Abstract
A method of transmitting a wireless signal (FIGS. 2 and 3A) is disclosed. A data stream (DATA) is received at a first transmitter (210). The data stream is also received by a second transmitter (214) that is remote from the first transmitter. The first transmitter (210) transmits a first part (S1) of the data stream to a remote receiver (220). The second transmitter (214) transmits a second part (S2) of the data stream to the remote receiver (220). The second transmitter (214) is remote from the first transmitter (210).
Claims50
A method of transmitting a wireless signal, comprising the steps of:
- receiving a first data stream at a first transmitter;
- receiving the first data stream at a second transmitter remote from the first transmitter;
- transmitting a first part of the data stream from the first transmitter to a remote receiver;
- and
- transmitting a second part of the data stream from the second transmitter to the remote receiver and not transmitting the first part of the data stream from the second transmitter to the remote receiver.
A method of receiving a wireless signal, comprising the steps of:
- receiving a first part of a data stream from a first transmitter;
- receiving a second part of the data stream and not the first part of the data stream from a second transmitter, the second transmitter being remote from the first transmitter;
- and
- combining the first part and the second part to produce the data stream.
A method of transmitting a wireless signal, comprising the steps of:
- receiving a first data stream at a first transmitter;
- receiving the first data stream at a second transmitter remote from the first transmitter;
- transmitting a first part of the data stream from the first transmitter to a remote receiver;
- and
- transmitting a second part of the data stream from the second transmitter to the remote receiver, wherein at least one of the steps of transmitting a first part and transmitting a second part includes transmitting with multiple antennas.
A method of receiving a wireless signal, comprising the steps of:
- receiving a first part of a data stream from a first transmitter;
- receiving a second part of the data stream, the second transmitter being remote from the first transmitter;
- and
- combining the first part and the second part to produce the data stream, wherein at least one of the steps of receiving a first part and receiving a second part includes receiving from multiple antennas of one of the first and second transmitters.
