Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, specifically to a transmission method, terminal, and base station for a Physical Uplink Control Channel (PUCCH). Background Technology

[0002] In a current physical uplink control channel (PUCCH) resource configuration method, the following functions are supported:

[0003] 1) Supports the simultaneous construction of two sets of hybrid automatic repeat request acknowledgment (HARQ-ACK) codebooks for the same terminal to meet the latency and reliability requirements of enhanced mobile broadband (eMBB) and ultra-reliable and low-latency communications (URLLC). The two sets of HARQ-ACK codebooks can correspond to two sets of PUCCH configuration parameters, i.e., two PUCCH-Configs.

[0004] 2) Each PUCCH-Config includes multiple PUCCH resource sets, and different PUCCH resource sets correspond to different uplink control information (UCI) payload sizes.

[0005] 3) Each PUCCH resource set contains 8 / 32 PUCCH resources. The configuration information of each PUCCH resource includes the number of Physical Resource Blocks (PRBs), the number of symbols, the format, the maximum code rate, and other information.

[0006] One existing method for determining PUCCH resources is as follows:

[0007] 1) PUCCH resources can be used to transmit UCI, which includes Scheduling Request (SR), HARQ-ACK, and Channel State Information (CSI).

[0008] 2) PUCCH resources for transmitting UCI can be semi-statically configured, such as PUCCHs carrying SR, periodic CSI, and HARQ-ACK for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH). Alternatively, PUCCH resources for transmitting UCI can also be a semi-statically configured / pre-configured set, dynamically indicated by downlink control information (DCI), such as PUCCHs carrying HARQ-ACK for dynamic PDSCH.

[0009] 2a) For dynamically indicated PUCCH resources: The DCI that schedules PDSCH contains up to 3 bits of PUCCH Resource Indicator (PRI) information, which is used to select a PUCCH resource from a plurality of semi-statically configured / pre-configured PUCCH resources;

[0010] 2b) When the terminal receives the semi-static configuration and downlink control information, it first selects a corresponding PUCCH resource set according to the UCI payload size, and then selects a PUCCH resource from the selected PUCCH resource set according to the PRI.

[0011] One approach to handling overlapping PUCCH scheduling is to disregard PUCCH priorities and allow overlapping PUCCH scheduling. For example... Figure 2 As shown, the base station sends the first DCI (first DCI) schedule PDSCH 1 and its HARQ-ACK 1, and then the base station sends the next DCI (last DCI) schedule PDSCH 2 and its HARQ-ACK 2. Figure 2As shown, the resources of HARQ-ACK 1 and HARQ-ACK 2 overlap, meaning they overlap at least partially in the time domain. Therefore, when the multiplexing timeline is met, the terminal can multiplex HARQ-ACK 1 and HARQ-ACK 2 onto the same PUCCH for transmission. Another approach is to differentiate the priorities of PUCCH / HARQ-ACK; HARQ-ACKs of the same priority can be multiplexed for transmission.

[0012] For example, if multiplexing of eMBB HARQ-ACK and URLLC HARQ-ACK is supported, since the target block error rates (BLERs) of eMBB HARQ-ACK and URLLC HARQ-ACK are different, different code rates should be used for transmission. For instance, a lower code rate should be used to transmit URLLC HARQ-ACK to ensure its reliability, while a higher code rate should be used to transmit eMBB HARQ-ACK to improve its spectral efficiency. Currently, existing technologies typically only support multiplexing of UCIs with the same priority, and the transmission code rate of the multiplexed UCIs is also the same, making it impossible to use different code rates for transmission according to the needs of different services.

Furthermore, features described with reference to certain examples may be combined in other examples.

[0108] Please see Figure 1 , Figure 1 This diagram illustrates a block diagram of a wireless communication system applicable to an embodiment of the present invention. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a user terminal or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment of the present invention. Network device 12 can be a base station and / or a core network element. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, WLAN access point, or other access point, etc.). The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in the embodiments of the present invention, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0109] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0110] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. Base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0111] Communication links in a wireless communication system may include an uplink for carrying uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a downlink for carrying downlink (DL) transmissions (e.g., from network device 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.

