[0146] FIG2A is an interactive diagram illustrating a method for determining uplink transmission behavior according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a method for determining uplink transmission behavior, the method comprising:

[0147] Step S2101 , the network device 102 sends an indication signaling to the terminal 101 .

[0148] In some embodiments, terminal 101 receives the indication signaling.

[0149] In some embodiments, the name of the indication signaling is not limited, and it can be, for example, an indication message, a first message, a first signaling, etc.

[0150] In some embodiments, the network device 102 determines that a first time domain resource occupied by a synchronization signal block (Synchronization Signal / PBCH Block, SSB) conflicts with a second time domain resource occupied by an uplink transmission of the terminal on an uplink subband, and sends the indication information to the terminal 101.

[0151] In some embodiments, network device 102 periodically transmits SSB.

[0152] In some embodiments, the uplink subband is located within a first type of time unit, which may be defined as a Subband-Based Full Duplex (SBFD) time unit, such as shown in FIG. 2B .

[0153] In some embodiments, the uplink subband is located in a downlink (DL) time unit or a flexible time unit in the time domain.

[0154] In some embodiments, the time unit may be a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or a span, which is not limited in the present disclosure. A span includes multiple consecutive symbols.

[0155] In some embodiments, the uplink transmission is used to transmit at least one of the following: a physical uplink shared channel (PUSCH) scheduled by downlink control information (DCI); a semi-static PUSCH (Configured Grant-PUSCH, CG-PUSCH) triggered by DCI; a physical uplink control channel (PUCCH) corresponding to a physical downlink shared channel (PDSCH) scheduled by DCI; an uplink reference signal triggered by DCI; a periodically transmitted PUSCH configured by radio resource control (RRC) signaling; and a periodically transmitted PUCCH configured by RRC signaling.

[0156] The uplink reference signal includes but is not limited to a channel sounding reference signal (Sounding Reference Signal, SRS).

[0157] In some embodiments, the conflict between the first time domain resource occupied by the synchronization signal block SSB and the second time domain resource occupied by the uplink transmission of the terminal on the uplink subband includes but is not limited to at least one of the following: the first time domain resource and the second time domain resource completely overlap, as shown in Figure 2C; the first time domain resource and the second time domain resource partially overlap, as shown in Figure 2D; the first time domain resource and the second time domain resource do not overlap, but are located in the same time unit, as shown in Figure 2E.

[0158] In some embodiments, the indication signaling includes but is not limited to DCI, Media Access Control Element (MAC CE), RRC signaling, etc.

[0159] In some embodiments, the network device 102 instructs the terminal 101 to start repeated transmission of a physical uplink channel, wherein the physical uplink channel includes but is not limited to PUCCH and PUSCH.

[0160] In some embodiments, the indication signaling may be used to indicate whether the time unit in which the SSB is located can be used to perform uplink transmission.

[0161] For example, the indication signaling may occupy 1 bit, and the indication signaling bit value is "1" to indicate that the time unit where the SSB is located can be used for uplink transmission. The indication signaling bit value is "0" to indicate that the time unit where the SSB is located cannot be used for uplink transmission.

[0162] Exemplarily, the indication signaling may occupy 1 bit, and the indication signaling bit value is "0" to indicate that the time unit where the SSB is located can be used for uplink transmission. The indication signaling bit value is "1" to indicate that the time unit where the SSB is located cannot be used for uplink transmission.

[0163] In some embodiments, the indication signaling may be used to indicate whether each SSB opportunity included in the SSB burst set can be used to perform uplink transmission.

[0164] The SSB occasion is the time point when the network device sends the SSB.

[0165] Exemplarily, the indication signaling may use a bitmap to indicate whether each SSB opportunity included in the SSB burst set can be used to perform uplink transmission.

[0166] For example, an SSB burst set includes N SSB opportunities, where N is a positive integer, such as 1, 2, 3, etc. The indication signaling may occupy N bits, and the value of each bit indicates whether the SSB opportunity can be used for uplink transmission.

[0167] Assume that a bit value of "1" indicates that the corresponding SSB opportunity can be used for uplink transmission, and a bit value of "0" indicates that the corresponding SSB opportunity cannot be used for uplink transmission. If N is 6 and the indication signaling is 110010, then the indication signaling is used to indicate that the 1st, 2nd, and 5th SSB opportunities can be used for uplink transmission.

