Abstract
A method for providing wireless transmission diversity wherein an error correcting codeword is divided into first and second segments at first and second transmitting units. The first segments are transmitted from each of the first and second transmitting units and received at the first and second transmitting units, respectively. The received first segments are decoded and, responsive to the decoding, transmission of a second segment is made from each of the first and second transmitting units.
Claims18
A method for wireless transmission diversity, comprising the steps of:
- dividing an error correcting codeword into a first segment and a second segment at each of a first transmitting unit and a second transmitting unit;
- transmitting the first segments from each of the first transmitting unit and the second transmitting unit;
- receiving the transmitted first segments at each of the first transmitting unit and the second transmitting unit;
- decoding the received first segments at each of the first transmitting unit and the second transmitting unit;
- and
- responsive to the decoding, transmitting the second segments from each of the first transmitting unit and the second transmitting unit.
A method for wireless transmission diversity, comprising the steps of:
- dividing source data into blocks at each of a first transmitting unit and a second transmitting unit;
- adding bits to blocks for a CRC code at each of the first transmitting unit and the second transmitting unit;
- encoding the blocks using an error correcting code to create an error correcting codeword at each of the first transmitting unit and the second transmitting unit;
- dividing the error correcting codeword into a first segment and a second segment at each of a first transmitting unit and a second transmitting unit;
- transmitting the first segments from each of the first transmitting unit and the second transmitting unit;
- receiving the transmitted first segments at each of the first transmitting unit and the second transmitting unit;
- decoding the received first segments using a CRC code at each of the first transmitting unit and the second transmitting unit;
- and
- responsive to the decoding, transmitting the second segments from each of the first transmitting unit and the second transmitting unit.
A wireless communications system, comprising:
- a first mobile station for dividing an error correcting codeword into a first segment and a second segment and transmitting the first segment;
- a second mobile station for receiving the transmitted first segment, decoding the received first segments, and responsive to the decoding, transmitting a third segment;
- and
- a base station for receiving signals from the first and second mobile stations.
A mobile station in a wireless communications system, comprising:
- a receiver for receiving signals;
- a transmitter for transmitting signals;
- wherein said mobile station is configured to:
- divide an error correcting codeword into a first segment and a second segment;
- transmit the first segment using the transmitter;
- receive a transmitted first segment from other mobile stations using the receiver;
- decode the received first segment;
- and
- responsive to the decoding, transmitting a third segment using the transmitter.
