摘要： A method for transmitting packets in a wireless communication network includes taking into consideration an antenna mode prior to transmission. The method includes determining a transmit antenna mode for a transmission between the node and at least one other node; when the transmit antenna mode is omni-directional, broadcasting a transmission schedule for the transmission omni-directionally; and when the transmit antenna is beamforming directional, broadcasting a transmission schedule for the transmission directionally on one or more transmitter beams. The method optionally can also take into consideration an antenna mode of a receive antenna between the node.

摘要： Each node in a wireless communication network adds information in hello messages wherein the information comprises the number of hello messages received at the node from a plurality of nodes. Also, the nodes are configured to determine the node density based on additional information extracted from the received hello messages. For example, a first node in the wireless communication network receives a hello message from a second node, wherein the hello message comprises additional information indicating at least a number of hello messages received by the second node from a plurality of nodes in the wireless communication network. The first node extracts the additional information from the received hello message and based on the extracted additional information, the first node determines at least one channel performance metric. Based on the at least one channel performance metric the first node determines density of neighboring nodes in the wireless communication network.

摘要： A method (10 or 40) or system (200) of predictive sensing of periodic intermittent interference (PII) can include the measuring (12) of energy on a channel for an indication of PII, determining (14) if a channel is currently in a PII on-cycle, and adjusting (16) a clear channel assessment threshold to a new threshold for improved sensitivity of the PII on-cycle. If a current energy level on the channel is below the new threshold and if a previous on-energy characteristic suggests that the current energy level will remain below the new threshold for a predetermined minimum period of time, then a clear channel indication can be provided (20). A busy channel indication is provided (45) when either the current energy level is above the new threshold or the previous on-energy characteristic suggests the current energy level will not remain below the threshold for predetermined minimum period of time.
