Abstract: In a wireless communication system, a peak to average power ratio (PAPR) may affect the efficiency of a power amplifier. To reduce a PAPR, a transmitting device may utilize a PAPR reduction precoding that changes a received signal without performance impact so the overall transmit PAPR is reduced. The transmitting device constructs a frequency domain (FD) response to the PAPR reduction precoding, estimates a channel to one or more receiving devices, and applies the PAPR reduction precoding to the estimated channel. The transmitting device constructs a multiple input multiple output (MIMO) precoding matrix considering the FD response of the PAPR reduction precoding and applies the MIMO precoding matrix and the PAPR reduction precoding to an FD signal. A receiving device applies the FD response conjugated to a received FD signal from the transmitting device and processes at least a received reference signal based on the PAPR reduction precoder.

Abstract: Aspects of the subject disclosure may include, for example, monitoring status of a network configured to provide end-to-end delivery of services to priority user equipment authorized according to a prioritized class of service and other user equipment not authorized for the prioritized class of service. The prioritized class of service extends a reserved network capacity for end-to-end delivery of a service via first domain including first network slices and a second domain including second network slices. A network interruption compromising the reserved capacity is determined based on the monitored status and integration of an alternate group of slices into one of the first network domain, the second network domain, or both to replace the compromised group of slices, is orchestrated. Integration of the alternate group of slices restores reserved network capacity according to the prioritized class of service. Other embodiments are disclosed.

Abstract: This disclosure provides methods, devices and systems for provisioning resources for wireless communications. Some implementations more specifically relate to provisioning such resources based on a mapping of wireless communication devices to a number of time sectors that occur periodically and do not overlap other time sectors. In some aspects, each wireless stations (STAs) in a basic service set (BSS) may be mapped to a respective time sector based on attributes associated with the BSS so that communications between a STA and its associated access point (AP) can only occur within the respective time sector(s) to which the STA is mapped. In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.

Abstract: Various arrangements for performing cellular network testing are presented herein. A test environment can be created for a production cellular network. A test can be defined for the cellular network within the testing environment then performed. An issue can be logged that indicates that a performance metric of the cellular network within the test environment was not met. The issue and the test environment are analyzed to identify a component responsible for the performance metric not being met. The cellular network as implemented in the test environment, the production network, or both can then be modified.

Abstract: A network traffic correlation engine monitors inbound and/or outbound connection information received from on each host computer system on a network. Each host device on the network store data logs corresponding to information corresponding to communications sent by the device and received by the device. The network traffic correlation engine correlates connections between different hosts throughout the network. If the network traffic correlation engine identified unmatched outbound and inbound connections, the network traffic correlation engine generates an alert to initiate further investigation and may also provide a mapping of the communications showing a possible start device for the connection and/or a type of access that the connections may now be providing.

Abstract: Reference signal sequence mapping and de-mapping methods, and an apparatus are provided, to resolve a problem in a conventional technology that time-domain overheads of a reference signal of a single-carrier waveform are relatively large. In this application, a sending device maps a reference signal sequence to a modulation symbol set, to obtain a multiplexing set, where the multiplexing set occupies one single-carrier time domain symbol. Compared with a solution in which a reference signal sequence occupies one single-carrier time domain symbol, the solution in this application reduces time-domain overheads of the reference signal. In addition, to correctly perform channel estimation or channel sounding for the reference signal, different reference signal sequences meet conditions such as orthogonality or conjugate orthogonality, and locations of the reference signal sequences in different multiplexing sets further meet corresponding conditions, and so on.

Abstract: A compliance management system generates an enterprise data schema based on a compliance regulation. The system monitors interactions over a network with resources subject to the compliance regulation to generate interaction data sets. The system processes the interaction data sets against the enterprise data schema to categorize at least some of the interactions to trigger events associated with the categories, generate corresponding to the events, and track a compliance metric for each of the tasks generated. The system updates the enterprise data schema based on the compliance metric and the interaction data sets.

Abstract: A geofencing service establishes an initial geofence for monitoring devices connected to a cellular network. Upon receipt of a notification generated and transmitted by a device that crossed the geofence, the service determines a difference in location of the device at the times of notification generation and transmission based on coordinates included in the notification. A difference in location that satisfies a criterion indicates that the geofence corresponds to a geographic location with poor cellular network connectivity. The service modifies the geofence radius based on available signal strength data and enforces the resulting modified geofence. After this first radius modification, the service determines quality of network connectivity at geographic locations corresponding to internally tracked “shadow” geofences and modifies the geofence radius if device coordinates indicate that a shadow geofence corresponds to an area with sufficient connectivity.
