- MAX HARQ PROCESSES set to 32
- for PDSCH - default setting in OAI is 16, according to 3GPP rel17 38.331 these are the possible configs
- if no IES are defined then 8
- if nrofHARQ-ProcessesForPDSCH is defined then these values- {n2, n4, n6, n10, n12, n16}
- if nrofHARQ-ProcessesForPDSCH-v1700 is defined then 32
- for harq bits in DCI
- DCI 1_0 - 4 bits spec 38.212, section 7.3.1.2.1
- DCI 1_1 - 4/5 bits according to IE harq-ProcessNumberSizeDCI-1-1, spec 38.212, section 7.3.1.2.2
- for PUSCH - default setting in OAI is 16, according to 3GPP rel17 38.331 these are possible configs
- if no IES are defined then 16
- if nrofHARQ-ProcessesForPUSCH-v1700 is defined then 32
- for harq bits in DCI
- DCI 0_0 - 4 bits spec 38.212, section 7.3.1.1.1
- DCI 0_1 - 4/5 bits according to IE harq-ProcessNumberSizeDCI-0-1, spec 38.212, section 7.3.1.1.2
- FOR HARQ32 , DCI 1_1, DCI 0_1 should be configured in UE dedicated search space. In OAI it is set.
This assert and assumption is incorrect, according to 38.101-1 UE channel is defined only by the BWP size
and BWP size can be any value supported by the RRC parameters defining the BWP.
To determine the UE channel the smallest bandwidth supporting the BWP is selected. This is an assumption based
on references in the same document to UE channel bandwidth being equal to one of the values in set
{5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100}.
Also:
- calculated P_CMIN during BWP setup since the parameter doesn't depend on DCI.
- initiialize uniqCfg structure in test_nr_ue_power_procedures main function which enables LOG prints during tests
Till this commit, the UE gets the position of SSB in frequency from
command line and does the syncronization by locating the SSB in time. It
does this by generating a PSS time signal during initialization with the
SSB offset given via command line. Then PSS detection is done by
correlation.
In this commit, the UE computes a list of GSCN in the current NR band
that falls within the current bandwidth for the set center frequency.
For each GSCN in the list, the UE starts a thread and performs the
following:
1. Generate PSS time signal with SSB offset for current GSCN.
2. Detect PSS, SSS and decode PBCH (this step remains the same).
After all threads finishes, the results are collected.
For now, only the first detected PBCH is used to proceed further. So
this PBCH is indicated to MAC and UE exits initial sync.
Future work: The cell search can be standalone feature where the UE
could scan for SSB in the entire NR band. This would require changing
radio's frequency on the fly as the UE's bandwidth would not cover an
entire NR band. The cell detection can futher be imporved by looking
for SIB1 for each decoded PBCH.
- Implement: Extend the F1 encoding and decoding with Qos
- Implement: E1 decoding for QoS
- Fix: Modify the UE_MODIFICATION_REQUEST_MSG towards DU to contain QoS info based on E1AP context response
- Fix: Modify the E1AP and F1AP message structures
- Fill the Qos configuration to send to MAC