[0112] As described in the background section, existing technologies typically only support the multiplexing of UCIs with the same priority, and the transmission rate of the multiplexed UCIs is also the same, making it impossible to use different code rates for transmission according to the needs of different services. To solve at least one of the above problems, embodiments of the present invention provide a PUCCH transmission method that can realize the multiplexing transmission of UCIs with different priority indices. Furthermore, different code rates can be used for transmission of UCIs with different priorities, which can improve system spectrum efficiency while ensuring different service requirements.

[0113] Figure 3 and Figure 4 Two scenarios where PUCCH overlap may occur are provided. Among them, Figure 3 The first UCI is scheduled first, followed by the second UCI. Figure 4 In the latter case, the second UCI is scheduled first, followed by the first UCI. In both scenarios, the first and second UCIs may overlap. In this paper, overlap refers to temporal overlap, meaning partial or complete overlap in the temporal domain. As a specific example, PDSCH1 can be an eMBB PDSCH, and PDSCH2 can be a URLLC PDSCH. Correspondingly, the first UCI can be an eMBB HARQ-ACK, and the second UCI can be a URLLC HARQ-ACK. The above examples are merely illustrative and not intended to limit the scope of this invention.

[0114] Please refer to Figure 5 The present invention provides a method for transmitting a physical uplink control channel, which, when applied to the terminal side, includes:

[0115] Step 51: The terminal determines or is about to transmit at least two overlapping PUCCHs, including a first PUCCH and a second PUCCH. The first PUCCH is a first priority index, carrying or corresponding to a first UCI; the second PUCCH is a second priority index, carrying or corresponding to a second UCI. Then, the terminal transmits the first UCI and the second UCI on a third PUCCH, with the first UCI and the second UCI using different code rates.

[0116] Through the above steps, embodiments of the present invention can transmit UCI originally carried on at least two PUCCHs (or corresponding to at least two PUCCHs) in one PUCCH. Furthermore, embodiments of the present invention can use different code rates to encode UCI originally carried on PUCCHs with different priority indices, thereby ensuring the needs of different services and improving the system spectrum efficiency.

[0117] Optionally, in this embodiment of the invention, when the terminal needs to transmit at least two overlapping PUCCHs, the UCI and the second UCI can be transmitted on the third PUCCH only when the third PUCCH meets a preset condition. The preset condition may be that the third PUCCH meets the delay requirement of the first UCI or the second UCI. For example, the end symbol of the third PUCCH is no later than X symbols after the end symbol of the first PUCCH, and / or, the end symbol of the third PUCCH is no later than Y symbols after the end symbol of the second PUCCH. Here, X and Y are preset integers.

[0118] In this embodiment of the invention, the terminal transmits the first UCI and the second UCI on the third PUCCH, which may specifically include: determining the third PUCCH according to the third DCI, wherein the third DCI is used to indicate the transmission of the third PUCCH.

[0119] In this embodiment of the invention, the third DCI may be a DCI indicating the transmission of the first PUCCH or the second PUCCH, wherein the first PUCCH and the second PUCCH overlap, and optionally, the first PUCCH and the second PUCCH are in the same time slot / sub-time slot. The third DCI is the last DCI received between the first DCI and the second DCI. Here, the first DCI is used to indicate the transmission of the first PUCCH, and the second DCI is used for the transmission of the second PUCCH.

[0120] The third DCI is a first DCI used to indicate the transmission of the first PUCCH, and the first DCI is the latest received DCI among the DCIs scheduling the at least two PUCCHs. The third DCI is a second DCI used to indicate the transmission of the second PUCCH, and the second DCI is the latest received DCI among the DCIs scheduling the at least two PUCCHs.

[0121] The third PUCCH is one of at least one PUCCH resource configured in the third PUCCH configuration (third PUCCH-Config). Specifically, the PUCCH resource is configured by PUCCH resource configuration information. More specifically, the third PUCCH configuration can be the PUCCH configuration corresponding to one of the at least two PUCCHs, or it can be a PUCCH configuration other than the at least two PUCCHs.

