[0049] Embodiments of the present disclosure provide a communication method, a terminal, a network device, and a storage medium.

[0050] In a first aspect, an embodiment of the present disclosure provides a communication method, which is executed by a terminal and includes:

[0051] Determine overlap between resources in the first resource set and a sub-band full-duplex (SBFD) time unit;

[0052] Among them, the first resource set includes at least one first resource; the first resource is the time domain resource and / or frequency domain resource where the synchronization broadcast block SSB is located.

[0053] In the above embodiment, since the terminal determines that the resources in the first resource set overlap with the sub-band full-duplex SBFD time unit, the terminal can receive SSB on the SBFD time unit and can also perform uplink transmission on the SBFD time unit at the same time. Compared with the situation where SSB can only be received on the SBFD time unit, the resource utilization efficiency can be improved.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0055] Determining, according to a predetermined protocol rule, that resources in the first resource set and the SBFD time unit can overlap;

[0056] Receive configuration information; and determine, based on the configuration information, whether resources in the first resource set can overlap with the SBFD time unit.

[0057] In the above embodiment, the terminal may determine, according to a predetermined protocol rule or configuration information, that the resources in the first resource set and the SBFD time unit can overlap, and the determination method is more flexible.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0059] receiving a first message;

[0060] The first information is used to determine the first resource set, and the time domain positions of the resources in the first resource set overlap with the SBFD time unit.

[0061] In the above embodiment, since the first information can be used to determine the first resource set, and the time domain position of the resources in the first resource set overlaps with the SBFD time unit, after the terminal receives the first information, it can use the resources in the first resource set to perform corresponding transmission operations.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0063] A first signaling is received, where the first signaling indicates that a downlink (DL) time unit is configured as the SBFD time unit.

[0064] In the above embodiment, the downlink DL time unit may be configured as the SBFD time unit through the first signaling.

[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0066] It is not expected that the SBFD time unit included in the first resource is configured as an uplink UL time unit;

[0067] It is undesirable that the first resource includes SBFD time units and non-SBFD time units.

[0068] In the above embodiment, when the terminal does not expect the SBFD time unit contained in the first resource to be configured as an uplink UL time unit, the network device may not configure the SBFD time unit contained in the first resource as an uplink UL time unit; when the terminal does not expect the first resource to include SBFD time units and non-SBFD time units, the network device may not configure the first resource to include SBFD time units and non-SBFD time units.

[0070] It is not expected to receive a second signaling; wherein the second signaling is used to configure the SBFD time unit included in the first resource as a UL time unit.

[0071] In the above embodiment, when the terminal does not expect the second signaling, the network device may not configure the SBFD time unit included in the first resource as a UL time unit through the second signaling.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0073] It is not expected that the frequency domain resource of the first resource overlaps with the SBFD time unit outside the DL transmission frequency domain range.

[0074] In the above embodiment, when the terminal does not expect the frequency domain resources of the first resource to overlap with the SBFD time unit outside the DL transmission frequency domain range, the network device will not configure the frequency domain resources of the first resource to overlap with the SBFD time unit outside the DL transmission frequency domain range.

[0075] In conjunction with some embodiments of the first aspect, in some embodiments, the frequency domain resource where the first resource is not desired overlaps with the SBFD time unit outside the DL transmission frequency domain range, including:

[0076] It is determined that the first resource includes the SBFD time unit, and it is not expected that the frequency domain resource of the first resource overlaps with the SBFD time unit outside the DL transmission frequency domain range.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0185] To better understand the embodiments of the present disclosure, the following examples illustrate relevant scenarios:

[0186] In order to improve uplink (UL) coverage and throughput, duplex enhancement (duplex enhancement) has been studied on subband full duplex (SBFD).

