Description

Method and equipment for configuring physical uplink control channel resources

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring Physical Uplink Control Channel (PUCCH) resources.

Background

In a New Radio (NR) communication system, a terminal may transmit two non-overlapping PUCCHs in a slot (slot) in a time slot (slot), and in addition, the NR system also supports PUCCH frequency hopping, where two frequency hopping resources are not overlapped in the time slot.

The network side may configure the terminal to transmit PUCCH resources and spatial relationship (spatial relationship) of the PUCCH through Radio Resource Control (RRC) signaling. The spatial relationship of the PUCCH refers to a spatial relationship between a Reference Signal and the PUCCH, where the Reference Signal may be specifically a Synchronization Signal Block (SSB), a Channel State Information Reference Signal (CSI-RS), or a Sounding Reference Signal (SRS). The network side may activate one of the above spatial relationships through a Media Access Control (MAC) command.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in this embodiment. The network-side device 12 may be a Base Station and/or a core network element, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present application only takes the Base Station in the NR system as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the 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, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The 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 base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise 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). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

Improving the transmission reliability of the PUCCH is very important to improve the performance of the communication system. The NR PUCCH transmission mechanism only supports PUCCH transmission on one continuous frequency domain resource in the same time domain, and when there is instantaneous deep fading in the frequency domain channel, the transmission reliability of PUCCH is severely affected. For another example, when the PUCCH configures frequency hopping, multiple transmission/reception points (TRPs) may be deployed in the same cell or different beams of the same TRP may receive signals from beams of the same terminal. At this time, how to utilize these beams to improve the reliability of the PUCCH is also a problem to be solved.

At present, a PUCCH transmission mechanism of an NR system in the prior art does not support transmission of two PUCCHs in the same time domain, and cannot improve reliability of the PUCCHs by repeating transmission in the frequency domain. For frequency hopping PUCCH, two spatial relationships of PUCCH activated at a time are assumed, and there is no corresponding transmission mechanism to further improve the transmission reliability of PUCCH.

It can be seen that the PUCCH resource configuration in the prior art is not flexible enough, and is difficult to adapt to different application environments, which is not beneficial to improving the transmission reliability of the PUCCH.

In order to solve at least one of the above problems, at least one embodiment of the present application provides a method for configuring physical uplink control channel resources, which is applied to the above-mentioned network side device. As shown in fig. 2, the method includes:

step 21, configuring PUCCH resources for the terminal, where the PUCCH resources include a first part of resources and a second part of resources, where the first part of resources and the second part of resources are used to carry the same uplink control information or different parts of the same uplink control information, and both the first part of resources and the second part of resources are continuous frequency domain resources and there is no overlapping portion in the frequency domain.

Here, in this embodiment of the present application, the PUCCH resource configured for the terminal by the network side device includes two parts (i.e., a first part resource and a second part resource), where the first part resource and the second part resource are both continuous resources in a frequency domain, and may partially overlap or completely overlap or do not have any overlap in a time domain. The specific configuration mode may be that the network side device performs configuration through higher layer signaling (such as RRC signaling) or physical layer signaling (such as MAC CE or DCI). Several examples of two partial resources are given in fig. 3, each small square in fig. 3 corresponds to one time domain symbol, and each dashed box represents one PUCCH resource, which includes a first partial resource and a second partial resource.

For example, the first partial resource 311 and the second partial resource 312 in the dotted box 31 each include 2 time domain symbols. It can be seen that the first partial resource 311 and the second partial resource 312 completely overlap in the time domain, and there is no overlapping portion in the frequency domain. For another example, the first partial resource 321 and the second partial resource 322 in the virtual frame 32 partially overlap in the time domain, and there is no overlapping portion in the frequency domain. For another example, the first partial resource 331 and the second partial resource 332 in the virtual frame 33 do not have an overlapping portion in the time domain, and do not have an overlapping portion in the frequency domain. The PUCCH resources indicated by the above-mentioned

dotted boxes

31 and 32 may be regarded as two-part resources, which are frequency division resources, and the PUCCH resources indicated by the above-mentioned dotted box 33 may be regarded as a kind of frequency hopping resource.

