[0116] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0117] In some embodiments, UCI can be categorized as follows:

[0118] The first type is the Channel Quality Indicator (CQI).

[0119] CQI can be used to feed back channel-related information measured by the terminal based on the downlink reference signal to network devices such as base stations. Based on the CQI, the base station can better perform scheduling according to the channel conditions of the terminal, thereby improving system communication efficiency and user experience.

[0120] The second type is Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK).

[0121] HARQ-ACK can be used to report the reception status of downlink data / information to the base station. The HARQ-ACK message includes an acknowledgment (ACK) message and / or a negative-acknowledgment (NACK) message. An ACK message indicates that the terminal successfully detected and received the corresponding downlink channel, while a NACK message indicates that the terminal did not detect and receive the corresponding downlink channel within the time slot indicated by the base station. Based on the HARQ-ACK information, the base station determines whether to retransmit the downlink channel, thereby greatly improving the reliability of the downlink communication link.

[0122] The third type is the scheduling request (SR).

[0123] Scheduler (SR) can be used to send scheduling requests to the base station. SRs are divided into positive SRs and negative SRs, corresponding to when a terminal requests a scheduling opportunity and when it does not, respectively. Based on this, network devices can better understand the terminal's scheduling requests, thereby optimizing system transmission efficiency and reducing terminal transmission latency.

[0124] In some embodiments, UCI differentiates based on the type of information carried, exhibiting different time-domain transmission behaviors, including periodic transmission, aperiodic transmission, and semi-persistent transmission. These different time-domain transmission behaviors achieve a good trade-off in terms of resource overhead and transmission latency.

[0125] In some embodiments, UCI can be carried through different uplink channels or uplink signals. Specifically, periodic CQI can be carried through the Physical Uplink Control Channel (PUCCH), aperiodic CQI can be carried through the Physical Uplink Shared Channel (PUSCH), HARQ-ACK can be carried through PUCCH or PUSCH, and SR can be carried through PUCCH or Sounding Reference Signal (SRS).

[0126] Given the importance of UCI and its significant contribution to the performance of the entire wireless communication system, the reliability, timeliness, accuracy, and flexibility of UCI transmission should be guaranteed.

[0127] In some embodiments, UCI can be transmitted on PUCCH.

[0128] Given the importance and diversity of UCI, UCI transmission requires high reliability and flexibility. To support UCI transmission, this disclosure provides several PUCCH formats, as shown in Table 1, for carrying different UCIs and adapting to the diverse service needs of communication systems.

[0129] Table 1

[0130] As can be seen from Table 1, different PUCCH formats have different channel structures, transmission methods, and processing procedures.

[0131] From a flexibility perspective, network devices such as base stations can configure up to four PUCCH resource sets for a terminal within a Bandwidth Part (BWP). Each PUCCH resource set contains up to 32 PUCCH resources.

[0132] In some embodiments, a complex indication mechanism is required to accurately indicate the PUCCH resource used by the terminal for UCI transmission. Furthermore, the PUCCH resource indication method differs within different PUCCH resource sets. For example, PUCCH resource set #0 can contain up to 32 PUCCH resources. To indicate all PUCCH resources using a limited number of PUCCH Resource Indicator (PRI) bits (e.g., 3 bits), the PUCCH resource used for PUCCH transmission needs to be determined by combining the Control Channel Element (CCE) index. For other PUCCH resource sets, the resources used for PUCCH transmission can be directly indicated by the PRI carried in the DCI.

[0133] In some embodiments, UCI can also be carried via PUSCH. There are two cases for carrying UCI via PUSCH:

[0134] In one scenario, the terminal can be instructed to carry UCI on the PUSCH via Downlink Control Information (DCI).

[0135] In another scenario, based on the UCI type and timing relationship, the UCI that should have been transmitted on the PUCCH can be piggybacked to the PUSCH for transmission.

[0136] In the first scenario, the operation is relatively simple, but the cost is that the PUSCH needs to be scheduled additionally via DCI. If the base station instructs that the PUSCH does not carry an Uplink Scheduling Channel (UL-SCH), it will result in significant resource overhead.

[0137] In the second scenario, since the terminal has already begun preparing to transmit the PUCCH, the timing relationship between PUCCH and PUSCH transmissions needs to be considered. Additionally, considering the different priorities of different UCIs, the type of UCI also needs to be considered to ultimately determine the different timing relationships. Overall, the earliest Orthogonal Frequency Division Multiplexing (OFDM) symbol in the PUCCH and PUSCH that requires piggyback operation in terms of time cannot be earlier than a specific time point.

[0138] For example, the timing relationship can be as shown in Figure 1B, where the earliest OFDM symbol of the overlapping PUCCH and PUSCH corresponds to the time point T1, and T1 cannot be earlier than T2. ​​T2 is separated from the last OFDM symbol T0 of the relevant Physical Downlink Shared Channel (PDSCH) by a specific number of OFDM symbols (T_proc,2).

[0139] It is important to note that the timing relationships for different PDSCH types and different UCI types are not the same. In some embodiments, independent timing relationships can be defined, and rules for mapping various UCI types onto the PUSCH can be specified.

[0140] In some embodiments, to support UCI transmission, various PUCCH formats can be designed, and extremely complex multiplexing rules can be defined. This design complexity significantly increases the implementation costs on both the terminal and network device sides, and generates numerous extreme corner cases.

[0141] Taking PUCCH format #0 and PUCCH format #4 as examples, PUCCH format #0 is a sequence-based PUCCH format, as shown in Figure 1C, while PUCCH format #4 supports time-domain spread spectrum and frequency-domain spread spectrum, as shown in Figure 1D. Their processing procedures, resource allocation, and algorithm implementations are completely different. While this completely different channel structure design can, to some extent, address and adapt to the different needs of UCI transmission, it objectively increases the complexity of protocol design, terminal implementation, and network configuration.

[0142] In terms of resource allocation, different PUCCH resource indication methods were designed to meet the transmission requirements of different UCIs, which also increased the complexity of terminal implementation.

[0143] To enable UCI transmission on the PUSCH, an extremely complex timeline judgment and determination mechanism was designed. The terminal and base station need to determine the timing relationship based on the UCI type, PDSCH transmission time, PUCCH transmission time, and PUSCH transmission time, and determine whether the UCI can be transmitted on the PUSCH, greatly increasing the implementation complexity on both the terminal and network sides.

[0144] To achieve the multiplexing of different UCI types on the PUSCH, an extremely complex multiplexing and mapping mechanism was designed. Network devices and terminals need to determine the final UCI type and method transmitted on the PUSCH based on the priority of different UCI types and the actual UCI type being transmitted.

[0145] To determine the time-domain resources for PUCCH transmission, network devices need to pre-configure the time-domain resources for each PUCCH resource. Based on this, the specific transmission time-domain location needs to be determined through Radio Resource Control (RRC) signaling or timing indication information carried in the DCI.

[0146] To adapt to diverse scenarios and requirements in communication systems, the time and frequency resources for each PUCCH format can be flexibly configured. This increases the complexity of PUCCH applications to some extent. Terminals must support all PUCCH formats and all possible time and frequency resource configurations for each PUCCH format, further increasing the complexity of terminal implementation.

[0147] It can be seen that transmitting UCI via PUCCH increases the complexity of terminal implementation and increases the latency of UCI transmission.

[0148] In some embodiments, to reduce the complexity of carrying UCI via the PUCCH channel, UCI can be carried via the PUSCH.

