Abstract:
A method for controlling access to a radio channel in a single frequency network in which multiple base stations transmit the same data simultaneously to a user equipment, UE device, includes a first plurality of base stations transmitting a set of random access parameters of the single frequency network. The method also includes a second plurality of base stations receiving a random access preamble transmitted by the UE device. The second plurality of base stations the same or a subset of the first. The method also includes transmitting responses to the random access preamble from a third plurality of bases stations. The third plurality of base stations the same as or a subset of the second. The method also includes a fourth plurality of base stations receiving a scheduled transmission in response to the responses. The fourth plurality of base stations the same as or a subset of the third.
