摘要： A method is provided in a base station for handling a request from a first user equipment for accessing a service in a radio communications network. The method comprises the steps of receiving a first time interval of an incoming signal comprises a first signal sent from the first user equipment and a second signal sent from the second user equipment, interpreting the first signal as being a possible service access request message preamble, and sending an acknowledgement, that the preamble is detected, to the first user equipment. The method comprises the further steps of delaying the first time interval of the incoming signal, identifying the second signal in the first time interval of the incoming signal during the delay, washing the identified second signal away from the first time interval of the incoming signal during the delay, and deciding whether the possible preamble is a real preamble or not, by analyzing the washed incoming signal.

摘要： A transmitter (20) for a code division multiple access radio access network intelligently preconditions a channel-merged signal which is applied to its amplifier (22) so that the amplifier does not experience, e.g., precipitous power changes. The transmitter (20) comprises an amplifier (22) for amplifying the channel-merged signal at a signal output power; a detector (24) for performing detection of when output power of the channel-merged signal is about to change by a specified amount; and, a noise inserter (26) for adding a noise signal to the channel-merged signal in dependence upon the detection. Insertion of the noise smoothes an edge of the power change curve and thereby averts stress for the amplifier.

摘要： The invention relates to a method for reducing the number of uplink interference peaks during soft handover from a radio base station (RBS A) providing a source cell (12) to a radio base station (RBS B) providing a target cell (13) in a cellular mobile communication system. The invention also relates to radio base station (RBS) and a radio network controller (RNC) specifically designed for carrying out the method. The RNC orders RBS B of the target cell to set up a link to a mobile (MS) involved in the soft handover procedure. Further the RNC orders the mobile to start listening for RBS B of the target cell and to synchronize to RBS B. RBS B synchronizes with the mobile in a downlink (6) but not in the uplink. The invention is characterized in that the RNC orders RBS A to set a RF transmission power floor below which its transmission power must not fall when the mobile receives RBS B in the target cell stronger than RBS A and perceives the signal in the downlink from RBS B too strong. Further the RNC orders RBS A to set said floor active for a predefined period of time.

摘要： A control node (26) of a radio access network (24) comprises a soft handover unit (62) and a power control unit (50). The soft handover unit (62) controls a soft handover procedure wherein a user equipment unit (30) has diversity in radio transmissions with plural radio base stations (28) comprising an active set of base stations. The power control unit (50), during the soft handover procedure, facilitates an adjustment of an uplink power level used by the user equipment unit (30) for uplink radio transmissions to the plural base stations by an adjustment amount. The adjustment amount is determined to promote uplink synchronization for all radio base stations of the active set. In one example embodiment, the power control unit (50) comprises a soft handover power boost function (70) which, during the soft handover procedure, increases the uplink power level used by the user equipment unit (30) for uplink radio transmissions by the adjustment amount. The adjustment amount is preferably a function of a difference between power levels of downlink reference signals of the active set.

摘要： A base station (28) included in a radio access network of a telecommunications system has two diversity antennas (44A, 44B) for a cell/carrier utilized in a sector served by the base station which are respectively involved in transmission of two branches of a radio link signal of the cell/carrier between the base station and a user equipment unit (30). Two branches of signal processing hardware respectively process the two branches of the radio link signal to yield two respective processed branches of the radio link signal. A rake receiver (62, 262) measures the delay difference between the two processed branches of the radio link signal, and uses the measured delay difference for various purposes. For example, some embodiments of the invention use the delay difference between the two branches as measured by the rake receiver to compensate for a delay difference which exists between the two processed branches of the radio link signal. When measuring the delay difference between the two branches of an uplink radio signal, a rake receiver (62) at the radio base station is employed. On the other hand, when measuring the delay difference between the two branches of a downlink radio signal, a rake receiver (262) at test user equipment unit (30T) is employed.

摘要： A digital radio communication system includes processing to jointly mitigate the deleterious effects of fading, time dispersion and interference using interference rejection and diversity combining. The system employs a selection processor for preliminarily reducing the number of signals for interference rejection and diversity combining based on one or more criterion. The system accommodates signals from dual polarized antennas. In one particular embodiment, the system performs interference rejection and diversity combining by separating a received signal into its in-phase and quadrature components.
