[0028] The embodiments of the present application will be described below in conjunction with the accompanying drawings. The present application will be described below in conjunction with the accompanying drawings of the embodiments. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0029] Figure 1 is a schematic diagram of an implementation of an NTN architecture provided by the prior art. As Figure 1 shown, in the NTN communication system, the link between the UE and the satellite is the service link, and the link between the access network device (such as a base station, a gateway station) and the satellite is the feeder link, and for all UEs (such as Figure 1 the UE1 and UEx shown) in the same cell, it is common.

[0030] In NTN, the UE can perform TA pre-compensation according to information such as satellite position, its own position, and common TA. Since the position of the UE is usually unknown at the network node, the network node may not know the TA value at the UE. To help the network node perform better scheduling, the UE can report the TA value in units of time slots; however, after the base station receives the reported TA value, due to the existence of large transmission delays and the rapid movement of the satellite and the UE, there is a large deviation between the TA recognized by the base station side and the TA actually measured or applied by the UE side.

[0031] For HD-FDD and TDD UEs, currently, due to TA mismatch, the following resource collision / overlap problems may occur:

[0032] Case 1: The reception of the dynamically scheduled downlink (DL) signal collides / overlaps with the transmission of the semi-statically configured uplink (UL) signal;

[0033] Case 2: The reception of the semi-statically configured DL signal collides / overlaps with the transmission of the dynamically scheduled UL signal;

[0034] Case 3: The reception of the semi-statically configured DL signal collides / overlaps with the transmission of the semi-statically configured UL signal;

[0035] Case 4: The reception of the dynamically scheduled DL signal collides / overlaps with the transmission of the dynamically scheduled UL signal;

[0036] Case 5: The configured SSB collides / overlaps with the transmission of the dynamically scheduled / semi-statically configured UL signal;

[0037] Case 6: The dynamic or semi-static downlink signal collides / overlaps with the valid random access opportunity (RO).

[0038] The dynamic scheduling in each of the above cases refers to the network (such as a base station, satellite, relay node, etc.) sending downlink control information (DCI) to schedule or instruct the UE to receive DL signals or send UL signals (for example, the DL signal can be a physical downlink shared channel (PDSCH) (such as a system information block (SIB19)), or a channel state information reference signal (CSI-RS), and the UL signal can be a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a physical random access channel (PRACH) / the first random access message (MsgA), or a sounding reference signal (SRS)). The semi-static configuration means that the network configures the UE to receive DL signals or send UL signals through high-layer parameters (for example, the DL signal can be a physical downlink control channel (PDCCH), PDSCH, a synchronization signal broadcast channel block (SSB), CSI-RS, or a downlink positioning reference signal (DL-PRS), and the UL signal can be PUCCH, PUSCH, or SRS).

[0039] The collision / overlap in each of the above cases includes: two types of signals (such as DL signal reception and UL signal transmission) collide due to time-frequency resource overlap, and / or, although the time-frequency resources of the two types of signals do not overlap, but because there is not enough uplink-downlink switching time between them, a collision occurs. For example, after DL reception, at least N Rx-Tx ·T c intervals must be left to avoid collision; after UL transmission, at least N Tx-Rx ·T c intervals must be left to avoid collision. T c is the basic time unit of the access technology, and N Rx-Tx 、N Tx-RxThey are the number of basic time units required to switch from reception to transmission and from transmission to reception, respectively.

[0040] For Case 1, Case 2, Case 5, and Case 6, to solve the resource collision / overlap problem caused by TA mismatch, the solutions of the RedCap UE and its corresponding network for the same case can be reused.

[0041] For Case 3 and Case 4, the existing rules identify these two cases as incorrect use cases. That is, the UE does not expect to perform semi-statically configured DL reception and semi-statically configured UL transmission simultaneously, or does not expect to perform dynamically scheduled DL reception and dynamically scheduled UL transmission simultaneously. Correspondingly, the network side will not configure or schedule in this way. However, in NTN communication, due to the large transmission delay, there is a large error between the timing determined by the network side and the actual timing of the UE side. Even if the network configures and instructs according to the above behavior, the problem of collision / overlap between semi-statically configured DL reception and semi-statically configured UL transmission, or collision / overlap between dynamically scheduled DL reception and dynamically scheduled UL transmission may still occur on the UE side.

[0042] In one embodiment, Figure 2 is a flowchart of a signal transmission method provided by an embodiment of this application. This embodiment is applied to the situation of overlapping or colliding uplink and downlink signal transmission resources in the NTN scenario. This embodiment can be executed by a first communication node. Exemplarily, the first communication node can be the terminal side. For example, the terminal side can include, but is not limited to, one of the following: User Equipment (UE). As Figure 2 shown, this embodiment includes: S210 - S220.

[0043] S210. Determine the transmission priority information.

[0044] In one example, the transmission priority information can be indicated by the second communication node or directly pre-configured. In one example, when the transmission priority information is indicated by the second communication node, the first communication node can receive the transmission priority information configured or indicated by the second communication node. In one example, when the transmission priority information is directly pre-configured, the first communication node can directly obtain the transmission priority information, that is, the priority of one signal can be directly configured to be higher than that of another signal. Exemplarily, the priority of the first uplink signal (which can also be referred to as the first uplink signal, or the first UL signal) can be directly configured to be higher than the priority of the first downlink signal (which can also be referred to as the first downlink signal, or the first DL signal); or, the priority of other uplink signals (which can also be referred to as other uplink signals, or other UL signals) is lower than the priority of the first downlink signal; or, the priority of the first uplink signal is lower than the priority of the first downlink signal; the high or low priority of the first uplink signal and the first downlink signal is determined based on the UE implementation (which can also be simply referred to as UE implementation); or, the high or low priority of other uplink signals and the first downlink signal is determined based on the UE implementation.

[0045] In one example, the transmission priority information is used to characterize the high or low situation between the transmission priorities of the dynamically scheduled DL signal and the dynamically scheduled UL signal in the case where the dynamically scheduled DL signal and the dynamically scheduled UL signal collide or overlap. In one example, the transmission priority information is used to characterize the high or low situation between the transmission priorities of the semi-statically configured DL signal and the semi-statically configured UL signal in the case where the semi-statically configured DL signal and the semi-statically configured UL signal collide or overlap.

[0046] S220. Perform signal transmission according to the determined transmission priority information.

[0047] In the case where the resources of the DL signal and the UL signal collide or overlap, the first communication node can send the DL signal or the UL signal according to the pre-determined transmission priority information to be sent to the second communication node, solving the technical problem of uplink and downlink resource conflicts and effectively ensuring the transmission efficiency of uplink and downlink signals.

[0048] In one embodiment, determining the transmission priority information includes: determining the transmission priority information in the case where the transmission resources of the uplink signal and the downlink signal overlap or collide. In one example, the transmission priority information can be determined in the case where the transmission resources associated with the uplink signal and the transmission resources associated with the downlink signal overlap or collide. In one example, the transmission resources can include time domain resources.