[0149] The PUSCH design does not employ redundancy in its physical structure from a transmission reliability perspective. Instead, it relies on link adaptive methods to adjust the transmission scheme to achieve the reliability requirements of the data channel. It's important to note that the reliability requirements for data transmission and control information transmission differ in wireless communication systems. Typically, the initial transmission of data transmission requires a 10% Block Error Rate (BLER), while control information transmission typically requires a 1% BLER.

[0150] Although the physical structure of a PUSCH does not consider redundancy for reliability, transmission reliability can still be improved by adjusting the transmission method, allocating more physical resources, and reducing the effective code rate. However, in poor channel conditions, this will inevitably lead to a decrease in transmission efficiency. For example, using an extremely low code rate and enabling repeated transmissions will inevitably reduce information transmission efficiency, thus affecting the overall performance of the system.

[0151] To ensure that terminals and network devices have a consistent understanding of the UCI transmission method and to improve the reliability of UCI transmission, this disclosure provides the following information transmission method, terminal, network device, system, and storage medium.

[0152] Figure 2 is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to an information transmission method, which includes:

[0153] In step S2101, network device 102 sends uplink channel configuration information to terminal 101.

[0154] In some embodiments, terminal 101 receives uplink channel configuration information.

[0155] In some embodiments, the uplink channel includes, but is not limited to, PUCCH and / or PUSCH.

[0156] In some embodiments, the uplink channel configuration information can be used to configure PUCCH and / or dedicated PUSCH.

[0157] In one example, a dedicated PUSCH is a PUSCH designated for transmitting UCI, meaning that the PUSCH can be used to carry UCI but not for carrying (uplink) data.

[0158] In one example, the uplink channel configuration information can be used to configure the resources used by the uplink channel, including but not limited to time domain resources, frequency domain resources, code rate, and transmission port.

[0159] In one example, the uplink channel configuration information can be used to configure other relevant information about the uplink channel, including but not limited to at least one of the following: the reference signal associated with the uplink channel, whether uplink channel frequency hopping transmission is performed, and the number of repeated transmissions of the uplink channel.

[0160] In some embodiments, network device 102 may indicate the configuration of the uplink channel via dynamic signaling.

[0161] In some embodiments, network device 102 can configure the uplink channel via semi-static signaling.

[0162] In one example, network device 102 can configure a candidate resource set and / or candidate resources for the uplink channel, such as configuring a candidate PUSCH resource set and / or configuring candidate PUSCH resources within the candidate PUSCH resource set. Subsequently, one of the candidate PUSCH resource sets or a specific PUSCH resource can be activated or indicated via signaling. Alternatively, terminal 101 can determine one of the candidate PUSCH resource sets or a specific PUSCH resource based on a predefined method.

[0163] The above is merely an illustrative example, and this disclosure does not limit the method of configuring the uplink channel for network device 102.

[0164] In some embodiments, network device 102 may send uplink channel configuration information to terminal 101 after terminal 101 accesses the network.

[0165] In some embodiments, network device 102 may send uplink channel configuration information to terminal 101 based on a request from terminal 101.

[0166] In some embodiments, network device 102 may send uplink channel configuration information to terminal 101 based on its own implementation and / or its own policies.

[0167] In some embodiments, network device 102 may send uplink channel configuration information to terminal 101 when it is necessary to indicate the transmission mode of UCI.

[0168] The above is merely an illustrative example, and this disclosure does not limit the timing or conditions for the network device 102 to send uplink channel configuration information to the terminal 101.

[0169] In some embodiments, the uplink channel configuration information can be used to configure the PUCCH.

[0170] In some embodiments, the uplink channel configuration information can be used to configure a dedicated PUSCH. This dedicated PUSCH is a PUSCH specifically designated for transmitting UCI. That is, this PUSCH is designated to carry UCI and not (uplink) data.

[0171] In step S2102, network device 102 sends the first signaling to terminal 101.

[0172] In some embodiments, terminal 101 receives a first signaling.

[0173] In some embodiments, the first signaling may be used to configure or indicate the transmission mode of UCI.

[0174] In one example, the UCI may include, but is not limited to, at least one of the following: CQI; HARQ-ACK; SR.

[0175] In some embodiments, the transmission method of UCI includes, but is not limited to, at least one of the following: a first transmission method; a second transmission method.

[0176] In one example, the first transmission method is to transmit the UCI via PUCCH.

[0177] For example, in the first transmission mode, the terminal 101 can also pegback the UCI that should be transmitted on the PUCCH to the PUSCH for transmission. In this case, the PUSCH carries both the UCI and (uplink) data.

[0178] In one example, the second transmission method is to transmit UCI via a dedicated PUSCH.

[0179] For example, in the second transmission method, the dedicated PUSCH is a PUSCH specifically designated for transmitting UCI. That is, the dedicated PUSCH is designated to carry UCI and no longer carries (uplink) data.

[0180] In some embodiments, the first signaling may include, but is not limited to, at least one of the following: Radio Resource Control (RRC) signaling; Media Access Control-Control Element (MAC CE); Downlink Control Information (DCI).

[0181] In some embodiments, the first signaling may be multicast signaling or broadcast signaling, such as, but not limited to, system messages, such as System Information Block n (SIBn), where n may be a positive integer, such as 1, 2, 3, etc.

[0182] In some embodiments, network device 102 sends a first signaling message to terminal 101, taking into account the reliability of UCI transmission. The first signaling message configures or indicates the transmission mode of UCI, which may include a first transmission mode. Terminal 101 transmits UCI through PUCCH based on the first signaling message, thereby effectively improving the transmission reliability of UCI.

[0183] In some embodiments, considering the implementation complexity of terminal 101, network device 102 sends a first signaling to terminal 101. The first signaling configures or indicates the transmission mode of UCI, which may include a second transmission mode. Terminal 101 transmits UCI through PUSCH based on the first signaling, thereby reducing the implementation complexity of terminal and improving UCI transmission efficiency.

[0184] In some embodiments, network device 102 may send a first signaling to terminal 101 when considering service adaptation requirements. The first signaling may configure or indicate the transmission method of UCI, including a first transmission method and a second transmission method. Terminal 101 selects one of the transmission methods to transmit UCI based on service adaptation requirements, thereby improving the reliability and availability of service transmission.

[0185] In some embodiments, network device 102 may send a first signaling to terminal 101 when considering service adaptation requirements. The first signaling may configure or indicate the transmission method of UCI, which may include a transmission method adapted to the current service. Terminal 101 transmits UCI according to the transmission method, which improves the reliability and availability of service transmission.

[0186] In some embodiments, considering the flexibility of UCI transmission, the network device 102 can adjust the UCI transmission mode through the first signaling, for example, by changing from the first transmission mode to the second transmission mode or from the second transmission mode to the first transmission mode, so that the network can be configured more flexibly.

[0187] In some embodiments, network device 102 may carry configuration information in the first signaling to display the transmission method for configuring UCI.

[0188] For example, the first signaling can be RRC signaling.

[0189] For example, configuration information can occupy N bits, where N can be a positive integer.

[0190] For example, when N=1, network device 102 can explicitly configure the transmission mode of the UCI using one bit in the RRC signaling. For example, when the bit value of this bit is the first value, it can indicate that the configured UCI transmission mode is the first transmission mode; when the bit value of this bit is the second value, it can indicate that the configured UCI transmission mode is the second transmission mode. Here, the first value can be "1" and the second value can be "0", or the first value can be "0" and the second value can be "1".

[0191] For example, if the configuration information is not configured in the first signaling, that is, the transmission method of the UCI is not configured in the first signaling, the terminal 101 can determine the transmission method of the UCI based on the predefined method.

