Do we have a better method, capable to inspect each RB?

Question

As we know Per Resource Blocks (RB) SINR from UE report. I know that an UE reports all the RBs SINR as quick as possible (maybe each subframe period, that is 1 ms). I’m thinking of the Higher Layer-configured subband CQI report since it’s the most capable of inspecting the RBs status as I saw in 3GPP 36.213 Table 7.2.1-1. I’m interested in FDD; unfortunately the least “RB contiguous number” is 4 as in Table 7.2.1-3. Do we have a better method capable to inspect each RB?

Answer 1

The least RB contiguous number is defined in this table that you mentioned 7.2.1-1 of 36.213. From the standard point of view that’s the only possibility (meaning the lowest granularity possible). This is due to the tradeoff that the standard needed to take between the accuracy (high granularity of the reports) and feedback overhead (low granularity of the reports). While designing a practical system, you need to take into account these tradeoffs