In one example, the signals included in the first downlink signal and the signals included in the other downlink signals are mutually exclusive, that is, the signals included in both are completely non - overlapping. In one example, the signals included in the first uplink signal and the signals included in the other uplink signals are mutually exclusive, that is, the signals included in both are completely non - overlapping. In one example, both the first downlink signal and the other downlink signals may include one or more signals. In one example, both the first uplink signal and the other uplink signals may include one or more signals. In one example, the downlink signal may include: a dynamically scheduled downlink signal, or, a semi - statically configured downlink signal; correspondingly, the first downlink signal may include: a dynamically scheduled first downlink signal, or, a semi - statically configured first downlink signal; the other downlink signals may include: a dynamically scheduled other downlink signal, or, a semi - statically configured other downlink signal. In one example, the uplink signal may include: a dynamically scheduled uplink signal, or, a semi - statically configured uplink signal; correspondingly, the first uplink signal may include: a dynamically scheduled first uplink signal, or, a semi - statically configured first uplink signal; the other uplink signals may include: a dynamically scheduled other uplink signal, or, a semi - statically configured other uplink signal.

[0114] In one embodiment, in the case where at least one downlink transmission collides or overlaps with at least one uplink transmission, the resource collisions of each downlink transmission and uplink transmission are processed in chronological order.

[0115] In one embodiment, in the case where at least one downlink transmission collides or overlaps with at least one uplink transmission, it depends on the UE implementation;

[0116] Alternatively, in the case where the multiple transmissions with resource overlap include a first downlink signal and / or a first uplink signal, the downlink signal is determined to be received or the uplink signal is determined to be transmitted based on the UE implementation.

[0184] In the following embodiments, taking the first communication node as the UE and the second communication node as the network node (which can also be referred to as the network or network side) as an example, the signal transmission process in the case of resource collision or overlap between the uplink and downlink resources is described.

[0185] Embodiment 1

[0186] For the case where the reception of the dynamically scheduled DL signal collides / overlaps with the transmission of the dynamically scheduled UL signal:

[0187] For types of UEs such as HD-FDD or TDD, when the reception of the dynamically scheduled DL signal collides / overlaps with the transmission of the dynamically scheduled UL signal, the following solutions can be adopted:

[0188] The dynamically scheduled DL signals are divided into two categories: the first DL signal and other DL signals; the dynamically scheduled UL signals are divided into two categories: the first UL signal and other UL signals.

[0189] The importance of the first DL signal is different from that of other DL signals. For example, the PDSCH carrying system information is different from other DL signals. The importance of the first UL signal is different from that of other UL signals. For example, the PRACH or MsgA is different from other UL signals.

[0190] If the carried system information has been previously acquired by the UE, then the carried system information is not very important to the UE and the PDSCH priority is lower. However, if the carried system information has not been previously acquired by the UE, then the carried system information is very important to the UE and the PDSCH priority is higher. PRACH or MsgA is particularly important for uplink synchronization.

[0191] The dynamically scheduled DL signals include at least one of the following: PDSCH, CSI-RS.

[0192] The dynamically scheduled DL signals are divided into first DL signals and other DL signals.

[0193] Among them, the first DL signals include at least one of the following: PDSCH carrying specific information, CSI-RS for specific purposes. It is scheduled by the PDCCH configured by the common search space set (e.g., at least one of Type-0 / 0A-PDCCH CSS). The carried system information may include: system information such as SIB1 or SIB19. The CSI-RS for specific purposes may be the CSI-RS used for functions such as radio resource management (RRM) measurement, CSI measurement, beam management, or time-frequency tracking. Other DL signals include one or more signals other than the first DL signals in the DL signals.

[0194] The dynamically scheduled UL signals include at least one of the following: PUSCH, PUCCH, PRACH / MsgA, SRS.

[0195] The dynamically scheduled UL signals are divided into first UL signals and other UL signals.

[0196] Among them, the first UL signals include at least one of the following: PUSCH, PUCCH, PRACH / MsgA, SRS; other UL signals include one or more signals other than the first UL signals in the UL signals.

[0197] When the first UL signal is PRACH / MsgA, the other UL signals include at least one of the following: PUSCH, PUCCH, SRS.

[0198] When the first UL signal is PUCCH, the other UL signals include at least one of the following: PRACH / MsgA, PUSCH, SRS.

[0199] When the first UL signal is a PUCCH carrying specific information (such as HARQ-ACK, scheduling request SR, or CSI feedback), the other UL signals include at least one of the following: PRACH / MsgA, a PUCCH carrying other information (such as other information in HARQ-ACK / scheduling request SR / CSI feedback other than the above specific information), PUSCH, and SRS.

[0200] When the first UL signal is PRACH / MsgA and PUCCH, the other UL signals include at least one of the following: PUSCH and SRS.

[0201] And so on. When the first UL signal is one or more signals among {PUSCH, PUCCH, PRACH / MsgA, SRS}, the other UL signals are one or more signals among {PUSCH, PUCCH, PRACH / MsgA, SRS} other than the first UL signal.

[0202] The priority between transmitting UL signals with dynamic scheduling and receiving DL signals with dynamic scheduling can be divided into three types: depending on UE implementation, the former has a higher priority than the latter, and the former has a lower priority than the latter.

[0203] In this application, the priority of signal A (or the resource for transmitting signal A) being higher than the priority of signal B (or the resource for transmitting signal B) means that: when there is signal A on a certain resource, the UE does not receive or transmit signal B; or, when there is no signal A on a certain resource, the UE can only receive or transmit signal B on that resource. Or, when the resource for transmitting signal A overlaps / collides with the resource for transmitting signal B, the UE does not receive or transmit signal B; or, when the resource for transmitting signal B does not overlap / collide with the resource for transmitting signal A, the UE can receive or transmit signal B. The rules of priority here apply to each embodiment or example in this application.

[0204] For example, the priority of transmitting UL signal X being higher than the priority of receiving DL signal Y with dynamic scheduling is reflected in that: if the UE receives the first DCI sent by the network, which is used to instruct the UE to receive DL signal Y on the first resource (for example, some symbols), and if the UE does not receive the second DCI sent by the network, which is used to instruct the UE to transmit UL signal X on the first resource or at least / any part of the first resource (for example, one symbol), then the UE receives the DL signal Y. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not receive the DL signal Y.

[0205] For another example, the priority of transmitting the UL signal X being lower than that of receiving the dynamically scheduled DL signal Y is reflected in that: if the UE receives the first DCI sent by the network, which is used to instruct the UE to transmit the UL signal X on the first resource (e.g., some symbols), and if the UE does not receive the second DCI sent by the network, which is used to instruct the UE to receive the DL signal Y on the first resource or at least / any part of the first resource (e.g., one symbol), then the UE transmits the UL signal X. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not transmit the UL signal X.

