In order to more fully understand the technical solutions provided by the embodiments of the present application, the following contents are introduced:

1.1 multiplexing of Rel-15 PUCCH and PUCCH or PUCCH and PUSCH

Uplink Control Information (UCI) is transmitted on the PUCCH. The uplink data is transmitted on the PUSCH. Due to the starting symbol and the symbol length, etc., there may occur an overlap in time between different PUCCHs or between a PUCCH and a PUSCH.

In principle, PUCCH and PUSCH may be transmitted simultaneously, i.e. UCI is reserved in PUCCH. However, this increases the Cubic Metric (Cubic Metric); furthermore, if the requirements for out-of-band transmission are to be met at higher transmit power and the PUSCH and PUCCH are transmitted simultaneously with a large separation in the frequency domain (PUCCH is typically transmitted at both ends of the band), this can present challenges to Radio Frequency (RF) implementations.

Therefore, in a general situation, if there is an overlap between PUCCH resources requiring UCI transmission and time domain resources, or there is an overlap between PUCCH resources requiring UCI transmission and PUSCH resources in time, and the network side can guarantee that a condition of UCI multiplexing processing time is satisfied when scheduling the PUCCH/PUSCH, UCI may be multiplexed on one PUCCH, or UCI and data are multiplexed on PUSCH, avoiding simultaneous transmission of different PUCCHs or simultaneous transmission of PUCCH and PUSCH.

1.1.1 multiplexing between PUCCHs, or UCI multiplexing on the processing Timeline (Timeline) requirement of PUSCH

3GPP Rel-15 defines a multiplexing time line, namely multiplexing between PUCCHs, or multiplexing UCI on PUSCH needs to meet the multiplexing time line condition, and if the scheduling of the network side does not meet the multiplexing time line condition, the scheduling is regarded as wrong scheduling.

1.2 multiplexing and prioritization of uplink transmissions within a UE of NR Rel-16

In order to support different traffic demands, Rel-16 introduces different physical layer priorities and supports the following conflict scenarios, and the behavior of the UE is defined for the following conflict scenarios:

-High Priority (HP) uplink transmission vs High Priority uplink transmission, UE handling in the manner specified by Rel-15

-Low Priority (LP) uplink transmission vs Low Priority uplink transmission, UE handling in the manner specified by Rel-15

-high priority uplink transmission vs low priority uplink transmission, UE performing high priority uplink transmission and cancelling low priority uplink transmission and defining a cancellation timeline; that is, when a certain timeline requirement is met, that is, the timeline condition is cancelled, the UE performs uplink transmission with high priority and cancels uplink transmission with low priority.

1.3 NR Rel-17 PUCCH and PUCCH of different priorities, multiplexing between PUCCH and PUSCH

In order to reduce the impact on low priority transmissions, NR Rel-17 supports multiplexing between uplink transmissions of different priorities and certain multiplexing timeline conditions need to be met.

The following describes in detail an uplink transmission processing method and a terminal provided in the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 is a flowchart illustrating an uplink transmission processing method according to an embodiment of the present application. As shown in fig. 2, an embodiment of the present application provides an uplink transmission processing method, in which a terminal may perform the following operations:

step 210, when the at least two uplink transmission channels meet the multiplexing timeline condition, the terminal transmits the at least two uplink transmission channels in a multiplexing transmission mode;

and step 220, under the condition that the at least two uplink transmission channels meet the condition of canceling the time line, the terminal transmits the at least two uplink transmission channels by adopting a transmission mode of canceling low-priority transmission.

It is understood that the uplink transmission Channel may be PUCCH, PUSCH, and PRACH (Physical Random Access Channel), etc. For example, the at least two uplink transmission channels may be at least two PUCCHs, at least two PUSCHs, at least two PRACH channels, or any number of combinations of PUCCH, PUSCH, and PRACH channels.

