Embodiment 1

[0088] see figure 1 and figure 2 as shown, figure 1 and figure 2 The information transmission method provided by Embodiment 1 of the present disclosure. The information transmission method in this embodiment can be applied to a terminal, and can also be applied to a TRP (such as a base station). in:

[0089] figure 1 The information transfer methods shown include:

[0090] S101: Determine N active bandwidth parts;

[0091] It should be understood that, in this embodiment, the terminal and / or the TRP may select N bandwidths that meet predetermined requirements from all BWPs (Bandwidth part, bandwidth part) for activation, so as to determine N BWPs in the activated state. Or the terminal and / or the TRP agree that the N bandwidth parts that are in an active state need to meet the agreed requirements.

[0092] S102: Transmit channels and / or signals on the activated N bandwidth parts.

[0093] It should be understood that the channel transmitted in this embodiment essent...

Embodiment 2

[0358] In this embodiment, in order to realize multi-TRP transmission, increase system spectrum efficiency, and / or improve communication robustness. A terminal can simultaneously receive data transmissions from multiple TRPs at the same time, such as image 3 As shown, the terminal can simultaneously receive PDSCH (Physical Downlink Shared Channel) 1 and PDSCH2 in the same slot, where PDSCH1 is sent by TRP1, and PDSCH2 is sent by TRP2. There is no ideal Backhaul between the two TRPs, so PDSCH1 is scheduled by DCI1, and PDSCH2 is scheduled by DCI2. Since the resources occupied by PDSCH1 and PDSCH2 may overlap, and if the channel and / or signal parameter configurations of the two TRP transmissions are allowed to be different, it can be realized through the following scheme.

[0359] In one time unit, one terminal is configured with N active BWPs in one CC, and the configuration information of each BWP is configured with channel and / or signal parameter information in the BWP. Su...

Embodiment 3

[0396] In the second embodiment, there are N BWPs in the active state in the same time period in a CC. While supporting the independent configuration parameters of the BWP corresponding to each TRP, it is necessary to limit the N BWPs as far as possible, so that the terminal side It can be connected based on a larger BWP that can include the N BWPs to reduce terminal power consumption.

[0397] In this embodiment, it is described from another angle. N BWPs that are active in the same period of time in a CC need frequency division, such as Figure 14 As shown, there is no ideal Backhaul between the two TRPs. In order to reduce the interference between the two TRPs, the BWPs corresponding to the two TRPs can be frequency-divided, thereby increasing robustness and reducing power consumption. Each panel on the terminal side only handles relatively small bandwidth, such as Figure 14 As shown, the terminal panel1 only handles the BWP1 bandwidth, and the terminal panel2 only handl...

Abstract

The invention provides an information transmission method, an information monitoring method, a device, a base station, a terminal and a storage medium. The method comprises the following steps: determining N bandwidth parts in an activated state; transmitting a channel and / or a signal over the activated N bandwidth portions; and / or determining D control channel resource groups, monitoring the control information in the D control channel resource groups, and transmitting the channel and / or the signal according to the monitored control information. In this way, when each TRP and / or terminal performs information transmission in this way, multiple TRPs can be effectively supported to provide effective service for one terminal under a beam mechanism.

Description

technical field [0001] The present disclosure relates to but not limited to the technical field of communication, and specifically, relates to but not limited to an information transmission method, a monitoring method, a device, a base station, a terminal and a storage medium. Background technique [0002] As the core technology of communication, MIMO (Multiple input multiple output) technology can greatly improve spectrum utilization. One of the core technologies of NR is beam-based communication. Beam communication can reduce interference and enhance coverage, but because it is not fully covered, robustness is a problem. [0003] When multiple TRPs (Transmission and Reception Points, transmitting and receiving points) are used to serve a terminal, since multiple TRPs often have a certain distance in physical location, the diversity of paths to the terminal is guaranteed, which can effectively Improving spectral efficiency can also greatly improve the robustness of communi...
