Abstract

Various aspects of the present disclosure relate to methods and systems for configuring ambient IoT (AIoT) devices to transmit different types of data traffic. The methods and systems establish procedures (e.g., messaging flows) for configuring AIoT devices to perform device-originated autonomous (DO-A) type data transmissions, control the prioritization (e.g., load or access attempts) of DO-A type data transmission, introduce CBRA resource allocations and selections for DO-A type data transmissions, and identifies various methods for transmitting DO-A data.

Description

TECHNICAL FIELD The present disclosure relates to wireless communications, and more specifically to autonomous transmission for ambient Internet of Things (AIoT) devices. BACKGROUND A wireless communications system may include one or multiple network communication devices, which may be otherwise knowns as network equipment (NE), supporting wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers, or the like)). Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)). Ambient power-enabled devices, such as Internet of Things (IoT) devices, or AIoT devices, include battery-less devices that have limited storage capabilities (e.g., via capacitors) or other capability restrictions. In some cases, these ambient power-enabled devices may store energy by harvesting energy from the environment, such as via radio waves, light, heat, motion, and other energy/power sources available to the devices. SUMMARY An article “a” before an element is unrestricted and understood to refer to “at least one” of those elements or “one or more” of those elements. The terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” or “one or both of”) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. Further, as used herein, including in the claims, a “set” may include one or more elements. The present disclosure relates to methods, apparatuses, and systems that support wireless communication for AIoT devices, including autonomous device-originated communication (e.g., data transmission, data reception) for AIoT devices. A reader device for wireless communication is described. The reader device may be configured to, capable of, or operable to perform one or more operations as described herein. For example, the reader device may comprise at least one memory and at least one processor coupled with the at least one memory and configured to cause the reader device to transmit, to an IoT device, a first message comprising a set of one or more parameters for autonomous data transmission, and receive, from the IoT device, a second message based at least in part on the transmitted first message. A processor for wireless communication is described. The processor may be configured to, capable of, or operable to perform one or more operations as described herein. For example, the processor may comprise at least one controller coupled with at least one memory and configured to cause the processor to transmit, to an IoT device, a first message comprising a set of one or more parameters for autonomous data transmission, and receive, from the IoT device, a second message based at least in part on the transmitted first message. A method performed or performable by a reader device is described. The method may comprise transmitting, to an IoT device, a first message comprising a set of one or more parameters for autonomous data transmission, and receiving, from the IoT device, a second message based at least in part on the transmitted first message. In some implementations of the reader device, processor, and method described herein, the set of one or more parameters comprise a set of one or more values, and wherein each value indicates a corresponding priority associated with channel access for the IoT device during a contention-based random access (CBRA) procedure. In some implementations of the reader device, processor, and method described herein, the set of one or more values is based at least in part on a type of data for autonomous data transmission.
