Patent number: 10098095Abstract: When a UE does not completely decode a packet transmitted from a base station, the UE may send ACK/NACK to the base station, upon which the base station may retransmit the packet based on the ACK/NACK. However, the ACK/NACK fails to provide the base station with information needed by the UE for completely decoding the packet. Accordingly, a method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a packet from a base station having a first MCS, determines information to provide to the base station, wherein the information comprises CQI relating to a channel condition and/or interference condition corresponding to time-frequency resources allocated for the received packet, and sends the information to the base station. Thereafter, the apparatus re-receives the packet from the base station, the re-received packet having a second MCS according to the information sent to the base station.Type: GrantFiled: May 20, 2013Date of Patent: October 9, 2018Assignee: QUALCOMM IncorporatedInventors: Raj Kumar Krishna Kumar, Kapil Bhattad, Dhananjay Ashok Gore, Yongbin Wei

Patent number: 9860033Abstract: Transmission schemes that can flexibly achieve the desired spatial multiplexing order, spatial diversity order, and channel estimation overhead order are described. For data transmission, the assigned subcarriers and spatial multiplexing order (M) for a receiver are determined, where M?1. For each assigned subcarrier, M virtual antennas are selected from among V virtual antennas formed with V columns of an orthonormal matrix, where V?M. V may be selected to achieve the desired spatial diversity order and channel estimation overhead order. Output symbols are mapped to the M virtual antennas selected for each assigned subcarrier by applying the orthonormal matrix. Pilot symbols are also mapped to the V virtual antennas. The mapped symbols are provided for transmission from T transmit antennas, where T?V. Transmission symbols are generated for the mapped symbols, e.g., based on OFDM or SC-FDMA. Different cyclic delays may be applied for the T transmit antennas to improve diversity.Type: GrantFiled: October 11, 2011Date of Patent: January 2, 2018Assignee: QUALCOMM IncorporatedInventors: Tamer Kadous, Aamod Khandekar, Dhananjay Ashok Gore, Alexei Gorokhov

Patent number: 9686800Abstract: Certain aspects of the present disclosure relate to techniques for reporting Channel Quality Indicator (CQI). In certain aspects, a User Equipment (UE) may schedule switch from at least a first set of zero or more antennas used by the UE, to at least one second set of zero or more antennas, wherein the first and second sets differ by at least one antenna.

Patent number: 9585156Abstract: When communications of a single radio access technology (RAT), or different radio access technologies in a proximate communication spectrum are operating at the same time, potential interference between devices may occur. To reduce the interference, the time division duplex (TDD) configuration of one or more conflicting device may be altered. For example, at the edge of a communication region, TDD configurations used by edge base stations to communicate with mobile devices may be set to reduce interference. As another example, communications of a first device may be altered so the first device schedules uplink communications when a second device also has uplink communications scheduled. Other configurations may also be implemented.Type: GrantFiled: November 8, 2012Date of Patent: February 28, 2017Assignee: QUALCOMM INCORPORATEDInventors: Kapil Bhattad, Dhananjay Ashok Gore, Tamer Adel Kadous, Ashok Mantravadi, Ahmed Sadek, Raj Kumar

Patent number: 9225488Abstract: A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel can be assigned to a predetermined number of sub-carriers within any frame. The assignment of a predetermined number of sub-carriers to the shared signaling channel establishes a fixed bandwidth overhead for the channel. The actual sub-carriers assigned to the channel can be varied periodically, and can vary according to a predetermined frequency hopping schedule. The amount of signal power allocated to the signaling channel can vary on a per symbol basis depending on the power requirements of the communication link. The shared signaling channel can direct each message carried on the channel to one or more access terminals. Unicast messages allow the channel power to be controlled per the needs of individual communication links.Type: GrantFiled: October 27, 2005Date of Patent: December 29, 2015Assignee: QUALCOMM IncorporatedInventors: Aamod Khandekar, Alexei Gorokhov, Dhananjay Ashok Gore, Edward Harrison Teague, Min Dong
