[0002] With the wide application of communication technologies, there are more and more service forms in communication systems. In order to improve the utilization rate of resources to meet the transmission requirements of services, future communication systems may introduce full-duplex technology. In full-duplex technology, there may be a situation where the transmission resources for multiple services conflict, but currently there is no solution mechanism applicable to resource conflicts among multiple services in the full-duplex scenario. Summary of the Invention

The embodiments of the present application are not limited thereto. In some embodiments of the present application, the terminal device may also be a device with transceiver functions, such as a chip system. Among them, the chip system may include a chip and may also include other discrete devices.

[0085] The network device in the embodiments of the present application may refer to a device that provides wireless communication functions for terminal devices. The network device may be referred to as an access network device, such as a radio access network (RAN) device, or an access network network element, etc. Among them, the network device may support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device may be a base station (BS) (which may also be referred to as a base station device), a base transceiver station (BTS), a Node B, an evolved Node B (eNB), a device that provides base station functions in a 5G network, such as a next generation node B (gNB) and a further evolved Node B (ng-eNB), where communication between the gNB and the terminal device uses NR technology, and communication between the ng-eNB and the terminal device uses Evolved Universal Terrestrial Radio Access (E-UTRA) technology. Both the gNB and the ng-eNB can be connected to the 5G core network. In a wireless local area network (WLAN), the device that provides base station functions is an access point (AP). The network device in the embodiments of the present application also includes devices that provide wireless communication functions in future new communication systems, etc. In some embodiments, the network device may also be a device having a function of providing wireless communication for terminals, such as a chip system.

[0087] It should be understood that the “and / or” appearing in the embodiments of the present application is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character “ / ” in this article indicates that the associated objects before and after are in an “or” relationship.

[0088] The “at least one” appearing in the embodiments of the present application means one or more.

[0089] In the embodiments of the present application, "a plurality of" means two or more.

[0090] In the embodiments of the present application, the descriptions such as first and second are only for indicating and distinguishing the described objects, without an order, and do not represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application.

[0091] As described in the background art, future communication systems may introduce a communication technology of simultaneous co-frequency full-duplex to improve the utilization efficiency of time-frequency resources. Specifically, a network device and / or a terminal device may perform uplink transmission and downlink transmission on the same time-frequency resource, and such a time-frequency resource supporting uplink transmission and downlink transmission may be referred to as a simultaneous co-frequency full-duplex resource (hereinafter referred to as "full-duplex resource" for short).

[0092] In practical applications, a network device may allocate a full-duplex resource (for the convenience of distinction, this full-duplex resource is denoted as resource 1) to a terminal device for uplink transmission and downlink transmission. Alternatively, the network device may allocate resource 1 to a plurality of terminal devices for uplink transmission and downlink transmission respectively. For example, the network device may allocate resource 1 to terminal device 1 for uplink transmission and allocate resource 1 to terminal device 2 for downlink transmission.

[0093] Suppose that after the network device allocates resource 1 to terminal device 1 and / or terminal device 2, it allocates resource 2 for the burst service of terminal device 3. If resource 1 and resource 2 conflict, the network device needs to indicate the resource conflict situation to the terminal device occupying resource 1.

[0094] In view of this, the embodiments of the present application provide a communication method. The network device indicates, through conflict resource information, the resource positions corresponding to the first transmission direction and at least one serving cell to the terminal device. The first transmission direction includes uplink and / or downlink. If the resource positions indicated by the conflict resource information and the positions of the transmission resources in the first transmission direction configured by the network device for the terminal device at least partially overlap, the terminal device cancels the transmission on part or all of the resources of the transmission resources in the first transmission direction. Thus, the resource conflict problem of different terminal devices can be solved.

[0095] The following describes in detail the specific embodiments of the present application with reference to the accompanying drawings. It should be noted that the actions performed by the network device in this article may be performed by the network device, a device in the network device (such as a processor, a chip), a chip, etc., and the actions performed by the terminal device may be performed by the terminal device, a device in the terminal device (such as a processor, a chip), a chip, etc. The present application does not make any restrictions. For the convenience of description, the embodiments provided by the present application are described by taking the execution entities as the network device and the terminal device as examples.

[0096] Embodiment 1

[0097] Reference Figure 1 , Figure 1 is a signaling interaction diagram of the first communication method in the embodiments of the present application. Figure 1 The method shown includes S11, S12, and S13.

[0098] S11, the network device sends resource indication information to the first terminal device, and the resource indication information is used to indicate data transmission resources. Correspondingly, the first terminal device receives the resource indication information. For ease of distinction, the resource indication information in S11 is hereinafter denoted as the first resource indication information.

[0099] Specifically, the network device may allocate data transmission resources to the first terminal device for uplink transmission and downlink reception. Among them, the data transmission resources may be full-duplex resources.

[0100] In a specific implementation, the resource indication information may be carried in the first (Downlink Control Information, DCI). That is to say, the network device may indicate a block of full-duplex resources through a DCI, so as to implement indicating uplink transmission resources and downlink transmission resources to the first terminal device. In other words, uplink time-frequency resource allocation and downlink time-frequency resource allocation are completed through one DCI.

[0101] S12, the network device sends conflict resource information to the first terminal device, and the conflict resource information includes a direction indication field and a resource indication field. The direction indication field is used to indicate the first transmission direction, and the resource indication field is used to indicate the resource positions corresponding to at least one serving cell. Correspondingly, the first terminal device receives the conflict resource information.

[0102] In a specific implementation, the conflict resource information may be carried in the second DCI.

[0103] It should be noted that the "conflict resource information" in the embodiments of the present application may also be referred to as "resource failure information", "resource preemption information", "resource unavailable information", "resource cancellation information", "resource occupancy information", "failure indication information", "preemption indication information", "cancellation indication information", "conflict indication information", "occupancy indication information", etc. The name of the conflict resource information in this article is not limited.

[0104] Specifically, the "resource location" in this article refers to the location of the time-frequency resources preempted by the burst service. It should be noted that the burst service is the service of other terminal devices except the first terminal device. More specifically, the "resource location" in this article may refer to the location of the time-frequency resources preempted by the burst service in the reference region (RR). For the relevant description of RR, please refer to the specific description of Embodiment 4 below and will not be elaborated here. Further, the "resource location corresponding to the serving cell" refers to the location of the time-frequency resources preempted by the burst service in the serving cell. Among them, a serving cell may include one carrier, or a serving cell may include multiple carriers. The "resource location corresponding to the serving cell" in this article may also be replaced by the "resource location corresponding to the carrier".

[0105] In this article, the "location of the time-frequency resources preempted by the burst service" may be replaced by the "location of the time-frequency resources conflicting with the burst service", or replaced by the "location of the time-frequency resources overlapping with the burst service", etc.

[0106] In one example, when the transmission direction preempted by the burst service is the uplink, the "location of the time-frequency resources preempted by the burst service" may be replaced by the "location of the time-frequency resources conflicting with the burst service". When the transmission directions preempted by the burst service are the uplink and the downlink, the "resource location corresponding to the serving cell" may also be replaced by the "location of the time-frequency resources overlapping with the burst service". In addition, the "location of the time-frequency resources preempted by the burst service" in this article may be abbreviated as the "resource location preempted by the burst service". Correspondingly, the "location of the time-frequency resources conflicting with the burst service" may be abbreviated as the "resource location conflicting with the burst service", and the "location of the time-frequency resources overlapping with the burst service" may be abbreviated as the "resource location overlapping with the burst service".

[0107] Further, the first transmission direction refers to the transmission direction preempted by the burst service. If the first transmission direction is the uplink, it means that the uplink transmission on the time-frequency resources conflicting with the burst service will be completely cancelled or partially cancelled. If the first transmission direction is the downlink, it means that the downlink transmission on the time-frequency resources preempted by the burst service will be completely cancelled or partially cancelled. If the first transmission direction is the uplink and the downlink, it means that the uplink transmission on the time-frequency resources conflicting with the burst service will be completely cancelled or partially cancelled, and the downlink transmission on the time-frequency resources preempted by the burst service will be completely cancelled or partially cancelled.

[0108] It should be noted that the number of burst services in this embodiment is not limited.

[0109] In one case, the number of burst services is 1, and the transmission direction preempted by this burst service is the uplink or the downlink.

[0110] In another case, the number of burst services is 1, and the transmission directions preempted by this burst service are the uplink and the downlink.

