[0039] The embodiments of the present disclosure provide a communication method, a terminal, a network device, a communication system, a storage medium, and a computer program product.

[0040] In a first aspect, an embodiment of the present disclosure proposes a communication method executed by a terminal, the method comprising: determining whether there is an invalid period within a first time period, the first time period being a period during which a network device schedules the terminal to send information, and the invalid period being a period during which the terminal is not allowed to send information.

[0041] In the above embodiment, the terminal can accurately determine the uplink and downlink transmission conditions in the first time period by determining whether there is an invalid time period in the first time period, thereby ensuring the validity of data transmission.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal meets at least one of the following conditions:

[0043] Supporting receiving configuration information sent by the network device;

[0044] Supports transmission mode based on physical uplink shared channel repetition type B;

[0045] Support access to non-terrestrial network NTN;

[0046] Supports half-duplex frequency division duplex HD-FDD.

[0047] In the above embodiments, when the terminal meets at least one of the above conditions, it is possible to accurately determine the actual uplink and downlink transmission status of the terminal in the first time period by determining whether there is an invalid time period in the first time period.

[0048] In combination with some embodiments of the first aspect, in some embodiments, before determining whether there is an invalid period within the first time period, it includes: determining that there is a conflict between the first time period and the second time period, and the second time period is the time period determined by the terminal to need to receive information.

[0049] In the above embodiment, when a terminal determines that an uplink or downlink conflict exists, it specifies whether there is an invalid period within the first time period. This facilitates adjusting uplink and downlink scheduling based on the presence of the invalid period when an uplink or downlink conflict occurs, thereby avoiding problems such as information transmission failure or information reception failure, thereby improving system performance. Furthermore, it also avoids terminal resource loss caused by real-time detection of whether there is an invalid period within the first time period.

[0051] In the above embodiment, by determining the intersection of the first time period and the second time period, the specific time period of the uplink and downlink conflict, i.e., the third time period, can be quickly determined. This allows the non-conflicting time periods in the first time period, excluding the third time period, to be quickly determined as valid time periods, thereby facilitating timely transmission of uplink information during the non-conflicting time periods.

The first information solves the problem of uplink and downlink conflict and ensures the validity of data transmission.

[0054] In combination with some embodiments of the first aspect, in some embodiments, determining whether the third time period is an invalid time period based on the first information includes: determining that the terminal receives information in the third time period based on the first information, and determining the third time period as an invalid time period.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A .

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

[0126] In some embodiments, the continuous emergence of new internet applications such as augmented reality (AR) / virtual reality (VR) and vehicle-to-vehicle communication has placed higher demands on wireless communication technology, driving the continuous evolution of wireless communication technology to meet these application needs. Currently, cellular mobile communication technology is in the process of evolving into a new generation of technology. A key feature of this new generation of technology is the flexible configuration that supports multiple service types. Different service types have different requirements for wireless communication technology. For example, the enhanced mobile broadband (eMBB) service type focuses on high bandwidth and high speed; the ultra-reliable low-latency communication (URLLC) service type focuses on high reliability and low latency; and the massive machine type communication (mMTC) service type focuses on a large number of connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission of multiple service types.

[0127] In some embodiments of the present disclosure, satellite communication is considered an important aspect of the future development of wireless communication technology in the research of wireless communication technology. Satellite communication refers to communication performed by radio communication equipment on the ground using satellites as relays. A satellite communication system consists of a satellite part and a ground part. The characteristics of satellite communication are: a large communication range; communication can be carried out between any two points as long as they are within the range covered by the radio waves emitted by the satellite; and it is not easily affected by land disasters (high reliability). As a supplement to the current ground cellular communication system, satellite communication can have the following advantages:

[0128] (1) Extended coverage: For areas that are not covered by current cellular communication systems or are costly to cover, such as oceans, deserts, and remote mountainous areas, satellite communications can be used to solve communication problems.

[0129] (2) Emergency communications: In extreme situations such as disasters such as earthquakes, when cellular communication infrastructure is unavailable, satellite communications can be used to quickly establish communication connections.

[0130] (3) Providing industry applications: For example, for delay-sensitive services with long-distance transmission, satellite communications can be used to reduce the delay of service transmission.

