[0030] The present application is described below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features within the embodiments of the present application may be combined with each other in any manner. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present application, not all structures.

[0031] In the fifth-generation mobile communication technology NR, the UE can support different types of service transmission. However, considering the complexity of UE implementation, only one uplink channel is allowed to be transmitted within a certain period of time. When two uplink channels overlap in time domain, the UE can only choose to transmit one of them, and the other one is canceled. Currently, there is a lack of effective mechanisms to clearly handle the transmission of two uplink transmissions with time domain overlap, such as how to reuse the canceled resources and how to determine the start position of the cancellation. This results in poor flexibility and low reliability of uplink transmission scheduling.

[0032] In an embodiment of the present application, an uplink transmission method is provided. When two uplink transmission time domains overlap, the uplink transmission of the first priority is canceled, and the canceled time domain symbols can be reused for the third uplink transmission, thereby improving resource utilization and scheduling flexibility, and further improving the reliability of the uplink transmission.

[0033] Figure 1 A flowchart of an uplink transmission method provided in an embodiment is shown in FIG. Figure 1 As shown, the method provided in this embodiment includes step 110 and step 120.

[0034] In step 110, when a first uplink transmission overlaps with a second uplink transmission in time domain, the transmission of part or all of the time domain symbols in the first uplink transmission is canceled, wherein the first uplink transmission corresponds to a first priority, the second uplink transmission corresponds to a second priority, and the first priority is lower than the second priority.

[0035] In step 120, if a set condition is met, a third uplink transmission is transmitted using the time domain symbols whose transmission was canceled in the first uplink transmission.

[0036] Figure 2 FIG. 1 is a schematic diagram of uplink transmission time domain overlap provided by an embodiment. Figure 2 As shown, when a first uplink transmission (low priority) overlaps with a second uplink transmission (high priority) in the time domain, the time domain symbols of the first uplink transmission are completely or partially canceled. If set conditions are met, the canceled time domain symbols that do not overlap with the first uplink transmission are allowed to be used to transmit the third uplink transmission. By reusing the canceled but non-overlapping time domain symbol resources of the first uplink transmission, resource waste is avoided and the reliability of the uplink transmission is improved.

[0037] In one embodiment, the third uplink transmission corresponds to the first priority, and the scheduling type of the third uplink transmission is semi-static scheduling; the setting conditions include: the set time length before the start symbol of the third uplink transmission is later than the start symbol or the end symbol of the downlink control information (Downlink Control Information, DCI) corresponding to the second uplink transmission.

[0038] In this embodiment, the third uplink transmission is the first priority uplink transmission of semi-persistent scheduling. Semi-persistent scheduling means that the third uplink transmission does not need to be scheduled by the DCI for uplink transmission scheduling. When the third uplink transmission meets the first time line, the cancelled time domain symbols can be used to transmit the third uplink transmission. Figure 2 As shown, the first timeline refers to: starting from the starting symbol (starting point) of the third uplink transmission and moving forward for a set time length, later than the starting symbol (starting point) or the last symbol (end point) of the DCI corresponding to the second uplink transmission. In some embodiments, the first timeline may also refer to starting from the starting symbol (starting point) of the third uplink transmission and moving forward for a set time length, no earlier than the starting symbol (starting point) or the last symbol (end point) of the DCI corresponding to the second uplink transmission. The set time length may be T defined by 38.214. proc,2 、T proc,1 Or other predefined values, such as N1, N2 or N3 defined in 38.214, may also be related to the capabilities reported by the UE.

[0039] In this embodiment, the first uplink transmission includes: a physical uplink control channel (PUCCH) for transmitting a first-priority hybrid automatic repeat request acknowledgment information (HARQ-ACK), a PUCCH for transmitting a first-priority scheduling request (SR), a PUCCH for transmitting a first-priority periodic channel state information (P-CSI), a physical uplink shared channel (PUSCH) for transmitting a first-priority channel state information (CSI), a PUCCH for transmitting a first-priority beam failure recovery (BFR), a PUSCH for transmitting a first-priority dynamically scheduled uplink data, or a PUSCH for transmitting a first-priority semi-statically scheduled uplink data. In some embodiments, the first uplink transmission may also be a first-priority sounding reference signal (SRS) or a first-priority aperiodic channel state information (A-CSI). StateInformation, A-CSI) PUCCH.