[0206] In this application, when receiving the DL signal and transmitting the UL signal overlap / collide in time-frequency resources (e.g., on some symbols), not receiving the DL signal / not transmitting the UL signal includes two methods: Method 1) Completely cancel the reception / transmission of the signal with lower priority; Method 2) Only on the overlapping / colliding time-frequency resources (including the necessary handover / protection resources on both sides), do not receive / transmit the corresponding part of the signal with lower priority, and on the non-overlapping / non-colliding time-frequency resources, it is still possible to receive / transmit the other part of the signal with lower priority. For example, a part of the DL signal Y (assumed to be Y1) overlaps / collides with the UL signal X, and the DL signal Y is a signal with lower priority. In Method 1, the DL signal Y is not received at all; in Method 2, only this part of Y1 of the DL signal is not received, and the other parts are still received normally.

[0207] The scheme for the priority of transmitting the dynamically scheduled UL signal compared to receiving the first dynamically scheduled DL signal is shown in Table 1-1. The scheme for the priority of transmitting the dynamically scheduled UL signal compared to receiving other dynamically scheduled DL signals is shown in Table 1-2. Combining any one method in Table 1-1 with any one method in Table 1-2 is a complete solution to the overlap / collision between the dynamically scheduled UL signal and the DL signal.

[0220] Table 1-2: Priority of UL signals for transmitting dynamic scheduling compared to other DL signals for receiving dynamic scheduling

[0221]

[0222] As shown in Table 2-1, in the case where the UL signal (the first UL signal or other UL signals) overlaps or collides with other DL signals, one of the 9 methods, namely Method 1-2-1, Method 1-2-2, Method 1-2-3... Method 1-2-9, can be used to resolve the conflict.

[0223] Method 1-2-1: Determine the priority between the UL signal and other DL signals based on the UE implementation;

[0232] According to the combination of the methods in Table 1-1 and the methods in Table 1-2, some typical embodiment solutions for solving the overlap / collision between UL signals and DL signals in dynamic scheduling are given below.

[0233] Example 1: The first UL signal vs. all DL signals, other UL signals vs. all DL signals

[0234] The first DL signal and other DL signals in dynamic scheduling adopt the same priority rule, so the DL signals in dynamic scheduling can be regarded as a whole to consider the priority. The UL signals in dynamic scheduling are still divided into two categories to consider the priority: the first UL signal and other UL signals.

[0235] When Method 1-3-1 to Method 1-3-4 respectively determine that the first UL signal / other UL signals collide / overlap with the resources of the dynamically scheduled DL signal, the UE determines whether to send the first UL signal / other UL signals or receive the dynamically scheduled DL signal.

[0236] Table 1-3: Priority of Sending Dynamically Scheduled UL Signals Compared to Receiving Dynamically Scheduled DL Signals

[0237]

[0238] Method 1-3-1: Whether to send the first UL signal based on dynamic scheduling or receive the dynamically scheduled DL signal depends on the UE implementation; the priority of sending other dynamically scheduled UL signals is higher than the priority of receiving the dynamically scheduled DL signal.

[0239] Method 1-3-1 is composed of Method 1-1-3 and Method 1-2-3 in Table 1-1 / 2.

[0240] The fact that the priority of sending other UL signals is higher than the priority of receiving the dynamically scheduled DL signal is reflected in: If the UE receives the first DCI sent by the network, and this DCI is used to instruct the UE to receive the DL signal on the first resource (for example, some symbols) (corresponding to the above low-priority signal B), and if the UE does not receive the second DCI sent by the network, and this DCI is used to instruct the UE to send other UL signals on the first resource or at least / any part of the first resource (for example, one symbol) (corresponding to the above high-priority signal A), then the UE receives the DL signal. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not receive the DL signal.

[0241] Method 1-3-2: Whether to send the first UL signal based on dynamic scheduling or receive the dynamically scheduled DL signal depends on the UE implementation; the priority of sending other dynamically scheduled UL signals is lower than the priority of receiving the dynamically scheduled DL signal.

[0242] Method 1-3-2 is composed of Method 1-1-2 and Method 1-2-2 in Table 1-1 / 2.

[0243] The priority of transmitting other UL signals is lower than that of receiving dynamically scheduled DL signals, which is reflected in: If the UE receives the first DCI sent by the network, this DCI is used to instruct the UE to transmit other UL signals (corresponding to the above-mentioned low-priority signal B) on the first resource (e.g., some symbols), and if the UE does not receive the second DCI sent by the network, this DCI is used to instruct the UE to receive DL signals (corresponding to the above-mentioned high-priority signal A) on the first resource or at least / any part of the first resource (e.g., one symbol), then the UE transmits the said other UL signals. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not transmit the said other UL signals.

[0244] Method 1-3-3: The priority of transmitting the first UL signal based on dynamic scheduling is higher than that of receiving dynamically scheduled DL signals; the priority of transmitting other UL signals based on dynamic scheduling is lower than that of receiving dynamically scheduled DL signals, or whether to transmit other UL signals based on dynamic scheduling or receive dynamically scheduled DL signals depends on the UE implementation.

[0245] Method 1-3-3 is composed of Method 1-1-7 / 8 and Method 1-2-7 / 8 in Table 1-1 / 2.

[0246] The priority of transmitting the first UL signal based on dynamic scheduling is higher than that of receiving dynamically scheduled DL signals, which is reflected in: If the UE receives the first DCI sent by the network, this DCI is used to instruct the UE to receive DL signals (corresponding to the above-mentioned low-priority signal B) on the first resource (e.g., some symbols), and if the UE does not receive the second DCI sent by the network, this DCI is used to instruct the UE to transmit the first UL signal (corresponding to the above-mentioned high-priority signal A) on the first resource or at least / any part of the first resource (e.g., one symbol), then the UE receives the said DL signals. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not receive the said DL signals.

[0247] The priority of transmitting other UL signals is lower than that of receiving dynamically scheduled DL signals, which is the same as in Method 1-3-2.

[0248] Method 1-3-4: The priority of transmitting the first UL signal based on dynamic scheduling is lower than that of receiving dynamically scheduled DL signals; the priority of transmitting other UL signals based on dynamic scheduling is higher than that of receiving dynamically scheduled DL signals, or whether to transmit other UL signals based on dynamic scheduling or receive dynamically scheduled DL signals depends on the UE implementation.

[0249] Method 1-3-4 is composed of Method 1-1-6 / 4 and Method 1-2-6 / 4 in Table 1-1 / 2.

[0250] The first UL signal in Mode 1-3-4 is equivalent to the other UL signals in Mode 1-3-3 above, and the other UL signals are equivalent to the first UL signal in Mode 1-3-3 above.

[0251] Example 2: The first DL signal vs. all UL signals; other DL signals vs. all UL signals:

[0252] The first UL signal with dynamic scheduling and the other UL signals adopt the same priority rule. Therefore, the UL signals with dynamic scheduling can be regarded as a whole to consider the priority. The DL signals with dynamic scheduling are still divided into two categories to consider the priority: the first DL signal and the other DL signals.

[0253] Modes 1-4-1 to 1-4-4 respectively determine whether the UE receives the first DL signal / other DL signals or transmits the UL signal with dynamic scheduling when the first DL signal / other DL signals and the UL signal with dynamic scheduling have resource collisions / overlaps.

