Resource allocation indication information communication method, apparatus and system

A wireless apparatus, comprising:

• one or more processors;
• and
• a memory, wherein the memory stores a computer program, and when executing the computer program stored in the memory, the one or more processors executes operations comprising:
• receiving resource indication information, wherein the resource indication information indicates frequency domain resources of a data channel;
• and
• determining the frequency domain resources of the data channel based on the resource indication information and a common index area, wherein:
• the resource indication information comprises S bits, and S is a positive integer,
• a most significant bit (MSB) in the S bits indicates whether a resource block set belongs to the frequency domain resources of the data channel,
• the resource block set consists of n consecutive resource blocks within a bandwidth part (BWP), n is greater than zero, and a start resource block of the resource block set is a start resource block of the BWP, and
• when n<m, n is equal to m minus y2, wherein y2 is equal to an offset mod m, y2 is nonzero, the offset is an offset between a start resource block of the common index area and the start resource block of the BWP, m is a positive integer, and m is a resource block group (RBG) size corresponding to a bandwidth of the BWP;
• and
• when the data channel is a physical uplink shared channel (PUSCH), sending data on the frequency domain resources of the data channel;
• or when the data channel is a physical downlink shared channel (PDSCH), receiving, data on the frequency domain resources of the data channel.

A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause a user equipment (UE) to perform operations comprising:

• receiving resource indication information, wherein the resource indication information indicates frequency domain resources of a data channel, the resource indication information comprises S bits, and S is a positive integer;
• and
• determining the frequency domain resources of the data channel based on the resource indication information and a common index area;
• wherein:
• a most significant bit (MSB) in the S bits indicates whether a resource block set belongs to the frequency domain resources of the data channel,
• the resource block set consists of n consecutive resource blocks within a bandwidth part (BWP), n is greater than zero, and a start resource block of the resource block set is a start resource block of the BWP, and
• when n<m, n is equal to m minus y2, wherein y2 is equal to an offset mod m, y2 is nonzero, the offset is an offset between a start resource block of the common index area and the start resource block of the BWP, m is a positive integer, and m is a resource block group (RBG) size corresponding to a bandwidth of the BWP;
• and
• when the data channel is a physical uplink shared channel (PUSCH), sending data on the frequency domain resources of the data channel;
• or when the data channel is a physical downlink shared channel (PDSCH), receiving data on the frequency domain resources of the data channel.
