1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions, that when executed by the at least one processor, cause the apparatus at least to:
determine a resource pattern in a set of transmission resources,
wherein said resource pattern is associated with a further apparatus of a group of apparatus;
transmit data to the group of apparatus; and
receive transmission feedback from each of the group of apparatus, said group of apparatus comprising the further apparatus; and
determine the resource pattern in the set of transmission resources in dependence upon an identifier of the further apparatus,
wherein the received transmission feedback comprises an activation pattern that matches the resource pattern that is determined associated with the further apparatus,
wherein the transmission feedback received from the further apparatus comprises
overlap in transmission resources with the transmission feedback received from other apparatus of said plurality group of apparatus;
receive the identifier of the further apparatus;
wherein the resource pattern is determined in the indicated set of resources with application of at least one hash function to the identifier to output index positions into the set of transmission resources, and
wherein the transmission feedback comprises at least one of: acknowledgments or
negative acknowledgements.