[0168] Step S2102: Terminal 101 determines uplink transmission behavior.

[0169] In some embodiments, the terminal 101 determines the uplink transmission behavior based on the received indication signaling.

[0170] In some embodiments, terminal 101 determines whether to perform uplink transmission on the uplink subband based on the received indication signaling. In some embodiments, the indication signaling includes DCI, and terminal 101 determines to perform uplink transmission on the uplink subband. That is, terminal 101 does not receive the SSB sent by network device 102.

[0171] In some embodiments, the indication signaling includes DCI, and the network device 102 instructs the terminal 101 to enable repeated transmission of the physical uplink channel. The terminal 101 determines to repeatedly transmit the physical uplink channel for a first number of times on the uplink subband. The first number is less than the total number of repeated transmissions and is a positive integer.

[0172] Exemplarily, the network device 102 instructs the terminal 101 to enable PUSCH retransmission or transport block processing over Multi-Slot pusch (TBoMS), and the terminal 101 determines to retransmit the first number of PUSCHs on the uplink subband.

[0173] Exemplarily, the network device 102 instructs the terminal 101 to enable repeated transmission of the PUCCH, and the terminal 101 determines to repeatedly transmit the PUCCH for the first number of times on the uplink subband.

[0174] Assuming that the total number of repeated transmissions of the physical uplink channel is 32, the first number may be a positive integer less than 32, such as 1, 2, 3, ..., 31.

[0175] In some embodiments, the terminal 101 determines a new uplink transmission behavior based on predefined rules, and the new uplink transmission behavior includes whether to repeatedly transmit the physical uplink channel a second time on the uplink subband, and the second time is equal to the difference between the total time and the first time.

[0176] In the embodiment of the present disclosure, when uplink channel repeated transmission is enabled, the terminal 101 may combine the indication signaling with the predefined rules to jointly determine the uplink transmission behavior of the terminal.

[0177] Exemplarily, the terminal 101 determines, based on the received indication signaling, a physical uplink channel for repeated transmission of the first number of times on the uplink subband.

[0178] Furthermore, the terminal determines whether to repeatedly transmit the physical uplink channel for a second time on the uplink subband based on a predefined rule. The manner in which the terminal 101 determines whether to repeatedly transmit the physical uplink channel for a second time on the uplink subband based on a predefined rule will be described in subsequent embodiments and will not be described here for the time being.

[0179] Exemplarily, the terminal 101 determines, based on a predefined rule, a physical uplink channel for repeating transmission a second number of times on the uplink subband.

[0180] Exemplarily, the terminal 101 determines not to repeatedly transmit the physical uplink channel a second time on the uplink subband based on a predefined rule.

[0181] In some embodiments, the terminal 101 determines a new uplink transmission behavior based on whether new indication signaling is received, and the new uplink transmission behavior includes whether to repeatedly transmit the physical uplink channel for a second time on the uplink subband, and the second number of times is equal to the difference between the total number of times and the first number of times.

[0182] Exemplarily, the terminal 101 receives new indication signaling and determines to repeatedly transmit the physical uplink channel for a second number of times on the uplink subband.

[0183] Exemplarily, the terminal 101 does not receive any new indication signaling and determines not to repeatedly transmit the physical uplink channel for a second time on the uplink subband.

[0184] Assume the total number is 32, the first number is 16, and the second number is also 16. After terminal 101 performs 16 repeated transmissions of the physical uplink channel on the uplink subband based on the instruction signaling sent by network device 102, it does not receive new instruction signaling from network device 102. Terminal 101 determines not to perform the remaining 16 repeated transmissions of the physical uplink channel on the uplink subband. At this time, terminal 101 can receive the SSB sent by network device 102.

[0185] That is, for the terminal 101 , the remaining number of repeated transmissions of the physical uplink channel may be re-determined based on a predefined rule or a new indication signaling sent by the network device 102 .

[0186] In some optional embodiments, for uplink transmission semi-statically configured by the network device 102, such as a semi-static PUSCH triggered by a DCI, the terminal 101 does not expect to perform uplink transmission on an SSB symbol.

