Description

Field of technology to which the invention relates

The present application relates to the field of communication technology and, in particular, to a communication method and a communication device.

State of the art

In today's new radio (NR) communication system, time domain resources for a data channel may be predefined using some protocol and/or designated dynamically using higher layer signaling. Such dynamic indication using higher layer signaling may be that after the terminal device and the base station establish a Radio Resource Control (RRC) connection with each other, the base station configures a set of time domain resources (e.g., a time domain resource table) for a terminal device using RRC control signaling. Currently, a base station may configure a terminal device using RRC control signaling with a set of time domain resources corresponding to some special format. For example, the base station may configure a first time domain resource table in DCI format 0_1 (hereinafter referred to as DCI format) and a second time domain resource table in DCI format 0_2. However, the time domain resources corresponding to some rows in the time domain resource table may not be applicable to DCI information in some special downlink control information (DCI) format. For example, when DCI format 0_1 or DCI format 1_1 is configured using a slot-level time domain repetition method, some slot boundary-crossing time domain resources in the time domain resource table may not be suitable for use. In view of this, it is necessary to establish a mechanism to ensure that the terminal device and the base station select the correct time domain resources for data transmission.

Embodiments of the present application provide a communication method and a communication device for implementing a time domain resource determination method to improve the reliability of communication between a terminal device and a network device.

According to a first aspect, a communication method is proposed, and the method can be implemented by a terminal device. The method comprises: determining, by a terminal device, at least one set of temporary domain resources, where each of the plurality of the at least one set of temporary domain resources corresponds to one DCI format. The terminal device then determines a third set of temporary domain resources for grant-free scheduling based on said set of at least one set of temporary domain resources, and the terminal device determines a third temporary domain resource from said third set of temporary domain resources, and then transmits the uplink data to the network device using the resulting third time domain resource, or receives downlink data using the third time domain resource.

In this embodiment of the present application, the network device and the end device determine a set of temporary domain resources using the same rule, so that the sets of temporary domain resources found by the network device and the end device can be assured to be consistent, thereby ensuring that the same ones are selected. and the same data transmission resources and ensuring normal communication. In addition, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting the time domain resource sets with the same repetition method can provide one time domain repetition method and ensure that all The time domain resources in the considered time domain resource sets may conform to the characteristics of this time domain repetition method, thereby providing assurance of normal communication.

In one embodiment, the at least one temporary domain resource set is only one temporary domain resource set and is a first temporary domain resource set corresponding to the first DCI format. The terminal device may further receive first indication information from the network device, where the first indication information is used to indicate a time domain recurrence method with grant-free scheduling. The terminal device determines a third set of temporary domain resources for grant-free scheduling based on a time-domain iteration method with grant-free scheduling and the specified at least one set of temporary domain resources. For example, the base station transmits first indication information to the terminal device, and this first indication information is used to inform the terminal device that the corresponding time domain repetition method is a slot-level time domain repetition method. In this case, the terminal device can determine, based on the first indication information, a time domain resource corresponding to a time domain repetition method at the slot level. This method is relatively simple and straightforward.

In one embodiment, in addition to transmitting the first direction information to the terminal device, the network device may transmit second direction information to the terminal device. The second indication information is used to indicate a time domain repetition method when using the first DCI format (ie, for the first DCI format), and is used to indicate a time domain repetition method when using the second DCI format (ie, for second DCI format). Then, upon determining that the time domain repetition method with grant-free scheduling, the time domain repetition method for the first DCI format, and the repetition method for the second DCI format satisfy Rule 1, the terminal device determines that the specified at least one set Time Domain Resources is a third set of time domain resources for non-grant planning. Rule 1: The time domain retry method with non-grant scheduling, the time domain retry method for the first DCI format, and the retry method for the second DCI format are all the same or all different, and there is no set of time domain resources specific to the second DCI -format.

Carrying out the invention

For clarity of the objectives, technical solutions and advantages of the embodiments of the present application, the embodiments of the present application are further described in more detail with reference to the accompanying drawings.

The following describes certain terms used in embodiments of the present application to facilitate its understanding by those skilled in the art.

(1) A terminal device is a device that provides a user with a voice and/or data connection, for example it may comprise a hand-held device having a wireless (radio) connection function, or a processing device connected to a wireless (radio) modem. The end device can communicate with the core communications network via a radio access network (RAN) and exchange voice and/or data messages with the RAN. The terminal device may be a user equipment, terminal device, a wireless terminal device, a mobile terminal device, a subscriber unit, a subscriber station, a mobile station, a mobile console, remote station, access point (AP), remote terminal device, access terminal device, user terminal device, user agent device, user user device or other similar device. For example, the terminal device may be a mobile telephone (also referred to as a "cellular" telephone), a computer having a mobile terminal device that is portable, handheld, hand-held, or built into a computer, or a mobile device mounted on a vehicle, or a smart wearable device. For example, a terminal device is a device such as a personal communication service (PCS) telephone, a cordless telephone, a session initiation protocol (SIP) telephone, or a wireless local loop station (local radio). wireless local loop (WLL) or personal digital assistant (PDA). The terminal device may further be a device with limited functionality, such as a device with limited power consumption, a device with limited storage capabilities, or a device with limited computing capabilities. For example, the terminal device may be or contain an information reader such as a bar code scanner, radio frequency identification (RFID) reader, sensor, global positioning system (GPS) device, or laser scanner.

By way of example, and not limitation, in various embodiments of this application, the terminal device may alternatively be a wearable device. A wearable device may also be referred to as a wearable smart device, and it is a general term for wearable devices such as glasses, gloves, wristwatches, clothing and shoes, designed using wearable technology in smart variants for everyday wear. A wearable device is a portable device that can be worn directly on the body or integrated into the wearer's clothing or accessory. A wearable device is not just a piece of hardware, but is also used to implement powerful functions through the use of software support, data interaction or cloud interaction. Broadly speaking, wearable smart devices include both full-featured and relatively large-sized devices that can implement some or all of their functions independently of smartphones, such as smart wristwatches or smart glasses, as well as devices that focus on the functionality of only one type of application and should work with other devices such as smartphones, such as a variety of smart bracelets, smart helmets or smart jewelry to monitor physical characteristics.

(2) The network device is, for example, an access network (AN) device such as a base station (such as an access point), and may be a device that resides in the access network and communicates with a wireless (radio) endpoint device via a radio interface within one or more cells. A network device may be configured to: convert a received radio frame and an Internet protocol (IP) data packet, and to serve as a router between the end device and the rest of the access network, where the rest of the access network may contain an IP network. The network device may further coordinate control of the radio interface attributes. For example, a network device may contain an evolved NodeB (NodeB or eNB or e-NodeB, evolved NodeB) in a long term evolution (LTE) system or in an advanced LTE system (LTE-Advanced, LTE-A), may contain a NodeB node of the next generation (next generation NodeB, gNB) in the fifth generation (5G) communication system “New radio” (NR), or may contain a centralized unit (CU) and a distributed module (distributed unit, DU) in the cloud radio access network (CloudRAN). The embodiments of this application are not limited to this.

(3) Enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency Communication (URLC) are three typical services 5G systems in the future. As one of the typical services of 5G systems, URLLC communication is applied to scenarios such as self-driving and telemedicine (providing medical care at a distance), which have more stringent requirements for reliability and latency.

(4) The terms “system” and “communications network” may be used interchangeably in embodiments of this application. The term "several of" means two or more than two. Accordingly, in embodiments of the present application, the term “several of” may also be understood as “at least two.” The term "at least one" can be understood as one or more, such as one, two or more. For example, “including at least one” means “including one, two or more”, and whether one, two or more is included is not limited. For example, if at least one of A, B, and C is indicated to be included, A, B, C, A and B, A and C, B and C, or A, B, and C may actually be included. The term " and/or" describes the relationship of association between associated objects and represents that three relationships can exist. For example, A and/or B can represent three cases: There is only A, there are both A and B, and there is only B. In addition to this, the "/" symbol typically indicates an "or" relationship between associated objects unless specifically stated other.

Unless specifically stated otherwise, serial numbers such as “first” and “second” referred to in embodiments of this application are used to distinguish between multiple entities and are not used to limit the sequence, temporal order, priorities, or importance of those multiple entities.

Embodiments of the present application can be applied to a variety of communication systems, for example, they can be applied to a Narrowband Internet of Things (NB-IoT) system, Internet of Things (IoT) system, MTC communication system, eMTC communication system, LTE system, LTE-A system , the New Radio (NR) system, or any new communication system that will be developed in the future. The communication method proposed in embodiments of the present application may be used under the assumption that an entity in a communication system uses different spreading sequences at different times to achieve the goal of interference randomization.

