Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method, terminal, and device for transmitting uplink control information (UCI) on the Physical Uplink Shared Channel (PUSCH). Background Technology

[0002] In 5G NR (5Generation New Radio), uplink channel transmission with different physical layer priorities is supported. Resource conflicts may occur between uplink channels with different physical layer priorities on the same UE, such as overlapping symbols occupied by uplink channels with different priorities on the same carrier. In Rel-16, only the channel with the higher physical layer priority among conflicting channels is transmitted, and the channel with the lower physical layer priority is discarded. In Rel-17, to avoid discarding uplink control information (UCI) carried on low-priority channels, multiplexing transmission of uplink channels with different physical layer priorities can be considered.

[0003] When uplink channels with different physical layer priorities overlap in the time domain, and multiplexing transmission of uplink channels with different priorities is supported, there may be multiple Physical Uplink Shared Channels (PUSCHs) with different priorities and one Physical Uplink Control Channel (PUCCH) that overlap in the time domain at the same time. In this case, there is no clear method for how to select one PUSCH from multiple PUSCHs with different priorities to carry UCI on the PUCCH. Summary of the Invention

[0004] This invention provides a method, terminal, and network-side device for transmitting UCI on a PUSCH, which solves the problem of how to select one PUSCH to carry UCI on the PUCCH when multiple PUSCHs with different priorities overlap with a PUCCH in the time domain.

[0005] In a first aspect, an embodiment of the present invention provides a method for transmitting UCI on a PUSCH, comprising:

[0006] It was determined that the PUCCH carrying UCI has temporal resource overlap with multiple PUSCHs of different physical layer priorities;

[0007] Select one PUSCH from the plurality of PUSCHs according to a predetermined selection rule, or select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH;

[0008] The UCI is transmitted via the selected PUSCH.

[0009] This invention provides two methods for selecting a PUSCH to carry UCI on a PUCCH. One method selects a PUSCH from multiple PUSCHs according to a predetermined selection rule, and the other method selects a PUSCH with the same physical layer priority as the PUCCH from multiple PUSCHs. This solves the problem of how to select a PUSCH to transmit the UCI carried by the PUCCH when there is temporal resource overlap between the PUCCH and multiple PUSCHs with different physical layer priorities. This embodiment is applied to a terminal. After selecting a PUSCH to transmit the UCI carried by the PUCCH using the above two methods, the UCI is transmitted through the selected PUSCH.

[0010] As an optional implementation, the step of selecting a PUSCH from the plurality of PUSCHs according to a predetermined selection rule, or selecting a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH, includes:

[0011] If the PUCCH has a high priority, then select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH;

[0148] In 5G NR, uplink channel transmission with different physical layer priorities is supported. Resource conflicts may occur between uplink channels with different physical layer priorities on the same UE. For example, on the same carrier, there may be overlap in the symbols occupied by uplink channels with different priorities. In Rel-16, only the channel with the higher physical layer priority among the conflicting channels is transmitted, and the channel with the lower physical layer priority is discarded. In Rel-17, to avoid discarding UCIs carried on low-priority channels, it is possible to consider supporting multiplexing transmission of uplink channels with different physical layer priorities, that is, transmitting information of different priorities simultaneously on the same uplink channel. However, there is currently no specific multiplexing transmission method.

[0149] 1) This embodiment describes the channel transmission with different physical layer priorities in the prior art:

[0150] A single UE can support different service types, such as enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC). Different service types have different requirements for reliability and transmission latency. URLLC service flows may occur sporadically and intermittently; therefore, reserving separate system resources for different services results in significant overhead on system resources, and the resources reserved for URLLC may often remain unused. To improve system resource utilization, different services can be allowed to multiplex transmissions on the same resources. However, this may lead to a situation where a data transmission scheduled earlier is interrupted or canceled by a data transmission scheduled later. For example, after a UE is scheduled to transmit an eMBB service on resource 1, if a URLLC service arrives and needs to be scheduled as soon as possible to meet the latency requirements of the URLLC service, it may occupy all or part of the resources (including time domain resources and / or frequency domain resources) in resource 1 that have already been allocated to the eMBB service for URLLC transmission. For example, URLLC transmission may be scheduled on all or part of the symbols in the time domain resources (symbol set) scheduled for eMBB on the same carrier, regardless of whether the frequency domain resources overlap. Since two uplink channels cannot be transmitted simultaneously on the same carrier at the same time, the eMBB service will be interrupted or canceled by the URLLC service.

[0151] To avoid interference between services, different priorities can be defined for different services. When resource conflicts occur, the higher-priority channel is selected for transmission, and the lower-priority channel is discarded. Therefore, to better support the transmission of different services with varying needs, Rel-16 introduced physical layer priorities. It stipulates that when channels with different physical layer priorities conflict—that is, when multiple PUCCHs overlap in the time domain on the same carrier, or when PUCCHs and PUSCHs overlap in the time domain on the same carrier—the lower-priority channel is discarded, and only the higher-priority channel is transmitted.

[0152] The physical layer priority of PUCCH and PUSCH can be obtained through default method, dynamic indication by downlink control information (DCI), or semi-static configuration by radio resource control (RRC). For example, when PUCCH carries a Scheduling Request (SR), its priority is determined by the priority of the SR it carries, and the priority of each SR configuration is configured by the higher-layer signaling. When PUCCH carries a Hybrid Automatic Repeat Request-ACK (HARQ-ACK) for SPS PDSCH, or a HARQ-ACK for the Physical Downlink Control Channel (PDCCH) indicating the release of SPS resources (i.e., SPS PDSCH release), its priority is determined by the HARQ-ACK codebook number configured for the SPS PDSCH by the higher-layer signaling. The HARQ-ACK codebook with number 0 has low priority, and the HARQ-ACK codebook with number 1 has high priority. When PUCCH carries CSI (including periodic CSI and SP-CSI), its priority is low by default. When a priority indication field is included in the DCI, the priority can be obtained through the priority indication field in the DCI (or PDCCH, in this invention PDCCH and DCI can be considered equivalent, DCI is the specific format used for PDCCH transmission, so having the corresponding DCI is equivalent to having the corresponding PDCCH) of PUCCH and PUSCH. For example, if the DCI used by PDCCH includes a priority indication field, then: when PDCCH schedules a PDSCH, the priority of the PUCCH carrying the HARQ-ACK of this PDSCH can be indicated through the priority indication field; when PDCCH schedules a PUSCH, the priority of the scheduled PUSCH can be indicated through the priority indication field. Here, PUSCH includes PUSCH that only carries a Transport Block (TB), or PUSCH that only carries A-CSI, or PUSCH that carries both TB and A-CSI; for PUSCH carrying SP-CSI, its priority can be obtained by activating the priority indication field in the DCI of the PUSCH carrying SP-CSI. If the DCI does not contain a priority indication field, or if the higher-level signaling does not have a priority configured, the default priority is low.

