In some embodiments of the present application, the terminal equipment may also be a device with a transceiver function, such as a chip system. Among them, the chip system may include a chip and may also include other discrete devices.

[0086] In the embodiments of the present application, a network device may refer to a device that provides wireless communication functionality for a terminal device. The network device may be referred to as an access network device, such as a radio access network (RAN) device or an access network element. 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) (also referred to as a base station device), a base transceiver station (BTS), a node B (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 an evolved node B (ng-eNB), wherein the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both the gNB and the ng-eNB can be connected to the 5G core network. In wireless local area networks (WLANs), the device that provides base station functions is an access point (AP).

[0088] It should be understood that the term "and / or" used in the embodiments of this application merely describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " used herein indicates that the associated objects are in an "or" relationship.

[0089] The term "at least one" used in the embodiments of the present application refers to one or more.

[0090] The term "plurality" used in the embodiments of the present application refers to two or more.

[0091] The first, second, etc. descriptions appearing in the embodiments of this application are only for illustration and distinction of the description objects. There is no order, nor does it indicate any special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application.

[0092] As described in the background, future communication systems may introduce simultaneous, same-frequency, full-duplex communication technology to improve the utilization efficiency of time-frequency resources. Specifically, network devices and / or terminal devices can perform uplink and downlink transmissions on the same time-frequency resource. This time-frequency resource that supports uplink and downlink transmission is referred to as a simultaneous, same-frequency, full-duplex resource (hereinafter referred to as a "full-duplex resource").

[0093] In actual applications, a network device may allocate a full-duplex resource (referred to as resource 1 for ease of distinction) to a terminal device for both uplink and downlink transmission. Alternatively, the network device may allocate resource 1 to multiple terminal devices for both uplink and downlink transmission. For example, the network device may allocate resource 1 to terminal device 1 for uplink transmission and resource 1 to terminal device 2 for downlink transmission.

[0094] Assume that after allocating resource 1 to terminal device 1 and / or terminal device 2, the network device allocates resource 2 to the burst service of terminal device 3. If resource 1 and resource 2 conflict, the network device needs to indicate the resource conflict to the terminal device occupying resource 1.

[0095] In view of this, an embodiment of the present application provides a communication method in which a network device indicates to a terminal device, through conflicting resource information, the resource location corresponding to a first transmission direction and at least one serving cell. The first transmission direction includes uplink and / or downlink. If the resource location indicated by the conflicting resource information and the location of the transmission resources for the first transmission direction configured by the network device for the terminal device at least partially overlap, the terminal device cancels transmission on some or all of the transmission resources for the first transmission direction. This can resolve resource conflicts between different terminal devices.

[0096] The following is a detailed description of the specific embodiments of this application in conjunction with the accompanying drawings. It should be noted that the actions performed by the network device in this application can be performed by the network device, the device in the network device (such as a processor, chip), the chip, etc., and the actions performed by the terminal device can be performed by the terminal device, the device in the terminal device (such as a processor, chip), the chip, etc., and this application does not limit this. For the convenience of description, the embodiments provided in this application are described using the execution subjects as network devices and terminal devices as examples.

[0097] Example 1

[0098] 1 , which is a schematic diagram of signaling interaction of a first communication method according to an embodiment of the present application, includes S11 , S12 , and S13 .

[0099] S11: The network device sends resource indication information to the first terminal device. 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 referred to as first resource indication information.

[0100] Specifically, the network device may allocate data transmission resources to the first terminal device for uplink transmission and downlink reception, wherein the data transmission resources may be full-duplex resources.

[0101] In a specific implementation, resource indication information can be carried in the first Downlink Control Information (DCI). That is, the network device can indicate a block of full-duplex resources through a DCI, thereby indicating uplink transmission resources and downlink transmission resources to the first terminal device. In other words, uplink time-frequency domain resource allocation and downlink time-frequency domain resource allocation are completed through a DCI.

[0102] S12: The network device sends conflicting resource information to the first terminal device. The conflicting 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 location corresponding to at least one serving cell. In response, the first terminal device receives the conflicting resource information.

[0103] In a specific implementation, the conflicting resource information may be carried in the second DCI.

[0104] It should be noted that the "conflict resource information" in the embodiments of the present application can also be referred to as "resource failure information", "resource preemption information", "resource unavailable information", "resource cancellation information", "resource occupation information", "failure indication information", "preemption indication information", "cancellation indication information", "conflict indication information", "occupancy indication information", etc. This article does not limit the name of the conflict resource information.

[0105] Specifically, the "resource location" in this article refers to the location of the time-frequency resources occupied by the burst service. It should be noted that the burst service is the service of other terminal devices other than the first terminal device. More specifically, the "resource location" in this article may refer to the location of the time-frequency resources occupied by the burst service in the reference region (RR). For the relevant description of RR, please refer to the specific description of Example 4 below, which will not be repeated here. Furthermore, the "resource location corresponding to the service cell" refers to the location of the time-frequency resources occupied by the burst service in the service cell. Among them, a service cell may include one carrier, or a service cell may include multiple carriers. The "resource location corresponding to the service cell" in this article can also be replaced by "resource location corresponding to the carrier".

[0106] In this article, "the position of the time-frequency resources occupied by the burst service" can be replaced by "the position of the time-frequency resources that conflict with the burst service", or replaced by "the position of the time-frequency resources that overlap with the burst service", etc.

[0107] In one example, when the transmission direction occupied by the burst service is uplink, the "position of the time-frequency resources occupied by the burst service" can be replaced by the "position of the time-frequency resources that conflict with the burst service". When the transmission direction occupied by the burst service is uplink and downlink, the "resource position corresponding to the service cell" can also be replaced by the "position of the time-frequency resources overlapping with the burst service". In addition, in this document, the "position of the time-frequency resources occupied by the burst service" can be simply referred to as the "resource position occupied by the burst service", and accordingly, the "position of the time-frequency resources that conflict with the burst service" can be simply referred to as the "resource position that conflicts with the burst service", and the "position of the time-frequency resources overlapping with the burst service" can be simply referred to as the "resource position overlapping with the burst service".

[0108] Furthermore, the first transmission direction refers to the transmission direction preempted by the burst service. If the first transmission direction is uplink, it means that the uplink transmission on the time-frequency resources that conflict with the burst service will be completely or partially canceled. If the first transmission direction is downlink, it means that the downlink transmission on the time-frequency resources preempted by the burst service will be completely or partially canceled. If the first transmission direction is uplink and downlink, it means that the uplink transmission on the time-frequency resources that conflict with the burst service will be completely or partially canceled, and the downlink transmission on the time-frequency resources preempted by the burst service will be completely or partially canceled.

[0109] It should be noted that this embodiment does not limit the number of burst services.

[0110] In one case, the number of burst services is 1, and the transmission direction occupied by the burst service is uplink or downlink.

[0111] In another case, the number of burst services is 1, and the transmission directions occupied by the burst service are uplink and downlink.

[0112] In another case, there are multiple burst services, and the transmission directions occupied by the multiple burst services are the same. The first transmission direction refers to the transmission direction occupied by the multiple burst services.

