Description

[Technical field]

[0001] The present application relates to the field of communications, and in particular to a method for configuring transmission resource cancellation indication information, a terminal device, and a network device. [Background technology]

[0002] The New Radio (NR) system introduces two services: Ultra-reliable low latency (URLLC) and Enhanced Mobile Broadband (eMBB). URLLC has the characteristic of realizing ultra-reliable (e.g. 99.999%) transmission with very short latency (e.g. 1ms), while eMBB has the characteristic of supporting a large number of transmissions while not being sensitive to latency. In a scenario where URLLC and eMBB coexist, when URLLC instantaneous transmission is implemented, if URLLC and eMBB transmissions conflict, URLLC and eMBB may interfere with each other, affecting the demodulation function of URLLC. Retransmission can mitigate this effect, but the transmission delay of URLLC increases.

[0003] One of the current solutions to the problem of contention of uplink transmission between URLLC and eMBB is to stop eMBB transmission to reduce interference to URLLC. In the case of multi-carrier, when signal transmission on a certain carrier is interrupted, transmission on another carrier at the same position in the time domain must also be interrupted. For example, when component carrier 1 (CC1) and CC2 are transmitted simultaneously, if the subcarrier spacing of CC1 and CC2 is the same, the signal interruption state is as shown in case 1 of Figure 1, and if the subcarrier spacing of CC1 is 15kHZ and the subcarrier spacing of CC2 is 30kHZ, the time length of each symbol of CC1 is twice the time length of each symbol of CC2, and the signal interruption state is as shown in case 2 and case 3 of Figure 1.

[0004] The network side can notify the eMBB user of the resource occupancy state of the URLLC service through the transmission resource cancellation indication information, so that the eMBB user can stop eMBB transmission to reduce interference with the URLLC. Therefore, how to configure the transmission resource cancellation indication information to simplify the signal interruption processing process and improve the efficiency of the communication system is currently a problem to be solved.

[0018] The following describes the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application, and obviously, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

[0020] Exemplarily, a communication system 100 to which the present embodiment is applied is as shown in Fig. 2. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, referred to as a terminal). The network device 110 may provide communication coverage in a specific geographic area and may communicate with the terminal device located within the coverage area. For example, the network device 110 may be a base station (Base Transceiver Station, BTS) of a GSM system or a CDMA system, or a base station (Node B, NB) of a WCDMA system, or an evolved base station (Evolutional Node B, eNB or eNodeB) of an LTE system, or a radio controller in a Cloud Radio Access Network (CRAN), or the network device may be a mobile switching center, a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a network bridge, a router, a network side device of a 5G network, or a network device of a Public Land Mobile Network (PLMN) that will evolve in the future, etc.

[0021] The communication system 100 further includes at least one terminal device 120 within the coverage of the network device 110. A "terminal device" as used herein may include, but is not limited to, a device configured to transmit and receive communication signals via a wired connection (Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, direct cable connection, etc.), and / or via another data connection / network, and / or via a wireless interface (e.g., a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, etc.), and / or via another communication terminal, and an Internet of Things (IoT) device. A terminal device configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". A mobile terminal may be, for example, a satellite or mobile telephone, a Personal Communications System (PCS) terminal combining cellular radiotelephone with data processing, fax, and data communication capabilities, a wireless telephone, a pager, a PDA including Internet / Intranet access, a Web browser, a memo pad, a calendar, and / or a Global Positioning System (GPS) receiver, or other electronic device including a traditional laptop and / or palmtop receiver or radiotelephone transceiver.

[0022] Exemplarily, device-to-device (D2D) communication can be performed between the terminal devices 120.

[0023] Illustratively, a 5G system or a 5G network may also be referred to as a New Radio (NR) system or a NR network.

[0024] FIG. 2 shows one network device and two terminal devices as an example, and illustratively, the communication system 100 may include multiple network devices, and the coverage of each network device may include other numbers of terminal devices, and the embodiments of the present application are not limited thereto.

[0025] By way of example, the communication system 100 may further include other network entities, such as a network controller, a mobile management entity, etc., but the present embodiment is not limited thereto.

[0026] It should be understood that in the present embodiment, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in Fig. 2 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the above specific devices, and will not be described again here. The communication device may also include other devices in the communication system 100, such as other network entities such as a network controller, a mobile management entity, etc., but the present embodiment is not limited thereto.

