Information specifying that component carriers or reference signals cross component carriers are spatially quasi co-located, or information about a SQCL group including spatially quasi co-located carriers, may be transmitted to a UE, e.g., using broadcast signaling, radio resource control (RRC) signaling, a media access control-control element (MAC-CE), downlink control information (DCI) signaling, or a combination thereof.Type: GrantFiled: February 16, 2021Date of Patent: March 21, 2023Assignee: Futurewei Technologies, Inc.Inventors: Bin Liu, Pengfei Xia

Patent number: 11601175Abstract: Methods, devices and computer programs for determining new transmit directions to use for beamformed transmissions in case the link quality of an existing direction falters. A transmitting communication device and a receiving communication device cooperate via a beam tracking procedure to determine a new suitable transmit direction to use for upcoming beamformed transmissions. Information relating to the beam tracking procedure is communicated over an existing link that enables communication between the transmitting and receiving communication devices. The receiving communication device provides the transmitting communication device with information about a beam scan performed in order to detect tracking beams transmitted by the transmitting communication device. This information allows the transmitting communication device to determine suitable transmit directions to use.Type: GrantFiled: October 14, 2021Date of Patent: March 7, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Torbjörn Wigren, Oskar Mauritz

Patent number: 11601172Abstract: A technique is provided for controlling a beam pattern employed by an antenna apparatus. The antenna apparatus comprises an antenna array, and beamforming circuitry to employ a beam pattern in order to generate a beam using the antenna array to facilitate wireless communication with at least one further antenna apparatus. Beam pattern adjustment circuitry is then arranged to receive a control signal indicative of a motion being imparted to the antenna apparatus, and to adjust the beam pattern to be used by the beamforming circuitry in dependence on the control signal, so as to alter a width of the beam in order to mitigate variation in link quality of the wireless communication due to the motion.Type: GrantFiled: October 14, 2020Date of Patent: March 7, 2023Assignee: AIRSFAN IP HOLDCO LLCInventors: Andrew Logothetis, Marlon Peter Persaud

Patent number: 11595906Abstract: A wireless device receives: a first maximum total transmit power allowed for a first cell group of a first type of radio access technology; and a second maximum total transmit power allowed for a second cell group of a second type of radio access technology. It is determined that a total transmission power exceeds a value based on: a first power for transmission of first uplink signal(s) via the first cell group, and a second power for transmission of second uplink signal(s) via the second cell group. The first and second powers are less than or equal to the first and second maximum total transmit powers respectively. Scheduled transmission of the first uplink signal(s) of the first cell group is dropped in response to the first cell group being of the first type of radio access technology. Second uplink signal(s) are transmitted to a base station.Type: GrantFiled: January 9, 2020Date of Patent: February 28, 2023Assignee: Ofinno, LLCInventor: Esmael Hejazi Dinan
