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

[0139] To better understand the embodiments of the present disclosure, the following examples illustrate relevant scenarios:

[0140] In order to improve uplink (UL) coverage and throughput, duplex enhancement (duplex enhancement) has been studied on subband full duplex (SBFD).

[0141] 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. The 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:

[0142] TDD-UL-DL-ConfigCommon configuration;

[0143] TDD-UL-DL-ConfigDedicated configuration;

[0144] TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated configurations; and,

[0145] Downlink control information format 2-0 (DCI format 2-0) indication.

[0146] When a symbol includes both a DL subband and a UL subband in the frequency domain, it may be called an SBFD symbol.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] In some embodiments, the SSB referred to below may be the SSB selected by the UE mentioned above.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] In some embodiments, determining whether a PO is a valid PO requires considering at least one of the following factors:

[0158] Whether the legacy DL symbol is configured as SBFD;

[0159] Whether the frequency domain range of PO is within the UL subband;

[0160] Whether a valid PO can span SBFD and non-SBFD symbols;

[0161] In a PUSCH time slot, can PO precede SSB?

[0162] Whether the interval between PO and the symbol of the previous SSB can be 0;

[0163] Whether there is time domain overlap between SBFD symbols and SSB in PO.

[0164] In some embodiments, for MsgA-PUSCH time-frequency resource configuration, there are the following embodiments:

[0165] 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.

[0166] In some embodiments, msgA-PUSCH-TimeDomainOffset indicates: the starting time slot of the PUSCH;

[0167] 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;

[0168] 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;

[0169] In some embodiments, nrofMsgA-PO-PerSlot indicates: the number of POs contained in one time slot;

[0170] 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.

[0171] In some embodiments, the frequency domain configuration may be determined based on whether Interlaced PUSCH is configured.

[0172] In some embodiments, if Interlaced PUSCH is configured, the frequency domain range may be determined based on at least one of the following:

[0173] 1. interlaceIndexFirstPO-MsgA-PUSCH indicates the first interlace index;

[0174] 2. nrofInterlacesPerMsgA-PO indicates the number of interlaces;

[0175] 3. A CRB contained in an Interlace.

[0176] In some embodiments, if Interlaced PUSCH is not configured, the frequency domain range may be determined based on at least one of the following:

[0177] 1. frequencyStartMsgA-PUSCH: PO frequency domain starting position, offset relative to CC PRB0;

[0178] 2. nrofPRBs-PerMsgA-PO: number of RBs in PO;

[0179] 3. nrofMsgA-PO-FDM: the number of FDMeds of PO at the same time domain position;

[0180] 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;

[0181] 5. Hopping:

[0182] In some embodiments, hopping may include at least one of msgA-IntraSlotFrequencyHopping and msgA-HoppingBits.

[0183] In some embodiments, msgA-IntraSlotFrequencyHopping indicates: whether the PO allows intra-slot hopping;

[0184] 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.

[0185] In some embodiments, for the symbol where the PUSCH is located and the mapping type, the mapping type includes Option 1 and Option 2.

[0186] In some embodiments, Option 1 is: determining the symbol and PUSCH mapping type according to msgA-PUSCH-timeDomainAllocation;

[0187] Exemplarily, PUSCH-ConfigCommon->PUSCH-TimeDomainResourceAllocationList is configured.

[0188] As an example, one row in PUSCH-ConfigCommon->PUSCH-TimeDomainResourceAllocationList is used.

[0189] In some embodiments, Option 2 is: determined according to startSymbolAndLengthMsgA-PO and mappingTypeMsgA-PUSCH;

[0190] 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);

[0191] Exemplarily, the UE does not expect overlap in the time domain and / or frequency domain between multiple POs configured in a MsgA-PUSCH-Config.

[0192] In some embodiments, the judgment criteria for valid PO can be determined based on the configuration of tdd-UL-DL-ConfigurationCommon.

[0193] In some embodiments, if tdd-UL-DL-ConfigurationCommon is not configured, the criterion for determining a valid PO may adopt solution 1.

[0194] In some embodiments, solution 1 is: when conditions 1-1, 1-2, and 1-3 are met, the PO is a valid PO;

[0195] Condition 1-1: In a PUSCH slot, the PO does not precede the SSB.

