Description

Technical Field

[0001] The present application relates to the field of communications, and in particular, to a method and device for sending information. Background Art

[0002] At present, the first phase of the standard setting work for the 5th Generation mobile communication technology (5G) has been completed. From the perspective of standard setting and technology development trends, the 5G system is committed to researching technical indicators such as higher speed (Gbps), massive links (1M / Km2), ultra-low latency (1ms), higher reliability, and 100-fold energy efficiency improvement to support new demand changes.

[0003] In the first phase of 5G, dynamic scheduling-based slot aggregation and scheduling-free slot repetitions are introduced to ensure coverage. This means that the terminal uses multiple slots to repeatedly send transport blocks (TB), and TB has the same time domain resource allocation in each slot. The current length of aggregable or repeatable slots is 1 / 2 / 4 / 8. In the second phase of 5G, in order to support the characteristics of ultra-high reliability and ultra-low latency transmission, and to complete the transmission of low-latency and high-reliability services in a shorter transmission time, it is necessary to enhance the uplink aggregation transmission based on dynamic scheduling and the uplink repetition transmission without scheduling, so mini-slot based repeated transmission of TB is introduced.

The configuration information is obtained by any of the following methods: RRC (Radio Resource Control) signaling, or DCI (Downlink Control Information) signaling. The embodiments of the present application are described in detail below with specific examples.

[0156] Moreover, in the embodiments of the present application, only uplink transmission is used as an example. It can be understood that the technical solution can also be used for downlink, and can also be used for other physical layer channels of 4G or 5G, such as control channels, random access channels, and data channels.

[0157] Example 1

[0158] This embodiment provides one of the following methods for determining the transmission opportunity #t, where #t is the index of the transmission opportunity, t is an integer, and 0<t≤Q. Figure 3 The actual repetition #4 is the transmission opportunity #t. In the embodiment, the time domain symbol where the transmission opportunity #t is located is defined as an "isolated" symbol.

[0159] Mode 1: If the time domain symbol of a certain transmission opportunity is less than a predefined value N, then the transmission opportunity is transmission opportunity #t, wherein the time domain symbol of transmission opportunity #t is an "isolated" symbol.

[0160] Furthermore, N is an integer greater than or equal to 1, for example, N=2.

[0161] Furthermore, N has different values ​​depending on the uplink waveform. If the uplink is CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplexing), then N is 2, and if the uplink is SC-FDMA (Single-Carrier Frequency-Division Multiple Access), N is 3.

[0162] Furthermore, the predefined value N may be notified by RRC signaling or DCI signaling.

[0163] Figure 3 is a schematic diagram of a transmission opportunity #t according to an embodiment of the present application Figure 1 ,like Figure 3 As shown, the nominal transmission opportunity #3 (nominal repetition #3) is divided into actual transmission opportunities #3 and #4 (actual repetition, #3 and #4) across the slot boundary. Then the time domain symbol of the actual transmission opportunity #4 is less than 2, so it is transmission opportunity #t, where the time domain symbol of transmission opportunity #t is an "isolated" symbol.

[0164] Mode 2: If the time domain symbol of a certain transmission opportunity is less than M=f(L), then the transmission opportunity is transmission opportunity #t, wherein the time domain symbol of transmission opportunity #t is an "isolated" symbol.

[0165] Further, L is the time domain symbol length of a transmission opportunity in the nominal transmission opportunities; or L is the time domain symbol length of the actual first transmission opportunity; or L is the total time domain symbol length of all actual transmission opportunities; or L is the shortest time domain symbol length in the actual transmission opportunities; or L is the time domain symbol length of the nominal transmission opportunity or the actual transmission opportunity corresponding to any one of RV (Redundancy Version) = {0,1,2,3}; or L is the longest time domain symbol length in the actual transmission opportunities.

[0166] Furthermore, or Wherein X is an integer greater than or equal to 1, for example, X=2.

