Description

Wireless communication method, terminal device and network device

Technical Field

The embodiments of the present application relate to the field of communications, and more particularly, to a wireless communication method, a terminal device, and a network device.

Background

For the time division duplex (Time Division Duplexing, TDD) spectrum, a transmission slot transmitting a physical uplink control channel (Physical Uplink Control Channel, PUCCH) repetition (repetition) determines N conditional slots according to a slot format configuration, where N is network configured.

In order to guarantee PUCCH transmission reliability, for PUCCH repetition, the relevant protocol convention must find N slots that meet the condition. This means that a longer PUCCH transmission delay may be caused. For example, for enhanced mobile Ultra wideband (Enhance Mobile Broadband, eMBB) traffic, the impact of PUCCH transmission delay is negligible, but for low latency high reliability communication (Ultra-Reliable and Low Latency Communication, URLLC) traffic, i.e. time delay sensitive traffic, PUCCH transmission delay, on the one hand the feedback delay of hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request-ACK, HARQ-ACK) exceeds the traffic delay, making HARQ-ACK a useless message, since it has not been possible to decide whether to trigger a retransmission based on HARQ-ACK information. On the other hand, due to lack of HARQ-ACK feedback, the HARQ process corresponding to the downlink data cannot be released, so that the transmission opportunity of other data is limited.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Fig. 1 is a schematic diagram of a communication system 100 according to an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that the present embodiments are illustrated by way of example only with respect to communication system 100, but the present embodiments are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), internet of things (Internet of Things, ioT) system, narrowband internet of things (Narrow Band Internet of Things, NB-IoT) system, enhanced Machine-type-Type Communications (eMTC) system, 5G communication system (also referred to as New Radio (NR) communication system), or future communication system, etc.

In the communication system 100 shown in fig. 1, the network device 120 may be an access network device in communication with the terminal device 110. The access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

Terminal device 110 may be any terminal device including, but not limited to, a terminal device that employs a wired or wireless connection with network device 120 or other terminal devices.

For example, the terminal device 110 may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment.

It should be understood that devices with communication functions in the network/system in the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functions, where the network device 120 and the terminal device 110 may be the devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

In addition, the term "indication" referred to in the embodiments of the present application may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B.

In addition, the term "corresponding" in the embodiments of the present application may mean that there is a direct correspondence or an indirect correspondence between the two, may mean that there is an association between the two, and may also mean that there is a relationship between an instruction and an instruction, an arrangement and an arrangement, or the like. The "predefined" or "predefined rule" mentioned in the embodiments of the present application may be implemented by pre-storing corresponding codes, tables or other manners that may be used to indicate relevant information in devices (including, for example, terminal devices and network devices), and the present application is not limited to the specific implementation manner thereof. Such as predefined may refer to what is defined in the protocol. It should also be understood that, in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in future communication systems, which are not limited in this application. In the embodiments of the present application, the terms "downlink" and "uplink" are used to indicate a transmission direction of a signal or data, where "downlink" is used to indicate that the transmission direction of the signal or data is a first direction sent from a station to a user equipment of a cell, and "uplink" is used to indicate that the transmission direction of the signal or data is a second direction sent from the user equipment of the cell to the station, for example, "downlink signal" indicates that the transmission direction of the signal is the first direction.

NR adopts a frame length of 10ms, and one frame contains 10 subframes. The 5 subframes form a half frame, and the subframes numbered 0 to 4 and the subframes numbered 5 to 9 are respectively located in different half frames.

The basic frame structure of the New air interface (NR) is in units of slots. Under a normal Cyclic Prefix (CP) configuration, each slot contains 14 symbols. Each slot contains 12 symbols in the extended CP case. The symbols in each slot can be divided into three categories: downlink symbols, uplink symbols, and flexible symbols. Depending on the actual scheduling of the base station, flexible symbols may be used for transmitting downlink data or uplink data, i.e. the transmission direction of the symbols is not fixed.

The NR frame structure configuration is flexibly configured by combining semi-static configuration of radio resource control (Radio Resource Control, RRC) signaling and dynamic configuration of downlink control information (Downlink Control Information, DCI). The RRC configuration supports both cell-specific RRC configuration and UE-specific RRC configuration. The manner of DCI configuration supports both direct indication by slot format indication (slot format indication, SFI) and DCI scheduling determination.

