[0034] 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), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication. The embodiments of this application can also be applied to these communication systems.

[0036] The communication system in this application embodiment can be applied to unlicensed spectrum, wherein unlicensed spectrum can also be considered as shared spectrum; or, the communication system in this application embodiment can also be applied to licensed spectrum, wherein licensed spectrum can also be considered as non-shared spectrum.

[0037] The embodiments of this application can be applied to both non-terrestrial networks (NTN) and terrestrial networks (TN). NTN typically uses satellite communication to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN systems, and other NTN systems may be included in the future.

[0038] Please refer to Figure 1, which shows a schematic diagram of a network architecture 100 provided in one embodiment of this application. The network architecture 100 may include: a terminal device 10, an access network device 20, and a core network element 30.

[0039] Terminal device 10 may refer to UE (User Equipment), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user equipment. In some embodiments, terminal device 10 may also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, 5GS (5 thTerminal devices in a Generation System (5G mobile communication system) or in a future evolved PLMN (Public Land Mobile Network), etc., are not limited to this embodiment. For ease of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed within the cell managed by each access network device 20. Terminal devices can also be simply referred to as terminals or UEs, the meaning of which will be understood by those skilled in the art.

[0040] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between terminal device 10 and core network element 30 through access network device 20. For example, in an LTE (Long Term Evolution) system, access network device 20 may be one or more eNodeBs in an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or EUTRAN; in a 5G NR system, access network device 20 may be one or more gNBs in a RAN (Radio Access Network). In the embodiments of this application, unless otherwise specified, the term "network device" refers to access network device 20, such as a base station.

[0041] Core network element 30 is a network element deployed in the core network. Its main functions are to provide user connectivity, manage users, and bear services, serving as an interface to external networks. For example, core network elements in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0042] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via some air interface technology, such as the NG interface in a 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as the Uu interface.

[0043] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as B5G (Beyond 5G, a fifth-generation mobile communication technology) systems, 6G systems (6G... th The sixth-generation mobile communication system can also be applied to other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, but this application does not limit it.

[0044] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a 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.

[0045] Communication systems typically support the following two downlink data transmission methods.

[0046] The first method involves the terminal device receiving downlink control signaling from the network device and then receiving downlink data transmission based on the parameters in the downlink control signaling. This scheduling method is commonly referred to as dynamic scheduling. The advantage of dynamic scheduling is that the scheduler determines the transmission parameters based on real-time traffic volume and physical channel conditions, resulting in high transmission efficiency. The terminal device first receives the downlink control signaling and then receives the downlink data channel or transmits the uplink data channel based on the parameters indicated in the downlink control signaling. However, the terminal device performs blind detection of the downlink control signaling, leading to high reception complexity. Furthermore, the processing delay at the receiving end includes both demodulating the downlink control signaling and demodulating the downlink data.

[0047] The second method involves the terminal device receiving higher-layer signaling (such as RRC (Radio Resource Control) signaling) from the network device and receiving downlink data transmission based on the parameters in this higher-layer signaling. In LTE and NR systems, this is called semi-persistent scheduling (SPS). For periodically arriving data with constant traffic volume and stable transmission conditions (e.g., no rapid movement), using semi-persistent scheduling can reduce downlink control signaling overhead and simplify reception processing at the receiver.

[0048] In 6G systems, network devices can perform pre-scheduling based on service predictions from network or terminal equipment to reduce scheduling overhead and transmission latency. However, there may be some discrepancy between the actual services arriving and the predictions. Therefore, updating the sent scheduling signaling can be considered to improve system transmission efficiency.

[0049] Please refer to Figure 2, which shows a flowchart of a wireless communication method provided in one embodiment of this application. This method can be applied to the network architecture shown in Figure 1. As shown in Figure 2, the method may include at least one of the following steps 220 to 240.

[0050] Step 220: The terminal device determines multiple first transmissions based on the first signaling.

[0051] In this embodiment, the first signaling is used to determine a plurality of first transmissions, that is, the first signaling is used to determine at least two first transmissions. The first signaling can be sent by a network device. As shown in FIG3, before the above step 220, the following step 210 is also included: the network device sends the first signaling. Optionally, the network device sends the first signaling to the terminal device, and correspondingly, the terminal device receives the first signaling sent by the network device.

[0052] When the first signaling is used to determine multiple first transmissions, these multiple first transmissions can be periodic transmissions, and the first signaling is used to activate the periodic transmissions. For example, the periodic transmissions can be any of the following: SPS PDSCH (Physical Downlink Shared Channel) transmission, CG (Configured Grant) PUSCH (Physical Uplink Shared Channel) transmission.