In FIG. 1 illustrates a communications system to which embodiments of the present application may be applied. The communication system shown in FIG. 1, contains a network device and six terminal devices. Any of these devices from endpoint device 1 to endpoint device 6, inclusive, can transmit uplink data to the network device. In addition, devices from terminal device 4 to terminal device 6, inclusive, may form a communication subsystem. The network device may transmit downlink information to terminal device 1, terminal device 2, terminal device 3, and terminal device 5. The terminal device 5 can transmit downlink information to the terminal device 4 and the terminal device 6 based on device-to-device (D2D) communication technology. In FIG. 1 is just a simplified diagram, and the type of communication system, the number of devices included in the communication system, the types of devices used in the communication system and other similar characteristics are not limited in any way.

The communications network architecture and service scenario discussed in the embodiments of this application are intended to more clearly describe the technical solutions of the embodiments of this application and do not constitute limitations on those technical solutions proposed by the embodiments of this application. Even a person skilled in the art can appreciate that: As communications network architectures evolve and new service scenarios emerge, the technical solutions provided by the embodiments of this application also remain applicable to similar technical problems.

The following explains and describes certain communications concepts or terms used in this application. These concepts and terms from the field of communication are also used as part of the content of the invention according to the present application.

1. Slot: A slot is a unit in the time domain for scheduling data transmission. In the regular cyclic prefix option, one slot contains 14 characters. In the extended cyclic prefix option, one slot contains 12 characters.

2. Higher Layer Signaling: Higher Layer Signaling may be signaling carried by a higher layer protocol layer. This higher layer protocol layer is at least one protocol layer above the physical layer. This higher-level protocol layer may, in particular, be at least one of the following protocol layers: a medium access control (MAC) layer, a radio link control (RLC) layer, a packet convergence protocol layer data (packet data convergence protocol, PDCP), radio resource control (RRC) layer and non-access stratum (NAS).

3. New DCI format: For example, a new DCI format may be a compact DCI format, in other words, a downlink control information (DCI) format with a relatively small number of bits, and be a new DCI format that designed for data planning and which is introduced in the NR R16 standard. Since the number of bits is flexibly configured, for example, a relatively small number of bits can be configured, this new DCI format can be used as a DCI format for scheduling a high reliability service. The compact DCI format for scheduling uplink data may be referred to as DCI format 0_2 (or DCI format 0_2), and the compact DCI format for scheduling downlink data may be referred to as DCI format 1_2 (or DCI format 1_2).

4. Recovery DCI Format: Recovery DCI format is applicable as the DCI format used before establishing an RRC control connection or in the process of reconfiguring an RRC control connection. The recovery DCI format for scheduling uplink data may be referred to as DCI format 0_0 (or DCI format 0_0). The recovery DCI format for scheduling downlink data may be referred to as DCI format 1_0 (or DCI format 1_0). Each field of the DCI recovery format is not associated with configuration information to avoid ambiguity during the reconfiguration process.

5. Normal DCI Format: Normal DCI Format is a DCI format introduced in the NR R15 standard for data scheduling. The normal DCI format for scheduling uplink data may be called DCI format 0_1 (or DCI format 0_1). The normal DCI format for downlink data scheduling may be called DCI format 1_1 or DCI format 1_1).

6. Time Domain Resource Set: A time domain resource set may be a set of time domain resources predefined by the protocol, or may be a set of time domain resources configured at a higher level. A collection of temporary domain resources may be represented in a table or other form. For example, the structure of the time domain resource table (uplink table and downlink table are separate) preset in the protocol is shown in Table. 1.

Table 1

Row index (line number) Channel display type PUSCH/PDSCH K2/K1 S (symbol) L (length) 1 Type A x x x 2 Type A x x x 3 Type A x x x ... ... ... ... ... 16 Type B x x x

The symbol S represents the start symbol of the data channel, and the symbol L represents the number of symbols occupied by this data channel (the number of consecutive symbols starting with the symbol S). The K2 parameter (the table for the uplink contains the K2 parameter) denotes the number of slots between the time the PDCCH is received and the time the PUSCH is transmitted. The K0 parameter (the downlink table contains the K0 parameter) denotes the number of slots between the time the PDCCH is received and the time the PDSCH is transmitted. The PDSCH/PUSCH channel mapping type has two candidates: Type A and Type B. Type A indicates that the position of the first demodulation reference signal (DMRS) is in the third symbol or fourth symbol in the slot. Type B indicates that the position of the first DMRS signal is at the first symbol at the beginning of the data channel.

The structure of the time domain resource table (the table for the uplink and the table for the downlink are separate) configured by the base station for the user using higher layer signaling (eg, RRC control signaling) is shown in Table. 2.

table 2

Channel display type PUSCH/PDSCH K2/K1 SLIV Type A x x Type A x x Type A x x ... ... ... Type B x x

A temporary domain resource table configured as shown in Table. 2 has a maximum of 16 lines, and the SLIV parameter in this Table. 2 is the result obtained by encoding the S and L parameters together. A single SLIV parameter can uniquely define a group of S and L parameters. Refer to the above description for the corresponding explanations regarding the K2 parameter or the K0 parameter and the PUSCH channel mapping type.

7. Grant based (GB) scheduling method: The GB grant scheduling method is a data scheduling method in which the base station transmits control information (eg, PDCCH) to the terminal device, and this PDCCH is used to schedule data transmission. downlink (eg, PDSCH) or uplink data transmission scheduling (eg, PUSCH). In other words, the PDCCH indicates a time domain resource for a PDSCH or a PUSCH. In the following, the time domain resource indication for the PUSCH is used as an example to describe today's time domain resource indication procedure.

Step 1: The base station determines a set of time domain resources, where the set of time domain resources may be a set of time domain resources predefined in the protocol or a set of time domain resources configured by a higher layer. (The specific forms of the protocol-predefined table and the higher-level configured table are shown here as Table 1 and Table 2.)

For a received PDCCH, the terminal specifically uses any one of the following rules to determine the set of time domain resources corresponding to the DCI information transmitted on the PDCCH:

Rule 1: Determine the set of temporary domain resources corresponding to the DCI information according to the rule described in the following Table. 3, if the DCI information transmitted on the PDCCH is scrambled using a cell radio network temporary identifier (C-RNTI), MCS-C-RNTI, Temporary Cell Radio Network Temporary Identity (TC) -RNTI) or a configured scheduling RNTI (CS-RNTI), a specified physical downlink control channel (PDCCH) is received in the common search space (CSS), and a control resource set ( The CORESET associated with the search space is not CORESET 0 (in this case, the DCI information is by definition DCI recovery information, since only DCI recovery information can be received in the CSS space).

Table 3

A set of temporary domain resources specified by system information A set of temporary domain resources specific to an endpoint A set of temporary domain resources corresponding to DCI information Does not exist Does not exist Default set of time domain resources in a protocol Exists Exists A set of temporary domain resources specified by system information Exists or doesn't exist Exists A set of temporary domain resources specific to an endpoint

Table 3 has the following meaning: The terminal device determines whether the network device has transmitted hint information X, where this hint information may be carried in higher layer signaling and may be designated as a push-TimeDomainAllocationList. The X indication information indicates a set of temporary domain resources specific to the terminal device. When the time-domain resource set is an end-device-specific time-domain resource set, the end-device-specific time-domain resource set may be used for all DCI information for the end device.

If a terminal device-specific temporary domain resource set has the status "Exists," that is, the network device transmits indication information to indicate that the terminal device has a specific terminal device-specific temporary domain resource set, the terminal device-specific temporary domain resource set is a set of time domain resources corresponding to DCI information.

If the target device-specific temporary domain resource set has a status of "Does Not Exist," in other words, the network device does not transmit indication information indicating the terminal device-specific temporary domain resource set, the terminal device determines whether the temporary domain resource set is designated by the system information.

Further, if there is a set of temporary domain resources indicated by the system information, in other words, the network device transmits a set of temporary domain resources indicated by the system information, this set of temporary domain resources indicated by the system information is used as a set of temporary domain resources corresponding to the DCI information.

Further, if the system information does not specify a time domain resource set, then the default time domain resource set in the protocol is used as the time domain resource set corresponding to the DCI information.

Rule 2: Determine the set of time domain resources corresponding to the DCI information in the manner illustrated in Table. 3, if the DCI information transmitted on the PDCCH is scrambled using the C-RNTI, MCS-C-RNTI, TC-RNTI or CS-RNTI, and the PDCCH is received in a user-specific search space (terminal device- specific search space (USS) (for example, the DCI information may be DCI recovery information or normal DCI information).

Step 2: The terminal device receives a PDCCH, where this PDCCH carries DCI information, and this DCI information contains X bits that indicate a string in the determined set of time domain resources to indicate the start symbol S and the length L of the data channel.

If the format of the DCI information corresponds to the DCI recovery information, that is, is DCI format 1_0 (used for scheduling downlink data) or DCI format 0_0 (used for scheduling uplink data), X is 4 bits. In other words, four bits are used to indicate which row in the time domain resource table corresponds to the time domain resource being searched.

