There is already a command line option called 'ue-scan-carrier' which
seemed to blindly look for SSB by changing the center frequency by
+/-100Hz if the previous attempt failed. This is probably copied from
LTE and is not suitable for NR. This commit uses this option to either
1. Perform initial sync on one GSCN if the SSB position if known
2. Or scan the all GSCN (if the SSB postion is unknown)
Also, the following is done for re-synchronization
1. Scan all GSCN when UE comes back from IDLE state
2. Scan one GSCN when UE does re-estabishment
Removed dependency of lte-softmodem.h in nr-softmodem.c.
CONFIG_HLP_UESCAN is declared also in lte-softmodem.h.
- Phy configuration will be prepared by MAC
- Sidelink preconfiguration parameters passed from RRC->MAC
- Only 1 SSB TA allocation used
- psbch payload prepared by MAC after receiving the tx slss req
The UL_INFO_mutex is used in only one place, and therefore useless.
Also, the scheduler uses a lock internally to prevent concurrent access.
Hence, the UL_INFO_mutex is not needed.
Remove kill_gNB_proc(), as it is now dead code.
SCF FAPI 222.10.02 had a bug on the description of CoreSetType:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of CRB0 for DMRS mapping)
1: otherwise (subcarrier 0 of CORESET)
That was fixed in SCF 222.10.04:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of the CORESET)
1: otherwise (subcarrier 0 of CRB0 for DMRS mapping)
That wrong description created a misunderstanding, to overcome it we "wrongly" added a third value. This commit fixes that and aligns the CoreSetType with FAPI 222.10.04
remove several unused files
remove mem_block_t that is never used in a different way than a simple heap buffer
move up IP address type and remove duplications of the same struct declaration
PDU Length is as per SCF 222.10.02: The total length (in bytes) of the
PDU description and PDU data, without the padding bytes. From
TX_DATA.request we get 8 (2 bytes PDU_Length + 2 bytes PDU_Index + 4
bytes num_TLV ) and from each TLV we get 4 + value size ( 2 bytes tag +
2 bytes length + value size without pading)
Therefore, add function to compute PDU_length() value for
TX_Data.request, taking into account how many TLVs there are.
compute_PDU_length() does not rely on access to `nfapi_nr_pdu_t`.
Put it into nr_mac_common.c to avoid introducing dependencies.