[0153] 2) This embodiment describes the UCI transmission in 5G NR using existing technologies:

[0154] UCI includes HARQ-ACK, Channel State Information (CSI), and SR. UCI is transmitted on PUCCH. HARQ-ACK is a collective term for positive acknowledgment (ACK) and negative acknowledgment (NACK), used to provide feedback on PDSCH or PDCCH indicating the release of semi-persistent scheduling (SPS) resources (also known as SPS PDSCH release), informing the base station whether the PDSCH or the PDCCH indicating the release of SPS PDSCH has been correctly received. CSI is used to provide feedback on downlink channel quality, thereby helping the base station to better perform downlink scheduling, such as selecting Modulation and Coding Scheme (MCS) and configuring appropriate Resource Block (RB) resources based on CSI. SR is used when a terminal needs to transmit uplink services, requesting transmission resources for the PUSCH carrying the uplink service from the base station.

[0155] 3) This embodiment explains the temporal resource overlap between PUCCH and PUCCH / PUSCH of the same priority in the prior art:

[0156] NR R15 and R16 do not support parallel transmission of PUCCH and PUSCH at the same time, regardless of whether they are on the same carrier or different carriers. When PUCCH and PUSCH (unless otherwise specified, PUCCH and PUSCH generally refer to PUCCH and PUSCH that do not use duplicate transmission) overlap in time domain resources, under the condition of satisfying predetermined timeline, UCI (usually HARQ-ACK and CSI) can be transferred from PUCCH to a PUSCH for transmission. If SR (positive SR) exists, the SR will not be transmitted on the PUSCH and will be discarded. If multiple PUSCHs overlap with a PUCCH, a PUSCH is selected according to predetermined rules. Among these rules, the PUSCH carrying A-CSI is given priority. If there are both PUSCHs with PDCCH scheduling (DG PUSCH) and PUSCHs without PDCCH scheduling (CG PUSCH, SP-CSI PUSCH, etc.), the DG PUSCH is given priority. After selection according to the above rules, if there are PUSCHs on multiple carriers, the PUSCH on the carrier with the lower carrier number is given priority. If multiple PUSCHs that do not overlap in the time domain overlap with a PUCCH on the selected carrier, the earliest PUSCH is selected.

[0157] It should be noted that the above timeline is defined as follows: If a PUCCH or PUSCH has a corresponding PDCCH, for example, if the HARQ-ACK carried by the PUCCH is the HARQ-ACK of a PDSCH with PDCCH scheduling or the HARQ-ACK of a PDCCH indicating the release of downlink SPS resources, then the PDCCH that schedules the PDSCH or the PDCCH indicating the release of downlink SPS resources is the PDCCH corresponding to the PUCCH, or it can also be called the PDCCH that schedules the PUCCH. The PDCCH that schedules the PUSCH is the PDCCH corresponding to the PUSCH. The first symbol of the channel with the earliest start time among the overlapping PUCCH and PUSCH is taken as the target symbol. If there are multiple channels with the same start time, then any channel is randomly selected, and its first symbol is taken as the target symbol. The target symbol must meet the following timeline to be multiplexed and transmitted; otherwise, it is considered an incorrect scheduling:

[0158] Timeline 1: The target symbol is no earlier than the first symbol after the T1mux time following the last symbol of any PDSCH or SPS PDSCH release that requires HARQ-ACK feedback on the PUCCH (including the Cyclic Prefix (CP)).

[0159] That is, the time interval between the target symbol and the last symbol of any of the aforementioned PDSCH or SPS PDSCH releases shall not be less than T1mux. T1mux is related to the PDSCH processing delay and can be calculated according to a predetermined formula and related parameters. The purpose of this timeline is to ensure that the acquisition and preparation of HARQ-ACK can be completed before the transmission of the finally determined channel for HARQ-ACK transmission begins.

[0160] Timeline 2: The target symbol is no earlier than the first symbol after the T2mux time following the last symbol of either the scheduling PDSCH (if any) or PUSCH (if any) (including the PDCCH indicating the release of the SPS PDSCH).

[0161] That is, the time interval between the target symbol and the last symbol of any of the above PDCCHs shall not be less than T2mux time. T2mux is related to the processing delay of PUSCH and can be calculated according to a predetermined formula and related parameters. The purpose of this timeline 2 is to ensure that when UCI needs to be transferred to PUSCH for transmission, the PDCCH scheduling PUSCH can be obtained before the PUCCH preparation begins, thereby determining that UCI transmission does not need to be prepared on PUCCH, and that transmission preparation, including UCI, can be completed before PUSCH transmission, that is, UCI acquisition and multiplexing processing, and TB preparation (such as encoding, modulation, scrambling, etc.) are completed. If it is multiplexing between multiple PUCCHs, T2mux can also be used to simulate the preparation time of CSI and SR and HARQ-ACK multiplexing.

[0162] If the HARQ-ACK carried by the PUCCH does not have a corresponding PDCCH (i.e., the HARQ-ACK is the HARQ-ACK of the SPS PDSCH), then there is no PDCCH to schedule the PDSCH. If there is no PUSCH or the PUSCH does not have a corresponding PDCCH, then only check T1mux needs to be checked, and T2mux does not need to be checked. If the PUCCH carries CSI and / or SR, since there is no corresponding PDSCH, T1mux does not need to be checked. Furthermore, if there is no PUSCH or the PUSCH does not have a corresponding PDCCH, then T2mux does not need to be checked either.

