Patent number: 11838920Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message indicating a configured grant-small data transfer (CG-SDT) group that includes the UE. The CG-SDT group is associated with a downlink beam of the base station and one or more CG-SDT occasions. The UE may transmit, to the base station and within the one or more CG-SDT occasions, an uplink communication, using an uplink beam of the UE corresponding to a downlink beam of the UE, where the downlink beam of the UE is associated with the downlink beam of the base station used for transmitting at least one of the configuration message, a paging message, or a reference signal. Numerous other aspects are provided.Type: GrantFiled: July 28, 2021Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Jing Lei, Linhai He, Yongjun Kwak, Huilin Xu, Krishna Kiran Mukkavilli, Wanshi Chen, Hwan Joon Kwon, Tingfang Ji

Patent number: 11838916Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating a joint field for at least a first component carrier (CC) and a second CC of a carrier aggregation configuration. For example, the joint field may include a rate matching (RM) indication for the first CC and the second CC, a zero power channel state information reference signal (ZP-CSI-RS) indication for the first CC and the second CC, or both. In some cases, the RM indication may include a common RM resource (RMR) configuration applicable for both the first CC and the second CC or per-CC RMR configurations that indicate separate RMRs for each of the CCs. Additionally, the ZP-CSI-RS indication may include a set identifier that indicates a resource set for ZP-CSI-RS resources for both the first CC and the second CC.Type: GrantFiled: April 8, 2021Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Kazuki Takeda, Wanshi Chen, Peter Gaal, Xiaoxia Zhang, Huilin Xu, Mostafa Khoshnevisan, Tao Luo, Alberto Rico Alvarino

Patent number: 11838750Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission.Type: GrantFiled: October 25, 2022Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Wei Yang, Seyedkianoush Hosseini, Peter Gaal, Wanshi Chen, Yi Huang

Patent number: 11838893Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof.
