Publication number: 20240023115Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first carrier associated with a first radio access technology, at least a first uplink grant from a base station. The UE may implement one or more backoff schemes. For example, the UE may transmit, using resources indicated by at least the first uplink grant, an uplink message based on a temperature of one or more components of the UE satisfying a threshold, the uplink message including a transport block (TB) indicating data, a buffer status report (BSR) associated with the data, one or more padding bytes different from the data, or any combination thereof. The UE may monitor for at least a second uplink grant from the base station during a first time period based on transmitting the uplink message.Type: ApplicationFiled: July 26, 2023Publication date: January 18, 2024Inventors: Mahbod GHELICHI, James Francis GEEKIE, Arnaud MEYLAN, Sivaram Srivenkata PALAKODETY, Bao Vinh NGUYEN, Michel CHAUVIN

Publication number: 20230389012Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration. The UE may transmit, via a scheduling request resource of a second logical channel that has a valid scheduling request configuration, a scheduling request for resources to transmit the data buffered for transmission via the first logical channel. Numerous other aspects are described.Type: ApplicationFiled: December 18, 2020Publication date: November 30, 2023Inventors: Krishna Chaitanya MUKKERA, Ambarish TRIPATHI, Peng WU, Zhibin DANG, Bao Vinh NGUYEN, Shailesh MAHESHWARI

Patent number: 11617189Abstract: A method of wireless communication by a user equipment (UE) includes receiving a number of uplink grants from a base station. The method further includes estimating a payload size for data to be transmitted from a UE buffer for a number of logical channels. The payload size corresponds to a sum of a number of data bytes to be transmitted and an amount of overhead bytes to be transmitted. The method still further includes determining a subset of the number of uplink grants to use for uplink transmission based on reducing a total padding size associated with transmitting the payload size, for each combination of the number of uplink grants. The method also includes transmitting the data from the UE buffer within a number of transport blocks, to the base station. The number of transport blocks corresponds to the subset of the number of uplink grants.Type: GrantFiled: March 24, 2021Date of Patent: March 28, 2023Assignee: QUALCOMM IncorporatedInventors: Michel Evan Chauvin, Arnaud Meylan, Bao Vinh Nguyen, Peng Wu

Publication number: 20210282150Abstract: A UE employing carrier aggregation receives an uplink grant from a wireless communication system base station for each of a plurality of Physical Uplink Shared CHannel (PUSCH) component carriers. The UE orders each PUSCH component carrier for transmission based at least in part on the uplink grant. The UE ranks logical channels for uplink transmission; and then builds transport blocks comprising data of higher ranked logical channels on higher ordered component carriers. The UE can then transmit the transport blocks across the component carriers to the base station.Type: ApplicationFiled: March 4, 2021Publication date: September 9, 2021Inventors: Krishna Chaitanya MUKKERA, Shailesh MAHESHWARI, Bao Vinh NGUYEN, Dinesh Kumar DEVINENI, Tom CHIN

Patent number: 10805828Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.Type: GrantFiled: July 11, 2019Date of Patent: October 13, 2020Assignee: QUALCOMM IncorporatedInventors: Seyed Ali Ahmadzadeh, Srinivasan Balasubramanian, Shailesh Maheshwari, Ashwini Raina, Vishal Dalmiya, Rohit Kapoor, Leena Zacharias, Bao Vinh Nguyen

Patent number: 10750520Abstract: Techniques and apparatus for implementing a radio link control (RLC) layer and/or packet data convergence protocol (PDCP) layer window advance with holes (e.g., one or more missing packets) are provided. One technique includes generating a sequence of packets for transmission to an apparatus. A determination of whether to request the apparatus to at least temporarily ignore missing packets from the sequence is made based on one or more criteria. A message with an indication of the determination is transmitted to the apparatus. The apparatus may receive the sequence of packets, detect missing packets in the sequence, and process the sequence of packets in accordance with the indication in the received message.Type: GrantFiled: March 6, 2018Date of Patent: August 18, 2020Assignee: QUALCOMM IncorporatedInventors: Yue Yang, Aziz Gholmieh, Shailesh Maheshwari, Srinivasan Balasubramanian, Vishal Dalmiya, Bao Vinh Nguyen

Patent number: 10686560Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.Type: GrantFiled: June 22, 2015Date of Patent: June 16, 2020Assignee: QUALCOMM IncorporatedInventors: Gang Andy Xiao, Ashwini Raina, Shailesh Maheshwari, Rudhir Upretee, Mohan Krishna Gowda, Bao Vinh Nguyen, Deepak Krishnamoorthi, Prasad Kadiri, Pavan Kaivaram, Chintan Shirish Shah, Meric Uzunoglu, Aziz Gholmieh

Patent number: 10432761Abstract: Techniques are described for wireless communication. One method includes receiving, at a medium access control (MAC) entity, protocol data units (PDUs) corresponding to one or more Internet protocol (IP) flows, routing the PDUs from the MAC entity to respective radio link control (RLC) entities based on a logical channel prioritization, and forwarding the PDUs from respective RLC entities to one or more packet data convergence protocol (PDCP) entities mapped to each RLC entity. Another method includes receiving, at a protocol layer entity above an RLC layer of a transmitting device, a PDU, labeling the PDU with a unique PDCP instance identifier packet, and passing the PDU to a protocol layer entity below the PDCP layer of the transmitting device.Type: GrantFiled: July 14, 2017Date of Patent: October 1, 2019Assignee: QUALCOMM IncorporatedInventors: Yue Yang, Yu-Ting Yu, Aziz Gholmieh, Leena Zacharias, Shailesh Maheshwari, Vishal Dalmiya, Bao Vinh Nguyen, Gavin Bernard Horn