If the format of the DCI information corresponds to normal DCI information, that is, is DCI format 1_1 (used for downlink data scheduling) or DCI format 0_1, the number of X bits depends on the size of the table. If the table contains 16 rows, 4 bits are used; or if the table contains 8 rows, 3 bits are used.

8. Grant free (GF) scheduling method: The grant free (GF) method is a data scheduling method and may be called a configured grant type 1 method or a CG grant type 1 method. According to this method, the base station does not transmits control information, in other words, a PDCCH, to the user (which is also called a grant-free scheduling method or a configured scheduling method), and the location of a time domain resource occupied for data transmission is configured using higher layer signaling. The following specifically describes the procedure for indicating a time domain resource in today's non-grant (GF) process.

Step 1: The base station defines a set of time domain resources, where the time domain resource table may be a table predefined in the protocol or a table configured through a higher layer (for more details regarding table contents, please refer to the above description and here details will not be described again).

The specific rule for determining the set of time domain resources is given in the description of “Rule 2” in the “Grant Based Planning Method” discussed above. The details will not be repeated here.

Step 2: The base station transmits a higher layer signaling to the terminal device, where the higher layer signaling designates a string in the resulting set of time domain resources to indicate the start symbol S and the length L of the data channel.

According to the above method steps, the user can determine the start symbol and the number of symbols for the time domain resource in the data channel. For example, the user may specify that S = 2 and L = 4. In other words, the starting symbol of the data channel is 2, and the length of the channel is 4, as shown in FIG. 2A.

In addition, the R15 standard supports slot-level repetition. Specifically, the base station further configures an aggregation factor (aggregationFactorDL) for the user. This coefficient is denoted as K, and this coefficient K represents the number of consecutive slots used for data transmission. If this factor is not configured, it is assumed that there is no repetition. For example, the user determines that the start symbol in the data channel is symbol 2, the length is 4, and the aggregation factor is 2, which means that data is transmitted in two consecutive slots, the start symbol of the data in each slot is symbol 2, and the length of the data in each slot is 4, as shown in FIG. 2B.

In the NR R16 standard, in other words, in the 16th version, improvements to the time domain resource indication contain:

Extension 1: There are two time domain repetition methods: a mini-slot time domain repetition method and a slot-based time domain repetition method.

The first type: supports repetitions at the mini-slot level (also called PUSCH transmission scheme according to the Rel-16 standard).

(1) Specifically, the base station indicates one time domain resource and then indicates a repetition number R, in other words, R resources are obtained by repeating the first time domain resource R consecutive times. If a resource crosses a slot boundary, that resource is split into two resources.

For example, it is specified that the starting symbol of a temporary domain resource is symbol 12, the length is four symbols, and the repetition number is 2. In other words, the first resource occupies from symbol 12 to symbol 1 in the second slot. And the second resource occupies from character 2 to character 5 in the second slot. Since the first resource crosses a slot boundary, this first resource can be split into two resources using the slot boundary, in other words, there are three repetitions, and the resources occupied by these three repetitions are shown in FIG. 2C. With this approach, even if the data is at a slot boundary, the data can still be repeated without waiting for the next slot, thus ensuring low latency and high reliability.

(2) Since data can start with any character, this time domain repetition method can only support mapping type B.

(3) In addition, only normal DCI information or compact DCI information can be used for scheduling the mini-slot-based time domain repetition method, and DCI recovery information cannot be used for scheduling the mini-slot-based time-domain repetition method. .

(4) Repetition number indication: A special method for mini-slot repetition indication is to add a column to the time domain resource table configured by a higher level to indicate the repetition number, as shown in Table. 4.

Table 4

PUSCH/PDSCH display method K2/K1 SLIV
or S/L Number of repetitions, R x x x x x x x x x x x x ... ... ... ... x x x x

Second type: supports slot-level repetitions (also called PUSCH transmission scheme according to the Rel-15 standard).

A special way to indicate the number of repetitions is to add a column to the time domain resource table configured by the higher level, where the column indicates the number of repetitions. Alternatively, the table is configured at a higher level similar to the R15 standard, but the column is not added. The number of repetitions is indicated by an additional higher level signaling segment.

Extension 2: For grant-based (GB) scheduling, the base station can configure which time domain repetition method is used for the DCI format, in other words, normal DCI information or compact DCI information. For example, a slot-based time domain repetition method is configured for normal DCI information, and a mini-slot-based time domain repetition method is configured for compact DCI information. For grant-free (GF) scheduling, the time domain recurrence method is configured by a higher layer.

Based on the above analysis, in the known art, the base station can configure different time domain resource tables for different DCI formats using higher layer signaling. Let us assume that the base station configures two time domain resource tables, for example, a time domain resource table corresponding to the normal DCI format and a time domain resource table corresponding to the compact DCI format. In this case, for the Grant-Free (GF) scheduling scenario, a principle is needed for the terminal and base station to define the appropriate time domain resource tables in the Grant-Free (GF) scenario in such a way as to ensure consistency between the base station and the user.

In view of this, one embodiment of the present application proposes a simplified logic diagram of the first communication method, as shown in FIG. 3. This method is applicable for the non-grant (GF) scheduling scenario and can be implemented by the endpoint. As shown in FIG. 3, the method contains the following steps.

Step 301: The terminal device determines at least one set of temporary domain resources, where each of the plurality of the at least one set of temporary domain resources corresponds to one DCI format.

The at least one set of time domain resources may be configured using higher layer signaling, or may be predefined in a protocol. The set of temporary domain resources may be, for example, in the form of a temporary domain resource table shown in Table. 1, Table. 2 or Table. 3, or may be in some other form. This is not limited in this application.

In one embodiment, the at least one set of temporary domain resources may be only one set of temporary domain resources, or it may be two sets of temporary domain resources, or a collection called the at least one set of temporary domain resources may contain three or more sets of temporary domain resources. When such at least one temporary domain resource set is a combination of two temporary domain resource sets, the two temporary domain resource sets may be a first temporary domain resource set corresponding to a first DCI format and a second temporary domain resource set corresponding to a second DCI format. format. It should be noted that the first DCI format in the following can be understood as a normal DCI format (or understood as DCI format 0_1 or DCI format 1_1), and the second DCI format can be understood as a compact DCI format (or understood as DCI- format 0_2 or DCI format 1_2). The third DCI format can be understood as a recovery DCI format or understood as DCI format 0_0 or DCI format 1_0).

Step 302: The terminal device determines a third set of temporary domain resources for grant-free scheduling based on the at least one set of temporary domain resources.

In particular, the terminal device may determine a third set of time domain resources for grant-free scheduling based on information such as an indication of the time domain repetition method and DCI format for the at least one set of time domain resources under consideration in accordance with a pre-negotiated rule. Information about the specific rule is provided below.

Step 303: The terminal device determines a third temporary domain resource from a third set of temporary domain resources.

Step 304: The terminal device transmits uplink data to the network device using a third time domain resource, or receives downlink data using a third time domain resource.

The following will discuss various cases of determining a third set of temporary domain resources at step 302 in the embodiment shown in FIG. 3.

Case 1: The at least one temporary domain resource set is exactly one temporary domain resource set and is the first temporary domain resource set corresponding to the first DCI format.

The terminal device determines a temporary domain resource corresponding to the first DCI format as follows.

Method 1: The terminal device receives X indication information from the network device, where this X indication information indicates a set of time domain resources specific to the first DCI format, in other words, a first set of time domain resources. This guidance information can be conveyed in higher layer signaling. For example, the X indication information can be designated as pusch-TimeDomainAllocationList-ForDCIformat0_1. Since the set of temporary domain resources is specific to DCI information, all temporary domain resources for data scheduled in the first DCI format are specifically temporary domain resources from the first set of temporary domain resources.

In one embodiment, the terminal device may further receive first indication information from the network device, where the first indication information is used to indicate a time domain recurrence method with grant-free scheduling. The terminal device determines a third set of temporary domain resources for grant-free scheduling based on a time-domain iteration method with grant-free scheduling and at least one set of temporary domain resources.

Specifically, in one embodiment, in addition to transmitting first direction information to the terminal device, the network device may transmit second direction information to the terminal device. This second indication information is used to indicate a time domain repetition method for the first DCI format, and is used to indicate a time domain repetition method for the second DCI format. The terminal device then determines a third set of temporary domain resources for grant-free scheduling based on the time-domain iteration method with grant-free scheduling and the specified at least one set of temporary domain resources. Specifically, the third set of temporary domain resources for non-grant planning is determined in accordance with the following rules.

Rule 1: If the time domain retry method with non-grant scheduling is the same as both the time domain retry method for the first DCI format and the retry method for the second DCI format, but the second DCI format does not have a specific set time domain resources, the at least one set of time domain resources is determined to be a third set of time domain resources for non-grant scheduling.