[0167] Figure 3 is a schematic diagram of a transmission opportunity #t according to an embodiment of the present application Figure 1 ,like Figure 3 As shown, L = 3, which is the time domain symbol length of the first actual transmission opportunity. X = 2, then Then the time domain symbol length of actual transmission opportunity #4 is 1 symbol less than f(L)=2, so actual transmission opportunity #4 is transmission opportunity #t, and the time domain symbol of actual transmission opportunity #4 is an "isolated" symbol.

[0168] Mode 3: If the target code rate of the transport block size TBS carried on a certain transmission opportunity is greater than the predefined target code rate, then the transmission opportunity is transmission opportunity #t, and the time domain symbol of transmission opportunity #t is an "isolated" symbol.

[0169] Furthermore, the predefined target code rate is notified by RRC or DCI, or is obtained according to the target code rate in the MCS (Modulation and Coding Scheme) index.

[0170] like Figure 3 As shown, TBS is determined by the time domain symbol length of the first transmission opportunity, and the predefined target code rate is 1 / 3, while the target code rate determined by the time domain symbol length of the actual transmission opportunity #4 is 1 / 2, so the time domain symbol length of the actual transmission opportunity #4 is an "isolated" symbol.

[0171] Alternatively, the predefined target code rate is Y, where Y can be any number from 0 to 1, including decimals. For example, Y=0.98, if the code rate corresponding to the TBS determined by a certain nominal or actual transmission opportunity is greater than Y=0.98, then the time domain length corresponding to the transmission opportunity is an "isolated" symbol.

[0173] For the transmission opportunity #t generated in Example 1 and when the time domain symbol of the transmission opportunity #t is an "isolated" symbol, the terminal behavior may be any of the following.

[0174] Mode 1: The terminal does not send any information in transmission opportunity #t, including service data, control data, random access information and DMRS.

[0175] Furthermore, within the same time slot, the time domain symbol position corresponding to transmission opportunity #t and the time domain symbol positions corresponding to other transmission opportunities are non-continuous in the time domain, then no information is sent on the transmission opportunity #t, including service data, control information, random access information and DMRS, etc.

[0176] Furthermore, the transmission opportunity #t is not counted in the number of repetitions and the repetition index, that is, the transmission opportunity #t is skipped, and the transmission opportunity index is sequentially numbered at the next available transmission opportunity.

[0177] Mode 2: The terminal sends DMRS at transmission opportunity #t. Figure 4 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 1 ,like Figure 4 shown.

[0178] Further, the terminal sends DMRS on all time domain symbols corresponding to transmission opportunity #t;

[0179] Alternatively, the DMRS may be sent on a time domain symbol corresponding to the terminal transmission opportunity #t.

[0180] Method 3: Figure 5is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 2 ,like Figure 5 As shown, in the same time slot, the time domain symbol positions of transmission opportunity #t and other transmission opportunities are continuous in the time domain, so a new transmission opportunity is formed, and the terminal sends a physical uplink shared channel (Physical Uplink Shared Channel, referred to as PUSCH) on the time domain symbol corresponding to the new transmission opportunity.

[0181] In addition, if the method given in Example 1 is not satisfied, no transmission opportunity #t is formed, and the terminal sends PUSCH including DMRS and service data / control data in non-transmission opportunity #t. Figure 3 The actual transmission opportunity #3, that is, the actual transmission opportunity #3 is not the transmission opportunity #t.

[0182] Example 3

[0183] Figure 6 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 3 ,like Figure 6 As shown in the figure, if the base station enables the intra-repetition frequency hopping function within the transmission opportunity, that is, the frequency hopping within the transmission opportunity, then after the intra-repetition frequency hopping is completed on a certain transmission opportunity, when the time domain symbol of the first hop or the second hop of the transmission opportunity is less than the predefined Z or Z=f(L), the transmission opportunity will not perform the intra-repetition frequency hopping. That is to say, for each transmission opportunity, whether the frequency hopping is enabled or the frequency hopping pattern may be different.

