Multi-mode UE issues; categories, principles and procedures
This 3GPP Technical Report identifies multi-mode User Equipments categories. This technical report also describes the general principles and procedures for the multi-mode operation standardised in the 3GPP specifications. In particular, this TR is focused on a type 2 UE, as defined in Clause 4 in the present report. This type of UE can when utilising one mode, perform monitoring of another mode and report it utilising the current mode. This type of UE does not support simultaneous reception or transmission through different modes.
The scope of this TR is the type of terminal implemented with at least the following modes:
- UTRA FDD and/or TDD mode
- GSM mode
Regarding the GSM mode, it encompasses the capabilities offered by the GSM technical specifications, e.g, Circuit Switched and Packet Switched services using either GMSK or 8-PSK modulation in the frequency bands specified in the GSM specifications.
The present report is built on and references specifications/reports being produced in 3GPP or within other relevant foras e.g. ETSI SMG.