[0040] The set duration is determined according to the type of the second uplink transmission or the third uplink transmission.

[0041] In one embodiment, the second uplink transmission includes: PUCCH for transmitting HARQ-ACK of the second priority, PUCCH for transmitting SR of the second priority, PUSCH for transmitting CSI of the second priority, PUCCH for transmitting BFR of the second priority, PUSCH for transmitting dynamically scheduled uplink data of the second priority, or PUSCH for transmitting semi-statically scheduled uplink data of the second priority. In some embodiments, the second uplink transmission may also be PUCCH for transmitting non-periodic channel state information of the second priority. The type of the second uplink transmission is different, and the corresponding set duration may also be different.

[0042] In one embodiment, the third uplink transmission includes: a physical uplink control channel PUCCH for transmitting HARQ-ACK of the first priority, a PUCCH for transmitting SR of the first priority, a PUCCH for transmitting P-CSI of the first priority, a PUSCH for transmitting CSI of the first priority, a PUCCH for transmitting BFR of the first priority, a PUSCH for transmitting dynamically scheduled uplink data of the first priority, or a PUSCH for transmitting semi-statically scheduled uplink data of the first priority. In some embodiments, the third uplink transmission may also be SRS of the first priority or PUCCH for transmitting A-CSI of the first priority. The type of the third uplink transmission is different, and the corresponding set duration may also be different.

[0043] In this embodiment, after the DCI corresponding to the second uplink transmission (high priority) is received, the UE can obtain the starting position of the time domain symbol of the canceled first uplink transmission (low priority). On this basis, there is no need to detect the time line of the third uplink transmission and the second uplink transmission together, and there is sufficient time to prepare for the transmission of the third uplink transmission. Therefore, the third uplink transmission is transmitted through the canceled non-overlapping time domain symbols.

[0044] In one embodiment, the third uplink transmission corresponds to the first priority, and the scheduling type of the third uplink transmission is dynamic scheduling; the setting conditions include: the starting symbol of the third uplink transmission is later than the set time length after the end symbol of the DCI corresponding to the third uplink transmission; the starting symbol of the DCI corresponding to the third uplink transmission is later than the starting symbol of the DCI corresponding to the second uplink transmission, or, the end symbol of the DCI corresponding to the third uplink transmission is later than the end symbol of the DCI corresponding to the second uplink transmission.

[0045] Figure 3 This is a schematic diagram of uplink transmission time domain overlap provided by another embodiment. Figure 3 As shown, in the case where the time domains of the first uplink transmission (low priority) and the second uplink transmission (high priority) overlap, the time domain symbols of the first uplink transmission are completely or partially canceled. When the set conditions are met, among the canceled time domain symbols, the time domain symbols that do not overlap with the time domain of the first uplink transmission are allowed to be used to transmit the third uplink transmission.

[0046] In this embodiment, the third uplink transmission is a first-priority uplink transmission that is dynamically scheduled. Dynamic scheduling means that the third uplink transmission needs to be scheduled by the DCI used for uplink transmission scheduling. When the third uplink transmission meets the second timeline, the canceled time domain symbols can be used to transmit the third uplink transmission. Figure 3As shown, the second timeline refers to: the starting symbol (starting point) of the third uplink transmission is later than the set time length after the end symbol (end point) of the DCI corresponding to the third uplink transmission; the starting symbol (starting point) of the DCI corresponding to the third uplink transmission is later than the starting symbol (starting point) of the DCI corresponding to the second uplink transmission, or the end symbol (end point) of the DCI corresponding to the third uplink transmission is later than the end symbol (end point) of the DCI corresponding to the second uplink transmission. In some embodiments, the second timeline may also refer to: the starting symbol (starting point) of the third uplink transmission is not earlier than the set time length after the end symbol (end point) of the DCI corresponding to the third uplink transmission; the starting symbol (starting point) of the DCI corresponding to the third uplink transmission is not earlier than the starting symbol (starting point) of the DCI corresponding to the second uplink transmission, or the end symbol (end point) of the DCI corresponding to the third uplink transmission is not earlier than the end symbol (end point) of the DCI corresponding to the second uplink transmission. The set time length can be T defined by 38.214. proc,2 、T proc,1 Or other predefined values, such as N1, N2 or N3 defined in 38.214, may also be related to the capabilities reported by the UE.

