64QAM use in the downlink is an attractive complement to multi-antenna techniques (MIMO) in the downlink, e.g. in scenarios where deployment of MIMO is not possible. The combination of 64QAM and MIMO allows for further increased user throughput in favourable radio conditions such as in well tuned outdoor systems or indoor system solutions (cells with isolation).

This work provides support of 64QAM as a downlink modulation scheme for HSDPA in FDD in combination with MIMO for Type II/III UEs, building upon provisions taken together with the introduction of 64QAM support. This specification includes:

  • L1 aspects of 64QAM combined with MIMO

  • L2/L3 aspects of 64QAM combined with MIMO

  • Iub/Iur support for 64QAM combined with MIMO

  • BS and UE requirements for 64QAM combined with MIMO for an agreed set of radio conditions/environments.

  • Requirement set point to take the BTS impairments into account
