[0154] In some embodiments, the access network device 102-1 is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

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

[0162] In an embodiment of the present disclosure, 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 an uplink subband (UL subband) and at least one (one or two) downlink subbands. The network device can send DL signals in the downlink subband and receive UL signals in the uplink subband at the same time. Among them, the DL symbol or F symbol can be indicated as a DL symbol or F symbol by any one of the time division multiplexing uplink and downlink common configuration (TDD-UL-DL-ConfigCommon), time division multiplexing uplink and downlink dedicated configuration (TDD-UL-DL-ConfigDedicated), and the slot format indicator (SFI) of the downlink control information (DCI) format 2-0. In the embodiment of the present disclosure, the symbol refers to an orthogonal frequency division multiplexing (OFDM) symbol, which is hereinafter referred to as a symbol.

[0163] When a symbol includes both a downlink subband and an uplink subband in the frequency domain, the symbol can be called an SBFD symbol. Similarly, when a time slot includes at least one SBFD symbol, the time slot can be called an SBFD time slot.

[0164] In addition, if the symbol is not an SBFD symbol, the symbol is a non-SBFD symbol. When a time slot does not include any SBFD symbol, the time slot can be called a non-SBFD time slot.

[0165] For example, as shown in FIG1B , time slot #0 is a downlink time slot including 14 DL symbols, time slot #1 to time slot #3 are SBFD time slots, each including 14 SBFD symbols, and time slot #4 is a UL time slot including 14 UL symbols.

[0166] A DL symbol, UL symbol, or F symbol can be configured as an SBFD symbol through semistatic signaling, referred to as a semistatic SBFD (semi-SBFD) symbol. Furthermore, a DL symbol, UL symbol, or F symbol can be indicated as an SBFD symbol through dynamic signaling, referred to as a slot format indicator SBFD (SFI-SBFD) symbol. Furthermore, an SBFD symbol can be dynamically adjusted to a DL symbol, UL symbol, or F symbol through dynamic signaling.

[0167] In addition, a guard band (GB) may exist between the DL sub-band and the UL sub-band to reduce interference between the DL signal in the downlink sub-band and the UL signal in the uplink sub-band through frequency domain isolation.

[0168] In SBFD symbols, the frequency domain range available for UL transmission may include the following two cases:

[0169] Case 1: GB and downlink subbands cannot be used for UL transmission, and uplink subbands can be used for UL transmission;

[0170] Case 2: The downlink subband cannot be used for UL transmission, and the uplink subband and GB can be used for UL transmission.

[0171] In the SBFD symbol, the frequency domain range that can be used for UL transmission may be referred to as a UL transmission frequency domain range, and the frequency domain range that cannot be used for UL transmission may be referred to as outside the UL transmission frequency domain range.

[0172] Based on the above analysis, the UL transmission frequency domain ranges for non-SBFD symbols and SBFD symbols are different. For non-SBFD symbols, the UL transmission frequency domain range is the UL transmission frequency domain range on the CC. For SBFD symbols, the UL transmission frequency domain range on the uplink bandwidth part (BWP) refers to the frequency domain range where the uplink BWP overlaps with the UL transmission frequency domain range on the CC.

[0173] In SBFD symbols, the frequency domain range available for DL ​​transmission may include the following two cases:

[0174] Case 1: GB and downlink subbands can be used for DL ​​transmission, and uplink subbands cannot be used for DL ​​transmission;

[0175] Case 2: The downlink subband can be used for DL ​​transmission, and the uplink subband and GB cannot be used for DL ​​transmission.

[0176] In the 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.

[0177] Based on the above analysis, the DL transmission frequency domain ranges for non-SBFD symbols and SBFD symbols are different. For non-SBFD symbols, the DL transmission frequency domain range is the DL transmission frequency domain range on the CC. For SBFD symbols, the DL transmission frequency domain range on the downlink BWP is the frequency domain range where the downlink BWP overlaps with the DL transmission frequency domain range on the CC.

[0178] In the embodiments of the present disclosure, the subsequent DL transmission frequency domain range refers to the DL transmission frequency domain range on the DL BWP, and the UL transmission frequency domain range refers to the UL transmission frequency domain range on the UL BWP. In addition, considering the different interference conditions on non-SBFD symbols and SBFD symbols, and the possible switching time between non-SBFD symbols and SBFD symbols, a single signal transmission can be divided into the following cases:

[0179] Case 1: A DL transmission or UL transmission can only be in SBFD or non-SBFD symbols;

[0180] Case 2: A DL transmission or UL transmission can be in SBFD and non-SBFD symbols;

[0181] Case 3: A DL transmission or UL transmission can only be in SBFD symbols;

[0182] Case 4: A DL transmission or UL transmission can only be performed in non-SBFD symbols

[0183] In the embodiment of the present disclosure, if tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not configured, the symbol may be determined to be a flexible symbol. Alternatively, the first symbol set in the first time slot may be configured as a flexible symbol by the following method:

[0184] Method 1: Configure tdd-UL-DL-ConfigurationCommon as a flexible symbol.

[0185] Method 2: tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are configured as flexible symbols.

