UE positioning in UTRAN - Stage 2 |
This TS
specifies the stage 2 of the UE Positioning function of UTRAN, which provides the mechanisms to support the calculation of the geographical position of a UE. UE position knowledge can be used for example in support of Radio Resource Management functions, location-based services for operators, subscribers and third party service providers. The purpose of this stage 2 specification is to define the UTRAN UE Positioning architecture, functional entities and operations to support positioning methods. This description is confined to the UTRAN Access Stratum. It does not define nor describe how the results of the UE position calculation can be utilised in the Core Network (e.g. LCS) or in UTRAN (e.g. RRM).
UE Positioning may be considered as a network provided enabling technology consisting of standardised service capabilities, which enable the provision of location applications. The application(s) may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this technology are outside the scope of the present document. However, clarifying examples of how the functionality being described may be used to provide specific location services may be included.
This stage 2 specification covers the UTRAN positioning methods, state descriptions, and message flows to support UE Positioning.

High Speed Downlink Packet Access (HSDPA) -
Overall description - Stage 2 |
High Speed Downlink Packet Access is based on techniques such as adaptive modulation and hybrid ARQ to achieve high throughput, reduce delay and achieve high peak rates.
It relies on a new type of transport channel, the HS-DSCH, which is terminated in the Node B. HS-DSCH is applicable only to PS domain RABs.
In FDD, the HS-DSCH reception is also supported in CELL_FACH, CELL_PCH and URA_PCH state.
This TS is related to
the overall support of High Speed Downlink Packet Access in UTRA.

Enhanced Uplink - Overall Description - Stage 2 |
The technical purpose of the Enhanced Uplink feature is to improve the performance of uplink dedicated transport channels, i.e. to increase capacity and throughput and reduce delay. This is applicable for UTRA TDD and FDD.
The following techniques are part of the Enhanced Uplink feature:
|
| - |
Node B controlled scheduling: possibility for the Node B to control, within the limits set by the RNC, the set of TFCs from which the UE may choose a suitable TFC.
| |
| - |
Node B controlled physical resource scheduling (TDD only).
| |
| - |
Hybrid ARQ: rapid retransmissions of erroneously received data packets between UE and Node B.
| |
| - |
Higher order modulation (16QAM) (TDD and FDD).
| |
| - |
Intra-frame code hopping (3.84 Mcps and 7.68 Mcps TDD only).
| |
| - |
Shorter TTI: possibility of introducing a 2 ms TTI (FDD only).
|
This TS is related to
the overall support of FDD, TDD Enhanced Uplink in UTRA.

Introduction of the Multimedia Broadcast Multicast Service (MBMS) in the RAN - Stage 2 |
The Introduction of the Multimedia Broadcast Multicast Service in UTRA describes techniques for optimised transmission of MBMS bearer service in UTRA such as point-to-multipoint transmission, selective combining and transmission mode selection between point-to-multipoint and point-to-point bearer.
The Stage 1 MBMS service requirements are defined in 3GPP TS 22.146 and MBMS Stage 1 user services are defined in 3GPP TS 22.246. UTRAN (and GERAN) requirements are covered in 3GPP TR 25.992. The overall architecture, functional description and the reference architecture of MBMS are covered in 3GPP TS 23.246.
This TS relates to the overall support of Multimedia Broadcast Multicast Service in UTRA.
