Since the parent commit, the ra_ResponseWindow will be chosen
automatically. Correspondingly, remove most ra_ResponseWindow options
from configuration files in the repository.
One problem in some mu=1 configs is that the ra_ResponseWindow=4 (10
slots), which might be overly restrictive if the L1 slot ahead is
somewhat close to 10 (e.g., 6), in which case we might not be always
able to allocate Msg2 in time.
A notable exception here is gnb-vnf.sa.band66.u0.25prb.nfapi.conf, in
which we still provide it (1) since it uses a non-standard configuration
of a ra_ResponseWindow longer than 10ms (see also issue #916 for more
information) and (2) as an example.
1. Closes#884 - increase the XRAN_MAX_FRAGMENT from 4 to 6 (sufficient for MTU 1500 with compression 8b)
2. Add new firmware version that supports jumbo frames
3. Update the config file to align with the new Liteon unit in our lab - center frequency, jumbo frames, compression and RU MAC address,
as well as the max DL MIMO layers.
The original UL max MCS of 9 was chosen for performance reasons. In the
meantime, machines became faster, and the ULSCH decoding faster. Improve
UL max MCS to be 28 by default to use the complete range of possible
MCS.
Doing only 5 LDPC iterations by default leads to a poor reception
performance, and correspondingly many retransmissions. Increase to 8 as
the new default to improve user experience.
system_core is the core reserved for DPDK control threads. It was
hardcoded to 0, but it seems that one some systems, CPU 0 cannot be
reasonably isolated from kernel threads. Make it therefore configurable
(default: 0)
Closes: #732 (suggestion 1)
Suggested-by: Andrew Sergeev <andrew.sergeev@adtran.com>
- Add the O-RAN 7.2 FHI library, interfacing with OSC xRAN library (E
release)
- Add Findxran.cmake to detect the library and headers, including
version information
- Test for numa and DPDK presence
- Add patch for OSC xRAN to make interworking possible
- Add sample config files for LiteOn, Benetel, and VVDN units.
Documentation is provided in the next commit.
