  • Beam-Scan Time Indicator
    Publication number: 20240040524
    Abstract: The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

  • Method and apparatus for triggering of specific operation mode for terminals operating in extended long range
    Patent number: 11856648
    Abstract: Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

  • Retransmission protocol feedback handling with multiple feedback times
    Patent number: 11750337
    Abstract: In a mobile network, the transmission of downlink data blocks to one or more terminal devices is accomplished on the basis of a retransmission protocol with a first feedback time defining a time interval between transmission of a first data block and transmission of a first feedback message being different from a second feedback time defining a time interval between transmission of a second data block and transmission of a second feedback message. The first feedback message indicates whether the first data block was successfully received, and the second feedback message indicates whether the second data block was successfully received. A base station of the mobile network controls the terminal device to send the second feedback message on other resources than used for transmission of the first feedback message.
