Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0204] Next, the embodiments of the present application will be introduced in conjunction with the accompanying drawings. The information determination method, device, terminal, and network device provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system that adopts the fifth-generation (5G) mobile communication technology (hereinafter simply referred to as the 5G system). Those skilled in the art can understand that the 5G NR system is only an example and not a limitation.

[0205] See Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied. As Figure 1As shown in the figure, it includes a user terminal 11 and a base station 12. Among them, the user terminal 11 can be a user equipment (UE). For example, it can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device, etc. terminal-side devices. It should be noted that in the embodiments of this application, the specific type of the user terminal 11 is not limited. The above base station 12 can be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or called Node B. It should be noted that in the embodiments of this application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0206] Embodiments of this application provide an information determination method, device, terminal, and network device to implement the determination of the status of configured SBFD symbols.

[0207] Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be elaborated.

[0208] As Figure 2 shown, embodiments of this application provide an information determination method, which is executed by a terminal and includes:

[0209] Step S201: Determine whether the first sub-band full-duplex (SBFD) symbol is effective.

[0210] It should be noted that to solve the problem of the mismatch between the TDD period and the synchronization signal block (SS / PBCH block, SSB) period, it is allowed to configure SBFD symbols on the symbols where the SSB is located. In the embodiments of this application, by determining whether the first SBFD symbol is effective, the status of the configured SBFD symbol is clarified to ensure communication reliability.

[0211] It should be noted that the first SBFD symbol mentioned in the embodiments of this application at least includes the SBFD symbol configured on the symbol where the synchronization signal block (SS / PBCH block, SSB) is located.

[0212] Optionally, in one implementation manner, when it is determined that the first SBFD symbol is effective, the method further includes:

[0213] Determine that the uplink subbands on the first SBFD symbol can perform uplink transmission; or

[0214] Determine that the uplink subbands on the first SBFD symbol cannot perform uplink transmission;

[0215] Wherein, the first SBFD symbol is the SBFD symbol configured on the symbol where the SSB is located.

[0216] Optionally, in one implementation, determine that the first SBFD symbol is ineffective, and the first SBFD symbol includes at least one of the following:

[0217] A11. The first SBFD symbol is the SBFD symbol configured on the symbol where the SSB is located;

[0218] It should be noted that this situation can be understood as that only the SBFD symbol configured on the symbol where the SSB is located is the first SBFD symbol.

[0219] It should be noted that the symbol where the SSB is located mentioned here is the symbol on which the network device sends the SSB (i.e., the symbol on which the network device actually sends the SSB), or the symbol where the SSB is located is the symbol for sending the SSB determined according to the SSB pattern (which can be understood as the symbol that may send the SSB determined according to the SSB pattern).

[0220] That is to say, the SBFD symbol configured on the symbol where the SSB is located is ineffective, for example Figure 3 as shown. If the non-SSB symbol adjacent to the symbol where the SSB is located is also configured as an SBFD symbol, such as Figure 3As shown, at this time, a length of T time units 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 handover problem between the SBFD symbol and the non-SBFD symbol, and / or the conflict problem between the uplink and the downlink can be solved. The T time units can be reserved by a network device, that is, the network device does not schedule uplink transmission and does not send downlink within T time units; or it is stipulated by the protocol that when the terminal determines that the uplink transmission is valid, it is required 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 can be a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), etc.; or it is stipulated by the protocol 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. The uplink transmission can be PUSCH.

[0221] Alternatively, further reserve time by stipulating that K non-SSB symbols before and / or after the symbol where the SSB is located are ineffective, that is, if non-SSB symbols before and / or after the symbol where the SSB is located are also configured as SBFD symbols, as Figure 4 shown, the K = 1 symbol before and / or after the symbol where the SSB is located is ineffective. Optionally, it can be stipulated that the K non-SSB symbols are not used for uplink and downlink transmission.

[0222] It should be noted that Figure 3 and Figure 4 in, slot n is the first time slot in the half radio frame containing the SSB, where Figure 3 and Figure 4 the filled boxes in represent the symbols where the SSB is located.

