Patent number: 9713158Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.Type: GrantFiled: June 21, 2016Date of Patent: July 18, 2017Assignee: QUALCOMM IncorporatedInventors: Tingfang Ji, Peter Gaal, William R. Panton, Gene Fong, Philip D. Coan, Sumit Verma, Edward George Tiedemann, Jr.

Patent number: 9338695Abstract: Techniques for signaling carrier bandwidths supported by a user equipment (UE) for carrier aggregation are disclosed. A UE may be configured with a plurality of carriers for carrier aggregation. Each carrier may have one carrier bandwidth of a set of possible carrier bandwidths. The set of possible carrier bandwidths may be dependent on a band in which the carrier belongs. Multiple combinations of carrier bandwidths for the plurality of carriers may be possible. The UE may identify at least one supported carrier bandwidth combination for the plurality of carriers. Each of the supported carrier bandwidth combinations may include a particular carrier bandwidth for each configured carrier. The UE may send signaling indicative of the at least one supported carrier bandwidth combination. The UE may thereafter communicate on the plurality of carriers based on a carrier bandwidth combination selected from the supported carrier bandwidth combination(s).Type: GrantFiled: November 28, 2012Date of Patent: May 10, 2016Assignee: QUALCOMM IncorporatedInventors: Masato Kitazoe, Tingfang Ji, Peter Gaal, Gene Fong, Lorenzo Casaccia, Oronzo Flore

Patent number: 9307549Abstract: To support very high QAM rates, a user equipment (UE) needs extremely good signal-to-noise ratio (SNR). Using a receiver configuration that improves SNR comes at the expense of higher power consumption. However, consuming higher power to support very high QAM rates when poor channel conditions are present is a waste of power. By correlating the modulation and coding scheme used by the UE with the UE channel quality estimate, the UE can modify the receiver configuration to improve SNR only when channel conditions support very high QAM rates.Type: GrantFiled: March 12, 2014Date of Patent: April 5, 2016Assignee: QUALCOMM IncorporatedInventors: Udara Charman Fernando, Supratik Bhattacharjee, Valentin Alexandru Gheorghiu, Gene Fong

Publication number: 20160044549Abstract: Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.Type: ApplicationFiled: October 19, 2015Publication date: February 11, 2016Inventors: Tingfang JI, Peter GAAL, Gene FONG, KapiI BHATTAD, Yongbin WEI

Patent number: 8934387Abstract: A BT receiver RF front end receives RF energy in a sequence of BT scan windows. Throughout a scan window, the front end is tuned to one hop frequency. Before and after the window the front end is in a disabled state. A WLAN energy detector processes an output of the front end during the window and determines whether more than a predetermined amount of RF energy was received onto the front end during the window. A BT baseband processor attempts to demodulate the output of the front end. If the WLAN energy detector determines that the predetermined amount of RF energy was received and if a BT signal could not be demodulated, then a WLAN wake-up signal is asserted, thereby causing a WLAN transceiver to be powered up to receive WLAN signals. BT scan intervals are varied in duration to facilitate a BT scan window overlapping a WLAN beacon.Type: GrantFiled: May 5, 2011Date of Patent: January 13, 2015Assignee: QUALCOMM IncorporatedInventors: Jianqiang He, Kai Bai, Gene Fong

Publication number: 20130016765Abstract: Techniques for windowing a transmission are disclosed herein. In one aspect of the disclosure, the length of a window used for windowing may be configurable and determined for a transmission based on a configuration of the transmission. The configuration of the transmission may be determined based on one or more parameters such as a system bandwidth, a bandwidth assigned for the transmission, the location of the assigned bandwidth within the system bandwidth, a modulation type used for the transmission, etc. In another aspect of the disclosure, a preferred length for a window may be determined for each of a number of possible configurations of a transmission. Different possible window lengths may be evaluated for each possible configuration based on one or more performance metrics. For each configuration, a window length that can provide the best performance for that configuration may be selected as a preferred window length for that configuration.Type: ApplicationFiled: June 29, 2012Publication date: January 17, 2013Applicant: QUALCOMM INCORPORATEDInventors: Jong Hyeon Park, Brian Clarke Banister, Zhu Ji, Gene Fong, Raghu Narayan Challa

Publication number: 20120243447Abstract: Certain aspects of the present disclosure provide a dual antenna distributed radio frequency front end (RFFE). RFFE topologies described herein may provide lower insertion loss (IL), reduced emission mask, decreased power consumption, and/or lower noise figure (NF) compared to conventional RFFE topologies. One example apparatus for wireless communications generally includes first and second power amplifiers (PAs) for amplifying signals for transmission, a transmit antenna for transmitting the amplified signals, a receive antenna for receiving other signals to be processed in a receive path, and a first transmit filter configured to filter the amplified signals from the first PA before amplification by the second PA. For certain aspects, a divided inter-stage filter providing overlapping frequency bands may be utilized. For certain aspects, the RFFE may support frequency-division duplexing (FDD)/TDD (time-division duplexing) coexistence, including support for FDD/TDD MIMO (multiple input multiple output).Type: ApplicationFiled: March 19, 2012Publication date: September 27, 2012Applicant: QUAL COMM IncorporatedInventors: Haim M.
