Patent number: 11595950Abstract: To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.Type: GrantFiled: April 21, 2022Date of Patent: February 28, 2023Assignee: Apple Inc.Inventors: Mo-Han Fong, Hang Zhang, Sophie Vrzic, Robert Novak, Jun Yuan, Dong-Sheng Yu

Patent number: 11581990Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.Type: GrantFiled: May 13, 2021Date of Patent: February 14, 2023Assignee: Apple Inc.Inventors: Gang Xiong, Pingping Zong, Yujian Zhang, Mo-Han Fong, Jong-Kae Fwu

Patent number: 11258489Abstract: Aspects of the present invention provide additional MAC functionality to support the PHY features of a wireless communication system framework. The additional MAC functionality aids in enabling feedback from wireless terminals to base stations. In some aspects of the invention the feedback is provided on an allocated feedback channel. In other aspects of the invention the feedback is provided by MAC protocol data units (PDU) in a header, mini-header, or subheader. The feedback may be transmitted from the wireless terminal to the base station autonomously by the wireless terminal or in response to an indication from the base station that feedback is requested. Aspects of the invention also provide for allocating feedback resources to form a dedicated feedback channel. One or more of these enhancements is included in a given implementation. Base stations and wireless terminals are also described upon which methods described herein can be implemented.Type: GrantFiled: January 22, 2020Date of Patent: February 22, 2022Assignee: Apple Inc.Inventors: Hang Zhang, Mo-Han Fong, Peiying Zhu, Jianglei Ma, Wen Tong
