Technical field

The present application relates to the field of communication technologies, and in particular, to a method and a device for multiplexing channel state information and a hybrid automatic retransmission request confirmation.

Background technique

In the future fifth-generation mobile communication technology (5th-Generation, 5G), system capacity, instantaneous peak rate, spectrum efficiency, cell-edge user throughput, and delay have many higher requirements. Hybrid automatic repeat request (HARQ) -acknowledgement (ACK) of channel state information (channel state information, downlink control information, downlink control information, DCI) and transmission (block) Reusing time-frequency resources can improve spectral efficiency to a certain extent. Specifically, DCI is a dynamic signaling that a transmitting and receiving point (English: transmission point, TRP) sends to a user equipment (UE) in real time through a physical downlink control channel (PDCCH). The DCI then encapsulates the CSI and the HARQ-ACK of the DCI's TB in uplink control information (uplink control information) (UCI) and sends them to the TRP through the uplink physical control channel (PUCCH) resource. The selection process of PUCCHresource in this process is as follows:

1. The TRP configures multiple PUCCH resource sets (resource sets) for the UE through PUCCH configuration. Each PUCCH resource set contains multiple PUCCH resources. As shown in Figure 1, resource set 1 contains 8 to 32. Resource PUCCH resources, resource set 2 includes 8 PUCCH resources, resource set 3 includes 8 PUCCH resources, and resource set 4 includes 8 PUCCH resources.

2. The TRP sends a DCI to the UE. The DCI includes a PUCCH resource indicator field. The PUCCH resource indicator field is used to indicate which PUCCH resource in the PUCCH resource set feeds back UCI.

3. The UE selects a PUCCH resource set from the multiple PUCCH resource sets described above according to the number of UCI bits to be sent, and uses the PUCCH resource indicated by the PUCCH resource indicator on the PUCCH resource set. Send UCI to TRP.

4. The TRP estimates the resource set used by the UE to send UCI according to the expected number of UCI bits, and then detects the UCI on the PUCCH resource specified by the PUCCH resource indicator field on the estimated resource set.

In 5G, a Multi-TRP scenario is proposed. In the Multi-TRP scenario, multiple TRPs cooperate and communicate. Therefore, multiple TRPs may each independently send DCI to the UE. In this case, how the UE generates HARQ-ACK for TB transmission in DCI is a technical problem that needs to be solved by those skilled in the art.

Related parameters are used to obtain CORESET time-frequency resources. The search space may be referred to as a search space configuration parameter, that is, a parameter related to signaling configuration, used to obtain when and in what manner a candidate or possible PDCCH is searched; the search space may also directly refer to a place where a candidate PDCCH is detected, Or where testing is needed.

The downlink control information configuration information may also be a downlink control channel configuration parameter group (Physical Downlink Control Channel Config group, PDCCH-Config group), a control resource set configuration parameter group (CORESET group), or a search space configuration parameter group (search space configuration group). ).

For example, when the downlink control parameter is a parameter related to the parameter in the downlink control information, the parameter in the downlink control information may be an antenna port or an antenna port index number, and may be a demodulation parameter signal (Demodulation Reference Signal, DMRS) port parameters. The DMRS port parameter may be a DMRS port, a DMRS port index number, a DMRS port identification code, a DMRS port group index number, or a DMRS port group identification code.

Among them, the relationship between the antenna port index number, the DMRS port, and the antenna port can be: the terminal device can obtain the DMRS port based on the antenna port index number, and then can use the DMRS port to obtain the antenna port. For example, antenna port = 1000 + DMRS port in the downlink system; antenna port = DMRS port in the uplink system. Among them, whether it is uplink or downlink, the DCI indicates the antenna port or antenna port index number. Optionally, the terminal device may also obtain a DMRS port index number, a DMRS port identification code, a DMRS port group, a DMRS port group index number, or a DMRS port group identification code based on the antenna port or antenna port index number.

The downlink control information configuration information and downlink control parameters are exemplified below for easy understanding:

In a first example, the downlink control information configuration information includes a first identifier of a configuration of a PDCCH for carrying a first DCI.

Specifically, the DCI is carried on the PDCCH. Before sending the DCI to the terminal on the network side (for example, the first network device, the second network device, etc.), it is necessary to send the terminal a PDCCH configuration (PDCCH-Config) associated with the DCI. In order to obtain the PDCCH carrying the DCI according to the PDCCH-Config, the terminal detects the DCI on the PDCCH. Among them, different PDCCHConfigs have different configuration identifiers, and two methods are listed below for illustration.

(1) Assuming that the configuration identifier of the PDCCH-Config associated with the first DCI sent by the first network device to the terminal is PDCCH-Config-ID = 0, and the PDCCH-Config associated with the second DCI sent by the second network device to the terminal Configuration ID is PDCCH-Config-ID = 1, then there is, the first DCI is carried on the PDCCH specified by PDCCH-Config identified by PDCCH-Config-ID = 0, and the second DCI is carried on PDCCH-Config-ID = 1 on the PDCCH specified by the PDCCH-Config identified. In this case, the first identifier in the embodiment of the present application may be PDCCH-Config-ID = 0.

(2) It is assumed that the configuration identifier of the PDCCH-Config associated with the first DCI sent by the first network device to the terminal is PDCCH-Config0, and the configuration identifier of the PDCCH-Config associated with the second DCI sent by the second network device to the terminal is PDCCH-Config1, then the first DCI is carried on the PDCCH specified by PDCCH-Config identified by PDCCH-Config0, and the second DCI is carried on the PDCCH specified by PDCCH-Config identified by PDCCH-Config1. In this case, the first identifier in the embodiment of the present application may be PDCCH-Config0.

In a second example, the downlink control information configuration information includes a second identifier of a CORESET group for carrying the first DCI.

Specifically, one or more control resource sets (controlResourceSet, CORESET) may form a CORESET group (CORESET group), and the terminal may detect the first DCI and the second DCI respectively in two different CORESET groups. The two different CORESET groups are part of multiple CORESET groups configured for the terminal in advance. The configuration of these multiple CORESET groups (using two groups as an example) can be configured as follows:

The network side (for example, the first network device, the second network device, etc.) sends a PDCCH-Config to the terminal. The PDCCH-Config indicates two CORESET groups, so subsequent terminals can blindly detect a maximum of one on each of the two CORESET groups. DCI. These two CORESET groups have at least the following two indication methods:

(1) Add two CORESET group indexes in PDCCH-Config. Each CORESET group index can consist of one character or one character string. For example, one CORESET group index is CORESET group id = 0, and the other CORESET group index is CORESET group id = 1. A CORESET group can be uniquely determined according to any CORESET group index. In addition, each CORESET in the CORESET group adds a CORESET group id to mark the CORESET group to which the CORESET belongs.

