Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus, and a computer-readable storage medium. Background Technology

[0002] The future sixth-generation mobile communication technology system (6G) may have two features: one is the use of multiple discontinuous bandwidths, and the other is the introduction of simultaneous full-duplex technology.

[0003] The use of multiple discontinuous bandwidths is due to the fact that 6G will pursue higher data transmission rates, which inevitably requires higher transmission bandwidth. Furthermore, the spectrum resources held by different operators are not necessarily continuous, but may consist of multiple fragmented bandwidth resources. Simultaneously, the emergence of co-frequency full-duplex technology is because co-frequency full-duplex can greatly improve the utilization efficiency of time and frequency resources, ideally even doubling the effect.

[0004] However, there is currently no corresponding solution for resource indication methods for simultaneous duplexing on the same frequency in discontinuous spectrum scenarios. Summary of the Invention

[0032] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0047] The communication systems applicable to the embodiments of this application include, but are not limited to, Long Term Evolution (LTE) systems, 5th-generation (5G) systems, New Radio (NR) systems, and future evolution systems or multiple converged communication systems. The 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solutions of this application are also applicable to different network architectures, including but not limited to relay network architectures, dual-connectivity architectures, and vehicle-to-everything (V2X) communication architectures.

[0048] This application primarily relates to communication between terminal devices and network devices. Specifically:

[0049] The network device in this application embodiment can also be called an access network device, for example, it can be a base station (BS) (also called a base station device). A network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in second-generation (2G) networks, the equipment providing base station functionality includes base transceiver stations (BTS); in third-generation (3G) networks, the equipment providing base station functionality includes nodes (NodeB); in fourth-generation (4G) networks, the equipment providing base station functionality includes evolved nodes (eNB); in wireless local area networks (WLANs), the equipment providing base station functionality is the access point (AP); in NR, the equipment providing base station functionality includes next-generation node base stations (gNBs) and further evolved nodes (ng-eNBs). gNBs and terminal devices communicate using NR technology, while ng-eNBs and terminal devices communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network devices in this application embodiment also include devices that provide base station functions in future new communication systems.

[0050] In this application, "terminal equipment" can 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 equipment, user agents, or user devices. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application does not limit the scope of these terms. Terminal equipment can also be referred to as User Equipment (UE), terminal, etc.

[0051] As described in the background section, there is currently no corresponding solution for resource indication methods for simultaneous duplexing at the same frequency in discontinuous spectrum scenarios.

[0052] The following is a judgment on the future evolution of full-duplex technology: the overall trend is divided into 4 stages. Considering the differences in the types of base stations deployed by different operators and the differences in the duplex types supported by the terminal equipment itself, there can be different permutations and combinations.

[0053] When one side uses the same frequency and full-duplex type simultaneously, the combined duplex type of the network side and the terminal equipment side can be divided into the following 5 categories:

[0054] Category 1 includes simultaneous full-duplex operation on the same frequency on the network side and half-duplex operation on the terminal device side, such as Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD).

[0055] Category 2: Simultaneous full-duplex operation on the network side and half-duplex operation on the terminal device side.

[0056] Category 3: Simultaneous full-duplex operation on the network side and on the terminal device side.

[0057] Category 4: half-duplex on the network side and full-duplex on the terminal device side at the same frequency.

[0058] Category 5: Network-side sub-band full-duplex, and terminal-side devices simultaneously operating on the same frequency in full-duplex mode.

[0059] The scenarios described in categories 3 and 4 can involve roaming terminal devices, such as an advanced terminal device roaming to a relatively outdated mobile network. The technical solution of this application can be used in any of the above five scenarios.

[0060] The technical solution of this application configures the duplex type on the time domain resource unit through the first configuration information, and improves the communication quality by introducing a new duplex type, full duplex, to achieve full duplex transmission on the entire discontinuous spectrum.

[0061] The configuration or configuration information mentioned in this invention can be indicated by the network layer through higher-layer signaling (such as RRC) or through dynamic signaling indication (such as DCI).

[0062] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0063] See Figure 1 The method provided in this application specifically includes the following steps:

[0064] Step 101: The network device sends first configuration information, which indicates the duplex type for each time-domain resource unit, including full-duplex. Correspondingly, the terminal device receives the first configuration information.

