Description

A communication method, device and system

technical field

The present application relates to the field of wireless communication technologies, and in particular, to a communication method, device, and system.

Background technique

In the uplink transmission between network equipment and terminal equipment, an uplink time slot (slot) carries channels such as physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH). The network device may allocate time-frequency resources corresponding to one uplink time slot to the PUCCH and the PUSCH in a time-division or frequency-division manner.

The network device may allocate time-frequency resources corresponding to one uplink time slot to the PUCCH in a frequency hopping manner. Taking the configuration of PUCCH resources as an example, under the mechanism of frequency hopping in the frequency domain, the network device needs to configure a low-band resource block (RB) and a high- and low-band RB for the terminal device to carry PUCCH, that is, the network The device needs to configure two RBs for the terminal device to carry the PUCCH, as shown in Figure 1. But in fact, in the process of PUCCH jumping from the low frequency band to the high frequency band, the PUCCH does not completely occupy the RB in the low frequency band and the RB in the high frequency band, but occupies part of the time-frequency resources of the RB in the low frequency band and the RB in the high frequency band. Some time-frequency resources. Since the network equipment configures the PUCCH resources in units of RBs, the unoccupied time-frequency resources in the RBs cannot be allocated to the PUSCH or other terminal equipment, resulting in waste of resources and reduced utilization of resources.

Embodiments of the present application provide a communication method, apparatus, and system, so as to reduce PUCCH overhead and improve resource utilization.

In a first aspect, an embodiment of the present application provides a communication method, and the method may be executed by a network device, or may also be executed by a component of the network device (such as a processor, a chip, or a chip system, etc.).

As shown in FIG. 2 , the communication system 100 includes a network device 101 and at least one terminal device. The communication system 100 may include one or more terminal devices, and FIG. 2 takes two terminal devices as an example.

Exemplarily, the network device 101 may be an access network device, such as a radio access network (radio access network, RAN) device, which is a device that provides a wireless communication function for the terminal device 102 (and/or the terminal device 103 ).

In this embodiment of the present application, the device for implementing the function of the network device 101 may be the network device 101 ; it may also be a device capable of supporting the network device 101 to realize the function, such as a chip system, and the device may be installed in the network device 101 . In the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the device for implementing the functions of the network device 101 as the network device 101 as an example.

Exemplarily, a terminal device (eg, terminal device 102 or terminal device 103 ) may be referred to as a terminal for short, such as user equipment (user equipment, UE), which is a device with a wireless transceiver function. Terminal equipment can be deployed on land (such as vehicles, vehicles, high-speed rail or motor vehicles, etc.); can also be deployed on water (such as ships, etc.); can also be deployed in the air (such as aircraft, drones, balloons and satellites, etc.) .

In this embodiment of the present application, the apparatus for implementing the function of the terminal may be a terminal device; it may also be an apparatus capable of supporting the terminal device to implement the function, such as a chip system, and the apparatus may be installed in the terminal device. In this embodiment of the present application, the chip system may be composed of chips, or may include chips and other discrete devices. In the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the apparatus for realizing the function of the terminal device as the terminal device as an example.

The network architecture and service scenarios described above in the embodiments of the present application are for the purpose of illustrating the technical solutions of the embodiments of the present application more clearly, and do not constitute limitations on the technical solutions provided by the embodiments of the present application. The evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Some technical features involved in the embodiments of the present application are introduced below.

In the uplink transmission process, channels such as PUCCH and PUSCH can be simultaneously carried in one uplink time slot. The network device may allocate time-frequency resources corresponding to one uplink time slot to the PUCCH and the PUSCH in a time-division or frequency-division manner. For example, the network device may allocate time-frequency resources corresponding to one uplink time slot to the PUCCH and the PUSCH in units of RBs. The general principle for the network device to allocate the time-frequency resources corresponding to an uplink time slot to the PUCCH and PUSCH is as follows: under the condition that sufficient PUCCH resources are ensured, the PUCCH overhead is reduced as much as possible, so that more time-frequency resources can be allocated to PUSCH, thereby increasing the data transmission rate. PUCCH is mainly used to transmit uplink control information (UCI) of physical layer 1 or media access control layer 2 (physical layer 1/media access control layer 1, L1/L2) to support uplink and downlink data transmission. The UCI may include at least one of the following information:

(1) Uplink scheduling request (SR), which is used to request uplink resources. For example, when the terminal device has uplink data to transmit, the terminal device may send an SR to the network device to request the network device to configure uplink resources for data transmission.

