During the UTRA standards development, the physical layer parameters will be decided using system scenarios, together with implementation issues, reflecting the environments that UTRA will be designed to operate in.
The present document discusses system scenarios for UTRA operation primarily with respect to the radio transmission and reception. To develop the UTRA standard, all the relevant scenarios need to be considered for the various aspects of operation and the most critical cases identified. The process may then be iterated to arrive at final parameters that meet both service and implementation requirements.
Each scenario has four clauses:
  1. lists the system constraints such as the separation of the MS and BTS, coupling loss;
  2. lists those parameters that are affected by the constraints;
  3. describes the methodology to adopt in studying the scenario;
  4. lists the inputs required to examine the implications of the scenarios.
The following scenarios will be discussed for FDD and TDD modes (further scenarios will be added as and when identified):
  1. Single MS, single BTS;
  2. MS to MS;
  3. MS to BS;
  4. BS to MS;
  5. BS to BS.
These scenarios will be considered for coordinated and uncoordinated operation.
