Abstract: Methods and apparatuses exemplified in this disclosure provide mechanisms for a wireless communication device to indicate its Radio Access Technology (RAT) preferences to a wireless communication network, and for a wireless communication network to consider the RAT preferences of a given device when deciding which RAT the device will use. As a non-limiting example of the advantages flowing from these mechanisms, devices operating within a network that includes or is associated with multiple RATs can indicate their preferences for which RAT they use, while still allowing the network to retain control of the RAT selection decisions. Such flexibility offers significant advantages in 5G networks that provide tight integration between multiple RATs—e.g., between LTE and NR air interfaces. However, the methods and apparatuses disclosed herein are not limited to 5G networks.

Abstract: Coordination information for controlling base-station-to-base-station interference is transmitted from one radio network node (900) (e.g., an LTE eNodeB) to another, using certain parts of the TDD subframe. One example method, as might be implemented in a radio network node (900) such as an LTE eNodeB, includes the generating (1010) of a TDD coordination signal and the transmitting (1020) of the TDD coordination signal to one or more other radio network nodes. In some embodiments, the coordination signal is transmitted in a guard period of a special subframe at the target node. In others, the coordination signal is transmitted in another interval during which the receiving node is not transmitting, such as in uplink subframe for the receiving node, an uplink portion of a special subframe at the receiving node, or in a downlink subframe or downlink portion of a special subframe during which the receiving node is not transmitting.

Abstract: A wireless communication system (14) comprises points that have time division duplex, TDD, configurations. Information is obtained indicating the TDD configuration of each of multiple points to which a particular wireless communication device (6) is simultaneously connected.

For the device (6), each of the one or more conflicting resources are resolved as either an uplink resource to be used by the device (6), a downlink resource to be used by the device (6), or a resource not to be used by the device (6), based on one or more rules for optimizing use of conflicting resources.
