RANDOM ACCESS TO THE TP SELECTED BASED ON RECEPTION TIMING

摘要

The present document is directed to a reception timing based TP (Transmission Point) selection and a random access procedure to the selected TP. According to one embodiment, a method comprises transmitting a random access preamble to the macro eNB and the RRHs; receiving a random access response, during a predetermined period of time after transmitting the random access preamble, from the macro eNB, wherein the random access response comprises a timing advanced command value and information about a specific transmission point (TP) to which the timing advanced command value corresponds, wherein the specific TP is selected from the macro eNB and the RRHs; and transmitting a message 3 to the specific TP based on the received timing advanced command value.