(2) Hybrid automatic repeat request-positive acknowledgment or negative acknowledgment (hybrid automatic repeat request-acknowledgement/negative acknowledgment, HARQ-ACK/NACK), which is used to reply to the transmission of downlink data. For example, if the terminal device correctly receives and demodulates the downlink data sent by the network device, the terminal device feeds back ACK information to the network device through UCI, otherwise it feeds back NACK information.

(3) Channel state information (CSI), which is used to reflect channel properties. For example, CSI may include a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), a layer indicator (LI), a CSI reference signal resource indicator (CSI-RS resource indicator, CRI), synchronization signal and physical broadcast channel block resource indicator (synchronization signal and physical broadcast channel block resource indicator, SSBRI), Layer 1 Reference Signal Received Power (Layer 1 Reference Signal Received Power, L1-RSRP) at least one of them.

According to the symbol length occupied by PUCCH and the number of bits occupied by UCI, the 3rd generation partnership project (3GPP) protocol defines five PUCCH formats, which are PUCCH format 0 and PUCCH format 1. , PUCCH format 2, PUCCH format 3, and PUCCH format 4. Among them, PUCCH format 0 and PUCCH format 2 are PUCCH in short format, and PUCCH format 1, PUCCH format 3 and PUCCH format 4 are PUCCH in long format. The PUCCH in the short format occupies 1 to 2 symbols and can carry information of 1 to 2 bits, and the PUCCH in the long format occupies 4 to 14 symbols and can carry information larger than 2 bits. PUCCH formats 0 to 4 all support frequency domain frequency hopping to obtain frequency domain diversity gain.

In addition, PUCCH format 0, PUCCH format 1 and PUCCH format 4 support code division multiplexing, while PUCCH format 2 and PUCCH format 3 do not support code division multiplexing (it can be understood that PUCCH format 2 and PUCCH format 3 support double the code division multiplexing use). Among them, PUCCH format 0 uses cyclic shift to realize code division multiplexing, and the available cyclic shifts are 0 to 11; PUCCH format 1 uses cyclic shift and time-domain orthogonal sequence to realize code division multiplexing, and the available cyclic shifts are The bits are 0 to 11, the available time domain orthogonal sequences are 0 to 6, and the code division multiplexing multiple is equal to the product of the available number of cyclic shifts and the available number of time domain orthogonal sequences; PUCCH format 4 uses time domain orthogonality Sequence to realize code division multiplexing, the available time domain orthogonal sequence is 0～3.

PUCCH can be further divided into common PUCCH and dedicated PUCCH. For example, for a terminal device, the common PUCCH is configured before the dedicated PUCCH, and the common PUCCH is mainly used to transmit HARQ-ACK/NACK information in the initial bandwidth part (band width part, BWP). Before RRC is established between the network device and the terminal device, the terminal device cannot obtain the dedicated PUCCH configuration, so it can only use the PUCCH configuration configured in the initial BWP. Once the RRC between the network device and the terminal device is established, the terminal device has If the dedicated PUCCH is selected, the dedicated PUCCH is used to communicate with the network device. The 3GPP protocol defines 16 common PUCCH resource configurations. Each common PUCCH resource configuration can include an index (index), PUCCH format, first symbol position (first symbol), symbol length (number of symbols), RB The offset (RB offset) and the initial cyclic shift set (set of initial cyclic shift indexes). The 16 common PUCCH resource configurations are shown in Table 1.

Table 1: 16 common PUCCH resource configurations

It can be seen from Table 1 that the format of the common PUCCH is PUCCH format 0 or PUCCH format 1. When the common PUCCH format is PUCCH format 1, the initial cyclic shift set is a subset of {0, 3, 6, 9}, and the number of cyclic shifts can be 2 (eg {0, 6}), or is 4 (eg {0,3,6,9}).

