Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to methods and apparatus for information transmission. Background Technology

[0002] In a Licensed-Assisted Access (LAA-LTE) system based on Long Term Evolution (LTE), carriers on the licensed spectrum serve as the primary carriers, while carriers on the unlicensed spectrum serve as secondary carriers to provide services to terminal devices. On the unlicensed spectrum, communication devices follow the "Listen Before Talk" (LBT) principle. This means that before transmitting a signal on an unlicensed spectrum channel, the communication device must first perform channel listening. Only if the channel listening result indicates that the channel is idle can the communication device transmit a signal; if the channel listening result indicates that the channel is busy, the communication device cannot transmit a signal.

[0003] Since communication equipment transmission is opportunistic, data transmission can only occur if LBT (Low Bit Transmission) is successful and cannot occur if LBT fails. Therefore, network devices and terminal devices in the cell served by the network device need to know when the other party starts and stops data transmission in order to achieve correct data communication between the terminal devices and the network devices.

[0004] When New Radio (NR) technology is applied to unlicensed spectrum, it supports multiple subcarrier spacings and high bandwidth transmission. In this case, how to determine the resource location for data transmission to achieve normal data communication between terminal devices and network devices is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a method and apparatus for transmitting information. Network devices and terminal devices can obtain resource information for data transmission according to this method, thereby enabling normal data communication between network devices and terminal devices.

[0006] In a first aspect, a method for transmitting information is provided, the method comprising:

[0007] The network device determines a first time-domain resource that is idle on the channel detection of the first carrier, and the first time-domain resource is the time-domain resource in the first downlink transmission opportunity;

[0008] The network device sends first information to the terminal device through the first time-domain resources on the first carrier, wherein the first information is used to indicate time-domain resource information for determining the first transmission opportunity based on the first subcarrier interval.

[0009] Therefore, the network device can send first information to the terminal device through the time domain resources in the first downlink transmission opportunity. The first information indicates the method of determining the time domain resource information of the first transmission opportunity (e.g., it may include uplink transmission opportunities and / or downlink transmission opportunities). Thus, the terminal device and the network device reach a consensus on the time domain resource location of the downlink transmission opportunity and / or uplink transmission opportunity, and can realize correct data communication between the terminal device and the network device.

[0010] In some possible implementations, the time-domain resource information includes at least one of the following: start position, end position, time-domain length occupied by the channel, and time slot structure.

[0011] In some possible implementations, the first transmission opportunity includes the first downlink transmission opportunity on the first carrier and / or the first uplink transmission opportunity on the first carrier, wherein the frequency domain resources where the first uplink transmission opportunity is located and the frequency domain resources where the first downlink transmission opportunity is located at least partially overlap.

[0012] Optionally, the frequency domain resources where the first uplink transmission opportunity is located and the frequency domain resources where the first downlink transmission opportunity is located are the same frequency domain resources.

[0013] In some possible implementations, the first information is further used to indicate time-domain resource information for determining a second transmission opportunity based on the first subcarrier spacing, wherein the second transmission opportunity includes at least one of the following: a second downlink transmission opportunity on the first carrier; a second uplink transmission opportunity on the first carrier; a third downlink transmission opportunity on the second carrier; and a third uplink transmission opportunity on the second carrier.

[0014] The frequency domain resources where the second transmission opportunity is located do not overlap with the frequency domain resources where the first transmission opportunity is located.

[0015] Optionally, the first transmission opportunity and the second transmission opportunity may be located on different sub-bands of the same carrier. That is, the first information may be used to indicate time-domain resource information for determining transmission opportunities on at least two sub-bands of the first carrier based on the same sub-carrier spacing.

[0016] Optionally, the first transmission opportunity and the second transmission opportunity may be located on different carriers, that is, the first information may be used to indicate time-domain resource information for determining transmission opportunities on at least two carriers based on the same subcarrier spacing.

[0017] In some possible implementations, the first information is used to indicate the determination of a first end position of the first transmission opportunity based on the first subcarrier interval, and the first information is also used to indicate the determination of a second end position of the second transmission opportunity based on the first subcarrier interval, wherein the distance between the first end position and the second end position is less than or equal to a first preset value.

[0018] In some possible implementations, the first preset value is 1ms.

