A dual-band transceiver receives an incoming radio-frequency signal that includes a multipath self-interference component generated by the transmission of an outgoing radio-frequency signal. The transceiver creates a plurality of reference signals from the outgoing radio-frequency signal by introducing delay values with respect to the outgoing signal. The transceiver adjusts the amplitude and phase of each of the delayed reference signals and combines the resulting signals with the incoming radio-frequency signal to cancel the self-interference component. The delay values may be determined adaptively. The systems and methods described herein are particularly useful for dual-band transceivers capable of communicating simultaneously using Long-Term Evolution (LTE) wideband signals and Public-Safety Narrowband (PSNB) signals.Type: GrantFiled: April 28, 2014Date of Patent: May 10, 2016Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Mark Rozental, Nir Corse, Kevin G.

Patent number: 9179465Abstract: Devices and methods for adjusting resource management procedures based on machine device capability information are disclosed. In one aspect, a method for adjusting resource management procedures in a machine device communicating with a node operating in a communication network includes receiving a first message from the machine device, the first message including machine device capability information, processing the received machine device capability information to determine an adjustment to a resource management procedure, and transmitting a second message to the machine device, the second message including the determined resource management procedure adjustment. The first and second messages may be radio resource control (RRC) messages, such as RRC connection request and setup messages.Type: GrantFiled: October 2, 2012Date of Patent: November 3, 2015Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Konstantinos Dimou, Kumar Balachandran, Havish Koorapaty, Chester Park

Patent number: 9160464Abstract: A method for operating a receiver and a device are provided. The device comprises a first and a second antenna, a receiver operationally coupled to the first antenna and a transceiver operationally coupled to the second antenna. The receiver receives information in bursts on a first band of radio frequencies. A controller of the device measures signal strength of the information received with the receiver, compares the measured signal strength to a reference value and enables operation of the transceiver if the measured signal strength is above the reference value, and limits operation of the transceiver during reception of the bursts if the measured signal strength is below the reference value.Type: GrantFiled: September 19, 2005Date of Patent: October 13, 2015Assignee: Nokia Technologies OyInventors: Marko Leinonen, Niko Kiukkonen, Jari Junell, Pertti Kangas, Heikki Mattila, Antti Kangas, Jukka Kansanaho

Patent number: 9084224Abstract: A method and apparatus are described for providing multimedia broadcast multicast services (MBMS) service feedback. A wireless transmit/receive unit (WTRU) may receive an MBMS service query message over an MBMS control channel and transmit an MBMS service response. The MBMS service query message and MBMS service response message may be radio resource controller messages. The MBMS service query message may include MBMS service identifiers which identify MBMS services that the WTRU is receiving or intending to receive. The WTRU may generate a report with MBMS service identifier index values, where each MBMS service identifier index value indicates a position of a service identifier corresponding to an MBMS service in the original query list that the WTRU is currently receiving or intending to receive. The MBMS service status query message may be received alone or along with a MBSFNAreaConfiguration message. The WTRU may respond within a predetermined or configured time limit.Type: GrantFiled: April 4, 2014Date of Patent: July 14, 2015Assignee: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Peter Wang, Janet A. Stern-Berkowitz, Nobuyuki Tamaki, Stephen E. Terry, Kai Liu

Patent number: 9001706Abstract: A method for use in a cellular access system is disclosed. The system comprises at least one Radio Base Station (RBS) and a User Equipment (UE), which can send and receive data blocks to and from each other, comprising sequence numbers. The method, performed by a reporting party, comprises sending a transmission comprising a report to the report receiving party, said report comprising information on whether or not data blocks have been received successfully. The method further comprises sending said report together with data to the report receiving party or to another party. The method further comprises attaching addresses for a recipient of the data blocks and for the report in the transmission. The method further comprises deciding the contents of the report using at least one of a list of priority rules which have been given an internal priority ranking.Type: GrantFiled: November 26, 2013Date of Patent: April 7, 2015Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Ylva Timner, Mårten Sundberg, Håkan Persson, Andreas Bergström
