20100322157 | SOLUTION FOR INE/HO LB BOTTLE NECK - A system and method for reducing an initial network entry and/or handover (INE/HO) Link Budget (LB) Bottleneck in a communications network, for example, a Worldwide Interoperability for Microwave Access (WiMAX) network described in the IEEE 802.16 specification, is arranged such that a Base Station (BS) may allocate bandwidth with repetition across at least two frames on Initial Network Entry/Handover (INE/HO) by a Mobile Station.
