, relating to signals received by each respective candidate device from the first and second nodes and, in response to the received signal quality measurements, determines whether to select a candidate device to act as a relay between the first and second nodes. If this determination is made, it requests the selected candidate device to act as a relay between the first and second nodes. A candidate device receives the request from the controller and determines a signal quality measurement of signals received from the first and second nodes. It reports the signal quality measurements of signals received from the first and second nodes to the controller device.

  • Patent number: 9894697
    Abstract: The present disclosure relates a method, performed by a communication node of a cellular radio access network, for estimating a radio link quality of a direct link between a first user equipment and a second user equipment. The invention also provides a method performed in a user equipment, which method is used to monitor communication for the purpose of estimating communication in a possible direct link between a first user equipment and a second user equipment. The communication node instructs a user equipment to eavesdrop an uplink of an other user equipment UL1. The communication node obtaining data directly from the uplink UL1 and receives eavesdropped data from the user equipment. The communication node evaluates the radio link based on the data obtained from the uplink and the data eavesdropped from the uplink. The user equipment receives an instruction to eavesdrop the uplink UL1. The user equipment receives and obtains digital data from the uplink UL1, and reports to the network.

  • Patent number: 9713160
    Abstract: The invention relates to a method for allocating a common radio resource for simultaneous transmission of data streams in multiple pairs of communication nodes in a multi-node wireless network. The invention also relates to a method of assessing radio resource isolation in a multi-node wireless network. The inventive methods include transmission (44) of at least a first and a second test probe message on a common radio test resource. Receipt of the intended test probe messages are verified (45), whereupon radio resource isolation may be determined and a common radio resource allocated (46) for transmission in the tested communication node pairs. The invention also relates to a communication node and a control node wherein the inventive methods are applied.

  • Patent number: 9699795
    Abstract: Methods and apparatuses are provided for mitigating interference in a Wireless Local Access Network or WLAN that may be caused by a radio node. Signal measurements are monitored at frequencies corresponding to one or more WLAN channels in one or more frequency bands. It is determined, based on the signal measurements at the frequencies, whether there are any channels among possible primary and secondary channel pairings of the WLAN channels that are being used by the WLAN as secondary channels. Spectrum usage by the radio node is controlled in dependence on the determination.
