Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and more particularly, to a wireless communication method and a communication device. BACKGROUND

[0002] A cross-slot scheduling mechanism is supported in a new radio (NR) system of mobile communication. The cross-slot scheduling mechanism refers to that when a radio access network (RAN) device schedules a data channel through a downlink control channel information (DCI), the data channel can not be in the same slot as the DCI, and the slot where the data channel is located can be a slot after the slot where the DCI is located. The downlink control channel specifically indicates the number of slots (which can be referred to as a slot offset) between the slot where the data channel is located and the slot where the DCI is located.

[0003] The RAN device can also configure at least one minimum slot offset for the terminal device, and indicate to apply one of the minimum slot offsets when scheduling data. The slot offset indicated by the DCI when the RAN device schedules the data channel is not less than the applied minimum slot offset. This enables the terminal device to not need to buffer the data channel (for example, a physical downlink shared channel (PDSCH)) within the minimum time offset, thereby achieving the purpose of saving the power consumption of the terminal device.

[0004] Currently, the third generation partnership project (3 rd generation partnership project,3GPP) is discussing supporting multiple scheduling modes of data channels in a carrier aggregation communication mode, for example, a DCI on one carrier can schedule data channels on two carriers, and a PDCCH that schedules a data channel on one carrier can be sent in a search space on two carriers. However, when the above scheduling modes are used, the terminal device will not be able to determine which carrier the minimum slot scheduling offset indicated by the access network device applies to when the terminal device receives the minimum slot scheduling offset. Solutions are still needed to ensure that different scheduling modes can support the application of the minimum slot offset for scheduling data channels, thereby achieving the purpose of saving the power consumption of the terminal device. SUMMARY

[0005] The present application provides a wireless communication method and a communication device, which can enable the terminal device and the network device to reach a consensus on the carrier to which the minimum time offset is applied, thereby improving the reliability of communication.

[0006] In a first aspect, a wireless communication method is provided, which can be performed by a terminal device or a module (e.g., a chip) configured to (or for) the terminal device. Hereinafter, the method is taken as an example for description.

[0007] The method comprises: receiving, by the terminal device, first indication information from a network device, the first indication information comprising at least one bit, a state of the at least one bit being a first bit state, the first bit state indicating a first minimum time offset and a second minimum time offset, wherein the first minimum time offset is a minimum time offset between first downlink control information and a first data channel on a first carrier when the first downlink control information on the first carrier schedules the first data channel, and the second minimum time offset is a minimum time offset between second downlink control information and a second data channel on the first carrier when the second downlink control information on a second carrier schedules the second data channel; determining, by the terminal device, that a first time offset is greater than or equal to the first minimum time offset, the first time offset being indicated by the first downlink control information from the network device, and the first time offset being a time offset between the first downlink control information and the first data channel; and determining, by the terminal device, that a second time offset is greater than or equal to the second minimum time offset, the second time offset being indicated by the second downlink control information from the network device, and the second time offset being a time offset between the second downlink control information and the second data channel.

[0008] According to the above scheme, it is specified that, among the two minimum time offsets indicated by the first indication information, the first minimum time offset is applicable to a scheduling manner in which the first downlink control information on the first carrier schedules the first data channel on the first carrier, and the second minimum time offset is applicable to a scheduling manner in which the second downlink control information on the second carrier schedules the second data channel on the first carrier. This can enable the network device and the terminal device to reach a consensus on the scheduling carrier (i.e., the carrier carrying the DCI) and the scheduled carrier (i.e., the carrier carrying the scheduled data channel) to which the minimum time offset is applied, so as to reduce the probability of communication failure caused by the inability of the two parties to reach a consensus, improve the reliability of communication, and implement the application of the minimum time offset mechanism in cross-time unit scheduling (e.g., cross-slot scheduling), so that it is not necessary to buffer the data channel within the minimum time offset, thereby achieving the purpose of saving power consumption of the terminal device.

[0009] In some implementations of the first aspect, the method further includes: receiving, by the terminal device, first configuration information from the network device, the first configuration information being used to configure a first list of minimum time offsets, the first list being a list of minimum time offsets between the first downlink control information and the first data channel when the first data channel is scheduled by the first downlink control information carried on the first carrier, the first list including at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel, the first minimum time offset being a minimum time offset in the first list corresponding to the first bit state.

[0010] According to the above scheme, the network device can configure a list of selectable minimum time offsets for the terminal device through the first configuration information. The network device can select one minimum time offset in the first list as the first minimum time offset according to the service condition of the terminal device, and notify the terminal device through the first indication information. The minimum time offset can be adjusted according to the communication demand. The flexibility of the application of the minimum time offset is improved.

[0011] In some implementations of the first aspect, the first bit state is further used to indicate a third minimum time offset in the first list, wherein the first minimum time offset and the third minimum time offset are respectively a minimum time offset applicable to scheduling an uplink data channel by the first downlink control channel on the first carrier and a minimum time offset applicable to scheduling a downlink data channel by the first downlink control channel on the first carrier.

[0012] According to the above scheme, the first indication information can indicate the minimum time offset between the uplink data channels scheduled by the downlink control information carried on the first carrier, which increases the flexibility of the downlink control information indication.

[0014] According to the above scheme, after receiving the first indication information, the terminal device can determine the minimum time offset corresponding to the first bit state in the first list as the first minimum time offset and the minimum time offset corresponding to the first bit state in the second list as the second minimum time offset. By having one bit state correspond to the minimum time offset in two lists, the two minimum time offsets are avoided from being indicated one by one in the first indication information, signaling overhead is reduced, and flexibility of indication of the first indication information is increased.

[0015] With reference to the first aspect, in some implementations of the first aspect, the first bit state is further used to indicate a fourth minimum time offset in the second list, where the second minimum time offset and the fourth minimum time offset are respectively minimum time offsets applicable when the second downlink control channel schedules an uplink data channel on the first carrier and when the second downlink control information schedules a downlink data channel on the first carrier.

[0016] According to the above scheme, the first indication information can indicate the respective minimum time offsets applicable when control information carried on different carriers schedules data channels on the first carrier, and can also indicate the respective minimum time offsets applicable when control information on different carriers schedules uplink data channels and downlink data channels on the first carrier, further reducing signaling overhead, increasing flexibility of indication of the first indication information, effectively implementing application of the minimum time offset mechanism in cross-time unit scheduling, and achieving the purpose of saving power consumption of the terminal device.

[0192] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: long term evolution (LTE) systems (including but not limited to LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD)), 5th generation (5G) communication systems, new radio (NR) access technologies, vehicle-to-x (V2X) communication, Internet of Vehicles, machine type communication (MTC), Internet of Things (IoT), where V2X can include vehicle to network (V2N), vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), etc.

[0193] Figure 1 is a schematic diagram of a wireless communication system 100 suitable for the embodiments of the present application.

[0194] As shown in Figure 1 , the wireless communication system 100 can include at least one network device, for example, a network device 110 as shown in Figure 1 . The wireless communication system 100 can also include at least one terminal device, for example, a terminal device 120 as shown in Figure 1 . The network device 110 and the terminal device 120 can communicate in a carrier aggregation manner.

[0195] The terminal device in the embodiments of the present application can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

[0196] It should be understood that the present application does not limit the specific form of the terminal device.

[0197] The network device in the embodiments of the present application can be any kind of device with wireless transceiving function. The device includes but is not limited to: evolved node B (eNB), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be gNB or transmission point (TRP or TP) in the 5G (such as NR) system, or one or a group (including multiple antenna panels) of antenna panels of the base station in the 5G system, or a network node constituting the gNB or the transmission point, such as a baseband unit (BBU), or a distributed unit (DU), etc.

[0198] In some deployments, a gNB can include a centralized unit (CU) and a DU. The gNB can also include an active antenna unit (AAU). The CU implements part of the functions of the gNB, and the DU implements part of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, implements the radio resource control (RRC), and the functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time services, and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer eventually becomes the information of the PHY layer, or is transformed from the information of the PHY layer, under this architecture, high-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It can be understood that the network device can be a device including one or more of the CU node, the DU node, and the AAU node. In addition, the CU can be divided into a network device in the radio access network (RAN), or can be divided into a network device in the core network (CN), which is not limited in the present application.

[0199] Currently, a cross-time unit scheduling mechanism is supported in a communication system, for example, cross-slot scheduling in NR. A network device can schedule a PDSCH in a time slot after a time slot in which a DCI (downlink control information) is located, that is, the PDSCH is not in the same time slot as the DCI. Specifically, the DCI includes time slot offset indication information, which is used to indicate the number of time slots between the time slot scheduled by the DCI and the time slot in which the DCI is located, denoted as K0. When K0>0, the DCI is not in the same time slot as the PDSCH scheduled by the DCI. After receiving the DCI, a terminal device can determine the time slot in which the PDSCH scheduled by the DCI is located according to the time slot offset indication information, which can reduce unnecessary data buffering of the terminal device and achieve the effect of saving power consumption. Similarly, the DCI scheduling a PUSCH can also indicate the number of time slots between the time slot in which the DCI is located and the time slot in which the PUSCH is located by using time slot offset indication information, denoted as K2. When K2>0, the DCI is not in the same time slot as the PUSCH scheduled by the DCI. The terminal device determines the time slot in which the scheduled PUSCH is located according to K2, and transmits uplink data on the PUSCH. In addition, the scheduling DCI sent by the network device can also include minimum time slot offset indication information. After the minimum time slot offset indicated by the minimum time slot offset indication information takes effect, the time slot offset indicated by the scheduling DCI sent by the network device will be greater than or equal to the minimum time slot offset.

[0200] When a DCI schedules data channels on multiple carriers or DCIs that schedule data channels on one carrier can be sent in search spaces on multiple carriers are supported, after a terminal device receives a minimum time slot offset indicated by a network device, the terminal device cannot determine which carrier the minimum time slot offset is applied to.

[0201] The present application provides a communication method. A minimum time offset indicated by first indication information corresponds to a carrier in a carrier aggregation communication mode, and is applied to scheduling data channels and / or reference signals on the corresponding carrier by a network device. This can enable the network device and the terminal device to reach a consensus on the carrier to which the minimum time offset is applied. When the network device uses a scheduling manner such as scheduling data channels / reference signals on multiple carriers by one DCI, or multiple carriers can carry a DCI that schedules data channels / reference signals on one carrier, in a carrier aggregation, the application of the minimum time offset mechanism of the cross-time unit scheduling (for example, cross-slot scheduling) can be implemented, and the purpose of saving power consumption of the terminal device can be achieved.