Step 22, activating the spatial relationship of the PUCCH resources, so that the first part of resources and the second part of resources correspond to different spatial relationships, respectively, or the first part of resources and the second part of resources correspond to the same spatial relationship.

That is, the spatial relationship of activation may be: the first part of resources and the second part of resources correspond to different spatial relationships respectively; or the first part of resources and the second part of resources correspond to the same spatial relationship.

Here, the spatial relationship of the PUCCH refers to a spatial relationship of the reference signal and the PUCCH. Generally, a network side device may configure multiple spatial relationships of PUCCH resources for a terminal through high-level signaling, and then activate one or more spatial relationships through physical layer signaling as needed. Each spatial relationship may correspond to a receive beam of the network-side device. In this embodiment, two partial resources of the same PUCCH resource may correspond to different spatial relationships, or both correspond to the same spatial relationship.

Through the steps, the embodiment of the application realizes flexible configuration of PUCCH resources and spatial relationship, thereby providing support for improving the transmission reliability of the PUCCH.

According to some embodiments of the present application, in step 21, the network side device may configure the PUCCH resource for the terminal according to the beam capability information and the uplink channel state of the terminal. Before this, the network side device may receive beam capability information transmitted by a terminal, where the beam capability information is used to indicate the number of transmission beams supported by the terminal.

Herein, when the terminal supports the transmission capability of only one beam, it is assumed that a first transmission beam is one transmission beam supported by the terminal; when the terminal supports transmission capabilities of at least two beams, it is assumed that the first and second transmission beams are two transmission beams supported by the terminal.

Specifically, the network side device may perform the above steps 21 to 22 when at least one of the following conditions is satisfied, and configure the PUCCH resource and spatial relationship for the terminal:

1) the terminal supports transmission capabilities of at least two beams.

When the terminal supports at least two transmission beams, the PUCCH resource including two parts according to the embodiment of the present application may be configured, so that two partial resources with different transmission beams of the terminal may be subsequently used to transmit two partial resources with different time and frequency positions, respectively, to improve spatial diversity gain, time diversity gain, and frequency diversity gain, and improve PUCCH transmission performance. Note that the beam capability of the terminal described herein is for the transmission beam of the terminal.

2) And the time selective fading, the space selective fading or the frequency selective fading of the uplink channel indicated by the uplink channel state information exceeds a corresponding preset threshold.

When the uplink channel state condition of the terminal is poor, the PUCCH resource including two parts according to the embodiment of the present application may also be configured, so that two part resources with incompletely identical time domain and frequency domain positions may be subsequently utilized, thereby improving the time diversity gain and the frequency diversity gain of PUCCH transmission, and improving the PUCCH transmission performance.

In addition, the obtaining of the uplink channel state information may be that the network side device receives the uplink channel state information reported by the terminal, and/or the network side device obtains the uplink channel state information by measuring the relevant reference signal. The uplink channel state information may specifically include, but is not limited to, one or more of the following parameters: signal-to-noise ratio, Rank Indicator (RI), Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and the like.

Two specific PUCCH resource configuration manners in step 21 are provided below, when the first partial resource and the second partial resource at least partially overlap in the time domain:

PUCCH resource configuration mode one (based on higher layer signaling):

and sending frequency hopping configuration information of the PUCCH resources to the terminal through high-level signaling, wherein the frequency hopping configuration information comprises a frequency domain starting position of a first part of resources, frequency hopping indication information used for indicating frequency hopping in a closed time slot, and a frequency domain starting position of a second part of resources.