[0131] It can be foreseen that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the intelligent connection of all things.

[0132] In some embodiments, in a satellite communication system, it is possible to support a scenario in which a terminal type with reduced capability (RedCap) operating in Half-Duplex Frequency Division Duplex (HD-FDD) accesses a non-terrestrial network (NTN) network.

[0133] In some embodiments, the conflict problem of uplink and downlink transmission of Redcap supporting HD-FDD can be solved by predefined rules or based on base station or terminal implementation.

[0134] In some embodiments, the following five collision types may be included based on the scheduling type of the transmitted information and the type of the transmitted information:

[0135] (1) Collision between dynamically scheduled transmissions and semi-statically preconfigured transmissions on the same time unit;

[0136] (2) collisions between dynamically scheduled transmissions / receptions and dynamically scheduled receptions / transmissions on the same time unit;

[0137] (3) Collision between semi-static preconfigured transmission / reception and semi-static preconfigured reception / transmission in the same time unit;

[0138] (4) Collision between Synchronization Signal Blocks (SSBs) and uplink transmissions (including semi-static pre-configured uplink transmissions and dynamically scheduled uplink transmissions) in the same time unit;

[0139] (5) Collision between valid RO (random access channel occasion) / Msg.APUSCH (The Physical Uplink Shared Channel) and downlink reception (including semi-statically pre-configured downlink reception and dynamically scheduled downlink reception) in the same time unit.

[0140] In some embodiments, the dynamic scheduling transmission described in the above collision type can be a scheduling indicated by downlink control information (DCI). In the uplink transmission, it includes the transmission of PUSCH, physical uplink control channel (PUCCH), physical random access channel (PRACH) or sounding reference signal (SRS) indicated by DCI. In the downlink transmission, it includes the transmission of physical downlink shared channel (PDSCH) or downlink channel state information reference signal (CSI-RS) indicated by DCI. Semi-static preconfigured transmission can be a time-frequency resource preconfigured for transmission through radio resource control (RRC) signaling, and information is transmitted within the preset time-frequency resources. The downlink transmission includes the pre-configured PDCCH (type 0 / 0A / 1 / 2 CSS), PDSCH, CSI-RS or downlink positioning reference signal (DL PRS), while the uplink transmission includes the pre-configured PUSCH, PUCCH and SRS.

[0141] In some embodiments, collisions between dynamically scheduled transmit / receive and dynamically scheduled receive / transmit include the following:

[0142] Dynamic scheduling strategies are determined by the network, which typically performs dynamic scheduling based on the terminal's capabilities. For HD-FDD terminals that cannot transmit and receive simultaneously, the network will not schedule them to transmit and receive simultaneously. Therefore, this type of collision can be resolved through network scheduling. On the terminal side, the terminal does not expect the received PDCCH to indicate transmission and reception in the same time unit.

[0143] In some embodiments, the collision between semi-static pre-configured transmission / reception and semi-static pre-configured reception / transmission includes the following:

[0144] Similar to the collision between dynamically scheduled transmit / receive and dynamically scheduled receive / transmit, since the semi-static transmission configuration is determined by the network, the network will not pre-configure HD-FDD to transmit and receive simultaneously. Therefore, on the terminal side, the terminal does not expect the pre-configured information to be configured to transmit and receive in the same time unit.

[0145] In some embodiments, collisions between dynamically scheduled transmissions and semi-statically preconfigured transmissions include the following:

[0146] Since this type of collision already exists in the Rel-15 NR TDD system, HD-FDD reuses the processing method in the Rel-15 TDD system.

[0147] When the preconfigured transmission is downlink reception and the dynamic scheduling is uplink transmission, as long as any scheduled uplink transmission symbol is the same as the downlink reception symbol, the current preconfigured downlink reception is abandoned.

[0148] When the pre-configured transmission is uplink sending and the dynamic scheduling is downlink receiving, it is necessary to first determine the timing of the transmission and then determine whether to cancel the policy based on the timing.