[0027] It should be understood that the terms "system" and "network" are always used interchangeably herein. The term "and / or" in this specification is only a relational relationship describing related objects, and indicates that three relations may exist, for example, A and / or B can indicate three cases: A exists independently, A and B both exist, and B exists independently. Furthermore, the symbol " / " in this specification generally indicates that the relationship between related objects is an "or" relationship.

[0028] The NR system has two services: URLLC and eMBB. URLLC has the characteristic of realizing ultra-high reliability (e.g., 99.999%) transmission with very short delay (e.g., 1 ms), while eMBB has the characteristic of supporting a large number of transmissions while not being sensitive to delay. In a scenario where RLLC and eMBB coexist, when implementing URLLC immediate transmission, if URLLC and eMBB transmissions conflict, URLLC and eMBB may interfere with each other, affecting the demodulation function of URLLC. This effect can be mitigated by retransmission, but the transmission delay of URLLC will increase.

[0029] One of the current solutions to the problem of uplink transmission contention between URLLC and eMBB transmission is to stop eMBB transmission to reduce interference to URLLC. The network side can notify the eMBB user of the resource occupancy state of the URLLC service via the transmission resource cancellation indication information, so that the eMBB user can stop eMBB transmission to reduce interference to URLLC.

[0030] In the related art, the reference time region of the transmission resource cancellation indication information (e.g., Uplink Cancellation Indication (UL CI) or Uplink Cancellation Information (UL CI)) can be configured, and the symbol is used as a unit during the configuration. For example, when CC1 and CC2 are transmitted simultaneously, if the subcarrier intervals of CC1 and CC2 are the same, the signal interruption state is as shown in case 1 of FIG. 3. If the subcarrier interval of CC1 is 15 kHz and the subcarrier interval of CC2 is 30 kHz, the time length of each symbol of CC1 is twice the time length of each symbol of CC2. If the configured Reference time region is 2 symbols, the indication result is that some symbols of CC2 cannot be covered by the Reference Time Region, as shown in case 1 of FIG. 3. If the configured Reference time region is 4 symbols, the indication result is that some symbols of CC1 are repeatedly indicated, as shown in case 2 of FIG. 3.

[0031] Based on the related art, how to configure the transmission resource cancellation indication information so as to simplify the signal interruption handling process and improve the efficiency of the communication system is currently a problem to be solved.

[0032] Therefore, an embodiment of the present application proposes a method for configuring a transmission resource cancellation indication information, and the configuration information of the transmission resource cancellation indication information includes at least one of a reference time domain range, a reference frequency domain range, a transmission resource cancellation indication bit number, a time domain indication granularity, and information for determining a start point offset of the transmission resource cancellation indication information. In this way, in the case of multi-carrier, when configuring the transmission resource cancellation indication information for each carrier, a reference time position and a time domain indication granularity of the same time length are used, thereby simplifying the signal interruption processing process in multi-carrier and improving system efficiency.

[0033] 4 is an exemplary flowchart of a method 200 for configuring transmission resource cancellation indication information according to an embodiment of the present application. The method 200 can be performed by a terminal device and a network device, for example, the terminal device can be the terminal device shown in FIG. 2, and the network device can be the network device shown in FIG.

[0034] As shown in Fig. 4, the method 200 includes the following steps: in step 210, sending configuration information, i.e., the network device sends configuration information to the terminal device, where the configuration information is used to configure transmission resource cancellation indication information, and the configuration information includes at least one of a first reference time domain range, a reference frequency domain range, a transmission resource cancellation indication bit number, a first time domain indication granularity, and information for determining a start point offset of the transmission resource cancellation indication information.

[0035] As shown in Fig. 4, the method 200 further includes the following steps: In step 220, receiving configuration information, i.e. the terminal device receives configuration information from a network device, where the configuration information is used to configure a transmission resource cancellation indication information, and the configuration information includes at least one of a first reference time domain range, a reference frequency domain range, a transmission resource cancellation indication bit number, a first time domain indication granularity, and information for determining a start point offset of the transmission resource cancellation indication information.

[0036] It should be understood that after receiving the configuration information from the network equipment, the terminal equipment can analyze the transmission resource cancellation indication information based on the configuration information to obtain the resource location where the transmission is canceled.

[0037] In addition, if the configuration information does not include information for determining the start point offset of the transmission resource cancellation indication information, the terminal device can determine the start point offset of the transmission resource cancellation indication information based on the terminal capabilities.

