WF on Channel Modeling Requirements Huawei, HiSilicon, Ericsson, Keysight, CMCC, […] R GPP TSG RAN1#84 St Julian’s, Malta, Feb , 2016 Agenda Item:

2 Requirements (1/2) Support frequency range up to 100 GHz. The joint propagation characteristics over different frequency bands will need to be evaluated for multi-band operation. Take care of mmW propagation aspects such as blocking and atmosphere attenuation. Aim for the channel model to cover a range of coupling loss considering current typical cell sizes, e.g. up to km-range macro cells. Note: This is to enable investigation of the relevance of the 5G system using higher frequency bands to existing deployments. Support large channel bandwidths (up to 2GHz) Support large antenna arrays Angular resolution of the channel down to around 1.0 degree Support different array types and spherical waves Accommodate mobility Mobile speed up to [350] km/h. [Methodology should support possible future extension to D2D and V2V.] or [Develop a methodology considering that model extensions to D2D and V2V may be developed in future SI.]

3 Requirements (2/2) The model can be used to support studies of e.g. massive MIMO, MU-MIMO, [D2D,] mobility and beam tracking, etc. The model should be consistent in space, time and frequency The model should ensure that the channel states in transitions (LOS/NLOS, indoor/outdoor, etc) change smoothly as a function of time and position. The model should ensure the large scale and small scale parameters such as AoA/AoD and delay characteristics are consistent between closely located transceivers. Channel model SI should take into account the outcome of RAN-level discussion in the ‘5G’ requirement study item Complexity in terms of Description, Generating channel coefficients, and Simulation time should be reasonable.
