Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 29, 2023, with application number 202311101935.4 and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0003] The future sixth-generation mobile communication technology system (6th generation mobile networks or 6th generation wireless systems, 6G) may have two features: one is the use of multiple discontinuous bandwidths, and the other is the introduction of simultaneous full-duplex technology on the same frequency.

[0004] The use of multiple discontinuous bandwidths is driven by the fact that 6G will pursue higher data rates, which inevitably require higher transmission bandwidths. However, the spectrum resources controlled by various operators are not necessarily contiguous and may consist of multiple fragmented bandwidth resources. Simultaneous full-duplex technology emerged because it can greatly improve the utilization efficiency of time and frequency resources, ideally even doubling the efficiency.

[0005] However, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in non-contiguous spectrum scenarios.

[0049] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new radio (NR) systems, and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architecture, dual-connection architecture, vehicle-to-everything architecture and other architectures.

[0050] This application mainly relates to the communication between terminal devices and network devices. Among them:

[0051] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second generation (2nd-Generation, 2G) network, the device providing the base station function includes a base transceiver station (Base Transceiver Station, BTS), in the third generation (3rd-Generation, 3G) network, the device providing the base station function includes a node B (NodeB), in the fourth generation (4th-Generation, 4G) network, the device providing the base station function includes an evolved node B (evolved NodeB, eNB), in the wireless local area network (Wireless Local Area Networks, WLAN), the device providing the base station function is an access point (Access Point, AP), and the device providing the base station function in NR is the next generation Node Base station (gNB), and the further 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 gNB and ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application also includes a device that provides a base station function in a future new communication system, etc.

[0052] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal equipment may also be a cellular phone, a cordless 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, a vehicle-mounted device, a wearable device, a terminal device in a future 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. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0053] As described in the background art, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in a non-contiguous spectrum scenario.

[0054] The judgment on the future evolution of full-duplex technology is as follows: the overall trend is divided into four stages. Taking into account the differences in base station types deployed by different operators and the differences in duplex types supported by terminal devices themselves, there can be different permutations and combinations.

[0055] When one side uses the same frequency and full-duplex mode, the combined duplex modes on the network and terminal sides can be divided into the following five categories:

[0056] Category 1: full-duplex on the same frequency and at the same time on the network side, and half-duplex on the terminal device side, such as frequency division duplexing (FDD) or time division duplexing (TDD).

[0057] Category 2: simultaneous and same-frequency full-duplex on the network side and sub-band half-duplex on the terminal device side.

[0058] Category 3: simultaneous same-frequency full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal device side.

[0059] Category 4: half-duplex on the network side and full-duplex on the terminal device side at the same time and frequency.

[0060] Category 5: sub-band full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal side.

[0061] The scenarios described in categories 3 and 4 may be that a terminal device is roaming, where an advanced terminal device roams into a relatively backward mobile network. The technical solution of the present application can be used in any of the above five scenarios.

[0062] The technical solution of the present application implements the configuration of the duplex type on the time domain resource unit through the first configuration information, and by introducing a new duplex type full-duplex, full-duplex transmission is achieved on the entire non-continuous spectrum, thereby improving communication quality.

[0063] The configuration or configuration information mentioned in the present invention can be indicated by the network layer through high-layer signaling (such as RRC) or through dynamic signaling indication (such as DCI).

[0064] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] Referring to FIG1 , the method provided in this application specifically includes the following steps:

[0066] Step 101: A network device sends first configuration information, where the first configuration information indicates a duplex type for each time domain resource unit, where the duplex type includes full duplex. Correspondingly, a terminal device receives the first configuration information.

[0067] Step 102: The terminal device and the network device perform uplink transmission, downlink transmission and / or simultaneous uplink and downlink transmission according to the first configuration information.

[0068] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0069] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0070] In one non-limiting embodiment, the duplex type is selected from uplink, downlink, and full-duplex.

[0071] In a non-limiting embodiment, the time domain resource unit may be any implementable time unit such as a radio frame, a subframe, a time slot, a symbol, etc., and this application does not impose any limitation on this.

[0072] In this embodiment, the configuration of the duplex type on the time domain resources can be achieved through the first configuration information. In order to achieve simultaneous full-duplex on the same frequency, the terminal device also needs to know the configuration of the duplex type on the frequency domain resources.