[0187] In some embodiments, the indication signaling is used to indicate whether the time unit in which the SSB is located can be used for uplink transmission. Based on the indication signaling, the terminal 101 performs uplink transmission on the uplink subband within a first time unit, where the first time unit is a time unit in which the SSB is located and can be used for uplink transmission.

[0188] Based on the indication signaling, the terminal 101 can receive the SSB sent by the network device 102 within the second time unit where the uplink subband is located. The second time unit is a time unit where the SSB is located and cannot be used to perform uplink transmission.

[0189] In some embodiments, the indication signaling is used to indicate whether each SSB opportunity included in the SSB burst set can be used for uplink transmission. Based on the indication signaling, the terminal 101 performs uplink transmission on the uplink subband within the first SSB opportunity, where the first SSB opportunity is an SSB opportunity that can be used for uplink transmission.

[0190] Based on the indication signaling, the terminal 101 can receive the SSB sent by the network device 102 on the second SSB opportunity where the uplink subband is located. The second SSB opportunity is an SSB opportunity that cannot be used to perform uplink transmission.

[0191] In some embodiments, step S2101 is an optional step, that is, the terminal 101 can directly determine the uplink transmission behavior based on the predefined rules.

[0192] In some embodiments, the predefined rules include but are not limited to determining the uplink transmission behavior based on the relationship between the number of first resource blocks (RBs) spaced between the first frequency domain resources and the second frequency domain resources and the number of second RBs used as a reference.

[0193] In some optional embodiments, the second number of RBs may be the number of RBs included in the guard band. The interval between frequency bands does not have a transmission function, so it is called a guard band.

[0194] In some optional embodiments, the second number of RBs may be the number of RBs included in the first gap (GAP), wherein the first GAP may be configured by the network device 102 or predefined by a protocol.

[0195] In some optional embodiments, the number of first resource blocks (RBs) between the first frequency domain resources and the second frequency domain resources is a positive integer multiple of the number of second RBs used as a reference, and the terminal 101 determines to perform uplink transmission on the uplink subband.

[0196] For example, the first number of RBs is equal to the second number of RBs, or the first number of RBs is 2 times, 3 times, etc. the second number of RBs, and the terminal 101 may determine to perform uplink transmission on the uplink subband.

[0197] If the first RB number is not a positive integer multiple of the second RB number, the terminal 101 can receive the SSB sent by the network device 102.

[0198] In some optional embodiments, when repeated transmission of the physical uplink channel is enabled, the terminal 101 determines, based on the received indication signaling, to repeatedly transmit the physical uplink channel for the first number of times on the uplink subband.

[0199] Furthermore, the terminal determines a new uplink transmission behavior based on a predefined rule, the new uplink transmission behavior including whether to repeatedly transmit the physical uplink channel a second number of times on the uplink subband, the second number of times being equal to the difference between the total number of times and the first number of times.

[0200] Exemplarily, the number of first resource blocks RBs between the first frequency domain resources and the second frequency domain resources is a positive integer multiple of the second RB number used as a reference, and the terminal 101 determines to repeatedly transmit the physical uplink channel a second time on the uplink subband.

[0201] Exemplarily, the first number of RBs is not a positive integer multiple of the second number of RBs used as a reference, and the terminal 101 determines not to repeatedly transmit the second number of physical uplink channels on the uplink subband.

[0202] In step S2103 , the network device 102 determines the uplink transmission behavior of the terminal 101 .

[0203] In some embodiments, the network device 102 determines the uplink transmission behavior of the terminal 101 based on the sent indication signaling.

[0204] In some embodiments, the network device 102 determines whether the terminal 101 performs uplink transmission on the uplink subband based on the sent indication signaling.

[0205] In some optional embodiments, the network device 102 determines that the terminal 101 performs uplink transmission on the uplink subband, then the network device 102 may receive the channel or signal of the uplink transmission, and the network device 102 may not send the SSB.

[0206] In some optional embodiments, if the network device 102 determines that the terminal 101 does not perform uplink transmission on the uplink subband, the network device 102 may send the SSB.

