摘要： Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.

摘要： A method in a radio network node for transmitting a reference signal over an antenna port includes transmitting the reference signal over a first code division multiplexing (CDM) subgroup using an orthogonal cover code. The first CDM subgroup includes a first set of resource elements in a first time slot and a second set of resource elements in a subsequent time slot. The radio network node selects a permutation of the orthogonal cover code and transmits the reference signal over a second CDM subgroup using the permutation. The second CDM subgroup includes a third set of resource elements in the first time slot and a fourth set of resource elements in the subsequent time slot. The permutation is selected to enable decoding of the reference signal in the frequency domain, by applying the orthogonal cover code to the first set resource elements and to the third set of resource elements.
