name: TD-SCDMA
full_form: Time Division Synchronous Code Division Multiple Access
context: The W1-C signalling bearer provides the following functions: - Provision of reliable transfer of W1AP messages over the W1-C interface. - Provision of networking and routeing function. - Provision of redundancy in the signalling network. - Support for flow control and congestion control. The protocol stack for W1-C Signalling Bearer is shown in figure 4.1-1 and details on each protocol are described in the following clauses. Figure 4.1-1: W1-C signalling bearer protocol stack The Transport Network Layer is based on IP transport, comprising SCTP on top of IP.
description: Time Division Synchronous Code Division Multiple Access (TD-SCDMA) is a telecommunications technology that enables multiple access to a single radio channel. It is one of the air interface technologies used in UMTS (Universal Mobile Telecommunications System). TD-SCDMA is being considered for coexistence with E-UTRA TDD (Evolved Universal Terrestrial Radio Access Time Division Duplexing) in MSR (Multi-Standard Radio) mode, where minimizing interference between the two technologies is crucial. The context highlights the importance of UL:DL alignment and periodicity in defining RF requirements for TD-SCDMA and E-UTRA TDD coexistence.
explanation: TD-SCDMA is classified as a Technology based on its description as an air interface technology used in UMTS, and its consideration for coexistence with E-UTRA TDD in MSR mode. The context provides details about the technical aspects of TD-SCDMA, such as UL:DL configurations, periodicity, and RF requirements, which further supports its classification as a Technology.
