[0004] Uplink control information refers to information sent from the terminal to the control network-side equipment, transmitted through a specific uplink channel. Uplink control information is typically used to provide feedback on channel quality, report current status, and improve communication throughput and latency between the network-side equipment and the terminal. The applications of uplink control information are wide-ranging, including but not limited to control signals in communication protocols and observation results in statistical data. This information is crucial for improving the overall observation of the system and ensuring effective communication.

The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0065] To facilitate understanding of the uplink control information transmission method in the embodiments of this application, the following related content will be introduced first:

[0066] 1. Timing for Hybrid Automatic Repeat Request Acknowledge (HARQ-ACK) character.

[0067] HARQ-ACK timing is defined as the interval between the end of downlink data reception and the corresponding ACK / Negative Acknowledgement (NACK) feedback. NR supports flexible HARQ-ACK timing configuration and indication to adapt to different service and network deployments. Each UE can configure a UE-specific HARQ-ACK timing set through Radio Resource Control (RRC). This set contains multiple HARQ-ACK timing values, i.e., K1 values, where K1 is in units of time slots. When the base station dynamically schedules downlink data transmission, it indicates a K1 value in the DCI using an index. This K1 is a value in the UE-specific HARQ-ACK timing set, used to inform the UE of the time interval from receiving downlink data to feeding back a HARQ-ACK.

[0068] II. HARQ-ACK codebook

[0069] For HARQ-ACK procedures that support Transport Block (TB) level feedback, each TB corresponds to one HARQ-ACK bit. The UE needs to indicate its minimum HARQ processing time capability (the minimum HARQ processing time is the minimum time required to receive the corresponding HARQ-ACK transmission timing from downlink data). Asynchronous and adaptive downlink HARQ are supported for Enhanced Mobile Broadband (eMBB) and Ultra Reliable & Low Latency Communication (URLLC). From the UE's perspective, HARQ-ACK feedback from multiple Physical Downlink Shared Channels (PDSCH) can be transmitted in time within a single uplink (UL) data / control area, constituting a HARQ-ACK codebook on this UL time resource. The timing between PDSCH reception and the corresponding ACK / NACK is specified in the DCI (see the PDCSCH to HARQ timing indicator in Downlink Control Information (DCI) format 1_0 and DCI format 1_1).

[0070] The 15th version of the NR protocol (R15) supports two types of HARQ-ACK codebooks: type-1: semi-static HARQ-ACK codebook and type-2: dynamic HARQ-ACK codebook.

[0071] For the semi-static HARQ-ACK codebook, the UE determines all the PDSCHs that may be fed back in a certain time slot based on parameters such as the monitoring occasion of the Physical Downlink Control Channel (PDCCH) configured by RRC, the time domain resource allocation of PDSCH, and the feedback timing from PDSCH to HARQ-ACK (dl-DataToUL-ACK or PDSCH-toHARQ-timing), thereby determining the HARQ-ACK codebook. Since it may include HARQ-ACK feedback from both actually scheduled and unscheduled PDSCHs, its codebook is generally quite large.

[0072] For dynamic HARQ-ACK codebooks, the UE determines the HARQ-ACK codebook based on the actually scheduled PDSCH. Since feedback is only provided to the actually scheduled PDSCH, the codebook size for dynamic HARQ-ACK is usually smaller than that of semi-static HARQ-ACK codebooks. The specific type of codebook used by the UE is determined through RRC configuration.

[0073] III. Method for determining PUCCH resources:

[0074] In Release 15 (R15), the base station can configure one or more (up to four) Physical Uplink Control Channel Resource Sets (PUCCH resource sets) for each UE via RRC signaling. The RRC configuration or predefined maximum number of bits of Uplink Control Information (UCI) payload that each resource set (RESET) can carry (e.g., the first RESET has a maximum of 2 bits, the second and third RESETs have n1 and n2, and the fourth RESET has a maximum of 1706 bits, where n1 and n2 are configured by the RRC signaling). Each RESET can contain multiple PUCCH resources (the first RESET can contain a maximum of 32 PUCCH resources, and each of the other RESETs can contain a maximum of 8 PUCCH resources).

[0075] On the UE side, after receiving a PDSCH, the UE needs to send back a HARQ-ACK. To determine the PUCCH resource where the HARQ-ACK is sent, the UE first needs to determine the slot of the PUCCH by using K1 in the PDCCH that schedules the PDSCH. Then, it needs to determine the RESET where the PUCCH is located by the number of bits of the HARQ-ACK that needs to be sent back. Within the determined RESET, the UE determines which specific PUCCH resource within the RESET is based on the PUCCH resource indicator (PRI) field of the PDCCH (when the RESET contains no more than 8 resources) or the index of PRI + the first control channel resource element (CCE) of the PDCCH (when the RESET contains more than 8 resources). When multiple PDSCH HARQ-ACKs are sent back in one slot, the UE determines the PUCCH resource based on the PRI and the smallest CCE index in the last DCI that schedules these PDSCHs.

[0076] It should be noted that the uplink control information transmission method in this application embodiment can be used before or after the RRC connection is established.

[0077] The uplink control information transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0078] As shown in Figure 2, an embodiment of this application provides an uplink control information transmission method, which may include the following steps 201 or 202:

[0079] Step 201: With the uplink control channel closed, the terminal sends uplink control information through the uplink shared channel.

[0080] The uplink control channel can be PUCCH.

[0081] Uplink Control Information (UCI) may include at least one of the following: feedback information of the first downlink channel (e.g., HARQ-ACK of PDSCH), channel state information (CSI); CSI may include at least one of the following: rank indicator (RI), pre-coding matrix indicator (PMI), channel quality indicator (CQI), cross-link interference (CLI) information, and sensing results.

[0082] Step 202: When the uplink control channel is enabled, the terminal sends the uplink control information through at least one of the uplink shared channel and the uplink control channel.

[0083] The uplink shared channel can be the Physical Uplink Shared Channel (PUSCH).

[0084] As shown in steps 201 to 202, in this embodiment, when the uplink control channel is closed, the terminal can send uplink control information through the uplink shared channel; when the uplink control channel is open, the terminal can send uplink control information through at least one of the uplink shared channel and the uplink control channel. Therefore, in this embodiment, the uplink control channel can be opened or closed. When the uplink control channel is closed, uplink control information is transmitted through the uplink shared channel; when the uplink control channel is open, uplink control information is transmitted through at least one of the uplink shared channel and the uplink control channel. Thus, in this embodiment, the uplink control channel can be flexibly opened or closed under different situations or scenarios, thereby selecting the appropriate channel to transmit uplink control information, thus meeting different transmission requirements of uplink control information and achieving more flexible uplink control information transmission.

[0085] For example, if the terminal does not support uplink control channel transmission of uplink control information, the uplink control channel can be turned off, and the terminal can then send uplink control information through the uplink shared channel (for example, some capability levels of terminals can turn off the uplink control channel). If the terminal supports uplink control channel transmission of uplink control information, the terminal can turn on the uplink control channel (for example, some other capability levels of terminals can turn on the uplink control channel), thereby sending uplink control information through at least one of the uplink shared channel and the uplink control channel. Furthermore, leakage to neighboring channels can be reduced.

[0086] It is understandable that whether to enable the uplink control channel can be determined based on at least one of the following:

[0087] The terminal's capabilities in different scenarios (e.g., whether it supports uplink control channel transmission of uplink control information in different scenarios);

[0088] The type of uplink control information to be fed back (e.g., uplink control information of type A needs to be carried in the uplink control channel, and uplink control information of type B needs to be carried in the uplink shared channel; if the uplink control information to be fed back currently includes both type A and type B uplink control information, then the uplink control channel needs to be enabled, so that uplink control information of type A is sent through the uplink control channel and uplink control information of type B is sent through the uplink shared channel);

[0089] The priority of the uplink control information to be fed back (for example, high-priority uplink control information needs to be carried in the uplink control channel, and low-priority uplink control information needs to be carried in the uplink shared channel. If the uplink control information to be fed back at present includes both high-priority and low-priority uplink control information, then the uplink control channel needs to be enabled, so that high-priority uplink control information is sent through the uplink control channel and low-priority uplink control information is sent through the uplink shared channel).

[0090] The payload of the required uplink control information (e.g., uplink control information less than Z bits needs to be carried in the uplink control channel, uplink control information greater than or equal to Z bits needs to be carried in the uplink shared channel; if the current required uplink control information is greater than Z bits, then the uplink control channel needs to be enabled).