[0113] 2 , which is a schematic diagram of a first type of second DCI according to an embodiment of the present application, as shown in FIG2 , the second DCI 20 includes a direction indication field and a resource indication field 21 .

[0114] The direction indication field may include multiple bits to indicate the first transmission direction.

[0115] Exemplarily, the direction indication field may include 2 bits, and the value of the 2 bits is used to indicate the first transmission direction.

[0116] In one example, one of the two bits corresponds to the uplink and the other corresponds to the downlink. For example, the first bit of the two bits corresponds to the downlink, and the second bit of the two bits corresponds to the uplink. If the value of the bit corresponding to the uplink is 1, it indicates that the first transmission direction includes the uplink. If the value of the bit corresponding to the downlink is 1, it indicates that the first transmission direction includes the downlink.

[0117] In another example, if the value of the two bits is 00, it indicates that the first transmission direction is downlink, if the value of the two bits is 01, it indicates that the first transmission direction is uplink, and if the value of the two bits is 10, it indicates that the first transmission direction is uplink and downlink.

[0118] Thus, the first terminal device can determine the first transmission direction based on the direction indication field.

[0119] Furthermore, the resource indication field 21 may include at least one first sub-field, wherein each first sub-field corresponds to a serving cell, and each first sub-field is used to indicate the resource location corresponding to a serving cell. As shown in FIG2 , the resource indication field 21 may include N first sub-fields, where N is a positive integer. Thus, the resource indication field 21 may be used to indicate the resource locations corresponding to N serving cells.

[0120] The first terminal device can determine the first subdomain corresponding to the serving cell where the first terminal device is located from the resource indication domain, and then further determine the resource location corresponding to the serving cell where the first terminal device is located. For ease of description, the first subdomain corresponding to the serving cell where the first terminal device is located is hereinafter referred to as the first target subdomain, and the resource location corresponding to the serving cell where the first terminal device is located is referred to as the first resource location.

[0121] The first terminal device may only decode the first target sub-domain to determine the first resource location. The first terminal device may not need to decode other first sub-domains other than the first target sub-domain.

[0122] 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 based on the value of the K bits in the first target sub-domain and the RR configured by the network device. For the specific content of how the first terminal device can determine the first resource location based on the value of the first target sub-domain and the RR configured by the network device, please refer to the relevant description of Example 4 below, which will not be repeated here.

[0123] S13: If the first resource location and the data transmission resource location at least partially overlap, the first terminal device cancels transmission on part or all of the transmission resources in the first transmission direction.

[0124] Here, "at least partially overlap" may include both complete overlap and partial overlap.

[0125] If the first resource location at least partially overlaps with the location of the data transmission resource, and the first transmission direction is uplink, the first terminal device cancels the uplink transmission in the data transmission resource. In addition, the first terminal device can still perform downlink reception on the data transmission resource.

[0126] Here, "canceling uplink transmission in the data transmission resources" may mean that uplink transmission on all resources in the data transmission resources is canceled. Alternatively, "canceling uplink transmission in the data transmission resources" may mean that uplink transmission on some resources in the data transmission resources is canceled. When uplink transmission on some resources is canceled, uplink transmission on other resources in the data transmission resources, except for resources in the overlapping area, remains retained. Here, some resources may refer to resources in the overlapping area between the location of the data transmission resources and the location of the first resource.

[0127] If the first resource location at least partially overlaps with the location of the data transmission resource, and the first transmission direction is downlink, the first terminal device cancels downlink reception in the data transmission resource. In addition, the first terminal device can still perform uplink transmission on the data transmission resource.

[0128] Here, "canceling downlink reception in the data transmission resources" may mean that downlink reception on all resources in the data transmission resources is canceled. Alternatively, "canceling downlink reception in the 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 resources in the overlapping area, remains. The "some resources" may refer to resources in the overlapping area between the location of the data transmission resources and the location of the first resource.

[0129] If the first resource position at least partially overlaps with the position of the data transmission resource, and the first transmission direction is uplink and downlink, the first terminal device can cancel the uplink transmission in the data transmission resource and cancel the downlink reception in the data transmission resource.

[0130] 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.

[0131] In the second example, the first terminal device may cancel uplink transmission on part of the data transmission resources and cancel downlink reception on part of the data transmission resources. In addition, uplink transmission and downlink reception on other resources except part of the data transmission resources are retained.

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

[0133] In the fourth example, the first terminal device may cancel uplink transmission on part of the data transmission resources and cancel downlink reception on all of the data transmission resources. In addition, uplink transmission on other resources except part of the data transmission resources is retained.

[0134] Refer to FIG. 3 , which is a schematic diagram of a resource conflict in an embodiment of the present application.

[0135] As shown in Figure 3, a portion of the location of data transmission resource 31 overlaps with first resource location 32, wherein the overlapping portion is an overlapping region 33. Exemplarily, if the first transmission direction is uplink, uplink transmission in data transmission resource 31 is canceled. If the first transmission direction is downlink, uplink transmission in data transmission resource 31 is retained, downlink reception in overlapping region 33 is canceled, and downlink reception on resources other than those in overlapping region 33 in data transmission resource 31 is retained. If the first transmission direction is both uplink and downlink, uplink transmission in data transmission resource 31 is canceled, downlink transmission in resources in overlapping region 33 is canceled, but downlink transmission on resources other than those in overlapping region 33 in data transmission resource 31 is retained.

[0136] The solution of the first embodiment is described below with reference to specific examples.

[0137] Example 1: The data transmission resources indicated by the network device are used for the enhanced mobile broadband (eMBB) uplink service and eMBB downlink service of the first terminal device, and the burst service is the ultra-reliable low latency communication (URLLC) downlink service.

[0138] In one case, the transmission direction preempted by the URLLC downlink service is downlink, that is, the first transmission direction is downlink.

[0139] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, the transmission of the eMBB downlink service on the resources in the data transmission resource preempted by the URLLC downlink service is canceled, and the transmission of the eMBB uplink service in the data transmission resource is completely retained. 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 the eMBB uplink service data on the data transmission resource.

[0140] In another case, considering that URLLC services have a higher priority, eMBB uplink services may interfere with the reception of URLLC downlink services. Therefore, the URLLC downlink services preempt transmission directions of uplink and downlink. That is, the first transmission direction is uplink and downlink.

[0141] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmission of the eMBB uplink service in the data transmission resource is canceled, and the transmission of the eMBB downlink service on the resources in the data transmission resource preempted by the URLLC downlink service is canceled. That is, the first terminal device cancels the transmission of eMBB uplink service data on the data transmission resource and ignores eMBB downlink service data received on resources in the overlapping area between the location of the data transmission resource and the first resource location.

[0142] Example 2: The data transmission resources indicated by the network device are used for the eMBB uplink service and URLLC downlink service of the first terminal device, and the burst service is the URLLC uplink service.