[0184] Furthermore, if the base station enables the intra-repetition frequency hopping function, after the intra-repetition frequency hopping is enabled for a certain transmission opportunity, when the time domain symbol of the first hop or the second hop is an isolated symbol, when DMRS is sent on the isolated symbol, then the frequency domain position of the first hop or the second hop of the certain transmission opportunity is the same as the frequency domain position of the previous continuous transmission opportunity in the time domain or the next continuous transmission opportunity in the time domain. Figure 6 After intra-repetition frequency hopping is enabled in transmission opportunity #2, the time domain symbol of the first hop is 1 symbol, the time domain symbol of the second hop is 5 symbols, and the DMRS carried on the first hop is an isolated symbol, so the frequency domain position of the first hop of transmission opportunity #2 is the same as the frequency domain position of the second hop of transmission opportunity #1.

[0185] Furthermore, when the transmission opportunity time domain duration corresponding to the normative repetition is 14 symbols, the additional DMRS is enabled. Assuming that there are 3 DMRS in total, but after intra-repetition, the transmission opportunity #1 of a certain PUSCH is divided into 6 symbols of the first hop and 8 symbols of the second hop. Then according to Rel-15, when PUSCH is equal to 8 symbols, there are 3 DMRS, and the total number of DMRS of these two transmissions is greater than the PUSCH transmission of the normative repetition, thereby enabling low spectrum efficiency. Therefore, when the PUSCH transmission of a certain normative repetition is divided into the first hop and the second hop, and the total number of DMRS of the first hop and the second hop is greater than the number of DMRS of the PUSCH transmission of a certain normative repetition, the additional DMRS is not set through high-level signaling or DCI.

[0186] Figure 7 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 4 ,like Figure 7 As shown, if the base station has enabled the inter-repetition frequency hopping function, then when a certain transmission opportunity undergoes inter-repetition frequency hopping, that is, frequency hopping between different transmission opportunities, and the time domain resources of the transmission opportunity are less than the predefined Z or Z=f(L), the transmission opportunity will not perform inter-repetition frequency hopping. Furthermore, the frequency domain position of the transmission opportunity is the same as the frequency domain position of the previous transmission opportunity in the time domain, or the frequency domain position of the transmission opportunity is the same as the frequency domain position of the next transmission opportunity in the time domain. Alternatively, the frequency domain position of the transmission opportunity is the same as the frequency domain position of a certain continuous transmission opportunity in the time domain. As Figure 7 , transmission opportunity #4 is the above-mentioned transmission opportunity #t, so the frequency domain position of transmission opportunity #4 is the same as that of transmission opportunity #5.

[0187] Wherein, Z is an integer greater than or equal to 1, for example, Z=2.

[0188] Furthermore, Z has different values ​​depending on the uplink waveform. If the uplink is CP-OFDM, then Z is 2, and if the uplink is SC-FDMA, then Z is 3.

[0189] Furthermore, the predefined value Z may be notified by RRC signaling or DCI signaling.

[0190] in, or

[0191] Where X is an integer greater than or equal to 1, for example, X = 2. L is the time domain symbol length of a transmission opportunity in the nominal transmission opportunity; or L is the time domain symbol length of the actual first transmission opportunity; or L is the total time domain symbol length of all actual transmission opportunities; or L is the shortest time domain symbol length in the actual transmission opportunity; or L is the time domain symbol length of the nominal transmission opportunity or the actual transmission opportunity corresponding to any one of RV (Redundancy Version) = {0, 1, 2, 3}; or L is the longest time domain symbol length in the actual transmission opportunity.

[0192] Example 4

[0193] For type 1 (PUSCH transmission type scheduled by RRC signaling) or type 2 (PUSCH transmission type scheduled by activation DCI) of unscheduled transmission, when a transmission opportunity on a set of resources collides with a subframe format, the terminal behavior can be any of the following. Furthermore, the transmission opportunity collides with a subframe means that all or part of the time domain symbols corresponding to the transmission opportunity are downlink or flexible symbols.

