Abstract: Systems and methods for transmitting beacon messages are described. A beacon message is transmitted from a first beacon device and broadcast to an area within a transmission range of the first beacon device. A mobile device receives and stores the message. When the mobile device is out of the range of the first beacon device and within the range of a second beacon device, the message is transmitted to the second beacon device and broadcast by the second beacon device.

Abstract: Techniques for optimizing configuration parameters in a wireless network may iteratively adjust one or more wireless configuration parameters during a first stage of an adjustment period until either a cost increase during a single iteration exceeds an upper cost threshold or (ii) the number of successive iterations exhibiting a per-iteration cost increase between the upper cost threshold and a lower cost threshold exceeds a threshold number of iterations. This may trigger the AP proceed to a second stage of the adjustment period, where the AP may adjust the same wireless configuration parameter in an opposite direction, maintain a value of the wireless parameter, or adjust a different wireless configuration parameter during the second stage. Progression between successive adjustment periods may be at least partially coordinated between APs in a group of APs.

Abstract: Provisioning of an electronic subscriber identity module (eSIM) to an embedded universal integrated circuit card (eUICC) is observed to acquire a captured payload. The captured payload is then used in replay test sessions. In a live test session, test equipment can be used to monitor the communication between an eSIM server and the eUICC in order to capture the payload transmitted from the eSIM server. In the live test session, the eUICC can be in a debug mode that persists an ability to generate the same keys. In the replay test sessions, the payload captured can be reused and the eUICC can regenerate the same keys to decrypt an encrypted eSIM in the payload. After an installation attempt, the eUICC can provide notifications to the test equipment. The eUICC can be stress-tested using methods described herein without consuming a large number of eSIMs from an eSIM server inventory.

Abstract: Convergence times associated with simulated annealing based (SA-based) optimization in wireless networks can be reduced by introducing an additional local or cell-level evaluation step into the evaluation of global solutions. In particular, new local solutions may be evaluated based on local performance criteria when the new solutions are in a global solution deemed to have satisfied a global performance criteria. New local solutions that satisfy their corresponding local performance criteria remain in the new global solution. New local solutions that do not satisfy their corresponding local performance criteria are replaced with a corresponding current local solution from a current global solution, thereby modifying the new global solution. The resulting modified global solution includes both new local solutions and current local solutions prior to being accepted as the current global solution for the next iteration.

Abstract: In certain exemplary embodiments, register banks are used to allow for fast beam switching (FBS) in a phased array system. Specifically, each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be preprogrammed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Additionally or alternatively, active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

Abstract: A communication terminal device is a mobile communication terminal device that carries out communication for voice calls. The communication terminal device measures an orientation and a displacement of the device itself, and determines whether or not a condition occurring when a user picks up the device in his/her hand is met. In the case where it is determined that the condition occurring when the user picks up the device in his/her hand is met, and in the case where it has been determined that the user's head area has been detected as being near, the communication terminal device specifies a voice call partner on the basis of the orientation measured before the head area was detected as being near or while the head area was detected as being near. Then, when a tap operation performed by the user is detected, the communication terminal device performs a notification processing for making a notification of the specified voice call partner, and then makes an outgoing call to the partner.
