Embodiment Construction

[0053] The NR standard has not yet made a specific design for the retransmission scheme in the NCJT scenario. Therefore, in the NCJT scenario, when multiple transmitter devices independently send downlink control information to the receiver device to indicate the HARQ process allocated by itself for the receiver device, the receiver The end device will receive multiple downlink control information, and the HARQ process number indicated by the HARQ process number field in the multiple downlink control information may be repeated, causing the receiving end device to resume transmitting data according to the retransmission data (that is, the transmitting end device sends data) error. For example, the HARQ process number indicated in the downlink control information sent by the transmitter device 1 to the receiver device is the same as the HARQ process number indicated in the downlink control information sent by the transmitter device 2 to the receiver device. When the data is com...

Abstract

The application discloses a data transmission method, a mode indication method, a mode determination method and a device, which belong to the field of mobile communication. The data transmission method includes: receiving at least one piece of transmission control information, the at least one piece of transmission control information includes transmission control information sent by at least one transmitting end device to the receiving end device, and the transmission control information sent by each transmitting end device to the receiving end device contains A retransmission process identifier for performing a retransmission control operation on the data transmission performed by each transmitter device to the receiver device; for each piece of transmission control information in at least one piece of transmission control information, determine the transmission of each piece of transmission control information The end device; based on the retransmission process identifier included in each transmission control information, perform a retransmission control operation on the transmitting end device that sends each transmission control information. The application helps to solve the error-prone problem of the receiving end device in resuming the transmission data, and avoids errors in resuming the transmission data.

Description

technical field [0001] The present application relates to the field of mobile communication, in particular to a data transmission method, a mode indication method, a mode determination method and a device. Background technique [0002] A long term evolution (Long Term Evolution, LTE) or an enhanced long term evolution (Long termevolution-advanced, LTE-A) communication system includes a transmitter device and a receiver device, and control information (such as Downlink control information) transmission and data transmission, and data can be transmitted between the transmitting end device and the receiving end device through a transport block (Transport Block, TB), and the receiving end device usually uses a Hybrid Automatic Repeat reQuest (Hybrid Automatic Repeat reQuest, The HARQ) process (process) processes the TB to perform the HARQ operation. [0003] In the LTE / LTE-A communication system, the transmitting end device can indicate the HARQ process to the receiving end dev...