[0223] As shown by Figure 3 and Figure 4 this may lead to frequent handovers between SBFD and non-SBFD, greatly increasing the complexity of the network device and the terminal. To solve the problem of frequent handovers between the network device and the terminal between SBFD and non-SBFD, A12 can be considered.

[0224] A12. The first SBFD symbol is the SBFD symbol configured in the time slot where the SSB is located;

[0225] It should be noted that in this case, the SBFD symbols configured in the time slot where the SSB is located can be understood as the first SBFD symbols, including the SBFD symbols configured in the symbol where the SSB is located and the SBFD symbols configured in the symbols other than the symbol where the SSB is located.

[0226] Optionally, the time slot where the SSB is located mentioned here is the time slot when the network device sends the SSB (i.e., the actual time slot when the network device 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 possible time slot for sending the SSB determined according to the SSB pattern).

[0227] That is to say, in this case, it is considered that the SBFD symbols configured in the time slot where the SSB is located are ineffective. Among them, the time slot where the SSB is located can be the candidate time slot where the SSB is located determined according to any one of the SSB pattern schemes A - G (pattern Case A - Case G), or the 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).

[0228] For example, the time slot where the SSB is located is determined according to SSB pattern Case B, and the carrier frequency is in FR1 and greater than 3 GHz. The SBFD configuration and SSB pattern are as Figure 5 shown. At this time, regardless of what the actual SSB pattern sent by the network device is, if the slots n to n + 3 determined according to SSB pattern Case B are all configured as SBFD symbols, the SBFD symbols configured on the slots n to n + 3 are ineffective at this time. 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 CaseB, and the carrier frequency is in FR1 and greater than 3 GHz. ssb - PositionsInBurst indicates {11001111}. At this time, the actual SSB sent is as Figure 6 shown. The SSB time slot determined according to the ssb - PositionsInBurst parameter is Figure 6In slot n, slot n+2, slot n+3, if slot n, slot n+2, slot n+3 are configured as SBFD symbols, the SBFD symbols configured on slot n, slot n+2, slot n+3 are not effective at this time. Since it is determined according to ssb-PositionsInBurst that slot n+1 actually has no SSB, if slot n+1 is configured as an SBFD symbol, it is effective at this time. It should be noted that Figure 5 and Figure 6 in, slot n is the first time slot in the half radio frame containing the SSB; among them, Figure 5 and Figure 6 the filled boxes in indicate the symbols where the SSB is located.

[0229] A13. The first SBFD symbol is other SBFD symbols in the half radio frame containing the SSB except the second SBFD symbol, and the second SBFD symbol is the symbol where the non-SSB configured as an SBFD symbol is located in the half radio frame containing the SSB;

[0230] It should be noted that this situation can be understood as that other SBFD symbols except the second SBFD symbol in the half radio frame except the SSB are all first SBFD symbols.

[0231] Optionally, in one implementation manner, the second SBFD symbol includes at least one of the following:

[0232] A131. For the half radio frame containing the symbol where the SSB is located, the second SBFD symbol is part or all of the non-SSB symbols before the first SSB symbol in the first time slot where the SSB is located and / or after the last SSB symbol in the last time slot where the SSB is located in the half radio frame;

[0233] Optionally, in one implementation manner, the second SBFD symbol is part or all of the non-SSB symbols before the first SSB symbol in the first time slot where the SSB is located and / or after the last SSB symbol in the last time slot where the SSB is located in the half radio frame, and includes at least one of the following:

[0234] A1311. If the time slot before the first time slot where the SSB is located in the half radio frame is an SBFD time slot, the second SBFD symbol is part or all of the non-SSB symbols before the first SSB symbol in the first time slot where the SSB is located in the half radio frame;

[0235] A1312. If the symbol before the time slot where the first SSB is located in the half radio frame is an SBFD symbol, the second SBFD symbol is part or all of the non-SSB symbols before the first SSB symbol in the time slot where the first SSB is located in the half radio frame;

[0236] A1313. If the time slot after the time slot where the last SSB is located in the half radio frame is an SBFD time slot, 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 is located in the half radio frame;

[0237] A1314. If the symbol after the time slot where the last SSB is located in the half radio frame 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 is located in the half radio frame.

