[0142] In some embodiments of the present disclosure, the continuous emergence of new Internet applications such as augmented reality (AR) / virtual reality (VR) and vehicle-to-vehicle communications has placed higher demands on wireless communication technology, driving the continuous evolution of wireless communication technology to meet application needs. Currently, cellular mobile communication technology is in the evolution stage of the next generation of technology. A key feature of the next generation of technology is the flexible configuration that supports multiple service types. Because different service types have different requirements for wireless communication technology, such as the enhanced Mobile Broadband (eMBB) service type mainly focuses on large bandwidth and high speed; the ultra-reliable low-latency communication (URLLC) service type mainly focuses on high reliability and low latency; and the enhanced machine type communication (mMTC) service type mainly 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.
[0143] In the study of wireless communication technology, satellite communication is considered an important aspect of future wireless communication technology development. Satellite communication refers to communication conducted by ground-based radio communication equipment using satellites as relays. Satellite communication systems consist of satellite and ground components. Satellite communication features include: a wide communication range; communication between any two points within the coverage area of the satellite's radio waves; and low susceptibility to land-based disasters (high reliability). As a supplement to current ground-based cellular communication systems, satellite communication can provide the following benefits:
[0144] (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.
[0145] (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.
[0146] (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.
[0147] 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.
[0148] In some embodiments, in a satellite communication system, a scenario in which a terminal type with reduced capability (RedCap) operating in HD-FDD accesses an NTN network can be supported.
[0149] 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.
[0150] 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:
[0151] (1) Collision between dynamically scheduled transmissions and semi-statically preconfigured transmissions on the same time unit;
[0152] (2) collisions between dynamically scheduled transmissions / receptions and dynamically scheduled receptions / transmissions on the same time unit;
[0153] (3) Collision between semi-static preconfigured transmission / reception and semi-static preconfigured reception / transmission in the same time unit;
[0154] (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;
[0155] (5) Collision between valid RO / Msg.A PUSCH (Physical Uplink Shared Channel) and downlink reception (including semi-statically pre-configured downlink reception and dynamically scheduled downlink reception) in the same time unit.
[0156] 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 Physical Downlink Control Channel (PDCCH) (type 0 / 0A / 1 / 2CSS), PDSCH, CSI-RS or Downlink Positioning Reference Signal (DL PRS), while the uplink transmission includes the pre-configured PUSCH, PUCCH and SRS.
[0157] In some embodiments, collisions between dynamically scheduled transmit / receive and dynamically scheduled receive / transmit include the following:
[0158] 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.
[0159] In some embodiments, the collision between semi-static pre-configured transmission / reception and semi-static pre-configured reception / transmission includes the following:
[0160] 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.
[0161] In some embodiments, collisions between dynamically scheduled transmissions and semi-statically preconfigured transmissions include the following:
[0162] 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.
[0163] 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.
[0164] 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.
[0165] 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 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.
[0166] 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.
[0167] 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 rAmong them, when the subcarrier spacing of PRACH is not less than 15kHz, μ r is the SCS corresponding to PRACH, otherwise μ r =0.
[0168] 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:
[0169] 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.
[0170] 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:
[0171] 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.
[0172] 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.
[0173] 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.
[0174] 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. As shown in FIG2A , the method may include:
[0175] Step S2101: The network device sends second information to the terminal device.
[0176] In some embodiments, the terminal device may receive the second information. For example, the terminal device may receive the second information sent by the network device. For another example, the terminal device may also receive the second information sent by another entity.
[0177] In some embodiments, the terminal device may satisfy at least one of the following:
[0178] The uplink transmission or downlink transmission to be performed needs to be carried on multiple transmission units;
[0179] Access to non-terrestrial network NTN;
[0180] Supports half-duplex frequency division multiplexing HD-FDD.
[0181] In some embodiments, the second information may be used to pre-configure the first information.
[0182] In some embodiments, the network device may send the second information to the terminal device via the first signaling.
