Abstract

A method performed by a base station may comprise: receiving RADAR information; sending scheduling information, wherein the scheduling information includes a set of time and frequency resources associated with a physical downlink transmission that avoid RADAR interference, and wherein the set of time and frequency resources is determined based on the RADAR information; and sending the physical downlink transmission using resources based on the set of time and frequency resources.

Claims (18)

1 . A method implemented by a base station, the method comprising:

receiving radio detection and ranging (RADAR) structured parameters including an angle of arrival (AOA), frequency information, and bandwidth (BW);

sending scheduling information for transmitting to a wireless transmit receive unit (WTRU), wherein the scheduling information is associated with a spatial direction and indicates a set of time and frequency resources associated with a physical downlink transmission that avoid RADAR interference, and wherein the set of time and frequency resources is determined based on the RADAR structured parameters and a location of the WTRU; and

sending the physical downlink transmission using resources based on the set of time and frequency resources.

2 . The method of claim 1 , wherein the set of time and frequency resources are further based on a RADAR interference threshold.

3 . The method of claim 1 , wherein the set of time and frequency resources are further based on a timing drift associated with RADAR.

4 . The method of claim 1 , wherein the physical downlink transmission includes a physical downlink shared channel transmission.

5 . The method of claim 1 , wherein the scheduling information is sent in a downlink control information.

6 . A base station comprising:

a transceiver;

a processor connected to the transceiver, wherein the processor and transceiver are configured to:

receive radio detection and ranging (RADAR) structured parameters including angle of arrival (AOA), frequency, and bandwidth (BW), usable by the base station for determining time and frequency resources for transmission scheduling;

send scheduling information for transmitting to a wireless transmit receive unit (WTRU), wherein the scheduling information is associated with a spatial direction and indicates a set of time and frequency resources associated with a physical downlink transmission that avoid RADAR interference, and wherein the set of time and frequency resources is determined based on the RADAR structured parameters and a location of the WTRU; and

send the physical downlink transmission using resources based on the set of time and frequency resources.

7 . The base station of claim 6 , wherein the set of time and frequency resources are further based on a RADAR interference threshold.

8 . The base station of claim 6 , wherein the set of time and frequency resources are further based on a timing drift associated with RADAR.

9 . The base station of claim 6 , wherein the physical downlink transmission includes a physical downlink shared channel transmission.

10 . The base station of claim 6 , wherein the scheduling information is sent in a downlink control information.
