context: This clause identifies the impact on RRM requirements when standardizing external low noise Tower Mounted Amplifier (TMA) in Rx for UTRA FDD. If a BS is equipped with TMA, the reference point for UTRAN measurements with reference point at âantenna connectorâ shall be the antenna connector of the TMA. This is already the case for BS equipped with a TMA provided by the BS manufacturer and shall also apply to BS with TMA analyzed in the present TR. UTRAN measurements performed in the BS are impacted by the gain and delay in the RX path of the TMA and insertion loss and delay in the TX path of the TMA. The feeder loss between BS and TMA also need to be considered. Therefore, the BS needs knowledge of the following system parameters in order to adjust their measurements with respect to the reference point at the TMA antenna connector: - TMA gain in each RX path - TMA delay in each RX path - TMA loss in each TX path - TMA delay in each TX path - Feeder loss and delay between BS and TMA (for
description: The Wideband Distribution System (WDS) is a network function that enables the radio interface of multiple base stations (BS) to be remote, supporting a distributed multi-carrier and multi-operator network. It includes active devices such as RF front-end and transmission interfaces, as well as ancillary functions for system integration and O&M facilities for supervision requirements.
explanation: WDS is classified as a Network Function because it performs a specific task within a telecommunications network: enabling remote radio interfaces for multiple base stations. This distributed functionality, along with the mention of components like RF front-end and transmission interfaces, aligns with the definition of a Network Function.
