Method and node for listening

A first node, comprising:

• a processor, configured to:
• obtain first time-frequency position information corresponding to the first node based on a first listening pattern corresponding to the first node, wherein the first time-frequency position information corresponding to the first node specifies multiple radio frames in which the first node is to send listening reference signals corresponding to the first node and one radio frame in which the first node is to receive at least one listening reference signal corresponding to at least one other node;
• and
• a communications interface, configured to:
• send, in a listening pilot time slot of a first radio frame in accordance with the first time-frequency position information, a first listening reference signal to a second node, wherein the first listening reference signal enables the second node to obtain interference information corresponding to the first node and/or a resource configuration of the first node;
• and
• receive, in a listening pilot time slot of a second radio frame in accordance with the first time-frequency position information, a second listening reference signal from the second node, wherein the second listening reference signal enables the first node to obtain interference information corresponding to the second node and/or a resource configuration of the second node.

A non-transitory computer-readable medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed by a processor, facilitate:

• obtaining, by a first node, first time-frequency position information corresponding to the first node based on a first listening pattern corresponding to the first node, wherein the first time-frequency position information corresponding to the first node specifies multiple radio frames in which the first node is to send listening reference signals corresponding to the first node and one radio frame in which the first node is to receive at least one listening reference signal corresponding to at least one other node;
• sending, by the first node, in a listening pilot time slot of a first radio frame in accordance with the first time-frequency position information, a first listening reference signal to a second node, wherein the first listening reference signal enables the second node to obtain interference information corresponding to the first node and/or a resource configuration of the first node;
• and
• receiving, by the first node, in a listening pilot time slot of a second radio frame in accordance with the first time-frequency position information, a second listening reference signal from the second node, wherein the second listening reference signal enables the first node to obtain interference information corresponding to the second node and/or a resource configuration of the second node.