[0111] In yet another case, the number of burst services is multiple, and the transmission directions preempted by the multiple burst services are the same. The first transmission direction refers to the transmission direction preempted by the multiple burst services.

[0112] Referring to Figure 2 , Figure 2 is a schematic diagram of the first type of second DCI in the embodiments of the present application. As Figure 2 shown, the second DCI 20 includes a direction indication field and a resource indication field 21.

[0113] Among them, the direction indication field may include multiple bits to indicate the first transmission direction.

[0114] Exemplarily, the direction indication field may include 2 bits, and the values of the 2 bits are used to indicate the first transmission direction.

[0115] In one example, among the 2 bits, one bit corresponds to the uplink and the other bit corresponds to the downlink. For example, the first bit among the 2 bits corresponds to the downlink, and the second bit among the 2 bits corresponds to the uplink. If the bit value corresponding to the uplink is 1, it means that the first transmission direction includes the uplink. If the bit value corresponding to the downlink is 1, it means that the first transmission direction includes the downlink.

[0116] In another example, if the value of the 2 bits is 00, it means that the first transmission direction is the downlink. If the value of the 2 bits is 01, it means that the first transmission direction is the uplink. If the value of the 2 bits is 10, it means that the first transmission direction is the uplink and the downlink.

[0117] Thus, the first terminal device can determine the first transmission direction based on the direction indication field.

[0118] Further, the resource indication field 21 may include at least one first subfield. Among them, each first subfield corresponds to a serving cell, and each first subfield is used to indicate the resource location corresponding to a serving cell. As Figure 2 shown, the resource indication field 21 may include N first subfields, where N is a positive integer. Thus, the resource indication field 21 can be used to indicate the resource locations corresponding to N serving cells.

[0119] The first terminal device can determine the first subfield corresponding to the serving cell where it is located from the resource indication field, and then further determine the resource location corresponding to the serving cell where it is located. For ease of description, hereinafter, the first subfield corresponding to the serving cell where the first terminal device is located is denoted as the first target subfield, and the resource location corresponding to the serving cell where the first terminal device is located is denoted as the first resource location.

[0120] The first terminal device may decode only the first target sub-domain to determine the first resource location. The first terminal device may not need to decode other first sub-domains outside the first target sub-domain.

[0121] Specifically, each first sub-domain may include K bits, where K is a positive integer. The value of K may be defined by a protocol or may be configured by a network device. The first terminal device may determine the first resource location according to the values of the K bits in the first target sub-domain and the RR configured by the network device. For the specific content on how the first terminal device may determine the first resource location according to the values in the first target sub-domain and the RR configured by the network device, reference may be made to the relevant description of Embodiment 4 below and will not be elaborated here.

[0122] S13. If the first resource location and the location of the data transmission resource at least partially overlap, the first terminal device cancels the transmission on part or all of the resources of the transmission resource in the first transmission direction.

[0123] Among them, "at least partially overlap" may include two cases: complete overlap and partial overlap.

[0124] If the first resource location and the location of the data transmission resource at least partially overlap, and the first transmission direction is the uplink, the first terminal device cancels the uplink transmission in the data transmission resource. In addition, the first terminal device may still perform downlink reception on the data transmission resource.

[0125] Among them, "canceling the uplink transmission in the data transmission resource" may mean that the uplink transmission on all resources in the data transmission resource is canceled. Or, "canceling the uplink transmission in the data transmission resource" may mean that the uplink transmission on part of the resources in the data transmission resource is canceled. When the uplink transmission on part of the resources is canceled, the uplink transmission on the resources other than the overlapping area resources in the data transmission resource is still retained. Among them, part of the resources may refer to the resources in the overlapping area between the location of the data transmission resource and the first resource location.

[0126] If the first resource location and the location of the data transmission resource at least partially overlap, and the first transmission direction is the downlink, the first terminal device cancels the downlink reception in the data transmission resource. In addition, the first terminal device may still perform uplink transmission on the data transmission resource.

[0127] Among them, "canceling downlink reception in data transmission resources" may mean that downlink reception on all resources in the data transmission resources is canceled. Or, "canceling downlink reception in data transmission resources" may mean that downlink reception on some resources in the data transmission resources is canceled. When downlink reception on some resources is canceled, downlink reception on other resources in the data transmission resources except for the resources in the overlapping area remains reserved. Among them, the some resources may refer to the resources in the overlapping area between the position of the data transmission resources and the position of the first resource.

[0128] If the position of the first resource overlaps at least partially with the position of the data transmission resources, and the first transmission direction is both uplink and downlink, the first terminal device may cancel uplink transmission in the data transmission resources and cancel downlink reception in the data transmission resources.

[0129] In the first example, the first terminal device may cancel uplink transmission on all resources of the data transmission resources and cancel downlink reception on all resources of the data transmission resources.

[0130] In the second example, the first terminal device may cancel uplink transmission on some resources of the data transmission resources and cancel downlink reception on some resources of the data transmission resources. In addition, uplink transmission and downlink reception on other resources in the data transmission resources except for the some resources are reserved.

[0131] In the third example, the first terminal device may cancel uplink transmission on all resources of the data transmission resources and cancel downlink reception on some resources of the data transmission resources. In addition, downlink reception on other resources in the data transmission resources except for the some resources is reserved.

[0132] In the fourth example, the first terminal device may cancel uplink transmission on some resources of the data transmission resources and cancel downlink reception on all resources of the data transmission resources. In addition, uplink transmission on other resources in the data transmission resources except for the some resources is reserved.

[0133] Refer to Figure 3 , Figure 3 is a schematic diagram of a resource conflict in an embodiment of the present application.

[0134] Such as Figure 3As shown, a part of the position of the data transmission resource 31 overlaps with the first resource position 32, and the overlapping part is the overlapping area 33. Exemplarily, if the first transmission direction is the uplink, the uplink transmission in the data transmission resource 31 is cancelled. If the first transmission direction is the downlink, the uplink transmission in the data transmission resource 31 is reserved, the downlink reception in the overlapping area 33 is cancelled, and the downlink reception on the resources other than the resources in the overlapping area 33 in the data transmission resource 31 is still reserved. If the first transmission direction is the uplink and the downlink, the uplink transmission in the data transmission resource 31 is cancelled, and the downlink transmission in the resources of the overlapping area 33 is cancelled, but the downlink transmission on the resources other than the resources in the overlapping area 33 in the data transmission resource 31 is still reserved.

[0135] The solution of Embodiment 1 will be described below with specific examples.

[0136] Example 1: The data transmission resources indicated by the network device are used for the enhanced mobile broadband (eMBB) uplink service and the eMBB downlink service of the first terminal device, and the burst service is the ultra-reliable low-latency communication (URLLC) downlink service.

[0137] In one case, the transmission direction preempted by the URLLC downlink service is the downlink, that is, the first transmission direction is the downlink.

[0138] In S13, if the position of the data transmission resource and the first resource position overlap at least partially, the transmission of the eMBB downlink service on the resources preempted by the URLLC downlink service in the data transmission resource is cancelled, and the transmission of the eMBB uplink service in the data transmission resource is all reserved. That is, the first terminal device ignores the eMBB downlink service data received on the resources in the overlapping area between the position of the data transmission resource and the first resource position, but the first terminal device still sends the eMBB uplink service data on the data transmission resource.

[0139] In another case, considering that the service priority of URLLC is relatively high and the eMBB uplink service may interfere with the reception of the URLLC downlink service, the transmission direction preempted by the URLLC downlink service is the uplink and the downlink. That is, the first transmission direction is the uplink and the downlink.

[0140] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmissions of eMBB uplink services in the data transmission resource are cancelled, and transmissions of eMBB downlink services on the resources in the data transmission resource pre-empted by URLLC downlink services are cancelled. That is, the first terminal device cancels sending eMBB uplink service data on the data transmission resource and ignores the eMBB downlink service data received on the resources in the overlapping area between the location of the data transmission resource and the first resource location.

[0141] Example 2: The data transmission resource indicated by the network device is used for the eMBB uplink service and URLLC downlink service of the first terminal device, and the burst service is the URLLC uplink service.

[0142] In the solution of Example 2, the transmission direction pre-empted by the URLLC uplink service is the uplink. That is, the first transmission direction is the uplink. In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmissions of eMBB uplink services in the data transmission resource are cancelled. That is, the first terminal device cancels sending eMBB uplink service data on the data transmission resource.