1. Semi-static frame structure configuration.

The NR system configures the frame structure based on periods, with only one downstream to upstream transition point in each period. So as to ensure continuous downlink resources and continuous uplink resources in each period. The frame structure period in Rel-15 may be 0.5ms,0.625ms,1ms,1.25ms,2ms,2.5ms,5ms,10ms.

2. Dynamic DCI configuration.

The dynamic DCI configuration frame structure may be implemented by DCI format 2_0 indicating SFI or by DCI format 0_0/0_1/0_2/1_0/1_1/1_2 scheduling uplink or downlink data transmission. The frame structure is not changed in a mode of scheduling data, but the transmission direction of the scheduled symbols is implicitly given by the transmission of the uplink or downlink data of DCI scheduling.

Typically, for a time division duplex (Time Division Duplexing, TDD) spectrum, a time slot transmitting a physical uplink control channel (Physical Uplink Control Channel, PUCCH) repetition determines N time slots meeting conditions from semi-statically configured uplink and flexible symbols, where N is network configured. Specific conditions may be:

the starting symbol of PUCCH is uplink symbol or flexible symbol except SS/PBCH symbol;

the number of symbols of consecutive uplink symbols or flexible symbols other than SS/PBCH symbols is equal to or greater than the number of symbols of the PUCCH, starting from the starting symbol of the PUCCH.

As shown in fig. 2, according to the timing relationship between PDSCH and PUCCH (DCI indication by scheduling PDSCH or semi-static configuration), it is determined that slots in which PUCCH repetition 1 and PUCCH repetition 2 are located are the 3 rd slot and the 4 th slot, respectively, but symbols of the 3 rd slot and the 4 th slot are all downlink symbols, that is, unavailable slots. Therefore, the PUCCH can be transmitted by continuing to look up until the symbols of the 8 th and 9 th slots are full uplink symbols, based on which the 8 th and 9 th slots can be determined as available slots for PUCCH repetition 1 and PUCCH repetition 2, respectively.

From the above, in order to guarantee PUCCH transmission reliability, N slots satisfying the condition must be found for PUCCH repetition. This means that a longer PUCCH transmission delay may be caused. For example, for enhanced mobile Ultra wideband (Enhance Mobile Broadband, eMBB) traffic, the impact of PUCCH transmission delay is negligible, but for low latency high reliability communication (Ultra-Reliable and Low Latency Communication, URLLC) traffic, i.e. time delay sensitive traffic, PUCCH transmission delay, on the one hand the feedback delay of hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request-ACK, HARQ-ACK) exceeds the traffic delay, making HARQ-ACK a useless message, since it has not been possible to decide whether to trigger a retransmission based on HARQ-ACK information. On the other hand, due to lack of HARQ-ACK feedback, the HARQ process corresponding to the downlink data cannot be released, so that the transmission opportunity of other data is limited.

Based on this, the present application provides a wireless communication method, by introducing a maximum threshold for delay of PUCCH repetition, and determining a transmission slot of the PUCCH repetition based on the maximum threshold, equivalently, restricting transmission of the PUCCH repetition by the maximum threshold, on one hand, normal transmission of the PUCCH repetition can be ensured, that is, it is ensured that a network side can timely decide whether retransmission occurs; on the other hand, the maximum threshold is used for restricting the repeated transmission of the PUCCH, so that the transmission of invalid information is avoided, and the system efficiency is improved.

Fig. 3 shows a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, which method 200 may be performed by a terminal device. Such as the terminal device shown in fig. 1.

As shown in fig. 3, the method 200 may include some or all of the following:

s210, acquiring a maximum threshold of the repetition delay of a Physical Uplink Control Channel (PUCCH);

s220, determining the time domain resource unit of the PUCCH repetition according to the maximum threshold.

In this embodiment, by introducing a maximum threshold for delay of PUCCH repetition, and determining a transmission slot of the PUCCH repetition based on the maximum threshold, equivalently, restricting transmission of the PUCCH repetition by the maximum threshold, on one hand, normal transmission of the PUCCH repetition can be ensured, that is, it is ensured that a network side can timely decide whether to initiate retransmission; on the other hand, the maximum threshold is used for restricting the repeated transmission of the PUCCH, so that the transmission of invalid information is avoided, and the system efficiency is improved.

In some embodiments, an interval between a position of the time domain resource unit of the PUCCH repetition and a position of the time domain resource unit of downlink data (e.g. PDSCH) corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and/or an interval between a position of the time domain resource unit of the PUCCH repetition and a position of the time domain resource unit of the PUCCH repetition determined by a timing relationship is less than or equal to the maximum threshold.

