Patent ID: 8908616

Claim:
A method of transmitting data signals from a first device to a second device during a cycle of a synchronous wireless communication channel implementing a time division multiplexing scheme, wherein the cycle comprises: a first and a second configuration time slots allotted respectively to the first and to the second devices for emitting reference signals and M (M>1) communication time slots, each of them allotted to the first device to emit data signals to the second device following one transmission path, associated with said communication time slot, among a set of K transmission paths between the first and the second devices, the method being performed by first device during said cycle and comprising the steps of: emitting a reference signal following, at least, the K transmission paths during the first configuration time slot; identifying valid transmission paths among the set of K transmission paths by listening, according to each transmission path of the set, for a feedback reference signal from the second device during the second configuration time slot; and emitting data signals in each communication time slot of which the associated transmission path has been identified as valid, wherein the second configuration time slot contains M sub-slots uniquely associated with the M communication slots, and wherein the step of identifying valid transmission paths comprising: during each sub-slot, listening for the feedback reference signal according to, successively, all the K transmission paths; and for each sub-slot during which the feedback reference signal has been detected, identifying the transmission path according to which the reference signal has been detected as valid and associating said transmission path to the communication time slot associated with said sub-slot.
