Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment and network equipment. Background Art

[0002] In order to achieve data transmission, the network usually needs to configure resources. There are two ways to configure resources: dynamic scheduling and unlicensed scheduling. Dynamic scheduling can dynamically configure resources for each transmission to adapt to changes in channel status, but dynamic scheduling requires the receiving end to blindly detect control information, which increases the power consumption of the receiving end; unlicensed scheduling can have the characteristics of one-time configuration and multiple uses, and the parameters configured once will be reused within a fixed time period to reduce signaling overhead.

[0003] However, in actual communication, the terminal device may not use the unlicensed scheduling resources, but the network may not be able to know the unused unlicensed scheduling resources, making it impossible for the network to release the unused unlicensed scheduling resources, ultimately resulting in resource waste.

[0089] 2. Reporting of Transmission Unit Usage Status

[0090]

Authorization-free resource scheduling

[0091] For the resources required for data transmission, the communication system can be configured through two methods: dynamic scheduling and unlicensed scheduling.

[0092] Dynamic scheduling is to dynamically configure resources for each transmission based on the real-time channel status and system requirements, which can adapt to changes in channel status, thereby improving system capacity and efficiency. However, dynamic scheduling requires the receiver to obtain and process control information in real time, which will increase the power consumption of the receiver. At the same time, dynamic scheduling requires more complex algorithms and mechanisms to implement, which may introduce certain delays and computational overhead.

[0093] Unlicensed scheduling is a one-time configuration and multiple-use method, that is, after the initial configuration, subsequent transmissions all use the same parameter configuration, and the same parameter configuration is reused within a certain time interval, so that the resource configuration information does not need to be frequently transmitted and updated, reducing signaling transmission and processing overhead. At the same time, the configuration of unlicensed scheduling resources is periodic, and periodic resources can improve system efficiency and performance.

[0094] In other words, authorization-free scheduling of resources can be understood as no need to schedule / configure resources every time data is transmitted, that is, resources only need to be pre-configured once and are valid periodically.

[0095] The unlicensed scheduling resources may include unlicensed scheduling uplink channel resources and / or unlicensed scheduling downlink channel resources. Among them, the unlicensed scheduling uplink channel resources can be used to carry uplink data of the service; the unlicensed scheduling downlink channel resources can be used to carry downlink data of the service.

[0096] For example, taking the uplink data of a service as an example, since the application in the application layer of the terminal device generates uplink data periodically, the uplink channel resources for unauthorized scheduling are periodic, and the uplink channel resources only need to be configured once and are valid periodically, which is conducive to improving configuration efficiency.

[0097] Optionally, the uplink channel resources for unlicensed scheduling may include configured grant physical uplink shared channel (Configured Grant Physical Uplink Shared Channel, CG-PUSCH) resources; the downlink channel resources for unlicensed scheduling may include semi-persistent scheduling physical downlink shared channel (Semi-Persistent Scheduling Physical Down link Shared Channel, SPS PDSCH) resources.

[0098] CG-PUSCH resources can be understood as uplink channel resources semi-statically configured by the network device for the terminal device. The network device can configure CG-PUSCH resources for the terminal device by configuring the configured grant config information. There are two types of CG-PUSCH resource configuration methods:

[0099] Configured grant Type 1: By configuring the grant configuration information, all parameters related to the CG-PUSCH resource, such as the frequency domain position and period, are configured to the terminal device; among them, the time domain position of the CG-PUSCH resource can be determined by the time domain parameters such as the period. After configuring the CG-PUSCH resource by configuring grant type 1, the CG-PUSCH resource takes effect immediately and does not need to be activated or deactivated.

[0100] Configured grant Type 2: By configuring the grant configuration information, the terminal device is configured with some parameters related to the CG-PUSCH resources, such as the period and the number of HARQ processes. After configuring the CG-PUSCH resources by configuring grant type 2, the network also needs to activate or deactivate through L1 signaling or downlink control information (DCI); the frequency domain position of the CG-PUSCH resources is indicated by DCI, and the time domain position of the CG-PUSCH resources is determined by the period and the time domain parameters provided in the DCI.

[0101] Optionally, the unlicensed scheduling resource may include one or more time domain resources, which may be referred to as a transmission unit. The transmission unit includes a transmission occasion (TO) and / or a repeated transmission occasion. The transmission occasion and the repeated transmission occasion are described in detail below.

[0102]

Transmission timing

[0103] A transmission opportunity may refer to a time segment used to transmit data or signals within a specific time interval, and may also be referred to as a sending opportunity or a transmission opportunity. Thus, a terminal device may use a transmission opportunity to perform a transmission.

[0104] It should be noted that the network will periodically configure the unlicensed scheduling resources, and in each period of the unlicensed scheduling resources, the unlicensed scheduling resources may include one or more transmission opportunities.

[0105] For example, taking the CG-PUSCH resource as an example, Figure 2As shown, in each cycle of the CG-PUSCH resources, the CG-PUSCH resources include three transmission opportunities. Among them, in the first cycle, the CG-PUSCH resources include transmission opportunity 201, transmission opportunity 202 and transmission opportunity 203, and these three transmission opportunities are respectively in time unit n, time unit n+1 and time unit n+2. In the second cycle, the CG-PUSCH resources include transmission opportunity 204, transmission opportunity 205 and transmission opportunity 206, and these three transmission opportunities are respectively in time unit n+5, time unit n+6 and time unit n+7. The time unit can be one of a subframe, a time slot, a symbol, a mini time slot, etc., and there is no specific limitation on this.

[0106] Optionally, each transmission opportunity may be associated with (occupied or used, etc.) a HARQ process, and each HARQ process is associated with a configuration authorization timer. The HARQ processes associated with each transmission opportunity may be the same or different. If the configuration authorization timer associated with a certain HARQ process is running, uplink transmission cannot be performed on the transmission opportunity associated with the HARQ process. In addition, the HARQ process identifier (HARQ process ID) associated with the transmission opportunity may be configured or indicated by the network, and may be determined autonomously by the terminal device.

[0107] Optionally, each transmission opportunity may be associated with (occupied or used, etc.) a redundancy version (RedundancyVersion, RV), and each transmission opportunity may be associated with (occupied or used, etc.) a new data indication (New Data Indicator, NDI).

[0108]

Repeat transmission timing

[0109] It should be noted that the terminal device can perform one transmission at each transmission opportunity. In order to increase the number of transmissions, the network can repeatedly configure a transmission opportunity for multiple times. In this case, each repetition of the transmission opportunity can be called a "repeated transmission opportunity". In this way, multiple repeated transmission opportunities can be used to achieve multiple repeated transmissions of data.

[0110] That is to say, repeated transmission opportunities can be understood as each transmission opportunity can be repeatedly configured multiple times to obtain multiple repeated transmission opportunities, so that data can be repeatedly transmitted multiple times through multiple repeated transmission opportunities to ensure the reliability of business data transmission.

[0111] It is worth noting that the "repeated transmission of data" described in this application is not the retransmission of business data. The repeated transmission of data can be understood as directly transmitting the same data multiple times without considering whether the data failed last time and without considering HARQ-ACK feedback; the retransmission of business data can be understood as judging through HARQ-ACK feedback that the last data transmission failed and needs to be transmitted again.

[0112] For example, taking the CG-PUSCH resource as an example, Figure 3 As shown, in each cycle of CG-PUSCH, the CG-PUSCH resources include two transmission opportunities, and each transmission opportunity includes two repeated transmission opportunities. Among them, in the first cycle, the CG-PUSCH resources include two repeated transmission opportunities of transmission opportunity 301 and two repeated transmission opportunities of transmission opportunity 302, and these four repeated transmission opportunities are respectively in time unit m, time unit m+1, time unit m+3 and time unit m+4. In the second cycle, the CG-PUSCH resources include two repeated transmission opportunities of transmission opportunity 303 and two repeated transmission opportunities of transmission opportunity 304, and these four repeated transmission opportunities are respectively in time unit m+6, time unit m+7, time unit m+9 and time unit m+10. The time unit can be one of a subframe, a time slot, a symbol, a mini time slot, etc., and there is no specific limitation on this.