[0053] In cases where the first signaling is used to determine multiple first transmissions, the multiple first transmissions can also be multiple transmissions scheduled or triggered by a single first signaling, such as multiple PDSCH or PUSCH transmissions scheduled by a DCI (Downlink Control Information).

[0054] Step 240: The terminal device determines at least one second transmission based on the second signaling, the second signaling being sent after the first signaling, and the time domain start position of the at least one second transmission being before the time domain end position of the plurality of first transmissions.

[0055] In this embodiment, the second signaling is used to determine at least one second transmission. Optionally, the second transmission is different from the first transmission. The second signaling can also be sent by the network device. As shown in FIG3, before the above step 240, the following step 230 is included: the network device sends the second signaling. Optionally, the network device sends the second signaling to the terminal device, and correspondingly, the terminal device receives the second signaling sent by the network device.

[0056] In some embodiments, the second signaling is used to update at least one of the plurality of first transmissions to obtain at least one second transmission. The second transmission is determined by updating the first transmission according to the second signaling. Exemplarily, the second signaling is used to determine update parameters for the first transmission. After receiving the second signaling, the terminal device determines the update parameters for the first transmission according to the second signaling, updates the first transmission according to the update parameters, and thereby determines at least one second transmission.

[0057] In some embodiments, the second signaling is sent after the first signaling, and the interval between the time-domain position of the second signaling and the time-domain position of the first signaling is greater than or equal to a third value. The time-domain position of the first signaling can be the time-domain start position of the first signaling, or it can be understood as the time-domain start position of the channel carrying the first signaling; alternatively, the time-domain position of the first signaling can also be the time-domain end position of the first signaling, or it can be understood as the time-domain end position of the channel carrying the first signaling. Similarly, the time-domain position of the second signaling can be the time-domain start position of the second signaling, or it can be understood as the time-domain start position of the channel carrying the second signaling; alternatively, the time-domain position of the second signaling can also be the time-domain end position of the second signaling, or it can be understood as the time-domain end position of the channel carrying the second signaling.

[0058] For example, the interval between the time domain position of the second signaling and the time domain position of the first signaling is greater than or equal to a third value, which means that the interval between the time domain end position of the second signaling and the time domain end position of the first signaling is greater than or equal to a third value.

[0059] For example, the interval between the time domain position of the second signaling and the time domain position of the first signaling is greater than or equal to a third value, which means that the interval between the time domain start position of the second signaling and the time domain start position of the first signaling is greater than or equal to a third value.

[0060] For example, the interval between the time domain position of the second signaling and the time domain position of the first signaling is greater than or equal to a third value, which means that the interval between the time domain start position of the second signaling and the time domain end position of the first signaling is greater than or equal to the third value.

[0061] The aforementioned third value can be configured by network devices, reported by terminal devices, or agreed upon by protocols; this application does not limit this.

[0062] Since the second signaling is used to update the first transmission determined by the first signaling, if an update is needed immediately after the first signaling is sent, it indicates that the network device scheduling is unreasonable. From the perspective of the terminal device, such scheduling should be avoided. Therefore, the interval between the time domain position of the second signaling and the time domain position of the first signaling is greater than or equal to a third value, which can prevent the above situation from occurring.

[0063] In some embodiments, the first signaling and the second signaling are downlink control signaling (such as DCI) or MAC CE (Medium Access Control Element).

[0064] In some embodiments, the first transmission is a first channel, or the first transmission is used to transmit a first HARQ (Hybrid Automatic Repeat reQuest) process, or the first transmission is a transmission on a first resource. The first channel can be any physical channel, such as PDSCH, PUSCH, or PUCCH (Physical Uplink Control Channel). The first HARQ process corresponds to the aforementioned first channel. The first resource is the transmission resource used by the first transmission, including time-frequency resources.

[0065] In some embodiments, the second transmission and the first transmission share the same channel or carry the same HARQ process number. For example, both the second transmission and the first transmission are PDSCH, or both the second transmission and the first transmission are PUSCH.

[0066] In some embodiments, as shown in FIG3, step 240 is followed by step 250.

[0067] Step 250: The terminal device sends or receives at least one second transmission and determines the processing method for the plurality of first transmissions.

[0068] After determining at least one second transmission based on the second signaling, the terminal device can send or receive at least one second transmission. It also determines a processing method for the plurality of first transmissions. Similarly, after sending the second signaling, the network device can also receive or send at least one second transmission and determine a processing method for the plurality of first transmissions. Below, using the terminal device as an example, several possible processing methods for the plurality of first transmissions are explained. The processing method for the plurality of first transmissions by the network device is consistent with that of the terminal device.

