Technical Field

[0002] The present application relates to the field of communications, and in particular, to a communication method and a communication device. Background Art

[0003] When multiple user devices (UEs) transmit data to a network device, link interference may occur between them due to the use of similar or overlapping frequency domain resources. Reducing link interference between UEs is an urgent problem to be solved. Summary of the Invention

[0004] The present application provides a communication method and a communication device for avoiding link interference between user equipment and improving the reliability of data transmission.

[0005] In a first aspect, a communication method is provided. The method can be executed by a first terminal device, or by a module (e.g., a chip or circuit) of the first terminal device, without limitation. For ease of description, the following description is based on an example of execution by the first terminal device.

[0006] The method may include: sending first information to a first network device, the first information is used to determine a first resource, the first resource is used for a first terminal device to communicate with the first network device, and is also used for a second terminal device to communicate with a second network device, the cross-link interference CLI measurement result corresponding to the first resource meets a first condition, the first condition is used to determine the interference resource, and the CLI measurement result is a CLI measurement result between the first terminal device and the second terminal device; sending second information and third information to the second terminal device, the second information is used to determine the first resource, and the third information is used to indicate the priority of communication between the first terminal device and the first network device.

[0007] It should be understood that the first network device and the second network device may be the same network device or different network devices.

[0008] Through the above solution, a first terminal device can indicate a first resource and the priority of the first and second terminal devices to a second terminal device, so that the second terminal device can decide whether to avoid data transmission on the first resource based on the priority. Furthermore, the first terminal device can send first information to a first network device, so that the first network device can schedule resources based on the first information. Through this method, network devices can avoid scheduling resources with high interference, or low-priority users can give way to high-priority users, thereby avoiding cross-link interference.

[0009] In combination with the first aspect, in some implementation methods of the first aspect, the first information includes one or more of the following information: a first resource, a second resource, or a CLI measurement result, wherein the second resource is used for the first terminal device to communicate with the first network device, and is also used for the second terminal device to communicate with the second network device, and the CLI measurement result corresponding to the second resource meets the second condition, and the second condition is used to determine the non-interference resource.

[0010] The aforementioned interference resources refer to resources with a higher CLI interference level, and the non-interference resources refer to resources with a lower CLI interference level.

[0011] Through the above solution, the first terminal device sends the first resource, the second resource, or the CLI measurement result to the first network device, so that the first network device can determine the first resource.

[0012] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving downlink control information, the downlink control information being used to instruct the first terminal device to send first information to the first network device, and to send second information and third information to the second terminal device.

[0013] Through the above scheme, the first terminal device receives the downlink control information sent by the first network device, and sends the first information to the first network device according to the indication of the downlink control information, and sends the second information and the third information to the second terminal device. This method can reduce the indication overhead and reduce the indication delay.

[0014] It should be understood that the first terminal device receiving the downlink control information can be understood as a trigger condition of the method of the first aspect of the present application. Optionally, the method of the first aspect may also have other trigger conditions. For example, after the first terminal device receives the downlink control information, if the first resource does not exist, it does not necessarily send the first information to the first network device and the second information and third information to the second terminal device.

[0015] In combination with the first aspect, in some implementations of the first aspect, the method further includes: determining the first resource and / or the second resource based on the CLI measurement result.

[0016] Through the above solution, the first terminal device can determine the first resource based on the CLI measurement result, and thus can inform the first network device and the second terminal device of the first resource.

[0017] In combination with the first aspect, in some implementations of the first aspect, the CLI measurement result reflects the degree of CLI interference between the first terminal device and the second terminal device, and the first condition is that the CLI interference degree is greater than the interference threshold; the second condition is that the CLI interference degree is less than the interference threshold.

[0019] In combination with the first aspect, in some implementations of the first aspect, the CLI measurement result includes one or more of the following: received signal strength indicator RSSI, reference signal received power RSRP, reference signal received quality RSRQ, or signal to interference plus noise ratio SINR.

[0020] In combination with the first aspect, in some implementation methods of the first aspect, sending first information to the first network device, and sending second information and third information to the second terminal device, includes: when the first resource is determined based on the CLI measurement result and the downlink control information is received, sending the first information to the first network device, and sending the second information and third information to the second terminal device.

