The maximum spreading factor informs what this repetition should be since the header information at the start of the frame needs to be spread by the maximum spreading factor in use in the network in order that all terminals in the cell can decode it.
The SEM measurement is used to measure the excess emissions that would interfere to other channels or to other systems.
The limits are generally based on international regulations In addition, there are base station and UE emission limits defined for the receiver. The spectrum emission mask of the UE applies to frequencies within A key starting point in defining the PHY is the conflict between excellent coverage requirements and yet low-power constraints due to both white space regulation and the need for long battery life in terminals. Outside of the frequency range of the mask, the spurious emissions limits apply. For an active system such as NR, the EIRP may vary considerably between the desired signal and the unwanted emissions and also between implementations, thus EIRP (in this case) is not proportional to TRP and should not substitute TRP The device output power level is set by taking the following considerations into account The minimum output power level configuration defines the device dynamic range. Specifically, the average power spectral density (PSD) cannot exceed −41.3 dBm/MHz over the frequency band from 3.1 to 10.6 GHz, and it must be even lower outside this band, depending on the specific application A common technique to implement UWB systems is called Indeed the potentials of UWB systems triggered the formation of the IEEE 802.15 low rate alternative PHY task group (TG4a) in 2004 with the objective of providing an amendment to IEEE 802.15.4 According to the IEEE 802.15.4a specification, the packet structure shown in We use cookies to help provide and enhance our service and tailor content and ads. Thus, the conversions between the frequency-coded values and their real values areFor the UTRA base station, the mask extends out to the transmitter operating band edge, or 12.5 MHz from the carrier, as illustrated in The SEM is defined as a general mask and a set of additional masks that can be applied to reflect different regional requirements. For TDD, where two sounding reference signals can be transmitted on adjacent symbols in the UpPTS field, the transient periods are located between the two sounding reference signals. For implementation purposes, it is not possible to define a generic device spectrum mask that does not vary with the channel bandwidth, thus the frequency ranges for OOB limits and spurious emissions limits do not follow the same principle as for the BS.
Note that although the requirement is given in terms of a mask, it actually applies to the average power during the ON and OFF periods. Terminal spurious emission limits are defined for all frequency ranges outside the frequency range covered by the SEM. The limits are generally based on international regulations In addition, there are BS and terminal emission limits defined for the receiver. In all these cases, the transient periods are symmetric around ACLR is the ratio of the filtered mean power centered on the assigned channel frequency to the filtered mean power centered on an adjacent channel frequency.
