  • Patent number: 10771210
    Abstract: An Access Node (ANd), for allocating a beacon resource pattern to a User Node (UNd), is configured to: detect the UNd by receiving an uplink beacon signal from the UNd; allocate a beacon resource pattern from a predetermined set of beacon resource patterns to the detected UNd; and signal information about the allocated beacon resource pattern to the UNd.

  • Patent number: 10652878
    Abstract: An access node in a wireless communication system includes a transceiver configured to receive one or more uplink pilots associated with a user node via a radio link, and a processor configured to determine, based on the one or more uplink pilots, a location of the user node and whether the radio link is a line of sight radio link or a non-line of sight radio link. When the radio link is a line of sight radio link, the processor determines a position based precoding vector based on the location of the user node, and generates a precoded downlink control signal based on the determined position based precoding vector. The transceiver transmits the precoded downlink control signal to the user node.

  • Publication number: 20200021952
    Abstract: The invention relates to devices in a wireless network transmitting uplink beacons such as a network node comprising a transceiver for communication with at least one User Equipment, UE. The network node is configured to receive an at least one uplink beacon corresponding to the at least one UE, and to determine a group comprising at least a first UE and a second UE, based on received uplink beacons from the first UE and the second UE. The network node is also configured to determine uplink beacon reconfiguration for each UE in the group, comprising information specifying a group uplink beacon, and information specifying a UE configuration for the UEs of the group, indicating each UE of the group either as being a UE for sending said group uplink beacon, or as a UE for receiving said group uplink beacon.

  • Patent number: 10524196
    Abstract: A first Control Node (CNd) and a method therein, for selecting a serving CNd for a User Node (UNd) by communication with at least a second CNd. The first CNd is configured to receive an uplink beacon measurement report comprising at least one measurement of an UNd uplink beacon, from at least one Access Node (ANd) controlled by the first CNd. The first CNd is further configured to preliminarily select a serving CNd for the UNd, based on the received uplink beacon measurement report concerning the UNd; confirm the preliminarily selected serving CNd by communication with the second CNd; and, select serving CNd for the UNd when the preliminarily selected serving CNd is confirmed by the second CNd.

  • Patent number: 10412756
    Abstract: Implementations described herein relate generally to a user device, to an access node, and to methods for a user device and for an access node. The user device includes a receiver configured to receive at least one downlink signal from an access node. The user device further includes a processor configured to measure the at least one downlink signal at two time instants, to determine if a difference of the measured at least one downlink signal at the two time instants exceeds a threshold, and to generate, when the difference exceeds the threshold, at least one uplink transmission. The user device further includes a transmitter configured to transmit the at least one uplink transmission over an uplink random access channel.

  • Patent number: 10362625
    Abstract: Implementations describe a user equipment, an access node, and to methods for a user equipment and for an access node. The user equipment includes a receiver configured to receive a downlink control signal (CTRLS) over a downlink control channel (PDCCH) from an access node. The user device also includes a processor configured to, when the user equipment is in a Radio Resource Control (RRC) connected mode, switch on the receiver at a time point (tstart_symbol) when a symbol comprising the downlink control signal (CTRLS) starts in time domain. The processor is further configured to switch off the receiver at a time point (tend_symbol) when the symbol comprising the downlink control channel (CTRLS) ends in time domain.

  • Publication number: 20180092040
    Abstract: The present invention relates to a user device and a network node. The user device (100) comprises a processor (102), and a transceiver (104); wherein the processor (102) is configured to: operate the transceiver (104) in a first mode of operation (M1) in which the transceiver (104) is configured to receive Radio Frequency, RF, signals and to transmit RF signals; or operate the transceiver (104) in a second mode of operation (M2) in which the transceiver (104) is configured to transmit RF signals and not to receive RF signals.