[0186] In the embodiments of the present disclosure, the meanings of the abbreviations involved below are as follows:

[0187] Dynamic-D / Dynamic-U: DCI indicates DL signal transmission / UL signal transmission;

[0188] RRC-D / RRC-U: RRC configures DL signal transmission / UL signal transmission;

[0189] any-D / any-U: includes Dynamic-D / Dynamic-U and RRC-D / RRC-U;

[0190] Semi-D / Semi-U: Semi-statically configured as DL symbols / UL symbols, including the following two methods:

[0191] Method 1: Configured as DL symbol or UL symbol by tdd-UL-DL-ConfigurationCommon;

[0192] Method 2: Configured as DL symbol or UL symbol by tdd-UL-DL-ConfigurationCommon; or

[0193] Configured by tdd-UL-DL-ConfigurationDedicated as DL symbol or UL symbol;

[0194] Semi-F: Semi-static configuration uses the F symbol or no semi-static configuration. The following three methods are available:

[0195] Method 1: Configure the tdd-UL-DL-ConfigurationCommon field as F.

[0196] Mode 2: Configure the F symbol by tdd-UL-DL-ConfigurationCommon; or configure the F symbol by tdd-UL-DL-ConfigurationDedicated;

[0197] Mode 3: No tdd-UL-DL-ConfigurationCommon configuration; and no tdd-UL-DL-ConfigurationDedicated configuration.

[0198] SFI-D / SFI-U / SFI-F: DCI format 2-0 indicates DL symbol / UL symbol / F symbol.

[0199] In an example, for a case where the network device indicates a DL signal and indicates SFI-D / SFI-F / SFI-U via DCI format 2-0, the processing rules are shown in Table 1. The network device configures dynamic signaling DCI 2-0 to indicate the symbol type, and the terminal successfully receives DCI format 2-0.

[0222] If DL#2 is Any-D (PRS), according to case 3-1-2 in Table 2, reception of DL#2 is canceled in OS#9.

[0223] In an example, for a situation where the network device indicates a UL signal and indicates Semi-F / Semi-D in a semi-static manner, the processing rules are shown in Table 3.

[0224] Table 3

[0225] In one example, as shown in FIG1E , in time slot #3, OS#0-OS#1 are Semi-D, OS#2-OS#13 are Semi-F, and the second symbol set includes OS#2-OS#13 of time slot #2 and OS#0-OS#3 of time slot #3.

[0226] Among them, UL#1 is located at OS#2-OS#11 in the time domain.

[0227] If UL#1 is Dynamic-U (PUCCH / PUSCH / PRACH / SRS), send UL#1;

[0228] The terminal is configured with enableConfiguredUL, UL#1 is RRC-U (PUCCH / PUSCH / PRACH / SRS), and UL#1 is transmitted. enableConfiguredUL is a configuration that allows the terminal to use flexible symbols for uplink transmission.

[0229] The terminal is not configured with enableConfiguredUL, and the second symbol set overlaps with the first symbol set, OS#2-OS#3:

[0230] UL#1 is RRC-U(PUCCH / PUSCH / PRACH):

[0231] The terminal does not support the partialCancellation capability and sends UL#1;

[0232] The terminal supports the partialCancellation capability. The terminal does not expect to cancel sending UL#1 between OS#2 and OS#3. The terminal cancels sending UL#1 between OS#4 and OS#11.

[0233] UL#1 is RRC-U (SRS):

[0234] The terminal does not expect to cancel the transmission of UL#1 in OS#2-OS#3, and the terminal cancels the transmission of UL#1 in OS#4-11.

[0235] Among them, UL#2 is located in OS#4-OS#13 in the time domain.

[0237] The terminal is configured with enableConfiguredUL, UL#2 is RRC-U (PUCCH / PUSCH / PRACH / SRS), and UL#2 is sent.

[0238] The terminal is not configured with enableConfiguredUL, and the second symbol set does not overlap with the first symbol set. OS:

[0239] UL#2 is RRC-U(PUCCH / PUSCH / PRACH):

[0240] The terminal does not support the partialCancellation capability and cancels sending UL#2;

[0241] The terminal supports the partialCancellation capability and cancels sending UL#2;

[0243] Among them, UL#3 is located in OS#0-OS#7 in the time domain.

[0244] According to case 4-1 in Table 3, the transmission of UL#3 is canceled.

[0245] Currently, the processing of UL signals does not take into account the different UL transmission frequency domain ranges between SBFD symbols and non-SBFD symbols, and does not consider the symbol types that can be used in one UL transmission.

[0246] When introducing SFI-SBFD, the different UL transmission frequency domain ranges / DL transmission frequency domain ranges for SBFD symbols and non-SBFD symbols, as well as the impact of the symbol types that can be used for a single UL / DL transmission on UL signal / DL signal processing criteria, are considered. Therefore, the present disclosure provides the following communication method, apparatus, and storage medium, which can determine the frequency domain range used by an uplink signal based on the symbol type of a first symbol used by a first signal. This improves uplink coverage and throughput when introducing SBFD symbols, thereby enhancing the usability and flexibility of SBFD.

[0247] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0248] Step S2101: The network device 102 sends first information.

[0249] In some embodiments, the first information is used to determine a symbol type of the symbol.