[0047] In this embodiment, the set duration is determined according to the type of the second uplink transmission or the third uplink transmission. Different types of second uplink transmission may have different corresponding set durations; different types of third uplink transmission may have different corresponding set durations.

[0048] In this embodiment, the start symbol (or end symbol) of the DCI corresponding to the third uplink transmission is later than or no earlier than the start symbol (or end symbol) of the DCI corresponding to the second uplink transmission. On this basis, the UE can know that the transmission of the first uplink transmission is canceled starting from a certain time domain symbol, and there is no need to detect the time line of the third uplink transmission and the second uplink transmission together; and after the set time length after the DCI corresponding to the third uplink transmission, the third uplink transmission is scheduled, and there is sufficient time to prepare for the transmission of the third uplink transmission. Therefore, the third uplink transmission is transmitted through the canceled non-overlapping time domain symbols.

[0049] In one embodiment, the setting condition also includes: the starting symbol of the DCI corresponding to the second uplink transmission is later than the starting symbol of the DCI corresponding to the first uplink transmission, or the ending symbol of the DCI corresponding to the second uplink transmission is later than the ending symbol of the DCI corresponding to the first uplink transmission.

[0050] In this embodiment, the start symbol (or end symbol) of the DCI corresponding to the second uplink transmission is later than the start symbol (or end symbol) of the DCI corresponding to the first uplink transmission, thereby ensuring that in the case of time domain overlap, the transmission of all or part of the time domain symbols of the first uplink transmission is canceled. In this embodiment, the start symbol refers to the starting point of the start symbol, and the end symbol refers to the ending point of the end symbol. In some embodiments, the setting condition also includes: the start symbol (or end symbol) of the DCI corresponding to the second uplink transmission is not earlier than the start symbol (or end symbol) of the DCI corresponding to the first uplink transmission.

[0051] In one embodiment, the third uplink transmission corresponds to the second priority, and the scheduling type of the third uplink transmission is semi-static scheduling; the setting conditions include: the set time length before the start symbol of the third uplink transmission is later than the start symbol or end symbol of the DCI corresponding to the second uplink transmission.

Figure 4 As shown, in the case where the time domains of the first uplink transmission (low priority) and the second uplink transmission (high priority) overlap, the time domain symbols of the first uplink transmission are completely or partially canceled. When the set conditions are met, among the canceled time domain symbols, the time domain symbols that do not overlap with the time domain of the first uplink transmission are allowed to be used to transmit the third uplink transmission.

[0053] In this embodiment, the third uplink transmission is the first priority uplink transmission of semi-persistent scheduling. When the third uplink transmission meets the third timeline, the cancelled time domain symbols can be used to transmit the third uplink transmission. Figure 4 As shown, the third timeline means that the set time length before the start symbol (starting point) of the third uplink transmission is later than the start symbol (starting point) or the end symbol (end point) of the DCI corresponding to the second uplink transmission. In some embodiments, the third timeline may mean that the set time length before the start symbol (starting point) of the third uplink transmission is not earlier than the start symbol (starting point) or the end symbol (end point) of the DCI corresponding to the second uplink transmission. The set time length may be T defined as 38.214 proc,2 、T proc,1 Or other predefined values, such as N1, N2 or N3 defined in 38.214, may also be related to the capabilities reported by the UE.

[0054] In this embodiment, the set duration is determined according to the types of the second uplink transmission and the third uplink transmission. Different types of second uplink transmission may have different corresponding set durations; different types of third uplink transmission may have different corresponding set durations.

