[0151] DCI format1_0; DCI format1_1; DCI format1_2; DCI format1_3.

[0152] Among them, DCI format0_x is used to schedule the physical uplink control channel (Physical Uplink Shared Channel, PUSCH), and DCI format1_x is used to schedule the physical downlink control channel (Physical Downlink Shared Channel, PDSCH).

[0153] Exemplarily, the first signaling may be a Medium Access Control Element (MAC CE).

[0154] In some embodiments, the first signaling may be group common signaling.

[0155] Exemplarily, the first signaling may be DCI format 2-0, or other group common signaling.

[0156] In the embodiment of the present disclosure, the type of the first signaling is not limited.

[0157] In some embodiments, the content and format of the sub-band resource indication information are not limited.

[0158] Exemplarily, the sub-band resource indication information may be carried in a resource indication field of a unicast DCI.

[0159] Exemplarily, the subband resource indication information may be carried by a MAC CE.

[0160] Exemplarily, the subband resource indication information may be carried via a group-common DCI.

[0161] Step S2102 , the network device 102 sends a second signaling to the terminal 101 .

[0162] In some embodiments, terminal 101 receives the second signaling.

[0163] In some embodiments, the second signaling is used to configure the first value.

[0164] In some embodiments, the first value is the number of time units included in the time window.

[0165] In some embodiments, the second signaling may be semi-static signaling, including but not limited to Radio Resource Control (RRC) signaling or system messages.

[0166] The second signaling may be a system information block n (System Information Blockn, SIBn), where n is a positive integer.

[0167] In some embodiments, the time unit included in the time window can be a time slot, an Orthogonal Frequency Division Multiplexing symbol (OFDM symbol), a span, a Time Division Duplexing (TDD) cycle, a radio frame, etc., which is not limited in this disclosure. A span includes one or more consecutive OFDM symbols in the same time slot.

[0168] In step S2103, the terminal 101 determines a time window.

[0169] In some embodiments, the sub-band resource indication information is valid within the time window.

[0170] In some embodiments, the time window is the valid time domain range of the sub-band resource indication information.

[0171] In some embodiments, the terminal 101 may determine the time window based on a predefined method, including but not limited to a protocol agreement.

[0172] In some embodiments, the terminal 101 may determine a first time point at which the first signaling is received as a starting time point of the time window, and determine a second time point as an ending time point of the time window.

[0173] In an example, the second time point is the time point when the terminal 101 successfully receives the next adjacent first signaling.

[0174] It is understandable that the terminal 101 may determine the time window from the time when the first signaling is received to the time when the terminal 101 successfully receives the next adjacent first signaling.

[0175] In an example, before the second time when the terminal 101 successfully receives the next adjacent first signaling, the terminal 101 may always determine the resources occupied by the sub-band according to the sub-band resource indication information carried in the first signaling.

[0176] Exemplarily, before the second time point, the terminal 101 may determine that the subband occupies the first resource indicated by the subband resource indication information.

[0177] In some embodiments, the terminal 101 may determine that the time window corresponds to a time division duplexing (TDD) period.

[0178] In one example, a TDD cycle is a cycle of sending and / or receiving behavior. In the embodiment of the present disclosure, the terminal 101 may determine that the time window corresponds to the TDD cycle in which the first signaling is received.

[0179] In an example, if the terminal 101 does not receive the first signaling within the TDD cycle, it may determine whether the subband exists within the TDD cycle based on a default rule.

[0180] Exemplarily, whether a subband exists in the TDD cycle may be determined based on whether a semi-static subband configuration exists in the TDD cycle.

[0181] Exemplarily, if there is a semi-static subband configuration, that is, the network device 102 configures the semi-static subband configuration, the terminal 101 may determine that the subband exists in the TDD period.

[0182] Furthermore, the terminal 101 may determine that the resources occupied by the subband in the TDD period are second resources, where the second resources are determined based on a semi-static subband configuration.

[0183] Exemplarily, if there is no semi-static subband configuration, that is, the network device 102 does not configure the semi-static subband configuration, the terminal 101 may determine that the subband does not exist in the TDD period.

