name: REFSENS
full_form: Reference Sensitivity
context: The frequency bands grouping for FR2 presented in Table 3.5.3-1 is derived based on UE REFSENS requirements and assuming 0.5 dB step between the neighbour groups. The groups are defined in the order of increasing REFSENS, i.e., the group A has the smallest REFSENS among the groups. UE REFSENS for band n259 is defined in TR 38.887 [1] as follows: Table 8.1.2-1: Reference sensitivity In Table 3.5.3-2, Group Y which includes n260 PC3 with REFSENS of -85.7/50 MHz, Table 7.3.2.3-1 in TS 38.101-2 , corresponds to UE REFSENS of -85.5. Since REFSENS for band n259 is -84.7 dBm/50 MHz, we need to introduce two new groups considering the 0.5 dB steps between two groups. The two new groups are presented in Table 3.5.3-1.

description: Reference Sensitivity (REFSENS) is a critical network attribute that defines the minimum signal strength required by a user equipment (UE) to maintain a reliable connection with the base station. It is an essential parameter in determining the coverage and performance of wireless networks, particularly in the context of frequency bands grouping for FR2 as presented in 3GPP TS 38.887.
explanation: The description defines REFSENS as a network attribute that directly impacts the performance and coverage of wireless networks by setting a minimum signal strength requirement for user equipment connection.
