Description

Signal transmission methods, equipment and storage media Technical Field

[0001] This application relates to the field of communication technology, specifically to a signal transmission method, device, and storage medium. Background Technology

[0002] In 5G and even 6G wireless communication systems, scenarios with high transmission latency or high mobility, such as non-terrestrial networks (NTN), are supported. Due to the existence of high transmission latency and the rapid movement of satellites and user equipment (UE), there is a significant error between the timing advance (TA) recognized by the network side (based on the UE's previous TA report) and the actual TA being used by the UE. This leads to conflicts between uplink and downlink resources on the equipment side in types such as half-duplex-frequency division duplex (HD-FDD) or time division duplex (TDD).

[0028] The embodiments of this application will be described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this application.

[0029] Figure 1 is a schematic diagram of an NTN architecture provided by related technologies. As shown in Figure 1, in the NTN communication system, the link between the user equipment (UE) and the satellite is a service link, and the link between the access network equipment (such as base station and gateway station) and the satellite is a feeder link. Furthermore, the link is common to all UEs in the same cell (UE1 and UEx shown in Figure 1).

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

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

[0032] Case 1: Collision / overlap between dynamically scheduled downlink (DL) signal reception and semi-statically configured uplink (UL) signal transmission;

[0033] Case 2: Collision / overlap between semi-static DL signal reception and dynamically scheduled UL signal transmission;

[0034] Case 3: Collision / overlap between semi-static DL signal reception and semi-static UL signal transmission;

[0035] Case 4: Collision / overlap between dynamically scheduled DL signal reception and dynamically scheduled UL signal transmission;

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

[0037] Case 6: Collision / overlap of dynamic or semi-static downlink signals with valid random access opportunities (ROs).

[0038] Dynamic scheduling in the above cases refers to the network (e.g., base stations, satellites, relay nodes, etc.) sending downlink control information (DCI) to schedule or instruct the UE to receive DL signals or send UL signals (e.g., the DL signal can be the Physical Downlink Shared Channel (PDSCH) (such as System Information Block 19 (SIB19)) or Channel State Information Reference Signal (CSI-RS), and the UL signal can be the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH) / First Random Access Message (MsgA), or Sounding Reference Signal (SRS)). Semi-static configuration refers to the network configuring the UE to receive DL signals or send UL signals through higher-layer parameters (for example, DL signals can be Physical Downlink Control Channel (PDCCH), PDSCH, Synchronization Signal / PBCH Block (SSB), CSI-RS, or Downlink Positioning Reference Signal (DL-PRS), and UL signals can be PUCCH, PUSCH, or SRS).

[0039] The collisions / overlaps in the above cases include: collisions between two types of signals (e.g., DL signal reception and UL signal transmission) due to overlapping time-frequency resources, and / or collisions between two types of signals even if their time-frequency resources do not overlap, due to insufficient uplink / downlink handover time. For example, at least N seconds must be allowed between DL reception and UL transmission. Rx-Tx ·T c An interval is necessary to avoid collisions; at least N intervals must be maintained between UL transmission and DL reception. Tx-Rx ·T c Spacing out will prevent collisions. c N is the basic time unit for access technology. Rx-Tx N Tx-RxThese represent the number of basic time units required to switch from receiving to transmitting and from transmitting to receiving, respectively.

[0040] For Case 1, Case 2, Case 5 and Case 6, the solution to the resource collision / overlap problem caused by TA mismatch can reuse the RedCap UE and its corresponding network to handle the same Case.

[0041] For Cases 3 and 4, existing rules classify these two cases as erroneous use cases. That is, the UE does not expect simultaneous semi-static DL reception and semi-static UL transmission, or simultaneously dynamically scheduled DL reception and dynamically scheduled UL transmission. Accordingly, the network will not perform such configuration or scheduling. However, in NTN communication, due to the existence of large transmission delays, there is a significant error between the timing perceived by the network and the actual timing on the UE side. Even if the network configures and instructs according to the above behavior, collisions / overlaps between semi-static DL reception and semi-static UL transmission, or between dynamically scheduled DL reception and dynamically scheduled UL transmission, may still occur on the UE side.

[0042] In one embodiment, FIG2 is a flowchart of a signal transmission method provided by an embodiment of this application. This embodiment is applied to situations where uplink and downlink signal transmission resources overlap or collide in an NTN scenario. This embodiment can be executed by a first communication node. Exemplarily, the first communication node can be a terminal side, for example, the terminal side can include, but is not limited to, one of the following: User Equipment (UE). As shown in FIG2, this embodiment includes: S210-S220.

[0043] S210. Determine transmission priority information.

[0044] In one example, transmission priority information can be indicated by a second communication node or pre-configured directly. In another example, when transmission priority information is indicated by a second communication node, the first communication node can receive the transmission priority information configured or indicated by the second communication node. In yet another example, when transmission priority information is pre-configured directly, the first communication node can directly obtain the transmission priority information, meaning it can directly configure the priority of one signal to be higher than that of another signal. For example, the priority of a first uplink signal (also called a first uplink signal, or a first UL signal) can be directly configured to be higher than that of a first downlink signal (also called a first downlink signal, or a first DL signal); or, the priority of other uplink signals (also called other uplink signals, or other UL signals) can be lower than that of the first downlink signal; or, the priority of the first uplink signal can be lower than that of the first downlink signal; the relative priorities of the first uplink signal and the first downlink signal are determined based on the UE implementation (or simply UE implementation); or, the relative priorities of other uplink signals and the first downlink signal are determined based on the UE implementation.

[0045] In one example, transmission priority information is used to characterize the relative transmission priorities of dynamically scheduled DL signals and dynamically scheduled UL signals in the event of a collision or overlap. In another example, transmission priority information is used to characterize the relative transmission priorities of semi-statically configured DL signals and semi-statically configured UL signals in the event of a collision or overlap.

[0046] S220. Transmit signals according to the determined transmission priority information.

[0047] In the event of a collision or overlap between DL and UL signals, the first communication node can transmit the DL or UL signal according to a pre-determined transmission priority information to the second communication node, thus resolving the technical problem of uplink and downlink resource conflict and effectively ensuring the transmission efficiency of uplink and downlink signals.

[0048] In one embodiment, determining transmission priority information includes: determining transmission priority information when transmission resources of uplink signals and downlink signals overlap or collide. In one example, transmission priority information can be determined when transmission resources associated with uplink signals overlap or collide with transmission resources associated with downlink signals. In one example, transmission resources may include time-domain resources.

[0049] In one embodiment, the downlink signal includes: a first downlink signal and other downlink signals; wherein, the other downlink signals include at least one signal other than the first downlink signal;

[0050] The uplink signal includes: a first uplink signal and other uplink signals; wherein, the other uplink signals include at least one signal other than the first uplink signal. In one example, the signals contained in the first downlink signal are mutually exclusive, that is, the signals contained in the two downlink signals do not overlap at all. In one example, the signals contained in the first uplink signal are mutually exclusive, that is, the signals contained in the two downlink signals do not overlap at all. In one example, both the first downlink signal and other downlink signals may contain one or more signals. In one example, both the first uplink signal and other uplink signals may contain 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: other dynamically scheduled downlink signals, or other semi-statically configured downlink signals. 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; other uplink signals may include: other dynamically scheduled uplink signals, or other semi-statically configured uplink signals.

[0051] In one embodiment, the downlink signal includes a semi-statically configured downlink signal, and the downlink signal includes at least one of the following: PDCCH; PDSCH; CSI-RS; PRS. In one example, the downlink signal including a semi-statically configured downlink signal can be understood as the downlink signal being a semi-statically configured downlink signal.

