Abstract
To minimize a number of uplink/downlink conflicts when at least some of the subframes within a transmission frame may be flexible allocated either to uplink or to downlink, a network node, which is configured to provide wireless access to user devices in a cell, is configured to determine in the cell and its neighboring cells uplink/downlink ratios of at least the flexible subframes, and based on the uplink/downlink ratios, determine, from a look-up-table, optimal link direction assignments at least for the flexible subframes, and to cause transmissions using the optimal link direction assignments.

1-19. (canceled)
A network node configured to provide wireless access via a cell, the network node comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and computer program code configured to, with the at least one processor, cause the network node at least to perform:
- determining in the cell and in its neighboring cells uplink/downlink ratios of at least flexible subframes within a transmission frame, a flexible subframe being a subframe that is flexibly assignable for uplink or for downlink;
- determining, based on the uplink/downlink ratios, using a look-up-table comprising mappings between at least some uplink/downlink ratios and their optimal link direction assignments, optimal link direction assignments at least for the flexible subframes in the cell and its neighboring cells;
- and
- causing using the optimal link direction assignments in one or more transmissions.
A method for a network node configured to provide wireless access via a cell, the method comprising:
- determining in the cell and in its neighboring cells uplink/downlink ratios of at least flexible subframes within a transmission frame, a flexible subframe being a subframe that is flexibly assignable for uplink or for downlink;
- determining, based on the uplink/downlink ratios, using a look-up-table comprising mappings between at least some uplink/downlink ratios and their optimal link direction assignments, optimal link direction assignments at least for the flexible subframes in the cell and its neighboring cells;
- and
- causing using the optimal link direction assignments in one or more transmissions.
A non-transitory computer readable medium comprising program instructions for causing a network node configured to provide wireless access via a cell to perform at least the following:
- determining in the cell and in its neighboring cells uplink/downlink ratios of at least flexible subframes within a transmission frame, a flexible subframe being a subframe that is flexibly assignable for uplink or for downlink;
- determining, based on the uplink/downlink ratios, using a look-up-table comprising mappings between at least some uplink/downlink ratios and their optimal link direction assignments, optimal link direction assignments at least for the flexible subframes in the cell and its neighboring cells;
- and
- causing using the optimal link direction assignments in one or more transmissions.