[0019] In some possible implementations, the first information is further used to indicate time-domain resource information for determining a third transmission opportunity based on the second subcarrier spacing, wherein the third transmission opportunity includes at least one of the following: a fourth downlink transmission opportunity on the first carrier; a fourth uplink transmission opportunity on the first carrier; a fifth downlink transmission opportunity on the second carrier; and a fifth uplink transmission opportunity on the second carrier.

[0020] The frequency domain resources where the third transmission opportunity is located do not overlap with the frequency domain resources where the first transmission opportunity is located.

[0021] Optionally, the first transmission opportunity and the third transmission opportunity may be located on different sub-bands of the same carrier, wherein the time-domain resource locations of the transmission opportunities on different sub-bands may be different. That is, the first information may be used to indicate the time-domain resource information of the transmission opportunities on at least two sub-bands of the first carrier determined according to different sub-carrier intervals.

[0022] Optionally, the first transmission opportunity and the third transmission opportunity may be located on different carriers, wherein the time-domain resource locations of the transmission opportunities on different carriers may be different. That is, the first information may be used to indicate the time-domain resource information of the transmission opportunities on different carriers determined according to different subcarrier intervals.

[0023] By indicating that the time-domain resource locations of transmission opportunities on different sub-bands of the same carrier are different, or that the time-domain resource locations of transmission opportunities on different carriers are different, network devices can release idle frequency domain resources when the load on network devices decreases, which is beneficial to improving the utilization rate of frequency domain resources.

[0024] In some possible implementations, the first information is used to indicate the first end position of the first transmission opportunity determined according to the first subcarrier interval, and the first information is also used to indicate the third end position of the third transmission opportunity determined according to the second subcarrier interval, wherein the distance between the first end position and the third end position is less than or equal to a second preset value.

[0025] In some possible implementations, the second preset value is 1ms.

[0026] In some possible implementations, the method further includes:

[0027] The network device transmits downlink physical channels according to the third subcarrier interval.

[0028] In some possible implementations, the network device sends first information to the terminal device via the first time-domain resources on the first carrier, including:

[0029] The network device sends first information to the terminal device through the first time-domain resources on the first carrier according to the first subcarrier interval.

[0031] The network device sends first information to the terminal device through the first time-domain resources on the first carrier according to the fourth subcarrier interval.

[0032] That is, the subcarrier spacing used to transmit the first information and the subcarrier spacing used to determine the downlink transmission opportunity can be the same or different.

[0033] In general, the first information transmitted on the first carrier can be used to indicate the method for determining the time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities on the first carrier, and can also be used to indicate the method for determining the time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities in at least two sub-bands on the first carrier. The time-domain resource information of the at least two sub-bands can be determined based on the same sub-carrier spacing or based on different sub-carrier spacings. Alternatively, the first information can also be used to indicate the method for determining the time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities on other carriers, such as the second carrier. The time-domain resource information of transmission opportunities on the second carrier and the first carrier can be determined based on the same sub-carrier spacing or based on different sub-carrier spacings. This application embodiment does not limit this.

[0073] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0074] As used in this specification, the terms "component," "module," "system," etc., are used to refer to computer-related entities, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, an execution thread, a program, and / or a computer. As illustrated, applications running on computing devices and computing devices can both be components. One or more components may reside in a process and / or an execution thread, and components may be located on a single computer and / or distributed among two or more computers. Furthermore, these components can be executed from various computer-readable media on which various data structures are stored. Components can communicate, for example, via local and / or remote processes based on signals having one or more data packets (e.g., data from two components interacting with another component between a local system, a distributed system, and / or a network, such as the Internet interacting with other systems via signals).

[0075] The embodiments of this application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, LTE-based access to unlicensed spectrum (LTE-U) system, New Radio (NR) system and evolution systems of NR system, such as NR-based access to unlicensed spectrum (NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi) or next-generation communication systems, etc.

[0076] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication, but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and vehicle-to-vehicle (V2V) communication.

[0077] The communication system in this application embodiment can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, and standalone (SA) network deployment scenarios.

[0078] This application describes various embodiments in conjunction with network devices and terminal devices, wherein:

[0079] Terminal equipment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. Terminal equipment can be a station (STAION, ST) in a WLAN, a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle equipment, wearable device, and next-generation communication systems, such as terminal equipment in fifth-generation (5G) networks or terminal equipment in future evolved Public Land Mobile Network (PLMN) networks.