(2) Add two CORESET group sequences in PDCCH-Config. The CORESET group index may consist of one character or one character string. For example, one CORESET group sequence is CORESET group_0, and the other CORESET group sequence is CORESET group_1. A CORESET group sequence may be composed of some CORESET identifiers. The CORESET group composed of these CORESET groups is a CORESET group uniquely identified by the one CORESET group sequence.

The index or sequence of the above CORESET group can be used as the second identifier for easy description, for example:

For the above manner (1), if the first DCI is on a CORESET group whose CORESET group sequence is CORESET group id = 0, the second identifier may be CORESET group id = 0.

For the above manner (2), if the first DCI is on a CORESET group whose CORESET group sequence is CORESET group_0, the second identifier may be CORESET group_0.

In the third example, the downlink control information configuration information includes a third identifier of a search space SS group for carrying the first DCI.

Specifically, the terminal detects the first DCI and the second DCI in two different search spaces (SS), and the two SSs belong to different SS groups (search space), so the above The first DCI and the second DCI can be regarded as being respectively detected on two different SS groups. Each SS group has its own SS group identifier. On which SS group the first DCI is located, the SS group identifier of the SS group is the third identifier. Here are two ways to illustrate:

(1) The first DCI is carried on the SS group identified by SS group-ID = 0, and the second DCI is carried on the SS group identified by SS group-ID = 1. In this case, the first identifier in the embodiment of the present application may be SS group-ID = 0.

(2) The first DCI is carried on the SS group identified by SS group_0, and the second DCI is carried on the SS group identified by SS group_1. In this case, the first identifier in the embodiment of the present application may be SS group_0.

In addition, when the SS group ID of the SS group in each CORESET is independently divided, the CSI report configuration information (CSI-ReportConfig) also needs to add the CORESET group ID of the CORESET to which the SS group carrying the first DCI belongs, so that the terminal can The CORESET group identifier and the third identifier uniquely determine the SS group where the first DCI is located. When the SS group identifiers of all SS groups in CORESET are jointly divided, the CSI report configuration information (CSI-ReportConfig) does not need to include CORESET. Group ID.

In the fourth example, the downlink control parameter is a fourth identifier of a DMRS group to which the DMRS port included in the first DCI belongs.

Specifically, the first network device and the second network device each use a demodulation reference signal (DMRS) group, and each group includes a number of DMRS port numbers, and the DMRS ports in the same group are quasi co-located (quasi co-location (QCL). Each DMRS group has its own identifier. In the embodiment of the present application, the DMRS group identifier of the DMRS group to which the DMRS port number included in the first DCI belongs is referred to as the fourth identifier for the convenience of subsequent description.

In a fifth example, the downlink control parameter is a sixth identifier configured with a bandwith part (BWP).

Specifically, the network side sends multiple BWP configurations to the terminal, and each BWP configuration has an identifier. In the embodiment of the present application, the identifier of the BWP configuration where the PDCCH configuration information associated with the first DCI is referred to as a sixth identifier is convenient for subsequent description. For example, the sixth identifier may be expressed as BWP ID = 0, or BWP_0, and so on.

Example 6. The downlink control information configuration information includes a seventh identifier or an eighth identifier for carrying the CORESET of the first DCI, and the eighth identifier is a scrambling code on the CORESET.

Specifically, the terminal detects the first DCI and the second DCI respectively at two different CORESETs. The two different CORESETs are part of configuring multiple CORESETs for the terminal in advance. The configuration methods of these multiple CORESETs (the two are described as examples) can be as follows:

The network side (for example, the first network device, the second network device, etc.) sends the PDCCH-Config to the terminal, and the PDCCH-Config indicates two CORESETs. These two CORESET indication methods exist in at least the following two ways:

(1) Add two CORESET indexes or identifiers in PDCCH-Config. Each CORESET index or identifier can consist of a character or a character string. For example, one CORESET index is CORESET id = 0 and the other CORESET index is CORESET. id = 1. A CORESET can be uniquely determined according to any CORESET index.

(2) Add two CORESET indexes or identifiers in the PDCCH-Config. The CORESET index may consist of a character or a character string. For example, one CORESET index is CORESET group_0, and the other CORESET index is CORESET group_1.

In addition, in (1) and (2), a CORESET ID is added to the CORESET in each CORESET group to mark the CORESET group to which the CORESET belongs. When there is only one CORESET in a CORESET group, the index of the CORESET can be regarded as the index of the CORESET group, or the index of the CORESET group can also be regarded as the index of the CORESET in the group.

The above CORESET index or sequence or logo can be used as the seventh logo for easy description, for example:

For the above manner (1), if the first DCI is on a CORESET whose CORESET index is CORESET id = 0, the seventh identifier may be CORESET id = 0.

For the above manner (2), if the first DCI is on a CORESET with the CORESET index being CORESET id = 0, the seventh identifier may be CORESET id_0.

In addition, one CORESET corresponds to one scrambling code, so the downlink control information configuration information includes an eighth identifier, and the eighth identifier is a scrambling code on CORESET; the first DCI is on the CORESET identified by the eighth identifier. Bearer DCI.

Step S705: The terminal receives the CSI report configuration information sent by the first network device.

Optionally, if the CSI report configuration information is sent by another network device, the terminal receives the CSI report configuration information sent by other network devices.

Step S706: The terminal generates a first UCI according to the CSI report configuration information.

Specifically, the terminal may obtain “downlink control information configuration information or downlink control parameters” according to the CSI report configuration information, and further determine the first DCI according to the “downlink control information configuration information or downlink control parameters”. Since the first DCI is determined according to the "downlink control information configuration information or downlink control parameters" in the CSI report configuration information, the first UCI is then generated based on the first CSI and the HARQ-ACK for the TB of the first DCI, That is, the first UCI includes the HARQ-ACK of the first CSI and the TB for the first DCI. In addition, for different situations, there are differences in the processes performed by the terminal in generating the first UCI, which are described below by way of example.

For the above example 1, the terminal generating the first UCI according to the CSI report configuration information may specifically include: the terminal determining the PDCCH configuration identified by the first identifier; and the terminal determining the PDCCH configuration identified by the first identifier The identified configuration receives the first DCI; the terminal generates a first UCI according to the first CSI and a HARQ-ACK for a TB of the first DCI.

