Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This invention claims priority to a Chinese patent application submitted to the China Patent Office on March 12, 2021, bearing application number 202110269812.6 and titled "Uplink transmission method, apparatus and terminal", the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of mobile communication technology, and in particular to an uplink transmission method, device, and terminal. [Background technology]

[0003] Fifth generation mobile communication technology (5 th In the 5G (First Generation Mobile Communication Technology) communication process, the maximum number of repetitions of the Physical Uplink Shared Channel (PUSCH) is 16. DoubleIn the Time Division Duplex (TDD) mode, due to the carrier configuration dominated by the downlink slot, the uplink slot is very limited, and the number of repeated transmissions of PUSCH that actually occurs is much less than the configured number of repetitions, which limits its coverage. In addition, for PUSCH repetition transmission type A, the transmission carrying PUSCH in each slot is required to have the same time domain resource, so that some slots do not have the same time domain resource allocation, and therefore the transmission of PUSCH in this slot is abandoned even though these slots still have a certain number of uplink symbols. This also causes its coverage to be limited. In addition, with an invalid symbol pattern (InvalidSymbolPattern), it can only be applied to PUSCH repetition transmission type (Repetition Type) B, and cannot be applied to Repetition Type A or joint transmission of one transmission block in multi-slots (TB Processing Over Multi-slots, TBoMS), so that the PUSCH with resource collision can only be discarded to protect other transmissions or perform other physical processes.

[0004] As can be seen, a large amount of slot resources is thrown away, resulting in a decrease in uplink transmission efficiency. Summary of the Invention [Problem to be solved by the invention]

[0017] Hereinafter, the uplink transmission method according to the embodiment of the present application will be described in detail with reference to specific embodiments and application scenarios thereof in conjunction with the drawings.

[0018] 2 shows a flowchart of an uplink transmission method according to the present application. The method may be performed by a terminal, in other words, the method may be performed by software or hardware installed in the terminal. As shown in FIG. 2, the method may include the following steps:

[0019] Step S201, before transmitting a first symbol of an uplink transmission, determines an available or effective or nominal first slot for uplink transmission.

[0020] It should be understood that the uplink transmission may include a Physical Uplink Shared Channel (PUSCH) transmission and a Physical Uplink Control Channel transmission, specifically, a PUSCH transmission indicated by a Time domain resource allocation (TDRA). The first slot may be a slot or a sub-slot.

[0021] Step S202, determining an actual transmission behavior in the first slot.

[0022] Before performing uplink transmission, the terminal first determines whether each first slot for uplink transmission is an available or valid or nominal first slot. After determining the available or valid or nominal first slot, the terminal determines the actual transmission behavior in the first slot of the current uplink transmission. That is, the terminal determines how to realize the current uplink transmission in the first slot, for example, performing uplink transmission with rate matching using the first symbol, performing uplink transmission after deleting or puncturing the first symbol, performing uplink transmission after segmenting the uplink transmission using the first symbol, or abandoning the uplink transmission in the first slot.

[0023] Thereby, the uplink transmission method according to the embodiment of the present application can effectively improve the efficiency of uplink transmission by determining an available or effective or nominal first slot for uplink transmission and then determining the actual transmission behavior in the first slot.

[0024] 3 shows another flowchart of an uplink transmission method according to an embodiment of the present application. As shown in FIG. 3, the method may include the following steps:

[0025] Step S301: obtain a first number of symbols that meet a first condition among all first symbols included in the first slot, where the first symbols are symbols for uplink transmission in the first slot, and by meeting the first condition, the first symbols become invalid symbol resources for a PUSCH or a Physical Uplink Control Channel (PUCCH) of a current uplink transmission.

[0026] Furthermore, the first symbol is symbols for PUSCH transmission as indicated by the TDRA; Symbols for uplink transmission indicated by a higher layer configuration, the higher layer configuration specifically including symbols configured by a Radio Resource Control (RRC) message or a System Information Block (SIB) message; and a symbol for PUCCH transmission indicated by Physical Uplink Control Channel Resource Indicator (PRI) information.

[0027] Furthermore, the first condition is: 1) being configured as a semi-static downlink symbol (semi-static DL); 2) It is configured as a synchronization signal block (Synchronization Signal and PBCH block, SSB); 3) A control resource set (CORESET) for a Type 0 physical downlink control channel public search space (Type 0-PDCCH CSS); and 4) configured as a semi-static flexible symbol; 5) Unavailable or invalid symbols for uplink transmission configured by higher layers; and 6) Symbols that cannot be used for the current uplink transmission, as indicated by dynamic signaling or higher layer configuration; 7) interrupting the current physical uplink shared transmission due to a first cause; 8) canceling a current uplink transmission based on half-duplex rules.