[0202] It should be noted that the embodiment of the present application takes the indication manner of the minimum time offset applicable to the scheduling of the data channel in the carrier aggregation communication mode as an example for description, and the wireless communication method provided by the present application can also be applicable to the scheduling of the reference signal. For example, the data channel in the embodiment of the present application can be replaced by the reference signal, and the minimum time offset indicated by the first indication information can be the minimum time offset applicable to the DCI scheduling of the reference signal on the corresponding carrier. For example, the reference signal can be a channel state information reference signal (CSI-RS), and when the first indication information indicates a minimum time offset applicable to the scheduling of the downlink data channel on a certain carrier, the minimum time offset is also applicable to the time offset between the DCI and the aperiodic CSI-RS (or the DCI triggers the CSI-RS to be sent) when the DCI schedules the aperiodic CSI-RS on the carrier, but the present application is not limited thereto.

[0203] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0204] In the embodiments of the present application, " / " can represent that the objects associated before and after are in an "or" relationship, for example, A / B can represent A or B; "and / or" can be used to describe the existence of three relationships of associated objects, for example, A and / or B can represent: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. In order to facilitate the description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second", etc. can be used to distinguish technical features with the same or similar functions. The "first", "second", etc. do not limit the quantity and execution order, and the "first", "second", etc. also do not necessarily mean different. In the embodiments of the present application, the words "exemplary" or "for example" are used to represent examples, illustrations or descriptions, and any embodiment or design scheme described as "exemplary" or "for example" should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. The words "exemplary" or "for example" are used to present the relevant concepts in a specific manner, and facilitate understanding. In the embodiments of the present application, at least one can also be described as one or more, and the more can be two, three, four or more, which is not limited by the present application.

[0205] Figure 2 is a schematic flowchart of the wireless communication method 200 provided by the embodiment of the present application. Figure 2The network device and the terminal device in the illustrated embodiment can communicate through a carrier aggregation communication mode to obtain a larger transmission bandwidth, in which multiple carriers of multiple cells are aggregated, a cell operating on a primary carrier is referred to as a primary cell (PCell), and a cell operating on a secondary carrier is referred to as a secondary cell. The primary cell is a cell to which the terminal device establishes an initial connection or switches through a handover process, and the secondary cell can be added when the network device performs RRC reconfiguration for the terminal device. It should be understood that a cell can correspond to a carrier on which the cell operates, and in this application, a scheduled carrier can be replaced by a scheduled cell. For example, scheduling a data channel on a first carrier can be replaced by scheduling a data channel of a first cell, and scheduling a data channel on a second carrier can be replaced by scheduling a data channel of a second cell. Specifically, the operating carrier of a cell includes an uplink carrier and a downlink carrier. Scheduling an uplink data channel on a first carrier can be replaced by scheduling a data channel on an uplink carrier of a first cell, and scheduling a downlink data channel on a first carrier can be replaced by scheduling a data channel on a downlink carrier of a first cell, but the application is not limited thereto.

[0206] It should be noted that, Figure 2 The illustrated wireless communication method 200 can be applied to a scheduling mode in which one or more carriers in a carrier aggregation communication mode each include a first search space, where the first search space is used to carry DCI scheduling a data channel on a first carrier. For ease of understanding, the following is described by way of example with 2 carriers (i.e., a first carrier and a second carrier) each including a search space for DCI scheduling a data channel on the first carrier, but the application is not limited thereto. The first carrier and the second carrier each include a first search space, and the network device can transmit DCI scheduling a data channel on the first carrier on the first carrier or transmit DCI scheduling a data channel on the first carrier on the second carrier. The terminal device needs to detect whether the network device has transmitted DCI scheduling a data channel on the first carrier in the first search space on the first carrier and the first search space on the second carrier. The first carrier and / or the second carrier can be an operating carrier of a PCell or an operating carrier of a SCell, and the application does not limit this.

[0207] S210, the network device sends first indication information to the terminal device, the first indication information indicating a first minimum time offset and a second minimum time offset.

[0208] Correspondingly, the terminal device receives the first indication information from the network device. The first minimum time offset is a minimum time offset between a first DCI and a first data channel on a first carrier when the first DCI schedules the first data channel on the first carrier. That is, the first minimum time offset is a minimum time offset between a DCI and a data channel when the network device performs same-carrier scheduling (i.e., control information and a data channel scheduled by the control information are on the same carrier) on a first carrier. The second minimum time offset is a minimum time offset between a second DCI and a second data channel on the first carrier when the second DCI schedules the second data channel on the first carrier. That is, the second minimum time offset is a minimum time offset between a DCI and a data channel when the network device performs cross-carrier scheduling (i.e., control information and a data channel scheduled by the control information are on different carriers) on a second carrier to schedule a second data channel on the first carrier.

[0209] In this application, the data channel refers to a channel or resource for carrying data. For example, the data channel can include a PDSCH and / or a PUSCH, but the application is not limited thereto.

[0210] Optionally, the minimum time offset (including the first minimum time offset and / or the second minimum time offset) can be a minimum value of the number of time units between a time unit where a DCI is located and a time unit where a data channel scheduled by the DCI is located.

[0211] As an example, the time unit is a frame, a subframe, a slot, a mini slot, or a symbol.

[0212] In one example, in an NR system, the time unit can be an NR slot, and the time length of the NR slot can be different according to different subcarrier spacings. In another example, in an LTE system, the time unit can be a subframe. For example, when a 15 kHz subcarrier spacing is used, the time length of the NR slot is equal to the time length of the subframe of the LTE system.

[0213] The following description takes the time unit of an NR slot as an example. If the first minimum time offset is N, it means that the minimum time offset between the slot where the first DCI is located and the slot where the first data channel is located is N, or in other words, the number of slots between the slot where the first DCI is located and the slot where the first data channel is located is greater than or equal to N. If the second minimum time offset is M, it means that the minimum time offset between the slot where the second DCI is located and the slot where the second data channel is located is M, or in other words, the number of slots between the slot where the second DCI is located and the slot where the second data channel is located is greater than or equal to N. However, the application is not limited thereto.

[0214] The first indication information includes at least one bit, for example, 1 bit, 2 bits, or more bits. The state of the at least one bit in the first indication information is a first bit state, and the first bit state indicates the first minimum time offset and the second minimum time offset. The at least one bit can indicate at least one state, for example, a first bit state, a second bit state, a third bit state, and the like. In one example, each state of the at least one bit can correspond to two minimum offsets, one of which is the minimum time offset applicable to the first DCI and the first data channel, and the other of which is the minimum time offset applicable to the second DCI and the second data channel. In another example, the bit states other than the first bit state of the at least one bit can not indicate the minimum time offset, be used as an indication of other functions, or be a reserved, unused bit state, but the application is not limited thereto.

[0215] Optionally, the first minimum time offset is the minimum time offset corresponding to the first bit state in the first minimum time offset group, and / or the second minimum time offset is the minimum time offset corresponding to the first bit state in the second minimum time offset group. The first minimum time offset group is a combination of multiple options of the minimum time offset between the first DCI and the first data channel when the first DCI schedules the first data channel on the first carrier, and the second minimum time offset is a combination of multiple options of the minimum time offset between the second DCI and the second data channel when the second DCI schedules the second data channel on the first carrier.

[0216] The minimum time offset group (such as the first minimum time offset group and the second minimum time offset group) can also be referred to as a minimum time offset set. In specific implementations, the minimum time offset group can be a list, and the following description takes the minimum time offset group as a list as an example, but the application is not limited thereto.

[0217] In one example, the first minimum time offset is included in a first list of minimum time offsets, the second minimum time offset is included in a second list of minimum time offsets, the first list is a list of minimum time offsets between a first DCI and a first data channel scheduled by the first DCI when the first DCI is carried on a first carrier and schedules the first data channel on the first carrier. The first list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. That is, the first data channel can be an uplink data channel on the first carrier or a downlink data channel on the first carrier. Each minimum time offset in the first list corresponds to a state of at least one bit in the first indication information. The first minimum time offset is a minimum time offset in the first list corresponding to a first bit state. The second list is a list of minimum time offsets between a second DCI and a second data channel scheduled by the second DCI when the second DCI is carried on a second carrier and schedules the second data channel on the first carrier. The second list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. That is, the second data channel can be an uplink data channel on the first carrier or a downlink data channel on the first carrier. Each minimum time offset in the second list corresponds to a state of at least one bit in the first indication information. The second minimum time offset is a minimum time offset in the second list corresponding to the first bit state.

[0218] For example, the first list includes 4 minimum time offsets applicable to scheduling an uplink data channel on the first carrier (the 4 minimum time offsets can include the same value), the first minimum time offset indicated by the first indication information is a minimum time offset between a first DCI and an uplink data channel scheduled by the first DCI when the first DCI is carried on the first carrier and schedules the uplink data channel on the first carrier. The at least one bit in the first indication information can indicate 4 bit states, each bit state corresponding to a minimum time offset in the first list. For example, the at least one bit is 2 bits, 4 bit states "00", "01", "10", "11" of the 2 bits respectively correspond to a minimum time offset in the first list, for example, as shown in Table 1, but the present application is not limited thereto.

[0219] Table 1

[0220] Bit state Minimum time offset between first DCI and uplink data channel on first carrier 00 0 01 2 10 4 11 7

[0221] The second list includes 4 minimum time offsets (the 4 minimum time offsets can include the same value) applicable to scheduling the uplink data channel on the first carrier, the first minimum time offset indicated by the first indication information is the minimum time offset between the second DCI carrying on the second carrier and the uplink data channel scheduled by the second DCI. The correspondence between the 4 minimum time offsets in the second list and the 2 bits in the first indication information can be as shown in Table 2, but the present application is not limited thereto.

