A data transmission method and user equipment

Abstract

This application provides a data transmission method and user equipment. The method includes: sending, by user equipment UE, auxiliary scheduling information to a first part of or all of network side devices, so that the first part of or all of the network side devices determine an uplink transmission state of the UE according to the auxiliary scheduling information, and perform scheduling on the UE according to the uplink transmission state of the UE, where the uplink transmission state is a first uplink transmission state in which uplink data can be simultaneously transmitted on an uplink carrier corresponding to all of the network side devices, or is a second uplink transmission state in which uplink data can be simultaneously transmitted on an uplink carrier corresponding to a second part of the network side devices; and transmitting, by the UE, data according to scheduling information of the second part of or all of the network side devices.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular to a data transmission method and user equipment. Background technique

[0002] Long Term Evolution-Advanced (LTE-A) is a further evolution and enhanced system of the 3rd Generation Partnership Project (3rd Generation Partnership Project; 3GPP) LTE system. In the LTE-A system, carrier aggregation (CA) technology, also called Spectrum Aggregation technology or Bandwidth Extension technology, is introduced to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology. In carrier aggregation, the frequency spectrum of two or more component carriers (Component Carrier) is aggregated together to obtain a wider transmission bandwidth. The spectrum of each component carrier can be adjacent continuous frequency spectrum or within the same frequency band. Non-adjacent spectrum or even discontinu...