For example, an interval between a starting position of the time domain resource unit of the PUCCH repetition and a starting position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and/or an interval between a starting position of the time domain resource unit of the PUCCH repetition and a starting position of the time domain resource unit determined by the PUCCH repetition through a timing relationship is less than or equal to the maximum threshold. For another example, an interval between an end position of the time domain resource unit of the PUCCH repetition and an end position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and/or an interval between an end position of the time domain resource unit of the PUCCH repetition and an end position of the time domain resource unit determined by the PUCCH repetition through a timing relationship is less than or equal to the maximum threshold. For another example, an interval between a starting position of the time domain resource unit of the PUCCH repetition and an ending position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and/or an interval between the starting position of the time domain resource unit of the PUCCH repetition and the ending position of the time domain resource unit determined by the PUCCH repetition through a timing relationship is less than or equal to the maximum threshold. For another example, an interval between an end position of the time domain resource unit of the PUCCH repetition and a start position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition is less than or equal to the maximum threshold, and/or an interval between an end position of the time domain resource unit of the PUCCH repetition and a start position of the time domain resource unit determined by the PUCCH repetition through a timing relationship is less than or equal to the maximum threshold.

In other words, the maximum threshold in the embodiments of the present application may be used to limit the interval between the position of the time domain resource unit of the PUCCH repetition and the position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition, and may also be used to limit the interval between the position of the time domain resource unit of the PUCCH repetition and the position of the time domain resource unit determined by the timing relationship of the PUCCH repetition.

The timing relationship in the present application may refer to a timing relationship between the PDSCH and the PUCCH for feeding back the PDSCH. The DCI indication of PDSCH may be scheduled or semi-statically configured.

In some embodiments, the PUCCH is repeated for carrying uplink control information UCI; and/or, the PUCCH repetition includes a PUCCH carrying a hybrid automatic repeat request acknowledgement HARQ-ACK; and/or, the PUCCH repetition does not include a PUCCH carrying channel state information CSI.

In other words, the maximum threshold may be set independently for UCI. For example, there is a maximum threshold limit only for PUCCH repetition carrying HARQ-ACKs. Further, PUCCH repetition, which carries CSI, is not limited by a maximum threshold.

In some embodiments, the S210 may include:

receiving semi-static configuration information, wherein the semi-static configuration information comprises the maximum threshold;

And acquiring the maximum threshold according to the semi-static configuration information.

In some embodiments, the maximum threshold is configured independently by the PUCCH repetition corresponding semi-static configuration information.

In some embodiments, the semi-static configuration information may be higher layer signaling.

In some embodiments, the semi-static configuration information includes at least one of:

the physical downlink shared channel is configured with PDSCH-Config, SPS-Config, PUCCH-Config and PUCCH format configured with PUCCH-FormaConfig.

For example, PDSCH-Config, SPS-Config, PUCCH-Config, or PUCCH format configuration PUCCH-FormatConfig may be configured for the physical downlink shared channel independently. The maximum threshold may be configured independently in each SPS-Config for the case where multiple SPS-configs need to be configured.

In some embodiments, the S210 may include:

receiving indication information, wherein the indication information is used for indicating the maximum threshold;

and acquiring the maximum threshold according to the indication information.

In some embodiments, the indication information indicates the maximum threshold by at least one of:

An indication field in Downlink Control Information (DCI) repeatedly associated with the PUCCH;

a DCI format repeatedly associated with the PUCCH;

a search space in which DCI repeatedly associated with the PUCCH is located;

a control resource set (CORESEET) where DCI repeatedly associated with the PUCCH is located;

a CRC scrambling mode of DCI repeatedly associated with the PUCCH;

an RNTI employed when performing CRC scrambling on DCI associated with the PUCCH repetition;

an aggregation level of DCI associated with the PUCCH repetition; and

priority indication in DCI associated with the PUCCH repetition.

