Abstract: Described herein is a technique for aggregating background traffic packets by the background users instead of performing a random access procedure to request an uplink resource for each new packet. Since the same physical random access channel (PRACH) resources are used for random access procedures by multiple UEs, collisions can occur. The PRACH is expected to operate with very low collision rates, but if the number of users increases, the collision rate increases as well as the error rate. The disclosed technique reduces the collision rate by reducing the number of random access procedures used to transmit background traffic.

Abstract: A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the receive timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.

Abstract: Methods for using a detector to monitor and detect channel occupancy are disclosed. The detector resides on a station within a network using a framed format having a periodic time structure. When non-cooperative transmissions are detected by the network, the detector assesses the availability of a backup channel enabling migration of the network. The backup channel serves to allow the network to migrate transparently when the current channel becomes unavailable. The backup channel, however, could be occupied by another network that results in the migrating network interfering with the network already using the backup channel. Thus, the detector detects active transmission sources on the backup channel to determine whether the backup channel is occupied. Methods for using the detector include scheduling detection intervals asynchronously. The asynchronous detection uses offsets from a reference point within a frame.

The frequency offset estimation range utilized for the current iteration is reduced for the next iteration. A Cell-ID is declared if the Cell-ID is consistently detected not only within a particular iteration on the basis of having detected consistent cell ID information for the first and second halves of a radio frame, but also from iteration to iteration.

Higher layer signaling may be used to activate TTI bundling with implicit signaling then used to dynamically control the actual TTI bundle size used.
