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

[0260] To better understand the embodiments of the present disclosure, the following examples illustrate relevant scenarios:

[0261] In order to improve uplink (UL) coverage and throughput, duplex enhancement (duplex enhancement) has been studied on subband full duplex (SBFD).

[0262] In some embodiments, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on a downlink (DL) symbol or a flexible (F) symbol. 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. The DL or F symbols can be configured in at least one of the following ways:

[0263] TDD-UL-DL-ConfigCommon configuration;

[0264] TDD-UL-DL-ConfigDedicated configuration;

[0265] TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated configurations; and

[0266] Downlink control information format 2-0 (DCI format 2-0) indication.

[0267] When a symbol includes both a DL subband and a UL subband in the frequency domain, it may be called an SBFD symbol.

[0268] 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.

[0269] 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.

[0270] 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.

[0271] In some embodiments, in an SBFD symbol, the frequency domain range available for UL transmission may be discontinuous, including the following two cases: 1. The GB and DL subbands are not available for UL transmission, and the UL subbands can be used for UL transmission; 2. The DL subbands are not available for UL transmission, and the UL subbands and GBs can be used for UL transmission.

[0272] In some embodiments, in an SBFD symbol, the frequency domain range that can be used for UL transmission can be referred to as the UL frequency domain range, and the frequency domain range that cannot be used for UL transmission can be referred to as outside the UL frequency domain range. Based on the above analysis, it can be seen that the UL frequency domain ranges of non-SBFD symbols and SBFD symbols are different. The UL frequency domain range is the UL frequency domain range on the CC. In an SBFD symbol, the UL frequency domain range on the UL bandwidth part (BWP) refers to the frequency domain range where the BWP overlaps with the UL frequency domain range on the CC. Unless otherwise specified, the UL frequency domain range in this disclosure refers to the UL frequency domain range on the BWP.

[0273] In some embodiments, when the terminal is in the Radio Resource Control (RRC) idle state, the terminal in the initially accessed cell will measure information such as the received signal strength of the synchronization broadcast block (SSB) beam and select the optimal SSB beam. In the direction of the optimal SSB beam, a physical random access channel (PRACH) signal is sent at the random access channel occasion (RO) for random access. In addition, in other states, the terminal may also send a PRACH signal at the RO for random access. Random access includes contention-based random access (CBRA) and contention-free random access (CFRA). In CBRA, if multiple terminals use the same preamble, random access will fail.

[0274] In some embodiments, the SSB referred to below may be the SSB selected by the UE mentioned above.

[0275] In some embodiments, a UE can transmit uplink signals in UL SB during SBFD symbols. Therefore, configuring POs in SBFD symbols increases the number of POs compared to configuring POs only in UL or F symbols. SBFD-aware UEs (UEs that can recognize SBFD symbol configurations) can perform random access using POs configured in SBFD symbols, reducing access latency and the probability of PUSCH transmission collisions between different UEs in CBRA.

[0276] In some embodiments, referring to FIG. 1 c , a valid PO configured in an SBFD symbol may be referred to as an additional valid PO, and a valid PO in a UL or F symbol may be referred to as a legacy valid PO.

[0277] In some embodiments, after configuring a PO, it is necessary to determine whether a PO is valid. Only valid POs can be used to transmit MsgA-PUSCH signals. As previously mentioned, SBFD symbols and UL symbols have different frequency domains for UL transmission. Furthermore, whether a single MsgA-PUSCH transmission can span both SBFD and non-SBFD symbols is under investigation.

[0278] In some embodiments, determining whether a PO is a valid PO requires considering at least one of the following factors:

[0279] 1. Whether the legacy DL symbol is configured as SBFD;

[0280] 2. Whether the frequency domain range of PO is within the UL subband;

[0281] 3. Whether a valid PO can cross SBFD and non-SBFD symbols.

[0282] In some embodiments, for MsgA-PUSCH time-frequency resource configuration, there are the following embodiments:

[0283] In some embodiments, the time domain configuration may include at least one of the following: msgA-PUSCH-TimeDomainOffset, A information, nrofSlotsMsgA-PUSCH, nrofMsgA-PO-PerSlot, and guardPeriodMsgA-PUSCH.

