The transmission Node may be a Master Node (MN) or a Secondary Node (SN). In addition, in some scenarios, the system may further include a second network side device 13, where the second network side device 13 may be a base station or a transmission node.

Referring to fig. 2, fig. 2 is a flowchart of a carrier configuration method according to an embodiment of the present invention, where the method is used for a user equipment, and as shown in fig. 2, the method includes the following steps:

step 201, receiving a configuration message sent by a first network side device, where the configuration message includes function configuration information of an SUL carrier, the SUL carrier is associated with a downlink carrier of the user terminal, the downlink carrier is also associated with another uplink carrier, and the uplink carrier is a non-SUL carrier;

the SUL carrier may be a low frequency carrier, for example: the frequency resource is a frequency resource of a Long Term Evolution (LTE) system, has a large coverage, and the SUL carrier may be configured to a Primary Cell (PCell), a Primary Cell (PSCell) of a Secondary Cell Group (SCG), or a Secondary Cell (SCell).

The function configuration information of the SUL carrier may be configuration information for configuring the SUL carrier for the user equipment. For example: the indication information of the SUL carrier function, or the configuration information of the SUL carrier, etc. are not limited in this embodiment of the present invention.

After receiving the function configuration information of the SUL carrier, the user terminal may associate the SUL carrier with the downlink carrier, and the downlink carrier is also associated with another uplink carrier, thereby implementing the configuration of the SUL carrier and the uplink carrier that is not the SUL for one downlink carrier, so that the uplink signal corresponding to the downlink carrier may be transmitted through one or two of the two uplink carriers. Of course, the first network side device may associate the SUL carrier with the downlink carrier.

It should be noted that the uplink carrier associated with the downlink carrier may be configured in advance, and the configuration message may configure the SUL carrier only for the downlink carrier, that is, configure the SUL carrier independently.

Step 202, sending a confirmation message of the configuration message to the first network side device.

The confirmation message may be a confirmation message returned to the first network side device after the user terminal successfully receives the configuration message, so as to tell the first network side device that the user terminal has successfully received the configuration message.

The configuration message may be a Radio Resource Control (RRC) configuration message, and the acknowledgement message may be an RRC configuration complete acknowledgement message. Therefore, the SUL carrier configuration for the downlink carrier can be realized in the RRC configuration process. Of course, the configuration message in the embodiment of the present invention is not limited, for example: other configuration messages than RRC configuration messages are also possible.

Through the steps, two uplink carriers can be configured for the downlink carrier of the user terminal so as to enhance the uplink coverage.

step 301, reporting the capability information including the SUL capability indication to the network side.

The reporting to the network side may be actively reported by the user terminal, or reported by the user terminal according to an indication of the network side, or reported when the user terminal attaches to the network, and the like, which is not limited in the embodiment of the present invention.

The SUL capability indication may be used to indicate that the ue has the SUL capability, so that the network side may configure the SUL carrier for the ue.

It should be noted that step 301 may be optional, for example: the user terminal may report the capability information of the user terminal to the network side in advance.

The function configuration information may be configured independently, so that the function configuration information configuring the SUL carrier for the user equipment may not respond to the downlink carrier and the uplink carrier associated with the downlink carrier.

Optionally, the configuration message is determined by the first network side device according to capability information including an SUL capability indication, and step 301 may be reporting the capability information to the first network side device.

In this embodiment, the ue can report the capability information to the first network side device, and the first network side device configures the corresponding configuration message according to the function information of the ue.

The physical channel may be one or more of:

a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Physical Random Access Channel (PRACH), and a Sounding Reference Signal (SRS) Channel.

In addition, the carrier may be identified by identification information of the carrier, for example: the dynamic carrier switching capability indication may include identification information of the carrier, so as to identify that a physical channel of the carrier can be transformed and transmitted according to the network indication information. Wherein the identification information of the carrier may include one or more of the following:

The SUL carrier function indication information may include:

adding the function indication information of the SUL carrier, correcting the function indication information of the SUL carrier or releasing the function indication information of the SUL carrier.

The SUL carrier modification function indication information may indicate that the user terminal modifies the SUL carrier, and the SUL carrier release function indication information may indicate that the user terminal releases the added SUL carrier.

In this embodiment, the accurate configuration of the SUL carriers and the configuration information of the SUL can be realized for the user equipment by the SUL carrier function indication information and the configuration information of the SUL carriers. It should be noted that, since the function configuration information may include one or more items of SUL carrier function indication information and the configuration information of the SUL carrier, in a case that only one item is included, the other item is determined in an implicit manner by the user terminal, for example: only the configuration information of the SUL carrier is configured, it may be implicitly determined to add the SUL carrier, or modify the SUL carrier, for example: only the SUL carrier function indication information is configured, it may be implicitly determined that the cell type is PCell or SCell, etc. And the configuration message may include configuration information of only the SUL carrier, but not configuration information of other carriers, for example: the configuration information of the downlink carrier and the non-SUL uplink carrier associated with the downlink carrier is used for realizing the independent SUL carrier configuration.

The dynamic carrier switching function indication information may be determined according to capability information of the ue, and the dynamic carrier switching function indication information may include: starting or prohibiting the indication of the physical channel dynamic carrier switching function, for example: and starting a PUSCH dynamic carrier switching function indication or forbidding the PUSCH dynamic carrier switching function indication.

The carrier identifier of the SUL carrier and the carrier type identifier of the SUL carrier may be a New identifier (New ID) introduced in this embodiment, and the carrier identifier of the SUL carrier may be used to identify the SUL carrier.

In this embodiment, the identification indication information of the SUL carrier may be identification information of the configured SUL carrier indicated to the user terminal, so that the resource utilization rate and scheduling flexibility are improved when the user terminal performs cross-carrier scheduling or uses two uplink carriers for transmission.

It should be noted that, in this embodiment, various optional embodiments described may be implemented in combination with each other, for example: the configuration information of the SUL carrier may include uplink physical channel configuration information, cell configuration information, and the identifier indication information, and the function configuration information of the SUL carrier further includes the dynamic carrier switching function indication information.

Step 303, sending a confirmation message of the configuration message to the first network side device.
