    Abstract: In a time division multiple access (TDMA) based cellular radio telecommunications system, system performance is improved by adjusting the transmit power associated with certain downlink signals during a corresponding timeslot, and in such a way that the power adjustment resembles that of a typical fading event, in terms of both time of occurrence and rate of occurrence (e.g., dB per msec). During the same timeslot, the transmit power is associated with other downlink signals is maintained at a substantially constant level. More particularly, the transmit power associated with a downlink signal is maintained at a substantially constant level if the power level does not sufficiently provide adequate signal quality for the corresponding mobile station in the presence of fading. In contrast, the transmit power associated with a downlink signal may be adjusted (e.g., attenuated) in such a way that it resembles that of a typical fading event if the transmit power associated with the downlink signal provides more than adequate signal quality for the corresponding mobile station, despite the power level adjustment and the presence of fading.

    Abstract: The present invention is related to a Rake receiver (R1) for receiving a radio signal and to a searcher (S8a, S8b) for estimating the delay profile of one or more radio links. The searcher includes means for estimating delay profiles in separate windows. The searcher is arranged for being switched into a single window mode or alternatively into a multiple window mode. In single window mode the delay profiles of separate radio links are estimated in the windows, while in multiple window mode two or more windows are allocated adjacent in time for estimating the delay profile of the same radio link. Thereby, the use of the resources of the searcher can be adapted to the radio environments in which the searcher will be used. The Rake receiver comprises fingers that are grouped into two sets. Within a set of fingers the propagation paths are time aligned. The output from the two set of fingers are time aligned and then combined.

    Abstract: A cellular communications network includes a plurality of cells whose base stations (122) have smart antenna capabilities and conventional sector antenna capabilities. At mobile station (142) call setup, the call is initially set up on a sector antenna supported, looser frequency reuse plan assigned, measurement traffic channel frequency provided by the serving base station. Higher quality direction of arrival angle measurements (210) are then made at the serving base station to identify a particular smart antenna narrow beam which could serve the mobile station. A replacement frequency supported by that narrow beam is then selected (214), and an intra-cell handoff of the call is ordered (216). In the event mobile station location information is needed (e.g., based on the call type or call priority), neighbouring base stations are instructed (304) to make (306) and report (308) on direction of arrival angle measurements towards the mobile station. The reported angles are then processed (310) using triangulation (or other suitable) techniques, in view of known base station geographic location, to determine an approximate location of the mobile station.

    Abstract: The present invention is directed to cellular systems and methods for providing a multi-beam antenna configuration (50) within a base station without utilizing duplex filters. The multi-beam antenna configuration (50) of the present invention produces overlaid beams (1, 2, 3, 4) in both the uplink and downlink to cover the same area. Each beam (1, 2, 3, 4) has orthogonally oriented polarization directions (e.g., linear polarized slanted +45E) for the uplink and downlink. Adjacent uplink beams (1, 2, 3, 4) shall also have shifted polarization directions in order to attain polarization diversity between different beams (1, 2, 3, 4). In order to implement this polarization configuration, for each beam (1, 2, 3, 4), there is a selective filter (60) in front of the low noise amplifier (40a) for the uplink, and no duplex filter in front of the amplifier (40b) in the downlink direction.

    Abstract: In a Time Division Multiple Access based radio telecommunications system that employs downlink power control, received signal strength information is measured and reported. A downlink data signal is transmitted from a base station to a mobile station during a first timeslot. A control channel signal or a dedicated traffic channel signal having equivalent output power behavior as the control channel, is transmitted from the base station throughout a cell in which the mobile station is operating. At the mobile station, a received signal strength of the control channel signal or the dedicated traffic channel signal is measured. The received signal strength may be measured in period between when the mobile station transmits and receives or in a period between when the mobile station received and transmits. The received signal strength may be measured during the first timeslot or during a timeslot other than said first timeslot. The received signal strength may also be measured during a time period associated with Mobile Assisted Handover (MAHO) measurements, the MAHO list including the control channel and/or the dedicated traffic channel. The received signal strength as measured by the mobile station is reported to the base station. The measured received signal strength is compensated for to obtain signal strength information associated with the downlink data signal received by the mobile station during the first timeslot.

    Abstract: The transmit power of a radio transmitter associated with a transmitting node communicating with a receiving node is controlled based on a propagation delay time associated with communication between the transmitting node and the receiving node. A power control loop is established for controlling a transmission power level for transmitting a signal from the transmitting node to the receiving node. A response time of the power control loop is reduced based on the propagation delay time.