In case that at least two uplink transport channels meet the multiplexing timeline condition (as specified in NR Rel-15, NR Rel-16, NR Rel-17), the terminal may transmit the at least two uplink transport channels in a multiplexed transmission manner;

and in case that at least two uplink transport channels meet the cancellation timeline condition (as specified in NR Rel-15, NR Rel-16, NR Rel-17), the terminal may transmit to the at least two uplink transport channels in a transmission mode in which the low priority transmission is cancelled. The transmission mode of canceling the low-priority transmission means that the low-priority uplink transmission channel is not transmitted and only the highest-priority uplink transmission channel is transmitted.

The multiplexing timeline condition may refer to a timeline requirement to be satisfied when multiplexing is performed between different uplink transmission channels when different uplink transmission channels overlap, for example, a time interval from a PDCCH termination to an earliest symbol of an overlapping uplink transmission channel is equal to or greater than a certain value, and/or a time interval from a termination symbol of a PDSCH scheduled by a PDCCH to the earliest symbol of the overlapping uplink transmission channel is equal to or greater than a certain value. Specific contents of the multiplexing timeline condition can refer to NR Rel-15, NR Rel-16, NR Rel-17, etc., and the embodiment of the present application is not limited to this specifically.

The cancellation of the timeline condition may refer to cancellation of transmission of the low-priority uplink transport channel when different uplink transport channels overlap, and only the timeline requirement that needs to be met when the high-priority uplink transport channel is transmitted. For example, the interval from the end symbol of DCI scheduling a high priority channel to the start symbol of a high priority uplink transmission channel is equal to or greater than a certain value. Specific contents of the time line condition can be referred to NR Rel-15, NR Rel-16, NR Rel-17, etc., and the embodiment of the present application is not limited to this.

In the uplink transmission processing method provided by the embodiment of the application, the terminal can simultaneously support the multiplexing transmission mode and cancel the transmission mode of low-priority transmission, so that the uplink transmission performance of the terminal is effectively improved, and the terminal can meet the requirements of various use scenes. In addition, in the uplink transmission processing method provided in the embodiment of the present application, the terminal employs a multiplexing transmission method when a multiplexing timeline condition is satisfied, and employs a transmission method for canceling low-priority transmission when a time line canceling condition is satisfied, so that the processing efficiency and accuracy of uplink transmission performed by the terminal are ensured.

In one embodiment, the terminal may receive higher layer signaling and configure the operation of transmitting the uplink transport channel based on the higher layer signaling. For example, whether the higher layer signaling configuration terminal supports the multiplexed transmission mode between the uplink transmission channels with different priorities, or which operations between the different uplink transmission channels are supported by the higher layer signaling configuration terminal, for example, only the multiplexed transmission mode is supported, only the transmission mode for canceling the low priority transmission is supported, or both the multiplexed transmission mode and the transmission mode for canceling the low priority transmission are supported.

The high layer signaling may refer to various high layer signaling such as RRC (Radio Resource Control) signaling, MAC (Media Access Control), and the like, and the embodiment of the present application does not specifically limit the type of the high layer signaling.

When the terminal configures the operation of transmitting the uplink transport channels based on the higher layer signaling, the step 220 of "at least two uplink transport channels meet the cancellation timeline condition" may include:

the at least two uplink transport channels do not satisfy the multiplexing timeline condition and satisfy the cancellation timeline condition.

That is, under the condition that at least two uplink transport channels do not satisfy the multiplexing timeline condition and satisfy the cancellation timeline condition, the terminal transmits the at least two uplink transport channels by adopting a transmission mode of canceling low-priority transmission.

Optionally, when the terminal configures an operation of transmitting the uplink transport channel based on a higher layer signaling, the operation may further include:

and under the condition that at least two uplink transmission channels do not meet the multiplexing timeline condition and do not meet the cancellation timeline condition, the terminal determines to be an unexpected scene.

It should be noted that, when the multiplexing timeline condition is not satisfied and the cancellation timeline condition is not satisfied, the terminal determines that the application scenario at this time is an undesirable scenario. At this time, the terminal performs other operations according to the protocol, instead of transmitting the uplink transport channel in the multiplexed transport mode or the transport mode in which the low priority transmission is cancelled.