[0238] A132. In the half radio frame containing the SSB symbols, 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 symbol is all or part of the SBFD symbols among the consecutive non-SSB symbols configured as SBFD symbols;

[0239] It should be noted that the greater than and / or equal to here mainly includes greater than (corresponding to the mathematical symbol >) and greater than or equal to (corresponding to the mathematical symbol ≥).

[0240] For example, if the number of consecutive non-SSB symbols configured as SBFD symbols is greater than or greater than or equal to M, all or part of the M symbols can take effect at this time. For example, M = 4 / 8 / 16, etc.

[0241] It should be noted that this second threshold can be specified by the protocol or configured by the network device.

[0242] 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 pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and less than or equal to 3 GHz. The ssb-PositionsInBurst parameter indicates {1111}. The second SBFD symbol is determined according to A131 above. In the half radio frame containing the SSB, assuming that the symbol before the time slot where the first SSB is located is not an SBFD symbol, and the symbol after the time slot where the last SSB is located is an SBFD symbol, as Figure 7As shown, all non-SSB symbols after the symbol where the last SSB in the last time slot of the current time is located (such as the symbols marked by the dashed box in the figure) become effective. Here, slot n in the figure is the first time slot in the half radio frame containing the SSB; among them, Figure 7 The filled box in represents the symbol where the SSB is located.

[0243] 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 pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and less than or equal to 3 GHz. The ssb-PositionsInBurst parameter indicates {1100}. The second SBFD symbol is determined according to the above A131. For the half radio frame containing the SSB, assume that the symbol before the first time slot where the first SSB is located is a non-SBFD symbol, and the symbol after the last time slot where the last SSB is located is a SBFD symbol. As Figure 8 shown, all non-SSB symbols after the symbol where the last SSB in the last time slot of the current time is located (such as Figure 8 the symbols within the dashed box) become effective. Here, slot n in the figure is the first time slot in the half radio frame containing the SSB; among them, Figure 7 The filled box in represents the symbol where the SSB is located.

[0244] 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 pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and less than or equal to 3 GHz. The ssb-PositionsInBurst parameter indicates {0011}. The second SBFD symbol is determined according to the above A131. For the half radio frame containing the SSB, the symbol before the first time slot where the first SSB is located is a SBFD symbol, and the symbol after the last time slot where the last SSB is located is a SBFD symbol. As Figure 9 shown, all non-SSB symbols before the first SSB symbol in the first time slot where the first SSB is located (such as Figure 9 the symbols within the dotted line box), and all non-SSB symbols after the symbol where the last SSB in the last time slot of the current time is located (such as Figure 9 the symbols within the dashed box) become effective. Here, slot n in the figure is the first time slot in the half radio frame containing the SSB; among them, Figure 9 The filled box in represents the symbol where the SSB is located.

[0245] 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 pattern corresponding to the candidate time slot is Case B, and the carrier frequency is in FR1 and greater than 3 GHz. The ssb-PositionsInBurst parameter indicates {11111111}. The second SBFD symbol is determined according to the above A131 and A132. According to A131, for the half radio frame containing the SSB, the symbol before the time slot where the first SSB is located is the SBFD symbol, and the symbol after the time slot where the last SSB is located is the SBFD symbol. As Figure 10 shown, all non-SSB symbols before the first SSB symbol in the time slot where the first SSB is located (such as Figure 10 the symbols within the dotted line box), and all non-SSB symbols after the last SSB symbol in the last SSB time slot (such as Figure 10 the symbols within the dashed line box) 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 Figure 10 the symbols within the solid line box). Therefore, the SBFD symbols configured on these 8 non-SSB symbols are also effective. Among them, slot n in the figure is the first time slot in the half radio frame containing the SSB; among them, Figure 10 the filled box represents the symbol where the SSB is located.

