Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an uplink transmission processing method and terminal. Background Technology

[0002] When uplink channels of the same priority, such as PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel), overlap in time domain resources, if the multiplexing timeline condition is met, the terminal (User Equipment, UE) can multiplex the information carried by different uplink channels onto one channel for transmission; or when uplink channels of different priorities overlap in time domain resources, if the cancellation timeline condition is met, the UE can cancel the transmission of the low-priority channel and only transmit the high-priority uplink channel.

[0003] In existing technologies, terminals either support multiplexing, in which failure to meet the multiplexing timeline conditions is an undesirable scenario, i.e., an error scenario; or they support canceling low-priority transmission, in which failure to meet the cancellation timeline conditions is an undesirable scenario, i.e., an error scenario.

[0004] Therefore, a method is needed that enables the terminal to simultaneously support multiplexing mode and cancel low-priority transmission mode during uplink transmission. Summary of the Invention

[0006] Firstly, an uplink transmission processing method is provided, applied to a terminal, wherein the terminal performs the following operations in the method:

[0007] When at least two uplink transmission channels meet the multiplexing timeline conditions, the terminal uses a multiplexing transmission method to transmit on at least two uplink transmission channels.

[0008] If at least two uplink transmission channels meet the cancellation timeline condition, the terminal transmits using a transmission method that cancels low-priority transmission on at least two uplink transmission channels.

[0009] The terminal supports multiplexed transmission modes and transmission modes that cancel low-priority transmissions, and the time-domain resources of the at least two uplink transmission channels overlap.

[0010] Secondly, an uplink transmission processing apparatus is provided, the apparatus including a transmission module, the transmission module being configured to perform the following operations:

[0011] If at least two uplink transmission channels meet the multiplexing timeline conditions, the transmission mode of the at least two uplink transmission channels shall be used for transmission.

[0012] If at least two uplink transmission channels meet the cancellation timeline conditions, the transmission method of canceling low-priority transmission is used for transmission on at least two uplink transmission channels.

[0013] The terminal supports multiplexed transmission modes and transmission modes that cancel low-priority transmissions, and the time-domain resources of the at least two uplink transmission channels overlap.

[0014] Thirdly, a communication device is provided, the communication device including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0015] Fourthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0016] Fifthly, a chip is provided, the chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run network-side device programs or instructions to implement the method as described in the first aspect.

[0017] Because the uplink transmission processing method provided in this application embodiment allows the terminal to simultaneously support both multiplexed transmission modes and low-priority transmission cancellation modes, it effectively improves the uplink transmission performance of the terminal, enabling it to meet the needs of various usage scenarios. Furthermore, in the uplink transmission processing method provided in this application embodiment, the terminal employs a multiplexed transmission mode when the multiplexing timeline condition is met, and employs a low-priority transmission cancellation mode when the cancellation timeline condition is met.

[0028] To facilitate a more thorough understanding of the technical solutions provided in the embodiments of this application, the following content is now described:

[0029] 1.1 Rel-15 Multiplexing of PUCCH and PUCCCH or PUCCH and PUSCH

[0030] Uplink Control Information (UCI) is transmitted on the PUCCH. Uplink data is transmitted on the PUSCH. Due to factors such as start symbols and symbol lengths, there may be time overlap between different PUCCHs, or between PUCCHs and PUSCHs.

[0031] In principle, PUCCH and PUSCH can be transmitted simultaneously, with UCI retained in PUCCH. However, this increases the cubic metric; furthermore, if out-of-band transmission requirements are to be met at higher transmit power, and the frequency interval between PUSCH and PUCCH is large when they are transmitted simultaneously (PUCCH is generally transmitted at both ends of the frequency band), this will pose challenges to radio frequency (RF) implementation.

[0032] Therefore, under normal circumstances, if the PUCCHs that need to transmit UCI overlap in time domain resources, or if the PUCCH resources that need to transmit UCI overlap with the PUSCH resources in time, and the network side will ensure that the conditions for UCI multiplexing processing time are met when scheduling the PUCCH / PUSCH, UCI will be multiplexed on one PUCCH, or UCI and data will be multiplexed on the PUSCH, to avoid sending different PUCCHs at the same time or to avoid sending PUCCH and PUSCH at the same time.

[0033] 1.1.1 Timeline requirements for PUCCH multiplexing, or UCI multiplexing within PUSCH processing.