[0080] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0081] Network devices can be devices used to communicate with mobile devices. Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved base stations (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices in future 5G networks or future evolved PLMN networks, etc.

[0082] In this embodiment, the network device provides services to the cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0083] In the embodiments of this application, multiple cells can operate simultaneously on the same frequency on a carrier in an LTE or 5G system. In certain special scenarios, the concepts of carrier and cell can be considered equivalent. For example, in a carrier aggregation (CA) scenario, when configuring a secondary carrier for a UE, the carrier index of the secondary carrier and the cell identifier (Cell Identify, Cell ID) of the secondary cell operating on that secondary carrier are carried simultaneously. In this case, the concepts of carrier and cell can be considered equivalent; for example, a UE accessing a carrier is equivalent to accessing a cell.

[0084] It should be noted that the downlink physical channels in the embodiments of this application may include a Physical Downlink Control Channel (PDCCH), an Enhanced Physical Downlink Control Channel (EPDCCH), a Physical Downlink Shared Channel (PDSCH), a Physical Hybrid ARQ Indicator Channel (PHICH), a Physical Multicast Channel (PMCH), a Physical Broadcast Channel (PBCH), and so on. Downlink reference signals may include downlink synchronization signals, phase tracking reference signals (PT-RS), downlink demodulation reference signals (DMRS), and channel state information-reference signals (CSI-RS), etc. The downlink synchronization signal can be used for measurement of communication equipment accessing the network and radio resource management; the downlink DMRS can be used for demodulation of the downlink channel; the CSI-RS can be used for measurement of the downlink channel; and the PT-RS can be used for downlink time-frequency synchronization or phase tracking. It should be understood that embodiments of this application may include downlink physical channels or downlink reference signals with the same names but different functions as described above, or they may include downlink physical channels or downlink reference signals with different names but the same functions as described above; this application is not limited in this respect.

[0085] It should be noted that the uplink physical channel in this application embodiment may include a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), and a Physical Uplink Shared Channel (PUSCH), etc. The uplink reference signal may include an uplink demodulation reference signal (DMRS), a sounding reference signal (SRS), and a phase tracking reference signal (PT-RS), etc. Among these, the uplink DMRS can be used for uplink channel demodulation, the SRS can be used for uplink channel measurement, and the PT-RS can be used for uplink time-frequency synchronization or phase tracking. It should be understood that the embodiments in this application may include uplink physical channels or uplink reference signals with the same names but different functions as described above, or they may include uplink physical channels or uplink reference signals with different names but the same functions as described above; this application is not limited in this respect.

[0086] Figure 1 This is a schematic diagram of a communication system according to an embodiment of this application. Figure 1 As shown, the communication system 100 includes network equipment 110 and terminal equipment 120.

[0087] The network device 110 can be any implementation of the aforementioned network device, and the terminal device 120 can be any implementation of the aforementioned terminal device, which will not be elaborated here.

[0088] It should be understood that the communication system 100 can be a PLMN network, a D2D network, an M2M network, or other networks. Figure 1 This is just a simplified illustration; the network may also include other network devices. Figure 1 It was not drawn in the middle.

[0089] In this embodiment, the frequency domain resources used by network devices and terminal devices for wireless communication (e.g., uplink or downlink transmission) are frequency domain resources used based on a contention mechanism.

[0090] For example, network devices and / or terminal devices can detect whether a frequency domain resource with a certain bandwidth (e.g., 20MHz) is currently idle, or whether that frequency domain resource is being used by other devices. If the frequency domain resource is idle, or is not being used by other devices, the network devices and / or terminal devices can use that frequency domain resource for communication, such as uplink or downlink transmission. If the frequency domain resource is not idle, or is being used by other devices, the network devices and / or terminal devices cannot use that frequency domain resource.

[0091] By way of example and not limitation, in this embodiment of the application, the frequency domain resources used by the communication system 100 (or, in other words, the frequency domain resources used by network devices and terminal devices based on a contention mechanism) can also be licensed spectrum resources. That is, the communication system 100 in this embodiment of the application is a communication system capable of using licensed frequency bands, and each communication device (network device and / or terminal device) within the communication system 100 can use the frequency domain resources of the licensed frequency bands in a contention manner. "Licensed frequency domain resources" can also be called "licensed spectrum resources" or "licensed carriers," which refer to frequency domain resources that require approval from a national or local radio commission before they can be used.

