    Abstract: A METHOD FOR PROCESSING MULTIPLE DATA SERVICES OVER A COMMUNICATIONS LINK BETWEEN A MOBILE STATION AND A BASE STATION IS DISCLOSED. A RLC/MAC PROTOCOL LAYER OF THE COMMUNICATIONS LINK BETWEEN A MOBILE STATION AND A BASE STATION RECEIVES A PLURALITY OF RADIO BEARER SERVICES EACH INCLUDING AT LEAST ONE SERVICE PROVIDED BY THE MOBILE STATION. THE PLURALITY OF RADIO BEARER SERVICES ARE PROCESSED IN SUCH A MANNER THAT SERVICES HAVING SUBSTANTIALLY SIMILAR QUANTITY OF SIGNAL REQUIREMENTS ARE COMBINED FOR TRANSMISSION ON A SINGLE LOGICAL CHANNEL. DATA WITHIN THE TRANSMISSION BLOCKS MAY BE PRIORITIZED TO ENABLE FLEXIBLE CONTROL OF TRANSMISSION RATES.

    Abstract: An optimal data block size is determined for use in transmitting data at variable rates over a communications link in predetermined time intervals, where each predetermined time interval has the same time duration. Rather than varying data block size according to changes in transmission rates, which adds unnecessary complexity, the data blocks all have the same fixed size, i.e., the same number of data bits in each block. That fixed data block size is determined so that for all of the available data transmission rates, each predetermined time interval is fully occupied with useful information. The fixed data block size is determined based on a maximum frequency at which the transmission rate may change on the communications link and a lowest available transmission rate. Preferably, the fixed size of each data block is limited by predetermined maximum and minimum data block sizes in order to reduce the number of bit errors per data block, maintain a certain data throughput, and limit the amount of overhead bits relative to the number of payload bits for each data block.

    Abstract: Methods of controlling the power levels of transmitted signals in telecommunication systems are described. A user may be assigned a plurality of radio bearers associated with a plurality of physical channels for communicating with a radiocommunication system. A fast power control loop monitors a reference channel and adjusts transmit power in accordance with an SIR target value. A plurality of slow power control loops adjust the SIR target value and also provide offset transmit power values associated with each physical channel to adapt the transmit powers in accordance with varying quality requirements between radio bearers.

    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.
