Embodiment 1

[0386] In this embodiment, the base station first determines the configuration information of the CSI-RS, then generates signaling including the configuration information of the CSI-RS, and then transmits the signaling including the configuration information of the CSI-RS. Wherein, for example, a bit (bit) is used to indicate the number of ports, b is the number of components of the pilot resource pattern, c bit is used to indicate the number of ports of the pilot resource pattern component, and d bit is used to indicate the sorting method of the CSI-RS ports, where a+b +c+d=X.

[0387] Alternatively, a bit may also be used to represent the number of ports, b bit represents the joint coding of the number of pilot resource pattern components and the number of ports representing the pilot resource pattern components, and c bit represents the CSI-RS port sorting method, wherein, a+ b+c=X.

[0388] Alternatively, the X bit may also be used to represent the joint coding of the por...

Embodiment 2

[0393] In this embodiment, (N, K) has Q kinds of candidate values, and the Q kinds of values ​​are divided into X sets, and each set adopts a type of CSI-RS port sorting method, and the CSI-RS port sorting methods used in different sets The modes are different; Q and X are integers greater than 1. For example (N, K)=(8,2) is a set corresponding to the aforementioned sorting method A1, (N, K)=(2,8) is a set corresponding to the aforementioned sorting way A3, (N, K)=( 4, 3) is a set corresponding to the aforementioned sorting mode A5, where (8, 2), (2, 8), and (4, 3) are respectively a set. Or (N, K)=(8,2) is a set corresponding to the aforementioned sorting mode A1, (N, K)=(2,8) is a set corresponding to the aforementioned sorting mode A3, (N, K)=( 2, 6) is a set corresponding to the aforementioned sorting method A3, where (8, 2) is a set, and (2, 8) and (2, 6) are another set

Embodiment 3

[0395] In this embodiment, (N, K) has Q kinds of candidate values, and the Q kinds of values ​​are divided into three sets, the first set uses the first type of CSI-RS port sorting method, and the second set uses the second type of CSI -RS port sorting method, the third type of set adopts the first type of CSI-RS port sorting method or the second type of CSI-RS port sorting method, the first type of CSI-RS port sorting method and the first type of CSI-RS port sorting method different.

[0396] For example, the CSI-RS port sorting method of the first pattern set adopts the A2 sorting method, the CSI-RS port sorting method of the first pattern set adopts the A4 sorting method, and the CSI-RS port sorting method of the first pattern set can be adopted. A2 can also adopt A4; the CSI-RS port sorting method of the first pattern set adopts the A4 sorting method, the CSI-RS port sorting method of the first pattern set adopts the A2 sorting method, and the CSI-RS port sorting method of...

Abstract

The present invention provides a channel state measurement pilot configuration method and device, analysis method and device, wherein the configuration method includes: base station configuring channel state measurement pilot CSI-RS configuration information; base station generating CSI-RS The signaling of configuration information; the base station sends signaling; wherein, the configuration information includes at least one of the following: the number of CSI-RS ports, the number K of pilot resource pattern components, the number N of ports of pilot resource pattern components, CSI ‑RS port sorting method; CSI‑RS port sorting method has M-type candidate port sorting methods, and M, K, and N are positive integers respectively. The present invention solves the problem that the numbering or sorting of the antenna ports in the related art cannot reflect the positional relationship and polarization attribute relationship of the antenna in the actual topological relationship, thereby improving the accuracy of the feedback channel and making full use of the power of signal transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a channel state measurement pilot configuration method and device, and an analysis method and device. Background technique [0002] Long Term Evolution (LTE for short) / LTE-Advanced (LTE-A for short) technology is a mainstream fourth generation mobile communication technology (4G). LTE / LTE-A is divided into the following two different duplex modes: Frequency Division Duplex (FDD for short) and Time Division Duplex (TDD for short). The frame structure of the frequency division duplex mode is called the first type frame structure (Frame structure type 1), and the frame structure of the time division duplex mode is called the second type frame structure (Frame structure type2). [0003] figure 1 is a schematic diagram of the first type of frame structure in the related art, such as figure 1 As shown, the description of the first type frame structure is as follows: each wireless ...
