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 to the wireless device a handover command, instructing the wireless device to handover to a second base station. The handover command may comprise configuration parameters for CSI processes associated with the second base station. The configuration parameters may be based on the number of CSI processes supported by the wireless device.
Claims24
A method comprising:
- receiving, by a first node and from a wireless device, at least one first message indicating that the wireless device supports configuration of a first quantity of channel state information (CSI) reports for a plurality of resource blocks;
- transmitting, by the first node and to the wireless device, at least one second message comprising configuration parameters for a second quantity of CSI reference signals for the plurality of resource blocks, wherein the second quantity is less than or equal to the first quantity;
- and
- transmitting, by the first node to a second node and based on a determination to perform a handover for the wireless device, at least one third message indicating the configuration parameters for the second quantity of CSI reference signals.
1 more element
A first node comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the first node to:
- receive, from a wireless device, at least one first message indicating that the wireless device supports configuration of a first quantity of channel state information (CSI) reports for a plurality of resource blocks;
- transmit, to the wireless device, at least one second message comprising configuration parameters for a second quantity of CSI reference signals for the plurality of resource blocks, wherein the second quantity is less than or equal to the first quantity;
- and
- transmit, to a second node and based on a determination to perform a handover for the wireless device, at least one third message indicating the configuration parameters for the second quantity of CSI reference signals.

A method comprising:
- transmitting, by a first node to a second node and based on a handover decision for a wireless device, at least one first message indicating that the wireless device supports configuration of a first quantity of channel state information (CSI) reports for a plurality of resource blocks;
- receiving, by the first node and from the second node, at least one second message comprising second configuration parameters for a second quantity of CSI reference signals, wherein the second quantity is less than or equal to the first quantity;
- and
- transmitting, by the first node and to the wireless device, a third message comprising the second configuration parameters.
