摘要

This work proposes the two-stage Resource-Minimized Sub-Grouping and Utility-centric (RMSG-U) resource allocation method for Scalable Video Coding (SVC)-based multimedia’s Multicast Broadcast Service (MBS) of Vehicular Users (VUs) over the 5G cellular network. In the 1st stage, RMSG-U selects the minimum number of radio Resource Blocks (RBs) to transmit the corresponding multimedia MBS’s Base Layer (BL). In this way, all VUs in the corresponding multimedia MBS can receive the BL. In the 2nd stage, RMSG-U selects the minimum k RBs that adopt the same Modulation and Coding Scheme (MCS) mcs such that the transmitted data rate of these k RBs is equal to or greater than the multimedia MBS’s corresponding Enhancement Layer’s (EL’s) video data rate to be transmitted. In this way, the considered multimedia MBS’s VUs whose perceived Channel Quality Indicator (CQI) values for these k RBs are all bigger than the CQI value that results in MCS mcs become the subgroup of VUs to receive the corresponding EL. As a result, those VUs of the same subgroup can use the minimum number of RBs to transmit the corresponding EL, which potentially results in more remaining RBs for transmitting more MBSs’ ELs. According to the performance evaluation, the proposed RMSG_U method (i) has the better spectral efficiency and fairness generally and (2) has better average video rate and needs the smaller number of RBs in the situation of VUs having very disperse CQI values comparing with other methods.
