NG Toolset开发笔记--5GNR Resource Grid（54）

5/3 update:

aotCsiRs is ok, including:

*transmission of periodic NZP-CSI-RS

*transmission of periodic CSI-IM

*transmission of periodic Tracking-RS(or TRS)

5/5 update:

*TRS periodicity should be slots40.

 

7/28 update:

*bugfix for NZP-CSI-RS row determination (thanks to @gmg2719)

add 'row' and 'bit string' to UI, rational is specified in 38.331--frequencyDomainAllocation IE:

frequencyDomainAllocation

Frequency domain allocation within a physical resource block in accordance with TS 38.211 [16], clause 7.4.1.5.3. The applicable row number in table 7.4.1.5.3-1 is determined by the frequencyDomainAllocation for rows 1, 2 and 4, and for other rows by matching the values in the column Ports, Density and CDMtype in table 7.4.1.5.3-1 with the values of nrofPorts, cdm-Type and density below and, when more than one row has the 3 values matching, by selecting the row where the column (k bar, l bar) in table 7.4.1.5.3-1 has indexes for k ranging from 0 to 2*n-1 where n is the number of bits set to 1 in frequencyDomainAllocation.

and now debug log will include validateNzpCsiRs status:

part of debug output for NZP-CSI-RS row selection:

(1) aotCsiRs is added to alwaysOnTr:

if self.msg4Recved:
            if not self.error:
                self.aotCsirs(hsfn, sfn, slot)

            if not self.error:
                self.aotSrs(hsfn, sfn, slot)

(2) Transmission of NZP-CSI-RS and TRS

TRS is kind of nzp-csi-rs except that TRS always uses: single port with no CDM and density=3 and periodic TRS doesn't need CSI report.

Procedure to determine :

#refer to 3GPP 38.211 vf40
            #Table 7.4.1.5.3-1: CSI-RS locations within a slot.
            #determine ki (k0, k1 etc)
            ki = []
            pos = -1
            while True:
                try:
                    pos = self.nrNzpCsiRsFreqAlloc[::-
