An example frequency converter includes a drift canceling loop with a balanced delay and a linear signal path (e.g., linear with respect to frequency scaling, amplitude modulation, and/or phase modulation). One side of the drift canceling loop includes a fixed delay, and the opposite side includes an adjustable, complementary delay. The adjustable, complementary delay facilitates precision matching of the signal delays on each side of the loop over a range of frequencies, which results in a significant improvement in noise cancelation, particularly at large offsets to the carrier, while permitting the use of a higher noise, but very fast tuning course scale oscillator. The linear signal path from the signal generator to an RF output facilitates modulation of the signal by the signal generator. A modular format is an advantageous embodiment of the invention that includes the removal of the frequency synthesizer's low phase noise reference into a separate module.

A communication system provides secure communication between two nodes in a self-organizing network without the need for a centralized security or control device. A first node of the two nodes is provisioned with one or more security profiles, auto-discovers a second node of the two nodes, authenticates the second node based on a security profile of the one or more security profiles, selects a security profile of the one or more security profiles to encrypt a communication session between the two nodes, and encrypts the communication session between the two nodes based on the selected security profile. The second node also is provisioned with the same one or more security profiles, authenticates the first node based on a same security profile as is used to authenticate the second node, and encrypts the communication session based on the same security profile as is used for encryption by the first node.

The present disclosure is directed to a method in a mobility management node and such a node for delivering data to a wireless communication device (WCD) served by the mobility management node, operating in a communication network comprising a network entity (NE) and a radio access network (RAN) node serving the WCD, the method comprises: obtaining capability information indicating whether the RAN node supports acknowledgement of a successful delivery of data to the WCD; receiving a data message sent by the NE comprising user data intended for the WCD; sending a control plane message comprising the user data to the RAN node for further delivery to the WCD; sending a response to the NE indicating the outcome of the data delivery.

This disclosure provides a User Equipment (UE), including: a transmitter configured to transmit at least one Protocol Data Unit (PDU) session identifier (ID), each of which indicates a PDU session that the UE needs to use in a Non Access Stratum (NAS) Service Request message to a Mobility Management Function (MMF) via an access network (AN) node when the UE has user data to send.

A handheld video game controller is operable in Bluetooth Low Energy (BLE) mode to allow for sending controller input data to a target BLE device in a manner that bypasses any operating system (OS) restrictions that might otherwise be imposed on game controller input. When operating in the BLE mode, the handheld video game controller pairs (establishes a radio link) with a BLE device executing a client application used for video game streaming. During gameplay, the video game executes on a host computer and the player provides user input to the game controller to control an aspect of the video game. In response to such user input, the game controller sends controller input data to the BLE device via a radio of the game controller. The player may switch between operating the game controller in BLE mode and receiver mode using input gestures on the game controller.