[0250] In some embodiments, the first information may be dynamic signaling, such as DCI.

[0251] In one example, the first information may configure or indicate a symbol type of the symbol through SFI.

[0252] In one example, the symbol type may include, but is not limited to, any of the following: SBFD symbol, DL symbol, UL symbol, or F symbol. Accordingly, the symbol type of the symbol indicated by dynamic signaling may be written as SFI-SBFD symbol, SFI-D symbol, SFI-U symbol, or SFI-F symbol.

[0253] In some embodiments, the first information may be high-layer signaling, including but not limited to Radio Resource Control (RRC) signaling; system messages. The system messages may include but not limited to System Information Block n (SIBn), where n may be a positive integer.

[0254] In one example, the symbol type of the symbol configured through higher layer signaling can be written as SBFD symbol / DL symbol / UL symbol / F symbol, or can be written as Semi-SBFD symbol / Semi-D symbol / Semi-U symbol / Semi-F symbol.

[0255] In some embodiments, terminal 101 receives the first information.

[0256] In some embodiments, the name of the first information is not limited. The first information may also be replaced by DCI, RRC signaling, SIBn, symbol type indication information, symbol type configuration information, etc.

[0257] Step S2102: Terminal 101 determines the symbol type of the symbol based on the first information.

[0258] In some embodiments, the first information configures or indicates the symbol type of the symbol, and the terminal can determine the symbol type of the symbol based on the first information.

[0259] The symbol type of the symbol can be SBFD or non-SBFD.

[0260] When a symbol contains both downlink and uplink subbands in the frequency domain, it is called an SBFD symbol. If it does not belong to an SBFD symbol, it is a non-SBFD symbol.

[0261] Non-SBFD symbols include any one of UL symbols, DL symbols, and F symbols.

[0262] Step S2103: the network device 102 sends the second information.

[0263] In some embodiments, the second information is used to determine the time domain resources and / or frequency domain resources used by the first signal.

[0264] The first signal may be an uplink signal, or the first signal may be a downlink signal.

[0265] Among them, the uplink signal includes but is not limited to at least one of the following: Physical Uplink Shared Channel (PUSCH); Physical Uplink Control Channel (PUCCH); Physical Random Access Channel (PRACH); Sounding Reference Signal (SRS).

[0266] The downlink signal includes, but is not limited to, at least one of the following: Physical Downlink Shared Channel (PDSCH); Physical Downlink Control Channel (PDCCH); Channel State Information-Reference Signal (CSI-RS); and DL Positioning Reference Signal (PRS). The DL PRS is abbreviated as PRS.

[0267] In some embodiments, the second information may include but is not limited to high-layer signaling, wherein the high-layer signaling may include but is not limited to RRC signaling; system messages. The system messages may include but are not limited to SIBn, where n may be a positive integer.

[0268] In some embodiments, the second information may include but is not limited to dynamic signaling, such as DCI.

[0269] In some embodiments, the second information may include high-layer signaling and dynamic signaling.

[0270] In some embodiments, the terminal 101 receives the second information,

[0271] In some embodiments, the second information may be used to indicate a symbol type that can be used for one transmission.

[0272] Illustratively, the second information may indicate any of the following:

[0273] The symbol types that can be used for one transmission include SBFD symbols or non-SBFD symbols;

[0274] The symbol types that can be used in one transmission include SBFD symbols and non-SBFD symbols;

[0275] The symbol types that can be used for one transmission include only SBFD symbols;

[0276] The symbol types that can be used for one transmission include only non-SBFD symbols.

[0277] It should also be noted that the network device 102 may indicate the symbol type that can be used for an uplink transmission through other information, such as third information. The third information may be a DCI different from the second information, which is not limited in this disclosure.

[0278] In some embodiments, terminal 101 receives second information.

[0279] In some embodiments, the name of the second information is not limited. The second information may also be replaced by DCI, RRC signaling, system message, resource indication information, resource configuration information, etc.

[0280] In step S2104 , the terminal 101 determines at least one of a time domain resource and a frequency domain resource used by the first signal based on the second information.

[0281] In some embodiments, the terminal 101 may determine the time domain resource used by the first signal based on the second information. Exemplarily, the terminal 101 determines a first symbol based on the second information, where the first symbol is a symbol used by the first signal.

[0282] In some embodiments, the terminal 101 may determine the frequency domain resources used by the first signal based on the second information, wherein the frequency domain range used by the first signal is related to the symbol type of the first symbol used by the first signal.

[0283] Terminal 101 has determined the symbol type of the symbol based on step S2102. Accordingly, after determining the first symbol used by the first signal based on the second information, terminal 101 can determine the symbol type of the first symbol. The first symbol can be an SBFD symbol or a non-SBFD symbol. When the first symbol is a non-SBFD symbol, the first symbol can be a UL symbol, a DL symbol, or an F symbol.

[0284] In an example, the terminal 101 may determine the frequency domain range used by the first signal by using any one of the following first to fourth determination methods:

[0285] The first determination method includes at least one of the following:

[0286] If the first symbol is a non-SBFD symbol, the frequency domain range used by the first signal is the second frequency domain range;

[0287] If the first symbol is an SBFD symbol, the frequency domain range used by the first signal is the third frequency domain range.

