  • License assisted listen-before-talk
    Patent number: 10455559
    Abstract: Systems and methods are disclosed herein that relate to the use of signals in a licensed spectrum to assist with determining a status of an unlicensed channel(s) in an unlicensed spectrum. In some embodiments, a method of operation of a wireless device in a wireless system in which the wireless device transmits and/or receives in both a licensed spectrum and an unlicensed spectrum comprises attempting to detect a busy indication transmitted in the licensed spectrum. The busy indication is an indication that another wireless device is transmitting in the unlicensed spectrum. The method further comprises determining whether to transmit in the unlicensed spectrum based on whether the wireless device has detected a busy indication transmitted in the licensed spectrum. By using signals in the licensed spectrum, the hidden node problem and/or the exposed node problem in the unlicensed spectrum can be mitigated.

  • Method and apparatus for cooperative positioning in a wireless communication network
    Patent number: 10440552
    Abstract: According to the teachings herein, a wireless device that is a candidate for operating in the cooperative positioning advantageously activates that mode in response to detecting a warning situation. In some embodiments, the detection and/or activation operations are autonomously undertaken by the wireless device. In other embodiments, the wireless communication network provides warning situation detection and/or control of the cooperative positioning mode. More generally, the wireless communication network maintains a database identifying those wireless devices within a given service area that are cooperative positioning mode candidates—e.g., the devices having D2D communication capability and operational configurations that allow such operation. By the network providing such information in advance of a warning situation, the candidate devices have the information needed to efficiently discover or otherwise identify other such candidates.

  • Method for enabling a base station to decode data received from a first wireless device using a network coded form of the data received from a second wireless device
    Patent number: 10432383
    Abstract: A method and a base station are provided. The base station obtains a first path gain of a cellular radio link to a first wireless device, a second path gain of a cellular radio link to a second wireless device and a third path gain of a Device-to-Device radio link between the first wireless device and the second wireless device. When the first, second and third path gains satisfy a threshold condition, the base station instructs the second wireless device to apply network coding on first data transmitted from the first wireless device and to transmit a network coded form of the first data. The base station receives a radio signal with the first data transmitted from the first wireless device and uses the network coded form of the first data transmitted by the second wireless device for decoding the first data.

  • Bidirectional full duplex aware detection of transmission activity
    Patent number: 10420146
    Abstract: A radio device (10) configures a full duplex radio link from the radio device (10) to a further radio device (100). The full duplex radio link supports simultaneous bidirectional transmission on a carrier frequency. Further, the radio device (10) detects transmission activity on the carrier frequency. The radio device (10) determines whether the detected transmission activity is by the further radio device (100). Depending on whether the detected transmission activity is by the further radio device (100), the radio device (10) controls its own transmission activity on the carrier frequency.

  • Coordination Of Scheduled And Contention-Based Uplink Transmissions
    Publication number: 20190261387
    Abstract: A radio device (10) performs uplink transmissions on a first carrier (F1). The uplink transmissions on the first carrier require scheduling by a node (100) of a wireless communication network. Further, the radio device (10) performs uplink transmissions on a second carrier (F2). The uplink transmissions on the second carrier (F2) require that, by a carrier sense operation, the radio device (10) assesses the second carrier (F2) as being unoccupied before proceeding to the uplink transmission on the second carrier (F2). For a certain uplink transmission on the second carrier (F2), the radio device (10) performs the carrier sense operation to assess whether the second carrier (F2) is unoccupied and provides an indication of a result of the carrier sense operation to the node (100) which is responsible for the scheduling.

    Abstract: Systems and methods are disclosed herein that relate to the use of a Device-to-Device (D2D) sidelink, e.g., in a licensed spectrum, to assist with clear channel assessment in an unlicensed spectrum. In doing so, the hidden node problem and/or the exposed node problem can be mitigated. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises performing a sidelink-assisted clear channel assessment (SLA-CCA) procedure to determine whether to transmit on an unlicensed channel. The SLA-CCA procedure is a Clear Channel Assessment (CCA) procedure that is assisted by information received by the wireless device from one or more other wireless devices over a D2D sidelink in a licensed spectrum. The method further comprises, upon determining to transmit on the unlicensed channel as a result of performing the SLA-CCA procedure, transmitting a transmission on the unlicensed channel.

  • Method and radio access point for handling communication between wireless devices
    Patent number: 10237880
    Abstract: Method and radio access point for handling a two-way communication between a first wireless device and a second wireless device which are both served by the radio access point. A set of candidate transmission modes are available for use in the two-way communication. The radio access point obtains a mode-specific quality metric related to a predicted Signal to Interference and Noise Ratio, SINR, for each one of the candidate transmission modes, and selects one of the candidate transmission modes based on the obtained mode-specific quality metrics. The radio access point is thus able to select the transmission mode that has the best mode-specific quality metric in the set. The selected transmission mode is then applied for the two-way communication. Thereby, the most favorable transmission mode may be selected and used to provide satisfactory or even optimal performance.