[0184] Furthermore, the terminal 101 may determine resources within the TDD period according to the TDD configuration.

[0185] In some embodiments, the time window determined by terminal 101 includes a specific time window after terminal 101 receives the first signaling.

[0186] In one example, the terminal 101 determines the first time point of receiving the first signaling as the starting time point of the time window, and determines the number of time units included in the time window to be a first value.

[0187] In one example, the first value may be determined based on a predefined manner, such as based on a protocol agreement.

[0188] For example, the terminal 101 may determine that the time window starts from a first time point, and the number of time units occupied is a first value agreed upon by the protocol, such as N TDD cycles, or N time slots, or N radio frames.

[0189] In an example, the terminal 101 receives second signaling, where the second signaling is used to configure the first value.

[0190] For example, the terminal 101 can determine that the time window starts from the first time point, and the number of time units occupied is the first value configured by the network device 102 through the semi-static second signaling, such as N TDD cycles, or N time slots, or N wireless frames, etc.

[0191] In step S2104 , the network device 102 determines a time window.

[0192] In some embodiments, the sub-band resource indication information is valid within the time window.

[0193] In some embodiments, the time window is the valid time domain range of the sub-band resource indication information.

[0194] In some embodiments, the network device 102 may determine the time window based on a predefined method, including but not limited to a protocol agreement.

[0195] In some embodiments, the network device 102 may determine the first time point when the terminal 101 receives the first signaling as the starting time point of the time window, and determine the second time point as the ending time point of the time window.

[0196] In an example, the second time point is the time point when the terminal 101 successfully receives the next adjacent first signaling.

[0197] It is understandable that the network device 102 may determine the time window from when the terminal 101 successfully receives the first signaling to when the terminal 101 successfully receives the next adjacent first signaling.

[0198] In one example, before the second time when the terminal 101 successfully receives the next adjacent first signaling, the network device 102 can determine that the terminal 101 always determines the resources occupied by the subband according to the subband resource indication information carried in the first signaling.

[0199] Exemplarily, the network device 102 may determine, before the second time point, that the subband occupies the first resource indicated by the subband resource indication information.

[0200] In some embodiments, the network device 102 may determine that the time window corresponds to a time division duplexing (TDD) period.

[0201] In one example, a TDD period is a period of sending and / or receiving behavior. In an embodiment of the present disclosure, the network device 102 may determine that the time window corresponds to the TDD period for sending the first signaling.

[0202] In an example, if the network device 102 does not send the first signaling to the terminal 101 within the TDD cycle, the network device 102 may determine whether the subband exists within the TDD cycle based on a default rule.

[0203] Exemplarily, the network device 102 may determine whether a subband exists in the TDD period based on whether a semi-static subband configuration is configured for the terminal 101 in the TDD period.

[0204] For example, if the network device 102 is configured with a semi-static subband configuration, that is, the network device 102 is configured with a semi-static subband configuration, the network device 102 may determine that the subband exists within the TDD period.

[0205] Furthermore, the network device 102 may determine that the resources occupied by the subband in the TDD period are second resources, where the second resources are determined based on the semi-static subband configuration.

[0206] For example, if the network device 102 is not configured with a semi-static subband configuration, the network device 102 may determine that the subband does not exist in the TDD period.

[0207] Furthermore, the network device 102 determines that the terminal 101 determines the resources within the TDD period according to the TDD configuration.

[0208] In some embodiments, the network device 102 determines that the time window includes a specific time window after the terminal 101 receives the first signaling.

[0209] In one example, the network device 102 determines the first time point when the terminal 101 successfully receives the first signaling as the starting time point of the time window, and determines the number of time units included in the time window to be a first value.

[0210] In one example, the first value may be determined based on a predefined manner, such as based on a protocol agreement.

[0211] For example, the network device 102 may determine that the time window starts from a first time point and the number of time units occupied is a first value agreed upon by the protocol, such as N TDD cycles, or N time slots, or N radio frames.

[0212] In an example, the network device 102 may configure the first value, for example, by sending a second signaling to the terminal 101, where the second signaling is used to configure the first value.

