SIGNALING OF EFFICIENT RANDOM ACCESS BASED ON AN EXPRESSION OF THE ASSIGNMENT OF A FIRST RANDOM ACCESS RESOURCE TO USE IN RELATION TO A SUBTRAME OF THE ASCENDING LINK.

摘要

A method for the transmission of data on a radio channel at a base station (20) of an evolved UMTS Terrestrial Radio Access Network, E-UTRAN, which operates in a Time Division Duplex mode, in which a frame comprises subframes assigned and divided between uplink transmission and downlink transmission, the method comprising - assigning (S2) a first random access resource to a first frequency in a first uplink subframe of a radio frame, characterized because the allocation step further comprises assigning a plurality of random access resources to be used with a plurality of uplink subframes and in which the plurality of random access resources is assigned by first spreading the plurality of random access resources over the plurality of uplink subframes in the first time in which at least one random access resource of the plurality of recurs is allocated Random access to use, when not enough uplink subframes are available over time to allocate the entire plurality of random access resources to the uplink subframes, on a frequency other than at least one uplink subframe, and - transmitting (S4) the data in the radio channel comprising an expression that expresses the assignment of the first random access resource to be used in relation to at least one uplink subframe.