[0187] In some embodiments, a carrier component (CC) on a downlink (DL) or flexible (F) symbol is divided into multiple subbands (SBs) in the frequency domain. The multiple SBs include one UL subband and at least one (one or two) DL subbands. A base station can transmit DL signals on the DL subband and simultaneously receive UL signals on the UL subband. DL or F symbols can be configured in at least one of the following ways:

[0188] TDD-UL-DL-ConfigCommon configuration;

[0189] TDD-UL-DL-ConfigDedicated configuration;

[0190] TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated configurations; and

[0191] Downlink control information format 2-0 (DCI format 2-0) indication.

[0192] When a symbol includes both a DL subband and a UL subband in the frequency domain, it may be called an SBFD symbol.

[0193] In some embodiments, when a time slot includes at least one SBFD symbol among multiple symbols, the time slot may be called an SBFD time slot, referring to Figure 1b, time slot 0 is a DL time slot, including 14 DL symbols, time slots 1 to 3 are SBFD time slots, each time slot includes 14 SBFD symbols, and time slot 4 is a UL time slot, including 14 UL symbols.

[0194] In some embodiments, a DL or F symbol can be configured as SBFD via semi-static signaling, referred to as semi-static SBFD. Alternatively, a DL or F symbol can be dynamically signaled as SBFD, referred to as dynamic SBFD. Furthermore, an SBFD symbol can be modified to a DL, UL, or F symbol via dynamic signaling.

[0195] In some embodiments, a guard band (GB) may exist between the DL sub-band and the UL sub-band to reduce interference between DL signals in the DL sub-band and UL signals in the UL sub-band through frequency domain isolation.

[0196] In some embodiments, in the SBFD symbol, the frequency domain range that can be used for DL ​​transmission includes the following two cases: 1. GB and UL subbands are not available for DL ​​transmission, and DL subbands can be used for DL ​​transmission; 2. UL subbands are not available for DL ​​transmission, and DL subbands and GBs can be used for DL ​​transmission.

[0197] In some embodiments, in an SBFD symbol, the frequency domain range that can be used for DL ​​transmission may be referred to as a DL transmission frequency domain range, and the frequency domain range that cannot be used for DL ​​transmission may be referred to as outside the DL transmission frequency domain range. According to the above analysis, the DL transmission frequency domain ranges of non-SBFD symbols and SBFD symbols are different. The DL transmission frequency domain range is the DL transmission frequency domain range on the CC. In an SBFD symbol, the DL transmission frequency domain range on the DL partial bandwidth (BWP, BandWidth Part) refers to the frequency domain range where the BWP overlaps with the DL transmission frequency domain range on the CC. Unless otherwise specified, the DL transmission frequency domain range in this disclosure refers to the DL transmission frequency domain range on the BWP.

[0198] In some embodiments, when the terminal is in the Radio Resource Control (RRC) idle state, the initial access cell measures the received signal strength of the Synchronization Signal / PBCH block (SSB) beam and other information to select the optimal SSB beam. In SBFD symbols, the base station can transmit downlink signals in the DL SB. Therefore, compared to only being able to configure SSB in DL or F symbols, being able to configure SSB in SBFD symbols can reduce the limitations of SBFD symbol time domain configuration.

[0199] In some embodiments, please refer to Figure 1c, the first SSB in a time slot uses OS#2~5 (such as SSB#0,2,4,6), and the second SSB uses OS#8~11 (such as SSB#1,3,5,7). When the SBFD symbol can be configured with SSB, SBFD can be configured in OS#2~5,8~11 of time slots #0~3, and the configurable time domain position of the SBFD symbol increases.

[0200] However, the relevant conflict handling criteria stipulate that the UE cancels UL signal transmission in the symbol where the SSB is located. If the SSB is located in an SBFD symbol, the UL subband in that symbol cannot be used for UL transmission, resulting in a waste of frequency domain resources in the UL subband. Furthermore, conflict handling between the newly introduced SBFD symbols and SSBs is not considered. Therefore, the conflict handling criteria for SSBs in SBFD symbols need to be updated.

