name: DPDCH
full_form: Dedicated Physical Data Channel
context: In this example, DTX bits are not inserted into DPDCH and power adjustment is applied instead. The basic idea is to have more power on the coded block with more coded bits. The final applied DPDCH power is proportional to the number of coded bits. DPDCH power is maintained by power control. Based on packet types, different DPDCH power adjustment is introduced. The concept is similar to Î²d/Î²c in UL. Table 4.2.1.2.8-1 shows a DPDCH power adjustment example. For example, it is assumed X dB Ec/Ior is to be applied on DPDCH in specific slot in absence of DPDCH power adjustment. Based on this table, if packet type is Full, the adjusted DPDCH power is X dB. If the packet type is , the adjusted DPDCH power is (X-6.29), and if the packet type is Null, the adjusted DPDCH power is X-10.4 dB. Table 4.2.1.2.8-1 : DPDCH power adjustment example
description: The Dedicated Physical Data Channel (DPDCH) carries dedicated data traffic between the User Equipment (UE) and the Node B in the Universal Mobile Telecommunications System (UMTS). It transmits user data, control signals, and other information. Power adjustment of DPDCH is crucial for optimal transmission quality and is based on packet types.
explanation: The text describes DPDCH as a channel responsible for transmitting data between network components within the UMTS system. This function aligns with the definition of a Channel entity type.