[0284] In some embodiments, msgA-PUSCH-TimeDomainOffset indicates: the starting time slot of the PUSCH;

[0285] In some embodiments, the A information includes: an offset between the PRACH slot containing the valid RO, using the SCS (Subcarrier Spacing) of the activated active UL BWP, and each PRACH slot containing the valid RO determines the time slot where the PO is located;

[0286] In some embodiments, nrofSlotsMsgA-PUSCH indicates: the number of consecutive time slots containing one or more POs (PUSCH occasions), where the POs of each time slot are located at the same symbol position;

[0287] In some embodiments, nrofMsgA-PO-PerSlot indicates: the number of POs contained in one time slot;

[0288] In some embodiments, guardPeriodMsgA-PUSCH indicates that when a time slot contains multiple POs in the time domain, the POs are separated by guardPeriod symbol lengths.

[0289] In some embodiments, the frequency domain configuration may be determined based on whether Interlaced PUSCH is configured.

[0290] In some embodiments, if Interlaced PUSCH is configured, the frequency domain range may be determined based on at least one of the following:

[0291] 1. interlaceIndexFirstPO-MsgA-PUSCH indicates the first interlace index;

[0292] 2. nrofInterlacesPerMsgA-PO indicates the number of interlaces;

[0293] 3. A CRB contained in an Interlace.

[0294] In some embodiments, if Interlaced PUSCH is not configured, the frequency domain range may be determined based on at least one of the following:

[0295] 1. frequencyStartMsgA-PUSCH: PO frequency domain starting position, offset relative to CC PRB0;

[0296] 2. nrofPRBs-PerMsgA-PO: number of RBs in PO;

[0297] 3. nrofMsgA-PO-FDM: the number of FDMeds of PO at the same time domain position;

[0298] 4. guardBandMsgA-PUSCH: The frequency domain interval between adjacent POs at the same time domain position; if staggered PUSCH is configured, guardBandMsgA-PUSCH takes the value of 0;

[0299] 5. Hopping:

[0300] In some embodiments, hopping may include at least one of msgA-IntraSlotFrequencyHopping and msgA-HoppingBits.

[0301] In some embodiments, msgA-IntraSlotFrequencyHopping indicates: whether the PO allows intra-slot hopping;

[0302] In some embodiments, msgA-HoppingBits may be combined with msgA-HoppingBits reference to determine a frequency offset between a 1st hop and a 2nd hop of frequency hopping, where msgA-HoppingBits indicates hopping bits in a table.

[0303] In some embodiments, for the symbol where the PUSCH is located and the mapping type, the mapping type includes Option 1 and Option 2.

[0304] In some embodiments, Option 1 is: determining the symbol and PUSCH mapping type according to msgA-PUSCH-timeDomainAllocation;

[0305] Exemplarily, PUSCH-ConfigCommon->PUSCH-TimeDomainResourceAllocationList is configured.

[0306] As an example, one row in PUSCH-ConfigCommon->PUSCH-TimeDomainResourceAllocationList is used.

[0307] In some embodiments, Option 2 is: determined according to startSymbolAndLengthMsgA-PO and mappingTypeMsgA-PUSCH;

[0308] Exemplarily, in all time slots containing PO, the symbol where the PO is located is the same (ie, the TDRA of each time slot is the same);

[0309] Exemplarily, the UE does not expect overlap in the time domain and / or frequency domain between multiple POs configured in a MsgA-PUSCH-Config.

[0310] In some embodiments, the judgment criteria for valid PO can be determined based on the configuration of tdd-UL-DL-ConfigurationCommon.

[0311] In some embodiments, if tdd-UL-DL-ConfigurationCommon is not configured, the criterion for determining a valid PO may adopt solution 1.

[0312] In some embodiments, solution 1 is: when conditions 1-1, 1-2, and 1-3 are met, the PO is a valid PO;

[0313] Condition 1-1: In a PUSCH slot, the PO does not precede the SSB.