[0149] Assume that the time corresponding to the last symbol of the CORESET (control resource set) to which the DCI detected by the terminal belongs is k. If the first symbol of the pre-configured uplink PUSCH / PUSCH is between k and k+T proc,2 During this time period, in this case, the terminal does not cancel the pre-configured PUSCH / PUCCH transmission. Otherwise, the terminal cancels the PUSCH / PUCCH, or an actual repetition of the PUSCH[6, TS38.214] or PRACH transmission within the pre-configured time unit.

[0150] Assume that the time corresponding to the last symbol of the CORESET to which the DCI detected by the terminal is k. If the first symbol of the pre-configured SRS is between k and k+T proc,2 During this time period, the terminal does not cancel the signal from the first SRS symbol to k+T proc,2 The transmission in this time period is canceled instead of k+T proc,2 Subsequent SRS transmission.

[0151] Among them, T proc,2 It is the PUSCH preparation time under the terminal capability. Specifically, under the assumption that d 2,1=1, and μ corresponds to the SCS corresponding to the PDCCH that schedules PUCCH, PUSCH or SRS and the SCS or μ corresponding to the scheduled PUCCH, PUSCH or SRS information r Among them, when the subcarrier spacing of PRACH is not less than 15kHz, μ r is the SCS corresponding to PRACH, otherwise μ r =0.

[0152] In some embodiments, the collision between the SSB and uplink transmission (including semi-static pre-configured uplink transmission and dynamically scheduled uplink transmission) includes the following:

[0153] This type of collision also occurs in NR TDD systems. Consider reusing the same approach used in NR TDD. Specifically, prioritize SSB transmission over pre-configured uplink transmissions. For dynamically scheduled uplink transmissions, if an uplink transmission collides with an SSB, the uplink transmission is discarded and the SSB is prioritized.

[0154] In some embodiments, the collision between a valid RO / Msg.A PUSCH and downlink reception (including semi-statically pre-configured downlink reception and dynamically scheduled downlink reception, SSB) includes the following:

[0155] Valid ROs include PRACH resources in 4-step RACH and Msg.A PRACH resources in 2-step RACH. A terminal does not always need to perform random access; it is usually initiated by a certain event. Therefore, establishing a fixed rule to constrain transmission would actually hinder transmission flexibility. Therefore, this type of collision can be resolved by the terminal.

[0156] In some embodiments, Figure 1B is a schematic diagram illustrating a TA according to an embodiment of the present disclosure. As shown in Figure 1B , in an NTN scenario, the TA of a terminal changes rapidly due to the rapid movement of satellites. However, the TA information used by the terminal may not match the TA information known to the base station, which may affect the uplink and downlink transmission of HD-FDD terminals.

[0157] When an HD-FDD terminal supports repetition-based transmission on multiple slots, a TA mismatch when calculating the available slots can cause the base station to be unable to determine the specific location of the terminal's transmission, resulting in transmission failure.

[0158] It should be explained here that repetition in this application refers to the number of repetitions of the transmission. For example, when transmitting PUSCH and PUCCH, the repetition factor / number of repetitions / number of transmission time slots can be configured through RCC or DCI, that is, how many times the transmission is repeated. PUSCH repetition has two types: repetition type A and repetition type B. Among them, repetition type B cannot be transmitted on invalid symbols. That is to say, the terminal is not allowed to send uplink information on invalid symbols in the repetition type B transmission mode.

[0159] In view of this, the embodiments of the present disclosure propose a communication method, terminal, network device, communication system, storage medium and computer program product, which can effectively solve the problem of calculating invalid symbols when the TA information used by the terminal may not match the TA information of the terminal known by the base station when supporting PUSCH repetition type B, solve the problem of uplink and downlink transmission collision of HD-FDD terminals based on satellite communication systems, and ensure the validity of data transmission.

[0160] FIG2A is an interactive diagram illustrating a communication method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system 100. As shown in FIG2A , the method may include:

[0161] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0162] In some embodiments, the terminal 101 receives the first information. Optionally, the terminal 101 meets at least one of the following conditions:

[0163] Support receiving configuration information sent by network device 102;

[0164] Supports transmission mode based on physical uplink shared channel repetition type B (PUSCH repetition type B);

[0165] Support access to non-terrestrial network NTN;

[0166] Supports half-duplex frequency division duplex HD-FDD.