[0055] In this embodiment, the set time length before the start position of the third uplink transmission is later than the end symbol of the DCI corresponding to the second uplink transmission, and there is sufficient time length to prepare for transmitting the third uplink transmission. Therefore, the third uplink transmission is transmitted through the canceled non-overlapping time domain symbols.

[0056] In one embodiment, the third uplink transmission corresponds to the second priority, and the scheduling type of the third uplink transmission is dynamic scheduling. The setting conditions include: a start symbol of the third uplink transmission is later than a set time length after the end symbol of the DCI corresponding to the third uplink transmission; a start symbol of the DCI corresponding to the third uplink transmission is later than a start symbol of the DCI corresponding to the second uplink transmission, or an end symbol of the DCI corresponding to the third uplink transmission is later than an end symbol of the DCI corresponding to the second uplink transmission; and the third uplink transmission and the second uplink transmission do not overlap in time domain.

Figure 5 As shown, in the case where the time domains of the first uplink transmission (low priority) and the second uplink transmission (high priority) overlap, the time domain symbols of the first uplink transmission are completely or partially canceled. When the set conditions are met, among the canceled time domain symbols, the time domain symbols that do not overlap with the time domain of the first uplink transmission are allowed to be used to transmit the third uplink transmission.

[0058] In this embodiment, the third uplink transmission is the first priority uplink transmission of semi-persistent scheduling. When the third uplink transmission meets the fourth timeline, the cancelled time domain symbols can be used to transmit the third uplink transmission. Figure 5 As shown, the fourth timeline refers to: the starting symbol (starting point) of the third uplink transmission is later than the set time length after the end symbol (end point) of the DCI corresponding to the second uplink transmission; the starting symbol (starting point) of the DCI corresponding to the third uplink transmission is later than the starting symbol (starting point) of the DCI corresponding to the second uplink transmission, or, the end symbol (end point) of the DCI corresponding to the third uplink transmission is later than the end symbol (end point) of the DCI corresponding to the second uplink transmission. In some embodiments, the fourth timeline may refer to: the starting symbol (starting point) of the third uplink transmission is not earlier than the set time length after the end symbol (end point) of the DCI corresponding to the second uplink transmission; the starting symbol (starting point) of the DCI corresponding to the third uplink transmission is not earlier than the starting symbol (starting point) of the DCI corresponding to the second uplink transmission, or, the end symbol (end point) of the DCI corresponding to the third uplink transmission is not earlier than the end symbol (end point) of the DCI corresponding to the second uplink transmission. The set time length may be T defined as 38.214. proc,2 、T proc,1Or other predefined values, such as N1, N2 or N3 defined in 38.214, may also be related to the capabilities reported by the UE.

The start symbol (or end symbol) of the DCI corresponding to the third uplink transmission is later than the start symbol (or end symbol) of the DCI corresponding to the second uplink transmission. The time domains of the third uplink transmission and the second uplink transmission do not overlap, so there is sufficient time to prepare for transmission of the third uplink transmission, avoiding reverse order transmission, and ensuring that the order in which the third uplink transmission and the second uplink transmission are scheduled by DCI is consistent with the order of transmission opportunities.

[0061] In one embodiment, the setting condition also includes: the starting symbol of the DCI corresponding to the second uplink transmission is later than the starting symbol of the DCI corresponding to the first uplink transmission, or the ending symbol of the DCI corresponding to the second uplink transmission is later than the ending symbol of the DCI corresponding to the first uplink transmission.

[0062] In this embodiment, the start symbol (or end symbol) of the DCI corresponding to the second uplink transmission is later than the start symbol (or end symbol) of the DCI corresponding to the first uplink transmission, thereby ensuring that in the case of time domain overlap, the transmission of all or part of the time domain symbols of the first uplink transmission is canceled. In this embodiment, the start symbol refers to the starting point of the start symbol, and the end symbol refers to the ending point of the end symbol. In some embodiments, the setting condition may also include: the start symbol of the DCI corresponding to the second uplink transmission is not earlier than the start symbol of the DCI corresponding to the first uplink transmission, or the end symbol of the DCI corresponding to the second uplink transmission is not earlier than the end symbol of the DCI corresponding to the first uplink transmission.

