Embodiment 1

[0124] In this embodiment, Set is configured independently, including the case of feeding back category information. The base station can pre-configure N parameter sets Sets to the UE through high-level RRC signaling. The content of the N Sets can be flexibly configured. For example, it can be 2 Sets, as shown in Table 4; it can be 4 Sets The situation, as shown in Table 5:

[0125] Table 4

[0126] Set1 Feedback category: Class A Other parameter configuration 1 Set2 Feedback category: Class B Other parameter configuration 2

[0127] table 5

[0128] Set1 Feedback category: Class A Other parameter configuration 1 Set2 Feedback category: Class B Other parameter configuration 2 Set3 Feedback category: Class A Other parameter configuration 3 Set4 Feedback category: Class A Other parameter configuration 4

[0129] The base station indicates the Set selection information through the physical layer control si...

Embodiment 2

[0196] In the embodiment of the present invention, the triggers of Set and Process are jointly configured.

[0197]A case where the feedback category information is included. The base station can pre-configure N Sets to the UE through high-level RRC signaling. The content of the N Sets can be flexibly configured. For example, it can be 2 Sets, as shown in Table 26; it can also be 4 Sets. situation, as shown in Table 27:

Embodiment 3

[0268] In this embodiment, the case where multiple Processes are jointly triggered is described. The base station can trigger one or more CSI Process sets at the same time, and can also trigger CSI feedback corresponding to multiple different parameters under one Process at the same time; the base station configures the base station to use by configuring the signaling corresponding to 4 CSI Process set trigger indications and the joint parameter Set in advance Bitmap signaling indicates CSI Process set triggering and corresponding parameter joint configuration; as shown in Figure 4(a) and Figure 4(b).

[0269] The terminal receives the base station configuration signaling to obtain the joint coding information of the Process and the parameter Set, and the terminal receives the CSI Process set trigger indicated by the bitmap signaling and the corresponding parameter joint configuration information; obtains the triggered Process and the corresponding parameter Set; here, the para...

Abstract

The invention provides an information notification method and a channel state information CSI process execution method. The information notification method includes acquiring a plurality of parameter sets, wherein the parameter sets are composed of one or more types of CSI parameters for indicating the channel state information CSI measurement and / or feedback; and sending the parameter set, corresponding to the CSI process, of the plurality of parameter sets to a terminal. According to the invention, the technical problem that the standard transparency technology in the prior art cannot be realized, and the technical effect that the CSI parameters are flexibly configured to realize the standard transparency technology is achieved.

Description

technical field [0001] The present invention relates to the field of communication, in particular to an information notification method and an execution method of a channel state information CSI process. Background technique [0002] In a wireless communication system, the transmitting end and the receiving end generally use multiple antennas to transmit and receive to obtain a higher rate. One of the principles of multi-antenna technology is to use some characteristics of the channel to form multi-layer transmission that matches the characteristics of the channel. The radiation direction of the signal is very targeted, which can effectively improve the system performance and obtain significant performance without increasing the bandwidth and power. The performance improvement of is a very promising technology, which is widely used in current systems. The data transmission performance of a multi-antenna system mainly depends on the measurement and feedback of channel state ...