[0213] For example, the network device 102 can determine that the time window starts from the first time point, and the number of time units occupied is the first value configured by the network device 102 through the semi-static second signaling, such as N TDD cycles, or N time slots, or N wireless frames, etc.

[0214] In some embodiments, before the sub-band resource indication information takes effect, the network device 102 may perform uplink and downlink scheduling based on the TDD time slot configuration sent by the network device 102 .

[0215] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0221] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if terminal 101 and network device 102 do not need to determine the number of time units included in the time window, step S2102 may not be performed. For another example, if terminal 101 and network device 102 determine the first value based on a predefined method, step S2102 may not be performed.

[0222] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the terminal 101 determines the time window based on a method other than the predefined method, step S2103 may not be performed.

[0223] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the network device 102 determines the time window based on a method other than the predefined method, step S2104 may not be performed.

[0224] In some embodiments, steps S2101 to S2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0225] In the above embodiment, the network device may send a first signaling message to the terminal, the first signaling message carrying subband resource indication information. Furthermore, the network device and the terminal may determine a time window, based on a predefined method, during which the subband resource indication information takes effect. This allows the terminal and the network device to have a consistent understanding of the effective time domain range of the subband resource indication information, thereby improving the reliability and availability of full-duplex communication.

[0319] FIG3D is an interactive diagram of a method for determining a time window according to an embodiment of the present disclosure. As shown in FIG3D , an embodiment of the present disclosure relates to a method for determining a time window, the method comprising:

[0320] Step S3401: Send a first signaling.

[0321] In some embodiments, the first signaling may carry sub-band resource indication information.

[0322] In some embodiments, the sub-band resource indication information is used to indicate the time domain resources and / or frequency domain resources occupied by the sub-band.

[0323] In some embodiments, the optional implementation of step S3401 can refer to the optional implementation of step S2201 in Figure 2B and other related parts of the embodiment involved in Figure 2B, which will not be repeated here.

[0324] Step S3402: Send time window indication information.

[0325] In some embodiments, the network device 102 may configure the time window and send the time window indication information to the terminal 101 .

[0326] In some embodiments, the optional implementation of step S3402 can refer to the optional implementation of step S2202 in Figure 2B and other related parts of the embodiment involved in Figure 2B, which will not be repeated here.

[0327] In some embodiments, the method for determining a time window according to embodiments of the present disclosure may include at least one of steps S3401 and S3402. For example, step S3401 may be implemented as an independent embodiment, step S3402 may be implemented as an independent embodiment, and steps S3401 and S3402 may be implemented as independent embodiments, but are not limited thereto.

[0328] In some embodiments, step S3401 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the network device 102 sends subband resource indication information via semi-static signaling, step S3401 may not be performed.

[0329] In some embodiments, step S3402 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the network device 102 determines the time window based on a predefined method, step S3402 may not be performed.

[0330] In some embodiments, steps S3401 to S3402 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0331] In the above embodiment, the network device can send a first signaling, which carries sub-band resource indication information. Furthermore, the network device sends a time window indication information so that the terminal can determine the time window, and the sub-band resource indication information is effective within the time window, thereby improving the reliability and availability of full-duplex communication.

[0332] The above process is further illustrated below with examples.

[0333] In an embodiment of the present disclosure, when a full-duplex terminal receives dynamic signaling sent by a full-duplex network device to indicate subband time-frequency resources, it determines the effective time domain range of the subband time-frequency resources indicated by the dynamic signaling through protocol pre-definition or indication signaling of the base station.

[0334] Terminal side:

[0335] After receiving the dynamic signaling sent by the full-duplex network device to indicate the subband time-frequency resource information, the full-duplex terminal determines the effective time domain range of the subband time-frequency resource information according to a method predefined by the protocol or explicit indication information of the base station.

[0336] Method 1: The effective time domain range of the subband time-frequency resource starts after the terminal receives the dynamic indication information and ends when the terminal receives the next valid dynamic indication information.

[0337] Before receiving dynamic signaling to update the time-frequency resources of the subband, the terminal always determines the time-frequency resources of the subband according to the successfully received dynamic subband time-frequency resource indication information.

