    摘要: The present invention relates to a method for transmitting of data frames from user equipment to a base station in a wireless telecommunication network. The method comprises an error control step adapted to retransmit the data frame from the user equipment to the base station, if the received data frame contains errors or if no acknowledge message is received by the user equipment within a predetermined amount of time. The method further comprises a transmission power control step adapted to control a transmission power of the data frames in such a way that the number of retransmissions corresponds to a predetermined number of target retransmission. The number of target retransmission is adapted depending on the traffic load and/or the number of users connected to the base station.

    摘要: Methods of providing power overload control in a communication system having a least one base station serving one or more users of at least one cell are described which may avoid an overload condition in the system. In one aspect, a target signal-to-interference ratio (SIRtarget) may be controlled for inner loop power control implemented by the base station, so as to maintain the loading of the communication system below an overload condition. In another aspect, a target block error rate (BLERtarget) may be controlled for outer loop power control implemented by the base station, so as to maintain the loading of communication system below an overload condition.

    摘要: A radio resource method and apparatus involves allocating transmission channels to and from a node (26) based on the system load requirement. The load requirement is determined from the quality of service requirement which, in turn, is assessed from the data rate, the bit energy to noise power ratio and the signal classification produced by a converter and sorter (38) in response to signal transmission requests. A maximum load generator (40) delivers the maximum load from these parameters. A core calculator and assignor (42) performs a predetermined algorithm on the outputs of the converter and sorter (38) and the maximum load generator (40) and in response thereto controls a channel selector (30) which selects the channels to and from node (26).

    摘要: A method and apparatus are disclosed whereby noise is introduced at one or more base stations in non-HSDPA cells into the uplink signal from one or more user devices. As a result, the apparent quality of the uplink channel in those cells will appear to be lower than the actual quality of that channel. The power control commands issued from the base station to the user device will, therefore, reflect this lower estimated channel quality and, as a result, the user device will follow power control commands from the base station in the HSDPA cell. Therefore, the transmit power of the user device will remain adequate to communicate with the base station in the HSDPA cell and, as a result, the UL and DL in the HSDPA cell will remain synchronized.
