The following first describes what the scheme provided by the embodiment of the present application relates to.

In an NR (new air interface) system, a downlink channel includes a downlink data channel PDSCH (downlink shared channel) and a downlink control channel PDCCH, and an uplink channel includes an uplink data channel PUSCH (uplink shared channel) and an uplink control channel PUCCH. For high frequency transmission (FR 2 band in NR), due to the limited transmission range, the uplink and downlink channels are typically beamformed and then transmitted to enhance coverage. The direction of the shaped beam can be determined by beam scanning of uplink and downlink reference signals, for example, CSI (channel state information) -RS (reference signal) or SRS (sounding reference signal) in different directions are used for beam scanning, and the direction of the reference signal with the best beam quality is selected for uplink or downlink transmission. The beam directions of the different channels are determined and the beam at the time of channel transmission, i.e. beam indication, needs to be indicated using signaling. Currently, for PUCCH, a base station is configured to a terminal in multiple beam directions through higher layer signaling spacialrelation info semi-statically, and instructs to activate one of them through MAC (media access control) -CE (control element). For PUSCH, the uplink beam selected by the base station is indirectly indicated by the spatlrelationinfo of the SRS resource indicated by the SRI (SRS Resource Index ) field in the dynamic signaling DCI (downlink control information). For the PDCCH channel, the base station configures a plurality of TCI states for each CORESET by higher layer signaling and activates one of them by MAC-CE indication. For PDSCH channels, the base station indicates a TCI state through the TCI field in DCI signaling, indicating the beam direction of the channel.

Different channels use different beam indication signaling and each channel is beam indicated independently. Such that different channels may be transmitted using respectively different beams. An important scenario in practical applications is that multiple channels use the same beam direction. For example, the same beam direction transmission is used between the PDCCH for resource scheduling and the PDSCH for transmitting user data; the same beam direction is also used for the uplink control channel PUCCH and the uplink data channel PUSCH. When beam reciprocity exists, the uplink and downlink channels will also use the same beam direction. At this time, the current way of independent beam indication increases the complexity of the system and the signaling indication overhead. To overcome the above problems, a method of indicating a plurality of channel beams using one beam indication signaling is currently introduced, which activates a set of TCI states through a MAC-CE and then indicates one of the activated TCI states using DCI. When the uplink and downlink channels are reciprocal, the beam indicated by the beam indication signaling can be used for both the uplink channel and the downlink channel; when MPE (Maximum Permissible Exposure, maximum allowed radiation) problems due to human body occlusion occur or the terminal needs to switch the uplink beam, the uplink channel will use a different beam than the downlink channel, so the beam indication signaling needs to indicate the uplink channel beam and the downlink channel beam, respectively.

Based on the above, the embodiments of the present application provide an information transmission method, apparatus, network device, and terminal, so as to solve the problem that an information transmission scheme for multi-TRP transmission in the prior art cannot support implementation. The method, the device, the network equipment and the terminal are based on the same application conception, and because the method, the device, the network equipment and the terminal have similar principles for solving the problems, the implementation of the method, the device, the network equipment and the terminal can be mutually referred to, and the repetition is omitted.

2. determining a TCI state value corresponding to the first resource group based on the TCI state value indicated by the first indication signaling (which can be understood as a specific TCI state value); under the condition that the TCI state value corresponding to the first resource group is determined, determining the TCI state value corresponding to the second resource group according to the corresponding relation;

3. Determining TCI state information corresponding to the first resource based on TCI state information (which can be understood as a specific TCI state value) indicated by the first indication signaling; under the condition that the first TCI state information corresponding to the first resource group (such as 2 resources) is determined, determining another TCI state value according to the determined one TCI state value and the corresponding relation;

4. determining a specific TCI state value based on the TCI state value indicated by the first indication signaling; determining the TCI state value of the resource or the resource group according to the determined specific value (specifically, the TCI state value can be indicated by a first indication signaling) and the corresponding relation (such as indicating the specific value of the use number);

5. determining a specific TCI state value based on the TCI state value indicated by the first indication signaling; determining the TCI state value of the resource or the resource group according to the determined specific value of the TCI state and the corresponding relation (such as indicating the specific value of the use, wherein the first parameter identifier is used for indicating the resource or the resource group);

6. determining a specific TCI state value based on the TCI state value indicated by the first indication signaling; and determining the TCI state value of the resource or the resource group according to the determined specific value of the TCI state and the corresponding relation (such as indicating the specific value of the TCI state information associated with the first parameter identifier).

