Beamforming handover messaging in a wireless network

摘要

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.

主权项

1. A method comprising:
transmitting, by a first base station to a second base station and in response to a handover decision for a wireless device, at least one first message comprising at least one of:
one or more parameters indicating that the wireless device supports configuration of a first quantity of channel state information (CSI) processes for a carrier, the first quantity being greater than one; orfirst configuration parameters of a second quantity of CSI reference signals and of a third quantity of CSI interference measurement resources, wherein the second quantity and the third quantity are each less than or equal to the first quantity; receiving, from the second base station, at least one second message comprising:
second configuration parameters of a fourth quantity of CSI reference signals and of a fifth quantity of CSI interference measurement resources, wherein the fourth quantity and the fifth quantity are each less than or equal to the first quantity; and transmitting, to the wireless device, a third message comprising the second configuration parameters.
