[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0040] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The information determination method, apparatus, terminal, and network device provided in the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system can be a system using fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is merely an example and not a limitation.

[0044] Referring to FIG1 , FIG1 is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in FIG1 , the network system includes a user terminal 11 and a base station 12. The user terminal 11 may be a user equipment (UE), such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile internet device (MID), or a wearable device. It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present disclosure. The base station 12 may be a base station of 5G or later versions (e.g., gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present disclosure, only a 5G base station is used as an example, but the specific type of the base station 12 is not limited.

[0045] The embodiments of the present disclosure provide an information determination method, apparatus, terminal, and network device to determine the status of configured SBFD symbols.

[0046] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0047] As shown in FIG2 , an embodiment of the present disclosure provides an information determination method, which is executed by a terminal and includes:

[0048] Step S201: Determine whether the first sub-band full-duplex (SBFD) symbol is valid.

[0049] It should be noted that in order to solve the problem of mismatch between the TDD period and the synchronization signal block (Synchronization Signal and PBCH block, SS / PBCH block, SSB for short) period, it is allowed to configure SBFD symbols on the symbols where the SSB is located. The embodiment of the present disclosure determines whether the first SBFD symbol is effective, thereby clarifying the status of the configured SBFD symbol and ensuring communication reliability.

[0050] It should be noted that the first SBFD symbol mentioned in the embodiment of the present disclosure at least includes the SBFD symbol configured on the symbol where the synchronization signal block (SS / PBCH block, SSB) is located.

[0051] In some embodiments, in one implementation, determining that the first SBFD symbol is valid, the method further includes:

[0052] determining that an uplink subband on the first SBFD symbol is capable of uplink transmission; or

[0053] Determining that an uplink subband on the first SBFD symbol cannot perform uplink transmission;

[0054] The first SBFD symbol is an SBFD symbol configured on the symbol where the SSB is located.

[0055] In some embodiments, in one implementation, it is determined that the first SBFD symbol is invalid, where the first SBFD symbol includes at least one of the following:

[0056] A11. The first SBFD symbol is an SBFD symbol configured at the symbol where the SSB is located;

[0057] It should be noted that this situation can be understood as the SBFD symbol configured only in the symbol where the SSB is located is the first SBFD symbol.

[0058] It should be noted that the SSB symbol mentioned here is the symbol of the SSB sent by the network device (that is, the symbol of the SSB actually sent by the network device), or the SSB symbol is the symbol of the SSB sent determined according to the SSB pattern (which can be understood as the symbol of the possible SSB sent determined according to the SSB pattern).

[0059] That is to say, the SBFD symbol configured on the symbol where the SSB is located is not effective, as shown in Figure 3. If the non-SSB symbol adjacent to the symbol where the SSB is located is also configured as an SBFD symbol, as shown in Figure 3, a time unit of length T needs to be reserved between the SBFD symbol and the SSB symbol. The time unit can be a symbol or a sampling interval. By reserving T time units, the switching problem of SBFD symbols and non-SBFD symbols, and / or the conflict problem between uplink and downlink can be solved. The T time units can be reserved by the network device, that is, the network device does not schedule uplink transmission or send downlink within T time units; or the protocol stipulates that when the terminal determines that the uplink transmission is valid, it needs to meet the requirement that the transmission opportunity needs to be separated from the SSB symbol by T time units in the time domain. If the transmission opportunity is separated from the symbol where the SSB is located by T time units in the time domain, the uplink transmission is valid, otherwise the uplink transmission is invalid. The uplink transmission may be a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), etc.; or the protocol stipulates that when the uplink transmission opportunity overlaps with the T time units, the overlapping part needs to be discarded and rate matching is performed on the non-overlapping part, and the uplink transmission may be PUSCH.

[0060] Alternatively, time is reserved by further stipulating that the K non-SSB symbols before and / or after the SSB symbol are not valid. That is, if the non-SSB symbols before and / or after the SSB symbol are also configured as SBFD symbols, as shown in FIG4 , the K=1 symbols before and / or after the SSB symbol are not valid. In some embodiments, it can be stipulated that the K non-SSB symbols are not used for uplink and downlink transmission.

[0061] It should be noted that time slot (slot) n in Figures 3 and 4 is the first time slot in the half wireless frame containing SSB, wherein the filled boxes in Figures 3 and 4 represent the symbols where the SSB is located.

