    Abstract: Method and apparatus for minimizing the processing delay incurred by an IC receiver (32) over conventional receivers (20) in a CDMA cellular system are disclosed. The method and apparatus involve operating the conventional receiver (20) and the IC receiver (32) in parallel to each other. Data from the conventional receiver (20) are then used to supplement data from the IC receiver (32) in order to minimize the delays incurred by the IC receiver (32).

    Abstract: A system and method for improving the accuracy of a location estimation measurement within a telecommunication system is disclosed. Transmissions from surrounding base transceiver systems (12A, 12B, 12C, 12D) are received by a reference location device (12) and any inter-base transceiver system timing differences resolved. A location estimate of the mobile station (10) within the telecommunications system is then obtained.

    Abstract: A method for determining whether a zero rate or non-zero rate transmission has occurred, in a variable spreading factor CDMA system, which provides the solution to the problem of de-spreading received signals with incorrect spreading codes and reducing processing delays, is presented. The method utilizes information determined from the received signals, which include control and data channel information, to determine whether a zero rate or non-zero rate transmission has occurred, and generating the correct spreading factor based on that determination. The method is based in a spreading factor detector, which is subsequently able to be utilized in several types of multiple access interference cancellation receivers, which utilize interference cancellation techniques.

    Abstract: The invention is concerned with a radio receiver station, a multi-user interference cancellation unit and a multi-user cancellation method in a system with several transmitting radio stations. In the method, a radio sign al is received as a sum of the signals from at least two of the transmitting radio stations in the system. Interference from at least two of the transmitting radio stations is cancelled. The interfering signals from at least some of the transmitting radio stations are processed in at least two separate operations in one or more stages, the result of each separate operation being taken into consideration in the estimation of the desired modulated signal sent to the receiver. Preferably, a part of the interfering signals is processed in one of the separate operations, while the rest of th e interfering signals are processed in the other separate operations. If the cancellation is carried out in more than one step, the cancellation results of the first cancellation stage are used in the second interference cancellatio n stage, the method being correspondingly continued in the possible further cancellation stages.

    Abstract: The present invention relates to sectorization of a cellular CDMA-system. Each sectorized cell (CELL) in the CDMA-system comprises a number of antenna sectors (AS1-AS8) having overlapping regions. Each cell is allocated a number of at least two different pilot channels (P1, P2). Two antenna sectors having a common overlapping region are not allowed to use the same pilot channel. At least one of said pilot channels (P1, P2) are reused within the cell, by at least two antenna sectors with no common overlapping region. The antenna sectors that use the same pilot signal are constituting a logical sector (LS1, LS2). A mobile station can communicate with the base station in a cell by using one or more antenna sectors within one or more logical sectors. If a mobile station communicates with the base station within a number of antenna sectors within the same logical sector, no softer handoff is required between the antenna sectors.