[0314] Condition 1-2: PO is at least Ngap symbols away from the symbol where the previous SSB is located;

[0315] Conditions 1-3: The PO does not overlap with any valid RO in the time domain and / or frequency domain.

[0316] In some embodiments, if the UE is configured with tdd-UL-DL-ConfigurationCommon, the criterion for determining a valid PO may adopt scheme 2.

[0317] In some embodiments, solution 2 is: when conditions 2-1 and 2-4 are met or conditions 2-2, 2-3 and 2-4 are met, PO is a valid PO.

[0318] Condition 2-1: PO is within the UL symbol;

[0319] Condition 2-2: In a PUSCH slot, the PO does not precede the SSB.

[0320] Condition 2-3: The PO is at least Ngap symbols away from the symbol where the previous SSB is located, and the PO is at least Ngap symbols away from the symbol where the previous DL is located;

[0321] Condition 2-4: PO does not overlap with any valid RO in the time domain and / or frequency domain.

[0322] In some embodiments, in the above scheme, Ngap is an integer greater than or equal to 0, and the specific value is determined according to the existing protocol.

[0323] Please refer to Figure 1d, which shows the time domain positions of valid PO and invalid PO.

[0324] It should be noted that the Valid PO determination does not take into account at least one of the following factors:

[0325] 1. Whether the legacy DL symbol is configured as SBFD;

[0326] 2. The frequency domain ranges that SBFD symbols and UL symbols can use for UL transmission are different;

[0327] 3. Whether a valid PO can cross SBFD and non-SBFD symbols.

[0328] 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:

[0329] Step S2101: The network device sends the second information and / or the third information to the terminal.

[0330] In some embodiments, the terminal receives second information sent by the network device.

[0331] In some embodiments, the second information is used to determine the first information.

[0332] In some embodiments, the first information is used to indicate an allowed overlapping relationship between any valid PO and a time unit, where the time unit includes a sub-band full-duplex (SBFD) time unit and / or a non-SBFD time unit.

[0333] In some embodiments, the second information is used to indicate an allowed overlapping relationship between any valid PO and a time unit, where the time unit includes a sub-band full-duplex (SBFD) time unit and / or a non-SBFD time unit.

[0334] In some embodiments, the first information is used to indicate one of the following: any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit; any valid PO is allowed to overlap with both the sub-band full-duplex SBFD time unit and the non-SBFD time unit; any valid PO is only allowed to overlap with the SBFD time unit; any valid PO is only allowed to overlap with the non-SBFD time unit.

[0336] In some embodiments, the second information is used to semi-statically indicate or dynamically indicate one of the following: any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit; any valid PO is allowed to overlap with the sub-band full-duplex SBFD time unit and the non-SBFD time unit at the same time; any valid PO is only allowed to overlap with the SBFD time unit; any valid PO is only allowed to overlap with the non-SBFD time unit.

[0337] In some embodiments, the second information may be determined based on predetermined communication protocol information. Here, the predetermined communication protocol information may be stored in the terminal.

[0338] It should be noted that any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit. It can be understood that any valid PO is allowed to overlap with the SBFD time unit or the non-SBFD time unit, but not both at the same time.

[0339] In some embodiments, dynamic indications may be performed and used in real time.

[0340] In some embodiments, a static indication may require activation through an activation command before use.

[0341] 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.

[0342] In some embodiments, each time unit corresponds to a time domain and / or frequency domain position.

[0343] In some embodiments, the third information is used to indicate configuration parameters of the first PO.

[0344] In some embodiments, the configuration parameters of the first PO include the time-frequency position of the first PO within the configuration period.

[0345] In some embodiments, the configuration parameters corresponding to the frequency domain range of the first PO on the SBFD symbol and the non-SBFD symbol are the same or different.

[0346] In some embodiments, when configuring the time-frequency resources of MsgA-PUSCH for SBFD-aware UE, the frequency domain configuration of MsgA-PUSCH on SBFD symbols and non-SBFD symbols may be configured identically or differently.

