Embodiment 1

[0056] In this embodiment, an information transmission method is provided, figure 1 is a flowchart of an information transmission method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0057] Step S102, the terminal reports Channel Quality Indicator (CQI, Channel Quality Indicator) information to the base station via a periodic and / or aperiodic manner, wherein the target transmission error rates corresponding to the Channel State Information (CSI) reported at different times are not all the same . The transmission error rate can be block error rate BLER, bit error rate BER, bit error rate, etc. In this embodiment, BLER is used as an example for description, and CSI includes at least CQI. In this embodiment, CQI is used as a preferred implementation mode for description . The CSI information includes at least CQI information, and may also include precoding matrix indication PMI, rank indication RI in...

Embodiment 2

[0102] In this embodiment, an information transmission device is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0103] figure 2 is a structural block diagram of an information transmission device according to an embodiment of the present invention, such as figure 2 As shown, applied to the terminal, the device includes:

[0104] The reporting module 20 is configured to report channel state information (CSI) to the base station in a periodic and / or aperiodic manner, wherein the target transmission error rates corresponding to the CQI inform...

Embodiment 3

[0116] This embodiment proposes an information transmission method, which reports CQI for different target BLERs in a periodic and / or aperiodic manner, and the periodic and aperiodic reporting methods are as follows:

[0117] 1. Periodic reporting method

[0118] Mode 1-1: The CQI reporting period of the multi-target BLER is the same as that of the single-target BLER reporting CQI.

[0119] 1-1(a): The reporting CQI period corresponding to each target BLER is the same. image 3 It is a schematic diagram of reporting periodic CSI according to the embodiment of the present invention and different target BLERs correspondingly report the same CQI period, as shown in image 3 shown.

[0120] 1-1(b): The reporting CQI period corresponding to each target BLER is different, preferably the reporting CQI period corresponding to the lower target BLER is an integer multiple of the reporting CQI period corresponding to the existing target BLER. Figure 4 It is a schematic diagram of per...

Abstract

The invention provides an information transmission method and apparatus. The method includes: a terminal reports channel state information (CSI) to a base station in a periodic and / or non-periodic manner, wherein the target transmission error rates corresponding to the CSI reported at different moments are not totally the same. According to the method and apparatus, the technical problem of low system frequency spectrum efficiency during transmission employing the same target BLER in the related technology is solved.