[0028] Furthermore, the semi-static downlink symbol is time-division multiplexed. Double Uplink and downlink normal configuration (tdd-UL-DL-ConfigurationCommon) information and / or time division DoubleA semi-static downlink symbol configured by uplink / downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated) information; Furthermore, the SSB includes an SSB configured by a synchronization signal block burst position (ssb-PositionsInBurst) in the system information block SIB1 or an ssb-PositionsInBurst indication in the serving unit general configuration (ServingCellConfigCommon); Furthermore, the control resource set for the Type0-PDCCH CSS includes a control resource set for the Type0-PDCCH CSS configured by a system information block configuration (pdcch-ConfigSIB1) of a physical downlink control channel in a master information block (MIB), Furthermore, the semi-static flexible Double Uplink and downlink normal configuration (tdd-UL-DL-ConfigurationCommon) information and / or time division Double Including semi-static flexible configured by uplink / downlink dedicated configuration information (tdd-UL-DL-ConfigurationDedicated), Furthermore, the unavailable or invalid symbols for uplink transmission include unavailable or invalid symbols for uplink transmission configured by an invalid symbol pattern, and include unavailable or invalid symbols for PUSCH transmission.

[0029] Further, as indicated by the dynamic signaling or higher layer configuration, symbols that are not available for the current uplink transmission are A symbol scheduled as a downlink (DL) symbol; A symbol that is scheduled as a dynamic flexible symbol; symbols for scheduling downlink transmissions; a symbol for scheduling another uplink repeat transmission; a symbol for scheduling other uplink multi-slot transmissions, which is a TBoMS; and and unavailable or invalid symbols.

[0030] Furthermore, the symbols that cannot be used for the current uplink transmission are: A dynamic slot format indication (dynamic SFI) for indicating that the first symbol is DL and / or dynamic flexible; The first symbol is for scheduling a downlink transmission, or a higher priority uplink transmission, or another uplink repeated transmission, or another uplink multi-slot transmission, or is an unavailable or invalid symbol, i.e., Downlink Control Information (DCI) for indicating that the resources occupied for the repeated transmission overlap with the first symbol; an upper layer configuration for configuring the first symbol as for another uplink repeat transmission or another uplink multislot transmission; and uplink transmission cancellation signaling (UL Cancellation indication, UL CI).

[0031] Furthermore, the repeat transmission of the other uplink repetitive transmission of a physical uplink control channel (PUCCH repetition), the physical uplink control channel including a physical uplink control channel for channel state information and / or a scheduling request and / or a hybrid automatic repeat request; Information 3 (Msg3) and / or Information A (MsgA ) Repeat n Repeated transmission of target information including: and repeated transmission of an uplink transmission having a higher priority than the current uplink transmission.

[0032] Further, a first factor that can interrupt a current uplink transmission of a first symbol is: Time resource of scheduling restriction due to a first measurement (the first measurement is used for at least one of Radio Link Monitoring (RLM), link recovery, Radio resource management (RRM), and Reference Signal Received Power (RSRP) of the L1 layer). The time resource of the scheduling constraint according to the first measurement is: Specifically, the SSB channel state information reference signal (CSI-RS) transmission symbol or a number of symbols before and after the symbol, The switching or conversion time between uplink and downlink links (i.e., switching or conversion time from DL to UL or from UL to DL); RF retuning of the radio frequency front end between same or different uplink transmissions (same or different uplink transmissions refer to the transmission content and / or the channel or reference signal transmitted being the same or different); Bandwidth Part (BWP) switching of the current cell or other cells, activation of a secondary cell (Scell), deactivation of a secondary cell, addition of a secondary cell, release of a secondary cell, A conversion between non-discontinuous reception (Non-DRX) and discontinuous reception (DRX) of another serving cell (i.e., a conversion from Non-DRX to DRX or from DRX to Non-DRX has occurred in another serving cell); and a measurement gap.

[0033] Furthermore, the retuning time of the radio frequency front end between the same or different uplink transmissions may be The change in the uplink transmission spatial relation of different slots; and frequency hopping transmissions performed by a bandwidth-limited terminal at a bandwidth exceeding its maximum bandwidth.

[0034] Further, in the first condition, the half-duplex rule for canceling the current uplink transmission is: half duplex time division Double Carrier aggregation (TDD Half-duplex CA) terminal behavior and Half-duplex frequency division for Reduced Capability devices (RedCap) Double (Half-duplex FDD) terminal behavior.