[0222] Table 2

[0223] Bit state Minimum time offset between second DCI and uplink data channel on first carrier 00 2

[0224] 01 2 10 5 11 6

[0225] The 2 bits in the first indication information sent by the network device indicate "10", indicating that the first minimum time offset is the minimum time offset 4 corresponding to the bit state "10" in the first list, and the second minimum time offset is the minimum time offset 5 corresponding to the bit state "10" in the second list. When the first indication information takes effect, if the network device sends the first DCI on the first carrier, the time offset between the first DCI and the uplink data channel on the first carrier scheduled by the first DCI is greater than or equal to 4 time units. That is, when the first indication information takes effect, the time offset indicated in the first DCI is greater than or equal to 4. If the network device sends the second DCI on the second carrier, the time offset between the second DCI and the uplink data channel on the first carrier scheduled by the second DCI is greater than or equal to 5 time units. That is, when the first indication information takes effect, the time offset indicated in the second DCI is greater than or equal to 5, but the present application is not limited thereto.

[0226] For another example, the first list includes at least one minimum time offset applicable to the first DCI scheduling a downlink data channel on the first carrier, and the second list includes the second DCI scheduling a downlink data channel on the first carrier. Or, the first list includes at least one minimum time offset applicable to the first DCI scheduling an uplink data channel on the first carrier, and the second list includes the second DCI scheduling a downlink data channel on the first carrier. Or, the first list and / or the second list includes both a minimum time offset applicable to scheduling an uplink data channel and a minimum time offset applicable to scheduling a downlink data channel, the first minimum time offset being a minimum time offset applicable to scheduling an uplink data channel or a downlink data channel in the first list, and the second minimum time offset being a minimum time offset applicable to scheduling an uplink data channel or a downlink data channel in the second list, but the present application is not limited thereto.

[0227] Optionally, the first list is specified by a protocol, or the network device sends first configuration information to the terminal device, the first configuration information being used for configuring the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0228] Optionally, the second list is specified by a protocol, or the network device sends second configuration information to the terminal device, the second configuration information being used for configuring the second list. Correspondingly, the terminal device receives the second configuration information from the network device to obtain the second list.

[0229] Optionally, the first list includes both a minimum time offset applicable to scheduling an uplink data channel and a minimum time offset applicable to scheduling a downlink data channel, and the first bit state further indicates a third minimum time offset. The first minimum time offset and the third minimum time offset are respectively a minimum time offset applicable to the first DCI scheduling an uplink data channel on the first carrier and a minimum time offset applicable to the first DCI scheduling a downlink data channel on the first carrier.

[0230] For example, the first configuration information configures 2 minimum time offsets applicable to the first DCI scheduling a downlink data channel on the first carrier, 2 minimum time offsets applicable to the first DCI scheduling an uplink data channel on the first carrier, for example, the first list can be as shown in Table 3, the first indication information includes 1 bit, the 1 bit includes 2 bit states, i.e., "0" and "1", the bit state "0" of the 1 bit indicates the first minimum time offset applicable to scheduling a downlink data channel in the first configuration information and the first minimum time offset applicable to scheduling an uplink data channel in the first configuration information. The bit state "1" of the 1 bit indicates the second minimum time offset applicable to scheduling a downlink data channel in the first configuration information and the second minimum time offset applicable to scheduling an uplink data channel in the first configuration information. For example, the first minimum time offset applicable to scheduling a downlink data channel in the first configuration information is 0, the first minimum time offset applicable to scheduling an uplink data channel in the first configuration information is 4, the bit state of the 1 bit in the first indication information sent by the network device is "0", the minimum time offset between the first DCI and the downlink data channel on the first carrier scheduled by the first DCI is 0, and the minimum time offset between the first DCI and the uplink data channel on the first carrier scheduled by the first DCI is 4, i.e., the first minimum time offset and the third minimum time offset are 0 and 4 respectively. The second minimum time offset is the minimum time offset corresponding to the bit state "0" in the second list. However, the present application is not limited thereto.

[0231] Table 3

[0232]

[0233] Optionally, the second list includes both minimum time offsets applicable to scheduling an uplink data channel and minimum time offsets applicable to scheduling a downlink data channel, and the first bit state further indicates a fourth minimum time offset. The second minimum time offset and the fourth minimum time offset are respectively the minimum time offset applicable to the second DCI scheduling an uplink data channel on the first carrier and the minimum time offset applicable to the second DCI scheduling a downlink data channel on the first carrier.

[0234] For example, the second configuration information configures 2 minimum time offsets applicable to the first DCI scheduling a downlink data channel on the first carrier, 2 minimum time offsets applicable to the first DCI scheduling an uplink data channel on the first carrier, for example, the first list can be as shown in Table 4. The first indication information includes 1 bit, the 1 bit includes 2 bit states, i.e., "0" and "1", the bit state "0" of the 1 bit indicates the first minimum time offset applicable to scheduling a downlink data channel in the second configuration information, and the first minimum time offset applicable to scheduling an uplink data channel in the second configuration information. The bit state "1" of the 1 bit indicates the second minimum time offset applicable to scheduling a downlink data channel in the second configuration information, and the second minimum time offset applicable to scheduling an uplink data channel in the second configuration information, but the present application is not limited thereto.

[0235] Table 4

[0236]

[0237] For example, the first bit state of at least one bit in the first indication information can indicate the first minimum time offset, the second minimum time offset, the third minimum time offset, and the fourth minimum time offset. After the terminal device receives the first indication information, the terminal device can determine the minimum time offset satisfied when the DCI (i.e., an example of the first DCI) transmitted on the first carrier by the network device schedules an uplink data channel on the first carrier, the minimum time offset satisfied when the DCI (i.e., an example of the first DCI) transmitted on the first carrier by the network device schedules a downlink data channel on the first carrier, and the minimum time offset satisfied when the DCI (i.e., an example of the second DCI) transmitted on the second carrier by the network device schedules an uplink data channel on the first carrier, and the minimum time offset satisfied when the DCI (i.e., an example of the second DCI) transmitted on the second carrier by the network device schedules a downlink data channel on the first carrier, but the present application is not limited thereto.

[0238] In another example, the first minimum time offset and the second minimum time offset are included in a third list of minimum time offsets.

[0239] For example, the third list is as shown in Table 5, when the state of at least one bit of the first indication information transmitted by the network device is "11", the first minimum time offset is the minimum time offset 7 corresponding to the bit state "11" in Table 5, and the second minimum time offset is the minimum time offset 2 corresponding to the bit state "11" in Table 5, but the present application is not limited thereto.

[0240] Table 5

[0241]

[0242] Optionally, the third list is specified by a protocol, or the network device sends third configuration information to the terminal device, where the third configuration information is used to configure the third list. Correspondingly, the terminal device receives the third configuration information from the network device to obtain the third list.

[0243] Optionally, the first bit state further indicates the third minimum time offset and / or the fourth minimum time offset.

[0244] For example, when the first bit state further indicates the first minimum time offset, the second minimum time offset, the third minimum time offset, and the fourth minimum time offset, the third list can be as shown in Table 6.

[0245] Table 6

[0246]

[0247] Optionally, the first indication information can be carried on the first carrier or the second carrier. And / or, the first indication information is carried in DCI (denoted as DCI A) used to schedule the data channel.

[0248] Optionally, the validity time of the first indication information can be determined according to the indicated time offset A in the DCI A.

[0249] For example Figure 3 As shown in FIG. 6, the network device sends a DCI A used to schedule a data channel A, where the DCI A includes a time offset A, and the time offset A is the time offset between the DCI A and the data channel A, as shown in FIG. 6. Figure 3 As shown in FIG. 6, the time offset A is specifically the slot offset between the slot where the DCI A is located and the slot where the data channel A is located, and the time offset A is 1, that is, the slot where the data channel A is located is offset by 1 slot relative to the slot where the DCI A is located. The DCI A further includes first indication information, where the first indication information indicates the first minimum time offset and the second minimum time offset. The first indication information starts to be valid (that is, starts to apply the first minimum time offset and the second minimum time offset) from the slot indicated by the time offset A, that is, the first indication information starts to be valid from the slot where the data channel A is located. For example, the first indication information indicates that the first time offset is 3 and the second time offset is 2. After the first indication information is valid, if the network device sends a second DCI (that is, a DCI used to schedule a second data channel on the first carrier and sent on the second carrier) in a slot, the time offset between the second DCI and the second data channel indicated by the second DCI is greater than or equal to 2, as shown in FIG. 6. Figure 3As shown, the time offset indicated by the second DCI is 3. If the network device transmits a first DCI (i.e., a DCI transmitted on the first carrier for scheduling a first data channel on the first carrier) in a slot, the time offset between the first DCI and the first data channel indicated by the first DCI is greater than or equal to 3. However, the application is not limited thereto.

[0250] In S220, the terminal device determines that the first time offset is greater than or equal to the first minimum time offset, the first time offset being a time offset indicated by a first DCI from the network device.

[0251] After receiving the first indication information transmitted by the network device, according to the first time offset indicated by the first indication information, it can be determined that the first time offset indicated by the first DCI (i.e., a DCI transmitted on the first carrier for scheduling a first data channel on the first carrier) transmitted by the network device after the first indication information takes effect is greater than or equal to the first minimum time offset. The first time offset is the time offset between the first DCI and the first data channel. That is, after receiving the first indication information transmitted by the network device, the terminal device does not expect to receive a first DCI indicating a time offset less than the first minimum time offset.

[0252] After the first indication information takes effect, the terminal device receives a first DCI from the network device, the first DCI indicating a first time offset greater than or equal to the first minimum time offset.

[0253] In S230, the terminal device determines that the second time offset is greater than or equal to the second minimum time offset, the second time offset being a time offset indicated by a second DCI from the network device.

[0254] After receiving the first indication information transmitted by the network device, according to the second time offset indicated by the first indication information, it can be determined that the second time offset indicated by the second DCI (i.e., a DCI transmitted on the second carrier for scheduling a second data channel on the first carrier) transmitted by the network device after the first indication information takes effect is greater than or equal to the second minimum time offset. The second time offset is the time offset between the second DCI and the second data channel. That is, after receiving the first indication information transmitted by the network device, the terminal device does not expect to receive a second DCI indicating a time offset less than the second minimum time offset.

[0255] After the first indication information takes effect, the terminal device receives a second DCI from the network device, the second DCI indicating a second time offset greater than or equal to the second minimum time offset.