[0246] For example, the time slot where the SSB is located is determined according to the candidate time slot and the ssb-PositionsInBurst parameter. The SSB pattern is Case B, and the carrier frequency is in FR1 and greater than 3 GHz. ssb-PositionsInBurst indicates {11001111}. The actually transmitted SSB is as Figure 11 shown. The SSB time slots determined according to the ssb-PositionsInBurst parameter are Figure 11 slot n, slot n+2, slot n+3 in. If slot n, slot n+2, slot n+3 are configured as SBFD symbols, the SBFD symbols configured on slot n, slot n+2, slot n+3 are not effective at this time. Since slot n+1 and the 2 symbols before it and the 4 symbols after it are all configured as SBFD symbols, the number of consecutive non-SSB symbols 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.

[0247] It should also be noted here that for Figures 7 - 11 the symbols within the square box that are non-SSB and configured as SBFD symbols, it is also possible to consider that some of the non-SSB symbols within the square box become effective. Furthermore, time can be reserved between the SSB symbol and the non-SSB symbol configured as an SBFD symbol, thereby solving the switching problem between SBFD symbols and non-SBFD symbols, and / or the conflict problem between uplink and downlink. For example, it can be stipulated by the protocol or indicated by the network device that Q symbols are reserved before and / or after in the square box, where Q is an integer.

[0248] A14. The first SBFD symbol is an SBFD symbol configured within the TDD time slot configuration period where the SSB is located;

[0249] Optionally, the TDD time slot configuration period can be any of the following:

[0250] A141. The time slot configuration period indicated by pattern1;

[0251] A142. The time slot configuration period indicated by pattern2;

[0252] A143. The sum of the time slot configuration period indicated by pattern1 and the time slot configuration period indicated by pattern2.

[0253] That is, if the SSB symbol is included within the time slot configuration period indicated by pattern1 and / or pattern2, the SBFD symbols configured within the time slot configuration period indicated by pattern1 and / or pattern2 do not become effective, or all are reverted to downlink symbols or flexible symbols; or, if the SSB symbol is included within the time slot configuration period indicated by pattern1 and / or pattern2, the SBFD symbols within the first period range do not become effective, or all are reverted 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.

[0254] A15. The first SBFD symbol is an SBFD symbol configured within the SBFD configuration period where the SSB is located;

[0255] Optionally, the SBFD configuration period is the SBFD sub-band time domain configuration period, and the SBFD configuration period is configured by the network device.

[0256] When the network device is only configured with 1 TDD-UL-DL pattern, the SBFD configuration period is the period of the TDD-UL-DL pattern. When the base station is configured with 2 TDD-UL-DL patterns, the SBFD configuration period is the sum of the periods of the two TDD-UL-DL patterns.

[0257] Optionally, the SSB mentioned in the embodiments of the present application includes a Cell Defining (CD) SSB and / or a Non Cell Defining (NCD) SSB.

[0258] It should be noted here that in the case where the first SBFD symbol is determined to be ineffective, the content of the first SBFD symbol corresponding to the cell defining SSB and the non-cell defining SSB may be the same or different. For example, in the case of a non-cell defining SSB, A11 is used; in the case of a cell defining SSB, A12 or A13 is used.

[0259] Optionally, the symbol where the SSB is located in the embodiments of the present application is 4 consecutive symbols where the SSB is located.

[0260] Optionally, the symbol where the SSB is located in the embodiments of the present application includes the symbol where at least one of the following is located:

[0261] B11, secondary synchronisation signals (SSS);

[0262] B12, Primary synchronization signal (PSS);

[0263] B13, Physical broadcast channel (PBCH).

[0264] Optionally, in one implementation manner, the method further includes:

[0265] Determining the first SBFD symbol based on the subcarrier spacing of the SSB and the subcarrier spacing of the activated bandwidth part (BWP);

[0266] Wherein, the activated BWP is an activated uplink BWP and / or an activated downlink BWP.

[0267] It should be noted that the symbol where the SSB is located is determined according to four consecutive symbols where the SSB is located. When the subcarrier spacing of the SSB is the same as that of the activated BWP, the first SBFD symbol and the SSB symbol are aligned in the time domain. When the subcarrier spacing of the SSB is different from that of the activated BWP, the first SBFD symbol needs to be determined according to the subcarrier spacing of the SSB and the subcarrier spacing of the activated BWP. For example, the first SBFD symbol is four consecutive symbols * 2 SCS _ BWP -SCS _ SSB symbols, where SCS_BWP represents the subcarrier spacing of the activated BWP, and SCS_SSB represents the subcarrier spacing of the SSB.