[0143] In the solution of Example 2, the transmission direction for URLLC uplink service preemption is uplink. That is, the first transmission direction is uplink. In S13, if the location of the data transmission resource and the location of the first resource at least partially overlap, all transmission of the eMBB uplink service in the data transmission resource is canceled. That is, the first terminal device cancels sending eMBB uplink service data on the data transmission resource.

[0144] Example 3: The data transmission resources indicated by the network device are used for the eMBB downlink service and URLLC uplink service of the first terminal device, and the burst service is the URLLC downlink service.

[0145] In one case, the transmission direction preempted by the URLLC downlink service is downlink, that is, the first transmission direction is downlink.

[0146] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, the transmission of the eMBB downlink service on the resources in the data transmission resource that are preempted by the URLLC downlink service is canceled, and the transmission of the URLLC uplink service in the data transmission resource is retained. 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 the URLLC uplink service data on the data transmission resource.

[0147] In another case, considering that the priority of the URLLC downlink service may be greater than the priority of the URLLC uplink service, the URLLC uplink service may interfere with the reception of the URLLC downlink service. Therefore, the transmission direction preempted by the URLLC downlink service is uplink and downlink. That is, the first transmission direction is uplink and downlink.

[0148] In S13, if the location of the data transmission resource and the first resource location at least partially overlap, all transmission of the URLLC uplink service in the data transmission resource is canceled, and the transmission of the eMBB downlink service on the resources in the data transmission resource preempted by the URLLC downlink service is canceled. That is, the first terminal device cancels the transmission of the 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.

[0149] Example 4: The data transmission resources indicated by the network device are 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.

[0150] 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 transmission of the eMBB uplink service in the data transmission resource is canceled, and the transmission of the eMBB downlink service on the data transmission resource resources preempted by the burst service is also canceled. That is, the first terminal device cancels the transmission of eMBB uplink service data on the data transmission resource and ignores eMBB downlink service data received on resources in the area where the data transmission resource location overlaps with the first resource location.

[0151] From the above, in the solution of embodiment 1, the network device allocates data transmission resources for uplink transmission and downlink reception to the first terminal device. If the resource position occupied by the burst service of other terminal devices conflicts with the data transmission resources, the network device sends conflict resource information to the first terminal device. The first terminal device can determine the direction occupied by the burst service and the resource position occupied 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 at the occupied resource position in the data transmission resource, or in other words, the first terminal device ignores the data received at the occupied resource position, 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 resources to avoid collisions between uplink transmissions of different services.

[0152] For more details about the first embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0153] Example 2

[0154] 4, which is a schematic diagram of signaling interaction of the second communication method in an embodiment of the present application, includes S41, S42, and S43.

[0155] 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 downlink resource indication information.

[0156] Specifically, the network device may allocate uplink transmission resources to the first terminal device for uplink transmission through uplink resource indication information, and / or, the network device may allocate downlink transmission resources to the first terminal device for downlink reception through downlink resource indication information.

[0157] 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). Alternatively, the uplink resource indication information and the downlink resource indication information can be carried in different signaling. 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 can be 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 at the same time; alternatively, the network device can also send the uplink resource indication information first, and then send the downlink resource indication information; alternatively, the network device can send the downlink resource indication information first, and then send the uplink resource indication information.

[0158] Referring to Figure 5, which is a schematic diagram of resource allocation in an embodiment of the present application, as shown in Figure 5, uplink transmission resources 51 and downlink transmission resources 52 may at least partially overlap.

[0159] 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. Alternatively, 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. Alternatively, the uplink transmission resource 51 and the downlink transmission resource 52 can be allocated to the first terminal device.

[0160] Continuing to refer to Figure 4, S42, the network device sends conflicting resource information to the first terminal device. The conflicting 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 downlink resource position corresponding to at least one service cell.

[0161] The "uplink resource location corresponding to the serving cell" refers to the location of the uplink time-frequency resources in the serving cell that are occupied by the burst service. Alternatively, the "uplink resource location corresponding to the serving cell" may refer to the location of the uplink time-frequency resources in the serving cell that conflict with the burst service. 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 document may also be replaced with "uplink resource location corresponding to the carrier."

[0162] The "downlink resource location corresponding to the serving cell" refers to the location of downlink time-frequency resources within the serving cell that are occupied by burst traffic. In this document, "downlink resource location corresponding to the serving cell" can also be replaced with "downlink resource location corresponding to the carrier."

[0163] The uplink resource position refers to the position of the uplink time-frequency resources that conflict with the burst service, and the downlink resource position refers to the position of the downlink time-frequency resources that are preempted by the burst service. More specifically, the "uplink resource position" in this article may refer to the position of the time-frequency resources that conflict with the burst service within the RR, or it may refer to the position of the time-frequency resources that conflict with the burst service within the reference uplink region (RUR). The "downlink resource position" in this article may refer to the position of the time-frequency resources that are preempted by the burst service within the RR, or it may refer to the position of the time-frequency resources that are preempted by the burst service within the reference downlink region (RDR). For the relevant description of RR, please refer to the specific description of Example 4 below, and for the relevant description of RUR and RDR, please refer to the specific description of Example 5 below, which will not be repeated here.

[0164] In this article, the "location of time-frequency resources occupied by sudden services" can be simply referred to as the "resource location occupied by sudden services", and accordingly, the "location of time-frequency resources that conflict with sudden services" can be simply referred to as the "resource location that conflicts with sudden services".

[0165] Refer to Figure 6, which is a schematic diagram of the second type of second DCI in an embodiment of the present application.

[0166] As shown in Figure 6, the second DCI 60 includes a direction indication field and a resource indication field 61. The resource indication field 61 includes N first subfields 611, where N is a positive integer. Each first subfield 611 corresponds to a serving cell and is used to indicate the resource location corresponding to a serving cell. Furthermore, each first subfield 611 may include a first uplink subfield and / or a first downlink subfield. The resource location indicated by the first uplink subfield is an uplink resource location, and the resource location indicated by the first downlink subfield is a downlink resource location.

[0167] Specifically, the first uplink sub-field may include K1 bit values, and the first downlink sub-field 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 the protocol or may be configured by the network device. The value of K2 may be defined by the protocol or may be configured by the network device. In one example, K1 = K2.

[0168] Furthermore, the first terminal device may determine the first target subdomain from the resource indication domain.

[0169] 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.

[0170] Specifically, the first terminal device can determine the uplink resource position corresponding to the serving cell where it is located based on 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 referred to as the first uplink resource position below. Assuming that the second first sub-domain in Figure 6 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.

[0171] Furthermore, if the first transmission direction is uplink, that is, if the burst service only preempts 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 include only the first uplink subfield and not the first downlink subfield. This can reduce the length of the conflicting resource information and help save signaling overhead.

[0172] 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.

[0173] Specifically, the first terminal device can determine the downlink resource position corresponding to the serving cell where it is located based on the value of the first downlink sub-domain in the first target sub-domain. For ease of description, the downlink resource position corresponding to the serving cell where the first terminal device is located is referred to as the first downlink resource position below. Assuming that the second first sub-domain in Figure 6 is the first target sub-domain and the first transmission direction is downlink, the first terminal device can only decode the first downlink sub-domain 2 to determine the first downlink resource position.