Further, the first information further includes: a first correspondence; or the first indication signaling carries a first corresponding relation; wherein the first correspondence relationship includes: at least one of a (first) corresponding relation between a resource or a resource group and TCI state information, a (second) corresponding relation between a first parameter identification and TCI state information, or a (third) corresponding relation between a resource or a resource group and a first parameter identification; the first parameter identification is used to identify a resource or group of resources.

In this way a multi-way transmission of the first correspondence can be achieved. Further, based thereon, determining at least one TCI state value corresponding to the at least one resource or resource group according to the first indication signaling and the first correspondence may comprise at least one of:

1. determining at least one TCI state value according to the first instruction, and determining a target resource and a corresponding target TCI state information value (TCI state information such as a TCI state of a TCI item indicated by the first instruction) according to the corresponding relation in the first item;

2. determining at least one TCI state value according to the first indication instruction, and determining a target identifier and corresponding target TCI state information according to the corresponding relation in the second item, thereby determining the TCI value corresponding to the target identifier; corresponding target resources can be determined according to the target identification;

Determining at least one TCI state value according to the first indication instruction, and determining a target resource and a corresponding target identifier according to the corresponding relation in the third item; corresponding default TCI state information (target TCI state information) can be determined according to the target resource or the target identifier, and then the TCI value corresponding to the target resource or the target identifier is determined.

In the embodiment of the present application, the correspondence between the resources or the resource groups and the TCI status information includes: a first sub-relationship between the resource or resource group and a TCI state value indication; and/or, the correspondence between the first parameter identifier and the TCI state information includes: a second sub-relationship between the first parameter identification and the TCI state value indication; wherein the TCI state value indication is used to identify the TCI state information.

This allows an indirect determination of the correspondence.

This may enable the present solution for multiple situations.

In the embodiment of the present application, the receiving the first correspondence relationship sent by the network device includes at least one of the following: receiving TCI state information which is sent by network equipment and is indicated or configured for at least one resource or resource group; or, receiving a resource or a resource group or a first parameter identifier corresponding to TCI state information sent by network equipment; or, receiving TCI state information corresponding to the scheduled resources, which is indicated by the network equipment through the resource scheduling signaling.

In this way, the content transmission for the first correspondence may be specifically implemented (which may also be understood as how the network device specifically informs the terminal of the first correspondence by means of signaling). The corresponding relation between the information domain value and the TCI state information in the resource scheduling signaling is predefined or indicated to the terminal by the network equipment.

This may enable dynamic switching of single TRP transmissions with multiple TRP transmissions, or specific transmissions of single TRP. The terminal can perform TRP transmission switching according to the TRP information domain; or determining the TCI state value used in single TRP transmission according to the TRP information domain.

Wherein the TRP information field is used for indicating all channels and/or signals or for indicating part of channels and/or signals. This may enable TRP transmission indications for at least part of the channel or signal. The terminal may determine the TCI status value of all channels and/or signals or the TCI status value of part of channels and/or signals according to the TRP information field.

In an embodiment of the present application, the first indication signaling includes: at least one TCI state value indicative of a field. This allows an accurate indication of the TCI state specific value. The terminal may determine at least one TCI state value corresponding to at least one resource or resource group according to the indication field of the TCI state value.

This way the present solution can be implemented for multiple scenarios.

11 The resource grouping described in 2) may be configured through one or more of RRC signaling, MAC-CE signaling, and DCI.

14 The first correspondence described in 1) may be predefined by the system, in which case the first correspondence need not be received, including:

its corresponding TCI state information is predefined for each resource or resource group. And determining at least one TCI state value corresponding to at least one resource or resource group according to the first information and the first predefined information.