[0347] In some embodiments, when MsgA-PUSCH supports intra-slot hopping, PO does not overlap with the outside of the UL subband on the SBFD symbol, which means that the 1st hop does not overlap with the outside of the UL subband on the SBFD symbol and the 2nd hop does not overlap with the outside of the UL subband on the SBFD symbol.

[0348] In some embodiments, PO is within a SBFD symbol or PO is within a non-SBFD symbol means that both the 1st hop and the 2nd hop are within a SBFD symbol or both the 1st hop and the 2nd hop are within a non-SBFD symbol.

[0349] It should be noted that step S2101 may be an optional step.

[0350] Step S2102: The terminal or network device determines the first information.

[0351] In some embodiments, the first information may be determined based on second information and / or third information received from the network device.

[0352] In some embodiments, the first information may be determined based on predetermined communication protocol information. Here, the predetermined communication protocol information may be stored in the terminal. It should be noted that if the first information is determined based on the predetermined communication protocol information, step S2101 may not be performed, that is, step S2101 is not required.

[0353] In some embodiments, the first information is used to indicate one of the following: any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit; any valid PO is allowed to overlap with the sub-band full-duplex SBFD time unit and the non-SBFD time unit at the same time; any valid PO is only allowed to overlap with the SBFD time unit; any valid PO is only allowed to overlap with the non-SBFD time unit.

[0354] It should be noted that any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit. It can be understood that any valid PO is allowed to overlap with the SBFD time unit or the non-SBFD time unit, but not both at the same time.

[0355] Step S2103: The terminal or the network device determines whether the first physical uplink shared channel opportunity PO is a valid PO.

[0356] In some embodiments, based on the first information, the terminal or the network device determines whether the first physical uplink shared channel opportunity PO is a valid PO.

[0357] In some embodiments, based on the first information, the configuration result of the time division duplex uplink and downlink common configuration information and the configuration result of the semi-static SBFD configuration information, the terminal or the network device determines whether the first physical uplink shared channel opportunity PO is a valid PO.

[0358] In some embodiments, the terminal or the network device determines that any one valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit, is not configured with time division duplex uplink and downlink common configuration information and is configured with semi-static SBFD configuration information, and determines any one first PO as a valid PO based on the first condition;

[0360] In some embodiments, the first condition indicates at least one of the following: the positional relationship between the first PO and the SSB; the overlapping relationship between the first PO and the effective RO in the time domain and / or frequency domain; the overlapping relationship between the first PO and the outside of the UL subband; the relationship between the first PO and the F symbol or the SBFD symbol.

[0361] For example, tdd-UL-DL-ConfigurationCommon (time division duplex uplink and downlink common configuration information) is not configured, semi-SBFD (semi-static SBFD) is configured, and the PO that meets conditions 1-1-1 to 1-1-5 is a valid PO:

[0362] Condition 1-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0363] □Condition 1-1-2: The interval between PO and the symbol where the previous SSB is located is at least Ngap symbols;

[0364] □Condition 1-1-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0365] □Condition 1-1-4: PO does not overlap with the UL subband on the SBFD symbol;

[0366] □Condition 1-1-5: PO is within the F symbol or PO is within the SBFD symbol.

[0367] In some embodiments, the terminal or network device determines that any valid PO is only allowed to overlap with one of the SBFD time unit and the non-SBFD time unit, configures time division duplex uplink and downlink common configuration information and configures semi-static SBFD configuration information, and determines that any first PO is a valid PO based on the second condition.

[0368] In some embodiments, the second condition includes: the first PO is within an uplink UL symbol, and the UL symbol is a UL symbol that remains after being configured via semi-static SBFD configuration information; the first PO has no overlap with any valid RO in the time domain and / or frequency domain.

[0369] In some embodiments, the second condition indicates at least one of the following: a relationship between the first PO and a UL symbol; an overlapping relationship between the first PO and a valid RO in the time domain and / or frequency domain.

[0370] In some embodiments, the second condition includes: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least Ngap symbols away from the symbol where the previous SSB is located, and the first PO is at least Ngap symbols away from the previous downlink DL symbol, where the DL symbol is a symbol that remains DL after being configured via semi-static SBFD configuration information, and Ngap is an integer greater than or equal to 0; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the first PO has no overlap with the UL subband on the SBFD symbol; the first PO is within the SBFD symbol or the first PO is within the non-SBFD symbol.

