Patent number: 11659446Abstract: Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.Type: GrantFiled: November 24, 2020Date of Patent: May 23, 2023Assignee: Parallel Wireless, Inc.Inventors: Steven Paul Papa, Rajesh Kumar Mishra, Kaitki Agarwal, Sridhar Donepudi, Sumit Garg, Kartik Shashikant Raval, Prashanth Rao

Patent number: 11601916Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure the reference signal received power (RSRP) of reference signals from other UEs in a time window and exclude resources of transmissions with a measurement which is above RSRP threshold. In some cases, not enough resources are identified, and the UE may increase the RSRP and search for resources again, however the UE may only increase the RSRP until a stop RSRP limit is reached. The UE may increase the RSRP based on an absolute value or a factor of an incremental power value. Once the stop RSRP threshold is reached, the UE may modify the size of the time window, shift the time window, or reduce the number of retransmission of the sidelink message to search for resources for the sidelink message.Type: GrantFiled: November 5, 2020Date of Patent: March 7, 2023Assignee: Qualcomm IncorporatedInventors: Kapil Gulati, Tien Viet Nguyen, Gabi Sarkis, Sudhir Kumar Baghel

Patent number: 11570659Abstract: Aspects of the present disclosure provide techniques for search space channel sensing in sidelink communication between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications. Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels/resources) for transmission and reception of sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) between the PLC from the one or more SAs. Thus, in some instances, the UE may perform congestion control metrics for a one or more search spaces in which the UE may transmit sidelink communications. The congestion control metrics that may be limited to the search space may preserve UE resources that would otherwise need to be expended to perform channel sensing on an entire resource pool prior to initiating sidelink communication.Type: GrantFiled: December 18, 2020Date of Patent: January 31, 2023Assignee: QUALCOMM IncorporatedInventors: Xiaojie Wang, Jing Sun, Piyush Gupta