[0196] Condition 1-2: PO is at least N symbols away from the symbol where the previous SSB is located;

[0197] Conditions 1-3: The PO does not overlap with any valid RO in the time domain and / or frequency domain.

[0198] In some embodiments, if the UE is configured with tdd-UL-DL-ConfigurationCommon, the criterion for determining a valid PO may adopt scheme 2.

[0199] 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.

[0200] Condition 2-1: PO is within the UL symbol;

[0201] Condition 2-2: In a PUSCH slot, the PO does not precede the SSB.

[0202] Condition 2-3: The PO is at least N symbols away from the symbol where the previous SSB is located, and the PO is at least N symbols away from the symbol where the previous DL is located;

[0203] Condition 2-4: PO does not overlap with any valid RO in the time domain and / or frequency domain.

[0204] In some embodiments, in the above scheme, N is an integer greater than or equal to 0, and the specific value is determined according to the existing protocol.

[0205] Please refer to Figure 1d, which shows the time domain positions of valid PO and invalid PO.

[0206] It should be noted that the Valid PO determination does not take into account at least one of the following factors:

[0207] Whether the legacy DL symbol is configured as SBFD;

[0208] The frequency domain ranges that SBFD symbols and UL symbols can use for UL transmission are different;

[0209] Whether a valid PO can span SBFD and non-SBFD symbols;

[0210] In a PUSCH time slot, can PO precede SSB?

[0212] Whether there is time domain overlap between SBFD symbols and SSB in PO.

[0213] 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:

[0214] Step S2101: The network device sends the second information and / or the third information to the terminal.

[0215] In some embodiments, the terminal receives second information sent by the network device.

[0216] In some embodiments, the terminal may be a first type terminal.

[0217] In some embodiments, the first type of terminal is a terminal capable of identifying sub-band full-duplex (SBFD) time-frequency configuration (SBFD aware UE).

[0218] In some embodiments, the second type of terminal in the present disclosure is a terminal that cannot identify the SBFD time-frequency configuration (non-SBFD aware UE).

[0219] In some embodiments, the second information is used to determine the first information.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] In some embodiments, the second 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.

[0224] 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.

[0225] 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.

[0226] 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.

[0227] In some embodiments, dynamic indications may be performed and used in real time.

[0228] In some embodiments, a static indication may require activation through an activation command before use.

[0229] 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.

[0230] In some embodiments, each time unit corresponds to a time domain and / or frequency domain position.

[0231] In some embodiments, the third information is used to indicate configuration parameters of the first PO.

[0232] In some embodiments, the configuration parameters of the first PO include the time-frequency position of the first PO within the configuration period.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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 the SBFD symbol or both the 1st hop (first hop) and the 2nd hop (second hop) are within the non-SBFD symbol.

[0237] In some embodiments, the first number of resource blocks (RBs) is the number of RBs in the UL frequency domain range on non-SBFD symbols, the second number of RBs is the number of RBs in the UL frequency domain range on SBFD symbols, the frequency hopping offset value determined according to the first number of RBs is the first offset value, and the frequency hopping offset value determined according to the second number of RBs is the second offset value. When PO performs intra-slot frequency hopping, the starting RB of the first hop of PO is the first starting RB, and the starting RB of the second hop of PO is the second starting RB.

[0238] In some embodiments, the first starting RB of the SBFD symbol is different from the first starting RB of the non-SBFD symbol.

[0239] In some embodiments, the frequency hopping offset used in intra-slot frequency hopping within a time slot is determined according to the symbol category where the PO is located, using a first offset in non-SBFD symbols and a second offset in SBFD symbols.

[0240] In some embodiments, the second starting RB in intra-slot frequency hopping is determined according to the symbol category of the PO. For example:

[0241] In non-SBFD notation:

[0242] Second starting RB = (first starting RB + first offset) mod the number of first RBs;

[0243] In SBFD notation:

[0244] Second starting RB=(first starting RB+second offset) mod the number of second RBs.

[0245] It should be noted that step S2101 may be an optional step.

[0246] Step S2102: The terminal or network device determines first information. In some embodiments, the first information is used to indicate at least one of the following:

[0247] A first PUSCH resource for random access RA of a first type of terminal and a second type of terminal;

[0248] The second PUSCH resource is used for RA of the second type of terminals and the third PUSCH resource is used for RA of the first type of terminals.

