These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at" or "when" or "in response to determining".

[0067] The embodiment of the present disclosure provides a communication system. The communication system may be a communication system using cellular mobile communication technology. Figure 1 is a schematic diagram of the structure of a communication system in an embodiment of the present disclosure, see Figure 1 As shown, the communication system 10 may include: a terminal device 11 and a network device 12 .

[0068] In one embodiment, the terminal device 11 may be a device that provides voice or data connectivity to a user. In some embodiments, the terminal device may also be referred to as user equipment (UE), mobile station, subscriber unit, station or terminal equipment (TE), etc. The terminal device may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station or a tablet computer, etc. With the development of wireless communication technology, devices that can access a communication system, communicate with the network side of a communication system, or communicate with other devices through a communication system are all terminal devices in the embodiments of the present disclosure. For example, terminals and cars in intelligent transportation, household appliances in smart homes, power meter reading instruments in smart grids, voltage monitoring instruments, environmental monitoring instruments, video monitoring instruments in intelligent complete networks, cash registers, etc. In the embodiments of the present disclosure, the terminal device may communicate with a network device, and multiple terminal devices may also communicate with each other. Terminal devices can be static or mobile.

[0069] The network device 12 may be a device on the access network side for supporting the terminal to access the communication system. For example, it may be an evolved NodeB (eNB) in a 4G access technology communication system, a next generation nodeB (gNB) in a 5G access technology communication system, a transmission reception point (TRP), a relay node, an access point (AP), etc.

[0070] In the full-duplex enhancement project of the 3rd generation partnership project (3GPP), since transmission and reception are realized simultaneously on one carrier, the transmitter and receiver need to be able to better suppress cross-slot interference and self-interference. For cross-slot interference, it can be measured, avoided and eliminated through certain mechanisms. As for self-interference, the equipment needs to have a high degree of isolation between transmission and reception, so as to achieve a strong self-interference suppression capability. Generally speaking, although full-duplex can bring benefits such as increased throughput, reduced transmission delay (especially uplink transmission), and enhanced uplink coverage. However, in order to minimize the impact on the complexity and radio frequency of terminal equipment, only network equipment supports full-duplex, while terminal equipment still only supports half-duplex.

[0071] Exemplarily, the full-duplex mode of a network device may include the following three situations:

[0072] The first type is non-overlapping subband, that is, uplink information and downlink information are transmitted on different subbands, and there is no overlap between them in the frequency domain;

[0073] The second type is partial overlapping subband, that is, uplink information and downlink information are transmitted on different subbands, and there is partial overlap between subbands in the frequency domain;

[0074] The third type is shared spectrum full duplex, that is, uplink information and downlink information can be transmitted on completely overlapping frequency domain resources.

[0075] It can be seen that when the network device supports full-duplex, the uplink subband (UL subband) for transmitting uplink information and the downlink subband (DL subband) for transmitting downlink information can be flexibly configured. Then, in view of this situation, how the terminal device correctly receives the control signaling is an urgent problem to be solved.

[0076] In the disclosed embodiment, the configuration of the control area (such as the control resource set (CORESET)) used to transmit control signaling is configured from the network device to the terminal device through high-level signaling, which may include the following information: CORESET ID, frequency domain configuration information of CORESET and other related information.

[0077] Exemplarily, the above-mentioned high-layer signaling may include: radio resource control (RRC) signaling, broadcast message, system message, medium access control (MAC) control element (CE), signaling carried by DCI or PDSCH, etc.

[0078] In order to solve the above problems, an embodiment of the present disclosure provides a communication method, which can be applied to the terminal device described in one or more of the above embodiments, such as UE.

[0079] It should be noted that, in the embodiments of the present disclosure, CORESET is an example of a control area, and the above communication method is described with this example. In the following embodiments, both the first control resource set and the second control resource set can be understood as CORESET.

[0080] Figure 2 FIG. 1 is a schematic diagram of an implementation flow of a communication method on the terminal device side in the embodiment of the present disclosure, see Figure 2 As shown, the method may include:

[0081] S201, the terminal device determines, according to the instruction of the network device, that the first frequency domain resources used for transmitting part or all of the CORESET (ie, the first control resource set) are located in the uplink subband.