The fact that the second DCI format does not have a specific time domain resource set means that for the second DCI format, the network device does not transmit Y indication information for indicating a time domain resource set (in other words, a second time domain resource set) specific for the second DCI format. The fact that the set of temporary domain resources is specific to the second DCI format means that all temporary domain resources for data scheduled in the second DCI format are definitely resources from the second set of temporary domain resources.

Rule 2: The time domain retry method with grant-free scheduling, the time domain retry method for the first DCI format, and the retry method for the second DCI format are all different, and there is no set of time domain resources specific to the second DCI format. format. In this case, the at least one set of temporary domain resources is determined to be a third set of temporary domain resources for scheduling without the use of grants.

For example, a network device configures a time domain resource table in normal DCI format for a terminal device using RRC control signaling, and the network device further indicates to the terminal device that a time domain recurrence method with scheduling without the use of grants is a time domain recurrence method. slot-based areas. Since the network device indicates, in the second indication information, that the normal DCI format corresponds to a slot-based time domain repetition method and that the compact DCI format corresponds to a slot-based time domain repetition method, the terminal device may determine that the time domain repetition method non-grant scheduling domains are the same as the time domain iteration methods for the normal DCI format and the compact DCI format. However, since the network device does not configure a compact DCI format temporary domain resource table for the terminal device, the terminal device determines that the normal DCI format temporary domain resource table is the temporary domain resource table to use.

According to the Case 1 method, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is the same as a time domain repetition method without grants (GF) can be defined as a set of time domain resources corresponding to the repetition method in the time domain without grants (GF). First, the network device and the end device define a set of temporary domain resources using the same rule, so that the sets of temporary domain resources found as a result of the definition by the network device and the end device can be assured that they will be consistent to ensure that that the same resource for data transfer is defined and normal communication is ensured. Secondly, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting the time domain resource sets with the same repetition method can ensure the time domain repetition method and ensure that all time domain resources in these sets of time domain resources can conform to the characteristics of the time domain repetition method, thereby ensuring normal communication.

It should be noted that the above description is made using an example in which the at least one set of temporary domain resources is exactly one set of temporary domain resources and is a first set of temporary domain resources corresponding to the first DCI format, and there is no set time domain resources specific to the second DCI format. When the at least one temporary domain resource set is exactly one temporary domain resource set and is a second temporary domain resource set corresponding to a second DCI format, and there is no temporary domain resource set specific to the second DCI format, the method is completely the same, so the details will not be described again here.

Case 2: When the at least one temporary domain resource set is a collection of two temporary domain resource sets, the collection of two temporary domain resource sets may comprise a first temporary domain resource set corresponding to the first DCI format and a second temporary domain resource set corresponding to the second DCI format.

The procedure in which a terminal device determines a first set of temporary domain resources corresponding to a first DCI format and a set of temporary domain resources corresponding to a second DCI format may be implemented using Method 1 of Case 1, or using either from the following methods.

Method 2: First, a set of time domain resources corresponding to a specific DCI format is determined in accordance with Method 1. If it is found that this DCI format does not have a specific set of time domain resources, the set of time domain resources corresponding to this DCI format is can be determined in the manner shown in Table. 3.

Method 3: The set of temporary domain resources corresponding to the DCI format in question can be determined in the manner shown in Table. 3, in other words, a set of time domain resources specific to the terminal device in Tab. 3 is changed to a set of time domain resources specific to the DCI format in question.

Case 2 further contains the following Case 2.1 – Case 2.3.

Case 2.1: The terminal device selects, from a specified plurality of at least one time domain resource set, a second time domain resource set corresponding to a second DCI format as a third time domain resource set.

For example, the network device configures a set of time domain resources corresponding to the normal DCI format and a set of time domain resources corresponding to the compact DCI format for the terminal device using RRC control signaling, or defines a set of time domain resources corresponding to the normal DCI format, and a temporary domain resource set corresponding to the compact DCI format according to Method 1, Method 2 or Method 3 above. In this case, the terminal device determines that the temporary domain resource set corresponding to the compact DCI format is a temporary domain resource set , which must be used.

In an alternative embodiment, the terminal device selects, from among the at least one set of time domain resources, a first set of time domain resources corresponding to the first DCI format as a third set of time domain resources.

For example, a network device configures a set of time domain resources corresponding to a normal DCI format and a set of time domain resources corresponding to a compact DCI format for a terminal device using RRC control signaling. In this case, the terminal device determines the set of temporary domain resources corresponding to the normal DCI format as the set of temporary domain resources to be used.

According to the method described in Case 2.1, the set of time domain resources for the grant-free (GF) mode is specified to be a set of time domain resources corresponding to a DCI format (a first DCI format or a second DCI format). The network device and the end device define a set of temporary domain resources using the same rule, so that you can be sure that the sets of temporary domain resources defined by the network device and the end device will be consistent to ensure that the same ones are defined time domain resources for data transmission, and ensure communication reliability.

Case 2.2: In one embodiment, the terminal device may further receive third indication information from the network device, where this third indication information is used to indicate which one of the two sets of time domain resources is the third set of time domain resources.

Specifically, in one case, the first indication information may indicate that the first set of temporary domain resources is used as a third set of temporary domain resources. After receiving the third indication information, the terminal device may use the first set of temporary domain resources as a third set of temporary domain resources based on the third indication information. In another case, the first indication information may indicate that the second set of temporary domain resources is used as the third set of temporary domain resources. After receiving the third indication information, the terminal device may use the second set of time domain resources as the third set of time domain resources based on the third indication information.

For example, the network device configures a set of time domain resources corresponding to the normal DCI format and a set of time domain resources corresponding to the compact DCI format for the terminal device using RRC control signaling, or defines a set of time domain resources corresponding to the normal DCI format, and a temporary domain resource set corresponding to the compact DCI format according to Method 1, Method 2 or Method 3 above. The network device further indicates to the terminal device that the temporary domain resource set corresponding to the compact DCI format is a temporary domain resource set , which the end device needs to use. In this case, the terminal device determines that the set of temporary domain resources corresponding to the compact DCI format is the set of temporary domain resources to be used.

According to the method discussed in Case 2.2, higher layer signaling is used to indicate a set of time domain resources corresponding to a DCI format (first DCI format or second DCI format) for grant-free (GF) mode, both the network device and the terminal device define a set of temporary domain resources using the same rule, so that you can be sure that the sets of temporary domain resources found by the network device and the end device will be consistent, so that you can ensure that the same temporary domain resource is defined for data transmission, and ensure reliable communication. In addition, since a set of temporary domain resources corresponding to the Grant-Free (GF) mode is configured by the network device, it can be ensured that the configured set of temporary domain resources satisfies the Grant-Free (GF) mode's service requirements as much as possible, and scheduling flexibility is provided. resources and reliability.

As an option, in Case 2.2, if the terminal device has not received the first indication information, in other words, the network device has not transmitted this first indication information, the third set of temporary domain resources can be determined in the manner shown in Table. 3, either a set of temporary domain resources corresponding to a first DCI format may be used, or a set of temporary domain resources corresponding to a second DCI format may be used. According to this method, when the network device has not specified the third temporary domain resource set, the network device and the terminal device determine the temporary domain resource set using the same rule, so that it can be assured that the temporary domain resource sets specified by the network device and terminal device will be consistent to ensure that the same time domain resource for data transmission is identified and to ensure communication reliability.

Case 2.3: In addition to transmitting the first indication information to the terminal device, the network device may further transmit the second indication information to this terminal device. This second indication information is used to indicate a time domain repetition method for the first DCI format, and is also used to indicate a time domain repetition method for a second DCI format. The terminal device determines a third set of time domain resources based on a time domain repetition method with grant-free scheduling, a time domain repetition method for a first DCI format, and/or a time domain repetition method for a second DCI format.

Method 3: The terminal device determines, as the third time domain resource set from the first time domain resource set and from the second time domain resource set, a time domain resource set corresponding to the DCI format for which the time domain repetition method is the same as a way to replicate in the time domain with planning without the use of grants. In other words, when it is determined that the time domain repetition method for the first DCI format is the same as the time domain repetition method with grant-free scheduling, the terminal device uses the first set of time domain resources as the third set of time domain resources; or when it is determined that the time domain repetition method for the second DCI format is the same as the time domain repetition method with grant-free scheduling, the terminal device uses the second set of time domain resources as the third set of time domain resources.

For example, a network device configures a time domain retry method with grant-free scheduling as a slot-based time domain retry method for a terminal device using RRC control signaling. The network device configures, for a terminal device using RRC control signaling, a set of time domain resources corresponding to the normal DCI format and a set of time domain resources corresponding to the compact DCI format, or defines a set of time domain resources corresponding to the normal DCI format, and a set of time domain resources corresponding to a compact DCI format, according to Method 1, Method 2, or Method 3. The network device further indicates to the terminal device that the normal DCI format corresponds to a slot-based time domain repetition method, and that the compact DCI format corresponds to the mini-slot based time domain repetition method. Therefore, the terminal device may determine that the time domain repetition method with grant-free scheduling is the same as the time domain repetition method for the normal DCI format, and the terminal device determines that the time domain resource table corresponding to the normal DCI format , represents the temporary domain resource table to be used.

