Publication number: 20170094545Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity.Type: ApplicationFiled: August 11, 2016Publication date: March 30, 2017Inventors: Parvathanathan Subrahmanya, Qiang Shen, Aamod Dinkar Khandekar, Mariam Motamed, Wanshi Chen, Hanfang Pan, Deepak Mathew

Patent number: 9565011Abstract: Techniques for supporting communication in dominant interference scenarios are described. In an aspect, communication in a dominant interference scenario may be supported with cross-subframe control. Different base stations may be allocated different subframes for sending control information. Each base station may send control messages in the subframes allocated to that base station. Different base stations may have different timelines for sending control messages due to their different allocated subframes. With cross-subframe control, control information (e.g., grants, acknowledgement, etc.) may be sent in a first subframe and may be applicable for data transmission in a second subframe, which may be a variable number of subframes from the first subframe. In another aspect, messages to mitigate interference may be sent on a physical downlink control channel (PDCCH).Type: GrantFiled: June 2, 2010Date of Patent: February 7, 2017Assignee: QUALCOMM IncorporatedInventors: Ravi Palanki, Aamod Dinkar Khandekar, Kapil Bhattad

Publication number: 20160360545Abstract: Providing for improved implementation of supplemental wireless nodes in a wireless base station deployment is described herein. By way of example, a donor base station is configured to send a schedule of data transmission to and from a set of UEs served by the base station, and further can provide the schedule and identifiers for the set of UEs to one or more wireless nodes serving the base station. Respective access channel measurements between respective UEs and respective wireless nodes can be forwarded to the base station, which in turn can identify optimal access channels for the set of UEs. Additionally, the donor base station can schedule multiple data transmissions on these access channels in a common transmission time slot, to achieve cell-splitting gains for the data transmissions. Range boosting, differential coding, and supplemental channel quality mechanisms are also provided for various wireless communication arrangements described herein.Type: ApplicationFiled: August 16, 2016Publication date: December 8, 2016Inventors: Aamod Dinkar Khandekar, Ravi Palanki, Alexei Yurievitch Gorokhov

Patent number: 9503929Abstract: Techniques for transmitting overload indicators over the air to UEs in neighbor cells are described. In one design, an overload indicator may be transmitted as a phase difference between at least one synchronization signal and a reference signal for a cell. In another design, an overload indicator may be transmitted as a phase difference between consecutive transmissions of at least one synchronization signal for a cell. In yet another design, an overload indicator may be transmitted by a cell on resources reserved for transmitting the overload indicator. In yet another design, an overload indicator may be transmitted by a cell on a low reuse channel or a broadcast channel. For all designs, a UE may receive overload indicators from neighbor cells, determine the loading of each neighbor cell based on the overload indicator for that cell, and control its operation based on the loading of the neighbor cells.Type: GrantFiled: March 16, 2015Date of Patent: November 22, 2016Assignee: QUALCOMM IncorporatedInventors: Ravi Palanki, Juan Montojo, Aamod Dinkar Khandekar, Tao Luo, Kapil Bhattad

Patent number: 9392621Abstract: Systems and methodologies are described that facilitate commanding a wireless device to transmit a random access channel (RACH) signal to measure communication parameters related thereto. The wireless device can transmit a RACH preamble upon receiving a command, and one or more parameters can be computed based at least in part on transmitting the command and/or receiving the RACH preamble, such as a round trip time, a received signal power, and/or the like. The one or more parameters can be communicated to the wireless device in a RACH response signal, and can be utilized by the wireless device. The wireless device can utilize the one or more parameters to estimate a distance for position determination, compute a path loss, and/or the like.Type: GrantFiled: June 22, 2010Date of Patent: July 12, 2016Assignee: QUALCOMM IncorporatedInventors: Raja Sekhar Bachu, Aamod Dinkar Khandekar

Publication number: 20160192317Abstract: Systems and methodologies are described that facilitate transmitting positioning reference signals (PRS) differently for passive distributed elements. PRSs for passive distributed elements can be transmitted over disparate resources than those utilized for PRSs at a related access point, using different symbol sequences, and/or the like. In this regard, wireless devices can differentiate between PRSs from access points and those from passive distributed elements, which can mitigate confusion for processes involving such RSs, such as position determining. Alternatively, passive distributed elements can refrain from transmitting PRSs, and a corresponding access point can indicate to wireless devices to only determine positioning based on PRSs. Thus, the wireless devices can utilize the PRSs transmitted from the access point (and not other reference signals transmitted from the passive distributed element) to determine a position.Type: ApplicationFiled: March 7, 2016Publication date: June 30, 2016Inventors: Aamod Dinkar Khandekar, Ravi Palanki, Ashwin Sampath, Naga Bhushan, Raja Sekhar Bachu

Patent number: 9295008Abstract: Techniques for mitigating interference in a wireless communication system are described. In one design, a sector may determine multiple fast other sector interference (OSI) indications for multiple subzones, with each subzone corresponding to a different portion of the system bandwidth. At least one report may be generated for the multiple OSI indications, with each report including at least one OSI indication for at least one subzone. Each report may be encoded to obtain code bits, which may then be mapped to a sequence of modulation symbols. A sequence of modulation symbols of zero values may be generated for each report with all OSI indications in the report set to zero to indicate lack of high interference in the corresponding subzones. This allows a report to be transmitted with zero power in a likely scenario. A regular OSI indication may also be determined for the system bandwidth and transmitted.Type: GrantFiled: March 29, 2013Date of Patent: March 22, 2016Assignee: QUALCOMM IncorporatedInventors: Alexei Yurievitch Gorohkov, Aamod Dinkar Khandekar, Jaber Mohammad Borran

Patent number: 9288760Abstract: A method and apparatus for controlling uplink transmit power with optimum delay is described. A transmit power control command may be received. A time slot of the transmit power control command may be determined. Based on the time slot, it may be determined to decode the transmit power control command, with a delay. The transmit power control command may be decoded, after the delay, using a transmit power control command decoding graph by determining a strength of the transmit power control command and plotting the strength on the transmit power control command decoding graph. The transmit power control command decoding graph may include regions. Decoding the transmit power control command, after the delay, may be based on a region associated with plotting the strength of the transmit power control command.Type: GrantFiled: June 12, 2013Date of Patent: March 15, 2016Assignee: QUALCOMM IncorporatedInventors: Insung Kang, Surendra Boppana, Aamod Dinkar Khandekar