The following specifically exemplifies the scheme provided in the embodiment of the present application.

Example 1:

the base station indicates 2 TCI states (corresponding to the transmission of the first indication signaling to the terminal) to the terminal through DCI signaling or first MAC-CE signaling, where the TCI states correspond to the TCI states. The base station configures 5 CORESETs for the terminal through RRC signaling, denoted CORESET #0, CORESET #1, …, CORESET #4, respectively. Meanwhile, the base station configures a mapping relation (corresponding to the first corresponding relation) between the TCI state indicated by the DCI and the CORESET for the terminal, and the mapping relation is used for transmitting the CORESET. The mapping relationship may be configured through MAC-CE or RRC signaling. (1) One way is that RRC signaling indicates in the configuration of each CORESET whether it uses the first or the second of the 2 TCI states, or uses the 2 TCI states, by configuring tci_use (usage, which can be understood as selection; corresponding to the TCI state value indication described above). For example, the following configuration is adopted:

Which represents the first TCI state of the CORESET #2 usage indication. Or in the following configuration(s) may be employed,

which indicates that CORESET #2 uses both the indicated first TCI state and the indicated second TCI state. It can be applied to high-speed rail scenes.

(2) Another implementation manner is that the CORESET group (i.e., CORESET packet or CORESET set) is configured by RRC, and the base station configures, for the terminal, a mapping relationship (corresponding to the first correspondence relationship) between a TCI state (corresponding to the TCI state indication) and the CORESET group. Packet 1 includes { CORESET#0, CORESET#1, CORESET#2}, and packet 2 includes { CORESET#3, CORESET#4}. The first TCI state and the second TCI state may be configured for use in packet 1 and the second TCI state may be configured for use in packet 2. It is also possible that the CORESET in packet 1 uses two TCI states and the first TCI state in packet 2 by system conventions. At this time, the TCI state used need not be configured in the packet. The CORESET IDs in the CORESET group may be updated by MAC-CE. That is: one is that the base station carries the indication information of the TCI state (value indication) used in the configuration of the CORESET group; one is a system contract whereby the TCI state (value indicator) used is known from the CORESET ID.

(3) Another implementation manner is that the RRC signaling configures a CORESET corresponding to a first TCI state (value indication) of the indication and a CORESET corresponding to a second TCI state of the indication. For example, the RRC configures a first TCI state association { CORESET#0, CORESET#1}, and a second TCI state association { CORESET#2, CORESET#3, CORESET#4}. It is also possible that the RRC configures the first TCI state association { CORESET#0, CORESET#1, CORESET#3}, the second TCI state association { CORESET#2, CORESET#3, CORESET#4}. Here CORESET #3 uses two TCI states, which can be used for high-speed rail scenarios.

(4) Another implementation is to use MAC-CE signaling to indicate the association (i.e., the association of TCI state with the CORESET set). For example, in MAC-CE signaling to activate TCI status, the CORESET associated with each TCI status bit is added (i.e., CORESET packets, in which case the aforementioned tci_use parameter configuration is not required), as follows:

TABLE 1 TCI State activated in MAC-CE Signaling (correspondence of TCI State to set)

/>

Wherein the activated TCI state-1 is associated with { CORESET#0, CORESET#1}, and the activated TCI state-2 is associated with { CORESET#2, CORESET#3, CORESET#4}. When the DCI signaling indicates one code point "001", coreset#0 and coreset#1 are transmitted using the first TCI State TCI-State 9; CORESET #2, CORESET #3, and CORESET #4 are transmitted using the second TCI State TCI-State 10. Alternatively, the configuration is as follows:

TABLE 2 activated TCI State in MAC-CE Signaling

Wherein CORESET #4 uses two TCI state transmissions, applicable to high-speed rail scenarios.

(5) Another implementation is that the MAC-CE indicates the TCI state (value) of each CORESET or each CORESET packet. For example, RRC configures 3 CORESETs for the terminal. As in table 3, a corresponding TCI state is configured for each CORESET in the mac-CE activation signaling. Wherein the TCI states of CORESET #1 and CORESET #2 are the same, meaning that they use the same TRP transmission.