[0249] In some embodiments, one set of PUSCH resources may be configured through first information for non-SBFD aware UEs and SBFD aware UEs, which is referred to as first PUSCH resources.

[0250] In some embodiments, two sets of PUSCH resources may be configured through the first information for use with non-SBFD aware UEs and SBFD aware UEs, respectively, which are referred to as second PUSCH resources and third PUSCH resources.

[0251] In some embodiments, a SBFD aware UE may use the second PUSCH resource and the third PUSCH resource.

[0252] In some embodiments, the first type of terminal is a terminal that can recognize sub-band full-duplex (SBFD) time-frequency configuration; and the second type of terminal is a terminal that cannot recognize SBFD time-frequency configuration.

[0253] In some embodiments, the POs in the first PUSCH resource, the second PUSCH resource, and the third PUSCH resource include at least one of the following categories:

[0254] The first type of PO is a PO that contains non-SBFD symbols but does not contain SBFD symbols;

[0255] The second type of PO is a PO that includes the first type of SBFD symbol and does not include the second type of SBFD symbol;

[0256] The third type of PO is a PO containing the second type of SBFD symbol;

[0257] In some embodiments, the first type of SBFD symbols are symbols configured as flexible F symbols by TDD-UL-DL-ConfigCommon, or symbols that are not configured with TDD-UL-DL-ConfigCommon and are configured as SBFD symbols; the second type of SBFD symbols are symbols configured as downlink DL symbols by TDD-UL-DL-ConfigCommon and are configured as SBFD symbols.

[0258] In some embodiments, the PO included in the first PUSCH resource, the second PUSCH resource, and / or the third PUSCH resource includes at least one of the following PO categories:

[0259] The first type of PO: PO containing only non-SBFD symbols;

[0260] The second type of PO: PO that includes SBFD (legacy F) but does not include SBFD (legacy DL); SBFD (legacy F): TDD-UL-DL-ConfigCommon is configured as F or there is no TDD-UL-DL-ConfigCommon configuration, and the configuration is SBFD symbols; SBFD (legacy DL): TDD-UL-DL-ConfigCommon is configured as DL, and the configuration is SBFD symbols;

[0261] The third type of PO: PO including SBFD (legacy DL).

[0262] In some embodiments, the conditions for determining whether the POs in the second category PO and the third category PO are valid POs are different.

[0263] In some embodiments, in the third PUSCH resource, the first type of PO is an invalid PO.

[0264] In some embodiments, the POs in the second category of POs and / or the third category of POs where the symbols where the POs are located include at least one non-SBFD symbol are invalid POs.

[0265] In some embodiments, the conditions for determining valid POs in the second category PO and the third category PO may be different.

[0266] In some embodiments, when the second type of PO in the first PUSCH resource and the second type of PO in the third PUSCH resource use the above scheme, the conditions considered may be different.

[0267] In some embodiments, in the third PUSCH resource, a valid PO in the first type of PO, the second type of PO and / or the third type of PO can be determined based on any condition in the present disclosure.

[0268] In some embodiments, in the third PUSCH resource, the first type of PO is an invalid PO, and the valid PO in the second type of PO and / or the third type of PO can be determined based on any condition in the present disclosure.

[0269] In some embodiments, in the third PUSCH resource, the first type of PO is an invalid PO, and in the second type of PO and / or the third type of PO, the symbol where the PO is located includes at least one non-SBFD symbol is an invalid PO, and the valid PO in the PO other than the invalid PO can be determined based on any condition in the present disclosure.

[0270] In some embodiments, only the frequency domain configuration of the second type of PO and / or the third type of PO is configured in the third PUSCH resource.

[0271] In some embodiments, the UL symbols described in the present disclosure are configured as UL symbols by TDD-UL-DL-ConfigCommon and are not configured as SBFD symbols.

[0272] In some embodiments, the DL symbols described in the present disclosure are configured as DL symbols by TDD-UL-DL-ConfigCommon and are not configured as SBFD symbols.

