Abstract: Disclosed is a method for implementing a Primary Synchronization Signal (PSS) in the time domain, including that: PSS time domain sequences with different sampling rates and with configuration represented by NID(2) are pre-stored; a PSS time domain power weighting related parameter is obtained according to a PSS power control related parameter, a cell related parameter and timing information; power weighting processing is performed on the PSS time domain sequences to obtain weighted PSS time domain sequences according to the pre-stored PSS time domain sequences with different sampling rates and with configuration represented by NID(2) and the PSS time domain power weighting related parameter; and addition operation is performed on the weighted PSS time domain sequences and time domain data of signals and channels other than the PSS. Also disclosed are an apparatus for implementing a PSS in the time domain and a computer storage medium.

Abstract: Embodiments of the present invention disclose a method, computer program product, and system for managing activation keys associated with a computing system. In one embodiment, in accordance with the present invention, the computer implemented method includes the steps of detecting a repair activity on a computing system, determining whether at least one system identifier (ID) associated with a component of the computing system has changed in comparison to system IDs associated with components of the computing system before the detected repair activity, responsive to determining that at least one system ID associated with a component of the computing system has changed, retrieving one or more activation keys that correspond to the determined at least one system ID, and determining whether the one or more retrieved activation keys are associated with a system ID that does not match any system ID associated with a component of the computing system.
