1. A first enhanced Node B (eNB) for contention-free handoff return in a wireless network, the first eNB comprising:
a transceiver system configured to communicate with a User Equipment (UE); and
a processing system coupled to the transceiver system and configured to receive a signal strength information from the UE
via the transceiver system;
the processing system configured to obtain a pre-handoff CF preamble for handoff of the UE from the first eNB to a second
eNB and provide the pre-handoff CF preamble to the UE;
the processing system configured to generate a post-handoff CF preamble for the UE and a predetermined preamble expiration
time period, wherein the first eNB is configured to expire the post-handoff CF preamble after the predetermined preamble expiration
time period; and
the transceiver system configured to transfer the post-handoff CF preamble for delivery to the UE.
