Method for transmitting TDD frames with increased data payload
View Patent ↗Method for transmitting through a bidirectional communication channel at least one conventional frame (CVFR) split into time slots SLI (for j=1 to L) separated from each other by guard intervals G, each time slot SLI being allocated either to a first or to a second direction of communication uplink (UL) or downlink (DL) offered by the bidirectional communication channel. The method according to the invention includes: detecting at least two successive time slots SLj, SLm+1, SLj+2 allocated to a same direction of communication DL, and inserting data in the guard interval separating such successive time slots SLj, SLj+1, SLj+2.
1. A method for generating a frame of constant total duration for transmitting information in a bi-directional communication channel, said frame being split into a predefined number of time slots, each time slot being allocated either to a first or a second direction of communication offered by said bi-directional communication channel, the method comprising:
arranging, at a transceiver, a guard interval only between two consecutive timeslots of said frame when said two time slots are allocated to opposite directions of communication;
adjusting the duration of said guard interval to a total duration for transmitting a multiple number of symbols; and
arranging pilot symbols at any position in the time slots.
2. A telecommunication system, comprising:
a base station; and
a mobile terminal configured to transfer in a first direction data to the base station into at least one time slot of a frame of constant total duration,
the base station configured to transfer in a second direction data to the mobile terminal into at another time slot of the frame, said frame being split into a predefined number of time slots,
the base station configured to arrange a guard interval only between two consecutive timeslots of said frame when said two time slots are allocated to opposite directions of communication, and to adjust the duration of said guard interval to a total duration for transmitting a multiple number of symbols and to arrange pilot symbols at any position in the time slots.