[0201] In some embodiments, see Table 1, which shows how SSB conflicts are handled in different situations:

[0202] Table 1:

[0203] In some embodiments, Dynamic D / U can be DL / UL transmission indicated by DCI; RRC-D / U can be DL / UL transmission configured by RRC; Any-D / U can be RRC-D or Dynamic-D; Semi-D / U can be tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated configured as DL or UL; SFI-D / U can be SFI in DCI format 2-0 indicating DL or UL.

[0204] In some embodiments, please refer to Figure 1d. For method 1, OS#0~6 (OFDM symbol) in time slot #3 is configured as UL through tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and overlaps with the symbol of SSB#6. The UE does not expect this situation to occur.

[0205] In some embodiments, see Figure 1d. For mode 2, OS#7-13 symbols in time slot #3 are indicated as UL through SFI, and overlap with the symbol of SSB#7. The UE does not expect this to happen.

[0206] In some embodiments, please refer to Figure 1d. For mode 3, there is a PUSCH signal transmission in time slot #1, and it overlaps with the symbol where SSB#3 is located, then the UE cancels sending PUSCH; there is an SRS signal transmission in OS#10~13 in time slot #2, and it overlaps with the symbol where SSB#5 is located (OS#8~11), then the UE cancels sending SRS on OS#10~11.

[0207] In some embodiments, collision handling of SSB and SBFD symbols is not considered.

[0208] In some embodiments, when the PUSCH, PUCCH or PRACH signal overlaps with the symbol where the SSB is located, the corresponding PUSCH, PUCCH or PRACH signal transmission is canceled; or, when the SRS signal overlaps with the symbol where the SSB is located, the transmission of the SRS on the overlapping symbol is canceled, which will cause the frequency domain resources of the UL subband on the symbol where the SSB is located to be unusable (method 3).

[0209] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0210] Step S2101: The network device sends first information to the terminal.

[0211] In some embodiments, the terminal receives first information sent by the network device.

[0212] In some embodiments, the terminal determines that resources in the first resource set overlap with the SBFD time unit.

[0213] In some embodiments, the network device determines that resources in the first set of resources overlap with the SBFD time unit.

[0214] In some embodiments, the terminal may determine, based on a predetermined protocol or acquired configuration information, that resources in the first resource set can overlap with the SBFD time unit.

[0215] Exemplarily, before the terminal receives the first information, the terminal may determine, based on a predetermined protocol or configuration information sent by a network device, that resources in the first resource set can overlap with the SBFD time unit.

[0216] In some embodiments, the network device may determine based on a predetermined protocol that resources in the first resource set can overlap with the SBFD time unit, or the network device may configure resources in the first resource set to overlap with the SBFD time unit.

[0217] Exemplarily, before the network device sends the first information, the network device may determine based on a predetermined protocol that resources in the first resource set can overlap with the SBFD time unit, or the network device may configure resources in the first resource set to overlap with the SBFD time unit.

[0218] In some embodiments, the time unit may be a symbol, a time slot, a subframe, etc., which is not limited herein. Exemplarily, the time unit is a symbol.

[0219] In some embodiments, each time unit corresponds to a time-frequency domain position.

[0220] In some embodiments, the first resource set includes at least one first resource.

[0221] In some embodiments, each first resource corresponds to a time-frequency domain position.

[0222] In some embodiments, the first resource is a time domain resource and / or a frequency domain resource where the synchronization broadcast block SSB is located.

[0223] In some embodiments, the overlapping of resources may be an overlapping of time domain resources and / or frequency domain resources.

[0224] In some embodiments, the terminal receives configuration information sent by a network device; and the terminal determines, based on the configuration information, that resources in the first resource set can overlap with the SBFD time unit.

[0225] In some embodiments, according to a predetermined protocol rule, the terminal and the network device determine that resources in the first resource set can overlap with the SBFD time unit.

[0226] In some embodiments, the first information is used to determine the first set of resources.

[0227] In some embodiments, the time domain locations of the resources in the first resource set overlap with the SBFD time unit.

[0228] In some embodiments, the first information is SSB configuration information.

[0229] In some embodiments, the terminal determines the time-frequency domain position of the SSB within the configuration period of the SSB configuration information.

