Reliability enhancement in distributed system

A method of wireless communication of a base station, comprising:

• receiving first radio frequency (RF) signals on first RF time-frequency resources, the first RF signals carrying user data from a user equipment (UE);
• receiving second RF signals on second RF time-frequency resources, the second RF signals carrying the user data from the UE and being received from a wireless device that amplified initial RF signals transmitted by the UE on initial RF time-frequency resources to generate amplified RF signals and translated the amplified RF signals from the initial RF time-frequency resources to the second RF time-frequency resources to generate the second RF signals;
• obtaining first baseband signals from the first RF signals;
• obtaining second baseband signals from the second RF signals;
• and
• decoding the first baseband signals and the second baseband signals jointly to obtain the user data from the UE,
• wherein the first RF time-frequency resources and the second RF time-frequency resources do not overlap.

A wireless system comprising:

• a wireless device and a user equipment (UE),
• wherein the UE includes:
• a first memory;
• and
• at least one first processor coupled to the first memory and configured to:
• transmit, on first radio frequency (RF) time-frequency resources, first RF signals carrying user data to be sent to a base station;
• wherein the wireless device includes:
• a second memory;
• and
• at least one second processor coupled to the second memory and configured to:
• receive the first RF signals on the first RF time-frequency resources;
• amplify the first RF signals to generate amplified RF signals;
• translate the amplified RF signals from the first RF time-frequency resources to second RF time-frequency resources to generate second RF signals;
• and
• transmit, to the base station, the second RF signals on the second RF time-frequency resources, the second RF signals carrying the user data,
• wherein the first RF time-frequency resources and the second RF time-frequency resources do not overlap, and
• wherein the first RF signals and the second RF signals are configured such that first baseband signals derived from the first RF signals and second baseband signals derived from the second RF signals are jointly decoded by the base station to obtain the user data from the UE.