[0207] In some embodiments, the indication signaling includes DCI, and network device 102 determines that terminal 101 performs uplink transmission on the uplink subband. That is, terminal 101 will not receive the SSB sent by network device 102. Accordingly, network device 102 may receive the uplink transmission channel or signal on the uplink subband and not send the SSB.

[0208] In some embodiments, the indication signaling includes DCI, and network device 102 indicates to terminal 101 that repeated transmission of a physical uplink channel has been enabled. Network device 102 determines that terminal 101 repeatedly transmits the physical uplink channel for a first number of times on the uplink subband. The first number is less than the total number of repeated transmissions and is a positive integer.

[0209] Exemplarily, the network device 102 instructs the terminal 101 to enable PUSCH retransmission or TBoMS, and the network device 102 determines that the terminal 101 retransmits the first number of PUSCHs on the uplink subband.

[0210] Exemplarily, the network device 102 instructs the terminal 101 to enable repeated transmission of the PUCCH, and the network device 102 determines that the terminal 101 repeatedly transmits the first number of PUCCHs on the uplink subband.

[0211] Assuming that the total number of repeated transmissions of the physical uplink channel is 32, the first number may be a positive integer less than 32, such as 1, 2, 3, ..., 31.

[0212] In some embodiments, the network device 102 determines a new uplink transmission behavior of the terminal 101 based on a predefined rule or a new indication signaling sent to the terminal 101. The new uplink transmission behavior includes whether to repeatedly transmit the physical uplink channel a second time on the uplink subband, and the second number of times is equal to the difference between the total number of times and the first number of times.

[0213] For the network device 102, whether the terminal 101 performs the remaining repeated transmission of the physical uplink channel can be determined based on predefined rules, or based on whether new indication signaling is sent to the terminal 101.

[0214] Exemplarily, the network device 102 sends a new indication signaling to the terminal 101, and the network device 102 determines that the terminal 101 repeats the transmission of the physical uplink channel for a second number of times on the uplink subband.

[0215] Exemplarily, the network device 102 does not send new indication signaling to the terminal 101, and determines that the terminal 101 does not repeatedly transmit the physical uplink channel for the second time on the uplink subband.

[0216] Assume that the total number is 32, the first number is 16, and the second number is also 16. After network device 102 determines that terminal 101 has performed 16 repeated transmissions of the physical uplink channel on the uplink subband based on the instruction signaling sent to terminal 101, if network device 102 does not send new instruction signaling to terminal 101, network device 102 determines that terminal 101 will not perform the remaining 16 repeated transmissions of the physical uplink channel on the uplink subband. At this time, network device 102 can send the SSB to terminal 101.

[0217] Exemplarily, the network device 102 determines, based on a predefined rule, that the terminal 101 repeats transmitting the physical uplink channel for a second number of times on the uplink subband.

[0218] Exemplarily, the network device 102 determines, based on a predefined rule, that the terminal 101 does not repeatedly transmit the physical uplink channel for a second time on the uplink subband.

[0219] In some optional embodiments, for uplink transmission semi-statically configured by the network device 102, such as a semi-static PUSCH triggered by a DCI, the network device 102 does not receive the uplink transmission of the terminal on an SSB symbol.

[0220] In some embodiments, the indication signaling is used to indicate whether the time unit in which the SSB is located can be used for uplink transmission. The network device 102 determines that the terminal 101 performs uplink transmission on the uplink subband within a first time unit based on the indication signaling, where the first time unit is a time unit in which the SSB is located and can be used for uplink transmission.

[0221] The network device 102 determines that the terminal 101 receives the SSB sent by the network device 102 within the second time unit where the uplink subband is located based on the indication signaling. The second time unit is a time unit where the SSB is located and cannot be used to perform uplink transmission.

[0222] In some embodiments, the indication signaling is used to indicate whether each SSB opportunity included in the SSB burst set can be used for uplink transmission. An SSB burst is a time range within an SSB transmission period during which a cell transmits all SSBs. Network device 102 determines, based on the indication signaling, that terminal 101 performs uplink transmission on the uplink subband within a first SSB opportunity, where the first SSB opportunity is an SSB opportunity that can be used for uplink transmission.

[0223] The network device 102 determines that the terminal 101 can receive the SSB sent by the network device 102 on the second SSB opportunity where the uplink subband is located based on the indication signaling, and the second SSB opportunity is an SSB opportunity that cannot be used to perform uplink transmission.