[0268] It should be noted that, optionally, in one implementation, determining whether the first SBFD symbol is valid may not consider whether the activated uplink BWP and / or the activated downlink BWP includes the frequency domain position where the SSB is located. In this way, from the perspective of the network device, the validity of the first SBFD symbol is unified, and the state of whether the first SBFD symbol is valid determined by different terminals will not be different, that is, some terminals determine that the first SBFD symbol is valid, while some terminals determine that the first SBFD symbol is not valid.

[0269] Optionally, in another implementation, determining whether the first SBFD symbol is valid may also be applicable only when the activated BWP includes the frequency domain position where the SSB is located, that is, the specific implementation of determining whether the first sub-band full-duplex SBFD symbol is valid includes:

[0270] If the activated BWP includes the frequency domain position where the SSB is located, determine whether the first SBFD symbol is valid;

[0271] wherein, the activated BWP is the activated uplink BWP and / or the activated downlink BWP.

[0272] That is to say, determining whether the first SBFD symbol is valid is only applicable when the activated uplink BWP and / or the activated downlink BWP includes the frequency domain position where the SSB is located. For the activated uplink BWP and / or the activated downlink BWP that does not include the frequency domain position where the SSB is located, the first SBFD symbol is valid, which will result in different terminals determining different states of whether the first SBFD symbol is valid, that is, some terminals are valid on the first SBFD symbol, while some terminals are not valid on the first SBFD symbol.

[0273] It should be noted that through the above specific solution for whether the first SBFD symbol takes effect, it is possible to support or not support uplink transmission on the SSB symbol configured as the SBFD symbol. As described above, when the first SBFD symbol takes effect, it is possible to support or not support uplink transmission on the SSB symbol configured as the SBFD symbol; when the first SBFD symbol does not take effect, it is possible to not support uplink transmission on the SSB symbol configured as the SBFD symbol.

[0274] Optionally, in one implementation, determining whether the first sub-band full-duplex (SBFD) symbol takes effect includes at least one of the following:

[0275] C11. Determine whether the first SBFD symbol takes effect according to the protocol regulations;

[0276] It should be noted that in this case, it means that whether the first SBFD symbol takes effect is stipulated by the protocol, and both the terminal and the network device can know it according to the protocol regulations.

[0277] That is, the network device and the terminal determine whether the first SBFD symbol is valid or not according to the protocol provisions. Optionally, the above provisions can be applied to CD-SSB and NCD-SSB, or the first SBFD symbol can be specified to be valid or invalid for CD-SSB and NCD-SSB respectively. 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 invalid 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 invalid, serious cross-interference will be introduced. Therefore, for CD-SSB, the first SBFD symbol is specified to be invalid; for NCD-SSB, the first SBFD symbol is specified to be valid. For example, for the UE in the serving cell, the time domain and frequency domain positions of the CD-SSB are known, but for some UEs, the positions of the NCD-SSB may not be known. If the SBFD configuration configured on the NCD-SSB symbol is specified to be invalid, the base station also needs to notify the UE of the position of the NCD-SSB. To avoid the signaling overhead caused thereby, it can be considered that for CD-SSB, the first SBFD symbol is specified to be invalid; for NCD-SSB, the first SBFD symbol is specified to be valid. For example, considering that the CD-SSB carries the configuration information of CORESET#0 associated with SIB1, the terminal obtains the system message according to CORESET#0 associated with SIB1 and then accesses the cell, while the NCD-SSB cannot implement the functions of the above CD-SSB. At the same time, considering the randomness of initial access to the cell through the CD-SSB and the fact that the base station cannot predict this behavior and thus cannot take measures to protect such behavior from uplink transmission interference, therefore, for CD-SSB, the first SBFD symbol is specified to be invalid; for NCD-SSB, the first SBFD symbol is specified to be valid.

[0278] For example, the protocol stipulates that the SBFD symbol configured on the symbol where the SSB is located is valid. Further, it is stipulated that the uplink sub-bands on the SBFD symbol can transmit uplink, or it is stipulated that the uplink sub-bands on the SBFD symbol cannot transmit uplink.