[0062] As shown in Figures 3 and 4, this situation may lead to frequent switching between SBFD and non-SBFD, greatly increasing the complexity of network devices and terminals. To solve the problem of frequent switching between SBFD and non-SBFD, A12 can be considered.

[0063] A12. The first SBFD symbol is an SBFD symbol configured in the time slot where the SSB is located;

[0064] It should be noted that this situation can be understood as the SBFD symbol configured in the time slot where the SSB is located is the first SBFD symbol, including the SBFD symbol configured in the symbol where the SSB is located and the SBFD symbol configured in the symbol where the SSB is not located.

[0065] In some embodiments, the time slot where the SSB is located mentioned here is the time slot where the network device sends the SSB (that is, the time slot where the network device actually sends the SSB), or the time slot where the SSB is located is the time slot for sending the SSB determined according to the SSB pattern (which can be understood as the time slot where the SSB may be sent determined according to the SSB pattern).

[0066] That is to say, in this case, the SBFD symbol configured in the time slot where the SSB is located is considered to be ineffective, where the time slot where the SSB is located can be a candidate time slot where the SSB is located determined according to any one of the SSB pattern schemes A-Scheme G (pattern Case A-Case G), or a time slot determined according to the candidate time slot and the ssb-PositionsInBurst parameter in the system information block 1 (SIB1) / serving cell configuration command (ServingCellConfigCommon).

[0067] For example, the SSB time slot is based on SSB pattern Case B, and the carrier frequency is FR1 and greater than 3 GHz. The SBFD configuration and SSB pattern are shown in Figure 5. At this time, regardless of the SSB pattern actually sent by the network device, if slots n to n+3 determined by SSB pattern Case B are all configured as SBFD symbols, the SBFD symbols configured on slots n to n+3 are invalid. For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, the SSB pattern is Case B, and the carrier frequency is in FR1 and greater than 3GHz, ssb-PositionsInBurst indicates {11001111}, and the SSB actually sent at this time is shown in Figure 6. The SSB time slots determined according to the ssb-PositionsInBurst parameter are slot n, slot n+2, and slot n+3 in Figure 6. If slot n, slot n+2, and slot n+3 are configured as SBFD symbols, the SBFD symbols configured on slot n, slot n+2, and slot n+3 are not effective at this time. Since it is determined that there is actually no SSB in slot n+1 according to ssb-PositionsInBurst, if slot n+1 is configured as an SBFD symbol, it is valid at this time. It should be noted that, in Figures 5 and 6, slot n is the first time slot in the half wireless frame containing SSB; wherein, the filled boxes in Figures 5 and 6 represent the symbols where the SSB is located.

[0068] A13. The first SBFD symbol is the other SBFD symbols except the second SBFD symbol in the half radio frame containing the SSB, and the second SBFD symbol is the non-SSB symbol configured as the SBFD symbol in the half radio frame containing the SSB;

[0069] It should be noted that this situation can be understood as all SBFD symbols except the second SBFD symbol in the half radio frame of the SSB are the first SBFD symbols.

[0070] In some embodiments, in one implementation, the second SBFD symbol includes at least one of the following:

[0071] A131. For a half radio frame containing an SSB symbol, the second SBFD symbol is part of or all non-SSB symbols before the first SSB symbol of the first SSB time slot and / or after the last SSB symbol of the last SSB time slot in the half radio frame.

[0072] In some embodiments, in one implementation, the second SBFD symbol is part or all of the non-SSB symbols before the first SSB symbol of the time slot where the first SSB is located and / or after the last SSB symbol of the time slot where the last SSB is located in the half radio frame, including at least one of the following:

[0073] A1311. If the time slot before the time slot where the first SSB is located in the half radio frame is an SBFD time slot, the second SBFD symbol is part of or all of the non-SSB symbols before the first SSB symbol of the time slot where the first SSB is located in the half radio frame;

[0074] A1312. If the symbol preceding the time slot where the first SSB in the half radio frame is located is an SBFD symbol, the second SBFD symbol is part of or all of the non-SSB symbols preceding the first SSB symbol in the time slot where the first SSB in the half radio frame is located;

[0075] A1313. If the time slot following the time slot where the last SSB in the half radio frame is located is an SBFD time slot, the second SBFD symbol is part of or all of the non-SSB symbols following the last SSB symbol of the time slot where the last SSB in the half radio frame is located;

[0076] A1314. If the next symbol after the time slot where the last SSB in the half wireless frame is located is an SBFD symbol, the second SBFD symbol is part or all of the non-SSB symbols after the last SSB symbol in the time slot where the last SSB in the half wireless frame is located.