[0113] It should be noted that each repeated transmission opportunity may be associated with a HARQ process ID, a RV and a NDI, wherein the HARQ process ID associated with all repeated transmission opportunities in the same transmission opportunity may be the same.

[0114] [Available transmission units and unavailable transmission units]

[0115] The grant-free scheduling resources configured by the network device to the terminal device may contain available transmission units and unavailable transmission units. In order to ensure transmission reliability, the terminal device mainly uses the available transmission units to transmit uplink data.

[0116] An available transmission unit refers to a transmission unit that does not overlap with a downlink symbol or a synchronization signal block (SSB), etc. Correspondingly, an unavailable transmission unit refers to a transmission unit that overlaps with a downlink symbol or a synchronization signal block (SSB), etc.

[0117] It should be noted that “overlap” can be understood as having all or part of the same time domain resources.

[0118] Optionally, the available transmission unit includes an available transmission opportunity and / or an available repeated transmission opportunity. Among them, the available transmission opportunity refers to a transmission opportunity that does not overlap with a downlink symbol or SSB, etc.; the available repeated transmission opportunity refers to a repeated transmission opportunity that does not overlap with a downlink symbol or SSB, etc.

[0119] Optionally, the unavailable transmission unit includes an unavailable transmission opportunity and / or an unavailable repeated transmission opportunity, wherein the unavailable transmission opportunity refers to a transmission opportunity overlapping with a downlink symbol or SSB, etc.; the unavailable repeated transmission opportunity refers to a repeated transmission opportunity overlapping with a downlink symbol or SSB, etc.

[0120] [Usage status of available transmission units]

[0121] During actual communication, the terminal device may not use every available transmission unit in the unlicensed scheduling resources, resulting in unused available transmission units.

[0122] Based on this, the present application considers that the terminal device reports the usage status of the available transmission unit to the network device, and the usage status of the available transmission unit can indicate whether the available transmission unit will be used or not. In this way, the network device can release the available transmission unit that will not be used in time according to the usage status of the available transmission unit, thereby improving the system capacity and avoiding resource waste.

[0123] For example, the terminal device may send uplink control information (UCI) to the network device, where the UCI is used to indicate an unused available transmission unit, and the UCI is carried by the available transmission unit. In this way, the terminal device reports the usage status of the available transmission unit by using the UCI. The UCI may be called unused transmission occasion-uplink control information (UTO-UCI).

[0124] In addition, when reporting the usage status of available transmission units, the terminal device will not report the usage status of all available transmission units in the unlicensed scheduling resources, but will use the current available transmission unit to report the usage status of N consecutive available transmission units after the current available transmission unit. The value of N may be network configured, pre-configured, or protocol defined, and there is no specific limitation on this.

[0125] For example, Figure 4As shown, the terminal device sends UCI on the available transmission opportunity 402 of the unlicensed scheduling resource, and the UCI is used to indicate the use status of N (N=4) consecutive available transmission units (i.e., available transmission unit 403, available transmission unit 404, available transmission unit 405, and available transmission unit 405) after the end position of available transmission unit 402, and the value of N is configured by high-level signaling. Among them, the UCI can indicate that available transmission unit 403 and available transmission unit 404 will be used, and available transmission unit 405 and available transmission unit 405 will not be used. In this way, the use status of the N consecutive available transmission units is reported through the UCI carried by the available transmission opportunity 402.

[0126] [Reporting of transmission unit usage status under multiple authorization-free scheduling resource configurations]

[0127] At present, network equipment usually configures only a single unlicensed scheduling resource to the same terminal device, and the single unlicensed scheduling resource includes one or more transmission units. Regarding the reporting of the use status of the transmission unit under the configuration of a single unlicensed scheduling resource, according to the network configuration, the single unlicensed scheduling resource only needs to report the use status of the transmission unit of the single unlicensed scheduling resource.

[0128] However, as network communication scenarios continue to change, network equipment may configure multiple unlicensed scheduling resources for the same terminal device, and each unlicensed scheduling resource includes one or more transmission units. The multiple unlicensed scheduling resources may be in the same cell or in different cells.

[0129] For example, in a carrier aggregation (CA) scenario, the network device will configure multiple unlicensed scheduling resources for the same terminal device, and these unlicensed scheduling resources are associated with different carriers. At the same time, the same carrier will also be associated with one or more unlicensed scheduling resources.

[0130] For another example, in a dual connectivity (DC) scenario, the network device may configure multiple unlicensed scheduling resources for the same terminal device, and these unlicensed scheduling resources are associated with different cells, that is, some unlicensed scheduling resources are associated with the primary cell, and another unlicensed scheduling resource is associated with the secondary cell.

[0131] Regarding the problem of how to report the use status of the transmission unit under the configuration of multiple unlicensed scheduling resources, unlike a single unlicensed scheduling resource, when the terminal device reports the use status of the transmission unit, the terminal device can only use one of the multiple unlicensed scheduling resources to report. At the same time, in addition to reporting the use status of the transmission unit of the authorized scheduling resource, the authorized scheduling resource can also report the use status of the transmission units of other authorized scheduling resources except the authorized scheduling resource.

[0132] It should be noted that the authorized scheduling resource specifically refers to one of multiple unauthorized scheduling resources. It may be configured / indicated by the network, determined autonomously by the terminal device, pre-configured, or a default one among multiple unauthorized scheduling resources (such as the first one, etc.).

[0133] In addition, whether the authorized scheduling resource also reports the transmission unit usage status of the other authorized scheduling resources can be configured / indicated by the network, can be determined autonomously by the terminal device, or can be pre-configured. At the same time, which one or more authorized scheduling resources among the multiple unauthorized scheduling resources the other authorized scheduling resources are can still be configured / indicated by the network, can be determined autonomously by the terminal device, or can be pre-configured.

[0134] For example, the network device configures four unlicensed scheduling resources to the same terminal device, namely, unlicensed scheduling resource 1, unlicensed scheduling resource 2, unlicensed scheduling resource 3, and unlicensed scheduling resource 4. Afterwards, the network device configures / instructs the terminal device to use unlicensed scheduling resource 2 to report the usage status of the transmission unit of unlicensed scheduling resource 2 through high-level signaling (such as RRC signaling, MAC signaling, etc.). In addition, the network device configures / instructs the terminal device to use unlicensed scheduling resource 2 to report the usage status of the transmission units of unlicensed scheduling resource 2 and unlicensed scheduling resource 3 through additional high-level signaling.

[0135] The present application will now specifically describe how to report the use status of a transmission unit under multiple authorization-free scheduling resource configurations through the following multiple schemes, wherein the various schemes may be interrelated and combined, or may be independent of each other.

[0136] [Scheme 1]

[0137] a. Description

[0138] In "Solution 1", the network device configures multiple unlicensed scheduling resources to the same terminal device. Then, the network device can configure / indicate a certain unlicensed scheduling resource among the multiple unlicensed scheduling resources through high-level signaling. In this way, the terminal device can use the licensed scheduling resource to report the transmission unit usage status of the unlicensed scheduling resource.

[0139] For the convenience of distinction and description, the following application takes the grant-free scheduling resource as the "first grant-free scheduling resource" as an example for explanation. After that, there are the following two situations:

[0140] First case:

[0141] In the "first case", when the network device also configures / indicates other unlicensed scheduling resources among the multiple unlicensed scheduling resources through additional high-level signaling, the terminal device can also use the first unlicensed scheduling resource to report the transmission unit usage status of the other unlicensed scheduling resources. The other unlicensed scheduling resources can be one or more unlicensed scheduling resources other than the first unlicensed scheduling resource.

