Abstract: Wireless communication is performed in a wireless network by dividing up a data transmission interval (DTI) within the communication frame into a plurality of time slots based on determining the number of best sector directions from the AP to each STA in the wireless network. Each STA transmits only during this time slot, while the AP uses receiver beamforming and receives only from a single beamforming direction for each of these time slots. A time slot may be used by more than one STA if they are in the same best antenna sector direction from the AP, wherein they contend for access within this time slot.

Abstract: Multi-band signaling is described for reducing signaling overhead in an apparatus and method for communications within a mesh network. The communications involve using two different beacon signals on two different communication channels. Peer beacons are sent using directional millimeter-wave (mmW) communications to provide time synchronization and resource management information to maintain existing links among one or more neighboring peer stations. A separate network discovery beacon is sent over a sub-6 GHz communication channel, to provide mesh network profile information that identifies the mesh network to aid network discovery for wireless communication stations wanting to join the mesh network.

The second information processing device performs control such that the reception of the frame is stopped based on the signal (which is a signal having backward compatibility) serving as an index by which reception of the frame is stopped when the frame transmitted from the first information processing device is received.

Abstract: A method for managing a buffer having a preset byte size for storing files includes determining a file identifier and length of an incoming file. The method includes determining that the incoming file will not fit into a space between a next write location and an end of the buffer. In response to the determination that the incoming file will not fit, the method includes, in a map, deleting each entry corresponding to a file at least partially overlapping the range of the incoming file and adding an entry in the map for the incoming file. The method further includes allocating a contiguous area in the buffer for the incoming file and then moving the next write location to the end of the allocated contiguous area, and receiving packets of the incoming file and storing the received packets into the allocated contiguous area.