[0073] To achieve the above objectives, a separate duplex type configuration may be performed for each frequency domain resource unit. In a specific embodiment, the duplex type may be configured for each time domain resource unit on one or more frequency domain resources using the first configuration information, and the duplex type may be configured for each frequency domain resource unit in the one or more frequency domain resources one by one.

[0074] Specifically, the frequency domain resource unit can be the size of the frequency domain resources occupied by the resource block (RB), the size of the frequency domain resources occupied by the resource element (RE), the size of the frequency domain resources occupied by an integer multiple of RB, the size of the frequency domain resources occupied by an integer multiple of RE, or a subband, etc.

[0075] For example, the terminal device may obtain the duplex type on the time domain resources corresponding to one or more sub-bands based on the first configuration information. The duplex type on the one or more sub-bands may be obtained through other configuration information.

[0076] It should be noted that the first configuration information of the duplex type for time domain resources and other configuration information of the duplex type for frequency domain resources can be included in the same high-level signaling or in different high-level signaling, and this application does not impose any restrictions on this.

[0077] In another specific implementation, the duplex type of each frequency domain resource unit may be configured first, and then, based on this, the time domain resource unit whose duplex type is full duplex may be additionally indicated.

[0078] In a non-limiting embodiment, the first configuration information includes duplex types of uplink (also called half-duplex uplink), downlink (also called half-duplex downlink), full-duplex, and the location of the flexible time domain resource unit.

[0079] The duplex types in this embodiment are independent of each other. Specifically, the first configuration information may include the absolute position of the time domain resource unit of each duplex type, for example, the absolute position is the starting position and offset of the time domain resource unit.

[0080] Specifically, please refer to Figure 2 , where D indicates that the duplex type is downlink, U indicates that the duplex type is downlink, X indicates that the duplex type is flexible (corresponding to the flexible resources in the existing communication system), and D+U indicates that the duplex type is full duplex. D, U, X, and D+U may specifically include one or more identical time domain resource units, or may specifically include one or more different types of time domain resource units. For example, D, U, X, and D+U may include one or more time slots, and optionally, one or more symbols may be added. Alternatively, D, U, X, and D+U may include one or more symbols. The above explanation may also be applied to other embodiments of the present invention.

[0081] Taking the time slot as an example, in the duplex configuration shown in Figure 2a, the duplex type for time slots 0 to 3 is downlink, the duplex type for time slots 4 to 6 is flexible, the duplex type for time slots 7 and 8 is full duplex, and the duplex type for time slots 9 to 13 is uplink. The time slot configuration shown in Figure 2a can be used as a basic configuration pattern, with D, X, D+U, and U as a basic pattern, which then periodically repeats in the time domain.

[0082] In the duplex configuration shown in Figure 2b, the duplex type for timeslots 0 to 3 is downlink, the duplex type for timeslots 4 to 8 is flexible, the duplex type for timeslots 9 and 10 is full duplex, and the duplex type for timeslots 11 to 13 is uplink. The timeslot configuration shown in Figure 2b can be used as a basic configuration pattern, i.e., D, X, U, and D+U are used as a basic pattern, which then periodically repeats in the time domain.

[0083] In the duplex configuration shown in Figure 2c, the duplex type for timeslots 0 to 3 is downlink, the duplex type for timeslot 4 is full duplex, the duplex type for timeslots 6 to 8 is flexible, and the duplex type for timeslots 9 to 13 is uplink. The timeslot configuration shown in Figure 2c can be used as a basic configuration pattern, with D, D+U, X, and U as a basic pattern, which then periodically repeats in the time domain.

[0084] Optionally, other basic patterns may be other permutations and combinations of D, U, X, and D+U, which are not limited by the present invention. In another non-limiting embodiment, the first configuration information includes the absolute positions of time-domain resource units with uplink, downlink, and flexible duplex types, and the relative positions of time-domain resource units with full-duplex duplex type within the time-domain resource units with flexible duplex type.