[0035] For different uplink transmissions, a corresponding first condition can be selected from each of the above first conditions, and whether each first symbol is an invalid symbol resource can be determined based on the corresponding first condition, and further the first slot can be determined to be an available or valid or nominal first slot. Classification of physical uplink shared channels; Physical uplink control channel format; and uplink control information (UCI) carried on a physical uplink control channel.

[0036] For PUSCH transmission, different first conditions can be adopted according to different classifications of PUSCH. For PUCCH transmission, different first conditions can be adopted according to PUCCH formats and / or different UCIs carried in the PUCCH. Specifically, the following is an example:

[0037] For a dynamically scheduled PUSCH, the corresponding first condition includes the above conditions 1), 2), 5), 7), and 8); For a dynamically scheduled PUCCH, for example, the PUCCH carries a downlink hybrid automatic repeat request acknowledgement (HARQ-ACK) for dynamic scheduling, and the first condition corresponding thereto includes the above conditions 1), 2), 5), 7), and 8).

[0038] For an RRC-connected UE, the corresponding first conditions for its configured grant PUSCH (CG PUSCH) include the above conditions 1), 2), 3), 5), 6), 7), and 8).

[0039] For an RRC-connected UE, the corresponding first conditions for semi-statically configured PUCCH transmission, such as Scheduling Request (SR), Persistent Channel State Information (P-CSI), Semi-Persistent Channel State Information (SP-CSI), etc., include the above conditions 1), 2), 3), 5), 6), 7), and 8).

[0040] For an RRC-idle / inactive UE, the corresponding first conditions for its configuration permission PUSCH include the above conditions 1), 2), 3), 7), and 8).

[0041] For the MsgA PUSCH message, the corresponding first condition includes the above conditions 1), 2) and 8).

[0042] Step S302, if the first number is less than a first threshold X, determine that the first slot is an available or valid or nominal first slot.

[0043] Furthermore, the first threshold value X is A configuration of an upper layer including an RRC and an SIB; Dynamic instructions and the transmission length in the TDRA; a transmission length of the physical uplink control channel; and the transmission length of the uplink transmission; A configuration according to the time domain resource allocation table; A configuration according to radio resource control information; the first slot being a slot without uplink / downlink switching; the first slot being a slot with uplink / downlink switching; If the coding rate > R for the LX symbols of data currently being transmitted, as determined by at least one of the coding rate R configured by higher layers and / or the coding rate R specified by the protocol, then the slot is unavailable.

[0044] Here, when determining the first threshold value X based on the transmission length L, one first threshold value X can be determined for each transmission length L, and the first threshold value X can also be recorded in the TDRA. The configuration of the first threshold value is specifically exemplified as follows:

[0045] The first threshold may be configured in the TDRA as shown in Table 1.

[0046] [Table 1]

[0047] Table 1 is an exemplary description of PUSCH time domain resource allocation for normal CP, where S and L in each row indicate the start symbol and transmission length of the scheduled PUSCH, PUSCH Mapping Type indicates the mapping type of the dedicated demodulation reference signal (DM-RS), and the K2 parameter indicates the slot offset of the slot in which the first PUSCH is located with respect to the slot in which the scheduling DCI is located.

[0048] The first threshold may be configured by the RRC, and a first threshold X is defined for each transmission length L of uplink transmissions of different priorities, as shown in the following Tables 2 and 3, where Table 2 is for a high-priority PUSCH and Table 3 is for a low-priority PUSCH.

[0049] [Table 2]

[0050] [Table 3]

[0051] For slots without uplink and downlink switching and slots with uplink and downlink switching, corresponding first thresholds X are configured as shown in Tables 4 to 7 below.

[0052] [Table 4]

[0053] [Table 5]

[0054] [Table 6]

[0055] [Table 7]

[0056] Here, Table 4 is an uplink slot, and the corresponding first threshold X is 1. Tables 5, 6, and 7 are slots with uplink and downlink switching. In the slots corresponding to Table 5, DL:Flexible:UL=6:2:6, and the corresponding first threshold X is 7, in the slots corresponding to Table 6, DL:Flexible:UL=9:3:2, and the corresponding first threshold X is 1, and in the slots corresponding to Table 7, DL:Flexible:UL=2:2:10, and the corresponding first threshold X is 4.

[0057] Furthermore, the first threshold value is equal to or greater than 0 and equal to or less than 13.

