Method and apparatus for rate matching in a telecommunications system

An apparatus for converting an input data rate associated with N units of data to an output data rate associated with M units of data, comprising:

• means for calculating, for N values of input data, N write-control parameters each associated with one of M addresses of an output memory;
• means for directing each of the N values of input data to its associated address of the M addresses of the output memory in response to the N calculated write-control parameters;
• and
• means for reading the output memory to provide output data associated with the output data rate,
• wherein, if N is greater than M, some of the N write-control parameters are associated with at least one shared address of the M addresses, and, if M is greater than N, all of the N write-control parameters are associated with different addresses of the M addresses.

A method for converting N values of data to M values of data, comprising:

• calculating, for the N values of data, N write-control parameters each associated with one of M addresses of a memory;
• directing each of the N values of data to its associated address of the M addresses of the memory in response to the N calculated write-control parameters;
• and
• reading the memory to provide the M values of data,
• wherein, if N is greater than M, some of the N write-control parameters are associated with at least one shared address of the M addresses, and, if M is greater than N, all of the N write-control parameters are associated with different addresses of the M addresses.