[0085] In this embodiment, the time domain resource unit with full duplex is nested within the time domain resource units of other types. Therefore, the first configuration information includes the relative position of the time domain resource with full duplex and the absolute position of the time domain resource units of other duplex types. The absolute position can be calculated from the starting time domain position and / or ending time domain position and / or time domain duration of the full duplex time domain resource.

[0086] [Corrected 05.09.2024 according to Rule 91] Taking the time domain resource unit as a time slot as an example, in the duplex configuration shown in Figure 3d, the time slot with the duplex type of full duplex is nested in the time domain resource unit with the duplex type of flexible.

[0087] [Corrected 05.09.2024 according to Rule 91] In the duplex configuration shown in FIG3e , the time slots of the duplex type being full duplex are nested in the time domain resource units of the duplex type being downlink.

[0088] [Corrected 05.09.2024 according to Rule 91] In the duplex configuration shown in Figure 3f, the time slots with the duplex type of full duplex are nested in the time domain resource units with the duplex type of uplink.

[0089] In a non-limiting embodiment, the terminal device can receive fourth configuration information, wherein the fourth configuration information includes the position of a first frequency domain resource unit whose duplex type is uplink and a second frequency domain resource unit whose duplex type is downlink, wherein the first configuration information includes the position of a first time domain resource unit whose duplex type is full-duplex corresponding to the first frequency domain resource unit and / or the second frequency domain resource unit.

[0090] The embodiment of the present invention introduces limited time domain resource units to perform simultaneous and co-frequency full-duplex transmission on the basis of frequency division duplexing (FDD).

[0091] Specifically referring to FIG. 4 , FDD is configured on sub-bands 1 to 4 , wherein the duplex type on sub-bands 1 and 2 is downlink, and the duplex type on sub-bands 3 and 4 is uplink.

[0092] Based on the above FDD, the corresponding duplex type is configured in subframes 0 to 4. Specifically, the duplex type is configured as full duplex for symbols 4 to 9 of subframe 0 and all symbols of subframe 2 corresponding to subband 2. In this case, the first time domain resource unit is symbols 4 to 9 of subframe 0 and all symbols of subframe 2.

[0093] On subband 4, the duplex type is configured as full duplex for symbols 9 to 13 of subframe 0 and all symbols of subframe 1. In this case, the first time domain resource unit is symbols 9 to 13 of subframe 0 and all symbols of subframe 1.

[0094] Furthermore, the first configuration information in the embodiment of the present invention can be repeated periodically. For example, FIG4 shows that the first configuration information includes a duplex configuration for five subframes (i.e., 5 ms). The repetition period can be set to 5 ms. Then, every five subsequent subframes will be consistent with the duplex configuration for the five subframes shown in FIG4 .

[0095] In a specific embodiment, the terminal device may receive a bitmap, where each bit in the bitmap corresponds to a respective time domain resource unit, and each bit indicates whether the duplex type is full duplex. The bitmap may be periodically circulated in the time domain.

[0096] For example, the bit map is 11001, corresponding to the duplex configuration on 5 subframes, where 1 indicates that the duplex type is full-duplex and 0 indicates that the duplex type is non-full-duplex; or, 0 indicates that the duplex type is full-duplex and 1 indicates that the duplex type is non-full-duplex.

[0097] In another specific embodiment, the terminal device receives high-layer signaling, where the high-layer signaling includes the location of the first time-domain resource unit.

[0098] Specifically, the position of the first time domain resource unit can be carried in downlink control information (DCI). In this way, the time domain resources with a duplex type of full duplex can be dynamically configured, which has higher flexibility.

[0099] In a non-limiting embodiment, the duplex type of each time domain resource unit may be configured as full duplex through first configuration information, and then the position of the second time domain resource unit with uplink duplex type and / or the position of the third time domain resource unit with downlink duplex type may be configured through third configuration information.

[0100] In this embodiment of the present invention, the time domain resource unit has an initial duplex type, specifically full duplex, which can be configured using the first configuration information. The third configuration information may include the position of a second time domain resource unit with an uplink duplex type and / or the position of a third time domain resource unit with a downlink duplex type, thereby completing the complete duplex configuration for each time domain resource.

[0101] More specifically, the third configuration information may be in the form of a bitmap, where a target bit value indicates an uplink duplex type or a downlink duplex type. For example, the target value is 1. Different bitmaps are used to configure the uplink duplex type and the downlink duplex type.