[0230] In some embodiments, the terminal can determine the time-frequency domain position of the actually received SSB based on the first information.

[0231] Step S2102: The network device sends a first signaling to the terminal.

[0232] In some embodiments, the terminal receives first signaling sent by the network device.

[0233] In some embodiments, the terminal receives first signaling sent by a network device, where the first signaling indicates that a downlink (DL) time unit is configured as the SBFD time unit.

[0234] Exemplarily, the DL symbols are configured as SBFD symbols through semi-static signaling or dynamically indicated as SBFD symbols.

[0235] Exemplarily, DL symbols may be configured through tdd-UL-DL-ConfigurationCommon signaling.

[0236] Exemplarily, DL symbols may be configured through tdd-UL-DL-ConfigurationDedicated signaling.

[0237] For example, DL symbols may be dynamically indicated through DCI format 2-0 signaling.

[0238] In some embodiments, the terminal does not expect the SBFD time units included in the first resource to be configured as UL time units.

[0239] Exemplarily, the terminal does not expect the SBFD symbol included in the symbol where the SSB is located to be configured as a UL symbol.

[0240] In some embodiments, the terminal does not expect the first resource to include SBFD time units and non-SBFD time units.

[0241] For example, one SSB transmission cannot span SBFD and non-SBFD symbols.

[0242] Exemplarily, the terminal does not expect that a symbol where an SSB is located contains both SBFD and non-SBFD symbols.

[0243] In some embodiments, the terminal does not expect to receive second signaling, wherein the second signaling is used to configure the SBFD time unit included in the first resource as a UL time unit. In this way, the situation where the SSB cannot be received after the SBFD is configured as a UL time unit can be reduced, and the SSB can be received on the SBFD.

[0244] In some embodiments, it is undesirable that the frequency domain resource of the first resource overlaps with the SBFD time unit outside the DL transmission frequency domain range.

[0245] In some embodiments, it is determined that the first resource includes the SBFD time unit, and it is not expected that the frequency domain resource of the first resource overlaps with the SBFD time unit outside the DL transmission frequency domain range.

[0246] In some embodiments, when the symbol where the SSB is located includes an SBFD symbol, the terminal does not expect the frequency domain range of the SSB to overlap with the SBFD symbol outside the DL transmission frequency domain range.

[0247] In some embodiments, the first signaling is semi-static signaling or dynamic signaling, and / or the second signaling is semi-static signaling or dynamic signaling.

[0248] In some embodiments, the semi-static signaling is SBFD symbol configuration signaling.

[0249] In some embodiments, the dynamic signaling is downlink control information DCI signaling.

[0250] Exemplarily, see 2b, the first SSB in a time slot uses OS#2~5 (such as SSB#0, 2, 4, 6), and the second SSB uses OS#8~11 (such as SSB#1, 3, 5, 7); exemplarily, the terminal does not expect the SBFD symbols in OS#2~5 and OS#8~11 in time slot #3 to be statically configured as UL or dynamically indicated as UL. It should be noted that if the SBFD symbol is configured as UL, there will be no DL symbol for SSB reception in the corresponding time slot. In the present disclosure, since the terminal does not expect to receive the second signaling, the network device may not configure the SBFD as UL through the second signaling, so that the terminal can receive SSB on SBFD. Exemplarily, the terminal does not expect the SSB in the SBFD symbol to overlap with the SBFD symbol outside the DL transmission frequency domain, such as not expecting SSB#1~7 to overlap with the SBFD symbol outside the DL transmission frequency domain.

[0251] It should be noted that the execution order of step S2101 and step S2102 is not limited, and step S2101 can be executed first, or step S2102 can be executed first. Of course, the configuration signaling of the first information in step S2101 can also be the first signaling in step S2102, that is, step S2101 and step S2102 can be implemented through the same signaling, for example, RRC signaling.

[0252] Step S2103: The network device sends signaling to the terminal.

[0253] In some embodiments, the network device sends a third signaling to the terminal, where the third signaling is used to configure the first type of SSB.