In one example, the first downlink signal of the semi-static configuration and the other downlink signals of the semi-static configuration each contain at least one signal from the downlink signals of the semi-static configuration. Furthermore, the signals contained in the first downlink signal of the semi-static configuration and the signals contained in the other downlink signals of the semi-static configuration are mutually exclusive and do not overlap. For example, assuming the first downlink signal of the semi-static configuration contains a PDCCH CSS set having at least one different type such as Type-0, Type-0A, Type-0B, Type-11A, Type-2, Type-2A, and Type-3, then the other downlink signals of the semi-static configuration contain one or more signals other than the first downlink signal.

[0055] In one example, the uplink signal of a semi-static configuration may include at least one of the following: a configuration-granted PUSCH; a PUSCH; a (Semi-Persistent / Persistent, SP / P-) SRS; or a PUCCH carrying a Hybrid Automatic Repeat Request-ACK (HARQ-ACK), a Scheduling Request (SR), or Channel State Information (CSI). In one example, the first uplink signal of the semi-static configuration and other uplink signals of the semi-static configuration each contain at least one signal from the semi-static configuration's uplink signals, and the signals contained in the first uplink signal of the semi-static configuration are mutually exclusive with the signals contained in the other uplink signals of the semi-static configuration, and the signals contained in both do not overlap. For example, assuming the first uplink signal of the semi-static configuration contains a PUCCH with HARQ-ACK, then the other uplink signals of the semi-static configuration contain one or more signals other than the first uplink signal.

[0056] In one embodiment, the downlink signal includes a dynamically scheduled downlink signal, and the dynamically scheduled downlink signal includes at least one of the following: PDSCH; CSI-RS. In one example, the downlink signal includes a dynamically scheduled downlink signal, which can be understood as the downlink signal being a dynamically scheduled downlink signal.

[0057] In one embodiment, the downlink signal includes dynamically scheduled downlink signals, and the first downlink signal includes at least one of the following: a PDSCH carrying specific information; or a CSI-RS for a specific purpose.

[0091] Receive priority signaling from the second communication node;

[0092] Priority signaling is used to indicate or update the transmission priority of uplink and downlink signals.

[0093] In one example, priority signaling is used to indicate the transmission priority of uplink and downlink signals; or, to update the transmission priority of uplink and downlink signals. For instance, assuming the priority of receiving other dynamically scheduled downlink signals is lower than the priority of transmitting dynamically scheduled uplink signals (including the first uplink signal and other uplink signals), if priority signaling carrying the message that the priority of receiving downlink signals is higher than the priority of transmitting uplink signals is received at this time, then the priority is updated according to the transmission priority indicated by the priority signaling, that is, the priority of receiving downlink signals is adjusted from lower than the priority of transmitting uplink signals to higher than the priority of transmitting uplink signals.

[0094] In one embodiment, priority signaling includes at least one of the following: system information; radio resource control signaling; media access control control element (MAC-CE) signaling; downlink control information.

[0095] In one embodiment, the scope of application of the priority signaling indicating or updating the transmission priority includes at least one of the following:

[0096] Applicable to resource collisions or overlaps between uplink and downlink signals;

[0097] It is applicable to resource collisions or overlaps between downlink signals and uplink signals other than the first downlink signal;

[0100] In one embodiment, the priority instruction is a priority inversion signaling; the priority inversion of uplink and downlink signals includes at least one of the following:

[0101] Flip the priority of a high-priority uplink or downlink signal to a low priority;

[0102] Invert the priority of a low-priority uplink or downlink signal to a high priority;

[0103] If the priorities of uplink and downlink signals depend on the UE implementation, the priorities are not flipped.

[0105] The transmission priority of downlink signals other than the first downlink signal that collide or overlap with all uplink signals is flipped.

[0106] The transmission priority is flipped for uplink signals other than the first uplink signal that have resource collisions or overlaps with all downlink signals;

[0107] The transmission priority is flipped for downlink signals other than the first downlink signal and uplink signals other than the first uplink signal where resource collisions or overlaps occur.

[0108] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, and if the at least one downlink transmission includes a first downlink signal, the transmission is processed according to the priority handling method for resource collision or overlap between the first downlink signal and the uplink signal.

[0109] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, and if the at least one uplink transmission includes a first uplink signal, the transmission is processed according to the priority handling method for resource collision or overlap between the first uplink signal and the downlink signal.

[0110] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, and if at least one downlink transmission includes a first downlink signal and at least one uplink transmission includes a first uplink signal, the processing shall be carried out in accordance with the priority processing method for resource collision or overlap between the first downlink signal and the first uplink signal.

[0111] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, the processing is carried out according to the priority processing method of the first downlink signal and the first uplink signal collide or overlap in resources.

[0112] In one embodiment, if a resource collision or overlap occurs between at least one downlink transmission and at least one uplink transmission, if one of the downlink signals included in the at least one downlink transmission has a higher priority, all downlink signals are received and all uplink signal transmissions are cancelled.

[0113] In one embodiment, if a resource collision or overlap occurs between at least one downlink transmission and at least one uplink transmission, if one of the uplink signals included in the at least one uplink transmission has a higher priority, all uplink signals are transmitted, and the transmission of all downlink signals is canceled.

[0114] In one embodiment, if at least one downlink transmission and at least one uplink transmission experience resource collisions or overlaps, the resource collisions between each downlink transmission and uplink transmission are processed sequentially according to their chronological order.

[0115] In one embodiment, in the event that at least one downlink transmission and at least one uplink transmission collide or overlap in resources, the signal transmission depends on the UE implementation.

[0116] Alternatively, in cases where multiple transmissions with overlapping resources include a first downlink signal and / or a first uplink signal, the decision to receive a downlink signal or transmit an uplink signal is determined based on the UE implementation.

[0159] In one embodiment, the signal transmission method applied to the second communication node further includes: sending a priority signaling message to the first communication node so that the first communication node indicates or updates the transmission priority of uplink and downlink signals based on the priority signaling message.

[0160] In one embodiment, the priority signaling includes at least one of the following: system information; radio resource control signaling; media access control-control unit (MAC-CE) signaling; and downlink control information.

[0161] In one embodiment, the scope of application of the priority signaling indicating or updating the transmission priority includes at least one of the following:

[0162] Applicable to resource collisions or overlaps between uplink and downlink signals;

[0163] It is applicable to resource collisions or overlaps between downlink signals and uplink signals other than the first downlink signal;

[0164] Applicable to resource collisions or overlaps between uplink and downlink signals other than the first uplink signal;

[0165] This applies to resource collisions or overlaps between downlink signals other than the first downlink signal and uplink signals other than the first uplink signal.

[0166] In one embodiment, the priority instruction is a priority inversion signaling; the priority inversion of uplink and downlink signals includes at least one of the following:

[0167] Flip the priority of a high-priority uplink or downlink signal to a low priority;

[0168] Invert the priority of a low-priority uplink or downlink signal to a high priority;

[0170] The transmission priority of all uplink and downlink signals that have resource collisions or overlaps is flipped;

[0174] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, and if the at least one downlink transmission includes a first downlink signal, the transmission is processed according to the priority handling method for resource collision or overlap between the first downlink signal and the uplink signal.

[0175] In one embodiment, if at least one downlink transmission and at least one uplink transmission collide or overlap in resources, and if the at least one uplink transmission includes a first uplink signal, the transmission is processed according to the priority handling method for resource collision or overlap between the first uplink signal and the downlink signal.

[0180] In one embodiment, if at least one downlink transmission and at least one uplink transmission experience resource collisions or overlaps, the resource collisions between each downlink transmission and uplink transmission are processed sequentially according to their chronological order.

[0181] In one embodiment, in the event that at least one downlink transmission and at least one uplink transmission collide or overlap in resources, the signal transmission depends on the UE implementation.