[0143] Example 3: The data transmission resource indicated by the network device is used for the eMBB downlink service and URLLC uplink service of the first terminal device, and the burst service is the URLLC downlink service.

[0144] In one case, the transmission direction pre-empted by the URLLC downlink service is the downlink. That is, the first transmission direction is the downlink.

[0145] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, transmissions of eMBB downlink services on the resources in the data transmission resource pre-empted by URLLC downlink services are cancelled, and all transmissions of URLLC uplink services in the data transmission resource are reserved. That is, the first terminal device ignores the eMBB downlink service data received on the resources in the overlapping area between the location of the data transmission resource and the first resource location, but the first terminal device still sends URLLC uplink service data on the data transmission resource.

[0146] In another case, considering that the priority of the URLLC downlink service may be higher than that of the URLLC uplink service and the URLLC uplink service may interfere with the reception of the URLLC downlink service, the transmission direction pre-empted by the URLLC downlink service is the uplink and the downlink. That is, the first transmission direction is the uplink and the downlink.

[0147] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmissions of URLLC uplink services in the data transmission resource are cancelled, and the transmissions of eMBB downlink services on the resources preempted by URLLC downlink services in the data transmission resource are cancelled. That is, the first terminal device cancels the transmission of URLLC uplink service data on the data transmission resource, and ignores the eMBB downlink service data received on the resources in the overlapping area between the location of the data transmission resource and the first resource location.

[0148] Example 4: The data transmission resource indicated by the network device is used for the eMBB downlink service and eMBB uplink service of the first terminal device, and the burst service is the URLLC downlink service and URLLC uplink service.

[0149] In the solution of Example 4, the transmission directions preempted by the burst service are uplink and downlink. That is, the first transmission direction is uplink and downlink. In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmissions of eMBB uplink services in the data transmission resource are cancelled, and the transmissions of eMBB downlink services on the resources preempted by the burst service in the data transmission resource are cancelled. That is, the first terminal device cancels the transmission of eMBB uplink service data on the data transmission resource, and ignores the eMBB downlink service data received on the resources in the overlapping area between the location of the data transmission resource and the first resource location.

[0150] As above, in the solution of Embodiment 1, the network device allocates data transmission resources for the first terminal device for uplink transmission and downlink reception. If the resource location preempted by the burst service of other terminal devices conflicts with the data transmission resource, the network device sends conflict resource information to the first terminal device, and the first terminal device can determine the direction preempted by the burst service and the resource location preempted by the burst service based on the conflict resource information. If the first transmission direction includes downlink, the first terminal device can cancel the downlink reception on the preempted resource location in the data transmission resource, or rather, the first terminal device ignores the data received on the preempted resource location, and then improves the decoding success rate by padding with zeros. If the first transmission direction includes uplink, the first terminal device can cancel all uplink transmissions on the data transmission resource to avoid the collision of uplink transmissions of different services.

[0151] For more content about Embodiment 1, reference can be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0152] Embodiment 2

[0153] Refer to Figure 4 , Figure 4 which is a signaling interaction diagram of the second communication method in the embodiments of the present application. Figure 4The method shown includes S41, S42, and S43.

[0154] S41, the network device sends uplink resource indication information and / or downlink resource indication information to the first terminal device. Correspondingly, the first terminal device receives the uplink resource indication information and / or the downlink resource indication information.

[0155] Specifically, the network device can allocate uplink transmission resources for the first terminal device to perform uplink transmission through the uplink resource indication information, and / or, the network device can allocate downlink transmission resources for the first terminal device to perform downlink reception through the downlink resource indication information.

[0156] In a specific implementation, the uplink resource indication information and the downlink resource indication information can be carried in the same signaling. For example, they can be carried in different fields of the same signaling (such as DCI). Or, the uplink resource indication information and the downlink resource indication information can be carried in different signals. Exemplarily, the uplink resource indication information and the downlink resource indication information can be carried in different DCIs. For example, the uplink resource indication information can be carried in DCI 0_1, and the downlink resource indication information is carried in DCI 1_1. It should be noted that the network device can send the uplink resource indication information and the downlink resource indication information simultaneously; or, the network device can first send the uplink resource indication information and then send the downlink resource indication information; or, the network device can first send the downlink resource indication information and then send the uplink resource indication information.

[0157] Refer to Figure 5 , Figure 5 is a schematic diagram of a resource allocation in an embodiment of the present application. As Figure 5 shown, the uplink transmission resource 51 and the downlink transmission resource 52 can at least partially overlap.

[0158] In a specific implementation, the uplink transmission resource 51 can be allocated to the first terminal device, and the downlink transmission resource 52 can be allocated to the second terminal device. Or, the downlink transmission resource 52 can be allocated to the first terminal device, and the uplink transmission resource 51 can be allocated to the second terminal device. Or, the uplink transmission resource 51 and the downlink transmission resource 52 can be allocated to the first terminal device.

[0159] Continue to refer to Figure 4 S42, the network device sends conflict resource information to the first terminal device. The conflict resource indication information includes a direction indication field and a resource indication field. The direction indication field is used to indicate the first transmission direction, and the resource indication field is used to indicate the uplink resource position and / or the downlink resource position corresponding to at least one serving cell.

[0160] Among them, the "uplink resource location corresponding to the serving cell" refers to the location of the uplink time-frequency resources preempted by the burst service within the serving cell. Alternatively, the "uplink resource location corresponding to the serving cell" may refer to the location of the uplink time-frequency resources conflicting with the burst service within the serving cell. A serving cell may include one carrier, or a serving cell may include multiple carriers. The "uplink resource location corresponding to the serving cell" in this article may also be replaced by the "uplink resource location corresponding to the carrier".

[0161] The "downlink resource location corresponding to the serving cell" refers to the location of the downlink time-frequency resources preempted by the burst service within the serving cell. The "downlink resource location corresponding to the serving cell" in this article may also be replaced by the "downlink resource location corresponding to the carrier".

[0162] The uplink resource location refers to the location of the uplink time-frequency resources conflicting with the burst service, and the downlink resource location refers to the location of the downlink time-frequency resources preempted by the burst service. More specifically, the "uplink resource location" in this article may refer to the location of the time-frequency resources conflicting with the burst service within the RR, or may refer to the location of the time-frequency resources conflicting with the burst service within the Reference Uplink Region (RUR). The "downlink resource location" in this article may refer to the location of the time-frequency resources preempted by the burst service within the RR, or may refer to the location of the time-frequency resources preempted by the burst service within the Reference Downlink Region (RDR). For the relevant description of the RR, please refer to the specific description of Embodiment 4 below. For the relevant description of the RUR and RDR, please refer to the specific description of Embodiment 5 below, which will not be elaborated here.

[0163] The "location of the time-frequency resources preempted by the burst service" in this article may be abbreviated as the "resource location preempted by the burst service". Correspondingly, the "location of the time-frequency resources conflicting with the burst service" may be abbreviated as the "resource location conflicting with the burst service".

[0164] Refer to Figure 6 , Figure 6 is a schematic diagram of the second type of second DCI in the embodiments of the present application.

[0165] Such as Figure 6As shown, the second DCI 60 includes a direction indication field and a resource indication field 61. The resource indication field 61 includes N first sub-fields 611, where N is a positive integer. Each first sub-field 611 corresponds to a serving cell, and each first sub-field 611 is used to indicate a resource location corresponding to a serving cell. Further, each first sub-field 611 may include a first uplink sub-field and / or a first downlink sub-field, the resource location indicated by the first uplink sub-field is an uplink resource location, and the resource location indicated by the first downlink sub-field is a downlink resource location.

[0166] Specifically, the first uplink subdomain may include K1 bit values, and the first downlink subdomain may include K2 bit values, where K1 is a positive integer and K2 is a positive integer. The value of K1 may be defined by a protocol or may be configured by a network device. The value of K2 may be defined by a protocol or may be configured by a network device. In one example, K1=K2.

[0167] Further, the first terminal device may determine the first target sub-domain from the resource indication domain.

[0168] If the direction indication field indicates that the first transmission direction is uplink, the first terminal device may only decode the first uplink subfield in the first target subfield. The first terminal device may not need to decode the first downlink subfield in the first target subfield.