[0092] Alternatively, in this embodiment of the application, the frequency domain resources used by the communication system 100 (or, in other words, the frequency domain resources used by network devices and terminal devices based on a contention mechanism) may be unlicensed frequency domain resources. "Unlicensed frequency domain resources" may also be called "unlicensed spectrum resources" or "unlicensed carriers," which refers to resources on unlicensed frequency bands that can be shared by various communication devices.

[0093] By way of example and not limitation, in this application embodiment, the unlicensed spectrum resources may include frequency bands around 5 gigahertz (GHz), frequency bands around 2.4 GHz, frequency bands around 3.5 GHz, frequency bands around 37 GHz, and frequency bands around 60 GHz.

[0094] The following is combined with Figures 2 to 4 The method for transmitting information according to the embodiments of this application will be described. It should be noted that the embodiments of this application mainly involve the determination method of resources in the time domain. The determination method of resources in the frequency domain may be the same as or similar to the prior art. Here, in order to avoid redundancy, its detailed description is omitted.

[0095] It should be understood that Figures 2 to 4 This is a schematic flowchart illustrating a method for transmitting information according to an embodiment of this application. It shows the detailed communication steps or operations of the method, but these steps or operations are merely examples. Other operations may also be performed in this embodiment of the application. Figures 2 to 4 Variations of various operations within it.

[0096] also, Figures 2 to 4 Each step in the process can be followed separately according to... Figures 2 to 4 The different orders presented may be executed, and it is possible that they are not intended to be executed. Figures 2 to 4 All operations within.

[0097] Figure 2 This is a schematic flowchart illustrating a method for transmitting information according to an embodiment of this application, such as... Figure 2 As shown, method 200 includes the following:

[0098] S210, the network device determines a first time-domain resource that is idle on the channel detection of the first carrier, and the first time-domain resource is the time-domain resource in the first downlink transmission opportunity;

[0099] S220, the network device sends first information to the terminal device through the first time domain resources on the first carrier, wherein the first information is used to indicate time domain resource information for determining the first transmission opportunity based on the first subcarrier interval.

[0100] Therefore, the network device can send first information to the terminal device through the time-domain resources in the first transmission opportunity on the first carrier. The first information indicates the method of determining the time-domain resource information of the first transmission opportunity (e.g., it may include uplink transmission opportunities and / or downlink transmission opportunities). Thus, the terminal device and the network device reach a consensus on the time-domain resource location of the first transmission opportunity, and can realize correct data communication between the terminal device and the network device.

[0101] It should be noted that, in the embodiments of this application, the first carrier is an unlicensed carrier, that is, the first information can be used to indicate the determination method of time-domain resource information of transmission opportunities on the unlicensed carrier.

[0102] Optionally, in this embodiment of the application, the first time-domain resource used to send the first information may be a time-domain resource configured by the network device in the first downlink transmission opportunity for transmitting the downlink control channel, such as a time-domain resource in the Control Resource Set (CORESET).

[0103] It should be understood that, in the embodiments of this application, a downlink transmission opportunity can be defined as a time unit of continuous transmission by a network device; similarly, an uplink transmission opportunity can be defined as a time unit of continuous transmission by a terminal device. A time unit can be defined as one or more subframes, one or more time slots, one or more micro-time slots or symbols, etc. The start time unit and / or end time unit of a downlink transmission opportunity or an uplink transmission opportunity can be a complete time unit or a partial time unit, etc., and the embodiments of this application do not limit this.

[0104] Optionally, in the embodiments of this application, the time-domain resource information may include at least one of the following: start position, end position, time-domain length occupied by the channel, and time slot structure. Alternatively, the time-domain resource information may also be other information that can reflect the location of time-domain resources. The embodiments of this application do not impose any particular limitation on this.

[0105] For example, the time-domain resource information of the first transmission opportunity may include the starting position of the first transmission opportunity, such as the starting symbol or the starting timeslot.

[0106] Alternatively, the time-domain resource information of the first transmission opportunity may include the end position of the first transmission opportunity, such as an end symbol or an end slot.

[0107] Alternatively, the time-domain resource information of the first transmission opportunity may include the channel occupancy time of the first transmission opportunity, that is, the time occupied by channel transmission on the first transmission opportunity, such as the number of subframes or the number of time slots.

