资源块的定义：
LTE中物理资源块的进一步认识_CodeSavior的博客-CSDN博客_资源块
看论文的时候有时候非常困惑，10MHz有50个资源块还是50对资源块
Channel bandwidth of 10 MHz corresponds to 50 pairs of RBs per subframe
论文1：Study of the Impact of PHY and MAC Parameters in 3GPP C-V2V Mode 4
The typical channel bandwidth of10 MHz is assumed, which corresponds to50 pairs of resource blocksper sub-frame. A non-adjacent allocation of SCIs, with four subchannels of 10 pairs (and the remaining used by the SCIs) are assumed.
论文2：Understanding the Impact of the PC5 Resource Grid Design on the
Capacity and Efficiency of LTE-V2X in Vehicular Networks
LTE-V2X supports channel bandwidths of 10 MHz and 20 MHz, which would have 50
RBs per subframeand 100 RBs per subframe, respectively [10].
论文3Optimizing the Resource Allocation of Periodic Messages With Different Sizes in LTE-V2V
In LTE, two slots are grouped into one subframe and the pairs of resource blocks
of one subframe (two slots, same bandwidth) are always allocated together and hereafter denoted as resource block pairs (RBPs). 最可信
论文看了这么多，总算分清楚了资源块与资源块对
36.331
Value n2 corresponds to 2 physical
resource-block pairs; n4 corresponds to 4 physical resource-block pairs and so on
