Francisco Paisana a865858db3 disable srbs UL during handover to avoid UL grants and scheduling requests before the handover is complete 2020-10-30 21:51:58 +00:00
Andre Puschmann f647343f18 rlc_am: fix poll bit during header reconstruction 
this makes sure that the reconstructed RLC AM header
has the poll bit set when any of its segments had it set.

this triggered a bug in RLC AM because the Status PDU
isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.

author tested with local 4 port cell. I am not able to verify locally but
it looks ok, we'll revise later if needed.

gracid f67a152a2a Remove unnecessary Lime calibration step from Soapy implementation 
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.

Andre Puschmann 5e7de0a95b cmake: install individual libraries (common, phy, etc) 
this seems to be important for package maintainers
or people who use srslte components in other projects
thar require to link against static libs

so besides installing headers, the apps and the RF lib, we also
install all individual libraries

this fixes https://github.com/srsLTE/srsLTE/issues/500#
and https://github.com/softwareradiosystems/srsLTE/issues/1754

Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function 
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.