[0077] A132. For a half radio frame including an SSB symbol, between the first SSB symbol and the last SSB symbol, if the number of consecutive non-SSB symbols configured as SBFD symbols is greater than and / or equal to a second threshold, the second SBFD symbols are all or part of the consecutive non-SSB symbols configured as SBFD symbols.

[0078] It should be noted that the greater than and / or equal to herein mainly include greater than (corresponding to the mathematical symbol >) and greater than or equal to (corresponding to the mathematical symbol ≥).

[0079] For example, if the number of consecutive non-SSB symbols configured as SBFD symbols is greater than or equal to M, all or part of the M symbols may be effective, for example, M=4 / 8 / 16, etc.

[0080] It should be noted that the second threshold value may be specified by a protocol or configured by a network device.

[0081] For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, wherein the pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and is less than or equal to 3 GHz, the ssb-PositionsInBurst parameter indicates {1111}, and the second SBFD symbol is determined according to the above-mentioned A131. For the half wireless frame containing the SSB, it is assumed that the previous symbol of the time slot where the first SSB is located is a non-SBFD symbol, and the next symbol of the time slot where the last SSB is located is an SBFD symbol, as shown in Figure 7. At this time, all non-SSB symbols after the last SSB symbol in the time slot where the last SSB is located (such as the symbols marked with the dotted box in Figure 7) are effective, wherein slot n in the figure is the first time slot in the half wireless frame containing the SSB; wherein the filled box in Figure 7 represents the symbol where the SSB is located.

[0082] For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, where the pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and is less than or equal to 3 GHz, the ssb-PositionsInBurst parameter indicates {1100}, and the second SBFD symbol is determined according to the above A131. For the half wireless frame containing the SSB, it is assumed that the previous symbol of the time slot where the first SSB is located is a non-SBFD symbol, and the next symbol of the time slot where the last SSB is located is an SBFD symbol, as shown in Figure 8. At this time, all non-SSB symbols after the last SSB symbol in the time slot where the last SSB is located (such as the symbols in the dotted box in Figure 8) are effective, where slot n in the figure is the first time slot in the half wireless frame containing the SSB; where the filled box in Figure 7 represents the symbol where the SSB is located.

[0083] For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, where the pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and is less than or equal to 3 GHz, the ssb-PositionsInBurst parameter indicates {0011}, and the second SBFD symbol is determined according to the above A131. For the half wireless frame containing SSB, the previous symbol of the time slot where the first SSB is located is the SBFD symbol, and the next symbol of the last SSB time slot is the SBFD symbol, as shown in Figure 9. At this time, all non-SSB symbols before the first SSB symbol in the time slot where the first SSB is located (such as the symbols in the dotted box in Figure 9) and all non-SSB symbols after the last SSB symbol in the time slot where the last SSB is located (such as the symbols in the dotted box in Figure 9) are effective, where slot n in the figure is the first time slot in the half wireless frame containing SSB; where the filled box in Figure 9 represents the symbol where the SSB is located.

[0084] For example, the time slot where the SSB is located is determined based on the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, where the pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and greater than 3GHz, the ssb-PositionsInBurst parameter indicates {11111111}, and the second SBFD symbol is determined based on the above A131 and A132. According to A131, for the half wireless frame containing SSB, the previous symbol of the time slot where the first SSB is located is an SBFD symbol, and the next symbol of the time slot where the last SSB is located is an SBFD symbol, as shown in Figure 10. At this time, all non-SSB symbols before the first SSB symbol in the time slot where the first SSB is located (such as the symbols in the dotted box in Figure 10) and all non-SSB symbols after the last SSB symbol in the last SSB time slot (such as the symbols in the dotted box in Figure 10) are effective; according to A132, for example, M=8, at this time, the number of consecutive non-SSB symbols configured as SBFD symbols between slot n+1 and slot n+2 is equal to 8 (such as the symbols in the solid box in Figure 10), so the SBFD symbols configured on these 8 non-SSB symbols are also effective, where slot n in the figure is the first time slot in the half wireless frame containing SSB; where the filled box in Figure 10 represents the symbol where the SSB is located.