[0021] Through the above solution, when there are no complementary resources or no downlink control information is received, the sending of information may not be triggered, thereby reducing useless transmission overhead.

[0022] In combination with the first aspect, in some implementations of the first aspect, the downlink control information indicates at least one of the following information: resources used for sending the first information to the first network device and resources used for sending the second information and the third information to the second terminal device; an identifier of the second terminal device and an identifier of the first network device; a modulation and coding strategy MCS used for sending the first information to the first network device and an MCS used for sending the second information and the third information to the second terminal device; quasi-co-site QCL information used for sending the first information to the first network device and QCL information used for sending the second information and the third information to the second terminal device.

[0029] Through the above solution, when the priority of the first terminal device in communicating with the network device is higher than that of the second terminal device, the first resource is stopped from being used, thereby reducing cross-link interference as quickly as possible.

[0035] Not decoding the second information may also be understood as: ignoring the second information, or using the first resource to communicate with the second network device while ignoring the second information, or stopping decoding the second information.

[0036] Through the above solution, the power consumption of decoding of the second terminal device is reduced and unnecessary decoding operations are avoided.

[0105] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0106] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Fifth Generation (5G) system or New Radio (NR) and future communication systems.

[0107] The following will introduce in detail the system architecture to which the embodiments of the present application can be applied, with reference to specific examples.

[0108] System Architecture 1

[0109] This application can be applied to satellite communication systems.

[0110] As shown in Figure 1, the satellite system architecture may include a satellite base station and terminal-type network elements. The satellite base station provides communication services for terminal devices, which may include smartphones, smart watches, tablet computers, and other devices.

[0111] It should be understood that a satellite base station transmits downlink data to a terminal device, where this downlink data may be encoded using channel coding, and the channel-coded data is then constellation-modulated and transmitted to the terminal device. The terminal device transmits uplink data to the satellite base station, where this uplink data may also be encoded using channel coding, and the encoded data is then constellation-modulated and transmitted to the satellite base station. Satellite base stations can also communicate with ground base stations. Satellites can function as both base stations and terminal devices.

[0112] It should also be understood that the satellite may refer to a drone, a hot air balloon, a low-orbit satellite, a medium-orbit satellite, a high-orbit satellite, etc. Satellite may also refer to a non-ground base station or non-ground equipment, etc.

[0113] System Structure 2

[0114] The present application can be applied to satellite inter-satellite link communication systems.

[0115] As shown in Figure 2, the intersatellite link communication system can be divided into two major components: the acquisition, pointing, and tracking (APT) subsystem and the communication subsystem. The communication subsystem is primarily responsible for intersatellite information transmission and is the core of the intersatellite communication system. The APT system is primarily responsible for acquisition, alignment, and tracking between satellites. Capturing involves determining the incoming signal's direction, and adjusting the transmitted signal's direction toward the receiving end. Throughout the communication process, APT continuously adjusts alignment and acquisition, representing tracking. To minimize the effects of channel attenuation and interference while maintaining high confidentiality and transmission rates, APT must be adjusted in real time to continuously adapt to changes.

[0116] It should be understood that current APT systems are all optical systems. Their disadvantage lies in the difficulty of optical alignment, which requires mechanical adjustment. Existing communication subsystems are mostly optical, with some also operating in the microwave band, often using a single high-gain antenna. Existing APT systems and communication subsystems are independent systems. Disadvantages include optical communication being susceptible to vibration and other factors, resulting in unstable transmission rates; and millimeter-wave frequencies are low, communication capacity is low, and antennas require mechanical adjustment.

[0117] System Architecture 3

[0118] The present application can be applied to a cellular communication system.

[0119] As shown in Figure 3, the present application can be applied to wireless communication systems such as 5G systems and satellite communications. Among them, the wireless communication system is usually composed of cells, each cell contains a base station, and the base station can provide communication services to multiple mobile stations (MS). The base station can include a baseband unit (BBU) and a remote radio unit (RRU). The BBU and RRU can be placed in different places, for example: the RRU is remote and placed in an area with high traffic volume, and the BBU is placed in a central computer room. The BBU and RRU can also be placed in the same computer room. The BBU and RRU can also be different components under a rack.