[0167] In some embodiments, the first information is used to determine a conflict resolution rule.

[0168] In some embodiments, the name of the first information is not limited, and it can be, for example, a conflict resolution strategy, a conflict resolution configuration, a target rule, etc.

[0169] In some embodiments, the network device may send the first information to the terminal via at least one message selected from the group consisting of physical layer signaling, media access control (MAC) layer signaling, and radio resource control (RRC) signaling.

[0170] In some embodiments, step S2101 may be omitted. The terminal determines the first information according to a protocol specification, that is, the first information may be specified by the protocol.

[0171] In some embodiments, step S2101 may be omitted. The terminal obtains the first information locally, that is, the first information may be information pre-stored on the terminal.

[0172] Step S2102 , the terminal 101 sends second information to the network device 102 .

[0173] In some embodiments, network device 102 receives second information.

[0174] In some embodiments, the second information is used to indicate the TA information of the terminal. Optionally, the time granularity of the TA information is configured by the network device. Optionally, the time granularity can be at the symbol level.

[0175] In some embodiments, the second information is used to assist the network device in acquiring timing information of the terminal.

[0176] In some embodiments, the second information is used to assist the network device in aligning time with the terminal.

[0177] In some embodiments, the name of the second information is not limited, and it can be, for example, delay information, error information, etc.

[0178] Step S2103 , the network device 102 sends third information to the terminal 101 .

[0179] In some embodiments, terminal 101 receives third information.

[0180] In some embodiments, the third information is used to indicate whether the terminal is allowed to use the first function. Optionally, the first function is a function for determining whether there is an invalid period within the first time period. Optionally, the third information is used to indicate whether the terminal is allowed to use the first function. Optionally, the third information is used to indicate whether the terminal is not allowed to use the first function.

[0181] In some embodiments, the invalid period corresponds to a time domain position that cannot be used for uplink transmission, and its name is not limited, and its name is, for example, an invalid symbol, an invalid time slot, etc.

[0182] In some embodiments, the first time period is one time unit, or the first time period is a plurality of consecutive time units, or the first time period is a plurality of non-consecutive time units.

[0183] In some embodiments, the name of the third information is not limited, and it can be, for example, a start / stop instruction for the first function.

[0184] In some embodiments, the terminal 101 receives the third information sent by the network device before determining whether there is an invalid period within the first period.

[0185] In some embodiments, the network device may send the third message to the terminal via at least one of physical layer signaling, media access control MAC layer signaling, and radio resource control RRC signaling.

[0186] In some embodiments, the third message is a physical layer control instruction or a high-layer configuration signaling. For example, if a predefined or preconfigured information field in the control instruction carries 1 bit of indication information, a value of "1" in the 1 bit of indication information may indicate that the terminal is to use the first function; a value of "0" in the 1 bit of indication information may indicate that the terminal is not to use the first function.

[0187] In some embodiments, when the terminal determines, based on the third information, that the network device allows the terminal to use the first function, it may determine whether there is an invalid period within the first period. The first period is a period during which the network device schedules the terminal to send information, and the invalid period is a period during which the terminal cannot send information. Sending information may refer to sending uplink information, for example, the terminal sending uplink information to the network device.

[0188] In some embodiments, the triggering event for triggering the terminal to determine whether an invalid period exists within the first period may be detecting a conflict between the first period and a second period. The second period is a period during which the terminal determines it needs to receive information, or the second period is a period during which the network device sends information to the terminal. Optionally, the terminal may determine the second period based on a downlink timeslot configuration for the network device to schedule the terminal to receive information.

[0189] The conflict refers to the overlap between the time period for sending information and the time period for receiving information, and the overlap is the conflict period. It should be noted that in the embodiment of the present disclosure, "conflict" can also be referred to as "collision" or "overlap".

[0190] In some embodiments, if it is determined that the first time period conflicts with the second time period, an invalid time period may exist within the first time period. Therefore, the terminal may further determine whether an invalid time period exists within the first time period.

[0191] In some embodiments, the second time period is one time unit, or the second time period is a plurality of consecutive time units, or the second time period is a plurality of non-consecutive time units.