[0194] Method 1: Do not cross period P, and extend the collision transmission opportunity backward in the time domain. If it is extended backward in the time domain, it will cross period P, and the terminal will not extend the collision transmission backward in the time domain. Figure 8 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 5 ,like Figure 8 As shown, when symbol #8 and symbol #9 where transmission opportunity #2 is located collide with the subframe format, that is, when the uplink transmission encounters a subframe format with a transmission direction of D or F, the terminal extends transmission opportunity #2 backward to symbol #10 to symbol #13, without crossing period P. Symbol #6 to symbol #9 do not send any information.

[0195] Method 2: Merge the non-colliding symbols corresponding to the transmission opportunity into a certain continuous transmission opportunity in the time domain. Fig. 9 As shown, symbol #6 and symbol #7 are combined into transmission opportunity #1 to form a new transmission opportunity #1. Further, no collision means that the time domain symbol of the transmission opportunity is an uplink symbol.

[0196] Method 3: Fig. 9 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 6 ,like Fig. 9 As shown, the non-colliding symbols corresponding to transmission opportunity #2 are merged into the continuous transmission opportunity #1 in the time domain, and the terminal also extends transmission opportunity #2 backward to symbol #10 to symbol #13 for transmission without crossing period P.

[0197] Method 4: Fig.10 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 7 ,like Fig.10 As shown, no information is sent on the colliding symbols corresponding to transmission opportunity #2, namely, symbol #8 and symbol #9, and PUSCH is sent only on the non-colliding symbols corresponding to transmission opportunity #2, namely, symbol #6 and symbol #7.

[0198] Method 5: Fig.11 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 8 ,like Fig.11 As shown, no information is sent on the colliding symbols corresponding to transmission opportunity #2, namely, symbol #8 and symbol #9, and repeated transmission of PUSCH is sent only on the non-colliding symbols corresponding to transmission opportunity #2, namely, symbol #6 and symbol #7. In addition, the terminal also extends transmission opportunity #2 to symbol #10 to symbol #13, without crossing period P.

[0199] Mode 6: The terminal selects a set of resources that does not collide with the subframe format to send the transport block.

[0200] Mode 7: When the alignment time of a set of resources that do not collide with the subframe format is compared with threshold A and is less than or equal to threshold A, the terminal selects to send a transport block on the set of resources.

[0201] The alignment time refers to the time interval between the start position of the time domain symbol where the first transmission opportunity of a set of resources is located and the arrival of the service.

[0202] When the alignment time of a set of resources that do not collide with the subframe format is compared with threshold A and is greater than threshold A, the terminal selects a set of configurations to send PUSCH according to the principle of minimum delay, wherein the alignment time is the time interval between the start position of the time domain symbol where the first transmission opportunity is located and the arrival of the service. Further, the behavior of the terminal sending a transmission block on this set of resources can adopt any one of Modes 1 to 5. Among them, the minimum delay means that the time interval between the start position of the time domain symbol where the first transmission opportunity of a set of resources is located and the arrival of the service is the smallest compared to the time domain symbol start position where the first transmission opportunity of other configurations is located.

[0203] Fig.12 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 9 ,like Fig.12 As shown, among the four configurations, only configuration #4 does not collide with the subframe format. If the alignment time is compared with threshold A and is less than threshold A, the transport block is sent on configuration #4. If the alignment time is compared with threshold A and is greater than threshold A, configuration #1 with the smallest alignment time is selected to send the transport block.

[0204] Mode 8: The terminal selects the resource with the least collision symbols with the subframe format to send the transport block, such as Fig.12 Configuration #4. When encountering two or more resource configurations with the same number of collision symbols as the subframe format, the resource configuration with the smallest alignment time is selected to send the transport block.