[0192] It is understood that the transmission mode configured for network device 102 may include a first transmission mode and a second transmission mode. Similarly, terminal 101 can determine the UCI transmission mode based on a predefined method, and this disclosure does not limit this.

[0193] For example, when N=2, network device 102 can explicitly configure the transmission mode of the UCI using two bits in the RRC signaling. For instance, if the first value of the two bits is "00", it indicates that the configured UCI transmission mode is the first transmission mode; if the second value is "01", it indicates that the configured UCI transmission mode is the second transmission mode; if the third value is "10", it indicates that the configured UCI transmission mode is both the first and second transmission modes; and if the fourth value is "11", the content represented or configured can be reserved.

[0194] The above is merely an illustrative example, and this disclosure does not limit the scheme of configuring the transmission mode of UCI by the network device 102 through the first signaling.

[0195] In one example, network device 102 may carry indication information in the first signaling to indicate the transmission method of UCI.

[0196] For example, the first signaling can be MAC CE.

[0197] For example, the indication information can occupy N bits, where N can be a positive integer.

[0198] For example, when N=2, the UCI transmission mode indicated by the two bits is as follows: when the value of the two bits is the first value, assuming it is "00", it can indicate the first transmission mode of UCI; when the value of the two bits is the second value, assuming it is "01", it can indicate the second transmission mode of UCI; when the value of the two bits is the third value, assuming it is "10", it can indicate the first and second transmission modes of UCI; when the value of the two bits is the fourth value, assuming it is "11", the indicated content can be reserved.

[0199] For example, for terminal 101, before receiving the first signaling, the transmission method of UCI can be determined based on a predefined method.

[0200] For example, network device 102 may pre-provide configurations for PUCCH and dedicated PUSCH. The dedicated PUSCH is a PUSCH specifically designated for transmitting UCI.

[0201] In one example, network device 102 may carry indication information in the first signaling to indicate the transmission method of UCI.

[0202] For example, the first signaling can be DCI.

[0203] The DCI may include, but is not limited to, at least one of UE-specific DCI, group common DCI, and common DCI, and this disclosure does not limit it.

[0204] Among them, the terminal-specific DCI can be specified for scheduling or indicating relevant information of the terminal, such as time-frequency domain resource location, modulation method, etc.

[0205] Among them, the group common DCI can be used to schedule or indicate relevant information of one or more terminals within the same terminal group.

[0206] The public DCI can be used to schedule relevant information for one or more terminals.

[0207] This disclosure does not limit the DCI format.

[0208] For example, the indication information can occupy N bits, where N can be a positive integer.

[0209] For example, when N=2, the UCI transmission mode indicated by the two bits is as follows: when the value of the two bits is the first value, assuming it is "00", it can indicate the first transmission mode of UCI; when the value of the two bits is the second value, assuming it is "01", it can indicate the second transmission mode of UCI; when the value of the two bits is the third value, assuming it is "10", it can indicate the first and second transmission modes of UCI; when the value of the two bits is the fourth value, assuming it is "11", the indicated content can be reserved.

[0210] For example, when the first signaling is DCI, this disclosure does not limit the bit position of the indication information in DCI.

[0211] For example, the information field containing the indication information can be a configurable information field in DCI, including but not limited to at least one of frequency domain resource allocation information field, time domain resource allocation information field, and specific information field, which this disclosure does not limit. The specific information field here can be an information field designated for indicating the UCI transmission mode.

[0212] For example, DCI can at least be used to indicate the transmission mode of UCI. In addition, DCI can also be used for the resource location of uplink and downlink transmission, the modulation mode of the terminal, etc. This disclosure does not limit the content indicated by DCI.

[0213] For example, for terminal 101, before receiving the first signaling, the transmission method of UCI can be determined based on a predefined method.

[0214] For example, network device 102 may pre-provide configurations for PUCCH and dedicated PUSCH. The dedicated PUSCH is a PUSCH specifically designated for transmitting UCI.

[0215] In some embodiments, network device 102 may send a first signaling message to terminal 101 when both dedicated PUSCH and PUCCH are configured, thereby configuring or indicating the transmission mode of UCI.

[0216] In some embodiments, network device 102 may send a first signaling to terminal 101 when it is necessary to dynamically indicate or adjust the transmission mode of UCI.

[0217] In some embodiments, network device 102 may send a first signaling to terminal 101 based on a request from terminal 101.

[0218] In some embodiments, network device 102 may send a first signaling to terminal 101 based on its own implementation and / or its own policies.

[0219] In some embodiments, network device 102 may send the first signaling to terminal 101 while configuring the uplink channel.

[0220] In some embodiments, step S2102 is an optional execution step. For example, if the terminal 101 and the network device 102 determine the UCI transmission method based on other methods, such as based on a predefined method, step S2102 may not be executed.

[0221] In step S2103, terminal 101 determines the transmission mode of UCI.

[0222] In some embodiments, terminal 101 may determine the UCI transmission method in, but is not limited to, the following ways:

[0223] Method 1: Determine the UCI transmission method based on a predefined method.

[0224] In one example, determining the UCI transmission method based on a predefined method may include, but is not limited to, determining the UCI transmission method based on protocol agreements.

[0225] In one example, the predefined method can be either the first transmission method or the second transmission method.

[0226] For example, if the protocol stipulates that UCI is transmitted based on the first transmission method, then terminal 101 determines that the transmission method of UCI is the first transmission method. Terminal 101 can then carry UCI through PUCCH and send the PUCCH carrying UCI to network device 102.

[0227] For example, if the protocol stipulates that UCI is transmitted based on the second transmission method, then terminal 101 determines that the transmission method of UCI is the second transmission method. Terminal 101 can subsequently carry UCI through a dedicated PUSCH and send the dedicated PUSCH carrying UCI to network device 102. The dedicated PUSCH only carries UCI and does not carry data.

[0228] For example, terminal 101 can determine the transmission mode of UCI based on a predefined method without receiving the first signaling sent by network device 102.

[0229] For example, terminal 101 can determine the transmission mode of UCI based on a predefined method when network device 102 does not send uplink channel configuration information.

[0230] For example, terminal 101 can determine the UCI transmission mode based on a predefined method when it is determined that the UCI transmission mode does not need to be determined based on the measurement value. Specifically, terminal 101 can determine that the UCI transmission mode does not need to be determined based on the measurement value when network device 102 is not configured with a threshold value associated with the measurement value.

[0231] The measured values ​​are obtained by measuring the signal quality and / or signal strength of the downlink information.

[0232] The downlink information includes, but is not limited to, downlink channels, such as at least one of the Physical Downlink Shared Channel (PDSCH) and Physical Downlink Control Channel (PDCCH).

[0233] The downlink information includes, but is not limited to, downlink signals, such as downlink reference signals, including, but not limited to, at least one of the following: Channel State Information-Reference Signal (CSI-RS); Positioning-Reference Signal (P-RS); Synchronization Signal / PBCH Block (SSB).

[0234] The downlink signal strength value can be measured by at least one of the following parameters: Reference Signal Receiving Power (RSRP) and Received Signal Strength Indication (RSSI).

[0235] The signal quality of downlink information can be measured by at least one of the following parameters: Reference Signal Receiving Quality (RSRQ), Signal to Noise Ratio (SNR), and Signal to Interference and Noise Ratio (SINR).

[0236] For example, this disclosure does not limit the effective timing of the UCI transmission mode determined based on a predefined method. For instance, after terminal 101 determines that the UCI transmission mode includes a first transmission mode based on a predefined method, it can determine the effective timing of the first transmission mode based on the predefined method and / or the indication of the network device. This disclosure does not limit the time unit in which the effective timing occurs.

