Abstract:
1. A method of data communication in a wireless communication system, comprising: initializing 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; generating the plurality of pseudo-random sequences; and mapping 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.