[0192] In some embodiments, if the terminal needs to determine whether there is an invalid period within the first period, step S2104 may be executed.

[0193] In some embodiments, step S2103 may be omitted, and the terminal can use the first function by default. In the case that the terminal can use the first function by default, step S2104 may be performed.

[0194] In step S2104 , the terminal 101 determines a third time period according to the intersection of the first time period and the second time period.

[0195] In some embodiments, the third time period is an overlapping time period of the first time period and the second time period. The name of the third time period is not limited, and it is, for example, a conflicting time period.

[0196] In some embodiments, the third time period is one time unit, or the third time period is a plurality of consecutive time units, or the third time period is a plurality of non-consecutive time units.

[0197] In some embodiments, since the terminal needs to both send and receive information during the third time period, to avoid uplink and downlink conflicts, it can be determined based on the first information representing the conflict resolution rule whether the third time period is an invalid time period during which the terminal cannot send information.

[0198] In some embodiments, if the first time period and the second time period do not overlap, the first time period is determined as a valid time period. Steps S2105 to S2109 are omitted.

[0199] In step S2105 , the terminal 101 determines the time periods in the first time period except the third time period as valid time periods.

[0200] In some embodiments, the valid period is a period during which the terminal can send information, or the valid period is a time domain unit position that can be used for uplink transmission, and its name is not limited, and its name is, for example, uplink time slot, uplink symbol, etc.

[0201] In some embodiments, the time periods other than the third time period in the first time period may be referred to as non-conflict time periods. Since no uplink or downlink conflicts occur during non-conflict time periods, the non-conflict time periods may be directly determined as valid time periods. That is, the time periods other than the third time period in the first time period may be determined as valid time periods.

[0202] In some embodiments, the third time period is a portion or the entire time period of the first time period.

[0203] In some embodiments, when the third time period is equal to the first time period, step S2105 is omitted.

[0204] After step S2104 or step S2105, any one of steps S2106 to S2109 is executed.

[0205] Step S2106: The terminal 101 determines, based on the first information, that the terminal sends information in the third time period, and determines the third time period as a valid time period.

[0206] In some embodiments, if the first information indicates that the terminal may preferentially send information during the conflict period, the third period may be determined as a valid period.

[0207] Step S2107: The terminal 101 determines, based on the first information, that the terminal receives information in a third time period, and determines the third time period as an invalid time period.

[0208] In some embodiments, if the first information indicates that the terminal may receive information with priority over the conflicting period, the third period may be determined as an invalid period.

[0209] Step S2108: The terminal 101 determines, based on the first information, that the terminal receives information in a fourth time period in the third time period, and determines the fourth time period as an invalid time period.

[0210] In some embodiments, the fourth time period is one time unit, or the fourth time period is a plurality of consecutive time units, or the fourth time period is a plurality of non-consecutive time units.

[0211] In some embodiments, if the first information indicates that, during the conflict period, the priority of receiving designated information is higher than the priority of sending information, and the priority of sending information is higher than the priority of receiving non-designated information, then the terminal may determine whether there is a fourth period in the third period, where the fourth period is the period for receiving the designated information. If the fourth period exists, the fourth period is determined as an invalid period. Optionally, a fifth period in the third period, excluding the fourth period, is determined as a valid period.

[0212] In some embodiments, the fifth time period is one time unit, or the fifth time period is a plurality of consecutive time units, or the fifth time period is a plurality of non-consecutive time units.

[0213] In some embodiments, the designated information includes but is not limited to synchronization signal blocks SSB.

[0214] Step S2109: The terminal 101 determines, based on the first information, that the terminal sends information in the fifth time period in the third time period, and determines the fifth time period as a valid time period.

[0215] In some embodiments, if the first information indicates that, during the conflict period, the priority of receiving designated information is higher than the priority of sending information, and the priority of sending information is higher than the priority of receiving non-designated information, then the terminal may determine whether there is a fifth period in the third period, where the fifth period is a period in the third period during which the network device sends non-designated information. If the fifth period exists, the fifth period is determined as a valid period. Optionally, a fourth period in the third period other than the fifth period is determined as an invalid period.