[0288] The second determination method includes at least one of the following:

[0289] If the first symbol is a non-SBFD symbol, the frequency domain range used by the first signal is the second frequency domain range;

[0290] If the first symbol is an SBFD symbol, the frequency domain range used by the first signal is the fourth frequency domain range.

[0291] The third determination method includes at least one of the following:

[0292] The first symbol is an SBFD symbol or a non-SBFD symbol, and the frequency domain range used by the first signal is the third frequency domain range or the fourth frequency domain range.

[0293] The fourth determination method includes at least one of the following:

[0294] The first symbol is an SBFD symbol or a non-SBFD symbol, and the frequency domain range used by the first signal is the second frequency domain range.

[0295] The second frequency domain range refers to the frequency domain range used by the first signal configured by the second information on non-SBFD symbols, such as the frequency domain range used by the first signal configured by RRC signaling on non-SBFD symbols. Alternatively, the second frequency domain range refers to the frequency domain range used by the first signal indicated by the second information, such as the frequency domain range used by the first signal indicated by DCI.

[0296] The third frequency domain range is a frequency domain range that overlaps the second frequency domain range and the first direction frequency domain range used by the first BWP, wherein the first direction is the same as the transmission direction of the first signal.

[0297] The fourth frequency domain range is the frequency domain range used by the first signal configured by the second information on the SBFD symbol, for example, the frequency domain range used by the first signal configured by RRC signaling on the SBFD symbol.

[0298] Furthermore, the terminal 101 may determine, based on the frequency domain range used by the uplink signal, whether the frequency domain range used by the first signal in the SBFD symbol in the first symbol overlaps with the first frequency domain range. The first frequency domain range is a frequency domain range outside the first direction frequency domain range used by the first BWP, and the first direction is the same as the transmission direction of the first signal.

[0299] Exemplarily, when the terminal 101 determines the frequency domain range used by the first signal based on any one of the above-mentioned first determination method, second determination method, and third determination method, it can be determined that the frequency domain range used by the first signal on the SBFD symbol in the first symbol does not overlap with the first frequency domain range.

[0300] Exemplarily, when the terminal 101 determines the frequency domain range used by the first signal based on the fourth determination method, it can be determined that the frequency domain range used by the first signal on the SBFD symbol in the first symbol does not overlap with the first frequency domain range.

[0301] Exemplarily, when the terminal 101 determines the frequency domain range used by the first signal based on the fourth determination method, it can be determined that the frequency domain range used by the first signal on the SBFD symbol in the first symbol overlaps with the first frequency domain range.

[0302] In one example, the first signal is a downlink signal, and the terminal 101 can determine the frequency domain range used by the downlink signal based on any one of the first determination method, the second determination method, and the third determination method. Further, the terminal 101 can determine that, on the SFI-SBFD symbol in the first symbol where the downlink signal is located, the frequency domain range used by the downlink signal does not overlap with the first frequency domain range, wherein the first frequency domain range is a frequency domain range outside the downlink frequency domain range used by the downlink BWP.

[0303] Alternatively, the first signal is a downlink signal, and the terminal 101 can determine the frequency domain range used by the downlink signal based on the fourth determination method. Furthermore, on the SFI-SBFD symbol in the first symbol where the downlink signal is located, the terminal 101 determines that the frequency domain range used by the downlink signal does not overlap with the first frequency domain range. Alternatively, on the SFI-SBFD symbol in the first symbol where the downlink signal is located, the frequency domain range of the downlink signal overlaps with the first frequency domain range, wherein the first frequency domain range is a frequency domain range outside the downlink frequency domain range used by the downlink BWP.

[0304] In one example, the first signal is an uplink signal, and the terminal 101 can determine the frequency domain range used by the uplink signal based on any one of the first determination method, the second determination method, and the third determination method. Furthermore, on the SFI-SBFD symbol in the first symbol where the uplink signal is located, the frequency domain range used by the uplink signal does not overlap with the first frequency domain range, wherein the first frequency domain range is a frequency domain range outside the uplink frequency domain range used by the uplink BWP.

[0305] Alternatively, the first signal is an uplink signal, and terminal 101 may determine the frequency domain range used by the uplink signal based on the fourth determination method. Further, on the SFI-SBFD symbol in the first symbol where the uplink signal is located, terminal 101 determines whether the frequency domain range used by the uplink signal overlaps with or does not overlap with the first frequency domain range.

[0306] In an example, if the second information is high-layer signaling, the terminal 101 may determine the frequency domain range used by the first signal based on any one of the first determination method, the second determination method, the third determination method, and the fourth determination method.

[0307] In an example, if the second information is DCI, the terminal 101 may determine the frequency domain range used by the first signal based on the first determination method.

[0308] Exemplarily, the second information is high-layer signaling and the first signal is a downlink signal. The terminal can determine the frequency domain range used by RRC-D (PDCCH, PDSCH, CSI-RS, DL PRS) based on any one of the above-mentioned first determination method, second determination method, third determination method, and fourth determination method.

[0309] Exemplarily, the second information is dynamic signaling, the first signal is a downlink signal, and the terminal may determine the frequency domain range used by Dynamic-D (PDSCH, CSI-RS) based on the first determination method.