[0182] Alternatively, in cases where multiple transmissions with overlapping resources include a first downlink signal and / or a first uplink signal, the decision to receive a downlink signal or transmit an uplink signal is determined based on the UE implementation.

[0183] It should be noted that the explanations of parameters such as the first uplink signal, other uplink signals, first downlink signal, other downlink signals, and priority signaling involved in the signal transmission method applied to the second communication node can be found in the explanations of the corresponding parameters in the signal transmission method applied to the first communication node, and will not be repeated here.

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

[0185] Example 1

[0186] For situations where resource collisions / overlaps occur between dynamically scheduled DL signal reception and dynamically scheduled UL signal transmission:

[0187] For UEs of HD-FDD or TDD types, when dynamically scheduled DL signal reception and dynamically scheduled UL signal transmission collide / overlap, the following solution can be used:

[0188] Dynamically scheduled DL signals are divided into two categories: the first DL signal and other DL signals; 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 differs from that of other DL signals, such as the PDSCH carrying system information compared to other DL signals. Similarly, the importance of the first UL signal differs from that of other UL signals, such as PRACH or MsgA compared to other UL signals.

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

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

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

[0193] The first DL signal includes at least one of the following: a PDSCH carrying specific information, or a CSI-RS for a specific purpose. It is scheduled by a PDCCH configured from a common search space set (e.g., at least one of Type-0 / 0A-PDCCH CSS), and the system information carried may include system information such as SIB1 or SIB19. The CSI-RS for a specific purpose may be a 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 signal.

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

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

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

[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 (e.g., HARQ-ACK, scheduling request SR, or CSI feedback), the other UL signals include at least one of the following: PRACH / MsgA, PUCCH, PUSCH, and SRS carrying other information (e.g., other information in HARQ-ACK / scheduling request SR / CSI feedback besides the specific information mentioned above).

[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] In this manner, when the first UL signal is one or more of the signals {PUSCH, PUCCH, PRACH / MsgA, SRS}, the other UL signals are one or more of the signals {PUSCH, PUCCH, PRACH / MsgA, SRS} other than the first UL signal.

[0202] The priority between sending dynamically scheduled UL signals and receiving dynamically scheduled DL signals can be divided into three types: depending on the 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 higher priority of signal A (or the resource transmitted by signal A) than that of signal B (or the resource transmitted by signal B) means that: when signal A exists on a certain resource, the UE does not receive or transmit signal B; or, the UE can only receive or transmit signal B on a certain resource when signal A does not exist on that resource. Alternatively, when the resource transmitted by signal A overlaps / collides with the resource transmitted by signal B, the UE does not receive or transmit signal B; or, the UE can only receive or transmit signal B when the resource transmitted by signal B does not overlap / collide with the resource transmitted by signal A. This priority rule applies to all embodiments or examples in this application.

[0204] For example, the higher priority of transmitting the UL signal X than receiving the dynamically scheduled DL signal Y is reflected in the following: if the UE receives a first DCI transmitted by the network, which instructs the UE to receive the DL signal Y on a first resource (e.g., some symbols), and if the UE does not receive a second DCI transmitted by the network, which instructs the UE to transmit the UL signal X on the first resource or at least / any part of the first resource (e.g., one symbol), then the UE receives the DL signal Y. Conversely, if the UE receives the second DCI transmitted by the network, then the UE does not receive the DL signal Y.

[0205] For example, the lower priority of sending the UL signal X compared to receiving the dynamically scheduled DL signal Y is reflected in the following: If the UE receives a first DCI sent by the network, which instructs the UE to send the UL signal X on a first resource (e.g., some symbols), and if the UE does not receive a second DCI sent by the network, which instructs 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 sends the UL signal X. Conversely, if the UE receives the second DCI sent by the network, then the UE does not send the UL signal X.

[0206] In this application, when the received DL signal and the transmitted UL signal overlap / collide on time-frequency resources (e.g., on some symbols), not receiving the DL signal / not transmitting the UL signal includes two methods: Method 1) completely canceling the reception / transmission of the low-priority signal; Method 2) only not receiving / transmitting the corresponding part of the low-priority signal on the overlapping / colliding time-frequency resources (including necessary switching / protection resources on both sides), while on non-overlapping / non-colliding time-frequency resources, the other part of the low-priority signal can still be received / transmitted. For example, if a part of the DL signal Y (let's say Y1) overlaps / collides with the UL signal X, and the DL signal Y is a low-priority signal, in Method 1, the DL signal Y is not received at all; in Method 2, only the Y1 part of the DL signal is not received, while the other parts are still received normally.

[0207] Table 1-1 shows the priority scheme for transmitting dynamically scheduled UL signals relative to receiving the first dynamically scheduled DL signal. Table 1-2 shows the priority scheme for transmitting dynamically scheduled UL signals relative to receiving other dynamically scheduled DL signals. Combining any one of the methods in Table 1-1 with any one of the methods in Table 1-2 constitutes a complete solution to the overlap / collision of dynamically scheduled UL signals and DL signals.

[0208] Table 1-1: Priority of Transmitting Dynamically Scheduled UL Signals Compared to Receiving the First Dynamically Scheduled DL Signal

[0209] As shown in Table 1-1, in the event that the UL signal (first UL signal or other UL signal) overlaps or collides with the first DL signal, one of the nine methods 1-1-1, 1-1-2, 1-1-3...1-1-9 can be used to resolve the conflict.

[0210] In one example, method 1-1-1: determine the priority between the UL signal and the first DL signal based on the UE implementation;

[0211] Method 1-1-2: Determine the priority between the first DL signal and the first UL signal based on the UE implementation, and that the priority of other UL signals is lower than that of the first DL signal;

[0215] Method 1-1-6: The priority of the first UL signal is lower than that of the first DL signal, and the priority of other UL signals is higher than that of the first DL signal;

[0216] Method 1-1-7: The priority of the first UL signal is higher than that of the first DL signal, and the priority between the other UL signals and the first DL signal is determined based on the UE implementation.

[0217] Method 1-1-8: The priority of the first UL signal is higher than that of the first DL signal, and the priority of other UL signals is lower than that of the first DL signal;

[0218] Method 1-1-9: The first UL signal has a higher priority than the first DL signal, and the other UL signals have a higher priority than the first DL signal.

[0219] Table 1-2: Priority of dynamically scheduled UL signals transmitted relative to other dynamically scheduled DL signals received

[0220] As shown in Table 2-1, when a UL signal (first UL signal or other UL signal) overlaps or collides with other DL signals, one of the nine methods 1-2-1, 1-2-2, 1-2-3...1-2-9 can be used to resolve the conflict.

[0221] Method 1-2-1: Determine the priority of UL signals and other DL signals based on the UE implementation;

[0222] Method 1-2-2: Determine the priority between other DL signals and the first UL signal based on the UE implementation, and the priority of other UL signals is lower than that of other DL signals;

[0223] Method 1-2-3: The priority of the first UL signal among other DL signals is determined based on the UE implementation, and the priority of other UL signals is higher than that of other DL signals;

[0224] Method 1-2-4: The priority of the first UL signal is lower than that of other DL signals, and the priority of other UL signals and other DL signals is determined based on the UE implementation.

[0225] Method 1-2-5: The priority of the first UL signal is lower than the priority of other DL signals, and the priority of other UL signals is lower than the priority of the first DL signal;

[0226] Method 1-2-6: The first UL signal has a lower priority than other DL signals, and other UL signals have a higher priority than other DL signals;

[0227] Method 1-2-7: The first UL signal has a higher priority than other DL signals, and the priority of other UL signals among other DL signals is determined based on the UE implementation.