[0065] 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.

[0066] It should be noted that the sequence number of each step in this embodiment does not represent a limitation on the execution order of each step.

[0067] It is understood that, in specific implementations, the communication method can be implemented using software programs, which run within a processor integrated into the chip or chip module. The method can also be implemented using a combination of software and hardware; this application does not impose any limitations on this approach.

[0068] In a non-limiting embodiment, the duplex type is selected from uplink, downlink, and full-duplex.

[0069] In a non-limiting embodiment, the time-domain resource unit can be any implementable time unit such as a radio frame, subframe, time slot, or symbol, and this application does not impose any restrictions on it.

[0070] In this embodiment, the first configuration information enables the configuration of duplex type in the time domain. To achieve simultaneous full-duplex on the same frequency, the terminal device also needs to know the duplex type configuration in the frequency domain.

[0071] To achieve the above objectives, an independent duplex type configuration can be performed for each frequency domain resource unit. In one specific implementation, duplex type configuration can be performed for each time domain resource unit on one or more frequency domain resources using first configuration information, and the duplex type configuration can be performed for each frequency domain resource unit in the one or more frequency domain resources individually.

[0072] Specifically, the unit of frequency domain resources can be the size of the frequency domain resources occupied by a resource block (RB), the size of the frequency domain resources occupied by a resource element (RE), the size of the frequency domain resources occupied by an integer multiple of an RB, the size of the frequency domain resources occupied by an integer multiple of an RE, or a sub-band, etc.

[0073] For example, the terminal device can determine 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 one or more sub-bands can then be obtained through other configuration information.

[0074] It should be noted that the first configuration information for duplex type of time domain resources and other configuration information for duplex type of frequency domain resources may be included in the same higher-layer signaling or in different higher-layer signaling; this application does not impose any restrictions on this.

[0075] In another specific implementation, the duplex type of each frequency domain resource unit can be configured first, and then, based on this, the time domain resource units with the duplex type of full duplex can be additionally indicated.

[0076] In a non-limiting embodiment, the first configuration information includes the duplex type as uplink (also known as half-duplex uplink), downlink (also known as half-duplex downlink), full-duplex, and the location of flexible time-domain resource units.

[0077] In this embodiment, the various duplex types are independent of each other. Specifically, the first configuration information may include the absolute position of the time-domain resource unit for each duplex type, for example, the absolute position is the starting position and offset of the time-domain resource unit.

[0078] Please refer to the details. Figure 2In this context, D indicates downlink duplex, U indicates downlink duplex, X indicates flexible duplex (corresponding to flexible resources in existing communication systems), and D+U indicates full-duplex duplex. D, U, X, and D+U can specifically include one or more identical time-domain resource units, or they can specifically include one or more time-domain resource units of different types. For example, D, U, X, and D+U can include one or more time slots, and optionally, one or more symbols. Alternatively, D, U, X, and D+U can include one or more symbols. The above explanation can also be applied to other embodiments of the present invention.

[0079] Taking time-domain resource units as time slots as an example, in Figure 2 In the duplex configuration shown in diagram a, the duplex type on time slots 0 to 3 is downlink, the duplex type on time slots 4 to 6 is flexible, the duplex type on time slots 7 and 8 is full-duplex, and the duplex type on time slots 9 to 13 is uplink. Among these, it can be... Figure 2 The time slot configuration shown in a is a basic configuration pattern, that is, D, X, D+U and U are a basic pattern, and then it appears periodically in the time domain.

[0080] exist Figure 2 In the duplex configuration shown in b, the duplex type on time slots 0 to 3 is downlink, the duplex type on time slots 4 to 8 is flexible, the duplex type on time slots 9 and 10 is full-duplex, and the duplex type on time slots 11 to 13 is uplink. Among these, it can be... Figure 2 b shows a time slot configuration as a basic configuration pattern, that is, using D, X, U, and D+U as a basic pattern, which then appears periodically in the time domain.

[0081] exist Figure 2 In the duplex configuration shown in c, the duplex type on time slots 0 to 3 is downlink, the duplex type on time slot 4 is full-duplex, the duplex type on time slots 6 to 8 is flexible, and the duplex type on time slots 9 to 13 is uplink. Among these, it can be... Figure 2 c displays a time slot configuration as a basic configuration pattern, namely, D, D+U, X, and U as a basic pattern, which then appears periodically in the time domain.