[0237] Method 2: Determine the transmission method of UCI based on the first signaling.

[0238] In one example, the first signaling message carries configuration information, showing the UCI transmission method configured.

[0239] In one example, the first signaling message carries indication information indicating the transmission method of the UCI.

[0240] Accordingly, terminal 101 determines the transmission method of UCI based on the configuration information or indication information.

[0241] For example, configuration information occupies 1 bit. If the bit value is the first value, the UCI transmission mode is determined to be the first transmission mode. If the bit value is the second value, the UCI transmission mode is determined to be the second transmission mode. Here, the first value is "1" and the second value is "0", or the first value is "0" and the second value is "1".

[0242] For example, if the indication information occupies 2 bits, and the value of the 2 bits is "00", the terminal 101 can determine that the UCI transmission mode is the first transmission mode; if the value of the 2 bits is "01", the terminal 101 can determine that the UCI transmission mode is the second transmission mode; and if the value of the 2 bits is "10", the terminal 101 can determine that the UCI transmission mode is either the first transmission mode or the second transmission mode.

[0243] At this time, terminal 101 can use mode 1 to determine the transmission mode of the UCI based on a predefined mode.

[0244] In one example, if the first signaling does not configure or indicate the transmission mode of the UCI, for example, if the configuration information is defaulted or the indication signaling is defaulted, then terminal 101 can use mode 1 to determine the transmission mode of the UCI based on a predefined mode.

[0245] In one example, before receiving the first signaling, terminal 101 may use mode 1 to determine the transmission mode of the UCI based on a predefined mode.

[0246] In one example, the first signaling includes, but is not limited to, at least one of the following: RRC signaling; MAC CE; DCI; system message.

[0247] In one example, this disclosure does not limit the effective timing of the transmission mode of the UCI determined based on the first signaling. For example, the determined transmission mode of the UCI can take effect at any time unit after the terminal 101 successfully receives the first signaling, and this disclosure does not limit this.

[0248] Method 3: Determine the transmission mode of UCI based on uplink channel configuration information.

[0249] In one example, the uplink channel configuration information is used to configure the PUCCH, and terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode.

[0250] In one example, the uplink channel configuration information is used to configure a dedicated PUSCH, and terminal 101 can determine that the transmission mode of the UCI includes the second transmission mode.

[0251] In one example, the uplink channel configuration information is used to configure the PUCCH and dedicated PUSCH. Terminal 101 can use mode 1, based on a predefined mode, to determine the transmission mode of the UCI.

[0252] In one example, the uplink channel configuration information is used to configure the PUCCH and dedicated PUSCH. Terminal 101 can use mode 2 to determine the transmission mode of the UCI based on the first signaling.

[0253] In one example, this disclosure does not limit the effective timing of the transmission mode of the UCI determined based on the uplink channel configuration information. For example, the determined transmission mode of the UCI can take effect at any time unit after the terminal 101 successfully receives the uplink channel configuration information, and this disclosure does not limit this.

[0254] Method 4: Determine the transmission method of the UCI based on the measured values.

[0255] In one example, terminal 101 can determine the transmission mode of the UCI based on measurement values ​​when network device 102 is configured with both PUCCH and dedicated PUSCH.

[0256] In one example, terminal 101 can determine the transmission mode of the UCI based on the measurement value, provided that a threshold value (associated with the measurement value) is configured on network device 102.

[0257] In one example, terminal 101 can determine the transmission mode of the UCI based on the measured value, provided that a threshold value (associated with the measured value) has been determined in a predefined manner.

[0258] In one example, if the measured value is less than or equal to a threshold value, terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode. If the measured value is greater than the threshold value, terminal 101 can determine that the transmission mode of the UCI includes the second transmission mode.

[0259] The threshold value can be determined based on a predefined method and / or based on the configuration of the network device; the specific determination method is not limited in this disclosure.

[0260] The network device 102 can configure the threshold value through at least one of system messages, RRC signaling, MAC CE, and DCI. The system message may include, but is not limited to, System Information Block n (SIBn), where n can be a positive integer, such as 1, 2, 3, etc.

[0261] The measured values ​​are obtained by measuring the signal quality and / or signal strength of downlink information (including downlink channels and / or downlink signals), including but not limited to at least one of RSRP, RSRQ, RSSI, SINR, and SNR.

[0262] For example, if the measured value is RSRP#1 and the threshold value is RSRP#2, if RSRP#1 is less than or equal to RSRP#2, then terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode, that is, UCI is transmitted via PUCCH. If RSRP#1 is greater than RSRP#2, then terminal 101 can determine that the transmission mode of the UCI includes the second transmission mode, that is, UCI is transmitted via dedicated PUSCH.

[0263] In one example, if the measured value is less than or equal to a threshold value, terminal 101 can determine that the transmission mode of the UCI includes the second transmission mode. If the measured value is greater than the threshold value, terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode.

[0264] For example, if the measured value is RSSI#1 and the threshold value is RSSI#2, if RSSI#1 is less than or equal to RSSI#2, then terminal 101 can determine that the transmission mode of the UCI includes the second transmission mode, that is, UCI is transmitted through a dedicated PUSCH. If RSSI#1 is greater than RSSI#2, then terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode, that is, UCI is transmitted through a PUCCH.

[0265] In one example, if the measured value is less than or equal to a threshold value, terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. In this case, terminal 101 can use mode 1, based on a predefined mode, to determine the transmission mode of the UCI.

[0266] For example, if the measured value is SINR#1 and the threshold value is SINR#2, and if SINR#1 is less than or equal to SINR#2, then terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. Then terminal 101 can determine the transmission mode of the UCI based on a predefined mode, assuming it is the first transmission mode, that is, UCI is transmitted through PUCCH.

[0267] In one example, if the measured value is less than or equal to a threshold value, terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. In this case, terminal 101 can use mode 2, based on the first signaling, to determine the transmission mode of the UCI.

[0268] For example, if the measured value is SNR#1 and the threshold value is SNR#2, and if SNR#1 is less than or equal to SNR#2, then terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode and the second transmission mode. Then, based on the first signaling, terminal 101 can determine that the transmission mode of the UCI is assumed to be the second transmission mode, that is, the UCI is transmitted through a dedicated PUSCH.

[0269] In one example, if the measured value is greater than a threshold value, terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. In this case, terminal 101 can use mode 1, based on a predefined mode, to determine the transmission mode of the UCI.

[0270] For example, if the measured value is SINR#1 and the threshold value is SINR#2, and if SINR#1 is greater than SINR#2, then terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. Then terminal 101 can determine the transmission mode of the UCI based on a predefined mode, assuming it is the first transmission mode, that is, UCI is transmitted through PUCCH.

[0271] In one example, if the measured value is greater than a threshold value, terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. In this case, terminal 101 can use mode 2, based on the first signaling, to determine the transmission mode of the UCI.

[0272] For example, if the measured value is SNR#1 and the threshold value is SNR#2, and if SNR#1 is greater than SNR#2, then terminal 101 can determine that the transmission mode of the UCI includes a first transmission mode and a second transmission mode. Then, based on the first signaling, terminal 101 can determine that the transmission mode of the UCI includes the first transmission mode and the second transmission mode. Terminal 101 then determines the transmission mode of the UCI based on a predefined method, assuming it is the second transmission mode, that is, the UCI is transmitted through a dedicated PUSCH.

