Refactor UL MAC PDU decoding Refactor the UL MAC PDU decoding: A single function is created to decode the entire MAC subheader uint8_t decode_ul_mac_sub_pdu_header(uint8_t *pduP, uint8_t *lcid, uint16_t *length). It returns the length of the MAC subheader and outputs the LCID and Length. This new function is called from 2 functions: lcid_crnti_lookahead() and nr_process_mac_pdu(). After calling it in nr_process_mac_pdu(), the validation of the PDU can be made for all the MAC subPDUs in a single place, allowing for less and more clean code (as opposed with the previous version where the validation was made multiple times inside the LCID switch-case). Additionally, this MR updates the list of LCIDs as in 3GPP TS 38.321 v18.3.0 Table 6.2.1-2: Values of LCID for UL-SCH when the LX field is not present or is set to 0.

How to get support from the OAI Community
You can ask your question on the mailing lists.
Your email should contain below information:
- A clear subject in your email.
- For all the queries there should be [Query] in the subject of the email and for problems there should be [Problem].
- In case of a problem, add a small description.
- Do not share any photos unless you want to share a diagram.
- OAI gNB/DU/CU/CU-CP/CU-UP configuration file in
.confformat only. - Logs of OAI gNB/DU/CU/CU-CP/CU-UP in
.logor.txtformat only. - In case your question is related to performance, include a small description of the machine (Operating System, Kernel version, CPU, RAM and networking card) and diagram of your testing environment.
- Known/open issues are present on GitLab, so keep checking.
Always remember a structured email will help us understand your issues quickly.