In other words, the maximum threshold may also be dynamically indicated. For example, the maximum threshold is indicated by adding an indication field to the DCI associated with the PUCCH repetition, or the maximum threshold is determined according to the DCI format associated with the PUCCH repetition, the search space or CORESET in which the DCI associated with the PUCCH repetition is located, the CRC scrambling method (e.g. RNTI used for CRC scrambling) of the DCI associated with the PUCCH repetition, the aggregation level of the DCI associated with the PUCCH repetition, and the priority indication in the DCI associated with the PUCCH repetition. Taking as an example the determination of the maximum threshold according to the priority indication in the DCI associated with PUCCH repetition. The first priority may be predefined or the network higher layer signaling may be configured to correspond to a first threshold and the second priority may be configured to correspond to a second threshold. And when the DCI received by the terminal indicates the first priority, determining the maximum threshold according to the first delay threshold by corresponding PUCCH repetition. And when the DCI received by the terminal indicates the second priority, the maximum threshold of the corresponding PUCCH repetition is the second threshold.

In some embodiments, the indication information is used to indicate the maximum threshold among a plurality of thresholds, the plurality of thresholds being configured by semi-static configuration information.

In other words, a plurality of thresholds may be semi-statically configured, with one of the values indicated dynamically being the maximum threshold. In one implementation, the plurality of thresholds are configured by PUCCH-Config, e.g., may be configured independently for each PUCCH-Config. The thresholds may be determined according to PUCCH-Config corresponding to PUCCH repetition, where PUCCH-Config corresponding to PUCCH repetition may be determined according to priority indicated by corresponding DCI or semi-statically configured priority. In another implementation, the multiple thresholds may be configured independently for PUCCH-FormatConfig (e.g., for each PUCCH format or PUCCH formats 1,3, and 4). And the thresholds are determined according to the PUCCH-Config corresponding to the PUCCH repetition. For example, the network side configures a threshold value of x1 for a first PUCCH format in the first PUCCH-Config and configures a threshold value of x2 for a second PUCCH format; and configuring a threshold value of x3 for the first PUCCH format in the second PUCCH-Config, and configuring a threshold value of x4 for the second PUCCH format. The terminal determines that the PUCCH-Config corresponding to the PUCCH repetition is the first PUCCH-Config according to the priority indication (such as high priority) in the DCI; in addition, determining that the adopted format is a first PUCCH format according to the PUCCH resources indicated in the DCI; the terminal may determine that the maximum threshold of PUCCH repetition corresponding to the current DCI is x1.

In some embodiments, the PUCCH repeated time domain resource unit includes N time domain resource units, and a first time domain resource unit of the N time domain resource units meets the requirement of the maximum threshold; or the time domain resource unit of the PUCCH repetition comprises a time domain resource unit meeting the requirement of the maximum threshold in N time domain resource units; or the time domain resource unit of the PUCCH repetition comprises N time domain resource units, and the last time domain resource unit in the N time domain resource units meets the requirement of the maximum threshold; or the PUCCH repetition is not expected to be transmitted and any one of the N time domain resource units does not meet the requirement of the maximum threshold.

Fig. 4 to 7 are examples of PUCCH repeated transmission slots provided in the embodiments of the present application. An implementation manner of determining the time domain resource unit of the PUCCH repetition according to the maximum threshold is described below by taking the time domain resource unit as an example in conjunction with fig. 4 to 7.

In some embodiments, the PUCCH repeated time domain resource unit includes N time domain resource units, and a first time domain resource unit of the N time domain resource units meets the requirement of the maximum threshold.

For example, as shown in fig. 4, the time domain resource units determined by the PUCCH repetition 1 and PUCCH repetition 2 through the timing relationship are the 3 rd slot and the 4 th slot, the available time domain resource units determined by the PUCCH repetition 1 and PUCCH repetition 2 through the slot format configuration are the 6 th slot and the 9 th slot, and the maximum threshold is 6 slots. Since the 6 th time slot where the PUCCH repetition 1 is located is earlier than the end position of the maximum threshold, that is, the 6 th time slot where the PUCCH repetition 1 is located meets the requirement of the maximum threshold, the PUCCH repetition 1 and the PUCCH repetition 2 may be transmitted on the 6 th time slot and the 9 th time slot, respectively. In other words, since the interval between PUCCH repetition 1 and PDSCH is less than or equal to 6 slots, i.e. the 6 th slot in which PUCCH repetition 1 is located meets the requirement of the maximum threshold, PUCCH repetition 1 and PUCCH repetition 2 may be transmitted on the 6 th slot and 9 th slot, respectively.

In this embodiment, by ensuring that normal transmission meets at least part of PUCCH repetition required by the maximum threshold, it is further ensured that the network side can timely decide whether to initiate retransmission. In addition, by transmitting at least part of PUCCH repetition that does not meet the requirement of the maximum threshold, the reliability of UCI transmission carried in PUCCH can be ensured.

