[0214] FIG2A is an interactive diagram illustrating an information determination method according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to an information determination method, the method comprising:

[0215] In step S2100 , the network device 102 configures a first subband for the terminal 101 .

[0216] In some embodiments, terminal 101 determines the first sub-band.

[0217] In some embodiments, the time unit in the embodiments of the present disclosure may be a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or a span, which is not limited in the present disclosure. A span includes multiple consecutive symbols.

[0218] In some embodiments, the first time unit may be defined as a Subband-Based Full Duplex (SBFD) time unit, and the SBFD time unit is shown in FIG. 2B , for example.

[0219] In some embodiments, the transmission direction of the first time unit is flexible, and the network device configures a first subband in the first time unit with the flexible transmission direction. The first subband may be an uplink subband or a downlink subband.

[0220] Exemplarily, if the network device 102 configures an uplink subband for the terminal 101 in a first time unit with a flexible transmission direction, the terminal 101 may perform uplink transmission within the frequency domain range of the uplink subband of the first time unit.

[0221] Exemplarily, if the network device 102 configures a downlink subband for the terminal 101 in a first time unit with a flexible transmission direction, the terminal 101 may perform downlink transmission within the frequency domain range of the downlink subband of the first time unit.

[0222] In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band. For example, the network device 102 configures an uplink sub-band for the terminal 101 in a downlink (DL) time unit.

[0223] Accordingly, the terminal 101 may perform uplink transmission within the uplink subband range of the downlink time unit, or the terminal 101 may perform downlink transmission within other frequency domain ranges of the downlink time unit.

[0224] In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band. For example, the network device 102 configures a downlink sub-band for the terminal 101 in an uplink (UL) time unit.

[0225] Accordingly, the terminal 101 may perform downlink transmission within the downlink subband range of the uplink time unit, or the terminal 101 may perform uplink transmission within other frequency domain ranges of the downlink time unit.

[0226] In some embodiments, the network device 102 may indicate the time division duplexing uplink and downlink configuration (TDD UL DL configuration) currently used by the terminal in a semi-static or dynamic manner.

[0227] For example, the network device 102 may configure a semi-static TDD UL DL configuration via system messages, such as a System Information Block (SIB) and / or Radio Resource Control signaling (RRC signaling). The base station configures the cell-level time division multiplexing uplink and downlink configuration via higher layer signaling.

[0228] During the period configured by the base station, the base station configures the positions and quantities of downlink time units, flexible time units, and uplink time units.

[0229] Exemplarily, the network device 102 may dynamically indicate the uplink and downlink structures of one or more slots through a slot format indicator (SFI) carried by downlink control information (DCI) format 2_0.

[0230] Based on the current TDD UL-DL configuration, a certain amount of time is required to switch between DL and UL. This ensures that terminal 101 has sufficient lead time and switching time. This also ensures that network device 102 has sufficient time to perform the switch between receiving and transmitting. This switching time between UL and DL can be guaranteed by terminal 101 sending in advance.

[0231] However, whether using semi-static or dynamic configuration, the TDD UL / DL configuration applies to the entire operating bandwidth. This means that when both uplink and downlink resources exist within a timeslot, such as an SBFD slot, the number of switching points must be determined within a certain time domain range. A switching point is the time domain range within which a terminal switches transmission direction.

[0232] For example, as shown in FIG2C , terminal 101 can perform downlink-to-uplink switching based on the scheduling of network device 102. When network device 102 schedules terminal 101 to perform transmission in different transmission directions on adjacent SBFD slots, terminal 101 requires a certain switching time, as shown in FIG2D , resulting in some symbols being unusable for data transmission.

[0233] Both the terminal 101 and the network device 102 need to clearly define the number of switching points to avoid the network device 102 from performing unnecessary scheduling or configuration and to avoid wasting network signaling resources.

[0234] In step S2101 , the network device 102 determines the transmission configuration of the terminal 101 .

[0235] In some embodiments, the transmission configuration indicates the length of the time window.

[0236] In one example, the time window includes at least one of the first time units.

[0237] In an example, the time window includes a plurality of time units continuously occupied by the first subband in the time domain.

[0238] Exemplarily, the time window includes an existence range of the first subband in the time domain, which is determined as the time window.

[0239] For example, as shown in FIG2E , the first subband occupies slot#0 to slot2, and the time window includes slot#0 to slot2, wherein slot#0 to slot#2 are both first time units, namely, SBFD time units.

