Methods and apparatus for reuse of a wireless resource

A first node comprising:

• at least one processor configured to:
• receive a first signal from a second node;
• measure the received power of the first signal;
• estimate a first SINR at the second node for a transmission from a third node to the second node in the presence of a transmission from the first node to a fourth node using a resource also used for the transmission from the third node to the second node;
• and
• decide, based on the first estimated SINR, whether to communicate with the fourth node using said resource;
• and memory coupled to said at least one processor.

A first node comprising:

• means for receiving a first signal from a second node;
• means for measuring the received power of the first signal;
• means for estimating a first SINR at the second node for a transmission from a third node to the second node in the presence of a transmission from the first node to a fourth node using a resource also used for the transmission from the third node to the second node;
• and
• means for deciding, based on the first estimated SINR, whether to communicate with the fourth node using said resource.

A computer program product for use in a first node, the computer program product comprising:

• a computer readable medium comprising:
• code for causing at least one computer to receive a first signal from a second node;
• code for causing said at least one computer to measure the received power of the first signal;
• code for causing said at least one computer to estimate a first SINR at the second node for a transmission from a third node to the second node in the presence of a transmission from the first node to a fourth node using a resource also used for the transmission from the third node to the second node;
• and
• code for causing said at least one computer to decide, based on the first estimated SINR, whether to communicate with the fourth node using said resource.