[0163] If two PUCCHs overlap, and at least one PUCCH is repeatedly transmitted (i.e., repeatedly transmitting UCI in each time slot across multiple time slots), then only overlapping repetitions are processed according to transmission priority, discarding lower priority ones, without affecting non-overlapping repetitions. If a PUCCH overlaps with a repeatedly transmitted PUSCH, when the PUSCH uses time slot-based repetition (R15 repetition, or R16 repetition type A), the UCI carried by the PUCCH is transferred to one or more PUSCH time slots overlapping with the PUCCH for transmission; when the PUSCH uses R16 repetition type B, the UCI carried by the PUCCH is transferred to the earliest actual repetition PUSCH overlapping with the PUCCH, containing more than one symbol (an actual repetition is a repetition PUSCH obtained after segmentation based on unavailable symbols, DL symbols, time slot boundaries, etc.); the PUSCHs of one or more repetitions overlapping with the PUCCH mentioned above must satisfy the multiplexing timeline. If a multi-slot PUCCH overlaps with a single-slot or multi-slot PUSCH, the overlapping PUSCH is discarded to ensure that the repeated transmission of PUCCH is not interrupted.

[0164] When uplink channels with different physical layer priorities overlap in the time domain, and multiplexing transmission of uplink channels with different priorities is supported, there may be multiple PUSCHs with different priorities that overlap with a single PUCCH in the time domain. For example, when a PUCCH overlaps with multiple PUSCHs, the UCI on the PUCCH is transferred to the PUSCH that overlaps with it for transmission, and thus the PUCCH is not transmitted. In this case, there is no clear method for selecting a PUSCH from multiple PUSCHs to carry the UCI on the PUCCH.

[0165] To address the aforementioned technical problems, this invention provides a method for transmitting UCI on a PUSCH, which can be applied to terminals or network-side devices.

[0166] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems may include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0172] The application scenarios described in the embodiments of this invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of this invention, and do not constitute a limitation on the technical solutions provided by the embodiments of this invention. As those skilled in the art will know, with the emergence of new application scenarios, the technical solutions provided by the embodiments of this invention are also applicable to similar technical problems.

[0173] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0174] Example 1: This example provides a method for transmitting UCI on a PUSCH, which can be applied to terminals, such as... Figure 1 As shown, the specific implementation of this method is as follows:

[0175] Step 100: Determine that the PUCCH carrying UCI has temporal resource overlap with multiple PUSCHs of different physical layer priorities;

[0176] Step 101: Select one PUSCH from the plurality of PUSCHs according to a predetermined selection rule, or select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH;

[0177] Step 102: Transmit the UCI via the selected PUSCH.

[0178] This invention addresses the problem of selecting a PUCCH to transmit the UCI carried by a PUCCH when multiple PUSCHs overlap with PUCCHs in the time domain and the multiple PUSCHs contain PUSCHs with different physical priorities. It should be noted that the method provided in this embodiment is predicated on the existence of multiple PUSCHs overlapping with PUCCHs in the time domain and the presence of PUSCHs with different physical priorities. Currently, no method is provided under this condition for selecting one PUSCH to transmit the UCI carried by the PUCCH.

[0179] This embodiment provides two ways to select a PUSCH:

[0180] Rule 1: Select one PUSCH from multiple PUSCHs according to the predetermined selection rules;

[0181] In practice, the physical layer priority of multiple PUSCHs is not distinguished. Instead, a PUSCH is selected from multiple PUSCHs that overlap with the PUCCH temporal domain resources according to a predetermined selection rule.

[0182] Rule 2: Select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH.

[0183] As an optional implementation, the physical layer priority of the PUCCH includes high priority and low priority;

[0184] If the physical layer priority of the PUCCH is high, then rule 2 above is used to select the PUSCH to transmit the UCI carried by the PUCCH, that is, to select the PUSCH with the same physical layer priority as the PUCCH from the plurality of PUSCHs; or,

[0185] If the physical layer priority of the PUCCH is high, then rule 1 above is used to select the UCI carried by the PUCCH for transmission via PUSCH.

[0186] If the physical layer priority of the PUCCH is low, then rule 1 or rule 2 above is used to select the PUSCH to transmit the UCI carried by the PUCCH. In practice, a PUSCH is selected from the plurality of PUSCHs according to a predetermined selection rule, or a PUSCH with the same physical layer priority as the PUCCH is selected from the plurality of PUSCHs.

[0187] The high priority is a priority greater than the priority threshold determined according to the service type, or a high priority directly defined according to the service type. The low priority is a priority not greater than the priority threshold determined according to the service type, or a low priority directly defined according to the service type. Alternatively, the priority is determined according to configuration signaling, which can be higher-layer signaling or an indication field in the PDCCH that schedules PUCCH and PUSCH transmissions. The priority can have two levels, namely low priority and high priority, or more levels.

[0188] As an optional implementation, the PUCCH carrying UCI is one of a plurality of time-division multiplexed PUCCHs.

[0189] It should be noted that if there are multiple Time Division Multiplexing (TDM) PUCCHs, each PUCCH can select one PUSCH to transmit the UCI carried by that PUCCH according to rule 1 or rule 2 above.

[0190] As an optional implementation, this embodiment also provides the following undesirable scenarios:

[0191] Scenario 1: It is not desirable for multiple PUCCHs with different priorities to choose the same PUSCH for UCI transmission.

[0192] In this embodiment, the "not expected" is used to characterize situations that should be avoided during base station scheduling or configuration. If such situations occur, they can be considered as incorrect scheduling or configuration, and no specific rules are set for UE behavior.

[0193] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUCCHs with different priorities selected for UCI transmission on the same PUSCH.

[0194] Scenario 2: It is not expected that multiple PUCCHs carrying HARQ-ACKs with different priorities will choose to transmit HARQ-ACKs on the same PUSCH.

[0195] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUSCHs carrying HARQ-ACKs with different priorities that are selected to perform HARQ-ACK transmission on the same PUSCH.

[0196] Case 3: Only a maximum of two HARQ-ACK sequences with different priorities are supported for transmission on one PUSCH, wherein the different priority HARQ-ACK sequences include a high priority HARQ-ACK sequence and a low priority HARQ-ACK sequence.