[0279] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is invalid, which means that the SBFD symbol configured on the symbol where the SSB is located is valid.

[0280] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is invalid, and does not stipulate that the uplink sub-bands on the symbol where the SSB is located cannot transmit uplink, which means that the SBFD symbol configured on the symbol where the SSB is located is valid and can transmit uplink.

[0281] For example, the protocol does not stipulate that the SBFD symbol configured on the symbol where the SSB is located is ineffective, and it stipulates that the uplink sub-band on the symbol where the SSB is located cannot transmit uplink, which means that the SBFD symbol configured on the symbol where the SSB is located is effective but cannot transmit uplink.

[0282] For example, the protocol stipulates that the SBFD symbol configured on the symbol where the SSB is located is ineffective, and the protocol stipulates whether it is A11, A12 or A13 that is specifically used.

[0283] C12. Determine whether the first SBFD symbol is effective according to the indication signaling sent by the network device, where the indication signaling is used to indicate whether the first SBFD symbol is effective;

[0284] It should be noted that this situation means that whether the first SBFD symbol is effective is determined by the network device and indicated to the terminal through the indication signaling.

[0285] That is to say, the network device indicates to the terminal whether the first SBFD symbol in the SBFD configuration is effective through signaling. For example, the signaling indicates two states, namely the effective state and the ineffective state. Optionally, 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 indicates to the terminal whether the SBFD symbol configured on the CD-SSB symbol is effective through the first signaling, and indicates to the terminal whether the SBFD symbol configured on the NCD-SSB symbol is effective through the second signaling. Optionally, 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.

[0286] It should be noted that the indication signaling can be carried in the cell common message (such as in SIB), or can be sent through the RRC signaling dedicated to the terminal.

[0287] C13. Determine whether the first SBFD symbol is effective according to the number of times of switching between the SBFD symbol and the non-SBFD symbol;

[0288] It should be noted that in this case, whether the first SBFD symbol is effective is determined based on the number of times of switching between the SBFD symbol and the non-SBFD symbol, and the terminal and the network device use the same rule to determine to ensure the consistency of understanding between the terminal and the network device side.

[0289] It should be noted that the switching between the SBFD symbol and the non-SBFD symbol includes: the switching from the SBFD symbol to the non-SBFD symbol, and / or the switching from the non-SBFD symbol to the SBFD symbol.

[0290] Optionally, in one implementation, the specific implementation of determining whether the first SBFD symbol is effective according to the number of times of switching between the SBFD symbol and the non-SBFD symbol includes at least one of the following:

[0291] C131. If the first number of times of switching between the SBFD symbol and the non-SBFD symbol is greater than and / or equal to the first threshold value, determine that the first SBFD symbol is effective;

[0292] It should be noted that the first threshold value can be specified by the protocol or configured by the network device.

[0293] In this case, it can be considered that as long as the number of times of switching between the SBFD symbol and the non-SBFD symbol is greater than and / or equal to the first threshold value within the time unit, it is considered that the first SBFD symbol is effective.

[0294] Optionally, the time unit can be the SBFD configuration period, or the time unit can also be a period related to the SBFD configuration.

[0295] It should be noted that the greater than and / or equal to here mainly includes greater than (corresponding to the mathematical symbol >) and greater than or equal to (corresponding to the mathematical symbol ≥).

[0296] C132. If the first number of times of switching between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold value, determine that the first SBFD symbol is not effective;

[0297] In this case, it can be considered that within the time unit, if the number of times of switching between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold value, it is considered that the first SBFD symbol is effective.

[0298] Optionally, the time unit can be the SBFD configuration period, or the time unit can also be a period related to the SBFD configuration.

[0299] It should be noted that the less than and / or equal to here mainly includes less than (corresponding to the mathematical symbol <) and less than or equal to (corresponding to the mathematical symbol ≤).

[0300] It should be noted here that if in C131 the first number of times of switching is greater than the first threshold value, then in C132 the first number of times of switching is less than or equal to the first threshold value; if in C131 the first number of times of switching is greater than or equal to the first threshold value, then in C132 the first number of times of switching is less than the first threshold value.

