method for controlling access to a radio channel on a single frequency network, user equipment device and sfn-ra single frequency network radio access controller

摘要

The present invention provides a method for controlling access to a radio channel in a single frequency network in which multiple base stations simultaneously transmit the same data to a device, which method comprises transmitting from a first plurality of base stations. a set of random access parameters common to the first plurality of base stations of a single frequency network; receiving from a second plurality of base stations a random access preamble by the device eu, the second plurality of base stations being the same or a subset of the first plurality of base stations; transmitting a plurality of responses to the random access preamble from a third plurality of base stations in a single frequency network, the third plurality of base stations being the same as or a set of the second plurality of base stations; and receiving from a fourth plurality of base stations a programmed transmission in response to the plurality of responses, the fourth plurality of base stations being the same as a subset of the third plurality of base stations.