For the above second example, the terminal generating the first UCI according to the CSI report configuration information may specifically include: the terminal determining the CORESET group identified by the second identifier; and the terminal determining The first DCI sent on the identified CORESET group; the terminal generates a first UCI according to the first CSI and a HARQ-ACK for a TB of the first DCI.

For the third example described above, the terminal generating the first UCI according to the CSI report configuration information may specifically include: the terminal determining an SS group identified by the third identifier; and the terminal determining the identifier identified by the third identifier The first DCI sent on the SS group of the UE; the terminal generates a first UCI according to the first CSI and the HARQ-ACK for the TB of the first DCI.

For the above fourth example, the terminal generating the first UCI according to the CSI report configuration information may specifically include: the terminal determining a DMRS group identified by the fourth identifier; and the terminal determining that the DMRS included in the terminal belongs to the first Four identifies the first DCI of the DMRS group identified; the terminal generates a first UCI according to the first CSI and HARQ-ACK for the TB of the first DCI.

For the above fifth example, the terminal generating the first UCI according to the CSI report configuration information may specifically include: determining a BWP configuration identified by a sixth identifier, and then determining PDCCH configuration information included in the BWP configuration, and then determining the PDCCH configuration The DCI carried on the information-configured PDCCH is the above-mentioned first DCI, and the terminal generates a first UCI according to the first CSI and the HARQ-ACK for the TB of the first DCI.

For the above example 6, the terminal generating the first UCI according to the CSI report configuration information may specifically include: the terminal determines the CORESET identified by the seventh identifier; and the terminal determines the identifier identified by the seventh identifier The first DCI sent on CORESET; the terminal generates a first UCI according to the first CSI and a HARQ-ACK for a TB of the first DCI. Or, the terminal determines the CORESET identified by the eighth identifier; the terminal determines the first DCI sent on the CORESET identified by the eighth identifier; and the terminal determines the first DCI based on the first CSI and the The HARQ-ACK of the TB of the first DCI generates a first UCI. The eighth identifier is a scrambling code of CORESET.

Step S707: The terminal generates a second UCI.

Specifically, the second network device does not send information similar to the CSI report configuration information like the first network device to indicate that there is an association relationship between the second DCI and the first CSI. Therefore, the second UCI includes information for the second DCI. HARQ-ACK of a TB, but does not include the above-mentioned first CSI.

Step S708: The terminal sends a first UCI to the first network device.

Specifically, the terminal determines which PUCCH resource set to use to send the first UCI according to the number of bits of the first UCI, and the determined PUCCH resource set may be referred to as a first PUCCH resource set to facilitate subsequent description. In addition, the terminal also determines which PUCCH resource in the first PUCCH resource set sends the first UCI according to the PUCCH resource indicator field included in the first DCI. The determined PUCCH resource can be referred to as the first PUCCH resource to facilitate subsequent follow-up. description. After that, the terminal sends the first UCI on the first PUCCH resource on the first PUCCH resource set.

Step S709: The terminal sends a second UCI to the second network device.

Specifically, the terminal may also determine which PUCCH resource set to use to send the second UCI according to the bit number of the second UCI, and the determined PUCCH resource set may be referred to as a second PUCCH resource set to facilitate subsequent description. In addition, the terminal may also determine which PUCCH resource in the second PUCCH resource set sends the second UCI according to the PUCCH resource indicator field included in the second DCI, and the determined PUCCH resource may be referred to as the second PUCCH resource for convenience Subsequent description. After that, the terminal sends the second UCI on the second PUCCH resource on the second PUCCH resource set.

Step S710: The first network device receives the first UCI sent by the terminal.

Specifically, because the first network device has sent the CSI report configuration information to the terminal, the first network device knows that the UCI fed back by the terminal will include the first CSI and the HARQ-ACK for the first DCI TB, so the first network device The number of bits of the first UCI can be reasonably estimated, so that based on the number of bits of the first UCI, it is determined that the terminal will send the first UCI on the first PUCCH resource set; in addition, because the first PUCCH resource is passed by the first network device The PUCCH resource indicator field of the first DCI indicates to the terminal, so the first network device knows that the terminal will send the first UCI on the first PUCCH resource. Therefore, the first network device will eventually receive (or detect) the first UCI on the first PUCCH resource on the first PUCCH resource set.

Step S711: The second network device receives the second UCI sent by the terminal.

Specifically, since the second network device has not sent the CSI report configuration information to the terminal, the second network device knows that the UCI fed back by the terminal will include the HARQ-ACK for the TB of the second DCI but does not include the first CSI. The two network devices can reasonably estimate the number of bits of the second UCI, so that based on the number of bits of the second UCI, it is determined that the terminal will send the second UCI on the second PUCCH resource set; in addition, since the second PUCCH resource is determined by the second The network device indicates to the terminal through the PUCCH resource indicator field of the second DCI, so the second network device knows that the terminal will send the second UCI on the second PUCCH resource. Therefore, the second network device will eventually receive (or detect) the second UCI on the second PUCCH resource on the second PUCCH resource set.

In the method described in FIG. 7, the terminal determines that the first CSI is associated with the first DCI according to the CSI report configuration information. Afterwards, when the terminal needs to feed back to the network the HARQ-ACK for the TB of the first DCI and the HARQ-ACK for the TB of the other DCI, the terminal encapsulates the first CSI and the HARQ-ACK of the TB for the first DCI in the same package. One UCI is not encapsulated in the same UCI as the HARQ-ACK for the TB for the second DCI. In addition, the first network device can also predict that the UCI sent to the first network device includes the first CSI according to the CSI report configuration information, so the first network device can reasonably estimate the size of the UCI sent to the first network device, so that Receive the UCI on the correct PUCCH resource set and PUCCH resource. Correspondingly, the second network device can also know that there is no association between the first CSI and the second DCI, so the second network device can predict that the UCI sent to the second network device does not include the first CSI, so the second network device can reasonably The size of the UCI for the second DCI is estimated, so that the UCI is received on the correct PUCCH resource set and PUCCH resource.

Please refer to FIG. 8. FIG. 8 is a channel state information and hybrid automatic retransmission request confirmation multiplexing method provided in an embodiment of the present application. The method may be implemented based on the communication system shown in FIG. Limited to the following steps:

Step S801: The first network device sends a third DCI to the terminal.

Specifically, the DCI sent by the first network device to the terminal is referred to as a third DCI to facilitate subsequent description. The third DCI includes a transmission configuration indication (TCI), where the TCI includes a fifth identifier, and the fifth identifier is used to identify a reference signal port (RSport).

Step S802: The second network device sends a fourth DCI to the terminal.

