摘要： A method is provided for transmitting a message comprising one or more preambles and a message body from a user equipment device to a network entity. The method includes determining whether it is allowed to transmit a first preamble of the message to the network entity in an immediately available time slot of a random access channel, transmitting the first preamble if it is allowed, and transmitting the message body if a positive acknowledgement to the preamble is received from the network entity on another channel. The user equipment device may determine transmitting the preamble invariably, based on a persistence value or an indication received from the network entity, based on whether the device has not transmitted on the random access channel for longer than a predetermined, or based on whether the device has not transmitted on the random access channel for longer than a random time period.

摘要： The invention relates to an optical access telecommunication network using the O-CDMA multiplexing comprising at least one local exchange unit (LE) being connected with a variety of network terminals (NT) via a passive optical network which has a splitting/combining unit for downstream splitting up the data traffic to be received by the respective network terminals (NT) and for upstream combining the signals transmitted from the network terminals (ONU/NT) into one single data stream to be received by the local exchange unit. Passive optical filter means (OCF) are arranged between the splitting/combining unit and the network terminals (NT), the filter means using individual codes each of which being allocated to a respective network terminal (NT), thus filtering out the data traffic exclusively associated with the respective network terminal (NT).

摘要： A cognitive radio determines a frequency channel of a spectrum, determines from a locally stored association of individual channels to either of at least two categories (e.g., in use and backup, other is a third category) a selected category for the determined frequency channel. From the selected category is determined a time at which to sense the determined frequency channel. The determined frequency channel is then sensed at the determined time and results of the sensing may be transmitted. Timers may be associated with each of the categories and adjusted based on density of cognitive nodes. A timer for the in use category is shortest, a timer for the other category is longest, and a timer for the backup category is between shortest and longest.

摘要： The invention is related to coding and decoding data, more particularly in microwave radio link systems. According to the invention, the sequence of data to be encoded at a transmitting end is split into at least two blocks, if the sequence is longer than a first predetermined length M. The splitting is performed so that the length first block is equal to the first predetermined length M. If the remaining sequence is shorter than a second predetermined length N, the second block comprises all of the remaining sequence. If the remaining sequence is longer than the second predetermined length N, the length of the second block is found by subtracting from the length of the remaining sequence the highest integer multiple of the second predetermined length, and the rest of the sequence is split into blocks of length N. If the sequence is shorter than the first predetermined length M, only one block is produced, and the sequence is padded with dummy values to form a sequence of length M. If the sequence is exactly M units long, the first and in that case the only block comprises the whole sequence. The blocks are then separately encoded with the desired coding function.