In some embodiments, the PUCCH repeated time domain resource unit includes a time domain resource unit satisfying the requirement of the maximum threshold from among N time domain resource units.

For example, as shown in fig. 5, the time domain resource units determined by the PUCCH repetition 1 and PUCCH repetition 2 through the timing relationship are the 3 rd slot and the 4 th slot, the available time domain resource units determined by the PUCCH repetition 1 and PUCCH repetition 2 through the slot format configuration are the 6 th slot and the 9 th slot, and the maximum threshold is 6 slots. Since the 6 th time slot of the PUCCH repetition 1 is earlier than the end position of the maximum threshold, namely the 6 th time slot of the PUCCH repetition 1 meets the requirement of the maximum threshold; the 9 th time slot of the PUCCH repetition 2 is later than the end position of the maximum threshold, namely the 9 th time slot of the PUCCH repetition 2 does not meet the requirement of the maximum threshold; therefore, PUCCH repetition 1 may be transmitted only on the 6 th slot. In other words, since the interval between the slot in which PUCCH repetition 1 is located and PDSCH is less than or equal to 6 slots, and the interval between the slot in which PUCCH repetition 2 is located and PDSCH is greater than 6 slots, PUCCH repetition 1 may be transmitted only on the 6 th slot.

In this embodiment, by ensuring that normal transmission meets at least part of PUCCH repetition required by the maximum threshold, it is further ensured that the network side can timely decide whether to initiate retransmission. In addition, since the PUCCH repetition reception after the maximum threshold no longer plays a role in the subsequent data retransmission decision, by restricting at least part of PUCCH repetition that does not meet the requirement of the maximum threshold, that is, transmitting only at least part of PUCCH repetition that meets the requirement of the maximum threshold, invalid information transmission can be avoided, and system efficiency can be improved.

In some embodiments, the PUCCH repeated time domain resource unit includes N time domain resource units, and a last time domain resource unit of the N time domain resource units meets the requirement of the maximum threshold.

For example, as shown in fig. 6, the time domain resource units determined by the timing relationship of PUCCH repetition 1 and PUCCH repetition 2 are the 3 rd slot and 4 th slot, respectively, the available time domain resource units determined by the slot format configuration of PUCCH repetition 1 and PUCCH repetition 2 are the 6 th slot and 7 th slot, respectively, and the maximum threshold is 6 slots. Since the last slot of the 6 th and 7 th slots is before the end of the maximum threshold, PUCCH repetition 1 and PUCCH repetition 2 may be transmitted on the 6 th and 7 th slots, respectively. In other words, since the interval between the last slot of the 6 th slot and the 7 th slot and the PDSCH is less than or equal to 6 slots, that is, the 7 th slot where the PUCCH repetition 2 is located meets the requirement of the maximum threshold, the PUCCH repetition 1 and the PUCCH repetition 2 may be transmitted on the 6 th slot and the 7 th slot, respectively.

In this embodiment, through the transmission of the maximum threshold constraint PUCCH repetition, not only can the timely transmission of the effective PUCCH repetition and the reliability of the transmission be ensured, but also the network side can timely decide whether to initiate retransmission, and can also avoid invalid information transmission, thereby improving the system efficiency.

In some embodiments, the PUCCH repetition is not expected to be transmitted and any one of the N time domain resource units does not meet the requirement of the maximum threshold.

For example, as shown in fig. 7, the time domain resource units determined by the timing relationship of PUCCH repetition 1 and PUCCH repetition 2 are the 3 rd slot and 4 th slot, respectively, the available time domain resource units determined by the slot format configuration of PUCCH repetition 1 and PUCCH repetition 2 are the 6 th slot and 9 th slot, respectively, and the maximum threshold is 6 slots. Since the last slot of the 6 th slot and the 9 th slot is after the end of the maximum threshold, the terminal device does not expect to transmit PUCCH repetition 1 and PUCCH repetition 2, or the slots of PUCCH repetition 1 and PUCCH repetition 2 are empty. In other words, since the interval between the last slot of the 6 th slot and the 9 th slot and the PDSCH is greater than 6 slots, the terminal device does not expect to transmit PUCCH repetition 1 and PUCCH repetition 2, or, the slots of PUCCH repetition 1 and PUCCH repetition 2 are empty.

In some embodiments, the N time domain resource units are time domain resource units determined according to a slot format configuration that are available for transmitting the PUCCH repetition. The slot format configuration may be a semi-static frame structure configuration or a dynamic DCI configuration. The slot format configuration includes configured uplink and flexible symbols.