[0082] It should be understood that the network device indicates the frequency domain position of the uplink subband and the frequency domain position of the first frequency domain resource to the terminal device through high-layer signaling. The terminal device can determine that the frequency domain resource (i.e., the first frequency domain resource) used to transmit part or all of the CORESET is located in the uplink subband based on the frequency domain position of the uplink subband and the frequency domain position of the first frequency domain resource. At this time, the first frequency domain resource is not available and cannot be used to transmit part or all of the CORESET.

[0083] In some possible implementations, a CORESET may include one or more resource blocks (RBs) in the frequency domain. The first frequency domain resources may be used to transmit a CORESET. The first frequency domain resources carrying different CORESETs may be located in different subbands.

[0084] S202: The terminal device does not monitor part or all of the control signaling of the CORESET on the first frequency domain resources.

[0085] Here, the control signaling on the CORESET refers to the control signaling in the search space (SS) associated with the CORESET.

[0086] It should be understood that the uplink subband is used to transmit uplink information and cannot transmit CORESET. Then, after determining through S201 that the first frequency domain resource is located in the uplink subband, the terminal device determines that the first frequency domain resource is unavailable. At this time, S202 is executed to not monitor the control signaling in the SS associated with some or all of the CORESETs on the first frequency domain resource.

[0087] In actual applications, one CORESET can be associated with multiple SSs, and one SS is associated with one CORESET.

[0088] For example, Figure 3 This is a schematic diagram of a transmission resource in an embodiment of the present application, see Figure 3 As shown, CORESET1, CORESET2 and CORESET3 are transmitted in different first frequency domain resources respectively. Among them, a part of the frequency domain resources carrying CORESET1 (i.e., the frequency domain resources on time slot 3 (slot3)) is located in the uplink subband. At this time, the terminal device does not perform monitoring of the SS associated with CORESET1 on the frequency domain resources.

[0089] At this point, when the network equipment supports full-duplex, after the terminal device determines that the frequency domain resources used to transmit part or all of the CORESET are within the uplink subband, it confirms that the control area is not on the frequency domain resources, and does not execute the control signaling in the SS associated with part or all of the CORESET on the frequency domain resources. In this way, the frequency domain position of the control area is accurately determined, thereby ensuring the reliability of control information reception.

[0090] In some possible implementations, see Figure 2 As shown, after S202, the above method may further include: S203 to S204.

[0091] S203: The terminal device determines a second frequency domain resource in the downlink subband according to the instruction of the network device.

[0092] It should be understood that the network device may also indicate the frequency domain position of the downlink subband to the terminal device. Then, after determining that the first frequency domain resource is unavailable through the above S201, the terminal device may determine the second frequency domain resource on other frequency domain resources in the downlink subband according to the instruction of the network device or the provisions of the communication protocol. Here, the second frequency domain resource may be used to transmit part or all of the CORESET.

[0093] In one embodiment, the terminal device may determine the second frequency domain resource according to the provisions of the communication protocol. Exemplarily, the communication protocol may stipulate that one or more frequency domain resources other than the first frequency domain resource can be used to transmit part or all of the CORESET, then the terminal device may use the one or more frequency domain resources as the second frequency domain resource. Alternatively, the communication protocol may stipulate a resource offset (such as RB_offset), and the terminal device may offset RB_offset based on the center frequency of the first frequency domain resource to determine the second frequency domain resource.

[0094] In another embodiment, the terminal device may determine the second frequency domain resource according to the indication of the network device. Exemplarily, the terminal device receives the first indication information sent by the network device, and the first indication information is used to indicate the frequency domain position of the second frequency domain resource. Then, the terminal device determines the second frequency domain resource according to the first indication information. In practical applications, the first indication information may include: the frequency domain position of the second frequency domain resource (such as the center frequency point of the second frequency domain resource), the resource offset of the second frequency domain resource relative to the first frequency domain resource (such as RB_offset), etc.

[0095] Of course, the terminal device may determine the second frequency domain resources in other ways, and the embodiments of the present disclosure do not specifically limit this.