[0091] In addition, the following problems exist when transmitting HARQ-ACK via PUCCH:

[0092] 1. Reuse leads to changes in load, which in turn leads to changes in resources:

[0093] As shown in Figure 3, when a DCI schedules a PDSCH, the PDSCH will send back a HARQ-ACK, meaning the DCI will indicate a HARQ resource, i.e., resource 0. Resource 0 overlaps with a Scheduling Request (SR) resource. Normally, the HARQ-ACK should reuse the SR using a resource set determined by the DCI. If the SR's payload causes a change in the resource set, the UE will select a neighboring resource set to determine the resource, i.e., reuse resource 1. If resource 1 overlaps with a CSI resource, then HARQ, SR, and CSI need to be reused to obtain resource 2. It should be noted that the CSI's payload may cause a change in the resource set, and resource 2 may belong to a different resource set.

[0094] Therefore, when HARQ and SR resources overlap, a new resource 1 needs to be determined based on the sum of the loads of HARQ and SR; then the last used resource (i.e., resource 1) is different from the resource indicated by DCI, i.e., resource movement occurs; if resource 1 overlaps with CSI resources, a new resource, i.e., resource 2, needs to be determined based on the sum of the loads of HARQ, RS, and CSI; resource movement may occur again.

[0095] Alternatively, as shown in Figure 4, DCI 1 indicates HARQ-ACK 1, which is transmitted using resource 1 in resource set 1. Subsequently, DCI 2 indicates HARQ-ACK 2, but the UE reuses HARQ-ACK 1 and HARQ-ACK 2 using resource 2 in resource set 2 for transmission. DCI 3 indicates HARQ-ACK 3, but due to payload changes, resources in resource set 3 are needed to transmit HARQ-ACK 1, 2, and 3. It can be seen that each DCI may change the corresponding PUCCH resource.

[0096] It is evident that when transmitting HARQ-ACK via PUCCH, multiplexing transmission can lead to payload changes, resulting in changes to the resource set and resources. These resource changes increase the complexity of HARQ-ACK transmission via PUCCH.

[0097] 2. The issue of low-priority channels being cancelled:

[0098] As shown in Figure 5, the low-priority (LP) DCI schedules LP PUCCH; then, the high-priority (HP) DCI schedules HP HARQ1. HARQ1 overlaps with SR, and when multiplexed together, the HP intermediate feedback resource PUCCH1 is selected. Since the resources of HP intermediate PUCCH1 overlap with LP PUCCH, the transmission of LP PUCCH is cancelled. Subsequently, HP DCI2 schedules HARQ2, and the resources carried by HP intermediate PUCCH1 will be multiplexed with HARQ2. Thus, HARQ1, SR, and HARQ2 are multiplexed onto HP intermediate PUCCH2. Afterward, HP PUSCH is scheduled through HP DCI 3. The resources of HP intermediate PUCCH2 overlap with HP PUSCH, and HARQ1, SR, HARQ2, and HP PUSCH are multiplexed onto HP PUSCH resources. It should be noted that there is no PUCCH transmission at this time. However, the LP PUCCH and the high-priority PUSCH do not overlap. The LP PUCCH does not need to be canceled, but the intermediate process of the high-priority PUCCH multiplexing is canceled, which leads to the unnecessary cancellation of the LP channel.

[0099] In this embodiment, when the uplink control channel is PUCCH and the uplink shared channel is PUSCH, UCI (e.g., HAQR-ACK) can be transmitted via PUSCH when PUCCH is closed. Since the time-domain location of the network-side configured resources does not change due to load variations during PUSCH transmission, the problem of load changes and resource changes caused by multiplexing during HARQ-ACK transmission via PUCCH is avoided, thus reducing the complexity of UCI processing. Furthermore, transmitting UCI via PUSCH when PUCCH is closed eliminates the overlap between PUSCH and PUCCH, thereby reducing the probability of cancellation of the low-priority channel mentioned above.

[0100] Furthermore, in the embodiments of this application, when the terminal feeds back uplink control information via PUCCH, if PUCCH overlaps with a PUSCH, then the UCI carried by PUCCH will be multiplexed onto the PUSCH, and PUCCH will not be transmitted at this time.

[0101] Optionally, the method further includes one of the following A1-1 to A1-2:

[0102] Item A1-1: When the terminal receives the first configuration information and the first configuration information indicates that the uplink control channel should be turned off, the terminal turns off the uplink control channel;

[0103] Item A1-2: When the terminal receives the first configuration information and the first configuration information indicates that the uplink control channel should be enabled, or when the terminal is not configured with the first configuration information, the terminal enables the uplink control channel.

[0104] Therefore, the network-side device can configure the terminal with first configuration information to indicate whether to enable or disable the uplink control channel. In this case, the first configuration information can be used to indicate either enabling or disabling the uplink control channel.

[0105] Alternatively, the network-side device can send first configuration information to the terminal to disable the uplink control channel. In this case, the first configuration information indicates that the uplink control channel is disabled. If the network-side device does not send the first configuration information to the terminal, the terminal assumes that the uplink control channel is enabled. That is, even if the network-side device does not configure the first configuration information, the terminal can assume that the uplink control channel is enabled.

[0106] It is understandable that the network-side device can send first configuration information to the terminal to indicate that the uplink control channel is enabled. In this case, the first configuration information indicates that the uplink control channel is enabled. If the network-side device does not send the first configuration information to the terminal, the terminal assumes that the uplink control channel is disabled. Alternatively, the terminal can also assume that the uplink control channel is disabled even if the network-side device does not configure the first configuration information.

[0107] Furthermore, the aforementioned enabling of the uplink control channel can be understood as enabling uplink channel transmission of UCI; disabling the uplink control channel can be understood as disabling uplink control channel transmission of UCI.

[0108] As shown in steps 201 to 202, the terminal can transmit UCI through the uplink shared channel, the uplink control channel, or both. The following sections will describe the relevant aspects of UCI transmission from these three perspectives.

[0109] First aspect: Transmitting UCI via the uplink shared channel:

[0110] Optionally, in step 201 above, the terminal sends uplink control information through the uplink shared channel, including the following steps B-1 to B-3:

[0111] Step B-1: The terminal receives second configuration information, wherein the second configuration information is used to configure a configuration-authorized uplink shared channel for transmitting the uplink control information;

[0112] Step B-2: The terminal determines the first target resource of the configured authorized uplink shared channel based on the second configuration information;

[0113] Step B-3: When the first target resource and the second target resource do not overlap in the time domain, the terminal sends the uplink control information through the first target resource, wherein the second target resource includes resources for dynamically authorized uplink shared channels.

[0114] Therefore, it can be seen that network-side devices can configure a Configured Grant (CG) uplink shared channel for the terminal to transmit uplink control information, so that when the uplink control channel is turned off, the terminal can transmit UCI through the CG uplink shared channel.

[0115] Among them, transmitting UCI through the CG uplink shared channel can simplify the multiplexing process of UCI transmission on the UE side, thereby simplifying the complexity of network and UE implementation and reducing power consumption.

[0116] It is understandable that after the terminal determines the first target resource of the CG uplink shared channel for transmitting UCI based on the second configuration information mentioned above, if the first target resource does not overlap with the resources of the Dynamic Grant (DG) uplink shared channel, then UCI can be transmitted through the first target resource.

[0117] Optionally, in step B-2, the terminal determines the first target resource of the configured authorized uplink shared channel based on the second configuration information, including:

[0118] The terminal determines the minimum number of physical resource blocks required to satisfy the code rate based on the number of bits in the uplink control information.

[0119] The terminal determines the first target resource based on the minimum number of physical resource blocks and the second configuration information.

[0120] The terminal can determine the frequency domain resources for transmitting uplink control information by constructing a codebook for uplink control information.

[0121] In addition, different numbers of uplink control information bits can correspond to different minimum PRB numbers. For example, as shown in Figure 7, when the number of uplink control information bits x is less than or equal to M1, the minimum PRB number is PRB number A; when it is greater than M1 and less than or equal to M2, the minimum PRB number is PRB number B; when it is greater than M2 and less than or equal to M3, the minimum PRB number is PRB number C.

[0122] The following is a detailed description of the contents included in the second configuration information, as described in both semi-static and dynamic configuration sections:

[0123] I. Semi-static configuration:

[0124] Optionally, the second configuration information includes at least one of the following C-1 to C-2:

[0125] C-1: First indication information, used to indicate the format of the configured authorized uplink shared channel, wherein the format of the configured authorized uplink shared channel includes a first format and a second format, the first format is used to indicate that the configured authorized uplink shared channel transmits the uplink control information but does not transmit data, and the second format is used to indicate that the configured authorized uplink shared channel can transmit the uplink control information and data simultaneously;

[0126] It should be noted that the CG uplink shared channel transmits UCI but not data; this can be understood as the CG uplink shared channel only transmitting UCI.

