      hotfix: better CQI requests, especially for TDD · 2a7ac81b
      Cédric Roux authored
      In TDD mode, CQI requests are not possible in special subframes (at
      least for some TDD configurations, see 36.213 7.2.3 that says "a
      DL subframe is valid if it does not contain a DwPTS field if the
      length is less than  7680 Ts").
      In the code, we simply disable CQI requests in special subframes,
      no matter what the length of DwPTS.
      A problem can arise if the DCI0 for a given UE are sent only in
      those special subframes. In this case the UE will never report
      CQI and the eNB will use low MCS for this UE, impacting performances.
      Another, related, problem is when there are several UEs. There again
      one UE might always get its DCI0 in special subframes and thus never
      report CQI. There again, performance issues.
      This commit is an attempt to improve the situation.
      It does two things.
      1 - tag the UE as schedulable in the function UE_is_to_be_scheduled
          if the cqi_req_timer is expired
      2 - use cqi_req_timer as a criterium when ordering UEs for UL scheduling
      The value chosen for the expiration of the cqi_req_timer in
      UE_is_to_be_scheduled is quite high (300) because as the code is
      today we may overschedule the UE for short bursts until we receive
      a CQI from the UE. [TODO: fix the code properly to avoid this behavior.]
      Note: the fairRR scheduler has not been analyzed and this commit may
            not fix anything in case the fairRR scheduler is used.

      CI: first scripts for Inria R2LAB deployment · c86f8d65
      Raphael Defosseux authored
        -- Adding the python framework of build and test to inria r2lab pipeline
        -- R2LAB pipeline has logCollections and artifacts storing
        -- Python framework should support latest Rel14 OAI openair-cn/cn-cups EPC
        -- Pipeline uses the latest version of booking-lease script (by duration)
        -- Support for distributed smartphone adb servers
        -- Initial scenarios:
           ** Build on one OAI 4G eNB and one OAI 4G UE
           ** Test in FDD band7 / 5MHz / TM1 in noS1 configuration
           ** Test in FDD band7 / 5MHz / TM1 with latest OpenAir-CN-CUPS --> just attachment