[0069] Case 1: The terminal device cancels, abandons, or skips a first transmission in a plurality of first transmissions whose time domain start position is after the time domain start position of the first second transmission in at least one second transmission.

[0070] In this embodiment, the first second transmission in at least one second transmission refers to the first transmission with the earliest or earliest start position in the time domain among the at least one second transmission. For example, as shown in FIG4, the first signaling is DCI 1, which schedules four first transmissions, namely PDSCH 1, PDSCH 2, PDSCH 3, and PDSCH 4 in the figure. The second signaling is DCI 2, and the three second transmissions determined by DCI 2 are PDSCH 5, PDSCH 6, and PDSCH 7 in the figure. In FIG4, each PDSCH is arranged from left to right according to its time domain position from front to back. As can be seen from the figure, among the three second transmissions determined by DCI 2, the first transmission with the earliest or earliest start position in the time domain is PDSCH 5.

[0071] Furthermore, as shown in Figure 4, among the four first transmissions scheduled by DCI 1, the first transmissions whose time domain start position is after the time domain start position of PDSCH 5 include PDSCH 3 and PDSCH 4. Therefore, for case 1, the terminal device cancels, abandons, or skips the transmissions of PDSCH 3 and PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmissions of PDSCH 3 and PDSCH 4.

[0072] The handling method in scenario 1 applies to situations where, within a single carrier, cell, bandwidth portion, or frequency band, the terminal device receives or transmits at most one channel. The starting point for the second signaling scheduling to take effect is the starting point for the scheduling update, making implementation relatively simple.

[0073] Case 2: If among multiple first transmissions, there are M first transmissions whose time domain start position is before or the same as the time domain start position of the first second transmission in at least one second transmission, and which overlap with the first second transmission in the time domain or belong to the same time domain unit, then the terminal device cancels, abandons, or skips the M first transmissions, or cancels, abandons, or skips the time domain overlapping part of the M first transmissions with the first second transmission, where M is a positive integer.

[0074] In some embodiments, a first transmission and a second transmission overlapping in the time domain means that the time domain resources occupied by the first transmission and the time domain resources occupied by the second transmission have an intersection.

[0075] In some embodiments, the time domain unit can be any of the following: time slot, sub-time slot, frame, subframe, etc., and this application does not limit it. For example, a first transmission and a second transmission belonging to the same time domain unit can mean that the first transmission and the second transmission belong to the same time slot, or the same sub-time slot, or the same frame, or the same subframe, etc.

[0076] As shown in Figure 4, in the four first transmissions scheduled by DCI 1, the time-domain start position of PDSCH 2 precedes the time-domain start position of the first second transmission, PDSCH 5, and PDSCH 2 and PDSCH 5 overlap in the time domain. In this case 2, the terminal device cancels, abandons, or skips the transmission of PDSCH 2. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 2. Alternatively, in this case 2, the terminal device cancels, abandons, or skips the transmission of the time-domain overlap portion of PDSCH 2 with PDSCH 5 (i.e., the portion to the right of the dashed line in Figure 4). Similarly, the network device also cancels, abandons, or skips the transmission of the time-domain overlap portion of PDSCH 2 with PDSCH 5.

[0077] In some embodiments, Case 1 and Case 2 can be used individually, or they can be used in combination. As shown in Figure 4, when Case 1 and Case 2 are combined, the terminal device cancels, abandons, or skips the transmission of PDSCH 2, PDSCH 3, and PDSCH 4. Alternatively, the terminal device cancels, abandons, or skips the time-domain overlap portion of PDSCH 2 with PDSCH 5, as well as the transmission of PDSCH 3 and PDSCH 4. The network device does the same.

[0078] The handling method for scenario 2 considers how to handle the first transmission that overlaps with the first second transmission in the time domain or belongs to the same time domain unit, in order to avoid transmission conflicts.

[0079] Case 3: The terminal device cancels, abandons, or skips a first transmission that overlaps in the time domain with or belongs to the same time domain unit as the first second transmission in at least one second transmission, as well as subsequent first transmissions.

[0080] As shown in Figure 4, among the four first transmissions scheduled by DCI 1, the first transmission that overlaps with the first second transmission, PDSCH 5, in the time domain is PDSCH 2. The first transmissions following PDSCH 2 include PDSCH 3 and PDSCH 4. The terminal device can cancel, abandon, or skip the transmissions of PDSCH 2, PDSCH 3, and PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmissions of PDSCH 2, PDSCH 3, and PDSCH 4.