[0038] Exemplarily, in some embodiments, the starting point of the first Reference Time Region may be defined based on the following scheme.

[0039] In TIFF0007598339000001.tif84170 scheme 2, when the terminal detects the transmission resource cancellation indication information in the PDCCH transmitted in a specific CORESET in a specific slot, the reference time domain range starts from X symbols after the end symbol of the PDCCH CORESET carrying the transmission resource cancellation indication information, where X is configured by the value of the preemption-to-reference time region timing of the serving cell mapped to each field of the transmission resource cancellation indication information.

[0040] Exemplarily, in some embodiments, the time length corresponding to the first reference time region range (Reference Time Region) may be defined based on the following scheme.

[0041] In the first scheme, the reference time region duration is T, where T is configured by the value of the reference time region duration of the serving cell mapped to the respective field of the transmission resource cancellation indication information.

[0042] TIFF0007598339000002.tif59170As an example, the first reference time region range is configured independently for different carriers. Or, it can be understood that the first reference time region range can be configured independently for each carrier. It is assumed that the Reference Time Region needs to be configured for two carriers (CC1 and CC2), the subcarrier interval corresponding to CC1 is 15kHz, the time length corresponding to each symbol is t1, the subcarrier interval corresponding to CC2 is 30kHz, the time length corresponding to each symbol is t2, and t1=t2*2.

[0043] 5, if the time length corresponding to the reference time region to be constructed is T5=2*t1, the time length corresponding to each symbol of CC1 is t1, and two symbols are required to reach T5, so the constructed reference time region is 2 symbols. Also, the time length corresponding to each symbol of CC2 is t2, and four symbols are required to reach T5, so the constructed reference time region is 4 symbols.

[0044] 6, if the time length corresponding to the reference time region to be constructed is T5=7*t1, the time length corresponding to each symbol of CC1 is t1, and 7 symbols are required to reach T5, so the constructed reference time region is 7 symbols. Also, the time length corresponding to each symbol of CC2 is t2, and 14 symbols are required to reach T5, so the constructed reference time region is 14 symbols.

[0045] 7, if the time length corresponding to the reference time region to be constructed is T6=14*t1, the time length corresponding to each symbol of CC1 is t1, and 14 symbols are required to reach T6, so the constructed reference time region is 14 symbols. Also, the time length corresponding to each symbol of CC2 is t2, and 28 symbols are required to reach T6, so the constructed reference time region is 28 symbols.

[0046] As another example, a reference time domain range of each carrier is determined based on a subcarrier interval of the each carrier and the first reference time domain range, and the first reference time domain range corresponds to a first subcarrier interval. The first subcarrier interval is configured by a network device, or the first subcarrier interval is pre-determined according to a protocol. If the first subcarrier interval is configured by a network device, the configuration information further includes the first subcarrier interval.

[0047] For example, as shown in Figure 8, the Reference Time Region needs to be configured in two carriers (CC1 and CC2), the subcarrier interval corresponding to CC1 is 15kHz, the time length corresponding to each symbol is t1, the subcarrier interval corresponding to CC2 is 30kHz, the time length corresponding to each symbol is t2, and t1 = t2 * 2. Assume that the reference subcarrier interval configured by the network or pre-determined by the protocol is 30kHz (the same as the subcarrier interval corresponding to CC2), and the time length corresponding to each symbol is t2. If the time length corresponding to the first Reference Time Region is T7 = 14 * t1, the reference subcarrier interval is 30kHz, the time length corresponding to each symbol is t2, and 28 symbols are required to reach T7, so the Reference Time Region that needs to be configured in CC1 is 28 symbols, and the reference time region that needs to be configured in CC2 is 28 symbols.

[0048] Based on the above embodiments, the first subcarrier spacing is a subcarrier spacing of a carrier carrying the transmission resource cancellation indication information, or the first subcarrier spacing is a minimum subcarrier spacing among subcarrier spacings of a plurality of carriers, or the first subcarrier spacing is a maximum subcarrier spacing among subcarrier spacings of a plurality of carriers, or the first subcarrier spacing is a reference subcarrier spacing used when configuring a Slot Format Indicator (SFI), or the first subcarrier spacing is a minimum subcarrier spacing among subcarrier spacings corresponding to FR1 (Frequency Range 1), or the first subcarrier spacing is a maximum subcarrier spacing among subcarrier spacings corresponding to FR1, or the first subcarrier spacing is a minimum subcarrier spacing among subcarrier spacings corresponding to FR2 (Frequency Range 2), or the first subcarrier spacing is a maximum subcarrier spacing among subcarrier spacings corresponding to FR1, or the first subcarrier spacing is a subcarrier spacing indicated by physical signaling.