[0120] It should be understood that the wireless communication systems mentioned in the present application include but are not limited to: Narrow Band-Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data rate for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), Time Division-Synchronization Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), and the three major application scenarios of the next-generation 5G mobile communication system, namely eMBB, URLLC, and eMTC.

[0121] System Architecture 4

[0122] This application can be applied to Internet of Things communication systems.

[0123] Figure 4 shows a typical IoT wireless screen mirroring application scenario. A terminal device (such as a smartphone) establishes a network connection with a TV. The smartphone transmits the content to be projected to the TV. After receiving the content transmitted by the smartphone, the TV displays it on its screen.

[0124] System Architecture 5

[0125] The present application can be applied to integrated access and backhaul (IAB).

[0126] As shown in Figure 5, IAB may include an IAB parent node (IAB Doner), an IAB node (IAB node) and a terminal device. The link between the IAB Doner and the IAB node is a backhaul link, and the link between the terminal device and the IAB node is an access link.

[0127] It should be understood that the above mainly illustrates five system architectures that can be used in this application. Of course, this application can also be applied to other system architectures, which are not listed here one by one.

[0128] It should also be understood that the terminal device in the embodiments of the present application may refer to a user device, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The terminal device may also be a cellular phone, a cordless phone, a smart phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an in-vehicle mobile device, a wearable device, a wireless communication module / chip in a smart factory, a wireless communication module / chip in a smart grid, a wireless communication module / chip in various devices, a terminal device in a 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0129] It should also be understood that the network device in the embodiment of the present application can be a device for communicating with a terminal device. The network device can be a base station (Base Transceiver Station, BTS) in a Global System of Mobile communication (GSM) system or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an evolved base station (Evolutional NodeB, eNB or eNodeB) in an LTE system, or a communication chip / module in a base station, a communication chip / module in a satellite, or a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited.

[0130] In a semi-static sub-band full-duplex (SBFD) uplink (UL) subband, frequency domain resources account for approximately 20% to 25% of the bandwidth. Dynamic SBFD provides more flexible uplink and downlink allocation, allowing the base station to flexibly configure uplink and downlink transmissions at the same time based on uplink and downlink traffic. Compared to dynamic time division duplex (TDD), dynamic SBFD allows for UL transmissions at any time, resulting in lower latency.

[0131] Whether it is SBFD, full-duplex communication, or hybrid full-duplex and half-duplex communication (for example, sub-band full-duplex), all face serious cross-link interference (CLI) between user equipment (UE). This application uses the SBFD scenario as an example, and is also applicable to communication scenarios such as full-duplex communication, hybrid full-duplex and half-duplex communication, which generate inter-UE interference. This application does not limit the application scenarios of the technical solution.

[0132] Inter-UE interference includes the following two types of interference:

[0133] The following are two scenarios of inter-UE CLI interference:

[0134] 1) As shown in FIG6 , UE1 communicates with base station 1 , and UE2 communicates with base station 2 .

[0135] As shown in (a) of Figure 7 , the frame structures of base station 1 and base station 2 may be different, and UE1's downlink may be subject to intra-subband interference from UE2's uplink; or, as shown in (b) of Figure 7 , the frame structures of base station 1 and base station 2 may be the same, and UE1's downlink may be subject to inter-subband interference from UE2's uplink.

[0136] 2) As shown in FIG8 , UE1 and UE2 both communicate with base station 1 .

[0137] As shown in FIG7( b ), the frame structures of the two users are the same, and the downlink of UE1 may be interfered with by the uplink inter-subband of UE2.

[0138] This application provides a variety of communication methods, which are used in communication scenarios with low latency and high reliability requirements. They can reduce cross-link interference CLI interference between UEs and improve communication reliability.

[0139] It should be understood that the description of the specific scenarios in the embodiments of the present application is only an example. In addition to being applicable to the application scenarios described above, the methods provided in the embodiments of the present application are also applicable to application scenarios with similar problems.