[0082] Optionally, other basic patterns may also be other permutations and combinations of D, U, X, and D+U, which are not limited in this invention. In another non-limiting embodiment, the first configuration information includes the absolute position of time-domain resource units with duplex type uplink, downlink, and flexible, and the relative position of time-domain resource units with duplex type full-duplex within time-domain resource units with flexible duplex type.

[0083] In this embodiment, time-domain resource units of full-duplex type are nested within other types of time-domain resources. Therefore, the first configuration information includes the relative position of the full-duplex time-domain resource and the absolute position of the other time-domain resource units of different duplex types. The absolute position can be calculated from the start and / or end time-domain position and / or time-domain duration of the full-duplex time-domain resource.

[0084] Taking time-domain resource units as time slots as an example, in Figure 3 In the duplex configuration shown in a, time slots of full-duplex type are nested within time-domain resource units of flexible duplex type.

[0085] exist Figure 3 In the duplex configuration shown in b, time slots of full-duplex type are nested within time-domain resource units of downlink type.

[0086] exist Figure 3 In the duplex configuration shown in c, time slots of full-duplex type are nested within time domain resource units of uplink type.

[0087] In a non-limiting embodiment, the terminal device may receive fourth configuration information, which includes the location of a first frequency domain resource unit with a duplex type of uplink and a second frequency domain resource unit with a duplex type of downlink, wherein the first configuration information includes the location of a first time domain resource unit with a duplex type of full-duplex corresponding to the first frequency domain resource unit and / or the second frequency domain resource unit.

[0088] The embodiments of the present invention are based on Frequency Division Duplexing (FDD), and introduce a limited number of time-domain resource units for simultaneous full-duplex transmission at the same frequency.

[0089] Please refer to the details. Figure 4 FDD is configured on sub-bands 1 to 4, where the duplex type on sub-bands 1 and 2 is downlink, and the duplex type on sub-bands 3 and 4 is uplink.

[0090] Based on the aforementioned FDD, corresponding duplex types are configured on subframes 0 to 4. Specifically, the duplex type is configured as full-duplex on symbols 4 to 9 of subframe 0 and all symbols of subframe 2 in subband 2. At this time, the first temporal resource unit is symbols 4 to 9 of subframe 0 and all symbols of subframe 2.

[0091] The duplex type is configured as full-duplex on symbols 9 to 13 of subframe 0 and all symbols of subframe 1 in subband 4. At this time, the first temporal resource unit is symbols 9 to 13 of subframe 0 and all symbols of subframe 1.

[0092] Furthermore, the first configuration information in this embodiment of the invention can be repeated periodically. For example, Figure 4 The first configuration information shows that it includes duplex configuration over 5 subframes (i.e., 5ms). The repetition period can be set to 5ms, so in every subsequent 5 subframes, it is consistent with... Figure 4 The duplex configurations on the five subframes shown are consistent.

[0093] In one specific embodiment, the terminal device can receive a bitmap, where each bit in the bitmap corresponds to a time-domain resource unit, and each bit indicates whether the duplex type is full-duplex. The bitmap can be periodically cyclical in the time domain.

[0094] For example, the bitmap is 11001, which corresponds to the duplex configuration on 5 subframes. Here, 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.

[0095] In another specific embodiment, the terminal device receives higher-layer signaling, which includes the location of the first time-domain resource unit.

[0096] Specifically, the location of the first time-domain resource unit can be carried in the downlink control information (DCI). This allows for dynamic configuration of time-domain resources with full-duplex duplex type, providing greater flexibility.

[0097] In a non-limiting embodiment, the duplex type of each time-domain resource unit can first be configured to full-duplex using first configuration information. Then, the location of the second time-domain resource unit with an uplink duplex type and / or the location of the third time-domain resource unit with a downlink duplex type can be configured using third configuration information.

[0098] In this embodiment of the invention, the time-domain resource unit has an initial duplex type, which can be full-duplex, and can be configured through the first configuration information. The third configuration information can include the position of the second time-domain resource unit with an uplink duplex type and / or the position of the third time-domain resource unit with a downlink duplex type, thereby completing the full duplex configuration for each time-domain resource.