In other words, the terminal device may determine a time domain resource unit of the PUCCH repetition from among time domain resource units available for transmission of the PUCCH repetition determined according to the slot format configuration based on the maximum threshold. For example, the N time domain resource units may be used as a first temporary time domain resource unit set of the PUCCH repetition, and the terminal device may determine the time domain resource unit of the PUCCH repetition in the first temporary time domain resource unit set based on the maximum threshold. In other words, the terminal device may determine a first temporary time domain resource unit set of the PUCCH repetition according to the slot format configuration, and then determine a time domain resource unit of the PUCCH repetition in the first temporary time domain resource unit set based on the maximum threshold.

In some embodiments, the N time domain resource units may be determined from semi-statically configured uplink and flexible symbols.

In one implementation, the conditions satisfied by the N time domain resource units may include:

the starting symbol of PUCCH is uplink symbol or flexible symbol except SS/PBCH symbol; and is also provided with

the starting symbol of PUCCH is uplink symbol or flexible symbol except SS/PBCH and CORESET 0 symbol; and is also provided with

Of course, in other alternative embodiments of the present application, the N time domain resource units may also be determined according to a dynamic SFI indication. For example, the conditions satisfied by the N time domain resource units may include: the starting symbol of the PUCCH is a semi-statically determined uplink symbol or a dynamically indicated uplink symbol; and the number of symbols of continuous semi-statically determined uplink symbols or dynamically indicated uplink symbols with the starting symbol of the PUCCH as the starting point is greater than or equal to the number of symbols of the PUCCH.

In some embodiments, the N is a number of repetitions of the PUCCH repetition, the number of repetitions being greater than or equal to 1.

In some embodiments, the N is configured by a network device.

In some embodiments, the S220 may include:

and determining the time domain resource unit of the PUCCH repetition based on a preset rule and the maximum threshold.

In some embodiments, the preset rules include:

the PUCCH repeated time domain resource unit is located before at least one of the following time domain resource units:

a time domain resource unit in which other uplink channels (for example, other PUCCHs or PUSCHs except the PUCCH corresponding to the PUCCH repetition) exist after the PUCCH repetition and uplink transmissions collide;

a time domain resource unit of the target downlink data after the PUCCH repetition, wherein the HARQ process of the target downlink data is the same as the HARQ process of the downlink data corresponding to the PUCCH repetition; and

a first time domain resource unit where an uplink channel corresponding to the (n+1) th SPS PDSCH is located; the downlink data corresponding to the repetition of the PUCCH is an nth SPS PDSCH, and the position of the first time domain resource unit is determined according to a timing relationship, or the position of the first time domain resource unit is determined according to the timing relationship and a slot format configuration.

In other words, on the one hand, the time domain resource unit of PUCCH repetition is not only to satisfy: the interval between the position of the time domain resource unit of the PUCCH repetition and the position of the time domain resource unit of the downlink data corresponding to the PUCCH repetition is smaller than or equal to the maximum threshold, and/or the interval between the position of the time domain resource unit of the PUCCH repetition and the position of the time domain resource unit of the PUCCH repetition determined by the timing relationship is smaller than or equal to the maximum threshold. On the other hand, the time domain resource unit of PUCCH repetition also needs to satisfy: the PUCCH repeated time domain resource unit is located before at least one of the following time domain resource units: time domain resource units with other uplink channels and uplink transmission conflicts exist after the PUCCH is repeated; a time domain resource unit of the target downlink data after the PUCCH repetition, wherein the HARQ process of the target downlink data is the same as the HARQ process of the downlink data corresponding to the PUCCH repetition; and a first time domain resource unit in which an uplink channel corresponding to the (n+1) th SPS PDSCH is located; the downlink data corresponding to the repetition of the PUCCH is an nth SPS PDSCH, and the position of the first time domain resource unit is determined according to a timing relationship, or the position of the first time domain resource unit is determined according to the timing relationship and a slot format configuration.

Of course, in other alternative embodiments of the present application, the preset rule may also be that the time domain resource unit of the PUCCH repetition is located before other time domain units that meet certain conditions, which is not specifically limited in the present application.

In some embodiments, the method 100 may further comprise:

and transmitting part or all of the PUCCH in the PUCCH repetition on the time domain resource unit of the PUCCH repetition.

In some embodiments, the time domain resource units are time slots or sub-time slots.
