Resource allocation method, first node, and second node

An apparatus, comprising:

• a processor coupled to a non-transitory memory, and configured to read instructions stored in the non-transitory memory, wherein the instructions comprise instructions for:
• receiving downlink control information from a second node, wherein the downlink control information comprises resource indication information, and the resource indication information indicates which of a plurality of resource allocation manners the apparatus will use for transmitting data;
• determining a first resource allocation manner of the plurality of resource allocation manners based on the resource indication information, wherein the first resource allocation manner is used to allocate a transmission resource greater than one narrowband;
• determining an allocated transmission resource based on the first resource allocation manner and the resource indication information;
• and
• transmitting the data using the allocated transmission resource.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer hardware of an apparatus, cause the apparatus to:

• receive downlink control information from a second node, wherein the downlink control information comprises resource indication information, and the resource indication information indicates which of a plurality of resource allocation manners the apparatus will use for transmitting data;
• determine a first resource allocation manner of the plurality of resource allocation manners based on the resource indication information, wherein the first resource allocation manner is used to allocate a transmission resource greater than one narrowband;
• determine an allocated transmission resource based on the first resource allocation manner and the resource indication information;
• and
• transmit the data using the allocated transmission resource.