[0224] In some embodiments, step S2101 is an optional step, that is, the network device 102 can directly determine the uplink transmission behavior of the terminal 101 based on predefined rules.

[0225] In some embodiments, the predefined rules include but are not limited to determining the uplink transmission behavior of the terminal 101 based on the relationship between the number of first resource blocks (RBs) spaced between the first frequency domain resources and the second frequency domain resources and the number of second RBs used as a reference.

[0226] In some optional embodiments, the second number of RBs may be the number of RBs included in a guard band.

[0227] In some optional embodiments, the second number of RBs may be the number of RBs included in the first gap (GAP), wherein the first GAP may be configured by the network device 102 or predefined by a protocol.

[0228] In some optional embodiments, the number of first resource blocks (RBs) between the first frequency domain resources and the second frequency domain resources is a positive integer multiple of the number of second RBs used as a reference, and the terminal 101 determines to perform uplink transmission on the uplink subband.

[0229] For example, the first number of RBs is equal to the second number of RBs, or the first number of RBs is 2 times, 3 times, etc. the second number of RBs, and the terminal 101 may determine to perform uplink transmission on the uplink subband.

[0230] If the first RB number is not a positive integer multiple of the second RB number, the network device 102 determines that the terminal 101 receives the SSB sent by the network device 102.

[0231] In some embodiments, the uplink transmission is used to transmit at least one of the following: PUSCH scheduled by DCI; semi-static PUSCH triggered by DCI; PUCCH corresponding to PDSCH scheduled by DCI; uplink reference signal triggered by DCI; PUSCH configured for periodic transmission through RRC signaling; PUCCH configured for periodic transmission through RRC signaling.

[0232] In one example, the network device 102 schedules, triggers or configures the terminal to perform the above-mentioned uplink transmission through DCI or RRC signaling. The DCI or RRC signaling can also serve as indication signaling so that the terminal 101 can determine the uplink transmission behavior.

[0233] Exemplarily, the terminal 101 receives DCI sent by the network device 102, where the DCI is used to schedule PUSCH. The terminal 101 determines to perform uplink transmission on the uplink subband based on the DCI. Specifically, the terminal 101 can transmit the PUSCH scheduled by the DCI on the uplink subband.

[0234] Exemplarily, terminal 101 receives RRC signaling sent by network device 102, where RRC signaling is used to configure PUCCH for periodic transmission. Terminal 101 determines to perform uplink transmission on the uplink subband based on the RRC signaling. Specifically, terminal 101 can transmit the PUCCH configured by the RRC signaling on the uplink subband.

[0235] In some embodiments, the uplink transmission is used to transmit at least one of the following: PUSCH scheduled by DCI; semi-static PUSCH triggered by DCI; PUCCH corresponding to PDSCH scheduled by DCI; uplink reference signal triggered by DCI; PUSCH configured for periodic transmission through RRC signaling; PUCCH configured for periodic transmission through RRC signaling.

[0236] Terminal 101 receives the above DCI or RRC signaling. When terminal 101 determines that the first time domain resource occupied by the synchronization signal block SSB conflicts with the second time domain resource occupied by the uplink transmission of terminal 101 on the uplink subband, terminal 101 directly determines the uplink transmission behavior of terminal 101 based on the predefined rule.

[0237] For example, terminal 101 receives DCI sent by network device 102, where the DCI is used to schedule a PUSCH. However, terminal 101 determines based on a predefined rule not to perform uplink transmission on an uplink subband. Therefore, although network device 102 sends DCI, terminal 101 may not transmit the PUSCH scheduled by the DCI on the uplink subband.

[0292] In some embodiments, step S4201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0293] In the above embodiment, the network device can clarify the terminal behavior based on predefined rules when the SSB and the uplink transmission of the terminal on the uplink subband conflict in the time domain.

[0294] The above solution provided in the embodiment of the present disclosure is further illustrated below with examples.

[0295] Terminal 101:

[0296] When the SSB sent by the network device 102 conflicts with the uplink transmission on the uplink subband (UL subband) in time domain resources, the terminal determines whether the uplink transmission can be sent according to a predefined rule or an indication signaling sent by the network device 102.

