Abstract: For performing K individual transmissions between an access point managing a cell of a wireless communications network to plural mobile terminals via time and frequency resources from amongst a predefined set of candidate time and frequency resources on a per frame period basis, one time and frequency resource being allocated to each one of the K individual transmissions in a considered frame period, the access point: obtains a frequency allocation descriptor F indicating which frequency resource is allocated in the considered frame period to each one of the K individual transmissions; obtains a frequency occurrence descriptor G indicating how many times each candidate frequency resource is used for performing the K individual transmissions in the considered frame period; signals the frequency occurrence descriptor G in said cell; and enables transmitting data for the K individual transmissions in accordance with the frequency allocation descriptor F and a predetermined frequency sequencing rule.

Abstract: For allocating time and frequency resources for at least one data transmission via a fast fading frequency selective channel between an access point of a wireless telecommunications network and at least one communication device located in at least one respective moving conveyance, a processing device: obtains long-term SINR information for a set of time and frequency resources; obtains at least one frequency correlation profile; obtains at least one time correlation profile; computes figures of merit for potential sequences of time and frequency resources, based on the obtained long-term signal-plus-interference to noise ratio information and on the obtained time and frequency correlation profiles; selects a sequence that provides a figure of merit that expects reaching a target quality of service for said data transmission(s) or that is the best figure or merit; allowing said data transmission(s) via the selected sequence.

Abstract: In order to perform synchronization and compensate clock drift among a plurality of communication devices interconnected to form a mesh communications network, all communication devices, except one given communication device, perform a first distributed consensus-based synchronization. The given communication device performs: obtaining a first correction information derived at least from a difference between a clock timing resulting from the first distributed consensus-based synchronization and a reference clock timing; and transmitting the first correction information through the mesh communications network. All the communication devices, except said given communication device, further perform updating the clock timing resulting from the first distributed consensus-based synchronization by taking into account the transmitted first correction information.
