Abstract: A UE may estimate the power headroom value when using shortened Transmission Time Intervals (sTTI). In one implementation, the power headroom value may be calculated based on an estimation of the UE transmission power over two or seven OFDM symbols. Alternatively or additionally, the power headroom value may be calculated based on an estimation of the UE transmission power over the period of an sTTI. Alternatively or additionally, the power headroom value may be calculated based on an average of the UE transmission power over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on a maximum or minimum of the UE transmission power measured over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on UE transmission power measured in the first or the last sTTI period in a subframe.

Abstract: Systems and methods of providing timing information for initial access in an unlicensed band are described. A UE monitors a new radio discovery signal (NRDS-U) window in an unlicensed band for a DRS transmission that is constrained to be transmitted within the NRDS-U window. The UE determines initial access information, including an offset that indicates when the DRS transmission occurs within the NRDS-U window, and engages in initial access dependent on the offset. The offset is from a radio frame or half radio frame boundary or the start of the NRDS-U window. The offset is indicated in three least/most significant bits an SSB index or from an sl-offset field in a MIB of the SSB. When the base station uses a DFS channel, the base station transmits a periodic signal to emulate a radar signal.

Abstract: A method is performed to provide assurance for a service enabled on a network. A definition of the service is received. The definition includes a service type, a service instance, and configuration information used to enable the service. From the service type and the service instance, a service tag that is unique to the service is generated so as to distinguish the service from other services on the network. Based on the definition, the service is decomposed into a subservice dependency graph of subservices and dependencies between the subservices. Based on the subservice dependency graph, the subservices are configured to record and report subservice metrics indicative of health states of the subservices. The subservice metrics are obtained from the subservices. The service tag is applied to the subservice metrics to produce service-tagged subservice metrics. The service-tagged subservice metrics are analyzed to determine a health state of the service.
