Table 1 Notations for scheduling metrics

m _i,k

Common metric for the i ^th user’s k ^th resource block

\( {d}_k^i(t) \)

The attained data rate by the i ^th user at the t ^th period

\( {\overline{R}}^i(t) \)

The i ^th user’s attained regular amount of throughput until time t

D _HOL,i

The head-of-line delay of the i ^th packet

τ _i

The threshold delay of the i ^th user

w _i,k

The channel’s weighted spectral efficiency for the i ^th user in the k ^th resource block

δ _i

The reasonable amount of packet loss by the i ^th user

N _RT

Number of real-time traffic flow
