Publication number: 20240098485Abstract: The techniques described herein may provide for sub-slot based physical uplink shared channel (PUSCH) repetition (i.e., back-to-back PUSCH repetition within a slot) according to user equipment (UE) capability. A UE may employ uplink data repetition capability reporting for base station scheduling of uplink data repetition and base station management of the number of transport blocks (TBs) that a UE supports (e.g., processes and transmits for uplink) on a per-slot basis. According to the techniques described herein, a UE may indicate whether it supports mini-slot repetition (e.g., for ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), or both) via an uplink data repetition capability report. The uplink data repetition capability report may further indicate a maximum number of supported repetitions per TB, a number of supported TBs per slot, etc., such that a base station may configure or schedule PUSCH repetition based on the UE's reported capability.Type: ApplicationFiled: July 3, 2023Publication date: March 21, 2024Inventors: Kianoush HOSSEINI, Enoch Shiao-Kuang LU, Peter GAAL, Aamod KHANDEKAR, Seyed Ali Akbar FAKOORIAN

Patent number: 11916671Abstract: Methods, systems, and devices for interleaved mapping are described. In some implementations, a transmitting device identifies a set of virtual resource blocks (VRBs) corresponding to at least one code block to be transmitted to a receiving device. The transmitting device may determine that a quantity of VRBs to be transmitted to the receiving device is different than a quantity of entries within a regular interleaving matrix. Thus, the transmitting device may map each of the VRBs to a physical resource block (PRB) according to an irregular interleaving matrix to generate at least one interleaved code block. The transmitting device may transmit the interleaved code block to the receiving device. The receiving device may receive the interleaved code block and identify the PRBs associated with the interleaved code block. The receiving device may map each PRB within the interleaved code block to a VRB according to an irregular deinterleaving matrix.Type: GrantFiled: September 16, 2020Date of Patent: February 27, 2024Assignee: QUALCOMM IncorporatedInventors: Hongsan Sheng, Subramanya P. N. Rao, Aamod Khandekar, Yang Sun, Srujana Ellanki, Navaneet Reddy Danda

Publication number: 20240049198Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.Type: ApplicationFiled: October 18, 2023Publication date: February 8, 2024Inventors: Wanshi CHEN, Kianoush HOSSEINI, Peter GAAL, Srinivas YERRAMALLI, Hao XU, Jing SUN, Shimman Arvind PATEL, Aamod KHANDEKAR

Patent number: 11882554Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.Type: GrantFiled: June 23, 2020Date of Patent: January 23, 2024Assignee: QUALCOMM IncorporatedInventors: Kapil Gulati, Aamod Khandekar, Shailesh Patil, Shuanshuan Wu, Tien Viet Nguyen, Sudhir Kumar Baghel, Arjun Bharadwaj