[0078] In one embodiment, the setting condition includes: the third uplink transmission corresponds to the second priority.

[0079] In this embodiment, whether the non-overlapping time domain symbols that were canceled in the first uplink transmission can be reused is determined based on the priority of the service. For example, the service node (e.g., base station) and the communication node (e.g., UE) agree that for the same UE, when the time domain resources of multiple uplink transmission channels overlap, in the canceled uplink transmission of the first priority, the non-overlapping time domain symbols are allowed to be used to transmit the third uplink transmission of the second priority, or are prohibited from being used to transmit the third uplink transmission of the first priority, thereby ensuring that the third uplink transmission of the second priority will not be delayed and ensuring the reliability of the second priority service.

[0080] The uplink transmission method of the above embodiment improves resource utilization and the efficiency of uplink transmission by reusing the time domain symbols of the canceled uplink transmission, provides an effective solution for uplink transmission and uplink transmission multiplexing in the case of time domain overlap, and improves the flexibility and reliability of scheduling and transmission.

[0081] In an embodiment of the present application, an uplink transmission method is also provided. In the case of time domain overlap of uplink transmission, the start symbol of the canceled uplink transmission is clearly defined, providing an effective solution for uplink transmission in the case of time domain overlap, improving the flexibility and reliability of uplink transmission, and enabling the base station to accurately receive the actual transmission part, thereby improving the efficiency of uplink transmission.

[0082] Figure 6 A flowchart of an uplink transmission method provided in another embodiment is shown in FIG. Figure 6 As shown, the method provided in this embodiment includes step 210 and step 220.

[0083] In step 210, when a first uplink transmission overlaps with a second uplink transmission in time domain, a start symbol at which the first uplink transmission is canceled is determined, wherein the first uplink transmission corresponds to a first priority, the second uplink transmission corresponds to a second priority, and the first priority is lower than the second priority.

[0084] In step 220, transmission of part or all of the time domain symbols in the first uplink transmission is canceled according to the start symbol.

[0085] In this embodiment, when the time domains of the first uplink transmission (first priority) and the second uplink transmission (second priority) overlap, the start symbol of the first uplink transmission of the first priority whose transmission is canceled is first identified, and based on this, the transmission of part or all of the time domain symbols in the first uplink transmission is canceled to ensure the reliability of the uplink transmission of the second priority.

[0086] In one embodiment, the start symbol of the first uplink transmission whose transmission is canceled may refer to the latest symbol allowed for the first uplink transmission, i.e., the start symbol is allowed to be transmitted, and the time domain symbols after the start symbol are canceled; or it may refer to the first symbol whose transmission is canceled, i.e., the start symbol and the time domain symbols after the start symbol are all canceled. If it is agreed that the start symbol is included in the symbols whose transmission is canceled, then all time domain symbols starting from the start symbol are canceled; if it is agreed that the symbol is not included in the symbols whose transmission is canceled, then the start symbol is allowed to be transmitted. The start symbol is a boundary symbol, and its processing method can be pre-agreed by the communication node or by the protocol.

[0087] In one embodiment, the start symbol of the first uplink transmission that is canceled may be the latest symbol to which the first uplink transmission is allowed to be transmitted, after which the first uplink transmission cannot be transmitted any further, that is, if the first uplink transmission is not completed, the remaining transmission needs to be canceled. Alternatively, the start symbol of the first uplink transmission that is canceled may also be the start symbol to which the first uplink transmission must be transmitted (if the end position of the first uplink transmission is later than the start symbol). Note: The start symbol is a boundary symbol, and its processing method may be pre-agreed by the communication node or by the protocol. For example, if it is agreed that the symbol is included in the canceled symbols, the cancellation starts from this symbol. If it is agreed that the symbol is not included in the canceled symbols, the symbol is allowed to be transmitted, and the symbol after this symbol is the canceled symbol.

[0088] In one embodiment, the second uplink transmission includes multiple dynamically scheduled second-priority uplink transmissions; the multiple dynamically scheduled second-priority uplink transmissions do not overlap in time domain; the multiple dynamically scheduled second-priority uplink transmissions all overlap in time domain with the first uplink transmission; determining the starting symbol of the first uplink transmission being canceled includes: determining the starting symbol of the first uplink transmission being canceled based on the multiple dynamically scheduled second-priority uplink transmissions.

