    摘要： The invention discloses a method for use in a wireless communications system with a plurality of broadcasting nodes, comprising the step of enabling one node in the system to function as a central node in said system and letting said node enable measurements on at least one frequency in a frequency band used by the system. Said measurements are carried out to detect if said at least one frequency is being utilized by a transmitter foreign to the system. Preferably, the measurement is enabled by means of the node transmitting a message to other nodes in the system, said message being a message pre-defined within the system as a message prohibiting all nodes from transmitting during a certain interval, said message being transmitted after the system has been detected by the node to be silent during a predefined interval between frame transmissions from the nodes in the system.

    摘要： Interference Measurements in a Wireless Communications SystemA method and a transmitting unit for performing an interference measurement in a multiple access wireless communications system utilizing a carrier sensing technique is described. In accordance with the carrier sensing technique, it is monitored during a sensing period (Tmin) if a carrier is idle. A continuous or quasi-continuous interference measurement is performed on the carrier during a measurement period (TM) which is typically longer than the sensing period (Tmin). While performing the interference measurement, pulses are transmitted on the carrier such that an interval between the end of a pulse and the beginning of the next pulse is typically shorter than the sensing period (Tmin). The interference measurements preferably relate to detection of interference from radar signals or radar like signals.

    摘要： In a packet transmission system, especially wireless transmission system, where data is transmitted in packets at different error protection levels and where the error protection level of one packet (=the succeeding packet) may differ from the error protection level of a preceding packet without providing code termination between the said preceding and the said succeeding packet the performance may degrade in case a different error protection level is used by the preceding packet and the succeeding packet. The invention proposes in these cases to insert a supplementary packet between the preceding and the succeeding packet whereby the error protection level of the supplementary packet is higher than the lowest error protection level that is used either by the preceding or the succeeding packet.

    摘要： It was surprisingly found that a-trioxopyrimidine-cyclodextrin-complex formed of a trioxopyrimidine derivative represented by the below-described formula (I) and a water-soluble cyclodextrin (further abbreviated as CD) exhibits enhanced water solubility, excellent stability, and low topical stimulation and is useful as a therapeutic agent. Accordingly, the present invention provides a trioxopyrimidine-cyclodextrin complex formed of a trioxopyrimidine derivative or a salt thereof and a cyclodextrin, preferably α-, β- or γ-cyclodextrin or a water-soluble cyclodextrin derivative (water-soluble being defined as a solubility of at least 0.5 gr/100 ml water at 25° C.), wherein the trioxopyrimidine derivative is represented by formula (I). It was furthermore found that such a trioxopyrimidine complex with cyclodextrin and an adjuvant such as L-lysine or L-arginine show improved water solubility and bioavailability, excellent stability, and low topical stimulation and is useful as a therapeutic agent.
