SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD. exhibits a highly concentrated patent strategy, with an overwhelming 90.9% of its portfolio dedicated to Wireless Networks, which saw a significant surge in 2024 with a 333.3% YoY growth. This focus is further emphasized by the complete decline in patenting activity across several smaller categories like Operating Systems & Program Control and Web & Cloud Service Protocols, both experiencing 100.0% YoY declines in 2025, indicating a clear shift away from these areas towards core wireless communication technologies.

Cell-specific reference signal configuration method and device, storage medium, base station, and user equipment

Filed:2020-08-20Pub:2025-01-07
Applicant:SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

A cell-specific reference signal configuration method and device, a storage medium, a base station, and a UE are provided. The method includes: determining to configure a regular cell-specific reference signal in a current time slot; determining an SSB in the current time slot based on the SSB existing in the current time slot, or determining an SSB in a previous SSB time slot based on an SSB not existing in the current time slot and indicating a modulation mode of the regular cell-specific reference signal in the current time slot using modulation mode indication information in the determined SSB, or determining the modulation mode of the regular cell-specific reference signal to be a preset modulation mode, wherein a peak-to-average ratio of the modulation mode of the regular cell-specific reference signal isn't greater than that of data to be demodulated by using the regular cell-specific reference signal.