[0140] In the description of the embodiments of the present application, unless otherwise specified, "a plurality of" or "a plurality of" means two or more. In addition, "at least one" can be replaced by "one or more".

[0141] The ordinal numbers "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the size, content, order, timing, priority, or importance of the multiple objects. For example, the first indication information and the second indication information can be the same information or different information, and such names do not indicate differences in the content, size, application scenario, sender / receiver, priority, or importance of the two messages. In addition, the numbering of the steps in the various embodiments introduced in this application is only for distinguishing different steps and is not used to limit the order of the steps.

[0142] The technical solutions provided in the embodiments of this application can be applied to wireless communications between communication devices. Wireless communications between communication devices may include: wireless communications between network devices and terminals, wireless communications between network devices, and wireless communications between terminals. In the embodiments of this application, the term "wireless communications" may also be referred to as "communication," which may also be described as "data transmission," "information transmission," or "transmission."

[0143] It should be understood that the names of all nodes and messages in this application are merely names set for the convenience of description in this application. The names in the actual network may be different. This application should not be understood as limiting the names of various nodes and messages. On the contrary, any name with the same or similar function as the node or message used in this application is regarded as a method or equivalent replacement of this application, and is within the scope of protection of this application. No further details will be given below.

[0144] In this application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal, and can include directly or indirectly sending information to the terminal. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal, and can include directly or indirectly receiving information from the terminal. The information may undergo necessary processing between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0145] The following describes in detail various communication methods provided in the embodiments of the present application with reference to the accompanying drawings.

[0146] It should be understood that the step numbers in the embodiments of the present application are for illustration only and do not limit the order in which the steps occur.

[0147] For ease of understanding and explanation, the following describes the communication method of the embodiment of the present application by taking the interaction between the terminal device and the network device as an example, but this should not constitute any limitation on the execution subject of the communication method of the embodiment of the present application. For example, the method performed by the terminal device can also be performed by a module (such as a circuit, a chip or a chip system, etc.) of the terminal device, and can also be implemented by a logical node, a logical module or software that can realize all or part of the terminal device function. The method performed by the network device can also be performed by a module (such as a circuit, a chip or a chip system, etc.) of the network device, and can also be implemented by a logical node, a logical module or software that can realize all or part of the network device function.

[0148] FIG9 shows a communication method 900 provided in the present application. The method 900 includes at least part of the content shown in FIG9 . The method 900 is applicable to the scenario shown in FIG6 .

[0149] S910, UE1 (i.e., an example of a first terminal device) determines a first resource and / or a second resource based on a CLI measurement result between UE1 and UE2 (i.e., an example of a second terminal device).

[0150] It should be understood that the first resource is used for UE1 to communicate with base station 1 (i.e., an example of the first network device), and is also used for UE2 to communicate with base station 2 (i.e., an example of the second network device); and the second resource is used for UE1 to communicate with base station 1, and is also used for UE2 to communicate with base station 2.

[0151] Specifically, UE1 allocates resources into first resources and second resources based on the CLI measurement result between UE1 and UE2, wherein the first resources are resources with a higher CLI interference level, and the second resources are resources with a lower CLI interference level.

[0152] The first resource and the second resource may be time-frequency resources or frequency-domain resources only. It should be understood that for semi-static SBFD, the first resource and the second resource may be frequency-domain resources only, thereby reducing the overhead of indicating the first resource and / or the second resource to base station 1 or UE 2.

[0153] Exemplarily, the first resource may also be referred to as a complementary resource or an interference resource, and the second resource may also be referred to as an anchor resource or a non-interference resource, which is not limited in this application.

[0154] Exemplarily, the above-mentioned UE1 may be a URLLC UE, and UE2 may be an eMBB UE.

[0155] Exemplarily, the above-mentioned UE1 may also be a high-priority service UE, and UE2 may be a low-priority service UE.

[0156] Exemplarily, the above-mentioned UE1 and UE2 may also be services with the same priority.

[0157] Optionally, the measurement configured / indicated by the network device may be a CLI measurement of different frequency domain units.

