Embodiment Construction

[0074] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0075] The present invention aims at the problem that PUSCH transmission on semi-static Flexible symbols cannot be realized in the existing technology, and provides a transmission method of uplink shared channel PUSCH, which is applied to terminals, such as figure 1 shown, including:

[0076] Step 11: If the terminal is configured to monitor the downlink control information DCI, then obtain the time interval between the time when the receiving of the DCI is completed and the time when the transmission of the PUSCH starts; wherein, the DCI includes a slot format index SFI-index field;

[0077] Step 12: When the time interval satisfies the preset condition, according to the SFI-index field in the DCI, determine whether the symbol indicated by the radio res...

Abstract

The invention provides an uplink shared channel (PUSCH) transmission method and device, and a terminal, and the method comprises the steps: obtaining a time interval between the receiving completion time of DCI and the transmission start time of a PUSCH if the terminal is configured to monitor the DCI; wherein the DCI comprises an SFI-index domain; and when the time interval meets a preset condition, determining whether the symbol indicated as the semi-static Flexible by the RRC signaling can be used for PUSCH transmission or not according to the SFI-index domain in the DCI. According to the scheme, the problem that transmission of the PUSCH on the semi-static Flexible symbol cannot be realized in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a transmission method, device and terminal of an uplink shared channel PUSCH. Background technique [0002] Currently, in the 5G NR (new air interface) frame structure, the subframe symbol transmission direction can be configured by the semi-static RRC (radio resource control) and the SFI (slot format indication)-index (index) field in the DCI (downlink control information) format 2_0 Indicates a common decision, the RRC semi-static configuration is "Uplink (uplink)" symbols cannot be used for downlink transmission, the RRC semi-static configuration is "Downlink (downlink)" symbols cannot be used for uplink transmission, RRC semi-static configuration is "Flexible ( flexible)" may be used for upstream or downstream or without any transmission. [0003] When the UE is configured to detect SFI, the symbol configured semi-statically as "Flexible" may be further indicated a...
