SRS feedback for 1 layer

Roberto Louro Magueta requested to merge develop-SRS-feedback into develop
  • Fix DCI 0_1 size (COTS UE couldn't decode DCI 0_1 when SRS was configured with 2 ports, but now we have success);
  • Get values to SRS resource indicator to DCI 0_1 (in develop, it is always 0);
  • Get values to precoding information to DCI 0_1 (in develop, the TPMI of DCI 0_1 is always 0);
  • Configuration of number of SRS ports based on UE capability;
  • TPMI computation up 4 antenna ports and 1 layers (tested up to 2 antenna ports with COTS UE, where the TPMI varies as we move the UE, and remain constant when the UE is in the same position).

As a future work, when gNB is able to work with 2 layers, the UL-RI should be calculated, as well as TPMI for 2 layers.