[0371] In some embodiments, the second condition indicates at least one of the following: a relationship between the first PO and a UL symbol; an overlapping relationship between the first PO and a valid RO in the time domain and / or frequency domain.

[0372] In some embodiments, the second condition includes: the positional relationship between the first PO and the SSB; the positional relationship between the first PO and the DL symbol; the overlapping relationship between the first PO and the effective RO in the time domain and / or frequency domain; the overlapping relationship between the first PO and the UL sub-outer band; the relationship between the first PO and the SBFD symbol or the non-SBFD symbol.

[0373] For example, if tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured, a PO that meets conditions 1-2-1 and 1-2-4 or conditions 1-2-2 to 1-2-6 is a valid PO:

[0374] Condition 1-2-1: The PO is within the UL symbol. The UL symbol refers to the symbol that remains UL after semi-SBFD configuration.

[0375] Condition 1-2-2: In a PUSCH slot, the PO does not precede the SSB.

[0376] Condition 1-2-3: The interval between the PO and the symbol containing the previous SSB is at least Ngap symbols, and the interval between the PO and the previous DL symbol is at least Ngap symbols. DL symbols refer to symbols that remain DL after semi-SBFD configuration.

[0377] □Condition 1-2-4: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0378] □Condition 1-2-5: PO does not overlap with the UL subband on the SBFD symbol;

[0379] □Condition 1-2-6: PO is within an SBFD symbol or PO is within a non-SBFD symbol.

[0380] In order to better understand the embodiments of the present disclosure, an exemplary embodiment is provided for further explanation:

[0381] Example 1

[0382] In some embodiments, a method for determining a valid PO is used when a valid PO cannot span SBFD and non-SBFD symbols.

[0383] Please refer to Figures 2b and 2c, which show a time domain and / or frequency domain resource of a PO configuration. Figure 2b shows the case where tdd-UL-DL-ConfigurationCommon is not configured, and Figure 2c shows the case where tdd-UL-DL-ConfigurationCommon is configured.

[0384] The specific description of time-frequency resource configuration is as follows:

[0385] For the time domain:

[0386] In some embodiments, msgA-PUSCH-TimeDomainOffset: is used to determine the starting time slot of PUSCH.

[0387] In some embodiments, msgA-PUSCH-TimeDomainOffset is the offset between the starting time slot of PUSCH and the PRACH slot containing the valid RO, in slots, using the SCS (Subcarrier Spacing) of the active UL BWP.

[0388] In some embodiments, each PRACH slot determines the time slot where the first PO is located.

[0389] In some embodiments, the value of msgA-PUSCH-TimeDomainOffset in the figure is 5, and the starting time slots of PO corresponding to the PRACH slot in slot#2 / 3 / 4 are 7, 8 and 9 respectively.

[0390] In some embodiments, nrofSlotsMsgA-PUSCH: the number of consecutive time slots containing one or more POs (PUSCH occasions), where the symbol positions of the POs in each time slot are the same.

[0391] In some embodiments, in the figure, nrofSlotsMsgA-PUSCH takes the value 1.

[0392] In some embodiments, nrofMsgA-PO-PerSlot: 1 time slot contains the number of POs.

[0393] In some embodiments, in the illustration, nrofMsgA-PO-PerSlot takes the value 1.

[0394] In some embodiments, guardPeriodMsgA-PUSCH: when multiple POs are included in one time slot, the POs are separated by guardPeriod symbol lengths.

[0395] In some embodiments, since one time slot contains one PO in the time domain, guardPeriodMsgA-PUSCH may not be configured.

[0396] For the frequency domain:

[0397] In some embodiments, frequencyStartMsgA-PUSCH: PO frequency domain starting position, offset relative to PRB0 of CC.

[0398] In some embodiments, in the figure, frequencyStartMsgA-PUSCH takes a value of 100.

