Description

Technical Field

[0001] 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

[0002] There are two features that may appear in the future sixth generation mobile communication technology systems (6th generation mobile networks or 6th generation wireless systems, 6G). One feature is the use of multiple discontinuous bandwidths, and the other is the introduction of simultaneous same-frequency full-duplex technology.

[0003] The use of multiple discontinuous bandwidths is because 6G will pursue higher data transmission rates, which will inevitably require higher transmission bandwidths. However, the spectrum resources controlled by various operators are not necessarily continuous, and may be multiple fragmented bandwidth resources. The emergence of simultaneous full-duplex technology is because simultaneous full-duplex can greatly improve the utilization efficiency of time and frequency resources, and ideally can even double the effect.

[0004] However, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in non-continuous spectrum scenarios. Summary of the invention

[0047] 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 wireless (NR) systems, and future evolution systems or multiple communication fusion 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 architectures, dual-connection architectures, vehicle-to-everything communication architectures, and other architectures.

[0048] This application mainly relates to the communication between terminal equipment and network equipment. Among them:

[0049] The network device in the embodiment of the present application may also be referred to as an access network device, for example, it may be a base station (BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the equipment that provides base station functions includes the base transceiver station (BTS), in the third-generation (3G) network, the equipment that provides base station functions includes the node B (NodeB), and in the fourth-generation (4G) network, the equipment that provides base station functions includes the evolved node B (eNB). In wireless local area networks (WLAN), the equipment that provides base station functions is the access point (AP), and the equipment that provides base station functions in NR is the next generation Node Base station (gNB), as well as the evolved node B (ng-eNB), where 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 (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0050] 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 (Mobile Station, 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 function, 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 evolving Public Land Mobile Network (PLMN), etc., which is not limited in the embodiments of the present application. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0051] As described in the background technology, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in a non-continuous spectrum scenario.

[0052] 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 the types of base stations deployed by different operators and the differences in the duplex types supported by the terminal devices themselves, there can be different arrangements and combinations.

[0053] When one side uses the same frequency and full-duplex type, the combined duplex type on the network side and the terminal device side can be divided into the following five categories:

[0054] 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 duplex (FDD) or time division duplex (TDD).

[0055] Category 2: simultaneous same-frequency full-duplex on the network side and sub-band half-duplex on the terminal equipment side.

[0056] Category 3: simultaneous same-frequency full-duplex on the network side and simultaneous same-frequency full-duplex 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 time and frequency.

[0058] Category 5: sub-band full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal side.

[0059] The scenarios described in categories 3 and 4 may be that the terminal device is roaming, and 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.

[0060] 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.

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

[0062] 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.

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

[0064] Step 101: The 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, 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 pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0067] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0068] In one 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 may be any implementable time unit such as a radio frame, a subframe, a time slot, a symbol, etc., and the present application does not impose any limitation on this.

[0070] In this embodiment, the configuration of the duplex type on the time domain resources can be implemented through the first configuration information. In order to implement simultaneous and same-frequency full-duplex, the terminal device also needs to know the configuration of the duplex type on the frequency domain resources.

[0071] In order to achieve the above purpose, the duplex type can be configured independently for each frequency domain resource unit. In a specific implementation, the duplex type can be configured for each time domain resource unit on one or more frequency domain resources through the first configuration information, and the duplex type can be configured for each frequency domain resource unit in the one or more frequency domain resources one by one.

[0072] 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.

[0073] For example, the terminal device may learn the duplex type on the time domain resources corresponding to one or more sub-bands according to the first configuration information. The duplex type on one or more sub-bands may be obtained through other configuration information.

[0074] 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 the present application does not impose any restrictions on this.

[0075] In another specific implementation manner, the duplex type of each frequency domain resource unit may be configured first, and then on this basis, the time domain resource unit whose duplex type is full-duplex may be additionally indicated.

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

[0077] 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.

[0078] Please refer to Figure 2, 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. Among them, 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 applicable to other embodiments of the present invention.

[0079] Taking the time domain resource unit as time slot as an example, Figure 2 In the duplex configuration shown in 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. Figure 2 The time slot configuration shown in a is a basic configuration pattern, that is, D, X, D+U and U are used as a basic pattern, and then they appear periodically and repeatedly 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. Figure 2 The time slot configuration shown in b is a basic configuration pattern, that is, D, X, U, and D+U are used as a basic pattern, and then they appear periodically and repeatedly in the time domain.

[0081] exist Figure 2 In the duplex configuration shown in c, the duplex type of time slots 0 to 3 is downlink, the duplex type of time slot 4 is full duplex, the duplex type of time slots 6 to 8 is flexible, and the duplex type of time slots 9 to 13 is uplink. Figure 2 The time slot configuration shown in c is a basic configuration pattern, that is, D, D+U, X and U are used as a basic pattern, and then they are repeated periodically in the time domain.

[0082] Optionally, other basic patterns may also be other possible 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 the time domain resource units with duplex types of uplink, downlink, and flexible, and the relative positions of the time domain resource units with duplex type of full duplex in the time domain resource units with duplex type of flexible.

