Claim of US Patent No. 9,788,265

1. A method for managing the accessibility of an uplink channel, of a control channel and/or data channel type, for a communications
network infrastructure with a plurality of pieces of radio equipment, in which the accessibility to said uplink channel is
transmitted on a downlink channel of said network infrastructure to said pieces of radio equipment by means of status symbols
indicating if access to said uplink channel is authorised during a timeslot, the method comprising:
receiving during a first timeslot a message on the uplink channel coming from a piece of radio equipment, said message comprising
an indicator in order to indicate a length type of said message followed, when said message is of the long type, by a header
block,

reading of said indicator indicating the type of length and, when said message is of the long type:
modifying a status symbol of a second timeslot consecutive to the first timeslot to indicate a busy state;
determining the length of said message received using a processing of the header block;
determining a number Nb of total timeslots corresponding to said determined length;
and if the number Nb of total timeslots is greater than or equal to 3:
modifying a status symbol of the Nb?2 timeslots consecutive to the second timeslot to indicate a busy state.