[0108] Alternatively, the time-domain resource information of the first transmission opportunity may include the time slot structure of the first transmission opportunity. For example, the time slot structure of the first transmission opportunity may be indicated by a bitmap to indicate the time slot structure in one or more time slots, or the time slot structure of the first transmission opportunity may also indicate the number of downlink symbols and / or the number of uplink symbols included in a time slot, or the time slot structure of the first transmission opportunity may indicate the time slot structure index in a time slot. The time slot structure index can be used to indicate a specific time slot structure. The embodiments of this application do not particularly limit the indication method of the time slot structure of the first transmission opportunity.

[0109] Optionally, in this embodiment, the first transmission opportunity may include the first downlink transmission opportunity and / or the first uplink transmission opportunity on the first carrier. That is, the network device can not only indicate the time-domain resource information of the downlink transmission opportunity on the first carrier through the first information, but also indicate the time-domain resource information of the uplink transmission opportunity on the first carrier through the first information. In this way, the terminal device and the network device can reach a consensus on the time-domain resource location of the downlink transmission opportunity and / or the uplink transmission opportunity on the first carrier, thereby enabling correct data communication between the terminal device and the network device.

[0110] Optionally, in some embodiments, the frequency domain resources where the first uplink transmission opportunity is located on the first carrier and the frequency domain resources where the first downlink transmission opportunity is located on the first carrier overlap at least partially. For example, the first downlink transmission opportunity and the first uplink transmission opportunity on the first carrier may be located on the same sub-band on the first carrier.

[0111] It should be understood that, in the embodiments of this application, the first subcarrier spacing used to determine the time-domain resource information of the first transmission opportunity may be a subcarrier spacing defined by the communication system, or the first subcarrier spacing may be a subcarrier spacing configured by the network device, or the first subcarrier spacing may be a subcarrier spacing used by the network device to transmit downlink control information, etc., and the embodiments of this application do not limit it in this way.

[0112] Optionally, the size of the first subcarrier spacing is less than or equal to the size of the subcarrier spacing used for physical channel transmission on the first carrier.

[0113] The following details the method of indicating this first information.

[0114] Example 1: The first information can also be used to indicate time-domain resource information for determining a second transmission opportunity based on the first subcarrier spacing, wherein the second transmission opportunity includes at least one of the following:

[0115] The second downlink transmission opportunity on the first carrier;

[0116] The second uplink transmission opportunity on the first carrier;

[0117] The third downlink transmission opportunity on the second carrier;

[0118] The third uplink transmission opportunity on the second carrier;

[0119] The frequency domain resources where the second transmission opportunity is located do not overlap with the frequency domain resources where the first transmission opportunity is located.

[0120] In other words, the first information can not only indicate the time-domain resource information for determining the first transmission opportunity based on the first subcarrier interval, but also be used to indicate the time-domain resource information for determining the second transmission opportunity based on the first subcarrier interval. That is, the network device can indicate the time-domain resource information for determining the first and second transmission opportunities based on the same subcarrier interval. Depending on the frequency domain location of the first and second transmission opportunities, the following two scenarios can be included.

[0121] Scenario 1: The first transmission opportunity and the second transmission opportunity may be located on different sub-bands of the same carrier. For example, the first carrier may include a first sub-band and a second sub-band. The first transmission opportunity may be located on the first sub-band of the first carrier, and the second transmission opportunity may be located on the second sub-band of the first carrier. Specifically, the first transmission opportunity may include a first uplink transmission opportunity and / or a first downlink transmission opportunity on the first sub-band of the first carrier, and the second transmission opportunity may include a second uplink transmission opportunity and / or a second downlink transmission opportunity on the second sub-band of the first carrier.

[0122] Scenario 2: The first transmission opportunity and the second transmission opportunity may be located on different carriers. For example, the first transmission opportunity may be located on the first carrier, and the second transmission opportunity may be located on the second carrier. The first transmission opportunity may include a first uplink transmission opportunity and / or a first downlink transmission opportunity on the first carrier, and the second transmission opportunity may include a third downlink transmission opportunity and / or a third uplink transmission opportunity on the second carrier. Optionally, the third downlink transmission opportunity and the third uplink transmission opportunity on the second carrier may be located on the same sub-band of the second carrier.

