Methods, apparatuses, system, and related computer program product for resource allocation

摘要: Embodiments provide a method and apparatus wherein respective demodulation reference signals, DM RS, of user bandwidth can be cyclically shifted with respect to each other. An uplink scheduling grant may comprise an index for RS resource having cyclic shift orthogonal cover code or interleaved frequency division multiple comb usage configured using radio control message. A optionally tied statically into resources. At least some signals the at two bandwidths mutually orthogonal.