[0197] In practice, before selecting a PUSCH from multiple PUSCHs, it is determined that there are at most two HARQ-ACK sequences with different priorities being transmitted on the same PUSCH.

[0198] Scenario 4: It is not expected that multiple PUCCHs with the same priority will choose to perform UCI transmission on the same PUSCH.

[0199] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUCCHs with the same priority that are selected for UCI transmission on the same PUSCH.

[0200] Case 5: It is not expected that multiple PUCCHs carrying HARQ-ACKs with the same priority will choose to transmit HARQ-ACKs on the same PUSCH.

[0201] In practice, it was determined that there were no multiple PUCCHs carrying HARQ-ACKs with the same priority that would choose to transmit HARQ-ACKs on the same PUSCH.

[0202] As an optional implementation, for rule 2, selecting the PUSCH with the same physical layer priority as the PUCCH from the plurality of PUSCHs includes one of the following selection methods:

[0203] Method 1: If there are multiple PUSCHs with the same priority as the PUCCH, then select one PUSCH from the multiple PUSCHs with the same priority as the PUCCH according to a predetermined selection rule.

[0204] Method 2: If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then a PUSCH with a different priority than the PUCCH is selected according to a predetermined selection rule; or,

[0205] If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then it is determined whether the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH according to the agreed rules or configuration signaling.

[0206] In implementation, if no PUSCH has the same priority as the PUCCH, and the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH according to the agreed rules or configuration signaling, then a predetermined selection rule is used to select a PUSCH from the PUSCHs with a different priority than the PUCCH; and / or,

[0207] If there is no PUSCH with the same priority as the PUCCH, and it is determined according to the agreed rules or configuration signaling that the UCI of the PUCCH is not allowed to be transmitted on a PUSCH with a different priority than the PUCCH, then the PUCCH or the multiple PUSCHs are discarded.

[0208] Method 3: Select from the plurality of PUSCHs a PUSCH that has the same physical layer priority as the PUCCH and does not overlap in the time domain with PUSCHs of different priorities on the carrier on which the PUSCH is transmitted.

[0209] In practice, for example, when a low-priority PUCCH overlaps with multiple PUSCHs, the low-priority PUSCH that does not overlap with a high-priority PUSCH on the carrier on which it is transmitted (i.e., it will not be canceled by a high-priority PUSCH) is selected first to transmit the UCI on the low-priority PUCCH.

[0210] As an optional implementation, the predetermined selection rules include any one or more of the following:

[0211] Rule 1: If there is a PUSCH carrying A-CSI among the multiple PUSCHs, then the PUSCH carrying A-CSI shall be selected.

[0212] Rule 2: If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and there is a first type of PUSCH, then the first type of PUSCH is selected. The first type of PUSCH is a PUSCH with PDCCH scheduling.

[0213] Rule 3: If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and only the second type of PUSCH exists, then the second type of PUSCH is selected. The second type of PUSCH is a PUSCH that does not have PDCCH scheduling.

[0214] Rule 4: If multiple Type I PUSCHs are transmitted on multiple carriers when selecting Type I PUSCHs, or multiple Type II PUSCHs are transmitted on multiple carriers when selecting Type II PUSCHs, then select a PUSCH on a carrier according to the carrier number.

[0215] Optionally, select the PUSCH on the carrier with the smallest carrier number.

[0216] Rule 5: If multiple PUSCHs are transmitted on multiple carriers and have different SCSs, then the PUSCH in the earliest time slot among the multiple carriers is selected.

[0217] Rule 6: If, when selecting a PUSCH on a carrier based on the carrier number, there are multiple non-overlapping PUSCHs in the time domain on the selected carrier, then the PUSCH with the earliest start symbol among the multiple PUSCHs shall be selected.

[0218] In practice, the predetermined selection rules specifically include: for PUSCHs that overlap with PUCCH in the time domain, if there is a PUSCH carrying A-CSI, then this PUSCH is selected first; otherwise (i.e., there is no PUSCH carrying A-CSI), if there are both PUSCHs with DCI scheduling and PUSCHs without corresponding DCI (e.g., CG PUSCH, SP-CSI PUSCH, etc.), then the PUSCH with DCI scheduling is selected first; if there is only one type of PUSCH (PUSCH with DCI scheduling, or PUSCH without corresponding DCI) and multiple PUSCHs overlap with PUCCHs on multiple carriers, then the PUSCH on the carrier with the smallest carrier number is selected first; if multiple TDM PUSCHs overlap with PUCCHs on a selected carrier, then the PUSCH with the earliest start symbol is selected first.

[0219] If PUSCHs on multiple carriers have different SCSs, then after determining that there is no PUSCH carrying A-CSI, for the PUSCH existing in the earliest time slot among the time slots where the PUSCHs on multiple carriers are located, if the PUSCH existing in the earliest time slot contains multiple PUSCHs with different physical priorities, then the selection is made according to the rules in this embodiment.

[0220] Based on such Figure 2 The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0221] 1) Select PUSCH using rule 1:

[0222] In practice, among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH3 carrying A-CSI is selected to transmit UCI on the PUCCH, thus no longer transmitting PUCCH.

[0223] 2) Select PUSCH using rule 2:

[0224] In practice, among PUSCH1 to PUSCH3 that overlap with PUCCH time-domain resources, PUSCHs with the same priority as PUCCH, namely PUSCH2 and PUSCH3, are determined. From PUSCH2 and PUSCH3, PUSCH3 carrying A-CSI is selected to transmit UCI on PUCCH, so that PUCCH is no longer transmitted.

[0225] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0226] Based on such Figure 3 The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0227] 1) Select PUSCH using rule 1:

[0228] Among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH1 of the LP carrying A-CSI is selected to transmit UCI on the PUCCH, so that PUCCH is no longer transmitted.

