Publication number: 20220312436Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.Type: ApplicationFiled: October 22, 2020Publication date: September 29, 2022Inventors: Weidong YANG, Jie CUI, Seyed Ali Akbar FAKOORIAN, Amir Aminzadeh GOHARI, Hong HE, Haijing HU, Chao JIN, Ruoheng LIU, Huaning NIU, Oghenekome OTERI, Ralf ROSSBACH, Haitong SUN, Yang TANG, Sarma V.

Publication number: 20220312405Abstract: A user equipment (UE) may report physical uplink control channel (PUCCH) group capabilities to a network. The UE receives a request from a network for radio access capability information and reports whether a single PUCCH group having a plurality of component carriers (CC) using more than two numerologies across the CCs is supported. The UE may also receive a request from a network for radio access capability information and report whether a PUCCH group having a plurality of CC across multiple frequency bands is supported, wherein the report is configured per band combination (BC). The UE may also receive a request from a network for radio access capability information and report support for a PUCCH location configuration for a PUCCH group having a plurality of CC across multiple frequency bands, the PUCCH location configuration indicating which bands in a band combination (BC) may be used for the PUCCH.Type: ApplicationFiled: October 13, 2020Publication date: September 29, 2022Inventors: Haitong SUN, Amir Aminzadeh GOHARI, Amir FARAJIDANA, Dawei ZHANG, Hong HE, Leilei SONG, Mariam MOTAMED, Ruoheng LIU, Wei ZENG, Wenshu ZHANG, Yushu ZHANG

Patent number: 11374677Abstract: Methods, systems, and devices for wireless communications are described. More specifically, the methods, systems, and devices support extending capability signaling to support higher modulation order baseband capability, such as higher order quadrature amplitude modulation (QAM), for example, 1024QAM. By way of example, a user equipment (UE) may transmit UE capability information to a base station (e.g., eNodeB (eNB), next-generation NodeB ((gNB)) in a connection establishment procedure. The UE capability information may include a UE category identifier and a baseband capability parameter. The baseband capability parameter may indicate a scaling factor for a first modulation order of a plurality of available modulation orders. The UE may communicate with the base station over multiple layers using corresponding modulation orders for the multiple layers.Type: GrantFiled: March 31, 2020Date of Patent: June 28, 2022Assignee: QUALCOMM IncorporatedInventors: Wenshu Zhang, Amir Farajidana, Timothy Paul Pals, Alberto Rico Alvarino, Honey Kakkar, Parastoo Kheirkhah, Nitin Pant, Umesh Phuyal, Venkata Naga Aishwarya Reddy Kasa, Shashank Maiya

Patent number: 11297490Abstract: Aspects are provided which allow an apparatus to efficiently indicate downgraded band combinations associated with carrier aggregation (CA) to a base station, in which one or more UE capabilities such as the DL MIMO of certain supported band combinations may be downgraded in exchange for other UE capabilities such as FD-MIMO and 256/1024QAM. The apparatus, which may be a UE, receives a request from a base station for information associated with downgraded band combinations and for information corresponding to at least one UE capability associated with each of the downgraded band combinations. After receiving the request, the UE sends, to the base station, information indicating the downgraded band combinations and the at least one UE capability. The UE may thus report downgraded band combinations for a subset of supported band combinations as requested by the base station, thereby minimizing capability reporting of the UE.Type: GrantFiled: February 21, 2020Date of Patent: April 5, 2022Assignee: QUALCOMM IncorporatedInventors: Timothy Paul Pals, Alberto Rico Alvarino, Amir Farajidana, Honey Kakkar, Parastoo Kheirkhah, Nitin Pant, Umesh Phuyal, Wenshu Zhang

Patent number: 10985878Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations may transmit downlink transmissions in transmission time intervals (TTIs) or short TTIs (sTTIs). The base stations and user equipment (UE) receiving the downlink transmissions may be configured to determine a transport block size, soft channel bit buffer size, or rate matching based on the sTTI. The transport block size may be selected based on a scaling factor associated with signaling overhead or a type, length, or index of sTTI, or based on an sTTI transport block size table. The buffer size may be selected based on scaling or not scaling a buffer size value associated with a TTI. UEs may handle receiving retransmissions of downlink transmissions in different length TTIs, and base stations may select channel quality indicator-to-modulation and coding scheme mappings on an sTTI-by-sTTI basis.Type: GrantFiled: October 7, 2018Date of Patent: April 20, 2021Assignee: QUALCOMM IncorporatedInventors: Wenshu Zhang, Amir Farajidana, Seyedkianoush Hosseini, Shashank Maiya
