Active Antenna System (AAS) Base Station (BS) transmission and reception
The present document establishes 2 sets of minimum requirements and minimum performance requirements; hybrid requirements set which specify requirements for a hybrid AAS BS with both a conducted and a radiated interface and OTA requirements set which specify requirements for an OTA AAS BS which has a radiated interface only.
The hybrid AAS BS requirements are specified for E-UTRA AAS Base Station (BS), the FDD mode of UTRA AAS Base Station (BS), the 1,28 Mcps TDD mode of UTRA AAS Base Station (BS) in single RAT and any MSR AAS Base Station (BS) implementation of these RATs (including NR BS type 1-H MSR configurations).
The OTA AAS BS requirements are specified for E-UTRA AAS Base Station (BS), the FDD mode of UTRA AAS Base Station (BS), in single RAT and any MSR AAS Base Station (BS) implementation of these RATs (including NR BS type 1-O MSR configurations).
NOTE 1: The present document does not establish minimum RF characteristics or minimum performance requirements for Narrow-Band Internet of Things (NB-IoT) in band, NB-IoT guard band, or standalone NB-IoT operation, for AAS BS in single RAT E-UTRA operation or in MSR operation using E-UTRA.
NOTE 2: The present document does not establish minimum RF characteristics for MBMS for AAS BS in single RAT E-UTRA operation.