[0169] Specifically, the first terminal device can determine the uplink resource position corresponding to the serving cell where the first terminal device is located according to the value of the first uplink sub-domain in the first target sub-domain. For ease of description, the uplink resource position corresponding to the serving cell where the first terminal device is located is denoted as the first uplink resource position. Figure 6 If the second first sub-domain is the first target sub-domain and the first transmission direction is uplink, the first terminal device can only decode the first uplink sub-domain 2 to determine the first uplink resource position.

[0170] In addition, if the first transmission direction is uplink, that is, the burst service only occupies the uplink, the network device can set the value of the first downlink subfield in each first subfield to 0. Alternatively, if the first transmission direction is uplink, each first subfield in the conflicting resource information can only include the first uplink subfield, and does not include the first downlink subfield. This can reduce the length of the conflicting resource information, which is conducive to saving signaling overhead.

[0171] If the direction indication field indicates that the first transmission direction is downlink, the first terminal device may only decode the first downlink subfield in the first target subfield. The first terminal device may not need to decode the first uplink subfield in the first target subfield.

[0172] Specifically, the first terminal device can determine the downlink resource location corresponding to the serving cell it is in according to the value of the first downlink sub-domain in the first target sub-domain. For ease of description, hereinafter, the downlink resource location corresponding to the serving cell where the first terminal device is located is denoted as the first downlink resource location. Suppose Figure 6 the second first sub-domain in Figure 6 is the first target sub-domain, and the first transmission direction is downlink, then the first terminal device can only decode the first downlink sub-domain 2 to determine the first downlink resource location.

[0173] In addition, if the first transmission direction is downlink, that is, the burst service only occupies the downlink, the network device can set the values of the first uplink sub-domains in each first sub-domain to 0. Or, if the first transmission direction is downlink, each first sub-domain in the conflict resource information can only include the first downlink sub-domain and does not include the first uplink sub-domain. This can reduce the length of the conflict resource information and is beneficial to saving signaling overhead.

[0174] If the direction indication field indicates that the first transmission direction is uplink and downlink, the first terminal device can decode the first uplink sub-domain and the first downlink sub-domain in the first target sub-domain. The first terminal device can determine the first uplink resource location according to the value of the first uplink sub-domain in the first target sub-domain, and determine the first downlink resource location according to the value of the first downlink sub-domain in the first target sub-domain.

[0175] For the specific content on how the first terminal device can determine the first uplink resource location according to the value of the first uplink sub-domain, and for the specific content on determining the first downlink resource location according to the value of the first downlink sub-domain, reference can be made to the relevant descriptions of Embodiment 4 and Embodiment 5 below, which will not be elaborated here.

[0176] Refer to Figure 7 , Figure 7 which is a schematic diagram of the third second DCI in the embodiments of the present application.

[0177] As Figure 7 shown, the second DCI 70 includes a direction indication field and a resource indication field 71. Among them, the resource indication field 71 includes a second uplink sub-domain and a second downlink sub-domain. The second uplink sub-domain is used to indicate the uplink resource location corresponding to at least one serving cell, and the second downlink sub-domain is used to indicate the downlink resource location corresponding to at least one serving cell.

[0178] Among them, the second uplink sub-domain includes N second sub-domains, N is a positive integer, each second sub-domain is used to indicate the uplink resource location corresponding to a serving cell, and the second downlink sub-domain includes N third sub-domains, and each third sub-domain is used to indicate the downlink resource location corresponding to a serving cell.

[0179] Specifically, the second sub-domain may include K3 bit values, and the third sub-domain may include K4 bit values, where K3 is a positive integer and K4 is a positive integer. The value of K3 can be defined by a protocol or can be configured by a network device. The value of K4 can be defined by a protocol or can be configured by a network device. In one example, K3 = K4.

[0180] If the direction indication field indicates that the first transmission direction is uplink, the first terminal device can determine the second sub-domain corresponding to the serving cell it belongs to from the second uplink sub-domain. For ease of description, hereinafter, the second sub-domain corresponding to the serving cell where the first terminal device is located is denoted as the second target sub-domain. Further, the first terminal device can decode the second target sub-domain and determine the first uplink resource location according to the value of the second target sub-domain. The first terminal device does not need to decode other second sub-domains in the second uplink sub-domain except the second target sub-domain, nor does it need to decode the second downlink sub-domain. Suppose Figure 7 the second sub-domain 2 in is the second target sub-domain, then the first terminal device can only decode the second sub-domain 2.

[0181] In addition, if the first transmission direction is uplink, that is, the burst service only preempts the uplink, the network device can set the value of the second downlink sub-domain to 0. Or, if the first transmission direction is uplink, the resource indication field in the conflict resource information can only include the second uplink sub-domain and does not include the second downlink sub-domain. This can reduce the length of the conflict resource information and is beneficial to saving signaling overhead.

[0182] If the direction indication field indicates that the first transmission direction is downlink, the first terminal device can determine the third sub-domain corresponding to the serving cell it belongs to from the second downlink sub-domain. For ease of description, hereinafter, the third sub-domain corresponding to the serving cell where the first terminal device is located is denoted as the third target sub-domain. Further, the first terminal device can decode the third target sub-domain and determine the first downlink resource location according to the value of the third target sub-domain. The first terminal device does not need to decode other third sub-domains in the second downlink sub-domain except the third target sub-domain, nor does it need to decode the second uplink sub-domain. Suppose Figure 7 the third sub-domain 2 in is the third target sub-domain, then the first terminal device can only decode the third sub-domain 2.

[0183] In addition, if the first transmission direction is downlink, that is, the burst service only preempts the downlink, the network device can set the value of the second uplink sub-domain to 0. Or, if the first transmission direction is uplink, the resource indication field in the conflict resource information can only include the second downlink sub-domain and does not include the second uplink sub-domain. This can reduce the length of the conflict resource information and is beneficial to saving signaling overhead.

[0184] If the direction indication field indicates that the first transmission direction is both uplink and downlink, the first terminal device may determine a second target subfield from the second uplink subfield and a third target subfield from the second downlink subfield. Further, the first terminal device decodes the second target subfield and the third target subfield, determines the first uplink resource position according to the value of the second target subfield, and determines the first downlink resource position according to the value of the third target subfield.

[0185] For the specific content on how the first terminal device can determine the first uplink resource position according to the value of the second target subfield and the specific content on determining the first downlink resource position according to the value of the third target subfield, reference may be made to the relevant descriptions of Embodiment 4 and Embodiment 5 below, which will not be elaborated here.

[0186] In S43, if the first transmission direction includes uplink and the first uplink resource position at least partially overlaps with the position of the uplink transmission resource, the uplink transmission on part or all of the resources of the uplink transmission resource is cancelled; and / or, if the first transmission direction includes downlink and the first downlink resource position at least partially overlaps with the position of the downlink transmission resource, the downlink reception on part or all of the resources of the downlink transmission resource is cancelled.

[0187] Specifically, if the first uplink resource position at least partially overlaps with the position of the uplink transmission resource and the first transmission direction includes uplink, the first terminal device may cancel the uplink transmission in the uplink transmission resource. Further, if the first transmission direction does not include downlink and the uplink transmission resource and the downlink transmission resource at least partially overlap, the downlink reception on the resources in the overlapping area of the uplink transmission resource and the downlink transmission resource may still be retained.

[0188] Herein, "cancelling the uplink transmission in the uplink transmission resource" may mean that the uplink transmission on all resources in the uplink transmission resource is cancelled. Or, "cancelling the uplink transmission in the uplink transmission resource" may mean that the uplink transmission on part of the resources in the uplink transmission resource is cancelled. When the uplink transmission on part of the resources is cancelled, the uplink transmission on the other resources in the uplink transmission resource except the part of the resources is still retained. Herein, the part of the resources may refer to the resources in the overlapping area of the position of the uplink transmission resource and the first uplink resource position.

[0189] If the first resource position at least partially overlaps with the position of the downlink transmission resource and the first transmission direction includes downlink, the first terminal device may cancel the downlink reception in the downlink transmission resource. Further, if the first transmission direction does not include uplink and the uplink transmission resource and the downlink transmission resource at least partially overlap, the uplink transmission on the resources in the overlapping area of the uplink transmission resource and the downlink transmission resource may still be retained.

[0190] Among them, "canceling downlink reception in the downlink transmission resource" may mean that downlink reception on all resources in the downlink transmission resource is canceled. Alternatively, "canceling downlink reception in the downlink transmission resource" may mean that downlink reception on some resources in the downlink transmission resource is canceled. When downlink reception on some resources is canceled, downlink reception on other resources in the downlink transmission resource except for the some resources is still retained. Among them, the some resources may refer to the resources in the overlapping area between the position of the downlink transmission resource and the position of the first downlink resource.

