  • Publication number: 20200322093
    Abstract: This application provides a client device, a method, and a computer program. The client device obtains a first parameter associated with a radio link failure timer. The first parameter indicates a first time period during which the radio link failure timer is reset and thereafter started. The client device further obtains a second parameter associated with the radio link failure timer. The second parameter indicates a second time period during which the radio link failure timer is started and thereafter reset. Based on the first parameter and the second parameter, the client device determines a value of the radio link failure timer.

    Abstract: Methods, a user node and a network node are provided. The user node is configured to determine an indication of at least one wake-up latency of the user node, the at least one wake-up latency being a time period for the user node to wake-up and start to monitor a downlink channel transmitted by the network node of a wireless communication network; determine a message comprising the indication; and transmit the message to the network node. The network node is configured to receive from the user node a message, and set a wake-up offset for the user node based on the at least one wake-up latency comprised in the message, the wake-up offset being a time period between a wake-up signal transmission and a subsequent downlink channel transmission from the network node to the user node.

  • Patent number: 10454628
    Abstract: A transmitter, a receiver and a method for communicating data packets. The method comprises receiving a data packet and determining if it is a re- or new transmission; and, when it is a retransmission: combining the received data packet with oldest unsuccessfully decoded data packet stored in a second memory, and decoding the combined data packet; when it is a new transmission: decoding the received data packet; checking if the decoding is successful; deleting the oldest stored data packet in the first memory; storing the decoded data packet in the first memory when the decoding is successful or storing the decoded data packet in the second memory when the decoding is not successful; and transmitting feed-back information to the transmitter.

  • Publication number: 20190289481
    Abstract: A network node and a client device are described. The network node comprises a processor configured to determine a test initiation message, wherein the test initiation message indicates a set of client device identities corresponding to a set of client devices participating in a radio configuration test, a number of test packets in a sequence of test packets, and a transmission direction. The transmission direction is at least one of the group consisting of: a first transmission direction from the network node to the set of client devices and a second transmission direction from the set of client devices to the network node. A transceiver is configured to transmit the test initiation message to the set of client devices, and thereafter the transceiver either transmits or receives the sequence of test packets based on the at least one transmission direction. The transceiver also receives at least one feedback message from each client device.
