Patent number: 9661585Abstract: According to some embodiments, a first network node manages a transmit power of a first wireless device capable of device-to-device, D2D, communication. The first network node receives at least one measurement report from at least one of the first wireless device and a second wireless device in D2D communication with the first wireless device. The measurement report indicates a received signal measurement or path loss with respect to the other of the first wireless device and the second wireless device and/or a received signal measurement or path loss with respect to a victim node. The first network node sends the first wireless device instructions to make an adjustment of the transmit power that the first wireless device uses in the D2D communication. The adjustment is at least partially based on the received measurement report.Type: GrantFiled: January 14, 2015Date of Patent: May 23, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gary Boudreau, Christian Bergljung, Muhammad Kazmi, Iana Siomina, Stefano Sorrentino

Patent number: 9648515Abstract: The present invention relates to device triggering in case of a congestion control. A triggering server transmits a device trigger request to a terminal over a communication network including a serving network node. The network node evaluates whether the connection can be established from the terminal to the server, including determining whether the network is congested and/or whether a back-off timer is running and/or the remaining time of the back-off timer at the terminal. Then the network node transmits a delivery delay indication to a device triggering control server to provide it with the delivery delay indication indicating at least one of impossibility of establishing the connection to the server after the trigger or a data transmission delay.Type: GrantFiled: November 26, 2012Date of Patent: May 9, 2017Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Genadi Velev, Jens Bachmann, Keigo Aso

Patent number: 9629160Abstract: Disclosed is a method and system for managing carriers on which a wireless communication system serves a UE. As disclosed, the system serves the UE on a set of one or more carriers. While serving the UE on the set of one or more carriers, the system determines that the UE should additionally be served on at least one other carrier. The system then selects the at least one other carrier, from a set of candidate carriers, based at least in part on the at least one other carrier being closest, of the set of candidate carriers, in the frequency spectrum to the set of one or more carriers. Based on the selecting, the system then adds the selected at least one other carrier to the set of one or more carriers to establish a modified set of carriers and serves the UE on the modified set of carriers.Type: GrantFiled: December 17, 2014Date of Patent: April 18, 2017Assignee: Sprint Spectrum L.P.Inventor: Volkan Sevindik

Patent number: 9614631Abstract: A framework for enabling a user equipment (UE) to apply interference suppression processing during network conditions that are favorable to interference suppression or that are known is provided. The framework includes an interference suppression (IS) time and frequency (time/frequency) zone, which can be scheduled by a serving base station and signaled to the UE. In an embodiment, the serving base station coordinates with the interfering base station(s) to create a network condition favorable to interference suppression at the UE during the IS time/frequency zone. In another embodiment, the serving base station opportunistically schedules the IS time/frequency zone for the UE whenever it determines favorable transmission parameters being used or scheduled for use by the interfering base station(s). The UE applies interference suppression processing within the IS time/frequency zone, thereby improving receiver performance.Type: GrantFiled: October 3, 2014Date of Patent: April 4, 2017Assignee: Avago Technologies General IP (Singapore) Pte.