[0191] For more content about the second embodiment, reference can be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0192] Embodiment 3

[0193] Refer to Figure 8 , Figure 8 is a signaling interaction diagram of the third communication method in the embodiments of the present application. Figure 8 The method shown includes S81, S82, and S83.

[0194] S81, the network device sends uplink resource indication information and / or downlink resource indication information to the first terminal device. Correspondingly, the first terminal device receives the uplink resource indication information and / or the downlink resource indication information.

[0195] Specifically, the network device may allocate uplink transmission resources for the first terminal device to perform uplink transmission through the uplink resource indication information, and / or, the network device may allocate downlink transmission resources for the first terminal device to perform downlink reception through the downlink resource indication information. In the solution of Embodiment 3, the uplink transmission resource and the downlink transmission resource do not overlap at all. Among them, not overlapping at all may mean: overlapping in time domain but not overlapping in frequency domain, not overlapping in time domain but overlapping in frequency domain, or not overlapping in both time domain and frequency domain. In other words, in the solution of Embodiment 3, the uplink transmission resource is only used for uplink transmission and not for downlink reception; the downlink transmission resource is only used for downlink reception and not for uplink transmission.

[0196] For more content about S81, reference can be made to the relevant description of S41 above, which will not be elaborated here.

[0197] S82, the network device sends conflict resource information to the first terminal device. The conflict resource indication information includes a direction indication field and a resource indication field. The direction indication field is used to indicate the first transmission direction, and the resource indication field is used to indicate the uplink resource position and / or the downlink resource position corresponding to at least one serving cell. Correspondingly, the first terminal device receives the conflict resource information.

[0198] For the specific content about S82, reference can be made to the relevant description of the conflict resource information above, which will not be elaborated here.

[0199] S83. If the first transmission direction includes the uplink and at least part of the position of the first uplink resource overlaps with the position of the uplink transmission resource, the first terminal device cancels the uplink transmission on all or part of the resources of the uplink transmission resource; if the first transmission direction includes the downlink and at least part of the position of the first downlink resource overlaps with the position of the downlink transmission resource, the downlink reception on all or part of the resources of the downlink transmission resource is cancelled.

[0202] Embodiment Four

[0203] Refer to Figure 9 , Figure 9 is a signaling interaction diagram of the fourth communication method in the embodiments of the present application. Figure 9 The method shown includes S91 and S92.

[0204] S91. The network device sends first reference indication information to the first terminal device, and the first reference indication information is used to indicate the time domain range and / or frequency domain range of the RR. Correspondingly, the first terminal device receives the first reference indication information.

[0205] Specifically, the RR occupies a certain frequency domain width in the frequency domain and a certain time domain width in the time domain. Further, the RR is divided into multiple sub-regions, and each sub-region is a part of the time-frequency resources in the RR. Specifically, the frequency domain range corresponding to each sub-region is a part of the frequency domain range corresponding to the reference region and / or the time domain range corresponding to each sub-region is a part of the time domain range corresponding to the reference region.

[0206] Specifically, the reference region is divided into M1 parts in the frequency domain direction of the RR, and the reference region is divided into M2 regions in the time domain direction. Among them, both M1 and M2 are positive integers, and the values of M1 and M2 can be defined by the protocol or can be configured by the network device.

[0207] In specific implementation, the RR indicated by the first reference indication information can correspond to at least one serving cell. Specifically, the RR indicated by the first reference indication information can include the resource positions corresponding to at least one serving cell, or the RR indicated by the first reference indication information can include the uplink resource positions and downlink resource positions corresponding to at least one serving cell. That is, the terminal devices in at least one serving cell can use the same RR to determine the positions of the time-frequency resources preempted by the burst service.

[0208] Alternatively, the RR indicated by the first reference indication information may correspond to the serving cell where the first terminal device is located. That is to say, the RR may be configured or indicated for each serving cell. The terminal device in each serving cell may use the RR corresponding to this serving cell to determine the location of the time-frequency resources preempted by the burst service.

[0209] Refer to Figure 10 , Figure 10 which is a schematic diagram of a reference region in an embodiment of this application. As Figure 10 shown, in the frequency domain direction, the RR is divided into 2 parts, and in the time domain direction, the RR is divided into 7 regions. Thus, the RR is divided into 14 sub-regions.

[0210] Refer to Figure 11 , Figure 11 which is a schematic diagram of another reference region in an embodiment of this application. As Figure 11 shown, in the time domain direction, the RR is divided into 14 regions and is not divided in the frequency domain direction. Thus, the RR is divided into 14 sub-regions.

[0211] Next, an exemplary description of the determination of the frequency domain range and time domain range of the RR is given.

[0212] Example a. The network device configures the time domain range of the RR through high-layer signaling, and the frequency domain range of the RR can be defined by the protocol.

[0213] Specifically, the network device may configure the listening opportunity of the conflict resource information in the high-layer signaling. The time domain range between two adjacent listening opportunities may be the time domain range of the RR. The listening opportunity of the conflict resource information may refer to the symbol position where the Physical Downlink Control Channel (PDCCH) carrying the second DCI is located.

[0214] Alternatively, the network device may indicate the time domain range of the RR through a time domain bitmap in the high-layer signaling, where each bit in the time domain bitmap corresponds to the same time domain width.

[0215] Alternatively, the network device may indicate the starting time domain position and time domain width of the time domain range of the RR, and thus the time domain range of the RR can be determined. For example, the high-layer signaling may include the starting slot index, starting symbol index, and time domain width information of the RR.

[0216] In addition, the frequency domain range of the RR may be the frequency domain range defined by the protocol that supports full duplex. For example, the protocol may pre-define the frequency domain range that supports in-band full duplex.

[0217] Example b. The network device configures the frequency domain range of the RR through high-layer signaling, and the time domain range of the RR is defined by the protocol.

[0218] Specifically, the network device may configure the start position and frequency domain width of the frequency domain range of the RR in the high-layer signaling. Alternatively, the network device may indicate the frequency domain range of the RR through a frequency domain bitmap in the high-layer signaling, where each bit in the frequency domain bitmap corresponds to the same frequency domain width. Alternatively, the network device may indicate the frequency domain range of the RR in the high-layer signaling in the form of a Resource Indicator Value (RIV). Thus, the first terminal device may determine the frequency domain range of the RR according to the high-layer signaling.

[0219] In addition, the time domain range of the RR may be the time domain range defined by the protocol that supports full duplex. For example, the protocol may pre-define the time domain range that supports in-band full duplex.

[0220] Example c. The network device configures the time domain range and the frequency domain range of the RR through high-layer signaling.

[0221] Specifically, the network device may configure the time domain range and the frequency domain range of the RR through the same high-layer signaling. Alternatively, the network device may configure the time domain range of the RR through one high-layer signaling, and configure the frequency domain range of the RR through another high-layer signaling. For the specific manner of the high-layer signaling to configure the time domain range of the RR and the specific manner of the high-layer signaling to configure the frequency domain range of the RR, reference may be made to the relevant descriptions above, which will not be elaborated here.

[0222] It should be noted that the high-layer signaling in this article may be radio resource control (RRC) signaling, but is not limited thereto.

[0223] S92. The first terminal device determines the first resource location according to the resource indication field and the reference area.

[0224] Combined with the solution of Embodiment 1, in the first implementation manner of S92, the first terminal device determines the first resource location according to the first target sub-domain and the RR. Among them, the frequency domain range of the RR is greater than or equal to the frequency domain range occupied by the first resource location, and the time domain range of the RR is greater than or equal to the time domain range occupied by the first resource location.

[0225] Specifically, the first target sub-domain may include K bits, and each bit corresponds to a sub-region in RR. Among them, K = M1 × M2. If the value of a certain bit among the K bits is "1", it indicates that the sub-region corresponding to this bit is the resource position preempted by the burst service. If the value of a certain bit among the K bits is "0", it indicates that the sub-region corresponding to this bit is not the resource position preempted by the burst service. Thus, the first terminal device can determine the first resource position according to the value of the first target sub-domain and RR.

