Abstract
A first base station transmits a message to a second base station after a handover decision for a wireless device supporting beamforming and multiple carrier configurations. The message includes a plurality of measurement configuration parameters for the wireless device. The first base station receives a response from the second base stations. The first base station transmits a handover command to the wireless device subsequent to receiving the response message.
Claims20
A method comprising:
- transmitting, by a first base station to a second base station and after making a handover decision for a wireless device, at least one first message comprising at least one of:
- one or more parameters indicating the wireless device supports configuration of a maximum of k channel state information (CSI) processes for a carrier, k being an integer greater than one;
- and
- first configuration parameters of:
- j CSI reference signals for the carrier, j being an integer smaller than or equal to k;
- and
- m CSI interference measurement resources for the carrier, m being an integer smaller than or equal to k;
- receiving from the second base station, at least one second message comprising second configuration parameters of:
- p CSI reference signals, p being an integer smaller than or equal to k;
- and
- q CSI interference measurement resources, q being an integer smaller than or equal to k;
- and
- transmitting, to the wireless device and after receiving the at least one second message, a third message comprising the second configuration parameters.

A first base station comprising:
- one or more communication interfaces;
- one or more processors;
- and
- memory storing instructions that, when executed, cause the first base station to:
- transmit to a second base station and after making a handover decision for a wireless device, at least one first message comprising:
- one or more parameters indicating the wireless device supports configuration of a maximum of k channel state information (CSI) processes for a carrier, k being an integer greater than one;
- and
- first configuration parameters of:
- j CSI reference signals for the carrier, j being an integer smaller than or equal to k;
- and
- m CSI interference measurement resources for the carrier, m being an integer smaller than or equal to k;
- receive from the second base station, at least one second message comprising second configuration parameters of:
- p CSI reference signals, p being an integer smaller than or equal to k;
- and
- q CSI interference measurement resources, q being an integer smaller than or equal to k;
- and
- transmitting, to the wireless device and after receiving the at least one second message, a third message comprising the second configuration parameters.