[0229] 2) Select PUSCH using rule 2:

[0230] From PUSCH1 to PUSCH3 that overlap with PUCCH time domain resources, determine the PUSCH with the same priority as PUCCH, namely PUSCH2 and 3. If it is determined that there is no PUSCH carrying A-CSI in PUSCH2 and 3, and the PUSCH on CC2 and CC3 are of the same type (e.g., both are PUSCH with corresponding DCI, or both are PUSCH without corresponding DCI), then select HP PUSCH2 on CC2 to transmit UCI according to CC number.

[0231] If it is determined that there is no PUSCH carrying A-CSI in PUSCH2 and 3, and the PUSCH types on CC2 and CC3 are different, for example, the PUSCH on CC3 is a PUSCH with a corresponding DCI, while the PUSCH on CC2 is a PUSCH without a corresponding DCI, then HP PUSCH3 on CC3 is selected to transmit UCI.

[0232] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0233] Based on such Figure 4 , Figure 5 The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0234] 1) Select PUSCH using rule 1:

[0235] like Figure 4 As shown, among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH1 of the LP carrying A-CSI is selected to transmit UCI on the PUCCH, so that the PUCCH is no longer transmitted.

[0236] 2) Select PUSCH using rule 2:

[0237] If, among PUSCH1 to PUSCH3 which overlap with PUCCH time-domain resources, it is determined that there is no PUSCH with the same priority as PUCCH, and according to agreed rules or configuration signaling, it is determined that UCI on PUCCH is supported for transmission to a PUSCH with a different priority than PUCCH, then PUSCH1 carrying the LP of A-CSI is selected from PUSCH1 to PUSCH3 to transmit UCI on PUCCH, thus no longer transmitting PUCCH. Figure 4 As shown;

[0238] If it is determined that there is no PUSCH with the same priority as the PUCCH, and according to the agreed rules or configuration signaling it is determined that UCI transfer on the PUCCH is not supported to a PUSCH with a different priority than the PUCCH, then only the HPPUCCH carrying the AN is transmitted, and all PUSCHs of LPs that overlap with the PUCCH are discarded. Figure 5 As shown.

[0239] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0240] based on Figure 6 The diagram illustrates the overlap between PUCCH and PUSCH, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. This means that one PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers than the PUCCH. The selection of the PUSCH carrying UCI according to this embodiment is as follows:

[0241] 1) Select PUSCH using rule 1:

[0242] Regardless of priority, the HP PUSCH with A-CSI on CC1 is selected to carry the LP UCI;

[0243] 2) Select PUSCH using rule 2:

[0244] In one case (Rule 2-1), only priority is distinguished, and the selection is made in the LP PUSCH according to the predetermined selection rules in the prior art. In this case, the LP PUSCH on CC2 is selected to transmit the LP UCI according to the CC number.

[0245] In another case (Rule 2-2), when prioritizing, the LP PUSCH that will not be canceled by the HP PUSCH is selected from the LP PUSCH, that is, the PUSCH that does not overlap with the HP PUSCH on the same carrier. In this case, the LP PUSCH on CC3 is selected to transmit the LP UCI.

[0246] Example 2: Based on the same inventive concept, this embodiment of the invention also provides a method for transmitting UCI on a PUSCH, which can be applied to network-side devices, such as... Figure 7 As shown, the specific implementation of this method is as follows:

[0247] Step 700: Determine that the PUCCH carrying UCI has temporal resource overlap with multiple PUSCHs of different physical layer priorities;

[0248] Step 701: Select one PUSCH from the plurality of PUSCHs according to a predetermined selection rule, or select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH;

[0249] Step 702: Receive the UCI through the selected PUSCH.

[0250] This invention addresses the problem of selecting a PUCCH to transmit the UCI carried by a PUCCH when multiple PUSCHs overlap with PUCCHs in the time domain and the multiple PUSCHs contain PUSCHs with different physical priorities. It should be noted that the method provided in this embodiment is predicated on the existence of multiple PUSCHs overlapping with PUCCHs in the time domain and the presence of PUSCHs with different physical priorities. Currently, no method is provided under this condition for selecting one PUSCH from multiple PUSCHs with different physical priorities to receive the UCI carried by the PUCCH.

[0251] This embodiment provides two ways to select a PUSCH:

[0252] Rule 1: Select one PUSCH from multiple PUSCHs according to the predetermined selection rules;

[0253] In practice, the physical priority of multiple PUSCHs is not distinguished; instead, a PUSCH is selected from multiple PUSCHs that overlap with the PUCCH temporal resources according to a predetermined selection rule.

[0254] Rule 2: Select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH.

[0255] As an optional implementation, the physical layer priority of the PUCCH includes high priority and low priority;

[0256] If the physical layer priority of the PUCCH is high, then rule 2 above is used to select the PUSCH to transmit the UCI carried by the PUCCH, that is, to select the PUSCH with the same physical layer priority as the PUCCH from the plurality of PUSCHs; or,

[0257] If the physical layer priority of the PUCCH is high, then rule 1 above is used to select the UCI carried by the PUCCH for transmission via PUSCH.

[0258] If the physical layer priority of the PUCCH is low, then rule 1 or rule 2 above is used to select the PUSCH to transmit the UCI carried by the PUCCH. In practice, a PUSCH is selected from the plurality of PUSCHs according to a predetermined selection rule, or a PUSCH with the same physical layer priority as the PUCCH is selected from the plurality of PUSCHs.

[0259] Wherein, the high priority is a priority greater than the priority threshold determined according to the service type, and the low priority is a priority not greater than the priority threshold determined according to the service type. Alternatively, the priority is determined according to configuration signaling, which can be higher-layer signaling or an indication field in the PDCCH that schedules PUCCH and PUSCH transmissions. The priority can have two levels, namely low priority and high priority, or more levels.

[0260] As an optional implementation, the PUCCH carrying UCI is one of a plurality of time-division multiplexed PUCCHs.

[0261] It should be noted that if there are multiple time-division multiplexing (TDM) PUCCHs, each PUCCH can select one PUSCH to transmit the UCI carried by that PUCCH according to rule 1 or rule 2 above.

[0262] As an optional implementation, this embodiment also provides the following undesirable scenarios:

[0263] Scenario 1: It is not desirable for multiple PUCCHs with different priorities to choose the same PUSCH for UCI transmission.