[0228] Method 1-2-8: The first UL signal has a higher priority than other DL signals, and other UL signals have a lower priority than other DL signals;

[0229] Method 1-2-9: The first UL signal has a higher priority than other DL signals, and other UL signals have a higher priority than other DL signals.

[0230] Based on the methods in Table 1-1 and the combination of methods in Table 1-2, the following are some typical implementation schemes for solving the overlap / collision of UL signals and DL signals in dynamic scheduling.

[0231] Example 1: First UL signal vs. all DL signals; other UL signals vs. all DL signals

[0232] The first DL signal in dynamic scheduling uses the same priority rules as other DL signals; therefore, the dynamically scheduled DL signals can be considered as a whole for priority consideration. The dynamically scheduled UL signals are still divided into two categories for priority consideration: the first UL signal and other UL signals.

[0233] Methods 1-3-1 to 1-3-4 determine whether the UE should send the first UL signal / other UL signal or receive the dynamically scheduled DL signal when the first UL signal / other UL signals collide / overlap with the dynamically scheduled DL signal.

[0234] Table 1-3: Priority of Transmitting Dynamically Scheduled UL Signals Compared to Receiving Dynamically Scheduled DL Signals

[0235] 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.

[0236] Method 1-3-1 is a combination of Method 1-1-3 and Method 1-2-3 in Table 1-1 / 2.

[0237] The priority of sending other UL signals over receiving dynamically scheduled DL signals is reflected in the following: If the UE receives a first DCI sent by the network, which instructs the UE to receive a DL signal on a first resource (e.g., some symbols) (corresponding to the low-priority signal B mentioned above), and if the UE does not receive a second DCI sent by the network, which instructs the UE to send other UL signals on the first resource or at least / any part of the first resource (e.g., one symbol) (corresponding to the high-priority signal A mentioned above), then the UE receives the DL signal. Conversely, if the UE receives a second DCI sent by the network, then the UE does not receive the DL signal.

[0238] Method 1-3-2: 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 lower than the priority of receiving dynamically scheduled DL signals.

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

[0240] The lower priority of transmitting other UL signals compared to receiving dynamically scheduled DL signals is reflected in the following: If the UE receives a first DCI transmitted by the network, which instructs the UE to transmit other UL signals on the first resource (e.g., some symbols) (corresponding to the aforementioned low-priority signal B), and if the UE does not receive a second DCI transmitted by the network, which instructs the UE to receive DL signals on the first resource or at least / any part of the first resource (e.g., one symbol) (corresponding to the aforementioned high-priority signal A), then the UE transmits the other UL signals. Conversely, if the UE receives a second DCI transmitted by the network, then the UE does not transmit the other UL signals.

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

[0242] Method 1-3-3 is a combination of Method 1-1-7 / 8 and Method 1-2-7 / 8 in Table 1-1 / 2.

[0243] The higher priority of sending a first UL signal based on dynamic scheduling than receiving a DL signal based on dynamic scheduling is reflected in the following: If the UE receives a first DCI sent by the network, which instructs the UE to receive a DL signal on a first resource (e.g., some symbols) (corresponding to the low-priority signal B mentioned above), and if the UE does not receive a second DCI sent by the network, which instructs the UE to send a first UL signal on a first resource or at least / any part of the first resource (e.g., one symbol) (corresponding to the high-priority signal A mentioned above), then the UE receives the DL signal. Conversely, if the UE receives a second DCI sent by the network, then the UE does not receive the DL signal.

[0244] The priority of sending other UL signals is lower than that of receiving dynamically scheduled DL signals, which is reflected in the same way as in mode 1-3-2.

[0245] Method 1-3-4: The priority of sending the first UL signal based on dynamic scheduling is lower than the priority of receiving the DL signal based on dynamic scheduling; the priority of sending other dynamically scheduled UL signals is higher than the priority of receiving the DL signal based on dynamic scheduling, or whether to send other dynamically scheduled UL signals or receive the DL signal based on dynamic scheduling depends on the UE implementation.

[0246] Method 1-3-4 is a combination of Method 1-1-6 / 4 and Method 1-2-6 / 4 in Table 1-1 / 2.

[0247] The first UL signal in Method 1-3-4 is equivalent to the other UL signals in Method 1-3-3 above, and the other UL signals are equivalent to the first UL signal in Method 1-3-3 above.

[0248] Example 2: First DL signal vs. all UL signals; other DL signals vs. all UL signals:

[0249] The first UL signal in dynamic scheduling uses the same priority rules as other UL signals; therefore, the dynamically scheduled UL signals can be considered as a whole for priority consideration. Dynamically scheduled DL signals are still divided into two categories for priority consideration: the first DL signal and other DL signals.

[0250] Methods 1-4-1 to 1-4-4 determine whether the UE receives the first DL signal / other DL signal or sends the dynamically scheduled UL signal when the first DL signal / other DL signals collide / overlap with the dynamically scheduled UL signal.

[0251] Table 1-4: Priority of Receiving Dynamically Scheduled DL Signals Compared to Transmitting Dynamically Scheduled UL Signals

[0252] Whether to receive the first DL signal based on dynamic scheduling or send the UL signal based on dynamic scheduling in mode 1-4-1 depends on the UE implementation; receiving other dynamically scheduled DL signals has a higher priority than sending the dynamically scheduled UL signal.

[0253] Method 1-4-1 is a combination of Method 1-1-1 and Method 1-2-5 in Table 1-1 / 2.

[0254] The higher priority of receiving other dynamically scheduled DL signals than sending dynamically scheduled UL signals is reflected in the following: If the UE receives a first DCI sent by the network, which instructs the UE to send a UL signal on a first resource (e.g., some symbols) (corresponding to the low-priority signal B mentioned above), and if the UE does not receive a second DCI sent by the network, which instructs the UE to receive other DL signals on the first resource or at least / any part of the first resource (e.g., one symbol) (corresponding to the high-priority signal A mentioned above), then the UE sends the UL signal. Conversely, if the UE receives a second DCI sent by the network, then the UE does not send the UL signal.

[0255] Whether to receive the first DL signal based on dynamic scheduling or send the UL signal based on dynamic scheduling in mode 1-4-2 depends on the UE implementation; the priority of receiving other dynamically scheduled DL signals is lower than the priority of sending the dynamically scheduled UL signal.

[0256] Method 1-4-2 is a combination of Method 1-1-1 and Method 1-2-9 in Table 1-1 / 2.

[0257] The lower priority of receiving other dynamically scheduled DL signals than sending dynamically scheduled UL signals is reflected in the following: If the UE receives a first DCI sent by the network, which instructs the UE to receive other DL signals (corresponding to the low-priority signal B mentioned above) on a first resource (e.g., some symbols), and if the UE does not receive a second DCI sent by the network, which instructs the UE to send a UL signal (corresponding to the high-priority signal A mentioned above) on a first resource or at least / any part of the first resource (e.g., one symbol), then the UE receives the other DL signals. Conversely, if the UE receives a second DCI sent by the network, then the UE does not receive the other DL signals.

[0258] In method 1-4-3, the priority of receiving the first DL signal based on dynamic scheduling is higher than the priority of sending the UL signal based on dynamic scheduling; the priority of receiving other dynamically scheduled DL signals is lower than the priority of sending the UL signal based on dynamic scheduling, or whether to receive other dynamically scheduled DL signals or send the UL signal based on dynamic scheduling depends on the UE implementation.

[0259] Method 1-4-3 is a combination of Method 1-1-5 and Method 1-2-9 / 1 in Table 1-1 / 2.

