This TR is intended to capture the output of the study item on Signalling and procedure for interference avoidance for in-device coexistence, which was approved at TSG RAN#48.

The objective of the SI is to investigate suitable mechanisms for interference avoidance from signalling and procedure point of view to facilitate the coexistence scenario that LTE and GPS/ ISM radio within the same device working in adjacent frequencies or sub-harmonic frequencies. The work under this study should take the following steps:
  • Evaluate whether existing RRM mechanisms could be utilized to effectively solve the coexistence problems that arise in supporting the scenarios abovementioned and guarantee the required QoS in LTE with proper GPS/ISM operation.
  • If legacy signaling and procedure are not sufficient to ensure required performance in the interested coexistence scenario, study enhanced mechanisms to better avoid interference and mitigate the impact caused by ISM radio.
Impact on legacy LTE UEs should be minimized.