[0240] In one example, the time window includes multiple time units included in a time division multiplexing configuration period.

[0241] For example, the network device 102 configures the TDD UL-DL configuration, indicating a time division multiplexing configuration period, and the time window reuses the time division multiplexing configuration period. For example, as shown in FIG2F , the time window includes slot#0 to slot#4, where slot#1 to slot#3 are the first time unit.

[0242] In one example, the time window includes a first number of time units that are continuous in the time domain, and the first number of time units includes at least one of the first time units.

[0243] For example, as shown in FIG2G , the first number is 10, the starting time unit is slot#0, the time window includes slot#0 to slot#9, wherein slot#1 to slot#3, and slot#6 to slot#8 are the first time unit.

[0244] In some embodiments, the transmission configuration indicates the number of switching points.

[0245] In one example, since it takes a certain amount of time for the terminal 101 to switch the transmission direction, the switching point may be a time domain range in which the terminal switches the transmission direction.

[0246] In some embodiments, the transmission configuration indicates the length of the time window and the number of switching points.

[0247] Accordingly, the transmission configuration at this time indicates the number of switching points existing in the time window.

[0248] In some embodiments, the network device 102 may determine the above transmission configuration of the terminal based on predefined rules.

[0249] In one example, network device 102 can determine the length of the time window based on predefined rules.

[0250] Exemplarily, the protocol stipulates the length of the time window.

[0251] Exemplarily, the protocol stipulates a first number, and the network device 102 determines that the length of the time window is equal to the first number.

[0252] In one example, the network device 102 can determine the number of switching points based on predefined rules.

[0253] In one example, the network device 102 can determine the number of switching points within the time window based on predefined rules.

[0254] Exemplarily, the predefined rule may include, but is not limited to, determining the maximum number of switching points within the time window based on the terminal service type.

[0255] Among them, the terminal service type is the type of service being executed by the terminal 101, including but not limited to enhanced mobile broadband (Enhanced Mobile Broadband, eMBB) service, ultra-reliable low-latency communications (Ultra-Reliable Low-Latency Communications, URLLC) service, etc.

[0256] The network device 102 may obtain the service type indication information sent by the terminal 101 to determine the terminal service type, or may determine the terminal service type based on the service data sent by the terminal 101.

[0257] Exemplarily, the eMBB service may be agreed upon by a protocol, and the maximum number of switching points within the time window is M1.

[0258] For example, the URLLC service may be agreed upon by the protocol, and the maximum number of switching points within the time window is N1.

[0259] For example, other service types may be agreed upon by the protocol, and the maximum number of switching points within the time window is L.

[0260] Exemplarily, the predefined rule may include, but is not limited to, determining the maximum number of switching points within the time window based on a unit time length occupied by the transmission.

[0261] The unit time length is the length of the minimum time unit occupied by the transmission, including but not limited to one OFDM symbol, one slot, one sub-slot, etc.

[0262] For example, it may be agreed by the protocol that the unit time length occupied by the transmission is a slot, that is, the transmission is slot-based transmission, and the maximum number of switching points within the time window is M2.

[0263] For example, it may be agreed by the protocol that the unit time length occupied by the transmission is a sub-slot, that is, the transmission is based on the sub-slot, and the maximum number of switching points in the time window is N2.

[0264] Exemplarily, the predefined rule may include, but is not limited to, determining the maximum number of switching points within the time window based on channel priority.

[0265] Exemplarily, the channel may be designated as a high-priority channel by a protocol, and the maximum number of switching points within the time window is M3.

[0266] Exemplarily, the channel may be designated as a low-priority channel by a protocol, and the maximum number of switching points within the time window is N3.

[0267] The above-mentioned M1, M2, M3, N1, N2, N3, and L can be positive integers, and the present disclosure does not limit the specific numerical values.

[0268] Exemplarily, the predefined rule may include but is not limited to the absence of the switching point within one of the first time units.

[0269] The above description is merely exemplary, and all solutions in which the network device 102 determines the transmission configuration of the terminal 101 based on predefined rules should fall within the scope of protection of the present disclosure.

[0270] In some embodiments, the transmission configuration may be configured for the terminal 101 by the network device 102 .

[0271] The specific configuration method is similar to the solution of determining the transmission configuration of the terminal 101 based on the predefined rule, and will not be repeated here. In step S2102, the network device 102 sends an indication signaling to the terminal 101.