[0096] S204: The terminal device monitors part or all of the control signaling associated with the CORESET on the second frequency domain resources.

[0097] It should be understood that after determining the second frequency domain resources, the terminal device can monitor the control signaling in the SS associated with part or all of the CORESETs on the second frequency domain resources.

[0098] For example, Figure 4 This is a schematic diagram of another transmission resource in an embodiment of the present application, see Figure 4 As shown, CORESET1, CORESET2 and CORESET3 are transmitted in different frequency domain resources. Among them, a part of the frequency domain resources of CORESET1 (i.e., the frequency domain resources on time slot 3 (slot3)) is located in the uplink subband. At this time, the terminal device does not monitor the SS associated with CORESET1 on this frequency domain resource. And according to the RB_offset indicated by the network device, another frequency domain resource (which can be called a mirror frequency domain resource, such as other downlink subbands on time slot 3) is determined on other downlink subbands, and the control signaling associated with CORESET is monitored on the mirror frequency domain resource.

[0099] It should be noted that in the embodiment of the present disclosure, the execution order of S202 and S203 is not limited, and the two can be executed successively or simultaneously.

[0100] In the embodiment of the present disclosure, when the network device supports full-duplex, after determining that the frequency domain resources used to transmit part or all of the CORESET are within the uplink sub-band, the terminal device determines other frequency domain resources as the control area, and monitors the control signaling in the SS associated with part or all of the CORESET on the frequency domain resources. In this way, the frequency domain position of the control area is accurately determined, thereby ensuring the reliability of control information reception.

[0101] Based on the same inventive concept, in an embodiment of the present disclosure, a communication method is also provided, which can be applied to a terminal device in the above communication system. In the communication system, the terminal device can communicate with a network device supporting full-duplex.

[0102] Figure 5 FIG. 1 is a schematic diagram of an implementation flow of another communication method on the terminal device side in the embodiment of the present disclosure, see Figure 5 As shown, the method may include:

[0103] S501, the terminal device determines, according to the instruction of the network device, that the fourth frequency domain resources (equivalent to the above-mentioned first frequency domain resources) used to transmit part or all of the CORESET (ie, the second control resource set) are located in the uplink subband.

[0104] S502: The terminal device determines a third frequency domain resource (equivalent to the second frequency domain resource) in the downlink subband according to the instruction of the network device.

[0105] S503: The terminal device monitors part or all of the control signaling associated with the CORESET on the third frequency domain resources.

[0106] It should be noted that the specific implementation process of S501 to S503 can be found in Figure 2 The specific description of S201, S203 to S204 in the embodiment is not repeated here.

[0107] In one embodiment, S502 may determine the third frequency domain resource according to the provisions of the communication protocol. Exemplarily, the communication protocol may stipulate that one or more frequency domain resources other than the fourth frequency domain resource can be used to transmit part or all of the CORESET, then the terminal device may determine the one or more frequency domain resources as the third frequency domain resource. Alternatively, a resource offset (such as RB_offset) may be stipulated in the communication protocol, and the terminal device may offset RB_offset based on the center frequency point of the fourth frequency domain resource to determine the third frequency domain resource.

[0108] In another embodiment, S502 may also determine the third frequency domain resource according to the indication of the network device. Exemplarily, the terminal device receives the second indication information sent by the network device, and the second indication information is used to indicate the frequency domain position of the third frequency domain resource. Then, the terminal device determines the third frequency domain resource according to the second indication information. In practical applications, the second indication information may include: the frequency domain position of the third frequency domain resource (such as the center frequency point of the third frequency domain resource), the resource offset of the third frequency domain resource relative to the fourth frequency domain resource (such as RB_offset), etc.

[0109] Of course, the terminal device may determine the third frequency domain resources in other ways, and the embodiments of the present disclosure do not specifically limit this.

[0110] In the embodiment of the present disclosure, when the network device supports full-duplex, after determining that the frequency domain resources used to transmit part or all of the CORESET are within the uplink sub-band, the terminal device determines other frequency domain resources as the control area, and monitors the control signaling in the SS associated with part or all of the CORESET on the frequency domain resources. In this way, the frequency domain position of the control area is accurately determined, thereby ensuring the reliability of control information reception.

