Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] In a multi-TRP transmission scenario, the UE can feed back control information such as HARQ, CSI, and scheduling request to the network device through the PUCCH or PUSCH, and the way of feeding back the control information can be joint feedback or independent feedback.

[0036] In the joint feedback mode, the UE sends control information for multiple TRPs in one PUCCH / PUSCH. In the independent feedback mode, the UE separately feeds back the cont...

Abstract

An embodiment of the present invention provides a transmission method, a terminal, a network device, and a computer-readable storage medium. The transmission method can be used in a terminal or a network device, and the transmission method applied to the terminal includes: sending at least one control over a target uplink channel Information; wherein, each of the control information corresponds to TRP identification information of the transmitting and receiving node, and the TRP identification information is used to determine a target TRP corresponding to the control information, and the target TRP is a TRP in a multi-TRP transmission. The embodiment of the present invention can distinguish the control information of each TRP in the multi-TRP transmission technology according to the TRP identification information.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a transmission method, a terminal, a network device and a computer-readable storage medium. Background technique [0002] In order to improve the reliability and effectiveness of transmission, in the Multiple Input Multiple Output (MIMO) technology, a multi-transmission and reception point / multi-antenna panel (multi-TRP / panel) transmission technology is proposed, that is, multiple transceiver nodes (Transmission Reception Point, TRP) can send the same or different data streams to the same user equipment (User Equipment, UE). [0003] In a multi-TRP transmission scenario, UE needs to send control information through Physical Uplink Control Channel (PUCCH) or Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH). These control information include Hybrid Automatic Repeat Request (Hybird Automatic RepeatQuest, HARQ) information and channel state information...