[0085] For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter in SIB1 / ServingCellConfigCommon, the SSB pattern is Case B, and the carrier frequency is in FR1 and greater than 3GHz, the ssb-PositionsInBurst indication is {11001111}, and the SSB actually sent at this time is shown in Figure 11. The SSB time slots determined according to the ssb-PositionsInBurst parameter are slot n, slot n+2, and slot n+3 in Figure 11. If slot n, slot n+2, and slot n+3 are configured as SBFD symbols, the SBFD symbols configured on slot n, slot n+2, and slot n+3 are not effective. n+1 and the two symbols before it and the four symbols after it are all configured as SBFD symbols. The number of non-SSB symbols continuously configured as SBFD symbols is equal to 20, which is greater than M (for example, M=16). At this time, the SBFD configuration on these 20 non-SSB symbols is effective.

[0086] It should also be noted here that for the non-SSB symbols configured as SBFD symbols in the boxes in Figures 7-11, it is also possible to consider that some of the non-SSB symbols in the box are effective, and thus time can be reserved between the SSB symbol and the non-SSB symbol configured as the SBFD symbol, thereby solving the switching problem of SBFD symbols and non-SBFD symbols, and / or the conflict problem between uplink and downlink. For example, the protocol may stipulate or the network device may instruct to reserve Q symbols in front and / or behind the box, where Q is an integer.

[0087] A14. The first SBFD symbol is an SBFD symbol configured in the TDD time slot configuration period where the SSB is located;

[0088] In some embodiments, the TDD timeslot configuration period may be any of the following:

[0089] A141, the time slot configuration period indicated by pattern1;

[0090] A142, pattern2 indicates the time slot configuration period;

[0091] A143: The sum of the time slot configuration period indicated by pattern1 and the time slot configuration period indicated by pattern2.

[0092] That is, if the time slot configuration period indicated by pattern1 and / or pattern2 contains SSB symbols, the SBFD symbols configured in the time slot configuration period indicated by pattern1 and / or pattern2 are not effective, or all fall back to downlink symbols or flexible symbols; or, the time slot configuration period indicated by pattern1 and / or pattern2 contains SSB symbols, the SBFD symbols within the first period are not effective, or all fall back to downlink symbols or flexible symbols, where the first period is the sum of the time slot configuration period indicated by pattern1 and the time slot configuration period indicated by pattern2.

[0093] A15. The first SBFD symbol is an SBFD symbol configured in the SBFD configuration period of the SSB;

[0094] In some embodiments, the SBFD configuration period is a SBFD sub-band time domain configuration period, and the SBFD configuration period is configured by a network device.

[0095] When the network device is configured with only one TDD-UL-DL pattern, the SBFD configuration period is the period of the TDD-UL-DL pattern; when the base station is configured with two TDD-UL-DL patterns, the SBFD configuration period is the sum of the periods of the two TDD-UL-DL patterns.

[0096] In some embodiments, the SSB mentioned in the embodiments of the present disclosure includes a cell defining (CD) SSB and / or a non-cell defining (NCD) SSB.

[0097] It should be noted that, when it is determined that the first SBFD symbol is not effective, the contents of the first SBFD symbols corresponding to the cell-defined SSB and the non-cell-defined SSB can be the same or different. For example, in the case of non-cell-defined SSB, A11 is used; in the case of cell-defined SSB, A12 or A13 is used.

[0098] In some embodiments, the SSB symbol mentioned in the embodiments of the present disclosure is the 4 consecutive symbols where the SSB is located.

[0099] In some embodiments, the symbol where the SSB is located mentioned in the embodiments of the present disclosure includes the symbol where at least one of the following is located:

[0100] B11, secondary synchronisation signals (SSS);

[0101] B12, Primary synchronization signal (PSS);

[0102] B13. Physical broadcast channel (PBCH).

[0103] In some embodiments, in one implementation, the method further includes:

[0104] Determining the first SBFD symbol based on the subcarrier spacing of the SSB and the subcarrier spacing of the activated bandwidth part (Bandwidth Part, BWP);

[0105] The activating BWP is activating the uplink BWP and / or activating the downlink BWP.