[0205] Example 5

[0206] The same transmission block has Q transmission opportunities in R consecutive time slots, and the time domain resource information of the Q transmission opportunities can be obtained in any of the following ways: wherein Q is an integer greater than or equal to 1, and R is an integer of 0<R≤Q

[0207] Method 1:

[0208] One transport block is sent through Y repeated transmissions, wherein the time domain resource information of the Y repeated transmissions includes at least one of the following information combinations:

[0209] Information combination 1: the starting symbol (Si) of the i-th transmission opportunity, the time domain duration (Li) of the i-th transmission opportunity, and the time slot index where the i-th transmission opportunity is located. Alternatively, the starting symbol (Si) of the i-th transmission opportunity, the time domain duration (Li) of the i-th transmission opportunity, and the time slot index starting from the second transmission opportunity.

[0210] Information combination 2: the start and length indication value SLIVi of the i-th transmission opportunity and the time slot index where the i-th transmission opportunity is located. Alternatively, the start and length indication value SLIVi of the i-th transmission opportunity and the time slot index starting from the second transmission opportunity.

[0211] The time domain start symbol (Si) and the time domain duration (Li) of the i-th transmission opportunity can be obtained through SLIV, where i is an integer, 0<i≤Q.

[0212] The time domain resource information is configured by a high layer;

[0213] Furthermore, the time domain resource information is jointly indicated by a high-level configuration and a high-level control signaling. Alternatively, the time domain resource information is jointly indicated by a high-level configuration and a dynamic control signaling.

[0214] Furthermore, the time slot index of the first transmission opportunity is determined by timing (slot offset K2), wherein the timing refers to the time from sending DCI in downlink to sending PUSCH in uplink.

[0215] The high-level configuration of the time domain resource allocation is shown in Table 1. It should be noted that the high-level configuration of the time domain resource allocation parameters also includes other control fields, which are not repeated here. As shown in Table 1, slot index 1 is the time slot index of the first transmission opportunity, which is obtained according to slot offset K2, that is, the time from sending DCI downlink to sending PUSCH uplink.

[0216] Table 1

[0217]

[0218] Furthermore, the value of slot index i can be the specific slot index where the i-th transmission opportunity is located; as shown in Table 1, when Row index = 1, slot index 1 = 0 means that the time slot index of the first transmission opportunity is slot#0; slotindex 2 = 2 means that the time slot index of the second transmission opportunity is slot#2.

[0219] Furthermore, the value of slot index i can also be the time slot offset compared to the slot index where the first transmission opportunity is located. As shown in Table 1, when Row index = 2, the first transmission opportunity is in slot #1, and the value of slot2index is 2, which means that the time slot index of the second transmission opportunity is 1+2=3, that is, in slot #3.

[0220] Furthermore, the value of slot index i can also be the time slot offset of the slot index where the previous slot index (i-1) is transmitted. For example, the second transmission opportunity is in slot #1. If the value of slot 3index is 0, it means that the third repetition is in 1+0=1, that is, in slot #1, that is, in the same time slot.

[0221] Method 2:

[0222] One transport block is sent through Y repeated transmissions, wherein the time domain resource information of the Y repeated transmissions includes at least one of the following information combinations:

[0223] Information combination three: the starting symbol of the i-th transmission opportunity (Si), the time domain duration of the i-th transmission opportunity (Li), and the cross-slot indication.

[0224] Information combination four: the start and length indication value SLIVi of the i-th transmission opportunity and the cross-slot indication.

[0225] Among them, the time domain start symbol (Si) and time domain duration (Li) of the i-th transmission opportunity can be obtained through SLIV.

[0226] The cross-time slot indication is related to the number of repeated transmissions / number of transmission opportunities;

[0227] The time domain resource information is configured by a high layer;

[0228] Furthermore, the time domain resource information is jointly indicated by a high-level configuration and a high-level control signaling. Alternatively, the time domain resource information is jointly indicated by a high-level configuration and a dynamic control signaling.

