Handover signaling in wireless networks
First Claim
1. A method comprising:
- receiving, by a first base station and from a wireless device via a first legacy carrier, one or more parameters indicating whether the wireless device supports a new carrier type;
determining to perform a handover of the wireless device;
transmitting, to a second base station and prior to handover of the wireless device, a handover request comprising an indication that the wireless device supports the new carrier type;
receiving, by the first base station and responsive to the handover request, at least one message comprising configuration information for communications between the wireless device and the second base station, the configuration information comprising;
one or more identifiers of one or more legacy carriers; and
one or more identifiers of one or more new carrier type carriers, wherein each of the one or more new carrier type carriers is associated with at least one of the one or more legacy carriers; and
transmitting, by the first base station and to the wireless device, the configuration information.

Abstract
According to some aspects, a first base station may communicate with a second base station (e.g. during a handover process) regarding support of new carrier types by a wireless device. The first base station may receive parameters from a wireless device via a legacy carrier indicating whether the wireless device supports a new carrier type, and information about these parameters may be transmitted to the second base station. The first base station may receive messages for configuring communications between the wireless device and the second base station, which may include identification of legacy carriers and associated new carrier type carriers. The configuration information may be transmitted to the wireless device and the second base station may communicate with the wireless device based on the configuration information.