[0273] In some embodiments, when the MsgA-PUSCH frequency domain configuration on the SBFD symbol and the non-SBFD symbol in the first PUSCH resource / the second PUSCH resource / the third PUSCH resource is the same, when Interlaced PUSCH is not configured, the starting position of the MsgA-PUSCH frequency domain frequencyStartMsgA-PUSCH-r16 is understood differently in different PO categories:

[0274] Option 1: The frequency domain starting position of MsgA-PUSCH (the frequency domain starting position of the lowest frequency PO) relative to the starting position of the UL frequency domain range on the non-SBFD symbol is offset by frequencyStartMsgA-PUSCH-r16;

[0275] Option 2: The offset value of the starting position of the MsgA-PUSCH frequency domain (the frequency domain starting position of the lowest frequency PO) relative to the starting position of the UL frequency domain range on the SBFD symbol is frequencyStartMsgA-PUSCH-r16.

[0276] In some embodiments, Option 1 is used for the first type PO, the second type PO, and the third type PO.

[0277] In some embodiments, Option 2 is used for the first type PO, the second type PO, and the third type PO.

[0278] In some embodiments, the first type of PO uses Option 1, and the second type of PO and the third type of PO use Option 2.

[0279] In some embodiments, the first and second types of POs use Option 1, and the third type of PO uses Option 2.

[0280] In some embodiments, in the first PUSCH resource / the second PUSCH resource / the third PUSCH resource, the first type PO and the second type PO use Option 1, and the third type PO uses Option 2.

[0281] In some embodiments, in the first PUSCH resource / second PUSCH resource, the first type PO and the second type PO use Option 1, and the third type PO uses Option 2; in the third PUSCH resource, the first type PO uses Option 1, and the second type PO and the third type PO use Option 2.

[0282] In some embodiments, when Interlaced PUSCH is configured in the first PUSCH resource / the second PUSCH resource, the UE does not expect the configured PO to include the second type of PO. When Interlaced PUSCH is configured in the third PUSCH resource, the frequency domain range of PO is determined differently for different PO categories:

[0283] Option 3: The frequency domain range of MsgA-PUSCH is determined based on the UL available frequency domain range on non-SBFD symbols;

[0284] Option 4: The frequency domain range of MsgA-PUSCH is determined according to the UL available frequency domain range on the SBFD symbol.

[0285] In some embodiments, Option 3 is used for the first type PO, the second type PO, and the third type PO.

[0286] In some embodiments, Option 4 is used for the first type PO, the second type PO, and the third type PO.

[0287] In some embodiments, the first type of PO uses Option 3, and the second and third types of PO use Option 4.

[0288] In some embodiments, the first and second types of POs use Option 3, and the third type of POs uses Option 4.

[0289] In some embodiments, in the first PUSCH resource / the second PUSCH resource / the third PUSCH resource, the first type of PO uses Option 3, and the third type of PO uses Option 4. In the third PUSCH resource, the second type of PO uses Option 3.

[0290] In some embodiments, in the first PUSCH resource / second PUSCH resource, the first type of PO uses Option 3, and the third type of PO uses Option 4; in the third PUSCH resource, the first type of PO uses Option 3, and the second and third types of PO use Option 4.

[0291] In some embodiments, the first information may be determined based on second information and / or third information received from the network device.

[0292] 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.

[0293] 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.

[0294] 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.

[0295] Step S2103: The terminal or the network device determines whether the first physical uplink shared channel opportunity PO is a valid PO.

[0296] In some embodiments, the valid PO satisfies at least one of the following conditions:

[0297] The valid PO is within an uplink UL symbol, and the UL symbol is configured as a UL symbol and is not configured as an SBFD symbol;

[0298] In a physical uplink shared channel PUSCH time slot, the time domain position of the valid PO is not before the time domain position of the synchronization broadcast block SSB;

[0299] The valid PO and the last symbol of the SSB symbol preceding the time domain position of the valid PO are separated by at least N symbols in the time domain, where N is an integer greater than or equal to 0;

[0300] The effective PO has no overlap with the time domain position of the SSB on the non-SBFD symbol;

[0301] The valid PO is spaced at least N symbols from the downlink DL symbol preceding the valid PO time domain position, and the DL symbol is configured as a DL symbol and is not configured as an SBFD symbol;

[0302] The frequency domain range of the effective PO on the SBFD symbol does not overlap with the first frequency range, and the first frequency range includes the DL subband and / or the guard band GB; here, the first frequency range can also be called the UL subband.

