1. Previous SW configuration for different RRC version relies on whether macro Rel10,
Rel14 defined or not by checking #ifdef Rel14 or #if defined(Rel10) || defined(R14).
Whenever there is a newer RRC version, e.g. Rel15, it will be very a tedious and
error-prone job to add defined(Rel15) in every place.
2. Some RRC messages are defined in release 13 instead of release 14, NB-IoT
feature is one of such example. Our code shall reflect this fact instead of using
an afterward version number in software configuration.
3. Some RRC messages or some fields of certain RRC messages are added in the middle
a release, e.g. SystemInformationBlockType1_v1310_IEs_t defined in RRC 13.1.0
and RRC 9.2.0 made some changes to SIB12 and SIB13 so we have sib12_v920 and
sib13_v920 fields in SIB12 and SIB13's struct.
We need a finer grain of control when using ASN1 from different RRC version.
4. S1AP also has this problem that it use UPDATE_RELEASE_9 and UPDATE_RELEASE_10 to
differentiate between various S1AP version.
This commit propose using MAKE_VERSION(x,y,z) to designate the version number and
modify current conditional compilation accordingly.
Note: 2018/04/16, Modified based on Cedric's comment.
The PHICH was not programmed for the last round (4) because it was
not programmed in rx_sdu but in schedule_ulsch_rnti, only in case
of a programmed retransmission (there is obviously no retransmission
programmed after the last round).
The case of Msg3 is not handled. To be done somehow.
As reported by Emad Alizade:
According to "Issue255 256 257 paging reesta release" that has been
merged in develop version, we have a question: In rrc_eNB_free_UE()
function only all ulsch related memory of user has been cleaned, but
I think not only ulsch memory but also dlsch memory must be cleaned.
I tested the latest develop version and with repetition UE attach-detach
procedures we find that the dlsch memory has not been cleaned and after
repeat this sequence (45 times) assertion with cause UE_id!=-1 (no free
or exiting dlsch_context, dci_tools.c: fill_dci_and_dlsch() ) occurred
and no UE will be attached to system.
The fixes in this commit are from Emad Alizade.