[0254] Table 1-4: Priority of receiving the DL signal with dynamic scheduling compared to transmitting the UL signal with dynamic scheduling

[0255]

[0256]

[0257] Whether Mode 1-4-1 receives the first DL signal with dynamic scheduling or transmits the UL signal with dynamic scheduling depends on the UE implementation; the priority of receiving other DL signals with dynamic scheduling is higher than the priority of transmitting the UL signal with dynamic scheduling.

[0258] Mode 1-4-1 is composed of Mode 1-1-1 and Mode 1-2-5 in Tables 1-1 / 2.

[0259] The fact that the priority of receiving other DL signals with dynamic scheduling is higher than the priority of transmitting the UL signal with dynamic scheduling is reflected in: If the UE receives the first DCI sent by the network, and this DCI is used to instruct the UE to transmit a UL signal on the first resource (for example, some symbols) (corresponding to the low-priority signal B above), and if the UE does not receive the second DCI sent by the network, and this DCI is used to instruct the UE to receive other DL signals on the first resource or at least / any part of the first resource (for example, one symbol) (corresponding to the high-priority signal A above), then the UE transmits the UL signal. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not transmit the UL signal.

[0260] Whether Mode 1-4-2 receives the first DL signal based on dynamic scheduling or transmits the UL signal based on dynamic scheduling depends on the UE implementation; the priority of receiving other DL signals based on dynamic scheduling is lower than the priority of transmitting the UL signal based on dynamic scheduling.

[0261] Mode 1-4-2 is composed of Mode 1-1-1 and Mode 1-2-9 in Table 1-1 / 2.

[0262] The fact that the priority of receiving other DL signals based on dynamic scheduling is lower than the priority of transmitting the UL signal based on dynamic scheduling is reflected in: If the UE receives the first DCI sent by the network, this DCI is used to instruct the UE to receive other DL signals (corresponding to the above-mentioned low-priority signal B) on the first resource (for example, some symbols), and if the UE does not receive the second DCI sent by the network, this DCI is used to instruct the UE to transmit the UL signal (corresponding to the above-mentioned high-priority signal A) on the first resource or at least / any part of the first resource (for example, one symbol), then the UE receives the said other DL signals. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not receive the said other DL signals.

[0263] In Mode 1-4-3, the priority of receiving the first DL signal based on dynamic scheduling is higher than the priority of transmitting the UL signal based on dynamic scheduling; the priority of receiving other DL signals based on dynamic scheduling is lower than the priority of transmitting the UL signal based on dynamic scheduling, or whether to receive other DL signals based on dynamic scheduling or transmit the UL signal based on dynamic scheduling depends on the UE implementation.

[0264] Mode 1-4-3 is composed of Mode 1-1-5 and Mode 1-2-9 / 1 in Table 1-1 / 2.

[0265] The fact that the priority of receiving the first DL signal based on dynamic scheduling is higher than the priority of transmitting the UL signal based on dynamic scheduling is reflected in: If the UE receives the first DCI sent by the network, this DCI is used to instruct the UE to transmit the UL signal (corresponding to the above-mentioned low-priority signal B) on the first resource (for example, some symbols), and if the UE does not receive the second DCI sent by the network, this DCI is used to instruct the UE to receive the first DL signal (corresponding to the above-mentioned high-priority signal A) on the first resource or at least / any part of the first resource (for example, one symbol), then the UE transmits the said UL signal. Conversely, that is, if the UE receives the second DCI sent by the network, then the UE does not transmit the said UL signal.

[0266] The fact that the priority of receiving other DL signals based on dynamic scheduling is lower than the priority of transmitting the UL signal based on dynamic scheduling is reflected in: the same as in Mode 1-4-2.

[0267] For Mode 1-4-4, the priority of receiving the first DL signal based on dynamic scheduling is lower than that of transmitting the UL signal based on dynamic scheduling; the priority of receiving other DL signals based on dynamic scheduling is higher than that of transmitting the UL signal based on dynamic scheduling, or whether to receive other DL signals based on dynamic scheduling or transmit the UL signal based on dynamic scheduling depends on the UE implementation.

[0268] Mode 1-4-4 is composed of Mode 1-1-9 and Mode 1-2-5 / 1 in Table 1-1 / 2.

[0269] The first DL signal in Mode 1-4-4 is equivalent to the other DL signals in Mode 1-4-3 above, and the other DL signals are equivalent to the first DL signal in Mode 1-4-3 above.

[0270] Example 3: The first DL signal vs. the first UL signal; the first DL signal vs. other UL signals; the first UL signal vs. other DL signals; other DL signals vs. other UL signals.

[0271] When there is a collision with the DL signal based on dynamic scheduling, different priority rules are adopted for the first UL signal based on dynamic scheduling and other UL signals. Also, when there is a collision with the UL signal based on dynamic scheduling, different priority rules are adopted for the first DL signal based on dynamic scheduling and other DL signals. Therefore, different from Example 1 and Example 2, neither the UL signals nor the DL signals in Example 3 can be considered as a whole to consider the priority.

[0272] According to the combinations of various modes in Table 1-1 and Table 1-2, Table 1-5 lists some typical priority schemes.

[0273] Table 1-5: Priority of Transmitting the UL Signal Based on Dynamic Scheduling Compared with Receiving the DL Signal Based on Dynamic Scheduling

[0274]

[0275] Mode 1-5-1:

[0276] Whether to receive the first DL signal based on dynamic scheduling or transmit the UL signal based on dynamic scheduling (including the first UL signal and other UL signals) depends on the UE implementation;

[0277] The priority of transmitting the first UL signal based on dynamic scheduling is higher than that of receiving other DL signals based on dynamic scheduling;

[0278] The priority of receiving other DL signals based on dynamic scheduling is higher than that of transmitting other UL signals based on dynamic scheduling.

[0279] Mode 1-5-2:

[0280] Whether to receive the first DL signal with dynamic scheduling or to send the first UL signal with dynamic scheduling depends on the UE implementation;

[0281] The priority of sending the first UL signal with dynamic scheduling is higher than the priority of receiving other DL signals with dynamic scheduling;

[0282] The priority of receiving DL signals with dynamic scheduling (including the first DL signal and other DL signals) is higher than the priority of sending other UL signals with dynamic scheduling.

[0283] Method 1-5-3:

[0284] Whether to receive the first DL signal with dynamic scheduling or to send the first UL signal with dynamic scheduling depends on the UE implementation;

[0285] The priority of receiving the first DL signal with dynamic scheduling is higher than the priority of sending other UL signals with dynamic scheduling;

[0286] The priority of sending UL signals with dynamic scheduling (including the first UL signal and other UL signals) is higher than the priority of receiving other DL signals with dynamic scheduling;

[0287] Method 1-5-4:

[0288] The priority of sending the first UL signal with dynamic scheduling is higher than the priority of receiving DL signals with dynamic scheduling (including the first DL signal and other DL signals);

[0289] Whether to receive the first DL signal with dynamic scheduling or to send other UL signals with dynamic scheduling depends on the UE implementation;

[0290] The priority of receiving other DL signals with dynamic scheduling is higher than the priority of sending other UL signals with dynamic scheduling.