Specifically, the DCI sent by the second network device to the terminal is referred to as a fourth DCI to facilitate subsequent description. Optionally, the reporting slot of the HARQ-ACK of the TB of the third DCI is the same as the reporting slot of the HARQ-ACK of the TB of the fourth DCI, which is equivalent to the HARQ-ACK of the third DCI and the HARQ- of the fourth DCI. ACK is sent to the network side at the same time. Of course, the reporting slot of the HARQ-ACK of the TB of the third DCI may be different from the reporting slot of the HARQ-ACK of the TB of the fourth DCI.

Step S803: The terminal receives the third DCI and the fourth DCI.

Step S804: The terminal generates a third UCI.

Specifically, the terminal first parses the TCI in the third DCI, and then determines the reference signal port identified by the fifth identifier according to the fifth identifier in the TCI, and then determines the fifth identifier to determine the reference signal identified by the fifth identifier. The DMRS group corresponding to the port. The DMRS group determined here can be referred to as the DMRS group corresponding to the third DCI; the DMRS group corresponding to the fourth DCI can be determined according to the same principle; RS Which port is the DMRS group with quasi co-location (QCL) relationship. If the determined DMRS group is the DMRS group corresponding to the third DCI group, then the terminal according to the second CSI and the third DCI The HARQ-ACK of the TB in the eNB generates a third UCI, where the third UCI includes the second CSI and the HARQ-ACK for the TB of the third DCI.

Step S805: The terminal generates a fourth UCI.

Specifically, the fourth UCI includes HARQ-ACK for the TB of the fourth DCI, but does not include the second CSI.

Step S806: The terminal sends a third UCI to the first network device.

Specifically, the terminal determines which PUCCH resource set to use to send the third UCI according to the number of bits of the third UCI, and the determined PUCCH resource set may be referred to as a first PUCCH resource set to facilitate subsequent description. In addition, the terminal also determines which PUCCH resource in the first PUCCH resource set sends the third UCI according to the PUCCH resource indicator field included in the third DCI. The determined PUCCH resource can be called the first PUCCH resource to facilitate subsequent description. After that, the terminal sends the third UCI on the first PUCCH resource on the first PUCCH resource set.

Step S807: The terminal sends a fourth UCI to the second network device.

Specifically, the terminal may also determine which PUCCH resource set to use to send the fourth UCI according to the bit number of the fourth UCI, and the determined PUCCH resource set may be referred to as a second PUCCH resource set to facilitate subsequent description. In addition, the terminal can also determine which PUCCH resource in the second PUCCH resource set sends the fourth UCI according to the PUCCH resource indicator field included in the fourth DCI, and the determined PUCCH resource can be called the second PUCCH resource for convenience Subsequent description. After that, the terminal sends the fourth UCI on the second PUCCH resource on the second PUCCH resource set.

Step S808: The first network device receives the third UCI sent by the terminal.

Specifically, because the first network device adds a fifth identifier to the TCI in the third DCI, the first network device knows that the UCI fed back by the terminal will include the HARQ-ACK of the second CSI and the TB for the third DCI, Therefore, the first network device can reasonably estimate the number of bits of the third UCI, so that based on the number of bits of the third UCI, it is determined that the terminal will send the third UCI on the first PUCCH resource set; in addition, because the first PUCCH resource is determined by the The first network device indicates to the terminal through the PUCCH resource indicator field of the third DCI, so the first network device knows that the terminal will send the third UCI on the first PUCCH resource. Therefore, the first network device will eventually receive (or detect) the third UCI on the first PUCCH resource on the first PUCCH resource set.

Step S809: The second network device receives the fourth UCI sent by the terminal.

Specifically, because the second network device does not add a fifth identifier to the TCI in the fourth DCI, the second network device knows that the UCI fed back by the terminal will include the HARQ-ACK for the TB of the fourth DCI but does not include the second CSI, so the second network device can reasonably estimate the number of bits of the fourth UCI, so that based on the number of bits of the fourth UCI, it is determined that the terminal will send the fourth UCI on the second PUCCH resource set; in addition, because the second PUCCH resource is The second network device indicates to the terminal through the PUCCH resource indicator field of the fourth DCI, so the second network device knows that the terminal will send the fourth UCI on the second PUCCH resource. Therefore, the second network device will eventually receive (or detect) the fourth UCI on the second PUCCH resource on the second PUCCH resource set.

In the method described in FIG. 8, the TCI of the third DCI sent by the first network device to the terminal carries a fifth identifier, thereby clarifying the association relationship between the second CSI and the third DCI to the terminal. After the terminal needs to feed back to the network the HARQ-ACK for the third DCI TB and the HARQ-ACK for the fourth DCI TB, the terminal encapsulates the second CSI and the HARQ-ACK for the third DCI TB in the same package. One UCI is not encapsulated in the same UCI as the HARQ-ACK for the TB for the fourth DCI. It can be seen that according to the TCI of the third DCI sent by the first network device, it can be predicted that the UCI for the third DCI includes the second CSI, so the first network device can reasonably estimate the size of the UCI for the third DCI, so Receive the UCI on the correct PUCCH resource set and PUCCH resource. Correspondingly, according to the TCI of the fourth DCI sent by the second network device, it can be predicted that the UCI for the fourth DCI does not include the second CSI, so the second network device can reasonably estimate the size of the UCI for the fourth DCI, so Receive the UCI on the correct PUCCH resource set and PUCCH resource.

Please refer to FIG. 9. FIG. 9 is a channel state information and hybrid automatic retransmission request confirmation multiplexing method provided by an embodiment of the present application. The method may be implemented based on the communication system shown in FIG. Limited to the following steps:

Step S901: The first network device sends a master DCI to the terminal.

Specifically, among the two DCIs sent to the terminal by the network side, one is the primary DCI and the other is the secondary DCI. The primary DCI may also be a DCI containing some or some specific parameters. Accordingly, the secondary DCI may be DCI that does not contain one or more specific parameters. Among them, the specific parameters may be carrier indication information (Carrier indication information), partial bandwidth indication information (Bandwidth indication information), rate matching indication information (Rate matching information), zero power channel state information reference signal trigger information (zero power channel-state information) --Reference signal trigger, ZP CSI-RS trigger). Step S902: The second network device sends a secondary DCI to the terminal.

Optionally, the reporting time slot of the HARQ-ACK of the TB of the primary DCI is the same as the reporting time slot of the HARQ-ACK of the TB of the secondary DCI, that is, the HARQ-ACK equivalent to the primary DCI and the HARQ-ACK of the secondary DCI are sent to Network side. Of course, the reporting slot of the HARQ-ACK of the TB of the primary DCI may be different from the reporting slot of the HARQ-ACK of the TB of the secondary DCI.