According to Method 3, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is the same as the time domain repetition method for a grant-free (GF) mode can be defined as a set of time domain resources corresponding to the mode without grants (GF), based on the time domain repetition method for the non-grants (GF) mode. First, the network device and the end device define a set of time-domain resources using the same rule, so that the sets of time-domain resources defined by the network device and the end device can be assured to be consistent, thereby ensuring communication reliability. Secondly, since the time domain resources in time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting time domain resource sets with the same repetition method can ensure that all time domain resources in the considered resource sets time domain can correspond to this time domain repetition method, thereby ensuring normal communication.

Method 4: The terminal device determines, as the third time domain resource set from the first time domain resource set and the second time domain resource set, a time domain resource set corresponding to the DCI format for which the time domain repetition method is the same as the repetition method in the time domain with planning without the use of grants. When both the time domain repetition method for the first DCI format and the time domain repetition method for the second DCI format are the same as the time domain repetition method with grant-free scheduling, the terminal device determines the specified second set of time resources. domain as a third set of temporary domain resources, or the terminal device defines said first set of temporary domain resources as a third set of temporary domain resources. In other words, the terminal device defines a set of time domain resources corresponding to the second DCI format as a third set of time domain resources, or the terminal device defines a set of time domain resources corresponding to the first DCI format as a third set of time domain resources, or the device defines a third set of temporary domain resources in the manner shown in Table. 3.

For example, a network device configures a time domain retry method with grant-free scheduling as a slot-based time domain retry method for a terminal device using RRC control signaling. This network device configures, for a terminal device using RRC control signaling, a set of time domain resources corresponding to the normal DCI format and a set of time domain resources corresponding to the compact DCI format, or defines a set of time domain resources corresponding to the normal DCI format, and a set of time domain resources corresponding to a compact DCI format according to Method 1, Method 2, or Method 3. The network device further indicates to the terminal device that the normal DCI format corresponds to a slot-based time domain repetition method, and that the compact DCI -format corresponds to the slot-based time domain repetition method. Therefore, the terminal device may determine that the time domain repetition method with grant-free scheduling is the same as both the time domain repetition method for the normal DCI format and the method for the time domain resource set corresponding to the compact DCI format, and the terminal device determines that the set of time domain resources corresponding to the normal DCI format is a set of time domain resources to be used, or the terminal device determines that the set of time domain resources corresponding to the compact DCI format is a set of time domain resources , which must be used.

According to Method 4, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is the same as the time domain repetition method in the grant-free (GF) mode can be defined as a set of time domain resources corresponding to the non-grant (GF) mode, based on the time domain repetition method for the non-grant (GF) mode. First, the network device and the end device define a set of temporary domain resources using the same rule, so that it can be ensured that the sets of temporary domain resources defined by the network device and the end device will be consistent, so that it can be ensured that the same resource for data transmission will be determined, and communication reliability will be ensured. Secondly, since the time domain resources in time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting time domain resource sets with the same repetition method can ensure that all time domain resources in the considered resource sets time domain can correspond to a specified time domain repetition method, thereby ensuring normal communication. In addition, when multiple time domain resource sets may correspond to any one time domain repetition method characteristic, it is specified that one of the DCI formats or one of the time domain resource sets is the final used time domain resource set, so that it is ensured that the network device and the terminal device define the same set of time-domain resources, thereby ensuring communication reliability.

Method 5: The terminal device determines, as the third time domain resource set from the first time domain resource set and the second time domain resource set, a time domain resource set corresponding to the DCI format for which the time domain repetition method is the same as the repetition method in the time domain with planning without the use of grants. When both the time domain repetition method for the first DCI format and the time domain repetition method for the second DCI format are different from the time domain repetition method with grant-free scheduling, the terminal device designates the second set of time domain resources as the third the temporary domain resource set, or the terminal device designates the first temporary domain resource set as the third temporary domain resource set. Alternatively, the third set of temporary domain resources may be defined in the manner shown in Table 1. 3.

For example, a network device configures a time domain retry method with grant-free scheduling as a slot-based time domain retry method for a terminal device using RRC control signaling. This network device configures, for a terminal device using RRC control signaling, a time domain resource table for the normal DCI format and a time domain resource table for the compact DCI format. The network device further indicates to the terminal device that the normal DCI format corresponds to the mini-slot-based time domain repetition method, and that the compact DCI format corresponds to the mini-slot-based time domain repetition method. Therefore, the terminal device may determine that the time domain repetition method with grant-free scheduling is different from both the time domain repetition method for the normal DCI format and the time domain resource set method corresponding to the compact DCI format, and the terminal device determines that the set of time domain resources corresponding to the normal DCI format is a set of time domain resources to be used, or the terminal device determines that the set of time domain resources corresponding to the compact DCI format is a set of time domain resources , which must be used.

According to Method 5, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is the same as the time domain repetition method for a grant-free (GF) mode can be defined as a set of time domain resources corresponding grant-free (GF) mode, based on the time-domain repetition method of grant-free (GF) mode. First, the network device and the end device define a set of temporary domain resources using the same rule, so that it can be assured that the sets of temporary domain resources defined by the network device and the end device will be consistent to ensure that the the same resource for data transmission, and ensure reliable communication. Secondly, since the time domain resources in time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting time domain resource sets with the same repetition method can ensure that all time domain resources in these resource sets time domain can correspond to one characteristic of the time domain repetition method, thereby ensuring normal communication. In addition, when multiple time domain resource sets may correspond to a specified time domain repetition method characteristic, it is specified that one of the DCI formats or one of the time domain resource sets is the finally used time domain resource set, so that it is ensured that the network the device and the terminal define the same set of time-domain resources, thereby ensuring reliable communication.

Method 6: The terminal device determines, as the third time domain resource set from the first time domain resource set and the second time domain resource set, a time domain resource set corresponding to the DCI format for which the time domain repetition method is the same as the repetition method in the time domain with planning without the use of grants. When both the time domain repetition method for the first DCI format and the time domain repetition method for the second DCI format are different from the time domain repetition method with grant-free scheduling, the terminal device determines the third set of time domain resources in the manner shown in Table. 3. The default set of time domain resources in the protocol, namely the fourth set of time domain resources, is defined as the third set of time domain resources. In an alternative embodiment, a terminal device-specific set of temporary domain resources, namely a fourth set of temporary domain resources, is used as a third set of temporary domain resources. In an alternative embodiment, a set of temporary domain resources designated by the system information, namely a fourth set of temporary domain resources, is used as a third set of temporary domain resources.

For example, a network device configures a time domain repetition method with grant-free scheduling as a slot-based time domain repetition method for a terminal device using RRC control signaling, and the network device configures a time domain resource table for normal DCI format and a table time domain resources for a compact DCI format for a terminal device using RRC control signaling. This network device further indicates to the terminal device that the normal DCI format corresponds to the mini-slot-based time domain repetition method, and the compact DCI format corresponds to the mini-slot-based time domain repetition method. Therefore, the terminal device may determine that the time domain repetition method with non-grant scheduling is different from both the time domain repetition method for the normal DCI format and the time domain repetition method for the compact DCI format. Therefore, the terminal device defines a default time domain resource table in the protocol, namely the fourth set of time domain resources, as the third set of time domain resources. In an alternative embodiment, a terminal device-specific set of temporary domain resources, namely a fourth set of temporary domain resources, is used as a third set of temporary domain resources. In an alternative embodiment, a set of temporary domain resources designated by the system information, namely a fourth set of temporary domain resources, is used as a third set of temporary domain resources.

According to Method 6, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is the same as the time domain repetition method for a grant-free (GF) mode can be defined as a set of time domain resources corresponding to the non-grant (GF) mode, based on the time domain repetition method for the non-grant (GF) mode. First, the network device and the end device define a set of temporary domain resources using the same rule, so that it can be assured that the sets of temporary domain resources defined by the network device and the end device will be consistent to ensure that the the same resource for data transmission, and ensure reliable communication. Secondly, since the time domain resources in time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting time domain resource sets with the same repetition method can ensure the time domain repetition method in question and ensure that all time domain resources in the time domain resource sets can correspond to one characteristic of the time domain repetition method, thereby ensuring normal communication. In addition, when multiple time domain resource sets cannot meet the specified characteristic of the time domain repetition method, defining the time domain resource set as the finally used time domain resource set in a manner known in the art so that the implementation complexity is reduced, this allows it to be confident that the network device and the end device will identify the same set of time-domain resources, and communication reliability will be ensured.