[0291] Method 1-5-5:

[0292] The priority of sending the first UL signal with dynamic scheduling is higher than the priority of receiving DL signals with dynamic scheduling (including the first DL signal and other DL signals);

[0293] Whether to receive the first DL signal with dynamic scheduling or to send other UL signals with dynamic scheduling depends on the UE implementation;

[0294] The priority of sending other UL signals with dynamic scheduling is higher than the priority of receiving other DL signals with dynamic scheduling;

[0295] Method 1-5-6:

[0296] The priority of receiving the first DL signal with dynamic scheduling is higher than the priority of sending UL signals with dynamic scheduling (including the first UL signal and other UL signals);

[0297] The priority of the first UL signal sent with dynamic scheduling is higher than the priority of other DL signals received with dynamic scheduling;

[0298] The priority of other DL signals received with dynamic scheduling is higher than the priority of other UL signals sent with dynamic scheduling.

[0299] Method 1-5-7:

[0300] Whether it is the first DL signal received with dynamic scheduling or the UL signal (including the first UL signal and other UL signals) sent with dynamic scheduling depends on the UE implementation;

[0301] The priority of the UL signals (including the first UL signal and other UL signals) sent with dynamic scheduling is higher than the priority of other DL signals received with dynamic scheduling.

[0302] Example 4:

[0303] As described above, any combination of any method in Table 1-1 and any method in Table 1-2 is a solution to the overlap / collision between the UL signal and the DL signal with dynamic scheduling. Some solutions formed by combining some methods in Table 1-1 and some methods in Table 1-2 are shown in Example 1, Example 2 and Example 3.

[0304] When the DL signal received with dynamic scheduling overlaps / collides with the UL signal sent with dynamic scheduling, the default priority is the solution formed by any combination of any method in Table 1-1 and any method in Table 1-2.

[0305] In Example 4, the network is further allowed to rewrite the above default priority through signaling. For example, the network configures or indicates the priority between the DL signal received with dynamic scheduling and the UL signal sent with dynamic scheduling through system information (such as SIB1 / SIB19), RRC signaling, MAC CE or DCI signaling. When the network does not configure / indicate the above signaling or the UE does not detect the above signaling, the UE processes according to the default priority. When the network configures / indicates the above signaling or the UE detects the above signaling, the UE processes as follows.

[0306] Method 1: The transmission priority configured / indicated by the priority signaling sent by the network applies to all DL signals and all UL signals with dynamic scheduling.

[0307] For example, if the network configuration sets the priority of receiving DL signals higher than that of sending UL signals, then the priority of receiving all dynamically scheduled DL signals is higher than that of sending all dynamically scheduled UL signals. All DL signals here include the first DL signal and other DL signals, and all UL signals include the first UL signal and other UL signals. Vice versa.

[0308] Method 2: The transmission priority configured / indicated by the network priority signaling only applies to the collision / overlap between other DL signals except the first DL signal and all UL signals.

[0309] For example, in Method 1-4-1: "Whether to receive the first DL signal based on dynamic scheduling or send the UL signal based on dynamic scheduling depends on the UE implementation; the priority of receiving other dynamically scheduled DL signals is higher than the priority of sending dynamically scheduled UL signals." The above is the default transmission priority. If the network configures / indicates that the priority of receiving DL signals is higher than that of sending UL signals, then both priorities in Method 1-4-1 remain unchanged. If the network configures / indicates that the priority of receiving DL signals is lower than that of sending UL signals, then the first priority in Method 1-4-1 remains unchanged, while the second priority is rewritten.

[0310] Method 3: The transmission priority configured / indicated by the network priority signaling only applies to the collision / overlap between other UL signals except the first UL signal and all DL signals.

[0311] For example, in Method 1-3-1: "Whether to send the first UL signal based on dynamic scheduling or receive the DL signal based on dynamic scheduling depends on the UE implementation; the priority of sending other dynamically scheduled UL signals is higher than the priority of receiving dynamically scheduled DL signals." The above is the default transmission priority. If the network configures / indicates that the priority of sending UL signals is higher than that of receiving DL signals, then both priorities in Method 1-3-1 remain unchanged. If the network configures / indicates that the priority of sending UL signals is lower than that of receiving DL signals, then the first priority in Method 1-3-1 remains unchanged, while the second priority is rewritten.

[0312] Method 4: The transmission priority configured / indicated by the network priority signaling only applies to the collision / overlap between other DL signals except the first DL signal and other UL signals except the first UL signal.

[0313] For example, in Mode 1-5-1: "Whether to receive the first dynamically scheduled DL signal or transmit the dynamically scheduled UL signal (including the first UL signal and other UL signals) depends on the UE implementation; the priority of transmitting the first dynamically scheduled UL signal is higher than the priority of receiving other dynamically scheduled DL signals; the priority of receiving other dynamically scheduled DL signals is higher than the priority of transmitting other dynamically scheduled UL signals." The above are the default transmission priorities. If the network configures / indicates that the priority of receiving DL signals is higher than the priority of transmitting UL signals, then the three priorities in Mode 1-5-1 remain unchanged. If the network configures / indicates that the priority of receiving DL signals is lower than the priority of transmitting UL signals, then the first / second priorities in Mode 1-5-1 remain unchanged, while the third priority is rewritten.

[0314] For another example, in Mode 1-5-4: "The priority of transmitting the first dynamically scheduled UL signal is higher than the priority of receiving the dynamically scheduled DL signal (including the first DL signal and other DL signals); whether to receive the first dynamically scheduled DL signal or transmit other dynamically scheduled UL signals depends on the UE implementation; the priority of receiving other dynamically scheduled DL signals is higher than the priority of transmitting other dynamically scheduled UL signals." The above are the default transmission priorities. If the network configures / indicates the priority signaling that the priority of receiving DL signals is higher than the priority of transmitting UL signals, then the three priorities in Mode 1-5-4 remain unchanged. If the network configures / indicates the priority signaling that the priority of receiving DL signals is lower than the priority of transmitting UL signals, then the first / second priorities in Mode 1-5-4 remain unchanged, while the third priority is rewritten.

[0315] For another example, in Mode 1-4-2 / Mode 1-5-7: Whether to receive the first dynamically scheduled DL signal or transmit the dynamically scheduled UL signal depends on the UE implementation; the priority of receiving other dynamically scheduled DL signals is lower than the priority of transmitting the dynamically scheduled UL signal (including the first UL signal and other UL signals). The above are the default transmission priorities. If the network configures / indicates the priority signaling that the priority of receiving DL signals is lower than the priority of transmitting UL signals, then the two priorities in Mode 1-4-2 / Mode 1-5-7 remain unchanged. If the network configures / indicates the priority signaling that the priority of receiving DL signals is higher than the priority of transmitting UL signals, then the first priority in Mode 1-4-2 / Mode 1-5-7 remains unchanged, while in the second one, "the priority of receiving other dynamically scheduled DL signals is lower than the priority of transmitting other dynamically scheduled UL signals" is rewritten.