Step S903: The terminal receives the primary DCI and the secondary DCI.

Step S904: The terminal generates fifth uplink control information UCI according to the pre-configured information.

Specifically, the pre-configuration information defines an association relationship between the third CSI and the HARQ-ACK of the TB of the primary DCI, so the fifth UCI includes the third channel state information CSI and the primary CSI. The hybrid automatic retransmission request of the DCI transport block TB requests confirmation of HARQ-ACK.

Step S905: The terminal generates sixth uplink control information UCI according to the pre-configured information.

Specifically, the sixth UCI includes HARQ-ACK for the TB of the secondary DCI but does not include the third CSI, because the preset configuration information does not define the HARQ-ACK of the third CSI and the TB of the secondary DCI. The relationship between them.

Step S906: The terminal sends a fifth UCI to the first network device.

Specifically, the terminal determines which PUCCH resource set to use to send the fifth UCI according to the number of bits of the fifth UCI. The determined PUCCH resource set may be referred to as a third PUCCH resource set to facilitate subsequent description. In addition, the terminal also determines which PUCCH resource in the third PUCCH resource set sends the fifth UCI according to the PUCCH resource indicator field included in the main DCI. The determined PUCCH resource can be referred to as the third PUCCH resource to facilitate subsequent description. . After that, the terminal sends the fifth UCI on the third PUCCH resource on the third PUCCH resource set.

Step S907: The terminal sends a sixth UCI to the second network device.

Specifically, the terminal may also determine which PUCCH resource set to use to send the sixth UCI according to the bit number of the sixth UCI, and the determined PUCCH resource set may be referred to as a fourth PUCCH resource set to facilitate subsequent description. In addition, the terminal can also determine which PUCCH resource in the fourth PUCCH resource set sends the sixth UCI according to the PUCCH resource indicator field included in the secondary DCI. The determined PUCCH resource can be referred to as the fourth PUCCH resource to facilitate subsequent description. After that, the terminal sends the sixth UCI on the fourth PUCCH resource on the fourth PUCCH resource set.

Step S908: The first network device receives the fifth UCI sent by the terminal.

Specifically, because the pre-configuration information of the protocol specifies the association relationship between the third CSI and the HARQ-ACK for the TB of the main DCI, the first network device can also learn from the UCI that the terminal feeds back to its own UCI according to the pre-configuration information. Contains the third CSI and HARQ-ACK for the primary DCI TB, so the first network device can reasonably estimate the number of bits of the fifth UCI, so that based on the number of bits of the fifth UCI, it is determined that the terminal will send on the third PUCCH resource set The fifth UCI; in addition, because the third PUCCH resource is indicated to the terminal by the PUCCH resource indicator field of the primary DCI by the first network device, the first network device knows that the terminal will be at the third PUCCH resource Send the fifth UCI on. Therefore, the first network device will finally receive (or detect) the fifth UCI on the third PUCCH resource on the third PUCCH resource set.

Step S909: The second network device receives the sixth UCI sent by the terminal.

Specifically, since the association information of the third CSI and the HARQ-ACK of the TB for the primary DCI is specified in the pre-configuration information of the protocol, the second network device knows that the UCI that the terminal feedbacks to it will include the TB for the secondary DCI. HARQ-ACK does not include the third CSI, so the second network device can reasonably estimate the number of bits of the sixth UCI, so that based on the number of bits of the sixth UCI, it is determined that the terminal will send the sixth UCI on the fourth PUCCH resource set; In addition, since the fourth PUCCH resource is indicated to the terminal by the second network device through the PUCCH resource indicator field of the secondary DCI, the second network device knows that the terminal will send the sixth UCI on the fourth PUCCH resource . Therefore, the second network device will eventually receive (or detect) the sixth UCI on the fourth PUCCH resource on the fourth PUCCH resource set.

In an optional solution, after receiving the fifth UCI, the first network device parses the third CSI in the fifth UCI, and then sends the third CSI to the second network device. Accordingly, the second network device receives the third CSI.

In an optional case, the HARQ-ACKs of the TBs of multiple primary DCIs are configured to be sent in the same time slot. In this case, the fifth UCI includes the third CSI and the multiple CSIs. HARQ-ACK of the transport block TB of one of the main DCIs. That is, the UCI for the one primary DCI includes the third CSI, and the UCI for the other primary DCIs does not include the third CSI. The primary DCI may be a primary DCI specified in the protocol in advance (the content specified in the protocol may be known by the first network device and the terminal), or a primary DCI screened out according to a screening rule defined in the protocol ( The first network device and the terminal may filter out the same master DCI based on the filtering rule.

In the method described in FIG. 9, the pre-configuration information of the protocol specifies the association relationship between the third CSI and the HARQ-ACK of the TB for the primary DCI. Therefore, the terminal can learn that the third CSI and the primary DCI exist according to the pre-configuration information. Associated. After the terminal feeds back the HARQ-ACK for the TB of the primary DCI and the HARQ-ACK for the TB of the secondary DCI to the network, the terminal encapsulates the third CSI and the HARQ-ACK of the TB for the primary DCI in the same UCI. It is not encapsulated in the same UCI as the HARQ-ACK for the TB of the secondary DCI. In addition, the first network device can also learn that the UCI for the primary DCI contains the third CSI according to the pre-configuration information. Therefore, the first network device can reasonably estimate the size of the UCI for the primary DCI, so that the correct PUCCH resource set and PUCCH can be obtained. The UCI is received on the resource. Correspondingly, the second network device can also learn that the UCI for the secondary DCI does not include the third CSI according to the pre-configuration information. Therefore, the second network device can reasonably estimate the size of the UCI for the secondary DCI, so that the correct PUCCH resource is set. And receive the UCI on the PUCCH resource.

Please refer to FIG. 10. FIG. 10 is a channel state information and hybrid automatic retransmission request confirmation multiplexing method provided in an embodiment of the present application. The method may be implemented based on the communication system shown in FIG. Limited to the following steps:

Step S1001: The first network device sends a fifth DCI to the terminal.

Specifically, the DCI sent by the first network device to the terminal is referred to as a fifth DCI to facilitate subsequent description.

Step S1002: The second network device sends a sixth DCI to the terminal.

Specifically, the DCI sent by the second network device to the terminal is referred to as a sixth DCI to facilitate subsequent description. Optionally, the reporting slot of the HARQ-ACK of the TB of the fifth DCI is the same as the reporting slot of the HARQ-ACK of the TB of the sixth DCI, which is equivalent to the HARQ-ACK of the fifth DCI and the HARQ- of the sixth DCI. ACK needs to be sent to the network side at the same time. Of course, the HARQ-ACK reporting slot of the TB of the fifth DCI may be different from the HARQ-ACK reporting slot of the TB of the sixth DCI.

