A wireless transmission control capability may be used to control downlink (DL) transmissions for a set of wireless user devices or for an individual wireless user device. A DL transmission control capability for a set of wireless user devices may include receiving DL channel operating parameter information associated with a set of cells, determining DL channel operating parameter distribution information based on the DL channel operating parameter information, and determining default DL channel operating parameter information for the set of cells based on the DL channel operating parameter distribution information and a target associated with the set of cells. A DL transmission control capability for an individual wireless user device may include determining radio link layer (RLL) retransmission information associated with a wireless user device and determining, based on the RLL retransmission information associated with the wireless user device, whether to modify an attribute of the wireless user device.

Wireless transmission control for improved aggregated cell throughput capacity and signaling reliability

A method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network, a base station, user equipment, a radio network controller and computer program products are disclosed. The method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network comprises the steps of: preconfiguring the user equipment to support transmissions over a plurality of transport channels of the radio bearer, the plurality of transport channels being associated with a communication state of the user equipment, each of the plurality of transport channels being mappable with logical channels of the radio bearer, the logical channels providing information to be transmitted by the transport channels; and remapping the logical channels onto a different one of the plurality of transport channels in response to a message transmitted between the base station and the user equipment, the message indicating the different one of the plurality of transport channels to be used to support the transmissions between the base station and the user equipment. This approach enables the user equipment or base station to select a transport channel to carry the information from the logical channels autonomously of other network nodes within the network, such as, for example, the radio network controller. By avoiding the need to involve other network nodes in the reselection of the transport channel, rapid changes in the transport channel can be made based on knowledge of the current conditions within either the base station or the user equipment. This approach enables fast switching of the transport channel to improve the performance of the network.

Configuring transmissions by remapping the logical channels onto different one of the plurality of transport channels

A method and system in which a UMTS base station determines if any UE has re-acquired a common Enhanced Dedicated Channel (E-DCH) resource, and responsively transmits a indicator toward an RNC that is adapted to cause the RNC to recognize the beginning of a new transmission session so that the RNC may responsively perform appropriate actions such as flushing the TSN re-ordering queue, restarting a MAC-is re-ordering algorithm and the like.
