Abstract
A system and method for improved data transmission in a WDCT frame structure. A transmission slot in a WDCT frame of conventional size is configured for transmission of data bits having substantially smaller data bit width than used in conventional WDCT frames. A user data field is configured to transmit a larger data payload by including more bits within the user data field. In one implementation, the user data field is configured for transmission of multiple copies of a voice data packet at the same rate as single data packets are transmitted in a conventional WDCT frame structure. In another implementation, a non-voice data transmission rate is increased by more than a factor of two over conventional WDCT frame structure.
Claims22
A system for increasing a payload in a time division multiple access frame, comprising:
- a transmitting device configured to transmit digital data bits having a reduced data bit width having a duration that is smaller by an integer factor N than a conventional WDCT bit width of a TDMA technology, wherein the transmitting device is configured to transmit the digital data bits in a frame structure of an RF duplex link, the frame structure comprising:
- an enhanced user data field having larger bit size by the integer factor N than a user data field size of a conventional frame of the TDMA technology, wherein the enhanced user data field comprises the integer factor N number of data fields compared to conventional TDMA technology, wherein each data field comprises data packets, wherein a first data packet and a copy of the first data packet are sent in consecutive frames, and wherein the enhanced user data field is configured to send N different data packets within a single frame;
- and
- a frame duration the same as a conventional WDCT frame of the TDMA technology, wherein a data payload transmitted over a duplex link having a first slot of a first slot size is larger by the integer factor N than a data payload of a conventional WDCT frame structure of the TDMA technology having the first slot size.
A method for improved data transmission in a TDMA system, comprising:
- establishing a data bit width smaller than a conventional WDCT data bit width of a TDMA technology by a factor of N, where N is an integer greater than one;
- arranging a frame structure of the TDMA technology to provide N user data fields within a designated transmission slot, each user field comprising a data packet;
- buffering each data packet in a transmitting device buffer;
- transmitting N copies of each data packet in consecutive frames of the TDMA frame structure, such that each frame of the TDMA frame structure comprises a sequence of N different data packets in the N user fields;
- storing the copies of the data packets in a receiving buffer of a receiving device until the N copies are received;
- assembling a best copy from the N copies of the data packet stored in the receiving buffer by selecting good sub-packets from portions of the N copies of the data packet and building a new copy of the N copies of the data packet using the good sub-packets;
- and
- transmitting the best copy of the first data packet from the receiving buffer for playback in the receiving device.