Exemplarily, the position index of the RB of the common PUCCH can be determined by formula (1):

in,

Represents a round-down operation, r _PUCCH may represent the position index of the RB of the common PUCCH, n _{CCE, 0} may represent the index of the first control-channel element (CCE), and N _CCE may represent the control resource set The number of CCEs in (coreset), Δ _PRI may represent the value of the PUCCH resource indication field given by downlink control channel (DCI).

The common PUCCH can be transmitted by frequency-domain frequency hopping to obtain frequency-domain diversity gain. For example, when the position index of the RB of the common PUCCH is less than or equal to 7, that is,

When , the position index of the RB of the first hop (first hop) PUCCH can be

The location index of the RB of the second hop (second hop) PUCCH may be

When the position index of the RB of the common PUCCH is greater than or equal to 8, that is,

, the position index of the RB of the first hop PUCCH can be

The location index of the RB of the second hop (second hop) PUCCH may be

in,

represents the RB offset, N _CS represents the number of cyclic shifts,

Indicates the number of RBs included in the BWP. For example, when the number of CCEs in the control resource set is 8, the RB offset is 0, and the number of cyclic shifts is 2, the position index of the RB of the first hop PUCCH and the position index of the RB of the second hop PUCCH can be as shown in the table 2 shown. For another example, when the number of CCEs in the control resource set is 8, the RB offset is 0, and the number of cyclic shifts is 4, the position index of the RB of the first hop PUCCH and the position index of the RB of the second hop PUCCH can be as follows: shown in Table 3.

Table 2: When N _CS =2, the position index of the RB of the first hop PUCCH and the position index of the RB of the second hop PUCCH

Table 3: When N _CS =4, the position index of the RB of the first hop PUCCH and the position index of the RB of the second hop PUCCH

It can be seen from Table 2 that the position index of the RB occupied by the common PUCCH in the frequency domain can be 0 and 47, or 1 and 46, or 2 and 45, or 3 and 44, that is, the common PUCCH is in the frequency domain. The number of RBs occupied on the domain is 8 RBs. It can be seen from Table 3 that the position indices of the RBs occupied by the common PUCCH in the frequency domain may be 0 and 47, or 1 and 46, that is, the number of RBs occupied by the common PUCCH in the frequency domain is 4 RBs. That is to say, the number of RBs occupied by the public PUCCH in the current protocol in the frequency domain is 4 RBs or 8 RBs.

When the format of the public PUCCH is PUCCH format 1 and the format of the dedicated PUCCH is PUCCH format 1, although the format of the public PUCCH is the same as the format of the dedicated PUCCH, the network equipment still needs to be independently configured in RB units and at the cell level. The common PUCCH resource and the dedicated PUCCH resource, that is, the common PUCCH resource and the dedicated PUCCH resource, are frequency-divided in the frequency domain within a time slot. And when the public PUCCH (or the dedicated PUCCH) is transmitted using frequency domain frequency hopping, the network device needs to configure an even number of RBs for the public PUCCH (or the dedicated PUCCH). Taking the network device configuring a public PUCCH (format 1) for terminal device 1 and configuring a dedicated PUCCH (format 1) for terminal device 2 as an example, the network device can configure two RBs in the initial BWP to the public PUCCH, so that The terminal device 1 can establish an RRC connection with the network device based on the public PUCCH; the network device can configure the 2 RBs in the full band except the initial BWP to the dedicated PUCCH, so that the terminal device 2 can communicate with the network device based on the dedicated PUCCH. The network device performs data transmission; the network device may also configure the two idle RBs in the initial BWP to a dedicated PUCCH to improve resource utilization, as shown in FIG. 3A . If the initial BWP configuration is full-band, the network device may configure 2 RBs in the full-band to the public PUCCH and 2 RBs to the dedicated PUCCH, as shown in FIG. 3B . It can be understood that FIG. 3A and FIG. 3B are only an example of PUCCH resource configuration, which is not limited in the present application.

