摘要:
The present invention provides a method for reporting load measurements. The method may include providing information indicative of a first load associated with at least one first channel type to a first scheduling unit. The first load represents a difference between a second load associated with at least one second channel type and a third load.

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.

The present invention provides a method of wireless telecommunication is provided. The method includes accessing a plurality of first data packets having a first size, accessing at least one second data packet having a second size, the second size being larger than the first size, forming a plurality of third data packets comprising portions of the at least one second data packet based upon the first and second sizes, and selecting at least one of the plurality of first data packets based upon the plurality of third data packets.
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:
The present invention provides a method of wireless communication involving at least one mobile unit and at least one base station configured to transmit data over first and second data channels and corresponding first and second control channels. The method includes accessing control information associated with data to be transmitted over the first data channel and mapping the control information to a portion of the second control channel.

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:
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.

In one embodiment, a target scheduling grant for a user is generated based on the uplink resource consumed by a plurality of users, and a scheduling grant for a user is generated based on the target scheduling grant and the uplink resource consumed by the user. More specifically, in one embodiment, a scheduling grant is generated for the user based on the target scheduling grant, the uplink resource consumed by the user, and a reference scheduling grant.
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.