[0034] 3GPP Rel-15 defines the multiplexing timeline, which means that multiplexing between PUCCHs or multiplexing UCI on PUSCHs must meet the multiplexing timeline conditions. If the network-side scheduling does not meet the multiplexing timeline conditions, it is considered an incorrect scheduling.

[0035] 1.2 Multiplexing and Prioritization of Uplink Transmissions within the UE in NR Rel-16

[0036] To support different service requirements, Rel-16 introduces different physical layer priorities and supports the following conflict scenarios, defining UE behavior for these scenarios:

[0037] - High Priority (HP) uplink transmissions vs. high priority uplink transmissions are handled by the UE according to the Rel-15 specification.

[0038] - Low priority (LP) uplink transmissions vs. low priority uplink transmissions are handled by the UE according to the Rel-15 specification.

[0039] - High-priority uplink transmission vs. low-priority uplink transmission: The UE performs high-priority uplink transmission and cancels low-priority uplink transmission, and a cancellation timeline is defined; that is, the UE only performs high-priority uplink transmission and cancels low-priority uplink transmission when certain timeline requirements are met.

[0040] 1.3 NR Rel-17 Multiplexing of PUCCH and PUSCH with different priorities, and between PUCCH and PUSCH

[0041] To reduce the impact on low-priority transmissions, NR Rel-17 supports multiplexing between uplink transmissions of different priorities, and certain multiplexing timeline conditions must be met.

[0042] The uplink transmission processing method and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0043] Figure 2 This is a flowchart illustrating the uplink transmission processing method provided in an embodiment of this application. Figure 2 As shown in the embodiment of this application, an uplink transmission processing method is provided, in which the terminal can perform the following operations:

[0044] Step 210: When at least two uplink transmission channels meet the multiplexing timeline conditions, the terminal transmits using a multiplexed transmission method on at least two uplink transmission channels.

[0045] Step 220: If at least two uplink transmission channels meet the cancellation timeline conditions, the terminal shall transmit on at least two uplink transmission channels using a transmission method that cancels low-priority transmission.

[0046] Among them, the terminal supports multiplexed transmission modes and transmission modes that cancel low-priority transmissions, and the time domain resources of at least two uplink transmission channels overlap.

[0047] It is understandable that uplink transmission channels can be PUCCH, PUSCH, and PRACH (Physical Random Access Channel), etc. For example, at least two uplink transmission channels can be at least two PUCCH, at least two PUSCH, at least two PRACH, or any combination of PUCCH, PUSCH, and PRACH.

[0048] If at least two uplink transmission channels meet the multiplexing timeline conditions (as specified in NR Rel-15, NR Rel-16, and NR Rel-17), the terminal may use a multiplexed transmission method for transmission on the at least two uplink transmission channels.

[0049] If at least two uplink transmission channels meet the cancellation timeline conditions (as specified in NR Rel-15, NR Rel-16, and NR Rel-17), the terminal may transmit using a transmission method that cancels low-priority transmission for these at least two uplink transmission channels. This means that low-priority uplink transmission channels are not transmitted, and only the highest-priority uplink transmission channel is transmitted.

[0050] It should be noted that the multiplexing timeline conditions refer to the timeline requirements that must be met when different uplink transmission channels overlap and are multiplexed. For example, the time interval from the end of the PDCCH to the earliest symbol of the overlapping uplink transmission channel must be greater than or equal to a certain value, and / or the time interval from the end symbol of the PDSCH scheduled by the PDCCH to the earliest symbol of the overlapping uplink transmission channel must be greater than or equal to a certain value. Specific details regarding the multiplexing timeline conditions can be found in NR Rel-15, NR Rel-16, and NR Rel-17, etc., and this application does not impose specific limitations on them.

[0051] The cancellation timeline condition refers to the timeline requirements that must be met when different uplink transmission channels overlap, and the transmission of the lower-priority uplink transmission channel is cancelled, with only the transmission of the higher-priority uplink transmission channel being transmitted. For example, the interval between the end symbol of the DCI of the higher-priority channel and the start symbol of the higher-priority uplink transmission channel must be greater than or equal to a certain value. Specific details regarding the cancellation timeline condition can be found in NR Rel-15, NR Rel-16, and NR Rel-17, etc., and this application does not impose specific limitations on it.