[0303] The valid PO does not contain SBFD symbols and non-SBFD symbols at the same time;

[0304] The valid PO is on the SBFD symbol;

[0305] The valid PO is on a non-SBFD symbol;

[0306] The effective PO has no overlap with any effective RO in the time domain.

[0307] In some embodiments, a valid PO must meet at least one of the following conditions:

[0308] Condition 5-0: The PO is within a UL symbol; wherein the UL symbol is configured as UL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0309] Condition 5-1: In a PUSCH slot, the PO does not precede the SSB.

[0310] Condition 5-2: There is at least N symbols between the PO and the symbol where the previous SSB is located;

[0311] Condition 5-3: PO has no time overlap with SSB in non-SBFD symbols;

[0312] Condition 5-4: The PO is separated from the previous DL symbol by at least N symbols; wherein the DL symbol is configured as DL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0313] Condition 5-5: PO does not overlap with the UL subband on the SBFD symbol;

[0314] Condition 5-6: PO does not contain both SBFD and non-SBFD symbols (i.e., a valid PO cannot span SBFD and non-SBFD symbols);

[0315] Condition 5-7: PO is on the SBFD symbol (i.e. valid PO can only be on the SBFD symbol);

[0316] Condition 5-8: PO is on a non-SBFD symbol (i.e., valid PO can only be on a non-SBFD symbol);

[0317] Condition 5-9: The PO does not overlap with any valid RO in the time-frequency domain. 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.

[0318] 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.

[0319] 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;

[0320] Among them, the first condition includes at least one of the following: in a physical uplink shared channel PUSCH time slot, the first PO is not before the synchronization signal block SSB; the first PO is at least N symbols away from the symbol where the previous SSB is located, and N is an integer greater than or equal to 0; the first PO has no overlap with any valid random access channel opportunity RO in the time domain and / or frequency domain; the frequency domain range of the valid PO on the SBFD symbol has no overlap with the first frequency range, and the first frequency range includes the DL subband and / or the guard band GB; the first PO is within the F symbol or the first PO is within the SBFD symbol; the first PO has no overlap with the time domain of the SSB on the flexible F symbol.

[0321] 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 first frequency range; the relationship between the first PO and the F symbol or the SBFD symbol; the overlapping relationship between the first PO and the SSB in the time domain.

[0322] 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 valid PO satisfies at least one of conditions 1-1-1 to 1-1-6:

[0323] Condition 1-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0324] □Condition 1-1-2: The interval between PO and the symbol containing the previous SSB is at least N symbols;

[0325] □Condition 1-1-3: PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0326] □Condition 1-1-4: PO does not overlap with the UL subband on the SBFD symbol;

[0327] □Condition 1-1-5: PO is within the F symbol or PO is within the SBFD symbol;

[0328] Condition 1-1-6: PO has no time domain overlap with SSB in non-SBFD symbols.

[0346] In order to better understand the embodiments of the present disclosure, an exemplary embodiment is provided for further explanation:

[0347] Example 1

[0348] In some embodiments, a method for determining a valid PO is used when a valid PO cannot span SBFD and non-SBFD symbols.

[0349] 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.

[0350] The specific description of time-frequency resource configuration is as follows:

[0351] For the time domain:

[0352] In some embodiments, msgA-PUSCH-TimeDomainOffset: is used to determine the starting time slot of PUSCH.

[0353] 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.

[0354] In some embodiments, each PRACH slot determines the time slot where the first PO is located.

[0355] 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.

[0356] 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.

[0357] In some embodiments, in the figure, nrofSlotsMsgA-PUSCH takes the value 1.

[0358] In some embodiments, nrofMsgA-PO-PerSlot: 1 time slot contains the number of POs.

[0359] In some embodiments, in the illustration, nrofMsgA-PO-PerSlot takes the value 1.

[0360] In some embodiments, guardPeriodMsgA-PUSCH: when multiple POs are included in one time slot, the POs are separated by guardPeriod symbol lengths.

[0361] In some embodiments, since one time slot contains one PO in the time domain, guardPeriodMsgA-PUSCH may not be configured.

[0362] For the frequency domain:

[0363] In some embodiments, frequencyStartMsgA-PUSCH: PO frequency domain starting position, offset relative to PRB0 of CC.

[0364] In some embodiments, in the figure, frequencyStartMsgA-PUSCH takes a value of 100.

[0365] In some embodiments, nrofPRBs-PerMsgA-PO: the number of RBs of PO.