[0174] Furthermore, if the first transmission direction is downlink, that is, the burst service preempts only the downlink, the network device can set the value of the first uplink subfield in each first subfield to 0. Alternatively, if the first transmission direction is downlink, each first subfield in the conflicting resource information can include only the first downlink subfield and not the first uplink subfield. This can reduce the length of the conflicting resource information and help save signaling overhead.

[0175] If the direction indication field indicates that the first transmission direction is uplink and downlink, the first terminal device can decode the first uplink subfield and the first downlink subfield in the first target subfield. The first terminal device can determine the first uplink resource position based on the value of the first uplink subfield in the first target subfield, and determine the first downlink resource position based on the value of the first downlink subfield in the first target subfield.

[0176] Regarding the specific content of how the first terminal device can determine the first uplink resource position based on the value of the first uplink sub-domain, and regarding the specific content of how the first downlink resource position can be determined based on the value of the first downlink sub-domain, please refer to the relevant descriptions of Example 4 and Example 5 below and will not be repeated here.

[0177] Refer to Figure 7, which is a schematic diagram of the third type of second DCI in an embodiment of the present application.

[0178] As shown in Figure 7, the second DCI 70 includes a direction indication field and a resource indication field 71. The resource indication field 71 includes a second uplink subfield and a second downlink subfield. The second uplink subfield is used to indicate the uplink resource location corresponding to at least one serving cell, and the second downlink subfield is used to indicate the downlink resource location corresponding to at least one serving cell.

[0179] Among them, the second uplink sub-domain includes N second sub-domains, N is a positive integer, and each second sub-domain is used to indicate the uplink resource position corresponding to a serving cell. The second downlink sub-domain includes N third sub-domains, and each third sub-domain is used to indicate the downlink resource position corresponding to a serving cell.

[0180] Specifically, the second subfield may include a K3 bit value, and the third subfield may include a K4 bit value, where K3 is a positive integer and K4 is a positive integer. The value of K3 may be defined by the protocol or may be configured by the network device. The value of K4 may be defined by the protocol or may be configured by the network device. In one example, K3 = K4.

[0181] If the direction indication domain indicates that the first transmission direction is uplink, the first terminal device can determine the second subdomain corresponding to the service cell where it is located from the second uplink subdomain. For the convenience of description, the second subdomain corresponding to the service cell where the first terminal device is located is recorded as the second target subdomain below. Furthermore, the first terminal device can decode the second target subdomain and determine the first uplink resource position according to the value of the second target subdomain. The first terminal device does not need to decode other second subdomains in the second uplink subdomain except the second target subdomain, nor does it need to decode the second downlink subdomain. Assuming that the second subdomain 2 in Figure 7 is the second target subdomain, the first terminal device can only decode the second subdomain 2.

[0182] Furthermore, if the first transmission direction is uplink, that is, if the burst service only preempts the uplink, the network device can set the value of the second downlink subfield to 0. Alternatively, if the first transmission direction is uplink, the resource indication field in the conflicting resource information can include only the second uplink subfield and not the second downlink subfield. This can reduce the length of the conflicting resource information and help save signaling overhead.

[0183] If the direction indication domain indicates that the first transmission direction is downlink, the first terminal device can determine the third subdomain corresponding to the service cell where it is located from the second downlink subdomain. For the convenience of description, the third subdomain corresponding to the service cell where the first terminal device is located is referred to as the third target subdomain below. Furthermore, the first terminal device can determine the first downlink resource position based on decoding the third target subdomain and according to the value of the third target subdomain. The first terminal device does not need to decode other third subdomains in the second downlink subdomain except the third target subdomain, nor does it need to decode the second uplink subdomain. Assuming that the third subdomain 2 in Figure 7 is the third target subdomain, the first terminal device can only decode the third subdomain 2.

[0184] Furthermore, if the first transmission direction is downlink, that is, the burst service preempts only the downlink, the network device can set the value of the second uplink subfield to 0. Alternatively, if the first transmission direction is uplink, the resource indication field in the conflicting resource information can include only the second downlink subfield and not the second uplink subfield. This can reduce the length of the conflicting resource information and help save signaling overhead.

[0185] If the direction indication field indicates that the first transmission direction is uplink and downlink, the first terminal device can determine the second target subfield from the second uplink subfield and determine the third target subfield from the second downlink subfield. Further, the first terminal device decodes the second target subfield and the third target subfield, and determines the first uplink resource location based on the value of the second target subfield and determines the first downlink resource location based on the value of the third target subfield.

[0186] Regarding the specific content of how the first terminal device can determine the first uplink resource position based on the value of the second target subdomain, and regarding the specific content of how the first downlink resource position can be determined based on the value of the third target subdomain, please refer to the relevant descriptions of Example 4 and Example 5 below and will not be repeated here.

[0187] 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 uplink transmission resources is canceled; 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 downlink transmission resources is canceled.

[0188] 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 uplink transmission in the uplink transmission resource. Furthermore, if the first transmission direction does not include downlink, and the uplink transmission resource and the downlink transmission resource at least partially overlap, downlink reception on the resources in the overlapping area of ​​the uplink transmission resource and the downlink transmission resource may still be retained.

[0189] Here, "canceling uplink transmission in the uplink transmission resources" may mean that uplink transmission on all resources in the uplink transmission resources is canceled. Alternatively, "canceling uplink transmission in the uplink transmission resources" may mean that uplink transmission on some resources in the uplink transmission resources is canceled. When uplink transmission on some resources is canceled, uplink transmission on other resources in the uplink transmission resources other than the some resources remains. The some resources may refer to resources in an overlapping area between the location of the uplink transmission resources and the location of the first uplink resource.

[0190] If the first resource location at least partially overlaps with the location of the downlink transmission resource, and the first transmission direction includes downlink, the first terminal device may cancel 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, uplink transmission on the resources in the overlapping area of ​​the uplink transmission resource and the downlink transmission resource may still be retained.

[0191] Here, "canceling downlink reception in the downlink transmission resources" may mean that downlink reception on all resources in the downlink transmission resources is canceled. Alternatively, "canceling downlink reception in the downlink transmission resources" may mean that downlink reception on some resources in the downlink transmission resources is canceled. When downlink reception on some resources is canceled, downlink reception on other resources in the downlink transmission resources other than the some resources remains. The some resources may refer to resources in an overlapping area between the location of the downlink transmission resources and the location of the first downlink resource.

[0194] 8, which is a schematic diagram of signaling interaction of a third communication method in an embodiment of the present application, includes S81, S82, and S83.

[0195] 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 downlink resource indication information.

[0196] Specifically, the network device may allocate uplink transmission resources to the first terminal device for uplink transmission through uplink resource indication information, and / or, the network device may allocate downlink transmission resources to the first terminal device for downlink reception through downlink resource indication information. In the scheme of embodiment three, the uplink transmission resources and the downlink transmission resources are completely non-overlapping. Herein, completely non-overlapping may mean: overlapping in the time domain but not in the frequency domain, non-overlapping in the time domain but not in the frequency domain, or non-overlapping in both the time domain and the frequency domain. In other words, in the scheme of embodiment three, uplink transmission resources are only used for uplink transmission, not for downlink reception; downlink transmission resources are only used for downlink reception, not for uplink transmission.