The unexpected scene refers to a scene of wrong scheduling, and the base station should avoid the unexpected scene during scheduling, otherwise, the behavior of the terminal is not defined. Therefore, undesirable scenarios need to be avoided as much as possible.

In a specific example, the terminal may configure the following behavior based on higher layer signaling:

a) behavior 1:

i. under the condition that at least two uplink transmission channels meet the multiplexing timeline condition, the terminal transmits the at least two uplink transmission channels in a multiplexing transmission mode;

in case that the at least two uplink transport channels do not satisfy the multiplexing timeline condition, the terminal determines as an undesired scenario.

b) Behavior 2:

ii, under the condition that the at least two uplink transmission channels do not meet the multiplexing time line condition and meet the time line canceling condition, the terminal transmits the at least two uplink transmission channels by adopting a transmission mode of canceling low-priority transmission;

and iii, under the condition that at least two uplink transmission channels do not meet the multiplexing timeline condition and do not meet the cancellation timeline condition, determining an unexpected scene by the terminal.

Alternatively, the terminal may be enabled to perform multiplexed transmission and cancel transmission of low priority transmissions by higher layer signaling, such as RRC parameters, for example, mulliplexingofullwithdiffferentpriorities { enable, disable }.

When the RRC parameter is disabled, "multiplexing", i.e., configured to "disable", the terminal does not support the multiplexed transport. And when the time domain resources of the uplink transmission channels with different priorities are overlapped, the terminal executes a transmission mode of canceling low-priority transmission.

When the RRC parameter enables "multiplexing", i.e., is configured as "enable", the terminal supports the multiplexed transmission manner. When the time domain resources of the uplink transmission channels with different priorities are overlapped, if at least two uplink transmission channels meet the multiplexing time line condition, the terminal executes the multiplexing transmission mode; if the at least two uplink transmission channels do not meet the multiplexing timeline condition, the terminal determines an unexpected scene; or if the at least two uplink transmission channels do not meet the multiplexing timeline condition and meet the cancellation timeline condition, the terminal executes the transmission mode of canceling the low-priority transmission.

Optionally, the network side may configure the above behavior through a higher layer parameter, that is, whether to support a multiplexing transmission mode, a transmission mode that only supports multiplexing, a transmission mode that only supports canceling low priority transmission, and a transmission mode that supports both multiplexing and canceling low priority transmission. The higher layer parameter may be the same parameter as a parameter configuring whether the terminal supports the multiplexed transmission scheme (e.g., multiplexed with/without multiplexing transmission scheme, parameter 2 configures the multiplexed transmission scheme or cancels the low priority transmission scheme, such as multiplexed with on, multiplexed with, or without), or a different parameter (e.g., parameter 1 enables/disables the multiplexed transmission scheme).

According to the uplink transmission processing method provided by the embodiment of the application, the operation of transmitting the uplink transmission channel by the terminal is configured according to the high-level signaling, so that the processing efficiency and the accuracy of uplink transmission by the terminal can be further ensured.

In one embodiment, the terminal may receive DCI (Downlink Control Information) and perform an operation of transmitting an uplink transport channel based on the DCI.

Wherein, the DCI may include information indicating a multiplexing operation or information indicating a priority operation.

Accordingly, step 210 may include:

under the condition that the DCI indicates multiplexing operation and the at least two uplink transmission channels meet the multiplexing timeline condition, the terminal transmits the at least two uplink transmission channels in a multiplexing transmission mode;

step 220 may include:

and under the condition that the DCI indicates priority operation and the at least two uplink transmission channels meet the condition of canceling the time line, the terminal transmits the at least two uplink transmission channels by adopting a transmission mode of canceling low-priority transmission.

In one embodiment, the operation of the terminal to transmit the uplink transport channel may further include:

under the condition that the DCI indicates multiplexing operation and at least two uplink transmission channels do not meet the multiplexing timeline condition, the terminal determines an unexpected scene; or

And under the condition that the DCI indicates priority operation and at least two uplink transmission channels do not meet the cancel timeline condition, the terminal determines to be an unexpected scene.

For example, the DCI may indicate multiplexing or PRIORITIZATION.