[0127] C-2: Codebook type indicator, used to indicate the codebook type of UCI carried on the CG uplink shared channel.

[0128] Optionally, the second configuration information may further include at least one of the following items C-3 to C-13 of the CG uplink shared channel:

[0129] C-3: Time Domain Offset;

[0130] C-4: Time Domain Allocation;

[0131] Item C-5: Frequency Domain Allocation;

[0132] Item C-6: Antenna Port;

[0133] Item C-7: Demodulation Reference Signal (DMRS) sequence initialization (dmrs-SeqInitialization);

[0134] C-8 item: precoding and number of layers;

[0135] Item C-9: Sounding Reference Signal (SRS) Resource Indicator;

[0136] Item C-10: Modulation and coding strategy and transport block size (mcsAndTBS);

[0137] Item C-11: Frequency Hopping Offset;

[0138] Item C-12: Path Loss Reference Index;

[0139] Item C-13: Physical layer priority index (phy-PriorityIndex).

[0140] It should be noted that at least one of the information items in C-1 to C-13 above can be configured semi-statically, that is, it belongs to semi-static configuration information, so as to meet at least one of the requirements of UCI transmission in terms of transmission delay and reliability.

[0141] In addition, after receiving the second configuration information including at least one of C-1 to C-13 above, the terminal still needs to construct a codebook to determine the number of bits of UCI, and then determine the first target resource of the CG uplink shared channel used to carry UCI based on the number of bits of UCI and the second configuration information.

[0142] II. Dynamic Configuration

[0143] Optionally, the second configuration information further includes at least one of the following D-1 to D-4:

[0144] Item D-1: Transmission parameters for the configuration-authorized uplink shared channel used to transmit the uplink control information;

[0145] The transmission parameters of the uplink shared channel may include at least one of the following:

[0146] Configuration authorization for transmitting the uplink control information includes power control information (e.g., transmit power control, TPC) on the uplink shared channel;

[0147] Waveform indication information for the configuration-authorized uplink shared channel used to transmit the uplink control information;

[0148] The configuration authorization uplink shared channel frequency hopping indication information used to transmit the uplink control information.

[0149] Item D-2: The type of uplink control information carried on the configuration authorization uplink shared channel for transmitting the uplink control information; wherein, the UCI type may include at least one of the following: feedback information of the first downlink channel (e.g., HARQ-ACK of PDSCH), CSI, and CSI including RI, PMI, CQI, CLI information, and at least one of the following: sensing results;

[0150] D-3: First interval, wherein, when the uplink control information includes feedback information of the first downlink channel, the first interval is used to indicate a time unit of interval between the first downlink channel and the configured authorized uplink shared channel;

[0151] Item D-4: Index of the configuration-authorized uplink shared channel used to transmit the uplink control information.

[0152] It should be noted that at least one of the information items D-1 to D-4 above can be dynamically configured, that is, it belongs to dynamic configuration information, thereby flexibly configuring the transmission parameters of the PUSCH carrying UCI, better matching the characteristics of the channel, and meeting at least one of the requirements of UCI transmission in terms of transmission delay and reliability.

[0153] Optionally, the index of the configuration-granted uplink shared channel used to transmit the uplink control information corresponds to at least one of the following:

[0154] The format of the configuration-authorized uplink shared channel used to transmit the uplink control information may include the first format and the second format described above.

[0155] The start symbol of the configuration-authorized uplink shared channel used for transmitting the uplink control information;

[0156] The number of continuous symbols for the configuration-authorized uplink shared channel used to transmit the uplink control information.

[0157] Therefore, the index of each CG uplink shared channel can be associated with at least one of the following: the format, start symbol, and number of continuous symbols of the CG uplink shared channel.

[0158] Optionally, if the uplink control information includes feedback information of the first downlink channel, the second configuration information is carried on the downlink control information (DCI) that schedules the first downlink channel.

[0159] For example, as shown in Figure 6, the downlink (DL) DCI schedules the PDSCH. This DL DCI can carry the second configuration information mentioned above, used to indicate the CG PUSCH carrying UCI. This DCI can also indicate the use of the DG PUSCH to carry UCI. It should be noted that the transmission parameters of the CG PUSCH can be configured by the network, and the transmission parameters of the DG PUSCH can be determined by at least one of the two methods: network configuration or DCI indication.

[0160] Optionally, the method further includes:

[0161] The terminal sends its data scheduling request through a configured authorized uplink shared channel.

[0162] It should be noted that the configuration method for the CG uplink shared channel used to carry terminal scheduling requests (SRs) can be the same as the configuration method for the CG uplink shared channel used to carry UCIs described above. For example, the type of SR can be explicitly represented by 1 bit UCI, where 0 represents a negative SR, i.e., no scheduling request, and 1 represents a positive SR, i.e., a scheduling request exists.

[0163] In addition, the CG uplink shared channel used to carry terminal scheduling requests (SRs) can be the same as or different from the CG uplink shared channel used to carry UCIs.

[0164] For example, CG PUSCH is only sent in a positive SR, and not in a negative SR. The CG PUSCH can carry virtual padding bits, which can be generated by the physical layer or the MAC layer.

[0165] When a positive SR resource overlaps with a PUSCH carrying a HARQ-ACK, the HARQ-ACK transmission can use the SR's resource (CG PUSCH) for transmission. When a negative SR resource overlaps with a PUSCH carrying a HARQ-ACK, the HARQ-ACK transmission can use its own resource (CG PUSCH) for transmission.

[0166] When the PUSCH resource carrying CSI overlaps with the PUSCH resource carrying HARQ-ACK, CSI can be transmitted using either the resource (CG PUSCH) where HARQ-ACK is transmitted or the resource (CG PUSCH) where CSI is transmitted. The choice of which method to use is configurable by the network.

[0167] Optionally, in step 201 above, the terminal sends uplink control information through the uplink shared channel, including the following steps E-1 to E-3:

[0168] Step E-1: The terminal receives third configuration information, wherein the third configuration information is used to indicate the codebook type;

[0169] Step E-2: The terminal determines the target codebook of uplink control information carried on the Dynamic Licensed Uplink Shared Channel based on the third configuration information;

[0170] Step E-3: The terminal sends the uplink control information through the dynamic authorization uplink shared channel according to the target codebook.

[0171] Therefore, it can be seen that network-side equipment can also configure third configuration information for the terminal to indicate the codebook type, so that the terminal can determine the target codebook of UCI carried on the DG uplink shared channel according to the codebook type indicated by the third configuration information, and then the terminal can send UCI through the DG uplink shared channel according to the target codebook.

[0172] Wherein, if the uplink control information includes feedback information from the first downlink channel, in step E-2, the terminal determines the target codebook (i.e., the target codebook of the feedback information from the first downlink channel) of the uplink control information carried on the dynamically licensed uplink shared channel according to the third configuration information, including:

[0173] When the second information field indicating the codebook type in the third configuration information is empty, the codebook type carried on the dynamically scheduled uplink shared channel is the same as the codebook type to be carried on the overlapping configuration-granted uplink shared channel; that is, if the DG uplink shared channel overlaps with the CG uplink shared channel carrying UCI, the UCI on the CG uplink shared channel will be carried on the DG uplink shared channel. Here, the empty value indicates that the codebook type is the same as the type of the overlapping CG uplink shared channel; for example, the CG PUSCH carries the Type 2 HARQ-ACK codebook type, but the overlapping DG PUSCH indicates the Type 1 HARQ-ACK codebook type, then the UE uses the Type 1 HARQ-ACK codebook type to transmit on the DG PUSCH.

[0174] When the uplink control information includes feedback information of the first downlink channel and the second information field is codebook type one (i.e., semi-static HARQ codebook), the codebook type carried on the dynamically scheduled uplink shared channel is type 1 HARQ-ACK codebook (i.e., Type-1 HARQ-ACK codebook).

[0175] When the uplink control information includes feedback information of the first downlink channel and the first information field is codebook type 2 (i.e., dynamic HARQ codebook), the codebook type carried on the dynamically scheduled uplink shared channel is type 2 HARQ-ACK codebook (i.e., Type-2 HARQ-ACK codebook).

[0176] When the uplink control information includes feedback information of the first downlink channel, and the first information field is codebook type three (i.e., codebook that feeds back HARQ according to the configured number of carriers or processes), the codebook type carried on the dynamically scheduled uplink shared channel is type 3 HARQ-ACK codebook (i.e., Type-3 HARQ-ACK codebook).

