摘要： 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.

摘要： 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.

摘要： 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.
