Embodiment 1

[0189] This embodiment provides an information transmission method, which can be applied to the above-mentioned various transmission scenarios, such as a scenario where multiple DCIs correspond to multiple TRPs, or a DPS scenario, where DCIs can schedule data of different TRPs at different times, and the UE determines the The specific process of using the spatial correlation parameters is as follows:

[0190] Such as Figure 4 As shown, the method provided in this embodiment includes:

[0191] Step 101: the base station sends first signaling.

[0192] Wherein, the first signaling includes a first field, the state value of the first field is used to indicate the reception of the first spatial correlation parameter of the first channel, and the state value of the first field is the first One of a plurality of candidate state values ​​corresponding to a field, at least one state value in the plurality of candidate state values ​​corresponds to two or more spatial correlation pa...

Embodiment 2

[0313] This embodiment is similar to Embodiment 1, the difference is that in the second signaling sent by the base station in step 102, among the M spatial correlation parameter sets configured by the second signaling, at least two spatial correlation parameter sets of at least one spatial correlation parameter set The relevant parameter corresponds to at least one state value among the plurality of candidate state values ​​in the first field, for example, the TCI field state value "000" corresponds to TCI state IDs c1 and c9.

[0314] In this case, the data scheduled by a DCI comes from two different TRPs, that is, the noncoherent joint transmission (NCJT) scenario, in which the base station configures the association relationship, and the UE determines the process of the target spatial correlation parameters Specifically include:

[0315] see Figure 7 , Step 201: the base station sends first signaling.

[0316] This step is the same as step 101 in the first embodiment, an...

Embodiment 3

[0402] This embodiment also provides another information transmission method, which is used for instructing to select currently scheduled target space-related parameters in a scenario where data scheduled by a DCI comes from a single or multiple TRPs.

[0403] Specifically, the method provided in this embodiment may be applied in technical scenarios of dynamically selecting a transmitting node (Dynamic point selection, DPS) and NCJT. And one DCI signaling schedules a piece of data, and the data can come from different TRPs, that is, the NCJT transmission mode; or one DCI signaling schedules a piece of data that may come from one TRP or another dynamic TRP.

[0404] In this embodiment, the description is directed to "Case 1" of the first and second embodiments above. The difference from the above embodiment is that in the M space-related parameter sets configured by the base station, the candidate status value of each first field can indicate At least one TCI state ID, and the ...

Abstract

An information transmission method, device and equipment are disclosed, the method includes: a terminal receives a first signaling, the first signaling includes a first word field, and the state value of the first word field is used to indicate the reception of the first The first spatial correlation parameter of a channel, the state value of the first field is one of a plurality of candidate state values ​​corresponding to the first field, and at least one state value in the plurality of candidate state values Corresponding to two or more spatial correlation parameters; the terminal acquires one or more target spatial correlation parameters in the first spatial correlation parameters, and receives the first channel according to the one or more target spatial correlation parameters. In this method, by receiving the first signaling sent by the base station, the terminal obtains the target spatial correlation parameter among the multiple spatial correlation parameters to receive the first channel, thereby solving the problem of scheduling a piece of data for each of the multiple DCI signaling, and each piece of data comes from The QCL information in the scenario of different TRP indicates the problem.

Description

technical field [0001] The present application relates to the communication field, and in particular to an information transmission method, device and equipment. Background technique [0002] With the emergence of video services in smart terminals, the current spectrum resources have been difficult to meet the explosive growth of users' demand for capacity. High-frequency frequency bands with larger available bandwidth, such as millimeter wave frequency bands, are increasingly becoming candidate frequency bands for next-generation communication systems. . On the other hand, modern communication systems generally use multi-antenna technology to increase system capacity and coverage, so as to improve user experience. In addition, the use of high-frequency bands can greatly reduce the size of multi-antenna configurations, facilitating site acquisition and deployment of more antennas. However, unlike the working frequency band of the existing Long Term Evolution (LTE) system, ...