Step S1003: The terminal receives the fifth DCI and the sixth DCI in the first time slot.

Step S1004: The terminal generates a seventh UCI according to the fifth DCI, and generates an eighth UCI according to the sixth DCI.

Specifically, the communication system in which the first network device, the second network device, and the terminal are located can be pre-defined through a protocol, that is, the HARQ-ACK for the DCI TB is not encapsulated in the same UCI as the CSI. Therefore, the terminal is generating a seventh For UCI and eighth UCI, the seventh UCI includes the HARQ-ACK for the TB of the fifth DCI but does not include the fourth CSI, and the eighth UCI includes the HARQ-ACK for the TB of the sixth DCI but does not include the fourth CSI.

Step S1005: The terminal sends a seventh UCI to the first network device.

Specifically, the terminal determines which PUCCH resource set to use to send the seventh UCI according to the number of bits of the seventh UCI, and the determined PUCCH resource set may be referred to as a fifth PUCCH resource set to facilitate subsequent description. In addition, the terminal also determines which PUCCH resource in the fifth PUCCH resource set sends the seventh UCI according to the PUCCH resource indicator field included in the fifth DCI. The determined PUCCH resource can be referred to as the fifth PUCCH resource to facilitate subsequent follow-up. description. After that, the terminal sends the seventh UCI on the fifth PUCCH resource on the fifth PUCCH resource set.

Step S1006: The terminal sends an eighth UCI to the second network device.

Specifically, the terminal determines which PUCCH resource set to use to send the eighth UCI according to the number of bits of the eighth UCI. The determined PUCCH resource set may be referred to as a sixth PUCCH resource set to facilitate subsequent description. In addition, the terminal also determines which PUCCH resource in the sixth PUCCH resource set sends the eighth UCI according to the PUCCH resource indicator field included in the sixth DCI. The determined PUCCH resource can be referred to as the sixth PUCCH resource to facilitate subsequent description. After that, the terminal sends the eighth UCI on the sixth PUCCH resource on the sixth PUCCH resource set.

Step S1007: The first network device receives the seventh UCI.

Specifically, the first network device can know that the seventh UCI that the terminal will send to itself does not include the fourth CSI according to the protocol, so it can reasonably estimate the number of bits of the seventh UCI, and receive it on the correct PUCCH resource set and PUCCH resource. Seventh UCI. That is, the seventh UCI is received on the fifth PUCCH resource on the fifth PUCCH resource set.

Step S1008: The second network device receives the eighth UCI.

Specifically, the second network device can know that the eighth UCI that the terminal will send to itself does not include the fourth CSI according to the protocol, so the number of bits of the eighth UCI can be reasonably estimated, so as to receive on the correct PUCCH resource set and PUCCH resource Eighth UCI. That is, the eighth UCI is received on the sixth PUCCH resource on the sixth PUCCH resource set.

Step S1009: The terminal sends the fourth CSI to the first network device or the second network device according to the CSI reporting configuration information of the fourth channel state information CSI.

Optionally, the fourth CSI here refers to CSI that needs to be sent to the network side in the same time slot as the eighth UCI and the seventh UCI. The fourth CSI is not encapsulated in the seventh UCI or the eighth UCI, but is sent by the terminal to the network side, and the resource carrying the fourth CSI is the CSI report configuration information (CSI-ReportConfig) of the fourth CSI. Configured time-frequency resources. Further, the terminal may send the fourth CSI to the first network device on the network side or the second network device on the network side. Which network device is sent to which network device receives the fourth CSI accordingly. Optionally, one network device among the first network device and the second network device that has received the fourth CSI may send the fourth CSI to another network device.

In the method shown in FIG. 10, neither the seventh UCI fed back by the terminal to the first network device nor the eighth UCI fed back to the second network device will include the fourth CSI. The fourth CSI is independent of the HARQ-ACK. Sent to the network side. Accordingly, each time the first network device and the second network device receive the UCI, the fourth CSI need not be considered in the process of estimating the UCI bit number, and the first network device and the second network device respectively The estimated UCI bit size is received on the correct PUCCH resource set and PUCCH resource.

An embodiment of the method for determining multiplexing of channel state information and a hybrid automatic retransmission request shown in FIG. 7 described above, and the first network device sends the CSI report configuration information to the terminal, and the CSI report configuration information carries Downlink control information The downlink control information configuration information or downlink control parameters of the first DCI are described as an example. The terminal uses the physical uplink control channel PUCCH resource of the HARQ-ACK configured for the transmission block TB of the first DCI. Select one PUCCH resource in the set, and send the first UCI, where the first UCI includes the first CSI and HARQ-ACK for the TB of the first DCI. Therefore, the first network device can reasonably estimate the size of the UCI sent to the first network device, so as to receive the UCI on the correct PUCCH resource set and PUCCH resource.

An embodiment of a channel state information and hybrid automatic retransmission request determination multiplexing method shown in FIG. 8 is similar to this. A terminal sets a physical uplink control channel PUCCH resource set of a HARQ-ACK from a TB that is configured to transmit a third DCI. And selecting a PUCCH resource, and sending the third UCI, the third UCI including the second CSI and the HARQ-ACK for the third DCI TB. Therefore, the first network device can reasonably estimate the size of the UCI sent to the first network device, so as to receive the third UCI on the correct PUCCH resource set and PUCCH resource.

The embodiment of a channel state information and hybrid automatic retransmission request determination multiplexing method shown in FIG. 9 is similar to this.

And selecting a PUCCH resource to send the fifth UCI, the fifth UCI including the third CSI and the hybrid automatic retransmission request acknowledgement HARQ-ACK for the transport block TB of the primary DCI. Therefore, the first network device can reasonably estimate the size of the UCI sent to the first network device, so as to receive the fifth UCI on the correct PUCCH resource set and PUCCH resource.

If the CSI report configuration information does not carry any downlink control information configuration information or downlink control parameters of the DCI, if the first CSI and the HARQ-ACK of the transmission block TB of the first DCI, the HARQ-ACK of the TB of the second DCI When there is no overlap, the terminal executes the method described in FIG. 10, that is, the HARQ-ACK of the first CSI and the transmission block TB of the first DCI, and the HARQ-ACK of the TB of the second DCI select their respective PUCCH resources. Send UCI.