[0254] In some embodiments, the network device sends a fourth signaling to the terminal, where the fourth signaling is used to configure the second type of SSB.

[0255] In some embodiments, the third signaling and the fourth signaling are the same signaling or different signaling.

[0256] In some embodiments, a first type of SSB and a second type of SSB among the SSBs are determined.

[0257] In some embodiments, the first type of SSB is the SSB actually received among the SSBs.

[0258] In some embodiments, the second type of SSB is an SSB other than the first type of SSB among the SSBs.

[0259] In some embodiments, the SSB set includes at least two SSBs, which may be referred to as nominal SSBs.

[0260] In some embodiments, the SSB used for actual reception in the SSB set is called an actual SSB.

[0261] In some embodiments, SSBs other than the actual SSBs in the SSB set are referred to as non-actual SSBs.

[0262] In some embodiments, a third signaling is received, wherein the third signaling is used to configure a nominal SSB. Exemplarily, the nominal SSB is configured via an information element ssb-PositionsInBurst.

[0263] In some embodiments, third signaling is received, where the third signaling is used to configure the first type SSB.

[0264] In some embodiments, a fourth signaling is received, where the fourth signaling is used to configure the second type of SSB. Exemplarily, the actual SSB is configured via information elements SSB-MTC and ssb-ToMeasure.

[0265] Step S2104: The terminal performs processing operations.

[0266] In some embodiments, for the first type of SSB, it is determined that the first resource overlaps with a time unit for transmitting an uplink UL signal, and the UL signal transmission is canceled.

[0267] In some embodiments, for the first type of SSB, it is determined that the first resource overlaps with a time unit for transmitting an uplink UL signal, and the UL signal transmission can be canceled in a first manner.

[0268] In some embodiments, the first method may be: the symbol where the SSB is located overlaps with the symbol where the UL signal is located, and the PUSCH, PUCCH and / or PRACH signal transmission is canceled or the SRS signal transmission on the overlapping symbol is canceled.

[0269] In some embodiments, for the first type SSB, it is determined that the time unit where the first resource is located is an SBFD time unit, and the first resource overlaps with the time unit for sending a UL signal, and the UL signal is sent.

[0270] In some embodiments, for the first type SSB, it is determined that the time unit where the first resource is located is an SBFD time unit, and the first resource overlaps with the time unit for sending the UL signal, and the UL signal can be sent in the second manner.

[0271] In some embodiments, the second method may be: determining that the time unit where the first resource is located is an SBFD time unit, and the first resource overlaps with the time unit for sending UL signals, and sending PUSCH, PUCCH and / or PRACH signals or SRS signals on overlapping symbols.

[0272] In some embodiments, the UL signal includes at least one of the following:

[0273] Physical uplink shared channel PUSCH signal;

[0274] Physical uplink control channel PUCCH signal;

[0275] Physical Random Access Channel PRACH signal;

[0276] Sounding Reference Signal SRS.

[0277] In some embodiments, for the second type of SSB, it is determined that the time unit where the first resource is located is an SBFD time unit, and the first resource overlaps with the time unit for sending a UL signal, and the UL signal is sent.

[0278] For example, referring to Figure 2c, the first SSB in a time slot uses OS#2~5 (such as SSB#0, 2, 4, 6), the second SSB uses OS#8~11 (such as SSB#1, 3, 5, 7), PUSCH#1 and SRS#1 use OS#0~3, and PUSCH#2 and SRS#2 use OS#10~13.

[0279] Exemplarily, for the first type of SSB, corresponding to SSB #3 and #5 in FIG2c , the transmission of PUSCH #2 is canceled, and the transmission of SRS #2 on OS #10 to 11 is canceled.

[0280] Exemplarily, for the first type of SSB, corresponding to SSB #3 and #5 in FIG2c , PUSCH #2 and SRS #2 are transmitted in OS #10 to 13.

[0281] Exemplarily: for the second type of SSB, corresponding to SSB #2 and #4 in Figure 2c, PUSCH #1 and SRS #1 are sent in OS #0~3.

