Patent number: 11665738Abstract: Disclosed is a method, device, apparatus for transmitting and receiving a request signal, comprising: a base station determines a channel occupancy request signal to be transmitted, the channel occupancy request signal being a request signal for requesting channel occupancy to a terminal after the base station executes a listen-before-talk operation on the direction corresponding to at least one beam; the base station schedules transmission of the channel occupancy request signal on a downlink control channel; the terminal detects the downlink control channel that schedules the transmission of the channel occupancy request signal; and the terminal receives the channel occupancy request signal according to a detection result. The use of the present invention overcomes a defect of the prior art that has no design for the channel occupancy request signal, and implements transmission of an eNB channel occupancy request signal.Type: GrantFiled: April 22, 2019Date of Patent: May 30, 2023Assignee: Datang Mobile Communications Equipment Co., Ltd.Inventors: Jiaqing Wang, Fang-Chen Cheng

Patent number: 11664961Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a guard period associated with switching from a first communication mode to a second communication mode. The UE may be operating in a half-duplex frequency division duplexing mode of operation. The guard period may be determined based at least in part on at least one of: a number of phased locked loops to be used for the first communication mode and the second communication mode, and a particular subcarrier spacing associated with the UE. The UE may switch from the first communication mode to the second communication mode based at least in part on the guard period. Numerous other aspects are provided.Type: GrantFiled: October 23, 2020Date of Patent: May 30, 2023Assignee: QUALCOMM IncorporatedInventors: Hung Dinh Ly, Peter Pui Lok Ang, Tingfang Ji

Patent number: 11658697Abstract: Embodiments for port reconfiguration for passive intermodulation interference mitigation are presented herein. A base station device comprises a signal processing component comprising a passive intermodulation interference component and an antenna configuration component. The passive intermodulation interference component determines passive intermodulation interference corresponding to uplink signals that have been received, via a configurable cellular antenna array of the base station device, from respective wireless devices of a group of wireless devices that have been communicatively coupled to the base station device. The antenna configuration component selects a defined configuration of a group of cellular antenna ports of the configurable cellular antenna array to facilitate a reduction of the passive intermodulation interference corresponding to the uplink signals.Type: GrantFiled: November 6, 2020Date of Patent: May 23, 2023Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T Mobility II LLCInventors: Ernest Tsui, Michael Taylor, Weihua Ye, Young Suh, Paul Maxwell, Guanying Ru, James Hollister

Patent number: 11652675Abstract: Embodiments disclosed herein relate to reducing or substantially eliminating an insertion loss caused by isolating a transmit circuit from a receive circuit of an electronic device. To do so, an isolation circuit may be disposed between the transmit circuit and the receive circuit. The isolation circuit may have a first signal path and a second signal path. A first portion of the signal may propagate along the first signal path and a second portion of the signal may propagate along the second signal path. A phase shifter may be disposed on the first signal path to shift a phase of the first portion to match a phase of the second portion. The phase-shifted first portion may be combined with the second portion to reduce or substantially eliminate an insertion loss caused by the isolation circuit.Type: GrantFiled: September 15, 2022Date of Patent: May 16, 2023Assignee: Apple Inc.Inventors: Oliver Georg Dorn, Björn Lenhart, Joonhoi Hur, Rastislav Vazny

Patent number: 11646857Abstract: Methods and system for using a multifunctional filter to minimize insertion loss in a multi-mode communications system are described. Specifically described is a multifunctional filter that is configurable to operate in a band-pass mode when a first type of signal is propagated through the multifunctional filter, and to operate in a low-pass mode when a second type of signal is propagated through the multifunctional filter. The multifunctional filter presents a lower insertion loss to the second type of signal when operating in the low-pass mode than in the band-pass mode.Type: GrantFiled: July 9, 2020Date of Patent: May 9, 2023Assignee: pSemi CorporationInventor: Dan William Nobbe