[0338] Method 2: The effective time of the subband time-frequency resource is the TDD period (periodicity) in which the dynamic indication signaling is received, that is, the TDD UL-DL periodicity.

[0339] If the terminal does not detect and receive dynamic subband indication information in the TDD UL-DL periodicity, the terminal determines the subband configuration or TDD configuration according to the semi-static signaling.

[0340] If the base station configures a semi-static subband configuration for the terminal, the terminal determines the subband time-frequency domain resources according to the semi-static signaling.

[0341] If the base station does not configure the semi-static subband configuration for the terminal, the terminal considers that no subband exists within the TDD UL-DL periodicity.

[0342] Method 3: The effective time of the subband time-frequency domain resources is determined by the indication information in the dynamic signaling.

[0343] The dynamic signaling for indicating the subband time-frequency domain resources includes a time domain range in which the subband time-frequency resources are effective.

[0344] Method 4: The effective time of the subband time-frequency domain resource is a specific time window after the terminal receives the dynamic indication signaling.

[0345] The length of the time window is a value predefined by the protocol, such as N TDD UL-DL periodicities, or N slots, or N radio frames.

[0346] Alternatively, the length of the time window is a value configured by the base station through semi-static signaling, such as N TDD UL-DL periodicities, or N slots, or N radio frames.

[0347] Network device side:

[0348] After the duplex network device sends dynamic signaling for indicating subband time-frequency resource information to the full-duplex terminal, it indicates the effective time domain range of the subband time-frequency resource information to the terminal according to a method predefined by the protocol or explicit indication information of the base station.

[0349] Method 1: The effective time domain range of the subband time-frequency resource starts after the terminal receives the dynamic indication information and ends when the terminal receives the next valid dynamic indication information.

[0350] The specific method is as on the terminal side and will not be repeated here.

[0351] Method 2: The effective time of the subband time-frequency resource is the TDD UL-DL periodicity in which the dynamic indication signaling is received.

[0352] The specific method is as on the terminal side and will not be repeated here.

[0353] Method 3: The effective time of the subband time-frequency domain resources is determined by the indication information in the dynamic signaling.

[0354] The specific method is as on the terminal side and will not be repeated here.

[0355] Method 4: The effective time of the subband time-frequency domain resource is a specific time window after the terminal receives the dynamic indication signaling.

[0356] The specific method is as on the terminal side and will not be repeated here.

[0357] In Example 1, it is assumed that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, and this patent does not impose any restrictions. It is assumed that the base station side performs full-duplex operation on the semi-static DL symbol of the TDD frequency band or the DL symbol indicated by the SFI, that is, schedules downlink data and uplink data at the same time. It should be noted that the base station side can also perform full-duplex operation on the semi-static UL symbol of the TDD frequency band or the UL symbol indicated by the SFI, that is, schedules downlink data and uplink data at the same time. The semi-static flexible symbol is determined by the time division duplex uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) sent by the base station or by the tdd-UL-DL-ConfigurationCommon and the time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated).

[0358] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.

[0359] Taking into account the service load of network equipment, interference conditions, service type of terminals, etc., the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling. In this embodiment, there is no limitation on the dynamic signaling used to dynamically indicate subband time-frequency resources.

[0360] In this embodiment, the full-duplex network device and the full-duplex terminal determine the time domain range in which the subband time-frequency resource indicated by the dynamic signaling is effective by the following method:

[0361] The effective time domain range of the subband time-frequency resource starts after the terminal receives the dynamic indication information and ends when the terminal receives the next valid dynamic indication information.

[0362] Before receiving dynamic signaling to update the time-frequency resources of the subband, the terminal always determines the time-frequency resources of the subband according to the successfully received dynamic subband time-frequency resource indication information.

[0363] Example 2, assuming that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, this patent does not impose any restrictions. It is assumed that the base station side performs full-duplex operation on the semi-static DL symbol of the TDD frequency band or the DL symbol indicated by the SFI, that is, schedules downlink data and uplink data at the same time. It should be noted that the base station side can also perform full-duplex operation on the semi-static UL symbol of the TDD frequency band or the UL symbol indicated by the SFI, that is, schedules downlink data and uplink data at the same time. The semi-static flexible symbol is determined by the tdd-UL-DL-ConfigurationCommon sent by the base station or by the tdd-UL-DL-ConfigurationCommon and the tdd-UL-DL-ConfigurationDedicated.