[0256] According to the foregoing scheme, the first minimum time offset indicated by the first indication information is applicable to a scheduling manner in which first downlink control information on a first carrier schedules a first data channel on the first carrier, and the second minimum time offset is applicable to a scheduling manner in which second downlink control information on a second carrier schedules a second data channel on the first carrier, so that the network device and the terminal device can reach a consensus on the minimum time offset applied to the scheduling carrier (that is, the carrier carrying the DCI) and the scheduled carrier (that is, the carrier carrying the scheduled data channel), thereby reducing the probability of communication failure caused by the failure of the communication parties to reach a consensus, improving the reliability of communication, and implementing the application of the minimum time offset mechanism in cross-time unit scheduling (for example, cross-slot scheduling), so that the terminal device can not need to buffer the data channel within the minimum time offset, and the purpose of saving power consumption of the terminal device is achieved.

[0257] Figure 4 FIG. 4 shows a schematic flowchart of a wireless communication method 400 provided by the present application. Figure 4 The network device and the terminal device in the illustrated embodiment can communicate through a carrier aggregation communication manner to obtain a larger transmission bandwidth. Figure 4 The wireless communication method 400 shown can be applied to a scheduling manner in which one or more carriers in a carrier aggregation communication manner each include a first search space, where the first search space is used to carry DCI scheduling a data channel on a first carrier. For ease of understanding, the following describes an example in which two carriers (that is, a first carrier and a second carrier) each include a search space used to carry DCI scheduling a data channel on the first carrier, but the present application is not limited thereto.

[0258] It should be noted that, in the following, Figure 4 In the illustrated embodiment, Figure 2 The same or similar description in the illustrated embodiment can be referred to the description of the foregoing Figure 2 embodiment, which will not be described herein again for brevity.

[0259] S410, the network device sends first indication information to the terminal device, where the first indication information indicates a first minimum time offset, and the first minimum time offset is a minimum time offset between DCI and a data channel scheduled by the DCI when scheduling the data channel on the first carrier.

[0260] Correspondingly, the terminal device receives the first indication information from the network device.

[0261] Optionally, before sending the first indication information, the network device sends first configuration information to the terminal device, where the first configuration information is used to configure a data scheduling manner adopted by the network device. The first configuration information is used to configure a data scheduling manner, and the data scheduling manner includes:

[0262] The first data channel on the first carrier is scheduled by the first DCI carried on the first carrier.

[0263] The second data channel on the first carrier is scheduled by the second DCI carried on the second carrier.

[0264] That is, the network device informs the terminal device of two data scheduling modes adopted by the network device in the communication process between the network device and the terminal device through the first configuration information. One data scheduling mode is to send the first DCI on the first carrier, and the first DCI schedules the first data channel on the first carrier. The other data scheduling mode is to send the second DCI on the second carrier, and the second DCI schedules the first data channel on the first carrier.

[0265] When the network device sends the first indication information and the first indication information takes effect, the time offset indicated by the first DCI (that is, the DCI used to schedule the first data channel on the first carrier) sent by the network device on the first carrier and the time offset indicated by the second DCI (that is, the DCI used to schedule the second data channel on the first carrier) sent by the network device on the second carrier are both greater than or equal to the first minimum time offset. That is, the time offset between the first DCI and the first data channel, and the time offset between the second DCI and the second data channel are both greater than or equal to the first minimum time offset.

[0266] The first indication information includes at least one bit, for example, 1 bit, 2 bits or more bits. The state of the at least one bit in the first indication information is a first bit state, and the first bit state indicates the first minimum time offset. The at least one bit can indicate at least one state, and one state can correspond to one minimum time offset applicable to the data channel on the first carrier scheduled.

[0267] Optionally, the first minimum time offset is the minimum time offset corresponding to the first bit state in the first minimum time offset group. Wherein, the first minimum time offset group is a combination of multiple optional minimum time offsets between the DCI and the data channel scheduled by the DCI when scheduling the data channel on the first carrier.

[0268] The first minimum time offset group is a combination of one or more minimum time offsets, which can also be referred to as a minimum time offset set. In specific implementation, the first minimum time offset group can be a list, and hereinafter, the minimum time offset group is taken as an example for description, and the present application is not limited thereto.

[0269] For example, the first minimum time offset is included in a first list of minimum time offsets, the first list being a list of minimum time offsets between DCI and a data channel scheduled by the DCI when scheduling the data channel on the first carrier. The first list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. That is, the first data channel can be an uplink data channel on the first carrier or a downlink data channel on the first carrier. Each minimum time offset in the first list corresponds to a state of at least one bit in the first indication information, but the application is not limited thereto.

[0270] Optionally, the first list is specified by a protocol or the network device sends first configuration information to the terminal device, the first configuration information being used to configure the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0271] For example, if the first list includes minimum time offsets applicable to downlink data channels and minimum time offsets applicable to uplink data channels in implementation, the first list can be as shown in Table 7, and the first bit state further indicates a second minimum time offset. The first minimum time offset and the second minimum time offset are respectively a minimum time offset applicable to scheduling an uplink data channel on the first carrier and a minimum time offset applicable to scheduling a downlink data channel on the first carrier. For example, the first bit state is “0” in Table 7, and when the network device sends DCI for scheduling an uplink data channel on the first carrier on the first carrier or the second carrier, the time offset indicated by the DCI is greater than or equal to the minimum time offset applicable to the uplink data channel corresponding to the first bit state “0” in Table 7. When the network device sends DCI for scheduling a downlink data channel on the first carrier on the first carrier or the second carrier, the time offset indicated by the DCI is greater than or equal to the minimum time offset applicable to the downlink data channel corresponding to the first bit state “0” in Table 7. But the application is not limited thereto.

[0272] Table 7

[0273]

[0274] For another example, if the first list includes only minimum time offsets applicable to downlink data channels, the first list can include only one column applicable to downlink data channels, i.e., not including one column applicable to uplink data channels in Table 7. If the first list includes only minimum time offsets applicable to uplink data channels, the first list can include only one column applicable to uplink data channels, i.e., not including one column applicable to downlink data channels in Table 7, but the application is not limited thereto.

[0275] Optionally, the first indication information can be carried on the first carrier or the second carrier. And / or, the first indication information is carried in DCI (denoted as DCI A) used for scheduling a data channel.

[0276] S420, the terminal device determines that both the first time offset and the second time offset are greater than or equal to the first minimum time offset, the first time offset being indicated by a first DCI indication from the network device, and the second time offset being a time offset indicated by a second DCI indication from the network device.

[0277] After the terminal device receives the first indication information, according to the first time offset indicated by the first indication information, the terminal device can determine that, after the first indication information takes effect, a first time offset indicated by a first DCI (i.e., a DCI transmitted on the first carrier for scheduling a first data channel on the first carrier) transmitted by the network device is greater than or equal to the first minimum time offset. And, the terminal device can determine that, after the first indication information takes effect, a second time offset indicated by a second DCI (i.e., a DCI transmitted on the second carrier for scheduling a second data channel on the first carrier) transmitted by the network device is greater than or equal to the first minimum time offset. That is, after the terminal device receives the first indication information transmitted by the network device, the terminal device does not expect that the time offsets indicated by the received first DCI and second DCI are less than the first minimum time offset.

[0278] After the first indication information takes effect, the terminal device receives the first DCI and / or the second DCI from the network device, wherein the first time offset indicated by the first DCI is greater than or equal to the first minimum time offset, and the second time offset indicated by the second DCI is greater than or equal to the first minimum time offset.

[0279] According to the above scheme, the first indication information indicates the minimum time offset (i.e., the first minimum time offset) applicable on the scheduled carrier (i.e., the first carrier), which enables the network device and the terminal device to reach a consensus on the carrier to which the minimum time offset applies, reduces the probability of communication failure caused by the inability of the two parties to reach a consensus, improves the reliability of communication, implements the application of the minimum time offset mechanism in cross-time unit scheduling (e.g., cross-slot scheduling), so that it is not necessary to buffer the data channel within the minimum time offset, and the terminal device saves power consumption.

[0280] Figure 5 is one illustrative flowchart of a wireless communication method 500 provided by the present application. Figure 5 The network device and the terminal device in the illustrated embodiment can communicate through a carrier aggregation communication mode to obtain a larger transmission bandwidth. Figure 5The illustrated wireless communication method 500 can be applicable to a scheduling manner in which one DCI on one carrier schedules data channels on at least two carriers in a carrier aggregation communication manner. Hereinafter, the case in which one DCI schedules data channels on two carriers is taken as an example for illustration, but the present application is not limited thereto.

[0281] It should be noted that, in the following, unless defined or described otherwise, Figure 5 In the illustrated embodiments, Figure 2 , Figure 3 The same or similar parts in the illustrated embodiments can refer to the description of the above-mentioned Figure 2 , Figure 3 embodiments for brevity, which will not be repeated here.

[0282] S510, the network device sends first indication information to the terminal device, the first indication information indicating a first minimum time offset, the first minimum time offset being a minimum time offset between a DCI and data channels scheduled by the DCI when the DCI schedules data channels on a first carrier and data channels on a second carrier.

[0283] Correspondingly, the terminal device receives the first indication information from the network device. Specifically, the network device can send a first DCI on the first carrier or the second carrier, the first DCI being used to schedule a first data channel on the first carrier and a second data channel on the second carrier. After the first indication information takes effect, the first time offset and the second time offset indicated by the first DCI are both greater than or equal to the first minimum time offset. The first time offset is a time offset between the first DCI and the first data channel indicated by the first DCI, and the second time offset is a time offset between the first DCI and the second data channel indicated by the first DCI. It should be noted that the first time offset and the second time offset can be the same time offset, i.e., the first DCI can indicate one time offset, and the first time offset and the second time offset are both the one time offset indicated by the first DCI. Alternatively, the first time offset and the second time offset can be two time offsets, i.e., the first DCI indicates two time offsets, which are the first time offset and the second time offset respectively, and the value of the first time offset and the value of the second time offset can be the same or different, which is not limited by the present application.

[0284] The first indication information includes at least one bit, for example, 1 bit, 2 bits or more bits. The state of the at least one bit in the first indication information is a first bit state, and the first bit state indicates the first minimum time offset. The at least one bit can indicate at least one state, and one state can correspond to one minimum time offset applicable to the first DCI and the data channels (including the first data channel and the second data channel) scheduled by the first DCI.

[0285] The Figure 5 The embodiments shown can include, but are not limited to, the following two implementations.

