摘要： The use of wireless backhaul poses special challenges for in-vehicle base stations. Users that are connected to an in-vehicle base station expect continuous service, even as the in-vehicle base station passes in and out of different wireless backhaul coverage zones, such as when a train passes from a train station with good coverage to a tunnel with poor coverage. The base station thus needs seamless backhaul handover. A system that enables an in-vehicle base station to receive continuous service across different backhaul coverage zones is needed. To solve this problem, a system enabling handover is described. The system involves double-tunneling mobile device data packets in an ESP-UDP IPsec tunnel encapsulated in a GTP-U tunnel. Traffic is transmitted from a mobile device to a specially configured base station that encapsulates mobile device data packets and sends them to the network via wireless backhaul using an LTE UE modem connection.

摘要： A system is disclosed, comprising: a solar panel; an electric power supply source; a wireless fronthaul access point coupled to a radio mast and in communication with a remote baseband unit, the wireless fronthaul access point further comprising a first millimeter wave wireless interface; a self-organizing network module in communication with a coordinating server; and an antenna-integrated radio for providing access to user equipments (UEs), mounted within line of sight on the radio mast with the wireless fronthaul access point, the antenna-integrated radio further comprising: a second millimeter wave wireless interface configured to receive the digital I and Q signaling information from the remote baseband unit wirelessly via the wireless fronthaul access point, wherein the wireless fronthaul access point thereby wirelessly couples the remote baseband unit and the antenna-integrated radio. Synchronization is used to pack used resource blocks to reduce the duty cycle of the PAs, thereby reducing power.

摘要： A radio resource scheduler at a first base station may be configured to: identify radio frequency resources in use by the first base station, identify radio frequency resources to be reserved as virtual guard bands to reduce adjacent band interference, and install virtual guard band rules for reducing interference with adjacent bands. The virtual guard band information may be hints, allocations, priorities, reservations, or scheduling instructions for avoiding certain radio resources, radio resource blocks, or frequencies.

摘要： Systems and methods for performing handover coordination between base stations are disclosed. In a first embodiment, a method is disclosed, comprising: receiving, at a base station, a first serving cell signal measurement and a first neighbor cell signal measurement from a particular user equipment (UE); sending an adjustment message, from the base station to the UE, containing a cell-specific offset of the serving cell and a cell-specific offset of the neighbor cell in a reporting threshold based on at least one handover adjustment factor received from a coordinating node; receiving, at the base station and subsequent to adjusting the cell-specific offsets, a second serving cell signal measurement and a second neighbor cell signal measurement; and deciding whether to trigger a handover event based on the first and the second serving cell signal measurement and the first and the second neighbor cell signal measurement and the cell-specific offsets.
