Title:
METHOD AND DEVICE FOR INDICATING AND DETERMINING PRE-CODING VECTOR
Document Type and Number:
WIPO Patent Application WO/2018/196628
Kind Code:
A9
Abstract:
The embodiments of the present application relate to pre-coding technology, and disclosed thereby are a method and device for indicating and determining a pre-coding vector, which may help to implement the following beneficial effects: on the basis of ensuring the accuracy of the pre-coding vector, the overhead of indication information for a feedback indication superposition coefficient is reasonably configured, thus improving the overall performance gain of a system. Said method may comprise: generating indication information, and sending the indication information. The indication information is used to indicate the plurality of component vectors of an ideal pre-coding vector and a superposition coefficient of each component vector, wherein the superposition coefficient of a component vector comprises at least one of the following types: a wideband amplitude coefficient, a narrowband amplitude coefficient, and a narrowband phase coefficient; the quantization bits of the superposition coefficients of the same type of at least two component vectors other than normalized reference component vectors in the plurality of component vectors are different.