[0177] Among them, the null values, types one, two, and three mentioned above are used for the transmission of feedback information in the first downlink channel.

[0178] When the uplink control information includes CSI, the CSI can be transmitted using a predefined or indicated method.

[0179] Optionally, the third configuration information is carried on the DCI that schedules the dynamically authorized uplink shared channel.

[0180] Therefore, it can be seen that by scheduling the DCI of the DG uplink shared channel, it is possible to indicate how to reuse a UCI, where the UCI may be the UCI carried by the CG uplink shared channel that overlaps with the DG uplink shared channel or a new UCI type.

[0181] It should be noted that the HARQ-ACK codebook indicated by the second information above should include at least the entire payload of the HARQ-ACK to be transmitted on the CG PUSCH.

[0182] Furthermore, by reusing the UCI carried on the CG PUSCH, the uplink transmission can maintain the single-carrier transmission characteristic, ensuring the performance of the terminal's uplink transmission.

[0183] It should be noted that the DG PUSCH and CG PUSCH mentioned above need to be restricted to one carrier. For terminals that support multiple PUSCH transmissions on multiple carriers, the terminal can transmit PUSCH on one carrier and transmit PUSCH carrying UCI on another carrier.

[0184] The above content describes a method for transmitting UCI via the CG uplink shared channel when the resources of the CG uplink shared channel (i.e., the first target resource mentioned above) and the resources of the DG uplink shared channel (i.e., the second target resource) carrying UCI do not overlap in the time domain. It also describes a method for transmitting UCI via the DG uplink shared channel when the resources of the CG uplink shared channel (i.e., the first target resource mentioned above) and the resources of the DG uplink shared channel (i.e., the second target resource) overlap in the time domain and the processing timeline requirements (i.e., the first timeline requirements) are met. The following section further describes a method for transmitting UCI when the two resources overlap in the time domain, taking into account the processing timeline requirements (i.e., the first timeline requirements).

[0185] Optionally, the method further includes the following step F-1:

[0186] Step F-1: When the first target resource and the second target resource overlap in the time domain, the terminal transmits at least one of the uplink control information on the first target resource and the dynamically authorized uplink shared channel, based on the satisfaction of the first timeline requirement when the uplink control information on the first target resource is multiplexed onto the second target resource.

[0187] When the resources of the CG uplink shared channel carrying UCI overlap with those of the DG uplink shared channel, it is possible to consider multiplexing the UCI on the CG uplink shared channel to the DG uplink shared channel. However, when multiplexing, it is necessary to consider whether the first timeline requirement is met, and then select to transmit one or both of the CG uplink shared channel and the DG uplink shared channel.

[0188] Furthermore, the first timeline requirement represents: processing latency requirements related to terminal capabilities; meeting the first timeline requirement means meeting the processing latency requirements related to terminal capabilities; not meeting the first timeline requirement means not meeting the processing latency requirements related to terminal capabilities. Optionally, the first timeline requirement includes: the processing timeline of UCI multiplexing carried on the CG uplink shared channel to the DG uplink shared channel, wherein the processing timeline can be defined as: the target time interval from the earliest start symbol of the CG uplink shared channel and the DG uplink shared channel to the last symbol of the first downlink channel. Accordingly, meeting the first timeline requirement means that the time interval from the earliest start symbol of the CG uplink shared channel and the DG uplink shared channel to the last symbol of the first downlink channel is greater than the target time interval.

[0189] Optionally, in step F-1, the terminal transmits at least one of the uplink control information on the first target resource and the dynamically authorized uplink shared channel, based on the satisfaction of the first timeline requirement when multiplexing the uplink control information on the first target resource to the second target resource, including at least one of the following G-1 to G-4:

[0190] G-1: When the first resource and the second resource are allowed to overlap in the time domain, and the uplink control information on the first resource is multiplexed onto the second resource to meet the first timeline requirements, the terminal sends the uplink control information on the first resource through the second resource, wherein the first resource includes a configuration-granted uplink shared channel resource carrying uplink control information in the first target resource, and the second resource includes a dynamically configured granted uplink shared channel resource in the second target resource;

[0191] For example, as shown in Figure 8, if the UE is scheduled by the network-side device to have a DG PUSCH that overlaps with the CG PUSCH, and the UCI is multiplexed onto the DG PUSCH to meet the first timeline requirement, the UCI that was originally multiplexed onto the CG PUSCH will be multiplexed onto the DG PUSCH (due to the single-carrier characteristic of uplink transmission). That is, the UCI that is transmitted on the CG PUSCH is carried on the DG PUSCH for transmission.

[0192] G-2: When the first resource and the second resource are allowed to overlap in the time domain, and the uplink control information of the first resource is reused on the second resource without meeting the first timeline requirements, the terminal transmits the high-priority channel in the channel corresponding to the first resource and the second resource according to the fourth configuration information, and discards the low-priority channel. The fourth configuration information is used to indicate the priority of the configured authorized uplink sharing channel and the dynamically authorized uplink sharing channel.

[0193] For example, as shown in Figure 9, if a UE is scheduled by the network-side device to have a DG PUSCH that overlaps with a CG PUSCH, and the UCI multiplexing to the DG PUSCH meets the first timeline requirement, the network-side device can configure the transmission priority of the DG PUSCH and the UCI, i.e., transmit the high-priority channel and discard the low-priority channel; optionally, in this case, the UE considers it an error; that is, the UE does not allow the network to schedule it in this way; or the UE considers it an error if the DG PUSCH and the CG PUSCH carrying the UCI have the same priority; that is, the UE does not allow the network to schedule it in this way.

[0194] G-3: When the third resource and the second resource are allowed to overlap in the time domain, and the uplink control information reuse on at least one of the third resources does not meet the first timeline requirement on the second resource, the terminal transmits the high-priority channel in the channel corresponding to the third resource and the second resource according to the fourth configuration information, and discards the low-priority channel. The third resource includes multiple configuration-authorized uplink shared channel resources carrying uplink control information in the first target resource.

[0195] For example, as shown in Figure 10, if a UE is scheduled by the network-side device to have a DG PUSCH that overlaps with multiple CG PUSCHs carrying UCI, and if multiplexing of UCI on at least one CG PUSCH to the DG PUSCH does not meet the first timeline requirement, the network-side device can configure the transmission priority of the DG PUSCH and UCI, i.e., transmit the high-priority channel and discard the low-priority channel; optionally, in this case, the UE considers it an error; that is, the UE does not allow the network to schedule it in this way; or the UE considers that if the DG PUSCH and the CG PUSCH carrying UCI have the same priority, then it is an error; that is, the UE does not allow the network to schedule it in this way.

[0196] Item G-4: When the first resource and the fourth resource are allowed to overlap in the time domain, and the uplink control information on the first resource is reused on the fifth resource to meet the first timeline requirement, and the uplink control information on the first resource is reused on the sixth resource to not meet the first timeline requirement, the terminal transmits the uplink control information of the first resource through the fifth resource, or transmits the high-priority channel in the channels corresponding to the first resource and the fourth resource according to the fourth configuration information, and discards the low-priority channel. The fourth resource includes multiple dynamically licensed uplink shared channel resources in the second target resource, the fifth resource includes some resources in the fourth resource, and the sixth resource includes resources in the fourth resource other than the fifth resource.

[0197] For example, if a CG PUSCH carrying UCI overlaps with multiple DG PUSCHs, and the UCI on the CG PUSCH is multiplexed onto some DG PUSCHs to meet the first timeline requirement, but the UCI on the CG PUSCH is multiplexed onto some DG PUSCHs to not meet the first timeline requirement, then one of the following can be performed:

[0198] UE multiplexes UCI onto the earliest DG PUSCH that meets the first timeline requirements;

[0199] The UE considers this an error; or the UE considers it an error if the DG PUSCH and the CG PUSCH carrying the UCI have the same priority; that is, the UE does not allow the network to schedule them in this way.

[0200] Network-side devices are configured with transmission priorities for DG PUSCH and UCI, meaning that high-priority channels are transmitted and low-priority channels are discarded.

[0201] As can be seen from the above, the embodiments of this application also provide a method for transmitting UCI when the CG uplink shared channel resources and DG uplink shared channel resources carrying UCI overlap in the time domain, so that the UCI transmission method of the embodiments of this application can be applied to more scenarios.

[0202] Understandably, network-side devices can be configured to allow time-domain overlap between a DG uplink shared channel and a CG uplink shared channel carrying UCI on the same carrier.