[0273] It is understandable that in Method 4, there is no restriction on the effective timing of the transmission method of UCI determined by terminal 101 based on the measurement value.

[0274] For example, the UCI transmission method determined by method 4 can take effect after terminal 101 determines the measurement value and successfully feeds back the measurement value to network device 102.

[0275] The above is merely an illustrative example, and this disclosure does not limit the scheme by which the terminal 101 determines the transmission method of UCI.

[0276] In step S2104, terminal 101 sends the measurement value to network device 102.

[0277] In some embodiments, network device 102 receives measurement values.

[0278] In some embodiments, terminal 101 can send measurement values ​​to network devices via measurement reports.

[0279] In some embodiments, step S2104 is an optional execution step. For example, if the terminal 101 and the network device 102 determine the transmission mode of UCI based on other methods, such as a predefined method, first signaling, or uplink channel configuration, step S2104 may not be executed.

[0280] In step S2105, network device 102 determines the transmission method of UCI.

[0281] In some embodiments, network device 102 may determine the UCI transmission method in, but is not limited to, the following ways:

[0282] Method 1: Determine the UCI transmission method based on a predefined method.

[0283] The specific determination method is similar to method 1 in step S2103, and will not be repeated here.

[0284] Method 2: Determine the transmission mode of the UCI based on the measured values.

[0285] Network device 102 can determine the transmission mode of the UCI based on the measurement value sent by terminal 101. The specific determination method is similar to mode 4 in step S2103, and will not be described again here.

[0286] Method 3: Determine the transmission method of the UCI based on its own implementation and / or its own strategy.

[0287] The above is merely an illustrative example, and this disclosure does not limit the scheme by which network device 102 determines the transmission method of UCI.

[0288] In one example, network device 102 determines the UCI transmission mode, including the first transmission mode, based on UCI transmission reliability.

[0289] In one example, network device 102, based on the complexity of terminal 101, determines the transmission method of UCI, including the second transmission method.

[0290] In one example, network device 102 determines the transmission method of UCI based on service adaptation requirements, including a first transmission method and a second transmission method, or, based on the current service, determines the transmission method of UCI to include a transmission method adapted to the current service.

[0291] In one example, network device 102 adjusts the UCI transmission method based on UCI transmission flexibility. For example, it may adjust from a first transmission method to a second transmission method or from a second transmission method to a first transmission method.

[0292] In one example, after network device 102 determines the transmission mode of UCI (e.g., using mode 3 to determine the transmission mode of UCI), it can configure or indicate the transmission mode of UCI through the first signaling. The specific method is similar to step S2102, and will not be described again here.

[0293] It is understood that if the transmission mode of the UCI determined by network device 102 includes a first transmission mode, then the first signaling can configure or indicate the first transmission mode. If the transmission mode of the UCI determined by network device 102 includes a second transmission mode, then the first signaling can configure or indicate the second transmission mode. If the transmission mode of the UCI determined by network device 102 includes both a first and a second transmission mode, then the first signaling can configure or indicate both the first and the second transmission modes. If the transmission mode of the UCI determined by network device 102 includes both a first and a second transmission mode, then the first signaling may not configure or indicate the transmission mode of the UCI.

[0294] In one example, after network device 102 determines the transmission method of UCI (e.g., using method 3 to determine the transmission method of UCI), it informs terminal 101 of the transmission method of UCI through uplink channel configuration information.

[0295] For example, if the transmission mode of the UCI determined by the network device 102 includes the first transmission mode, the uplink channel configuration information sent by the network device 102 to the terminal 101 can be used to configure the PUCCH.

[0296] For example, if the transmission mode of the UCI determined by the network device 102 includes the second transmission mode, the uplink channel configuration information sent by the network device 102 to the terminal 101 can be used to configure the dedicated PUSCH.

[0297] For example, if the transmission mode of the UCI determined by network device 102 includes a first transmission mode and a second transmission mode, the uplink channel configuration information sent by network device 102 to terminal 101 can be used to configure PUCCH and dedicated PUSCH. In some embodiments, the execution order of steps S2101, S2102, and S2105 is not limited. For example, network device 102 first executes step S2105 to determine the transmission mode of the UCI, and then executes step S2101 to send uplink channel configuration information to terminal 101, so that terminal 101 determines the transmission mode of the UCI based on the uplink channel configuration information. Another example is that network device 102 first executes step S2105 to determine the transmission mode of the UCI, and then executes step S2102 to configure or indicate the transmission mode of the UCI through the first signaling. Yet another example is that network device 102 first executes step S2101 to configure the uplink channel, and then executes step S2105 to determine the transmission mode of the UCI. For example, network device 102 first executes step S2101 to configure the uplink channel, and then executes step S2102 to configure or indicate the transmission mode of UCI through the first signaling.

[0298] In step S2106, terminal 101 sends a UCI to network device 102.

[0299] In some embodiments, terminal 101 sends the UCI to network device 102 according to the determined UCI transmission method.

[0300] In some embodiments, network device 102 receives the UCI according to the determined UCI transmission method.

[0301] It is understandable that when the UCI transmission method configured or indicated by the network device 102 through the first signaling includes the two transmission methods mentioned above, both the network device 102 and the terminal 101 can determine one of the transmission methods based on a predefined method, and perform UCI reception and transmission based on that transmission method.

[0302] Alternatively, if network device 102 configures both PUCCH and dedicated PUSCH through uplink channel configuration information, both network device 102 and terminal 101 can determine one of the transmission methods based on a predefined method and / or the first signaling, and perform UCI reception and transmission based on that transmission method.

[0303] Alternatively, if network device 102 and terminal 101 determine that the transmission mode of UCI includes the two transmission modes mentioned above based on the measurement value, both network device 102 and terminal 101 can determine one of the transmission modes based on the predefined mode and / or the first signaling, and perform UCI reception and transmission based on that transmission mode.

[0304] In other words, terminal 101 can send UCI to network device 102 using either the first or the second transmission method, and network device 102 can receive UCI using the corresponding transmission method, ensuring that terminal 101 and network device 102 have a consistent understanding of the UCI transmission method, thereby improving the reliability of UCI transmission.

[0305] In some embodiments, this disclosure does not limit the time-domain location at which the terminal 101 sends the UCI.

[0407] The dedicated PUSCH is the PUSCH specifically designated for transmitting UCI.

[0408] In this embodiment of the disclosure, there are no limitations on the time and frequency resources, transmission methods, configuration parameters, etc. of the dedicated PUSCH.

[0409] Methods for determining the transmission mode of UCI include at least one of the following:

[0410] Method 1: The terminal determines the specific method for transmitting uplink control information based on the explicit configuration information of the base station.

[0411] Explicit configuration information is carried through RRC signaling.

[0412] The explicit configuration information consists of N bits of indication information. In this patent, it is assumed that N = 1. Here, 0 indicates that UCI is transmitted using mode 1, and 1 indicates that UCI is transmitted using mode 2.

[0413] Furthermore, if this configuration information is left blank, either method 1 or method 2 will be used to transmit UCI by default.

[0414] Furthermore, the base station can also instruct the terminal to transmit UCI according to mode 1 and mode 2.

[0415] Method 2: The terminal determines the specific method for transmitting uplink control information based on the PUCCH configuration information and / or the dedicated PUSCH configuration information used for transmitting UCI provided by the base station.

[0416] If the base station only provides PUCCH configuration information, then UCI is transmitted according to method 1.

[0417] If the base station only provides dedicated PUSCH configuration information for transmitting UCI, then UCI is transmitted according to method 2.