If one of the HARQ-ACKs of the first CSI and the transport block TB of the first DCI and the HARQ-ACK of the TB of the second DCI overlap, the terminal multiplexes the first CSI with the overlapping HARQ-ACK , And then send the remaining HARQ-ACK separately. If one of the HARQ-ACKs of the second CSI and the transmission block TB of the first DCI and the HARQ-ACK of the TB of the second DCI overlap, the terminal multiplexes the second CSI with the overlapping HARQ-ACK , And then send the remaining HARQ-ACK separately.

The embodiment of the method for determining multiplexing of channel state information and hybrid automatic retransmission request shown in FIG. 7 described above uses a network device to send CSI report configuration information to a terminal, and the CSI report configuration information carries downlink control information. The downlink control information configuration information or downlink control parameters of a DCI, and the HARQ-ACK of the TB corresponding to the DCI of the downlink control information configuration information or downlink control parameters are described as an example. The network equipment reports the downlink control information configuration information or downlink control parameters of the DCI carried in the configuration information by the CSI to instruct the terminal, and according to the downlink control information configuration information of the DCI or the indication of the downlink control parameters, the corresponding CSI and HARQ- ACK is fed back after multiplexing. The presence or absence of downlink control information configuration information or downlink control parameters of the DCI is equivalent to an instruction instructing the terminal how to feed back CSI and HARQ-ACK.

The following will describe how the terminal will feedback the CSI and HARQ-ACK if the downlink control information configuration information included in the CSI report configuration information or the HARQ-ACK of the TB of which the DCI does not correspond to the DCI.

In one case, as shown in FIG. 11, the PUCCH resource of the ninth CSI and the PUCCH resource of the HARQ-ACK of the transport block TB of the tenth DCI do not overlap.

In the foregoing channel state information and hybrid automatic retransmission request confirmation multiplexing method shown in FIG. 7, the HARQ-ACK of the first DCI transmission block TB multiplexed with the first CSI is The HARQ-ACK after the HARQ-ACK of the TB of the first DCI is merged with the HARQ-ACK of the TB of the other DCI, and the other DCI corresponds to the same downlink control configuration information or downlink control parameter as the first DCI, and Feedback in the same time unit. The HARQ-ACK of the transmission block TB of the second DCI is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the second DCI and the HARQ-ACK of the TB of another DCI, and the other DCI and the first DCI The two DCIs correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit.

Specifically, for CSI reporting configuration information carrying the same downlink control information configuration information or downlink control parameters, the corresponding multiple CSIs are called a set of CSI. The terminal needs to determine the overlap between PUCCH resources in the CSI report configuration information corresponding to a set of CSI. When the PUCCH resources are overlapped, it is necessary to determine the multiplexing between the CSIs and the corresponding PUCCH resources. In the group CSI, the CSI is sorted according to the priority of the multiplexed CSI from high to low, and then the CSI with the highest priority and the aforementioned CSI report configuration information include downlink control information configuration information or DCI transmission blocks corresponding to downlink control parameters. TB HARQ-ACK is multiplexed. Optionally, the HARQ-ACK of the transmission block TB of the DCI is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the DCI and the HARQ-ACK of the TB of another DCI, and the other DCIs are the same as the DCI. The downlink control configuration information or downlink control parameters, and feedback is required at the same time unit.

The downlink control information configuration information includes a seventh identifier of the control resource set CORESET; and the first DCI is a DCI carried on the CORESET identified by the seventh identifier.

In the foregoing channel state information and hybrid automatic retransmission request confirmation multiplexing method shown in FIG. 8, the HARQ-ACK of the third DCI transmission block TB is the HARQ of the third DCI TB. -HARQ-ACK after ACK is merged with HARQ-ACK of TB of other DCI, the other DCI and the third DCI correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit. The HARQ-ACK of the fourth DCI transmission block TB is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the fourth DCI and the HARQ-ACK of the TB of another DCI, and the other DCI and the first The four DCIs correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit.

For the TCI in the third DCI, the terminal needs to judge the fifth identifier in the TCI to determine the reference signal port identified by the fifth identifier, and then determine the corresponding DMRS group, and then determine the CSI-RS port group that has a QCL relationship with the DMRS group. For a CSI report configuration including a CSI-RS port in the group, the corresponding CSI is called a group of CSI. For a group of CSI, first determine the overlap between PUCCH resources. When the PUCCH resource is overlapped, it is necessary to determine the multiplexing between CSI and the corresponding PUCCH resource. In a group of CSI, After the CSI is used, the priority is sorted from high to low, and then the CSI with the highest priority is multiplexed with the HARQ-ACK of the transport block TB of the DCI corresponding to the aforementioned TCI. Optionally, the HARQ-ACK of the transmission block TB of the DCI is a HARQ-ACK combined by the terminal for at least one HARQ-ACK to be fed back for the DCI in a time slot.

When the terminal sends the third UCI to the first network device, the terminal selects a PUCCH resource from a physical uplink control channel PUCCH resource set configured to transmit the HARQ-ACK indicated by the third DCI, and sends the PUCCH resource. The third UCI is described.

In the foregoing channel state information and hybrid automatic retransmission request confirmation multiplexing method shown in FIG. 9, the HARQ-ACK of the transmission block TB of the primary DCI is the HARQ-ACK of the TB of the primary DCI. The HARQ-ACK after being merged with the HARQ-ACK of the TB of another DCI, the other DCI and the main DCI correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit. The HARQ-ACK of the transmission block TB of the secondary DCI is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the secondary DCI and the HARQ-ACK of the TB of another DCI, and the other DCIs correspond to the secondary DCI. The same downlink control configuration information or downlink control parameters are fed back in the same time unit.

The third CSI is the CSI with the highest priority among the multiple CSIs corresponding to the primary DCI. Optionally, at least one of the multiple CSIs is CSI after CSI multiplexing.

Specifically, the terminal needs to determine the PUCCH resources in the CSI reporting configuration information corresponding to multiple CSIs (a group of CSIs). When the PUCCH resources are overlapped, it is necessary to determine the multiplexing between the CSIs and the corresponding PUCCH resources. In the CSI, the priority of the CSI after multiplexing is sorted from high to low, and then the CSI with the highest priority is multiplexed with the HARQ-ACK of the aforementioned transport block TB of the main DCI. Optionally, the HARQ-ACK of the transmission block TB of the primary DCI is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the primary DCI and the HARQ-ACK of the TB of another DCI, and the other DCI and the The primary DCI corresponds to the same downlink control configuration information or downlink control parameters, and needs to be fed back at the same time unit. Optionally, the terminal selects one PUCCH resource from the set of physical uplink control channel PUCCH resources configured to transmit the HARQ-ACK indicated by the fifth DCI, and sends the fifth UCI. The terminal selects one PUCCH resource from the set of physical uplink control channel PUCCH resources configured to transmit the HARQ-ACK indicated by the sixth DCI, and sends the sixth UCI. Optionally, when there is no primary DCI in the current time slot, the terminal selects a PUCCH resource based on the number of UCI bits from the physical uplink control channel PUCCH resource set of the HARQ-ACK configured to transmit the transmission block TB of the primary DCI , Sending the fifth UCI.

