Abstract

A serving base station transmits to a target base station a first message comprising a parameter indicating whether a wireless device supports an enhanced physical downlink control channel (ePDCCH). The serving base station receives from the target base station a second message comprising parameters indicating: a configuration of a subset of subframes in which first radio resources of a first ePDCCH are configured; and a starting OFDM symbol of the first ePDCCH in the subset of subframes. The serving base station transmits a third message to the wireless device comprising the configuration information of the first ePDCCH.

First claim

What is claimed is:

1. A method comprising:
transmitting, by a first base station, to a second base station and in response to the first base station making a handover decision for a wireless device, a first message comprising a parameter indicating whether the wireless device supports an enhanced physical downlink control channel (ePDCCH);
receiving, from the second base station, a second message comprising configuration parameters of one or more carriers for the wireless devic…