[0102] For details, please refer to Figure 5. As shown in Figure 5, the duplex type on all eight symbols is full-duplex D+U. The second time-domain resource unit with an uplink duplex type is the fifth symbol, and the corresponding bit pattern is 00001000. Similarly, the third time-domain resource unit with a downlink duplex type is the second, fourth, sixth, and eighth symbols, and the corresponding bit pattern is 01010101. The bit pattern may be periodically cycled in the time domain.

[0103] In one variation, the duplex type of each time domain resource unit is first configured as uplink through the first configuration information. The third configuration information may then include the location of time domain resources with full duplex type and / or the location of time domain resources with downlink duplex type, thereby completing the complete duplex configuration for each time domain resource. The location of the time domain resource may be calculated based on the starting time domain location and / or ending time domain location and / or the time domain duration of the time domain resource.

[0104] In another variation, the duplex type of each time domain resource unit is first configured as downlink through the first configuration information. The third configuration information may then include the location of time domain resources with full duplex type and / or the location of time domain resources with uplink duplex type, thereby completing the complete duplex configuration for each time domain resource. The location of the time domain resource may be calculated from the starting time domain location and / or ending time domain location and / or the time domain duration of the time domain resource.

[0105] Furthermore, the third configuration information in the embodiment of the present invention may be periodically circulated. The specific cycle size and / or cycle offset value may be pre-agreed by the network device and the terminal device, or specified by a communication standard protocol, or configured by the network side through high-layer signaling (such as RRC) or dynamic signaling (such as DCI), and this application does not impose any restrictions on this.

[0106] In a non-limiting embodiment, this application further discloses a communication method. Specifically, referring to FIG. 6 , the method may further include step 601: a network device sends fourth configuration information to a terminal device, the fourth configuration information being used to indicate a duplex type for each frequency domain resource unit. Accordingly, the terminal device receives the fourth configuration information.

[0107] In this embodiment, the duplex configuration of the time domain resources is implemented through the first configuration information, and the duplex configuration of the frequency domain resources is implemented through the fourth configuration information. The duplex configuration scheme on the frequency domain resources is described in detail below.

[0108] Specifically, on some sub-bands with a bandwidth less than the preset bandwidth, the network side can adopt a simultaneous, same-frequency, full-duplex configuration. Conversely, on some sub-bands with a bandwidth greater than or equal to the preset bandwidth, the network side can adopt a traditional half-duplex configuration (i.e., only downlink or only uplink). This is because full-duplex has higher requirements for anti-interference capabilities, and the magnitude of anti-interference capabilities is inversely proportional to the sub-band bandwidth. Therefore, in order to ensure communication quality, the network side can adopt a simultaneous, same-frequency, full-duplex configuration on sub-bands with a bandwidth less than the preset bandwidth. The preset bandwidth can be determined in a predefined manner, or the value of the preset bandwidth can be determined based on the full-duplex capability of the network-side device or the terminal device.

[0109] Similarly, on the terminal device side, on some sub-bands with a bandwidth less than the preset bandwidth, the terminal device can adopt a simultaneous and same-frequency full-duplex configuration; conversely, on some sub-bands with a bandwidth greater than or equal to the preset bandwidth, the terminal device can adopt a traditional half-duplex configuration.

[0110] In a non-limiting embodiment, the network device may inform the terminal device of its capabilities via broadcast signaling or Radio Resource Control (RRC) signaling. Specifically, the capabilities of the network device include the bandwidth and / or center frequency and / or sub-band supported by the network device for simultaneous full-duplex communication.

[0111] In a non-limiting embodiment, the terminal device may also consider informing the network device of its capabilities through high-layer signaling by reporting its capabilities. Specifically, the capabilities of the terminal device include the bandwidth / frequency / sub-band that the network device supports for simultaneous full-duplex operation.

[0112] Furthermore, when reporting its capabilities, terminal devices can also report their device type. For terminal devices that support simultaneous, same-frequency, full-duplex, their device type is different from that of other terminal devices that support half-duplex or SBFD. In other words, terminal devices that support simultaneous, same-frequency, full-duplex have a new device type. This new device type can be considered an enhancement of TDD / FDD or SBFD.