[0081] Case 4: The terminal device cancels, abandons, or skips a first transmission that overlaps with or belongs to the same time domain unit as at least one second transmission among multiple first transmissions.

[0082] As shown in Figure 4, among the four first transmissions scheduled by DCI 1, PDSCH 2 and PDSCH 5 overlap in the time domain, PDSCH 4 and PDSCH 6 overlap in the time domain, and PDSCH 3 does not overlap with any of the second transmissions. Therefore, the terminal device cancels, abandons, or skips the transmissions of PDSCH 2 and PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmissions of PDSCH 2 and PDSCH 4. Since PDSCH 3 does not overlap with any of the second transmissions, both the terminal device and the network device can transmit PDSCH 3 normally.

[0083] The handling method for scenario 4 also applies to situations where the terminal device receives or transmits at most one channel within a carrier, cell, bandwidth portion, or frequency band. The second signaling can perform updates at a finer granularity.

[0084] Case 5: If a target first transmission in multiple first transmissions and a target second transmission in at least one second transmission satisfy a predetermined condition, the terminal device cancels, abandons, or skips the target first transmission. The target first transmission includes: a first transmission whose time-domain start position is after the time-domain start position of the first second transmission in at least one second transmission, and / or a first transmission that overlaps with or belongs to the same time-domain unit as the first second transmission in the time domain. The target second transmission is either the first second transmission or any of the second transmissions.

[0085] In some embodiments, for case 5, if the target first transmission and the target second transmission do not meet the agreed conditions, the terminal device sends or receives the target first transmission. Similarly, the network device receives or sends the target first transmission.

[0086] In some embodiments, the agreed conditions include at least one of the following: the HARQ process numbers carried by the target first transmission and the target second transmission are the same; the frequency domain resources of the target first transmission and the frequency domain resources of the target second transmission overlap; the transmission direction of the target first transmission is different from the transmission direction of the target second transmission; and the priority of the target first transmission is lower than the priority of the target second transmission.

[0087] As shown in Figure 4, taking the target second transmission as the first second transmission PDSCH 5 as an example, among the four first transmissions scheduled by DCI 1, the first transmissions whose time domain start positions are after the time domain start position of PDSCH 5 are PDSCH 3 and PDSCH 4. Assuming that PDSCH 4 and PDSCH 5 meet the agreed conditions, the terminal device cancels, abandons, or skips the transmission of PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 4. Assuming that PDSCH 3 and PDSCH 5 do not meet the agreed conditions, the terminal device and network device can transmit PDSCH 3 normally.

[0088] As shown in Figure 4, taking the target second transmission as the first second transmission PDSCH 5 as an example, among the four first transmissions scheduled by DCI 1, the first transmission overlapping with PDSCH 5 in the time domain is PDSCH 2. Assuming that PDSCH 2 and PDSCH 5 meet the agreed-upon conditions, the terminal device cancels, abandons, or skips the transmission of PDSCH 2. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 2. Assuming that PDSCH 2 and PDSCH 5 do not meet the agreed-upon conditions, the terminal device and network device can transmit PDSCH 2 normally.

[0089] As shown in Figure 4, taking any second transmission as an example, such as PDSCH 6, among the four first transmissions scheduled by DCI 1, the first transmission whose time domain start position is after the time domain start position of PDSCH 6 is PDSCH 4. Assuming that PDSCH 4 and PDSCH 6 meet the agreed-upon conditions, the terminal device cancels, abandons, or skips the transmission of PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 4. If PDSCH 4 and PDSCH 6 do not meet the agreed-upon conditions, then the terminal device and network device can transmit PDSCH 4 normally.

[0090] As shown in Figure 4, taking any second transmission as an example, such as PDSCH 6, among the four first transmissions scheduled by DCI 1, the first transmission that overlaps with PDSCH 6 in the time domain is PDSCH 4. Assuming that PDSCH 4 and PDSCH 6 meet the agreed-upon conditions, the terminal device cancels, abandons, or skips the transmission of PDSCH 4. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 4. If PDSCH 4 and PDSCH 6 do not meet the agreed-upon conditions, then the terminal device and network device can transmit PDSCH 4 normally.

[0091] The handling method in scenario 5 applies to situations where the terminal equipment can receive or transmit through multiple channels within a single carrier, cell, bandwidth portion, or frequency band, or where dynamic changes in transmission direction are supported. The second signaling may be used for incremental scheduling, i.e., scheduling channels that receive or transmit simultaneously, or it may be used for scheduling updates.