Here, the PUCCH resources may be configured through RRC signaling, and relevant parameters in the RRC signaling are shown in table 1, where the starting PRB is used to indicate a starting PRB of the second partial resource of the configured PUCCH resource; the intra-slot frequency hopping function of the PUCCH is configured to be off, and at this time, the second hop PRB (sencondhopprb) is used to indicate a start PRB of the second part of the configured PUCCH resource.

TABLE 1

PUCCH resource configuration scheme two (based on physical layer commands):

Here, frequency domain offset (amount offset) information may be added to the downlink control information DCI 1-0/1-1, and is based on a PRB offset of the first partial resource of the PUCCH resource, that is, a starting PRB of the first partial resource, and is a difference value with respect to the base value or an index of the difference value. In addition, the difference index table may be configured semi-statically in advance through higher layer signaling.

Thus, after configuring the PUCCH resources and the spatial relationship in

steps

21 and 22, the network side device in this embodiment may further send transmission scheduling information to the terminal, where the transmission scheduling information is used to schedule the terminal to send the same uplink control information or different portions of the same uplink control information on the first partial resource and the second partial resource of the same PUCCH resource, respectively, based on the PUCCH resources and the activated spatial relationship. Furthermore, the network side device may further detect, according to the PUCCH resources configured by the terminal and the activated spatial relationship, uplink control information respectively sent by the terminal on the first part of resources and the second part of resources of the same PUCCH resource, and combine the uplink control information detected on the first part of resources and the second part of resources.

Fig. 4 is a diagram illustrating an example of interaction between a network-side device and a terminal according to the method in the embodiment of the present application. In this example:

and step 41, the terminal reports the beam capability information.

And step 42, the network side equipment configures the PUCCH resource for the terminal according to the beam capability information and the uplink channel state of the terminal. In addition, the network side device in the embodiment of the present application may also default that the terminal has only a single capability of sending a beam when the beam capability information reported by the terminal is not received.

Step 43, the network side device activates at least one spatial relationship of the PUCCH.

Step 44, the network side device schedules the terminal to respectively send the same uplink control information or different parts of the same uplink control information on the first part resource and the second part resource of the same PUCCH resource based on the space relation between the PUCCH resource and the activated PUCCH resource

Step 45, the terminal sends the same uplink control information or sends different parts of the same uplink control information on the first part of resources and the second part of resources of the same PUCCH resources respectively according to the transmission scheduling information; and the network side equipment detects the uplink control information respectively sent by the terminal on the first part of resources and the second part of resources of the same PUCCH resource, and combines the uplink control information detected on the first part of resources and the second part of resources.

Several examples of transmission scheduling information of embodiments of the present application are provided below to enable transmission of different portions of PUCCH resources based on different transmit beams and spatial relationships.

A) The first part of resources and the second part of resources are at least partially overlapped in time domain

This case a corresponds to the PUCCH resource shown by the dotted

box

31 or 32 in fig. 3. At this time, according to the transmission beam capability of the terminal and the active spatial relationship, there may be the following different scheduling manners:

scheduling mode 1:

in a case that the terminal supports transmission capability of only one beam and the activation command activates only one spatial relationship, the transmission scheduling information is specifically configured to: and scheduling the terminal to transmit first uplink control information on the first part of resources based on the first transmission beam and the activated spatial relationship, and to transmit second uplink control information on the second part of resources based on the first transmission beam and the activated spatial relationship. Here, the first uplink control information and the second uplink control information transmitted on the same PUCCH resource may be the same uplink control information or different portions of the same uplink control information.

In the scheduling mode 1, the terminal uses 1 transmission beam and 1 spatial relationship to transmit different parts of the PUCCH resource, which is equivalent to the terminal side transmitting using 1 transmission beam and the network side device receiving using 1 reception beam. When two parts of the PUCCH resource both transmit the same uplink control information, the scheduling method 1 may obtain a gain of repeated transmission and a gain of frequency diversity. When two parts of the PUCCH resource transmit different parts of the same uplink control information, the scheduling method 1 can obtain a gain of frequency diversity.