[0142] In this way, during the reporting process, the terminal device sends first information on the first transmission unit of the first authorization-free scheduling resource, and the first information is used to indicate the usage status of the transmission unit of the first authorization-free scheduling resource and the usage status of the transmission unit of the other authorization-free scheduling resources, thereby realizing the reporting of the transmission unit usage status under multiple authorization-free scheduling resource configurations through the first information.

[0143] Second case:

[0144] In the "second case", when the network device does not configure / indicate other unlicensed scheduling resources through additional high-level signaling, the terminal device can only use the first unlicensed scheduling resource to report the usage status of its own transmission unit.

[0145] In this way, during the reporting process, the terminal device sends first information on the first transmission unit of the first unlicensed scheduling resource, and the first information is used to indicate the usage status of the transmission unit of the first unlicensed scheduling resource, thereby realizing the reporting of the transmission unit usage status under multiple unlicensed scheduling resource configurations through the first information.

[0146] It should be noted that the first transmission unit may be an available transmission unit in the first unlicensed scheduling resource used by the terminal device for reporting at the current moment. The first information may be uplink signaling or uplink information used by the terminal device for reporting. For example, the first information may be UCI, UTO-UCI, MAC CE, etc.

[0147] b. Reference time domain interval

[0148] When the terminal device reports the usage status of the transmission unit of the first unlicensed scheduling resource, it will not report the usage status of all available transmission units in the first unlicensed scheduling resource. Therefore, in order to determine which available transmission units' usage status needs to be reported, this application introduces the "first reference time domain interval". The first reference time domain interval can refer to a period of time, and can also be called a "reporting area", "reporting window", "time domain range", "indication interval", etc.

[0149] In this way, for the first unlicensed scheduling resource, the terminal device reports the usage status of the available transmission units of the first unlicensed scheduling resource within the first reference time domain interval.

[0150] Optionally, there are N available transmission units of the first unlicensed scheduling resources after the first transmission unit in the first reference time domain interval. In this way, the terminal device can use the first transmission unit to report the usage status of the N available transmission units of the first unlicensed scheduling resources.

[0151] Optionally, the starting position of the first reference time domain interval may be the end symbol of the first transmission unit, may be the symbol after the end symbol of the first transmission unit, may be the last symbol of the time slot where the end symbol of the first transmission unit is located, may be any symbol between the last symbol in the time slot where the end symbol of the first transmission unit is located and the end symbol, may be the first symbol in the next time slot of the time slot where the end symbol of the first transmission unit is located, or may be any symbol in the next time slot of the time slot where the end symbol of the first transmission unit is located.

[0152] Optionally, the end position of the first reference time domain interval can be the first end symbol (the first end symbol is the end symbol of the last transmission unit among the N first unauthorized scheduling resource transmission units after the first transmission unit), can be the symbol after the first end symbol, can be the last symbol of the time slot where the first end symbol is located, can be any symbol between the last symbol in the time slot where the first end symbol is located and the first end symbol, or can be the first symbol of the next time slot after the time slot where the first end symbol is located.

[0153] Similarly, when the terminal device reports the usage status of the transmission unit of other unlicensed scheduling resources, it will not report the usage status of all available transmission units of each unlicensed scheduling resource in other unlicensed scheduling resources. Therefore, in order to determine which available transmission units need to report their usage status, this application introduces a "second reference time domain interval".

[0154] The second reference time domain interval and the first reference time domain interval have the same starting position and ending position, that is, the second reference time domain interval and the first reference time domain interval are the same reference time domain interval.

[0155] In this way, for other unlicensed scheduling resources, the terminal device reports the usage status of the available transmission units of other unlicensed scheduling resources within the second reference time domain interval.

[0156] Since the second reference time domain interval and the first reference time domain interval are the same reference time domain interval, the present application may determine the available transmission units of other grant-free scheduling resources within the second reference time domain interval in the following manner:

[0157] The start symbol of the available transmission unit or the time slot where the start symbol is located is within the first reference time domain interval; and / or, the end symbol of the available transmission unit or the time slot where the end symbol is located is within the first reference time domain interval.

[0158] The following is an example of the starting position and the ending position of the first reference time domain interval and the second reference time domain interval.

[0159] c. Example

[0160] exist Figure 5 In the case of a subcarrier spacing of 15 kHz, radio frame k and radio frame k+1 each have 10 time slots, and each time slot contains 14 symbols under a normal cyclic prefix (CP).

[0161] The network device configures three grant-free scheduling resources for the same terminal device, namely, grant-free scheduling resource 510, grant-free scheduling resource 520, and grant-free scheduling resource 530, and the following are present:

[0162] ◆In one cycle of the unlicensed scheduling resources 510, the unlicensed scheduling resources 510 include 4 available transmission opportunities, and the 4 available transmission opportunities are respectively in time slot 0, time slot 1, time slot 2 and time slot 3 of the wireless frame k; the end symbol of the available transmission opportunity in time slot 0 is symbol 10; in the next cycle of the unlicensed scheduling resources 510, the unlicensed scheduling resources 510 include 4 available transmission opportunities, and the 4 available transmission opportunities are respectively in time slot 0, time slot 1, time slot 2 and time slot 3 of the wireless frame k+1.

[0163] ◆In one cycle of the unlicensed scheduling resource 520, the unlicensed scheduling resource 520 includes 1 available transmission opportunity in the time slot of the wireless frame k; in the next cycle of the unlicensed scheduling resource 520, the unlicensed scheduling resource 510 includes 1 available transmission opportunity in the time slot 7 of the wireless frame k, and so on.

[0164] ◆In one cycle of the unlicensed scheduling resources 530, the unlicensed scheduling resources 530 include 4 repeated transmission opportunities, and the 4 repeated transmission opportunities are respectively in time slot 2, time slot 3, time slot 4 and time slot 5 of wireless frame k; in the next cycle of the unlicensed scheduling resources 530, the unlicensed scheduling resources 530 include 4 repeated transmission opportunities, and the 4 repeated transmission opportunities are respectively in time slot 0, time slot 1, time slot 2 and time slot 3 of wireless frame k+1, and so on.

[0165] Afterwards, for reporting the usage status of the transmission unit under the three authorization-free scheduling resource configurations, the network device is configured as follows:

[0166] ◆Configure the terminal device to use the unlicensed scheduling resource 510 to report the usage status of the transmission unit of the unlicensed scheduling resource 510,

[0167] Among the three grant-free scheduling resources, only the grant-free scheduling resource 510 is configured to be used;

[0168] ◆Configure the terminal device to use the unlicensed scheduling resource 510 to report the usage status of the transmission units of the unlicensed scheduling resource 520 and the unlicensed scheduling resource 530;

[0169] ◆The value of N is 3.

[0170] Then, in the reporting process, the terminal device sends the first information at the available transmission opportunity in time slot 0 of wireless frame k. At this time, the end symbol of the available transmission opportunity is symbol 10 in time slot 0 of wireless frame k, the time slot where the end symbol of the available transmission opportunity is located is time slot 0 of wireless frame k, and the next time slot after the time slot where the end symbol of the available transmission opportunity is located is time slot 1. At this time, the starting position and the ending position of the first reference time domain interval are as follows: Figure 6 shown.

[0171] exist Figure 6 In (a), since the value of N is 3, there are N=3 available transmission units after the available transmission opportunity 611 in the first reference time domain interval. The starting position of the first reference time domain interval is the end symbol of the available transmission opportunity 611, and the end position of the first reference time domain interval is the end symbol of the available transmission opportunity 614.

[0172] exist Figure 6In (b), since the value of N is 3, there are N=3 available transmission units after the available transmission opportunity 611 in the first reference time domain interval. The starting position of the first reference time domain interval is the last symbol of the time slot where the end symbol of the available transmission opportunity 611 is located (i.e., time slot 0), and the end position of the first reference time domain interval is the last symbol of the time slot where the end symbol of the available transmission opportunity 611 is located (i.e., time slot 3).