[0286] In the first implementation, the first minimum time offset is the minimum time offset corresponding to the first bit state in the first minimum time offset group. The first minimum time offset group is a combination of multiple optional minimum time offsets between the same DCI and the data channels (including the first data channel and the second data channel) scheduled by the DCI when the DCI schedules the data channels on the first carrier and the second carrier.

[0287] For example, the first minimum time offset is a first list, and the first minimum time offset is included in a first list of minimum time offsets. The first list is a list of minimum time offsets between the same DCI and the data channels (including the first data channel and the second data channel) scheduled by the DCI when the DCI schedules the data channels on the first carrier and the second carrier. The first list includes at least one minimum time offset applicable to scheduling uplink data channels and / or at least one minimum time offset applicable to scheduling downlink data channels. That is, the first minimum time offset indicated by the first indication information can be a minimum time offset applicable to uplink data channels in the first list, or a minimum time offset applicable to downlink data channels in the first list. When the first minimum time offset is a minimum time offset applicable to uplink data channels, after the first indication information takes effect, a DCI sent by the network device, if the DCI is used to schedule uplink data channels on the first carrier and uplink data channels on the second carrier, the time offset indicated by the DCI is greater than or equal to the first minimum time offset. When the first minimum time offset is a minimum time offset applicable to downlink data channels, after the first indication information takes effect, a DCI sent by the network device, if the DCI is used to schedule downlink data channels on the first carrier and downlink data channels on the second carrier, the time offset indicated by the DCI is greater than or equal to the first minimum time offset. However, the present application is not limited thereto.

[0288] Optionally, the first list is specified by a protocol, or the network device sends first configuration information to the terminal device, where the first configuration information is used to configure the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0289] For example, in a specific implementation, if the first list includes a minimum time offset applicable to a downlink data channel and a minimum time offset applicable to an uplink data channel, the first list can be as shown in Table 8, but the present application is not limited thereto. The first bit state also indicates a second minimum time offset. The first minimum time offset and the second minimum time offset are minimum time offsets applicable to a downlink data channel on a first carrier and an uplink data channel on a second carrier scheduled by a same DCI, and minimum time offsets applicable to an uplink data channel on the first carrier and a downlink data channel on the second carrier scheduled by the same DCI, respectively. For example, the first bit state is "1" in Table 8, and when the network device schedules an uplink data channel on the first carrier and an uplink data channel on the second carrier by the same DCI, the first time offset and the second time offset indicated by the DCI are both greater than or equal to the minimum time offset applicable to an uplink data channel corresponding to the bit state "1" in Table 8. When the network device schedules a downlink data channel on the first carrier and a downlink data channel on the second carrier by the same DCI, the first time offset and the second time offset indicated by the DCI are both greater than or equal to the minimum time offset applicable to a downlink data channel corresponding to the bit state "1" in Table 8. However, the present application is not limited thereto.

[0290] Table 8

[0291]

[0292]

[0293] For another example, if the first list includes only a minimum time offset applicable to a downlink data channel, the first list can be that Table 8 includes only one column applicable to a downlink data channel, i.e., Table 8 does not include a column applicable to an uplink data channel. The first minimum time offset is one minimum offset applicable to scheduling a downlink data channel in Table 8. If the first list includes only a minimum time offset applicable to an uplink data channel, the first list can be that Table 8 includes only one column applicable to an uplink data channel, i.e., Table 8 does not include a column applicable to a downlink data channel, and the first minimum time offset is one minimum offset applicable to scheduling an uplink data channel in Table 8.

[0294] In an implementation, the first mode can be applied to a case where the network device adopts a first scheduling mode. The first scheduling mode includes:

[0295] The data channel on the first carrier is scheduled by a DCI carried on the first carrier;

[0296] The data channel on the first carrier and the data channel on the second carrier are scheduled by the same DCI carried on the first carrier.

[0297] Optionally, in the case that the network device informs the terminal device to adopt the first scheduling manner, the network device configures the terminal device with the first list and a third list, the third list being a list of minimum time offsets between a DCI used for scheduling the data channel on the first carrier and the data channel on the first carrier when the data channel on the first carrier is scheduled.

[0298] The network device can indicate one minimum time offset in the third list to the terminal device as the minimum time offset between a DCI carried on the first carrier and the data channel scheduled by the DCI when the data channel on the first carrier is scheduled by the DCI.

[0299] In another implementation, the first manner can be applied to the case that the network device adopts a second scheduling manner. The second scheduling manner includes:

[0300] The data channel on the second carrier is scheduled by a DCI carried on the first carrier;

[0301] The data channel on the first carrier and the data channel on the second carrier are scheduled by the same DCI carried on the first carrier.

[0302] Optionally, in the case that the network device informs the terminal device to adopt the second scheduling manner, the network device configures the terminal device with the first list and a second list, the second list being a list of minimum time offsets between a DCI used for scheduling the data channel on the second carrier and the data channel on the second carrier when the data channel on the second carrier is scheduled.

[0303] The network device can indicate one minimum time offset in the second list to the terminal device as the minimum time offset between a DCI carried on the first carrier and the data channel scheduled by the DCI when the data channel on the second carrier is scheduled by the DCI.

[0304] Optionally, the first indication information is carried in a first DCI (i.e., a DCI that schedules both the data channel on the first carrier and the data channel on the second carrier) on the first carrier. Optionally, the effective time of the first indication information can be determined according to a first time offset or a second time offset indicated in the first DCI. That is, the first indication information starts to take effect at the time unit in which the data channel scheduled by the first DCI is located.

[0305] In the second mode, the first minimum time offset is a minimum time offset corresponding to the first bit state in a second minimum time offset group. The second minimum time offset group is a combination of multiple optional items of minimum time offset between DCI scheduling a data channel on the second carrier and the data channel on the second carrier when scheduling the data channel on the second carrier.

[0306] For example, the second minimum time offset group is the second list described above, i.e., the second list is a list of minimum time offset between DCI scheduling a data channel on the second carrier and the data channel on the second carrier when scheduling the data channel on the second carrier. The first minimum time offset is a minimum offset corresponding to the first bit state in the second list. The second list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. Each minimum time offset in the second list corresponds to a state of at least one bit in the first indication information.

[0307] Optionally, the first list is specified by a protocol, or the network device sends second configuration information to the terminal device, where the second configuration information is used to configure the second list. Correspondingly, the terminal device receives the second configuration information from the network device to obtain the second list.

[0308] In an embodiment, the second mode can be applied to the case where the network device adopts the first scheduling mode described above.

[0309] Optionally, in the case where the network device informs the terminal device to adopt the first scheduling mode, the first indication information is carried in a first DCI (i.e., DCI scheduling both a data channel on the first carrier and a data channel on the second carrier) on the first carrier. Optionally, the effective time of the first indication information can be determined according to a first time offset and / or a second time offset indicated in the first DCI. That is, the first indication information starts to take effect at the time unit where the data channel scheduled by the first DCI is located.

[0310] Optionally, in the case where the network device informs the terminal device to adopt the first scheduling mode, the network device configures the terminal device with the second list and the third list described above.

[0311] That is, the network device configures the terminal device with a list of time offsets applicable to scheduling of data channels on the first carrier and a list of time offsets applicable to scheduling of data channels on the second carrier when the network device adopts the first scheduling manner. The first indication information is carried in a first DCI (i.e., a DCI that schedules both data channels on the first carrier and data channels on the second carrier) on the first carrier. The first indication information indicates the minimum time offset corresponding to the first bit state in the second list (i.e., the list of time offsets applicable to scheduling of data channels on the second carrier) as the minimum time offset applicable to scheduling of data channels on the first carrier and data channels on the second carrier by the same first DCI.

[0312] The network device can indicate the minimum time offset in the third list to the terminal device as the minimum time offset between a DCI and data channels on the second carrier when the network device schedules the data channels on the second carrier by the DCI carried on the first carrier.

[0313] In another embodiment, the second manner can be applied to the network device adopting a third scheduling manner, which includes:

[0314] scheduling data channels on the first carrier by a DCI carried on the first carrier;

[0315] scheduling data channels on the second carrier by a DCI carried on the first carrier;

[0316] scheduling data channels on the first carrier and data channels on the second carrier by the same DCI carried on the first carrier.

[0317] Optionally, the network device configures the terminal device with the second list and the third list. The first indication information is included in an RRC message or a MAC control element (CE) signaling from the network device. The first indication information further includes an identifier of the second list, and the first indication information specifically indicates that the first minimum time interval is selected from the second list among the second list and the third list.

[0318] In the third scheduling manner, the network device can indicate the minimum time offset in the third list to the terminal device as the minimum time offset between a DCI and data channels on the first carrier when the network device schedules the data channels on the first carrier by the DCI. The network device can also indicate the minimum time offset in the second list to the terminal device as the minimum time offset between a DCI and data channels on the second carrier when the network device schedules the data channels on the second carrier by the DCI.

[0319] S520, the terminal device determines that both the first time offset and the second time offset are greater than or equal to the first minimum time offset, the first time offset and the second time offset being time offsets indicated by the first DCI from the network device.

[0320] After the terminal device receives the first indication information, according to the first time offset indicated by the first indication information, it can be determined that the first time offset and / or the second time offset of the first DCI indication from the network device after the first indication information takes effect is greater than or equal to the first minimum time offset. That is, after the terminal device receives the first indication information sent by the network device, the terminal device does not expect the time offset of the received first DCI indication to be less than the first minimum time offset.

[0321] After the first indication information takes effect, the terminal device receives the first DCI from the network device, wherein the first time offset and / or the second time offset of the first DCI indication is greater than or equal to the first minimum time offset.

[0322] According to the above scheme, it is specified that the minimum time offset indicated by the first indication information is applicable to the minimum offset between the plurality of data channels and the DCI when the plurality of data channels are scheduled by the same DCI, which can enable the network device and the terminal device to reach a consensus on the carrier to which the minimum time offset applies, thereby reducing the probability of communication failure caused by the inability of the two parties to reach a consensus, and improving the reliability of communication. In the scheduling mode of carrier aggregation, the application of the minimum time offset mechanism of cross-time unit scheduling (such as cross-slot scheduling) is realized when one DCI schedules data channels on multiple carriers, so that it is not necessary to buffer data channels within the minimum time offset, thereby achieving the purpose of saving power consumption of the terminal device.

