    摘要: This invention applies to a mobile station that is able to determine a required data rate based on data buffer usage. If the data buffer indicates a requirement for a high data rate transmission, the mobile station sends a request to a base station to be assigned multiple parallel code channels. If the multiple parallel code channels are granted, the mobile station uses the channels for transmitting data to the base station until either the data buffer becomes empty, or a base station time-out occurs, or the mobile station is signalled by the base station to reduce its data transmission rate, whichever occurs first. The mobile station of this invention is enabled to autonomously control the data rate during an assigned period for high speed transmission, so as to lower the data rate when needed for the purpose of improving coverage and/or to avoid operating in a power limited condition, thereby degrading link quality. The data rate is lowered by disabling transmission though at least one parallel code channel, and subsequently resuming transmission though the code channel when conditions warrant. This provides a discontinuous transmission (DTX) mode of operation for individual ones of supplemental parallel data code channels.

    摘要: A TDMA cellular radio system and a method of allocating available frequency bands to different cells in a TDMA cellular radio system wherein at least some of the receivers within the system use interference cancellation methods which cancel the effects of co-channel interference in a desired signal. To enable efficient use of interference cancellation and the resulting capacity increase in the system, the frequency bands available for the cellular radio system are allocated to different cells so that groups of adjacent service areas are formed in the system. Each group uses the same frequency band within the service areas, whereby at least one co-channel signal interfering with the desired signal is significantly stronger than other co-channel interfering signals.

    摘要: In packet switched data transfer of the cellular radio system, the control of the transmission power comprises characteristics as well of the closed-loop control and the open-loop control. Before forming the connection and during long pauses between the packets, the terminal device measures the control signal transmitted by the base station and compares its signal power (R0) to the target level (t0), that is included by the base station in the control signal as a parameter. The base station informs in the control signal also the transmission power, whereby the terminal device sets the same power to be its transmission power, corrected by the difference between the target level and the measured quality of the link (t0-R0). In addition, also the measured quality of the link (RXQUAL) is transmitted in the acknowledgment messages of the packets, whereby the transmitting device changes its transmission power so that the quality will be controlled to the certain target level. The biggest step of the change is determined by the length of the packets. In the packet transfer downlink, the base station uses first the maximum power and corrects then its transmission power based on the measuring information included in the acknowledgment messages transmitted by the terminal device.

    摘要: The invention relates to methods, transmitters and transceivers for transmitting a user signal, particularly a speech or video signal on a circuit-switched connection in a cellular radio network when the bit rate of the user signal varies during transmission. The transmitter comprises a source (2) of a variable bit rate user signal, such as speech or video encoder, and a channel encoder (3) and a radio transmitter unit (7) having an adjustable transmitting power. The capacity allocated for the circuit-switched connection corresponds to the maximum rate of the user signal. The channel encoder (3) has, for the maximum bit rate of the user signal, a first, relatively the least efficient channel coding or no channel coding at all, and for each lower bit rate of the user signal a relatively more efficient channel coding that utilizes the capacity of the circuit-switched connection, released by the lower transfer rate, for improving the interference tolerance of the connection. The transmitting power of the radio transmitter unit depends on the channel coding used by the channel encoder so that the transmitting power is reduced with the increased efficiency of the channel coding, while the bit-error-rate remains substantially constant. This results in a lower average power level and thus in a reduced interference level in the cellular network.

    摘要: A signal detection method in a TDMA mobile system with co-channel interference and receivers implementing the method. In the method, a primary signal (r.sub.1) and at least one interfering co-channel signal (r.sub.2 -r.sub.N) are received on the same TDMA channel (F.sub.1, TS.sub.3). The co-channel signals propagate through multipath channels (h.sub.L,1 . . . h.sub.L,N) independent of one another, which provide them with a unique wave form coding. In addition, the co-channel signals have different but known training sequences. The multipath channel estimates of the primary signal (r.sub.1) and the at least one interfering co-channel signal (r.sub.2 -r.sub.N) are determined through the received training sequences. After this, the primary signal is detected by utilizing the transmission channel estimates of both the primary signal and the at least one interfering co-channel signal.