[0316] Method 5: The priority signaling configured / indicated by the network is the inverted priority. After the network configures / indicates the above-mentioned priority signaling or the UE detects the above-mentioned priority signaling, one or more combinations among Methods 5-1 to 5-5 are executed (for example, Method 5-1 is combined with other methods). If the network does not configure / indicate the above-mentioned priority signaling or the UE does not detect the above-mentioned priority signaling, the default transmission priority remains unchanged:

[0317] Method 5-1: Invert / rewrite the "high" priority in the default transmission priority to "low" priority (that is, invert the priority of the high-priority uplink signal or downlink signal to low priority), and / or, invert / rewrite the "low" priority to "high" priority (that is, invert the priority of the low-priority uplink signal or downlink signal to high priority), and / or, if the priority depends on "UE implementation", no inversion / rewriting is performed (that is, when the priorities of the uplink signal and the downlink signal depend on the UE implementation, the priority is not inverted).

[0318] Method 5-2: Invert the priority for the default transmission priority in case of collision / overlap between all DL signals and all UL signals.

[0319] Method 5-3: Invert the priority only for the default transmission priority in case of collision / overlap between other DL signals except the first DL signal and all UL signals.

[0320] Method 5-4: Invert the priority only for the default transmission priority in case of collision / overlap between other UL signals except the first UL signal and all DL signals.

[0321] Method 5-5: Invert the priority only for the default transmission priority in case of collision / overlap between other DL signals except the first DL signal and other UL signals except the first UL signal.

[0322] Embodiment 2

[0323] For the case where resource collision / overlap occurs between the reception of semi-statically configured DL signals and the transmission of semi-static UL signals:

[0324] For UEs of types such as HD-FDD or TDD, when resource collision / overlap occurs between the reception of semi-statically configured DL signals and the transmission of semi-static UL signals, the solution in Embodiment 1 can also be adopted. The solution in Embodiment 1 only needs to be modified as follows to be adopted.

[0325] 1. Replace "dynamic scheduling" in Embodiment 1 with "semi-static configuration";

[0326] 2. Modify the DL signal / first DL signal / other DL signals, UL signal / first UL signal / other UL signals in Embodiment 1 to;

[0327] The DL signal includes at least one of the following: PDCCH CSS sets of different types such as Type-0 / 0A / 0B / 1 / 1A / 2 / 2A / 3, PDCCH with USS set, PDSCH, (SP / P-)CSI-RS, PRS, PSS / SSS / PBCH / SSB;

[0328] The first DL signal includes one or more of the DL signals (for example, PDCCH CSS sets of different types such as Type-0 / 0A / 1 / 2). The other DL signals include one or more signals in the DL signal except the first DL signal.

[0329] The UL signal includes at least one of the following: (configured grant) PUSCH, (SP / P-)SRS, PUCCH, PRACH.

[0330] The first UL signal includes one or more of the UL signals (for example, PUCCH carrying HARQ-ACK / SR / CSI). The other UL signals include one or more signals in the UL signal except the first UL signal.

[0331] Similarly, any one way in Table 1-1 combined with any one way in Table 1-2 is a complete solution to the overlap / collision of semi-statically configured DL signals and semi-statically configured UL signals.

[0332] For the resource collision / overlap between the reception of semi-statically configured DL signals and the transmission of semi-static UL signals, different solutions can also be adopted for UEs in different states.

[0333] For example, if the UE is in the RRC connected state (RRC_CONNECTED), the solution in Method 1-4-1 can be adopted. That is, whether to receive the first DL signal configured semi-statically (such as the PDCCH configured by the Type-0 / 0A / 1 / 2-PDCCH common search space set) or to transmit the UL signal configured semi-statically depends on the UE implementation; the priority of receiving other DL signals configured semi-statically is by default higher than that of transmitting the UL signal configured semi-statically. If the UE is in the RRC inactive state (RRC_INACTIVE), a combined solution of Method 1-1-1 and Method 1-2-1 can be adopted. That is, whether to receive the DL signal configured semi-statically (such as the PDCCH configured by the Type-0 / 0A / 0B / 1 / 2-PDCCH common search space set) or to transmit the UL signal configured semi-statically depends on the UE implementation, or by default receive the DL signal configured semi-statically (without transmitting the UL signal), or by default transmit the semi-static UL signal (without receiving the DL signal).

[0334] Embodiment 3

[0335] For the case where resources collide / overlap between one / multiple DL transmissions and one / multiple UL transmissions:

[0336] This embodiment addresses the problem of resource collision / overlap between one / multiple DL transmissions and one / multiple UL transmissions. One DL transmission or one UL transmission may include the reception of one DL signal or the transmission of one UL signal. "Time" can also be equivalent to "one".

[0337] The above-mentioned resource collision / overlap between one / multiple DL transmissions and one / multiple UL transmissions may include the following three cases: resource collision / overlap between one DL transmission and multiple UL transmissions, resource collision / overlap between one UL transmission and multiple DL transmissions, and resource collision / overlap between multiple DL transmissions and multiple UL transmissions. The above three problems of resource collision / overlap can be solved by at least one or a combination of the following methods.

[0338] Method 1: When resources collide / overlap between one / multiple DL transmissions and one / multiple UL transmissions, if one / multiple DL transmissions include the first DL signal, it is uniformly processed according to the priority processing method for the resource collision / overlap between the first DL signal and the UL signal.

[0339] Taking the collision / overlap between the semi-statically configured DL signal and the semi-statically configured UL signal in Embodiment 2 as an example, assume that the first DL signal is PDCCH with Type0 / 0A / 1 / 2-PDCCH CSS set. When the first DL signal / other DL signals collide / overlap with the UL signal, the priority rule adopted is: whether to receive the first DL signal or transmit the UL signal depends on the UE implementation; the priority of receiving other DL signals is by default higher than the priority of transmitting the UL signal, but the priority of other DL signals and the UL signal can be rewritten through network configuration. Figure 4 It is a schematic diagram of the collision or overlap between a semi-statically configured DL signal and a semi-statically configured UL signal provided by an embodiment of the present application. Based on this example, as Figure 4 shown, when two DL signals collide / overlap with one UL signal in terms of resources, regardless of whether the first DL signal is in the front or the back, it is uniformly processed in the manner of the collision / overlap between the first DL signal and the UL signal resources. That is to say, in this example, whether to receive the first DL signal / other DL signals or transmit the UL signal is determined by the UE implementation.

[0340] Method 2: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions in terms of resources, if one / multiple UL transmissions include the first UL signal, it is uniformly processed in the priority processing manner of the collision / overlap between the first UL signal and the DL signal resources.