[0297] Method 1: For uplink transmission scheduled or triggered by DCI, the terminal sends uplink within the UL subband range according to the instruction of the DCI.

[0298] The uplink transmission includes at least one of the following uplink channels or signals: PUSCH scheduled by DCI, Type-2 CG PUSCH triggered by DCI, PUCCH transmission corresponding to PDSCH scheduled by DCI, SRS triggered by DCI, PUSCH with periodic transmission configured by radio resource control RRC signaling, PUCCH with periodic transmission configured by RRC signaling, etc.

[0299] Furthermore, if the network device 102 instructs the terminal 101 to enable PUSCH repeated transmission or TBoMS, for PUSCH transmissions other than the first one, it is determined whether the PUSCH can be sent in the UL subband according to a predefined method or an instruction from the network device 102 .

[0300] Furthermore, if the network device 102 instructs the terminal 101 to enable repeated PUCCH transmission, for non-first PUCCH transmission, it is determined whether the PUCCH can be sent within the UL subband according to a predefined method or base station indication.

[0301] Furthermore, for the semi-statically configured uplink transmission, the terminal 101 does not expect to send the uplink transmission on the SSB symbol.

[0302] Method 2: Finally, 101 determines whether uplink can be sent within the UL subband of the SSB symbol based on the distance between the UL subband and the SSB in the frequency domain.

[0303] The GAP is the guard band configured by the network device 102, or a multiple of the guard band, or a GAP indicated by the base station, or a GAP predefined by the protocol.

[0304] Method 3: The terminal 101 determines whether it can send uplink in the UL subband of the SSB symbol based on the instruction signaling of the network device 102.

[0305] Terminal 101 receives the indication signaling sent by network device 102 to determine whether the SSB symbol can be used for uplink transmission.

[0306] The indication signaling is a valid pattern of an SSB occasion within an SSB burst.

[0307] Network device 102:

[0308] When the SSB sent by the network device 102 conflicts with the uplink transmission on the UL subband in the time domain resources, the network device 102 notifies the terminal 101 how to handle the relevant conflict through predefined rules or explicit signaling.

[0309] Method 1: For uplink transmission scheduled or initiated by DCI, the network device 102 receives uplink in the UL subband range according to the instruction of the DCI.

[0310] The specific method is as described on the terminal 101 side and will not be repeated here.

[0311] Method 2: The network device 102 determines whether it can receive uplink signals within the UL subband of the SSB symbol based on the distance between the UL subband and the SSB in the frequency domain.

[0312] Correspondingly, the network device 102 receives or does not receive uplink transmission in the UL subband

[0313] Method 3, the network device 102 instructs the terminal 101 to determine whether it can send uplink within the UL subband of the SSB symbol.

[0314] The specific method is as described on the terminal 101 side and will not be repeated here.

[0315] In Example 1, it is assumed that the terminal is a full-duplex capable terminal, that is, the terminal can transmit uplink signals within the UL subband on the DL or flexible symbols, or receive downlink signals within the DL subband on the UL or flexible symbols. It is assumed that the network device 102 is a full-duplex base station, that is, the network device 102 can simultaneously transmit and receive signals at the same time.

[0316] In this embodiment, the UL subband on the DL symbol is used as an example for description. Of course, the method described in this embodiment can be used in other full-duplex scenarios.

[0317] In this embodiment, it is assumed that the network device 102 simultaneously transmits an SSB on an SBFD symbol and schedules or configures the terminal to transmit an uplink channel or uplink signal. The SSB and uplink transmissions overlap in the time domain. Furthermore, the overlap may include overlapping on some OFDM symbols, or completely overlapping on all OFDM symbols, or transmitting the SSB and uplink transmissions in the same SBFD slot without time domain resource overlap. This embodiment does not impose any limitations on this.

[0318] The uplink transmission is an uplink data channel, an uplink control channel, or an uplink signal configured through semi-static signaling, and may also be an uplink data channel, an uplink control channel, or an uplink signal scheduled or indicated by DCI. In this embodiment, it is assumed that the uplink transmission is an uplink transmission scheduled or triggered by DCI, including dynamically scheduled PUSCH, Type-2 CG PUSCH, PUCCH, etc.

