Figure 8.143-1: PC5 QoS Flow

If the Range flag, in bit 1 of octet 5, is set to "1", then the Range field shall be present in octet 15, otherwise the octet 15 shall not be present.

Octet 6 contains the "5QI" value, as specified in 3GPP TS 23.501 [82].

The Guaranteed Flow Bit Rate and Maximum Flow Bit Rate fields are encoded as kilobits per second (1 kbps = 1000 bps) in binary value. The Guaranteed Flow Bit Rate and Maximum Flow Bit Rate fields may require converting values in bits per second to kilobits per second when the Guaranteed Flow Bit Rate and Maximum Flow Bit Rate values are received from an interface other than GTPv2 interface. If such conversions result in fractions, then the value of Guaranteed Flow Bit Rate and Maximum Flow Bit Rate fields shall be rounded upwards. For non-GBR PC5 QoS flows, both the Guaranteed Flow Bit Rate and Maximum Flow Bit Rate should be set to zero.

The Range field is in the unit of meters, and only used for groupcast communication, as specified in 3GPP TS 36.413 [10]. Range field is encoded as a one octet long enumeration.

NOTE: 3GPP TS 36.413 [10] specifies several enumeration values, i.e. 0 (indicates "m50"), 1 (indicates "m80") and etc.