[0418] If the base station provides both PUCCH configuration information and dedicated PUSCH configuration information for transmitting UCI, the specific method for transmitting UCI is determined according to a predefined method or other indication signaling.

[0419] Method 3: The terminal determines the specific method for transmitting uplink control information based on a predefined or base station-configured threshold value.

[0420] The threshold value is a threshold value for the relevant measurement value, including at least one of RSRP, RSRQ, RSSI, SNR, or SINR.

[0421] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0422] When the threshold value is configured through the base station, the configuration information is carried through SIB1 or RRC signaling.

[0423] In this embodiment of the disclosure, no limitation is made on the timing of the terminal determining the effective UCI transmission mode based on the threshold value.

[0424] Specifically, the UCI transmission method takes effect after the terminal obtains the measurement value and successfully feeds it back to the base station.

[0425] Method 4: The terminal determines the specific method of transmitting UCI after the control information carried by the MAC CE takes effect, based on the indication information carried by the base station through the MAC CE.

[0426] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0427] The MAC CE carries N bits of indication information.

[0428] The N-bit indication information is used to indicate at least one of the following transmission methods:

[0429] Transmit according to method 1;

[0430] Transmit according to method 2;

[0431] Transmit according to method 1 and method 2;

[0432] reserve.

[0433] Before the terminal detects and receives the MAC CE, it transmits the UCI according to a predefined method. The predefined method is as follows:

[0434] Transmit UCI according to method 1;

[0435] Alternatively, transmit the UCI according to method 2.

[0436] Method 5: The terminal determines the specific method of transmitting UCI based on the indication information carried by the base station through DCI.

[0437] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0438] The DCI is either UE-specific DCI, group common DCI, or common DCI; this patent does not impose any limitations on it.

[0439] This patent does not impose any restrictions on the DCI format.

[0440] The DCI carries N bits of indication information.

[0441] The N-bit indication information is used to indicate at least one of the following transmission methods:

[0442] Transmit according to method 1;

[0443] Transmit according to method 2;

[0444] Transmit according to method 1 and method 2;

[0445] reserve.

[0446] This disclosure does not impose any limitation on the bit position of the indication information in the aforementioned DCI.

[0447] Optionally, the indication information field is a configurable information field.

[0448] Before the terminal detects and receives the DCI, it transmits the UCI according to a predefined method. The predefined method is as follows:

[0449] Transmit UCI according to method 1;

[0450] Alternatively, transmit the UCI according to method 2.

[0451] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0452] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0453] In this disclosure, it is assumed that the uplink control information is carried through the uplink data channel.

[0454] In this disclosure, it is assumed that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel may be indicated by dynamic signaling or configured by semi-static signaling.

[0455] This disclosure does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0456] This disclosure does not impose any restrictions on the time slots (time domain locations) for transmitting dedicated PUSCH and / or PUCCH that carry UCI in the terminal transmission.

[0457] Base station side:

[0458] The base station determines how the terminal transmits uplink control information based on predefined rules or by instructing the terminal through explicit signaling.

[0459] The method of transmitting uplink control information includes at least:

[0460] Method 1: The terminal transmits the UCI via PUCCH.

[0461] In this embodiment of the disclosure, no limitations are made on the definition of PUCCH, time and frequency resources, physical layer structure, etc.

[0462] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0463] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0464] In this embodiment of the disclosure, no limitations are made on the time-frequency resources, transmission method, configuration parameters, etc. of the dedicated PUSCH.

[0465] Method 1: The base station sends explicit configuration information to the terminal to determine the specific method for transmitting uplink control information.

[0466] The explicit configuration information is carried through RRC signaling.

[0467] The explicit configuration information is N-bit indication information, and in this patent, it is assumed that N = 1. Wherein, 0 indicates that UCI is transmitted in mode 1 and 1 indicates that UCI is transmitted in mode 2.

[0468] Furthermore, if this configuration information is left blank, either method 1 or method 2 will be used to transmit UCI by default.

[0469] Furthermore, the base station can also instruct the terminal to transmit UCI according to mode 1 and mode 2.

[0470] Method 2: The base station determines the specific method by which the terminal transmits uplink control information based on the PUCCH configuration information provided to the terminal and / or the dedicated PUSCH configuration information used for transmitting UCI.

[0471] If the base station only provides PUCCH configuration information, then UCI is transmitted according to method 1.

[0472] If the base station only provides dedicated PUSCH configuration information for transmitting UCI, then UCI is transmitted according to method 2.

[0473] If the base station provides both PUCCH configuration information and dedicated PUSCH configuration information for transmitting UCI, the specific method for transmitting UCI is determined according to a predefined method or other indication signaling.

[0474] Method 3: The base station determines the specific method for the terminal to transmit uplink control information based on a predefined or configured threshold value.

[0475] The threshold value is a threshold value for the relevant measurement value, including at least one of RSRP, RSRQ, RSSI, SNR, or SINR.

[0476] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0477] When the threshold value is configured through the base station, the configuration information is carried through SIB1 or RRC signaling.

[0478] This disclosure does not impose any restrictions on the timing of the terminal determining the effective UCI transmission mode based on the threshold value.

[0479] Specifically, the UCI transmission method takes effect after the terminal obtains the measurement value and successfully feeds it back to the base station.

[0480] Method 4: The base station uses the indication information carried by the MAC CE to indicate the specific method by which the terminal transmits the UCI.

[0481] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0482] The MAC CE carries N bits of indication information.

[0483] The N-bit indication information is used to indicate at least one of the following transmission methods:

[0484] Transmit according to method 1;

[0485] Transmit according to method 2;

[0486] Transmit according to method 1 and method 2;

[0487] reserve.

[0488] Before the terminal detects and receives the MAC CE, it transmits the UCI according to a predefined method. The predefined method is as follows:

[0489] Transmit UCI according to method 1;

[0490] Alternatively, transmit the UCI according to method 2.

[0491] Method 5: The terminal instructs the terminal on the specific method of transmitting UCI based on the instruction information carried by the base station through DCI.

[0492] In this method, it is assumed that the base station provides both PUCCH-related configuration and dedicated PUSCH-related configuration for transmitting UCI.

[0493] The DCI is either UE-specific DCI, group common DCI, or common DCI; this patent does not impose any limitations on it.

[0494] This patent does not impose any restrictions on the DCI format.

[0495] The DCI carries N bits of indication information.

[0496] The N-bit indication information is used to indicate at least one of the following transmission methods:

[0497] Transmit according to method 1;

[0498] Transmit according to method 2;

[0499] Transmit according to method 1 and method 2;

[0500] reserve.

[0501] This disclosure does not impose any limitation on the bit position of the indicated information in the aforementioned DCI.

[0502] Optionally, the indication information field is a configurable information field.

[0503] Before the terminal detects and receives the DCI, it transmits the UCI according to a predefined method. The predefined method is as follows:

[0504] Transmit UCI according to method 1;

[0505] Alternatively, transmit the UCI according to method 2.

[0506] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0507] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0508] In this disclosure, it is assumed that the uplink control information is carried through the uplink data channel.

[0509] In this disclosure, it is assumed that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel may be indicated by dynamic signaling or configured by semi-static signaling.

[0510] This disclosure does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0511] This disclosure does not impose any restrictions on the time slots (time domain locations) for transmitting dedicated PUSCH and / or PUCCH that carry UCI in the terminal transmission.

[0512] Example 1: In this example, it is assumed that the terminal can send a UCI in two different ways. This example does not limit the type of UCI; the UCI can be at least one of HARQ-ACK, SR, CSI, etc. The two different ways of sending the UCI include:

[0513] Method 1: The terminal transmits the UCI via PUCCH.