[0408] In some embodiments, in the figure, msgA-IntraSlotFrequencyHopping is not configured, that is, intra-slot frequency hopping is not supported.

[0409] In some embodiments, when tdd-UL-DL-ConfigurationCommon is configured, it can be configured through ServingCellConfigCommonSIB or ServingCellConfigCommon.

[0410] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and a PO that meets conditions 1-1-1 to 1-1-5 is a valid PO.

[0411] Condition 1-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0412] Condition 1-1-2: The interval between PO and the symbol of the previous SSB is at least Ngap symbols;

[0416] In Figure 2b,

[0417] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 1-1-4, and is an invalid PO.

[0418] In some embodiments, PO#4, 5, 6, and 7 contain both SBFD symbols and F symbols, do not meet condition 1-1-5, and are invalid POs.

[0419] In some embodiments, PO#0, 1, 2, 8, 9, 10, 11 satisfies conditions 1-1-4 and 1-1-5. If PO#0, 1, 2, 8, 9, 10, 11 also satisfies conditions 1-1-1 to 1-1-3, then it is a valid PO.

[0420] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and a PO that satisfies conditions 1-2-1 and 1-2-4 or conditions 1-2-2 to 1-2-6 is a valid PO:

[0421] Condition 1-2-1: The PO is within a UL symbol. A UL symbol is a symbol that remains UL after semi-SBFD configuration.

[0422] Condition 1-2-2: In a PUSCH slot, the PO does not precede the SSB.

[0423] Condition 1-2-3: The interval between PO and the symbol containing the previous SSB is at least Ngap symbols, and the interval between PO and the previous DL symbol is at least Ngap symbols. DL symbols refer to symbols that are still DL after semi-SBFD configuration.

[0425] Condition 1-2-5: PO does not overlap with the UL subband on the SBFD symbol;

[0427] In Figure 2c:

[0428] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet conditions 1-2-5, and is an invalid PO.

[0429] In some embodiments, PO#4, 5, 6, and 7 contain both SBFD symbols and UL symbols, which do not meet conditions 1-2-6 and are invalid POs.

[0430] In some embodiments, PO#0, 1, 2 satisfies conditions 1-2-5 and 1-2-6. If PO#0, 1, 2 also satisfies conditions 1-2-2 to 1-2-4, then it is a valid PO.

[0431] In some embodiments, PO#8, 9, 10, and 11 satisfy conditions 1-2-1 and 1-2-4 and are valid POs.

[0432] In some embodiments, the terminal or network device determines that any valid PO is allowed to overlap with the sub-band full-duplex SBFD time unit and the non-SBFD time unit at the same time, the time division duplex uplink and downlink public configuration information is not configured and the semi-static SBFD configuration information is configured, and based on the third condition, determines that any first PO is a valid PO.

[0433] In some embodiments, the third condition includes: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least Ngap symbols away from the symbol where the previous SSB is located, where Ngap is an integer greater than or equal to 0; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the first PO has no overlap with the UL subband on the SBFD symbol.

[0435] For example, if tdd-UL-DL-ConfigurationCommon is not configured and semi-SBFD is configured, the PO that meets conditions 2-1-1 to 2-1-4 is a valid PO:

[0436] Condition 2-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0437] □Condition 2-1-2: The interval between PO and the symbol where the previous SSB is located is at least Ngap symbols;

[0438] □Condition 2-1-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0439] □Condition 2-1-4: PO does not overlap with the UL subband on the SBFD symbol.

[0440] In some embodiments, the terminal or network device determines that any valid PO is allowed to overlap with the sub-band full-duplex SBFD time unit and the non-SBFD time unit at the same time, configures time division duplex uplink and downlink common configuration information and configures semi-static SBFD configuration information, and determines that any first PO is a valid PO based on the fourth condition.

[0441] In some embodiments, the fourth condition includes: the first PO is within a UL symbol, and the UL symbol is a symbol that is still UL after being configured via semi-static SBFD; the first PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0442] Alternatively, the fourth condition includes: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least Ngap symbols away from the symbol where the previous SSB is located, and the first PO is at least Ngap symbols away from the previous DL symbol, the DL symbol is a symbol that is still DL after being configured through semi-static SBFD configuration information, and Ngap is an integer greater than or equal to 0; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the first PO has no overlap with the UL subband on the SBFD symbol.