[0083] In this embodiment, the time domain resource unit with a duplex type of full duplex is nested in the time domain resource of other types. Therefore, the first configuration information includes the relative position of the time domain resource with a duplex type of full duplex and the absolute position of the time domain resource unit of other duplex types. The absolute position can be calculated from the starting time domain position and / or the ending time domain position and / or the time domain duration of the full duplex time domain resource.

[0084] Taking the time domain resource unit as time slot as an example, Figure 3 In the duplex configuration shown in a, the time slot whose duplex type is full-duplex is nested in the time domain resource unit whose duplex type is flexible.

[0085] exist Figure 3 In the duplex configuration shown in b, the time slot whose duplex type is full-duplex is nested in the time domain resource unit whose duplex type is downlink.

[0086] exist Figure 3 In the duplex configuration shown in c, the time slot whose duplex type is full-duplex is nested in the time domain resource unit whose duplex type is uplink.

[0087] In a non-limiting embodiment, the terminal device may receive fourth configuration information, the fourth configuration information including 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.

[0088] The embodiment of the present invention introduces limited time domain resource units to perform simultaneous and same-frequency full-duplex transmission on the basis of frequency division duplex (FDD).

[0089] Please refer to Figure 4 , FDD is configured on subband 1 to subband 4, wherein the duplex type on subband 1 and subband 2 is downlink, and the duplex type on subband 3 and subband 4 is uplink.

[0090] On the basis of the above FDD, the corresponding duplex type is configured on subframe 0 to subframe 4. Specifically, the duplex type is configured as full duplex on symbols 4 to 9 of subframe 0 corresponding to subband 2, and all symbols of subframe 2. At this time, the first time domain resource unit is symbol 4 to symbol 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 corresponding to subband 4. At this time, the first time domain resource unit is symbols 9 to 13 of subframe 0 and all symbols of subframe 1.

[0092] Furthermore, the first configuration information in the embodiment of the present invention may be repeated periodically. For example, Figure 4 It is shown in FIG. 1 that the first configuration information includes duplex configuration on 5 subframes (ie, 5 ms), and the repetition period can be set to 5 ms, so in each of the subsequent 5 subframes, Figure 4 The duplex configurations on the 5 subframes shown are consistent.

[0093] In a specific embodiment, the terminal device may receive a bitmap, each bit in the bitmap corresponds to each 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.

[0094] 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.

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

[0096] Specifically, the position of the first time domain resource unit may 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.

[0097] 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.

[0098] In the embodiment of the present invention, the time domain resource unit has an initial duplex type, which may be full duplex, and may be configured through the first configuration information. The third configuration information may include the position of the second time domain resource unit whose duplex type is uplink and / or the position of the third time domain resource unit whose duplex type is downlink, thereby completing the complete duplex configuration on each time domain resource.

[0099] More specifically, the third configuration information may be in the form of a bitmap, where the bit value is a target value indicating the duplex type is uplink or the duplex type is downlink. For example, the target value is 1. The duplex type is uplink and the duplex type is downlink using different bitmaps for configuration.

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

[0101] In a variation, the duplex type of each time domain resource unit is first configured as uplink through the first configuration information. Then the position of the time domain resource with the duplex type of full duplex and / or the position of the time domain resource with the duplex type of downlink may be included in the third configuration information, thereby completing the complete duplex configuration on each time domain resource. The position of the time domain resource may be calculated from the starting time domain position and / or the ending time domain position and / or the 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 through the first configuration information. Then the position of the time domain resource with the duplex type of full duplex and / or the position of the time domain resource with the duplex type of uplink may be included in the third configuration information, thereby completing the complete duplex configuration on each time domain resource. The position of the time domain resource may be calculated from the starting time domain position and / or the ending time domain position and / or the time domain duration of the time domain resource.

[0103] Furthermore, the third configuration information in the embodiment of the present invention may be cyclically cycled. The specific cycle size and / or cycle offset value may be pre-agreed by the network device and the terminal device, or may be specified by the communication standard protocol or configured by the network side through high-level signaling (such as RRC) or dynamic signaling (such as DCI), and this application does not limit this.

[0104] In a non-limiting embodiment, the present application also discloses a communication method, for details, please refer to Figure 6 The method may further include step 601: the network device sends fourth configuration information to the terminal device, wherein the fourth configuration information is used to indicate the duplex type on each frequency domain resource unit. Accordingly, the terminal device receives the fourth configuration information.

[0105] 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.

[0106] Specifically, on some sub-bands with bandwidths less than the preset bandwidth, the network side can adopt a simultaneous same-frequency full-duplex configuration. On the contrary, on some sub-bands with bandwidths greater than or equal to the preset bandwidth, the network side can adopt a traditional half-duplex (i.e., only downlink or only uplink) configuration. This is because full-duplex has high requirements for anti-interference capability, and the magnitude of anti-interference capability is inversely proportional to the sub-band bandwidth. Therefore, in order to ensure the quality of communication, the network side can adopt a simultaneous same-frequency full-duplex configuration on sub-bands with bandwidths less than the preset bandwidth. Among them, the preset bandwidth can be determined in a predefined manner, or the value of the preset bandwidth can be determined according to the full-duplex capability of the network side device or the terminal device.