[0052] Because the uplink transmission processing method provided in this application embodiment allows the terminal to simultaneously support both multiplexed transmission modes and low-priority transmission cancellation modes, it effectively improves the uplink transmission performance of the terminal, enabling it to meet the needs of various usage scenarios. Furthermore, in the uplink transmission processing method provided in this application embodiment, the terminal employs a multiplexed transmission mode when the multiplexing timeline condition is met, and employs a low-priority transmission cancellation mode when the cancellation timeline condition is met. Therefore, it ensures the processing efficiency and accuracy of the terminal's uplink transmission.

[0053] In one embodiment, the terminal can receive higher-layer signaling and configure the operation of the uplink transmission channel based on the higher-layer signaling. For example, the higher-layer signaling configures whether the terminal supports multiplexing transmission modes between uplink transmission channels of different priorities, or the higher-layer signaling configures which operations between different uplink transmission channels the terminal supports, such as only supporting multiplexing transmission modes, or only supporting transmission modes that cancel low-priority transmissions, or supporting both multiplexing transmission modes and transmission modes that cancel low-priority transmissions.

[0054] Among them, higher-layer signaling can refer to various higher-layer signaling such as RRC (Radio Resource Control) signaling and MAC (Media Access Control). The embodiments of this application do not specifically limit the type of higher-layer signaling.

[0055] When the terminal configures the operation of the uplink transmission channel based on higher-layer signaling, the "at least two uplink transmission channels satisfy the cancellation timeline condition" in step 220 may include:

[0056] At least two uplink transmission channels do not meet the multiplexing timeline condition but meet the cancellation timeline condition.

[0057] That is, if at least two uplink transmission channels do not meet the multiplexing timeline condition but meet the cancellation timeline condition, the terminal uses the cancellation of low-priority transmission for transmission on at least two uplink transmission channels.

[0058] Optionally, when the terminal configures the operation of the uplink transport channel based on higher-layer signaling, the operation may further include:

[0059] If at least two uplink transmission channels do not meet the multiplexing timeline condition and the cancellation timeline condition, the terminal is determined to be in an undesirable scenario.

[0060] It should be noted that when neither the multiplexing timeline condition nor the cancellation timeline condition is met, the terminal determines that the application scenario is undesirable. In this case, the terminal will perform other operations according to the protocol, instead of using the multiplexing transmission method or the cancellation of low-priority transmission methods to transmit on the uplink transmission channel.

[0061] Undesirable scenarios refer to those involving incorrect scheduling, which base stations should avoid during scheduling; otherwise, the terminal's behavior remains undefined. Therefore, undesirable scenarios should be avoided as much as possible.

[0062] In a specific instance, the terminal can be configured with the following behavior based on higher-level signaling:

[0063] a) Behavior 1:

[0064] i. When at least two uplink transmission channels meet the multiplexing timeline conditions, the terminal uses a multiplexing transmission method to transmit on at least two uplink transmission channels;

[0065] ii. If at least two uplink transmission channels do not meet the multiplexing timeline conditions, the terminal is determined to be in an undesirable scenario.

[0066] b) Behavior 2:

[0067] i. When at least two uplink transmission channels meet the multiplexing timeline conditions, the terminal uses a multiplexing transmission method to transmit on at least two uplink transmission channels;

[0068] ii. If at least two uplink transmission channels do not meet the multiplexing timeline condition but meet the cancellation timeline condition, the terminal shall transmit on at least two uplink transmission channels using a transmission method that cancels low-priority transmission.

[0069] iii. If at least two uplink transmission channels do not meet the multiplexing timeline condition and the cancellation timeline condition, the terminal is determined to be in an undesirable scenario.

[0070] Optionally, higher-level signaling, such as RRC parameters, such as multiplexingOfULwithDifferentPriorities{enable,disable}, can be used to enable the terminal to perform multiplexed transmission modes and disable low-priority transmission modes.

[0071] When the RRC parameter is disabled (i.e., configured as "disable"), the terminal does not support multiplexing transmission modes. Furthermore, when the time-domain resources of uplink transmission channels of different priorities overlap, the terminal executes a transmission mode that cancels the lower-priority transmission.

[0072] When the RRC parameter is enabled (i.e., configured as "enable"), the terminal supports multiplexed transmission modes. Furthermore, when the time-domain resources of uplink transmission channels of different priorities overlap, if at least two uplink transmission channels meet the multiplexing timeline condition, the terminal executes the multiplexing transmission mode; if at least two uplink transmission channels do not meet the multiplexing timeline condition, the terminal determines it as an undesirable scenario; or if at least two uplink transmission channels do not meet the multiplexing timeline condition but meet the cancellation timeline condition, the terminal executes the transmission mode that cancels the low-priority transmission.

