摘要:
An exemplary method of controlling communications that may include high speed downlink packet access (HSDPA) traffic includes setting a first power limit below an allowable power limit. A second power limit is set that is below the first power limit. A determination is made whether there is any HSDPA traffic. The first power limit is selected for non-HSDPA traffic when there is no HSDPA traffic. The second power limit is selected for non-HSDPA traffic when there is HSDPA traffic.

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 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.