[0173] exist Figure 6 In (c), since the value of N is 3, there are N=3 available transmission units after the available transmission opportunity 611 in the first reference time domain interval. The starting position of the first reference time domain interval is the symbol after the end symbol of the available transmission opportunity 611, and the end position of the first reference time domain interval is the symbol after the end symbol of the available transmission opportunity 611.

[0174] In this way, the unlicensed scheduling resource 510 has three available transmission opportunities (i.e., available transmission opportunity 612, available transmission opportunity 613, and available transmission opportunity 614) in the first reference time domain interval. The unlicensed scheduling resource 520 has one available transmission opportunity (i.e., available transmission opportunity 621) in the first reference time domain interval. The unlicensed scheduling resource 530 has one available repeated transmission opportunity (i.e., available repeated transmission opportunity 631) in the first reference time domain interval, and one of the starting symbols, the time slot where the starting symbol is located, or the time slot where the ending symbol is located of the available repeated transmission opportunity (i.e., available repeated transmission opportunity 632) is in the first reference time domain interval.

[0175] Ultimately, the first information is used to indicate the usage status of available transmission opportunity 612, the usage status of available transmission opportunity 613, the usage status of available transmission opportunity 614, the usage status of available transmission opportunity 621, the usage status of available repeated transmission opportunity 631, and the usage status of available repeated transmission opportunity 632.

[0176] d. Usage Information

[0177] In the case where the terminal device only needs to report the transmission unit usage status of the first unlicensed scheduling resource through the first information, the first information may include first usage information corresponding to the first unlicensed scheduling resource. The first usage information may be used to indicate the usage status of the available transmission units of the first unlicensed scheduling resource within the first reference time domain interval.

[0178] For example, in Figure 6 In the embodiment, the first information includes first usage information corresponding to the unlicensed scheduling resource 510, and the first usage information is used to indicate the usage status of the available transmission opportunity 612, the usage status of the available transmission opportunity 613, and the usage status of the available transmission opportunity 614.

[0179] Optionally, the first usage information is a bitmap, and the number of bits of the bitmap is the number of available transmission units of the first unlicensed scheduling resource in the first reference time domain interval (ie, the third number or N).

[0180] In this way, each bit in the bitmap corresponds one-to-one to an available transmission unit of the first unlicensed scheduling resource in the first reference time domain interval, so that the use status of the corresponding available transmission unit is indicated by the value of the bit. If the value of the bit is "0", the available transmission unit corresponding to the bit will not be used; if the value of the bit is "1", the available transmission unit corresponding to the bit will be used. Conversely, if the value of the bit is "0", the available transmission unit corresponding to the bit will be used; if the value of the bit is "0", the available transmission unit corresponding to the bit will not be used.

[0181] For example, in Figure 6 In the example, the first usage information is a 3-bit bitmap. The bitmap is "011", which indicates that the available transmission opportunity 612 will be used, and the available transmission opportunity 613 and the available transmission opportunity 614 will not be used.

[0182] In the case where the terminal device also needs to report the transmission unit usage status of other unlicensed scheduling resources through the first information, the first information may include the first usage information corresponding to the first unlicensed scheduling resource and the second usage information corresponding to each of the other unlicensed scheduling resources. The second usage information may be used to indicate the usage status of the available transmission unit of the unlicensed scheduling resource corresponding to the second usage information within the second reference time domain interval.

[0183] For example, in Figure 6 In the example, the first information includes first usage information corresponding to the unlicensed scheduling resource 510, second usage information corresponding to the unlicensed scheduling resource 520, and second usage information corresponding to the unlicensed scheduling resource 530. The second usage information corresponding to the unlicensed scheduling resource 520 is used to indicate the usage status of the available transmission opportunity 621; the second usage information corresponding to the unlicensed scheduling resource 530 is used to indicate the usage status of the available repeated transmission opportunity 631 and the usage status of the available repeated transmission opportunity 632.

[0184] Optionally, the second usage information is a bitmap, and the number of bits of the bitmap is the number of available transmission units (ie, the first number) of the unlicensed scheduling resources corresponding to the second usage information within the second reference time domain interval.

[0185] In this way, each bit in the bitmap corresponds one-to-one to the available transmission unit of the unlicensed scheduling resource corresponding to the second usage information within the second reference time domain interval, so that the usage status of the corresponding available transmission unit is indicated by the value of the bit. If the value of the bit is "0", the available transmission unit corresponding to the bit will not be used; if the value of the bit is "1", the available transmission unit corresponding to the bit will be used. Conversely, if the value of the bit is "0", the available transmission unit corresponding to the bit will be used; if the value of the bit is "0", the available transmission unit corresponding to the bit will not be used.

[0186] For example, in Figure 6 In the example, the second usage information corresponding to the grant-free scheduling resource 520 is a 1-bit bitmap, and the bitmap is “1”. The second usage information corresponding to the grant-free scheduling resource 530 is a 2-bit bitmap, and the bitmap is “00”.

[0187] Optionally, the second usage information is a bitmap, and the number of bits of the bitmap is the number of RVs of 0 associated with available transmission units of the unlicensed scheduling resources corresponding to the second usage information within the second reference time domain interval (ie, the second number).

[0188] It should be noted that each available transmission unit may be associated with an RV. When the RV is 0, this indicates that the available transmission unit associated with the RV is an initial transmission unit, and the data carried by the initial transmission unit is transmitted for the first time or for the first time. Therefore, when the number of bits of the second usage information is the number of RVs associated with the available transmission units of the unlicensed scheduling resources corresponding to the second usage information in the second reference time domain interval is 0, this indicates that the terminal device only needs to report the usage status of the initial transmission unit in the second reference time domain interval.

[0189] For example, in Figure 6 In the embodiment, if the RV associated with the repeated transmission opportunity 631 is 0, and the RV associated with the repeated transmission opportunity 632 is not 0, the second usage information corresponding to the grant-free scheduling resource 530 is a 1-bit bitmap.

[0190] e. Order of usage information within the first information

[0191] In the case where the first information includes the first usage information and the second usage information corresponding to each of the other unlicensed scheduling resources, the first usage information and the second usage information have a certain sorting order in the first information. The sorting order may be configured / indicated by the network device, may be determined autonomously by the terminal device, may be pre-configured, or may be specified by the protocol.

[0192] Optionally, the first usage information and the second usage information corresponding to each authorization-free scheduling resource in the other authorization-free scheduling resources are sequentially sorted in the first information according to the order of the authorization-free scheduling resource indexes.

[0193] The order of the unlicensed scheduling resource indexes may be from low to high, or from high to low. In this way, the network device can receive the usage information in sequence according to the unlicensed scheduling resource indexes.

[0194] For example, taking the order of the authorization-free scheduling resource index from low to high as an example, in Figure 6 In the first information, the unlicensed scheduling resource 510, the unlicensed scheduling resource 520 and the unlicensed scheduling resource 530 are indexed from low to high. In this way, in the first information, the first usage information is ranked first, followed by the second usage information corresponding to the unlicensed scheduling resource 520, and finally the second usage information corresponding to the unlicensed scheduling resource 530. At this time, if the first usage information is "011", the second usage information corresponding to the unlicensed scheduling resource 520 is "1", and the second usage information corresponding to the unlicensed scheduling resource 530 is "00", then the order of these usage information included in the first information is "011100".

[0195] Optionally, the first usage information is positioned in the first information before the second usage information corresponding to each authorization-free scheduling resource in other authorization-free scheduling resources; the second usage information corresponding to each authorization-free scheduling resource in other authorization-free scheduling resources is sorted in the first information in the order of the authorization-free scheduling resource index.

[0196] Among them, the order of the grant-free scheduling resource indexes can be the order of the grant-free scheduling resource indexes from low to high, or can be the order of the grant-free scheduling resource indexes from high to low.

[0197] In this way, since the network device indicates the first unlicensed scheduling resource from multiple unlicensed scheduling resources for reporting, when the first usage information is ranked first, the network device can preferentially receive the first usage information and preferentially know the transmission unit usage status of the first unlicensed scheduling resource.