[0122] 1) The third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI.

[0123] In other words, the third PUCCH configuration is either the PUCCH configuration corresponding to the priority index of the first PUCCH, or the PUCCH configuration corresponding to the first UCI. It can be understood that the PUCCH configuration corresponding to the first UCI and the PUCCH configuration corresponding to the priority index of the first PUCCH are different descriptions of the same PUCCH configuration. Similarly, the same applies to the PUCCH configuration corresponding to the second UCI.

[0124] 2) The third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI.

[0125] In other words, the third PUCCH configuration is either the PUCCH configuration corresponding to the priority index of the second PUCCH, or the PUCCH configuration corresponding to the second UCI. It is understood that the PUCCH configuration corresponding to the second UCI and the PUCCH configuration corresponding to the priority index of the second PUCCH are different descriptions of the same PUCCH configuration.

[0126] 3) The third PUCCH configuration is the PUCCH configuration configured for transmitting the first UCI and the second UCI.

[0127] Here, an additional third PUCCH configuration is configured for transmitting the first UCI and the second UCI. Through this third PUCCH configuration, at least one PUCCH resource for transmitting the first UCI and the second UCI can be configured.

[0128] The following provides several ways to determine the bitrate of the first UCI and the second UCI.

[0129] In the following implementations 1 to 3, the PUCCH resource configuration information corresponding to the third PUCCH is configured with a maximum bit rate. The PUCCH resource configuration information corresponding to the first PUCCH is configured with at most one maximum bit rate. The PUCCH resource configuration information corresponding to the second PUCCH is configured with at most one maximum bit rate.

[0130] Implementation method 1:

[0131] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the second PUCCH.

[0132] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the first PUCCH, and determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH.

[0133] Implementation method 2:

[0134] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine the code rate of the second UCI based on the code rate of the first UCI.

[0135] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine the code rate of the first UCI based on the code rate of the second UCI.

[0136] Implementation method 3:

[0137] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH. If the PUCCH resource configuration information corresponding to the second PUCCH is configured with a maximum code rate, then the code rate of the second UCI is determined to be the maximum code rate configured by the PUCCH resource configuration information corresponding to the second PUCCH; otherwise, if the PUCCH resource configuration information corresponding to the second PUCCH is not configured with a maximum code rate, then the code rate of the second UCI is determined to be the code rate of the first UCI plus, minus, multiplied, or divided by a third adjustment factor.

[0138] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 51 above, when the terminal transmits the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH. If the PUCCH resource configuration information corresponding to the first PUCCH is configured with a maximum code rate, then the code rate of the first UCI is determined to be the maximum code rate configured by the PUCCH resource configuration information corresponding to the first PUCCH; otherwise, the code rate of the first UCI is determined to be the code rate of the second UCI plus, minus, multiplied, or divided by a fourth adjustment factor.

[0139] In implementations 2 and 3 above, the bitrate of the second UCI is determined based on the bitrate of the first UCI. Specifically, the bitrate of the second UCI can be determined by adding, subtracting, multiplying, or dividing the bitrate of the first UCI by a first adjustment factor. Similarly, the bitrate of the first UCI can be determined based on the bitrate of the second UCI by adding, subtracting, multiplying, or dividing the bitrate of the second UCI by a second adjustment factor.

[0140] The first adjustment factor can be determined in one of the following ways:

[0141] A) The network (such as a base station) is configured or predefined through higher-layer signaling, such as through relevant protocols.

[0142] B) Determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or predefined, such as in a protocol.

[0143] Similarly, the second adjustment factor can also be determined in one of the following ways:

[0144] A) The network (such as a base station) is configured or predefined through higher-layer signaling, such as through relevant protocols.

[0145] B) Determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or predefined, such as in a protocol.

