The embodiment of the present disclosure provides a data transmission method, which is applied to a user side device, and can be executed by a user side device. FIG. 1 is a schematic flowchart of a data transmission method according to an embodiment of the present disclosure. Includes the following steps:

Step 102: When there is a conflict between the downlink information transmission resource configured by the RRC and the uplink information transmission resource, one of receiving the downlink information and transmitting the uplink information is performed.

According to the embodiment of the present disclosure, when there is a conflict between the downlink information transmission resource configured by the RRC and the uplink information transmission resource configured by the RRC, one of receiving the downlink information and transmitting the uplink information may be performed, so as to achieve the conflict of the uplink and downlink information transmission resources. The purpose of defining the UE's code of conduct.

The UE may perform one of receiving downlink information and transmitting uplink information when there is a conflict between the downlink information transmission resource configured by the RRC and the uplink information transmission resource configured by the RRC, and thus the UE is compared to the UE due to the resource. If the conflict is abandoned and the downlink information is received and the uplink information is sent, the resource utilization rate can be improved.

In the embodiment of the present disclosure, when there is a conflict between the downlink information transmission resource configured by the RRC and the uplink information transmission resource, the UE may perform one of receiving the downlink information and transmitting the uplink information with a higher priority. For example, the UE may determine to receive the downlink information. The priority of the uplink is higher than the priority of sending the uplink information. The UE receives the downlink information and abandons the uplink information. The UE may determine that the priority of sending the uplink information is higher than the priority of receiving the downlink information. The UE sends the uplink information and discards. Receive downlink information.

In the embodiment of the present disclosure, the downlink information transmission resource and the uplink information transmission resource are all obtained through the RRC configuration, and are all resources whose transmission direction is undetermined.

Specifically, in the TDD system, the network side device may perform semi-static UL/DL configuration on the UE, where the UL/DL configuration indicates a flexible resource, and the transmission direction of the flexible resource is undetermined, in addition to the uplink resource and the downlink resource. . The transmission direction of the flexible resource can be rewritten by signaling such as RRC or Dynamic Slot Format Indicator (dynamic SFI).

For the flexible resource, the network side device can configure the uplink information transmission or the downlink information to be received by the UE on the flexible resource through the RRC. For example, the network side device generates configuration information, and the configuration information is used to configure the uplink information transmission by the UE on the flexible resource through the RRC. Or downlink information reception, such as sending SR, SRS, and information carried by the PRACH, monitoring the PDCCH, detecting the SSB, detecting the CSI-RS, and the like. The network side device sends the configuration information to the UE, and the UE performs uplink information transmission or downlink information reception on the flexible resource according to the configuration information.

The downlink information transmission resource configured by the RRC is in conflict with the uplink information transmission resource, including but not limited to, the network side device configures the uplink information transmission and the configuration downlink on the same flexible resource through the RRC. In the case of information reception, for example, the network side device configures the uplink information transmission and the downlink information reception at the same time by the RRC to the UE.

In one embodiment, the downlink information includes the information carried by the PDCCH, and the uplink information includes the information carried by the PRACH. Correspondingly, in the foregoing step 102, performing one of receiving the downlink information and sending the uplink information, specifically:

If the PRACH is indicated by the PDCCH, the information carried by the PRACH is transmitted.

Specifically, if the PRACH is PDCCH ordered, that is, the UE performs non-contention random access, the UE preferentially transmits the information carried by the PRACH and abandons the monitoring PDCCH. The UE may determine that the priority of sending the uplink information is higher than the priority of receiving the downlink information.

Conversely, if the PRACH is not ordered by the PDCCH, the UE may preferentially monitor the PDCCH and abandon the information carried by the PRACH.

It should be noted that the PDCCH in the "PRACH through PDCCH indication" described herein is not the same PDCCH as the PDCCH monitored by the UE in step 102, and the PDCCH in the "PRACH does not pass the PDCCH indication" described herein, and The PDCCHs monitored by the UE in step 102 are not the same PDCCH.