[0073] Optionally, the network side can configure the above behavior through higher-level parameters, namely, whether to support multiplexed transmission methods, support only multiplexed transmission methods, support only transmission methods that cancel low-priority transmission, or support both multiplexed and low-priority transmission methods. These higher-level parameters can be the same as the parameter configuring whether the terminal supports multiplexed transmission methods (e.g., multiplexingOfULwithDifferentPriorities{enable, disable}), or different parameters (e.g., parameter 1 enables / disables multiplexed transmission methods, parameter 2 configures multiplexed transmission methods or cancels low-priority transmission methods, such as multiplexingSchemeOfULwithDifferentPriorities{multiplexingOnly, multiplexingOrPrioritization}).

[0074] The uplink transmission processing method provided in this application can further ensure the processing efficiency and accuracy of the terminal's uplink transmission by configuring the operation of the terminal's uplink transmission channel according to higher-layer signaling.

[0075] In one embodiment, the terminal can receive DCI (Downlink Control Information) and perform uplink transmission channel operation based on the DCI.

[0076] The DCI may include information indicating multiplexing operations or information indicating priority operations.

[0077] Accordingly, step 210 may include:

[0078] When DCI indicates multiplexing operation and at least two uplink transmission channels meet the multiplexing timeline conditions, the terminal uses multiplexing transmission mode to transmit on at least two uplink transmission channels.

[0079] Step 220 may include:

[0080] When DCI indicates priority operation and at least two uplink transmission channels meet the cancellation timeline conditions, the terminal transmits at least two uplink transmission channels using a transmission method that cancels low-priority transmission.

[0081] In one embodiment, the operation of the terminal transmitting the uplink transmission channel may further include:

[0082] If the DCI indicates a multiplexing operation and at least two uplink transmission channels do not meet the multiplexing timeline conditions, the terminal is identified as being in an undesirable scenario; or

[0083] If the DCI indicates priority operation and at least two uplink transmission channels do not meet the cancellation timeline conditions, the terminal is determined to be in an undesirable scenario.

[0084] For example, DCI can indicate multiplexing or prioritization.

[0085] When DCI indicates prioritization, the terminal does not support multiplexing uplink transmission channels of different priorities. When the time-domain resources of uplink transmission channels of different priorities overlap, the terminal adopts a transmission method that cancels the transmission of low-priority channels to transmit the uplink transmission channels.

[0086] When DCI indicates multiplexing, the terminal supports multiplexing uplink transmission channels of different priorities. When the time-domain resources of uplink transmission channels of different priorities overlap, the terminal uses multiplexing to transmit the uplink transmission channels.

[0087] In addition, when the multiplexing timeline condition is met, or when both the multiplexing timeline condition and the cancellation timeline condition are met, the network side can indicate multiplexing or prioritization through DCI.

[0088] When the timeline reuse condition is not met, but the timeline cancellation condition is met, the network side can only indicate prioritization through DCI. If DCI indicates multiplexing at this time, it is an undesirable scenario.

[0089] Optionally, when the cancellation timeline condition is not met, but the reuse timeline condition is met, the network side can only indicate multiplexing through DCI. If DCI indicates prioritization at this time, it is an undesirable scenario.

[0090] If neither the timeline reuse condition nor the timeline cancellation condition is met, then it is an undesirable scenario.

[0091] Optionally, in one embodiment, the uplink transmission processing method provided in this application may further include:

[0092] The terminal determines the reception time for the DCI;

[0093] Step 210 includes:

[0094] If, based on the reception time, it is determined that at least two uplink transmission channels meet the multiplexing timeline condition, the terminal uses a multiplexing transmission method to transmit on at least two uplink channels.

[0095] Step 220 includes:

[0096] If, based on the reception time, it is determined that at least two uplink transmission channels do not meet the multiplexing timeline condition but meet the cancellation timeline condition, the terminal shall transmit the data using a transmission method that cancels the low-priority transmission for at least two uplink transmission channels.

[0097] Understandably, when a terminal receives a DCI, it can determine the reception time of the DCI and / or the transmission time of the channel scheduled by the DCI. Based on this reception time, it can then determine whether at least two uplink transmission channels at this time meet the multiplexing timeline condition and / or the cancellation timeline condition.