[0203] As can be seen from the above, when the resources of the CG uplink shared channel carrying UCI (i.e., the first target resource mentioned above) and the resources of the DG uplink shared channel (i.e., the second target resource) overlap in the time domain, some UCI may be dropped. The following describes in detail how to retransmit when there are dropped UCI.

[0204] Optionally, the method further includes:

[0205] The terminal receives a second instruction information from the network-side device;

[0206] The terminal resends the first object according to the second instruction information;

[0207] The second indication information is used to indicate at least one of the following:

[0208] Retransmit the discarded uplink control information;

[0209] Uplink control information from at least one Hybrid Automatic Repeat Request (HARQ) process;

[0210] At least one uplink control message;

[0211] Uplink control information for at least one carrier;

[0212] The first object includes:

[0213] Discarded uplink control information;

[0214] The second indication information indicates uplink control information for at least one HARQ process;

[0215] The second indication information indicates at least one uplink control message;

[0216] The second indication information indicates uplink control information for at least one carrier.

[0217] For example, when the second indication information indicates that the discarded uplink control information should be retransmitted, the first object includes the discarded uplink control information;

[0218] When the second indication information indicates the uplink control information of at least one HARQ process, the first object includes the uplink control information of at least one HARQ process indicated by the second indication information.

[0219] When the second indication information indicates at least one uplink control information, the first object includes at least one uplink control information indicated by the second indication information;

[0220] When the second indication information indicates uplink control information for at least one carrier, the first object includes the uplink control information for at least one carrier indicated by the second indication information.

[0221] Therefore, in the embodiments of this application, a dynamic scheduling-based discarded UCI re-triggering mechanism is also provided, which enables the discarded UCI to be retransmitted in the PUSCH, avoiding data rescheduling and improving resource utilization efficiency.

[0222] If there is a discarded UCI, the terminal may retransmit only the discarded UCI, or it may retransmit at least one UCI indicated by the network-side device through the second indication information.

[0223] Optionally, if the first object includes discarded uplink control information, the terminal retransmits the first object, including:

[0224] The terminal receives retransmission indication information, wherein the retransmission indication information is used to indicate retransmission time information;

[0225] The terminal retransmits the discarded uplink control information according to the retransmission instruction information.

[0226] Therefore, for a discarded UCI, the network-side device can trigger a discarded UCI retransmission DCI, instructing the UE to transmit the UCI using (CG)PUSCH.

[0227] Optionally, the retransmission indication information includes at least one of the following:

[0228] The second interval is used to indicate the interval between the time unit where the retransmission indication information is located and the first time unit, where the first time unit is the time unit where the discarded uplink control information is located.

[0229] The third interval is used to indicate the interval between the time unit where the retransmission indication information is located and the second time unit, where the second time unit is the time unit for retransmitting the discarded uplink control information.

[0230] If the second interval is represented by OffsetA and the third interval by OffsetB, then the second and third intervals can be represented as shown in Figure 11.

[0231] Optionally, the terminal retransmits the discarded uplink control information, including at least one of the following J-1 to J-3:

[0232] J-1: The terminal sends the discarded uplink control information through available resources after the seventh resource;

[0233] For example, when UCI is carried on PUSCH as MAC CE signaling, the PUSCH carrying UCI is discarded. The discarded UCI can be transmitted by delaying it to the next PUSCH. This achieves UCI retransmission without the need for complex prioritization (discarding), which can save the overhead of scheduling retransmission and improve resource utilization.

[0234] J-2: The terminal sends discarded uplink control information through a resource with the same configuration information (i.e., configuration parameters) as the seventh resource; the configuration information may be, for example, an index, that is, the terminal can send discarded uplink control information through a resource with the same index as the fourth resource;

[0235] J-3: The terminal transmits discarded uplink control information through the resources of the most recently scheduled uplink shared channel;

[0236] The seventh resource includes the resources of the configuration-authorized uplink shared channel carrying discarded uplink control information.

[0237] Optionally, the configuration authorization uplink shared channel corresponding to the first target resource carries a media access control and control unit (MAC CE), and the MAC CE includes the uplink control information.

[0238] Therefore, when transmitting UCI through the CG uplink shared channel, UCI (such as at least one of HARQ and CSI) can be carried as MAC CE signaling on the CG uplink shared channel.

[0239] Optionally, the header information of the MAC CE includes at least one of the following H-1 to H-4:

[0240] H-1 item: Carrier index of uplink control information that needs to be fed back;

[0241] H-2: Number of carriers for which uplink control information needs to be fed back;

[0242] H-3: The type of uplink control information that needs to be fed back;

[0243] H-4: The number of time units that need to provide feedback on uplink control information; wherein, when the uplink control information that needs to be provided feedback includes feedback information of the first downlink channel, the time unit refers to the time unit occupied by the first downlink channel, such as the first downlink channel transmitted in each of multiple time slots.

[0244] Therefore, when UCI is carried as MAC CE signaling on the CG uplink shared channel, the header information of MAC CE may include at least one of H-1 to H-4 mentioned above, so that the network-side device can obtain the indication information of the UCI specifically transmitted by the terminal.

[0245] Secondly, UCI is transmitted via the uplink control channel:

[0246] Optionally, the resources of the uplink control channel satisfy at least one of the following K-1 to K-2:

[0247] K-1: After the uplink control channel resource is updated by the network-side device for the terminal, the resource start symbol of the uplink control channel does not change;

[0248] For example, as shown in Figure 12, when DL DCI2 schedules PUCCH2, the resource start symbol of PUCCH2 changes relative to the resource start symbol of PUCCH1. Similarly, as shown in Figure 13, when PUCCH1 scheduled by DL DCI1 overlaps with CSI, PUCCH1 and CSI may reuse new PUCCH resources, i.e., the resources of PUCCH2, and the resource start symbol of this PUCCH changes relative to the resource start symbol of PUCCH1. In other words, the situations shown in Figures 12 and 13 are forms that the UE does not expect.

[0249] For example, as shown in Figure 14, when DL DCI2 schedules PUCCH2, the resource start symbol of PUCCH2 remains unchanged relative to the resource start symbol of PUCCH1. For example, as shown in Figure 15, when PUCCH1 scheduled by DL DCI1 overlaps with CSI, PUCCH1 and CSI multiplex the resources of PUCCH2, and the resource start symbol of this PUCCH remains unchanged relative to the resource start symbol of PUCCH1. That is, the situations shown in Figures 14 and 15 are the forms expected by the UE.

[0250] K-2: After the uplink control channel resource is updated by the network-side device for the terminal, the resource length of the uplink control channel does not change;

[0251] Therefore, when the uplink control channel is enabled, transmitting UCI through the uplink control channel requires satisfying at least one of the above K-1 to K-2 conditions.

[0252] It is understandable that if the resources used to carry the uplink control channel for UCI satisfy at least one of K-1 to K-2 above, then no resource movement will occur when the multiplexing described above occurs. This can reduce the multiplexing process of transmitting UCI through the uplink control channel, thereby simplifying the complexity of network and UE implementation and reducing power consumption.

[0253] Optionally, if the uplink control information includes feedback information from the first downlink channel, in step 202 above, the terminal sends the uplink control information through the uplink control channel, including the following steps L-1 to L-2:

[0254] Step L-1: The terminal determines whether the DCI currently received for scheduling the first downlink channel is the last DCI in the DCIs associated with the same codebook construction, and obtains the determination result;

[0255] Step L-2: The terminal sends the uplink control information through the uplink control channel according to the judgment result.

[0256] Therefore, when the terminal receives the first downlink channel, it can determine whether the DCI is the last DCI associated with the same codebook construction when it receives the DCI sent by the network-side device to schedule the first downlink channel. Then, based on the determination result, it can further send the above control information through the uplink control channel.

[0257] Optionally, in step L-2, the terminal sends the uplink control information through the uplink control channel according to the judgment result, including:

[0258] If the DCI currently received by the terminal for scheduling the first downlink channel is not the last DCI associated with the same codebook construction, the terminal skips the multiplexing and cancellation operations. Wherein, if the resources of the feedback information corresponding to the currently received DCI overlap with the resources of other uplink information, the multiplexing operation is used to indicate the multiplexing process of the feedback information corresponding to the currently received DCI with the other uplink information, and the cancellation operation is used to indicate the cancellation of the channel where the feedback information corresponding to the currently received DCI is located with the channel with the lower priority among the channels where the other uplink information is located.