It can be seen that, in this embodiment, when the network side device configures the PDCCH and the information carried by the PRACH on the same flexible resource through the RRC, the UE can define the behavior criterion of the UE, so that the UE can perform monitoring PDCCH and sending. One of the information carried by PRACH.

Authorized business.

Further, in this embodiment, the monitoring PDCCH is specifically: if there is a common search space (CSS) to be detected at the current time, the PDCCH is monitored.

Specifically, if the UE has a CSS to be detected at the current time, that is, the UE needs to detect the CSS at the current moment, the UE preferentially monitors the PDCCH to receive the information carried by the PDCCH, and abandons the transmission of the SR or the unlicensed service. The UE may determine that the priority of receiving the downlink information is higher than the priority of sending the uplink information.

In contrast, if the UE does not have a CSS to be detected at the current time, that is, the UE does not need to detect the CSS at the current moment, the UE may preferentially send the SR or the unlicensed service, and abandon the monitoring PDCCH.

It can be seen that, in this embodiment, when the network side device configures the PDCCH and configures the sending of the SR or the unlicensed service on the same flexible resource through the RRC, the UE may define the behavior criterion of the UE, so that the UE can perform monitoring of the PDCCH and Send one of the SR or license-free services.

The first specified duration may be in milliseconds (ms) or may be The slot, for example, the first specified duration corresponding to the SR and the first specified duration corresponding to the unlicensed service are both slots.

In the mode (a2), if the transmission period of the SR or the unlicensed service is greater than the corresponding second specified duration, and the monitoring period of the PDCCH is less than the corresponding third specified duration, the UE preferentially sends the SR or the unlicensed service, and abandons the monitoring of the PDCCH. .

Conversely, in mode (a2), if the transmission period of the SR or the unlicensed service is less than or equal to the corresponding second specified duration, or the monitoring period of the PDCCH is greater than or equal to the corresponding third specified duration, the UE preferentially monitors the PDCCH, and Abandon sending SR or license-free business.

In the mode (a2), the second specified duration corresponding to the SR may be the same as the second specified duration corresponding to the unlicensed service, or may be different. The second specified duration may be in milliseconds (ms) or may be The slot, for example, the second specified duration corresponding to the SR and the second specified duration corresponding to the unlicensed service are both slots. The unit of the third specified duration corresponding to the PDCCH may be a millisecond (ms) or a slot. For example, the third specified duration corresponding to the PDCCH is one slot.

Correspondingly, in the foregoing step 102, the receiving the downlink information and the sending the uplink information are performed. One of them is specifically: monitoring the PDCCH.

Specifically, in a case where the network side device configures the PDCCH and the other uplink information to be sent by the RRC to the UE on the same flexible resource, the UE preferentially monitors the PDCCH to receive the information carried by the PDCCH, and abandons the transmission of the uplink information.

Further, in this embodiment, the monitoring PDCCH is specifically: if the CSS to be detected exists at the current time, the PDCCH is monitored.

Specifically, if the UE has a CSS to be detected at the current time, that is, the UE needs to detect the CSS at the current time, the UE preferentially monitors the PDCCH to receive the information carried by the PDCCH, and abandons the transmission of the uplink information.

On the contrary, if the UE does not have a CSS to be detected at the current time, that is, the UE does not need to detect the CSS at the current moment, the UE may preferentially send the uplink information and give up monitoring the PDCCH.

In this embodiment, the uplink information other than the information carried by the PRACH, the SR, and the unlicensed service may be SRS, etc., and the uplink information sent by the UE may be an SRS or the like.

For example, the fifth specified duration corresponding to each other uplink information is 3 slots. The unit of the sixth specified duration corresponding to the PDCCH may be milliseconds (ms) or a slot. For example, the sixth specified duration corresponding to the PDCCH is one slot.

In the mode (b1) and the mode (b2), the value of the fourth specified duration corresponding to the other uplink information, the value of the fifth specified duration corresponding to the other uplink information, and the value of the sixth specified duration corresponding to the PDCCH may be partially or completely the same. They may be different from each other, and the embodiment is not limited.
