Position of SSB from Point A depends on offsetToPointA and Kssb, and for both, the unit for RB is expressed as 15KHz for FR1 and 60 KHz for FR2, so scaling must be 4 for FR2 frequencies
The macrlc_has_f1 (static) variable was introduced to signal when we use
F1 in the configuration. It is superfluous: the node_type already passes
this information in a unique manner; hence, remove.
Correctly match UEs based on the NSSAI in MAC and RRC. There is a
convenience function capture_sst_sd() that extracts SST and SD (which
form the NSSAI). Because a previous version used integers to convey the
slice identifier, this function gracefully handles this case, although
it is not spec-compliant.
Prior to this commit, the RAN function for KPM is leaking memory: it
allocates using calloc() but never frees it.
The fix consists of not allocating this memory on the heap in the first
place, but on the stack. Therefore, there are changes to pass in a
pointer to various functions to the structure on the stack, instead of
passing the "container" for the heap memory by value.
Further, the MAC was allocating an excessive amount of memory (N times
sizeof(NR_UE_info_t)). Instead of copying the entire struct, the present
code stores a pointer to the MAC UE container (NR_UE_info_t *). For the
RRC, there is a similar simplification that consists in not storing the
entire struct f1_ue_data_t (which is not required), but only the RRC UE
ID.
Note that both MAC and RRC might suffer from race conditions. For the
MAC, we should lock the scheduler for the time we read statistics. For
the RRC, the problem is more delicate as no mutex exists; the RRC
assumes everything is executed synchronously in the ITTI task loop. In
both cases, this commit does not address this problem
Filtering UEs by NSSAI is broken, so remove it. A later commit will
reestablish this functionality.
Simplify the code: we only handle one condition, so we can check for it
upfront.
This commit introduces an additional (implicit) option that signals if
the E2 agent is to be activated or not. When reading the configuration,
we now check if all fields are set, and activate the E2 agent only if
this is the case. If not, we only print a warning and start the gNB
without the agent.
Note that previously, if not all fields are set correctly, the gNB
stopped.
To implement this behavior, it is necessary to change the defaults of
the RIC IP and the directory for SMs to a (non-NULL) default value.
Otherwise, the configuration system would not consider the field to be
set to the default, and wrongly assumes the field is set, even though it
is not; at least, this change is necessary to make config_isparamset()
return NULL if the configuration is not set.
3GPP has the concept of a gNB-CU-UP ID and a (separate) gNB ID (for gNB,
CU-CP). This commit introduces the gNB-CU-UP as a separate ID that has to be
set in the configuration file when running as a CU-UP. For the
CU/monolithic gNB, it is optional (but needs to be the same as the
gNB-ID if specified).
The CU-UP ID is necessary, as some entities, e.g., the e2 agent, need to
signal both IDs, e.g., to reconcile a CU-CP and (multiple) CU-UP(s)
belonging together.
3GPP has the concept of a gNB-DU ID and a (separate) gNB ID (for gNB,
CU). This commit introduces the gNB-DU as a separate ID that has to be
set in the configuration file. It is necessary, as some entities, e.g.,
the e2 agent, need to signal both IDs, e.g., to reconcile a CU and
(multiple) DU(s) belonging together.
