Publication number: 20250151097Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive encoded data from a network entity. The UE may decode the data in accordance with a size of the circular buffer. The UE, the network entity, or both may determine the size of the circular buffer based on a capability of the UE. In some examples, the size of the circular buffer may be associated with one or more limits for performing the decoding operation, including a limit for a quantity of encoded bits the UE can process during a sliding window. For example, the limits may consider any combination of a quantity of encoded bits or information bits that the UE may write to or write from a memory of the UE. In some cases, the limits may consider multiple bandwidth parts, multiple component carriers, or any combination thereof.Type: ApplicationFiled: November 6, 2023Publication date: May 8, 2025Inventors: Mostafa KHOSHNEVISAN, Kianoush HOSSEINI, Jing SUN, Jing JIANG

Patent number: 12295035Abstract: Wireless communications systems and methods related to use of cyclic prefix (CP) extensions for channel occupancy time (COT) sharing among sidelink user equipment devices (UEs) are provided. A first UE detects a first sidelink transmission in a COT, the COT for sharing with multiple sidelink UEs including the first sidelink UE. The first UE may determine a CP extension length for transmitting a second sidelink transmission after the first sidelink transmission, where a gap duration between the first sidelink transmission and the second sidelink transmission satisfies a listen-before-talk (LBT) gap time threshold. The first UE may apply a CP extension having the CP extension length to the second sidelink transmission and transmit, to a second sidelink UE, the second sidelink transmission with the CP extension.Type: GrantFiled: April 16, 2020Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Jing Sun, Xiaoxia Zhang, Changlong Xu, Chih-Hao Liu, Ozcan Ozturk, Yisheng Xue

Patent number: 12295004Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.Type: GrantFiled: December 20, 2021Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Mostafa Khoshnevisan, Xiaoxia Zhang, Wei Yang, Jing Sun

Patent number: 12294979Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.Type: GrantFiled: December 15, 2023Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Xiaojie Wang, Piyush Gupta, Jing Sun

Patent number: 12294997Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.Type: GrantFiled: November 30, 2021Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Chih-Hao Liu, Jing Sun, Yisheng Xue, Xiaoxia Zhang

Patent number: 12295033Abstract: This disclosure provides systems, methods, and devices for wireless communication that support management of network-configured sensing bandwidths in a wireless communication system. In particular aspects, a network configures a sensing bandwidth, and the sensing bandwidth configuration is signaled to a contending node.

Aspects of this disclosure provide various techniques for signaling the configuration of the sensing bandwidth to the contending node.Type: GrantFiled: March 31, 2022Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Vinay Chande, Jing Sun, Arumugam Chendamarai Kannan, Giovanni Chisci, Xiaoxia Zhang, Tao Luo

Patent number: 12295012Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in an unlicensed spectrum (e.g., a shared radio frequency spectrum band). As such, the UE may determine a codebook size for transmitting hybrid access request (HARQ) acknowledgement (ACK) feedback with respect to the unlicensed spectrum. Accordingly, the UE may base the HARQ ACK codebook size on a number of HARQ processes with which the UE has been configured. Additionally or alternatively, the UE may base the HARQ ACK codebook size on a number and/or duration of downlink channel monitoring occasions indicated by the base station. In some cases, the UE may base the HARQ ACK codebook size on a combination of the techniques described herein.Type: GrantFiled: February 5, 2024Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Xiaoxia Zhang, Zhifei Fan, Kapil Bhattad, Jing Sun, Tamer Kadous, Srinivas Yerramalli

Patent number: 12295043Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.Type: GrantFiled: September 7, 2023Date of Patent: May 6, 2025Assignee: QUALCOMM IncorporatedInventors: Xiaoxia Zhang, Jing Sun, Sony Akkarakaran, Muhammad Nazmul Islam, Tao Luo