[0183] In some embodiments, the first signaling may include at least one of the following: RRC signaling, Media Access Control Control Element (MAC CE), and physical layer signaling.
[0184] It should be noted that the above-mentioned first signaling is an exemplary description and is not limited to this embodiment of the present disclosure.
[0185] In some embodiments, the name of the second information is not limited, and may be, for example, "rule configuration information", "rule configuration indication information", etc.
[0186] In some embodiments, the first information may be used to determine conflict resolution rules.
[0187] In some embodiments, the conflict resolution rule may include receiving downlink information of a downlink transmission bearer, or giving up receiving downlink information of a downlink transmission bearer.
[0188] In some embodiments, “receiving downlink information carried by a downlink transmission” may be understood as receiving the downlink information carried by the downlink transmission and abandoning sending the uplink information carried by the uplink transmission when an uplink transmission collides with a downlink transmission.
[0189] In some embodiments, “giving up sending uplink information carried by uplink transmission” may be understood as the transmission unit giving up sending uplink information carried by uplink transmission when uplink transmission collides with downlink transmission.
[0190] In some embodiments, “giving up receiving downlink information carried by downlink transmission” can be understood as giving up receiving downlink information carried by downlink transmission and sending uplink information carried by uplink transmission when uplink transmission collides with downlink transmission.
[0191] In some embodiments, the name of the first information is not limited, and may be, for example, "conflict resolution rule information", "rule information", etc.
[0192] In some embodiments, the name of the conflict resolution rule is not limited, and may be, for example, "conflict resolution strategy", "conflict resolution method", "conflict handling strategy", etc.
[0193] In some embodiments, after receiving the second information sent by the network device, the terminal device can pre-configure the first information according to the second information, that is, pre-configure the conflict resolution rule.
[0194] Step S2102: The terminal device determines that an uplink transmission collides with a downlink transmission.
[0195] In some embodiments, the uplink transmission may be used to carry uplink information, and the downlink transmission may be used to carry downlink information.
[0196] In some embodiments, the uplink transmission may be understood as an uplink channel, such as PUSCH and PUCCH. The uplink information may be, for example, uplink control information (UCI) carried by the PUSCH.
[0197] In some embodiments, the downlink transmission may be understood as a downlink channel, such as a PDSCH or a PDCCH. The downlink information may be, for example, a DCI carried by the PDCCH.
[0198] In some embodiments, when the terminal device determines that uplink transmission and downlink transmission need to be performed simultaneously, it can be determined that the uplink transmission and the downlink transmission collide.
[0199] In some embodiments, it is determined that a conflict exists between the first transmission unit and the second transmission unit, and it is determined that an uplink transmission collides with a downlink transmission.
[0200] In some embodiments, the first transmission unit may include a transmission unit for sending uplink information of an uplink transmission bearer, and the second transmission unit may include a transmission unit for receiving downlink information of a downlink transmission bearer.
[0201] In some embodiments, the transmission unit may be a time slot, which is not limited in the embodiments of the present disclosure.
[0202] Taking the transmission unit as an example of a time slot, Figure 2B is a schematic diagram of a transmission unit according to an embodiment of the present disclosure. As shown in Figure 2B, the first transmission unit may include three time slots, and the second transmission unit may include one time slot. Among the three time slots for uplink transmission to be scheduled, the second time slot conflicts with the time slot for downlink transmission, and it can be determined that the uplink transmission and the downlink transmission have collided.
[0203] It should be noted that, in the embodiments of the present disclosure, "collision" may also be referred to as "conflict."
[0204] Step S2103: The terminal device determines the transmission unit for uplink transmission based on the first information.
[0205] In some embodiments, the transmission unit may be a time slot for uplink transmission.
[0206] In some embodiments, it is determined based on the first information that the downlink information carried by the downlink transmission is abandoned, and the first transmission unit is used as the transmission unit for uplink transmission.
[0207] In some embodiments, “using the first transmission unit as a transmission unit for uplink transmission” may be understood as performing uplink transmission according to the transmission unit originally scheduled for uplink transmission.
