Contention-free handoff return in a wireless network

摘要

A first enhanced Node B (eNB) and method for contention-free handoff return in a wireless network are provided. The first eNB in one example embodiment includes a transceiver system configured to communicate with a User Equipment (UE) and a processing system coupled to the transceiver system and configured to receive signal strength information from the UE, with the processing system being further configured to obtain a pre-handoff CF preamble for handoff of the UE from the first eNB to the second eNB, provide the pre-handoff CF preamble to the UE, generate a post-handoff CF preamble for the UE where the UE can use the post-handoff CF preamble to return from the second eNB to the first eNB, and provide the post-handoff CF preamble to the UE.

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.