[0229] The cross-slot indication indicates the information of the time slot where the time domain resource SLIV of the current transmission opportunity is located. Furthermore, the cross-slot indication field is composed of multiple bits, namely a bitmap indication. When the bits in the field are flipped, it indicates that the time slot index where the time domain resource SLIV of the current transmission opportunity is located has changed compared to the time slot index where the time domain resource SLIV of the previous transmission opportunity is located. Furthermore, the first bit of the cross-slot indication indicates the time slot index information of the second transmission opportunity. Because the time slot information of the first transmission opportunity is determined according to the timing (slot offsetK2), where the timing refers to the time from sending DCI downlink to sending PUSCH uplink.

[0230] As shown in Table 2, the value of the cross-slot indication of entry=1 is 110, which means that the first transmission opportunity and the second transmission opportunity are not in the same slot, and the third and fourth transmission opportunities are not in the same slot. For example, the time domain symbol of the first transmission opportunity is in slot#1, the time domain symbol of the second transmission opportunity is in slot#2, the time domain symbol of the third transmission opportunity is in slot#2, and the time domain symbol of the fourth transmission opportunity is in slot#3. Slot index 1 is the time slot index of the first transmission opportunity, which is obtained according to slot offset K2.

[0231] Alternatively, a bit flip indicates crossing a slot boundary. For example, it is predefined that 0 is in the same slot, and 1 indicates a bit flip and crossing a slot boundary.

[0232] As shown in Table 2, the value of the cross-time slot indication of entry=1 is 110, which means that the first transmission opportunity and the second transmission opportunity are not in the same slot, and the third and fourth transmission opportunities are not in the same slot. For example, the time domain resources of the first transmission opportunity are in slot#1, the time domain resources of the second transmission opportunity are in slot#2, the time domain resources of the third transmission opportunity are in slot#3, and the time domain resources of the fourth transmission opportunity are in slot#3.

[0233] Table 2

[0234]

[0235] Method 3:

[0236] One transport block is sent through Y repeated transmissions, wherein the time domain resource information of the Y repeated transmissions includes at least one of the following information combinations:

[0237] Information combination five: the starting symbol of the i-th transmission opportunity (Si), and the time domain duration of the i-th transmission opportunity (Li).

[0238] Information combination six: the start and length indication value SLIVi of the i-th transmission opportunity.

[0239] Among them, the time domain start symbol (Si) and time domain duration (Li) of the i-th transmission opportunity can be obtained through SLIV.

[0240] The time domain resource information is configured by a high layer;

[0241] Furthermore, the time domain resource information is jointly indicated by a high-level configuration and a high-level control signaling. Alternatively, the time domain resource information is jointly indicated by a high-level configuration and a dynamic control signaling.

[0242] The time domain resource information of the i-th transmission implicitly indicates whether it crosses the slot boundary. Further, it is determined whether the time domain symbols corresponding to the i-th transmission opportunity and the previous transmission opportunity or the previous multiple transmission opportunities overlap in the time domain symbols. If there is overlap, it means that it crosses the slot boundary, otherwise it means that it does not cross the slot boundary.

[0243] For example, the SLIV1 of the first transmission opportunity indicates that the starting symbol is symbol #0, and the time domain duration is 8, that is, the time domain position is symbol #0 to symbol #8; the SLIV2 of the second transmission opportunity indicates that the starting symbol is symbol #9, and the time domain duration is 4, that is, the time domain position is symbol #9 to symbol #13, then these two transmission opportunities are in the same time slot, because there is no overlap between the two, and the total time domain length of the two transmission opportunities does not exceed the total length of one time slot.

[0244] If the SLIV2 indication starting symbol of the second transmission opportunity is symbol #4, and the time domain duration is 6, that is, the time domain position is symbol #4 to symbol #10, and there is a time domain overlap, then the two transmission opportunities are across the time slot boundary and are in different time slots.