[0198] For example, taking the example of sorting the usage information in descending order according to the index of the unlicensed scheduling resource, Figure 6In the first information, the unlicensed scheduling resource 510, the unlicensed scheduling resource 520 and the unlicensed scheduling resource 530 are indexed from low to high. In this way, in the first information, the first usage information is ranked first, followed by the second usage information corresponding to the unlicensed scheduling resource 530, and finally the second usage information corresponding to the unlicensed scheduling resource 520. If the first usage information is "011", the second usage information corresponding to the unlicensed scheduling resource 520 is "1", and the second usage information corresponding to the unlicensed scheduling resource 530 is "00", then the order of these usage information included in the first information is "011001".

[0199] [Scheme 2]

[0200] a. Description

[0201] It should be noted that the difference between "Scheme 2" and the above-mentioned "Scheme 1" is that the end position of the first reference time domain interval in "Scheme 2" is different from the end position of the first reference time domain interval in "Scheme 1". In addition, the rest of the content of "Scheme 2" can refer to the content of "Scheme 1" above, which will not be repeated here. The first reference time domain interval is described in detail below.

[0202] Optionally, the end position of the first reference time domain interval can be the first starting symbol (the first starting symbol is the starting symbol of the last transmission unit among the N+1 transmission units of the first unlicensed scheduling resources after the first transmission unit), can be the symbol before the first starting symbol, can be the first symbol of the time slot where the first starting symbol is located, or can be any symbol between the first symbol and the first starting symbol in the time slot where the first starting symbol is located.

[0203] In addition, the number of available transmission units of the first authorization-free scheduling resource in the first reference time domain interval in "Scheme 2" is the same as that in "Scheme 1", such as the N available transmission units of the first authorization-free scheduling resources after the first transmission unit. However, since the end position of the first reference time domain interval in "Scheme 2" is different from that in "Scheme 1", and the second reference time domain interval has the same starting position and end position as the first reference time domain interval, the end position of the second reference time domain interval in "Scheme 2" is different from that in "Scheme 1". In this way, the number of available transmission units of other authorization-free scheduling resources in the second reference time domain interval in "Scheme 2" is different from that in "Scheme 1".

[0204] The following is an example of the first reference time domain interval and the second reference time domain interval in "Solution 2".

[0205] b. Example

[0206] exist Figure 5 On the basis of Figure 7As shown. Figure 7 In (a), since the value of N is 3, and there are 3 available transmission units after the available transmission opportunity 711 in the first reference time domain interval, the starting position of the first reference time domain interval is the end symbol of the available transmission opportunity 711, and the end position of the first reference time domain interval is the starting symbol of the available transmission opportunity 715.

[0207] exist Figure 7 In (b), since the value of N is 3 and there are 3 available transmission units after the available transmission opportunity 711 in the first reference time domain interval, the starting position of the first reference time domain interval is the last symbol of the time slot where the available transmission opportunity 711 is located (i.e., time slot 0 of wireless frame k), and the end position of the first reference time domain interval is the first symbol of the time slot where the starting symbol of the available transmission opportunity 715 is located (i.e., time slot 0 of wireless frame k+1).

[0208] exist Figure 7 In (c), since the value of N is 3, and there are 3 available transmission units after the available transmission opportunity 711 in the first reference time domain interval, the starting position of the first reference time domain interval is the symbol after the end symbol of the available transmission opportunity 711, and the end position of the first reference time domain interval is the symbol before the start symbol of the available transmission opportunity 715.

[0209] In this way, the grant-free scheduling resource 510 has three available transmission opportunities (i.e., available transmission opportunity 712, available transmission opportunity 713, and available transmission opportunity 714) in the first reference time domain interval. The grant-free scheduling resource 520 has two available transmission opportunities (i.e., available transmission opportunity 721 and available transmission opportunity 722) in the first reference time domain interval. The grant-free scheduling resource 530 has four available repeated transmission opportunities (i.e., available repeated transmission opportunity 731, available repeated transmission opportunity 732, available repeated transmission opportunity 733, and available repeated transmission opportunity 734) in the first reference time domain interval.

[0210] It can be seen that the first information is used to indicate the usage status of available transmission opportunity 712, the usage status of available transmission opportunity 713, the usage status of available transmission opportunity 714, the usage status of available transmission opportunity 721, the usage status of available transmission opportunity 722, the usage status of available repeated transmission opportunity 731, the usage status of available repeated transmission opportunity 732, the usage status of available repeated transmission opportunity 733 and the usage status of available repeated transmission opportunity 734.

[0211] Finally, when the usage information is a bitmap, the number of bits of the first usage information is 3, the number of bits of the second usage information corresponding to the unlicensed scheduling resource 520 is 2, and the number of bits of the second usage information corresponding to the unlicensed scheduling resource 530 is 4.

[0212] If the usage information is sorted in sequence according to the index of the unlicensed scheduling resource from high to low, and the unlicensed scheduling resource 510, the unlicensed scheduling resource 520 and the unlicensed scheduling resource 530 are each indexed from low to high, then in the first information, the first usage information is ranked first, followed by the second usage information corresponding to the unlicensed scheduling resource 530, and finally the second usage information corresponding to the unlicensed scheduling resource 520.

[0213] [Scheme 3]

[0214] a. Description

[0215] It should be noted that the difference between "Scheme Three" and the above-mentioned "Scheme One" and "Scheme Two" is that: "Scheme One" and "Scheme Two" sort the usage information in the first information in the order of the unauthorized scheduling resource index, but "Scheme Three" sorts the usage information in the first information in the order of the time slot index within the first reference time domain interval. In addition, the rest of the content of "Scheme Three" can be found in the above-mentioned "Scheme One" and "Scheme Two" and will not be repeated here. The "usage information" and "sorting of usage information in the first information" in "Scheme Three" are explained in detail below.

[0216] b. Usage Information

[0217] In the case where the terminal device only needs to report the transmission unit usage status of the first unlicensed scheduling resource through the first information, the first information may include third usage information corresponding to at least one time slot in the first reference time domain interval. The third usage information may be used to indicate the usage status of the available transmission unit of the first unlicensed scheduling resource in the time slot corresponding to the third usage information.

[0218] It should be noted that the first information needs to include which time slots in the first reference time domain interval correspond to the third usage information, and this application needs to determine whether there are available transmission units that need to be reported in the time slot. When there are available transmission units that need to be reported in a time slot in the first reference time domain interval, the first information includes the third usage information corresponding to the time slot.

[0219] For example, in Figure 6 In the first reference time domain interval, the first reference time domain interval includes time slot 1, time slot 2 and time slot 3 of the wireless frame k. There is an available transmission opportunity 612 in time slot 1, an available transmission opportunity 613 in time slot 2, and an available transmission opportunity 614 in time slot 3.

[0220] In this way, the first information includes the third usage information corresponding to time slot 1, the third usage information corresponding to time slot 2, and the third usage information corresponding to time slot 3. The third usage information corresponding to time slot 1 is used to indicate the usage status of the available transmission opportunity 612; the third usage information corresponding to time slot 2 is used to indicate the usage status of the available transmission opportunity 613; and the third usage information corresponding to time slot 3 is used to indicate the usage status of the available transmission opportunity 614.

[0221] For example, in Figure 7 In the first reference time domain interval, the first reference time domain interval includes time slots 1 to 9 of wireless frame k. However, only time slots 1, 2, and 3 have available transmission units to be reported. Among them, time slot 1 has available transmission opportunity 712, time slot 2 has available transmission opportunity 713, and time slot 3 has available transmission opportunity 714.

[0222] In this way, the first information includes the third usage information corresponding to time slot 1, the third usage information corresponding to time slot 2, and the third usage information corresponding to time slot 3. The third usage information corresponding to time slot 1 is used to indicate the usage status of the available transmission opportunity 712; the third usage information corresponding to time slot 2 is used to indicate the usage status of the available transmission opportunity 713; and the third usage information corresponding to time slot 3 is used to indicate the usage status of the available transmission opportunity 714.