[0146] The first adjustment factor and / or the second adjustment factor are determined in one of the following ways:

[0147] The network (such as a base station) is configured via higher-layer signaling or defined by protocols;

[0148] Alternatively, it can be determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or defined by a protocol;

[0149] Here, the aforementioned higher-layer signaling can specifically be one or more of Radio Resource Control (RRC) signaling, Media Access Control and Control Unit (MAC CE) signaling, and System Information Block (SIB) signaling. The first adjustment factor or the second adjustment factor can be configured for each PUCCH format or for each PUCCH resource.

[0150] Implementation method 4:

[0151] In implementation method 4, the PUCCH resource configuration information corresponding to the third PUCCH is configured with a first maximum code rate and / or a second maximum code rate. For example, the third PUCCH configuration is a PUCCH configuration configured for transmitting the first UCI and the second UCI, and the resource configuration information corresponding to the third PUCCH is configured with a first maximum code rate and a second maximum code rate. In this case, in step 51 above, the terminal can determine that the code rate of the first UCI is the first maximum code rate and the code rate of the second UCI is the second maximum code rate.

[0152] Here, the correspondence between the first maximum code rate and the second maximum code rate configured in the resource configuration information corresponding to the third PUCCH, and the first UCI and the second UCI, can be configured by the network through higher-layer signaling or predefined, such as defined by relevant protocols.

[0153] Through the above various implementation methods, the code rates of the first UCI and the second UCI can be determined, and then in step 51 above, the first UCI and the second UCI are encoded according to the code rates of the first UCI and the second UCI.

[0154] Additionally, it should be noted that in this embodiment of the invention, among the at least two overlapping PUCCHs to be transmitted by the terminal, there is temporal overlap between any two PUCCHs (which may be complete or partial overlap). Preferably, the at least two PUCCHs include two different priority indices, namely the first priority index and the second priority index.

[0155] The method of the present invention will be further described below from the perspective of the base station.

[0156] Please refer to Figure 6 The physical uplink control channel transmission method provided in this embodiment of the invention, when applied to the base station side, includes:

[0157] Step 61: When the terminal determines or is about to overlap at least two PUCCHs, the base station receives the first UCI and the second UCI sent by the terminal on the third PUCCH. The at least two PUCCHs include the first PUCCH and the second PUCCH. The first PUCCH is a first priority index that carries or corresponds to the first UCI. The second PUCCH is a second priority index that carries or corresponds to the second UCI. The first UCI and the second UCI use different code rates.

[0158] Through the above steps, embodiments of the present invention can receive UCI originally carried (beared) in at least two PUCCHs (or corresponding to at least two PUCCHs) in one PUCCH. Furthermore, for UCI originally carried (beared) in PUCCHs with different priority indices, embodiments of the present invention can use different code rates for encoding and transmission, thereby ensuring the needs of different services and improving the system spectrum efficiency.

[0159] In this embodiment of the invention, when the base station receives the first UCI and the second UCI on the third PUCCH, it may specifically include: determining the third PUCCH according to the third DCI, wherein the third DCI is used to indicate the transmission of the third PUCCH.

[0160] In this embodiment of the invention, the third DCI may be a DCI indicating the transmission of the first PUCCH or the second PUCCH, wherein the first PUCCH and the second PUCCH overlap, and optionally, the first PUCCH and the second PUCCH are in the same time slot / sub-time slot. The third DCI is the last DCI received between the first DCI and the second DCI. Here, the first DCI is used to indicate the transmission of the first PUCCH, and the second DCI is used for the transmission of the second PUCCH.

[0161] The third DCI is a first DCI used to indicate the transmission of the first PUCCH, and the first DCI is the latest DCI sent to the terminal among the DCIs scheduling the at least two PUCCHs. The third DCI is a second DCI used to indicate the transmission of the second PUCCH, and the second DCI is the latest DCI sent to the terminal among the DCIs scheduling the at least two PUCCHs.

[0162] The third PUCCH is one of at least one PUCCH resource configured in the third PUCCH configuration (third PUCCH-Config). Specifically, the PUCCH resource is configured by PUCCH resource configuration information. More specifically, the third PUCCH configuration can be the PUCCH configuration corresponding to one of the at least two PUCCHs, or it can be a PUCCH configuration other than the at least two PUCCHs.