[0058] FIG. 4 shows a schematic diagram of a slot scheduling scheme according to an embodiment of the present application, in which slot 0 (Slot#0) and slot 1 (Slot#1) in FIG. 4 are configured by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and each slot has a total of 14 OFDM symbols, where symbol D is a symbol for downlink transmission, symbol F is a flexible symbol, and symbol U is a symbol for uplink transmission; and according to demand, the symbol corresponding to T1 is configured as SSB, and the symbol corresponding to T2 is indicated as not capable of transmitting PUSCH by dynamic signaling.

[0059] Suppose the PUSCH transmission length L is 5 and the first threshold x=1. When the first condition includes conditions 1) and 2), it can be determined that Slot#0 in FIG. 4 is an unavailable slot, and Slot#1 is an available slot.

[0060] When the first condition includes conditions 1), 2), 3), and 4), it can be determined that Slot#0 in FIG. 4 is an unavailable slot, and Slot#1 is an unavailable slot.

[0061] When the first condition includes conditions 1), 2), 3), and 6), it can be determined that Slot#0 in FIG. 4 is an unavailable slot, and Slot#1 is an available slot.

[0062] Suppose the PUSCH transmission length L is 6 and the first threshold x=1. When the first condition includes conditions 1), 2), 3), and 6), it can be determined that Slot#0 in FIG. 4 is an unavailable slot, and Slot#1 is an unavailable slot.

[0063] Suppose the PUSCH transmission length L is 6 and the first threshold X=2. When the first condition includes conditions 1), 2), 3), and 6), it can be determined that Slot#0 in FIG. 4 is an unavailable slot, and Slot#1 is an available slot.

[0064] FIG. 5 shows a schematic diagram of another slot scheduling scheme according to an embodiment of the present application, in which the symbol corresponding to T1 is configured as an SSB, the symbol corresponding to T3 is indicated as a downlink reception DL by dynamic signaling, and a measurement interval exists in Slot#0.

[0065] Suppose the PUSCH transmission length L is 4 and the first threshold x=1. If the first condition includes conditions 1), 2), 3), and 7) and the uplink / downlink switching time is two symbols, it can be determined that Slot#0 in FIG. 5 is an unavailable slot, and Slot#1 is an unavailable slot.

[0066] If the first condition includes conditions 1), 2), 3), and 7) and the uplink / downlink switching time is one symbol, it can be determined that Slot #0 in FIG. 5 is an unavailable slot and Slot #1 is an available slot.

[0067] Suppose the PUSCH transmission length is 4 and the first threshold X=2. If the first condition includes conditions 1), 2), 3), and 7) and the uplink / downlink switching time is two symbols, it can be determined that Slot#0 in FIG. 5 is an unavailable slot and Slot#1 is an available slot.

[0068] Step S303: determining an actual transmission behavior in the first slot.

[0069] Step S303 may realize an embodiment of the method of step S202 in FIG. 2, and obtain the same or similar technical effects, and for the sake of brevity, the same parts will not be further described here.

[0070] Therefore, the uplink transmission method according to the embodiment of the present application obtains a first number of symbols that meet a first condition among all first symbols included in the first slot, and determines whether the first slot is available based on a comparison result between the first number and a preset first threshold, and then determines an actual transmission behavior in the first slot, so that the judgment of whether the first slot is available is more accurate, and the efficiency of uplink transmission is effectively improved.

[0071] FIG. 6 shows another flowchart of an uplink transmission method according to an embodiment of the present application, and as shown in FIG. 6, the method may include the following steps.

[0072] Step S601: obtain a first number of symbols that meet a first condition among all first symbols included in the first slot.

[0073] Step S602, if the first number is less than a first threshold X, determine that the first slot is an available or valid or nominal first slot.

[0074] The steps S601 to S602 implement an embodiment of the method of steps S301 to S302 in FIG. 3, and can obtain the same or similar technical effects, and for the sake of brevity, the same parts will not be further described here.

[0075] Step S603: determining a second number Y of symbols that meet a second condition among all the first symbols.

[0076] Here, the second condition is a condition of the first condition excluding the condition of being configured as a semi-static downlink symbol. That is, if the first condition includes condition 1), the second condition is the first condition excluding condition 1), and if the first condition does not include condition 1), the second condition is the same as the first condition.

[0077] Step S604: Determine the actual transmission behavior in the first slot based on the second number Y.