[0223] In the case where the terminal device also needs to report the transmission unit usage status of other unlicensed scheduling resources through the first information, the first information may include third usage information corresponding to at least one time slot in the first reference time domain interval. The third usage information may be used to indicate the usage status of the available transmission unit of the first unlicensed scheduling resource in the time slot corresponding to the third usage information and the usage status of the available transmission unit of each unlicensed scheduling resource in other unlicensed scheduling resources in the time slot corresponding to the third usage information.

[0224] For example, in Figure 6 In the first reference time domain interval, the first reference time domain interval includes time slot 1, time slot 2 and time slot 3 of wireless frame k. Among them, time slot 1 has available transmission opportunity 612 and available transmission opportunity 621; time slot 2 has available transmission opportunity 613 and repeated available transmission opportunity 631; time slot 3 has available transmission opportunity 614 and repeated available transmission opportunity 632.

[0225] In this way, the first information includes the third usage information corresponding to time slot 1, the third usage information corresponding to time slot 2, and the third usage information corresponding to time slot 3. The third usage information corresponding to time slot 1 is used to indicate the usage status of available transmission opportunity 612 and the usage status of available transmission opportunity 621; the third usage information corresponding to time slot 2 is used to indicate the usage status of available transmission opportunity 613 and the usage status of repeated available transmission opportunity 631; the third usage information corresponding to time slot 3 is used to indicate the usage status of available transmission opportunity 614 and the usage status of repeated available transmission opportunity 632.

[0226] For example, in Figure 7 In the first reference time domain interval, the first reference time domain interval includes time slots 1 to 9 of radio frame k. However, only time slots 1, 2, 3, 4, 5, and 7 have available transmission units that need to be reported. Among them, time slot 1 has available transmission opportunities 712 and available transmission opportunities 721; time slot 2 has available transmission opportunities 713 and repeated available transmission opportunities 731; time slot 3 has available transmission opportunities 714 and repeated available transmission opportunities 732; time slot 4 has repeated available transmission opportunities 733; time slot 5 has repeated available transmission opportunities 734, and time slot 7 has available transmission opportunities 722.

[0227] In this way, the first information includes the third usage information corresponding to time slot 1, the third usage information corresponding to time slot 2, the third usage information corresponding to time slot 3, the third usage information corresponding to time slot 4, the third usage information corresponding to time slot 5, and the third usage information corresponding to time slot 7. The third usage information corresponding to time slot 1 is used to indicate the usage status of available transmission opportunity 712 and the usage status of available transmission opportunity 721; the third usage information corresponding to time slot 2 is used to indicate the usage status of available transmission opportunity 713 and the usage status of repeated available transmission opportunity 731; the third usage information corresponding to time slot 3 is used to indicate the usage status of available transmission opportunity 714 and the usage status of repeated available transmission opportunity 732; the third usage information corresponding to time slot 4 is used to indicate the usage status of repeated available transmission opportunity 733; the third usage information corresponding to time slot 5 is used to indicate the usage status of repeated available transmission opportunity 734; and the third usage information corresponding to time slot 7 is used to indicate the usage status of available transmission opportunity 722.

[0228] Optionally, the third usage information is a bit map, the number of bits of the bit map being the sum of the number of available transmission units of the first unlicensed scheduling resource in the same time slot corresponding to the third usage information and the number of available transmission units of each of the other unlicensed scheduling resources in the same time slot.

[0229] In this way, each bit in the bitmap corresponds to an available transmission unit of each of the first unlicensed scheduling resource and other unlicensed scheduling resources in the same time slot, so that the use status of the corresponding available transmission unit is indicated by the value of the bit. If the value of the bit is "0", the available transmission unit corresponding to the bit will not be used; if the value of the bit is "1", the available transmission unit corresponding to the bit will be used. On the contrary, if the value of the bit is "0", the available transmission unit corresponding to the bit will be used; if the value of the bit is "0", the available transmission unit corresponding to the bit will not be used.

[0230] For example, in Figure 6 In the embodiment, the third usage information corresponding to time slot 1 is a 2-bit bitmap; the third usage information corresponding to time slot 2 is a 2-bit bitmap; and the third usage information corresponding to time slot 3 is a 2-bit bitmap.

[0231] For example, in Figure 7 In the figure, the third usage information corresponding to time slot 1 is a 2-bit bitmap; the third usage information corresponding to time slot 2 is a 2-bit bitmap; the third usage information corresponding to time slot 3 is a 2-bit bitmap; the third usage information corresponding to time slot 4 is a 1-bit bitmap; the third usage information corresponding to time slot 5 is a 1-bit bitmap; and the third usage information corresponding to time slot 7 is a 1-bit bitmap.

[0232] d. The order of usage information in the first information

[0233] In the case where the first information includes third usage information corresponding to at least one time slot in the first reference time domain interval, the third usage information has a certain sorting order in the first information. The sorting order may be configured / indicated by the network device, may be determined autonomously by the terminal device, may be pre-configured, or may be specified by the protocol.

[0234] Specifically, the third usage information corresponding to at least one time slot in the first reference time domain interval is sequentially sorted in the first information according to the order of the time slot index. The order of the time slot index may be an order from low to high, or an order from high to low. In this way, the network device can receive the usage information sequentially according to the time slot index.

[0235] For example, in Figure 6 In the first information, if the time slot index is sorted from low to high, the third usage information corresponding to time slot 1 is at the front, followed by the third usage information corresponding to time slot 2, and finally the third usage information corresponding to time slot 3.

[0236] [Scheme 4]

[0237] a. Description

[0238] It should be noted that the difference between "Scheme 4" and the above-mentioned "Scheme 1" to "Scheme 3" is that in "Scheme 1" to "Scheme 3", the carrier associated with each of the multiple unlicensed scheduling resources configured by the network device for the same terminal device is the same, that is, one carrier is associated with multiple unlicensed scheduling resources, but in "Scheme 4", the carrier associated with each of the multiple unlicensed scheduling resources configured by the network device for the same terminal device is different, that is, different carriers are associated with different unlicensed scheduling resources.

[0239] For example, in Figure 5 In the example, the grant-free scheduling resource 510 and the grant-free scheduling resource 520 are associated with carrier 1, but the grant-free scheduling resource 530 is associated with carrier 2.

[0240] In addition, the rest of the contents of "Scheme 4" can be found in the contents of the above-mentioned "Scheme 1" to "Scheme 3", which will not be repeated here.

[0241] It should be noted that in "Solution 4", for multiple unlicensed scheduling resources configured by the network device, the network device can configure / indicate which carrier is associated with which unlicensed scheduling resource (i.e., the first unlicensed scheduling resource) through high-level signaling for reporting. In addition, the network device can also configure / indicate which carriers or other unlicensed scheduling resources associated with the first unlicensed scheduling resource can also be reported through additional high-level signaling.

[0242] In addition, the order of the usage information in the first information in "Scheme 4" is not only performed in the order of the unlicensed scheduling resource index in "Scheme 1" and "Scheme 2", or in the order of the time slot index in the first reference time domain interval in "Scheme 3", but also needs to consider the order of the carrier index. The following is a detailed description.

[0243] b. Order of usage information within the first information

[0244] In the case where the first information includes the first usage information and the second usage information corresponding to each of the other unlicensed scheduling resources, the sorting order of the first usage information and the second usage information in the first information may be configured / indicated by the network device, may be determined autonomously by the terminal device, may be pre-configured, or may be specified by the protocol. The following two methods are described.

[0245] In "method 1", the first usage information and the second usage information may be sequentially sorted in the first information according to the order of the carrier index and then according to the order of the unlicensed scheduling resource index associated with the same carrier index. In this way, the network device can receive the usage information sequentially according to the carrier index and then according to the unlicensed scheduling resource index.