[0197] For more information about S81, please refer to the above description of S41, which will not be repeated here.

[0198] S82: The network device sends conflicting resource information to the first terminal device. The conflicting resource indication information includes a direction indication field and a resource indication field. The direction indication field is used to indicate a first transmission direction, and the resource indication field is used to indicate an uplink resource location and / or a downlink resource location corresponding to at least one serving cell. Accordingly, the first terminal device receives the conflicting resource information.

[0204] 9, which is a schematic diagram of signaling interaction in a fourth communication method according to an embodiment of the present application, includes S91 and S92.

[0205] S91: The network device sends first reference indication information to the first terminal device, where 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.

[0206] Specifically, RR occupies a certain frequency domain width in the frequency domain and a certain time domain width in the time domain. Furthermore, RR is divided into multiple sub-areas, each sub-area being a portion of the time-frequency resources in RR. Specifically, the frequency domain range corresponding to each sub-area is a portion of the frequency domain range corresponding to the reference area and / or the time domain range corresponding to each sub-area is a portion of the time domain range corresponding to the reference area.

[0207] Specifically, the RR reference region is divided into M1 parts in the frequency domain and M2 parts in the time domain. M1 and M2 are both positive integers, and their values ​​can be defined by the protocol or configured by the network device.

[0208] In a specific implementation, the RR indicated by the first reference indication information may correspond to at least one serving cell. Specifically, the RR indicated by the first reference indication information may include a resource location corresponding to at least one serving cell, or the RR indicated by the first reference indication information may include an uplink resource location and a downlink resource location corresponding to at least one serving cell. In other words, the terminal equipment within at least one serving cell may use the same RR to determine the location of the time-frequency resources occupied by the burst service.

[0209] Alternatively, the RR indicated by the first reference indication information may correspond to the serving cell where the first terminal device is located. In other words, the RR may be configured or indicated for each serving cell. The terminal device in each serving cell may use the RR corresponding to the serving cell to determine the location of the time-frequency resources occupied by the burst service.

[0210] Referring to Figure 10, which is a schematic diagram of a reference region in an embodiment of the present application, as shown in Figure 10, in the frequency domain, RR is divided into two parts, and in the time domain, RR is divided into seven regions, thus, RR is divided into 14 sub-regions.

[0211] Referring to Figure 11, Figure 11 is a schematic diagram of another reference region in an embodiment of the present application. As shown in Figure 11, the RR is divided into 14 regions in the time domain direction and is not divided in the frequency domain direction. Thus, the RR is divided into 14 sub-regions.

[0212] The following is an exemplary description of how to determine the frequency domain range and time domain range of RR.

[0213] Example a. The network device configures the time domain range of RR through high-layer signaling, and the frequency domain range of RR can be defined by the protocol.

[0214] Specifically, the network device may configure the monitoring timing of the conflicting resource information in the high-layer signaling, and the time domain range between two adjacent monitoring timings may be the time domain range of the RR. The monitoring timing of the conflicting resource information may refer to the symbol position of the physical downlink control channel (PDCCH) carrying the second DCI.

[0215] Alternatively, the network device may indicate the time domain range of the RR through a time domain bitmap in higher layer signaling, wherein each bit in the time domain bitmap corresponds to the same time domain width.

[0216] Alternatively, the network device may indicate the starting time domain position and time domain width of the RR time domain range in high-layer signaling, thereby determining the time domain range of the RR. For example, the high-layer signaling may include the starting time slot index, starting symbol index, and time domain width information of the RR.

[0217] In addition, the frequency domain range of the RR may be a frequency domain range that supports full-duplex as defined by the protocol. For example, the protocol may predefine a frequency domain range that supports full-duplex in-band.

[0218] Example b. The network device configures the frequency domain range of RR through high-layer signaling, and the time domain range of RR is defined by the protocol.

[0219] Specifically, the network device can configure the starting position and frequency domain width of the frequency domain range of RR in the high-level signaling. Alternatively, the network device can indicate the frequency domain range of RR through a frequency domain bit map in the high-level signaling, wherein each bit in the frequency domain bit map corresponds to the same frequency domain width. Alternatively, the network device can indicate the frequency domain range of RR by means of a resource indicator value (RIV) in the high-level signaling. Thus, the first terminal device can determine the frequency domain range of RR based on the high-level signaling.

[0220] In addition, the time domain range of the RR may be a time domain range that supports full-duplex as defined by the protocol. For example, the protocol may predefine a time domain range that supports full-duplex in-band.

[0221] Example c. The network device configures the time domain range and the frequency domain range of RR through high-layer signaling.

[0222] Specifically, the network device can configure the time domain range of RR and the frequency domain range of RR through the same high-layer signaling. Alternatively, the network device can configure the time domain range of RR through one high-layer signaling and configure the frequency domain range of RR through another high-layer signaling. Regarding the specific manner in which the time domain range of RR is configured by high-layer signaling and the specific manner in which the time domain range of RR is configured by high-layer signaling, reference can be made to the relevant description above and will not be repeated here.

[0223] It should be noted that the high-layer signaling in this article may be radio resource control (RRC) signaling, but is not limited thereto.

[0224] S92. The first terminal device determines the first resource location according to the resource indication domain and the reference area.

[0225] In combination with the solution of Example 1, in a first implementation of S92, the first terminal device determines the first resource location based on the first target subdomain and the RR. 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.

[0226] Specifically, the first target subdomain may include K bits, each bit corresponding to a sub-area in the RR. K = M1 × M2. If the value of a bit among the K bits is "1," it indicates that the sub-area corresponding to the bit is a resource location occupied by a burst service. If the value of a bit among the K bits is "0," it indicates that the sub-area corresponding to the bit is not a resource location occupied by a burst service. Thus, the first terminal device can determine the first resource location based on the value of the first target subdomain and the RR.

[0227] In combination with the solution of Example 2, in the second implementation of S92, the first terminal device determines the first uplink resource position and / or the first downlink resource position based on the first target subdomain and RR. Wherein, 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.

[0228] Specifically, the first uplink subdomain in the first target subdomain may include K1 bits, and each bit corresponds to a sub-area in the RR. Wherein, K1 = M1 × M2. If the value of a bit in the K1 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location that conflicts with the burst service. If the value of a bit in the K1 bits is "0", it indicates that the resource of the sub-area corresponding to the bit is not a resource location that conflicts with the burst service. Thus, the first terminal device can determine the first uplink resource location based on the value of the first uplink subdomain in the first target subdomain and the RR.

[0229] In addition, the first downlink subdomain in the first target subdomain may include K2 bits, each bit corresponding to a sub-area in the RR. Wherein, K2 = M1 × M2. If the value of a bit in the K2 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location occupied by a burst service. If the value of a bit in the K2 bits is "0", it indicates that the sub-area corresponding to the bit is not a resource location occupied by a burst service. Thus, the first terminal device can determine the first downlink resource location based on the value of the first downlink subdomain in the first target subdomain and the RR.