Since the common PUCCH resources and the dedicated PUCCH resources are configured at the cell level, the common PUCCH resources and the dedicated PUCCH resources are frequency-divided in the frequency domain within a time slot. Therefore, in a time slot, even if the public PUCCH resources (or the dedicated PUCCH resources) are not used up, the PUSCH cannot use the remaining resources of the public PUCCH (or the remaining resources of the dedicated PUCCH), which will lead to waste of resources. Reduce upstream data channel capacity.

When the dedicated PUCCH formats are PUCCH format 3 and PUCCH format 4, although PUCCH format 3 and PUCCH format 4 are basically the same in terms of protocol functions, the network device also needs to independently configure PUCCH format 3 in RB units and at the cell level. The resources and the resources of the PUCCH format 4, that is, the resources of the PUCCH format 3 and the resources of the PUCCH format 4 are frequency-divided in the frequency domain within one time slot. And when PUCCH format 3 (or PUCCH format 4) uses frequency-domain frequency hopping for transmission, the network device needs to configure an even number of RBs for PUCCH format 3 (or PUCCH format 4). Taking the network device configuring PUCCH format 3 for terminal device 1 and configuring PUCCH format 4 for terminal device 2 as an example, the network device can configure the 2 RBs in the full band except the initial BWP to PUCCH format 3, so that terminal device 1 Data transmission can be performed with the network device based on the PUCCH format 3; the network device can configure the 2 RBs in the full band except the initial BWP to the PUCCH format 4, so that the terminal device 2 can perform data transmission with the network device based on the PUCCH format 4. Data transfer, as shown in Figure 4A. If the initial BWP configuration is full-band, the network device may configure 2 RBs in the full-band to PUCCH format 3 and 2 RBs to PUCCH format 4, as shown in FIG. 4B . It can be understood that FIG. 4A and FIG. 4B are only an example of PUCCH resource configuration, which is not limited in the present application.

Similarly, since PUCCH format 3 and PUCCH format 4 are configured at the cell level, PUCCH format 3 and PUCCH format 4 are frequency-divided in the frequency domain within one time slot. Therefore, in a time slot, even if the resources of PUCCH format 3 (or the resources of PUCCH format 4) are not used up, the PUSCH cannot use the remaining resources of PUCCH format 3 (or the remaining resources of PUCCH format 4), which will result in resource waste, reducing the capacity of the uplink data channel.

In view of this, an embodiment of the present application provides a communication method, in which a network device configures a first resource in a first RB for a first terminal device, and configures a second resource in a second RB for a second terminal device, respectively, The first resource is used to carry the first PUCCH, and the second resource is used to carry the second PUCCH. Since different PUCCHs can be multiplexed on one RB, the waste of the remaining resources of the first PUCCH (or the second PUCCH) can be avoided, and the number of RBs occupied by the PUCCH in one time slot can be reduced, so that more time slots can be used. The frequency resources are reserved for PUSCH use, which can improve resource utilization and increase uplink data channel capacity.

FIG. 5 is a schematic flowchart of a communication method provided by an embodiment of the present application, and the method may be applied to the communication system 100 shown in FIG. 2 . The network device in this embodiment of the present application may be the network device 101 shown in FIG. 2 , the first terminal device may be the terminal device 102 shown in FIG. 2 , and the second terminal device may be the terminal device 103 shown in FIG. 2 . It can be understood that, in this embodiment of the present application, the steps performed by the network device may also be specifically performed by a module or component of the network device, for example, may be performed by a chip or a chip system in the network device; the steps performed by the terminal device It can also be specifically executed by a module or component of the terminal device, for example, it can be executed by a chip or a chip system in the terminal device. As shown in Figure 5, the method may include:

S501: The network device sends first information to the first terminal device. Correspondingly, the first terminal device receives the first information.

The first information may be used to indicate the first resource in the first RB, and the first resource may be used to carry the first PUCCH.