[0049] The first subcarrier spacing is a downlink subcarrier spacing, or the first subcarrier spacing is an uplink subcarrier spacing.

[0050] As specific examples, the first reference time domain range values ​​include one of 1 symbol, 2 symbols, 4 symbols, 7 symbols, 14 symbols, 21 symbols, 28 symbols, 35 symbols, and 42 symbols.

[0051] As a specific example, the value of the first reference time domain range is M*2 n symbols, n is a non-negative integer, and M is a positive integer. The relationship between the symbol lengths of different subcarrier spacings is 2 nConsidering that n is the difference in the serial numbers of the subcarrier intervals, in order to configure the same time length in the reference time domain range of carriers using different subcarrier intervals, M*2 n symbols are introduced. Typically, M=1, 2, 4, 7, and n=0, 1, 2. Therefore, the value of the first reference time domain range is 1*2 n , 2*2 n , 4*2 n , and 7*2 n Illustratively, in some embodiments, a time length corresponding to the first reference time domain range is greater than or equal to a period of a search space in which the transmission resource cancellation indication information is located.

[0052] Illustratively, in some embodiments, the time lengths corresponding to the reference time domain ranges of different carriers are the same.

[0053] As another example, the first time domain indication granularity may be configured independently for different carriers. Or, the first time domain indication granularity may be configured independently for each carrier. Exemplarily, a time length corresponding to the first time domain indication granularity is smaller than or equal to a time length corresponding to the first reference time domain range.

[0054] For example, as shown in FIG. 9, it is assumed that it is necessary to configure a time domain indication granularity for two carriers (CC1 and CC2), the subcarrier interval corresponding to CC1 is 15 kHz, the time length corresponding to each symbol is t1, and the subcarrier interval corresponding to CC2 is 30 kHz, the time length corresponding to each symbol is t2, and t1=t2*2. If the time length corresponding to the first time domain indication granularity to be configured is T1=t1, the time length corresponding to each symbol of CC1 is t1, and one symbol is required to reach T1, so the configured first time domain indication granularity is 1 symbol. Also, the time length corresponding to each symbol of CC2 is t2, and two symbols are required to reach T1, so the configured time domain indication granularity is 2 symbols.

[0055] 10, if the time length corresponding to the first time domain indication granularity to be constructed is T2=2*t1, the time length corresponding to each symbol of CC1 is t1 and two symbols are required to reach T2, so the constructed first time domain indication granularity is 2 symbols. Also, the time length corresponding to each symbol of CC2 is t2 and four symbols are required to reach T2, so the constructed time domain indication granularity is 4 symbols.

[0056] As another example, a time domain indication granularity of each carrier is determined based on a subcarrier spacing of the each carrier and the first time domain indication granularity, and the first time domain indication granularity corresponds to a second subcarrier spacing. The second subcarrier spacing is configured by a network device, or the second subcarrier spacing is pre-determined according to a protocol. If the second subcarrier spacing is configured by a network device, the configuration information further includes the second subcarrier spacing.

[0057] Exemplarily, the second subcarrier spacing is the subcarrier spacing of a carrier carrying the transmission resource cancellation indication information, or the second subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacings of a plurality of carriers, or the second subcarrier spacing is the maximum subcarrier spacing among the subcarrier spacings of a plurality of carriers, or the second subcarrier spacing is a reference subcarrier spacing used when configuring an SFI, or the second subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacings corresponding to FR1, or the second subcarrier spacing is the maximum subcarrier spacing among the subcarrier spacings corresponding to FR1, or the second subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacings corresponding to FR2, or the second subcarrier spacing is the maximum subcarrier spacing among the subcarrier spacings corresponding to FR2, or the second subcarrier spacing is a subcarrier spacing indicated by physical signaling.

[0058] In this embodiment, the second subcarrier spacing is a downlink subcarrier spacing, or the second subcarrier spacing is an uplink subcarrier spacing.