[0323] Figure 6 is an exemplary flowchart of a wireless communication method 600 provided by the present application. Figure 6 The network device and the terminal device in the illustrated embodiment can communicate through a carrier aggregation communication mode to obtain a larger transmission bandwidth. Figure 6 The wireless communication method 600 illustrated can be applied in a carrier aggregation communication mode, and a scheduling mode of scheduling data channels on at least two carriers through one DCI on one carrier. Hereinafter, the case of scheduling data channels on two carriers through one DCI is taken as an example for description, but the present application is not limited thereto.

[0324] It should be noted that in the following, Figure 6 The same or similar parts in the illustrated embodiments can be referred to the above description of the wireless communication method 600. Figure 2 、 Figure 3 、 Figure 5 The same or similar parts in the illustrated embodiments can be referred to the above description of the wireless communication method 600.Figure 2 、 Figure 3 、 Figure 5 The description of the embodiments shown in the drawings is not exhaustive, and is not intended to limit the scope of the present application.

[0325] S610, the network device sends first indication information to the terminal device, the first indication information indicating the first minimum time offset and the second minimum time offset.

[0326] Correspondingly, the terminal device receives the first indication information from the network device. Specifically, the network device can send a first DCI on the first carrier or the second carrier, the first DCI being used to schedule a first data channel on the first carrier and a second data channel on the second carrier. After the first indication information takes effect, the first time offset indicated by the first DCI is greater than or equal to the first minimum time offset, and the second time offset indicated by the first DCI is greater than or equal to the second minimum time offset. Wherein, the first time offset is the time offset between the first DCI and the first data channel indicated by the first DCI, and the second time offset is the time offset between the first DCI and the second data channel indicated by the first DCI.

[0327] The first indication information includes at least one bit, for example, 1 bit, 2 bits or more bits. The state of the at least one bit in the first indication information is a first bit state, and the first bit state indicates the first minimum time offset and the second minimum time offset. The at least one bit can indicate at least one state, and one state can correspond to one minimum time offset applicable to the first DCI and the data channels (including the first data channel and the second data channel) scheduled by the first DCI.

[0328] Optionally, the first minimum time offset is the minimum time offset corresponding to the first bit state in the first minimum time offset group, and the second minimum time offset is the minimum time offset corresponding to the first bit state in the second minimum time offset group. Wherein, the first minimum time offset group is a combination of multiple optional items of minimum time offset between DCI and data channels scheduled by the DCI when scheduling data channels on the first carrier. The second minimum time offset group is a combination of multiple optional items of minimum time offset between DCI and data channels scheduled by the DCI when scheduling data channels on the second carrier.

[0329] For example, the first set of minimum time offsets is a first list, the first list being a list of minimum time offsets between a DCI and a data channel scheduled by the DCI when scheduling the data channel on the first carrier. The first list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. Each minimum time offset in the first list corresponds to a state of at least one bit in the first indication information. The second set of minimum time offsets is a second list, the second list being a list of minimum time offsets between a DCI and a data channel scheduled by the DCI when scheduling the data channel on the second carrier. The second list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel. Each minimum time offset in the second list corresponds to a state of at least one bit in the first indication information.

[0330] In an implementation, the first list and / or the second list is protocol specified.

[0331] In another implementation, the network device sends, to the terminal device, first configuration information for configuring the first list and / or second configuration information for configuring the second list.

[0332] Accordingly, the terminal device can obtain the first list by receiving the first configuration information from the network device. The terminal device can obtain the second list by receiving the second configuration information from the network device.

[0333] For example, if the first list includes minimum time offsets applicable to downlink data channels and minimum time offsets applicable to uplink data channels, the first list can be as shown in Table 7. If the first list includes only minimum time offsets applicable to downlink data channels, the first list can include only one column applicable to downlink data channels, i.e., not including one column in Table 7 applicable to uplink data channels. If the first list includes only minimum time offsets applicable to uplink data channels, the first list can include only one column applicable to uplink data channels, i.e., not including one column in Table 7 applicable to downlink data channels, but the present application is not limited thereto. The second list can be implemented in a similar manner to the first list, and for brevity, will not be described again here.

[0334] Optionally, the first list includes both the minimum time offset applicable to scheduling the uplink data channel and the minimum time offset applicable to scheduling the downlink data channel, and the first bit state further indicates a third minimum time offset. The first minimum time offset and the third minimum time offset are respectively: a minimum time offset applicable to the uplink data channel on the first carrier when the first DCI schedules the uplink data channel on the first carrier and the uplink data channel on the second carrier, and a minimum time offset applicable to the downlink data channel on the first carrier when the first DCI schedules the downlink data channel on the first carrier and the downlink data channel on the second carrier.

[0335] Optionally, the second list includes both the minimum time offset applicable to scheduling the uplink data channel and the minimum time offset applicable to scheduling the downlink data channel, and the first bit state further indicates a fourth minimum time offset. The second minimum time offset and the fourth minimum time offset are respectively: a minimum time offset applicable to the uplink data channel on the second carrier when the first DCI schedules the uplink data channel on the first carrier and the uplink data channel on the second carrier, and a minimum time offset applicable to the downlink data channel on the second carrier when the first DCI schedules the downlink data channel on the first carrier and the downlink data channel on the second carrier.

[0336] Optionally, Figure 6 The embodiments shown can be applicable to the case where the network device adopts a fourth scheduling mode, which includes:

[0337] The data channel on the first carrier and the data channel on the second carrier are scheduled by the same DCI carried on the first carrier.

[0338] Optionally, in the case where the network device informs the terminal device to adopt the fourth scheduling mode, the network device configures the terminal device with the first list and the second list.

[0339] That is, the network device respectively configures the minimum time offset list applicable to scheduling the data channel on the first carrier and the minimum time offset list applicable to scheduling the data channel on the second carrier, determines the first minimum time offset in the first list corresponding to the first bit state and the second minimum time offset in the second list corresponding to the second bit state through the first bit state indicated by at least one bit in the first indication information, and when the same first DCI schedules the data channel on the first carrier and the data channel on the second carrier, the time offset between the data channel on the first carrier and the first DCI is greater than or equal to the first minimum time offset, and the time offset between the data channel on the second carrier and the first DCI is greater than or equal to the second minimum time offset.

[0340] Optionally, the fourth scheduling manner can further include that the DCI carried on the first carrier schedules the data channel on the first carrier. The first minimum time offset is also the offset between the DCI scheduling the data channel on the first carrier and the data channel on the first carrier when scheduling the data channel on the first carrier.

[0341] Optionally, the fourth scheduling manner can further include that the DCI carried on the first carrier schedules the data channel on the second carrier. The second minimum time offset is also the offset between the DCI scheduling the data channel on the second carrier and the data channel on the second carrier when scheduling the data channel on the second carrier.

[0342] S620, the terminal device determines that the first time offset is greater than or equal to the first minimum time offset, and the second time offset is greater than or equal to the second minimum time offset, the first time offset and the second time offset being time offsets indicated by the first DCI from the network device.

[0343] After the terminal device receives the first indication information, according to the first time offset and the second time offset indicated by the first indication information, it can be determined that the first time offset and the second time offset of the first DCI indicated by the network device after the first indication information takes effect are greater than or equal to the first minimum time offset. That is, after the terminal device receives the first indication information sent by the network device, the terminal device does not expect the time offset of the received first DCI to be less than the first minimum time offset.

[0344] After the first indication information takes effect, the terminal device receives the first DCI from the network device, wherein the first time offset and / or the second time offset of the first DCI are greater than or equal to the first minimum time offset.

[0345] According to the above scheme, the two minimum time offsets indicated by the first indication information are respectively the minimum time offset between the data channel on the first carrier and the DCI when the DCI schedules the data channel on the first carrier and the data channel on the second carrier, and the minimum time offset between the data channel on the second carrier and the DCI, which can enable the network device and the terminal device to reach a consensus on the carrier to which the minimum time offset applies, so as to reduce the probability of communication failure caused by the inability of the two parties to reach a consensus, and improve the reliability of communication. In the scheduling manner of carrier aggregation, the application of the minimum time offset mechanism of cross-time unit scheduling (such as cross-slot scheduling) is realized when one DCI schedules data channels on multiple carriers, so that it is not necessary to buffer data channels within the minimum time offset, and the purpose of saving power consumption of the terminal device is achieved.

[0346] The embodiment of the present application further provides a wireless communication method, in the embodiment, a network device sends first indication information to a terminal device, the first indication information indicates a first minimum time offset, after the first indication information takes effect, time offsets indicated by DCI sent by the network device are all greater than or equal to the first minimum time offset, the DCI and a data channel scheduled by the DCI can be on a same carrier or can be on different carriers.

[0347] The first minimum time offset can be one of minimum time offsets configured by the network device for the terminal device. The minimum time offset list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel.

[0348] Optionally, the minimum time offset list includes both minimum time offsets applicable to scheduling an uplink data channel and minimum time offsets applicable to scheduling a downlink data channel. The first indication information further includes a second minimum time offset. The first minimum time offset and the second minimum time offset are respectively: a minimum time offset between a DCI and an uplink data channel when the DCI schedules the uplink data channel, and a minimum time offset between a DCI and a downlink data channel when the DCI schedules the downlink data channel.

[0349] Optionally, the terminal device receives second configuration information from the network device, the second configuration information is used to configure a data scheduling mode adopted by the network device, and the data scheduling mode includes one or more modes:

[0350] scheduling a data channel on a first carrier through a DCI carried on the first carrier;

[0351] scheduling a data channel on a second carrier through a DCI carried on the first carrier;

[0352] scheduling a data channel on the first carrier and a data channel on the second carrier through a same DCI carried on the first carrier.

[0353] According to the above scheme, the complexity of implementation can be reduced, the application of a minimum time offset mechanism of cross-time unit scheduling (for example, cross-slot scheduling) in a carrier aggregation communication mode can be implemented, and the purpose of saving power consumption of the terminal device is achieved.

[0354] Figure 7 FIG. 7 is a schematic flowchart of a wireless communication method 700 provided by the embodiment of the present application. Figure 7 The network device and the terminal device in the illustrated embodiment can communicate through a carrier aggregation communication mode to obtain a greater transmission bandwidth. Figure 7The illustrated wireless communication method 700 can be applicable to a scheduling manner in which a first search space is included on one or more carriers in a carrier aggregation communication manner, where the first search space is used to carry DCI scheduling a data channel on the first carrier. For ease of understanding, the following is described by way of example with the search space including DCI scheduling a data channel on the first carrier on 2 carriers (i.e., a first carrier and a second carrier), but the present application is not limited thereto.

