Patent number: 12218762Abstract: Hybrid automatic repeat request (HARQ) processes may be transmitted via configured grants as well as scheduled grants. The configured grants may include time and frequency resources, and transmissions may occur across contiguous transmissions. HARQ process information, such as HARQ IDs and redundancy versions, may be communicated via a control channel, and the control channel may be multiplexed with the transmission resources of the configured grants. Retransmission timers may be used for HARQ processes conveyed via configured grants, and the transmitting apparatus may signal to a receiver when to send an acknowledgement. An acknowledgement may take the form of bitmaps for code block groups of a HARQ. A configured grant may be selected from among multiple configured grants based upon low latency, for example. A group of configured grants may be activated or deactivated via a single command.Type: GrantFiled: August 8, 2019Date of Patent: February 4, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Lakshmi R. Iyer, Joseph M. Murray, Mohamed Awadin, Qing Li, Yifan Li, Guodong Zhang, Pascal M. Adjakple

Publication number: 20250039887Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.Type: ApplicationFiled: September 26, 2024Publication date: January 30, 2025Applicant: InterDigital Patent Holdings, Inc.Inventors: Allan Y.