[0388] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0389] In some embodiments, the terminal determines that PUSCH repetition type B is supported and accesses the NTN network.

[0390] In some embodiments, the terminal reports TA information, and the terminal determines the time granularity information of the TA information reporting based on the configuration of the base station. The time granularity of the TA information reporting may be symbol level.

[0391] In some embodiments, the terminal determines a time domain unit location that is unavailable for uplink transmission (invalid symbol) based on the following embodiments:

[0392] Embodiment 1: The time domain unit positions available for uplink transmission and the time domain unit positions unavailable for uplink transmission are determined based on a predefined or preconfigured conflict resolution rule.

[0393] Optionally, the terminal determines, based on a predefined or preconfigured conflict resolution rule, when an uplink and downlink transmission collision occurs, the time domain unit position that is not available for uplink transmission and the time domain unit position that is available for uplink transmission based on the conflict resolution rule.

[0394] Optionally, the terminal determines the conflict resolution rule based on a predefined method or by receiving high-layer signaling such as RRC, MAC CE or physical layer signaling sent by the base station: when an uplink or downlink conflict occurs, the terminal abandons downlink reception and always performs uplink transmission.

[0395] For example, referring to Figure 6A, when the terminal receives a scheduling instruction to determine that uplink transmission needs to be performed on three symbols, if it is determined that some of the three scheduled uplink symbols conflict with the downlink transmission reception, then the terminal abandons the reception of the downlink transmission based on a predefined conflict resolution rule and determines the three symbols as symbol positions that can be used for uplink transmission.

[0396] Optionally, the terminal determines a conflict resolution rule based on a predefined method or by receiving higher-layer signaling sent by the base station, such as RRC, MAC CE, or physical layer signaling: when an uplink / downlink conflict occurs, the terminal receives the target downlink signaling, thereby determining the position of the symbol that can be used for uplink transmission and the position of the symbol that cannot be used for uplink transmission. The target downlink signaling may be an SSB.

[0397] For example, referring to Figure 6B, when the terminal determines that it needs to perform uplink transmission on 4 symbols based on the received scheduling instruction, and determines that some of the 4 scheduled uplink symbols conflict with the downlink SSB reception, then the terminal receives the SSB based on predefined rules, that is, determines the symbol of the received SSB (the symbol where X is located in Figure 6B) as the symbol position that cannot be used for uplink transmission, and determines the remaining symbols as symbol positions that can be used for uplink transmission.

[0398] Optionally, the terminal determines the conflict resolution rule based on a predefined method or by receiving high-layer signaling such as RRC, MAC CE or physical layer signaling sent by the base station: when an uplink or downlink conflict occurs, the terminal always performs downlink reception, that is, all these conflicting symbols are determined as symbol positions that cannot be used for uplink transmission.

[0399] For example, referring to Figure 6C, when the terminal determines that it needs to perform uplink transmission on three symbols based on the received scheduling instruction, and determines that some of the three scheduled uplink symbols conflict with the downlink transmission reception, then the terminal abandons the uplink transmission on these certain symbols based on predefined rules, determines these certain symbols (i.e., the symbol where X is located in Figure 6C) as symbol positions that cannot be used for uplink transmission, and determines the remaining symbols as symbol positions that can be used for uplink transmission.

[0400] Embodiment 2: Determine whether to determine the available time domain resource location based on a scheduling indication or a higher layer signaling configuration.

[0401] Optionally, the terminal receives a physical layer scheduling instruction or a high-layer signaling configuration from the base station to determine whether to determine unavailable time domain resource information.

[0402] Optionally, the target control instruction instructs the terminal whether to use a function for determining unusable symbol positions (e.g., an invalid symbol determination function). For example, a 1-bit indication information is carried on an information field predefined or preconfigured in the target control instruction. If the value of the 1-bit indication information is "1," it may indicate that the invalid symbol determination function is enabled. If the value of the 1-bit indication information is "0," it indicates that the invalid symbol determination function is not enabled. Based on the indication information in the target control instruction, the terminal may determine whether to determine a resource location that is unavailable for uplink transmission.