[0098] like Figure 3 As shown, in Case 1, based on the DCI reception time (PDCCH2), it can be determined that the uplink transmission channels (PUCCH, PUSCH) satisfy the multiplexing timeline conditions (e.g., T). mux And it meets the cancellation timeline condition (T) cancel In Case 2, based on the DCI reception time, it can be determined that the uplink transmission channel does not meet the multiplexing timeline condition, but does meet the cancellation timeline condition; while in Case 3, based on the DCI reception time, it can be determined that the uplink transmission channel does not meet the multiplexing timeline condition, but does not meet the cancellation timeline condition.

[0099] If the terminal determines, based on the reception time, that at least two uplink transmission channels meet the multiplexing timeline condition, then the terminal uses a multiplexing transmission method to transmit on at least two uplink transmission channels.

[0100] If the terminal determines, based on the reception time, that at least two uplink transmission channels do not meet the multiplexing timeline condition, but meet the cancellation timeline condition, then the terminal will use the cancellation low-priority transmission method to transmit on at least two uplink transmission channels.

[0101] Furthermore, if at least two uplink transmission channels do not meet the multiplexing timeline condition and the cancellation timeline condition, the terminal is determined to be in an undesirable scenario.

[0102] Optionally, the network side can configure the aforementioned terminal to transmit uplink transmission channels according to the DCI instruction or the reception time of the received DCI via higher-layer signaling.

[0103] The uplink transmission processing method provided in this application can further ensure the processing efficiency and accuracy of the terminal's uplink transmission by transmitting the uplink transmission channel according to the DCI indication and the time of receiving the DCI.

[0104] In summary, the uplink transmission processing method provided in this application is particularly suitable for scenarios where uplink transmission channels of different priorities overlap in the time domain. It efficiently determines the multiplexing timeline / cancellation timeline and the interaction between multiplexing / cancellation behaviors, thereby improving the effectiveness of the system.

[0105] Figure 4 This is a schematic diagram of the uplink transmission processing apparatus provided in an embodiment of this application. Figure 4 As shown in the figure, this application embodiment provides an uplink transmission processing device, which is applied to a terminal and may include a transmission module 410 for performing the following operations:

[0106] If at least two uplink transmission channels meet the multiplexing timeline conditions, the transmission mode of the at least two uplink transmission channels shall be used for transmission.

[0107] If at least two uplink transmission channels meet the cancellation timeline conditions, the transmission method of canceling low-priority transmission is used for transmission on at least two uplink transmission channels.

[0108] The terminal supports multiplexed transmission modes and transmission modes that cancel low-priority transmissions, and the time-domain resources of the at least two uplink transmission channels overlap.

[0109] Because the uplink transmission processing apparatus provided in this application embodiment supports multiplexed transmission modes and transmission modes that cancel low-priority transmissions, the uplink transmission performance of the terminal is effectively improved, enabling the terminal to meet the needs of various usage scenarios. Furthermore, in the uplink transmission processing apparatus provided in this application embodiment, the terminal uses a multiplexed transmission mode when the multiplexing timeline condition is met, and uses a transmission mode that cancels low-priority transmissions when the cancellation timeline condition is met. Therefore, the processing efficiency and accuracy of the terminal's uplink transmission are guaranteed.

[0111] In one embodiment, the transmission module 410 is further configured to perform the following operations:

[0117] When the DCI indicates multiplexing operation and at least two uplink transmission channels meet the multiplexing timeline conditions, the transmission mode of multiplexing is used for transmission on at least two uplink transmission channels.

[0118] If at least two uplink transmission channels meet the cancellation timeline conditions, transmission shall be performed on at least two uplink transmission channels using a transmission method that cancels low-priority transmissions, including:

[0124] Determine the reception time of the DCI;

[0125] When at least two uplink transmission channels meet the multiplexing timeline conditions, transmission is performed using a multiplexing transmission method on at least two uplink transmission channels, including:

[0126] If, based on the received time, it is determined that at least two uplink transmission channels meet the multiplexing timeline condition, then the at least two uplink transmission channels are transmitted using a multiplexing transmission method.

[0127] If at least two uplink transmission channels meet the cancellation timeline conditions, transmission shall be performed on at least two uplink transmission channels using a transmission method that cancels low-priority transmissions, including:
