This document is a technical report which was requested in the Objective of the RAN4 work item description "1.28Mcps TDD Home NodeB RF requirements" [1]. The goal of this technical report is to describe the agreed approach towards the RF related issues raised in [1]:

1. The existing 1.28Mcps BS classes did not fully address the RF requirements of the Home NodeB application. Proposals for changes to radio performance requirement specifications TS 25.105 are therefore provided in this report, together with the proposals for the test specification TS 25.142.
2. The report intends to provide guidance to mitigate interference and clarify some interference cases
