Example text

As a consequence, the transmission power for the control channel can be lowered without risking corruption of the information contained in the TPC. Once user data transmission resumes, the standard slot format is used again and the transmission power used for the control channel is increased again. 2 of [11]) in Combination with Downlink Control Information Transmission Enhancements • CQI reporting reduction: to make the best use of the current signal conditions in the downlink, the mobile has to report to the network how well its transmissions are received.

In the uplink direction, an HSDPA-capable device also has to send a number of different data streams, each with a different spreading code. The first stream is the HSDPA control channel, which is used to acknowledge the correct reception of downlink data packets. In addition, a dedicated channel is required for IP packets transmitted in uplink direction. , a cell change command) and for the uplink direction of an ongoing voice call. 30 3G, 4G and Beyond–Bringing Networks, Devices and the Web Together Finally, the mobile needs to send control information (reception quality of the downlink dedicated channel) to the NodeB.

1 Shared Channels To improve the utilization of the air interface, the concept of shared channels has been (re-) introduced. HSDPA introduces a High-Speed Downlink Physical Shared Channel (HS-DPSCH), which several devices can use quasi simultaneously as it is split into timeslots. The network can thus quickly react to the changing bandwidth requirements of a device by changing the number of timeslots assigned to a device. Thus, there is no longer a need to assign spreading codes or to modify the length of a spreading code to change the bandwidth assignment.
