This paper proposes a wireless local area network over densely-laid small cells with 3G-LTE protocol, and discusses hand over procedures for it. This network contributes to integration of telephones and LAN. It serves not only its own users but also visitors. Considering use of millimeter waves, cell radius will be about 10m at largest, and this requests quick handover since handover happens frequently though UE (User Equipment) moves at walking speed. In MIMO (Multiple-Input Multiple-Output) cell, conventional handover procedures in which an old base station (BS) requests handover to a target BS cannot be applied, since radio power drops sharply at cell edge. So, the target UE directly triggers handover to a target BS with SR (Schedule Request) signal on PUCCH (Physical Uplink Control CHannel). To achieve this, all BSs are synchronously orated under a clock of PON (Passive Optical Network) for backhaul network. Furthermore, before handover, SR code should be notified to the target UE, and UE’s ID and downward packets should be stored in each target BS. If reservation should be skipped to save resources, packet pre-storage and reservation of SR signal demanding contention are required. |
