[srslte-users] srsRAN 21.04 Release Announcement

[Ralph A. Schmid, dk5ras]

Very nice!

On my Intel machine all compile fine, no issues. However the Raspberries feel a bit uneasy with it, this what they spit at me when I'm telling them to build srsRAN:

[ 38%] Built target sequence_test
/home/pi/srsRAN/lib/src/common/liblte_security.cc: In function ‘LIBLTE_ERROR_ENUM liblte_security_milenage_f2345(uint8*, uint8*, uint8*, uint8*, uint8*, uint8*, uint8*)’:
/home/pi/srsRAN/lib/src/common/liblte_security.cc:1158:5: error: ‘mbedtls_aes_crypt_ecb’ was not declared in this scope
     mbedtls_aes_crypt_ecb(&ctx, AES_ENCRYPT, input, temp);
     ^~~~~~~~~~~~~~~~~~~~~
/home/pi/srsRAN/lib/src/common/liblte_security.cc:1158:5: note: suggested alternative: ‘aes_crypt_ecb’
     mbedtls_aes_crypt_ecb(&ctx, AES_ENCRYPT, input, temp);
     ^~~~~~~~~~~~~~~~~~~~~
     aes_crypt_ecb

With best regards

Ralph.

> Dear SDR hackers,
> 
> In case you missed it: srsLTE is now srsRAN!
> Since early 2020, we have been developing support for 5G NR and as we
> expand beyond 4G LTE, our "srsLTE" naming no longer fits like it used to.
> With srsRAN, we will add 5G UE and gNodeB support but we will of course
> continue to develop and improve our existing 4G solutions.
> Indeed, this year sees the first large-scale deployments of our LTE solutions
> in production networks in partnership with our commercial clients. >From the
> very beginning, we have designed and developed our software for real-world
> deployment and this represents a huge milestone for our team and
> community.
> 
> As part of project name change, we’ve updated our repo [1], the project
> website [2] and our documentation [3]. All of your old srsLTE links are
> automatically redirected and will be maintained so no git remote changes
> are required.
> 
> Today we are announcing the very first release: srsRAN 21.04.
> First and foremost, this release includes a FOSS 5G NSA UE implementation
> with an x86-optimized FEC and PHY layer. In other words, one can run a 5G
> NSA UE on commodity compute hardware with _all_ protocol layers
> implemented entirely in software.
> 
> Along with the code release, we’ve provided a dedicated application note [4]
> showing how to setup and test 5G NSA with srsUE.
> 
> Besides the exciting news around srsUE, this new release also brings a
> number of new features for our 4G ENB, including a new scheduler, uplink
> power control, tunnel forwarding over S1 during mobility and PDCP discard
> support to name just a few.
> 
> As usual, many more changes have been made under the hood, including
> optimizations of data structures and memory usage and various other bug-
> fixes and performance improvements throughout the code base. Please
> check the release changelog [5] and git history for more details.
> 
> We'd also like to thank various external contributors, including Supreeth
> Herle, Frederick Pelchat, Nikita Pushchin, Jan Bruckner and Matan Perelman.
> 
> 
> Happy hacking and enjoy the release.