[0163] 1) The third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI.

[0164] In other words, the third PUCCH configuration is either the PUCCH configuration corresponding to the priority index of the first PUCCH, or the PUCCH configuration corresponding to the first UCI. It can be understood that the PUCCH configuration corresponding to the first UCI and the PUCCH configuration corresponding to the priority index of the first PUCCH are different descriptions of the same PUCCH configuration. Similarly, the same applies to the PUCCH configuration corresponding to the second UCI.

[0165] 2) The third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI.

[0166] In other words, the third PUCCH configuration is either the PUCCH configuration corresponding to the priority index of the second PUCCH, or the PUCCH configuration corresponding to the second UCI. It is understood that the PUCCH configuration corresponding to the second UCI and the PUCCH configuration corresponding to the priority index of the second PUCCH are different descriptions of the same PUCCH configuration.

[0167] 3) The third PUCCH configuration is the PUCCH configuration configured for transmitting the first UCI and the second UCI.

[0168] Here, the base station can additionally configure a third PUCCH configuration for transmitting the first UCI and the second UCI. Through this third PUCCH configuration, at least one PUCCH resource for transmitting the first UCI and the second UCI can be configured.

[0169] The following provides several ways to determine the bitrate of the first UCI and the second UCI.

[0170] In the following implementations 1 to 3, the PUCCH resource configuration information corresponding to the third PUCCH is configured with a maximum bit rate. The PUCCH resource configuration information corresponding to the first PUCCH is configured with at most one maximum bit rate. The PUCCH resource configuration information corresponding to the second PUCCH is configured with at most one maximum bit rate.

[0171] Implementation method 1:

[0172] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs transmitted by each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the second PUCCH.

[0173] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs indicating the transmission of each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the first PUCCH, and determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH.

[0174] Implementation method 2:

[0175] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs indicating the transmission of each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine the code rate of the second UCI based on the code rate of the first UCI.

[0176] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs indicating the transmission of each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH, and determine the code rate of the first UCI based on the code rate of the second UCI.

[0177] Implementation method 3:

[0178] When the third PUCCH configuration is the priority index of the first PUCCH or the PUCCH configuration corresponding to the first UCI, the first DCI indicating the transmission of the first PUCCH is the last received DCI among all DCIs indicating the transmission of each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the first UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH. If the PUCCH resource configuration information corresponding to the second PUCCH is configured with a maximum code rate, then the code rate of the second UCI is determined to be the maximum code rate configured by the PUCCH resource configuration information corresponding to the second PUCCH; otherwise, if the PUCCH resource configuration information corresponding to the second PUCCH is not configured with a maximum code rate, then the code rate of the second UCI is determined to be the code rate of the first UCI plus, minus, multiplied, or divided by a third adjustment factor.

[0179] When the third PUCCH configuration is the priority index of the second PUCCH or the PUCCH configuration corresponding to the second UCI, the first DCI indicating the transmission of the second PUCCH is the last received DCI among all DCIs indicating the transmission of each of the at least two PUCCHs. In step 61 above, when the base station receives the first UCI and the second UCI on the third PUCCH, it can determine that the code rate of the second UCI is the maximum code rate configured by the PUCCH resource configuration information corresponding to the third PUCCH. If the PUCCH resource configuration information corresponding to the first PUCCH is configured with a maximum code rate, then the code rate of the first UCI is determined to be the maximum code rate configured by the PUCCH resource configuration information corresponding to the first PUCCH; otherwise, the code rate of the first UCI is determined to be the code rate of the second UCI plus, minus, multiplied, or divided by a fourth adjustment factor.

[0180] In implementations 2 and 3 above, the bitrate of the second UCI is determined based on the bitrate of the first UCI. Specifically, the bitrate of the second UCI can be determined by adding, subtracting, multiplying, or dividing the bitrate of the first UCI by a first adjustment factor. Similarly, the bitrate of the first UCI can be determined based on the bitrate of the second UCI by adding, subtracting, multiplying, or dividing the bitrate of the second UCI by a second adjustment factor.