[0341] Taking the example of Method 1-3-3 in Example 1 of Embodiment 1 as an example, when the first UL signal / other UL signals collide / overlap with the DL signal, the priority rule adopted is: the priority of transmitting the first UL signal is higher than the priority of receiving the DL signal; the priority of transmitting other UL signals is lower than the priority of receiving the DL signal, or whether to transmit other UL signals or receive the DL signal depends on the UE implementation. Figure 5 It is a schematic diagram of the collision or overlap between a dynamically scheduled DL signal and a dynamically scheduled UL signal provided by an embodiment of the present application. Based on this example, as Figure 5 shown, when two UL signals collide / overlap with one DL signal in terms of resources, regardless of whether the first UL signal is in the front or the back, it is uniformly processed in the manner of the collision / overlap between the first UL signal and the DL signal resources. That is to say, in this example, the priority of transmitting the first UL signal and other UL signals is higher than the priority of receiving the DL signal.

[0342] Method 3: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions in terms of resources, if one / multiple DL transmissions include the first DL signal and if one / multiple UL transmissions include the first UL signal, it is uniformly processed in the priority processing manner of the collision / overlap between the first DL signal and the first UL signal resources.

[0343] Taking Example 1 of Example 3, Mode 1-5-1 as an example, when the first DL signal / other DL signals collide / overlap with the first UL signal / other UL signals, the adopted priority rules are as follows: Whether to receive the dynamically scheduled first DL signal or transmit the dynamically scheduled UL signals (including the first UL signal and other UL signals) depends on the UE implementation; The priority of transmitting the dynamically scheduled first UL signal is higher than the priority of receiving the dynamically scheduled other DL signals; The priority of receiving the dynamically scheduled other DL signals is higher than the priority of transmitting the dynamically scheduled other UL signals.

[0344] Figure 6 It is a schematic diagram of the collision or overlap between another dynamically scheduled DL signal and a dynamically scheduled UL signal provided by an embodiment of the present application. Based on this example, as Figure 6 shown, when there is a resource collision / overlap between two UL signals and two DL signals, regardless of whether the time domain positions of the first DL signal and the first UL signal are in the front or in the back, it is uniformly processed in the same way as the resource collision / overlap between the first DL signal and the first UL signal. That is to say, in this example, whether to receive the DL signal or transmit the UL signal is determined by the UE implementation.

[0345] If taking Example 1 of Example 3, Mode 1-5-4 as an example, then when there is a resource collision / overlap between two UL signals and two DL signals, the priority of transmitting the UL signal is higher than the priority of receiving the DL signal.

[0346] Mode 4: When there is a resource collision / overlap between one / multiple DL transmissions and one / multiple UL transmissions, it is uniformly processed in the same way as the resource collision / overlap between the 1st DL transmission and the 1st UL transmission.

[0347] For example, in the example of (a) in Figure 4 , all signals are uniformly processed in the same way as the resource collision / overlap between the first DL signal configured semi-statically and the UL signal configured semi-statically, that is, it is all determined by the UE implementation; In the example of (b) in Figure 4 , all signals are uniformly processed in the same way as the resource collision / overlap between the other DL signals configured semi-statically and the UL signal configured semi-statically, that is, the priority of receiving the DL signal is higher than the priority of the UL signal, or it is determined by the network configuration.

[0348] Another example, in the example of (a) in Figure 5 , all signals are uniformly processed in the same way as the resource collision / overlap between the first UL signal scheduled dynamically and the DL signal scheduled dynamically, that is, the priority of transmitting the UL signal is higher than the priority of receiving the DL signal; In Figure 5In the example of (b), all signals are uniformly processed in the same way as the resource collision / overlap between other UL signals with dynamic scheduling and DL signals with dynamic scheduling, that is, the priority of transmitting UL signals is lower than that of receiving DL signals, or it depends on the UE implementation.

[0349] For another example, in Figure 6 In the example of (a), all signals are uniformly processed in the same way as the resource collision / overlap between the first DL signal with dynamic scheduling and the first UL signal with dynamic scheduling, that is, it depends on the UE implementation; in Figure 6 In the example of (b), all signals are uniformly processed in the same way as the resource collision / overlap between other DL signals with dynamic scheduling and other UL signals with dynamic scheduling, that is, the priority of receiving DL signals is higher than that of UL signals.

[0350] Method 5: When resource collision / overlap occurs between one / multiple DL transmissions and one / multiple UL transmissions, if a certain DL transmission included in the one / multiple DL transmissions has a higher priority, then receive all DL transmissions and cancel all UL transmissions. For example, the DL transmissions include signals with dynamic scheduling, and the UL transmissions are all signals with semi-static configuration.

[0351] Method 6: When resource collision / overlap occurs between one / multiple DL transmissions and one / multiple UL transmissions, if a certain UL transmission included in the one / multiple UL transmissions has a higher priority, then receive all UL transmissions and cancel all DL transmissions. For example, the UL transmissions include signals with dynamic scheduling, and the DL transmissions are all signals with semi-static configuration.

[0352] Method 7: When resource collision / overlap occurs between one / multiple DL transmissions and one / multiple UL transmissions, solve the collision of each DL transmission and UL transmission in sequence according to the time sequence.

[0353] Method 8: When resource collision / overlap occurs between one / multiple DL transmissions and one / multiple UL transmissions, it depends on the UE implementation; or when the multiple transmissions with resource overlap include the first DL signal and / or the first UL signal, whether to receive the DL signal or transmit the UL signal depends on the UE implementation.

[0354] Embodiment 4

[0355] For the case of in-device coexistence (IDC) between NTN and another functional device:

[0356] To allow users to access various networks and services ubiquitously, more and more UEs are equipped with multiple radio transceivers. For example, the same UE can be equipped with NR / LTE, WiFi, and Bluetooth transceivers, as well as a Global Navigation Satellite System (GNSS) receiver (such as GPS, Galileo, GLONASS, Beidou Satellite Navigation System, etc.). Due to the extreme proximity of multiple radio transceivers within the same UE operating at adjacent frequencies or sub-harmonic frequencies, the interference power from co-located radio transmitters may be much higher than the actual received power level of the signal required by the receiver. This situation can lead to IDC interference, which is called the IDC problem.

[0357] Figure 7 FIG. Figure 7 is a schematic diagram of a scenario of IDC interference provided by the prior art. As follows Figure 7 As shown, there is also an IDC interference problem between the radio transceiver of the NTN function and other function receivers inside the same UE. For example, when the adjacent frequency band is transmitting NTN uplink (UL) signals, it will cause great interference to the GNSS receiver, and at this time, it is impossible to ensure simultaneous NTN transmission and GNSS reception.

[0358] Therefore, it is necessary to improve the existing IDC functions and solutions to solve the IDC interference problem between NTN transmission and the other party's transmission (including GNSS, Bluetooth (BT), Wireless Fidelity (WiFi), New Radio (NR) (such as NR-U) / LTE (such as LAA) / others, etc., taking GNSS as an example in the following solution).

[0359] If an IDC interference problem occurs during the simultaneous transmission of NTN (for example, the UE sends an NTN UL signal) and the other party (for example, the UE receives a GNSS signal), it can be solved by any one of the following solutions or a combination of multiple solutions.

