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. | 05-09-2013 |
20130136066 | Medium Access Control Method Enhancement - 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. | 05-30-2013 |
20130176998 | Mechanism For Coexistence Between Wireless Networks - 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. | 07-11-2013 |
20130223306 | Buffered Frames Indication Enhancement To Enable Power Savings - 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. | 08-29-2013 |
20130223377 | Context Transfers And Multi-Band Operation For Wireless Networks - Various example embodiments are disclosed relating wireless networks and relating to context transfers and multi-band operation in wireless networks. In an example embodiment, a multi-band scheduler may be provided for use in a wireless node. The multi-band scheduler may be configured to: receive one or more data units of a flow; assign each received data unit of the flow to a first frequency band of a plurality of frequency bands; determine a band transfer condition for the flow; and perform a context transfer from the first frequency band to a second frequency band for the flow based on the determined band transfer condition. | 08-29-2013 |
20130229988 | Method and Apparatus for Synchronized Channel Access Among Groups - 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. | 09-05-2013 |
20130294427 | Method And Apparatus For Signaling Sequence Root - A first access node of a first network utilizes code sequences, assigned to different user devices, to distinguish at least acknowledgements received in parallel or sequentially from those user devices. The first access node determines from received signaling that a root sequence of the code sequences is in use by a second access node of a second network, then changes that root sequence of the code sequences assigned to the different user devices. In certain examples the access nodes are WLAN access points APs and the acknowledgements are received in response to a group probe/poll. In various embodiments the first AP monitors its neighbors' group probes/polls to learn the root sequences/basic service sets in use in those neighbor networks, or the AP's own stations monitor and send the information in neighbor reports. This latter option can be initiated by the stations themselves, or by the AP. | 11-07-2013 |
20130336234 | Medium Access Control Method - The exemplary embodiments of the invention relate to at least a method including receiving an indication that a first resource allocation to a device to transmit data was insufficient and there is remaining data to transmit by the device, based at least on information associated with the first resource allocation, determining a second resource allocation for the device, and sending the second resource allocation to the device in order to enable the device to transmit the remaining data. Further, there is a method including sending an indication that a first resource allocation to a device to transmit data was insufficient and there is remaining data to transmit, and in response to the sending, receiving a second resource allocation to the device to enable the device to transmit remaining data, wherein the second resource allocation is based at least on information associated with the first resource allocation. | 12-19-2013 |
20140038590 | SETUP OF DEVICE TO DEVICE CONNECTION - 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. | 02-06-2014 |
20150079972 | Method And Apparatus Providing Multi-Level Proximity Indication And Small Cell Discovery - 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. | 03-19-2015 |
