Embodiment Construction

[0028] Figure 2 illustrates in schematic form the elements of a wireless communication network required for understanding the invention. The radio network controller RNC2 communicates with the packet-switched core network CN4 for receiving and sending packet data from an IP source 6 . The radio network controller controls a plurality of Node B8s, two of which are shown in FIG. 2 .

[0029] Each Node B manages a network cell or sector in which a number of user equipments are located, two of which are shown in FIG. 2 UE1 , UE2. Each user equipment is connected with its Node B via a radio interface comprising in each case an uplink channel 10 and a downlink channel 12 .

[0030] The uplink channel 10 in this particular case comprises an enhanced data channel corresponding to the enhancement of the uplink DCH for data packet services in Release 6 of 3GPP, which is in particular related to TR25.896 Feasibility Study for Enhanced Uplink for UTRAFDD corresponds to TF25.808 FDD Enha...

Abstract

A method of scheduling transmission of data in a wireless communication network comprising: establishing a data channel for transmitting user data from a user equipment to a network entity, establishing a signalling channel for transmitting signalling data from a user equipment to a network entity, transmitting over said signalling channel from the user equipment a first rate request message requesting additional resources from the network for transmission of data at an increased data rate over said data channel, maintaining said signalling channel for a period awaiting a rate grant message, and transmitting a second rate request message over said signalling channel during said period.

Description

technical field [0001] The present invention relates to scheduling data transmissions in a wireless communication network. Background technique [0002] As is well known, wireless communication networks provide links for real-time services such as voice calls (circuit switched) and also for data traffic which is generally transmitted in packets and does not require real-time transmission. The network resources given to packet data services are network resources not used by circuit switched applications for voice, video, etc. [0003] Existing wireless communication networks for Wideband Code Division Multiple Access (WCDMA) communications operate by using multiple Node Bs that communicate wirelessly with user equipment in the form of mobile terminals, which may be mobile phones or any other kind of mobile communicator. Communication between the user equipment and the Node B is over a wireless interface. The operation of the Node Bs is controlled by a Radio Network Control...
