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 for use by a first base station, the method comprising:
(A) one or more communication interfaces; (B) one or more processors; and (C) memory storing instructions that, when executed by said one or more processors, cause said first base station to:
(i) transmit to a second base station and after making a handover decision for a wireless device, at least one first message comprising:
(1) one or more parameters indicating said 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(2) first configuration parameters of:
(a) j CSI reference signals for said carrier, j being an integer smaller than or equal to k; and(b) m CSI interference measurement resources for said carrier, m being an integer smaller than or equal to k;(ii) receive from said second base station, at least one second message comprising second configuration parameters of:
(1) p CSI reference signals, p being an integer smaller than or equal to k; and(2) q CSI interference measurement resources, q being an integer smaller than or equal to k; and(iii) transmit, to said wireless device and after receiving said at least one second message, a third message comprising said second configuration parameters of:
(1) said p CSI reference signals; and(2) said q CSI interference measurement resources.