[0106] It should be noted that the symbol where the SSB is located is determined based on the 4 consecutive symbols where the SSB is located. When the subcarrier spacing of the SSB is the same as the subcarrier spacing of the activated BWP, the first SBFD symbol and the SSB symbol are aligned in time domain. When the subcarrier spacing of the SSB is different from the subcarrier spacing of the activated BWP, the first SBFD symbol needs to be determined based on the subcarrier spacing of the SSB and the subcarrier spacing of the activated BWP. For example, the first SBFD symbol is a continuous 4*2SCS_BWP-SCS_SSB symbol, where SCS_BWP represents the subcarrier spacing of the activated BWP, and SCS_SSB represents the subcarrier spacing of the SSB.

[0107] It should be noted that, in some embodiments, under one implementation method, whether the first SBFD symbol is effective can be determined without considering whether the activated uplink BWP and / or activated downlink BWP includes the frequency domain position where the SSB is located. In this way, from the perspective of the network device, the effectiveness of the first SBFD symbol is unified, and the effectiveness of the first SBFD symbol determined by different terminals will not be different, that is, some terminals determine that it is effective on the first SBFD symbol, and other terminals determine that it is not effective on the first SBFD symbol.

[0108] In some embodiments, in another implementation, determining whether the first SBFD symbol is valid may also be applicable only to the case where the frequency domain location where the SSB is located is included in the activated BWP. That is, the specific implementation of determining whether the first sub-band full-duplex SBFD symbol is valid includes:

[0109] If the activated BWP contains the frequency domain location of the SSB, determine whether the first SBFD symbol is valid;

[0110] The activating BWP is activating the uplink BWP and / or activating the downlink BWP.

[0111] That is to say, determining whether the first SBFD symbol is effective is only applicable when the frequency domain position where the activated uplink BWP and / or the activated downlink BWP includes the SSB is located. For the frequency domain position where the activated uplink BWP and / or the activated downlink BWP does not include the SSB, the first SBFD symbol is effective. This will result in different determinations of whether the first SBFD symbol is effective or not by different terminals, that is, the first SBFD symbol is effective for some terminals, while it is not effective for other terminals.

[0112] It should be noted that the specific scheme for determining whether the first SBFD symbol is effective can be used to support or not support uplink transmission on SSB symbols configured as SBFD symbols. As described above, when the first SBFD symbol is effective, it can be supported or not supported to support uplink transmission on SSB symbols configured as SBFD symbols; when the first SBFD symbol is not effective, it can be supported or not supported to support uplink transmission on SSB symbols configured as SBFD symbols.

[0113] In some embodiments, in one implementation, determining whether the first sub-band full-duplex SBFD symbol is valid includes at least one of the following:

[0114] C11. Determine whether the first SBFD symbol is valid according to the protocol;

[0115] It should be noted that this situation refers to the situation where whether the first SBFD symbol is effective is stipulated by the protocol, and both the terminal and the network device can obtain the information according to the protocol.

[0116] That is, the network device and the terminal determine whether the first SBFD symbol is effective or not according to the protocol provisions. In some embodiments, the above provisions can be applied to CD-SSB and NCD-SSB, and the first SBFD symbol can be respectively specified to be effective or not for CD-SSB and NCD-SSB. For example, considering that the CD-SSBs of co-channel adjacent cells may be aligned in the time domain, specifying that the first SBFD symbol is not effective will not introduce serious cross-interference. However, for NCD-SSB, considering that the NCD-SSBs in adjacent cells may not be aligned in the time domain and / or frequency domain, if the first SBFD symbol is specified to be ineffective, serious cross-interference will be introduced. Therefore, for CD-SSB, the first SBFD symbol is specified to be ineffective; for NCD-SSB, the first SBFD symbol is specified to be effective. For example, the time and frequency domain locations of the CD-SSB are known to UEs within the serving cell, but the location of the NCD-SSB may not be known to some UEs. If the SBFD configuration configured on the NCD-SSB symbol is not effective, the base station also needs to notify the UE of the location of the NCD-SSB. To avoid the resulting signaling overhead, it is possible to consider notifying the UE of the first SBFD symbol for the CD-SSB and not taking effect for the NCD-SSB. For example, considering that the CD-SSB carries the configuration information of CORESET#0 associated with SIB1, the terminal obtains system information based on the CORESET#0 associated with SIB1 and then accesses the cell, while the NCD-SSB cannot implement the aforementioned CD-SSB function. Furthermore, considering the randomness of initial cell access via CD-SSB and the base station's inability to predict this behavior and thus take measures to protect such behavior from interference from uplink transmissions, the first SBFD symbol is not effective for the CD-SSB and is effective for the NCD-SSB.

