Abstract
For uplink cooperation of a serving access node (100-1) one or more supporting access nodes (100-2) are selected. The selection is based on a characteristic of a link between a terminal (200) served by the serving access node (100-1) and the supporting access node (100-2), or is based on a characteristic of a link between a further terminal (200′) served by the supporting access node (100-2) and the serving access node (100-1). The characteristics of the links may comprise a signal quality, e.g. a path gain, a signal strength, or a latency. The characteristics of the links may also comprise scheduling information, e.g. time resources and/or frequency resources used on the link.

17. A method for cooperatively receiving an uplink signal from a first terminal served by a first access node, the method comprising:
-
determining at least one of; a first characteristic of a first link from the first terminal to a second access node that serves a second terminal; and a second characteristic of a second link from the second terminal to the first access node; determining a third characteristic of a third link between the first terminal and the first access node; and selecting the second access node to support cooperative reception of the uplink signal, based on a comparison of the third characteristic with at least one of the first characteristic and the second characteristic. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A first access node configured to serve a first terminal and to cooperatively receive an uplink signal from that first terminal, and the first access node comprising a processor configured to:
-
determine at least one of; a first characteristic of a first link from the first terminal to a second access node that serves a second terminal; and a second characteristic of a second link from the second terminal to the first access node; determine a third characteristic of a third link between the first terminal and the first access node; and select the second access node to support cooperative reception of the uplink signal, based on a comparison of the third characteristic with at least one of the first characteristic and the second characteristic. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A computer program product stored on a computer-readable medium and comprising code that, when executable by a processor of a first access node, cause the first access node to serve a first terminal and to cooperatively receive an uplink signal from that first terminal, the code causing the first access node to:
-
determine at least one of; a first characteristic of a first link from the first terminal to a second access node that serves a second terminal; and a second characteristic of a second link from the second terminal to the first access node; determine a third characteristic of a third link between the first terminal and the first access node; and select the second access node to support cooperative reception of the uplink signal, based on a comparison of the third characteristic with at least one of the first characteristic and the second characteristic.