As an example, the first PUCCH may be a common PUCCH, and the format of the first PUCCH is PUCCH format 1. For example, the network device may broadcast first information, where the first information is used to indicate the first resource in the first RB, and the first resource is used to carry the first PUCCH; the first terminal device may receive the first information broadcast by the network device, Therefore, the first terminal device can establish an RRC connection with the network device based on the first resource. For example, the first information may be a system information block (SIB).

As another example, the first PUCCH is a PUCCH that can be dedicated, and the format of the first PUCCH is PUCCH format 3. For example, the network device may send first information to the first terminal device through an RRC connection with the first terminal device, where the first information is used to indicate the first resource in the first RB, and the first resource is used to carry the first PUCCH; the first terminal device can receive the first information from the network device, so that the first terminal device can perform data transmission with the network device based on the first resource. For example, the first information may be RRC signaling, or DCI signaling, or MAC signaling, or the like.

S502: The network device sends the second information to the second terminal device. Correspondingly, the second terminal device receives the second information.

The second information may be used to indicate a second resource in the first RB, and the second resource may be used to carry the second PUCCH.

As an example, the second PUCCH may be a dedicated PUCCH, and the format of the second PUCCH is PUCCH format 1. For example, the network device may send second information to the second terminal device through an RRC connection with the second terminal device, where the second information is used to indicate the second resource in the first RB, and the second resource is used to carry the second PUCCH; the second terminal device can receive the second information from the network device, so that the second terminal device can perform data transmission with the network device based on the second resource. For example, the second information may be RRC signaling, or DCI signaling, or MAC signaling, or the like.

As another example, the second PUCCH is a PUCCH that can be dedicated, and the format of the second PUCCH is PUCCH format 4. For example, the network device may send second information to the second terminal device through an RRC connection with the second terminal device, where the second information is used to indicate the second resource in the first RB, and the second resource is used to carry the second PUCCH; the second terminal device can receive the second information from the network device, so that the second terminal device can perform data transmission with the network device based on the second resource. For example, the second information may be RRC signaling, or DCI signaling, or MAC signaling, or the like.

In a possible implementation manner, the service type corresponding to the first PUCCH may be different from the service type corresponding to the second PUCCH. For example, the service type corresponding to the first PUCCH is an access service, and the service corresponding to the second PUCCH is a data transmission service. That is, the first PUCCH may be a public PUCCH, and the second PUCCH may be a dedicated PUCCH. Optionally, the format of the first PUCCH may be PUCCH format 1, and the format of the second PUCCH may be PUCCH format 2. In this way, the network device can multiplex PUCCH formats of different service types into one RB, and can improve the utilization of the remaining resources of the common PUCCH (or dedicated PUCCH format) under the condition that the PUCCH resources are not limited. rate, so that more time-frequency resources can be allocated to the PUSCH, thereby improving the data transmission rate.

For example, when the first PUCCH is a public PUCCH, the format of the first PUCCH is PUCCH format 1, the second PUCCH is a dedicated PUCCH, and the format of the second PUCCH is PUCCH format 1, the first RB may include In a code division sequence, the first resource may be a first subsequence in the first code division sequence, and the second resource may be a subsequence other than the first subsequence in the first code division sequence. For example, the first code division sequence may be a code division sequence formed by a first time domain-orthogonal cover code (TD-OCC) and a first cyclic shift, and the first TD-OCC may be { Any element in 0,1,2,3,4,5,6}, the first cyclic shift can be {0,1,2,3,4,5,6,7,8,9,10, 11} any of the elements. For example, the second code division sequence may be a code division sequence formed by the second TD-OCC and the second cyclic shift, the second TD-OCC may be 0, and the second cyclic shift may be {0, 3, 6, 9 any element in }.

