Abstract
A method of mapping symbols of a physical control format indicator channel (PCFICH) is described. A start position of a resource element to map the symbols for the PCFICH is determined by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink. The symbols are mapped in the start position. Therefore, a problem of wasting resource elements or not being able to implement mapping can be solved by applying a simple mapping rule while mapping symbols of the PCFICH.
Claims9
A method of mapping symbols of a physical control format indicator channel (PCFICH) in units of a resource element group, the method comprising:
- determining a start position of a resource element to map the symbols for the PCFICH by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink;
- and
- mapping the symbols in the start position.
A method of mapping symbols of a physical control format indicator channel (PCFICH) in units of a resource element group, the method comprising:
- if the number of resource blocks is an odd number, determining a start position of a resource element to map the symbols for the PCFICH using a variable obtained by subtracting 1 from the number of resource blocks, wherein the resource blocks are transmitted in downlink;
- and
- mapping the symbols in the start position.