[0059] For example, as shown in Figure 11, it is assumed that it is necessary to configure time domain indication granularity for two carriers (CC1 and CC2), the subcarrier interval corresponding to CC1 is 15kHz, the time length corresponding to each symbol is t1, the subcarrier interval corresponding to CC2 is 30kHz, the time length corresponding to each symbol is t2, t1 = t2 * 2, the reference subcarrier interval configured by the network or pre-determined according to the protocol is 30kHz, the time length corresponding to each symbol is t2. If the time length corresponding to the first time domain indication granularity to be configured is T3 = t1, the reference subcarrier interval is 30kHz, the time length corresponding to each symbol is t2, and two symbols are required to reach T3, so the time domain indication granularity to be configured for CC1 is 2symbols, and the time domain indication granularity to be configured for CC2 is 2symbols.

[0060] Suppose that it is necessary to configure a time domain indication granularity for two carriers (CC1 and CC2), the subcarrier spacing corresponding to CC1 is 15 kHz, the time length corresponding to each symbol is t1, the subcarrier spacing corresponding to CC2 is 30 kHz, the time length corresponding to each symbol is t2, and t1=t2*2. The reference subcarrier spacing is the subcarrier spacing of 30 kHz used when transmitting the transmission resource cancellation indication information, and the time length corresponding to each symbol is t2. If the time length corresponding to the first time domain indication granularity to be configured is T3=t1, the reference subcarrier spacing is 30 kHz, the time length corresponding to each symbol is t2, and two symbols are required to reach T3, so the time domain indication granularity to be configured for CC1 is 2 symbols, and the time domain indication granularity to be configured for CC2 is 2 symbols. The downlink subcarrier spacing is used as the reference subcarrier spacing, but the transmission resource cancellation indication information is configured to indicate the uplink transmission resource. By indicating the time domain indication granularity via the reference downlink subcarrier spacing, it is ensured that the indicated time domain resource range coincides with the period of the indication information, thereby avoiding coverage loss or repeated coverage.

[0061] Or, the time lengths corresponding to the time domain indication granularities of different carriers are the same, as shown in Fig. 12. When the time length corresponding to the first time domain indication granularity that needs to be configured is T4=2*t1, the reference subcarrier interval is 30 kHz, the time length corresponding to each symbol is t2, and four symbols are needed to reach T4, so the time domain indication granularity that needs to be configured in CC1 is 4 symbols, and the time domain indication granularity that needs to be configured in CC2 is 4 symbols.

[0062] Exemplarily, as one example, the start point of the first reference time domain range is determined based on the transmission end time of the transmission resource cancellation indication information and the start point offset of the transmission resource cancellation indication information, or it can be understood that the start point offset (X) of the transmission resource cancellation indication information is a time interval from the transmission end time of the transmission resource cancellation indication information to the start point of the first reference time domain range.

[0063] The following describes a method for configuring the start point offset of the transmission resource cancellation indication information with reference to a specific example. It is necessary to configure the time domain indication granularity for two carriers (CC1 and CC2), and it is assumed that the subcarrier interval corresponding to CC1 is 15 kHz, the time length corresponding to each symbol is t1, the subcarrier interval corresponding to CC2 is 30 kHz, the time length corresponding to each symbol is t2, and t1=t2*2.

[0064] In the configuration method 1, as shown in Fig. 13, when the time length corresponding to the start point offset of the transmission resource cancellation indication information is T8 = 2 * t1, the time length corresponding to each symbol of CC1 is t1, and two symbols are required to reach T8, so the start point offset of the configured transmission resource cancellation indication information is 2 symbols. In addition, the time length corresponding to each symbol of CC2 is t2, and four symbols are required to reach T1, so the start point offset of the configured transmission resource cancellation indication information is 4 symbols.

[0065] In configuration method 2, the reference subcarrier spacing configured or predetermined according to a protocol is 30 kHz, and the time length corresponding to each symbol is t2. When the time length corresponding to the start point offset of the transmission resource cancellation indication information is T8=2*t1, the reference subcarrier spacing is 30 kHz, the time length corresponding to each symbol is t2, and four symbols are required to reach T8, so the start point offset of the transmission resource cancellation indication information that needs to be configured in CC1 is 2 symbols, and the start point offset of the transmission resource cancellation indication information that needs to be configured in CC2 is 4 symbols.

[0066] Exemplarily, as one example, the start point of the first reference time domain range is determined based on the last symbol of a control resource set (CORESET) in which the transmission resource cancellation indication information is arranged and a start point offset of the transmission resource cancellation indication information. Alternatively, it can be understood that the start point offset of the transmission resource cancellation indication information is a time interval from the last symbol of CORESET in which the transmission resource cancellation indication information is arranged to a time domain start point of the first reference time domain range.

