Embodiment Construction
[0073] In the embodiment of the present invention, when the PHICH is repeated, the UEs of all the Q (or I) PHICHs are remapped at the same time, and the I / Q leakage is randomized, so as to alleviate the PHICH detection performance degradation caused by the I / Q leakage. problem, thereby improving the detection performance of PHICH.
[0074] see image 3 , is a flowchart of an embodiment of the PHICH remapping method of the present invention, including:
[0075] S301: Using the orthogonal sequence number n in the PHICH group PHICH seq , to distinguish between Q-way PHICH and I-way PHICH;
[0076] Still taking Table 1 as an example, for ordinary CP, n PHICH seq = 0 ~ 3 The PHICH is the I-way PHICH, n PHICH seq = 4 ~ 7 The PHICH is the Q-path PHICH; for the long CP, n ...