[0117] For example, the protocol stipulates that the SBFD symbol configured on the symbol where the SSB is located is effective. Furthermore, it stipulates that the uplink subband on the SBFD symbol can be transmitted uplink, or stipulates that the uplink subband on the SBFD symbol cannot be transmitted uplink.

[0118] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is ineffective, which means that the SBFD symbol configured on the symbol where the SSB is located is effective.

[0119] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is ineffective, and does not stipulate that the uplink subband on the symbol where the SSB is located cannot be transmitted uplink. This means that the SBFD symbol configured on the symbol where the SSB is located is effective and can be transmitted uplink.

[0120] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is not effective, and does not stipulate that the uplink subband on the symbol where the SSB is located cannot be transmitted uplink, which means that the SBFD symbol configured on the symbol where the SSB is located is effective, but cannot be transmitted uplink.

[0121] For example, the protocol stipulates that the SBFD symbol configured on the symbol where the SSB is located is not effective, and the protocol also stipulates whether A11, A12, or A13 is used.

[0122] C12. Determine whether the first SBFD symbol is valid according to the indication signaling sent by the network device, wherein the indication signaling is used to indicate whether the first SBFD symbol is valid;

[0123] It should be noted that this situation means that whether the first SBFD symbol is valid is determined by the network device and indicated to the terminal through indication signaling.

[0124] That is to say, the network device instructs the terminal through signaling whether the first SBFD symbol in the SBFD configuration is effective. For example, the signaling indicates two states, namely, effective and ineffective. In some embodiments, the signaling can be applicable to CD-SSB and NCD-SSB, that is, CD-SSB and NCD-SSB share a set of signaling. It can also be indicated separately for CD-SSB and NCD-SSB. The network device instructs the terminal through the first signaling whether the SBFD symbol configured on the CD-SSB symbol is effective or not, and instructs the terminal through the second signaling whether the SBFD symbol configured on the NCD-SSB symbol is effective or not. In some embodiments, the signaling can also indicate whether the SBFD symbol configured on the SSB corresponding to the SSB index is effective according to the SSB index.

[0125] It should be noted that the indication signaling may be carried in a cell common message (eg, in a SIB), or may be sent via terminal-specific RRC signaling.

[0126] C13. Determine whether the first SBFD symbol is valid according to the number of switches between the SBFD symbol and the non-SBFD symbol;

[0127] It should be noted that in this case, whether the first SBFD symbol is effective is determined based on the number of switches between the SBFD symbol and the non-SBFD symbol, and the terminal and the network device use the same rules to ensure consistent understanding between the terminal and the network device.

[0128] It should be noted that the switching between SBFD symbols and non-SBFD symbols includes: switching from SBFD symbols to non-SBFD symbols, and / or switching from non-SBFD symbols to SBFD symbols.

[0129] In some embodiments, in one implementation, the specific implementation of determining whether the first SBFD symbol is valid based on the number of switching between the SBFD symbol and the non-SBFD symbol includes at least one of the following:

[0130] C131. If a first switching number between the SBFD symbol and the non-SBFD symbol is greater than and / or equal to a first threshold, determine that the first SBFD symbol is valid;

[0131] It should be noted that the first threshold value may be specified by a protocol or configured by a network device.

[0132] In this case, it can be considered that as long as the number of switching between the SBFD symbol and the non-SBFD symbol within the time unit is greater than and / or equal to the first threshold, the first SBFD symbol is considered to be valid.

[0133] In some embodiments, the time unit may be an SBFD configuration period, or the time unit may be a period related to SBFD configuration.

[0134] It should be noted that the greater than and / or equal to herein mainly include greater than (corresponding to the mathematical symbol >) and greater than or equal to (corresponding to the mathematical symbol ≥).

[0135] C132. If the first switching number between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold, determine that the first SBFD symbol is invalid;

[0136] In this case, it can be considered that if the number of switchings between the SBFD symbol and the non-SBFD symbol within the time unit is less than and / or equal to the first threshold, the first SBFD symbol is considered to be valid.

[0137] In some embodiments, the time unit may be an SBFD configuration period, or the time unit may be a period related to SBFD configuration.

[0138] It should be noted that the less than and / or equal to herein mainly include less than (corresponding to the mathematical symbol <) and less than or equal to (corresponding to the mathematical symbol ≤).

