1. A method comprising:
- transmitting, by a wireless device and to a first base station, a first message comprising one or more parameters indicating that the wireless device supports configuration of a first quantity of channel state information (CSI) processes per carrier;
receiving, by the wireless device and from the first base station, at least one second message comprising first configuration parameters for a second quantity of CSI interference measurement resources for a first carrier, wherein the second quantity is less than or equal to the first quantity; and
receiving, by the wireless device and from the first base station, a handover command to handover to a second base station, wherein the handover command comprises second configuration parameters for a third quantity of CSI interference measurement resources for a second carrier and associated with the second base station, wherein the third quantity is less than or equal to the first quantity,wherein the second configuration parameters in the handover command are from the second base station and are based on the one or more parameters indicating that the wireless device supports configuration of the first quantity of CSI processes.

Abstract
A wireless device may support a plurality of channel state information (CSI) processes. The wireless device may send an indication of a number of supported CSI processes to a first base station. The first base station may send an indication of a number of CSI processes supported by the wireless to a second base station. This information may be used during handover of the wireless device.