[0113] It should be noted that the new device type of the above-mentioned terminal device can be any other feasible name and can be specified in the communication standard protocol, and this application does not impose any restrictions on this.

[0114] In a non-limiting embodiment, the duplex type on the frequency domain resource unit is selected from uplink, downlink, and full duplex.

[0115] [Corrected 05.09.2024 according to Rule 91] Specifically, full-duplex may include simultaneous same-frequency full-duplex and time-division duplex. Therefore, when the terminal device learns from the first configuration information that the full-duplex type is full-duplex, it is necessary to further distinguish between same-frequency full-duplex and time-division duplex.

[0116] Method 1: The terminal device receives a third configuration, and the third configuration is used to indicate that the duplex type of the first frequency domain resource unit is time division duplex or simultaneous frequency full duplex.

[0117] [Corrected 05.09.2024 according to Rule 91] For example, the second configuration information occupies one bit. When the value of this bit is 1, it indicates that the duplex type is simultaneous and same-frequency full-duplex; when the value of this bit is 0, it indicates that the duplex type is time-division duplex. The reverse is also true: when the value of this bit is 0, it indicates that the duplex type is simultaneous and same-frequency full-duplex; when the value of this bit is 1, it indicates that the duplex type is TDD.

[0118] In method 2, the terminal device distinguishes the duplex mode based on the time-domain time division duplex configuration of the first frequency-domain resource unit. For example, whether the frequency-domain resource unit is configured with legacy TDD-DL-UL-SlotConfiguration, if yes, indicates that the duplex mode is TDD; otherwise, it indicates that the duplex mode is simultaneous, same-frequency, full-duplex.

[0119] For a terminal device, it can obtain the duplex configuration of all subbands, or only the duplex configuration of the subband it is in. The duplex configuration can be UE-specific configuration information or cell-specific configuration information.

[0120] In a non-limiting embodiment, the fourth configuration information includes a common configuration for multiple frequency domain resource units and a dedicated configuration for the target frequency domain resource unit, wherein the dedicated configuration includes full duplex. Specifically, the network device may send cell-specific high-layer signaling to the terminal device, wherein the cell-specific high-layer signaling includes the common configuration. The network device may send device-specific high-layer signaling to the terminal device, wherein the device-specific high-layer signaling includes the dedicated configuration.

[0121] [Corrected 05.09.2024 according to Rule 91] In another non-limiting embodiment, the first configuration information includes a first set of frequency domain resource units whose duplex type is uplink, and a second set of frequency domain resource units whose duplex type is downlink.

[0122] In this embodiment, frequency domain resource units with uplink and downlink duplex types are configured independently.

[0123] Furthermore, the duplex type of the overlapping frequency domain resource units in the first frequency domain resource unit set and the second frequency domain resource unit set is full duplex. It should be noted that when the duplex type is full duplex, the method for further distinguishing between TDD and simultaneous co-frequency full duplex can refer to the aforementioned method 1 and method 2, which will not be repeated here.

[0124] In a non-limiting embodiment, the fourth configuration information may be carried in higher-layer signaling, which may specifically be RRC signaling, Media Access Control (MAC) signaling, broadcast signaling, and the like.

[0125] In a specific embodiment, the duplex type of the time-frequency resource unit is configured using a first matrix and a second matrix, wherein each first element in the first matrix indicates whether the duplex type is uplink or flexible, each second element in the second matrix indicates whether the duplex type is downlink or flexible, and each first element or second element corresponds to one time-frequency resource unit.

[0126] Furthermore, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit is full duplex. Correspondingly, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is flexible, the duplex type of the time-frequency resource unit is uplink. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is flexible and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit is downlink.

[0127] In a non-limiting embodiment, in order to save signaling overhead, multiple resource units may be configured to reuse at least one duplex configuration. Specifically, the at least one duplex configuration may be indicated through higher layer signaling.

[0128] In one non-limiting embodiment, the consecutive resource units have the same duplex configuration.

[0129] For example, referring to Figure 7 , consecutive subframes 0 to 2 have the same duplex configuration. Consecutive subbands 3 to 4 have the same downlink duplex type. Consecutive subbands n to n+2 have the same full-duplex type. Consecutive subbands m to n+3 have the same uplink duplex type.