[0092] Case 6: If a target first transmission in multiple first transmissions and a target second transmission in at least one second transmission meet agreed-upon conditions, the terminal device cancels, abandons, or skips the target first transmission. The target first transmission includes: a first transmission that overlaps in the time domain or belongs to the same time domain unit as at least one second transmission. The target second transmission is a second transmission that overlaps in the time domain or belongs to the same time domain unit as the target first transmission.

[0093] In some embodiments, for case 6, if the target first transmission and the target second transmission do not meet the agreed conditions, the terminal device sends or receives the target first transmission.

[0094] In some embodiments, similar to Case 5, the agreed conditions include at least one of the following: the HARQ process numbers carried by the target first transmission and the target second transmission are the same; the frequency domain resources of the target first transmission and the target second transmission overlap; the transmission direction of the target first transmission is different from the transmission direction of the target second transmission; and the priority of the target first transmission is lower than the priority of the target second transmission.

[0095] As shown in Figure 4, in the four first transmissions scheduled by DCI 1, PDSCH 2 and PDSCH 5 overlap in the time domain, and PDSCH 4 and PDSCH 6 overlap in the time domain. Assuming that PDSCH 2 and PDSCH 5 meet the agreed-upon conditions, the terminal device cancels, abandons, or skips the transmission of PDSCH 2. Similarly, the network device also cancels, abandons, or skips the transmission of PDSCH 2. Assuming that PDSCH 4 and PDSCH 6 do not meet the agreed-upon conditions, the terminal device and network device can transmit PDSCH 4 normally.

[0096] The handling method in scenario 6 applies to situations where the terminal equipment can receive or transmit through multiple channels within a single carrier, cell, bandwidth portion, or frequency band, or where dynamic changes in transmission direction are supported. The second signaling may be used for incremental scheduling, i.e., scheduling channels that receive or transmit simultaneously, or for scheduling updates. Furthermore, the second signaling can perform updates with finer granularity.

[0097] In some embodiments, the time-domain position of the second signaling precedes the time-domain start position of the first transmission that was canceled, abandoned, or skipped in a plurality of first transmissions, and the interval between the time-domain position of the second signaling and the time-domain start position of the canceled, abandoned, or skipped first transmission is greater than or equal to a first value. Optionally, the time-domain position of the second signaling is the time-domain end position of the second signaling, or can be understood as the time-domain end position of the channel carrying the second signaling. The first value may be configured by the network device, reported by the terminal device, or agreed upon by the protocol; this application does not limit this.

[0098] In some embodiments, the time-domain position of the second signaling precedes the time-domain start position of any time-domain overlap portion that has been canceled, abandoned, or skipped in a plurality of first transmissions, and the interval between the time-domain position of the second signaling and the time-domain start position of the canceled, abandoned, or skipped time-domain overlap portion is greater than or equal to a second value. Optionally, the time-domain position of the second signaling is the time-domain end position of the second signaling, or can be understood as the time-domain end position of the channel carrying the second signaling. The second value may be configured by the network device, reported by the terminal device, or agreed upon by the protocol; this application does not limit this.

[0099] By limiting the above interval to be greater than or equal to the first value / second value, it can be ensured that the terminal device has sufficient time to determine the processing method for the first transmission and / or respond to the update based on the second signaling after receiving the second signaling.

[0100] It should be understood that, when the first or second transmission is an uplink channel or signal, the terminal device sends the uplink channel or signal, and the network device receives the uplink channel or signal. When the first or second transmission is a downlink channel or signal, the network device sends the downlink channel or signal, and the terminal device receives the downlink channel or signal.

[0101] It should also be understood that, when the first or second transmission is an uplink channel or signal, the terminal device canceling, abandoning, or skipping the transmission of that uplink channel or signal means that the terminal device does not send that uplink channel or signal; the network device canceling, abandoning, or skipping the transmission of that uplink channel or signal means that the network device does not receive that uplink channel or signal. Conversely, when the first or second transmission is a downlink channel or signal, the terminal device canceling, abandoning, or skipping the transmission of that downlink channel or signal means that the terminal device does not receive that downlink channel or signal; the network device canceling, abandoning, or skipping the transmission of that downlink channel or signal means that the network device does not send that downlink channel or signal.

[0102] The technical solution provided in this application update all or part of the first transmissions among a plurality of first transmissions determined according to the first signaling through the second signaling, so that when the actual service or transmission requirements do not match the pre-scheduled transmissions, the network device can update the pre-scheduled transmissions in a timely manner, thereby helping to improve the system transmission efficiency.

[0103] In addition, in the above method embodiments, the steps executed by the terminal device can be implemented independently as a wireless communication method on the terminal device side, and the steps executed by the network device can be implemented independently as a wireless communication method on the network device side.
