Abstract: A data demodulation method, apparatus, and system are presented. The method includes obtaining notification information indicating that UE is in a high-speed moving state; performing time-frequency synchronization processing on first downlink data according to the notification information to obtain second downlink data; and performing demodulation processing on the second downlink data to obtain third downlink data, where in the demodulation processing, inter-TTIs filtering for a channel estimation is not performed, or a filtering coefficient as a weight of a current TTI for a channel estimation is greater than a filtering coefficient as a weight of a TTI that is at the time when the UE is in the non-high-speed moving state for a channel estimation. The demodulation method is applicable to a high-speed scenario for improving a downlink data throughput of the UE.

Abstract: An apparatus is configured to protect the privacy of shared objects by loading shared object into a user memory of a rich execution environment. The shared object has an encrypted segment and metadata. A request for decryption is sent to a trusted execution environment and the encrypted segment is decrypted based on the metadata and a predetermined platform key to produce a decrypted segment. The decrypted segment is written into the shared object. A request to lock the shared object is sent and a memory occupied by the shared object is locked or set to execute only. The lock of the memory region occupied by the decrypted shared object maps the memory region to be non-readable and non-writable to applications executing at a first privilege level and to the operating system kernel executing at a second privilege level.

Abstract: A data demodulation method, apparatus, and system are presented. The method includes obtaining notification information indicating that user equipment (UE) is in a high-speed moving state; performing time-frequency synchronization processing on first downlink data according to the notification information to obtain second downlink data; and performing demodulation processing on the second downlink data to obtain third downlink data, where in the demodulation processing, inter-transmission time intervals (TTIs) filtering for a channel estimation is not performed, or a filtering coefficient as a weight of a current TTI for a channel estimation is greater than a filtering coefficient as a weight of a TTI that is at the time when the UE is in the non-high-speed moving state for a channel estimation. The demodulation method is applicable to a high-speed scenario for improving a downlink data throughput of the UE.

Abstract: Embodiments of the present invention provide a communication method, a communications apparatus, and a base station, and relate to the communications field. The method includes: obtaining, by a terminal, a timing advance TA offset of a first cell set, and determining, by the terminal, a TA difference between the first cell set and each cell set of a second base station according to the TA offset of the first cell set after a TA of the first cell set is adjusted. The first cell set includes at least one cell, and the at least one cell is a cell of a first base station and has a TA needs to be adjusted;