[0366] In some embodiments, as shown in the figure, nrofPRBs-PerMsgA-PO takes a value of 15.

[0367] In some embodiments, nrofMsgA-PO-FDM: the number of FDMeds of PO at the same time domain position.

[0368] In some embodiments, in the illustration, nrofPRBs-PerMsgA-PO is 4.

[0369] In some embodiments, guardBandMsgA-PUSCH: frequency domain interval between adjacent POs at the same time domain position.

[0370] In some embodiments, guardBandMsgA-PUSCH is 0 in the illustration.

[0371] For hopping:

[0372] In some embodiments, msgA-IntraSlotFrequencyHopping: indicates whether intra-slot hopping is allowed.

[0373] In some embodiments, msgA-HoppingBits: can be used in conjunction with msgA-HoppingBits reference to determine the frequency offset between the 1st hop and the 2nd hop of frequency hopping, where msgA-HoppingBits indicates the hopping bits in the table.

[0374] In some embodiments, in the figure, msgA-IntraSlotFrequencyHopping is not configured, that is, intra-slot frequency hopping is not supported.

[0375] In some embodiments, when tdd-UL-DL-ConfigurationCommon is configured, it can be configured through ServingCellConfigCommonSIB or ServingCellConfigCommon.

[0376] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and valid PO satisfies at least one of conditions 1-1-1 to 1-1-6:

[0377] Condition 1-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0378] Condition 1-1-2: The interval between PO and the symbol of the previous SSB is at least N symbols;

[0379] Condition 1-1-3: PO does not overlap with any valid RO in the time-frequency domain;

[0383] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and valid PO meets conditions 1-1-1 to 1-1-5.

[0384] For example, in FIG2b ,

[0385] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 1-1-4, and is an invalid PO.

[0386] In some embodiments, PO#4, 5, 6, and 7 contain both SBFD symbols and F symbols, which do not meet condition 1-1-5 and are invalid POs.

[0387] 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.

[0388] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured:

[0397] Condition 1-2-2-5: PO does not overlap with any valid RO in the time-frequency domain;

[0398] Condition 1-2-2-6: PO does not overlap with the UL subband on the SBFD symbol;

[0399] Condition 1-2-2-7: PO is within an SBFD symbol or PO is within a non-SBFD symbol.

[0400] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and valid PO meets conditions 1-2-1-1 and 1-2-1-2.

[0401] In some embodiments, dd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and valid PO satisfies conditions 1-2-2-1 to 1-2-2-3 and conditions 1-2-2-5 to 1-2-2-7.

[0402] In Figure 2c:

[0403] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet the conditions 1-2-2-6, and is an invalid PO.

[0404] In some embodiments, PO#4, 5, 6, and 7 contain both SBFD symbols and F symbols, which do not meet the conditions 1-2-2-7 and are invalid POs.

[0405] In some embodiments, PO#0, 1, 2 satisfies conditions 1-2-2-6 and 1-2-2-7. If PO#0, 1, 2 also satisfies conditions 1-2-2-1 to 1-2-2-3 and 1-2-2-5, then it is a valid PO.

[0406] In some embodiments, PO#8, 9, 10, and 11 satisfy conditions 1-2-1-1 and 1-2-1-2 and are valid POs.

[0407] 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.

[0416] 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.

[0417] In some embodiments, the fourth condition includes at least one of the following: the first PO is within a UL symbol; the UL symbol is configured as a UL symbol by TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol; the first PO does not overlap with any valid RO in the time domain and / or frequency domain;

[0432] Example 2

[0433] 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.

[0440] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and valid PO meets conditions 2-1-1 to 2-1-4.

[0441] In Figure 2d:

[0442] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 2-1-4, and is an invalid PO.

[0443] 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.

[0444] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured:

[0445] In some embodiments, a valid PO satisfies at least one of conditions 2-2-1-1 and 2-2-1-2:

[0446] Condition 2-2-1-1: The PO is within a UL symbol, and the UL symbol is configured as UL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0447] Condition 2-2-1-2: PO does not overlap with any valid RO in the time and frequency domain.

[0459] In some embodiments, PO#8, 9, 10, and 11 satisfy conditions 2-2-1-1 and 2-2-1-2 and are valid POs.