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

[0108] In a non-limiting embodiment, the network device may inform the terminal device of its capabilities through 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 that the network device supports simultaneous full-duplex on the same frequency.

[0109] In a non-limiting embodiment, the terminal device may also consider informing the network device of its capability through high-layer signaling by reporting the capability. Specifically, the capability of the terminal device includes the bandwidth / frequency / sub-band that the network device supports for simultaneous full-duplex operation on the same frequency.

[0110] Furthermore, when reporting its capabilities, the terminal device can also report the type of device. For a terminal device that supports simultaneous full-duplex, its device type is different from other terminal devices that support half-duplex or terminal devices that support SBFD, that is, the terminal device that supports simultaneous full-duplex has a new device type. The new device type of the terminal device can be considered as an enhancement of TDD / FDD, or an enhancement of SBFD.

[0111] 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 limitation 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 may include simultaneous same-frequency full-duplex and time-division duplex. Then, when the terminal device learns through 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.

[0114] 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.

[0115] For example, the second configuration information occupies one bit, and when the value of the bit is 1, it indicates that the duplex type is simultaneous frequency full duplex; when the value of the bit is 0, it indicates that the duplex type is time division duplex. The reverse is also applicable, when the value of the bit is 0, it indicates that the duplex type is simultaneous frequency full duplex; when the value of the bit is 1, it indicates that the duplex type is TDD.

[0116] Mode 2: The terminal device distinguishes based on the time division duplex configured in the time domain of the first frequency domain resource unit. For example, whether the 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 same-frequency full-duplex.

[0117] For a terminal device, it can obtain the duplex configuration of all subbands, or only obtain the duplex configuration of the subband in which it is located. 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 common configuration on multiple frequency domain resource units and a dedicated configuration for a target frequency domain resource unit, and the dedicated configuration includes full duplex. Specifically, the network device may send a cell-specific high-level signaling to the terminal device, and the cell-specific high-level signaling includes the common configuration. The network device may send a device-specific high-level signaling to the terminal device, and the device-specific high-level signaling includes a dedicated configuration.

[0119] 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.

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

[0121] 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 TDD from simultaneous co-frequency full duplex can refer to the aforementioned method 1 and method 2, which will not be repeated here.

[0122] In a non-limiting embodiment, the fourth configuration information may be carried in a high-layer signaling, which may specifically be an RRC signaling, a Media Access Control (MAC) signaling, a broadcast signaling, and the like.

[0123] In a specific embodiment, the duplex type is configured for the time-frequency resource unit through a first matrix and a second matrix, wherein 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.

[0124] Further, 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.

[0125] 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, at least one duplex configuration may be indicated through high-layer signaling.

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

[0127] For example, see Figure 7 , consecutive subframes 0 to 2 have the same duplex configuration. Consecutive subbands 3 to 4 have the same duplex type downlink. Consecutive subbands n to n+2 have the same duplex type full duplex. Consecutive subbands m to n+3 have the same duplex type uplink.

[0128] In one non-limiting embodiment, the higher layer signaling includes identification of multiple duplex configurations and their associated resource units.

[0129] 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}.

[0130] For example, the high-level 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 configuration may be associated with time slots having the same duplex configuration in a bitmap manner, wherein each bit in the bitmap may correspond to one time slot, and when the bit is 1, it represents that the time slot is associated with the duplex configuration, and when the bit is 0, it represents that the time slot is not associated with the duplex configuration, or, when the bit is 0, it represents that the time slot is associated with the duplex configuration, and when the bit is 1, it represents that the time slot is not associated with the duplex configuration; or, by indicating the time slot index number of all time slots having the same duplex configuration.

[0131] In a non-limiting embodiment, high-layer signaling includes a first matrix and / or a second matrix for 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.

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

[0133] Specifically, the time-frequency resources with a flexible duplex type may refer to the definition of flexible symbols in the prior art. The time-frequency resources with a flexible duplex type may continue to be configured as uplink, downlink or full-duplex.

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

[0135] Further, 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.

[0136] like Figure 8 As shown in a3, 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.

[0137] Furthermore, the high-layer signaling may further include a third matrix for the target time-frequency resources, and each third element in the third matrix indicates that the duplex type is full duplex or flexible. In this embodiment, the third matrix may be repeated periodically in the time domain.

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

[0139] Specifically, the third matrix is Among them, 1 indicates that the duplex type is full duplex, and 0 indicates that the duplex type is non-full duplex. Among them, the non-full duplex can be downlink or uplink or flexible. The third matrix can also act on the communication system that is originally TDD or FDD, that is, it can indicate which time-frequency resources in the TDD or FDD system can be used as full duplex.

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

[0141] In another variation, the higher layer signaling may include the configuration of FDD and the third matrix.