In one embodiment, step 302 and step 303 shown in FIG. 3 may be replaced by the following: The terminal device receives the indication information, and this indication information directly specifies the start symbol and the length of the third temporary domain resource for scheduling without using grants, in other words, the third temporary domain resource is directly determined.

As shown in FIG. 4, one embodiment of the present application proposes a simplified logic diagram of the second communication method. This method is applicable to the non-grant (GF) scheduling scenario and can be implemented by the network device. As shown in FIG. 4, this method contains the following steps.

Step 401: The network device determines at least one set of temporary domain resources, where each of the plurality of the at least one set of temporary domain resources corresponds to one DCI format.

The at least one set of time domain resources may be configured using higher layer signaling, or may be predefined in a protocol. The set of temporary domain resources may be, for example, a temporary domain resource table shown in Table. 1, Table. 2 and Table. 4, or may have another shape. This is not limited in this application.

In one embodiment, the at least one set of temporary domain resources may be one set of temporary domain resources, or may be two sets of temporary domain resources, or the at least one set of temporary domain resources may be a combination of three or more sets of temporary domain resources. When the at least one temporary domain resource set is two temporary domain resource sets, the two temporary domain resource sets may include a first temporary domain resource set corresponding to a first DCI format and a second temporary domain resource set corresponding to a second DCI format . It should be noted that the first DCI format in the following can be understood as a normal DCI format (or understood as DCI format 0_1 or DCI format 1_1), and the second DCI format can be understood as a compact DCI format (or understood as DCI format 0_2 or DCI format 1_2). The third DCI format can be understood as a recovery DCI format (or understood as DCI format 0_0 or DCI format 1_0).

Step 402: The network device determines a third set of temporary domain resources for grant-free scheduling based on the at least one set of temporary domain resources.

In particular, the network device may determine a third set of time domain resources for grant-free scheduling based on information such as a time domain repetition method and a DCI format corresponding to the at least one set of time domain resources in accordance with a pre-negotiated rule. For information about a specific rule, see the following.

Step 403: The network device determines a third temporary domain resource from a third set of temporary domain resources.

Step 404: The network device transmits downlink data to the terminal device using the found third time domain resource, or receives uplink data using the third time domain resource.

For information about various instances of determining a third set of temporary domain resources at step 402 in the embodiment shown in FIG. 4, refer to the description of various cases of determining the third set of temporary domain resources in the embodiment corresponding to FIG. 3. The details will not be described again here.

In this embodiment of the present application, the network device and the terminal device define a set of temporary domain resources using the same rule, so that the sets of temporary domain resources determined by the network device and the terminal device can be assured to be consistent, thereby ensuring that that the same resource will be identified for data transfer and ensuring normal communication. In addition, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, by selecting the time domain resource sets corresponding to the same repetition method, one can be confident in the time domain repetition method and ensure that all time domain resources in the found time domain resource sets can match the characteristic of the selected time domain repetition method, thereby ensuring normal communication.

As shown in FIG. 5, one of the variants of this application offers a simplified diagram of the third communication method. This communication method is applicable to the grant-based (GB) scheduling scenario and can be implemented by the endpoint. As shown in FIG. 5, the method contains the following steps.

Step 501: The network device configures two sets of time domain resources for the terminal device using RRC control signaling.

Step 502: The terminal device receives two sets of temporary domain resources from the network device.

For example, a network device configures two sets of time domain resources for an end device using RRC control signaling. These two sets of temporary domain resources are respectively a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format. Alternatively, the first set of temporary domain resources corresponding to the normal DCI format and the second set of temporary domain resources corresponding to the compact DCI format may be determined in accordance with Method 1, Method 2, or Method 3 discussed above.

Step 503: The network device transmits DCI information in a third DCI format to the terminal device.

In particular, the network device schedules uplink data and/or downlink data transmissions using DCI information transmitted on a physical downlink control channel (PDCCH). In this case, the time domain position of the transmission resource used to transmit uplink data and/or downlink data is determined based on the time domain position of the PDCCH and the time domain information specified in the DCI information.

Step 504: The terminal device receives DCI information in a third DCI format from the network device.

For example, a network device transmits DCI information in a recovery DCI format to the end device.

Step 505: The terminal device determines a third set of time domain resources corresponding to DCI information in a third DCI format, where the third set of time domain resources is one of the two sets of time domain resources.

In particular, the terminal device may determine the third set of time domain resources based on information such as indications of time domain repetition methods and DCI formats for the two sets of time domain resources in question in accordance with a pre-agreed rule. The specific rule is given below.

Step 506: The terminal device determines a third temporary domain resource from a third set of temporary domain resources.

Step 507: The terminal device transmits uplink data using the found third time domain resource, or receives downlink data using this third time domain resource.

The following describes various cases of determining a third set of temporary domain resources at step 505 in the embodiment shown in FIG. 5.

Case 3: In addition to receiving DCI information, the terminal device receives sixth indication information, where the sixth indication information is used to indicate a time domain repetition method for the first DCI format and a time domain repetition method for the second DCI format. The terminal device may determine the third set of time domain resources in one or more of the following ways based on the time domain repetition methods for the specified DCI formats.

Method 7: The terminal device determines, as the third set of temporary domain resources, a set of temporary domain resources corresponding to the mini-slot level repetition method. Further, the terminal device may determine a temporary domain resource from a set of temporary domain resources corresponding to the mini-slot level repetition method.

Optionally, if the set of temporary domain resources corresponding to the mini-slot level repetition method contains a slot-boundary-crossing temporary-domain resource, a non-slot-boundary-crossing resource is selected from the set of temporary domain resources.

For example, a network device configures two sets of time domain resources for an end device using RRC control signaling. These two sets of temporary domain resources are, respectively, a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format. Alternatively, the terminal device may determine a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format according to Method 1, Method 2 or Method 3 above. The network device indicates whether the terminal device device that the normal DCI format corresponds to a slot-based time domain repetition method, and the compact DCI format corresponds to a mini-slot-based time domain repetition method. The terminal device may determine that the second set of time domain resources corresponding to the mini-slot-based time domain repetition method is a set of time domain resources (namely, a third set of time domain resources) to be used.

According to Method 7, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is a mini-slot level repetition method is determined as a set of time domain resources corresponding to DCI recovery information, and from this set of time domain resources is selected only a set that does not cross a slot boundary. The network device and the end device define a set of temporary domain resources using the same rule, so that you can be sure that the sets of temporary domain resources defined by the network device and the end device will be consistent to ensure that the same resource for data transmission and ensure normal communication and reliable communication. In addition, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, the time domain resource set corresponding to, rows that do not cross the slot boundary is selected as the time domain resource set corresponding DCI recovery information. Therefore, it can be ensured that all the time domain resources in the time domain resource sets corresponding to the time domain repetition method under consideration can meet the boundary "non-crossing" characteristic, so that normal communication is ensured.

Method 8: The terminal device determines, as the third set of temporary domain resources, a set of temporary domain resources corresponding to the slot-level repetition method.

For example, a network device configures two sets of time domain resources for an end device using RRC control signaling. These two sets of temporary domain resources are, respectively, a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format. Alternatively, the terminal device may determine a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format in accordance with Method 1, Method 2, or Method 3 above. The network device indicates , to the terminal device that the normal DCI format corresponds to a slot-based time domain repetition method, and the compact DCI format corresponds to a mini-slot-based time domain repetition method. In this case, the terminal device may determine that the first time domain resource table corresponding to the slot-based time domain repetition method is a time domain resource table (namely, a third set of time domain resources) to be used.

According to Method 8, a set of time domain resources corresponding to a DCI format for which the time domain repetition method is a slot-level repetition method is determined as a set of time domain resources corresponding to DCI recovery information. The network device and the end device define a set of temporary domain resources using the same rule, so that you can be sure that the sets of temporary domain resources defined by the network device and the end device will be consistent to ensure that the same resource is determined for transmission data and ensure normal communication and reliable communication. In addition, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting a time domain resource set corresponding to the DCI format for which the time domain repetition method is a slot level, as a set of time domain resources corresponding to the recovery information, the DCI can ensure that all the time domain resources in the sets of time domain resources corresponding to the time domain repetition method in question can meet the boundary non-crossing characteristic, so that normal communication is ensured .

Method 9: The terminal device determines that the set of temporary domain resources corresponding to the mini-slot level repetition method is the third set of temporary domain resources. If there is no time domain resource set corresponding to the mini-slot level repetition method, the terminal device determines that the time domain resource set predefined in the protocol is the third time domain resource set. For example, if there is no DCI format corresponding to slot-level repetition, in other words, none of the DCI formats is configured as a format corresponding to mini-slot repetition, a set of temporary domain resources can be determined in accordance with the method described in Table 3.

