A method for allocating time and frequency resources for at least one data transmission via a fast fading frequency selective channel between an access point (110, 111) of a wireless telecommunications network and at least one communication device located in at least one respective moving conveyance moving on a path, the method comprising: - obtaining long-term signal-plus-interference to noise ratio information for a set of time and frequency resources potentially concerned by the time and frequency resources allocation; - obtaining at least one frequency correlation profile of the fast fading frequency selective channel, which is representative of a correlation between the frequencies of the time and frequency resources potentially concerned by the allocation; - obtaining at least one time correlation profile of the fast fading frequency selective channel, which is representative of a correlation between the time slots of the time and frequency resources potentially concerned by the allocation; - computing figures of merit for potential sequences of time and frequency resources among the set of time and frequency resources, by combining, into one instantaneous signal-plus-interference to noise ratio covariance matrix for each moving conveyance, the time correlation profile, the frequency correlation profile and the long-term signal-plus-interference to noise ratio information, wherein each figure of merit is: • either a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected probability of success of said data transmission(s); or, • a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected throughput of said data transmission(s); - selecting a sequence of time and frequency resources that provides a figure of merit, among the computed figures of merit, that expects reaching a target quality of service for said data transmission(s) or that is the best figure or merit; and allowing said data transmission(s) via the selected sequence of time and frequency resources. - obtaining long-term signal-plus-interference to noise ratio information for a set of time and frequency resources potentially concerned by the time and frequency resources allocation; - obtaining at least one frequency correlation profile of the fast fading frequency selective channel, which is representative of a correlation between the frequencies of the time and frequency resources potentially concerned by the allocation; - obtaining at least one time correlation profile of the fast fading frequency selective channel, which is representative of a correlation between the time slots of the time and frequency resources potentially concerned by the allocation; - computing figures of merit for potential sequences of time and frequency resources among the set of time and frequency resources, by combining, into one instantaneous signal-plus-interference to noise ratio covariance matrix for each moving conveyance, the time correlation profile, the frequency correlation profile and the long-term signal-plus-interference to noise ratio information, wherein each figure of merit is: • either a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected probability of success of said data transmission(s); or, • a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected throughput of said data transmission(s); • either a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected probability of success of said data transmission(s); or, • a result of a function to which the instantaneous signal-plus-interference to noise ratio covariance matrix is input and which represents an expected throughput of said data transmission(s); - selecting a sequence of time and frequency resources that provides a figure of merit, among the computed figures of merit, that expects reaching a target quality of service for said data transmission(s) or that is the best figure or merit; and allowing said data transmission(s) via the selected sequence of time and frequency resources.
