How LTE TDD base station downlink transmit off power affects quality?The quality of the LTE TDD base station downlink transmit Off power not only has a direct impact on the uplink communications quality but since there is also a risk of impact on connected systems, sometimes different regions and service operators set stricter standards than the 3GPP specifications.
Why is LTE TDD transmit on/off power measurement difficult?The reason why LTE TDD transmit On/Off power measurement is difficult is because both a high power at transmit On and a low power at transmit Off must be input continuously to the signal analyzer.
How to set Foff for LTE?4. Switch on the baseband and set the frequency offset of the wanted LTE carrier in order to set the LTE carrier in the adjacent channel: Foff = BWLTE(example. Fig. 3-45: SMW: offsets in the baseband. Fig. 3-46: Setting the frequency offset for the W-CDMA carrier (example:20.0 MHz). 5.
How many lbbp boards can be configured in a base station?The number of LBBP boards to be configured in a base station that supports LTE depends on the number of cells, bandwidths, antenna configurations, and the number of CPRI ports to be supported by the base station. Each BBU working in LTE mode needs to be configured with at least one LBBP and each LBBP supports six RF modules.
Which ubbp boards support LTE only mode?In eRAN7.0, the following UBBP boards support LTE only mode: UBBPd3, UBBPd4, UBBPd5, and UBBPd6. A UBBPd4 does not support a hybrid configuration of 1R and 4R cells, or 2R and 4R cells. In SRAN9.0 (V100R009C00SPC210) or later, a UBBPd5 supports a hybrid configuration of 1R and 4R cells, or 2R and 4R cells. In a hybrid configuration.