[0301] C133. If the first switching count between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold value, determine the second switching count between the SBFD symbol and the non-SBFD symbol when it is determined that the first SBFD symbol is not valid. If the second switching count is greater than and / or equal to the first threshold value, determine that the first SBFD symbol is valid. If the second switching count is less than and / or equal to the first threshold value, determine that the first SBFD symbol is not valid;

[0302] In this case, it can be considered that within a time unit, if the switching count between the SBFD symbol and the non-SBFD symbol is less than and / or equal to the first threshold value, the first SBFD symbol is tentatively considered not valid first. Then, based on the assumption that the first SBFD symbol is not valid, the switching count between the SBFD symbol and the non-SBFD symbol within the time unit is determined again. As long as the re-determined switching count is greater than and / or equal to the first threshold value, it is finally considered that the first SBFD symbol is valid; otherwise, it is considered that the first SBFD symbol is not valid.

[0303] Optionally, the time unit can be the SBFD configuration period, or the time unit can also be a period related to the SBFD configuration.

[0304] It should be noted that this solution can avoid the switching count between the SBFD symbol and the non-SBFD symbol within the time unit (such as the SBFD configuration period) being greater than the first threshold value due to the invalidity of the first symbol.

[0305] For example, if the number of conversions from SBFD symbols to non-SBFD symbols and the number of conversions from non-SBFD symbols to SBFD symbols within the SBFD configuration period are greater than or equal to N, the first SBFD symbol becomes effective; otherwise, it is necessary to determine whether the number of handovers within the SBFD configuration period after applying A11, A12, or A13 where the first SBFD symbol is ineffective is greater than N. If it is greater than N, the first SBFD symbol becomes effective. If it is less than or equal to N, then A11, A12, or A13 where the first SBFD symbol is ineffective is adopted, where A13 can be a solution based on A131, a solution based on A132, or a solution based on both A131 and A132. Here, N is a predefined value or a value configured by the network device, and N is an integer. For example, N = 2. Optionally, the network device and the terminal determine whether to determine the second SBFD symbol according to A131, or according to both A131 and A132 based on the number of handovers N. Specifically, when the number of handovers within the SBFD configuration period determined after applying A131 is greater than N, in this case, the second SBFD symbol is not determined according to A131 nor according to both A131 and A132; when the number of handovers within the SBFD configuration period determined after applying A131 is less than or equal to N, and when the number of handovers within the SBFD configuration period determined after applying both A131 and A132 is greater than N, in this case, the second SBFD symbol can be determined according to A131; when the number of handovers within the SBFD configuration period determined after applying both A131 and A132 is less than or equal to N, in this case, the second SBFD symbol can be determined according to both A131 and A132. For example, N = 2, and the number of conversions from SBFD symbols to non-SBFD symbols and the number of conversions from non-SBFD symbols to SBFD symbols 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 ineffective. The SBFD symbol determined according to A131 will introduce 1 handover from the SBFD symbol to the non-SBFD symbol and 1 handover 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, when N = 4, the number of conversions from SBFD symbols to non-SBFD symbols and the number of conversions from non-SBFD symbols to SBFD symbols within the SBFD configuration period are equal to 0. At this time, the network device and the terminal determine that the first SBFD symbol is ineffective. The SBFD symbol determined according to A131 will introduce 1 conversion from the SBFD symbol to the non-SBFD symbol and 1 conversion from the non-SBFD symbol to the SBFD symbol. In this case, if the number of conversions within the SBFD configuration period determined after applying A131 and A132 is less than or equal to 4, the network device and the terminal can determine the second SBFD symbol according to A131 and A132. If the number of conversions within the SBFD configuration period determined after applying A131 and A132 is greater than 4, and the terminal finally determines that there are multiple consecutive symbols of non-SSB with configured SBFD symbols according to A132, 2 conversion times can be introduced according to the application of A132. According to the rule from the front to the back in terms of time position and the N value, determine that one or more consecutive symbols of non-SSB with configured SBFD symbols are the second SBFD symbols.