[0272] In some embodiments, terminal 101 receives the indication signaling.

[0273] In some embodiments, the name of the indication signaling is not limited, and it can be, for example, an indication message, a first message, a first signaling, etc.

[0274] In some embodiments, the indication signaling is used to indicate the transmission configuration configured by the network device 102 for the terminal 101 .

[0275] In some embodiments, the indication signaling is used to indicate the length of the time window.

[0276] In one example, the time window includes at least one of the first time units.

[0277] In an example, the time window includes a plurality of time units continuously occupied by the first subband in the time domain.

[0278] Exemplarily, the time window includes an existence range of the first subband in the time domain, which is determined as the time window.

[0279] In one example, the time window includes multiple time units included in a time division multiplexing configuration period.

[0280] Exemplarily, the network device 102 configures a TDD UL-DL configuration, and the terminal determines a time division multiplexing configuration period based on the TDD UL-DL configuration, where the time division multiplexing configuration period includes at least one first time unit.

[0281] In one example, the time window includes a first number of time units that are continuous in the time domain, and the first number of time units includes at least one of the first time units.

[0282] Accordingly, the indication signaling at this time can be used to configure the first number and the starting time unit of the time window.

[0283] In some embodiments, the indication signaling is used to indicate the number of switching points.

[0284] In one example, since it takes a certain amount of time for the terminal 101 to switch the transmission direction, the switching point may be a time domain range in which the terminal switches the transmission direction.

[0285] In some embodiments, the indication signaling is used to indicate the length of the time window and the number of switching points.

[0286] Correspondingly, the indication information at this time is used to indicate the number of switching points existing in the time window.

[0287] In some embodiments, the indication signaling is used to indicate the number of switching points. The network device 102 may configure the length of the time window for the terminal 101 through other signaling, which is not limited in this disclosure.

[0288] Exemplarily, the bit value indicated by the indication signaling is "011", and the terminal 101 determines that there are 3 switching points within the time window.

[0289] Exemplarily, the bit value indicated by the indication signaling is "000", and the terminal 101 determines that there are 0 switching points within the time window.

[0290] Exemplarily, if the number of switching points ranges from 0 to 5, when the bit value of the indication signaling is "110" or "111", the terminal 101 determines that there is no switching point within the time window, or there are 0 switching points.

[0291] For example, if the number of switching points ranges from 0 to 5, when the bit value of the indication signaling is "110" or "111", the indication signaling can be used to indicate other information, such as transmission direction, time window length, or other information related to the transmission configuration.

[0292] In some embodiments, the indication signaling is used to indicate whether a switching point exists within the time window.

[0293] Exemplarily, the indication signaling may indicate, through 1 bit, whether the switching point exists within the time window.

[0294] For example, if the bit value of the indication signaling is "1", the terminal 101 determines that there is a switching point within the time window. If the bit value of the indication signaling is "0", the terminal 101 determines that there is no switching point within the time window. Vice versa.

[0295] Exemplarily, the indication signaling may multiplex other signaling, and use an additional bit of the other signaling to indicate whether a switching point exists within the time window.

[0296] Exemplarily, the indication signaling may be dedicated signaling, which indicates through one bit whether a switching point exists within the time window.

[0297] Exemplarily, the indication signaling is used to indicate whether there is a switching point within the time window and the number of switching points.

[0298] For example, the indication signaling indicates that there is no switching point within the time window and indicates that the number of switching points is zero.

[0299] For another example, the indication signaling indicates that there are switching points within the time window, and indicates the number of switching points, where the number of switching points is a positive integer.

[0300] For another example, the indication signaling indicates that there is a switching point in the time window and indicates the number of switching points, and the number of switching points is 0. In this case, it should be understood that there is no switching point in the time window.

[0301] For another example, the indication signaling indicates that there is no switching point in the time window and indicates that the number of switching points is a positive integer. In this case, it should be understood that there is no switching point in the time window.

[0302] In step S2103, the terminal 101 determines the transmission configuration.

[0303] In some embodiments, the indication signaling sent by the network device 102 at least indicates the length of the time window, and the terminal 101 determines the time window based on the above indication signaling.

[0304] In some embodiments, the terminal 101 determines the time window based on predefined rules.

[0305] In some embodiments, the transmission configuration sent by the network device 102 does not indicate the length of the time window, and the terminal 101 determines the time window based on predefined rules.