[0208] In some embodiments, if it is determined to abandon receiving the downlink information carried by the downlink transmission, only uplink transmission is performed in the conflicting transmission unit.
[0209] Continuing with FIG2B as an example, for the first transmission unit, the conflicting transmission unit is the second time slot. If only uplink transmission is performed in the conflicting time slot, downlink transmission will not affect uplink transmission, and the terminal device can continue to perform uplink transmission according to the first transmission unit.
[0210] In some embodiments, downlink information of the downlink transmission bearer is determined to be received according to the first information, a fourth transmission unit is determined from the third transmission unit, and the fourth transmission unit is used as a transmission unit for uplink transmission.
[0211] In some embodiments, the third transmission unit may include a transmission unit other than the second transmission unit.
[0212] In some embodiments, if the terminal device determines that the conflict resolution rule is to receive downlink information carried by downlink transmissions, then no uplink transmission will be performed when an uplink transmission collides with a downlink transmission. In other words, only downlink transmission will be performed on the conflicting transmission unit. In this case, the uplink transmission required on the conflicting transmission unit can be delayed.
[0213] Figure 2C is a schematic diagram of a transmission unit according to an embodiment of the present disclosure. As shown in Figure 2C, the time slot corresponding to "X" is a collision time slot, and the third transmission unit may include time slots other than the collision time slot. The terminal device only performs downlink transmission in the collision time slot and uses the one time slot adjacent to the collision time slot before the collision time slot and the two time slots adjacent to the collision time slot after the collision time slot as the fourth transmission unit for uplink transmission.
[0214] It should be noted that the above method of determining the fourth transmission unit from the third transmission unit is for illustration only and is not limited in the embodiments of the present disclosure.
[0215] By adopting the above method, when uplink transmission collides with downlink transmission, the transmission unit of uplink transmission can be re-determined according to the pre-configured conflict resolution rule to resolve the impact of the uplink and downlink collision on uplink transmission and ensure the effectiveness of data transmission.

[0218] In some embodiments, the above steps S2101 to S2103 are all optional steps.

[0231] In some embodiments, the third information may be 1-bit indication information carried on the second signaling, wherein "1" indicates support for calculation of available transmission units and "0" indicates non-support for calculation of available transmission units.

[0236] In some embodiments, if the terminal device determines that an uplink transmission collides with a downlink transmission, it may determine whether calculation of available transmission units is supported based on the third information. For example, if the bit indicated by the third information is "1," it may be determined that calculation of available transmission units is supported; if the bit indicated by the third information is "0," it may be determined that calculation of available transmission units is not supported.
[0237] In some embodiments, if it is determined that the calculation of available transmission units is not supported, step S2405 is not performed, and the collision between the uplink transmission and the downlink transmission can be handled by a method in an existing protocol.
[0238] It should be noted that step S2404 may be executed before step S2403 or after step S2403, and this embodiment of the present disclosure does not limit this.
[0239] Step S2405: The terminal device determines the transmission unit for uplink transmission based on the first information.
[0240] The optional implementation of step S2405 can refer to the optional implementation of step S2103 in FIG2A and other related parts in the embodiment involved in FIG2A , which will not be described in detail here.

[0343] The optional implementation of step S4301 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.
[0344] In some embodiments, the second information is used to pre-configure the first information, the first information is used to determine a conflict resolution rule, and the first information is used by the terminal device to determine the transmission unit of the uplink transmission when determining that the uplink transmission collides with the downlink transmission.
[0345] In some embodiments, the conflict resolution rule includes receiving downlink information of the downlink transmission bearer, or giving up receiving downlink information of the downlink transmission bearer.
[0346] In some embodiments, sending the second information to the terminal device includes:
[0347] The second information is sent to the terminal device via a first signaling, where the first signaling includes at least one of the following: radio resource control RRC signaling, media access control layer control signaling MAC CE, and physical layer signaling.

