Event trigger for independent links

Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link.

METHOD AND SYSTEM OF PRECONDITIONING TRANSMITTED SIGNALS

Skywave propagation may be an effective communication method for providing low- latency data transmission between a transmitter and a receiver that are separated by a large distance. Although skywave propagation may reduce transmission times compared to other methods of communication such as fiber optic cables and satellite networks, distortion caused by ionospheric and other atmospheric conditions may cause a delay in processing the data signal as the data signal is unscrambled. In some instances, these delays may prove to be costly. For example, orders to buy and sell securities or other financial instruments in world markets, or even news pertinent to trading strategies, typically rely on communications links that carry data and instructions and delays of even a few milliseconds can cost millions of dollars. Therefore, it may be beneficial to have a communication system that that can reduce the effect of distortion caused by ionospheric conditions on skywave propagation.
