A method for allocating transmission resources in a wireless communications network for performing K individual transmissions between an access point (110; 111) and plural mobile terminals (120, 121, 122; 123, 124), the transmissions occurring in the wireless communications network on a per frame basis, the method being performed by a managing device in charge of allocating the transmission resources for performing the K individual transmissions, signalling information intended to enable the mobile terminals to determine transmission resources that are allocated in a subsequent frame being transmitted in at least one transmission resource of each frame, wherein, for each one of the K individual transmissions, the managing device has information representative of a signal-plus-interference to noise ratio expected for each transmission resource when used by said individual transmissions, and the managing device has information representative of a signal-plus-interference to noise ratio expected for each transmission resource when said transmission resource is used for transmitting the signalling information, wherein the managing device performs, when considering allocating transmission resources for the K individual transmissions in a frame identified by an index value t: - obtaining information representative of the transmission resources allocated beforehand from the frame identified by the index value t-W T+2 to the frame identified by the index value t-1, wherein W ≥ 1 is a first predefined quantity of successive frames and T ≥ 1 is a second predefined quantity of successive frames; - allocating transmission resources in the frame identified by the index value t for performing the K individual transmissions and transmission resources in the frame identified by an index value t-x for transmitting the signalling information related to the frame identified by the index value t, by reviewing transmission resources allocations from the frame identified by the index value t-W+1 to the frame identified by the index value t-1 for maximizing the following expression: min 0 ≤ u < W P t − u wherein x ≥ 1 represents a difference in terms of quantity of frames between the frame identified by the index value t and the preceding frame in which is transmitted the signalling information related to the frame identified by the index value t, and wherein W ≥ x, and wherein P(t-u) is a figure of merit representative of a probability that at least one message in each one of the K individual transmissions is correctly received between the frame identified by the index value t-u-T+1 and the frame identified by the index value t-u in view of the signal-plus-interference to noise ratio; then - enabling transmission of the frame identified by the index value t-W-x+1. - obtaining information representative of the transmission resources allocated beforehand from the frame identified by the index value t-W T+2 to the frame identified by the index value t-1, wherein W ≥ 1 is a first predefined quantity of successive frames and T ≥ 1 is a second predefined quantity of successive frames; - allocating transmission resources in the frame identified by the index value t for performing the K individual transmissions and transmission resources in the frame identified by an index value t-x for transmitting the signalling information related to the frame identified by the index value t, by reviewing transmission resources allocations from the frame identified by the index value t-W+1 to the frame identified by the index value t-1 for maximizing the following expression: min 0 ≤ u < W P t − u - enabling transmission of the frame identified by the index value t-W-x+1.