[0259] If the DCI currently received by the terminal for scheduling the first downlink channel is the last DCI in the DCIs associated with the same codebook construction, the terminal determines a third target resource for carrying the uplink control channel of the second object, and performs the multiplexing operation and the cancellation operation according to the third target resource, wherein the second object includes feedback information of the first downlink channel scheduled by the DCIs associated with the same codebook construction.

[0260] For example, in Figure 16, high-priority HP DCI1 and HP DCI2 are associated with the same codebook. In current related technologies, low-priority (LP) DCI schedules LP PUCCH; then, high-priority (HP) DCI1 schedules HP HARQ1. HARQ1 overlaps with SR, so a multiplexing operation is performed, i.e., HARQ1 and SR are multiplexed together, and HP intermediate PUCCH1 resource is selected. If HP intermediate PUCCH1 and LP PUCCH resources overlap, a cancellation operation is performed, i.e., the transmission of LP PUCCH is cancelled. Subsequently, HP DCI2 schedules HARQ2. HP intermediate PUCCH1 and HARQ2 resources need to be multiplexed, i.e., HARQ1, SR, and HARQ2 are multiplexed to HP intermediate PUCCH2. That is, HARQ1, SR, and HARQ2 are transmitted through HP intermediate PUCCH2. However, HP intermediate PUCCH2 does not overlap with the cancelled LP PUCCH, thus creating the problem that LP PUCCH can be cancelled even without cancellation.

[0261] In this embodiment of the application, for DCI1, the above-mentioned intermediate multiplexing and cancellation operations are not performed. Only when the terminal receives DCI2 (i.e., the last DCI in the codebook construction) will the resources carrying HARQ1 corresponding to DCI1 and HARQ2 corresponding to DCI2 be determined, and it will be determined whether there is overlap with the resources of other uplink information. Then, the corresponding multiplexing and cancellation operations will be performed. In this way, LP PUCCH will not be cancelled.

[0262] Therefore, in this embodiment, for multiple DCIs associated with the same codebook, the intermediate multiplexing and cancellation operations described above are not performed for each DCI before the last DCI. After the terminal receives the last DCI, it determines the third target resource used to carry the feedback information corresponding to the multiple DCIs associated with the same codebook. Then, based on whether the third target resource overlaps with other uplink information resources, the corresponding multiplexing and cancellation operations are performed, thereby avoiding the problem of unnecessary cancellation of low-priority channels.

[0263] Optionally, the terminal determines whether the currently received DCI for scheduling the first downlink channel is the last DCI associated with the same codebook construction, including one of the following P-1 to P-2:

[0264] Item P-1: The time and reference time information of the DCI currently received by the terminal for scheduling the first downlink channel are used to determine whether the currently received DCI for scheduling the first downlink channel is the last DCI in the DCI associated with the same codebook construction.

[0265] The reference time information includes a reference time point and a reference timeline. The reference timeline represents a time interval prior to the reference time point, i.e., the reference timeline refers to a time interval. The reference timeline and the reference time point can be configured by the network-side device or predefined.

[0266] Furthermore, if the terminal receives a DCI at the target time point, then that DCI is the last DCI associated with the same codebook construction; if the terminal does not receive a DCI at the target time point, then the most recently received DCI before the target time point is the last DCI associated with the same codebook construction; wherein, the target time point is located before the reference time point, and the interval between the target time point and the reference time point is the interval represented by the reference time line.

[0267] Therefore, in this embodiment of the application, the network-side device can configure the aforementioned reference timeline and reference time point for the terminal. In this way, the terminal can determine whether a DCI constructed in association with the same codebook is the last DCI based on the distance between the time of the received DCI and the aforementioned target time point.

[0268] Furthermore, when a terminal receives a DCI, it determines, based on the reference timeline information, whether the DCI is the last DCI associated with the same codebook construction. This determines whether multiplexing and cancellation operations need to be performed. That is, it is not necessary to perform multiplexing and cancellation operations on the resources indicated by each DCI received. Instead, it is only necessary to perform multiplexing and cancellation operations on the uplink control information associated with the same codebook construction when receiving the last DCI. Therefore, in this embodiment, a simpler reference timeline can be configured for performing multiplexing and cancellation operations, thereby simplifying the multiplexing and cancellation process of transmitting UCI through the uplink control channel.

[0269] Optionally, the reference time information is used to indicate at least one of the following V-1 to V-2:

[0270] V-1 item: The multiplexing timeline used to perform the multiplexing operation is the same as the cancellation timeline used to perform the cancellation operation;

[0271] V-2: At least one of the N1, N2, and N3 values ​​is the same; the same value may be a reference value indicated by the network-side device;

[0272] Wherein, when the resources of the first feedback information overlap with the resources of other uplink information, the multiplexing operation refers to the process of multiplexing the first feedback information with the other uplink information, and the cancellation operation refers to canceling the channel where the first feedback information is located and the channel where the other uplink information is located, which has a lower priority. The first feedback information includes feedback information of a first downlink channel scheduled by DCI.

[0273] The N1 value represents the time from the first downlink channel to the feedback information of the first downlink channel;

[0274] The N2 value represents the time it takes for the DCI of the uplink shared channel to be scheduled to the uplink shared channel;

[0275] The N3 value represents the time from the second DCI that schedules the first downlink channel to the uplink control channel (carrying the corresponding feedback information) indicated by the first DCI that schedules the first downlink channel.

[0276] It is understood that the reference time information, including the reference time point and the reference timeline, can determine a target time point as described above. Thus, the reference time information can indicate at least one of V-1 to V-2 mentioned above.

[0277] Optionally, the reference time point is the starting symbol of a low-priority channel; for example, the cancellation timeline used to perform the cancellation operation is y symbols before the starting symbol of the low-priority channel.

[0278] It should be noted that the timeline mentioned in this article refers to time intervals.

[0279] Item P-2: The terminal determines, based on the value of the first information field in the DCI that is currently being received for scheduling the first downlink channel, whether the DCI that is currently being received for scheduling the first downlink channel is the last DCI in the DCI that is associated with the same codebook construction.

[0280] Optionally, the first information field includes at least one of the following T-1 to T-2:

[0281] T-1: The information field containing the K1 value; where K1 is used to indicate the time unit of the uplink control channel carrying the feedback information of the first downlink channel for DCI scheduling; for example, if the K1 value in the currently received DCI is not a numeric value, it means that the currently received DCI is not the last DCI in the DCIs associated with the same codebook construction; if the K1 value in the currently received DCI is a numeric value, it means that the currently received DCI is the last DCI in the DCIs associated with the same codebook construction.

[0282] T-2: Information fields added to the DCI; for example, for information fields added to various DCIs associated with the same codebook, the value of the information field added in the last DCI is a first preset value, and the value of the information field added in other DCIs is a second preset value; for example, the first preset value is 1 and the second preset value is 0; or, for example, the values ​​of the information fields added to various DCIs associated with the same codebook are the same; for example, the values ​​of the newly added information fields in the multiple DCIs received by the UE are 0 or 1, DCIs with all values ​​of 0 are associated with the same codebook, and DCIs with all values ​​of 1 are associated with another codebook.

[0283] Furthermore, to facilitate understanding of the above content regarding determining whether a DCI is the last DCI in the same codebook construction, the following example is provided:

[0284] First example: For DCIs associated with a codebook construction (i.e., a codebook construction on a time-domain unit), only the K1 indicator in the last DCI indicates the actual value, while the K1 in other DCIs indicates a non-numeric value (NNK), as shown in Figure 17. In this case, after receiving each DCI, the UE determines whether it is the final DCI (i.e., the last DCI associated with the same codebook construction) by judging whether the K1 in the DCI is a numeric value; and the UE does not perform uplink control information multiplexing or cancellation operations between different priorities before receiving the last DCI.

[0285] It should be noted that the UE does not expect confusion between different HARQ codebooks. For example, the HARQ-ACK feedback of the PDSCH in slot q should be on the PUCCH / PUSCH of slot n; if the PDCCH with C-DAI=3 is lost, the HARQ-ACK feedback of the PDSCH in slot q should not affect the codebook construction of slot m.

[0286] In the second example, the UE receives network configuration information and adds an F (Final)-DCI indicator field to the DCI, for example, consisting of 1 bit. This indicator field indicates whether a DL scheduling DCI is the last DCI in the codebook construction, as shown in Figure 18. In this case, after receiving each DCI, the UE determines whether the currently received DCI is the final DCI (i.e., the last DCI associated with the same codebook construction) by the value of the F-DCI field in the DCI. Furthermore, the UE does not perform uplink control information multiplexing or cancellation operations between different priorities before receiving the last DCI.

