I am trying to think about the possible sources of noises and trying to acquire the basic channel model in 6G. Would you please advise if there are any models available?
Sir the following could help:

Dear Rahul,
There are basic types of communication channels which will be also valid for any generation. The additive white noise model, the Rayleigh channel, the Rician channel model for multi path fading.
Then comes the interference from the nearby sources.
When you have the network configuration and the activity of each node you can then get then determine the interference.
Normally the interference is avoided when building the networks such that it must be minimized by the multiple accessing techniques so that the transmissions must be orthogonal to each other.
There may be other factors as a specific nature of the configuration of the 6G networks. One has to define it first to model the channel.
Best wishes
Dear Rahul:
It depends on the operating frequency and wireless environment you desire, whether you are considering 4G, 5G, or 6G applications.
You can try the given channel models based on the above conditions first, unless you are considering brand new frequency bands (e.g., Tera Hz) in which further discussions are required.
As to noise, the additive noise exists in nature and we only concern the noise power levels.
BRs,
Sir, I came across the following which would be helpful:

Dear Rahul,
6G will most likely operate in the teraHertz band. Behavior of the TeraHertz channel model is closely related to the optical communication channel model or even the mmWave band. MAybe you can try to look into the research papers about these.
From my reading thus far:
Few studies have indicated that THz transmission will have a crucial function to perform in the uplink as a LoS will not be a prerequisite. Hence, this condition may tilt the 6G technology into the Rayleigh channel model and drastically reduce the need for the Rician channel model.
Few studies have indicated that propagation characteristics of THz is subject to atmospheric conditions; therefore, absorptive and dispersive effects are seen, and climatic conditions change frequently and are, therefore, highly unpredictable. Thus, the channel modeling of THz band is relatively complex, and this band does not have any perfect channel model.
There are also few studies which have indicated a mixed channel model to be used for 6G.