[0139] It should be noted here that if the first switching number in C131 is greater than the first threshold value, then the first switching number in C132 is less than or equal to the first threshold value; if the first switching number in C131 is greater than or equal to the first threshold value, then the first switching number in C132 is less than the first threshold value.

[0140] C133. If the first switching number between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold, determine a second switching number between the SBFD symbol and the non-SBFD symbol when determining that the first SBFD symbol is not valid; if the second switching number is greater than and / or equal to the first threshold, determine that the first SBFD symbol is valid; if the second switching number is less than and / or equal to the first threshold, determine that the first SBFD symbol is not valid;

[0141] In this case, it can be considered that if the number of switches between the SBFD symbol and the non-SBFD symbol within the time unit is less than and / or equal to the first threshold value, the first SBFD symbol is temporarily determined to be invalid. Then, based on the assumption that the first SBFD symbol is invalid, the number of switches between the SBFD symbol and the non-SBFD symbol within the time unit is re-determined. As long as the re-determined number of switches is greater than and / or equal to the first threshold value, the first SBFD symbol is ultimately considered to be valid. Otherwise, the first SBFD symbol is considered to be invalid.

[0142] In some embodiments, the time unit may be an SBFD configuration period, or the time unit may be a period related to SBFD configuration.

[0143] It should be noted that this solution can prevent the number of switches between SBFD symbols and non-SBFD symbols within a time unit (eg, SBFD configuration period) from being greater than the first threshold due to the failure of the first symbol to take effect.

[0144] For example, if the number of SBFD symbol to non-SBFD symbol transitions and the number of non-SBFD symbol to SBFD symbol transitions within the SBFD configuration period is greater than or equal to N, the first SBFD symbol is effective. Otherwise, the number of transitions within the SBFD configuration period, determined after applying A11, A12, or A13, in which the first SBFD symbol is ineffective, is greater than N. If it is greater than N, the first SBFD symbol is effective. If it is less than or equal to N, A11, A12, or A13, in which the first SBFD symbol is ineffective, is applied. A13 can be based on A131, A132, or a combination of A131 and A132. N is a predefined value or a value configured by the network device, and is an integer, for example, N=2. In some embodiments, the network device and the terminal determine whether to determine the second SBFD symbol according to A131, or according to A131 and A132 based on the number of switches N. Specifically, when the number of switches within the SBFD configuration period determined after applying A131 is greater than N, the second SBFD symbol is not determined according to A131, nor according to A131 and A132; when the number of switches within the SBFD configuration period determined after applying A131 is less than or equal to N, and when the number of switches within the SBFD configuration period determined after applying A131 and A132 is greater than N, the second SBFD symbol may be determined according to A131; when the number of switches within the SBFD configuration period determined after applying A131 and A132 is less than or equal to N, the second SBFD symbol may be determined according to A131 and A132. For example, if N=2, the number of SBFD symbol to non-SBFD symbol conversions and the number of non-SBFD symbol to SBFD symbol conversions within the SBFD configuration period are equal to 0. At this time, the base station and the UE determine that the first SBFD symbol is not effective. The SBFD symbol determined according to A131 will introduce one switching from the SBFD symbol to the non-SBFD symbol and one switching from the non-SBFD symbol to the SBFD symbol. Therefore, in this case, the network device and the terminal can only determine the second SBFD symbol according to A131.For example, N=4, and the number of SBFD symbol to non-SBFD symbol conversions and the number of non-SBFD symbol to SBFD symbol conversions within the SBFD configuration period are equal to 0. In this case, the network device and the terminal determine that the first SBFD symbol is ineffective. The SBFD symbol determined according to A131 introduces one SBFD symbol to non-SBFD symbol switching and one non-SBFD symbol to SBFD symbol switching. In this case, if the number of switchings within the SBFD configuration period determined after applying A131 and A132 is less than or equal to 4, the network device and the terminal may determine the second SBFD symbol based on A131 and A132. If the number of switchings within the SBFD configuration period determined after applying A131 and A132 is greater than 4, and the terminal ultimately determines, according to A132, that there are multiple consecutive non-SSB symbols configured with SBFD symbols, two switchings may be introduced according to A132. Based on the forward-to-back time position rule and the N value, one or more consecutive non-SSB symbols configured with SBFD symbols are determined as the second SBFD symbol.
