Selective mapping of coded multi-channel transmission

A particular user device of a multiuser communication system, the particular user device comprising:

• at least one processor;
• memory;
• and
• program instructions stored in the memory that, when executed by the at least one processor, cause the particular user device to:
• selectively partition a sequence of coded bits from a particular bit stream into a sequence of fixed length blocks of coded bits;
• sparsely map at least the sequence of fixed length blocks of coded bits into a resource block, wherein symbols of the resource block have a specified bit loading;
• and
• transmit the resource block via an uplink channel to a receiver of a base station of the multiuser communication system;
• wherein the particular bit stream is one of a plurality of bit streams to be transmitted to the receiver of the base station in coordination therewith, one or more of bit streams of the plurality of bit streams are generated in other user devices apart from the particular user device, and the selective sparse mapping involves selectively not mapping bits from the particular bit stream onto certain symbol positions of the resource block.

A multiuser communication system comprising:

• a first user device configured to:
• selectively partition a sequence of coded bits from a particular bit stream into a sequence of fixed length blocks of coded bits;
• sparsely map at least the sequence of fixed length blocks of coded bits into a resource block, wherein symbols of the resource block have a specified bit loading;
• and
• transmit the resource block via an uplink channel to a receiver of a base station of the multiuser communication system;
• wherein the particular bit stream is one of a plurality of bit streams to be transmitted to the receiver of the base station in coordination therewith, one or more of bit streams of the plurality of bit streams are generated in other user devices apart from the particular user device, and the selective sparse mapping involves selectively not mapping bits from the particular bit stream onto certain symbol positions of the resource block;
• and
• a second user device configured to:
• transmit a second bit stream of the plurality of bit streams, wherein a sparse mapping on the second user device is different from the sparse mapping on the particular user device.