[0123] Based on this embodiment 1, the first information transmitted on the first carrier can be used to indicate time-domain resource information for determining transmission opportunities on at least two sub-bands of the first carrier according to the same sub-carrier spacing, i.e., scenario 1. In this case, the time-domain resource locations of the transmission opportunities on the at least two sub-bands can be the same, and the first information can indicate only one type of time-domain resource information. Alternatively, the time-domain resource locations of the transmission opportunities on the at least two sub-bands can be different, and the first information can be used to indicate the time-domain resource location of the transmission opportunities on each of the at least two sub-bands.

[0124] Alternatively, the first information transmitted on the first carrier can be used not only to indicate the method of determining the time-domain resource information of the first transmission opportunity on the first carrier, but also to indicate the method of determining the time-domain resource information of the second transmission opportunity on other carriers, such as the second carrier. That is, the first information can be used to indicate the method of determining the time-domain resources of the transmission opportunities on at least two carriers. The subcarrier spacing on which the time-domain resource information used to determine the first transmission opportunity on the first carrier and the time-domain resource information used to determine the second transmission opportunity on the second carrier are based can be the same, i.e., scenario 2.

[0125] Optionally, in this embodiment of the application, the second carrier may be an unlicensed carrier that is different from the first carrier.

[0126] In a specific embodiment of Example 1, the first information is used to indicate the first end position of the first transmission opportunity determined according to the first subcarrier interval, and the first information is also used to indicate the second end position of the second transmission opportunity determined according to the first subcarrier interval, wherein the distance between the first end position and the second end position is less than or equal to a first preset value.

[0127] Optionally, in some embodiments, the first preset value can be 1ms.

[0128] For example, in scenario 1, the end positions of transmission opportunities on at least two sub-bands of the first carrier may be different. In this case, the time interval between the end positions of transmission opportunities on at least two sub-bands is not greater than the first preset value.

[0129] Alternatively, in scenario 2, the end positions of the transmission opportunities on the first carrier and the second carrier may be different. In this case, the time interval between the end positions of the transmission opportunities on the first carrier and the second carrier is not greater than the first preset value.

[0130] Example 2: The first information can also be used to indicate time-domain resource information for determining a third transmission opportunity based on the second subcarrier spacing, wherein the third transmission opportunity includes at least one of the following:

[0131] The fourth downlink transmission opportunity on the first carrier;

[0132] The fourth uplink transmission opportunity on the first carrier;

[0133] The fifth downlink transmission opportunity on the second carrier;

[0134] The fifth uplink transmission opportunity on the second carrier;

[0135] The frequency domain resources where the third transmission opportunity is located do not overlap with the frequency domain resources where the first transmission opportunity is located.

[0136] In other words, the first information can be used not only to indicate the time-domain resource information for determining the first transmission opportunity based on the first subcarrier interval, but also to indicate the time-domain resource information for determining the third transmission opportunity based on a non-first subcarrier interval, such as the second subcarrier interval. Based on the frequency domain positions of the first and third transmission opportunities, the following two scenarios can be distinguished.

[0137] Scenario 3: The first transmission opportunity and the third transmission opportunity may be located on different sub-bands of the same carrier. For example, the first carrier may include a first sub-band and a second sub-band. The first transmission opportunity may be located on the first sub-band of the first carrier, and the third transmission opportunity may be located on the second sub-band of the first carrier. That is, the first information can be used to indicate time-domain resource information for determining transmission opportunities on different sub-bands of the first carrier based on different sub-carrier spacing. For example, the first transmission opportunity may include a first uplink transmission opportunity and / or a first downlink transmission opportunity on the first sub-band of the first carrier, and the third transmission opportunity may include a fourth uplink transmission opportunity and / or a fourth downlink transmission opportunity on the second sub-band of the first carrier.

[0138] Scenario 4: The first transmission opportunity and the third transmission opportunity may be located on different carriers. For example, the first transmission opportunity may be located on the first carrier, and the third transmission opportunity may be located on the second carrier. The first transmission opportunity may include a first uplink transmission opportunity and / or a first downlink transmission opportunity on the first carrier, and the third transmission opportunity may include a fifth downlink transmission opportunity and / or a fifth uplink transmission opportunity on the second carrier. Optionally, the fifth downlink transmission opportunity and the fifth uplink transmission opportunity on the second carrier may be located on the same sub-band of the second carrier.