[0306] In some embodiments, the transmission configuration sent by the network device 102 at least indicates the number of switching points, and the terminal 101 determines the number of switching points based on the above-mentioned indication signaling.

[0307] In some embodiments, terminal 101 determines the number of switching points based on predefined rules.

[0308] In some embodiments, the transmission configuration sent by the network device 102 does not indicate the number of switching points, and the terminal 101 determines the number of switching points based on a predefined rule.

[0309] In some embodiments, the transmission configuration indicates the number of switching points. The network device 102 may configure the length of the time window for the terminal 101 through other signaling, which is not limited in this disclosure.

[0310] Exemplarily, the bit value indicated by the indication signaling is "011", and the terminal 101 determines that there are 3 switching points within the time window.

[0311] Exemplarily, the bit value indicated by the indication signaling is "000", and the terminal 101 determines that there are 0 switching points within the time window.

[0312] Exemplarily, if the number of switching points ranges from 0 to 5, when the bit value of the indication signaling is "110" or "111", the terminal 101 determines that there is no switching point within the time window, or there are 0 switching points.

[0313] For example, if the number of switching points ranges from 0 to 5, when the bit value of the indication signaling is "110" or "111", the indication signaling can be used to indicate other information, such as transmission direction, time window length, or other information related to the transmission configuration.

[0314] In some embodiments, the indication signaling is used to indicate whether a switching point exists within the time window.

[0315] Exemplarily, the indication signaling may indicate, through 1 bit, whether the switching point exists within the time window.

[0316] For example, if the bit value of the indication signaling is "1", the terminal 101 determines that there is a switching point within the time window. If the bit value of the indication signaling is "0", the terminal 101 determines that there is no switching point within the time window. Vice versa.

[0317] Exemplarily, the indication signaling may multiplex other signaling, and use an additional bit of the other signaling to indicate whether a switching point exists within the time window.

[0318] Exemplarily, the indication signaling may be dedicated signaling, which indicates through one bit whether a switching point exists within the time window.

[0319] The manner in which the terminal 101 determines the transmission configuration based on the predefined rules is similar to the manner in which the network device 102 determines the transmission configuration, and will not be described in detail here.

[0320] Step S2104: The indication information is used to indicate that there is no switching point within the time window, and the network device 102 does not schedule the terminal to switch the transmission direction within the time window.

[0321] In some embodiments, the indication information is used to indicate that there is no switching point within the time window, and the network device 102 does not schedule the terminal to switch the transmission direction within the time window. The network device 102 can schedule or configure the terminal 101 to perform uplink transmission or downlink transmission. The specific transmission direction depends on the indication or configuration of the network device.

[0322] Alternatively, the indication signaling indicates that there are switching points within the time window and indicates the number of switching points. If the number of switching points is 0, the network device also does not schedule the terminal to switch the transmission direction within the time window.

[0323] Step S2105 : The indication information is used to indicate that there is no switching point within the time window, and the terminal 101 does not expect to switch the transmission direction within the time window.

[0324] In some embodiments, the indication signaling indicates that there is no switching point within the time window, and the terminal 101 does not expect to switch the transmission direction within the time window. That is, the terminal 101 only performs uplink transmission or downlink transmission within the time window, and the specific transmission direction depends on the instruction or configuration of the network device.

[0325] Alternatively, if the indication signaling indicates the presence of switching points within the time window and specifies the number of switching points, and the number of switching points is 0, the terminal also determines that there are no switching points within the time window. Terminal 101 does not expect to switch the transmission direction within the time window. That is, terminal 101 only performs uplink or downlink transmission within the time window, and the specific transmission direction depends on the indication or configuration of the network device.

[0326] In step S2106, terminal 101 determines that the number of times the transmission direction has been switched within the time window is equal to the number of switching points indicated by the transmission configuration, and does not expect to switch the transmission direction again within the time window. In some embodiments, the number of times the transmission direction has been switched within the time window is equal to the number of switching points indicated by the transmission configuration, and terminal 101 does not expect to switch the transmission direction again within the time window.

[0327] For example, the number of switching points indicated by the transmission configuration is 0, and the terminal 101 does not expect to switch the transmission direction within the time window.

[0328] For another example, the number of switching points indicated by the transmission configuration is 2, and the terminal 101 has switched the transmission direction twice, then the terminal 101 does not expect to switch the transmission direction again within the time window.

[0329] Step S2107 : The network device 102 determines that the number of times the transmission direction is switched within the time window is equal to the number of switching points indicated by the transmission configuration, and does not schedule the terminal 101 to switch the transmission direction again within the time window.