[0230] In combination with the solution of Example 2, in the third implementation of S92, the first terminal device determines the first uplink resource position based on the second target subdomain and RR, and / or determines the first downlink resource position based on the third target subdomain and RR. Wherein, 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.

[0231] Specifically, the second target subdomain may include K3 bits, each bit corresponding to a sub-area in the RR. Wherein, K3 = M1 × M2. If the value of a bit in the K3 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location that conflicts with the burst service; if the value of a bit in the K3 bits is "0", it indicates that the sub-area corresponding to the bit is not a resource location that conflicts with the burst service. Thus, the first terminal device can determine the first uplink resource location based on the value of the second target subdomain and the RR.

[0232] In addition, the third target subdomain may include K4 bits, each bit corresponding to a sub-area in the RR. K4 = M1 × M2. If the value of a bit in the K4 bits is "1," it indicates that the sub-area corresponding to the bit is a resource location occupied by a burst service. If the value of a bit in the K4 bits is "0," it indicates that the sub-area corresponding to the bit is not a resource location occupied by a burst service. Thus, the first terminal device can determine the first downlink resource location based on the value of the third target subdomain and the RR.

[0233] From the above, in embodiment four, the network device configures RR for the first terminal device, so that the first terminal device can determine the first resource location based on RR and the resource indication field, or determine the first uplink resource location and / or the first downlink resource location based on RR and the resource indication field.

[0234] For more details about the fourth embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0235] Example 5

[0236] 12, which is a schematic diagram of signaling interaction of the fifth communication method according to an embodiment of the present application, includes S121 and S122.

[0237] S121: The network device sends second reference indication information and / or third reference indication information to the first terminal device, where the second reference indication information is used to indicate the time domain range and / or frequency domain range of the reference uplink area, and the third reference indication information is used to indicate the time domain range and / or frequency domain range of the reference downlink area. Correspondingly, the first terminal device receives the second reference indication information and / or the third reference indication information.

[0238] 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 RRC signaling). Alternatively, the second reference indication information and the third reference indication information may be carried in different signaling. Exemplarily, the second reference indication information and the third reference indication information may be carried in different RRC signaling.

[0239] It should be noted that the network device may 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 may be carried in the same signaling. Alternatively, the network device may first send the second reference indication information and then send the third reference indication information; or alternatively, the network device may first send the third reference indication information and then send the second reference indication information.

[0240] 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 may send the second reference indication information to the first terminal device, but 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 may send the third reference indication information to the first terminal device, but 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 may send the second reference indication information and the third reference indication information to the first terminal device.

[0241] 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. Furthermore, the RUR is divided into multiple sub-areas. 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. Furthermore, the RDR is divided into multiple sub-areas.

[0242] Furthermore, the first terminal device may determine the RUR and / or the RDR.

[0243] It should be noted that the specific content and determination method of determining the frequency domain range and / or time domain range of RUR can refer to the above description of determining the frequency domain range and / or time domain range of RR, which will not be repeated here.

[0244] S122, the first terminal device determines the first uplink resource location according to the resource indication field and the RUR, and / or determines the downlink resource location according to the resource indication field and the RDR.

[0245] 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. 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.

[0246] In one embodiment of S122, the first terminal device determines the first uplink resource location based on the first uplink subdomain and RUR in the first target subdomain, and / or the first terminal device determines the first downlink resource location based on the first downlink subdomain and RDR in the first target subdomain.

[0247] Specifically, the RUR is divided into K1 sub-areas, and the first uplink sub-area in the first target sub-area may include K1 bits, each bit corresponding to a sub-area in the RUR. If the value of a bit in the K1 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location that conflicts with the burst service. If the value of a bit in the K1 bits is "0", it indicates that the sub-area corresponding to the bit is not a resource location that conflicts with the burst service. Therefore, the first terminal device can determine the first uplink resource location based on the value of the first uplink sub-area in the first target sub-area and the RUR.

[0248] The RDR is divided into K2 sub-areas, and the first downlink sub-area in the first target sub-area may include K2 bits, each bit corresponding to a sub-area in the RDR. If the value of a bit in the K2 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location occupied by a burst service. If the value of a bit in the K2 bits is "0", it indicates that the sub-area corresponding to the bit is not a resource location occupied by a burst service. Therefore, the first terminal device can determine the first downlink resource location based on the value of the first downlink sub-area in the first target sub-area and the RDR.

[0249] In another implementation of S122, the first terminal device may determine the first uplink resource location based on the second target subdomain and RUR, and / or the first terminal device may determine the first downlink resource location based on the third target subdomain and RDR.

[0250] Specifically, the RUR is divided into K3 sub-areas, and the second target sub-area may include K3 bits, each bit corresponding to a sub-area in the RUR. If the value of a bit in the K3 bits is "1", it indicates that the sub-area corresponding to the bit is a resource location that conflicts with the burst service. If the value of a bit in the K3 bits is "0", it indicates that the sub-area corresponding to the bit is not a resource location that conflicts with the burst service. Therefore, the first terminal device can determine the first uplink resource location based on the value of the second target sub-area and the RUR.

[0251] The RDR is divided into K4 sub-regions. The first downlink sub-region in the first target sub-region can include K4 bits, each bit corresponding to a sub-region in the RDR. If the value of a bit in the K4 bits is "1", it indicates that the sub-region corresponding to the bit is a resource location occupied by a burst service. If the value of a bit in the K4 bits is "0", it indicates that the sub-region corresponding to the bit is not a resource location occupied by a burst service. Therefore, the first terminal device can determine the first downlink resource location based on the third target sub-region and the RDR.

[0252] From the above, in the scheme of Example 5, the network device configures RUR and / or RDR for the first terminal device, so that the first terminal device can determine the first uplink resource position according to RUR and the resource indication field, and / or determine the first downlink resource position according to RDR and the resource indication field.

[0253] For more details about the fifth embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0254] Example 6

[0255] Referring to Figure 13, Figure 13 is a schematic flow chart of a sixth communication method according to an embodiment of the present application. The method shown in Figure 13 includes S131. The method shown in Figure 13 can be executed by a terminal device. Specifically, the method shown in Figure 13 can be executed by each terminal device that has a resource conflict with a burst service.

[0256] S131, receiving conflicting resource information, where the conflicting resource information is used to indicate a first transmission direction and a resource location corresponding to at least one serving cell, where the first transmission direction includes uplink and / or downlink;

[0257] If the resource location corresponding to at least one serving cell and the location of 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 canceled.

[0258] In a specific implementation, the conflicting resource information may indicate the direction of one or more burst services being preempted. For example, as described above, the directions of the multiple burst services being preempted may be the same. Alternatively, the transmission directions of the multiple burst services being preempted may be different, and the first transmission direction may include the transmission directions of each burst service being preempted.

[0259] The conflicting resource information may indicate a resource location corresponding to at least one serving cell, wherein the resource location corresponding to each serving cell may include a resource location occupied by one or more burst services. Furthermore, the resource locations occupied by multiple burst services on a serving cell may be the same or different.