[0355] It should be noted that, in the following, unless otherwise defined or described, Figure 7 The same or similar parts in the illustrated embodiments as in the foregoing can refer to the description in the foregoing, and for brevity, will not be described here again.

[0356] S710, the network device sends first indication information to the terminal device, where the first indication information is used to indicate a first minimum time offset.

[0357] Correspondingly, the terminal device receives the first indication information from the network device.

[0358] The first minimum time offset is a minimum time offset between the first downlink control information and the first data channel when the first downlink control information schedules the first data channel on the first carrier.

[0359] The first indication information includes at least one bit, for example, 1 bit, 2 bits or more bits. A first bit state of a state of the at least one bit indicates the first minimum time offset. The at least one bit can indicate at least one state, and one state can correspond to one minimum time offset applicable to scheduling the first data channel on the first carrier.

[0360] S720, the terminal device determines a carrier to which the first minimum time offset is applicable according to a carrier where the first indication information is located.

[0361] The terminal device can determine the carrier to which the first minimum time offset is applicable according to whether the carrier carrying the first indication information is the first carrier or the second carrier.

[0362] In an implementation manner, in a case where the first indication information is carried on the first carrier, the terminal device can determine that the first minimum time offset is a minimum time offset applicable to DCI carried on the first carrier scheduling a data channel on the first carrier. That is, the first DCI is DCI carried on the first carrier.

[0363] After the first indication information takes effect, if the terminal device receives a DCI on the first carrier, the DCI is used to schedule a data channel on the first carrier, and a time offset indicated by the DCI (i.e., a time offset between the DCI and the data channel scheduled by the DCI) is greater than or equal to the first minimum time offset. That is, after the first indication information takes effect, the terminal device does not expect to receive a DCI carried on the first carrier and used to schedule a data channel on the first carrier, and a time offset indicated by the DCI is less than the first minimum time offset.

[0364] Optionally, the first minimum time offset is a minimum time offset corresponding to the first bit state in a first minimum time offset group. The first minimum time offset group is a combination of multiple optional minimum time offsets between a DCI carried on the first carrier and a data channel scheduled by the DCI on the first carrier.

[0365] For example, the first minimum time offset is included in a first list of minimum time offsets, and the first list includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel, but the application is not limited thereto.

[0366] Optionally, the first list is specified by a protocol, or the network device sends first configuration information to the terminal device, and the first configuration information is used to configure the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0367] Optionally, the first list includes both minimum time offsets applicable to scheduling uplink data channels and minimum time offsets applicable to scheduling downlink data channels, and the first bit state further indicates a second minimum time offset. The first minimum time offset and the second minimum time offset are respectively: a minimum time offset between a DCI carried on the first carrier and an uplink data channel on the first carrier scheduled by the DCI, and a minimum time offset between a DCI carried on the first carrier and a downlink data channel on the first carrier scheduled by the DCI.

[0368] In another implementation, in a case where the first indication information is carried on the second carrier, the terminal device can determine that the first minimum time offset is a minimum time offset applicable to a DCI on the second carrier scheduling a data channel on the first carrier. That is, the first DCI is a DCI carried on the second carrier.

[0369] After the first indication information takes effect, if the terminal device receives a DCI on the second carrier, the DCI is used to schedule a data channel on the second carrier, and a time offset indicated by the DCI (that is, a time offset between the DCI and the data channel scheduled by the DCI) is greater than or equal to the first minimum time offset. That is, after the first indication information takes effect, the terminal device does not expect to receive a DCI carried on the second carrier and used to schedule a data channel on the second carrier, and a time offset indicated by the DCI is less than the first minimum time offset.

[0370] Optionally, the first minimum time offset is a minimum time offset corresponding to the first bit state in a second minimum time offset group. Wherein, the second minimum time offset group is a combination of multiple optional minimum time offsets between a DCI carried on the second carrier and a data channel scheduled by the DCI on the first carrier.

[0371] For example, the first minimum time offset is a minimum time offset corresponding to the first bit state in a second list of minimum time offsets, and the second list of minimum time offsets includes at least one minimum time offset applicable to scheduling an uplink data channel and / or at least one minimum time offset applicable to scheduling a downlink data channel, but the present application is not limited thereto.

[0372] Optionally, the second list is specified by a protocol, or the network device sends second configuration information to the terminal device, and the second configuration information is used to configure the second list. Correspondingly, the terminal device receives the second configuration information from the network device to obtain the second list.

[0373] Optionally, the first list includes both minimum time offsets applicable to scheduling uplink data channels and minimum time offsets applicable to scheduling downlink data channels, and the first bit state further indicates a third minimum time offset. The first minimum time offset and the third minimum time offset are respectively: a minimum time offset between a DCI carried on the second carrier and an uplink data channel on the first carrier scheduled by the DCI, and a minimum time offset between a DCI carried on the second carrier and a downlink data channel on the first carrier scheduled by the DCI.

[0374] According to the scheme, the carrier to which the first indication information indicates is determined according to the carrier carrying the first indication information, so as to reduce the probability of communication failure caused by the failure of the communication parties to reach a consensus, improve the reliability of communication, and enable the application of the minimum time offset mechanism of cross-time unit scheduling (for example, cross-slot scheduling) in the carrier aggregation communication mode, so that the data channel within the minimum time offset does not need to be buffered, and the purpose of saving power consumption of the terminal device is achieved.

[0375] Figure 8 FIG. 8 shows a schematic flowchart of a wireless communication method 800 provided by the present application. Figure 8 The network device and the terminal device in the embodiments shown can communicate through a carrier aggregation communication mode to obtain a larger transmission bandwidth. Figure 8 The wireless communication method 800 shown can be applied in a carrier aggregation communication mode, and a data channel on at least two carriers is scheduled through one DCI on one carrier. Hereinafter, the case of scheduling data channels on two carriers through one DCI is taken as an example for description, but the present application is not limited thereto.

[0376] It should be noted that, in the following text, unless otherwise defined or described, Figure 8 The same or similar parts in the embodiments shown as in the foregoing text can refer to the description in the foregoing text, and for brevity, will not be described here again.

[0377] S810, the network device sends a first DCI to the terminal device, the first DCI being used for scheduling a data channel, the first DCI including first indication information, the first indication information being used for indicating a first minimum time offset.

[0378] Correspondingly, the terminal device receives the first indication information from the network device.

[0379] The first indication information includes at least one bit, for example, 1 bit, 2 bits or more bits. A first bit state of a state of the at least one bit indicates the first minimum time offset. The at least one bit can indicate at least one state, and one state can correspond to one minimum time offset.

[0380] The terminal device can determine, in S820, the carrier to which the first minimum time offset is applicable according to the carrier on which the data channel scheduled by the first DCI is located.

[0381] S820, the terminal device determines, according to the carrier on which the data channel scheduled by the first DCI is located, that the first minimum time offset is applicable to scheduling a data channel on the first carrier and / or applicable to a data channel on the second carrier.

[0382] The terminal device determines a carrier to which the first minimum time offset applies according to a carrier on which the data channel scheduled by the first DCI is located. The following cases can be included.

[0383] In case one, in a case where the first DCI is used to schedule a data channel on the first carrier, the terminal device can determine that the first minimum time offset applies to scheduling the data channel on the first carrier, where the first minimum time offset is specifically a minimum time offset between the second DCI and the first data channel, the first data channel being the data channel on the first carrier, the second DCI being used to schedule the first downlink data, or the second DCI being used to schedule the first data channel and a second data channel, the second data channel being a data channel on the second carrier.

[0384] That is, if the data channel scheduled by the first DCI is carried on the first carrier (i.e., the first DCI schedules only a data channel on one carrier, and the scheduled data channel is carried on the first carrier), the first minimum time offset indicated by the first DCI is a minimum time offset between a DCI (i.e., the second DCI) scheduling a data channel on the first carrier and the data channel (i.e., the first data channel) on the first carrier scheduled by the DCI.

[0385] After the first indication information takes effect, if the terminal device receives a second DCI, the second DCI being used to schedule a data channel on the first carrier, or the second DCI being used to schedule a data channel on the first carrier and a data channel on the second carrier, the time offset indicated by the second DCI between the second DCI and the scheduled data channel on the first carrier) is greater than or equal to the first minimum time offset. That is, after the first indication information takes effect, the terminal device does not expect to receive a second DCI for scheduling a data channel on the first carrier, the time offset indicated by the second DCI being less than the first minimum time offset.

[0386] Optionally, the first minimum time offset is a minimum time offset corresponding to the first bit state in a first minimum time offset group. Wherein the first minimum time offset group is a combination of multiple optional minimum time offsets between the second DCI and the first data channel scheduled by the second DCI when the second DCI schedules a data channel on the first carrier (i.e., the first data channel).

[0387] Optionally, the first list is specified by a protocol, or the network device sends first configuration information to the terminal device, the first configuration information being used to configure the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0388] Optionally, the first list includes both the minimum time offset applicable to scheduling the uplink data channel and the minimum time offset applicable to scheduling the downlink data channel, and the first bit state further indicates a second minimum time offset. The first minimum time offset and the second minimum time offset are respectively: a minimum time offset between a second DCI and an uplink data channel on the first carrier scheduled by the second DCI when the second DCI schedules the uplink data channel on the first carrier, and a minimum time offset between a second DCI and a downlink data channel on the first carrier scheduled by the second DCI when the second DCI schedules the downlink data channel on the first carrier.

[0389] Optionally, the first list is specified by a protocol, or the network device sends first configuration information to the terminal device, the first configuration information being used for configuring the first list. Correspondingly, the terminal device receives the first configuration information from the network device to obtain the first list.

[0390] Optionally, the first list includes both the minimum time offset applicable to scheduling the uplink data channel and the minimum time offset applicable to scheduling the downlink data channel, and the first bit state further indicates a third minimum time offset. The first minimum time offset and the third minimum time offset are respectively: a minimum time offset between a DCI carried on the second carrier and an uplink data channel on the first carrier scheduled by the DCI when the DCI schedules the uplink data channel on the first carrier, and a minimum time offset between a DCI carried on the second carrier and a downlink data channel on the first carrier scheduled by the DCI when the DCI schedules the downlink data channel on the first carrier.

