Abstract: A device with key attestation features comprises an operating system stored in its memory, the operating system comprising a secure environment including a trusted application, and two or more device certificates, each associated with a device key pair, stored in the memory of the device. The trusted application is configured to handle key pair generation requests and key pair attestation requests to read an indication of a preferred device certificate. An attestation certificate that is generated in response to the key pair attestation request is then signed using one of the two or more device certificates with its associated device key pair based on the indication of a preferred device certificate.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and provide a random access method and an apparatus, to resolve a prior-art problem that user equipment cannot accurately select a resource on a non-anchor carrier to perform random access. The method includes: measuring, by user equipment UE in a first measurement period T1, reference signal received power (RSRP) W1 on an anchor carrier; determining, by the UE, a first coverage level based on W1; and determining, by the UE, a first resource based on the first coverage level, where the first resource is used by the UE to perform random access on a non-anchor carrier.

Abstract: Embodiments of the present invention relate to a channel estimation method, a base station, user equipment UE, and a system. The method includes: setting up, by a base station, a connection to user equipment UE; and sending, to the UE, notification information indicating that the UE is in a radio remote scenario, where the notification information is used to instruct the UE to perform channel estimation by using a channel estimation algorithm applicable to the radio remote scenario, and the channel estimation algorithm is used to perform channel estimation on a signal that is obtained after downlink signals from multiple radio remote units RRUs are superposed. The UE can perform channel estimation by using the appropriate channel estimation algorithm, to effectively improve accuracy of the channel estimation, thereby effectively improving a downlink data throughput of the UE.

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.
