In the configuration file, to enable measurements, add:
enable_measurement_reports = "yes";
Note that if x2 is enabled then the option 'enable_measurement_reports'
is not taken into account and the measurements are enabled.
* Instead of partly initializing in read_config_and_init(), everything of
PDCP is initialized in main() of lte-softmodem
* Omit RC.rrc access in RRU through checking of RC.nb_inst > 0
* Includes FlexRAN, i.e. do not start FlexRAN in RRU
* Function pointers to PDCP functions have to be set explicitly (avoid
confusion of multiply setting function pointers)
-- rrc_inactivity_threshold in seconds
Adding support in CI to test it
-- disable/enable data service on UEs
-- no automatic check yet on the UE status
certainly should be done w/ a Flexran controller command

end_of_burst_delay is used to stop TX only "after a while".
If we stop right after effective signal, with USRP B210 and
B200mini, we observe a high EVM on the S subframe (on the
PSS).
A value of 400 (for 30.72MHz) solves this issue. This is
the default.
This default value can be changed in the configuration file.
For example:
RUs = (
{
local_rf = "yes"
nb_tx = 1
nb_rx = 1
att_tx = 20
att_rx = 0;
bands = [7];
max_pdschReferenceSignalPower = -27;
max_rxgain = 105;
eNB_instances = [0];
sf_extension = 312;
end_of_burst_delay = 200;
}
);
Here we would set a value of 200.
The value to put in the configuration file is for
30.72MHz. The value is scaled accordingly at runtime
(thus only one value to set for every RB configuration,
25, 50 or 100, leading to less problems when adapting
configuration files).
This option is for experts and should not be changed
randomly.
This parameter is meaningful in TDD, to decide
when to start DL at eNB side. Since there is a
need for the PA to be operational, we need to
transmit a bit before the DL subframe coming
after an UL subframe. (We transmit zeros.)
We used to use N_TA_offset which may be too much.
Default value is now N_TA_offset/2 and can be
changed in the configuration file, in the RUs
section, like:
RUs = (
{
local_rf = "yes"
nb_tx = 1
nb_rx = 1
att_tx = 0
att_rx = 0;
bands = [7];
max_pdschReferenceSignalPower = -27;
max_rxgain = 105;
eNB_instances = [0];
sf_extension = 312;
}
);
N_TA_offset is 624 (for 30.72MHz). In the example
above, we set sf_extension = 312, which is also
the default.
The value to put in the configuration file is for
30.72MHz. The value is scaled accordingly at runtime
(thus only one value to set for every RB configuration,
25, 50 or 100, leading to less problems when adapting
configuration files).
This option is for experts and should not be changed
randomly.
This commit introduces X2AP timers (t_reloc_prep, tx2_reloc_overall).
You need to set the values in the configuration file.
X2AP can be enabled or disabled in the configuration file too (disabled
by default).
Some deadcode was removed.
- free correctly in rrc_eNB_free_mem_UE_context
- check for existence of ue_context.handover_info in rrc_enb_process_itti_msg
- check return value sctp_peeloff in sctp_handle_new_association_req_multi
and exit in case of failure
--> openair2/LAYER2/MAC/eNB_scheduler_primitives.c is still old (not from issue394_fix_cppcheck branch)