[0226] Combined with the solution of Embodiment 2, in the second implementation manner of S92, the first terminal device determines the first uplink resource position and / or the first downlink resource position according to the first target sub-domain and RR. Among them, the frequency domain range of RR is greater than or equal to the frequency domain range occupied by the first uplink resource position and the first downlink resource position, and the time domain range of RR is greater than or equal to the time domain range occupied by the first uplink resource position and the first downlink resource position.

[0227] Specifically, the first uplink sub-domain in the first target sub-domain may include K1 bits, and each bit corresponds to a sub-region in RR. Among them, K1 = M1 × M2. If the value of a certain bit among the K1 bits is "1", it indicates that the sub-region corresponding to this bit is the resource position conflicting with the burst service. If the value of a certain bit among the K1 bits is "0", it indicates that the resource of the sub-region corresponding to this bit is not the resource position conflicting with the burst service. Thus, the first terminal device can determine the first uplink resource position according to the value of the first uplink sub-domain in the first target sub-domain and RR.

[0228] In addition, the first downlink sub-domain in the first target sub-domain may include K2 bits, and each bit corresponds to a sub-region in RR. Among them, K2 = M1 × M2. If the value of a certain bit among the K2 bits is "1", it indicates that the sub-region corresponding to this bit is the resource position preempted by the burst service. If the value of a certain bit among the K2 bits is "0", it indicates that the sub-region corresponding to this bit is not the resource position preempted by the burst service. Thus, the first terminal device can determine the first downlink resource position according to the value of the first downlink sub-domain in the first target sub-domain and RR.

[0229] Combined with the solution of Embodiment 2, in the third implementation manner of S92, the first terminal device determines the first uplink resource position according to the second target sub-domain and RR, and / or determines the first downlink resource position according to the third target sub-domain and RR. Among them, the frequency domain range of RR is greater than or equal to the frequency domain range occupied by the first uplink resource position and the first downlink resource position, and the time domain range of RR is greater than or equal to the time domain range occupied by the first uplink resource position and the first downlink resource position.

[0230] Specifically, the second target sub-domain may include K3 bits, and each bit corresponds to a sub-region in RR. Among them, K3 = M1 × M2. If a certain bit value in the K3 bits is "1", it indicates that the sub-region corresponding to this bit is a resource location conflicting with the burst service. If a certain bit value in the K3 bits is "0", it indicates that the sub-region corresponding to this bit is not a resource location conflicting with the burst service. Thus, the first terminal device can determine the first uplink resource location according to the value of the second target sub-domain and RR.

[0231] In addition, the third target sub-domain may include K4 bits, and each bit corresponds to a sub-region in RR. Among them, K4 = M1 × M2. If a certain bit value in the K4 bits is "1", it indicates that the sub-region corresponding to this bit is a resource location preempted by the burst service. If a certain bit value in the K4 bits is "0", it indicates that the sub-region corresponding to this bit is not a resource location preempted by the burst service. Thus, the first terminal device can determine the first downlink resource location according to the value of the third target sub-domain and RR.

[0232] As described above, in Embodiment 4, the network device configures RR for the first terminal device, so that the first terminal device can determine the first resource location according to RR and the resource indication domain, or determine the first uplink resource location and / or the first downlink resource location according to RR and the resource indication domain.

[0233] For more content about Embodiment 4, reference can be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0234] Embodiment 5

[0235] Refer to Figure 12 , Figure 12 which is a signaling interaction diagram of the fifth communication method in the embodiments of the present application. Figure 12 The method shown includes S121 and S122.

[0236] S121, the network device sends the second reference indication information and / or the third reference indication information to the first terminal device. The second reference indication information is used to indicate the time domain range and / or the frequency domain range of the reference uplink region, and the third reference indication information is used to indicate the time domain range and / or the frequency domain range of the reference downlink region. Correspondingly, the first terminal device receives the second reference indication information and / or the third reference indication information.

[0237] In a specific implementation, the second reference indication information and the third reference indication information may be carried in the same signaling. For example, they may be carried in the same signaling (such as an RRC signaling). Or, the second reference indication information and the third reference indication information may be carried in different signals. Exemplarily, the second reference indication information and the third reference indication information may be carried in different RRC signals.

[0238] It should be noted that the network device can send the second reference indication information and the third reference indication information simultaneously. For example, the second reference indication information and the third reference indication information can be carried in the same signaling. Alternatively, the network device can first send the second reference indication information and then send the third reference indication information; or the network device can first send the third reference indication information and then send the second reference indication information.

[0239] Specifically, if the network device only configures uplink transmission resources for the first terminal device and does not configure downlink transmission resources, in S121, the network device can send the second reference indication information to the first terminal device but does not send the third reference indication information. If the network device only configures downlink transmission resources for the first terminal device and does not configure uplink transmission resources, in S121, the network device can send the third reference indication information to the first terminal device but does not send the second reference indication information. If the network device configures both uplink transmission resources and downlink transmission resources for the first terminal device, in S121, the network device can send the second reference indication information and the third reference indication information to the first terminal device.

[0240] Among them, the RUR configured by the second reference indication information occupies a certain frequency domain width in the frequency domain and a certain time domain width in the time domain. Further, the RUR is divided into multiple sub-regions. The RDR configured by the third reference indication information occupies a certain frequency domain width in the frequency domain and a certain time domain width in the time domain. Further, the RDR is divided into multiple sub-regions.

[0241] Further, the first terminal device can determine the RUR and / or the RDR.

[0242] It should be noted that the specific content and determination method for determining the frequency domain range and / or time domain range of the RUR can refer to the relevant description above about determining the frequency domain range and / or time domain range of the RR, and will not be elaborated here.

[0243] S122, the first terminal device determines the first uplink resource position according to the resource indication field and the RUR, and / or determines the first downlink resource position according to the resource indication field and the RDR.

[0244] Among them, the frequency domain range of the RUR is greater than or equal to the frequency domain range occupied by the first uplink resource position, and the time domain range of the RUR is greater than or equal to the time domain range occupied by the first uplink resource position. Among them, the frequency domain range of the RDR is greater than or equal to the frequency domain range occupied by the first downlink resource position, and the time domain range of the RDR is greater than or equal to the time domain range occupied by the first downlink resource position.

[0245] In an implementation of S122, the first terminal device determines the first uplink resource location according to the first uplink sub-domain and RUR in the first target sub-domain, and / or the first terminal device determines the first downlink resource location according to the first downlink sub-domain and RDR in the first target sub-domain.

[0246] Specifically, RUR is divided into K1 sub-regions, and the first uplink sub-domain in the first target sub-domain may include K1 bits, and each bit corresponds to a sub-region in RUR. If a certain bit value in the K1 bits is "1", it means that the sub-region corresponding to this bit is the resource location conflicting with the burst service. If a certain bit value in the K1 bits is "0", it means that the sub-region corresponding to this bit is not the resource location conflicting with the burst service. Thus, the first terminal device can determine the first uplink resource location according to the value of the first uplink sub-domain in the first target sub-domain and RUR.

[0247] RDR is divided into K2 sub-regions, and the first downlink sub-domain in the first target sub-domain may include K2 bits, and each bit corresponds to a sub-region in RDR. If a certain bit value in the K2 bits is "1", it means that the sub-region corresponding to this bit is the resource location preempted by the burst service. If a certain bit value in the K2 bits is "0", it means that the sub-region corresponding to this bit is not the resource location preempted by the burst service. Thus, the first terminal device can determine the first downlink resource location according to the value of the first downlink sub-domain in the first target sub-domain and RDR.

[0248] In another implementation of S122, the first terminal device can determine the first uplink resource location according to the second target sub-domain and RUR, and / or the first terminal device can determine the first downlink resource location according to the third target sub-domain and RDR.

[0249] Specifically, RUR is divided into K3 sub-regions, and the second target sub-domain may include K3 bits, and each bit corresponds to a sub-region in RUR. If a certain bit value in the K3 bits is "1", it means that the sub-region corresponding to this bit is the resource location conflicting with the burst service. If a certain bit value in the K3 bits is "0", it means that the sub-region corresponding to this bit is not the resource location conflicting with the burst service. Thus, the first terminal device can determine the first uplink resource location according to the value of the second target sub-domain and RUR.

[0250] The RDR is divided into K4 sub-regions. The first downlink sub-region in the first target sub-domain may include K4 bits, and each bit corresponds to a sub-region in the RDR. If the value of a certain bit among the K4 bits is "1", it indicates that the sub-region corresponding to this bit is the resource location preempted by the burst service. If the value of a certain bit among the K4 bits is "0", it indicates that the sub-region corresponding to this bit is not the resource location preempted by the burst service. Thus, the first terminal device can determine the first downlink resource location according to the third target sub-domain and the RDR.

