Notation

Definition

C all

The set of all downlink connections

L

The number of all downlink connections, i.e., L=|Call|

C i

The i th connection after the flow scheduling phase

W i

The requested bandwidth for C i , in terms of bytes

A i

The number of allocated slots for C i in the flow scheduling phase

M

The number of subchannels in a downlink subframe

N

The number of slots within one subchannel

R

The MCS matrix for different connections on different subchannels, where R(i,j) specifies the MCS used by C i on the j th subchannel

B i

The constructed downlink burst for C i

NOS i

The number of occupied slots by B i

MCS i

The MCS adopted by B i

Th i

Throughput achieved by C i