[0181] The first adjustment factor can be determined in one of the following ways:

[0182] A) The network (such as a base station) is configured or predefined through higher-layer signaling, such as through relevant protocols.

[0183] B) Determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or predefined, such as in a protocol.

[0184] Similarly, the second adjustment factor can also be determined in one of the following ways:

[0185] A) The network (such as a base station) is configured or predefined through higher-layer signaling, such as through relevant protocols.

[0186] B) Determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or predefined, such as in a protocol.

[0187] The first adjustment factor and / or the second adjustment factor are determined in one of the following ways:

[0188] The network (such as a base station) is configured via higher-layer signaling or defined by protocols;

[0189] Alternatively, it can be determined from a set of values ​​based on a preset DCI, the set of values ​​being configured by the network through higher-layer signaling or defined by a protocol;

[0190] Here, the aforementioned higher-layer signaling can specifically be one or more of Radio Resource Control (RRC) signaling, Media Access Control and Control Unit (MAC CE) signaling, and System Information Block (SIB) signaling. The first adjustment factor or the second adjustment factor can be configured for each PUCCH format or for each PUCCH resource.

[0191] Implementation method 4:

[0192] In implementation method 4, the PUCCH resource configuration information corresponding to the third PUCCH is configured with a first maximum code rate and / or a second maximum code rate. For example, the third PUCCH configuration is a PUCCH configuration configured for transmitting the first UCI and the second UCI, and the resource configuration information corresponding to the third PUCCH is configured with a first maximum code rate and a second maximum code rate. Alternatively, the third PUCCH configuration can also be a PUCCH configuration corresponding to the first priority index or a PUCCH configuration corresponding to the second priority index, and the resource configuration information corresponding to the third PUCCH can also be configured with a first maximum code rate and a second maximum code rate. In this case, in step 61 above, the base station can determine that the code rate of the first UCI is the first maximum code rate and the code rate of the second UCI is the second maximum code rate.

[0193] Here, the correspondence between the first maximum code rate and the second maximum code rate configured in the resource configuration information corresponding to the third PUCCH, and the first UCI and the second UCI, can be configured by the network through higher-layer signaling or predefined, such as defined by relevant protocols.

[0194] Through the above various implementation methods, the code rates of the first UCI and the second UCI can be determined, and then in step 61 above, the first UCI and the second UCI are decoded and received according to their code rates.

[0195] To better help understand the embodiments of the present invention, several examples are provided below. It should be noted that the following examples are illustrated with the first UCI being URLLC HARQ-ACK and the second UCI being eMBB HARQ-ACK, respectively, but the present invention is not limited to the above scenarios.

[0196] Example 1:

[0197] Configure two PUCCH configurations (PUCCH-Config), where the first PUCCH-Config corresponds to the first priority index uplink control information UCI (first UCI); and the second PUCCH-Config corresponds to the second priority index uplink control information UCI (second UCI).

[0198] like Figure 3 As shown in Scenario 1, assume PDSCH1 is an eMBB PDSCH and PDSCH2 is a URLLC PDSCH. The terminal first receives the eMBB PDSCH, and the PUCCH resource where its HARQ-ACK resides is... Figure 3 The first UCI (eMBB HARQ-ACK) is received by the terminal; the PUCCH resource where the HARQ-ACK is located is... Figure 3 The second UCI (URLLCHARQ-ACK) in the process timeline, when the processing timeline conditions are met, involves the terminal multiplexing the eMBB HARQ-ACK and URLLCHARQ-ACK information onto the third PUCCH resource for transmission. This third PUCCH resource is configured by the first PUCCH-Config and is indicated by the last received (last DCI format).

[0199] The code rate of the URLLC HARQ-ACK information is the maxCodeRate configured in the PUCCH resource URLLC HARQ-ACK configuration;

[0200] The code rate of the eMBB HARQ-ACK information is the maxCodeRate configured in the PUCCH resource eMBB HARQ-ACK;

[0201] Example 2:

[0202] Configure two PUCCH configurations (PUCCH-Config), where the first PUCCH-Config corresponds to the uplink control information (UCI) of the first priority index; and the second PUCCH-Config corresponds to the uplink control information (UCI) of the second priority index.

