Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/170993
Kind Code:
A1
Abstract:
Provided are a data transmission method and apparatus. The method comprises: receiving a TB from a first terminal device, wherein the TB is used for carrying uplink data of the first terminal device; receiving first scheduling information from a network device, wherein the first scheduling information indicates that a second terminal device initially transmits a portion of the TB; and sending Z code block groups (CBGs) to the network device, wherein the TB comprises M CBGs, the Z CBGs are a portion of the M CBGs, Z is an integer greater than 0 and less than M, and M is an integer greater than 1. In the method, uplink data of a first terminal device can be sent to a network device by means of a second terminal device, and insofar as resources of the first terminal device are not consumed, the transmission rate of the uplink data of the first terminal device can be improved when the transmission rate of the first terminal device is affected by factors such as an uplink bandwidth and an antenna capability, such that the first terminal device can meet the rate requirements of a large uplink capacity.
