摘要

Methods of operating a wireless terminal may be provided. A high-speed indication may be received for a cell of a network node indicating that the cell is adapted to operate in a high-speed environment, and operation of the wireless terminal may be adapted to communicate through the cell of the network node in the high-speed environment responsive to receiving the high-speed indication. Methods of operating a node of a wireless communication network may also be provided. Communication service may be provided through a cell to a plurality of wireless terminals in a high-speed environment, and a high-speed indication may be transmitted through the cell to one of the plurality of wireless terminals, with the high-speed indication indicating that the cell is adapted to operate in a high-speed environment.

Non-limiting examples of deployment parameters associated with different HST networks, HST #1 and HST #2, are shown in FIGS. 6 and 7 respectively. These HST scenarios are reproduced from 3GPP TS 36.104. The corresponding parameters for these HST scenarios are expressed in the table of FIG. 8. The figures show that the HST scenarios 1 and 2 differ in terms of deployment parameters such as distance between base station sites, maximum speed of the train, minimum distance between a base station and the track of the train, and maximum Doppler speed.

In some scenarios, carrier aggregation or dual connectivity may be used to combine connectivity from the dedicated high speed vehicle network with connectivity from the so called public network, which should be understood as a network which has not been specifically provided for high speed vehicle users (i.e., a network which provides service to UEs operating also at lower speeds).
