Method for signalling time and frequency resources allocation in wireless communication system

An access point adapted for performing K individual transmissions between said access point intended to manage a cell of a wireless communications network and plural mobile terminals intended to be attached to said access point within said cell, the K individual transmissions being intended to be performed via time and frequency resources from amongst a predefined set of candidate time and frequency resources on a per frame period basis, each time and frequency resource being a predefined frequency resource usable over a predefined time resource, one time and frequency resource being intended to be allocated to each one of the K individual transmissions in a considered frame period, characterized in that the access point comprises:

• means for obtaining a first frequency allocation descriptor F indicating which frequency resource is allocated in the considered frame period to each one of the K individual transmissions;
• means for obtaining 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;
• means for signalling the frequency occurrence descriptor G in said cell;
• and
• means for enabling transmission of data for the K individual transmissions in accordance with the first frequency allocation descriptor F and a predetermined frequency sequencing rule, the predetermined frequency sequencing rule indicating in which order the candidate frequency resources shall be considered in view of the frequency occurrence descriptor G within the frame periods,
• and wherein the access point further comprises means for providing an indication enabling the mobile terminals attached thereto to determine which time resource in the considered frame period is associated with each one of the K individual transmissions.

A mobile terminal adapted for receiving data of one among K individual transmissions from an access point managing a cell of a wireless communications network to plural mobile terminals intended to be attached to said access point within said cell, the K individual transmissions being intended to be performed via time and frequency resources from amongst a predefined set of candidate time and frequency resources on a per frame period basis, each time and frequency resource being a predefined frequency resource usable over a predefined time resource, one time and frequency resource being intended to be allocated to each one of the K individual transmissions in a considered frame period, characterized in that said mobile terminal, which is intended to be attached to the access point, comprises:

• means for receiving via signalling 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;
• means for determining, from the received frequency occurrence descriptor G and from a predetermined frequency sequencing rule, a second frequency allocation descriptor F′ describing which frequency resource has been allocated for each time resource in sequence of the considered frame period, the predetermined frequency sequencing rule indicating in which order the candidate frequency resources shall be considered in view of the frequency occurrence descriptor G within the frame periods;
• means for obtaining from the access point an indication enabling the mobile terminals attached to said access point to determine which time resource in the considered frame period is associated with each one of the K individual transmissions;
• and
• means for receiving data for the K individual transmissions in accordance with the second frequency allocation descriptor F′ and further in accordance with the obtained indication.