[0514] This embodiment does not impose any limitations on the PUCCH, such as its format, time and frequency resources, physical layer structure, etc.

[0515] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0516] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0517] This embodiment does not impose any limitations on the dedicated PUSCH, such as time and frequency resources, transmission methods, configuration parameters, etc.

[0518] In this embodiment, it is assumed that the base station indicates the specific method of UCI transmission to the terminal via explicit signaling. For ease of description, this embodiment assumes that the base station only needs to indicate two UCI transmission methods, namely, method 1 and method 2. However, it should be noted that this method can also be directly extended to the selection and indication of more UCI transmission methods.

[0519] In this embodiment, it is assumed that the terminal receives the RRC signaling sent by the base station to determine the specific method for transmitting uplink control information. The explicit configuration signaling carried by the RRC signaling consists of N bits, which is assumed to be N=1 in this embodiment. Here, 0 indicates that mode 1 is used to transmit UCI, and 1 indicates that mode 2 is used to transmit UCI. Of course, the association between the indicator bit state and the corresponding UCI transmission mode can also be reversed, that is, 0 indicates that mode 2 is used to transmit UCI and 1 indicates that mode 1 is used to transmit UCI; this embodiment does not impose such a limitation.

[0520] Specifically, when the terminal receives configuration information from the base station and determines that it needs to send UCI according to method 1, the terminal sends UCI on the PUCCH. Of course, this method does not exclude the possibility of piggybacking the UCI to the PUSCH for transmission under certain conditions. For example, the UCI and data can be multiplexed and transmitted simultaneously on the PUSCH. Correspondingly, when the terminal receives configuration information from the base station and determines that it needs to send UCI according to method 2, the terminal sends UCI on the PUSCH.

[0521] It should be noted that this embodiment does not impose any limitations on resource selection, timing determination, or transmission method when the terminal sends UCI in a specific manner.

[0522] Furthermore, when the base station does not provide the terminal with the relevant configuration information indicating the UCI transmission method, the terminal transmits the UCI using the default method. The default method is either method 1 or method 2, and this patent does not specify which.

[0523] Furthermore, the base station can also instruct the terminal to transmit UCI using either Mode 1 or Mode 2. This embodiment does not impose any limitations on how the terminal selects Mode 1 or Mode 2 when actually transmitting UCI. For example, the transmission mode used for transmitting UCI can be determined through the implementation method.

[0524] Furthermore, the base station can also instruct the terminal on the specific method of transmitting UCI through broadcasting or multicasting, for example, by instructing the terminal on the specific method of transmitting UCI through the indication information carried in the SIB, which is not limited in this patent.

[0525] It should be noted that this patent does not impose any limitations on the following contents. The specific implementation methods of the following contents do not affect the execution of the method of this embodiment:

[0526] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0527] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0528] This embodiment assumes that when the uplink control information is carried through the uplink data channel, the uplink data channel is only used to carry UCI.

[0529] This embodiment assumes that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel can be indicated by dynamic signaling or configured by semi-static signaling.

[0530] This embodiment does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0531] This embodiment does not impose any limitations on the time slots for transmitting PUSCH and / or PUCCH that carry UCI.

[0532] Example 2: In this example, it is assumed that the terminal can send UCI in two different ways. This example does not limit the type of UCI; the UCI can be at least one of HARQ-ACK, SR, CSI, etc. The two different ways of sending UCI include:

[0533] Method 1: The terminal transmits the UCI via PUCCH.

[0534] This embodiment does not impose any limitations on the PUCCH, such as its format, time and frequency resources, physical layer structure, etc.

[0535] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0536] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0537] This embodiment does not impose any limitations on the dedicated PUSCH, such as time and frequency resources, transmission methods, configuration parameters, etc.

[0538] In this embodiment, it is assumed that the terminal determines the specific method for transmitting uplink control information based on the PUCCH configuration information and / or the dedicated PUSCH configuration information for transmitting UCI provided by the base station. For ease of description, this embodiment assumes that the base station only needs to indicate two UCI transmission methods, namely, method 1 and method 2. However, it should be noted that this method can also be directly extended to the selection and indication of more UCI transmission methods.

[0539] In this embodiment, it is assumed that the terminal receives RRC signaling sent by the base station. The RRC signaling provides PUCCH configuration information and / or dedicated PUSCH configuration information for transmitting UCI. If the base station only provides PUCCH configuration information, the UCI is transmitted according to method 1. If the base station only provides dedicated PUSCH configuration information for transmitting UCI, the UCI is transmitted according to method 2. If the base station provides both PUCCH configuration information and dedicated PUSCH configuration information for transmitting UCI, the specific method for transmitting UCI is determined according to a predefined method or other signaling indications. This embodiment does not limit the predefined method or other signaling indications. Of course, this embodiment does not exclude allowing the terminal to send UCI according to methods 1 and 2. The specific method used to send the UCI depends on the terminal implementation, and this embodiment does not impose any limitations.

[0540] It should be noted that this embodiment does not impose any limitations on resource selection, timing determination, or transmission method when the terminal sends UCI in a specific manner.

[0541] Furthermore, the base station can also instruct the terminal on the specific method of transmitting UCI through broadcasting or multicasting, for example, by instructing the terminal on the specific method of transmitting UCI through the indication information carried in the SIB, which is not limited in this patent.

[0542] It should be noted that this patent does not impose any limitations on the following contents. The specific implementation methods of the following contents do not affect the execution of the method of this embodiment:

[0543] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0544] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0545] This embodiment assumes that when the uplink control information is carried through the uplink data channel, the uplink data channel is only used to carry UCI.

[0546] This embodiment assumes that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel can be indicated by dynamic signaling or configured by semi-static signaling.

[0547] This embodiment does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0548] This embodiment does not impose any limitations on the time slots for transmitting PUSCH and / or PUCCH that carry UCI.

[0549] Example 3: In this example, it is assumed that the terminal can send UCI in two different ways. This example does not limit the type of UCI; the UCI can be at least one of HARQ-ACK, SR, CSI, etc. The two different ways of sending UCI include:

[0550] Method 1: The terminal transmits the UCI via PUCCH.

[0551] This embodiment does not impose any limitations on the PUCCH, such as its format, time and frequency resources, physical layer structure, etc.

[0552] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0553] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0554] This embodiment does not impose any limitations on the dedicated PUSCH, such as time and frequency resources, transmission methods, configuration parameters, etc.

[0555] In this embodiment, it is assumed that the base station provides the terminal with both PUCCH configuration information and dedicated PUSCH configuration information for transmitting UCI. The terminal determines the specific method for transmitting uplink control information based on a predefined or configured threshold value. For ease of description, this embodiment assumes that the base station only needs to indicate two UCI transmission methods, namely, method 1 and method 2. However, it should be noted that this method can also be directly extended to the selection and indication of more UCI transmission methods.

[0556] Specifically, the threshold value is determined through a predefined method in the protocol or through relevant configuration information provided by the base station. The type of configuration information used to provide the threshold value is not limited in this embodiment; for example, it could be RRC signaling or SIB. In this embodiment, it is assumed that the measurement value compared with the threshold value is at least one of RSRP, RSRQ, RRSI, SNR, or SINR; this embodiment does not impose any limitations. This patent does not limit how the terminal obtains the measurement value or what reference signal it uses for measurement.

[0557] Furthermore, this embodiment does not impose any limitations on the timing of the terminal determining the effective time of the UCI transmission mode based on the threshold value. For example, the effective time of the UCI transmission mode is after the terminal obtains the measurement value and successfully feeds it back to the base station.

