name: CPCH
full_form: Common Packet Channel
context: PDU size for every carrier independenly, - DCH is supported in MC-HSUPA and can be only configured on one uplink carrier, - Non-scheduled transmission is not supported in MC-HSUPA, - Scheduling procedures: - Scheduled transmissions can be sent on any uplink carrier. The resources to be used on each uplink carrier are signalled via Absolute Grants, - for one UE, there is only one E-RNTI for all uplink carriers, - absolute grant is provided specifically to each uplink carrier, - The extended SI structure is introduced for MC HSUPA to report TEBS, HLID, HLBS, UPH of one carrier and the SNPLs of one or more carrier groups to NodeB. - T_SI is maintained per UE and the SI reporting scheme for MC HSUPA is same as that for single carrier HSUPA. - Mobility and measurements: - The reference frequency is introduced for defining intra-frequency cell and inter-frequecy cell, - The mobility procedure for MC-HSUPA should be identical to the legacy mobility procedure based on the reference frequency,
description: The Common Packet Channel (CPCH) is a type of channel in the Universal Mobile Telecommunications System (UMTS) used for transmitting packets of data. It can be configured as either a single CPCH or multiple CPCHs, with varying packet lengths and inter-arrival times. The performance of the CPCH can be evaluated using methods like the idle-random method and compared across different scenarios.
explanation: The text describes the CPCH in terms of its role in data transmission within UMTS, its configurable nature (single or multiple), and performance evaluation metrics. These characteristics align with the definition of a telecommunications channel.
