Claim 20:
21. A method for receiving a plurality of data blocks from other data communication apparatuses at a data communication apparatus, wherein the data blocks are represented by transmission symbols of multiple groups of transmission symbol positions within a frame comprising a two-dimensional grid of transmission symbol positions,
wherein the method comprises signaling to the other data communication apparatuses which group of transmission symbol positions should be used by which of the other data communication apparatuses,
wherein the method comprises providing an information describing a group of transmission symbol positions to be used by a given one of the other data communication apparatuses, and an information describing a desired relative position of reference symbol positions with respect to the group of transmission symbol positions to be used by the given one of the other data communication apparatuses;
wherein the method comprises providing, in at least one of the possible communication states, a communication resource information which indicates that a reference symbol position is located at a beginning of a group of transmission symbol positions to be used by one of the other data communication apparatuses;
wherein the method comprises selectively providing the information describing a desired relative position of reference symbol positions with respect to the group of transmission symbol positions to be used by the given one of the other data communication apparatuses as a 1-bit information in case the respective group of transmission symbol positions comprises 2 transmission symbol positions and as a 2-bit information in case the respective group of transmission symbol positions comprises more than 2 transmission symbol positions; or
wherein the method comprises selectively providing the information describing a desired relative position of reference symbol positions with respect to the group of transmission symbol positions to be used by the given one of the other data communication apparatuses as a 1-bit information or as a 2-bit information in dependence on a temporal extension of the respective group of transmission symbol positions.