[0078] Furthermore, step S604 includes: When the second number is greater than or equal to the first number, i.e., Y≥X, the terminal abandons the transmission in the first slot; When the second number is less than the first number, i.e., Y<X, determine the actual transmission behavior in the first slot. Specifically, it includes: Execute the actual transmission behavior of the target in the first slot; When the first symbol of the first slot (excluding invalid symbol resources) does not include DMRS, abandon the transmission in the first slot; Execute the actual transmission behavior of the target based on the second number Y; Determine the execution of the actual transmission behavior of the target in the first slot by the upper layer configuration; Include at least one of determining the actual transmission behavior of each symbol in the first slot based on the processing time. Here, the actual transmission behavior of the target includes: Perform rate - matching for the current uplink transmission with respect to invalid symbol resources; Perform deletion or puncturing of the invalid symbol resources for the current uplink transmission; Perform segmentation and transmission by the invalid symbol resources for the current uplink transmission; Include at least one of abandoning the transmission in the first slot.

[0079] Here, executing the actual transmission behavior of the target based on the second number means: by rate matching to an unused symbol resource in the first slot if the second number is greater than a third number X1 and less than the first number, i.e., X1≦Y≦X; if the second number is less than or equal to a third number, i.e., Y≦X1, performing uplink transmission in the first slot by deleting or puncturing invalid symbol resources; Here, the third number is configured by a higher layer or agreed upon by a protocol.

[0080] Moreover, determining an actual transmission behavior of each symbol in the first slot based on a processing time includes: performing uplink transmission in the first slot that is rate-matched to an unavailable or invalid first symbol that is semi-statically indicated; and performing an uplink transmission after deleting or puncturing a dynamically indicated unavailable or invalid first symbol in the first slot.

[0081] Moreover, determining an actual transmission behavior of each symbol in the first slot based on a processing time includes: When the interval between the start symbol j of uplink transmission and the last symbol i in which the received dynamic signaling is located is equal to or greater than the terminal processing capability value T_process, i.e., ji≧T_process, performing uplink transmission in the first slot with rate matching for the dynamically indicated unavailable or invalid first symbol; If the interval between the start symbol of the uplink transmission and the last symbol where the received dynamic signaling is located is smaller than the processing capability value of the terminal, that is, j - i < T_process, then in the first slot, after deleting or puncturing the first symbol that is dynamically indicated as unavailable or invalid, perform uplink transmission, or perform uplink transmission after ignoring the first symbol that is dynamically indicated as unavailable or invalid.

[0082] FIG. 7 shows a schematic diagram of another slot scheduling scheme according to an embodiment of the present application. As shown in FIG. 7, the symbol corresponding to T1 is configured as an SSB, and the symbol corresponding to T4 is indicated as one that cannot transmit PUSCH by dynamic signaling.

[0083] Assuming that the first condition includes conditions 1), 2), and 3), it can be determined that both Slot#0 and slot#1 are available slots.

[0084] In the determined available slot, in Slot#1, PUSCH transmission is performed from symbol 8 to 13. Here, symbol 8 and symbol 9 cannot be used for PUSCH transmission. That is, (Y = 2) = (X = 2), and the terminal abandons PUSCH transmission in slot slot#1. In Slot#0, PUSCH transmission is performed from symbol 8 to 13. Here, symbol 8 cannot be used for PUSCH transmission. That is, (Y = 1) < (X = 2), and the terminal can transmit in slot slot#0.

[0085] Thereby, the uplink transmission method according to the embodiment of the present application determines the second number of symbols that meet the second condition among all the first symbols, and determines the actual transmission behavior in the first slot based on the second number, so as to perform uplink transmission flexibly in the first slot and effectively improve the efficiency of uplink transmission.

[0086] It should be noted that the execution body of the uplink transmission method according to the embodiment of the present application may be an uplink transmission device or a control module for executing the uplink transmission method in the uplink transmission device. In the embodiment of the present application, the execution of the uplink transmission method by the uplink transmission device is taken as an example to describe the uplink transmission device according to the embodiment of the present application.

[0087] FIG. 8 shows a structural schematic diagram of an uplink transmission device according to an embodiment of the present application. As shown in FIG. 8, the device includes: a determining module 801 and a transmitting module 802.

[0088] The judgment module 801 is used to determine an available or valid or nominal first slot for uplink transmission before transmitting the first symbol of the uplink transmission, and the transmission module 802 is used to determine the actual transmission behavior in the first slot.

[0089] As a result, the uplink transmission device according to the embodiment of the present application can effectively improve the efficiency of uplink transmission by determining an available or effective or nominal first slot for uplink transmission and then determining the actual transmission behavior in the first slot.