Method 10: The terminal device determines that the set of temporary domain resources corresponding to the slot-level repetition method is the third set of temporary domain resources. If there is no time domain resource set corresponding to the slot-level repetition method, the terminal device determines that the time domain resource set predefined in the protocol is the third time domain resource set. For example, if there is no DCI format corresponding to slot-level repetition, in other words, none of the DCI formats is configured as a format corresponding to mini-slot repetition, a set of temporary domain resources can be determined in accordance with the method described in Table 3.

It should be noted that the terminal device may determine the third set of temporary domain resources in the above several ways. For example, a terminal device first determines a set of temporary domain resources according to Method 7, and if the terminal device fails to determine a set of temporary domain resources according to Method 7, the terminal device determines a set of temporary domain resources according to Method 8.

Case 4: In one embodiment, the terminal device receives seventh indication information, where the seventh indication information may indicate a set of time domain resources corresponding to a third DCI format. For example, the seventh indication information may indicate a specific set of temporary domain resources, or may indicate a specific set of temporary domain resources from two sets of temporary domain resources. The terminal device determines a third set of temporary domain resources based on the seventh indication information.

For example, a network device configures two sets of time domain resources for an end device using RRC control signaling. These two sets of temporary domain resources are, respectively, a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format. Alternatively, the terminal device may determine a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format according to Method 1, Method 2 or Method 3 above. The network device transmits the seventh information instructing the terminal device using RRC control signaling, where this seventh indication information is used to indicate that the first set of time domain resources corresponding to the normal DCI format is a set of time domain resources that the terminal device needs to use. Therefore, after receiving the seventh indication information, the terminal device determines the first set of time domain resources corresponding to the normal DCI format as the set of time domain resources to be used by the terminal device, and then receives and transmits data using one of the time domain resources from the specified set of temporary domain resources.

According to the method described in Case 4, higher layer signaling is used to indicate a set of temporary domain resources corresponding to a DCI format (first DCI format or second DCI format) for DCI recovery information, and the network device and the terminal device determine the set of temporary domain resources area using the same rule, so that you can be sure that the sets of time domain resources defined by the network device and the end device will be consistent, to ensure that the same time domain resource is defined for data transmission, and to ensure reliability communications. In addition, since the set of temporary domain resources corresponding to the DCI recovery information is configured by the network device, it is possible to ensure that the configured set of temporary domain resources satisfies the requirements of the DCI recovery information as far as possible, and ensure flexibility and reliability in resource scheduling.

Case 5: The end device does not select a time-domain resource set from two time-domain resource sets configured by the network device, but uses the time-domain resource set predefined in the protocol as the third time-domain resource set, or determines the third time-domain resource set according to the method described in Table. 3.

In one embodiment, step 503 and step 504 shown in FIG. 5 can be replaced as follows: The terminal device determines the start symbol and the length of the resource in the third set of time domain resources corresponding to the DCI information in the third DCI format, in other words, directly determines the third time domain resource.

As shown in FIG. 6, one embodiment of the present application proposes a simplified logic diagram of the fourth communication method. This method is applicable to the non-grant (GF) scheduling scenario and can be implemented by the network device. As shown in FIG. 6, the method contains the following steps.

Step 601: The network device determines two sets of temporary domain resources.

The two sets of temporary domain resources are a first set of temporary domain resources corresponding to a first DCI format and a second set of temporary domain resources corresponding to a second DCI format.

For example, the network device configures these two sets of time domain resources for the terminal device using RRC control signaling. These two sets of temporary domain resources are, respectively, a first set of temporary domain resources corresponding to the normal DCI format and a second set of temporary domain resources corresponding to the compact DCI format. Alternatively, the first set of temporary domain resources corresponding to the normal DCI format and the second set of temporary domain resources corresponding to the compact DCI format may be determined according to Method 1, Method 2 or Method 3 above.

Step 602: The network device transmits DCI information in a third DCI format to the terminal device.

For example, a network device transmits a temporary domain resource table in a recovery DCI format to the end device.

Step 603: The terminal device determines a third set of time domain resources corresponding to DCI information in a third DCI format, where the third set of time domain resources is one of the two sets of time domain.

In particular, the network device may determine a third set of time domain resources based on information such as time domain repetition methods and DCI formats for the two sets of time domain resources, in accordance with a pre-agreed rule. Information about the specific rule is provided below.

Step 604: The network device determines a third temporary domain resource from a third set of temporary domain resources.

Step 605: The network device transmits downlink data using the found third time domain resource, or receives uplink data using the third time domain resource.

For various cases of determining the third set of temporary domain resources at step 603 in the embodiment shown in FIG. 6, it is necessary to refer to the description of various cases of determining the third set of time domain resources in the embodiment corresponding to FIG. 5. The details will not be described again here.

In this embodiment of the present application, the network device and the terminal device define a set of temporary domain resources using the same rule, so that the sets of temporary domain resources determined by the network device and the terminal device can be assured to be consistent, thereby ensuring that that the same data transmission resource will be determined and normal communication will be ensured. In addition, since the time domain resources in the time domain resource sets corresponding to different time domain repetition methods have different characteristics, selecting the time domain resource sets corresponding to the same repetition method can provide the specified time domain repetition method and ensure that all time domain resources in the time domain resource sets can comply with the characteristic of the time domain repetition method, thereby ensuring normal communication.

From examination of the related state-of-the-art technology set forth in the R16 standard, it can be seen that the normal DCI format or the compact DCI format may be configured by a slot-level time domain repetition method, or may be configured by a time domain repetition method at the mini slot level. Different time domain repetition mechanisms have different characteristics. For example, (1) for repetition at the mini-slot level, the time domain resource indicated by the indication information can cross the slot boundary, and for repetition at the slot level, the time domain resource indicated by the indication information cannot cross the slot boundary; (2) for mini-slot level repetition, only type B mapping is supported, and for slot level repetition, both type A and type B are supported; (3) for mini-slot level repetition, the number of repetitions can only be added to an existing column in the temporary domain resource table, and for slot level repetition, a column can be added to the temporary domain resource table, or the number of repetitions is directly supported by configuration on higher level without adding a column.

Assume that higher layer signaling is used to configure only one time domain resource table for uplink transmissions from a terminal device. In this case, regardless of whether the terminal device receives normal DCI information or compact DCI information, the terminal device can arbitrarily determine the time domain resource from the time domain resource table. However, the temporary domain resources corresponding to some rows in the temporary domain resource table are not applicable to some DCI formats. For example, if normal DCI information transmitted by a network device to an end device is configured in slot-level repeat mode, the time domain resources corresponding to the boundary crossing rows in the time domain resource table cannot be used. As another example, if the DCI compact information is configured in repeat mode at the mini-slot level, a row having mapping type A in the time domain resource table cannot be used. Therefore, a mechanism is needed to ensure that a time domain resource table corresponding to a DCI format of DCI information coming from a network device can match the time domain repetition method configured for that DCI format. In view of this, one embodiment of the present application proposes a simplified logic diagram of the fifth communication method, as shown in FIG. 7. This method is applicable to the grant-based (GB) scheduling scenario and can be implemented by the endpoint. As shown in FIG. 7, the method contains the following steps.

Step 701: The network device transmits DCI information in a first DCI format to the terminal device.

For example, a network device transmits DCI information in normal DCI format or DCI information in compact DCI format to the terminal device.

Step 702: The terminal device receives DCI information from the network device.

Step 703: The terminal device determines a second set of time domain resources from the first set of time domain resources based on the first DCI format of the DCI information.

Specifically, the terminal device may determine the second set of time domain resources based on information such as an indication of a time domain repetition method corresponding to the first set of time domain resources and DCI information for the first DCI format in accordance with a pre-negotiated rule. Information about the specific rule is provided below.

Step 704: The terminal device determines a second temporary domain resource from a second set of temporary domain resources.

Step 705: The terminal device receives downlink data using the found second time domain resource, or transmits uplink data using this second time domain resource.

The following describes various instances of determining a second set of temporary domain resources at step 704 in the embodiment shown in FIG. 7.

Example 1: In one embodiment, the terminal device may further receive fourth indication information from the network device, where the fourth indication information is used to indicate a time domain repetition method for the DCI information. The terminal device may determine a second set of time domain resources from the first set of time domain resources based on the first DCI format of the DCI information and the time domain repetition method for that DCI information. In other words, the terminal device can determine in any one or more of the following ways based on whether the DCI format is a normal DCI format or a compact DCI format, and whether a time domain repetition method is used at the mini-slot level or a slot-level time domain repetition method, a second set of time domain resources that satisfies a condition from the first set of time domain resources.

Method 11: When the first DCI format of DCI information coming from a network device is a normal DCI format or a compact DCI format (in other words, DCI format 0_1, DCI format 0_2, DCI format 1_1, or DCI format 1_2 ), and the fourth indication information indicates that the time domain repetition method for this DCI information is a slot-level repetition method, the terminal device determines, from the first set of time domain resources, that the time domain resource that does not cross a slot boundary is the second time domain resource.