Scheduling mode 2:

in a case that the terminal supports transmission capabilities of at least two beams and the activation command activates only one spatial relationship, the transmission scheduling information is specifically configured to: and scheduling the terminal to transmit first uplink control information on the first part of resources based on the first transmission beam and the activated spatial relationship, and to transmit second uplink control information on the second part of resources based on the second transmission beam and the activated spatial relationship. Here, the first uplink control information and the second uplink control information transmitted on the same PUCCH resource may be the same uplink control information or different portions of the same uplink control information.

In the scheduling mode 2, the terminal uses 2 transmission beams and 1 spatial relationship to transmit different parts of the PUCCH resource, which is equivalent to that the terminal side uses 2 transmission beams to transmit, and the network side device uses 1 reception beam to receive. When both parts of the PUCCH resource transmit the same uplink control information, the scheduling method 2 may obtain a gain of repeated transmission, a gain of spatial diversity, and a gain of frequency diversity. When two parts of the PUCCH resource respectively transmit different parts of the same uplink control information, the scheduling method 2 may obtain gains of spatial diversity and frequency diversity.

Scheduling mode 3:

in a case that the terminal supports transmission capabilities of at least two beams and the activation command activates the first spatial relationship and the second spatial relationship, the transmission scheduling information is specifically configured to: and scheduling the terminal to transmit first uplink control information on the first part of resources based on the first transmission beam and the first spatial relationship, and transmitting second uplink control information on the second part of resources based on the second transmission beam and the second spatial relationship. Here, the first uplink control information and the second uplink control information transmitted on the same PUCCH resource are the same uplink control information or different portions of the same uplink control information.

In the scheduling mode 3, the terminal uses 2 transmission beams and 2 spatial relationships to transmit different parts of the PUCCH resource, which is equivalent to the terminal side transmitting using 2 transmission beams and the network side device receiving using 2 reception beams. When both parts of the PUCCH resource transmit the same uplink control information, the scheduling method 3 can obtain a gain of repeated transmission, a gain of spatial diversity, and a gain of frequency diversity. When two parts of the PUCCH resource respectively transmit different parts of the same uplink control information, the scheduling method 3 may obtain gains of spatial diversity and frequency diversity.

B) The first part of resources and the second part of resources do not have overlapping parts in time domain

This case B corresponds to the PUCCH resource indicated by the dotted box 33 in fig. 3. At this time, according to the transmission beam capability of the terminal and the active spatial relationship, there may be the following different scheduling manners:

scheduling mode 4:

in a case that the terminal supports transmission capability of only one beam and the activation command activates only one spatial relationship, the transmission scheduling information is specifically configured to: and scheduling the terminal to transmit third uplink control information on the first part of resources based on the first transmission beam and the activated spatial relationship, and to transmit fourth uplink control information on the second part of resources based on the first transmission beam and the activated spatial relationship, where the third uplink control information and the fourth uplink control information are the same uplink control information.

In the scheduling mode 4, the terminal transmits different parts of the PUCCH resource by using 1 transmit beam and 1 spatial relationship, which is equivalent to the terminal side transmitting by using 1 transmit beam and the network side device receiving by using 1 receive beam. The scheduling scheme 4 can obtain the gain of the repeated transmission, the gain of the time diversity and the gain of the frequency diversity.

Scheduling mode 5:

in a case that the terminal supports transmission capabilities of at least two beams and the activation command activates only one spatial relationship, the transmission scheduling information is specifically configured to: and scheduling the terminal to transmit third uplink control information on the first part of resources based on the first transmission beam and the activated spatial relationship, and to transmit fourth uplink control information on the second part of resources based on the second transmission beam and the activated spatial relationship, where the third uplink control information and the fourth uplink control information are the same uplink control information.

In the scheduling mode 5, the terminal transmits different parts of the PUCCH resource by using 2 transmit beams and 1 spatial relationship, which is equivalent to the terminal side transmitting by using 2 transmit beams and the network side device receiving by using 1 receive beam. The scheduling mode 5 can obtain the gains of repeated transmission, time diversity, spatial diversity and frequency diversity.