[0260] The higher priority of receiving the first DL signal based on dynamic scheduling than the priority of sending the UL signal based on dynamic scheduling is reflected in the following: If the UE receives the first DCI sent by the network, which instructs the UE to send the UL signal (corresponding to the low-priority signal B mentioned above) on the first resource (e.g., some symbols), and if the UE does not receive the second DCI sent by the network, which instructs the UE to receive the first DL signal (corresponding to the high-priority signal A mentioned above) on the first resource or at least / any part of the first resource (e.g., one symbol), then the UE sends the UL signal. Conversely, if the UE receives the second DCI sent by the network, then the UE does not send the UL signal.

[0261] The priority of receiving other dynamically scheduled DL signals is lower than that of sending dynamically scheduled UL signals, which is the same as in mode 1-4-2.

[0262] In mode 1-4-4, the priority of receiving the first DL signal based on dynamic scheduling is lower than the priority of sending the UL signal based on dynamic scheduling; the priority of receiving other dynamically scheduled DL signals is higher than the priority of sending the UL signal based on dynamic scheduling, or whether to receive other dynamically scheduled DL signals or send the UL signal based on dynamic scheduling depends on the UE implementation.

[0263] Method 1-4-4 is a combination of Method 1-1-9 and Method 1-2-5 / 1 in Table 1-1 / 2.

[0264] 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.

[0265] Example 3: First DL signal vs. First UL signal; First DL signal vs. Other UL signals; First UL signal vs. Other DL signals; Other DL signals vs. Other UL signals.

[0266] When a collision occurs with a dynamically scheduled DL signal, the first dynamically scheduled UL signal uses a different priority rule than other UL signals. Furthermore, when a collision occurs with a dynamically scheduled UL signal, the first dynamically scheduled DL signal uses a different priority rule than other DL signals. Therefore, unlike Examples 1 and 2, the UL and DL signals in Example 3 cannot be considered as a single entity for priority consideration.

[0267] Based on the various combinations of methods in Tables 1-1 and 1-2, Table 1-5 lists some typical priority schemes.

[0268] Table 1-5: Priority of Transmitting Dynamically Scheduled UL Signals Compared to Receiving Dynamically Scheduled DL Signals

[0269] Method 1-5-1:

[0270] Whether to receive the first dynamically scheduled DL signal or send the dynamically scheduled UL signal (including the first UL signal and other UL signals) depends on the UE implementation;

[0271] The priority of sending the first dynamically scheduled UL signal is higher than the priority of receiving other dynamically scheduled DL signals;

[0272] Receiving other dynamically scheduled DL signals has a higher priority than sending other dynamically scheduled UL signals.

[0273] Method 1-5-2:

[0274] Whether to receive the first DL signal of dynamic scheduling or send the first UL signal of dynamic scheduling depends on the UE implementation;

[0275] The priority of sending the first dynamically scheduled UL signal is higher than the priority of receiving other dynamically scheduled DL signals;

[0276] Receiving dynamically scheduled DL signals (including the first DL signal and other DL signals) has a higher priority than sending other dynamically scheduled UL signals.

[0277] Method 1-5-3:

[0278] Whether to receive the first DL signal of dynamic scheduling or send the first UL signal of dynamic scheduling depends on the UE implementation;

[0279] The priority of receiving the first DL signal under dynamic scheduling is higher than the priority of sending other UL signals under dynamic scheduling;

[0280] The priority of sending dynamically scheduled UL signals (including the first UL signal and other UL signals) is higher than the priority of receiving other dynamically scheduled DL signals;

[0281] Method 1-5-4:

[0282] The priority of sending 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);

[0283] Whether to receive the first dynamically scheduled DL signal or send other dynamically scheduled UL signals depends on the UE implementation;

[0284] Receiving other dynamically scheduled DL signals has a higher priority than sending other dynamically scheduled UL signals.

[0285] Method 1-5-5:

[0286] The priority of sending 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);

[0287] Whether to receive the first dynamically scheduled DL signal or send other dynamically scheduled UL signals depends on the UE implementation;

[0288] The priority of transmitting other dynamically scheduled UL signals is higher than the priority of receiving other dynamically scheduled DL signals;

[0289] Methods 1-5-6:

[0290] The priority of receiving the first DL signal under dynamic scheduling is higher than the priority of sending the UL signal under dynamic scheduling (including the first UL signal and other UL signals);

[0291] The priority of sending the first dynamically scheduled UL signal is higher than the priority of receiving other dynamically scheduled DL signals;

[0292] Receiving other dynamically scheduled DL signals has a higher priority than sending other dynamically scheduled UL signals.

[0293] Methods 1-5-7:

[0294] Whether to receive the first dynamically scheduled DL signal or send the dynamically scheduled UL signal (including the first UL signal and other UL signals) depends on the UE implementation;

[0295] The priority of sending dynamically scheduled UL signals (including the first UL signal and other UL signals) is higher than the priority of receiving other dynamically scheduled DL signals.

[0296] Example 4:

[0297] As mentioned above, combining any one of the methods in Table 1-1 with any one of the methods in Table 1-2 constitutes a solution to the overlap / collision of UL signals and DL signals in dynamic scheduling. Some solutions formed by combining some methods in Table 1-1 with some methods in Table 1-2 are shown in Examples 1, 2, and 3.

[0298] When the received dynamically scheduled DL signal overlaps / collides with the transmitted dynamically scheduled UL signal, the default priority is a combination of any one of the methods in Table 1-1 and any one of the methods in Table 1-2.

[0299] In Example 4, the network is further allowed to rewrite the default priorities mentioned above via signaling. For example, the network can configure or indicate the priority between receiving dynamically scheduled DL signals and transmitting dynamically scheduled UL signals via 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.

[0300] Method 1: The priority signaling configuration / indication issued by the network applies to all dynamically scheduled DL signals and all dynamically scheduled UL signals.

[0301] For example, if the network configuration prioritizes receiving DL signals over transmitting UL signals, then receiving all dynamically scheduled DL signals has a higher priority than transmitting all dynamically scheduled UL signals. Here, "all DL signals" includes the first DL signal and all other DL signals, and "all UL signals" includes the first UL signal and all other UL signals. The reverse is also true.

[0302] Method 2: The priority signaling configuration / indication issued by the network only applies to collisions / overlaps between other DL signals (excluding the first DL signal) and all UL signals.

[0303] For example, in mode 1-4-1: "Whether to receive the first DL signal based on dynamic scheduling or to 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 the dynamically scheduled UL signal." The above is the default transmission priority. If the network configuration / indication states that the priority of receiving DL signals is higher than that of sending UL signals, then both priorities in mode 1-4-1 remain unchanged. If the network configuration / indication states that the priority of receiving DL signals is lower than that of sending UL signals, then the first priority in mode 1-4-1 remains unchanged, while the second priority is rewritten.

[0304] Method 3: The priority signaling configuration / indication issued by the network only applies to collisions / overlaps between UL signals other than the first UL signal and all DL signals.

[0305] For example, in mode 1-3-1: "Whether to send a first UL signal based on dynamic scheduling or receive a 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 dynamically scheduled DL signals." The above is the default transmission priority. If the network configuration / indication states that the priority of sending UL signals is higher than that of receiving DL signals, then both priorities in mode 1-3-1 remain unchanged. If the network configuration / indication states that the priority of sending UL signals is lower than that of receiving DL signals, then the first priority in mode 1-3-1 remains unchanged, while the second priority is rewritten.

[0306] Method 4: The priority signaling configuration / indication issued by the network only applies to collisions / overlaps between DL signals other than the first DL signal and UL signals other than the first UL signal.

[0307] For example, in mode 1-5-1: "Whether to receive the dynamically scheduled first 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 dynamically scheduled first 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 is the default transmission priority. If the network configuration / indication is that the priority of receiving DL signals is higher than that of transmitting UL signals, then all three priorities in mode 1-5-1 remain unchanged. If the network configuration / indication is that the priority of receiving DL signals is lower than that of transmitting UL signals, then the first / second priorities in mode 1-5-1 remain unchanged, while the third priority is rewritten.

