Method and system for implementing transmitting diversity and receiving diversity

A system for implementing transmitting diversity, comprising a mobile terminal in communication with a destination mobile terminal which is in the same mobile terminal group with the mobile terminal and a base station, wherein

• the mobile terminal is capable of:
• receiving a symbol from the destination mobile terminal;
• processing the symbol received from the destination mobile terminal;
• and
• transmitting the symbol processed to the base station.

A system for implementing receiving diversity, comprising a mobile terminal in communication with a destination mobile which is in the same mobile terminal group with the mobile terminal and a base station, wherein

• the mobile terminal is capable of:
• receiving a symbol from the base station;
• finding the destination mobile terminal if the mobile terminal is not the destination of the symbol;
• and
• forwarding the symbol to the destination mobile terminal.

A system for implementing receiving diversity, comprising a destination mobile terminal in communication with a mobile terminal which is in the same mobile terminal group with the destination mobile terminal and a base station;

• the destination mobile terminal is capable of:
• receiving a symbol from the base station;
• receiving a forwarded symbol from the mobile terminal, wherein the forwarded symbol is originally from the base station;
• combining the forwarded symbol from the mobile terminal and the symbol from the base station, and obtaining an estimate value of an original transmitted symbol.

A system for implementing symbol transmission, comprising a base station in communication with a destination mobile terminal and a mobile terminal which is in the same mobile terminal group with the destination mobile terminal, wherein

• the base station is capable of:
• receiving an uplink symbol transmitted directly from the destination mobile terminal;
• receiving an forwarded uplink symbol from the mobile terminal, wherein the forwarded uplink symbol is originally from the destination mobile terminal;
• combining the uplink symbol received from the destination mobile terminal and the uplink symbol forwarded by the at least one other mobile terminal;
• and
• obtaining an estimate value of an original transmitted uplink symbol.

A method for implementing receiving diversity, comprising:

• receiving, by a mobile terminal, a symbol from a base station;
• finding a destination mobile terminal which is in the same mobile terminal group with the mobile terminal if the mobile terminal is not the destination of the symbol;
• and
• forwarding the symbol to the destination mobile terminal.