[0310] Exemplarily, the second information is high-layer signaling and the first signal is an uplink signal. The terminal can determine the frequency domain range used by RRC-U (PUCCH, PUSCH, PRACH, SRS) based on any one of the above-mentioned first determination method, second determination method, third determination method, and fourth determination method.

[0311] Exemplarily, the second information is dynamic signaling, the first signal is an uplink signal, and the terminal can determine the frequency domain range used by Dynamic-U (PUCCH, PUSCH, PRACH, SRS) based on the first determination method.

[0312] The above is merely an exemplary description. The schemes in which the terminal 101 determines the frequency domain range used by the first signal based on different frequency domain range determination methods, and then determines whether the frequency domain range used by the first signal on the SBFD symbol overlaps with the first frequency domain range, should all fall within the protection scope of the present disclosure.

[0313] In step S2105 , the terminal 101 determines whether to send or receive a first signal.

[0314] In some embodiments, the terminal 101 may determine whether to send or receive the first signal based on a protocol agreement.

[0315] In some embodiments, the terminal 101 may determine whether to send or receive the first signal based on an instruction from the network device 102 .

[0316] In some embodiments, the terminal 101 may determine whether to send or receive the first signal based on a processing rule corresponding to the first signal.

[0317] It is understandable that the terminal 101 may also determine whether to send or receive the first uplink signal based on a protocol predefined method. The present disclosure does not limit the criteria, method, or rule for the terminal 101 to determine whether to send or receive the first signal.

[0318] In the following embodiments, terminal 101 determines whether to send or receive the first signal based on the processing rule corresponding to the first signal. In some embodiments, the first signal is a downlink signal, and terminal 101 can determine whether to receive the downlink signal based on the processing rule corresponding to the downlink signal.

[0319] In some embodiments, the first signal is an uplink signal, and the terminal 101 may determine whether to send the uplink signal based on a processing rule corresponding to the uplink signal.

[0320] In some embodiments, the processing rule is used to indicate at least one of the following:

[0321] a first correspondence between a symbol type of the first symbol and whether to send or receive the first signal;

[0322] a second correspondence between a symbol type that can be used for one transmission and whether the first signal is sent or received;

[0323] A third correspondence between whether the terminal has a partial cancellation capability and whether the first signal is sent or received.

[0324] In an embodiment of the present disclosure, the SBFD symbols that can be used for DL ​​transmission include SFI-SBFD symbols that can be used for DL ​​transmission and Semi-SBFD symbols that can be used for DL ​​transmission. The SBFD symbols that can be used for DL ​​transmission may refer to SBFD symbols whose frequency domain range of the DL signal does not overlap with the first frequency domain range, wherein the first frequency domain range refers to a frequency domain range outside the downlink transmission frequency domain range used by the downlink BWP.

[0325] SBFD symbols that cannot be used for DL ​​transmission include SFI-SBFD symbols that cannot be used for DL ​​transmission and Semi-SBFD symbols that cannot be used for DL ​​transmission. The SBFD symbols that cannot be used for DL ​​transmission may refer to SBFD symbols whose frequency domain range of the DL signal overlaps with the first frequency domain range, wherein the first frequency domain range refers to a frequency domain range outside the downlink transmission frequency domain range used by the downlink BWP.

[0326] The SBFD symbols that can be used for UL transmission include SFI-SBFD symbols that can be used for UL transmission and Semi-SBFD symbols that can be used for UL transmission. The SBFD symbols that can be used for UL transmission may refer to SBFD symbols whose frequency domain range of the UL signal does not overlap with the first frequency domain range, wherein the first frequency domain range refers to a frequency domain range outside the uplink transmission frequency domain range used by the uplink BWP.

[0327] SBFD symbols that cannot be used for UL transmission include SFI-SBFD symbols that cannot be used for UL transmission and Semi-SBFD symbols that cannot be used for UL transmission. The SBFD symbols that cannot be used for UL transmission may refer to SBFD symbols whose frequency domain range of the UL signal overlaps with the first frequency domain range, wherein the first frequency domain range refers to a frequency domain range outside the uplink transmission frequency domain range used by the uplink BWP.

[0328] The following describes the corresponding processing rules and terminal behaviors for different situations where the first signal is a downlink signal or an uplink signal, respectively. These are described in Plans A, B, and C below. In Plans A and B, the first signal is a downlink signal; in Plan C, the first signal is an uplink signal.

[0329] Solution A: The first signal is a downlink signal, and the first information is dynamic signaling, such as DCI. In this case, the symbol type is any one of SFI-SBFD / SFI-D / SFI-U / SFI-F.

