Embodiment 1

[0089] This embodiment provides a data transmission method, please refer to figure 2 As shown, it is a flow chart of the method for data transmission in this embodiment, and the method includes:

[0090] Step 101: The user equipment UE sends auxiliary scheduling information to the first part or all of the network-side devices, instructing the first part or all of the network-side devices to determine the uplink transmission status of the UE according to the auxiliary scheduling information, and determine the triggering of the UE according to the uplink transmission status of the UE. The network-side devices for the UE to transmit data are all network-side devices or the second part of network-side devices;

[0091] Step 102: the UE transmits data according to the scheduling information sent by the second part or all of the network side devices.

[0092] Wherein, in this embodiment, the uplink transmission status is the first uplink transmission status in which uplink data ca...

Embodiment 2

[0165] An embodiment of the present application also provides a user equipment, please refer to Figure 5 As shown, the user equipment includes: a first sending unit 401, configured to send auxiliary scheduling information to the first part or all of the network-side devices, instructing the first part or all of the network-side devices to determine the uplink transmission of the user equipment UE according to the auxiliary scheduling information. According to the UE's uplink transmission status, it is determined that the network-side devices that can trigger the UE to transmit data are all network-side devices or the second part of the network-side devices, where the uplink transmission status can be corresponding to all network-side devices at the same time The first uplink transmission state of transmitting uplink data on the uplink carrier, or the second uplink transmission state of transmitting uplink data on the uplink carrier corresponding to the network side equipment o...

Embodiment 3

[0175]This embodiment provides a user equipment, please refer to Figure 6 Shown is a conceptual diagram of an example of hardware implementation of the user equipment, the user equipment includes: a transmitter 504, configured to send auxiliary scheduling information to the first part or all of the network side devices, indicating that the first part or all of the network side devices according to the auxiliary scheduling information The scheduling information determines the uplink transmission state of the user equipment UE, and according to the uplink transmission state of the UE, it is determined that the network-side devices that can trigger the UE to transmit data are all network-side devices or the second part of the network-side devices, where the uplink transmission state is capable of Simultaneously transmit the first uplink transmission state of uplink data on the uplink carrier corresponding to all network side devices, or simultaneously transmit the second uplink t...

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...