[0558] Specifically, after obtaining the measured value, the terminal determines the specific method for transmitting the UCI based on a comparison between the measured value and the threshold value, i.e., transmitting the UCI according to method 1 or method 2. For example, when the measured value is higher than the threshold value, the UCI is transmitted according to method 2, and a PUSCH is selected from the dedicated PUSCHs provided by the base station for transmitting the UCI; when the measured value is lower than the threshold value, the UCI is transmitted according to method 1, and a PUCCH resource is selected from the PUCCHs provided by the base station for transmitting the UCI. This embodiment does not limit how the terminal selects the specific PUCCH resource or PUSCH resource for carrying the UCI.

[0559] It should be noted that this embodiment does not impose any limitations on resource selection, timing determination, or transmission method when the terminal sends UCI in a specific manner.

[0560] It should be noted that this patent does not impose any limitations on the following contents. The specific implementation methods of the following contents do not affect the execution of the method of this embodiment:

[0561] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0562] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0563] This embodiment assumes that when the uplink control information is carried through the uplink data channel, the uplink data channel is only used to carry UCI.

[0564] This embodiment assumes that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel can be indicated by dynamic signaling or configured by semi-static signaling.

[0565] This embodiment does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0566] This embodiment does not impose any limitations on the time slots for transmitting PUSCH and / or PUCCH that carry UCI.

[0567] Example 4: In this example, it is assumed that the terminal can send UCI in two different ways. This example does not limit the type of UCI; the UCI can be at least one of HARQ-ACK, SR, CSI, etc. The two different ways of sending UCI include:

[0568] Method 1: The terminal transmits the UCI via PUCCH.

[0569] This embodiment does not impose any limitations on the PUCCH, such as its format, time and frequency resources, physical layer structure, etc.

[0570] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0571] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0572] This embodiment does not impose any limitations on the dedicated PUSCH, such as time and frequency resources, transmission methods, configuration parameters, etc.

[0573] In this embodiment, it is assumed that the base station provides the terminal with both PUCCH configuration information and PUSCH configuration information for transmitting UCI. The terminal determines the specific method for transmitting uplink control information after the control information carried by the MAC CE takes effect, based on the indication information carried by the base station through the MAC CE. For ease of description, this embodiment assumes that the base station only needs to indicate two UCI transmission methods, namely, method 1 and method 2. However, it should be noted that this method can also be directly extended to the selection and indication of more UCI transmission methods.

[0574] In this embodiment, the MAC CE carries N bits of indication information to indicate the specific method of UCI transmission by the terminal. N is an integer greater than or equal to 1. In this embodiment, it is assumed that there are two possible methods for the terminal to transmit UCI, namely method 1 and method 2, therefore N = 1 or N = 2. Of course, this embodiment does not exclude other values ​​for N.

[0575] Taking N=1 as an example, the indication information is illustrated as follows:

[0576] 0 indicates that the terminal sends the UCI according to method 1;

[0577] 1 indicates that the terminal sends the UCI according to method 2.

[0578] Taking N=2 as an example, the indication information is illustrated as follows:

[0579] 00 indicates that the terminal sends the UCI according to method 1;

[0580] 01 indicates that the terminal sends the UCI according to method 2;

[0581] 10 indicates that the terminal can decide for itself whether to send the UCI using mode 1 or mode 2;

[0582] 11 indicates a reserved state.

[0583] Before the terminal detects and receives the MAC CE, or before the MAC CE takes effect, it transmits the UCI in a predefined manner. For example, it may transmit the UCI in mode 1 or mode 2; this embodiment does not impose any limitations.

[0584] The aforementioned MAC CE taking effect means that after the terminal sends an ACK to the base station for the PDSCH carrying the MAC CE, the terminal completes the parsing of the MAC CE.

[0585] It should be noted that this embodiment does not impose any limitations on resource selection, timing determination, or transmission method when the terminal sends UCI in a specific manner.

[0586] It should be noted that this patent does not impose any limitations on the following contents. The specific implementation methods of the following contents do not affect the execution of the method of this embodiment:

[0587] The physical resources used for transmitting uplink control information include at least one of time-domain resources, frequency-domain resources, code rate, transmission port, reference signal, and frequency hopping.

[0588] The uplink control information includes at least one of CSI, HARQ-ACK, and SR.

[0589] This embodiment assumes that when the uplink control information is carried through the uplink data channel, the uplink data channel is only used to carry UCI.

[0590] This embodiment assumes that the method for determining the uplink data channel used to carry uplink control information is not limited. For example, the uplink data channel can be indicated by dynamic signaling or configured by semi-static signaling.

[0591] This embodiment does not impose any restrictions on the configuration of candidate PUSCHs in the candidate PUSCH resource set.

[0592] This embodiment does not impose any limitations on the time slots for transmitting PUSCH and / or PUCCH that carry UCI.

[0593] Example 5: In this example, it is assumed that the terminal can send a UCI in two different ways. This example does not limit the type of UCI; the UCI can be at least one of HARQ-ACK, SR, CSI, etc. The two different ways of sending the UCI include:

[0594] Method 1: The terminal transmits the UCI via PUCCH.

[0595] This embodiment does not impose any limitations on the PUCCH, such as its format, time and frequency resources, physical layer structure, etc.

[0596] Method 2: The terminal transmits the UCI via a dedicated PUSCH.

[0597] The dedicated PUSCH is a PUSCH specifically used for transmitting UCI.

[0598] This embodiment does not impose any limitations on the dedicated PUSCH, such as time and frequency resources, transmission methods, configuration parameters, etc.

[0599] In this embodiment, it is assumed that the base station provides the terminal with both PUCCH configuration information and PUSCH configuration information for transmitting UCI. The terminal determines the specific method for transmitting uplink control information based on the indication information carried by the base station through DCI. For ease of description, this embodiment assumes that the base station only needs to indicate two UCI transmission methods, namely, method 1 and method 2. However, it should be noted that this method can also be directly extended to the selection and indication of more UCI transmission methods.

[0600] Method 5: The terminal determines the specific method of transmitting UCI based on the indication information carried by the base station through DCI.

[0601] In this method, it is assumed that the base station provides both PUCCH-related configuration and PUSCH-related configuration for transmitting UCI.

[0602] The DCI is either UE-specific DCI, group common DCI, or common DCI; this patent does not impose any limitations on it.

[0603] This patent does not impose any restrictions on the DCI format.

[0604] The DCI carries N bits of indication information.

[0605] The N-bit indication information is used to indicate at least one of the following transmission methods:

[0606] Transmit according to method 1;

[0607] Transmit according to method 2;

[0608] Transmit according to method 1 and method 2;

[0609] reserve.

[0610] This patent does not impose any limitation on the bit position of the indicated information in the aforementioned DCI.

[0611] Optionally, the indication information field is a configurable information field.

[0612] Before the terminal detects and receives the DCI, it transmits the UCI according to a predefined method. The predefined method is as follows:

[0613] Transmit UCI according to method 1;

[0614] Alternatively, transmit the UCI according to method 2.

[0615] In this embodiment, the DCI carries N bits of indication information to indicate the specific method by which the terminal transmits the UCI. The DCI can be a UE-specific DCI, a group common DCI, or a common DCI; this embodiment does not impose any limitations. N is an integer greater than or equal to 1. In this embodiment, it is assumed that there are two possible methods for the terminal to transmit the UCI, namely method 1 and method 2; therefore, N = 1 or N = 2. Of course, this embodiment does not exclude other values ​​for N.