[0246] The order of the carrier index may be from low to high, or from high to low. The order of the unlicensed scheduling resource index associated with the same carrier index may be from low to high, or from high to low.

[0247] In "method 2", the first usage information may be arranged before the second usage information in the first information; the second usage information may be arranged in the first information in the order of the carrier index and then in the order of the unlicensed scheduling resource index associated with the same carrier index. In this way, when the first usage information is arranged at the front, the network device can receive the first usage information first, and obtain the transmission unit usage status of the first unlicensed scheduling resource first.

[0248] For example, in Figure 6 In the figure, the unlicensed scheduling resource 510, the unlicensed scheduling resource 520 and the unlicensed scheduling resource 530 are indexed from low to high respectively; the unlicensed scheduling resource 510 and the unlicensed scheduling resource 520 are associated with carrier 2, the unlicensed scheduling resource 530 is associated with carrier 1, and the index of carrier 2 is greater than the index of carrier 1.

[0249] In this way, taking the order of the carrier index from low to high and then the order of the unlicensed scheduling resource index associated with the same carrier index from high to low as an example, if "method 1" is followed, in the first information, the second usage information corresponding to the unlicensed scheduling resource 530 is ranked first, followed by the second usage information corresponding to the unlicensed scheduling resource 520, and finally the first usage information. At this time, if the first usage information is "011", the second usage information corresponding to the unlicensed scheduling resource 520 is "1", and the second usage information corresponding to the unlicensed scheduling resource 530 is "00", the usage information included in the first information is ranked "001011".

[0250] If "method 2" is used, in the first information, the first usage information is ranked first, followed by the second usage information corresponding to the unlicensed scheduling resource 530, and finally the second usage information corresponding to the unlicensed scheduling resource 520. At this time, if the first usage information is "011", the second usage information corresponding to the unlicensed scheduling resource 520 is "1", and the second usage information corresponding to the unlicensed scheduling resource 530 is "00", then the usage information included in the first information is ranked "011001".

[0251] [Scheme 5]

[0252] a. Description

[0253] It should be noted that the difference between "Scheme 5" and the above-mentioned "Scheme 4" is that: "Scheme 4" sorts the usage information in the first information first according to the order of carrier index and then according to the order of unauthorized scheduling resource index associated with the same carrier index, but "Scheme 5" sorts the usage information in the first information first according to the order of carrier index and then according to the order of time slot index associated with the same carrier index.

[0254] In addition, the rest of the contents of "Solution 5" can refer to the contents of "Solution 1" to "Solution 4" above, and will not be repeated here. The "ranking of usage information in the first information" in "Solution 5" is specifically explained below.

[0255] b. The order of usage information in the first information

[0256] In the case where the first information includes third usage information corresponding to at least one time slot within the first reference time domain interval, the sorting order of these third usage information in the first information may be configured / indicated by the network device, may be determined autonomously by the terminal device, may be pre-configured, or may be specified by the protocol.

[0257] Specifically, the third usage information corresponding to at least one time slot in the first reference time domain interval is sequentially sorted in the first information according to the order of carrier indexes and then according to the order of time slot indexes associated with the same carrier index.

[0258] The order of the carrier index may be from low to high, or from high to low. The order of the time slot index associated with the same carrier index may be from low to high, or from high to low. In this way, the network device can receive the usage information in sequence first according to the carrier index and then according to the time slot index.

[0259] For example, in Figure 6In the example, the unlicensed scheduling resource 510 and the unlicensed scheduling resource 520 are associated with carrier 2, the unlicensed scheduling resource 530 is associated with carrier 1, and the index of carrier 2 is greater than the index of carrier 1.

[0260] In this way, taking the order of carrier index from low to high and then the order of time slot index associated with the same carrier index from low to high as an example, in the first information, the third usage information corresponding to time slot 2 associated with carrier 1 is ranked first, followed by the third usage information corresponding to time slot 3 associated with carrier 1, followed by the third usage information corresponding to time slot 1 associated with carrier 2, the third usage information corresponding to time slot 2 associated with carrier 2, and finally the third usage information corresponding to time slot 3 associated with carrier 2.

[0261] Among them, the third usage information corresponding to time slot 2 associated with carrier 1 is used to indicate the usage status of repeated transmission opportunity 631; the third usage information corresponding to time slot 3 associated with carrier 1 is used to indicate the usage status of repeated transmission opportunity 632; the third usage information corresponding to time slot 1 associated with carrier 2 is used to indicate the usage status of transmission opportunity 612 and the usage status of transmission opportunity 621; the third usage information corresponding to time slot 2 associated with carrier 2 is used to indicate the usage status of transmission opportunity 613; the third usage information corresponding to time slot 3 associated with carrier 2 is used to indicate the usage status of transmission opportunity 614.

[0262] [Scheme 6]

[0263] It should be noted that the difference between "Scheme 6" and the above-mentioned "Schemes 1" to "Schemes 5" is that in "Schemes 1" to "Schemes 5", only one of the multiple unlicensed scheduling resources is configured to be used for reporting, while in "Scheme 6", multiple unlicensed scheduling resources are configured to be used for reporting. However, in the actual reporting process, the terminal device can only use one of the unlicensed scheduling resources to report, and which unlicensed scheduling resource the terminal device uses can be configured by the network or determined autonomously by the terminal device, and there is no specific restriction on this.

[0264] In addition, the rest of the contents of "Plan 6" can be found in the contents of the above-mentioned "Plan 1" to "Plan 5", which will not be repeated here.

[0265] For example, in Figure 5 In FIG. 5 , the network device configures three unlicensed scheduling resources for the same terminal device, namely, unlicensed scheduling resource 510, unlicensed scheduling resource 520, and unlicensed scheduling resource 530. At the same time, in addition to configuring that unlicensed scheduling resource 510 can be used for reporting, the network device also configures that unlicensed scheduling resource 520 can also be used for reporting.

[0266] [Scheme 7]

[0267] a. Description

[0268] It should be noted that the difference between "Scheme 7" and the above-mentioned "Schemes 1 to 6" is that:

[0269] The second reference time domain interval in "Scheme 1" to "Scheme 6" has the same starting position and ending position as the first reference time domain interval, but the second reference time domain interval in "Scheme 7" has the same starting position as the first reference time domain interval but has a different ending position.

[0270] In addition, the number of available transmission units of the unlicensed scheduling resources corresponding to the second usage information in "Scheme 1" to "Scheme 6" in the second reference time domain interval is not necessarily equal to the number of transmission units of the first unlicensed scheduling resources in the first reference time domain interval, but the number of available transmission units of the unlicensed scheduling resources corresponding to the second usage information in "Scheme 7" in the second reference time domain interval is equal to the number of transmission units of the first unlicensed scheduling resources in the first reference time domain interval (i.e., the third number or N).

[0271] In addition, the rest of the content of "Scheme 7" can refer to the contents of the above-mentioned "Scheme 1" to "Scheme 6", which will not be repeated here. The end position of the second usage information and the second reference time domain interval is specifically described below.

[0272] b. Second usage information

[0273] In the case where the first information may include the first usage information corresponding to the first unlicensed scheduling resource and the second usage information corresponding to each of the other unlicensed scheduling resources, since the number of available transmission units of the unlicensed scheduling resource corresponding to the second usage information in the second reference time domain interval (i.e., the third number or N) is equal to the number of transmission units of the first unlicensed scheduling resource in the first reference time domain interval, if the second usage information is a bitmap, the number of bits of the bitmap is the third number or N. In this way, each bit in the bitmap corresponds one-to-one to the available transmission unit of the unlicensed scheduling resource corresponding to the second usage information in the second reference time domain interval, so that the usage status of the corresponding available transmission unit is indicated by the value of the bit.

[0274] c. Second reference time domain interval

[0275] In "Solution 7", there are N other available transmission units of unlicensed scheduling resources after the first transmission unit in the second reference time domain interval. In this way, the terminal device can use the first transmission unit to report the usage status of the N other available transmission units of unlicensed scheduling resources.

