Question: In accordance with 3GPP specifications for Event V1 (channel busy ratio above a threshold) in E-UTRA, how are the variables `Ms`, `Hys`, and `Thresh` expressed for the entering and leaving conditions of this event?
Option 1: `Ms` in percentage, `Hys` in dB, and `Thresh` as a binary value (0/1)
Option 2: `Ms` and `Hys` in decimal (0 to 1), but `Thresh` is always a fixed value of 0.5
Option 3: All three (`Ms`, `Hys`, `Thresh`) are expressed in dBm, with `Ms` requiring conversion from its measured unit
Option 4: `Ms`, `Hys`, and `Thresh` are all expressed in decimal (from 0 to 1) in steps of 0.01 for `Ms`
Explanation: According to the specifications, for Event V1, `Ms` (measurement result of channel busy ratio), `Hys` (hysteresis parameter), and `Thresh` (threshold parameter) are all defined in the same unit, which is decimal from 0 to 1, with `Ms` specifically mentioned as being in steps of 0.01. This uniformity in expression ensures consistency in evaluating the entering and leaving conditions for this event, facilitating accurate assessment of channel busy ratios in E-UTRA networks.
