Abstract
A reference signal multiplexing method for multiple mobile stations includes: grouping together control signals for the multiple mobile stations; and multiplexing reference signals corresponding to the control signals by CDM over the same bandwidth as that of grouped control signals.
Claims2
A method for multiplexing reference signals for a plurality of mobile stations, comprising:
- grouping together control signals to be transmitted by the plurality of mobile stations;
- and
- multiplexing reference signals corresponding to respective ones of the control signals by CDM (code-division multiplexing) over a same frequency bandwidth as a sum of bandwidths assigned to each of the control signals in the group.
A method for allocating a reference resource to reference signals for a plurality of mobile stations, comprising:
- grouping together control resources used for control signals to be transmitted by the plurality of mobile stations and
- allocating a reference resource to each of the reference signals corresponding to respective ones of the control signals, wherein a frequency bandwidth of the references resource is equal to a sum of bandwidths assigned to each of the control resources in the group.