[0067] The following describes a method of configuring information for determining the start point offset of the transmission resource cancellation indication information with reference to a specific example. It is necessary to configure a time domain indication granularity for two carriers (CC1 and CC2), and it is assumed that the subcarrier interval corresponding to CC1 is 15 kHz, the time length corresponding to each symbol is t1, the subcarrier interval corresponding to CC2 is 30 kHz, the time length corresponding to each symbol is t2, and t1=t2*2.

[0068] In the configuration method 1, as shown in Fig. 14, when the time length corresponding to the information for determining the start point offset of the transmission resource cancellation indication information is T8 = 2 * t1, the time length corresponding to each symbol of CC1 is t1, and two symbols are required to reach T8, so the configured information for determining the start point offset of the transmission resource cancellation indication information is 2 symbols. Also, the time length corresponding to each symbol of CC2 is t2, and four symbols are required to reach T1, so the configured information for determining the start point offset of the transmission resource cancellation indication information is 4 symbols.

[0069] In configuration method 2, the reference subcarrier spacing configured or predetermined according to a protocol is 30 kHz, and the time length corresponding to each symbol is t2. When the time length corresponding to the information for determining the start point offset of the transmission resource cancellation indication information is T8=2*t1, the reference subcarrier spacing is 30 kHz, the time length corresponding to each symbol is t2, and four symbols are required to reach T8, so the information for determining the start point offset of the transmission resource cancellation indication information that needs to be configured in CC1 is 2 symbols, and the information for determining the start point offset of the transmission resource cancellation indication information that needs to be configured in CC2 is 4 symbols.

[0070] Based on the above embodiment, the information for determining the start point offset of the transmission resource cancellation indication information is configured independently for different carriers. Or, the information for determining the start point offset of the transmission resource cancellation indication information is pre-determined according to a protocol. For example, the information for determining the start point offset of the transmission resource cancellation indication information is related to the time N2 for the terminal to process the uplink shared data channel, or the information for determining the start point offset of the transmission resource cancellation indication information is related to Tproc,2. Here, Tproc,2 is the minimum interval between the start symbol of the PUSCH and the end position of the UL grant, and its specific definition may refer to 38.214. When Tproc,2 is used to determine the start point offset of the transmission resource indication information, d 2,1 =0.

[0071] Illustratively, in some embodiments, the information for determining a start point offset of the transmission resource cancellation indication information configured for each carrier is determined based on a subcarrier spacing of each carrier and the information for determining a start point offset of the transmission resource cancellation indication information, where the information for determining a start point offset of the transmission resource cancellation indication information corresponds to a third subcarrier spacing.

[0072] Illustratively, in some embodiments, the third subcarrier spacing is configured by network equipment or the third subcarrier spacing is predetermined according to a protocol.

[0073] Illustratively, in some embodiments, the configuration information further includes third subcarrier spacing information.

[0074] Illustratively, in some embodiments, the third subcarrier spacing is the subcarrier spacing of a carrier carrying the transmission resource cancellation indication information, or the third subcarrier spacing is the minimum subcarrier spacing of the subcarrier spacings of a plurality of carriers, or the third subcarrier spacing is the maximum subcarrier spacing of the subcarrier spacings of a plurality of carriers, or the third subcarrier spacing is a reference subcarrier spacing used when configuring an SFI, or the third subcarrier spacing is the minimum subcarrier spacing of the subcarrier spacings corresponding to FR1, or the third subcarrier spacing is the maximum subcarrier spacing of the subcarrier spacings corresponding to FR1, or the third subcarrier spacing is the minimum subcarrier spacing of the subcarrier spacings corresponding to FR2, or the third subcarrier spacing is the maximum subcarrier spacing of the subcarrier spacings corresponding to FR2, or the third subcarrier spacing is a subcarrier spacing indicated by physical signaling.

[0075] The third subcarrier spacing in this embodiment is a downlink subcarrier spacing, or the third subcarrier spacing is an uplink subcarrier spacing.

[0076] Illustratively, in some embodiments, a time length corresponding to information for determining a starting point offset of the transmission resource cancellation indication information is less than or equal to a period of the search space in which the transmission resource cancellation indication information is located.

[0077] Illustratively, in some embodiments, the time lengths corresponding to the information for determining the starting point offset of the transmission resource cancellation indication information of different carriers are the same.
