Abstract: |
Wireless
communication platforms in small enclosures are susceptible to in-device RF
interference. Difficult interference cases emerge in the next-generation 4G smartphones using certain LTE bands, and support in MAC and
higher protocol layers is required for efficient interference avoidance.
Interference and the avoidance mechanisms create coupling between the radios
complicating the interaction between the smartphone
radios and their respective networks. Therefore, the purely analytical
approach for studying radio performance becomes difficult. In
this paper we present RCOEX, an in-device coexistence simulator for the MAC
layer. RCOEX simulates simple multi-network setups focusing on various in-device
coexistence mechanisms and their performance. The simulation uses the discrete
event variable time-delta model. As the protocol models are complex entities with
non-trivial interaction, extensive effort has been made to support rich
programming environment, including transceiver emulation, threads, and
complex event filtering. Within this framework, we study the design of the WiFi model in more detail. |
