name: PCCPCH
full_form: Primary Common Control Physical Channel
context: In this approach, multiple PCCPCH channels are provision in N = 2 or N = 4 scenarios. These secondary PCCPCH channels use the same spreading factor and power as standard PCCPCH channel in normal UMTS system. Two cases of N = 2 and N = 4 are discussed in this subclause. 6.1.1.2.2.1 Time-dilated UMTS N=2 For time-dilated =2, the multiple PCCPCH mechanism consists of using a total of two SF=256 PCCPCHs in order to support the same BCH user data rate as normal UMTS (i.e., 12.3 kbps). Since two SF=256 PCCPCHs are required, 3 dB more power must be allocated to the time-dilated =2 broadcast channel. As an alternative to two SF=256 PCCPCHs, a single SF=128 PCCPCH could be used. Table 6.1.1.2.2.1-1 lists the time-dilated =2 time dilation solution BCH parameters if two SF=256 PCCPCHs are used.

description: The Primary Common Control Physical Channel (PCCPCH) is a type of channel used in Universal Mobile Telecommunications System (UMTS) networks. It carries control information and is essential to the network's architecture. The context mentions multiple PCCPCH channels used in scenarios with N=2 or N=4, where secondary channels share the same spreading factor and power as standard PCCPCH channels.
explanation: The term 'PCCPCH' is classified as a Channel because it functions as a communication pathway for control information within UMTS networks. The context emphasizes its role in carrying control data and how multiple PCCPCH channels are utilized in different network configurations.
