Abstract: A wireless communication system supports communication between an end node of a vehicle and a correspondent node via a fixed network and wireless modems located with the vehicle. The fixed network comprises a mobility anchor being a common mobility anchor for the wireless modems and performing individual mobility management for each wireless modem, the mobility management for a wireless modem including determining communication paths from the mobility anchor to the wireless modem. A multipath proxy couples a proxy connection for the correspondent node to a plurality of subflows, each subflow being associated with one wireless modem and with the communication path determined by the mobility anchor, at least two of the subflows having communication paths via different wireless modems. The wireless modems are arranged to connect the end node and the plurality of subflows.

Abstract: A communication system supports communication between an end node (101) of a vehicle (103) and a remote correspondent node (105) via a fixed network (107) which comprises a plurality of wireless access points (109) with a directional antenna arrangement for mm wave radio communication using directional beams. A vehicle (103) comprises wireless modems (111, 113, 701, 703) employing electronically steerable beamforming directional antennas for establishing mm wave radio communication links to the access points (109). At least one first access point (109) is arranged to transmit multipath environment data for an area supported by the access point to the wireless modems (111, 113, 701, 703). A controller (1101) of the vehicle is arranged to set a diversity property for transmissions of data from the wireless modems to the wireless access points in response to the multipath environment data.

Abstract: A communication system comprises an access point communicating via a directional beam and a first and second wireless modem for establishing a first and respectively second mm wave radio communication link to the first access point. The first and second wireless modems are located on a vehicle and employ electronically steerable beamforming directional antennas having a first main beams for establishing the radio communication links A proximity detector detects proximity of the first wireless modem to the first access point. A switch controller switches data of a data flow from the first mm wave radio communication link to the second mm wave radio communication link in response to the detection of the proximity of the first wireless modem to the first access point.

Abstract: A communication system comprises access points (203, 205) communicating via directional beams and a first and second wireless modem (111, 701) for establishing a first and respectively second mm wave radio communication links to access points (203, 205). The first and second wireless modems (111, 701) are located on a vehicle (103) and employ electronically steerable beamforming directional antennas having a first main beams for establishing the radio communication links. A common network element (705) supports communication over both links and a connection control circuit (1001) switches between the links while providing a single wired connection point. A multipath controller (713) communicates with a complementary multipath controller of the fixed network over a plurality of paths with the multipath controller (713) having a first wired port for a first path of the plurality of paths connected to the first single wired connection point.

Abstract: An apparatus schedules communications in a wireless communication system comprising a plurality of wireless stations (103-107) operable to communicate wirelessly with each other in accordance with a time division multiple access scheme. The apparatus comprises a receiver (303) for receiving resource requests from the plurality of wireless stations (103-107). A scheduler (305) schedules air interface resource to communications between the plurality wireless stations by allocating time intervals in repeating scheduling intervals. A transmitter (301) transmits scheduling messages providing indications of the scheduling to the plurality of wireless stations (103-107). An adapter (307) adapts a duration of at least one scheduling interval of the repeating scheduling intervals in response to the resource requests from the plurality of wireless stations (103-107).

Abstract: A communication system comprises a fixed network comprising access points for mm wave radio communication using directional beams. A wireless modem of a vehicle comprises a first search circuit searching for a beacon transmission in a first frequency channel. A first data receiver extracts data from a detected beacon signal including: an indication of a first access point transmitting the beacon signal; a first load value indicative of a loading of the first access point; and an indication of a second access point having overlapping coverage with the first access point. Another receiver extracts data from a second beacon signal transmitted by the second access point in a second frequency channel including a second load value indicative of a loading of the second access point. A controller selects a target access point dependent on the first and second load values, and initializes a link setup with the target access point.