[0443] In some embodiments, the fourth condition indicates at least one of the following: a relationship between the first PO and a UL symbol; an overlapping relationship between the first PO and a valid RO in the time domain and / or frequency domain.

[0444] In some embodiments, the fourth condition indicates at least one of the following: the positional relationship between the first PO and the SSB; the positional relationship between the first PO and the DL symbol; the overlapping relationship between the first PO and the effective RO in the time domain and / or frequency domain; the overlapping relationship between the first PO and the UL sub-outer band.

[0445] For example, if tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured, a PO that satisfies conditions 2-2-1 and 2-2-4 or conditions 2-2-2 to 2-2-5 is a valid PO:

[0446] Condition 2-2-1: The PO is within the UL symbol. The UL symbol refers to the symbol that remains UL after semi-SBFD configuration.

[0447] Condition 2-2-2: In a PUSCH slot, the PO does not precede the SSB.

[0448] Condition 2-2-3: The interval between the PO and the symbol containing the previous SSB is at least Ngap symbols, and the interval between the PO and the previous DL symbol is at least Ngap symbols. DL symbols refer to symbols that remain DL after semi-SBFD configuration.

[0453] In some embodiments, a valid PO may span SBFD and non-SBFD symbols. A method for determining a valid PO is shown in Figures 2d and 2e for configuring time and / or frequency domain resources for a PO. Figure 2d shows the case where tdd-UL-DL-ConfigurationCommon is not configured, and Figure 2e shows the case where tdd-UL-DL-ConfigurationCommon is configured. For an explanation of the configuration of time and / or frequency domain resources for PO, refer to Example 1.

[0454] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, and there is semi-SBFD configuration, and the PO that meets conditions 2-1-1 to 2-1-4 is a valid PO.

[0455] Condition 2-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0456] □Condition 2-1-2: The interval between PO and the symbol where the previous SSB is located is at least Ngap symbols;

[0457] □Condition 2-1-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0458] □Condition 2-1-4: PO does not overlap with the UL subband on the SBFD symbol.

[0459] In Figure 2d:

[0460] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 2-1-4, and is an invalid PO.

[0461] In some embodiments, PO#0,1,2,4,5,6,8,9,10,11 satisfies condition 2-1-4. If PO#0,1,2,4,5,6,8,9,10,11 also satisfies conditions 2-1-1 to 2-1-3, then it is a valid PO.

[0462] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured. A PO that satisfies conditions 2-2-1 and 2-2-4 or conditions 2-2-2 to 2-2-5 is a valid PO:

[0463] Condition 2-2-1: The PO is within the UL symbol. The UL symbol refers to the symbol that remains UL after semi-SBFD configuration.

[0464] Condition 2-2-2: In a PUSCH slot, the PO does not precede the SSB.

[0465] Condition 2-2-3: The interval between the PO and the symbol containing the previous SSB is at least Ngap symbols, and the interval between the PO and the previous DL symbol is at least Ngap symbols. DL symbols refer to symbols that remain DL after semi-SBFD configuration.

[0466] □Condition 2-2-4: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0467] □Condition 2-2-5: PO does not overlap with the UL subband on the SBFD symbol;

[0468] In Figure 2e:

[0469] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 2-2-5, and is an invalid PO.

[0470] In some embodiments, PO#0,1,2,4,5,6 satisfies condition 2-2-5. If PO#0,1,2,4,5,6 also satisfies conditions 2-2-2 to 2-2-4, then they are valid POs.

[0471] In some embodiments, PO#8, 9, 10, and 11 satisfy conditions 2-2-1 and 2-2-4 and are valid POs.

[0472] In some embodiments, the terminal or network device determines that any valid PO is only allowed to overlap with the SBFD time unit, is not configured with time division duplex uplink and downlink common configuration information, and is configured with semi-static SBFD configuration information, and determines any first PO as a valid PO based on the fifth condition.

