Patent number: 11140706Abstract: A grant may allocate resources for an uplink transmission by a user equipment (UE) in a system using beamforming, where the resources may be used by the UE to transmit data or control information during a time that a base station is listening in a certain receive beam direction. A UE may be in communication with a base station using beamformed transmissions, and the base station may send a resource grant to the UE for uplink transmissions that correspond to a receive beam direction of a beamsweeping operation. The UE may then transmit data and/or uplink control information to the base station according to the resource grant and when the base station is listening in the corresponding direction. In some examples, the UE may send the uplink transmission to the serving base station, and transmit a random access channel to another base station based on the beamsweeping operation.Type: GrantFiled: January 30, 2018Date of Patent: October 5, 2021Assignee: QUALCOMM IncorporatedInventors: Sony Akkarakaran, Tao Luo, Sumeeth Nagaraja, Makesh Pravin John Wilson, Kaushik Chakraborty, Xiao feng Wang, Shengbo Chen, Wooseok Nam

Patent number: 11082096Abstract: A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semi-static signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. These feedback techniques may be used to provide feedback for uplink or downlink transmissions.Type: GrantFiled: December 27, 2019Date of Patent: August 3, 2021Assignee: QUALCOMM IncorporatedInventors: Sony Akkarakaran, Tao Luo, Makesh Pravin John Wilson, Kaushik Chakraborty, Wooseok Nam, Shengbo Chen

Publication number: 20210135804Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted).Type: ApplicationFiled: November 6, 2020Publication date: May 6, 2021Inventors: Sumeeth Nagaraja, Tao Luo, Sony Akkarakaran, Makesh Pravin John Wilson, Xiao Feng Wang, Juan Montojo, Shengbo Chen, Wooseok Nam

Publication number: 20210127428Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support uplink random access channel (RACH) transmissions on multiple beams and over multiple component carriers (CCs). A wireless device may transmit a random access preamble to a base station in a first RACH transmission, which may indicate a set of CCs over which the base station may respond with a random access response (RAR) in a second RACH transmission.

The wireless device may also indicate a beam index and/or time-frequency resources associated with beams and/or CCs used for such cell acquisition transmissions. In other examples, the base station may indicate resources (e.g., via a handover command or RACH command) for wireless device scheduling request and/or beam-failure recovery request transmission.Type: ApplicationFiled: January 6, 2021Publication date: April 29, 2021Inventors: Sony Akkarakaran, Tao Luo, Makesh Pravin John Wilson, Sumeeth Nagaraja, Xiao Feng Wang, Kaushik Chakraborty, Wooseok Nam, Shengbo Chen, Juan Montojo

Patent number: 10972987Abstract: A user equipment (UE) may transmit a power headroom report in response to changing beamforming parameters. The UE may autonomously change beamforming parameters from a preconfigured set of beams or receive a command to change beamforming parameters for transmissions on a new beam. The UE may determine a power headroom applicable to a transmission from the UE on the new beam. The UE may transmit, in response to the command, a power headroom report based on the power headroom using resources configured for the power headroom report. For example, the power headroom report may be multiplexed with an uplink transmission from the UE using the new beam. In an aspect, the UE may select a scheduled transmission during a time period after the command is implemented as the uplink transmission. For example, the power headroom report may be transmitted as a physical layer transmission or as a MAC-CE transmission.Type: GrantFiled: September 24, 2018Date of Patent: April 6, 2021Assignee: Qualcomm IncorporatedInventors: Sony Akkarakaran, Tao Luo, Juan Montojo, Xiao Feng Wang, Shengbo Chen, Sumeeth Nagaraja, Makesh Pravin John Wilson