[0264] In this embodiment, the "not expected" is used to characterize situations that should be avoided during base station scheduling or configuration. If such situations occur, they can be identified as incorrect scheduling or incorrect configuration, and no specific rules are made for UE behavior.

[0265] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUCCHs with different priorities selected for UCI transmission on the same PUSCH.

[0266] Scenario 2: It is not expected that multiple PUCCHs carrying HARQ-ACKs with different priorities will choose to transmit HARQ-ACKs on the same PUSCH.

[0267] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUSCHs carrying HARQ-ACKs with different priorities that are selected to perform HARQ-ACK transmission on the same PUSCH.

[0268] Case 3: Only a maximum of two HARQ-ACK sequences with different priorities are supported for transmission on one PUSCH, wherein the different priority HARQ-ACK sequences include a high priority HARQ-ACK sequence and a low priority HARQ-ACK sequence.

[0269] In practice, before selecting a PUSCH from multiple PUSCHs, it is determined that there are at most two HARQ-ACK sequences with different priorities being transmitted on the same PUSCH.

[0270] Scenario 4: It is not expected that multiple PUCCHs with the same priority will choose to perform UCI transmission on the same PUSCH.

[0271] In practice, before selecting a PUSCH from multiple PUSCHs, it is ensured that there are no multiple PUCCHs with the same priority that are selected for UCI transmission on the same PUSCH.

[0272] Case 5: It is not expected that multiple PUCCHs carrying HARQ-ACKs with the same priority will choose to transmit HARQ-ACKs on the same PUSCH.

[0273] In practice, it was determined that there were no multiple PUCCHs carrying HARQ-ACKs with the same priority that would choose to transmit HARQ-ACKs on the same PUSCH.

[0274] As an optional implementation, for rule 2, selecting the PUSCH with the same physical layer priority as the PUCCH from the plurality of PUSCHs includes one of the following selection methods:

[0275] Method 1: If there are multiple PUSCHs with the same priority as the PUCCH, then select one PUSCH from the multiple PUSCHs with the same priority as the PUCCH according to a predetermined selection rule.

[0276] Method 2: If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then a PUSCH with a different priority than the PUCCH is selected according to a predetermined selection rule; or,

[0277] If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then it is determined whether the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH according to the agreed rules or configuration signaling.

[0278] In implementation, if no PUSCH has the same priority as the PUCCH, and the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH according to the agreed rules or configuration signaling, then a predetermined selection rule is used to select a PUSCH from the PUSCHs with a different priority than the PUCCH; and / or,

[0279] If there is no PUSCH with the same priority as the PUCCH, and it is determined according to the agreed rules or configuration signaling that the UCI of the PUCCH is not allowed to be transmitted on a PUSCH with a different priority than the PUCCH, then the PUCCH or the multiple PUSCHs are discarded.

[0280] Method 3: Select from the plurality of PUSCHs a PUSCH that has the same physical layer priority as the PUCCH and does not overlap in the time domain with PUSCHs of different priorities on the carrier on which the PUSCH is transmitted.

[0281] In practice, for example, when a low-priority PUCCH overlaps with multiple PUSCHs, the low-priority PUSCH that does not overlap with a high-priority PUSCH on the carrier on which it is transmitted (i.e., it will not be canceled by a high-priority PUSCH) is selected first to transmit the UCI on the low-priority PUCCH.

[0282] As an optional implementation, the predetermined selection rules include any one or more of the following:

[0283] Rule 1: If there is a PUSCH carrying A-CSI among the multiple PUSCHs, then the PUSCH carrying A-CSI shall be selected.

[0284] Rule 2: If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and there is a first type of PUSCH, then the first type of PUSCH is selected. The first type of PUSCH is a PUSCH with PDCCH scheduling.

[0285] Rule 3: If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and only the second type of PUSCH exists, then the second type of PUSCH is selected. The second type of PUSCH is a PUSCH that does not have PDCCH scheduling.

[0286] Rule 4: If multiple Type I PUSCHs are transmitted on multiple carriers when selecting Type I PUSCHs, or multiple Type II PUSCHs are transmitted on multiple carriers when selecting Type II PUSCHs, then select a PUSCH on a carrier according to the carrier number.

[0287] Optionally, select the PUSCH on the carrier with the smallest carrier number.

[0288] Rule 5: If multiple PUSCHs are transmitted on multiple carriers and have different SCSs, then the PUSCH in the earliest time slot among the multiple carriers is selected.

[0289] Rule 6: If, when selecting a PUSCH on a carrier based on the carrier number, there are multiple non-overlapping PUSCHs in the time domain on the selected carrier, then the PUSCH with the earliest start symbol among the multiple PUSCHs shall be selected.

[0290] In practice, the predetermined selection rules specifically include: for PUSCHs that overlap with PUCCH in the time domain, if there is a PUSCH carrying A-CSI, then this PUSCH is selected first; otherwise (i.e., there is no PUSCH carrying A-CSI), if there are both PUSCHs with DCI scheduling and PUSCHs without corresponding DCI (e.g., CG PUSCH, SP-CSI PUSCH, etc.), then the PUSCH with DCI scheduling is selected first; if there is only one type of PUSCH (PUSCH with DCI scheduling, or PUSCH without corresponding DCI) and multiple PUSCHs overlap with PUCCHs on multiple carriers, then the PUSCH on the carrier with the smallest carrier number is selected first; if multiple TDM PUSCHs overlap with PUCCHs on a selected carrier, then the PUSCH with the earliest start symbol is selected first.

[0291] If PUSCHs on multiple carriers have different SCSs, then after determining that there is no PUSCH carrying A-CSI, for the PUSCH existing in the earliest time slot among the time slots where the PUSCHs on multiple carriers are located, if the PUSCH existing in the earliest time slot contains multiple PUSCHs with different physical priorities, then the selection is made according to the rules in this embodiment.

[0292] Based on such Figure 8 The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0293] 1) Select PUSCH using rule 1:

[0294] In practice, among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH3 carrying A-CSI is selected to transmit UCI on the PUCCH, thus no longer transmitting PUCCH.

