Title:
DATA TRANSMISSION METHOD AND APPARATUS AND USER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/134098
Kind Code:
A1
Abstract:
The present disclosure relates to a data transmission method and apparatus and a user device. The method comprises: receiving a transmission direction of a time domain symbol indicated by a base station using indication information of a slotted mode by means of a group universal physical downlink control channel; determining, on the basis of the transmission direction of the time domain symbol, transmission time-frequency resources where a transmission direction collision occurs, the transmission time-frequency resources being time-frequency resources in an uplink scheduling-free resource period allocated by the base station; when the number of the transmission time-frequency resources where a transmission direction collision occurs is less than a preset value, determining available time-frequency resources in the resource period capable of transmitting uplink data; and transmitting uplink data on the available time-frequency resources. The technical solution of the present disclosure allows the user device to make a reasonable data transmission decision for the number and position of the colliding time-frequency resources in GF resource period, so as to achieve the reliability and delay equalization of data transmission in the GF resource period.
