Abstract
This disclosure describes systems, methods, and devices related to a distributed relay. The distributed relay may utilize beamforming and/or a specific physical arrangement of transmit and receive antennas to ensure a high isolation between antennas. The distributed relay may further facilitate the concurrent operation of two different intermediate frequency (IF) chains to support communications between a network entity and user device, receiving and transmitting data on each of the two IF chains independently of one another.

1-22. (canceled)
A device, comprising:
- a donor side including a donor receive antenna and a donor transmit antenna, the donor receive antenna being coupled to first receive intermediate frequency (IF) circuitry included in a first IF chain, and the donor transmit antenna being coupled to first transmit IF circuitry included in a second IF chain,
- an access side including an access transmit antenna and an access receive antenna, the access transmit antenna being coupled to second transmit IF circuitry included in the first IF chain, and the access receive antenna being coupled to second receive IF circuitry included in the second IF chain,
- wherein the first IF chain is configured to enable the access transmit antenna to transmit signals based on signals received via the donor receive antenna,
- wherein the second IF chain is configured to enable the donor transmit antenna to transmit signals based on signals received via the access receive antenna,
- wherein the first receive IF circuitry and the first transmit IF circuitry are physically separated from one another, and the second receive IF circuitry and the second transmit IF circuitry are physically separated from one another, and
- wherein the first IF chain and the second IF chain are configured to receive signals and transmit signals independently of one another.
A method implemented via one or more processors of a relay comprising a donor side including a donor receive antenna and a donor transmit antenna, and comprising an access side including an access transmit antenna and an access receive antenna, the method comprising:
- transmitting, via the donor transmit antenna using a first IF chain that is coupled to the access receive antenna and to the donor transmit antenna, signals based on signals received via the access receive antenna;
- and
- transmitting, via the access transmit antenna using a second IF chain that is coupled to the donor receive antenna and to the access transmit antenna, signals based on signals received via the donor receive antenna,
- wherein the acts of transmitting and receiving signals via the first IF chain and the second IF chain occur independently of one another.
A non-transitory computer-readable media of a relay having instructions stored thereon, the relay comprising a donor side including a donor receive antenna and a donor transmit antenna, and comprising an access side including an access transmit antenna and an access receive antenna, the instructions being executed by one or more processors of the relay to cause the relay to:
- transmit, via the donor transmit antenna using a first IF chain that is coupled to the access receive antenna and to the donor transmit antenna, signals based on signals received via the access receive antenna;
- and
- transmit, via the access transmit antenna using a second IF chain that is coupled to the donor receive antenna and to the access transmit antenna, signals based on signals received via the donor receive antenna,
- wherein transmitting and receiving signals occurs independently via each of the first IF chain and the second IF chain.