[0330] For example, the number of switching points indicated by the transmission configuration is 0, and the network device 102 does not schedule the terminal 101 to switch the transmission direction within the time window.

[0331] For another example, the number of switching points indicated by the transmission configuration is 2, the terminal 101 has switched the transmission direction twice, and the network device 102 no longer schedules the terminal 101 to switch the transmission direction again within the time window.

[0380] The above solution provided in the embodiment of the present disclosure is further illustrated below with examples.

[0381] Terminal side:

[0382] When the network device 102 configures the first subband for the full-duplex terminal 101, the terminal 101 determines the number of switching points within the time window according to the following method:

[0383] Method 1: The terminal 101 receives relevant configuration information of the network device 102 and determines the number P of uplink and downlink switching points existing in a certain time window.

[0384] The time window is a predefined value or a time window configured by the network device 102 and includes S consecutive slots.

[0385] Wherein, S can be an integer greater than or equal to 1.

[0386] The P switching points are located in one or more slots.

[0387] Method 2: The terminal 101 determines the number P of uplink and downlink switching points existing within a certain time window according to a predefined rule.

[0388] For eMBB services, or slot-based transmission, or channels indicated as low priority by the network device 102, the terminal 101 does not expect the number of uplink and downlink switching points within the time window to be greater than M.

[0389] For URLLC services, or sub-slot based transmissions, or channels indicated by the base station as high priority, the terminal does not expect the number of uplink and downlink switching points within the time window to be greater than N.

[0390] Exemplarily, the time window is a time domain range existing in the first sub-band time domain.

[0391] Method 3: Terminal 101 does not expect an uplink or downlink switching point to exist within an SBFD slot.

[0392] Method 4: The terminal 101 determines whether there is an uplink / downlink switching point between consecutive SBFD slots according to the indication information sent by the network device 102 .

[0393] When the indication information indicates that there is no uplink or downlink switching, the terminal can only perform uplink transmission or downlink transmission, depending on the indication or configuration of the base station.

[0394] Network device side:

[0395] When the network device 102 configures the first sub-band for the full-duplex terminal, the network device 102 determines the number of uplink and downlink switching points within the duration of the first sub-band according to the following method:

[0396] Method 1: The network device 102 configures relevant information for the terminal 101 to determine the number P of uplink and downlink switching points that exist in a certain time window.

[0397] The specific method is as described on the terminal 101 side and will not be repeated here.

[0398] Method 2: The network device 102 determines the number P of uplink and downlink switching points existing within a certain time window according to a predefined rule.

[0399] The specific method is as described on the terminal side and will not be repeated here.

[0400] Method 3: The network device 102 does not expect an uplink / downlink switching point to exist within an SBFD slot.

[0401] The specific method is as described on the terminal side and will not be repeated here.

[0402] Method 4: The network device 102 sends a signal to the terminal indicating whether there is an uplink or downlink switching point between consecutive SBFD slots.

[0403] The specific method is as described on the terminal side and will not be repeated here.

[0404] 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 network device performs full-duplex operation in the downlink time slot of the time division duplexing (TDD) frequency band, that is, it schedules downlink data and uplink data at the same time. When performing full-duplex operation, the network device adopts one of the following methods, and this patent does not impose any restrictions:

[0405] The frequency domain resources used for DL ​​transmission and UL transmission within a DL slot are independent of each other and do not overlap, as shown in FIG5A ;

[0406] The frequency domain resources used for DL ​​transmission and UL transmission in the DL slot completely overlap, as shown in FIG5B ;

[0407] Frequency domain resources used for DL ​​transmission and UL transmission in a DL slot partially overlap, as shown in FIG5C .

[0408] In this embodiment, the network device notifies the terminal of the number of uplink and downlink switching points within a certain time range through indication signaling. The switching points are used for switching between downlink to uplink (DL-to-UL) and / or uplink to downlink (UL-to-DL). This patent does not impose any restrictions on the time required for uplink and downlink switching.

[0409] In this embodiment, the frame structure is assumed to be DDDSU, where D stands for downlink, S stands for flexible, and U stands for uplink. The network device configures uplink subbands (UL subbands) for uplink data transmission in the second, third, and fourth slots for the terminal. Based on service requirements, the network device can schedule or configure the terminal to transmit uplink or receive downlink data in the SBFD slots. Once the transmission direction changes, a certain switching time is required between uplink and downlink, as shown in Figure 2C.