[0099] More specifically, the third configuration information can be in the form of a bitmap, where the bit value is a target value indicating whether the duplex type is uplink or downlink. For example, the target value is 1. Uplink and downlink duplex types are configured using different bitmaps.

[0100] Please refer to the details. Figure 5 ,like Figure 5 As shown, the duplex type on all eight symbols is full-duplex D+U. The second time-domain resource unit for uplink duplex type is the 5th symbol, and the corresponding bitmap is 00001000. Similarly, the third time-domain resource units for downlink duplex type are the 2nd, 4th, 6th, and 8th symbols, and the corresponding bitmap is 01010101. The bitmap can be periodically cycled in the time domain.

[0101] In one variation, the duplex type of each time-domain resource unit is first configured as uplink using the first configuration information. Then, the third configuration information can include the location of time-domain resources with full-duplex type and / or the location of time-domain resources with downlink type, thereby completing the full duplex configuration for each time-domain resource. The location of the time-domain resource can be calculated from the start time-domain location and / or end time-domain location and / or time-domain duration of the time-domain resource.

[0102] In another variation, the duplex type of each time-domain resource unit is first configured as downlink using the first configuration information. Then, the third configuration information can include the location of time-domain resources with full-duplex type and / or the location of time-domain resources with uplink type, thereby completing the full duplex configuration for each time-domain resource. The location of the time-domain resource can be calculated from the start and / or end time-domain positions and / or the duration of the time-domain resource.

[0103] Furthermore, the third configuration information in this embodiment of the invention can be periodically cycled. The specific cycle size and / or cycle offset value can be pre-agreed by the network device and the terminal device, or specified by the communication standard protocol, or configured by the network side through higher-layer signaling (such as RRC) or dynamic signaling (such as DCI). This application does not impose any restrictions on this.

[0104] In a non-limiting embodiment, this application also discloses a communication method, which can be found in the following details. Figure 6 The method may further include step 601: the network device sends fourth configuration information to the terminal device, the fourth configuration information indicating the duplex type on each frequency domain resource unit. Accordingly, the terminal device receives the fourth configuration information.

[0105] In this embodiment, duplex configuration of time-domain resources is achieved through the first configuration information, and duplex configuration of frequency-domain resources is achieved through the fourth configuration information. The duplex configuration scheme for frequency-domain resources will be described in detail below.

[0106] Specifically, on subbands with bandwidths less than a preset bandwidth, the network side can adopt a simultaneous, same-frequency, full-duplex configuration. Conversely, on subbands with bandwidths 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 requires higher anti-interference capabilities, and the anti-interference capability is inversely proportional to the subband bandwidth. Therefore, to ensure communication quality, the network side can adopt a simultaneous, same-frequency, full-duplex configuration on subbands with bandwidths less than the preset bandwidth. The preset bandwidth can be determined through a predefined method or based on the full-duplex capability of the network-side device or terminal device.

[0107] Similarly, on the terminal device side, on some subbands with bandwidth less than the preset bandwidth, the terminal device can adopt a simultaneous full-duplex configuration on the same frequency, while on some subbands with bandwidth greater than or equal to the preset bandwidth, the terminal device can adopt a traditional half-duplex configuration.

[0108] 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 network device's capabilities include support for simultaneous full-duplex bandwidth and / or center frequency and / or subbands.

[0109] In a non-limiting embodiment, the terminal device may also inform the network device of its capabilities via higher-layer signaling through a capability reporting mechanism. Specifically, the terminal device's capabilities include the network device's support for simultaneous full-duplex bandwidth / frequency / subband operation.

[0110] Furthermore, when reporting its capabilities, the terminal device can also report its device type. For terminal devices supporting simultaneous full-duplex on the same frequency, its device type differs from other terminal devices supporting half-duplex or SBFD; that is, terminal devices supporting simultaneous full-duplex on the same frequency have a new device type. This new device type can be considered an enhancement of TDD / FDD or an enhancement of SBFD.

[0111] It should be noted that the new device type of the aforementioned terminal equipment can be any other implementable name and can be specified in the communication standard protocol; this application does not impose any restrictions on this.

