Patent number: 11109195Abstract: 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.Type: GrantFiled: September 25, 2019Date of Patent: August 31, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: George Koudouridis, Henrik Lundqvist, Xavier Gelabert

Patent number: 10652878Abstract: 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.Type: GrantFiled: October 4, 2018Date of Patent: May 12, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Mario Costa, Petteri Kela, Xavier Gelabert

Patent number: 10524196Abstract: 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.Type: GrantFiled: October 12, 2017Date of Patent: December 31, 2019Assignee: Huawei Technologies Co., Ltd.Inventors: Xavier Gelabert, Yinggang Du, George Koudouridis, Andrey Krendzel

Patent number: 10412756Abstract: 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.Type: GrantFiled: September 1, 2017Date of Patent: September 10, 2019Assignee: Huawei Technologies Co., Ltd.Inventors: Xavier Gelabert, Henrik Lundqvist, Mario Costa, Petteri Kela

Patent number: 10362625Abstract: 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.Type: GrantFiled: September 12, 2017Date of Patent: July 23, 2019Assignee: Huawei Technologies Co., Ltd.Inventors: Petteri Kela, Mario Costa, Henrik Lundqvist, Xavier Gelabert