For example, as shown in FIG. 2C, if the starting character in a line in the first set of time domain resources is character 12, the length is four characters, and the number of repetitions is 2, it can be determined that the corresponding time domain resource crosses the boundary, and the terminal device will not select this time domain resource. In contrast, if the time-domain resource in question does not cross the boundary, the terminal device will select that time-domain resource as the second time-domain resource.

Method 12: When the first DCI format of DCI information coming from a network device is a normal DCI format or a compact DCI format (in other words, DCI format 0_1, DCI format 0_2, DCI format 1_1, or DCI format 1_2 ), and the fourth indication information indicates that the time domain repetition method for the DCI information is a slot-level repetition method, the terminal device determines, from the first set of time domain resources, that the time domain resource that does not contain repetition number information is the second time domain resource.

For example, the first set of temporary domain resources is the temporary domain resource table shown in Table. 5. The terminal device determines that the time domain resource for which the number of repetitions R is not equal to 0 in Table. 5 is the second temporary domain resource. In other words, the end device will not select the time domain resource corresponding to row number 1 in Table. 1, and will select the temporary domain resource corresponding to line number 2, line number 3, or line number 16 as the second temporary domain resource.

Table 5

Row index (line number) Channel display type PUSCH/PDSCH K2/K1 SLIV
or S/L Number of R repetitions 1 Type A x x 0 2 Type B x x 2 2 Type B x x 2 ... ... ... ... ... 16 Type B x x 3

Method 13: When the first DCI format of DCI information coming from a network device is any one of DCI Format 0_1, DCI Format 0_2, DCI Format 1_1 or DCI Format 1_2, and the time repeat method domain for this DCI information is a mini-slot level repetition method, the terminal device determines, from the first set of time domain resources, a time domain resource for which the mapping type is type B as the second time domain resource, or the terminal device determines, from of the first set of temporary domain resources, a temporary domain resource containing information about the number of repetitions, as a second temporary domain resource.

For example, the first set of temporary domain resources is the temporary domain resource table shown in Table. 5. The terminal device determines that the temporary domain resource for which the mapping type is type B in Table. 5 represents a second temporary domain resource. In other words, the end device does not select the time domain resource corresponding to row number 1 in Table. 1, a selects the temporary domain resource corresponding to line number 2, line number 3, or line number 16 as the second temporary domain resource.

As another example, the terminal device determines that a temporary domain resource for which the number of repetitions R is not equal to 0 in Tab. 5 is the second temporary domain resource, or the terminal device determines that the temporary domain resource for which in Tab. 5, the number of repetitions R is present, represents the second time domain resource. In other words, the end device does not select the time domain resource corresponding to row number 1 in Table. 1, a selects the temporary domain resource corresponding to line number 2, line number 3, or line number 16 as the second temporary domain resource.

Method 14: When the first DCI format DCI information coming from the network device matches the DCI recovery information (in other words, it is DCI format 0_0 or DCI format 1_0), the terminal device determines, from the first set of time domain resources, the time domain resource , which does not cross a slot boundary, as a second temporary domain resource.

For example, a network device transmits DCI information in a recovery DCI format to the end device. This terminal does not select the boundary-crossing time domain resource shown in FIG. 2C. In contrast, the terminal device selects another, non-boundary-crossing time domain resource as the second time domain resource.

Method 15: When the first DCI format of the DCI information received from the network device matches the DCI recovery information (in other words, it is DCI format 0_0 or DCI format 1_0), the terminal device determines, from the first set of time domain resources, the time domain resource , which does not contain information about the number of repetitions, as a second temporary domain resource.

For example, a network device transmits DCI information in a recovery DCI format to the end device. This terminal determines that a time domain resource for which the number of repetitions R is not equal to 0 in Tab. 5 represents a second temporary domain resource. In other words, the end device does not select the time domain resource corresponding to row number 1 in Table. 1, a selects the temporary domain resource corresponding to line number 2, line number 3, or line number 16 as the second temporary domain resource.

Method 16: When the first DCI format of the DCI information coming from the network device matches the DCI recovery information (in other words, it is DCI format 0_0 or DCI format 1_0), the terminal device determines the second temporary domain resource in the manner shown in Table. 3, where this second temporary domain resource represents all temporary domain resources included in the set of temporary domain resources defined in accordance with Table. 3.

It should be noted that for Method 13 to Method 16, in one embodiment, when it is determined that the first DCI format of the DCI information matches the DCI information in the recovery DCI format, the terminal device further needs to determine whether the DCI information satisfies the first condition. If the DCI information satisfies the first condition, the second temporary domain resource is determined according to the appropriate Method 13 - Method 16.

This first condition is as follows: The DCI information scrambling method uses any one of C-RNTI, MCS-C-RNTI, TC-RNTI or CS-RNTI, and a PDCCH corresponding to this DCI information is received in the first search space where this first search space is a common search space (CSS) and the control resource CORESET associated with this CSS space is not CORESET 0; or the first search space is a terminal-specific search space (USS).

As shown in FIG. 8, one embodiment of the present application proposes a simplified logic diagram for a sixth communication method. This method is applicable to the non-grant (GF) scheduling scenario and can be implemented by the network device. As shown in FIG. 8, the method contains the following steps.

Step 801: The network device transmits DCI information to the terminal device, where the DCI information is in a first DCI format.

For example, the network device transmits DCI information in normal DCI format or DCI information in compact DCI format to the terminal device.

Step 802: The network device determines a second set of temporary domain resources from the first set of temporary domain resources based on the first DCI format of the DCI information.

Specifically, the network device may determine a second set of time domain resources based on information such as a time domain repetition method corresponding to the first set of time domain resources and DCI information in a first DCI format using a pre-negotiated rule. Information about the specific rule is provided below.

Step 803: The network device determines a second temporary domain resource from a second set of temporary domain resources.

Step 804: The network device receives uplink data using the found second time domain resource, or transmits uplink data using this second time domain resource.

Information about various instances of determining a third set of temporary domain resources at step 803 in the embodiment shown in FIG. 8 can be found in the above description of FIG. 7. The details will not be described again here.

In this embodiment of the present application, when the time domain resource table is configured at a higher level, for each format - normal DCI format and compact DCI format, a row that corresponds to the time domain repetition method corresponding to the DCI format is selected for indication from time domain resource table so that the number of bits in this DCI format can be reduced, and reducing the number of bits of DCI information ensures the reliability of this DCI information. For example, a temporary domain resource table has 64 rows, including 32 rows that cross a boundary and 32 rows that do not cross a boundary. If the DCI format only supports slot repetition, out of the specified 64 lines, 32 lines that do not cross the boundary can be selected for the DCI format. In other words, the number of bits in the DCI information is 5, and there is no need to occupy 6 bits to represent 64 values. There is only one table for DCI recovery information. In this case, the specified table can be used directly to avoid distortions. DCI recovery information does not support mini-slot repetition. Therefore, from the table in question, it is necessary to select SLIV parameters that satisfy the slot repetition requirement. Alternatively, the temporary domain resource table is configured at the time. For DCI recovery information, a temporary domain resource table predefined in the protocol is directly selected to reduce complexity. Therefore, you can be sure that the base station and the end device have the same understanding, thereby ensuring reliable communication.

A communication method comprising the steps of: defining two sets of time domain resources, the two sets of time domain resources being a first set of time domain resources corresponding to a first downlink control information (DCI) format and a second set of time domain resources corresponding to a second DCI format; transmitting DCI information in a third DCI format; determining a third set of time domain resources corresponding to DCI information in a third DCI format, wherein said third set of time domain resources is one of said two sets of time domain; determining a third temporary domain resource and a third set of temporary domain resources; And transmitting downlink data using the specified third time domain resource, or receiving uplink data using the specified third time domain resource. 49. The method according to claim 48, further comprising the step of: transmitting sixth indication information, wherein said sixth indication information is used to indicate a time domain repetition method for DCI information in a first DCI format and a time domain repetition method for DCI information in a second DCI format; wherein the step of determining a third set of temporary domain resources corresponding to the DCI information in the third DCI format comprises a substep of: determining, as the third set of temporary domain resources, a set of temporary domain resources corresponding to the mini-slot level repetition method or the slot level repetition method. 50. The method according to claim 48 or 49, further comprising the step of: transmitting seventh indication information, wherein said seventh indication information is used to indicate that one of said two sets of time domain resources is a third set of time domain resources. 51. A communication device comprising at least one processor coupled to a storage device, wherein said at least one processor is configured to read and execute a program stored in the storage device, causing the device to perform the method of any one of claims. 1–50. 52. A machine-readable storage medium storing computer instructions that cause, when executed by a computer, the computer to execute the method according to any one of claims. 1–50. 53. A communication device containing a communication module configured to implement the method according to any one of claims. 1–50.