[0308] For example, in mode 1-5-4: "The priority of sending the dynamically scheduled first 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 dynamically scheduled first DL signal or send 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 sending other dynamically scheduled UL signals." The above is the default transmission priority. If the network configuration / priority indication signaling states that the priority of receiving DL signals is higher than that of sending UL signals, then all three priorities in mode 1-5-4 remain unchanged. If the network configuration / priority indication signaling states that the priority of receiving DL signals is lower than that of sending UL signals, then the first / second priorities in mode 1-5-4 remain unchanged, while the third priority is rewritten.

[0309] For example, in Mode 1-4-2 / Mode 1-5-7: whether to receive the first dynamically scheduled DL signal or send 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 sending dynamically scheduled UL signals (including the first UL signal and other UL signals). The above is the default transmission priority. If the network configuration / priority indication signaling states that the priority of receiving DL signals is lower than that of sending UL signals, then both priority rules in Mode 1-4-2 / Mode 1-5-7 remain unchanged. If the network configuration / priority indication signaling states that the priority of receiving DL signals is higher than that of sending UL signals, then the first priority rule in Mode 1-4-2 / Mode 1-5-7 remains unchanged, while the second rule, "the priority of receiving other dynamically scheduled DL signals is lower than that of sending other dynamically scheduled UL signals," is rewritten.

[0310] Method 5: The priority signaling issued by the network configures / indicates a priority reversal. When the network configures / indicates the above priority signaling or the UE detects the above priority signaling, one or more combinations of methods 5-1 to 5-5 are executed (e.g., method 5-1 combined with other methods). If the network does not configure / indicate the above priority signaling or the UE does not detect the above priority signaling, the default transmission priority remains unchanged.

[0311] Method 5-1: Flip / rewrite the default transmission priority from "high" to "low" (i.e., flip the priority of a high-priority uplink or downlink signal to low priority), and / or flip / rewrite the "low" priority to "high" (i.e., flip the priority of a low-priority uplink or downlink signal to high priority), and / or, if the priority depends on the "UE implementation", do not flip / rewrite (i.e., do not flip the priority if the priority of the uplink and downlink signals depends on the UE implementation).

[0312] Method 5-2: Flip the priority to flip the default transmission priority for collisions / overlaps between all DL signals and all UL signals.

[0313] Method 5-3: The priority flipping only applies to the default transmission priority where collisions / overlaps occur between other DL signals (excluding the first DL signal) and all UL signals.

[0314] Method 5-4: Flipping priority only applies to the default transmission priority that collides / overlaps with all DL signals except the first UL signal.

[0315] Method 5-5: The priority flipping only applies to the default transmission priority when there is a collision / overlap between DL signals other than the first DL signal and UL signals other than the first UL signal.

[0316] Example 2

[0317] For situations where resource collisions / overlaps occur between semi-static DL signal reception and semi-static UL signal transmission:

[0318] For UEs of HD-FDD or TDD types, when the semi-static DL signal reception and semi-static UL signal transmission collide / overlap, the solution in Embodiment 1 can also be used. The solution in Embodiment 1 only needs to be modified in the following places to be adopted.

[0319] 1. Replace "dynamic scheduling" in Implementation Example 1 with "semi-static configuration";

[0320] 2. Modify the DL signal / first DL signal / other DL signals and UL signal / first UL signal / other UL signals in Example 1 to:

[0321] DL signals include at least one of the following: PDCCH CSS sets with 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;

[0322] The first DL signal includes one or more DL signals (e.g., a set of PDCCH CSS signals with different types such as Type-0 / 0A / 1 / 2). Other DL signals include one or more DL signals other than the first DL signal.

[0323] UL signals include at least one of the following: (based on configuration authorization) PUSCH, (SP / P-)SRS, PUCCH, PRACH.

[0324] The first UL signal includes one or more of the UL signals (e.g., a PUCCH carrying HARQ-ACK / SR / CSI). Other UL signals include one or more UL signals other than the first UL signal.

[0325] Similarly, combining any one of the methods in Table 1-1 with any one of the methods in Table 1-2 constitutes a complete solution to the overlap / collision between the semi-static DL signal and the semi-static UL signal.

[0326] When resource collisions / overlaps occur between semi-static DL signal reception and semi-static UL signal transmission, different solutions can be adopted for UEs in different states.

[0327] For example, if the UE is in RRC connected state (RRC_CONNECTED), the scheme in method 1-4-1 can be used. That is, whether to receive the first DL signal of the semi-static configuration (such as the PDCCH configured with the common search space set of Type-0 / 0A / 1 / 2-PDCCH) or send the UL signal of the semi-static configuration depends on the UE implementation; the priority of receiving other DL signals of the semi-static configuration is higher than the priority of sending the UL signal of the semi-static configuration by default. If the UE is in RRC deactivated state (RRC_INACTIVE), a combination of methods 1-1-1 and 1-2-1 can be used. That is, whether to receive the DL signal of the semi-static configuration (such as the PDCCH configured with the common search space set of Type-0 / 0A / 0B / 1 / 2-PDCCH) or send the UL signal of the semi-static configuration depends on the UE implementation; either by default, the UE receives the DL signal of the semi-static configuration (without sending the UL signal), or by default, it sends the UL signal of the semi-static configuration (without receiving the DL signal).

[0328] Example 3

[0329] For situations where resources collide or overlap between one / multiple DL transmissions and one / multiple UL transmissions:

[0330] This embodiment addresses the resource collision / overlap issue between one / multiple DL transmissions and one / multiple UL transmissions. One DL transmission or one UL transmission may include receiving one DL signal or transmitting one UL signal. "One" can also be equivalent to "one".

[0331] The resource collisions / overlaps between one / multiple DL transmissions and one / multiple UL transmissions mentioned above can include the following three situations: resource collisions / overlaps between one DL transmission and multiple UL transmissions; resource collisions / overlaps between one UL transmission and multiple DL transmissions; and resource collisions / overlaps between multiple DL transmissions and multiple UL transmissions. The above three types of resource collisions / overlaps can be resolved by a combination of at least one or more of the following methods.

[0332] Method 1: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, if one / multiple DL transmissions include the first DL signal, they will be processed according to the priority handling method for resource collisions / overlaps between the first DL signal and the UL signal.

[0333] Taking the collision / overlap of a semi-static DL signal and a semi-static UL signal in Embodiment 2 as an example, assuming the first DL signal is a PDCCH with Type 0 / 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 send the UL signal depends on the UE implementation; the priority of receiving other DL signals is higher than the priority of sending the UL signal by default, but the priority of other DL signals and UL signals can be rewritten through network configuration. Figure 4 is a schematic diagram of a collision or overlap of a semi-static DL signal and a semi-static UL signal provided in an embodiment of this application. Based on this example, as shown in Figure 4, when two DL signals collide / overlap with one UL signal, regardless of whether the first DL signal comes first or last, it is uniformly processed according to the method of resource collision / overlap of the first DL signal and the UL signal. That is, in this example, whether to receive the first DL signal / other DL signals or send the UL signal is determined by the UE implementation.

[0334] Method 2: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, if one / multiple UL transmissions include the first UL signal, they will be processed according to the priority handling method of resource collision / overlap between the first UL signal and the DL signal.

[0335] Taking Example 1, Mode 1-3-3 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 sending the first UL signal is higher than the priority of receiving the DL signal; the priority of sending other UL signals is lower than the priority of receiving the DL signal, or, whether to send other UL signals or receive the DL signal depends on the UE implementation. Figure 5 is a schematic diagram of a collision or overlap between dynamically scheduled DL signals and dynamically scheduled UL signals provided in an embodiment of this application. Based on this example, as shown in Figure 5, when two UL signals collide / overlap with one DL signal, regardless of whether the first UL signal comes first or last, it is uniformly processed according to the method of resource collision / overlap between the first UL signal and the DL signal. That is, in this example, the priority of sending the first UL signal and other UL signals is higher than that of receiving the DL signal.