Scheduling mode 6:

in a case that the terminal supports transmission capability of only one beam, and the activation command activates the first spatial relationship and the second spatial relationship, the transmission scheduling information is specifically used for: scheduling the terminal to transmit fifth uplink control information on the first part of resources based on the first transmission beam and a first spatial relationship, and to transmit sixth uplink control information on the second part of resources based on the first transmission beam and a second spatial relationship; here, the fifth uplink control information and the sixth uplink control information are the same uplink control information or different parts of the same uplink control information.

In the scheduling mode 6, the terminal transmits different parts of the PUCCH resource by using 1 transmit beam and 2 spatial relationships, which is equivalent to the terminal side transmitting by using 1 transmit beam and the network side device receiving by using 2 receive beams. When both parts of the PUCCH resource transmit the same uplink control information, the scheduling means 6 may obtain the gain of the repeated transmission, the time diversity, the space diversity, and the frequency diversity. When two parts of the PUCCH resource respectively transmit different parts of the same uplink control information, the scheduling method 6 may obtain gains of time diversity, space diversity, and frequency diversity.

Scheduling mode 7:

in a case that the terminal supports transmission capabilities of at least two beams and the activation command activates the first spatial relationship and the second spatial relationship, the transmission scheduling information is specifically configured to: scheduling the terminal to transmit fifth uplink control information on the first part of resources based on the first transmission beam and the first spatial relationship, and to transmit sixth uplink control information on the second part of resources based on the second transmission beam and the second spatial relationship; here, the fifth uplink control information and the sixth uplink control information are the same uplink control information or different parts of the same uplink control information.

In the scheduling mode 7, the terminal transmits different parts of the PUCCH resource by using 2 transmit beams and 2 spatial relationships, which is equivalent to the terminal side transmitting by using 2 transmit beams and the network side device receiving by using 2 receive beams. When both parts of the PUCCH resource transmit the same uplink control information, the scheduling means 7 may obtain the gain of the repeated transmission, the time diversity, the space diversity, and the frequency diversity. When two parts of the PUCCH resource respectively transmit different parts of the same uplink control information, the scheduling method 7 may obtain gains of time diversity, space diversity, and frequency diversity.

In addition, for the scheduling manner 6 and the scheduling manner 7, when the fifth uplink control information and the sixth uplink control information are different parts of the same uplink control information, the method for transmitting transmission scheduling information to a terminal by a network side device may specifically include:

Table 2 gives an example of a specific implementation of the spatial relationship switching command described above. And changing the spatial relationship corresponding to each part of the PUCCH resources in the time slot or the subslot (subslot) by switching on or off the frequency hopping spatial relationship switching enabling mark.

TABLE 2

For example, for a first PUCCH resource, a scheduling terminal sends a first part of resources of the first PUCCH resource in a certain slot by using a first correspondence, and sends a second part of resources of the first PUCCH resource by using a second correspondence; and for a second PUCCH resource in the same slot, the terminal may be scheduled to transmit a first part of resources of the second PUCCH resource by using a second correspondence, and transmit a second part of resources of the second PUCCH resource by using a first correspondence. Through the above manner, the embodiment of the application can further improve the gain of frequency diversity, reduce the adverse effect of frequency selective fading, and improve the transmission reliability of the PUCCH.

In addition, in this embodiment of the present application, when sending transmission scheduling information to a terminal, the network side device may further carry transmission mode indication information in the transmission scheduling information, where the transmission mode indication information is used to indicate: the same uplink control information is repeatedly transmitted in different parts of the same PUCCH resource, or different parts of the same uplink control information are transmitted in different parts of the same PUCCH resource.