[0287] It should be noted that the UE does not expect confusion between different HARQ codebooks. For example, the HARQ-ACK feedback for the PDSCH in slot q should be on the PUCCH / PUSCH in slot n. If the PDCCH with C-DAI=3 is lost, the HARQ-ACK feedback for the PDSCH in slot q should not affect the codebook construction in slot m.

[0288] Third example: For a DCI associated with a codebook construction, K1 indicates the actual value only in the last DCI, and K1 in other DCIs will be indicated as a non-numeric value (NNK); and the UE can receive configuration information from the network-side device to add an indicator field (CI) belonging to the same codebook in a time domain unit to the DCI (e.g., composed of 1 bit), as shown in Figure 19, in the DCI of the PDSCH scheduling associated with the codebook of slot m, CI is set to 0, and in the DCI of the PDSCH scheduling associated with the codebook of the next slot, slot n, CI is set to 1, and so on in the order of 0, 1, 0, 1.

[0289] In this case, after receiving each DCI, the UE determines whether it is the final DCI (i.e., the last DCI associated with the same codebook construction) by judging whether K1 in the DCI is a digital value, or by judging whether the value of the added indication field CI is the same as that of the previous DCI. Furthermore, the UE does not perform uplink control information multiplexing or cancellation operations between different priorities before receiving the last DCI.

[0290] Thirdly, UCI is transmitted through the uplink control channel and the uplink shared channel:

[0291] Optionally, in step 202 above, the terminal transmits the uplink control information through at least one of the uplink shared channel and the uplink control channel, including:

[0292] The terminal selects at least one of the uplink control channel and the uplink shared channel to send the uplink control information according to the target parameters of the uplink control information;

[0293] The target parameter includes at least one of the following:

[0294] The type of the uplink control information;

[0295] The priority of the uplink control information;

[0296] The payload of the uplink control information.

[0297] Therefore, it can be seen that UCI can be transmitted through at least one of the uplink control channel and uplink shared channel, depending on at least one of the UCI type, priority, and payload.

[0298] Among them, UCI may include feedback information of the first downlink channel (e.g., HARQ-ACK of PDSCH), at least one of CS; CSI includes RI, PMI, CQI, CLI information, and at least one of the sensing results;

[0299] For example, UCI can be classified into type-A / B. Type A can report HARQ-ACK, etc., while type B can report information including RI, PMI, CQI, CLI, perception results, etc. Type A can be carried on PUCCH, while type B can be carried on PUCCH or PUSCH (depending on the configuration).

[0300] Alternatively, UCIs can be categorized by priority. For example, PUCCH carries high-priority UCIs, and PUSCH carries low-priority UCIs, such as CSIs. That is, if a high-priority feedback exists, the PUCCH directly carries the high-priority UCI, while the low-priority CSI is carried via the PUSCH. It's important to note that the priority here refers to the priority of UCI types within the same service, not the priority of different services. For different services, the service priority takes precedence. For example, a high-priority CSI can cancel a low-priority HARQ-ACK, even if the HARQ-ACK priority is higher than the CSI priority within the same service's UCI.

[0301] Alternatively, for example, the network-side device can be configured to allow the UE to determine whether to use PUCCH or PUSCH to carry the UCI based on the payload. For instance, it can be determined based on the number of bits: bits less than Z are transmitted via PUCCH, while bits greater than Z (or all or more than X remaining bits) are transmitted via PUSCH.

[0302] Optionally, the method further includes:

[0303] The terminal sends a third indication message, wherein the third indication message is used to indicate the channel through which the uplink control information is transmitted.

[0304] Therefore, the terminal can suggest UCI transmission methods to the network-side device, such as whether to enable PUCCH, thereby helping the network-side device to configure UCI transmission according to the terminal's suggestions.

[0305] Optionally, the third indication information includes at least one of the following:

[0306] Indication information used to indicate the transmission of uplink control information through the uplink control channel; for example, when PUCCH and PUSCH overlap, UCI will be multiplexed onto PUSCH;

[0307] Indication information used to indicate the transmission of uplink control information through the uplink shared channel;

[0308] The format of the uplink shared channel includes at least one of the first format and the second format described above.

[0309] Optionally, the third indication information is carried on the uplink control channel or the uplink shared channel.

[0310] Therefore, the third indication information, which is a suggestion message, can be carried on the uplink shared channel or the uplink control channel, for example, as a UCI type.

[0311] Referring to Figure 20, an embodiment of this application also provides an uplink control information transmission method, which may include the following steps 2001 or 2002:

[0312] Step 2001: With the uplink control channel closed, the network-side device receives uplink control information through the uplink shared channel;

[0313] Step 2002: When the uplink control channel is enabled, the network-side device receives the uplink control information through at least one of the uplink shared channel and the uplink control channel.

[0314] As shown in steps 2001 and 2002, in this embodiment, when the uplink control channel is closed, the network-side device receives uplink control information through the uplink shared channel; when the uplink control channel is open, the network-side device receives uplink control information through at least one of the uplink shared channel and the uplink control channel. Therefore, in this embodiment, the uplink control channel can be opened or closed. When the uplink control channel is closed, uplink control information is transmitted through the uplink shared channel; when the uplink control channel is open, uplink control information is transmitted through at least one of the uplink shared channel and the uplink control channel. Thus, in this embodiment, the uplink control channel can be flexibly opened or closed under different situations or scenarios, thereby meeting different transmission requirements of uplink control information and achieving more flexible uplink control information transmission.

[0315] Optionally, the method further includes one of the following A2-1 to A2-2:

[0316] Item A2-1: When the terminal receives the first configuration information and the first configuration information indicates that the uplink control channel should be turned off, the terminal turns off the uplink control channel;

[0317] Item A2-2: When the terminal receives the first configuration information and the first configuration information indicates that the uplink control channel should be enabled, or when the terminal is not configured with the first configuration information, the terminal enables the uplink control channel.

[0318] It is understandable that the relevant explanations for items A2-1 and A2-2 here can be found in the explanations for items A1-1 and A1-2 above, and will not be repeated here.

[0319] As shown in steps 2201 to 2202, network-side devices can receive UCIs through the uplink shared channel, the uplink control channel, or both. The following sections will describe the relevant aspects of UCI transmission from these three perspectives.

[0320] First aspect: Transmitting UCI via the uplink shared channel:

[0321] Optionally, in step 2002 above, the network-side device receives the uplink control information through the uplink shared channel, including:

[0322] The network-side device sends second configuration information to the terminal, wherein the second configuration information is used to configure a configuration-authorized uplink shared channel for transmitting the uplink control information;

[0323] When the first target resource and the second target resource do not overlap in the time domain, the network-side device receives the uplink control information sent by the terminal through the first target resource, wherein the first target resource includes a configuration-granted uplink shared channel resource for carrying the uplink control information determined according to the second configuration information, and the second target resource includes resources for a dynamically granted uplink shared channel.

[0324] Therefore, it can be seen that network-side devices can configure a Configured Grant (CG) uplink shared channel for the terminal to transmit uplink control information, so that when the uplink control channel is turned off, the terminal can transmit UCI through the CG uplink shared channel.

[0325] The following is a detailed description of the contents included in the second configuration information, as described in both semi-static and dynamic configuration sections:

[0326] I. Semi-static configuration:

[0327] Optionally, the second configuration information includes at least one of the following C-1 to C-2:

[0328] C-1: First indication information, used to indicate the format of the configured authorized uplink shared channel, wherein the format of the configured authorized uplink shared channel includes a first format and a second format, the first format is used to indicate that the configured authorized uplink shared channel transmits the uplink control information but does not transmit data, and the second format is used to indicate that the configured authorized uplink shared channel can transmit the uplink control information and data simultaneously;

[0329] C-2: Codebook type indicator, used to indicate the codebook type of UCI carried on the CG uplink shared channel.

[0330] Optionally, the second configuration information may further include at least one of the following items C-3 to C-13 of the CG uplink shared channel:

[0331] C-3: Time Domain Offset;

[0332] C-4: Time Domain Allocation;

[0333] Item C-5: Frequency Domain Allocation;

[0334] Item C-6: Antenna Port;

[0335] Item C-7: Demodulation Reference Signal (DMRS) sequence initialization (dmrs-SeqInitialization);

[0336] C-8 item: precoding and number of layers;

[0337] Item C-9: Sounding Reference Signal (SRS) Resource Indicator;

[0338] Item C-10: Modulation and coding strategy and transport block size (mcsAndTBS);

[0339] Item C-11: Frequency Hopping Offset;

[0340] Item C-12: Path Loss Reference Index;

[0341] Item C-13: Physical layer priority index (phy-PriorityIndex).