[0139] Based on this embodiment 2, the first information transmitted on the first carrier can be used to indicate the time-domain resource information of the transmission opportunities on different sub-bands of the first carrier according to different sub-carrier intervals, i.e., scenario 3. In this scenario, the time-domain resource positions of the transmission opportunities on different sub-bands can be different. For example, the network device can have different ending positions of downlink transmission opportunities on different sub-bands. Thus, when the load on the network device decreases, the network device can release idle frequency domain resources, which is beneficial to improving the utilization rate of frequency domain resources.

[0140] Alternatively, the first information transmitted on the first carrier can be used to indicate the time-domain resource information for determining transmission opportunities on different carriers based on different subcarrier intervals, i.e., scenario 4. In this scenario, the time-domain resource positions of the transmission opportunities on different carriers can also be different. For example, the network device can have different end positions of downlink transmission opportunities on different carriers, so that when the load on the network device decreases, the network device can release idle frequency domain resources, thereby improving the utilization rate of frequency domain resources.

[0141] Optionally, in a specific embodiment of this embodiment 2, the first information is used to indicate the first end position of the first transmission opportunity determined according to the first subcarrier interval, and the first information is also used to indicate the third end position of the third transmission opportunity determined according to the second subcarrier interval, wherein the distance between the first end position and the third end position is less than or equal to a second preset value.

[0142] For example, in scenario 3, the first end position of the first transmission opportunity can be the first end position of the transmission opportunity on the first sub-band of the first carrier, and the third end position of the third transmission opportunity can be the third end position of the transmission opportunity on the second sub-band of the first carrier; or, in scenario 4, the first end position of the first transmission opportunity can be the first end position of the transmission opportunity on the first carrier, and the third end position of the third transmission opportunity can be the third end position of the transmission opportunity on the second carrier. The first end position and the third end position can be different. In this case, the time interval between the first end position and the third end position is not greater than a second preset value.

[0143] Optionally, in some embodiments, the second preset value can be 1ms.

[0144] Combining Embodiments 1 and 2, the first information transmitted on the first carrier can be used to indicate the determination method of time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities on the first carrier, and can also be used to indicate the determination method of time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities in at least two sub-bands on the first carrier. The time-domain resource information of the at least two sub-bands can be determined based on the same subcarrier spacing, or it can be determined based on different subcarrier spacings. Alternatively, the first information can also be used to indicate the determination method of time-domain resource information of downlink transmission opportunities and / or uplink transmission opportunities on other carriers, such as the second carrier. The time-domain resource information of transmission opportunities on the second carrier and the first carrier can be determined based on the same subcarrier spacing, or it can be determined based on different subcarrier spacings. This application does not limit this aspect.

[0145] Optionally, in some embodiments, the method 200 may further include:

[0146] The network device transmits downlink physical channels based on the third subcarrier interval.

[0147] The third subcarrier interval and the first subcarrier interval can be different. That is, the subcarrier interval used to transmit the downlink physical channel and the subcarrier interval used to determine the downlink transmission opportunity can be different. In other words, after determining the time-domain resource information on the downlink transmission opportunity based on the first subcarrier interval, the downlink physical channel can be transmitted based on the third subcarrier interval, which is different from the first subcarrier interval, when actually transmitting data. Of course, the network device can also transmit the downlink physical channel based on the first subcarrier interval. This application embodiment does not specifically limit this.

[0148] For example, such as Figure 3 As shown, taking a first subcarrier spacing of 15kHz as an example, the network device can determine the time-domain resource information of the first downlink transmission opportunity based on 15kHz, such as the time-domain length or end position of the channel occupied on the first downlink transmission opportunity. When actually transmitting data on the time-domain resources corresponding to the first downlink transmission opportunity, the network device can transmit the downlink physical channel according to the same or different subcarrier spacing as the first subcarrier spacing (for example, it can be based on one or more subcarrier spacings of 15kHz, 30kHz and 60kHz) after successful channel detection (e.g., successful LBT, or successful Clear Channel Assessment (CCA)).

[0149] For example, such as Figure 4As shown, the first carrier may include sub-band #1 and sub-band #2. The first information can be used to indicate the time-domain resource information of the first downlink transmission opportunity corresponding to sub-band #1 determined according to the first sub-carrier interval (e.g., 15kHz), and can also be used to indicate the time-domain resource information of the second downlink transmission opportunity corresponding to sub-band #2 determined according to the second sub-carrier interval (e.g., 30kHz). The end positions of the downlink transmission opportunities on sub-band #1 and sub-band #2 may be different. Optionally, the time difference between the end positions may be less than or equal to a second preset value.

