Problems solved by technology

[0005] However, since the positions of the HPN domains in different DCIs are not necessarily the same, since the position of the HPN domain cannot be determined, the terminal device cannot obtain the information in the HPN domain, and thus cannot determine which configured grant configuration is activated.
Therefore, it may affect the normal transmission of PUSCH

Abstract

The invention provides an uplink dynamic-authorization-free transmission configuration method and a communication device. The method comprises the steps that network equipment generates DCI, wherein the DCI is used for activating or deactivating configured grant configuration; the DCI includes a first indication domain and at least one first class domain; the first indication domain indicates an index of the activated or deactivated configured grant configuration; the number of bits of the first class domain is related to the activated or deactivated configured grant configuration; the first indication domain is located in front of all the first class domains or located at the last position of the DCI; the network equipment sends the DCI to terminal equipment, so that the terminal equipment activates or deactivates the configured grant configuration corresponding to the index based on the DCI. The position of the first indication domain in the DCI is fixed by defining the first indication domain in front of the first class domain or at the last position of the DCI. The terminal equipment may parse the first indication domain based on the fixed location and determine the activated or deactivated configured grant configuration.

Description

technical field [0001] The present application relates to the field of wireless communication, and more specifically, relates to a configuration method and a communication device for uplink dynamic grant-free transmission. Background technique [0002] Uplink dynamic grant-free transmission is widely used in ultra-reliable and low-latency communication (URLLC), enhanced mobile broadband (enhanced Scenarios such as mobile broadband (eMBB) and massive machine type communication (mMTC). [0003] The uplink dynamic grant-free transmission may, for example, transmit uplink data through a configured grant (configured grant) physical uplink shared channel (physical uplink share channel, PUSCH). In an implementation manner, the network device may configure some parameters of the PUSCH for the terminal device through a configured grant configuration (configured grant configuration). Afterwards, the network device may activate or deactivate the configured grant configuration, or per...
