Abstract
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for link adaptation within coordinated multipoint systems. In various embodiments, a mobile terminal may determine link adaptation feedback information and feed back the information to a base station. The base station may adjust a channel quality indicator of the link adaptation feedback information based on loading of nodes within a coordinated multipoint measurement set. Other embodiments may be described and/or claimed.

30. An apparatus comprising:
-
a channel interference module to; receive, from a user equipment (UE), reference signal receive power (RSRP) information associated with a cooperating node of a coordinated multipoint (CoMP) measurement set, the cooperating node to coordinate with a serving node of the CoMP measurement set to facilitate wireless communication with the UE; receive, from the UE, a channel quality indicator (CQI); and determine an adjusted CQI based on the RSRP information and the CQI; and a link adaptation module to adapt transmission parameters of a communication link associated with the cooperating node or the serving node based on the adjusted CQI. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. An apparatus comprising:
-
a channel measurement module to; receive a channel state information reference signal (CSI-RS) transmitted by a cooperating node of a coordinated multipoint (CoMP) measurement set; and determine a reference signal receive power (RSRP) measurement for the cooperating node based on the CSI-RS; and a feedback module to feed back the RSRP measurement to a serving node of the CoMP measurement set as part of a radio resource management (RRM) measurement report. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51)

52. One or more computer readable media having instructions that, when executed, cause a device to:
-
determine cooperating node interference power associated with one or more cooperating nodes of a coordinated multipoint (CoMP) measurement set; determine total interference power on a physical downlink shared channel (PDSCH); determine a correction coefficient based on the cooperating node interference power and the total interference power; and determine one or more adjusted channel quality indicators (CQIs) based on the correction coefficient and one or more reported CQIs. - View Dependent Claims (53, 54, 55, 56)
