NG Toolset開發筆記--5GNR Resource Grid(35)

截至11/13號完成:

*SSB settings

*PDCCH settings

 

when 'carrier band' is changed:

*update 'groupPresense' in SSB settings

 

when 'carrier scs' is changed:

*update 'scsCommon' in MIB and 'refScs' in TDD-UL-DL-Config-Common

Note: for simplicity, assume scsCommon and refScs equals to scsCarrier.

 

when 'controlResourceSetZero' is changed:

*validate its value

*validate coreset0 bw against carrier bw

*further validate coreset0/ssb against carrier bw if k_ssb is configured

 

Considerations on CORESET0/SSB and Carrier BW:

*here, offset is from 38.213 Table 13-1~Table 13-10

*basic assumptions: If offset>0, then 1st RB of CORESET0 aligns with the carrier edge; if offset<=0, then 1st RB of SSB aligns with the carrier edge.

*please refer to the figure below if you are confused:

 

Further considerations on PDCCH/DCI, CORESET/SearchSpace, PDSCH/PUSCH settings:

*DCIs may be placed in 'PDCCH settings' tab

*need 'BWP tab' to cover: initial ul bwp(as defined in SIB1), initial dl bwp(as defined in SIB1), dedicated ul bwp and dedicated dl bwp. only bwp specific parameters will be included

*need 'initial access tab' to cover: msg1(aka PRACH), msg2(which contains ul grant for msg3), msg3 by rar ul grant, msg4 and its feedback by pucch(as specified in sib1)

*need 'pucch tab' to cover pucch settings(excluding the common pucch configurations from sib1)

*need 'normal pusch tab' to cover normal pusch transmission, including srs, dmrs and possible ul ptrs

*need 'normal pdsch tab' to cover normal pdsch transmissoin, including dmrs and possible dl ptrs, and possible CSI-RS which will be included later.
