Embodiment 1

[0093] In this embodiment, the base station will be used as an example to illustrate the base station side. The embodiment also includes the process of handover, so as to understand more clearly the technology provided by the present invention when the channel information of two types of carriers can be accurately fed back. further use of the program.

[0094] Figure 4 It is a schematic diagram of the implementation process of the base station side in carrier switching, as shown in the figure, which may include:

[0095] Step 401, the base station determines a working carrier and a non-working carrier among all carriers;

[0096] Step 402, the base station instructs the UE on the channel information feedback mode of the working carrier and the non-working carrier;

[0097] In this step, when indicating the feedback mode, the base station may respectively configure the feedback modes of the working carrier and the non-working carrier. Among the separately configured feedbac...

Embodiment 2

[0135] Figure 6 It is a schematic diagram of the implementation process of the UE side in the carrier switching, as shown in the figure, which may include:

[0136] Step 601, the UE receives the channel information feedback mode of the working carrier and the non-working carrier indicated by the base station;

[0137] Step 602, the UE obtains the magnitude deviation X and the number M of carriers to be reported;

[0138] In this step, the UE may agree with the base station, or know the working carrier and non-working carrier indicated by the base station through high-level configuration and physical layer signaling. When selecting and reporting the channel information of the carrier with the best channel quality, a magnitude deviation of X is required. and report the number of carriers M;

[0139] Step 603, the UE processes the measured channel information of the working carrier and the non-working carrier;

[0140] In the processing process, it includes two parts: the wor...

Abstract

The invention discloses a method and equipment for reporting and receiving channel information of a multi-carrier system. The method comprises the following steps that: a base station side determines working carriers and non-working carriers in all carriers; the base station side instructs a first feedback mode of channel information of the working carriers and the non-working carriers to user equipment; when performing the first feedback mode, the user equipment degrades the channel information of the measured non-working carriers according to the magnitude deviation instructed in the channel information reported by the working carriers and the non-working carriers which are instructed in the first feedback mode; and the base station side receives the channel information of the working carriers and the non-working carriers which are reported by the user equipment, wherein the channel information is reported by the user equipment according to the first feedback mode. By the invention, the consistency with the current long term evolution (LTE) system can be kept, the acquisition of much channel information by the base station end can be guaranteed, the gain optimization of frequency selectivity of the system can be better guaranteed, limited fed-back resources are saved, and acquisition of the channel information of the non-working carriers in the carrier switchover can be guaranteed.

Description

technical field [0001] The invention relates to wireless communication, in particular to a method and device for reporting, receiving and processing channel information of a multi-carrier system. Background technique [0002] In the LTE-A (Long Term Evolution-Advance, Long Term Evolution) multi-carrier system, compared with the LTE (Long Term Evolution, Long Term Evolution) system, it needs to support a larger system bandwidth, which is initially set at 100 MHz at present. Based on the current spectrum resource allocation, the LTE-A system preliminarily defines that the acquisition of 100MHz resources is composed of several carrier parts, each carrier part ranges from 5-20MHz, and is continuously or discretely distributed in the entire spectrum resource depending on the specific situation. , and the characteristics of each carrier part are compatible with the existing LTE technical characteristics, figure 1 It is a schematic diagram of the spectrum aggregation system, for d...