[0260] In a specific implementation, the time domain position for sending the conflicting resource information may be located before the earliest time domain position in the resource position corresponding to at least one serving cell. That is, the conflicting resource information may be sent before the time domain resource position that is preempted by the burst service. For example, the time interval between the time domain position for sending the conflicting resource information and the starting time domain position of RR / RUR / RDR may be greater than or equal to the minimum processing time of the terminal device. For another example, the time interval between the time domain position for sending the conflicting resource information and the starting time domain position of RR / RUR / RDR may be the sum of the minimum processing time of the terminal device and the offset. The offset may be configured by high-level signaling. The offset is greater than 0.

[0261] Alternatively, the time domain location for sending the conflicting resource information may be located after the latest time domain location among the resource locations corresponding to at least one serving cell. That is, the conflicting resource information may be sent after the time domain resource location occupied by the burst service. Exemplarily, the time domain location for sending the conflicting resource information may be located in the same time slot as the time domain resource location occupied by the burst service, or the time domain location for sending the conflicting resource information may be located in the time slot immediately following the time slot containing the time domain resource location occupied by the burst service.

[0262] In one example, if the first transmission direction includes only uplink and does not include downlink, the time domain position for sending the conflicting resource information may be located before the earliest time domain position among the resource positions corresponding to the at least one serving cell. If the first transmission direction includes only downlink and does not include uplink, the time domain position for sending the conflicting resource information may be located after the latest time domain position among the resource positions corresponding to the at least one serving cell.

[0263] Furthermore, for each terminal device that receives conflicting resource information, the terminal device can determine the location of the resource occupied by the burst service.

[0264] If the first transmission direction includes uplink, and the resources used by the terminal device for uplink transmission at least partially overlap with the location of the resources that conflict with the burst service, the terminal device may cancel uplink transmission on all or part of the resources used for uplink transmission. The "partial resources" in the resources used for uplink transmission refer to resources in the overlapping area between the location of the resources used for uplink transmission and the location of the resources that conflict with the burst service.

[0265] If the first transmission direction includes downlink, and the resources used by the terminal device for downlink transmission at least partially overlap with the locations of the resources occupied by the burst service, the terminal device may cancel downlink reception on all or part of the resources used for downlink transmission. The "partial resources used for downlink transmission" refers to the resources in the overlapping area between the locations of the resources used for downlink transmission and the locations of the resources occupied by the burst service.

[0266] For more details about the sixth embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0267] Example 7

[0268] Referring to Figure 14, which is a schematic diagram of signaling interaction of a seventh communication method according to an embodiment of the present application, the method shown in Figure 14 may include S141.

[0269] S141: The network device sends resource indication information to the first terminal device, where the resource indication information is used to indicate a first transmission resource for first uplink data transmission and a transmission priority of the first uplink data. Correspondingly, the first terminal device receives the resource indication information.

[0270] For easy distinction, the resource indication information in S141 may be recorded as the second resource indication information. Exemplarily, the second resource indication information may be carried in the third DCI.

[0271] Specifically, the first uplink data may be data carried by a physical uplink shared channel (PUSCH), that is, the first transmission resource may be a first PUSCH resource. Alternatively, the first uplink data may be data carried by a physical uplink control channel (PUCCH), or the first transmission resource may be a first PUCCH resource.

[0272] In addition, the second resource indication information may include priority indication information, which 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.

[0273] Exemplarily, the priority indication field may include 2 bits, wherein the value of the 2 bits is 00, indicating that the transmission priority is 1; the value of the 2 bits is 01, indicating that the transmission priority is 2; the value of the 2 bits is 10, indicating that the transmission priority is 3; the value of the 2 bits is 11, indicating that the transmission priority is 4. In addition, the network device allocates a second transmission resource for the second uplink data transmission to the first terminal device before S141. The second uplink data may be data carried by PUSCH, that is, the second transmission resource may be a second PUSCH resource. Alternatively, the second uplink data may also be data carried by PUCCH, or the second transmission resource may be a second PUCCH resource.

[0274] Wherein, if the first transmission resource and the second transmission resource at least partially overlap, and the transmission priority of the first uplink data is higher than the transmission priority 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 the transmission priority of the second uplink data, the first terminal device may cancel the transmission of the first uplink data on the first transmission resource.

[0275] In other embodiments, the priority indication field may include one bit. If the bit value is 1, it indicates that when the transmission resource of the first uplink data conflicts with the transmission resource of other uplink data, the first uplink data is transmitted first. If the bit value is 0, it indicates that when the transmission resource of the first uplink data conflicts with the transmission resource of other uplink data, the transmission of the first uplink data is canceled.

[0276] In other embodiments, if the network device allocates multiple transmission resources for different uplink data to the first terminal device, and the multiple transmission resources at least partially overlap, the first terminal device can compare the transmission priorities of each uplink data. Specifically, the transmission priority of the uplink data can 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 can send uplink data with the highest transmission priority on overlapping resources. As another example, if the bit value in the priority indication field is 0, it means that the transmission of the uplink data corresponding to the priority indication field will be canceled when the transmission resources of different uplink data conflict, and if the bit value in the priority indication field is 1, it means that the transmission of the uplink data corresponding to the priority indication field will be retained when the transmission resources of different uplink data conflict. Further, the first terminal device can send uplink data with a transmission priority of 1 on overlapping resources.

[0277] From the above, Example 7 provides a mechanism for resolving conflicts between multiple services of the same terminal device. In the solution of Example 7, a priority indication is introduced in the resource indication information used to allocate transmission resources to indicate to the terminal device that the highest priority transmission should be performed when multiple services conflict.

[0278] For more details about the seventh embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0279] Example 8

[0280] The NR system supports the transmission of eMBB services and uRLLC services using time division multiplexing (TDM) or frequency division multiplexing (FDM). To meet latency requirements, a sudden uRLLC service from a terminal device can preempt some of the resources occupied by eMBB services already being transmitted by other terminal devices, thereby interrupting the transmission of eMBB services of these preempted UEs on some resources. The network device indicates the preempted time and frequency resources in the RDR to the terminal device whose resources are preempted through DCI2-1. Currently, the frequency domain range of the RDR refers to the activated downlink bandwidth (BWP).

[0281] In Release 18 (Rel-18) of the Third Generation Partnership Project (3GPP), the duplex enhancement topic will study subband full duplex (SBFD) for network equipment. On the network equipment side, the existence of subbands is used to divide uplink and downlink transmissions in the frequency domain, enabling simultaneous uplink and downlink transmission at the same time, reducing interference by using frequency division, and reducing the complexity of network equipment. In other words, subband full duplex divides the frequency domain resources into uplink subbands and downlink subbands on the network equipment side, and downlink transmission and uplink reception can be performed simultaneously on different subbands. Among them, the uplink subband is the frequency domain resource used for uplink transmission, and the downlink subband is the frequency domain resource used for downlink transmission. For terminal devices, half-duplex is still supported, and at a certain point in time, downlink reception can only be performed on the downlink subband or uplink transmission can be performed on the uplink subband.