[0158] Optionally, the above CLI measurement may be a CLI-Sounding Reference Signal (SRS) measurement scheduled by the group DCI. For example, the group DCI schedules UE1 to measure the CLI-SRS or SRS of UE2.

[0159] Optionally, the above CLI measurement may be measurement of reference signals such as CSI / DMRS scheduled by base station 1 for UE1, or base station 1 may use a high layer to configure dedicated CLI measurement resources and schedule UE1 to use the resources to measure CLI.

[0160] For multiple frequency domain units, multiple CLI measurement results can be included. The unit of each frequency domain unit can be 5RB, 10RB, etc. This application does not limit the unit of a single frequency domain unit. Different frequency domain units can be the same or different in size. Different frequency domain units can overlap partially or completely, or they can not overlap.

[0161] CLI measurement results can be at least one of the following:

[0162] 1) Received Signal Strength Indication (RSSI);

[0163] 2) Reference Signal Received Power (RSRP);

[0164] 3) Reference Signal Received Quality (RSRQ);

[0165] 4) Signal to Interference plus Noise Ratio (SINR)

[0166] In a possible implementation, UE1 allocates resources into first resources and second resources based on the CLI measurement result between UE1 and UE2, including: UE1 determines resources that meet the first condition as the first resource, and determines resources that meet the second condition as the second resource.

[0167] Optionally, the first condition is that the CLI interference level is greater than an interference threshold, and the second condition is that the CLI interference level is less than the interference threshold.

[0168] Optionally, the first condition is that the CLI interference level is greater than or equal to an interference threshold, and the second condition is that the CLI interference level is less than the interference threshold.

[0169] Optionally, the first condition is that the CLI interference level is greater than an interference threshold, and the second condition is that the CLI interference level is less than or equal to the interference threshold.

[0170] Optionally, the interference threshold is predefined by the protocol or configured by a high-level layer. For example, the interference threshold is related to one or more of the following parameters: received signal strength indicator RSSI, reference signal received power RSRP, reference signal received quality RSRQ, or signal to interference plus noise ratio SINR.

[0171] S920 , base station 1 sends downlink control information (DCI) to UE1 .

[0172] Specifically, the downlink control information is used to instruct UE1 to send first information to base station 1, and to send second information and third information to UE2. The first information is used to determine the first resource, the second information is used to determine the first resource, and the third information is used to indicate the priority of UE1 communicating with the base station.

[0173] The first information includes one or more of the following information: a first resource, a second resource, or a CLI measurement result.

[0174] Base station 1 sends downlink control information to UE1.

[0175] Optionally, the downlink control information instructs UE1 to send information to base station 1 and UE2 on different time-frequency resources.

[0176] Exemplarily, the downlink control information indicates at least one of the following information:

[0177] 1) Resources used to send the first information to base station 1 (such as first sending resources), and resources used to send the second information and third information to UE 2 (such as second sending resources). Optionally, the resources are time-frequency resources.

[0178] The base station 1 indicates the first sending resource and the second sending resource to the UE 1 through downlink control information, and the specific indication manner includes joint indication or separate indication.

[0179] Separate indication: Indicate the first transmission resource and the second transmission resource separately. For example, base station 1 indicates the first transmission resource to UE1 and indicates the second transmission resource to UE1.

[0180] Joint indication: indicates a group of resources, where the group of resources includes a first sending resource and a second sending resource, and indicates which of the group of resources are the first sending resources or which are the second sending resources.

[0181] 2) The identifier of UE2 and the identifier of base station 1;

[0182] 3) The modulation and coding scheme (MCS) used in sending the first information to base station 1, and the MCS used in sending the second information and the third information to UE 2;

[0183] 4) Sending first Quasi Co-Location (QCL) information used for the first information to base station 1, and sending second QCL information used for the second information and third information to UE 2. Optionally, the QCL information includes information related to CSI-RS resources or SRS resources, or includes spatial domain information of different panels, or includes spatial domain information such as different beams.

[0184] Optionally, the downlink control information instructs UE1 to send information to base station 1 and UE2 on the same time-frequency resources.

[0185] Specifically, the two links for sending information to base station 1 and UE 2 use the same time-frequency resources, but different space resources.