[0203] like Figure 3 As shown in Scenario 1, assume PDSCH1 is an eMBB PDSCH and PDSCH2 is a URLLC PDSCH. As shown in Scenario 1, the terminal first receives the eMBB PDSCH, and the PUCCH resource where its HARQ-ACK resides is... Figure 3 The first UCI (eMBB HARQ-ACK) in the process; the terminal then receives the URLLC PDSCH, and the PUCCH resource where its HARQ-ACK resides is... Figure 3 The second UCI (URLLC HARQ-ACK) in the process timeline, when the processing timeline conditions are met, involves the terminal multiplexing the eMBB HARQ-ACK information and the URLLC HARQ-ACK information onto the third PUCCH resource for transmission. This third PUCCH resource is configured by the first PUCCH-Config and is indicated by the last received (last DCI format).

[0204] The code rate of the URLLC HARQ-ACK information is the maxCodeRate configured in the PUCCH resource URLLC HARQ-ACK configuration;

[0205] The code rate of the eMBB HARQ-ACK information is the maxCodeRate configured for the PUCCH resource URLLC HARQ-ACK, plus / minus / multiply / divide by the first adjustment factor.

[0206] Example 3:

[0207] Configure two PUCCH-Configs: the first PUCCH-Config corresponds to the uplink control information (UCI) of the first priority index, and the second PUCCH-Config corresponds to the uplink control information (UCI) of the second priority index.

[0208] like Figure 3As shown in Scenario 1, the terminal first receives the eMBB PDSCH, and the PUCCH resource where its HARQ-ACK is located is... Figure 3 The first UCI (eMBB HARQ-ACK) is received by the terminal; the PUCCH resource containing the HARQ-ACK is... Figure 3 In the second UCI (URLLC HARQ-ACK), when the processing timeline conditions are met, the terminal multiplexes the eMBB HARQ-ACK information and the URLLC HARQ-ACK information on the third PUCCH resource for transmission. The third PUCCH resource is configured by the first PUCCH-Config and indicated by the last DCI format.

[0209] in,

[0210] The code rate of the URLLC HARQ-ACK information is the first maxCodeRate of the PUCCH resource URLLC HARQ-ACK configuration;

[0211] The code rate of the eMBB HARQ-ACK information is the second maxCodeRate configured in the PUCCH resource URLLC HARQ-ACK configuration;

[0212] Here, two maximum code rates (maxCodeRate) are configured for each PUCCH resource or per-PUCCH format.

[0213] Example 4:

[0214] Configure three PUCCH-Configs: the first PUCCH-Config corresponds to the first priority index uplink control information (UCI); the second PUCCH-Config corresponds to the second priority index uplink control information (UCI); and the third PUCCH-Config corresponds to the first priority index UCI and the second priority index UCI. That is, when the terminal needs to reuse the first priority index UCI and the second priority index UCI, the configuration of the third PUCCH-Config is used.

[0215] like Figure 3 As shown in Scenario 1, the terminal first receives the eMBB PDSCH, and the PUCCH resource where its HARQ-ACK is located is the eMBB HARQ-ACK shown in the diagram; the terminal then receives the URLLC PDSCH, and the PUCCH resource where its HARQ-ACK is located is... Figure 3In the URLLC HARQ-ACK section, when the processing timeline conditions are met, the terminal multiplexes the eMBB HARQ-ACK information and the URLLC HARQ-ACK information on the third PUCCH resource for transmission. This third PUCCH resource is configured in the third PUCCH-Config and indicated by the last DCI format.

[0216] The code rate of the URLLC HARQ-ACK information is determined to be the first maxCodeRate of the third PUCCH resource configuration;

[0217] The code rate for determining the eMBB HARQ-ACK information is the second maxCodeRate of the third PUCCH resource configuration.
