Abstract: Aspects of this disclosure relate to an improved coordinated multipoint (CoMP) network operating in a millimeter wave frequency band in which user equipment (UEs) combine signals received across multiple spatial beams from multiple base stations. The improved CoMP network can achieve high throughput, low latency, and/or high reliability at millimeter wave frequencies while maintaining a reasonable network complexity (e.g., lower network overhead than CoMP networks implemented with coherent combining). For example, the improved CoMP network can include one or more base stations and one or more UEs. Multiple base stations can transmit the same data across multiple spatial beams to a UE at the same time. The base stations may use information provided by a UE to identify an active set of base stations and/or spatial beams to serve the UE.

Abstract: Systems and methods for initializing a robot to autonomously travel a route are disclosed. In some exemplary implementations, a robot can detect an initialization object and then determine its position relative to that initialization object. The robot can then learn a route by user demonstration, where the robot associates actions along that route with positions relative to the initialization object. The robot can later detect the initialization object again and determine its position relative to that initialization object. The robot can then autonomously navigate the learned route, performing actions associated with positions relative to the initialization object.

Abstract: Aspects of this disclosure relate to a pair of wireless communication devices wirelessly communicating with a network system in a coordinated manner. The wireless communication devices of the pair can be in communication with each other via a wireless peer-to-peer link.

This can enable the primary wireless communication device to communicate with the network system at a higher data rate and/or at a higher MIMO rank.

Abstract: One example provides a computer-implemented method for reading data stored as birefringence values in a storage medium. The method comprises acquiring an image of a voxel of the storage medium, applying a first low-pass filter with a first cutoff frequency to the image of the voxel to obtain a first background image, applying a second low-pass filter with a second cutoff frequency to the image of the voxel to obtain a second background image, the second cutoff frequency being different than the first cutoff frequency, determining an enhanced background image from the first background image and the second background image, determining birefringence values for the enhanced background image, determining birefringence values for the image of the voxel, and correcting the birefringence values for the image of the voxel based upon the birefringence values for the enhanced background image.

Abstract: Aspects of this disclosure relate to reference signal channel estimation. A wireless communication channel between two nodes can be estimated based on a received reference signal, such as a Sounding Reference Signal. Techniques are disclosed to improve performance of reference signal channel estimation and make channel estimates more robust in the presence of one or more of a variety of impairments. Frequency domain processing and/or time domain processing can be performed to reduce distortion in channel estimates.

Abstract: Various technologies described herein pertain to enforcing control flow integrity by adding instrumentation when source code is compiled or binary code is rewritten. An indirect call to a control transfer target (e.g., in the source code, in the binary code, etc.) can be identified. Moreover, the instrumentation can be inserted prior to the indirect call. The instrumentation can use a bit from a bitmap maintained by a runtime to verify whether the control transfer target is valid. When an executable image that includes the inserted instrumentation runs, execution can be terminated and/or other appropriate actions can be taken when the control transfer target is determined to be invalid; alternatively, execution can continue when the control transfer target is determined to be valid.

Abstract: Aspects of the disclosure relate to a multipoint environment that enables a station (STA) to communicate with multiple access points (APs) and an AP to communicate with multiple STAs in a single wireless protocol stack. For example, a STA can authenticate simultaneously with multiple APs and decode any data packet that includes in a header a destination address that matches an address of the STA, irrespective of the source address included in the header of the data packet. Similarly, an AP can decode any data packet that includes in a header a destination address that matches an address of the AP or that matches a wildcard address associated with the AP, irrespective of the source address included in the header of the data packet.

Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.

Abstract: Devices, systems, and methods can be used including receiving motion data, categorizing the motion data into portions of a minute that indicate activity or a workout, and automatically determining an accurate number of active minutes for an individual.

Abstract: Aspects of the disclosure relate to a selection scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network to identify which users to schedule simultaneously during the same time slot. For downlink communications and a particular frequency wholeband or sub-band, the scheduler can determine downlink channel information using uplink channel information for channels between base stations and UEs. The scheduler can then determine a strength of the channels using the downlink channel information, order the UEs using a fairness metric based on the channel strengths, and compute one or more QR decompositions to identify whether a spatial dimension of a UE is roughly or approximately orthogonal to spatial dimension(s) of other UEs selected to be served during a time slot being scheduled. If the spatial dimensions are roughly or approximately orthogonal, the scheduler selects the UE to be served at the same time as other UEs already selected.