TABLE 3 activated TCI State in MAC-CE Signaling

(6) Another implementation is to employ DCI signaling indication. A TCI usage association field may be included in the DCI signaling indicating the TCI status (value) at the base station, indicating the TCI status used by different CORESET or different CORESET packets. For example, CORESET is grouped, where group 1 includes { CORESET#0, CORESET#1, CORESET#2}, and group 2 includes { CORESET#3, CORESET#4}; packet configuration may be performed using RRC signaling. The DCI includes a TCI field (an indication field corresponding to the TCI state value) for indicating the TCI state. Meanwhile, the DCI can also contain a TCI usage association domain. 1) One implementation is that the TCI uses an indication of the manner in which the association domain adopts the code point state, for example as follows:

TCI domain	TCI uses association domains
		011	00

Wherein the TCI usage association field may include 2 bits, "00" for a first TCI state (value) indicated by packet 1 using the TCI field and a second TCI state indicated by packet 2 using the TCI field, "01" for a second TCI state indicated by packet 1 using the TCI field and a first TCI state indicated by packet 2 using the TCI field, "10" for a first TCI state indicated by both packet 1 and packet 2 using the TCI field, and "11" for a second TCI state indicated by both packet 1 and packet 2 using the TCI field. It is also possible to indicate by code point that packet 1 uses two TCI states, or packet 2 uses two TCI states, etc. Assuming "011" corresponds to TCI-State25 and TCI-State29, it can be determined from the TCI using the associated domain indication: packet 1 uses TCI-State25 and packet 2 uses TCI-State29.

2) In another implementation manner, the TCI in the DCI uses a bitmap method to indicate the TCI state (value) used by each CORESET. The following are provided:

TCI domain	TCI uses association domains
		011	00101

The TCI uses an association field containing 5 bits. Each bit corresponds to a CORESET, taking 0 to indicate the use of a first TCI state and taking 1 to indicate the use of a second TCI state; then assuming "011" corresponds to TCI-State25 and TCI-State29, it is determined that: CORESET#0, CORESET#1, CORESET#3 uses TCI-State25, CORESET#2 and CORESET#4 uses TCI-State29.

Example 2:

the base station configures PUCCH resource groups for the terminal, where each PUCCH resource group includes one or more PUCCH resources, or the base station configures a number of the resource group for each PUCCH resource. The PUCCH resources in the resource group may be updated through MAC-CE signaling. The base station indicates 2 TCI states (corresponding to the transmission of the first indication signaling to the terminal) to the terminal through DCI signaling or first MAC-CE signaling, where the TCI states correspond to the TCI states. The terminal needs to determine the corresponding relation (corresponding to the first corresponding relation) between the TCI state indicated by the base station and the PUCCH resource group or PUCCH resource, so that each PUCCH resource uses the corresponding TCI state for transmission.

Specific implementation examples are provided below:

(1) One implementation is that the system predefines the correspondence of PUCCH resource groups to TCI states. For example, the base station configures 2 PUCCH resource groups for the terminal, and agrees that resource group 1 corresponds to 2 TCI states (values) indicated by the base station, and resource group 2 corresponds to the first TCI state indicated by the base station. If the base station indicates TCI-State9 and TCI-State10, each PUCCH resource in resource group 1 will use both states for transmission. The specific transmission may be that a plurality of transmission opportunities of one PUCCH resource in resource group 1 are sequentially mapped cyclically to a transmission beam (denoted by # 1) corresponding to tci_state9 and a transmission beam (denoted by # 2) corresponding to tci_state 10. Taking 4 transmissions as an example, the mapping pattern of the transmit beam is #1#2#1#2, corresponding to two TRP transmissions. And for each PUCCH resource in resource group 2, only the transmit beam corresponding to tci_state9 is used for transmission, corresponding to single TRP transmission. Or the base station configures 3 PUCCH resource groups for the terminal, and agrees that the resource group 1 corresponds to 2 TCI states indicated by the base station, the resource group 2 corresponds to a first TCI state indicated by the base station, and the resource group 3 corresponds to a second TCI state indicated by the base station.