[0336] Method 3: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, if one / multiple DL transmissions include the first DL signal and if one / multiple UL transmissions include the first UL signal, then they are processed according to the priority of resource collision / overlap between the first DL signal and the first UL signal.

[0337] Taking Example 3, Mode 1-5-1 of Embodiment 1 as an example, when the first DL signal / other DL signals collide / overlap with the first UL signal / other UL signals, the priority rule adopted is: whether to receive the dynamically scheduled first DL signal or send the dynamically scheduled UL signal (including the first UL signal and other UL signals) depends on the UE implementation; the priority of sending 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 sending the dynamically scheduled other UL signals.

[0338] Figure 6 is a schematic diagram illustrating another collision or overlap between dynamically scheduled DL signals and dynamically scheduled UL signals provided in an embodiment of this application. Based on this example, as shown in Figure 6, when two UL signals collide / overlap with two DL signals, regardless of whether the first DL signal and the first UL signal are in the first or second position in the time domain, they are uniformly processed as resource collisions / overlaps between the first DL signal and the first UL signal. That is, in this example, whether to receive a DL signal or send a UL signal is determined by the UE.

[0339] If we take Example 3, Method 1-5-4 of Embodiment 1 as an example, then when two UL signals collide / overlap with two DL signals, the priority of sending the UL signal is higher than the priority of receiving the DL signal.

[0340] Method 4: When one or more DL transmissions collide or overlap with one or more UL transmissions, they are handled in the same way as the first DL transmission and the first UL transmission.

[0341] For example, in the example in Figure 4(a), all signals are uniformly processed in the manner of collision / overlap between the first DL signal and the UL signal resources in the semi-static configuration, that is, all are determined by the UE implementation; in the example in Figure 4(b), all signals are uniformly processed in the manner of collision / overlap between the other DL signals and the UL signal resources in the semi-static configuration, that is, the priority of receiving DL signals is higher than the priority of UL signals, or it is determined by the network configuration.

[0342] For example, in the example of Figure 5(a), all signals are uniformly processed in the manner of collision / overlap between the dynamically scheduled first UL signal and the dynamically scheduled DL signal resources, that is, the priority of sending UL signals is higher than that of receiving DL signals; in the example of Figure 5(b), all signals are uniformly processed in the manner of collision / overlap between the dynamically scheduled other UL signals and the dynamically scheduled DL signal resources, that is, the priority of sending UL signals is lower than that of receiving DL signals, or it depends on the UE implementation.

[0343] For example, in the example of Figure 6(a), all signals are uniformly processed according to the collision / overlap of the first dynamically scheduled DL signal and the first dynamically scheduled UL signal resources, which depends on the UE implementation; in the example of Figure 6(b), all signals are uniformly processed according to the collision / overlap of other dynamically scheduled DL signals and other dynamically scheduled UL signal resources, which means that the priority of receiving DL signals is higher than the priority of UL signals.

[0344] Method 5: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, if a DL transmission within the one / multiple DL transmissions has a higher priority, then all DL transmissions are received and all UL transmissions are cancelled. For example, if the DL transmissions contain dynamically scheduled signals, and the UL transmissions are all semi-statically configured signals.

[0345] Method 6: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, if a UL transmission within the one / multiple UL transmissions has a higher priority, then all UL transmissions are received and all DL transmissions are cancelled. For example, if the UL transmissions contain dynamically scheduled signals, and the DL transmissions are all semi-statically configured signals.

[0346] Method 7: When one or more DL transmissions collide or overlap with one or more UL transmissions, resolve the collisions of each DL transmission and UL transmission in chronological order.

[0347] Method 8: When one / multiple DL transmissions collide / overlap with one / multiple UL transmissions, it depends on the UE implementation; or when multiple transmissions with overlapping resources include the first DL signal and / or the first UL signal, whether to receive the DL signal or send the UL signal depends on the UE implementation.

[0348] Example 4

[0349] For situations where NTN and another function coexist in-device (IDC):

[0350] To allow users ubiquitous access to various networks and services, an increasing number of user-defined devices (UEs) are equipped with multiple radio transceivers. For example, a single UE may be equipped with NR / LTE, WiFi, and Bluetooth transceivers, as well as Global Navigation Satellite System (GNSS) receivers (such as GPS, Galileo, GLONASS, BeiDou Navigation Satellite System, etc.). Due to the extreme proximity of multiple radio transceivers within the same UE operating on adjacent frequencies or subharmonic frequencies, the interference power from shared radio transmitters can be far higher than the actual received signal power level required by the receiver. This situation leads to IDC interference, known as the IDC problem.

[0351] Figure 7 is a schematic diagram of an IDC interference scenario provided by related technologies. As shown in Figure 7, the radio transceiver with NTN function within the same UE also suffers from IDC interference problems with other functional receivers. For example, when an adjacent frequency band is transmitting NTN uplink (UL) signals, it will cause significant interference to the GNSS receiver, making it impossible to guarantee simultaneous NTN transmission and GNSS reception.

[0352] Therefore, existing IDC functions and solutions need to be improved to solve the IDC interference problem between NTN transmission and other transmissions (including GNSS, Bluetooth (BT), Wireless Fidelity (WiFi), New Radio (NR) (e.g., NR-U) / LTE (e.g., LAA) / others, etc., with GNSS as an example in the following solutions).

[0353] If IDC interference occurs when NTN (e.g., the UE transmits an NTN UL signal) and another party (e.g., the UE receives a GNSS signal) are transmitting simultaneously, it can be resolved by any one or a combination of the following solutions.

[0354] Option 1: Introduce a new UE capability for NTN UEs. This capability indicates whether the UE supports IDC auxiliary information, which includes at least auxiliary information about IDCs between the NTN and another party (e.g., GNSS). One or more pieces of this IDC auxiliary information can be reported by the UE to the network or configured by the network to the UE to help resolve IDC interference issues.

[0355] Optionally, the NTN UE reports / indicates the above-mentioned UE capabilities to the network.

[0356] Optionally, the network may indicate whether the UE is permitted to send IDC indications via Radio Resource Control (RRC) signaling (e.g., dedicated RRC signaling), MAC CE, or DCI signaling.

[0357] Option 2: The UE reports IDC information (or the aforementioned IDC auxiliary information) to the network.

[0358] Optionally, the UE is a UE with the new UE capabilities in Scheme 1, that is, the UE supports auxiliary information of IDC between NTN and the other party.

[0359] Optionally, the UE can report NTN-related IDC information to the network only after the network indicates that the UE is allowed to send IDC instructions. Alternatively, after the network indicates that the UE is allowed to send IDC instructions, if the UE has not yet reported IDC information or the IDC information has changed due to a detected IDC problem, the UE will report the IDC information to the network.

[0360] The reported IDC information includes at least one of the following:

[0361] Frequency domain information:

[0362] - A list of NTN / GNSS frequency domain information or frequency domain information that has been subjected to or is subjected to IDC interference, and / or a list of frequency domain information or frequency domain information that enables GNSS / NTN to be used with FDM schemes;

[0363] - Frequency domain information includes at least one of the following: frequency range (e.g., start and end frequencies, start frequency and bandwidth, or center frequency and bandwidth), carrier / band, carrier / band frequency, carrier / band frequency range, carrier / band group, carrier / band combination, carrier / band frequency range combination, subband, resource element / resource block, bandwidth part (BWP), passband, cell, etc.

