Problems solved by technology

It may happen that the channel quality of the secondary carrier of the UE is significantly better than that of the main carrier, but the UE still transmits uplink services on the main carrier, which affects the uplink service transmission of the UE and further affects the service experience of the user

Embodiment 1

[0025] refer to figure 1 As shown, it is a schematic diagram of steps of an uplink transmission method for carrier aggregation provided by an embodiment of the present invention. It can be understood that, in the uplink transmission method for carrier aggregation provided by the embodiment of the present invention, the uplink carrier includes a primary carrier and a secondary carrier, UE uplink transmission can be scheduled on the primary carrier and the secondary carrier at the same time, and this is used for carrier aggregation The uplink transmission method is executed on the base station side, which reduces the processing load on the UE side. The uplink transmission method for carrier aggregation includes the following steps:

[0026] Step 10: Obtain the estimated uplink channel quality of the secondary carrier after performing uplink channel quality estimation on the secondary carrier;

[0027] Estimating the channel quality of the auxiliary carrier on the base station ...

Embodiment 2

[0067] see Figure 4 As shown, in an uplink transmission method for carrier aggregation provided by an embodiment of the present invention, the uplink carrier includes a primary carrier and a secondary carrier, and the steps performed on the UE side include:

Abstract

An embodiment of the invention discloses an uplink transmission method and device for carrier aggregation, and a base station. In the uplink transmission method for carrier aggregation, uplink carriers comprise a main carrier and an auxiliary carrier, and the steps executed at a base station side are as follows: estimating the uplink channel quality of the auxiliary carrier to obtain the estimated uplink channel quality of the auxiliary carrier; determining to execute a switching operation based on the estimated quality of the uplink channel of the auxiliary carrier; determining that the auxiliary carrier is an auxiliary carrier to be switched; and triggering UE to execute the switching operation, and switching an original uplink carrier to the auxiliary carrier to be switched for scheduling. The uplink auxiliary carrier of the UE is managed according to the channel quality of the auxiliary carrier, and the uplink service transmission flow of the UE is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to an uplink transmission method, device and base station for carrier aggregation. Background technique [0002] Carrier Aggregation CA (full name in English: Carrier Aggregation) technology can meet the demand for larger bandwidth. Among multiple component carriers serving the UE, there is usually one component carrier as the primary carrier, and the other component carriers are secondary carriers, which are commonly used in LTE networks and NR networks. The UE can perform data transmission on multiple carriers at the same time, thereby increasing the data transmission rate. [0003] With the development of network technology and the emergence of a large number of video services, the demand for UE uplink services is increasing. In the CA technology, the channel quality of the primary carrier, the secondary carrier, and the channel quality of dif...
