name: WG
full_form: Working Group
context: requirements on a permissible 3GPP TMA out-band gain mask in order for a TMA+BS chain to still meet the TS 25.104 requirements at test port B (this is related to the possible generation of IMD within the BS in presence of overgain on out-band interferers). Furthermore, 3GPP TMA IMD requirements need to be based on a specific assumptions on the out-band gain mask, see separate section 2.1. - NF (one constraint is that the TMA+BS chain has to meet the TS 25.104 reference sensitivity requirement at test port B) - NF variation - Over operating temperature - EVM on RX path (due to filter GDD). This is related to the TS 25.104 demodulation performance requirement at test port B. The total permissible EVM of the TMA + BS RF chain needs to be established and then be divided between 3GPP TMA and BS. This division (and hence the TMA requirement) may depend on the operating band. - RX path time delay (related to UTRAN measurements in TS 25.215) - 1 dB compression - RX IL - Bypass mode - Passive
description: The Working Group (WG) is a subgroup within the 3GPP organization, specifically TSG SA WG 5, responsible for defining parameters and functionality across the Itf-N interface needed for network-wide controlling of RET antenna devices. This group plays a crucial role in standardizing the control of Remote Electrical Tilting (RET) antennas in UTRAN networks.
explanation: The context explicitly mentions 'TSG SA WG 5' as an entity that should provide parameters and functionality across the Itf-N interface, indicating its role in defining standards for controlling RET antenna devices. This points to the Working Group being part of the organizational structure of 3GPP, involved in specific tasks related to standardization.