[0186] In this case, the downlink control information indicates at least one of the following information:

[0187] 1) One time-frequency resource. This time-frequency resource is used by UE1 to send first information to base station 1, and is also used by UE1 to send second information and third information to UE2.

[0188] 2) The identifier of UE2 and the identifier of base station 1;

[0189] 3) The modulation and coding scheme (MCS) used in sending the first information to base station 1, and the MCS used in sending the second information and the third information to UE 2;

[0190] 4) First Quasi Co-Location (QCL) information used in sending the first information is sent to base station 1, and second QCL information used in sending the second information and the third information is sent to UE2.

[0191] Optionally, the protocol predefines a special DCI format and a size of the DCI format, and the DCI in this format instructs UE1 to send the first information to base station 1, and to send the second information and the third information to UE2.

[0192] Optionally, base station 1 indicates the DCI format through higher layer signaling, or downlink control information carries DCI format information.

[0193] Optionally, the downlink control information indicates that the transmission is a low-latency and high-reliability transmission, such as URLLC, so that UE1 transmits based on predefined resources.

[0194] Optionally, a fixed larger resource (such as 20 RE) or a more reliable MCS is predefined to ensure transmission reliability.

[0195] Optionally, the downlink control information is repeatedly transmitted multiple times to ensure the reliability of the downlink control information transmission.

[0196] S930, UE1 sends first information to base station 1, and sends second information and third information to UE2.

[0197] In step S930 , a trigger condition exists. When the trigger condition is met, UE1 sends the first information to base station 1 and sends the second information and the third information to UE2; otherwise, the above information is not sent.

[0198] The trigger conditions include:

[0199] 1) receiving the downlink control information DCI described in step S920;

[0200] 2) The first resource exists.

[0201] The encoding method of the second information and the third information is introduced below.

[0202] The second information and the third information can be coded and modulated separately or jointly coded and modulated.

[0203] In a possible implementation manner, the second information and the third information are coded and modulated separately.

[0204] In this case, for UE2, the third information is decoded first, and the priorities of UE1 and UE2 are compared. When the priority of UE1 is higher, UE2 decodes the second information; when the priority of UE2 is higher or the priorities of UE1 and UE2 are the same, UE2 no longer decodes the second information.

[0205] In another possible implementation, the second information and the third information are jointly coded and modulated, the third information can be mapped in the priority decoding bit string, and a separate cyclic redundancy check (CRC) or other verification method is used to determine whether the priority is decoded correctly.

[0206] In this case, for UE2, when the priority of UE1 is higher, UE2 decodes the second information; when the priority of UE2 is higher or the priorities of UE1 and UE2 are the same, UE2 no longer decodes the second information.

[0207] By using the above method, the decoding energy consumption of UE2 can be reduced and unnecessary decoding operations can be avoided.

[0208] UE1 sends first information to base station 1, where the first information includes one or more of the following information: first resources, second resources, or CLI measurement results.

[0209] After receiving the first information, base station 1 performs the following operations:

[0210] In one possible implementation, UE1 sends a CLI measurement result to base station 1. Base station 1 can then independently allocate the first resource or the second resource, or independently determine an interference threshold. This interference threshold may be different from or the same as the interference threshold for the first and second resources determined by UE1. Base station 1 can independently determine which resources to schedule based on the first and second resources determined by itself.

[0211] Specifically, after base station 1 receives the first information, if base station 1 knows the priority of UE2 (such as ideal backhaul), when the priority of UE1 is not higher than the priority of UE2, base station 1 avoids scheduling the first resource or prioritizes scheduling the second resource; or, if base station 1 does not know the priority of UE2, it avoids scheduling the first resource or prioritizes scheduling the second resource.

[0212] Therefore, when the priorities of UE1 and UE2 are the same, base station 1 can reduce CLI interference through scheduling.

[0213] After receiving the second information and the third information, UE2 performs the following operations:

[0214] After receiving the second information and the third information sent by UE1, UE2 determines whether to use the first resource to communicate with base station 2 based on the priorities of UE1 and UE2.

