US 11664889

US Patent 11664889B2, titled "Communications in a wireless network," was granted to Intellectual Ventures II LLC. The sole inventor listed is Paul Howard. The application was filed on July 21, 2022, and the patent was issued on May 30, 2023.

Abstract:
The patent describes a user equipment (UE) configured to receive a control message over a physical control channel in a first time slot. This control message contains power control bits for multiple UEs, including the first UE. The UE then extracts its specific power control information from this message and transmits a signal over a physical control channel to a base station in a second time slot, with its transmission power level adjusted based on the extracted information.

Independent Claims Overview:

• Claim 1 (First User Equipment (UE) Apparatus): This claim describes a user equipment (UE) comprising a transmitter, a receiver, and a processor. The receiver and processor are configured to obtain a control message via a physical control channel in a first time slot, which also includes a downlink shared channel. This control message contains power control instructions for several UEs, including the particular UE itself. The processor is further designed to extract its own power control information from this message. Finally, the transmitter and processor work together to send a signal over a physical control channel to a base station in a second time slot, with the transmission power level adjusted according to the extracted power control information.
• Claim 5 (Method performed by a first UE): This claim outlines a method executed by a first UE. The method involves receiving a control message over a physical control channel in a first time slot, where this slot also carries a downlink shared channel and the message includes power control bits for a group of UEs (including the first UE). The UE then extracts its specific power control information from this message and transmits a signal over a physical control channel to a base station in a second time slot, with its transmission power level determined by the extracted power control information.
• Claim 9 (Base Station Apparatus): This claim describes a base station equipped with a transmitter, a receiver, and a processor. The transmitter and processor are configured to send a control message over a physical control channel in a first time slot. This control message contains power control bits for multiple UEs (including a specific first UE), and the base station also transmits data over a downlink shared channel in the same first time slot. The base station's receiver and processor are further configured to receive a signal over a physical control channel from the first UE in a second time slot, where the power level of this received signal is determined by the control message previously transmitted by the base station.

As of the current date of April 26, 2026, the patent US11664889B2 is active. Publicly available information, last fetched on 2026-07-07, indicates ongoing litigation. A PTAB case, IPR2025-00221, was filed and is currently pending (instituted). Additionally, two US cases related to this patent family have been filed in the Texas Western District Court (cases 6:24-cv-00188 and 1:24-cv-00390). The anticipated expiration date for this patent is December 27, 2026.

A search of the CAFC 2026 dockets for patent number 11664889 did not return any direct results as of April 26, 2026. This typically means no appeal directly concerning this patent, such as from an IPR decision or district court ruling, has reached the Court of Appeals for the Federal Circuit and been docketed in 2026 yet.US Patent 11664889B2, titled "Communications in a wireless network," was granted to Intellectual Ventures II LLC.