For example, if the first resource is a first subsequence composed of a second TD-OCC of 0 and a second cyclic shift of 0 and 6 (that is, the first resource includes a first subsequence composed of a TD-OCC of 0 and a cyclic shift of 0) subsequence, and a subsequence composed of TD-OCC of 0 and cyclic shift of 6), the second resource can be TD-OCC of 0 and cyclic shift of {1, 2, 3, 4, 5, 7, 8 ,9,10,11} The subsequence composed of any element, TD-OCC is 1, cyclic displacement is {0,1,2,3,4,5,6,7,8,9,10,11 The subsequence composed of any element in }, TD-OCC is 2, and the cyclic displacement is any element in {0,1,2,3,4,5,6,7,8,9,10,11} The formed subsequence, the TD-OCC is 3, the cyclic displacement is the subsequence formed by any element in {0,1,2,3,4,5,6,7,8,9,10,11}, TD -OCC is 4, cyclic displacement is a subsequence composed of any element in {0,1,2,3,4,5,6,7,8,9,10,11}, TD-OCC is 5, cyclic The displacement is a subsequence composed of any element in {0,1,2,3,4,5,6,7,8,9,10,11}, or the TD-OCC is 6 and the ring displacement is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} at least one of the subsequences formed by any element.

Exemplarily, the number of the first RBs may be N, where N is an integer greater than 0 and less than 9. Since the common PUCCH can occupy at most 8 RBs in a time slot, the dedicated PUCCH can use time-frequency resources not occupied by the common PUCCH in at least one of the 8 RBs, thereby reducing the overhead of the dedicated PUCCH.

In another possible implementation manner, the format of the first PUCCH and the format of the second PUCCH may be different. For example, the format of the first PUCCH is PUCCH format 3, and the format of the second PUCCH is PUCCH format 4. In this way, the network device can multiplex different PUCCH formats into one RB. Under the condition that the PUCCH resources are not limited, the utilization rate of the remaining resources of PUCCH format 3 (or PUCCH format 4) can be improved, so that More time-frequency resources can be allocated to the PUSCH, thereby increasing the data transmission rate.

Exemplarily, when the format of the first PUCCH is PUCCH format 3 and the format of the second PUCCH is PUCCH format 4, the first resource and the second resource may be located in the same RB, and the first resource and the second resource are in the time domain can be staggered.

For example, as shown in FIG. 6A , when the frequency domain frequency hopping method is used for transmission, the network device can configure one RB in the low frequency band for the first terminal device to carry the first PUCCH, and configure one RB in the high frequency band for the first PUCCH Bearing the first PUCCH. Similarly, the network device may configure one RB in the low frequency band for the second terminal device to carry the second PUCCH, and configure one RB in the high frequency band to carry the second PUCCH. As can be seen from FIG. 6A , on the one hand, neither the first PUCCH nor the second PUCCH can completely occupy the entire RB, and there are remaining resources, resulting in a waste of resources; on the other hand, the network device needs to be the first terminal device (or the second terminal device) An even number of RBs are configured to carry the first PUCCH (or the second PUCCH), which has poor adaptability.

In the above steps S501 and S502, the network device may configure the first resource and the second resource of the same middle RB to the first PUCCH and the second PUCCH respectively, so that the first PUCCH and the second PUCCH can multiplex the same RB time-frequency resources, thereby improving resource utilization. For example, the network device may configure the first half time slot in the first RB of the low frequency band to the second PUCCH, and configure the second half time slot in the first RB of the low frequency band to the first PUCCH; The first half time slot in the first RB of the frequency band is allocated to the first PUCCH, and the second half time slot in the first RB of the high frequency band is allocated to the second PUCCH, as shown in FIG. 6B . For another example, the network device may configure the first half time slot in the first RB of the low frequency band to the first PUCCH, and configure the second half time slot in the first RB of the low frequency band to the second PUCCH; The first half time slot in the first RB of the high frequency band is allocated to the second PUCCH, and the second half time slot of the first RB of the high frequency band is allocated to the first PUCCH, as shown in FIG. 6B .

Exemplarily, when the first resource can be used for the resource of the first hop of the first PUCCH, the second resource can be used for the resource of the first hop of the second PUCCH, or the resource of the second hop of the second PUCCH. Alternatively, when the first resource may be used for the resource of the first PUCCH second hop, the second resource may be used for the resource of the second PUCCH first hop, or may be used for the second PUCCH second hop resource. This application is not limited to this.

