NG Toolset开发笔记--5GNR Resource Grid(35)

本文详细介绍了5G无线网络中SSB设置、PDCCH设置等关键参数的配置流程与注意事项,包括载波带宽变更时的SSB组存在状态更新、控制资源集零的验证与调整,以及与载波带宽相关的CORESET0和SSB对齐考虑。此外,还涵盖了PDCCH/DCI、CORESET/搜索空间、PDSCH/PUSCH设置的全面考量。

截至11/13号完成:

*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.

 

sib1 tab
---->pdcch(coreset0/css0) defined in separeted PDCCH tab

initial ul bwp tab
---->prach/msg1
---->pucch sib1
---->rar ul grant for msg3 tx
---->msg3 retransmission, assume no msg3 retx

initial dl bwp tab
---->msg2 tab
---->msg4 tab


dedicated dl bwp tab
---->pdcch(coreset1/uss), defined in separated PDCCH tab
---->normal pdsch

dedicated ul bwp tab
---->pucch
---->normal pusch
---->srs