[0245] Furthermore, the time slot index of the first transmission opportunity is determined by timing, wherein the timing refers to the timing of sending DCI from downlink to preparing PUSCH in uplink.

[0246] Method 4:

[0247] For any of the methods 1 to 3, a parameter is introduced. That is, a column is added to any of the tables in Table 1 to Table 2 to indicate the switching of the transmission scheme. For example, if the parameter is enabled or 1, it means that PUSCH is sent according to transmission scheme 1, and only the first group of SLIV is valid. If the parameter is not enabled or 0, it means that PUSCH is sent according to transmission scheme 2, and multiple groups of SLIV are valid, and vice versa.

[0248] Transmission scheme 1: An uplink grant schedules multiple PUSCH repetitions. The one or more repetitions may be in one time slot, or in a section of resources that can transmit uplink information in the same time slot, or in multiple consecutive available time slots. This transmission scheme is called mini-slot PUSCH repetitions. The uplink grant is obtained by any of the following methods: RRC signaling, or DCI. Furthermore, the section of resources that can transmit uplink information in the same time slot refers to a DL / UL switching point with more than one time slot, such as Fig.13 As shown, symbol #2 to symbol #7 are the first time domain resources in the time slot that can transmit uplink information, and symbol #10 to symbol #13 are the second time domain resources in the time slot that can transmit uplink information.

[0249] Transmission scheme 2: An uplink grant schedules multiple PUSCH transmissions. A segment of resources that can transmit uplink information in the same time slot can only have one PUSCH transmission, and multiple PUSCH transmissions can be made in multiple consecutive available time slots. This scheme is called multi-segment PUSCH. The uplink grant is obtained by any of the following methods: RRC signaling, or DCI. Furthermore, the segment of resources that can transmit uplink information in the same time slot refers to a segment of resources that can transmit uplink information in the same time slot that has more than one downlink / uplink DL / UL switching point in the time slot, such as Fig.13 As shown, symbol #2 to symbol #7 are the first time domain resources in the time slot that can transmit uplink information, and symbol #10 to symbol #13 are the second time domain resources in the time slot that can transmit uplink information.

[0250] Regardless of Mode 1 to Mode 4, for unscheduled PUSCH repeated transmission, when a transmission opportunity conflicts with the subframe format, the conflicting symbols are skipped and the available symbols corresponding to the transmission opportunity are divided into multiple consecutive repeated PUSCH transmissions. Fig.13 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 10 ,like Fig.13As shown, the time domain indication SLIV of the second transmission opportunity starts at symbol #8, L=6, but symbol #8 and symbol #9 conflict with the subframe format, so they are skipped. The second transmission opportunity starts transmission from symbol #10, and is divided into actual transmission opportunity #2 and actual transmission opportunity #3 across the time slot boundary, with a total length of 6 symbols.

[0251] Example 6

[0252] An uplink grant schedules multiple repeated transmissions of PUSCH, and the one or more repeated transmissions of PUSCH may be within one time slot, or may be on a section of resources that can transmit uplink information within the same time slot, or may be within multiple consecutive available time slots.

[0253] Fig.14 is a schematic diagram of sending a transmission block according to a preferred embodiment of the present application Figure 10 One, such as Fig.14 As shown, the uplink authorization scheduling is notified by RRC or activated by DCI, that is, when there is no scheduling transmission, only one set of time-frequency domain resources is configured for the transmission block, and multiple repetitions do not cross the period P, and the same period P corresponds to a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, referred to as HARQ) ID. PUSCH transmission can be started at any position on the available time domain symbols within the period P. Furthermore, the DMRS index of the first transmission opportunity and the remaining transmission opportunities are different. That is, the PUSCH carried on the first transmission opportunity uses DMRS i, and the PUSCH carried on the remaining transmission opportunities uses DMRS j.
