摘要： Method, frame definitions (300 400 500 700 800 1000 1200 1300 1400) and system for transmission of an aggregation of packets which includes a plurality of Medium Access Control (MAC) Protocol Data Units (MPDUs) or PLCP (Physical Layer Convergence Protocol) Protocol Data Units (PPDUs) intended for one or several receivers and transmitted at one or several different Physical (PHY) rates. In some aspects of the invention, a pre-amble, rsp. mid-amble (415.i 515.i 715.i 815.i 1015.i 1215.i 1315.i) is transmitted in-between each or between multiples of MPDUs or PPDUs allowing receiver devices to go into sleep mode and wake-up during the aggregate or packet burst. Furthermore, information is transmitted at the beginning of the aggregate/packet burst, which allows devices to deduce the position of MPDUs/PPDUs or multiples of MPDUs/PPDUs in the aggregate. MPDUs or PPDUs are grouped in order to enable efficient sleep times of the receiving devices. The receiving devices decode the information at the beginning of the aggregate/burst, fall into sleep-mode and wake up shortly before their packets have to be received.

摘要： A fast method for allocating those channels or subcarriers of a multicarrier network to an ahead lying transmission is to let a transmitting terminal and a receiving terminal which intend to access the medium determine the status of the channels or subcarriers that are within their reception range and send a signal indicating the determined status to the corresponding terminal which will select those channels or subcarriers for the eventual transmission which fit best. Other terminals within the transmission range of the transmitting or the receiving terminal respect the reservation and wait for the current transmission to find out which channels or subcarriers are actually used.

摘要： The subnets of a radio network are separated by different scrambling codes. A signalling frame comprises information concerning the spreading code used on the neighbouring or second subnet which can therefore be reserved for a multi hop connection in the first subnet as well. Therefore, in the easiest case the forwarding device only needs to change the scrambling code of the data flow to that of the following subnet and can keep the same spreading code.

摘要： A system and method for selective data transmission is described. The system includes a sender S and a plurality of receivers (R1-R4). The sender has associated encryption means (24) comprising a plurality of base keys (k1-k4). The receivers (R1-R4) each have associated decryption means (34) each comprising a receiver set of keys, where each receiver set of keys is a subset of the base keys (k1-k4). For secure, selective transmission of data to a first, authorized group of receivers the encryption means are configured to encrypt the data recursively with at least two of said base keys, which are all comprised in the receiver sets of the authorized group of receivers, and where at least one of these keys is not comprised in each receiver set of the non-authorized group of receivers.
