Abstract
Infrastructure relays are used to relay signals to multi-antenna receivers where the received signals are then processed using MIMO processing. The transmissions can use spatial multiplexing and/or space time block coding.
Claims7
A method comprising:
- a first wireless node transmitting to a second wireless node;
- a third wireless node transmitting to the second wireless node;
- the second wireless node performing MIMO processing on signals received from the first wireless node and the third wireless node;
- wherein the third wireless node is a relay re-transmitting content received from a fourth wireless node, the fourth wireless node operating in a first mode of operation;
- the first wireless node is a mobile station;
- and
- the second wireless node is a base station.
