Patent number: 10091717Abstract: A method includes determining information about a radiation pattern of a radar beam that uses a bandwidth. Based on the information, a determination is made whether a channel using at least a portion of the bandwidth is or is not available for access by mobile devices. A transmission is performed to the mobile devices of one or more specific broadcast frames configured to advertise whether the channel is or is not available for access by the mobile devices. Another method includes receiving one or more specific broadcast frames configured to advertise whether a channel is or is not available for access, wherein the channel uses at least a portion of bandwidth used by a radar beam. The channel is or is not accessed based on the one or more specific broadcast frames. The access can be contention-based or contention-free. Apparatus and program products are also disclosed.Type: GrantFiled: November 14, 2013Date of Patent: October 2, 2018Assignee: Nokia Technologies OyInventors: Chittabrata Ghosh, Klaus F. Doppler

Patent number: 9344916Abstract: 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.Type: GrantFiled: January 8, 2015Date of Patent: May 17, 2016Assignee: Nokia Technologies OyInventors: Taejoon Kim, Sayantan Choudhury, Klaus F.

Patent number: 9072060Abstract: 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.Type: GrantFiled: June 3, 2009Date of Patent: June 30, 2015Assignee: Nokia Technologies OyInventors: Klaus Hugl, Cassio Barboza Ribeiro, Klaus F.
