Section: 5.8.11 Zone identity calculation
Content: The UE shall determine an identity of the zone (i.e. Zone_id) in which it is located using the following formulae, if sl-ZoneConfig is configured: x1= Floor (x / L) Mod 64; y1= Floor (y / L) Mod 64; Zone_id = y1 * 64 + x1. The parameters in the formulae are defined as follows: L is the value of sl-ZoneLength included in sl-ZoneConfig; x is the geodesic distance in longitude between UE's current location and geographical coordinates (0, 0) according to WGS84 model [58] and it is expressed in meters; y is the geodesic distance in latitude between UE's current location and geographical coordinates (0, 0) according to WGS84 model [58] and it is expressed in meters. NOTE: How the calculated zone_id is used is specified in TS 38.321[ NR; Medium Access Control (MAC) protocol specification ]  [3].
