Patent number: 11758408Abstract: There is provided a method and apparatus for data transmission using shared radio bearer in order to simplify the operation of RAN access node by reducing signalling overhead related to mobility and simplifying per UE RBs setup/release operation. Using the shared radio bearer, UE mobility operation becomes transparent to access node (e.g. edge cell) and to UE. There is also provided a method and apparatus for simplifying the operation of UE for RBs setup/release and to make the Layer 2 (L2) operation independent from mobility (e.g. independent from handover).Type: GrantFiled: September 5, 2019Date of Patent: September 12, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Hang Zhang, Jaya Rao, Sophie Vrzic

Patent number: 11711785Abstract: Embodiments of the disclosure provide methods and systems for sidelink resource allocation in user equipment (UE) groups. The method includes, receiving, by a UE, from a radio access network (RAN) node, a first resource configuration message including configuration information for sidelink resources indicated by a sidelink resource grant and conditions for using sidelink resources of the sidelink resource grant. The method further includes receiving, from a second UE of the UE group, a second sidelink resource configuration message, the second sidelink resource configuration message including an activation indicator to activate at least a portion of the sidelink resources indicated by the sidelink resource grant. The method further includes determining the sidelink resources to be used for sidelink transmissions by combining the first and second sidelink resource configuration messages.

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: 11515969Abstract: Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions.Type: GrantFiled: March 29, 2021Date of Patent: November 29, 2022Assignee: Apple Inc.Inventors: Mo-han Fong, Sophie Vrzic, Robert Novak, Jun Yuan, Dong-Sheng Yu

Patent number: 11509431Abstract: Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.Type: GrantFiled: July 27, 2020Date of Patent: November 22, 2022Assignee: Apple Inc.Inventors: Robert Novak, Mo-Han Fong, Hang Zhang, Sophie Vrzic

Patent number: 11425713Abstract: A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection.Type: GrantFiled: June 14, 2020Date of Patent: August 23, 2022Assignee: Apple Inc.Inventors: Sophie Vrzic, Jun Yuan, Mo-Han Fong, Robert Novak, Dong-Sheng Yu, Jianglei Ma
