    Abstract: According to certain embodiments, a method by a wireless device is provided for resource sensing. The method includes acquiring, from a network node, an indication of resources associated with a first resource pool. The first resource pool is for use in an exceptional communication with another device. A triggering event associated with signalling from the network node is identified. Based on the triggering event, a need for the exceptional communication with the other device is determined. At least one resource is selected from the first resource pool, and a message is transmitted using the at least one resource selected from the first resource pool.

    Abstract: Systems and methods are disclosed for estimating one or more channel properties of a downlink from a cellular communications network based on quasi co-located antenna ports with respect to the one or more channel properties. In one embodiment, a wireless device (16) receives a downlink subframe including a downlink control channel from the cellular communications network (10). The wireless device (16) estimates one or more large-scale channel properties for an antenna port of interest in the downlink control channel based on a subset of reference signals that correspond to antenna ports in the cellular communications network (10) that are quasi co-located with the antenna port of interest with respect to the one or more large-scale channel properties. As a result of using the quasi co-located antenna ports, estimation of the one or more large-scale channel properties is substantially improved.

    Abstract: The present disclosure relates to methods and to a wireless device, 10, 20, for enabling device-to-device communication. In particular the present disclosure relates to a method, performed in a radio node (110, 130), of assigning resources for direct control signalling. The method comprises receiving, 51, from at least one further radio node (130), 160, sets of resources for direct control signalling in a respective cell or cluster. The method further comprises assigning, 52, resources for direct control signalling transmission within an area controlled by the radio node (110, 130) based at least on the received sets of resources, and transmitting, 53, to wireless devices (120, 140) controlled by the radio node, a message indicating resources assigned for direct control signalling. The disclosure also relates to the corresponding method in a wireless device (110) and to a radio and to a wireless device implementing the methods, as well as to corresponding computer programs.

    Abstract: Some previously proposed methods for direct control signalling have a limited probability of success in receiving signals. Disclosed herein is a method, performed in a radio node, of assigning resources for direct control signalling. The method comprises receiving, from at least one further radio node, sets of resources for direct control signalling in a respective cell or cluster. The method further comprises assigning resources for direct control signalling transmission within an area controlled by the radio node based at least on the received sets of resources. The method further comprises transmitting, to wireless devices controlled by the radio node, a message indicating resources assigned for direct control signalling.

    Abstract: According to certain embodiments, a method by a wireless device (210, 300) is provided for resource sensing. The method includes acquiring, from a network node (215), an indication of resources associated with a first resource pool. The first resource pool is for use in an exceptional communication with another device. A triggering event associated with signalling from the network node is identified. Based on the triggering event, a need for the exceptional communication with the other device is determined. At least one resource is selected from the first resource pool, and a message is transmitted using the at least one resource selected from the first resource pool.
