Embodiment Construction

[0056] This article discusses techniques for providing an adaptive trading area environment. For example, a closed-loop transaction system may adjust parameters that affect transaction performance (eg, the receipt and processing of wireless transaction requests). Parameters can be adjusted to improve transaction performance, taking into account the adverse effects of parameter adjustment on other signaling. For example, the user equipment may be provided with information about parameters of the radio frequency transaction area. These parameters may affect characteristics such as: area size (and location) and shape; rate, power, minimum and / or maximum number of transaction requests sent by user equipment in the area. The parameters may change over time and may be provided to the user equipment by base stations whose communication range includes the transaction area. At least a portion of a transaction message that explicitly and / or implicitly requests a transaction may be enc...

Abstract

A method of controlling a radio frequency (RF) transaction area includes determining a value of a characteristic associated with an ability of a roadside device associated with an RF transaction to acquire information from a user equipment (UE) in the RF transaction area; based on the value of the characteristic, determining a parameter value influencing the capability of the roadside device to acquire information from the UE in the RF transaction area; and transmitting the parameter value to a UE to affect message transmission from the UE to a roadside device.

Description

Background technique [0001] The connected-vehicle RF environment is a spectrum-constrained, bandwidth-constrained resource. For example, the available spectrum may be around 20MHz to less than 6GHz. This spectrum is likely to be used more and more as more RF-based interconnected vehicle (eg, vehicle-to-everything (V2X)) transactions take place. This spectrum or one or more other spectrums may have similar constraints and may be used for vehicle applications or other applications, eg, pedestrian-to-everything (P2X) applications. Also, some radio protocols do not provide reliable unicast performance. Systems that rely on V2X transactions, such as vehicle charging systems, may miss vehicles crossing the transaction execution area. For example, when a vehicle enters a transaction execution area and sends a message to a roadside equipment (RSE) (also known as a roadside unit (RSU)), the RSE may not be able to receive or process the message, and may therefore miss the expected tr...
