Abstract
A method in a network node comprises determining (404) whether a wireless communication device is not high-speed capable. If so, a determination (406) is made of the position of the wireless communication device with respect to adjacent antenna nodes. Scheduling (408) of non-critical communication is then controlled in such way that it only is carried out within a certain range from each respective antenna node.

1-26. (canceled)
A method performed by a network node, where the network node is connected to a plurality of antenna nodes that are located along a path where a wireless communication device is moving, the method comprising:
- controlling the antenna nodes to maintain respective reception radio lobes and respective transmission radio lobes substantially along the path, such that the wireless communication device during movement along the path can communicate with the network node via consecutive reception radio lobes and via consecutive transmission radio lobes, and where the respective reception radio lobes of consecutive antenna nodes along the path oppose each other and the respective transmission radio lobes of consecutive antenna nodes along the path oppose each other,
- determining whether or not the wireless communication device is configured to operate in a high speed movement scenario,
- responsive to determining that the wireless communication device is not configured to operate in a high speed movement scenario:
- determining a position of the wireless communication device in relation to a first one of the antenna nodes located behind the wireless communication device and a second one of the antenna nodes located ahead of the wireless communication device, and
- controlling, based on the position of the wireless communication device, scheduling of non-time critical communication at least to the wireless communication device.
A network node configured to be connected to a plurality of antenna nodes that are located along a path where a wireless communication device is moving, the network node comprising input/output circuitry, a processor and a memory, said memory containing instructions executable by said processor whereby said network node is operative to:
- control the antenna nodes to maintain respective reception radio lobes and respective transmission radio lobes substantially along the path such that the wireless communication device during movement along the path can communicate with the network node via consecutive reception radio lobes and via consecutive transmission radio lobes, where the respective reception radio lobes of consecutive antenna nodes along the path oppose each other and where the respective transmission radio lobes of consecutive antenna nodes along the path oppose each other,
- determine whether or not the wireless communication device is configured to operate in a high speed movement scenario,
- responsive to determining that that the wireless communication device is not configured to operate in a high speed movement scenario:
- determine a position of the wireless communication device in relation to a first one of the antenna nodes located behind the wireless communication device and a second one of the antenna nodes located ahead of the wireless communication device, and
- control, based on the position of the wireless communication device, scheduling of non-time critical communication at least to the wireless communication device.
A non-transitory computer-readable medium storing a computer program comprising program instructions that, when executed on at least one processor in a network node that is connected to a plurality of antenna nodes that are located along a path where a wireless communication device is moving, configured the network node to:
- control the antenna nodes to maintain respective reception radio lobes and respective transmission radio lobes substantially along the path, such that the wireless communication device during movement along the path can communicate with the network node via consecutive reception radio lobes and via consecutive transmission radio lobes, and where the respective reception radio lobes of consecutive antenna nodes along the path oppose each other and the respective transmission radio lobes of consecutive antenna nodes along the path oppose each other,
- determine whether or not the wireless communication device is configured to operate in a high speed movement scenario,
- responsive to determining that the wireless communication device is not configured to operate in a high speed movement scenario:
- determine a position of the wireless communication device in relation to a first one of the antenna nodes located behind the wireless communication device and a second one of the antenna nodes located ahead of the wireless communication device, and
- control, based on the position of the wireless communication device, scheduling of non-time critical communication at least to the wireless communication device.