[0112] In a non-limiting embodiment, the duplex type on the frequency domain resource unit is selected from uplink, downlink, and full-duplex.

[0113] Specifically, full-duplex can include simultaneous full-duplex on the same frequency and time-division full-duplex. Therefore, if the terminal device learns from the first configuration information that the full-duplex type is full-duplex, it still needs to further distinguish between simultaneous full-duplex on the same frequency and time-division full-duplex.

[0114] Method 1: The terminal device receives a third configuration, which is used to indicate that the duplex type of the first frequency domain resource unit is time-division duplex or simultaneous full-duplex on the same frequency.

[0115] 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 full-duplex; when the value of this bit is 0, it indicates that the duplex type is time-division duplex. The reverse also applies: when the value of this bit is 0, it indicates that the duplex type is simultaneous full-duplex; when the value of this bit is 1, it indicates that the duplex type is TDD.

[0116] Method 2: The terminal device distinguishes between different types of duplex based on the time-domain configuration of the first frequency domain resource unit. For example, whether legacy TDD-DL-UL-SlotConfiguration is configured on the frequency domain resource unit. If yes, it indicates that the duplex type is TDD; otherwise, it indicates that the duplex type is simultaneous full-duplex on the same frequency.

[0117] For a terminal device, it can obtain the duplex configuration of all subbands, or it can obtain only the duplex configuration of the subband it is in. The duplex configuration can be UE-specific configuration information or cell-specific configuration information.

[0118] In a non-limiting embodiment, the fourth configuration information includes a general configuration across multiple frequency domain resource units and a dedicated configuration for a target frequency domain resource unit, wherein the dedicated configuration includes full-duplex. Specifically, the network device can send cell-specific higher-layer signaling to the terminal device, and the cell-specific higher-layer signaling includes the general configuration. The network device can also send device-specific higher-layer signaling to the terminal device, and the device-specific higher-layer signaling includes the dedicated configuration.

[0119] In another non-limiting embodiment, the first configuration information includes a first set of frequency domain resource units with uplink duplex type and a second set of frequency domain resource units with downlink duplex type.

[0120] In this embodiment, frequency domain resource units with duplex types of uplink and downlink are configured independently.

[0121] Furthermore, the duplex type of the frequency domain resource units that overlap in the first and second frequency domain resource unit sets is full-duplex. It should be noted that, when the duplex type is full-duplex, the methods for further distinguishing between TDD and simultaneous full-duplex on the same frequency can refer to the aforementioned methods 1 and 2, and will not be repeated here.

[0122] In a non-limiting embodiment, the fourth configuration information may be carried in higher-layer signaling. Specifically, the higher-layer signaling may be RRC signaling, Media Access Control (MAC) signaling, broadcast signaling, etc.

[0123] In one specific embodiment, the duplex type of time-frequency resource units is configured through a first matrix and a second matrix. Each first element in the first matrix represents a duplex type of uplink or flexible, and each second element in the second matrix represents a duplex type of downlink or flexible. Each first or second element corresponds to one time-frequency resource unit.

[0124] Furthermore, if the first element representing the duplex type for the same time-frequency resource unit is uplink and the second element representing the duplex type is downlink, then the duplex type of that time-frequency resource unit is full-duplex. Correspondingly, if the first element representing the duplex type for the same time-frequency resource unit is uplink and the second element representing the duplex type is flexible, then the duplex type of that time-frequency resource unit is uplink. If the first element representing the duplex type for the same time-frequency resource unit is flexible and the second element representing the duplex type is downlink, then the duplex type of that time-frequency resource unit is downlink.

[0125] In a non-limiting embodiment, to save signaling overhead, multiple resource units can be configured to multiplex at least one duplex configuration. Specifically, at least one duplex configuration can be indicated via higher-layer signaling.

[0126] In a non-limiting embodiment, multiple consecutive resource units have the same duplex configuration.

[0127] For example, please refer to Figure 7 Subframes 0 through 2 have the same duplex configuration. Subbands 3 through 4 have the same downlink duplex type. Subbands n through n+2 have the same full-duplex type. Subbands m through n+3 have the same uplink duplex type.

[0128] In a non-limiting embodiment, higher-level signaling includes multiple duplex configurations and identifiers of their associated resource units.