[0111] Based on the same inventive concept, in an embodiment of the present disclosure, a communication method is also provided, which can be applied to a terminal device in a communication system. In the communication system, the terminal device can communicate with a network device supporting full-duplex.

[0112] Figure 6 This is a schematic diagram of an implementation flow of another communication method on the terminal device side in the embodiment of the present disclosure, see Figure 6 As shown, the method may include:

[0113] S601, the terminal device determines, according to the instruction of the network device, a third frequency domain resource for transmitting part or all of the CORESET (i.e., the second control resource set) in multiple downlink subbands that are discontinuous in the frequency domain. Here, the third frequency domain resource can be located in part or all of the multiple downlink subbands.

[0114] It should be understood that the network device can indicate the frequency domain positions of multiple downlink subbands that are discontinuous in the frequency domain to the terminal device through high-level signaling or dynamic signaling. Then, the terminal device determines the third frequency domain resource on the multiple downlink subbands according to the instructions of the network device or the provisions of the communication protocol.

[0115] In one embodiment, S601 may determine the third frequency domain resource according to the indication of the network device. Exemplarily, the terminal device receives the third indication information sent by the network device, and the third indication information is used to indicate the frequency domain positions of multiple downlink subbands and the frequency domain positions of the third frequency domain resources. Then, the terminal device determines the third frequency domain resource according to the third indication information. In practical applications, the third indication information may include: the frequency domain positions of multiple downlink subbands (such as the center frequency of the downlink subband), the center frequency of a downlink subband in multiple downlink subbands and the frequency offset of other downlink subbands relative to the downlink subband, etc., as well as the frequency domain position of the third frequency domain resource (such as the center frequency of the third frequency domain resource), the resource offset of the third frequency domain resource relative to the fourth frequency domain resource (such as RB_offset), etc.

[0116] S602: The terminal device monitors part or all of the control signaling associated with the CORESET on the third frequency domain resources.

[0117] It should be understood that after determining the fifth frequency domain resource, the terminal device can monitor the control signaling in the SS associated with part or all of the CORESET on the fifth frequency domain resource.

[0118] For example, Figure 7 This is a schematic diagram of another transmission resource in the embodiment of the present application, see Figure 7 As shown, in time slot 1, there are 5 working subbands, of which 3 are downlink subbands and 2 are uplink subbands. The terminal device determines the frequency domain positions of the 3 downlink subbands according to the instructions of the network device through high-level signaling. At this time, these 3 downlink subbands can form a virtual bandwidth part. Then, the terminal device uses the frequency domain resources on the three downlink subbands as the third frequency domain resources (which can also be called virtual resources) according to the frequency domain positions of the third frequency domain resources. The terminal device monitors part or all of the control signaling in the SS associated with the CORESET on the third frequency domain resources in the virtual bandwidth part.

[0119] In the embodiment of the present disclosure, when the network device supports full-duplex, the terminal device can determine part or all of the multiple downlink sub-bands as the control area, and listen to the control signaling in the SS associated with the CORESET on the corresponding frequency domain resources. In this way, the frequency domain position of the control area can be accurately determined, thereby ensuring the reliability of control information reception.

[0120] Based on the above Figure 5 and Figure 6The embodiment of the present disclosure also provides a communication method, which is applied to the above-mentioned terminal device. The method may include: the terminal device determines a third frequency domain resource in the downlink subband according to the instruction of the network device; the terminal device monitors the control signaling associated with part or all of the CORESET (i.e., the second control resource set) on the third frequency domain resource.

[0121] It should be understood that the terminal device can determine one or more frequency domain resources on the downlink subband according to the frequency domain position of the downlink subband indicated by the network device, and these frequency domain resources can be used to transmit part or all of the CORESET. Then, the terminal device determines a third frequency domain resource from one or more frequency domain resources of the downlink subband according to the instruction of the network device or the provisions of the communication protocol, and monitors the control signaling associated with part or all of the CORESET on the third frequency domain resource.