[0461] In some embodiments, the fifth condition includes at least one of the following: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least N symbols away from the symbol where the previous SSB is located, where N 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 frequency domain range of the valid PO on the SBFD symbol has no overlap with the first frequency range, and the first frequency range includes the DL subband and / or the guard band GB; the first PO is within the SBFD symbol.

[0469] 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.

[0470] In some embodiments, the sixth condition includes at least one of the following: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least N symbols away from the symbol where the previous SSB is located, where N is an integer greater than or equal to 0; the DL symbol is configured as a DL symbol by TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol; the first PO has no overlap with any valid RO in the time domain and / or frequency domain; the frequency domain range of the valid PO on the SBFD symbol has no overlap with the first frequency range, and the first frequency range includes the DL subband and / or the guard band GB; the first PO is within the SBFD symbol.

[0472] For example, if tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured, the PO that meets conditions 3-2-1 to 3-2-6 is a valid PO:

[0473] □Condition 3-2-1: In a PUSCH slot, PO does not precede SSB;

[0474] □Condition 3-2-2: The interval between PO and the symbol of the previous SSB is at least N symbols;

[0475] Condition 3-2-3: The PO is separated from the previous DL symbol by at least N symbols, and the DL symbol is configured as DL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0501] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and conditions 3-2-1 to 3-2-6 are satisfied.

[0502] In Figure 2g:

[0503] In some embodiments, PO#3,7 overlaps with the UL subband, does not meet condition 3-2-5, and is an invalid PO.

[0504] In some embodiments, PO#4, 5, 6, 7, 8, 9, 10, 11 contain non-SBFD symbols, do not meet condition 3-2-6, and are invalid POs.

[0505] In some embodiments, PO#0, 1, 2 meet conditions 3-2-5 and 3-2-6. If PO#0, 1, 2, 8, 9, 10, 11 also meet conditions 3-2-1 to 3-2-4, then they are valid POs.

[0506] 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.

[0507] In some embodiments, the seventh condition includes at least one of the following: in a PUSCH time slot, the first PO is not before the SSB; the first PO is at least N symbols away from the symbol where the previous SSB is located, where N 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 is within a non-SBFD symbol; the first PO has no overlap with the time domain of the SSB on the non-SBFD symbol.

[0515] In some embodiments, the terminal or network device determines that any valid PO is only allowed to overlap with non-SBFD time units, 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 eighth condition.

[0520] For example, tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured:

[0521] In some embodiments, a valid PO satisfies at least one of conditions 4-2-1-1 and 4-2-1-2:

[0522] Condition 4-2-1-1: The PO is within a UL symbol, and the UL symbol is configured as UL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0523] Condition 4-2-1-2: PO does not overlap with any valid RO in the time-frequency domain.

[0531] In order to better understand the embodiments of the present disclosure, an exemplary embodiment is provided for further explanation:

[0532] Example 4

[0533] In some embodiments, valid PO can only be determined when the symbol is not SBFD.

[0534] In some embodiments, a time domain and / or frequency domain resource of a PO configuration is shown in Figures 2h and 2i. Figure 2h shows the case where tdd-UL-DL-ConfigurationCommon is not configured, and Figure 2i shows the case where tdd-UL-DL-ConfigurationCommon is configured. For the description of the time domain and / or frequency domain resource configuration of PO, please refer to Example 1.

[0535] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and valid PO satisfies at least one of conditions 4-1-1 to 4-1-5:

[0536] Condition 4-1-1: In a PUSCH slot, the PO does not precede the SSB.

[0537] Condition 4-1-2: The interval between PO and the symbol of the previous SSB is at least N symbols;

[0538] Condition 4-1-3: PO does not overlap with any valid RO in the time-frequency domain;

[0539] Condition 4-1-4: PO is in a non-SBFD symbol;

[0540] Condition 4-1-5: PO has no time domain overlap with SSB in non-SBFD symbols.

[0541] In some embodiments, tdd-UL-DL-ConfigurationCommon is not configured, semi-SBFD is configured, and valid PO satisfies conditions 4-1-1 to 4-1-4.

[0542] In Figure 2h:

[0543] In some embodiments, PO#0-7 contain SBFD symbols, do not meet condition 4-1-4, and are invalid POs.

