Abstract: Disclosed are apparatus, methods and computer programs to establish device-to-device communications in a wireless network. A method includes sending an initiation message from a first device to initiate device-to-device communication with a second device; receiving a message indicating a request for setting up radio resources for device-to-device communication; sending a message to the second device, the message including a request to set up resources for device-to-device communication and, in response to establishing device-to-device communication with the second device using the resources, sending an acknowledgment that device-to-device communication is established.

Abstract: In the detailed examples an access point AP assigns each of a plurality of stations to a group, in which at least one group has multiple stations assigned. For each group the AP sets a group-specific medium access interval during which stations who are members of the group are allowed to compete for medium access, and sends a message indicating the group-specific medium access intervals for the respective groups. A station receiving the message determines the group to which it belongs and determines that it is allowed to compete for medium access at least during the medium access interval. Various examples provide options for how the grouping might be made and how the intervals might be dynamically adjusted.

Abstract: A method includes receiving, by an apparatus, a signaling element containing an indication whether there are buffered individually addressed frames for at least one device within a group of devices; determining, by the apparatus, whether the apparatus belongs to a group for which there are no buffered individually addressed frames, based on the indication; and if the apparatus belongs to a group for which there are no buffered individually addressed frames, entering a lower power state without waiting to receive a next signaling element.

Abstract: In accordance with the exemplary embodiments there is at least a method performed with an apparatus of a wireless communication network including sensing information regarding at least one coexisting network, and sending the information in a header of a media access control frame to a network node of the wireless communication network. In addition, in accordance with the embodiments, there is at least a method performed with an apparatus of a wireless communication network including receiving sensing information regarding at least one coexisting network in a header of a media access control frame from at least one device of the wireless communication network, determining, using at least the sensing information, occupancy information regarding one or more coexisting networks of the wireless communication network, and sending the occupancy information to one or more devices of the wireless communication network.

Abstract: The exemplary embodiments provide at least a method of receiving, by a node of a wireless communication network, more than one indication of data required to be sent from devices in the network, determining that provisioning resources to send the data in response to each of the more than one indication exceeds at least one threshold, and based on the determining, sending a probe message including a priority constraint to the devices. Further, receiving, at a device of a wireless communication network, a probe message from a network node of the network, the probe message identifying a priority constraint, sending, by the device, an acknowledgement to the probe message, the acknowledgment indicating that the device has data to send which meets or exceeds the priority constraint identified in the probe message, and in response to the acknowledgment, receiving from the network node a resource allocation to send the data.

Abstract: The exemplary embodiments enable setting one or more devices of a wireless communication network to be associated with a one or more groups of a plurality of groups based on at least a device type of the one or more devices, receiving at least one indication that one or more devices have data to send, and allocating, one group at a time, resources to the groups associated with the devices with data to send. Further, receiving a probe message from a network node, the probe message identifying one or more groups set to the device based at least on a device type, sending, information to the node, the information providing an indication that data is required to be sent, and in response to the sending, receiving a resource allocation from the node to send the data, wherein the resource allocation is arranged based on the groups set to the device.

Abstract: A method includes receiving a first measurement configuration at a user equipment from a wireless communication network; making measurements using the first measurement configuration; in response to a condition being satisfied resulting from the measurements that are made, transmitting an indication that an allowed small cell has been detected; receiving a second measurement configuration at the user equipment from the wireless communication network; and making measurements of the allowed small cell using the second measurement configuration, where the first measurement configuration results in measurements being made less frequently than measurements made in accordance with the second measurement configuration. An apparatus configured to perform the method is also disclosed.

Abstract: A network determines that a first radio node communicating on a radio resource with a second radio node is interfering with a third radio node communicating on the radio resource with the network. The network manages the interference by controlling transmit power of at least one of the first radio node and the third radio node. It may be by sending a command that indicates an amount by which the first or second radio node is to decrease its transmit power; and/or that indicates an amount by which the third radio node is to boost its transmit power. The network can measure a sounding signal it triggers from the first radio node, measure and compare to a threshold that guarantees a QoS for the third radio node, and compute appropriate backoff or boost values. The first and second radio nodes may be using device-to-device communications or a femto network.