[0410] In this embodiment, the network device configures the number of uplink and downlink switching points within a certain time window for the full-duplex terminal through explicit signaling. The time window is determined as follows:

[0411] Time division multiplexing uplink and downlink configuration periodicity (TDD UL-DL configuration periodicity);

[0412] Or, UL subband time domain survival range;

[0413] Alternatively, the network device is configured with S consecutive slots, where S is an integer greater than or equal to 1.

[0414] The network device indicates to the terminal the number P of uplink and downlink switching points within the time window, where P is an integer greater than or equal to 1.

[0415] When the number of switching points within the time window is greater than P, the terminal will discard part of the uplink or downlink transmission. As a specific example, the terminal does not expect that there will still be a switch in transmission direction after P switching points.

[0416] In Example 2, 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 network device performs full-duplex operation in the downlink time slot of the time division duplexing (TDD) frequency band, that is, it schedules downlink data and uplink data at the same time. When performing full-duplex operation, the network device adopts one of the following methods, and this patent does not impose any restrictions:

[0417] The frequency domain resources used for DL ​​transmission and UL transmission within a DL slot are independent of each other and do not overlap, as shown in FIG5A ;

[0418] The frequency domain resources used for DL ​​transmission and UL transmission in the DL slot completely overlap, as shown in FIG5B ;

[0419] Frequency domain resources used for DL ​​transmission and UL transmission in a DL slot partially overlap, as shown in FIG5C .

[0420] In this embodiment, the network device notifies the terminal of the number of uplink and downlink switching points within a certain time range through indication signaling. The switching points are used for switching between downlink to uplink (DL-to-UL) and / or uplink to downlink (UL-to-DL). This patent does not impose any restrictions on the time required for uplink and downlink switching.

[0421] In this embodiment, the frame structure is assumed to be DDDSU, where D stands for downlink, S stands for flexible, and U stands for uplink. The network device configures uplink subbands (UL subbands) for uplink data transmission in the second, third, and fourth slots for the terminal. Based on service requirements, the network device can schedule or configure the terminal to transmit uplink or receive downlink data in the SBFD slots. Once the transmission direction changes, a certain switching time is required between uplink and downlink, as shown in Figure 2C.

[0422] In this embodiment, the terminal and the network device determine the number of uplink and downlink switching points within a certain time window according to predefined rules. The time window can be determined by the method described in Example 1, and this patent does not impose any restrictions.

[0423] The predefined rules include at least one of the following:

[0424] For eMBB services, slot-based transmission, or channels indicated as low priority by the network device, the terminal does not expect the number of uplink and downlink handovers within the time window to be greater than M;

[0425] For URLLC services, or sub-slot based transmissions, or channels indicated as high priority by the network device, the terminal does not expect the number of uplink and downlink switches within the time window to be greater than N.

[0426] When eMBB services and URLLC services exist at the same time, or slot-based transmission and sub-slot based transmission exist at the same time, or low priority channels and high priority channels exist at the same time, the terminal does not expect the number of uplink and downlink switches within the time window to be greater than N.

[0427] When the number of switching points within the time window is greater than M or N, the terminal will discard part of the uplink or downlink transmission. As a specific example, the terminal does not expect that there is still a switch in the transmission direction after M or N switching points.

[0428] In Example 3, similar to the scenario described in Example 1, in this example, the terminal does not expect an uplink / downlink switching point within an SBFD slot. That is, the terminal can only send uplink or downlink signals within an SBFD slot, and cannot send uplink signals on some symbols and receive downlink signals on the remaining symbols.

[0429] Correspondingly, the network device should avoid scheduling the terminal to perform transmission in different directions on different time domain resources within an SBFD slot.

[0430] In embodiment 4, as in the method of embodiment 3, the terminal network device sends an indication message to determine whether there is an uplink / downlink switching point in consecutive SBFD slots. The indication message is 1 bit, 0 indicates no switching point, and 1 indicates a switching point.

[0431] If the network device instructs the terminal that there is no switching point in the continuous SBFD slots, the terminal does not expect the transmission direction to change, that is, the terminal can only send or only receive in the continuous SBFD slots.

[0432] In the above embodiment, the number of switching points can be clearly defined within the time window, the number of switching points can be reasonably configured, the complexity of terminal control can be reduced, and the availability of full-duplex communication can be improved.

[0433] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
