Wireless communication precoder determination

1. A method comprising:

acquiring first channel information associated with a first channel between a first node of a wireless communication network and a second node of the wireless communication network, the first node being configured to transmit a first wireless signal in a wireless communication resource to the second node via the first channel;

acquiring second channel information associated with a second channel between the first node and a third node of the wireless communication network, the third node being configured to receive a second wireless signal transmitted in the wireless communication resource; and

determining a precoder for transmission of the first wireless signal based on the first channel information and the second channel information, wherein determining the precoder includes determining a signal-to-leakage-and-noise ratio (SLNR) of the first wireless signal with respect to the second wireless signal based on the first channel information and the second channel information such that interference of the second wireless signal as caused by the first wireless signal is reduced.

2. The method of claim 1 , wherein:

the first node is a transmitting wireless device of a device-to-device (D2D) pair of wireless devices;

the second node is a receiving wireless device of the D2D pair; and

the third node is an access point of the wireless communication network.

3. The method of claim 1 , wherein:

the first node is a wireless device;

the second node is an access point of the wireless communication network; and

the third node is a receiving wireless device of a device-to-device (D2D) pair of wireless devices.

4. The method of claim 1 , wherein the first channel information is based on a reference signal transmitted by the second node and received at the first node.

5. The method of claim 1 , wherein the first channel information is based on a reference signal transmitted by the first node and received at the second node.

6. The method of claim 1 , wherein the second channel information is based on a reference signal transmitted by the third node and received at the first node.

7. The method of claim 1 , wherein the second channel information is based on a reference signal transmitted by the first node and received at the third node.

8. The method of claim 1 , wherein:

acquiring the first channel information includes locally determining the first channel information or receiving the first channel information; and

acquiring the second channel information includes locally determining the second channel information or receiving the second channel information.

9. The method of claim 1 , further comprising determining interference of the second wireless signal as caused by the first wireless signal based on the precoder.

10. A non-transitory computer-readable medium having encoded therein computer-executable instructions to perform operations, the operations comprising:

acquiring first channel information associated with a first channel between a first node of a wireless communication network and a second node of the wireless communication network, the first node being configured to transmit a first wireless signal in a wireless communication resource to the second node via the first channel;

acquiring second channel information associated with a second channel between the first node and a third node of the wireless communication network, the third node being configured to receive a second wireless signal transmitted in the wireless communication resource; and

determining a precoder for transmission of the first wireless signal based on the first channel information and the second channel information, wherein determining the precoder includes determining a signal-to-leakage-and-noise ratio (SLNR) of the first wireless signal with respect to the second wireless signal based on the first channel information and the second channel information such that interference of the second wireless signal as caused by the first wireless signal is reduced.

11. The non-transitory computer-readable medium of claim 10 , wherein:

the first node is a transmitting wireless device of a device-to-device (D2D) pair of wireless devices;

the second node is a receiving wireless device of the D2D pair; and

the third node is an access point of the wireless communication network.

12. The non-transitory computer-readable medium of claim 10 , wherein:

the first node is a wireless device;

the second node is an access point of the wireless communication network; and

the third node is a receiving wireless device of a device-to-device (D2D) pair of wireless devices.

13. The non-transitory computer-readable medium of claim 10 , wherein the first channel information is based on a reference signal transmitted by the second node and received at the first node.

14. The non-transitory computer-readable medium of claim 10 , wherein the first channel information is based on a reference signal transmitted by the first node and received at the second node.

15. The non-transitory computer-readable medium of claim 10 , wherein the second channel information is based on a reference signal transmitted by the third node and received at the first node.

16. The non-transitory computer-readable medium of claim 10 , wherein the second channel information is based on a reference signal transmitted by the first node and received at the third node.

17. The non-transitory computer-readable medium of claim 10 , wherein:

acquiring the first channel information includes locally determining the first channel information or receiving the first channel information; and

acquiring the second channel information includes locally determining the second channel information or receiving the second channel information.

18. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise determining interference of the second wireless signal as caused by the first wireless signal based on the precoder.