[0330] If a frequency domain range used by the downlink signal on each first symbol does not overlap with the first frequency domain range, the first frequency domain range is a frequency domain range outside the first direction frequency domain range used by the first BWP, the first BWP is a downlink BWP, and the first direction is a downlink direction, that is, if an SFI-SBFD symbol exists in the first symbol, then the SFI-SBFD symbol is an SBFD symbol that can be used for DL ​​transmission. Accordingly, when the processing rule is used to indicate the above-mentioned first normalization relationship, it may include but is not limited to at least one of the following:

[0331] The first processing rule includes: receiving the downlink signal when each first symbol in which the downlink signal is located is an SBFD symbol that can be used for downlink transmission;

[0332] The second processing rule includes: receiving the downlink signal when each first symbol in which the downlink signal is located is any one of a downlink symbol and an SBFD symbol that can be used for downlink transmission;

[0333] A third processing rule includes: receiving a downlink signal when each first symbol in which the downlink signal is located is any one of an SBFD symbol, a downlink symbol, and a flexible symbol that can be used for downlink transmission;

[0395] Among them, DL#2 is received, and reception of DL#1 and DL#3 is canceled.

[0396] When a transmission is only possible in non-SBFD symbols:

[0397] DL#1 / DL#2 / DL#3 are RRC-D (downlink signals are PDCCH / PDSCH / CSI-RS), and the fourth processing rule is used. Optionally, the fourth processing rule and the ninth processing rule are used at the same time.

[0398] Specifically, DL#1 is received, and reception of DL#2 and DL#3 is canceled.

[0533] Based on the above processing rules, the terminal 101 can determine whether to send the uplink signal according to different situations of the symbol types that can be used for an uplink transmission.

[0534] Case 3-1: The first symbol of the uplink signal is a semi-static flexible symbol Semi-F. The network device 102 configures the DCI to indicate the symbol type of the terminal 101. The terminal 101 does not detect the DCI sent by the network device 102 to indicate the symbol type.

[0535] Case 3-1-1: The second information is DCI. The uplink signal is at least one of PUCCH, PUSCH, PRACH, and SRS.

[0536] The terminal 101 may determine whether to send an uplink signal based on the twenty-third processing rule.

[0537] Case 3-1-2: The second information is high-layer signaling, and the first configuration is configured, where the first configuration is used to indicate that the terminal is allowed to use flexible symbols for uplink transmission. The uplink signal is at least one of PUCCH, PUSCH, PRACH, and SRS.

[0538] The terminal 101 may determine whether to send an uplink signal based on the twenty-third processing rule.

[0539] Case 3-1-3: The second information is high-layer signaling, and the first configuration is not configured. The first configuration is used to indicate that the terminal is allowed to use flexible symbols for uplink transmission. The uplink signal is any one of the first category uplink signals, and the first category uplink signals do not include SRS. Exemplarily, the first category uplink signal includes at least one of PUCCH, PUSCH, and PRACH.

[0540] If the terminal 101 does not have the partial cancellation capability, it determines whether to send an uplink signal based on the twenty-seventh processing rule.

[0541] If the terminal 101 has a partial cancellation capability, it determines whether to send an uplink signal based on the twenty-eighth processing rule.

[0542] Case 3-1-4: The second information is high-layer signaling, and the first configuration is not configured. The first configuration is used to indicate that the terminal is allowed to use flexible symbols for uplink transmission. The uplink signal is any one of the second type of uplink signals, and the second type of uplink signal includes an SRS. Exemplarily, the second type of uplink signal includes at least an SRS.

[0543] The terminal 101 may determine whether to send an uplink signal based on the twenty-eighth processing rule.

[0544] Case 3-2: The network device 102 is not configured with a dynamic signaling indicator symbol type, that is, the DCI indicator symbol type is not configured as SFI-SBFD / SFI-D / SFI-U / SFI-F.

[0545] Case 3-2-1: The symbol types that can be used in an uplink transmission include SBFD symbols and non-SBFD symbols.

[0546] The second information may be high-layer signaling or dynamic signaling, and the uplink signal may be at least one of PUCCH, PUSCH, PRACH, and SRS. In this case, the terminal 101 may determine whether to send the uplink signal based on the twenty-second processing rule.

[0547] Case 3-2-2: The symbol types that can be used for one transmission include SBFD symbols or non-SBFD symbols.

[0548] The second information may be high-layer signaling or dynamic signaling, and the uplink signal may be at least one of PUCCH, PUSCH, PRACH, and SRS. In this case, the terminal 101 may determine whether to send the uplink signal based on the twenty-second processing rule and the twenty-fourth processing rule.

[0549] Case 3-2-3: The symbol types that can be used for one transmission include only SBFD symbols.

[0550] The second information may be high-layer signaling or dynamic signaling, and the uplink signal may be at least one of PUCCH, PUSCH, PRACH, and SRS. In this case, the terminal 101 may determine whether to send the uplink signal based on the twenty-second processing rule and the twenty-fifth processing rule.

[0551] Case 3-2-4: The symbol types that can be used for one transmission include only non-SBFD symbols.

[0552] The second information may be high-layer signaling or dynamic signaling, and the uplink signal may be at least one of PUCCH, PUSCH, PRACH, and SRS. In this case, the terminal 101 may determine whether to send the uplink signal based on the twenty-second processing rule and the twenty-sixth processing rule.

[0553] For example, as shown in Figure 2D , the first information is high-layer signaling, and the first signal is an uplink signal. In timeslot #2, OS#0-OS#7 are Semi-D, and OS#8-OS#13 are Semi-SBFD. In timeslot #3, OS#0-OS#1 are Semi-D, and OS#2-OS#13 are Semi-F. The second set includes OS#2-OS#13 in timeslot #2 and OS#0-OS#3 in timeslot #3.