[0391] In case two, in a case where the first DCI is used for scheduling a data channel on the first carrier and a data channel on the second carrier, the terminal device determines that the first minimum time offset is applicable to scheduling the data channel on the second carrier, wherein the first minimum time offset is specifically a minimum time offset between a third DCI and a second data channel, the second data channel being the data channel on the second carrier, the third DCI being used for scheduling the second data channel, or the third DCI being used for scheduling a first data channel and the second data channel, the first data channel being the data channel on the first carrier.

[0392] That is, if the data channel scheduled by the first DCI is carried on the first carrier and the second carrier, the first minimum time offset indicated by the first DCI is a minimum time offset between a DCI (i.e., a third DCI) and a data channel (i.e., a second data channel) on the second carrier scheduled by the DCI when the DCI is applicable to scheduling the data channel on the second carrier.

[0393] After the first indication information takes effect, if the terminal device receives a third DCI, the third DCI is used to schedule a data channel on the second carrier, or the third DCI is used to schedule a data channel on the first carrier and a data channel on the second carrier, and the time offset indicated by the third DCI between the third DCI and the data channel on the second carrier scheduled by the third DCI is greater than or equal to the first minimum time offset. That is, after the first indication information takes effect, the terminal device does not expect to receive a third DCI used to schedule a data channel on the second carrier, and the time offset indicated by the third DCI is less than the first minimum time offset.

[0394] Optionally, the first minimum time offset is a minimum time offset corresponding to the first bit state in a second minimum time offset group. The second minimum time offset group is a combination of multiple optional minimum time offsets between the third DCI and the second data channel scheduled by the third DCI when the third DCI schedules a data channel (i.e., a second data channel) on the second carrier.

[0395] Optionally, the second list is specified by a protocol, or the network device sends second configuration information to the terminal device, and the first configuration information is used to configure the second list. Correspondingly, the terminal device receives the second configuration information from the network device to obtain the first list.

[0396] Optionally, the second list includes both minimum time offsets applicable to scheduling uplink data channels and minimum time offsets applicable to scheduling downlink data channels, and the first bit state further indicates a third minimum time offset. The first minimum time offset and the third minimum time offset are respectively: a minimum time offset between a third DCI and an uplink data channel on the second carrier scheduled by the third DCI when the third DCI schedules an uplink data channel on the second carrier, and a minimum time offset between a third DCI and a downlink data channel on the second carrier scheduled by the third DCI when the third DCI schedules a downlink data channel on the second carrier.

[0397] Optionally, the above-mentioned case one and case two can be applicable to a first scheduling manner adopted by the network device, and the first scheduling manner includes:

[0398] Scheduling a data channel on the first carrier by a DCI carried on the first carrier;

[0399] Scheduling a data channel on the first carrier and scheduling a data channel on the second carrier by the same DCI carried on the first carrier.

[0400] Optionally, the network device sends scheduling mode configuration information to the terminal device, and the scheduling mode configuration information informs the terminal device that the network device adopts the first scheduling mode. Correspondingly, the terminal device receives the scheduling mode configuration information from the network device.

[0401] The above case one and case two can be applicable to the first scheduling mode. The network device can indicate the minimum time offset applicable to scheduling the data channel on the first carrier through the DCI for scheduling the data channel on the first carrier, and indicate the minimum offset applicable to scheduling the data channel on the second carrier through the DCI for scheduling both the data channel on the first carrier and the data channel on the second carrier.

[0402] For example, when the network device adopts the first scheduling mode, the network device can indicate the minimum time offset A (an example of the first minimum time offset) applicable to scheduling the data channel (i.e., the first data channel) on the first carrier through the DCI 1 (i.e., an example of the first DCI) for scheduling the data channel on the first carrier. In the first scheduling mode, after the first indication information takes effect, when a second DCI schedules the data on the first carrier (the second DCI can be the DCI for scheduling only the data channel on the first carrier, or the DCI for scheduling both the data channel on the first carrier and the data channel on the second carrier), the time offset between the scheduled first data channel and the second DCI satisfies the minimum time offset A. The terminal device does not expect to receive a DCI for scheduling the data channel on the first carrier, which indicates a time offset less than the minimum time offset A.

[0403] When the network device adopts the first scheduling mode, the network device can only schedule the data on the second carrier through a DCI for scheduling both the data channel on the first carrier and the data channel on the second carrier. It can be specified in the first scheduling mode that the network device can indicate the minimum time offset B applicable to scheduling the data channel on the second carrier through the DCI 2 (another example of the first DCI) for scheduling both the data channel on the first carrier and the data channel on the second carrier. After the first indication information takes effect, when a third DCI schedules both the first data channel on the first carrier and the second data channel on the second carrier, the time offset between the scheduled second data channel and the second DCI satisfies the minimum offset B, and the time offset between the first data channel on the first carrier scheduled by the third DCI and the third DCI satisfies the minimum time offset applicable to scheduling the data channel on the first carrier, such as the above-mentioned minimum time offset A. The terminal device does not expect to receive a DCI for scheduling the data channel on the first carrier, which indicates a time offset less than the minimum time offset A. However, the application is not limited thereto.

[0404] The method of the embodiment can also be applicable when the network device adopts a second scheduling manner, which includes:

[0405] scheduling the data channel on the second carrier by the DCI carried on the first carrier;

[0406] scheduling the data channel on the first carrier and scheduling the data channel on the second carrier by the same DCI carried on the first carrier.

[0407] Optionally, the network device sends scheduling manner configuration information to the terminal device, the scheduling manner configuration information informing the terminal device that the network device adopts the second scheduling manner. Correspondingly, the terminal device receives the scheduling manner configuration information from the network device.

[0408] The network device can indicate the minimum time offset applicable to scheduling the data channel on the second carrier by the DCI (i.e., the DCI schedules only the data channel on one carrier, and the scheduled data channel is carried on the second carrier), and indicate the minimum offset applicable to scheduling the data channel on the first carrier by the DCI that schedules both the data channel on the first carrier and the data channel on the second carrier.

[0409] The specific implementation of the indication of the minimum time offset of the second scheduling manner is similar to the first scheduling manner described above, and can refer to the description above. For brevity, no further description is given here.

[0410] The method of the embodiment can also be applicable when the network device adopts a third scheduling manner, which includes:

[0411] scheduling the data channel on the first carrier by the DCI carried on the first carrier;

[0412] scheduling the data channel on the second carrier by the DCI carried on the first carrier;

[0413] scheduling the data channel on the first carrier and scheduling the data channel on the second carrier by the same DCI carried on the first carrier.

[0414] Optionally, the network device sends scheduling manner configuration information to the terminal device, the scheduling manner configuration information informing the terminal device that the network device adopts the third scheduling manner. Correspondingly, the terminal device receives the scheduling manner configuration information from the network device.

[0415] In a case that the network device adopts the third scheduling manner, the network device can indicate, through the DCI used for scheduling the data channel on the first carrier, a minimum time offset applicable to scheduling the data channel on the first carrier, and the network device can indicate, through the DCI used for scheduling the data channel on the second carrier, a minimum time offset applicable to scheduling the data channel on the second carrier.

[0416] In an implementation, one DCI schedules the data channel on the first carrier and the data channel on the second carrier, and the DCI does not include the first indication information indicating the minimum time offset.

[0417] In another implementation, a protocol or network configuration specifies that, in a case that one DCI schedules the data channel on the first carrier and the data channel on the second carrier, the first indication information in the DCI indicates the first minimum time offset applicable to the carrier.

[0418] Optionally, the network device sends, to the terminal device, third configuration information used for configuring, in a case that the first DCI is used for scheduling the data channel on the first carrier and the data channel on the second carrier, that the first minimum time offset is applicable to scheduling the data channel on the second carrier or the data channel on the first carrier. Correspondingly, the terminal device receives the third configuration information from the network device.

[0419] For example, the network device notifies the terminal device, through the third configuration information, that, in a case that the first DCI is used for scheduling the data channel on the first carrier and the data channel on the second carrier, the first minimum time offset is applicable to scheduling the data channel on the second carrier. When the terminal device receives one DCI 3 (that is, another example of the first DCI), the DCI 3 schedules the data channel on the first carrier and the data channel on the second carrier, and the DCI 3 includes the first indication information indicating the minimum time offset C (that is, an example of the first minimum time offset), according to the third configuration information, the terminal device can determine that the minimum time offset C indicated by the DCI 3 is the minimum time offset applicable to scheduling the data channel on the second carrier. When the minimum time offset takes effect, the network device sends, to the terminal device, a third DCI (which can be a DCI scheduling only the data channel on the second carrier, or a DCI scheduling the data channel on the first carrier and the data channel on the second carrier), and a time offset between the third DCI and the data channel on the second carrier scheduled by the third DCI is greater than or equal to the minimum time offset C. The terminal device does not expect to receive a third DCI with a time offset between the third DCI and the data channel on the second carrier scheduled by the third DCI being less than the minimum time offset C.

[0420] The network device can also notify the terminal device through the third configuration information that, in a case where the first DCI is used to schedule a data channel on the first carrier and a data channel on the second carrier, the first minimum time offset is applicable to scheduling the data channel on the first carrier. The detailed description can refer to the above description, and for brevity, will not be repeated here.

[0421] Optionally, when the network device adopts the first scheduling manner, the second scheduling manner, or the third scheduling manner, Figure 8 The first DCI, the second DCI, and the third DCI in the embodiments are all carried on the first carrier.

[0422] According to the above scheme, the carrier where the data channel scheduled according to the first indication information is located is determined as the carrier to which the minimum time offset indicated by the first indication information is applicable, which can enable the network device and the terminal device to reach a consensus on the scheduling carrier (i.e., the carrier carrying the DCI) and the scheduled carrier (i.e., the carrier carrying the scheduled data channel) to which the minimum time offset is applied, so as to reduce the probability of communication failure caused by the inability of the two parties to reach a consensus, improve the reliability of communication, and enable the application of the minimum time offset mechanism in the cross-time unit scheduling (e.g., cross-slot scheduling) in the carrier aggregation communication mode, so that it is not necessary to buffer the data channel within the minimum time offset, thereby achieving the purpose of saving power consumption of the terminal device.

In the following, in combination with Figures 9 to 11 The device provided by the embodiments of the present application is described in detail.