And when the DCI indicates the priority, the terminal does not support the multiplexing among the uplink transmission channels with different priorities. When the time domain resources of the uplink transmission channels with different priorities are overlapped, the terminal transmits the uplink transmission channel by adopting a transmission mode of canceling low-priority transmission.

And when the DCI indicates multiplexing, the terminal supports multiplexing among uplink transmission channels with different priorities. And when the time domain resources of the uplink transmission channels with different priorities are overlapped, the terminal adopts a multiplexing transmission mode to transmit the uplink transmission channels.

In addition, when the multiplexing timeline condition is satisfied, or the multiplexing timeline condition is satisfied and the cancellation timeline condition is satisfied, the network side may indicate multiplexing or priority through DCI.

When the multiplexing timeline condition is not met and the time line cancellation condition is met, the network side can only indicate priority through the DCI, and if the DCI indicates multiplexing, the scene is not expected.

Optionally, when the time line cancellation condition is not satisfied and the time line multiplexing condition is satisfied, the network side may only indicate multiplexing through the DCI, and if the DCI indicates priority, the scenario is an undesirable scenario.

If the multiplexing timeline condition is not satisfied and the canceling timeline condition is not satisfied, then it is an undesirable scenario.

Optionally, in an embodiment, the uplink transmission processing method provided in the embodiment of the present application may further include:

the terminal determines the receiving time for receiving the DCI;

step 210, comprising:

under the condition that the at least two uplink transmission channels meet the multiplexing timeline condition based on the receiving time, the terminal transmits the at least two uplink transmission channels in a multiplexing transmission mode;

step 220, comprising:

and under the condition that the at least two uplink transmission channels are determined to not meet the multiplexing timeline condition and meet the cancellation timeline condition based on the receiving time, the terminal transmits the at least two uplink transmission channels by adopting a transmission mode of canceling low-priority transmission.

It can be appreciated that, when a terminal receives DCI, a reception time at which the DCI is received and/or a transmission time of a channel scheduled by the DCI can be determined. And judging whether the at least two uplink transmission channels at the moment meet the multiplexing timeline condition and/or the cancellation timeline condition or not based on the receiving time.

As shown in FIG. 3, in Case 1, it can be determined from the DCI reception time (PDCCH2) that the uplink transmission channels (PUCCH, PUSCH) satisfy the multiplexing timeline condition (e.g., T) _mux ) And satisfies a cancel timeline condition (T) _cancel ) (ii) a In Case 2, according to the receiving time of the DCIDetermining that the uplink transmission channel does not satisfy a multiplexing timeline condition and satisfies a cancellation timeline condition; in Case 3, it may be determined that the uplink transport channel does not satisfy the multiplexing timeline condition and does not satisfy the cancellation timeline condition according to the reception time of the DCI.

If the terminal determines that the at least two uplink transmission channels meet the multiplexing timeline condition based on the receiving time, the terminal transmits the at least two uplink transmission channels in a multiplexing transmission mode;

and if the terminal determines that the at least two uplink transmission channels do not meet the multiplexing timeline condition and meet the cancellation timeline condition based on the receiving time, the terminal transmits the at least two uplink transmission channels by adopting a transmission mode of canceling low-priority transmission.

And under the condition that at least two uplink transmission channels do not meet the multiplexing timeline condition and do not meet the cancellation timeline condition, the terminal determines an unexpected scene.

Optionally, the network side may configure, through higher layer signaling, the operation of the terminal transmitting the uplink transmission channel according to the indication of the DCI or the reception time when the DCI is received.

According to the uplink transmission processing method provided by the embodiment of the application, the uplink transmission channel is transmitted according to the DCI indication and the time for receiving the DCI, so that the processing efficiency and the accuracy of the uplink transmission performed by the terminal can be further ensured.

In summary, the uplink transmission processing method provided in the embodiment of the present application is particularly suitable for a scenario where time domain resources of uplink transmission channels with different priorities are overlapped, efficiently determines interaction between a multiplexing timeline/cancelling timeline and a multiplexing/cancelling action, and improves effectiveness of a system.
