B.6 Birth-Death propagation conditions

25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)

The dynamic propagation conditions for the test of the baseband performance is a non fading propagation channel with two taps. The moving propagation condition has two taps, Path1 and Path2 while alternate between ‘birth’ and ‘death’. The positions the paths appear are randomly selected with an equal probability rate and are shown in figure B.4.

Figure B.4: Birth death propagation sequence

NOTE1: Two paths, Path1 and Path2 are randomly selected from the group [‑3, ‑2, ‑1, 0, 1, 2, 3] chip(781.25ns). The paths have equal strengths and equal phases.

NOTE 2: After 191 ms, Path1 vanishes and reappears immediately at a new location randomly selected from the group [‑3, ‑2, ‑1, 0, 1, 2, 3]chip but excludes the point Path2.

NOTE 3: After additional 191 ms, Path2 vanishes and reappears immediately at a new location randomly selected from the group [‑3, ‑2, ‑1, 0, 1, 2, 3] chip but excludes the point Path1.

NOTE 4: The sequence in 2) and 3) is repeated.