[0342] The relevant explanations for items C-1 to C-13 here can be found in the previous text and will not be repeated here.

[0343] II. Dynamic Configuration

[0344] Optionally, the second configuration information further includes at least one of the following D-1 to D-4:

[0345] Item D-1: Transmission parameters for the configuration-authorized uplink shared channel used to transmit the uplink control information;

[0346] Item D-2: The type of uplink control information carried on the configuration authorization uplink shared channel for transmitting the uplink control information;

[0347] D-3: First interval, wherein, when the uplink control information includes feedback information of the first downlink channel, the first interval is used to indicate a time unit of interval between the first downlink channel and the configured authorized uplink shared channel;

[0348] Item D-4: Index of the configuration-authorized uplink shared channel used to transmit the uplink control information.

[0349] The relevant explanations for items D-1 to D-4 here can be found in the previous text and will not be repeated here.

[0350] Optionally, the index of the configuration-granted uplink shared channel used to transmit the uplink control information corresponds to at least one of the following:

[0351] The format of the configuration-authorized uplink shared channel used to transmit the uplink control information may include the first format and the second format described above.

[0352] The start symbol of the configuration-authorized uplink shared channel used for transmitting the uplink control information;

[0353] The number of continuous symbols for the configuration-authorized uplink shared channel used to transmit the uplink control information.

[0354] Therefore, the index of each CG uplink shared channel can be associated with at least one of the following: the format, start symbol, and number of continuous symbols of the CG uplink shared channel.

[0355] Optionally, if the uplink control information includes feedback information of the first downlink channel, the second configuration information is carried on the downlink control information (DCI) that schedules the first downlink channel.

[0356] Optionally, the method further includes:

[0357] The network-side device receives the terminal's data scheduling request by configuring an authorized uplink shared channel.

[0358] It should be noted that the configuration method of the CG uplink shared channel used to carry the terminal's scheduling request (SR) can be the same as the configuration method of the CG uplink shared channel used to carry UCI described above.

[0359] Optionally, the network-side device receives uplink control information through the uplink shared channel, including:

[0360] The network-side device sends third configuration information, wherein the third configuration information is used to indicate the codebook type;

[0361] The network-side device determines the target codebook for uplink control information carried on the Dynamic Authorization Uplink Shared Channel based on the third configuration information.

[0362] The network-side device receives the uplink control information through the dynamic authorization uplink shared channel according to the target codebook.

[0363] Therefore, the network-side equipment can also configure third configuration information for the terminal to indicate the codebook type, so that the terminal can determine the target codebook of UCI carried on the DG uplink shared channel according to the codebook type indicated by the third configuration information, and then send UCI through the DG uplink shared channel according to the target codebook; correspondingly, the network-side equipment can determine the target codebook according to the third configuration information, and then receive UCI through the DG uplink shared channel according to the target codebook.

[0364] In the case where the second information field indicating the codebook type in the third configuration information is empty, the codebook type carried on the dynamically scheduled uplink shared channel is the same as the codebook type to be carried on the overlapping configuration-granted uplink shared channel; that is, if the DG uplink shared channel overlaps with the CG uplink shared channel carrying UCI, the UCI on the CG uplink shared channel will be carried on the DG uplink shared channel. Here, the empty value indicates that the codebook type is the same as the type of the overlapping CG uplink shared channel.

[0365] When the uplink control information includes feedback information of the first downlink channel and the second information field is codebook type one (i.e., semi-static HARQ codebook), the codebook type carried on the dynamically scheduled uplink shared channel is type 1 HARQ-ACK codebook (i.e., Type-1 HARQ-ACK codebook).

[0366] When the uplink control information includes feedback information of the first downlink channel and the first information field is codebook type 2 (i.e., dynamic HARQ codebook), the codebook type carried on the dynamically scheduled uplink shared channel is type 2 HARQ-ACK codebook (i.e., Type-2 HARQ-ACK codebook).

[0367] When the uplink control information includes feedback information of the first downlink channel, and the first information field is codebook type three (i.e., codebook that feeds back HARQ according to the configured number of carriers or processes), the codebook type carried on the dynamically scheduled uplink shared channel is type 3 HARQ-ACK codebook (i.e., Type-3 HARQ-ACK codebook).

[0368] Optionally, the third configuration information is carried on the DCI that schedules the dynamically authorized uplink shared channel.

[0369] Furthermore, as described above regarding the uplink control information transmission method applied to the terminal, when the resources of the CG uplink shared channel carrying UCI (i.e., the aforementioned first target resource) and the resources of the DG uplink shared channel (i.e., the second target resource) overlap in the time domain, some uplink control information may be discarded. The following section details how to retransmit discarded UCI.

[0370] Optionally, the method further includes:

[0371] The network-side device sends a second instruction message to the terminal;

[0372] The network-side device receives the first object retransmitted by the terminal according to the second instruction information;

[0373] The second indication information is used to indicate at least one of the following:

[0374] Retransmit the discarded uplink control information;

[0375] Uplink control information from at least one Hybrid Automatic Repeat Request (HARQ) process;

[0376] At least one uplink control message;

[0377] Uplink control information for at least one carrier;

[0378] The first object includes:

[0379] Discarded uplink control information;

[0380] The second indication information indicates uplink control information for at least one HARQ process;

[0381] The second indication information indicates at least one uplink control message;

[0382] The second indication information indicates uplink control information for at least one carrier.

[0383] Therefore, in the embodiments of this application, a dynamic scheduling-based discarded UCI re-triggering mechanism is also provided, which enables the discarded UCI to be retransmitted in the PUSCH, avoiding data rescheduling and improving resource utilization efficiency.

[0384] If there is a discarded UCI, the terminal may retransmit only the discarded UCI, or it may retransmit at least one UCI indicated by the network-side device through the second indication information.

[0385] Optionally, if the first object includes discarded uplink control information, the network-side device receiving the first object retransmitted by the terminal according to the second indication information includes:

[0386] The network-side device sends a retransmission instruction to the terminal;

[0387] The network-side device receives the discarded uplink control information retransmitted by the terminal according to the retransmission instruction information.

[0388] Therefore, for a discarded UCI, the network-side device can trigger a discarded UCI retransmission DCI, instructing the UE to transmit the UCI using (CG)PUSCH.

[0389] Optionally, the retransmission indication information includes at least one of the following:

[0390] The second interval is used to indicate the interval between the time unit where the retransmission indication information is located and the first time unit, where the first time unit is the time unit where the discarded uplink control information is located.

[0391] The third interval is used to indicate the interval between the time unit where the retransmission indication information is located and the second time unit, where the second time unit is the time unit for retransmitting the discarded uplink control information.

[0392] For details regarding the second and third intervals, please refer to the previous text; they will not be repeated here.

[0393] Optionally, the configuration authorization uplink shared channel corresponding to the first target resource carries a media access control and control unit (MAC CE), and the MAC CE includes the uplink control information.

[0394] Therefore, when transmitting UCI through the CG uplink shared channel, UCI can be carried as MAC CE signaling on the CG uplink shared channel.

[0395] Optionally, the header information of the MAC CE includes at least one of the following H-1 to H-4:

[0396] H-1 item: Carrier index of uplink control information that needs to be fed back;

[0397] H-2: Number of carriers for which uplink control information needs to be fed back;

[0398] H-3: The type of uplink control information that needs to be fed back;

[0399] H-4: The number of time units that require feedback of uplink control information.

[0400] For details regarding items H-1 to H-4, please refer to the previous text; they will not be repeated here.

[0401] Alternatively, the method may further include:

[0402] The network-side device sends a fifth configuration information, wherein the fifth configuration information is used to indicate whether dynamic authorization uplink shared channel and configuration authorization uplink shared channel carrying uplink control information are allowed to overlap in the time domain on the same carrier.

[0403] Therefore, network-side equipment can be configured to allow time-domain overlap between a DG uplink shared channel and a CG uplink shared channel carrying UCI on the same carrier.

[0404] Secondly, UCI is transmitted via the uplink control channel:

[0405] Optionally, the resources of the uplink control channel satisfy at least one of the following K-1 to K-2:

[0406] K-1: After the uplink control channel resource is updated by the network-side device for the terminal, the resource start symbol of the uplink control channel does not change;

[0407] K-2: After the uplink control channel resource is updated by the network-side device for the terminal, the resource length of the uplink control channel does not change.

[0408] For details regarding items K-1 to K-2, please refer to the previous text; they will not be repeated here.

[0409] Optionally, the method further includes one of the following:
