Claim of US Patent No. 10,397,911

1. A user equipment (UE) which is operable to communicate with a communication node, the UE comprising:a receiving circuit configured to receive control data defining an allocation of at least one resource block for use in transmitting uplink data, wherein the at least one resource block comprises at least one of a plurality of resource blocks that are numbered in a frequency domain, and to receive, in a transmission separate from the control data, a parameter representing a configuration of resources to be used for an ACK/NACK channel;
a transmitting circuit configured to transmit the uplink data using the at least one resource block for use in transmitting uplink data; and
a processor configured to determine a position of at least one ACK/NACK channel resource based on:
a value derived from a position, in the frequency domain, of a single resource block allocated for a corresponding uplink data transmission, added to a value derived from a function of the received parameter representing the configuration of the resources to be used for the ACK/NACK channel and a total number of resource blocks in a downlink bandwidth;
wherein the receiving circuit is configured to receive at least one ACK/NACK the ACK/NACK channel using the at least one ACK/NACK channel resource.