[0150] When data transmission actually occurs in sub-band #1 and sub-band #2, the network device can transmit a downlink physical channel in sub-band #1 according to a sub-carrier spacing that is the same as or different from the first sub-carrier spacing (e.g., in the time domain resources of the first downlink transmission opportunity in sub-band #1, a downlink physical channel can be transmitted according to one or more sub-carrier spacings of 15kHz, 30kHz, and 60kHz). It can also transmit a downlink physical channel in sub-band #2 according to a sub-carrier spacing that is the same as or different from the second sub-carrier spacing (e.g., in the time domain resources of the second downlink transmission opportunity in sub-band #2, a downlink physical channel can also be transmitted according to one or more sub-carrier spacings of 15kHz, 30kHz, and 60kHz).

[0151] Optionally, in some embodiments, S220 may specifically include:

[0152] The network device sends first information to the terminal device via the first time-domain resources on the first carrier according to the first subcarrier interval; or...

[0153] The network device sends the first information to the terminal device through the first time-domain resources on the first carrier according to the fourth subcarrier interval.

[0154] The first subcarrier interval and the fourth subcarrier interval are different. That is, the subcarrier interval used to transmit the first information and the subcarrier interval used to determine the downlink transmission opportunity can be the same or different. Specifically, the network device can determine the downlink control resources used to transmit the first information. The downlink control resources can be determined based on the first subcarrier interval or other subcarrier intervals. This application embodiment does not limit this. The downlink control resources are the aforementioned first time-domain resources. Further, the network device can transmit the first information on the downlink control resources on the first carrier according to the first subcarrier interval or a non-first subcarrier interval, such as the fourth subcarrier interval.

[0155] Therefore, in the method for transmitting information according to the embodiments of this application, the network device can indicate the method for determining the time-domain resource location of transmission opportunities on unlicensed carriers through indication information. Optionally, if the unlicensed carrier includes at least two sub-frequency bands, the indication information can also be used to indicate the time-domain resource information for determining the transmission opportunities on the at least two sub-frequency bands based on the same reference sub-carrier spacing (i.e., the first sub-carrier spacing), or to determine the time-domain resource information for determining the transmission opportunities on each sub-frequency band based on an independent reference sub-carrier spacing; or, the first information can also be used to indicate the time-domain resource information for determining the transmission opportunities on at least two carriers based on the same reference sub-carrier spacing, or to indicate the time-domain resource information for determining the transmission opportunities on each carrier based on an independent reference sub-carrier spacing. Thus, the terminal device and the network device can reach a consensus on the time-domain resource location of uplink transmission opportunities and / or downlink transmission opportunities, enabling normal data communication between the network device and the terminal device.

Correspondingly, terminal devices can also perform the signal transmission method according to the embodiments of the present application in a similar manner.

Optionally, if the unlicensed carrier includes at least two sub-bands, the indication information can also be used to indicate the time-domain resource information for determining the transmission opportunities on the at least two sub-bands based on the same reference sub-carrier spacing (i.e., the first sub-carrier spacing), or to determine the time-domain resource information for determining the transmission opportunities on each sub-band based on an independent reference sub-carrier spacing; or, the first information can also be used to indicate the time-domain resource information for determining the transmission opportunities on at least two carriers based on the same reference sub-carrier spacing, or it can also be used to indicate the time-domain resource information for determining the transmission opportunities on each carrier based on an independent reference sub-carrier spacing.

[0188] Therefore, in the method for transmitting information according to the embodiments of this application, the network device can indicate the method for determining the time-domain resource location of transmission opportunities on unlicensed carriers through indication information. Optionally, if the unlicensed carrier includes at least two sub-frequency bands, the indication information can also be used to indicate the time-domain resource information for determining the transmission opportunities on the at least two sub-frequency bands based on the same reference sub-carrier spacing (i.e., the first sub-carrier spacing), or to determine the time-domain resource information for determining the transmission opportunities on each sub-frequency band based on an independent reference sub-carrier spacing; or, the first information can also be used to indicate the time-domain resource information for determining the transmission opportunities on at least two carriers based on the same reference sub-carrier spacing, or to indicate the time-domain resource information for determining the transmission opportunities on each carrier based on an independent reference sub-carrier spacing.