[0295] 2) Select PUSCH using rule 2:

[0296] In practice, among PUSCH1 to PUSCH3 that overlap with PUCCH time-domain resources, PUSCHs with the same priority as PUCCH, namely PUSCH2 and PUSCH3, are determined. From PUSCH2 and PUSCH3, PUSCH3 carrying A-CSI is selected to transmit UCI on PUCCH, so that PUCCH is no longer transmitted.

[0297] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0298] Based on such Figure 9The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0299] 1) Select PUSCH using rule 1:

[0300] Among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH1 of the LP carrying A-CSI is selected to transmit UCI on the PUCCH, so that PUCCH is no longer transmitted.

[0301] 2) Select PUSCH using rule 2:

[0302] From PUSCH1 to PUSCH3 that overlap with PUCCH time domain resources, determine the PUSCH with the same priority as PUCCH, namely PUSCH2 and 3. If it is determined that there is no PUSCH carrying A-CSI in PUSCH2 and 3, and the PUSCH on CC2 and CC3 are of the same type (e.g., both are PUSCH with corresponding DCI, or both are PUSCH without corresponding DCI), then select HP PUSCH2 on CC2 to transmit UCI according to CC number.

[0303] If it is determined that there is no PUSCH carrying A-CSI in PUSCH2 and 3, and the PUSCH types on CC2 and CC3 are different, for example, the PUSCH on CC3 is a PUSCH with a corresponding DCI, while the PUSCH on CC2 is a PUSCH without a corresponding DCI, then HP PUSCH3 on CC3 is selected to transmit UCI.

[0304] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0305] Based on such Figure 10 , Figure 11The present invention provides an implementation method for selecting the PUSCH carrying UCI, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. Different PUSCHs are on different carriers. One PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers from the PUCCH. The specific selection method is as follows:

[0306] 1) Select PUSCH using rule 1:

[0307] like Figure 10 As shown, among multiple PUSCHs that overlap with PUCCH time-domain resources, PUSCH1 of the LP carrying A-CSI is selected to transmit UCI on the PUCCH, so that the PUCCH is no longer transmitted.

[0308] 2) Select PUSCH using rule 2:

[0309] If, among PUSCH1 to PUSCH3 which overlap with PUCCH time-domain resources, it is determined that there is no PUSCH with the same priority as PUCCH, and according to agreed rules or configuration signaling, it is determined that UCI on PUCCH is supported for transmission to a PUSCH with a different priority than PUCCH, then PUSCH1 carrying the LP of A-CSI is selected from PUSCH1 to PUSCH3 to transmit UCI on PUCCH, thus no longer transmitting PUCCH. Figure 10 As shown;

[0310] If it is determined that there is no PUSCH with the same priority as the PUCCH, and according to the agreed rules or configuration signaling it is determined that UCI transfer on the PUCCH is not supported to a PUSCH with a different priority than the PUCCH, then only the HPPUCCH carrying the AN is transmitted, and all PUSCHs of LPs that overlap with the PUCCH are discarded. Figure 11 As shown.

[0311] The above embodiments only take PUCCH as a high-priority channel as an example. The same applies to PUCCH as a low-priority channel, and will not be repeated. The above only takes PUCCH carrying AN as an example. The same applies to PUCCH carrying other UCIs, and will not be repeated. The above only takes the overlapping case in a time slot as an example. If the time unit definition for multiplexing transmission between uplink channels of different priorities is not a time slot, but a sub-time slot, then replacing the time slot with a sub-time slot is the same, and will not be repeated.

[0312] based on Figure 12The diagram illustrates the overlap between PUCCH and PUSCH, where LP represents low priority, HP represents high priority, and AN is an abbreviation for HARQ-ACK. This means that one PUSCH may be on the same carrier as the PUCCH, or all PUSCHs may be on different carriers than the PUCCH. The selection of the PUSCH carrying UCI according to this embodiment is as follows:

[0313] 1) Select PUSCH using rule 1:

[0314] Regardless of priority, the HP PUSCH with A-CSI on CC1 is selected to carry the LP UCI;

[0315] 2) Select PUSCH using rule 2:

[0316] In one case (Rule 2-1), only priority is distinguished, and the selection is made in the LP PUSCH according to the predetermined selection rules in the prior art. In this case, the LP PUSCH on CC2 is selected to transmit the LP UCI according to the CC number.

[0317] In another case (Rule 2-2), when prioritizing, the LP PUSCH that will not be canceled by the HP PUSCH is selected from the LP PUSCH, that is, the PUSCH that does not overlap with the HP PUSCH on the same carrier. In this case, the LP PUSCH on CC3 is selected to transmit the LP UCI.

[0318] Example 3: This example provides a system for UCI transmission on the PUSCH, which can be applied to a system including a terminal and network-side equipment. The implementation steps of the system are described below:

[0319] like Figure 13 As shown, the system includes a terminal 1300 and a network-side device 1301. After the terminal and the network-side device select a PUSCH to carry UCI according to the same rules, the terminal transmits the UCI carried by the PUCCH on the selected PUSCH, and the network-side device receives the UCI on the selected PUSCH. This ensures that the terminal and the network-side device select the same PUSCH for transmitting UCI, thus ensuring the normal transmission of UCI.

[0320] In this embodiment, the rules include a predetermined selection rule or the selection of a PUSCH with the same physical layer priority as the PUCCH from the plurality of PUSCHs. The specific implementation of selecting the PUSCH carrying UCI according to the rules can be referred to the implementation of the terminal side or network device side described above, and will not be repeated here.

[0321] Example 4: Based on the same inventive concept, this embodiment of the invention also provides a terminal. Since this terminal is the terminal corresponding to the method of this embodiment of the invention, and the principle of the terminal in solving the problem is similar to that of the method, the implementation of this terminal can refer to the implementation of the method, and the repeated parts will not be described again.

[0322] like Figure 14 As shown, this embodiment of the invention also provides a terminal, which includes a memory, a transceiver, and a processor:

[0323] Transceiver 1400 is used to receive and send data under the control of processor 1410.

[0324] Among them, Figure 14 In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 1410 and memory represented by memory 1420 together. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. The transceiver 1400 can be multiple components, including transmitters and receivers, providing a unit for communicating with various other devices over a transmission medium, including wireless channels, wired channels, optical fibers, etc. For different user equipment, the user interface 1430 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

[0325] Processor 1410 is responsible for managing the bus architecture and general processing, while memory 1420 can store data used by processor 1410 when performing operations.

