3 Definitions and Abbreviations Word‑p. 7

3.1 Definitions |R5|

For the purposes of the present document, the following terms and definitions apply.

cell portion:

A geographical part of a cell for which a Node B measurement can be reported to the RNC. A cell portion is semi-static, and identical for both the UL and the DL. Within a cell, a cell portion is uniquely identified by a cell portion ID.

DL_DCH_FET_Config:

Higher layers signal this configuration parameter to indicate enhanced DCH physical layer configuration. The possible values are 0 and 1. The value 0 indicates Mode 0 configuration where DL transport channels concatenation and UL ACK/NACK signalling are not configured. The value 1 indicates Mode 1 where DL transport channel concatenation and UL ACK/NACK signalling for DL FET are configured.

4 Control of UE/UTRAN measurements

In this chapter the general measurement control concept of the higher layers is briefly described to provide an understanding on how L1 measurements are initiated and controlled by higher layers.

L1 provides with the measurement specifications a toolbox of measurement abilities for the UE and the UTRAN. These measurements can be differentiated in different reported measurement types: intra-frequency, inter-frequency, inter-system, traffic volume, quality and UE internal measurements (see [14]).

In the L1 measurement specifications the measurements, see chapter 5, are distinguished between measurements in the UE (the messages will be described in the RRC Protocol or MAC Protocol [22]) and measurements in the UTRAN (the messages will be described in the NBAP and the Frame Protocol).

To initiate a specific measurement the UTRAN transmits a 'measurement control message' to the UE including a measurement ID and type, a command (setup, modify, release), the measurement objects and quantity, the reporting quantities, criteria (periodical/event-triggered) and mode (acknowledged/unacknowledged), see [14].

When the reporting criteria is fulfilled the UE shall answer with a 'measurement report message' to the UTRAN including the measurement ID and the results.

In idle mode the measurement control message is broadcast in a System Information.

Intra-frequency reporting events, traffic volume reporting events and UE internal measurement reporting events described in [14] define events which trigger the UE to send a report to the UTRAN. This defines a toolbox from which the UTRAN can choose the needed reporting events.