[0129] The duplex configuration referred to in this embodiment can be a collection of multiple duplex types, such as {D,D,D,D+U,D+U,U,U}.

[0130] For example, higher-layer signaling includes three duplex configurations: duplex configuration 1, duplex configuration 2, and duplex configuration 3. Each duplex configuration can correspond to one or more time slots. For example, the subbands associated with duplex configuration 1 include time slots 0, 3, 5, and 7; the time slots associated with duplex configuration 2 include time slots 2, 4, and 6; and the time slot associated with duplex configuration 3 includes time slot 1. The duplex configurations can be associated with time slots having the same duplex configuration through a bitmap, where each bit in the bitmap corresponds to one time slot. A bit of 1 indicates that the time slot is associated with the duplex configuration, and a bit of 0 indicates that the time slot is not associated with the duplex configuration; or, a bit of 0 indicates that the time slot is associated with the duplex configuration, and a bit of 1 indicates that the time slot is not associated with the duplex configuration; or, the time slot index number of all time slots with the same duplex configuration can be used.

[0131] In a non-limiting embodiment, the higher-layer signaling includes a first matrix and / or a second matrix for a target time-frequency resource, each first element in the first matrix representing a duplex type of uplink or flexible, and each second element in the second matrix representing a duplex type of downlink or flexible, each first or second element corresponding to a time-frequency resource unit.

[0132] In this embodiment, the dimensions of the first matrix and the second matrix can be predetermined by a standard or agreed upon by the terminal device and the network device. The first matrix and the second matrix can be repeated periodically over the entire time-frequency resource.

[0133] Specifically, time-frequency resources with flexible duplex type can refer to the definition of flexible symbol in the prior art. Time-frequency resources with flexible duplex type can be further configured as uplink, downlink, or full-duplex.

[0134] Specifically, the first matrix is Where 1 indicates uplink duplex type, and 0 indicates flexible or undetermined duplex type. The duplex type on the time-frequency resources corresponding to the first matrix is ​​as follows: Figure 8 As shown in a1, within the rectangular area, U indicates up-duplex type, and an empty rectangular area indicates flexible duplex type. The second matrix is... Where 1 indicates downlink duplex type, and 0 indicates flexible or undetermined duplex type. The duplex type on the time-frequency resources corresponding to the second matrix is ​​as follows: Figure 8 As shown in a2, within the rectangular area, D indicates that the duplex type is downlink, and within the rectangular area, an empty area indicates that the duplex type is flexible.

[0135] Furthermore, if the first element representing the duplex type for the same time-frequency resource unit is uplink and the second element representing the duplex type is downlink, then the duplex type of that time-frequency resource unit can be full-duplex. Correspondingly, if the first element representing the duplex type for the same time-frequency resource unit is uplink and the second element representing the duplex type is flexible, then the duplex type of that time-frequency resource unit can be uplink. If the first element representing the duplex type for the same time-frequency resource unit is flexible and the second element representing the duplex type is downlink, then the duplex type of that time-frequency resource unit can be downlink. If the first element representing the duplex type for the same time-frequency resource unit is undetermined and the second element representing the duplex type is undetermined, then the duplex type of that time-frequency resource unit can be flexible.

[0136] like Figure 8 As shown in a3, D+U within the rectangular area indicates full-duplex duplex, and F within the rectangular area indicates flexible duplex duplex.

[0137] Furthermore, the higher-layer signaling may also include a third matrix targeting the target time-frequency resources, where each third element of the third matrix represents a duplex type of full-duplex or flexible. In this embodiment, the third matrix may repeat periodically in the time domain.

[0138] In this embodiment, the higher-layer signaling may include a first matrix, a second matrix, and a third matrix.

[0139] Specifically, the third matrix is In this matrix, 1 indicates full-duplex, and 0 indicates non-full-duplex. The non-full-duplex type can be downlink, uplink, or flexible. The third matrix can also be applied to existing TDD or FDD communication systems, indicating which time-frequency resources within the TDD or FDD system can be used for full-duplex communication.

[0140] In one variation, higher-layer signaling may include TDD configuration and a third matrix.

[0141] In another variation, higher-level signaling may include FDD configuration and a third matrix.