[0326] Optionally, the processor 1410 can be a CPU (Central Processing Unit), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or CPLD (Complex Programmable Logic Device), and the processor can also adopt a multi-core architecture.

[0327] The processor executes any of the methods described in the embodiments of this application according to the obtained executable instructions by calling a computer program stored in memory. The processor and memory may also be physically separated.

[0328] Processor, configured to read the computer program in the memory and perform the following operations:

[0329] It is determined that the PUCCH carrying the UCI has temporal resource overlap with multiple PUSCHs of different physical layer priorities; a PUSCH is selected from the multiple PUSCHs according to a predetermined selection rule, or a PUSCH with the same physical layer priority as the PUCCH is selected from the multiple PUSCHs; the UCI is transmitted through the selected PUSCH.

[0330] As an optional implementation, the processor is specifically configured to execute:

[0331] If the PUCCH has a high priority, then select a PUSCH from the plurality of PUSCHs that has the same physical layer priority as the PUCCH;

[0332] If the PUCCH has a low priority, then a PUSCH is selected from the plurality of PUSCHs according to a predetermined selection rule, or a PUSCH with the same physical layer priority as the PUCCH is selected from the plurality of PUSCHs.

[0333] As an optional implementation, the PUCCH carrying UCI is one of a plurality of time-division multiplexed PUCCHs.

[0334] As an optional implementation, before selecting a PUSCH from the plurality of PUSCHs according to a predetermined selection rule, or selecting a PUSCH from the plurality of PUSCHs with the same physical layer priority as the PUCCH, the processor is further configured to perform:

[0335] It is determined that there are no multiple PUCCHs with different priorities selected for UCI transmission on the same PUSCH; or,

[0336] If it is determined that there are no multiple PUCCHs carrying HARQ-ACKs with different priorities, HARQ-ACK transmission will be performed on the same PUSCH; or,

[0337] It is determined that at most two HARQ-ACK sequences with different priorities are transmitted on the same PUSCH; or,

[0338] It is determined that there are no multiple PUCCHs with the same priority choosing to perform UCI transmission on the same PUSCH; or,

[0339] If it is determined that there are no multiple PUCCHs carrying HARQ-ACKs with the same priority, HARQ-ACK transmission will be performed on the same PUSCH.

[0340] As an optional implementation, the processor is specifically configured to perform one of the following:

[0341] Method 1: If there are multiple PUSCHs with the same priority as the PUCCH, then select one PUSCH from the multiple PUSCHs with the same priority as the PUCCH according to a predetermined selection rule.

[0342] Method 2: If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then a PUSCH with a different priority than the PUCCH is selected according to a predetermined selection rule; or,

[0343] If it is determined that there is no PUSCH with the same priority as the PUCCH among the plurality of PUSCHs, then it is determined whether the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH according to the agreed rules or configuration signaling.

[0344] Method 3: Select from the plurality of PUSCHs a PUSCH that has the same physical layer priority as the PUCCH and does not overlap in the time domain with PUSCHs of different priorities on the carrier on which the PUSCH is transmitted.

[0345] As an optional implementation, after determining whether to allow the UCI of the PUCCH to be transmitted on a PUSCH with a different priority than the PUCCH according to agreed rules or configuration signaling, the processor is further configured to execute:

[0346] If it is determined that the UCI of the PUCCH is allowed to be transmitted on a PUSCH with a different priority than the PUCCH, then a PUSCH with a different priority than the PUCCH is selected according to a predetermined selection rule; and / or,

[0347] If it is determined that the UCI of a PUCCH is not allowed to be transmitted on a PUSCH with a different priority than the PUCCH, then the PUCCH or the plurality of PUSCHs are discarded.

[0348] As an optional implementation, the processor is further configured to execute:

[0349] If among the plurality of PUSCHs there are multiple PUSCHs with the same physical layer priority as the PUCCH and which do not overlap in the time domain with PUSCHs of different priorities on the carrier on which the PUSCH is transmitted, then among the multiple PUSCHs with the same physical layer priority as the PUCCH and which do not overlap in the time domain with PUSCHs of different priorities on the carrier on which the PUSCH is transmitted, one PUSCH is selected by reusing either method 1 or method 2.

[0350] As an optional implementation, the predetermined selection rule includes any one or more of the following:

[0351] If there is a PUSCH carrying A-CSI among the plurality of PUSCHs, then the PUSCH carrying A-CSI is selected;

[0352] If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and there is a first type of PUSCH, then the first type of PUSCH is selected. The first type of PUSCH is a PUSCH with PDCCH scheduling.

[0353] If there is no PUSCH carrying A-CSI among the multiple PUSCHs, and only the second type of PUSCH exists, then the second type of PUSCH is selected. The second type of PUSCH is a PUSCH that does not have PDCCH scheduling.

[0354] If multiple Type I PUSCHs are transmitted on multiple carriers when selecting Type I PUSCH, or multiple Type II PUSCHs are transmitted on multiple carriers when selecting Type II PUSCH, then select a PUSCH on a carrier according to the carrier number.

[0355] If multiple PUSCHs are transmitted on multiple carriers and have different SCSs, then the PUSCH in the earliest time slot among the multiple carriers is selected.

[0356] If a PUSCH on a carrier is selected based on the carrier number, and there are multiple non-overlapping PUSCHs in the time domain on the selected carrier, then the PUSCH with the earliest start symbol among the multiple PUSCHs is selected.

[0357] It should be noted that the terminal provided in this embodiment of the invention can implement all the method steps implemented in the above method embodiment and achieve the same technical effect. Therefore, the parts and beneficial effects that are the same as those in the method embodiment will not be described in detail here.

[0358] Example 5: Based on the same inventive concept, this embodiment of the invention also provides a network-side device. Since this device is the device corresponding to the method of this embodiment of the invention, and the principle of the device in solving the problem is similar to that of the method, the implementation of this device can refer to the implementation of the method, and the repeated parts will not be described again.