[0215] In one implementation, the priority of UE1 is higher than that of UE2. When UE2 is a full-duplex UE or a UE configured with grant, UE2 may stop communicating with base station 2 through the first resource, thereby reducing CLI interference as quickly as possible.

[0216] S940, UE2 sends uplink control information to base station 2.

[0217] In one implementation, if the priority of UE1 is greater than that of UE2, UE2 sends uplink control information to base station 2, where the uplink control information includes second information. The uplink control information is used to indicate to avoid scheduling UE2 for uplink communication through the first resource and to use uplink transmission resources other than the first resource, thereby reducing CLI interference.

[0218] Optionally, UE2 sends uplink control information to base station 2 through a third resource, where the third resource is different from the first resource.

[0219] In another implementation, if the priority of UE1 is not higher than the priority of UE2, UE2 does not perform any operation.

[0220] FIG10 shows a communication method 1000 provided in the present application. The method 1000 includes at least part of the content shown in FIG10 . The method 1000 is applicable to the scenario shown in FIG8 .

[0221] S1010, UE1 (i.e., an example of a first terminal device) determines a first resource and / or a second resource based on a CLI measurement result between UE1 and UE2 (i.e., an example of a second terminal device).

[0222] It should be understood that the first resource is used for UE1 and UE2 to communicate with base station 1 (ie, an example of the first network device); and the second resource is used for UE1 and UE2 to communicate with base station 1.

[0223] It should be understood that UE1 and UE2 communicate with the same base station, the frame structures of UE1 and UE2 are the same, and the first resource and the second resource may only be frequency domain resources.

[0224] Step 1010 refers to step S910.

[0225] S1020, base station 1 sends downlink control information (Downlink Control Information, DCI) to UE1, where the downlink control information instructs UE1 to send first information to base station 1 and send second information and third information to UE2.

[0226] Step 1020 refers to step S920.

[0227] S1030, base station 1 schedules UE2 to receive the second information and the third information.

[0228] Specifically, base station 1 may send fourth information to UE 2, thereby instructing UE 2 to receive the second information and the third information. Optionally, the fourth information may be downlink control information.

[0229] Optionally, the scheduling information sent by base station 1 to UE1 in S1020 and the scheduling information (ie, fourth information) sent by base station 1 to UE2 in S1030 may be in the same downlink control information or in different downlink control information.

[0230] S1040, UE1 sends first information to base station 1, and sends second information and third information to UE2.

[0231] Step 1040 refers to step S930.

[0232] After receiving the first information, base station 1 performs the following operations:

[0233] In one possible implementation, UE1 sends a CLI measurement result to base station 1. Base station 1 can then independently allocate the first resource or the second resource, or independently determine an interference threshold. This interference threshold may be different from or the same as the interference threshold for the first and second resources determined by UE1. Base station 1 can independently determine which resources to schedule based on the first and second resources determined by itself.

[0234] Specifically, after base station 1 receives the first information, when the priority of UE1 is not higher than the priority of UE2, base station 1 avoids scheduling the first resource or prioritizes scheduling the second resource for UE1's communication; or, when the priority of UE1 is higher than the priority of UE2, base station 1 can avoid scheduling the first resource or prioritize scheduling the second resource for UE2's communication.

[0235] Therefore, base station 1 can reduce CLI interference through scheduling.

[0236] It should be understood that for a UE with a lower priority between UE1 and UE2, base station 1 may preferentially schedule the second resource or reschedule other resources for communicating with base station 1.

[0237] After receiving the second information and the third information, UE2 performs the following operations:

[0238] After receiving the second information and the third information sent by UE1, UE2 determines whether to use the first resource to communicate with base station 2 based on the priorities of UE1 and UE2.

[0239] In one implementation, if UE1 has a higher priority than UE2, then when UE2 is a full-duplex UE or a UE configured with a grant, UE2 may stop communicating with base station 2 using the first resource, thereby reducing CLI interference as quickly as possible. Optionally, UE2 may monitor resources rescheduled by base station 1 for communication with base station 1.

[0240] Optionally, the expiration time of the first resource and the second resource may be predefined. For example, when the frame structure changes or UE1 resends the CLI measurement result to base station 1 and UE2, the original first resource and the second resource become invalid.
