Patent number: 11910360Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.Type: GrantFiled: October 19, 2021Date of Patent: February 20, 2024Assignee: QUALCOMM IncorporatedInventors: Yisheng Xue, Xiaoxia Zhang, Chih-Hao Liu, Jing Sun, Tao Luo, Piyush Gupta, Juan Montojo, Peter Gaal, Sony Akkarakaran

Patent number: 11910408Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.Type: GrantFiled: June 25, 2021Date of Patent: February 20, 2024Assignee: QUALCOMM IncorporatedInventors: Xiaojie Wang, Piyush Gupta, Junyi Li
