1 Scope p. 7
The present document establishes over the air antenna minimum requirements for user equipment (UE) and mobile station (MS).
Handheld UE requirements are defined for roaming bands for the speech position (beside the head and beside the head and hand) and hand phantom browsing mode position. Laptop mounted equipment requirements are defined for roaming bands for the data transfer position (laptop ground plane phantom). Laptop embedded equipment requirements are defined for roaming bands for the data transfer position (free space).
All bands are potential roaming bands, and the requirements for roaming bands shall therefore be fulfilled for all bands supported by a UE/MS.
Requirements for operating bands are dependent on how the network has been built and are thus operator specific and cannot be specified here. Recommended performance values for operating bands (Annex B) are however included in this specification for information. It should be recognised that the ability to meet the recommended performance values depends on the number of frequency bands supported by the UE/MS.

3 Definitions, symbols and abbreviations p. 8
3.1 Definitions p. 8
For the purposes of the present document, the terms and definitions given in TR 21.905 , TR 37.977 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 or TR 37.977.
primary mechanical mode:
the mode that is most often used during a call beside the head. Other mechanical modes are secondary. Every terminal has at least one primary mechanical mode.
speech position:
UE used close to head phantom (specific anthropomorphic mannequin).
data transfer position:
UE used away from the user's head, applicable for LME and LEE devices.
FS:
UE used in a free space configuration.
LME:
Laptop mounted equipment (such as plug-in devices like USB dongles).
LEE:
Laptop embedded equipment (such as embedded module card embedded in notebooks).
