METHOD FOR COMMUNICATING USING OUTDATED CHANNEL STATE INFORMATION IN A 2-CELL 2 USER CELLULAR NETWORK

摘要

Methods of communicating using outdated CSI for a UE and a BS are disclosed. The method for a UE comprises transmitting to a first BS 4 different linear combinations at each of 4 time slots included in a first time period, receiving from a second BS feedback signals for the linear combinations and transmitting to the first BS a reconstruction signal generated based on the feedback signals at a first time slot of a third time, wherein the feedback signals comprise channel coefficients information between the first UE and the second BS during the first time period.