Referring to fig. 5, a method for configuring PUCCH resources according to an embodiment of the present application, when applied to a terminal side, includes:

step 51, receiving configuration information of a PUCCH resource sent by a network side device, where the PUCCH resource includes a first part of resource and a second part of resource, the first part of resource and the second part of resource are used to carry the same uplink control information or different parts of the same uplink control information, and the first part of resource and the second part of resource are both continuous frequency domain resources and do not have an overlapping portion in a frequency domain.

Here, the first part of resources and the second part of resources at least partially overlap in a time domain, or there is no overlapping portion of the first part of resources and the second part of resources in the time domain.

Step 51, receiving an activation command of the spatial relationship of the PUCCH resources sent by the network side device, activating the spatial relationship of the PUCCH resources, so that the first part of resources and the second part of resources correspond to different spatial relationships, respectively, or the first part of resources and the second part of resources correspond to the same spatial relationship.

Through the steps, the method and the device can realize flexible configuration of PUCCH resources and spatial relations, thereby providing support for improving the transmission reliability of the PUCCH.

According to some embodiments of the present application, before step 51, the terminal may further send beam capability information of the terminal to the network side device, so as to configure the PUCCH resource as reference information at the network side device.

In step 51, when the first partial resource and the second partial resource at least partially overlap in the time domain, the terminal may receive, in accordance with the first PUCCH resource configuration method, frequency hopping configuration information of the PUCCH resource sent by the network side device through a higher layer signaling, where the frequency hopping configuration information includes a frequency domain start position of the first partial resource, frequency hopping indication information for indicating that frequency hopping in the timeslot is turned off, and a frequency domain start position of the second partial resource; corresponding to the foregoing second configuration mode of the PUCCH resource, the terminal may receive the frequency domain position of the first part of the resource and the indication information of the frequency domain offset of the second part of the resource with respect to the first part of the resource, which are sent by the network side device through physical layer signaling, so as to obtain the specific frequency domain position of the PUCCH resource.

After the step 52, the terminal may further receive transmission scheduling information sent by the network side device, where the transmission scheduling information is used to schedule the terminal to send the same uplink control information or different parts of the same uplink control information on the first part of resources and the second part of resources of the same PUCCH resource based on the spatial relationship between the PUCCH resource and the active PUCCH resource; and then respectively sending the same uplink control information or sending different parts of the same uplink control information on the first part of resources and the second part of resources of the same PUCCH resources according to the transmission scheduling information.

For the above specific example of transmitting the scheduling information, reference may be made to the description of the network side device part, and details are not repeated here for brevity.

In addition, corresponding to the foregoing scheduling manner 6 and scheduling manner 7, when the fifth uplink control information and the sixth uplink control information are different parts of the same uplink control information, and the terminal receives transmission scheduling information sent by the network side device, the method specifically includes:

Further, when the terminal sends different parts of the same uplink control information on the first part of resources and the second part of resources of the same PUCCH resource according to the transmission scheduling information, the terminal may repeat transmission of a spatial relationship pattern and a spatial relationship switching command according to the time domain, send the fifth uplink control information on the first PUCCH resource by using the first corresponding relationship, and send the sixth uplink control information by using the second corresponding relationship, respectively; and on a second PUCCH resource, the fifth uplink control information is sent by adopting the second corresponding relation, and the sixth uplink control information is sent by adopting the first corresponding relation.

In addition, in this embodiment of the present application, the terminal may further obtain, from the transmission scheduling information, transmission mode indication information when receiving the transmission scheduling information sent by the network side device, where the transmission mode indication information is used to indicate: the same uplink control information is repeatedly transmitted in different parts of the same PUCCH resource, or different parts of the same uplink control information are transmitted in different parts of the same PUCCH resource. And determining the transmission content of the first part of resources and the second part of resources of the same PUCCH resources according to the transmission mode indication information.

Through the above manner, the embodiment of the application can realize flexible configuration of PUCCH resources and spatial relationship, and further improve the reliability of PUCCH transmission based on the configuration.