In the foregoing channel state information and hybrid automatic retransmission request confirmation multiplexing method shown in FIG. 10, the HARQ-ACK of the fifth DCI transmission block TB is the HARQ of the fifth DCI TB. -HARQ-ACK after ACK is merged with HARQ-ACK of TB of other DCI, the other DCI and the fifth DCI correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit. The HARQ-ACK of the sixth DCI transmission block TB is a HARQ-ACK obtained by combining the HARQ-ACK of the TB of the sixth DCI and the HARQ-ACK of the TB of another DCI, and the other DCI and the first DCI Six DCIs correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit.

In the foregoing channel state information and hybrid automatic retransmission request confirmation multiplexing method shown in FIG. 11 to FIG. 15, the HARQ-ACK of the tenth DCI transmission block TB is the value of the tenth DCI. The HARQ-ACK of the TB's HARQ-ACK combined with the HARQ-ACK of the other DCI's TB. The other DCI and the tenth DCI correspond to the same downlink control configuration information or downlink control parameters, and are fed back in the same time unit .

The ninth CSI is the downlink control information configuration information of the ninth DCI or the CSI with the highest priority among the multiple CSIs corresponding to the downlink control parameters. Optionally, at least one of the multiple CSIs is CSI after CSI multiplexing.

Specifically, for CSI reporting configuration information carrying the same downlink control information configuration information or downlink control parameters, the corresponding CSI is called a set of CSI. The terminal needs to determine the overlap between PUCCH resources in the CSI report configuration information corresponding to a set of CSI. When the PUCCH resources are overlapped, it is necessary to determine the multiplexing between the CSIs and the corresponding PUCCH resources. In the group CSI, the CSI is sorted according to the priority of the multiplexed CSI from high to low, and then the CSI with the highest priority is reported as the ninth CSI.

In the foregoing embodiments shown in FIG. 7 and FIG. 11-15, description is made by adding downlink control information configuration information or downlink control parameters to the CSI report configuration information (CSI-report-config) as an example, for example, adding a control resource set identifier (CORESET id) and so on, to instruct the terminal to report the corresponding CSI and HARQ-ACK after multiplexing.

In another implementation manner, downlink control information configuration information or downlink control parameters may be prescribed or fixed by default in the protocol to indicate the terminal. For example, the CORESET ID, PDCCH-Config ID, searchspace ID, or scrambling code identifier are set to a certain fixed value. For example, a total of 3 CORESETs are specified in the protocol, where CORESET0 is used for public DCI, CORESET1 corresponds to a different first network device, CORESET2 corresponds to a second network device, and the CSI transmitted on the PUCCH resource is periodic or semi-static , So you can specify a CORESET.

At this time, a signaling is first required to notify the terminal to bind the CSI to a certain downlink control information configuration information or downlink control parameter, for example, CORESET id is 1, or PDCCH-Config id is 1, etc. The signaling can be It is a separate signaling, which can also be implemented using CSI-report-config or PUCCH-config, and can also be specified through a protocol.

The terminal first determines the PUCCH resource locations in the CSI-report-config corresponding to multiple CSIs. According to the overlap between resource locations, when the PUCCH resources are overlapped, the CSI is first multiplexed, and the multiplexing is determined. PUCCH resources corresponding to the subsequent CSI; then, the CSI after multiplexing is sorted according to the priority from high to low.

If CORESET id = 1 in this time unit and there is an associated ACK, the CSI is always multiplexed and fed back with the ACK associated with CORESET id = 1. For details, refer to the foregoing embodiment shown in FIG. 7. If the CORESET id is 1, and there is no associated ACK, operate according to any one of the foregoing embodiments corresponding to FIG. 11 to FIG. 15.

In another implementation manner, regardless of whether downlink control information configuration information or downlink control parameters are added to the CSI report configuration information (CSI-report-config), the terminal selects the multiplexing situation by itself.

When there is no overlap between CSI and HARQ-ACK, all PUCCHs can be sent separately;

When CSI and HARQ-ACK overlap, the terminal can choose various multiplexing schemes. For example, the feedback sent to the first network device is the HARQ-ACK of the TB of the first CSI and the first DCI, and the feedback sent to the second network device is the HARQ-ACK of the TB of the second CSI and the second DCI.

In specific implementation, it is performed as follows:

Step 1: If there are multiple CSIs, the terminal first determines whether the PUCCH resources of the first CSI and the second CSI overlap.

If yes, firstly multiplex the first CSI and the second CSI, and then sort the multiplexed CSI according to the priority to find the first priority CSI;

If not, find the first priority CSI by priority;

If there is only one CSI, perform the second step directly;

Step 2: The terminal determines the multiplexing situation between the CSI and the HARQ-ACK (referred to as ACK1) of the TB of the first DCI and the HARQ-ACK (referred to as ACK2) of the TB of the second DCI. If there is no overlap between the three, the terminal can send three PUCCHs, each carrying CSI, ACK1, and ACK2.

If there is an overlap between CSI and ACK1 and no overlap with ACK2, the terminal can send 2 PUCCHs, one PUCCH contains CSI + ACK1, and one PUCCH contains ACK2;

Similarly, if there is an overlap between CSI and ACK2 and no overlap with ACK1, the terminal can send two PUCCHs, one PUCCH contains CSI + ACK2, and one PUCCH contains ACK1.

If CSI overlaps with ACK1 and ACK2 at the same time, the terminal's behavior is specified to send two PUCCHs, one PUCCH contains CSI + ACK1 and one PUCCH contains CSI + ACK2; or the terminal's behavior is specified to send two PUCCH, one containing CSI + ACK1, one PUCCH contains ACK2; or the behavior of the terminal is to send two PUCCHs, one containing ACK1 and one PUCCH containing CSI + ACK2.

For the first network device, two possibilities are actually received:

CSI and ACK1 are on the corresponding PUCCH resources;

For CSI + ACK1 multiplexing, the method of determining the PUCCH resource for transmitting ACK1 is used to determine the PUCCH resource for transmitting CSI + ACK1.

In this implementation, the terminal multiplexes CSI and HARQ-ACK according to its own selection, and the network device performs multiple detections on the corresponding resources.