[0554] Among them, uplink signal UL#1 is on OS#2-OS#11 in time slot #3. UL#2 is on OS#4-OS#13 in time slot #3. UL#3 is on OS#0-OS#7 in time slot #3. UL#4 is on OS#5-OS#9 in time slot #2. UL#5 is on OS#10-OS#13 in time slot #2.

[0555] An uplink transmission can be in SBFD symbols or non-SBFD symbols, or an uplink transmission can be in SBFD and non-SBFD symbols, or an uplink transmission can only be in SBFD symbols, or an uplink transmission can only be in non-SBFD symbols:

[0556] The first set is Semi-F, and the network device 102 configures the dynamic signaling indicator symbol type as SFI-SBFD / SFI-D / SFI-U / SFI-F, but the terminal 101 does not detect the dynamic signaling. When UL#1 / UL#2 is Dynamic-U (PUCCH, PUSCH, PRACH, SRS):

[0557] Terminal 101 transmits UL#1 and UL#2 using the twenty-third processing rule.

[0558] Terminal 101 is configured with the first configuration enableConfiguredUL:

[0559] When UL#1 / UL#2 is RRC-U (PUCCH / PUSCH / PRACH / SRS): use the 23rd processing rule to send UL#1 and UL#2.

[0560] Terminal 101 is not configured with the first configuration enableConfiguredUL:

[0561] When UL#1 / UL#2 is RRC-U (PUCCH / PUSCH / PRACH):

[0562] When the terminal 101 does not support the partialCancellation capability, the twenty-seventh processing rule is used to send UL#1 and cancel the sending of UL#2.

[0563] When the UE supports the partialCancellation capability, the 28th processing rule is used to cancel the sending of UL#1 in OS#4-OS#11, send UL#1 in OS#2-OS#3, and cancel the sending of UL#2.

[0564] When UL#1 / UL#2 is RRC-U(SRS):

[0565] Using the twenty-eighth processing rule, the transmission of UL#1 is canceled in OS#4-OS#11, the transmission of UL#1 is canceled in OS#2-OS#3, and the transmission of UL#2 is canceled.

[0566] The following embodiment is applicable to the case where the dynamic signaling indicator symbol type is not configured as SFI-SBFD / SFI-D / SFI-U / SFI-F.

[0567] When an uplink transmission can be in SBFD symbols and non-SBFD symbols:

[0568] UL#1 to UL#5 are RRC-U (PUCCH, PUSCH, PRACH, SRS) / Dynamic-U (PUCCH, PUSCH, PRACH, SRS), using the 22nd processing rule, sending UL#1, UL#2 and UL#5, and canceling the sending of UL#3 and UL#4.

[0569] When a transmission can be in SBFD symbols or non-SBFD symbols:

[0570] UL#1 to UL#5 are RRC-U (PUCCH, PUSCH, PRACH, SRS) / Dynamic-U (PUCCH, PUSCH, PRACH, SRS), using the 22nd and 24th processing rules, UL#1, UL#2 and UL#5, and canceling the transmission of UL#3 and UL#4.

[0571] When a transmission is only possible in SBFD symbols:

[0572] UL#1 to UL#5 are RRC-U (PUCCH, PUSCH, PRACH, SRS) / Dynamic-U (PUCCH, PUSCH, PRACH, SRS), use the 22nd and 25th processing rules, send UL#5, and cancel sending UL#1 to UL#4.

[0573] When a transmission is only possible in non-SBFD symbols:

[0574] UL#1 to UL#5 are RRC-U (PUCCH, PUSCH, PRACH, SRS) / Dynamic-U (PUCCH, PUSCH, PRACH, SRS), using the 22nd and 26th processing rules to send UL#1 and UL#2, and cancel the sending of UL#3, UL#4 and UL#5.

[0575] The above description is merely an example. All solutions in which the terminal 101 determines whether to receive or send the first signal based on different processing rules should fall within the scope of protection of the present disclosure.

[0576] In step S2106 , the network device 102 determines whether the terminal 101 has received or sent the first signal.

[0578] In some embodiments, network device 102 may send instruction information to terminal 101, instructing terminal 101 to send or not send an uplink signal. When instructing terminal 101 to send an uplink signal, network device 102 receives the uplink signal. When instructing terminal 101 to receive a downlink signal, network device 102 may not repeatedly transmit the downlink signal.

[0579] In some embodiments, network device 102 uses the same processing rules as terminal 101 to determine whether terminal 101 has received or sent the first signal. The method by which network device 102 determines whether terminal 101 has received or sent the first signal is similar to the method by which terminal 101 determines whether it has received or sent the first signal, and is not further described herein.

[0614] FIG3B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3B , the embodiment of the present disclosure relates to a communication method, which can be executed by the network device 102, and the method includes:

[0615] Step S3201, sending the first information.

[0616] In some embodiments, the network device 102 may send the first information based on the symbol type of the symbol.

[0617] In some embodiments, the first information is used to determine a symbol type of the symbol.

[0618] In some embodiments, the network device 102 may send the first information to the terminal 101 .

[0619] In some embodiments, terminal 101 receives first information.