[0282] In some embodiments, the time unit where the first resource is located is SBFD, and the first resource overlaps with the time unit for sending a UL signal, and the UL signal is sent.

[0283] In some embodiments, the sending of the UL signal includes: sending the UL signal based on a priority of the UL signal.

[0284] For example, please refer to FIG. 2C again. When PUSCH#2 is a high-priority UL signal, PUSCH#2 is transmitted in OS#10-13; when SRS#2 is a high-priority UL signal, SRS#2 is transmitted in OS#10-13.

[0285] For example, please refer to Figure 2c again. For example: when PUSCH#1 is a high priority UL signal, PUSCH#1 is sent in OS#0~3; when SRS#1 is a high priority UL signal, SRS#1 is sent in OS#0~3.

[0286] In some embodiments, the sending of the UL signal based on the priority of the UL signal includes:

[0287] Sending the UL signal of high priority, wherein the UL signal of high priority includes at least one of the following:

[0288] UL signal indicated by DCI;

[0289] UL low-latency and highly reliable communication URLLC signal.

[0290] In some embodiments, canceling the transmission of the UL signal may be canceling the transmission of a low-priority UL signal.

[0291] In some embodiments, for multiple PUSCH transmissions indicated by a DCI, the high-priority UL signal refers to the first PUSCH transmission, including at least one of the following:

[0292] Dynamic Grant (DG) - PUSCH repeated type A transmission (with or without valid slot count);

[0293] Type 2 Configuration Grant (CG) - PUSCH repeated Type A transmission (with or without valid slot count);

[0294] Type 2CG - PUSCH transmission without duplication;

[0295] Multiple PUSCH transmissions scheduled by a single DCI;

[0296] With or without repeated TboMS transmissions.

[0297] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0298] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0409] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

[0410] Figure 6a is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in Figure 6a, the embodiment of the present disclosure relates to a communication method, which is executed by a communication system. The method includes:

[0411] Step S6101: Receive first information, the first information including SSB configuration information, and determine the time-frequency position of the SSB within the configuration period of the SSB based on the SSB configuration information.

[0412] In one embodiment, the first configuration information may determine the time-frequency position of the actually received SSB.

[0413] Step S6102: Determine the conflict handling between SSB and UL signal, symbol category, etc. according to the SSB time-frequency position.

[0414] In some embodiments, solution 1 is provided: conflicting updates of symbol direction configuration and SSB.

[0415] In some embodiments, Scheme 1-1 is provided:

[0416] In some embodiments, the time domain:

[0417] Exemplarily, the DL symbol is configured as tdd-UL-DL-ConfigurationCommon.

[0418] Exemplarily, the DL symbol is configured as tdd-UL-DL-ConfigurationDedicated.

[0419] Exemplarily, the DL symbol is indicated by DCI format 2-0.

[0420] For example, the UE does not expect the symbol where the SSB is located, and the dynamic signaling indicates that an SBFD symbol is a UL symbol.

[0421] For example, the UE does not expect the symbol where the SSB is located, and semi-static signaling configures an SBFD symbol as a UL symbol.

[0422] In some embodiments, one SSB transmission cannot span SBFD and non-SBFD symbols.

[0423] In some embodiments, the UE does not expect a symbol where an SSB is located to contain both SBFD and non-SBFD symbols.

[0424] In some embodiments, the frequency domain:

[0425] Exemplarily, when the symbol where the SSB is located includes an SBFD symbol, it is not expected that the frequency domain range of the SSB overlaps with the SBFD symbol outside the DL transmission frequency domain range.

[0426] Exemplarily, the SBFD symbol is configured through semi-static signaling and / or indicated by dynamic signaling.

[0427] For example, referring to FIG2b , the first SSB in a time slot uses OS#2 to 5 (such as SSB#0, 2, 4, 6), and the second SSB uses OS#8 to 11 (such as SSB#1, 3, 5, 7).

