摘要： The invention relates to a method for determining the transmission quality in a transmission system. The aim of the invention is to allow for an as fast a measurement as possible of the bit error rate in a transmission system, especially a mobile radio system. To this end, a mobile station (2) that interlinks data received by a base station (1) or a test device via a downlink channel (DL) at least partially in such a manner that the resulting linkage or combination result is transmitted back to the base station (1) via an uplink channel (UL). The base station (1) is thus enabled to precisely and quickly measure the bit error rate of data transmission via the downlink channel (DL) and the uplink channel (UL) even at unsymmetrical transmission rates.

摘要： A method and a system for transmission of data packets between base stations and mobile stations in a mobile radio system includes transmitting each of the data packets in time frames having a fixed number of timeslots, and a mobile station transmitting data packets in a plurality of successive timeslots. In the method and system, while the mobile station is connected to a present base station, a transmitting unit of the present base station transmitting control data packets or no data packets to the mobile station during predetermined time frames while the mobile station is connected to the given base station, and respectively making available to a receiving unit of the mobile station a time interval longer than a predetermined time frame for receiving synchronization data packets and/or measuring signal levels of adjacent base stations.

摘要： The invention relates to a method for transmitting data bits (B) in a communications system. Said bits are allocated to a communications connection and are present in a sequential manner. Transmission channels (Chi) which have been separated according to a CDMA method are provided in the communications system. An individual spread code (SCi) is allocated to said channels respectively. The inventive method comprises the following steps: C>=2 of the transmission channels (Chi) are allocated to the communications connection. Consecutive bits (B) are combined to form bit groups (BG), whereby each group is provided with at least one bit and M bits at the most. Several bit groups (BG) are allocated to each transmission channel (CHi) in such a way that bit groups that were adjacent before allocation are allocated to different transmission channels after the allocation. M>=1 consecutive bits (B) of the bit groups (BG) allocated thereto are combined to form symbols (SY) for each transmission channel (CHi). The symbols (SY) are spread by means of the spread code (SCi) of the respective channel and the spread symbols (SYS) are sent.

摘要： A method for synchronizing a base station to a mobile station includes transmitting a signal sequence K(i) of length n from the base station to the mobile station. The signal sequence K(i) is formed by repeating a second signal sequence element K 2 (k) of length n 2 n 1 times. The second signal sequence is modulated with a first signal sequence element K 1 (j) of length n 1 . In the method, n 1 is equal to n 2 and i, j and k are integers.

摘要： The invention relates to the concept of abandoning the fixed time slot of a common channel and, instead, of transmitting in a temporally synchronous manner the common channel to channels dedicated to that connection to which the common channel is currently assigned. A particular advantage of this solution that is to be used especially in the downlink direction from a UMTS radio communications system consists of carrying out, in particular, a soft combining for the data which is simultaneously transmitted with the data of the dedicated channel, thus being able to guarantee the same transmission quality during the exclusive use of dedicated channels.

摘要： The control method involves operating with a receiver (1) which can be switched by a controller (2) to receive data packets from the neighbouring base stations, during the idle time frames. All the possible training sequences are stored in a memory (3). If the controller processes the signals relatively slowly so that real-time reception is impossible, the data packets from each base station are held in another memory (4) for evaluation. The deinterleaving memory is not used when the mobile receiver is in readiness, and hence it can be used for buffer storage of the data packets.