[0364] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.

[0365] Taking into account the service load of network equipment, interference conditions, service type of terminals, etc., the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling. In this embodiment, there is no limitation on the dynamic signaling used to dynamically indicate subband time-frequency resources.

[0366] In this embodiment, the full-duplex network device and the full-duplex terminal determine the time domain range in which the subband time-frequency resource indicated by the dynamic signaling is effective by the following method:

[0367] The effective time of the subband time-frequency resource is the TDD UL-DL periodicity in which the dynamic indication signaling is received.

[0368] If the terminal does not detect and receive dynamic subband indication information in the TDD UL-DL periodicity, the terminal determines the subband configuration or TDD configuration according to the semi-static signaling.

[0369] If the network device configures a semi-static subband configuration for the terminal, the terminal determines the subband time-frequency domain resources according to the semi-static signaling.

[0370] If the network device does not configure the semi-static subband configuration for the terminal, the terminal considers that no subband exists within the TDD UL-DL periodicity.

[0371] Example 3, assuming that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, this patent does not impose any restrictions. Assume that the network device performs full-duplex operation on the semi-static DL symbol of the TDD frequency band or the DL symbol indicated by the SFI, that is, it schedules downlink data and uplink data at the same time. It should be noted that the network device can also perform full-duplex operation on the semi-static UL symbol of the TDD frequency band or the UL symbol indicated by the SFI, that is, it schedules downlink data and uplink data at the same time. The semi-static flexible symbol is determined by the tdd-UL-DL-ConfigurationCommon sent by the base station or by the tdd-UL-DL-ConfigurationCommon and the tdd-UL-DL-ConfigurationDedicated.

[0372] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.

[0373] Taking into account the service load of network equipment, interference conditions, service type of terminals, etc., the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling. In this embodiment, there is no limitation on the dynamic signaling used to dynamically indicate subband time-frequency resources.

[0374] In this embodiment, the full-duplex network device and the full-duplex terminal determine the time domain range in which the subband time-frequency resource indicated by the dynamic signaling is effective by the following method:

[0375] The effective time of the subband time-frequency domain resource is determined by the indication information in the dynamic signaling.

[0376] The dynamic signaling for indicating the subband time-frequency domain resources includes a time domain range in which the subband time-frequency resources are effective.

[0377] Example 4, assuming that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, this patent does not impose any restrictions. Assume that the network device performs full-duplex operation on the semi-static DL symbol of the TDD frequency band or the DL symbol indicated by the SFI, that is, it schedules downlink data and uplink data at the same time. It should be noted that the network device can also perform full-duplex operation on the semi-static UL symbol of the TDD frequency band or the UL symbol indicated by the SFI, that is, it schedules downlink data and uplink data at the same time. The semi-static flexible symbol is determined by the tdd-UL-DL-ConfigurationCommon sent by the base station or by the tdd-UL-DL-ConfigurationCommon and the tdd-UL-DL-ConfigurationDedicated.

[0378] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.

[0379] Taking into account the service load of network equipment, interference conditions, service type of terminals, etc., the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling. In this embodiment, there is no limitation on the dynamic signaling used to dynamically indicate subband time-frequency resources.

[0380] In this embodiment, the full-duplex network device and the full-duplex terminal determine the time domain range in which the subband time-frequency resource indicated by the dynamic signaling is effective by the following method:

[0381] The effective time of the subband time-frequency domain resource is a specific time window after the terminal receives the dynamic indication signaling.

[0382] The length of the time window is a value predefined by the protocol, such as N TDD UL-DL periodicities, or N slots, or N radio frames.

[0383] Alternatively, the length of the time window is a value configured by the base station through semi-static signaling, such as N TDD UL-DL periodicities, or N slots, or N radio frames.

[0384] Wherein, N is an integer greater than 1.
