METHOD, APPARATUS, SYSTEM AND RELATED COMPUTER PROGRAM PRODUCT FOR RESOURCE ALLOCATION

摘要

FIELD: information technology. ^ SUBSTANCE: respective demodulation reference signals (DM RS) of a user bandwidth can be cyclically shifted with respect to each other. An uplink scheduling grant may include an index for a DM RS resource having a cyclic shift and an orthogonal cover code or interleaved frequency division multiple access (IFDMA) comb, wherein use of the orthogonal cover or IFDMA comb may be configured using a radio resource control message. Use of the orthogonal cover or IFDMA comb may additionally be tied statically into DM RS resources. At least some of respective demodulation reference signals of at least two user bandwidths may be mutually orthogonal. ^ EFFECT: efficient use of multiband transmission in a multiple-input and multiple-output system. ^ 23 cl, 8 dwg