[0089] In this embodiment, the second uplink transmission includes multiple dynamically scheduled uplink transmissions of the second priority, for example, uplink transmission 1, uplink transmission 2 and uplink transmission 3. The time domains of these three uplink transmissions do not overlap, but they all overlap with the time domain of the first uplink transmission, and there is a conflict in the uplink transmission. In this case, the start symbol of the canceled transmission of the first uplink transmission is determined based on uplink transmission 1, uplink transmission 2 and uplink transmission 3.

[0090] In one embodiment, the start symbol satisfies: starting from a set duration after the last symbol of the DCI corresponding to the first dynamically scheduled second priority uplink transmission among multiple dynamically scheduled second priority uplink transmissions; or, starting from the earliest set duration after the last symbol of the DCI corresponding to each dynamically scheduled second priority uplink transmission among multiple dynamically scheduled second priority uplink transmissions.

[0091] For example, if uplink transmission 1 in the second uplink transmission is the first (earliest) dynamically scheduled uplink transmission of the second priority, then the first uplink transmission starts from the set time length after the last symbol (end point) of the DCI corresponding to uplink transmission 1, and the subsequent time domain symbols are canceled; or, the set time length is determined according to each uplink transmission in each second uplink transmission, for example, the set time length after the DCI corresponding to uplink transmission 1 is recorded as t1, the set time length after the DCI corresponding to uplink transmission 2 is recorded as t2, and the set time length after the DCI corresponding to uplink transmission 3 is recorded as t3, where t1 is earlier than t2 and t3, then the time domain symbols of the first uplink transmission after t1 are canceled.

[0092] In one embodiment, when the second uplink transmission is a dynamically scheduled, second-priority PUCCH for transmitting HARQ-ACK, the set duration may also start after (the end point of) the last symbol of the PDSCH corresponding to the HARQ-ACK. The method for determining the duration of the set duration here is the same as the method for determining the duration of the set duration when the second uplink transmission is a dynamically scheduled other second-priority uplink transmission.

In some embodiments, the first uplink transmission may also be SRS of the first priority or PUCCH for transmitting A-CSI of the first priority.

[0094] In this embodiment, the set duration is determined according to the type of the second uplink transmission. Different types of the second uplink transmission may also correspond to different set durations.

The time domains of these three uplink transmissions do not overlap, but they all overlap with the time domain of the first uplink transmission, and there is a conflict in the uplink transmission. In this case, the start symbol of the canceled transmission of the first uplink transmission is determined based on uplink transmission a, uplink transmission b, and uplink transmission c.

[0097] In one embodiment, the start symbol satisfies: starting from a set duration before the start symbol of the first semi-statically scheduled second-priority uplink transmission; or, starting from the earliest set duration before the start symbol corresponding to each semi-statically scheduled second-priority uplink transmission among multiple semi-statically scheduled second-priority uplink transmissions.

[0098] In this embodiment, the start symbol of the first uplink transmission whose transmission is canceled (at the latest) starts from the symbol corresponding to the set time length before the start symbol (starting point) of the first semi-statically scheduled second-priority uplink transmission, or (at the latest) starts from the set time length before the start symbol (starting point) of the first semi-statically scheduled second-priority uplink transmission. For example, if the uplink transmission a in the second uplink transmission is the first (earliest) semi-statically scheduled second-priority uplink transmission, then the first uplink transmission starts from the set time length before the start symbol (starting point) of the uplink transmission a, and the subsequent time domain symbols are canceled from transmission; or, the set time length is determined according to each uplink transmission in each second uplink transmission, for example, the set time length before the start symbol (starting point) of the uplink transmission a is recorded as t a , the set time length before the starting symbol (starting point) of uplink transmission b is recorded as t b , the set time length before the starting symbol (starting point) of the uplink transmission c is recorded as t c , where t a Earlier than t b and t c , then the first uplink transmission starts from t a The time domain symbols after the position are cancelled.
