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.

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.

Medium access control method enhancement

In one aspect the embodiments of the invention provide a method that includes transmitting a first frame comprising a first type of message from a first node for reception by a second node. The first node is associated with a first wireless communication system and the second node is associated with a second wireless communication system. The first type of message includes a first information element for identifying the second node and a second information element for specifying that the first frame is transmitted to initiate a request for simultaneous transmission by the first node and by the second node. The first frame is also received by a third node that is part of the first wireless communication system. The method further includes receiving from the third node a second frame that includes a second type of message. The second type of message identifies the second node and specifies, based on a measurement performed by the third node on the first frame and a measurement performed by the third node on a third frame transmitted by the second node, whether the request for simultaneous transmission is accepted or is not accepted by the third node. The method further includes transmitting a fourth frame that includes the second type of message from the first node for reception by the second node. The second type of message identifies the second node and specifies that the request for simultaneous transmission was accepted by the third node.

Apparatus and method for mode selection for device-to-device communications

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.