[0319] As a specific example, the embodiments of the present disclosure do not impose any restrictions on the time domain resource position occupied by SSB transmission, the transmission configuration of uplink transmission, and the overlapping status of the SSB and uplink transmission in the time domain.

[0320] In this embodiment, when the network device 102 sends an SSB on the same SBFD slot and schedules an uplink transmission in the UL subband, the terminal 101 and the network device 102 determine how to send and receive the uplink transmission according to predefined rules.

[0321] Specifically, the terminal 101 sends the uplink transmission within the UL subband according to the scheduling information carried by the DCI. The uplink transmission includes at least one of the following uplink channels or signals: PUSCH scheduled by DCI, Type-2 CG PUSCH triggered by DCI, PUCCH transmission corresponding to PDSCH scheduled by DCI, SRS triggered by DCI, PUSCH with periodic transmission configured by RRC signaling, PUCCH with periodic transmission configured by RRC signaling, etc. In this embodiment, there is no restriction on whether repeated transmission is enabled for the uplink transmission.

[0322] Example 2: As described in Example 1, in this disclosed embodiment, it is assumed that repeated transmission is enabled for the uplink transmission.

[0323] In the embodiment of the present disclosure, the terminal 101 transmits the first repetition within the UL subband according to the scheduling or instruction information of the network device 102. If other repetitions conflict with the SSB in the time domain, the terminal does not expect to transmit the uplink transmission.

[0324] In embodiment 3, for semi-statically configured uplink transmission, including Type-1 CG PUSCH, periodic PUCCH, and periodic SRS, when it collides with SSB in the time domain, the terminal 101 does not expect to send the uplink transmission on the OFDM symbol that collides with the SSB.

[0325] Embodiment 4, as in the method described in Embodiment 1, in the embodiment of the present disclosure, it is assumed that the uplink transmission sent within the UL subband range includes PUSCH, PUCCH and SRS.

[0326] In this embodiment, the network device 102 and the terminal 101 determine whether they can receive and transmit uplink data within the UL subband range on the OFDM symbol that conflicts with the SSB time domain according to the following method:

[0327] The terminal 101 determines whether it can send uplink in the UL subband of the SSB symbol based on the distance between the UL subband and the SSB in the frequency domain.

[0328] Correspondingly, the network device 102 determines whether it can receive uplink in the UL subband of the SSB symbol according to the distance between the UL subband and the SSB in the frequency domain.

[0329] The GAP is the guard band configured by the network device 102, or a multiple of the guard band, or the GAP indicated by the network device 102, or the GAP predefined by the protocol. This patent does not impose any limitation.

[0330] Furthermore, when the GAP is a guard band, the terminal 101 sends uplink in the UL subband where the SSB has a time domain conflict according to the scheduling information or configuration information of the network device 102 only when the GAP is not zero, that is, when the GAP exists.

[0331] When the GAP is configured by the network device 102, the network device 102 is configured by UE-dedicated signaling or cell-specific signaling, for example, by RRC signaling or SIB1. This patent does not impose any limitation.

[0332] Embodiment 4, as the method described in Embodiment 1, in this embodiment, it is assumed that the uplink transmission sent within the UL subband range includes PUSCH, PUCCH and SRS.

[0333] In the embodiment of the present disclosure, the terminal 101 determines whether it can send uplink in the UL subband of the SSB symbol according to the indication signaling of the network device 102. The indication signaling is indicated by DCI or RRC signaling or SIB1, and this patent does not impose any limitation.

[0334] The indication signaling is a valid pattern indicating that a UL subband that time-domain conflicts with an SSB occasion within an SSB burst set can be used for uplink transmission. The valid pattern is a bitmap. For each bit contained in the bitmap, a 1 indicates that the terminal 101 can transmit uplink data within the UL subband on the corresponding SSB symbol according to the configuration or scheduling of the network device 102, and a 0 indicates that the terminal 101 does not expect to transmit uplink data within the UL subband on the corresponding SSB symbol.

[0335] In the above embodiment, the conflict problem in the time domain between the SSB sent by the network device and the uplink transmission of the terminal on the uplink sub-band can be solved, the terminal behavior is clarified, and the availability and reliability of full-duplex communication are improved.