[0251] As described above, in the solution of Embodiment 5, the network device configures the RUR and / or RDR for the first terminal device, so that the first terminal device can determine the first uplink resource location according to the RUR and the resource indication field, and / or determine the first downlink resource location according to the RDR and the resource indication field.

[0252] For more content about Embodiment 5, reference can be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0253] Embodiment 6

[0254] Refer to Figure 13 , Figure 13 is a schematic flowchart of the sixth communication method in the embodiments of the present application. Figure 13 The method shown includes S131. Figure 13 The method shown can be executed by a terminal device. Specifically, Figure 13 The method shown can be executed by each terminal device having a resource conflict with the burst service.

[0255] S131, receive conflict resource information, where the conflict resource information is used to indicate the first transmission direction and the resource locations corresponding to at least one serving cell, and the first transmission direction includes uplink and / or downlink;

[0256] Wherein, if the resource locations corresponding to at least one serving cell and the transmission resources of the first transmission direction at least partially overlap, the transmission on part or all of the transmission resources of the first transmission direction is cancelled.

[0257] In a specific implementation, the conflict resource information may indicate the directions preempted by one or more burst services. Exemplarily, as described above, the directions preempted by multiple burst services may be the same. Or, the transmission directions preempted by multiple burst services may also be different, and the first transmission direction may include the transmission directions preempted by each burst service.

[0258] The conflict resource information may indicate the resource locations corresponding to at least one serving cell, where the resource locations corresponding to each serving cell may include the resource locations preempted by one or more burst services. Further, the resource locations preempted by multiple burst services on one serving cell may be the same or different.

[0259] In a specific implementation, the transmission time domain location of the conflict resource information may be before the earliest time domain location among the resource locations corresponding to at least one serving cell. That is, the conflict resource information may be transmitted before the time domain resource locations preempted by burst services. For example, the time interval between the transmission time domain location of the conflict resource information and the start time domain location of RR / RUR / RDR may be greater than or equal to the minimum processing time of the terminal device. Another example is that the time interval between the transmission time domain location of the conflict resource information and the start time domain location of RR / RUR / RDR may be the sum of the minimum processing time of the terminal device and an offset. Wherein, the offset may be configured by higher layer signaling. And the offset is greater than 0.

[0260] Alternatively, the transmission time domain location of the conflict resource information may be after the latest time domain location among the resource locations corresponding to at least one serving cell. That is, the conflict resource information may be transmitted after the time domain resource locations preempted by burst services. Exemplarily, the transmission time domain location of the conflict resource information may be in the same time slot as the time domain resource locations preempted by burst services, or the transmission time domain location of the conflict resource information may be in the next time slot after the time slot where the time domain resource locations preempted by burst services are located.

[0261] In an example, if the first transmission direction only includes the uplink and does not include the downlink, the transmission time domain location of the conflict resource information may be before the earliest time domain location among the resource locations corresponding to at least one serving cell. If the first transmission direction only includes the downlink and does not include the uplink, the transmission time domain location of the conflict resource information may be after the latest time domain location among the resource locations corresponding to at least one serving cell.

[0262] Further, for each terminal device that receives the conflict resource information, the terminal device may determine the resource locations preempted by burst services.

[0263] If the first transmission direction includes the uplink and at least part of the resources used by the terminal device for uplink transmission overlaps with the resource locations in conflict with burst services, the terminal device may cancel the uplink transmission on all or part of the resources in the resources used for uplink transmission. Among them, part of the resources in the resources used for uplink transmission refers to the resources in the overlapping area between the location of the resources used for uplink transmission and the resource locations in conflict with burst services.

[0264] If the first transmission direction includes downlink, and at least part of the resources used by the terminal device for downlink transmission overlaps with the resources preempted by the burst service, the terminal device may cancel the downlink reception on all or part of the resources in the resources used for downlink transmission. Among them, part of the resources in the resources used for downlink transmission refers to the resources in the overlapping area between the position of the resources used for downlink transmission and the position of the resources preempted by the burst service.

[0265] For more content about Embodiment 6, reference may be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0266] Embodiment 7

[0267] Refer to Figure 14 , Figure 14 FIG. is a signaling interaction diagram of the seventh communication method according to the embodiments of the present application. Figure 14 The method shown may include S141.

[0268] S141. The network device sends resource indication information to the first terminal device, and the resource indication information is used to indicate the first transmission resource for the first uplink data transmission and the transmission priority of the first uplink data. Correspondingly, the first terminal device receives the resource indication information.

[0269] For the convenience of distinction, the resource indication information in S141 may be denoted as the second resource indication information. Exemplarily, the second resource indication information may be carried in the third DCI.

[0270] Specifically, the first uplink data may be data carried by a Physical Uplink Shared Channel (PUSCH), that is, the first transmission resource may be the first PUSCH resource. Alternatively, it may also be data carried by a Physical Uplink Control Channel (PUCCH), or the first transmission resource may be the first PUCCH resource.

[0271] In addition, the second resource indication information may include priority indication information, and the priority indication information may be used to indicate the transmission priority of the first uplink data. Exemplarily, the third DCI may include a priority indication field, and the bit value in the priority indication field may be used to indicate the transmission priority of the first uplink data.

[0272] Exemplarily, the priority indication field may include 2 bits. Among them, if the value of the 2 bits is 00, it indicates that the transmission priority is 1; if the value of the 2 bits is 01, it indicates that the transmission priority is 2; if the value of the 2 bits is 10, it indicates that the transmission priority is 3; if the value of the 2 bits is 11, it indicates that the transmission priority is 4. In addition, before S141, the network device allocates a second transmission resource for the first terminal device for second uplink data transmission. Among them, the second uplink data may be data carried by PUSCH, that is, the second transmission resource may be a second PUSCH resource. Or, the second uplink data may also be data carried by PUCCH, or the second transmission resource may be a second PUCCH resource.

[0273] Among them, if at least part of the first transmission resource overlaps with the second transmission resource, and the transmission priority of the first uplink data is higher than that of the second uplink data, the first terminal device may cancel the transmission of the second uplink data on the second transmission resource. If the transmission priority of the first uplink data is lower than that of the second uplink data, the first terminal device may cancel the transmission of the first uplink data on the first transmission resource.

[0274] In other embodiments, the priority indication field may include 1 bit. If the bit value is 1, it indicates that the first uplink data is preferentially transmitted when the transmission resources of the first uplink data conflict with those of other uplink data. If the bit value is 0, it indicates that the transmission of the first uplink data is cancelled when the transmission resources of the first uplink data conflict with those of other uplink data.

[0275] In other embodiments, if the network device allocates multiple transmission resources for different uplink data to the first terminal device, and at least part of the multiple transmission resources overlaps, the first terminal device may compare the transmission priorities of each uplink data. Specifically, the transmission priority of the uplink data may be indicated by the priority indication field in the resource indication information of the transmission resource for the uplink data. Exemplarily, the larger the bit value in the priority indication field, the higher the transmission priority. Further, the first terminal device may send the uplink data with the highest transmission priority on the overlapping resources. Also exemplarily, if the bit value in the priority indication field is 0, it indicates that the transmission of the uplink data corresponding to the priority indication field is cancelled when the transmission resources of different uplink data conflict, and if the bit value in the priority indication field is 1, it indicates that the transmission of the uplink data corresponding to the priority indication field is reserved when the transmission resources of different uplink data conflict. Further, the first terminal device may send the uplink data with a transmission priority of 1 on the overlapping resources.

[0276] As described above, Embodiment 7 provides a solution mechanism for conflicts among multiple services of the same terminal device. In the solution of Embodiment 7, a priority indication is introduced into the resource indication information for allocating transmission resources, so as to indicate to the terminal device to perform the transmission with the highest priority when there are multiple service conflicts.

[0277] For more content about Embodiment 7, reference can be made to the relevant descriptions of other embodiments in this article, which will not be elaborated here.

[0278] Embodiment 8

[0279] The NR system supports the transmission of eMBB services and uRLLC services in a time division multiplexing (TDM) or frequency division multiplexing (FDM) manner. To meet the latency requirements, the uRLLC services burst by a terminal device can preempt some of the resources occupied by the eMBB services that other terminal devices are already transmitting, thereby interrupting the transmission of the eMBB services of these preempted UEs on some resources. The network device indicates the preempted time-frequency resources in the RDR to the terminal device of the preempted resources through DCI2-1. Currently, the frequency domain range of the RDR refers to the activated downlink partial bandwidth (BWP).