[0282] In SBFD scenarios, the activated downlink BWP may include uplink subbands. Since URLLC downlink services do not preempt frequency domain resources in uplink subbands, the existing downlink preemption indication in SBFD scenarios needs to be improved.

[0283] 15, which is a schematic diagram of signaling interaction in an eighth communication method according to an embodiment of the present application, the method shown in FIG15 may include S151.

[0284] S151: The network device sends preemption indication information to the first terminal device. The preemption indication information is used to indicate the preempted time-frequency resources, where the preempted time-frequency resources are located within a downlink reference region, which in the frequency domain is the resources in the activated downlink BWP excluding the uplink subband configured for downlink symbols and flexible symbols. Correspondingly, the first terminal device receives the preemption indication information.

[0285] Specifically, the activated downlink BWP and downlink subband are both located on the carrier of the serving cell.

[0286] RDR may include at least one of the following in the time domain: an uplink symbol, a downlink symbol, and a flexible symbol. In sub-band full-duplex, an uplink sub-band may be configured on the downlink symbol, so that the network device can perform uplink reception in the uplink sub-band on the downlink symbol, thereby increasing the resources for uplink transmission and reducing latency. Specifically, the flexible symbol may be used as an uplink symbol or a downlink symbol based on the configuration of the network device, and the flexible symbol may be configured with an uplink sub-band and / or a downlink sub-band. In other embodiments, the uplink symbol may be configured with a downlink sub-band, so that the network device can perform downlink transmission in the downlink sub-band on the uplink symbol.

[0287] In the solution of this embodiment, the frequency domain range of the RDR is to activate frequency domain resources in the downlink BWP except for the uplink subband configured on the downlink symbols and / or the uplink subband configured on the flexible symbols.

[0288] Specifically, if the RDR time domain range includes downlink symbols, the RDR frequency domain range can be the frequency domain resources in the activated downlink BWP except for the uplink subband configured for the downlink symbols. In other words, if the RDR time domain range includes downlink symbols and the downlink symbols are configured with uplink subbands, the uplink subbands on the downlink symbols need to be excluded.

[0289] If the RDR time domain range includes flexible symbols, the RDR frequency domain range can be the frequency domain resources in the activated downlink BWP except for the uplink subband configured on the flexible symbols. In other words, if the RDR time domain range includes flexible symbols and uplink subbands are configured on the flexible symbols, the uplink subbands on the flexible symbols need to be excluded.

[0290] In one example, RDR activates overlapping resources between a downlink BWP and a downlink subband in the frequency domain.

[0291] Refer to Figure 16, which is a schematic diagram of the frequency domain range of a downlink reference area in an embodiment of the present application.

[0292] As shown in Figure 16, the time domain scope of RDR is time slot n, where symbols 2 and 3 in time slot n are downlink symbols, and symbol 4 is a flexible symbol. Therefore, in the frequency domain, RDR activates the frequency domain resources in the downlink BWP except for the uplink subbands in symbols 2, 3, and 4. In other words, the uplink subbands in symbols 2, 3, and 4 are resources that need to be excluded. In the frequency domain, RDR activates the overlapping resources between the downlink BWP and the downlink subbands.

[0293] In the scheme of embodiment seven, the activated downlink BWP can be divided into Q parts, and the RDR can be divided into P parts in the time domain, thereby obtaining P×Q sub-areas. Wherein, P and Q are both positive integers. Further, each preemption indication information may include P×Q bits, and each bit corresponds to one of the P×Q sub-areas. For the terminal device, the invalid sub-area can be ignored. Wherein, the invalid sub-area refers to the sub-area corresponding to the downlink symbol and the flexible symbol in the time domain and the uplink sub-band in the frequency domain. Further, for the other sub-areas in the P×Q sub-areas except the invalid sub-area, if the corresponding bit value is "1", it indicates that the resources in the sub-area are preempted by the burst service, and if the corresponding bit value is "0", it indicates that the resources in the sub-area are not preempted by the burst service. Thus, the terminal device can determine the preempted downlink time-frequency resources based on the preemption indication information.

[0295] Embodiment 9

[0296] As mentioned above, the NR system supports the transmission of eMBB and uRLLC services using TDM or FDM. To meet latency requirements, a sudden uRLLC service on one terminal device can preempt the eMBB service resources of other terminals. The terminal whose resources are preempted will cancel the uplink transmission of the eMBB service. The network equipment can indicate the preempted time and frequency resources within the RUR to the terminal whose resources are preempted via DCI2-4. Currently, the time domain range of the RUR does not include downlink symbols.

[0297] As described above, in sub-band full-duplex mode, downlink symbols can be configured with uplink sub-bands, allowing network devices to perform uplink reception in the uplink sub-bands of downlink symbols. Flexible symbols can be used as uplink or downlink symbols based on the network device's configuration, and can be configured with uplink and / or downlink sub-bands.

[0298] Therefore, URLLC uplink services may preempt downlink symbols and / or flexible symbols configured with uplink subbands. If downlink symbols or flexible symbols configured with uplink subbands are excluded from the RUR, the uplink cancellation indication cannot accurately indicate the preempted uplink time-frequency resources. Therefore, in SBFD scenarios, the existing uplink cancellation indication needs to be improved.

[0299] Referring to Figure 17, which is a schematic diagram of signaling interaction of an eighth communication method according to an embodiment of the present application, the method shown in Figure 17 may include S171.

[0300] S171: The network device sends cancellation indication information to the terminal device. The cancellation indication information indicates the time-frequency resources to be cancelled. The cancelled time-frequency resources are located in a reference uplink region. The reference uplink region includes downlink symbols and / or flexible symbols configured with uplink subbands in the time domain. In response, the terminal device receives the cancellation indication information.

[0301] In the solution of this embodiment, if uplink subbands are configured on downlink symbols and / or flexible symbols within the time domain range of the RUR, resources in the uplink subbands configured on the downlink symbols and / or flexible symbols may be preempted by burst services.

[0302] To this end, in the solution of this embodiment, the time domain range of the RUR includes downlink symbols assigned uplink subbands. In other words, downlink symbols not assigned uplink subbands are excluded, but downlink symbols assigned uplink subbands are not excluded. Furthermore, flexible symbols not assigned uplink subbands are excluded, but flexible symbols assigned uplink subbands are not excluded.

[0303] In a specific implementation, the cancellation indication information may be carried in DCI, for example, in DCI2-4.

[0304] For example, RUR depends on at least T CI , T CI Indicates the number of symbols that can be excluded from multiple symbols after symbols used to receive synchronization signal (SS) / Physical Broadcast Channel (PBCH) blocks and downlink symbols not configured with uplink subbands. If the configured listening period is greater than one slot or the listening period is one slot and only contains listening opportunities, 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, via timeDurationforCI.

[0305] In other embodiments, in sub-band full-duplex, a downlink sub-band may be configured on an uplink symbol, so that the network device can perform downlink transmission on the downlink sub-band on the uplink symbol.
