Company patents

SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD. exhibits a highly concentrated patent strategy, with an overwhelming 91.7% of its portfolio in Wireless Networks, showing consistent growth until a -40.0% decline so far in 2026. Surprisingly, despite its core focus, categories like Operating Systems & Program Control and Web & Cloud Service Protocols, while small, have seen significant year-over-year fluctuations, including a -100.0% decline in 2025 for both, indicating a potential shift away from these areas.

METHOD AND APPARATUS FOR DETERMINING RESOURCE LOCATION, TERMINAL, AND NETWORK DEVICE

Filed:2022-07-14Pub:2024-10-10
Applicant:SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

A method and apparatus for determining a resource location, a terminal, and a network device are provided. The method includes the following. A network device sends configuration information. A terminal obtains the configuration information. The terminal determines a first resource location according to the configuration information, where the first resource location is used for the terminal in a first state to monitor a first wake-up signal (WUS), and the first WUS is used for triggering transition of the terminal to a second state from the first state. Since the configuration information is used for determining the first resource location, it is possible to determine, based on the configuration information, a resource location used for monitoring the first WUS in the first state, thereby ensuring robustness and stability of system communication while reducing network overhead and power consumption of the terminal.

Method for computational-power sharing and related device

Filed:2021-04-13Pub:2024-01-16
Applicant:SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

A method for computational-power sharing is provided. In implementations of the disclosure, a computational-power sharing network element is connected with a network to perform control plane transmission and data plane transmission, or the computational-power sharing network element is connected with the network to perform control plane transmission. The computational-power sharing network element acquires computational-power demand information transmitted by a computing demand side and available computational-power information transmitted by at least one computing cooperation side. The computational-power sharing network element determines a computing cooperation side from the at least one computing cooperation side according to the computational-power demand information and the available computational-power information, and directly or indirectly indicates the computing cooperation side to complete a computing task of the computing demand side, where the computing cooperation side is able to provide computational power for the computing demand side.

COMPUTING POWER SHARING-RELATED EXCEPTION REPORTING AND HANDLING METHODS AND DEVICES, STORAGE MEDIUM, AND TERMINAL APPARATUS

Filed:2021-08-05Pub:2023-07-06
Applicant:SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

Provided are a method and an apparatus for reporting and handling an exception in computing power sharing, a storage medium, and a terminal device. The method for reporting an exception in computing power sharing includes: detecting a current hardware state and a current battery state; and reporting an exception to a network unit, in a case that the hardware state or the battery state reaches a preset exception threshold, or in a case that a change of the hardware state or a change of the battery state reaches a preset reporting threshold. The method for handling an exception in computing power sharing includes: receiving an exception reported from a cooperative computing terminal; determining a total workload assigned to the cooperative computing terminal and a remaining workload of the cooperative computing terminal; and determining, based on the exception and the remaining workload, to reassign the remaining workload or the total workload.