[0544] In some embodiments, PO#8, 9, 10, 11 satisfies condition 4-1-4. If PO#8, 9, 10, 11 also satisfies conditions 4-1-1 to 4-1-3, then they are valid POs.

[0545] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured and semi-SBFD is configured:

[0546] In some embodiments, a valid PO satisfies at least one of conditions 4-2-1-1 and 4-2-1-2:

[0547] Condition 4-2-1-1: The PO is within a UL symbol, and the UL symbol is configured as UL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0548] Condition 4-2-1-2: PO does not overlap with any valid RO in the time-frequency domain.

[0549] In some embodiments, a valid PO satisfies at least one of conditions 4-2-2-1 and 4-2-2-6:

[0550] Condition 4-2-2-1: In a PUSCH slot, PO does not precede SSB;

[0551] Condition 4-2-2-2: The interval between PO and the symbol of the previous SSB is at least N symbols;

[0552] Condition 4-2-2-3: The PO is at least N symbols away from the previous DL symbol, and the DL symbol is configured as DL in TDD-UL-DL-ConfigCommon and is not configured as an SBFD symbol;

[0553] Condition 4-2-2-4: PO has no time overlap with SSB in non-SBFD symbols;

[0554] Condition 4-2-2-5: PO does not overlap with any valid RO in the time-frequency domain;

[0555] Condition 4-2-2-6: PO is within a non-SBFD symbol.

[0556] In some embodiments, tdd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and valid PO satisfies conditions 4-2-1-1 and 4-2-1-2; in some embodiments, tdd-UL-DL-ConfigurationCommon is configured, semi-SBFD is configured, and valid PO satisfies conditions 4-2-2-1 to 4-2-2-3 and conditions 4-2-2-5 to 4-2-2-6.

[0557] In Figure 2i:

[0558] In some embodiments, PO#0-7 contain SBFD symbols, do not meet condition 4-2-2-6, and are invalid POs.

[0559] In some embodiments, PO#8, 9, 10, 11 meet conditions 4-2-1-1 and 4-2-2-6. If PO#8, 9, 10, 11 also meet condition 4-2-2-5, then they are valid POs.

[0560] In some embodiments, a non-SBFD aware UE uses Option 1-1 and Option 1-2 to determine whether the PO is valid.

[0561] In some embodiments, when Option 1-1: tdd-UL-DL-ConfigurationCommon is not configured, a valid PO satisfies at least one of conditions 1-1 and 1-2 of the following conditions:

[0562] Condition 1-1: In the first time slot, PO does not precede SSB;

[0563] Condition 1-2: PO is at least N symbols away from the symbol where the previous SSB is located;

[0564] Condition 1-3: PO does not overlap with any valid RO in the time-frequency domain.

[0565] In some embodiments, when Option 1-2: tdd-UL-DL-ConfigurationCommon is configured, a valid PO satisfies condition 2-1 of the following conditions or satisfies at least one of conditions 2-2, 2-3, and 2-4 of the following conditions:

[0566] Condition 2-1: PO is within the UL symbol;

[0567] Condition 2-2: In the first time slot, PO does not precede SSB;

[0568] Condition 2-3: There is at least N symbols between PO and the symbol where the previous SSB is located;

[0569] Condition 2-4: The interval between the PO and the previous DL symbol is at least N symbols;

[0570] Condition 2-5: PO does not overlap with any valid RO in the time-frequency domain.

[0571] In some embodiments, in the first PUSCH resource and / or the second PUSCH resource, the results of the SBFD aware UE and the non-SBFD aware UE enabling by network configuration to determine whether the first type of PO and / or the second type of PO is a valid PO are the same.

[0572] For example, the UE does not expect a PO to be a valid PO for a non-SBFD aware UE and an invalid PO for a SBFD-aware UE (when both non-SBFD aware UE and SBFD-aware UE exist, avoid making the mapping relationship between RO and valid PO too complicated). For example, the UE does not expect case 1 and case 2 to occur, where:

[0573] Case 1: The F symbol is configured as SBFD through semi-SBFD. The frequency domain range of some POs on this SBFD symbol overlaps with the UL frequency domain range.

[0574] Case 2: When a valid PO cannot span SBFD and non-SBFD symbols, the F symbol is configured as SBFD through semi-SBFD, and some POs span SBFD and non-SBFD symbols, and the non-SBFD symbols are F or UL symbols.