[0280] In Release 18 of the Third Generation Partnership Project (3GPP), the duplex enhancement issue will study the subband full duplex (SBFD) for network devices. On the network device side, taking advantage of the existence of subbands, the uplink and downlink transmissions are divided in the frequency domain, and the uplink and downlink can be transmitted simultaneously at the same moment. By using frequency division, interference is reduced and the complexity of the network device is lowered. That is, subband full duplex divides the frequency domain resources into uplink subbands and downlink subbands on the network device side, and downlink transmission and uplink reception can be respectively performed simultaneously on different subbands. Among them, the uplink subband is the frequency domain resource for uplink transmission, and the downlink subband is the frequency domain resource for downlink transmission. For the terminal device, half duplex is still supported, and it can only perform downlink reception on the downlink subband or uplink transmission on the uplink subband at a certain time point.

[0281] In the SBFD scenario, the activated downlink BWP may include uplink subbands, and since the URLLC downlink services do not preempt the frequency domain resources in the uplink subbands. Therefore, in the SBFD scenario, the existing downlink preemption indication needs to be improved.

[0282] Refer to Figure 15 , Figure 15It is a signaling interaction schematic diagram of the eighth communication method in the embodiments of this application. Figure 15 The method shown may include S151.

[0283] S151. The network device sends preemption indication information to the terminal device. The preemption indication information is used to indicate the preempted time-frequency resources. Among them, the preempted time-frequency resources are located within the downlink reference region, and the downlink reference region is the resources in the activated downlink BWP excluding the uplink subbands configured for downlink symbols and flexible symbols in the frequency domain. Correspondingly, the terminal device receives the preemption indication information.

[0284] Specifically, both the activated downlink BWP and the downlink subbands are located on the carrier of the serving cell.

[0285] The RDR may include at least one of the following in the time domain: uplink symbol, downlink symbol, and flexible symbol. In subband full duplex, an uplink subband may be configured on the downlink symbol, so that the network device can perform uplink reception in the uplink subband on the downlink symbol to increase the resources for uplink transmission and reduce the delay. Among them, the flexible symbol can be used as an uplink symbol or a downlink symbol based on the configuration of the network device, and an uplink subband and / or a downlink subband may be configured on the flexible symbol. In other embodiments, a downlink subband may be configured on the uplink symbol, so that the network device can perform downlink transmission in the downlink subband on the uplink symbol.

[0286] In the solution of this embodiment, the frequency domain range of the RDR is the frequency domain resources in the activated downlink BWP excluding the uplink subbands configured on the downlink symbols and / or the uplink subbands configured on the flexible symbols.

[0287] Specifically, if the time domain range of the RDR includes downlink symbols, the frequency domain range of the RDR may be the frequency domain resources in the activated downlink BWP excluding the uplink subbands configured on the downlink symbols. That is, if the time domain range of the RDR includes downlink symbols and an uplink subband is configured on the downlink symbol, then the uplink subband on the downlink symbol needs to be excluded.

[0288] If the time domain range of the RDR includes flexible symbols, the frequency domain range of the RDR may be the frequency domain resources in the activated downlink BWP excluding the uplink subbands configured on the flexible symbols. That is, if the time domain range of the RDR includes flexible symbols and an uplink subband is configured on the flexible symbol, then the uplink subband on the flexible symbol needs to be excluded.

[0289] In one example, the RDR is the overlapping resources between the activated downlink BWP and the downlink subbands in the frequency domain.

[0290] Refer to Figure 16 ,Figure 16 It is a schematic diagram of the frequency domain range of a downlink reference region in an embodiment of the present application.

[0291] As Figure 16 shown, the time domain range of the RDR is time slot n. Among them, symbol 2 and symbol 3 in time slot n are downlink symbols, and symbol 4 is a flexible symbol. Therefore, the RDR is the frequency domain resource in the activated downlink BWP except for the uplink subbands on symbols 2, 3, and 4. That is to say, the uplink subbands on symbols 2, 3, and 4 are the resources that need to be excluded. The RDR is the overlapping resource between the activated downlink BWP and the downlink subband in the frequency domain.

[0292] In the solution of Embodiment 7, the activated downlink BWP can be divided into Q parts, and the RDR can be divided into P parts in the time domain. Thus, P×Q sub-regions can be obtained. Among them, both P and Q are positive integers. Further, each preemption indication information may include P×Q bits, and each bit corresponds to one sub-region among the P×Q sub-regions. For the terminal device, the invalid sub-regions can be ignored. Among them, the invalid sub-region refers to the sub-region that corresponds to the downlink symbol and the flexible symbol in the time domain and corresponds to the uplink subband in the frequency domain. Further, for the other sub-regions except the invalid sub-regions among the P×Q sub-regions, if the corresponding bit value is "1", it means that the resources in this sub-region are preempted by the burst service, and if the corresponding bit value is "0", it means that the resources in this sub-region are not preempted by the burst service. Thus, the terminal device can determine the preempted downlink time-frequency resources according to the preemption indication information.

[0294] Embodiment 9

[0295] As described above, the NR system supports the transmission of eMBB services and uRLLC services in the TDM or FDM mode. To meet the latency requirements, the uRLLC service burst by a terminal device can preempt the resources of the eMBB service of other terminal devices, and the terminal device whose resources are preempted cancels the uplink transmission of the eMBB service. The network device can indicate the preempted time-frequency resources in the RUR to the terminal device whose resources are preempted through DCI2-4. Currently, the time domain range of the RUR does not include the downlink symbol.

[0296] As described above, in subband full duplex, the uplink subband can be configured on the downlink symbol, so that the network device can perform uplink reception in the uplink subband on the downlink symbol. Among them, the flexible symbol can be used as an uplink symbol or a downlink symbol based on the configuration of the network device, and the uplink subband and / or downlink subband can be configured on the flexible symbol.

[0297] Therefore, the URLLC uplink service may preempt the downlink symbols and / or flexible symbols configured with uplink subbands. If the downlink symbols or flexible symbols configured with uplink subbands are excluded in the RUR, the uplink cancellation indication cannot accurately indicate the preempted uplink time-frequency resources. Therefore, in the SBFD scenario, the existing uplink cancellation indication needs to be improved.

[0298] Referring to Figure 17 , Figure 17 FIG. Figure 17 The signaling interaction diagram of the eighth communication method according to the embodiment of the present application is shown.

[0299] S171, the network device sends cancellation indication information to the terminal device. The cancellation indication information is used to indicate the cancelled time-frequency resources. The cancelled time-frequency resources are located in the reference uplink region, and the reference uplink region includes downlink symbols and / or flexible symbols configured with uplink subbands in the time domain. Correspondingly, the terminal device receives the cancellation indication information.

[0300] In the solution of this embodiment, if uplink subbands are configured on the downlink symbols and / or flexible symbols within the time domain range of the RUR, the resources in the uplink subbands configured on the downlink symbols and / or flexible symbols may be preempted by burst services.

[0301] For this reason, in the solution of this embodiment, the time domain range of the RUR includes downlink symbols configured with uplink subbands. In other words, the downlink symbols not configured with uplink subbands are excluded, but the downlink symbols configured with uplink subbands are not excluded. In addition, the flexible symbols not configured with uplink subbands are excluded, but the flexible symbols configured with uplink subbands are not excluded.

[0302] In a specific implementation, the cancellation indication information may be carried in the DCI. For example, it may be carried in DCI2-4.

[0303] Exemplarily, the RUR depends at least on T CI , T CI represents the number of symbols that can be excluded from the symbols for receiving the synchronization signal (SS) / Physical Broadcast Channel (PBCH) block and the downlink symbols not configured with uplink subbands among multiple symbols. Among them, if the configured listening period is greater than one time slot or the listening period is 1 time slot and there is only a listening opportunity, the time domain range of the RUR is the length of the listening period, otherwise the time domain range of the RUR is configured by higher layer signaling, for example, configured by timeDurationforCI.

[0304] In other embodiments, in sub-band full duplex, a downlink sub-band may be configured on an uplink symbol, so that a network device can perform downlink transmission on the downlink sub-band of the uplink symbol.
