Patent number: 12052709Abstract: This application provides a method for transmitting hybrid automatic repeat request HARQ feedback information and a communications apparatus. A terminal device receives downlink data channels. Each of the downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups. The terminal device determines a first transmission resource based on first information including the transmission parameter groups, and sends, on the first transmission resource, HARQ feedback information corresponding to the downlink data channels, so that a plurality of pieces of HARQ feedback information can be smoothly fed back. This helps improve service transmission reliability.Type: GrantFiled: November 1, 2021Date of Patent: July 30, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Ruixiang Ma, Lei Guan, Yuan Li

Patent number: 12047142Abstract: Certain aspects provide techniques for precoder matrix quantization for compressed channel state information (CSI) feedback. A method for wireless communications by a user equipment (UE) includes receiving a CSI report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE to report, for a plurality of selected beams at a plurality of time domain taps, a frequency domain compression basis vector and a plurality of linear combination coefficients associated with the frequency domain compression. For each of the beams, the UE groups the time domain taps into at least first and second groups. The groups each can have zero, one, or more than one time domain taps. The UE quantizes the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping.Type: GrantFiled: January 22, 2020Date of Patent: July 23, 2024Assignee: QUALCOMM IncorporatedInventors: Min Huang, Chenxi Hao, Yu Zhang, Chao Wei, Liangming Wu, Qiaoyu Li

Patent number: 12047168Abstract: According to a possible embodiment, a control channel can be received in a first downlink slot. The control channel can contain DCI with a downlink DCI format. The DCI can contain a CSI report trigger that triggers a CSI report. The DCI can schedule PDSCH transmissions repeated a number of times in a set of downlink slots. Each PDSCH transmission of the repeated PDSCH transmissions can be in a separate downlink slot. A CSI report can be generated in response to receiving the CSI report trigger. At least one uplink resource to transmit the generated CSI report can be determined. The at least one uplink resource can be determined based on the number of repeated PDSCH transmissions. The generated CSI report can be transmitted in the determined at least one uplink resource.Type: GrantFiled: September 27, 2019Date of Patent: July 23, 2024Assignee: Lenovo (Singapore) Pte.

Patent number: 12047922Abstract: The present invention relates to a transmission and reception method of a radio signal by a terminal in a wireless communication system. According to the present specification, disclosed is a method comprising the steps of: determining whether or not transmission of an uplink radio signal or reception of a downlink radio signal allocated to a terminal is possible on a slot configured to comprise at least one of one or more downlink symbols for downlink transmission, one or more flexible symbols and one or more uplink symbols for uplink transmission; and controlling the transmission of the uplink radio signal or the reception of the downlink radio signal on the basis of the determination. According to the present invention, the terminal can transmit the uplink radio signal even if the configuration of the slot is changed, and thus uplink radio signal transmission omission or unnecessary retransmission of the uplink radio signal can be prevented.Type: GrantFiled: July 5, 2022Date of Patent: July 23, 2024Assignee: WILUS INSTITUTE OF STANDARDS AND TECHNOLOGY INC.Inventors: Kyungjun Choi, Minseok Noh, Jinsam Kwak

Patent number: 12034502Abstract: Method, apparatus, and computer program product for a user equipment to receive a downlink control information message from an access point in a wireless communications network and to echo a new beam index in the PUCCH feedback resource in response to the message indicating a PUCCH feedback resource and containing a beam change information or in response to the message indicating a downlink grant containing a beam change indication MAC control element but so CSI-feedback is scheduled for the PUCCH feedback resource. If a scheduling request resource is indicated by the message or the MAC control element, the user equipment is triggered to transit a scheduling request on that indicated scheduling request resource. If a scheduling request resource is not indicated by the message or the MAC control element, the user equipment is triggered to perform a scheduling request procedure on a periodic scheduling request resource.Type: GrantFiled: April 29, 2021Date of Patent: July 9, 2024Assignee: Nokia Technologies OyInventors: Timo Koskela, Samuli Turtinen, Juho Pirskanen

Patent number: 12035359Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access channel (RACH) procedure with a base station. The UE may receive a message configuring a RACH preamble occasion and an uplink data occasion. The message may be a radio resource control (RRC) message or a system information (SI) message. In some cases, the UE may determine if the RACH preamble occasion, the uplink data occasion, or both are restricted for cancellation based on the message. The UE may determine when to monitor a downlink control channel for dynamic scheduling based on determining which occasions are restricted for cancellation and may transmit a RACH message based on monitoring—or not monitoring—the downlink control channel for dynamic scheduling preempting a RACH occasion. In some other cases, a base station may schedule transmissions to not overlap with configured RACH occasions.Type: GrantFiled: March 4, 2022Date of Patent: July 9, 2024Assignee: QUALCOMM IncorporatedInventors: Jing Lei, Wanshi Chen, Linhai He
