Abstract:
1. A method for generating a reference signal, comprising: receiving, by a user equipment from a base station, a first signal carrying reference signal solution information, wherein the reference signal solution information has at least one mapping relation with at least one piece of orthogonal code configuration information and at least one hopping mode, wherein the at least one mapping relation is stored at the base station and at the user equipment; determining, by the user equipment, a corresponding piece of the orthogonal code configuration information and a corresponding hopping mode according to the received reference signal solution information and the stored at least one mapping relation; and generating, by the user equipment, a reference signal according to the determined piece of the orthogonal code configuration information and the determined hopping mode, wherein before receiving, by the user equipment, the first signal, the method further comprises: receiving, by the user equipment from the base station, a second signal indicating a quantity of data transmission layers; and wherein the determining, by the user equipment, the corresponding piece of the orthogonal code configuration information and the corresponding hopping mode according to the received reference signal solution information and the stored at least one mapping relation comprises: determining, by the user equipment, at least one corresponding mapping relation from the stored at least one mapping relation according to the quantity of data transmission layers; and determining, by the user equipment, the corresponding piece of the orthogonal code configuration information and the corresponding hopping mode according to the reference signal solution information and the at least one determined corresponding mapping relation determined according to the quantity of data transmission layers, wherein different data transmission layers use a single orthogonal cover code when the orthogonal code configuration information includes the orthogonal cover code.
