Method of Resource Allocation, System and Transmitter

A transmitter, comprising:

• a scheduling unit for scheduling a plurality of receivers according to the request for transmitting uplink data sent by the plurality of receivers, so as to preliminarily determine the uplink shared transmission channel resources of the plurality of receivers;
• the uplink shared transmission channel resources used by one receiver being determined by a lowest resource block index and the number of the resource blocks that are allocated virtually continuously;
• a resource allocating unit for determining, respectively for each of the plurality of receivers, the uplink shared transmission channel resources, the used mapping relation of resources and the final cyclic shift n(DM_RS) for indicating an uplink feedback channel, according to the result of scheduling, a predefined mapping relation of resources, a spare mapping relation of resources and the n(DM_RS);
• wherein the mapping relation of resources refers to the relation between the index of the lowest resource block, the cyclic shift n(DM_RS) and group number and sequence index within the group of the feedback channel;
• and
• a resource notifying unit for notifying the plurality of receivers of the determined uplink shared transmission channel resources of the plurality of receivers determined by the resource allocating unit, the used mapping relation of resources and the final cyclic shift n(DM_RS).