[0428] Exemplarily, the UE does not expect the SBFD symbols in OS#2-5 and OS#8-11 in time slot #3 to be statically configured as UL or dynamically indicated as UL.

[0429] □ Exemplarily, the UE does not expect the SSB in the SBFD symbol to overlap with the SBFD symbol outside the DL transmission frequency domain, for example, the UE does not expect SSB#1 to 7 to overlap with the SBFD symbol outside the DL transmission frequency domain.

[0430] In some embodiments, a solution 2 is provided: UL signal and SSB conflict.

[0431] In some embodiments, a solution 2-1 is provided: the actually received SSBs (which may be referred to as actual SSBs) in the configured SSB set (which may be referred to as nominal SSBs) are configured, and the SSBs other than the actual SSBs in the nominal SSBs are non-actual SSBs:

[0432] In some embodiments, the configuration is actual SSB.

[0433] Exemplarily, the symbol where the actual SSB is located overlaps with the UL signal, and the UL signal transmission is canceled according to the first method.

[0434] Exemplarily, the symbol where the actual SSB is located is SBFD, and the symbol where the actual SSB is located overlaps with the UL signal.

[0435] For example, the UE may send a UL signal.

[0436] For example, the UE may send a high priority UL signal.

[0437] In one embodiment, the non-actual SSB, the symbol where the non-actual SSB is located is SBFD, and the symbol where the non-actual SSB is located overlaps with the UL signal.

[0438] For example, the UE may send a UL signal.

[0439] For example, the UE may send a high priority UL signal

[0440] In some embodiments, the nominal SSB is configured via the information element ssb-PositionsInBurst, and the actual SSB is configured via the information elements SSB-MTC and ssb-ToMeasure.

[0441] In some embodiments, the first method is: the symbol where the SSB is located overlaps with the UL signal, and the PUSCH, PUCCH and / or PRACH signal transmission is canceled or the SRS signal transmission on the overlapping symbol is canceled.

[0442] Please refer to Figure 2c. The first SSB in a time slot uses OS#2 to 5 (such as SSB#0, 2, 4, 6), the second SSB uses OS#8 to 11 (such as SSB#1, 3, 5, 7), PUSCH#1 and SRS#1 use OS#0 to 3, and PUSCH#2 and SRS#2 use OS#10 to 13.

[0443] Exemplarily, the transmission of PUSCH#2 is canceled, and the transmission of SRS#2 on OS#10-11 is canceled.

[0444] For example, PUSCH#2 and SRS#2 are transmitted in OS#10-13.

[0445] Exemplarily, when PUSCH#2 is a high-priority UL signal, PUSCH#2 is transmitted in OS#10-13; when SRS#2 is a high-priority UL signal, SRS#2 is transmitted in OS#10-13.

[0446] For example, PUSCH#1 and SRS#1 are transmitted in OS#0-3.

[0447] Exemplarily, when PUSCH#1 is a high-priority UL signal, PUSCH#1 is transmitted in OS#0-3; when SRS#1 is a high-priority UL signal, SRS#1 is transmitted in OS#0-3.

[0448] In some embodiments, a solution 2-2 is provided: the symbol where the SSB is located is SBFD, and the symbol where the SSB is located overlaps with the UL signal:

[0449] For example, the UE may send a UL signal.

[0450] For example, the UE may send a high priority UL signal.

[0451] In some embodiments, the high priority UL signal includes:

[0452] UL signal indicated by DCI;

[0453] UL URLLC signal.

[0454] In one embodiment, for multiple PUSCH transmissions indicated by a DCI, the high-priority UL signal refers to the first PUSCH transmission, including at least one of the following:

[0455] DG (Dynamic Grant, dynamic authorization)-PUSCH repetition type A with / without available slot counting;

[0456] Type 2 CG (Configured grant, configuration authorization)-PUSCH repetition type A with / without available slot counting;

[0457] Type 2 CG-PUSCH without repetition;

[0458] Multiple PUSCH scheduled by single DCI;

[0459] TBoMS with / without repetition.