[0349] Third information is sent to the terminal device, where the third information is used to indicate whether calculation of available transmission units is supported.
[0350] In some embodiments, the third information is used by the terminal device to determine the transmission unit for the uplink transmission based on the first information when determining to support calculation of available transmission units.
[0351] In some embodiments, sending the third information to the terminal device includes:
[0352] The third information is sent to the terminal device via second signaling, where the second signaling includes at least one of the following: RRC signaling, MAC CE, and physical layer signaling.
[0353] In some embodiments, the terminal device satisfies at least one of the following:
[0354] The uplink transmission or the downlink transmission to be performed needs to be carried on multiple transmission units;
[0355] Access to non-terrestrial network NTN;
[0356] Supports half-duplex frequency division multiplexing HD-FDD.
[0357] In some embodiments, the terminal determines that a transmission needs to be carried on multiple slots based on an indication of the DCI or a configuration of a higher-layer signaling; and the terminal determines to access the NTN network.
[0358] In some embodiments, the terminal may base the conflict resolution on predefined or configured rules.
[0359] Wherein, when the terminal determines that an uplink and downlink transmission collision occurs based on a predefined or preconfigured rule, the terminal determines a time domain unit position of the uplink transmission based on the target rule.
[0360] In one implementation, the terminal determines a rule based on a predefined method or by receiving high-layer signaling sent by the base station, such as RRC, MACCE, or physical layer signaling. The rule may be: in the event of an uplink / downlink conflict, the terminal abandons downlink reception and always performs uplink transmission. As shown in FIG2B , when the terminal receives a scheduling instruction to determine that uplink transmission needs to be performed on three slots, and determines that a slot in the scheduled uplink slots conflicts with downlink SSB reception, the terminal abandons reception of the SSB transmission based on the predefined rule and determines the slot position of the scheduled uplink transmission.
[0361] In another implementation, the terminal determines a rule based on a predefined method or by receiving high-layer signaling such as RRC, MACCE, or physical layer signaling sent by the base station. The rule may be: in the event of an uplink or downlink conflict, the terminal performs reception of the target downlink signaling and determines the position of the slot used for uplink transmission. The target downlink signaling may be SSB or other downlink signaling. As shown in Figure 2C, when the terminal receives a scheduling instruction to determine that uplink transmission needs to be performed on three slots, and determines that a slot in the scheduled uplink slot conflicts with the downlink SSB reception, the terminal receives the SSB based on the predefined rule and determines the slot position of the scheduled downlink transmission.
[0362] In some embodiments, the available time domain resource location may be determined based on a scheduling indication or a higher layer signaling configuration.
[0363] The terminal receives a physical layer scheduling instruction from the base station or a high-layer signaling configuration to determine available time domain resource information.
[0364] In one implementation, support for available slot counting is determined via a target control instruction. For example, a "1" bit of indication information may be included in a predefined or preconfigured information field within the target control instruction. A "1" bit may indicate that available slot counting is enabled, while a "0" bit may indicate that available slot counting is disabled. Based on the indication in the target control instruction, the terminal determines the resource location for uplink transmission.
[0365] In another implementation, whether the available slot counting function is supported may be indicated by high-level configuration signaling, and the terminal determines the resource location for uplink transmission based on the indication in the target high-level instruction.
[0366] In some embodiments, the terminal may determine the available slot based on a traditional collision avoidance method, and the base station needs to detect possible uplink transmission positions at multiple locations.
[0367] By using the above method, when the TA information used by the terminal may not match the TA information of the terminal known by the base station, the problem of uplink and downlink conflict is solved, thereby ensuring the effectiveness of data transmission.
[0368] In some embodiments of the present disclosure, a communication system is provided, which may include a terminal device and a network device, wherein the terminal device can execute the communication method executed by the terminal device in the aforementioned embodiment of the present disclosure; the network device can execute the communication method executed by the network device in the aforementioned embodiment of the present disclosure.
