9 Tracking Reference Signal
38.3043GPPNRRelease 17TSUser Equipment (UE) procedures in idle mode and in RRC Inactive state
The UE in RRC_IDLE and RRC_INACTIVE states may use Tracking Reference Signal (TRS) whose configurations are provided in system information for its paging reception to save power. In a cell in which TRS are available for the UE in RRC_IDLE and RRC_INACTIVE states to use, the availability of the configured TRS is informed to the UEs in RRC_IDLE and RRC_INACTIVE states based on explicit L1 based availability indication defined in TS 38.213 [4].
Annex A (informative):
Example of Hashed ID Calculation using 32-bit FCS
Inputs:
– Least significant bits of 5G-S-TMSI: 0x12341234
– Generator polynomial: 0x104C11DB7 (1 0000 0100 1100 0001 0001 1101 1011 0111)
Procedure to Calculate Hashed ID:
step a)
– k = 32
– numerator: 0xFFFF FFFF 0000 0000
– denominator: 0x1 04C1 1DB7
– remainder Y1 = 0xC704DD7B
step b)
– numerator: 0x1234 1234 0000 0000
– denominator: 0x1 04C1 1DB7
– remainder Y2 = 0x1D66F1A6
Hashed_ID = FCS = ones complement of (remainder Y1 XOR remainder Y2)
= ones complement of (0xC704DD7B XOR 0x1D66F1A6)
= negation of (0xDA622CDD)
= 0x259DD322