[0620] In some embodiments, the optional implementation of step S3201 can refer to the optional implementation of step S2101 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0623] In some embodiments, the second information is used to determine at least one of a time domain resource and a frequency domain resource used by the first signal.

[0624] In some embodiments, the network device 102 may send the second information to the terminal 101 .

[0626] In some embodiments, the optional implementation of step S3202 can refer to the optional implementation of step S2103 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0627] Step S3203: Determine whether the terminal 101 receives or sends the first signal.

[0628] In some embodiments, the optional implementation of step S3203 can refer to the optional implementation of step S2106 in Figure 2A and other related parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0629] In some embodiments, the communication method involved in the embodiments of the present disclosure may include at least one of steps S3201 to S3203. For example, step S3201 can be implemented as an independent embodiment, step S3202 can be implemented as an independent embodiment, steps S3201+S3202 can be implemented as an independent embodiment, step S3203 can be implemented as an independent embodiment, and steps S3201 to S3203 can be implemented as independent embodiments, but are not limited thereto.

[0630] In the above embodiment, the network device considers the different frequency domain ranges of the first-direction transmission on SBFD symbols and non-SBFD symbols, as well as the impact of the symbol types that can be used for one transmission on the processing rules, thereby determining whether the terminal has received or sent the first signal, maintaining consistency with the terminal side's understanding of the terminal behavior, and improving the availability and flexibility of SBFD.

[0631] In the above embodiment, the OS (OFDM symbol) is used as an example, and the present solution does not limit the symbol type to the OFDM symbol.

[0632] The above scheme is further illustrated below with examples.

[0633] Terminal side:

[0634] Step 1: Receive first information, the first information including symbol category configuration / indication information, and determine the symbol category of each symbol.

[0635] In one example, the first information includes high-layer signaling and / or dynamic signaling. The high-layer signaling can configure a symbol as SBFD / DL / UL / F (which can be written as Semi-SBFD / D / U / F), and the dynamic signaling can indicate a symbol as SBFD / DL / UL / F (which can be written as SFI-SBFD / DL / UL / F).

[0636] Step 2: Receive second information, which includes information such as the time-frequency resource location of the DL signal / UL signal, and determine the time-frequency resources used by the DL / UL signal.

[0637] In one example, the time-frequency resource location of the DL signal / UL signal is indicated by higher layer configuration and / or DCI, the DL signal includes PDCCH, PDSCH, CSI-RS, DL PRS, and the UL signal includes PUCCH, PUSCH, PRACH, and SRS.

[0638] The signal frequency domain range determination scheme is as follows:

[0639] The first determination method: if the symbol where the signal is located is non-SBFD, the second frequency domain range is used; if the symbol where the signal is located is SBFD, the third frequency domain range is used.

[0640] Second determination method: if the symbol where the signal is located is non-SBFD, use the second frequency domain range; if the symbol where the signal is located is SBFD, use the fourth frequency domain range.

[0641] The third determination method: the signal uses the third frequency domain range or the fourth frequency domain range.

[0642] Fourth determination method: the signal uses the second frequency domain range.

[0643] The second frequency domain range is a frequency domain range used by a signal in a non-SBFD symbol configured by RRC or a frequency domain range used by a signal indicated by DCI.

[0644] The third frequency domain range is a frequency domain range that overlaps the second frequency domain range and the first direction frequency domain range used by the first BWP.

[0645] The fourth frequency domain range is the frequency domain range used by the first signal configured by the second information on the SBFD symbol.

[0646] Optionally, for RRC-D (the downlink signal is any one of PDCCH, PDSCH, CSI-RS, DL PRS), the frequency domain range is determined using the first determination method, the second determination method, the third determination method, or the fourth determination method, and for Dynamic-D (the downlink signal is any one of PDSCH, CSI-RS), the frequency domain range is determined using the first determination method.

[0647] Optionally, for RRC-U (the uplink signal is any one of PUCCH, PUSCH, PRACH, SRS), the frequency domain range is determined using the first determination method, the second determination method, the third determination method, or the fourth determination method, and for Dynamic-U (the uplink signal is any one of PUCCH, PUSCH, PRACH, SRS), the frequency domain range uses the first determination method.

[0648] Based on the DL frequency domain range, it can be determined whether the DL signal frequency domain range on the SFI-SBFD symbol in the symbol where the DL signal is located overlaps with the first frequency domain range (outside the DL transmission frequency domain range):

[0649] No overlap: When the DL signal frequency domain range is determined using the fourth determination method, it is determined that the frequency domain range used by the DL signal does not overlap with the DL transmission frequency domain range; or, the DL signal frequency domain range is determined using any one of the first determination method, the second determination method, and the third determination method. At this time, it is determined that the frequency domain range used by the DL signal does not overlap with the DL transmission frequency domain range.

[0650] Overlapping: The DL signal frequency domain range is determined using the fourth determination method. In this case, it is determined that the frequency domain range used by the DL signal overlaps with the DL transmission frequency domain range.

[0651] Whether the UL signal frequency domain range on the SFI-SBFD symbol in the symbol where the UL signal is located overlaps with the first frequency domain range (outside the UL transmission frequency domain range):
