UE-RS sequence initialization for wireless communication systems

A method of data communication in a wireless communication system, comprising:

• receiving at least one pseudo-random sequence from a plurality of pseudo-random sequences, each pseudo-random sequence of the plurality of pseudo-random sequences corresponding to a of a plurality of user equipment specific reference signal (UE-RS) for use by at least one user equipment (UE), each pseudo-random sequence having been initialized independent of a specific UE identifier and independent of a resource bandwidth assigned to a specific UE, and each pseudo-random sequence having been initialized based at least in part on a group ID corresponding to a UE group to which the at least one UE is assigned;
• receiving data on a downlink bandwidth resource;
• and
• using the UE-RS to decode data received on the downlink bandwidth resource.

An apparatus in a wireless communication network, comprising:

• at least one processor configured to:
• initialize a plurality of pseudo-random sequences, each pseudo-random sequence of the plurality of pseudo-random sequences corresponding to a user equipment specific reference signal (UE-RS) for use by at least one user equipment (UE) from a plurality of UEs, the initialization of each pseudo-random sequence being independent of a specific UE identifier and independent of a resource bandwidth assigned to a specific UE, and the initialization being based at least in part on a group ID corresponding to a UE group to which the at least one UE is assigned,
• generate the plurality of pseudo-random sequences, and
• map at least one of the plurality of pseudo-random sequences to a portion of common resources for at least one UE among the plurality of UEs.
