Patent ID: 8259636

Claim:
A method for communicating data in a Multicast-Broadcast Single Frequency Network MBSFN telecommunication network comprising at least one primary station, and a plurality of secondary stations, said method comprising at a secondary station, responsive to reception of a broadcast or multicast message, the steps of: a) receiving one of a broadcast message or a multicast message at a secondary station in one of a point-to-multipoint from multi-cells PTM-MC configuration or point-to-multipoint from single cell PTM-SC configuration, b) selecting a Random Access Channel RACH preamble signature at the secondary station associated with a specific MBMS service ID in the received message in the case where the received message is a multicast message, c) reusing part of a dedicated uplink feedback mechanism to transmit a feedback signal to the primary station by means of a feedback resource of a random access channel (RACH), said feedback resource being allocated commonly for a set of secondary stations, d) provisioning two types of RACH resources by the MBSFN network dependent upon the type of feedback signal received from the secondary station, a first type of RACH resource allocated for unicast configurations and a second type of RACH resource allocated for PTM random access preambles wherein the feedback signal is one of a dedicated type related to at least one point to point link between the secondary station and the primary station, the feedback signal being addressed to the primary station, or of a common type related to a multicast link, the feedback signal being addressed to a network controller linked to the primary wherein said feedback signal is transmitted as a common type in the case where the received message is a multicast message, wherein said feedback signal is transmitted as the dedicated type in the case where the received message is a broadcast message wherein both the common type and dedicated type of RACH resources are dynamically adjusted by the MBFSN network according to the type of feedback from the secondary stations or the number of secondary stations providing feedback.