[0360] Solution 1: Introduce a new UE capability for the NTN UE. This capability is used to indicate whether the UE supports IDC assistance information, which at least includes the assistance information of the IDC between NTN and the other party (such as GNSS). One or more of the information in the IDC assistance information can be reported by the UE to the network or configured by the network to the UE to assist in solving the IDC interference problem.

[0361] Optionally, the NTN UE reports / indicates the above UE capability to the network.

[0362] Optionally, the network indicates whether the UE is allowed to send the IDC indication via Radio Resource Control (RRC) signaling (such as dedicated RRC signaling), MAC CE, or DCI signaling.

[0363] Solution 2: The UE reports the IDC information (or the aforementioned IDC auxiliary information) to the network.

[0364] Optionally, the UE is a UE with the new UE capabilities in Solution 1, that is, the UE supports the auxiliary information of the IDC between the NTN and the other party.

[0365] Optionally, after the network indicates that the UE is allowed to send the IDC indication, the UE can report the NTN-related IDC information to the network. Or, after the network indicates that the UE is allowed to send the IDC indication, if the UE has not reported the IDC information or the IDC information has changed based on the detected IDC problem, the UE reports the IDC information to the network.

[0366] The reported IDC information includes at least one of the following:

[0387] The UE can send IDC information to the network in the UE assistance message reported by the UE to the network.

[0388] Solution 3: The network configures an IDC solution for the UE. It can include at least one of the following solutions:

[0389] · Time-domain solution. For example, NTN and the other party adopt a TDM / DRX solution, and the configuration information of this solution includes:

[0391] · Frequency-domain solution. For example, NTN and the other party adopt an FDM solution.

The configuration information of this solution includes the frequency-domain information for configuring the target frequency-domain resource. The frequency-domain information includes at least one of the following: frequency range (such as start and end frequencies, start frequency and bandwidth, or center frequency and bandwidth), carrier / band, frequency of the carrier / band, frequency range of the carrier / band, carrier / band group, carrier / band combination, carrier / band frequency range combination, sub-band, resource element / resource block, partial bandwidth (BWP), passband, cell, etc.

[0392] · Other solutions. For example, the network configures the maximum transmit power, power leakage threshold, or interference threshold of NTN or the other party for the UE. When the UE transmit power exceeds the above maximum transmit power or threshold, an IDC interference solution needs to be executed. Another example is a solution implemented through network scheduling to solve the IDC problem.

[0393] The network can configure / indicate the IDC solution for the UE through RRC signaling (e.g., dedicated RRC signaling), MAC CE, or DCI signaling.

[0394] Solution 4: The UE cancels the transmission of one party on its own.

[0395] Solution 4-1: Based on network configuration, the UE can cancel the NTN transmission (e.g., sending NTN uplink signals) on its own to protect the transmission of the other party (e.g., receiving GNSS signals).

[0396] The network configures the probability of canceling the NTN transmission within a certain duration / long term through signaling (e.g., dedicated RRC signaling) to limit the number of NTN transmissions canceled autonomously. Once the network configuration is obtained, the UE can cancel the NTN transmission on its own. Otherwise, the UE shall not cancel any NTN transmission on its own.

[0397] In this solution, as long as the specific restrictions / requirements of the network configuration are met, the UE can decide on its own which NTN transmission to cancel.

[0398] Solution 4-2: Based on the UE's autonomous decision-making, the UE can cancel the NTN transmission on its own to protect the transmission of the other party. This solution is not subject to network configuration constraints.

[0399] In this solution, without any restrictions from the network side, the UE can decide on its own which NTN transmission to cancel.

[0400] Solution 4-3: Based on network configuration, the UE can cancel the transmission of the other party (e.g., receiving GNSS signals) on its own to ensure connection to the NTN network, thereby performing necessary access procedures, such as RRC connection reconfiguration, receiving paging, receiving synchronization signals / broadcast channels, receiving PDCCH configured by the common search space and / or system information scheduled by it, or sending PRACH, etc.

[0401] The network configures the probability of canceling the GNSS transmission within a certain duration / long term through signaling (e.g., dedicated RRC signaling) to limit the number of GNSS transmissions canceled autonomously. Once the network configuration is obtained, the UE can cancel the GNSS transmission on its own. Otherwise, the UE shall not cancel any GNSS transmission on its own.

[0402] In this solution, as long as the specific restrictions / requirements of the network configuration are met, the UE can decide on its own which GNSS reception to cancel.

[0403] Solution 4-4: Based on the UE's autonomous decision-making, the UE can cancel the transmission of the other party (e.g., receiving GNSS signals) on its own to ensure connection to the NTN network, thereby performing necessary access procedures, such as RRC connection reconfiguration, receiving paging, receiving synchronization signals / broadcast channels, receiving PDCCH configured by the common search space and / or system information scheduled by it, or sending PRACH, etc. This solution is not subject to network configuration constraints.

[0404] In this solution, without any restrictions from the network side, the UE can independently decide which GNSS reception to cancel.

[0405] For Solutions 4-1 to 4-4, the cancelled NTN transmissions can be one or more of the following types: transmissions overlapping with GNSS time-domain resources, overlapping parts of transmissions overlapping with GNSS time-domain resources, single transmissions overlapping with GNSS time-domain resources, overlapping parts of single transmissions overlapping with GNSS time-domain resources, all transmissions overlapping with GNSS time-domain resources, and all repeated transmissions related to transmissions overlapping with GNSS time-domain resources. The cancelled GNSS transmissions can adopt similar methods as above. For example, transmissions overlapping with the time-domain resources of NTN transmissions, overlapping parts of transmissions overlapping with the time-domain resources of NTN transmissions, etc. The above-mentioned types of cancelled NTN / GNSS transmissions can also be determined according to the network configuration, that is, the network configures which type of the above-mentioned cancelled NTN transmissions it is.

[0406] In this application, the timing for the UE to execute the IDC solution can be at least one of the following:

[0407] Solution 5-1: The UE executes the IDC solution according to the latest timing on the UE side, that is, according to the latest TA obtained on the UE side, to execute the above IDC solution.

[0408] Solution 5-2: The UE executes the IDC solution according to the TA reported to the network last / most recently, that is, according to the timing of the UE side recognized by the base station side, to execute the above solution.

[0409] Solution 5-3: The UE combines the timing of the latest TA on the UE side and the timing of the TA reported to the network last / most recently, and executes the above solution on the time-domain resources where the NTN transmission (for example, NTN UL) overlaps with the transmission of the other party.

[0410] For example, if based on the timing of the latest TA on the UE side, the NTN UL transmission overlaps with the GNSS reception in time period T1. If based on the timing of the TA reported by the UE to the network last / most recently, the NTN UL transmission overlaps with the GNSS reception in time period T2. For Solution 5-1, the UE only executes Solution 4 or other solutions in time period T1. For Solution 5-2, the UE only executes Solution 4 or other solutions in time period T2. For Solution 5-3, then in time period T1 and time period T2, the UE executes Solution 4 or other solutions.