Optionally, the first PUCCH may occupy an odd number of RBs or an even number of RBs. For example, the network device may configure an even number of RBs for the first PUCCH in the manner shown in FIG. 1 or FIG. 6A . For another example, the network device may configure 5 RBs for the first PUCCH, 4 RBs among the 5 RBs may be individually configured for the first PUCCH according to the manner shown in FIG. 1 or FIG. 6A , and the remaining 1 RBs among the 5 RBs The RBs may be allocated to the first PUCCH and the second PUCCH in the manner shown in FIG. 6B or FIG. 6C . That is, the first PUCCH and the second PUCCH may share the remaining 1 RB.

Similarly, the second PUCCH may also occupy an odd number of RBs or an even number of RBs. For example, the network device may configure an even number of RBs for the second PUCCH in the manner shown in FIG. 1 or FIG. 6A . For another example, the network device may configure 3 RBs for the second PUCCH, 2 RBs in the 3 RBs may be individually configured for the second PUCCH in the manner shown in FIG. 1 or FIG. 6A , and the remaining 1 RBs in the 3 RBs The RBs may be allocated to the first PUCCH and the second PUCCH in the manner shown in FIG. 6B or FIG. 6C . That is, the first PUCCH and the second PUCCH may share the remaining 1 RB.

S503: The first terminal device sends the first PUCCH to the network device. Correspondingly, the network device receives the first PUCCH.

For example, the first terminal device may send the first PUCCH to the network device through the first resource in the first RB. Correspondingly, the network device may receive the first PUCCH from the first terminal device by detecting the first resource in the first RB.

As an example, the first PUCCH may be a common PUCCH, and the format of the first PUCCH is PUCCH format 1. When the first PUCCH is a common PUCCH, the first PUCCH can be used for establishing an RRC connection between the first terminal device and the network device.

As another example, the first PUCCH is a PUCCH that can be dedicated, and the format of the first PUCCH is PUCCH format 3. When the first PUCCH is a dedicated PUCCH, the first PUCCH can be used for data transmission between the first terminal device and the network device.

S504: The second terminal device sends the second PUCCH to the network device. Correspondingly, the network device receives the second PUCCH.

For example, the second terminal device may send the second PUCCH to the network device through the second resource in the first RB. Correspondingly, the network device may receive the second PUCCH from the second terminal device by detecting the second resource in the first RB.

As an example, the second PUCCH may be a dedicated PUCCH. For example, the format of the second PUCCH is PUCCH format 1. For another example, the format of the second PUCCH may be PUCCH format 4. The second PUCCH can be used for data transmission between the second terminal device and the network device.

It should be noted that, the execution sequence of step S501 to step S504 shown in FIG. 5 is only an example, which is not limited in this embodiment of the present application. For example, the network device can first send the first information to the first terminal device, and then send the second information to the second terminal device; or, the network device can also send the second information to the second terminal device first, and then send the second information to the first terminal device. Send the first information; or, the network device may also send the first information to the first terminal device and send the second information to the second terminal device at the same time. For another example, the network device may first receive the first PUCCH from the first terminal device, and then receive the second PUCCH from the second terminal device; or, the network device may first receive the second PUCCH from the second terminal device, and then receive the second PUCCH from the second terminal device. The first PUCCH of the first terminal device; or, the network device may also receive the first PUCCH of the first terminal device and the second PUCCH of the second terminal device at the same time.

In the above-mentioned embodiment of the present application, the network device configures the first resource in the first RB for the first terminal device, and configures the second resource in the second RB for the second terminal device, and the first resource is used to carry the first PUCCH, The second resource is used to carry the second PUCCH. This means that different PUCCHs can be multiplexed on the same RB, which can avoid wasting the remaining resources of the first PUCCH (or the second PUCCH) due to allocating the entire RB to the first PUCCH (or the second PUCCH). problems, thereby improving resource utilization. Since different PUCCHs can be multiplexed on one RB, the number of RBs occupied by PUCCH in one time slot can be reduced, so more time-frequency resources in one time slot can be reserved for PUSCH, thereby increasing uplink data channels capacity and improve data transmission efficiency.