[0276] Optionally, the end position of the second reference time domain interval can be the second end symbol (the second end symbol is the end symbol of the last transmission unit among the N other transmission units of the unlicensed scheduling resources after the first transmission unit), can be the symbol after the second end symbol, can be the last symbol of the time slot where the second end symbol is located, can be any symbol between the last symbol in the time slot where the second end symbol is located and the second end symbol, or can be the first symbol of the time slot next to the time slot where the second end symbol is located.

[0277] For example, in Figure 5 On the basis of Figure 8 As shown. Figure 8 In (a), since the value of N is 3, there are N=3 available transmission units after the available transmission opportunity 811 in the second reference time domain interval corresponding to the unlicensed scheduling resource 520. The starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the end symbol of the available transmission opportunity 811, and the end position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the end symbol of the available transmission opportunity 823.

[0278] Similarly, in Figure 8 In (a), the second reference time domain interval corresponding to the unlicensed scheduling resource 530 has N=3 available transmission units after the available transmission opportunity 811. The starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the end symbol of the available transmission opportunity 811, and the end position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the end symbol of the available repeated transmission opportunity 833.

[0279] exist Figure 8 In (b), the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the last symbol of the time slot (i.e., time slot 0) where the end symbol of the available transmission opportunity 811 is located, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the last symbol of the time slot (i.e., time slot 3) where the end symbol of the available transmission opportunity 823 is located. Similarly, the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the last symbol of the time slot (i.e., time slot 0) where the end symbol of the available transmission opportunity 811 is located, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the last symbol of the time slot (i.e., time slot 4) where the end symbol of the available repeated transmission opportunity 833 is located.

[0280] exist Figure 8In (c), the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the symbol after the end symbol of the available transmission opportunity 811, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the symbol after the end symbol of the available transmission opportunity 823. Similarly, the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the symbol after the end symbol of the available transmission opportunity 811, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the symbol after the end symbol of the available repeated transmission opportunity 833.

[0281] Optionally, the end position of the second reference time domain interval may be a second starting symbol (the second starting symbol is the starting symbol of the last transmission unit among the N+1 other transmission units of the unlicensed scheduling resources after the first transmission unit), may be the symbol before the second starting symbol, may be the first symbol of the time slot where the second starting symbol is located, may be the first symbol of the time slot where the second starting symbol is located, or may be any symbol between the first symbol in the time slot where the second starting symbol is located and the second starting symbol.

[0282] For example, in Figure 5 On the basis of Fig. 9 As shown. Fig. 9 In (a), since the value of N is 3, there are N=3 available transmission units after the available transmission opportunity 911 in the second reference time domain interval corresponding to the unlicensed scheduling resource 520. The starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the end symbol of the available transmission opportunity 911, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the starting symbol of the available transmission opportunity 924.

[0283] Similarly, in Fig. 9 In (a), the second reference time domain interval corresponding to the unlicensed scheduling resource 530 has N=3 available transmission units after the available transmission opportunity 911. The starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the end symbol of the available transmission opportunity 911, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the starting symbol of the available repeated transmission opportunity 934.

[0284] exist Fig. 9In (b), the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the last symbol of the time slot (i.e., time slot 0) where the end symbol of the available transmission opportunity 911 is located, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the first symbol of the time slot (i.e., time slot 9) where the start symbol of the available transmission opportunity 924 is located. Similarly, the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the last symbol of the time slot (i.e., time slot 0) where the end symbol of the available transmission opportunity 911 is located, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the first symbol of the time slot (i.e., time slot 5) where the start symbol of the available repeated transmission opportunity 934 is located.

[0285] exist Fig. 9 In (c), the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the symbol after the end symbol of the available transmission opportunity 911, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 520 is the symbol before the starting symbol of the available transmission opportunity 924. Similarly, the starting position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the symbol after the end symbol of the available transmission opportunity 911, and the ending position of the second reference time domain interval corresponding to the unlicensed scheduling resource 530 is the symbol before the starting symbol of the available repeated transmission opportunity 934.

[0286] A communication method

[0287] In combination with the above content, the following takes the interaction between a terminal device and a network device as an example to introduce an example of a communication method in an embodiment of the present application. It should be noted that the terminal device can be a chip, a chip module or a communication module, etc., and the network device can be a chip, a chip module or a communication module, etc.

[0288] like Fig.10 FIG. 1 is a flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

[0289] S1010. The terminal device obtains at least one transmission unit of each of a plurality of unlicensed scheduling resources, where the transmission unit includes a transmission opportunity and / or a repeated transmission opportunity.

[0290] S1020. The terminal device sends first information on the first transmission unit of the first authorization-free scheduling resource, where the first information is used to indicate the usage status of the transmission unit of the first authorization-free scheduling resource, or the first information is used to indicate the usage status of the transmission unit of the first authorization-free scheduling resource and the transmission unit usage status of other authorization-free scheduling resources among multiple authorization-free scheduling resources except the first authorization-free scheduling resource.

[0291] Correspondingly, the network device receives the first information on the first transmission unit of the first unlicensed scheduling resource.

[0292] It can be seen that the present application realizes reporting of the usage status of the transmission unit under multiple authorization-free scheduling resource configurations through the first information, so that the network equipment can promptly release the transmission units of the authorization-free scheduling resources that will not be used according to the usage status of the transmission unit, thereby improving the system capacity and avoiding resource waste.

[0293] Optionally, the first information includes first usage information corresponding to the first unlicensed scheduling resource, or the first information includes the first usage information and second usage information corresponding to each of the other unlicensed scheduling resources;

[0294] The first usage information is used to indicate the usage status of the available transmission units of the first unlicensed scheduling resource within the first reference time domain interval;

[0295] The second usage information is used to indicate the usage status of the available transmission units of the unlicensed scheduling resource corresponding to the second usage information within the second reference time domain interval;

[0296] The first reference time domain interval and the second reference time domain interval have the same starting position and ending position, or the first reference time domain interval and the second reference time domain interval have the same starting position but different ending positions.

[0297] Optionally, if the first reference time domain interval and the second reference time domain interval have the same starting position and ending position, then

[0298] The available transmission units of the grant-free scheduling resources corresponding to the second usage information within the second reference time domain interval include:

[0299] The available transmission unit of the grant-free scheduling resource corresponding to the second usage information of the starting symbol or the time slot where the starting symbol is located within the first reference time domain interval; and / or,

[0300] The transmission unit of the unlicensed scheduling resource corresponding to the second usage information where the end symbol or the time slot where the end symbol is located is within the first reference time domain interval.

[0301] Optionally, if the first reference time domain interval and the second reference time domain interval have the same starting position but different ending positions, then

[0302] The number of available transmission units of the grant-free scheduling resource corresponding to the second usage information in the second reference time domain interval is equal to the number of transmission units of the first grant-free scheduling resource in the first reference time domain interval.

[0303] Optionally, the first usage information and the second usage information corresponding to each authorization-free scheduling resource in the other authorization-free scheduling resources are sequentially sorted in the first information according to the order of the authorization-free scheduling resource indexes.

[0304] Optionally, the first usage information is arranged in the first information before the second usage information corresponding to each of the other unlicensed scheduling resources;

[0305] The second usage information corresponding to each of the other grant-free scheduling resources is sequentially sorted in the first information according to the order of the grant-free scheduling resource indexes.

[0306] Optionally, each of the multiple unlicensed scheduling resources is associated with the same carrier; or,

[0307] Each of the multiple unlicensed scheduling resources is associated with a different carrier.

[0308] Optionally, if each of the multiple unlicensed scheduling resources is associated with a different carrier, then

[0309] The first usage information and the second usage information corresponding to each unlicensed scheduling resource in the other unlicensed scheduling resources are sorted in the first information in sequence first according to the order of the carrier index and then according to the order of the unlicensed scheduling resource index associated with the same carrier index.

[0310] Optionally, if each of the multiple unlicensed scheduling resources is associated with a different carrier, then
