Patent number: 12284591Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.Type: GrantFiled: January 8, 2021Date of Patent: April 22, 2025Assignee: QUALCOMM IncorporatedInventors: Konstantinos Dimou, Piyush Gupta, Kapil Gulati, Junyi Li, Jingyuan Liu, Alexander Leonidov, Sony Akkarakaran, Wooseok Nam, Yan Zhou, Ozge Koymen, Tao Luo

Patent number: 12279251Abstract: Methods, systems, and devices for wireless communications are described for improving sidelink communication reliability. In some examples, a user equipment (UE) may map allocated sidelink resources from a logical domain to a physical domain, where the mapped resources may include greater frequency diversity in the physical domain A frequency range of a sidelink control channel or of a sidelink data channel may be greater in the physical domain than in the logical domain after the mapping. In some examples, sidelink communications may be associated with an aggregation factor that represents a number of repetitions of a sidelink communication. In this example, a UE may repeat a sidelink communication within a contention-based resource pool a number of times before receiving feedback in order to increase communication reliability. A first UE may communicate a sidelink communication with a second UE using a resource mapping or repetitions of the sidelink communication.Type: GrantFiled: December 15, 2023Date of Patent: April 15, 2025Assignee: QUALCOMM IncorporatedInventors: Xiaojie Wang, Piyush Gupta, Jing Sun, Lik Hang Silas Fong

Patent number: 12273883Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications in order to minimize the number of subchannels that a receiver (e.g., PLC or SA) may need to blind decode. More particularly, the search space is configurable based on a hashing function that is based in part on a portion of the resources (e.g., PLC resources) that have been allocated or reserved for sidelink communication within the PLC subnetwork (or PLC group) from the sidelink resource pool available to a plurality of PLCs in a network. By limiting the search space to a subset of resources that are specific to the PLC subnetwork or group, the need for the SA or PLC to perform blind decoding of sidelink control information (SCI) may be further reduced.Type: GrantFiled: July 27, 2021Date of Patent: April 8, 2025Assignee: QUALCOMM IncorporatedInventors: Xiaojie Wang, Jing Sun, Piyush Gupta, Xiaoxia Zhang, Lik Hang Silas Fong
