Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.Type: GrantFiled: August 1, 2016Date of Patent: January 2, 2018Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Juan Montojo, Arnaud Meylan

Patent number: 9848352Abstract: An apparatus and method reduce power consumption in a broadband wireless communication system. A transmitting end apparatus that includes a plurality of transmit (Tx) antennas includes a control block, a Processor (DSP) block, a modem block, and at least one power controller. The control block determines a traffic amount based on an amount of used resources. The Digital Signal Processor (DSP) block performs scheduling by using a subset of Tx antennas and a subset of resources on a frequency axis if the traffic amount is less than a threshold. The modem block applies boosting to a signal transmitted using the subset of resources. And at least one controller turns off an operation of at least one power amplifier that corresponds to at least one Tx antenna that is not included in the subset of Tx antennas.Type: GrantFiled: November 18, 2014Date of Patent: December 19, 2017Assignee: Samsung Electronics Co., Ltd.Inventors: Yun-Seok Choi, Seung-Joo Maeng, Byung Chan Ahn

Patent number: 9844007Abstract: The present invention is designed to allow user terminals to detect small cells in the off state efficiently when the small cells are switched on and off dynamically. A radio base station that switches between a continuous transmission state and a discontinuous transmission state dynamically, has a power control section that executes power control so that the transmission power of a reference signal for cell detection that is transmitted in the discontinuous transmission state is lower than the transmission power of a reference signal that is transmitted in the continuous transmission state.Type: GrantFiled: June 23, 2014Date of Patent: December 12, 2017Assignee: NTT DOCOMO, INC.Inventors: Hiroki Harada, Kazuaki Takeda, Satoshi Nagata

Patent number: 9832738Abstract: Method and apparatus for controlling a transmit power of a mobile station are disclosed. Mobile stations in direct communication on a cross link (XL) receive control parameters from a base station. A first mobile station (a receiving mobile station) may calculate a correction parameter for power offset for transmissions from a second mobile station (a transmitting mobile station) to the first mobile station, and send it to the second mobile station. The correction parameter may be generated within the maximum and minimum limits. The second mobile station may calculate a transmit power level for a transmission to the first mobile station based on the correction parameter, measurements on resources allocated for cross links for mobile station-to-mobile station direct communications, an interference measurement received from the first mobile station, and a path loss to the first mobile station.Type: GrantFiled: September 19, 2016Date of Patent: November 28, 2017Assignee: InterDigital Patent Holdings, Inc.Inventor: Eldad M.

Patent number: 9820202Abstract: A method for changing a communication network for video communication is provided. The method includes performing, by a user equipment (UE), video communication through a mobile communication network; searching for whether there is a wireless local area network (WLAN) accessible by the UE; displaying, if a WLAN accessible by the UE is found, the accessible WLAN; and when the displayed WLAN is selected by a user, changing a communication network for the video communication to perform the video communication through the selected WLAN.Type: GrantFiled: April 21, 2017Date of Patent: November 14, 2017Assignee: Samsung Electronics Co., Ltd.Inventors: Hyung-Rae Cho, Sun-Ae Kim, Ji-Young Kwahk, Hyun-Joo Oh

Patent number: 9820303Abstract: Multicast transmissions are efficient but do not allow for individual acknowledgement that the data was received by each receiver. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol is provided that uses a novel multi-destination burst transmission protocol in multimedia isochronous systems. The transmitter establishes a bi-directional burst mode for multicasting data to multiple devices and receiving Reverse Start of Frame (RSOF) delimiters from each multicast-destination receiver in response to multiple SOF delimiters, thus providing protocol-efficient multi-destination acknowledgements.Type: GrantFiled: September 10, 2015Date of Patent: November 14, 2017Assignee: STMicroelectronics, Inc.Inventors: Oleg Logvinov, Aidan Cully, David Lawrence, Michael Macaluso

Patent number: RE47110Abstract: Systems and methodologies are described that facilitate reporting an uplink power headroom (UPH) during an E-DCH transmission in a CELL_FACH state. For a E-DCH transmission, a reduced measurement period can be utilized in order to report a UPH measurement. In particular, the reduced measurement period can be less than 100 milliseconds. The UPH measurement can be communicated based upon receipt of AICH/E-AICH and transmission of DPCCH for a configurable number of radio frames. The UPH measurement can be based upon the transmitted power prior to actual data transmission. Additionally, the UPH measurement can be included within scheduling information portion of a MAC header.Type: GrantFiled: July 24, 2014Date of Patent: October 30, 2018Assignee: QUALCOMM IncorporatedInventors: Sharad Deepak Sambhwani, Mehmet Yavuz