[0364] Interference scenarios:

[0365] - Interference scenarios include at least one or more of the following combinations: IDC interference direction, IDC interference source, IDC interfered party (victim), IDC interference source / interferenced party type, or frequency domain information of the interference or a list of frequency domain information (as above);

[0366] - For example, the direction of IDC interference / the party being interfered with can include the following situations: only NTN is the party being interfered with, only the other party (e.g., GNSS) is the party being interfered with, and both NTN and the other party are the parties being interfered with;

[0367] - For example, the interference scenario is: NTN band X / Y / Z / ... interfering with GNSS reception. The IDC interference source is NTN band X / Y / Z / ..., and the object of interference is GNSS. Different interference scenarios can be numbered, and the UE sends the interference scenario number to the network.

[0368] - IDC interference source / interferenced entity type is a further subdivision of IDC interference source / interferenced entity. For example, the IDC interferenced entity type can be one or more of the following: GNSS type 1, GNSS type 2, ..., GNSS type X, Bluetooth, WiFi, LTE, NR, NTN, etc.

[0369] • Time domain information:

[0370] - Time-domain information that enables GNSS / NTN to be used with Time-Division Multiplexing (TDM) schemes, or Discontinuous Reception (DRX) configuration information (or parameter information required for network DRX configuration), including at least one of the following: period, offset (which can be further subdivided into multiple offsets, including: first-granularity offset (e.g., ms / slot level offset), second-granularity offset (e.g., slot / symbol level offset), etc.), and duration of activation;

[0371] - and / or, timing advance (units are X ms / µs / ns or Y subframe / slot / symbol or Z basic time units, where X, Y, and Z are decimals or integers, e.g., X = 0.5 ms or 1 ms, Y = 0.5 slot or 1 slot, or Z = 16·64·T c / 2 μ Subframes / slots / symbols can be associated with fixed or variable subcarrier intervals. Tc is the basic time unit defined in NR, or the drift rate of timing advance.

[0372] - and / or, GNSS time-domain resource information, NTN transmission time-domain resource information, and NTN / GNSS time-domain resource overlap information;

[0373] Other information includes at least one of the following: power information of NTN transmission, measurement information (e.g., reported measurement results related to UE IDC), presence / absence of IDC interference, cause of IDC interference (hardware sharing, out-of-band leakage, co-channel interference, or excessive or higher-than-threshold transmit power), UE location, etc.

[0374] The UE can send IDC information to the network in the UE auxiliary message reported by the UE to the network.

[0375] Option 3: Configure an IDC solution for the UE via the network. This may include at least one of the following options:

[0376] • Time-domain scheme. For example, NTN and another party adopt a TDM / DRX scheme. The configuration information of this scheme includes: period, offset (which can be further subdivided into multiple offsets, including: first-granularity offset (e.g., ms / slot level offset), second-granularity offset (e.g., slot / symbol level offset) etc.), duration of activation, and / or TDM pattern.

[0377] • Frequency domain scheme. For example, an NTN and another party using an FDM scheme. This involves switching / assigning one party (e.g., NTN transmission) to another target frequency domain resource, or activating / deactivating operations on a target frequency domain resource. The configuration information for this scheme includes frequency domain information configuring the target frequency domain resource. This frequency domain information includes at least one of the following: frequency range (e.g., start and end frequencies, start frequency and bandwidth, or center frequency and bandwidth), carrier / band, carrier / band frequency, carrier / band frequency range, carrier / band group, carrier / band combination, carrier / band frequency range combination, subband, resource element / resource block, partial bandwidth (BWP), passband, cell, etc.

[0378] • Other solutions. For example, the network configures the UE with the maximum transmit power of the NTN or another party, a power leakage threshold, or an interference threshold. When the UE's transmit power exceeds the aforementioned maximum transmit power or threshold, an IDC interference solution needs to be implemented. Another example is a solution implemented through network scheduling to address the IDC problem.

[0379] The network can configure / instruct the UE on the IDC solution via RRC signaling (e.g., dedicated RRC signaling), MAC CE, or DCI signaling.

[0380] Option 4: The UE cancels the transmission of one party on its own.

[0381] Option 4-1: Based on network configuration, the UE can cancel NTN transmission (e.g., send NTN uplink signal) to protect the other party's transmission (e.g., receive GNSS signal).

[0382] The network configures the probability of canceling NTN transmissions within a certain duration / over a long period through signaling (e.g., dedicated RRC signaling) to limit the number of voluntary NTN transmission cancellations. Once the network configuration is obtained, the UE can cancel NTN transmissions voluntarily. Otherwise, the UE is not allowed to cancel any NTN transmissions voluntarily.

[0383] In this scheme, as long as the specific restrictions / requirements of the network configuration are met, the UE can decide which NTN transmission to cancel.

[0384] Option 4-2: Based on UE autonomous decision-making, the UE can cancel NTN transmission on its own to protect the other party's transmission. This option is not subject to network configuration constraints.

[0385] In this scheme, without any restrictions from the network side, the UE can decide which NTN transmission to cancel.

[0386] Option 4-3: Based on network configuration, the UE can cancel the transmission of another party (e.g., receiving GNSS signals) to ensure connection with 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.

[0387] The network configures the probability of canceling GNSS transmissions within a certain duration / over a long period through signaling (e.g., dedicated RRC signaling) to limit the number of voluntary GNSS transmission cancellations. Once the network configuration is obtained, the UE can cancel GNSS transmissions voluntarily. Otherwise, the UE is not allowed to cancel any GNSS transmissions voluntarily.

[0388] In this scheme, as long as the specific restrictions / requirements of the network configuration are met, the UE can decide which GNSS reception to cancel.

[0389] Option 4-4: Based on UE autonomous decision-making, the UE can cancel the transmission of another party (e.g., receiving GNSS signals) to ensure connection with 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 option is not constrained by network configuration.

[0390] In this scheme, without any restrictions from the network side, the UE can decide which GNSS reception to cancel.

[0391] For schemes 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 portions of transmissions overlapping with GNSS time-domain resources, single transmissions overlapping with GNSS time-domain resources, overlapping portions of single transmissions overlapping with GNSS time-domain resources, all transmissions overlapping with GNSS time-domain resources, and all duplicate transmissions related to transmissions overlapping with GNSS time-domain resources. Cancelled GNSS transmissions can be handled using similar methods, such as transmissions overlapping with NTN transmission time-domain resources, overlapping portions of transmissions overlapping with NTN transmission time-domain resources, etc. The type of cancelled NTN / GNSS transmission can also be determined based on network configuration; that is, the network configures which type of NTN transmission is being cancelled.

[0392] In this application, the timing for the UE to execute the IDC scheme can be at least one of the following:

[0393] Option 5-1: The UE executes the IDC scheme based on the latest timing from the UE side, that is, it executes the above IDC scheme based on the latest TA obtained from the UE side.

[0394] Option 5-2: The UE executes the IDC scheme based on the last / most recent TA reported to the network, that is, it executes the above scheme based on the timing of the UE side as determined by the base station.

[0395] Scheme 5-3: The UE performs the above scheme on time domain resources where NTN transmission (e.g., NTN UL) and the other party's transmission overlap, based on the timing of the latest TA reported by the UE and the timing of the last / most recent TA reported to the network.

[0396] For example, if the timing is based on the latest TA reported by the UE, the NTN UL transmission and GNSS reception overlap in time period T1. If the timing is based on the last / most recent TA reported by the UE to the network, the NTN UL transmission and GNSS reception overlap in time period T2. For scheme 5-1, the UE executes scheme four or other schemes only in time period T1. For scheme 5-2, the UE executes scheme four or other schemes only in time period T2. For scheme 5-3, the UE executes scheme four or other schemes in both time periods T1 and T2.
