Channel coding |
A reference configuration of the transmission chain is shown in TS 45.001. According to this reference configuration, the present document specifies the data blocks given to the encryption unit.
It includes the specification of encoding, reordering, interleaving and the stealing flag. It does not specify the channel decoding method.
The definition is given for each kind of logical channel, starting from the data provided to the channel encoder by the speech coder, the data terminal equipment, or the controller of the Mobile Station (MS) or Base Transceiver Station (BTS). The definitions of the logical channel types used in this technical specification are given in TS 45.002, a summary is in annex A.
Additionally, the present document describes the characteristics of the coding/multiplexing unit for the Flexible Layer One (FLO) starting from the transport blocks provided by higher layers. An overview of FLO is given in TR 45.902.

Modulation |
|
The modulator receives the bits from the encryption unit, see TS 45.001, and produces an RF signal. The filtering of the Radio Frequency (RF) signal necessary to obtain the spectral purity is not defined, neither are the tolerances associated with the theoretical filter requirements specified. These are contained in TS 45.005.

Radio transmission and reception |
The present document defines the requirements for the transceiver of the pan European digital cellular telecommunications systems GSM.
Requirements are defined for two categories of parameters:
|
| - |
those that are required to provide compatibility between the radio channels, connected either to separate or common antennas, that are used in the system. This category also includes parameters providing compatibility with existing systems in the same or adjacent frequency bands;
| |
| - |
those that define the transmission quality of the system.
|
The present document defines RF characteristics for the Mobile Station (MS) and Base Station System (BSS). The BSS will contain Base Transceiver Stations (BTS), which can be normal BTS, micro BTS or pico-BTS. The precise measurement methods are specified in TS 51.010 and TS 51.021.
Unless otherwise stated, the requirements defined in this EN apply to the full range of environmental conditions specified for the equipment (see annex D).

Radio subsystem synchronization |
|
The present document defines the requirements for synchronization on the radio sub-system of the digital cellular telecommunications systems GSM. However, it does not define the synchronization algorithms to be used in the Base Transceiver Station (BTS), CTS Fixed Part (CTS-FP) and Mobile Station (MS). These are up to the manufacturer to specify.

Release independent Downlink Advanced Receiver Performance (DARP) - Implementation guidelines |
The present document specifies requirements on MSs supporting Downlink Advanced Receiver Performance (DARP) that are independent of release. TSG GERAN has agreed that the standardisation of DARP be independent of a release. However, in order to implement an MS that conforms to a particular release but supports DARP, which is specified in a later release, it is necessary to specify some extra requirements.
DARP - phase II is contained in the Release 7 specifications. In order to implement an MS conforming to Release 5 but supporting DARP - phase II, it is necessary for the MS to additionally conform to some parts of the Release 7 specifications, such as the radio frequency requirements for DARP and some signalling extensions relating to the MS Classmark and radio access capabilities.

Feasibility study on Single Antenna Interference Cancellation (SAIC) for GSM networks |
The objective of this document, as defined in the work item, is to determine the potential of SAIC in typical network layouts. This includes study of the following aspects:
|
| a) |
Determine the feasibility of SAIC for GMSK and 8PSK scenarios under realistic synchronized and non-synchronized network conditions. Using a single Feasibility Study, both GMSK and 8PSK scenarios will be evaluated individually.
| |
| b) |
Realistic interference statistics including CIR (Carrier to Interference plus noise Ratio) and DIR (Dominant-to-rest of Interference Ratio) levels and distributions based on network simulations and measurements, where possible.
| |
| c) |
Robustness against different training sequences.
| |
| d) |
Determine method to detect/indicate SAIC capability.

Circuit switched voice capacity evolution for GSM/EDGE Radio Access Network (GERAN) |
The present document is an output of the 3GPP study item "Multi-User Reusing-One-Slot" (MUROS).
It contains a section describing the objectives of the Circuit Switched Voice Capacity Evolution, and further sections presenting candidate techniques, which are evaluated according to their potential related to voice capacity improvement in GERAN. For this the design of a new set of training sequences with improved cross correlation properties to the existing set of training sequences is foreseen and expected to be evaluated. The study will also include the investigation of different optimised pulse shapes for MUROS for both the uplink and the downlink.