[0473] In some embodiments, the fifth condition includes: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least Ngap symbols away from the symbol where the previous SSB is located, where Ngap is an integer greater than or equal to 0; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the first PO has no overlap with the UL subband on the SBFD symbol; the first PO is within the SBFD symbol.

[0474] In some embodiments, the fifth condition indicates at least one of the following: the positional relationship between the first PO and the SSB; the overlapping relationship between the first PO and the effective RO in the time domain and / or frequency domain; the overlapping relationship between the first PO and the UL sub-outer band; the relationship between the first PO and the SBFD symbol.

[0475] For example, if tdd-UL-DL-ConfigurationCommon is not configured and semi-SBFD is configured, the PO that meets conditions 3-1-1 to 3-1-5 is a valid PO:

[0476] □Condition 3-1-1: In a PUSCH slot, the PO does not precede the SSB;

[0477] □Condition 3-1-2: The interval between PO and the symbol where the previous SSB is located is at least Ngap symbols;

[0478] □Condition 3-1-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0479] □Condition 3-1-4: PO does not overlap with the UL subband on the SBFD symbol;

[0480] □Condition 3-1-5: PO is within the SBFD symbol.

[0481] In some embodiments, the terminal or network device determines that any valid PO is only allowed to overlap with the SBFD time unit, configures time division duplex uplink and downlink common configuration information and configures semi-static SBFD configuration information, and determines any first PO as a valid PO based on the sixth condition.

[0482] In some embodiments, the sixth condition includes: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least Ngap symbols away from the symbol where the previous SSB is located, and the first PO is at least Ngap symbols away from the previous DL symbol, the DL symbol is a symbol that is still DL after being configured through semi-static SBFD configuration information, and Ngap is an integer greater than or equal to 0; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the first PO has no overlap with the UL subband on the SBFD symbol; the first PO is within the SBFD symbol.

[0484] For example, if tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured, the PO that meets conditions 3-2-1 to 3-2-5 is a valid PO:

[0485] □Condition 3-2-1: In a PUSCH slot, PO does not precede SSB;

[0486] Condition 3-2-2: The interval between the PO and the symbol containing the previous SSB is at least Ngap symbols, and the interval between the PO and the previous DL symbol is at least Ngap symbols. DL symbols refer to symbols that are still DL after semi-SBFD configuration.

[0487] □Condition 3-2-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0488] □Condition 3-2-4: PO does not overlap with the UL subband on the SBFD symbol;

[0489] □Condition 3-2-5: PO is within the SBFD symbol.

[0490] In order to better understand the embodiments of the present disclosure, an exemplary embodiment is provided for further explanation:

[0491] Example 3

[0492] In some embodiments, valid PO can only be determined when the symbol is SBFD.

[0493] In some embodiments, a time domain and / or frequency domain resource of a PO configuration is shown in Figures 2f and 2g.

[0502] In some embodiments, PO#4, 5, 6, 7, 8, 9, 10, 11 contain non-SBFD symbols, do not meet condition 3-1-5, and are invalid POs.

[0503] In some embodiments, PO#0, 1, 2 satisfies conditions 3-1-4 and 3-1-5. If PO#0, 1, 2 also satisfies conditions 3-1-1 to 3-1-3, then they are valid POs.

[0512] In some embodiments, PO#4, 5, 6, 7, 8, 9, 10, 11 contain non-SBFD symbols, do not meet condition 3-2-5, and are invalid POs.

[0513] In some embodiments, PO#0, 1, 2 meet conditions 3-2-4 and 3-2-5. If PO#0, 1, 2, 8, 9, 10, 11 also meet conditions 3-2-1 to 3-2-3, then they are valid POs.

[0514] In some embodiments, the terminal or network device determines that any valid PO is only allowed to overlap with non-SBFD time units, is not configured with time division duplex uplink and downlink common configuration information, and is configured with semi-static SBFD configuration information, and determines that any first PO is a valid PO based on the seventh condition.

[0527] Condition 4-2-1: PO is within the UL symbol. The UL symbol refers to the symbol that remains UL after semi-SBFD configuration.