[0130] In one non-limiting embodiment, the higher layer signaling includes identification of multiple duplex configurations and their associated resource units.

[0131] The duplex configuration referred to in this embodiment may be a set of multiple duplex types, such as {D, D, D, D+U, D+U, U, U}.

[0132] For example, high-layer signaling includes three duplex configurations: duplex configuration 1, duplex configuration 2, and duplex configuration 3. Each duplex configuration may correspond to one or more time slots. For example, the subbands associated with duplex configuration 1 include time slot 0, time slot 3, time slot 5, and time slot 7; the time slots associated with duplex configuration 2 include time slot 2, time slot 4, and time slot 6; and the time slots associated with duplex configuration 3 include time slot 1. The duplex configurations may be associated with time slots having the same duplex configuration via a bitmap, where each bit in the bitmap corresponds to a time slot. When the bit is 1, the time slot is associated with the duplex configuration, and when the bit is 0, the time slot is not associated with the duplex configuration. Alternatively, when the bit is 0, the time slot is associated with the duplex configuration, and when the bit is 1, the time slot is not associated with the duplex configuration. Alternatively, the duplex configuration may be associated with the duplex configuration, and when the bit is 1, the time slot is not associated with the duplex configuration. Alternatively, the duplex configuration may be associated with the duplex configuration, and when the bit is 0 ... the time slot index number may be used to indicate all time slots having the same duplex configuration.

[0133] In a non-limiting embodiment, the high-layer signaling includes a first matrix and / or a second matrix for the target time-frequency resources, each first element in the first matrix indicates that the duplex type is uplink or flexible, each second element in the second matrix indicates that the duplex type is downlink or flexible, and each first element or second element corresponds to a time-frequency resource unit.

[0134] In this embodiment, the sizes of the first matrix and the second matrix may be pre-specified by a standard, or pre-agreed upon by the terminal device and the network device. The first matrix and the second matrix may be periodically repeated over the entire time-frequency resource.

[0135] Specifically, the time-frequency resources with flexible duplex type can refer to the definition of flexible symbols in the prior art. The time-frequency resources with flexible duplex type can continue to be configured as uplink, downlink or full duplex.

[0136] Specifically, the first matrix is Among them, 1 indicates that the duplex type is uplink, and 0 indicates that the duplex type is flexible or undetermined. The duplex type on the time-frequency resource corresponding to the first matrix is ​​shown as a1 in Figure 8, where U in the rectangular area indicates that the duplex type is uplink, and an empty rectangular area indicates that the duplex type is flexible. The second matrix is 1 indicates the duplex type is downlink, and 0 indicates the duplex type is flexible or undetermined. The duplex type on the time-frequency resource corresponding to the second matrix is ​​shown in a2 of FIG8 , where D in the rectangular area indicates the duplex type is downlink, and an empty rectangular area indicates the duplex type is flexible.

[0137] Furthermore, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit may be full-duplex. Correspondingly, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is flexible, the duplex type of the time-frequency resource unit may be uplink. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is flexible and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit may be downlink. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is undetermined and the second element indicates that the duplex type is undetermined, the duplex type of the time-frequency resource unit may be flexible.

[0138] As shown in a3 in FIG8 , D+U in the rectangular area indicates that the duplex type is full duplex, and F in the rectangular area indicates that the duplex type is flexible.

[0139] Furthermore, the high-layer signaling may further include a third matrix for the target time-frequency resources, wherein each third element in the third matrix indicates whether the duplex type is full duplex or flexible. In this embodiment, the third matrix may be repeated periodically in the time domain.

[0140] In this embodiment, the high-layer signaling may include a first matrix, a second matrix, and a third matrix.

[0141] Specifically, the third matrix is 1 indicates full duplex, and 0 indicates non-full duplex. Non-full duplex can be downlink, uplink, or flexible. The third matrix can also be used in TDD or FDD communication systems, indicating which time-frequency resources in a TDD or FDD system can be used for full duplex.

[0142] In one variation, the higher layer signaling may include TDD configuration and the third matrix.

[0143] In another variation, the higher layer signaling may include FDD configuration and the third matrix.
