  • Patent number: 10327159
    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.

  • Patent number: 10320093
    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.

  • Patent number: 10312989
    Abstract: A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

  • Patent number: 10250759
    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.

  • Patent number: 10244489
    Abstract: The present disclosure relates to a method for efficiently performing power control in situations where the UE is connected to both a MeNB and SeNB. The MeNB determines a power distribution ratio for the power to be used by the UE for uplink transmission to the MeNB and SeNB, determines the parameters PEMAX,MeNB and PEMAX,SeNB and sends these parameters to the SeNB/UE for use in power control. Moreover, update of the power distribution ratio is performed by the MeNB with assistance by the UE, which provides the MeNB with information on the pathloss on the secondary radio link to the SeNB, preferably by transmitting a virtual power headroom report, regarding the secondary radio link to the SeNB, to the MeNB, from which the MeNB derives the information on the pathloss for the secondary radio link.

  • Patent number: 10243625
    Abstract: A rate-adaptive method of communicating over a multipath wireless communication system uses multiple links such that each end of a link uses multiple transmit and receive antennas. A number of independent streams that are to be transmitted for each link is determined based on an overall system performance measure. In addition, the system may also jointly determine the best modulation, coding, power control, and frequency assignment for each link, based on an overall system performance measure. In OFDM systems, the number of independent streams, as well as the modulation, coding, and power control, may be determined on a tone-by-tone basis based on an overall system performance measure.
