context: includes a DCH Information IE with multiple DCH Specific Info IEs, then the DRNS shall treat the DCHs in the DCH Information IE as a set of co-ordinated DCHs. If the DCH Specific Info IE includes the Unidirectional DCH Indicator IE set to âUplink DCH onlyâ, the DRNS shall ignore the Transport Format Set IE for the downlink for this DCH. As a consequence this DCH is not included as a part of the downlink CCTrCH. If the DCH Specific Info IE includes the Unidirectional DCH Indicator IE set to âDownlink DCH onlyâ, the DRNS shall ignore the Transport Format Set IE for the uplink for this DCH. As a consequence this DCH is not included as a part of the uplink CCTrCH. [FDD â For each DCH which do not belong to a set of co-ordinated DCHs, and which includes a QE-Selector IE set to âselectedâ, the DRNS shall use the Transport channel BER from that DCH for the QE in the UL data frames. If no Transport channel BER is available for the selected DCH, the DRNS shall use the Physical channel BER for
description: A Dedicated Channel (DCH) is a type of channel used in telecommunications to transmit data between network elements. It refers to a specific communication path within the network that can be either unidirectional or bidirectional. The DCH Information IE and DCH Specific Info IE provide details about the characteristics of these channels.
explanation: The abbreviation 'DCH' is classified as a Channel based on its usage in the context, which describes it as a communication path with specific properties such as being unidirectional or part of a set of coordinated channels. The mention of Transport Format Set IE and Physical channel BER further supports this classification.
