摘要翻译：
我们考虑一个能量收集发射机向接收机发送关于它观察到的物理现象的状态更新。与现有文献不同，我们考虑的是状态更新携带关于独立消息的信息的场景。发送器将此消息编码为状态更新的定时。接收器需要提取这个编码信息，以及更新观察到的现象的状态。因此，状态更新的时间决定了信息的时间（AoI）和消息速率（rate）。我们研究了可实现的消息速率和可实现的平均AOI之间的折衷。我们提出了几种可实现的方案，并比较了它们的速率-AOI性能。

英文摘要：
  We consider an energy harvesting transmitter sending status updates regarding a physical phenomenon it observes to a receiver. Different from the existing literature, we consider a scenario where the status updates carry information about an independent message. The transmitter encodes this message into the timings of the status updates. The receiver needs to extract this encoded information, as well as update the status of the observed phenomenon. The timings of the status updates, therefore, determine both the age of information (AoI) and the message rate (rate). We study the tradeoff between the achievable message rate and the achievable average AoI. We propose several achievable schemes and compare their rate-AoI performances.