(2) Another implementation is to indicate the correspondence of PUCCH resource groups (i.e. PUCCH packets) to TCI states using MAC-CE signaling. For example, in MAC-CE signaling that activates TCI status, the PUCCH resource group associated with each TCI status bit is added. Similar to example 1 (see relevant contents of tables 1 to 3), the CORESET packet corresponds to the PUCCH resource group, and will not be described again.

(3) Another implementation is to employ DCI signaling indication. A DCI signaling indicating the TCI status by the base station may include a TCI usage association field, which indicates the TCI status (value) used by different PUCCH packets. Specifically similar to example 1 (similar to, for example, grouping CORESET, where grouping 1 includes { CORESET #0, CORESET #1, CORESET #2}, grouping 2 includes { CORESET #3, CORESET #4}, grouping configuration may be performed using RRC signaling. In DCI, a TCI field (an indication field corresponding to the TCI state value described above) is included for indicating the TCI state.

(4) Another implementation is to employ DCI signaling indication. The DCI signaling of the base station indicating the TCI state comprises a TCI use association field which indicates the TCI state of the PUCCH resource use for uplink ACK or NACK feedback. Similar to example 1 (similar to the DCI signaling indicating the TCI state in the base station may include a TCI usage association field, indicating the TCI state used by different CORESETs or different CORESET packets; PUCCH resources correspond to CORESETs), and will not be described in detail.

(5) The present example may also configure the TCI state used by each PUCCH resource or each PUCCH resource set (for example, there is no state group corresponding to TCI1 or no state group corresponding to TCI2, the TCI state is directly configured in each resource and resource set, and the TCI state corresponds to the TCI state value indication described above). For example, the following are possible:

/>

which indicates that the PUCCH resource uses a first TCI state and a second TCI state.

Example 3:

the base station indicates 2 TCI states (corresponding to the first indication signaling sent to the terminal and the TCI states are corresponding to the TCI state values) for the terminal through DCI signaling or first MAC-CE signaling, and the TCI states are used for transmitting PUSCH; a mapping relationship (corresponding to the first correspondence relationship described above) between the TCI state and the PUSCH transmission occasion needs to be indicated.

Specific implementation examples are provided below:

(1) One implementation is to configure the TCI state it uses in each SRS resource set or each SRS resource (PUSCH transmission occasion has a correspondence with SRS resource set). Such as:

which represents the SRS resource set using the first TCI state. And according to the corresponding relation between the PUSCH transmission opportunity predefined by the system and the SRS resource set, realizing repeated transmission using different TCI states.

(2) Another implementation is to configure the TCI state (value indication) it uses in PUSCH configuration. PUSCH uses the first TCI state and the second TCI state for mTRP (multi-TRP) transmission (system fixable transmission occasion vs TCI state) as follows. This approach can be used for repetition transmission of unlicensed PUSCH. The system predefines that the first retransmission uses a first TCI state and the second retransmission uses a second TCI state.

PUSCH-Config: =sequence {

TCI_usage 1，2

}

(3) Another implementation is that the system predefines the correspondence of the code points in the 2-bit SRS resource set(s) field in the DCI with the TCI state (value indication). For example, the system predefines the following (see table below) mapping. Where "00" indicates a single TRP transmission, and each transmission occasion uses the first TCI state indicated by the base station for PUSCH transmission. Where "10" indicates a multi-TRP transmission, a first transmission occasion uses a first TCI state for PUSCH transmission, a second transmission occasion uses a second TCI state for PUSCH transmission, and so on. The column of SRS resource set domain may not be included.

Where TPMI represents a transmit precoding matrix indicator.

(4) Another implementation is to use MAC-CE signaling to indicate the association (i.e., the correspondence of TCI state to SRS resource set). For example, in MAC-CE signaling that activates TCI state, the SRS resource set (SRS resource set) associated with each TCI state bit is added. Similar to example 1 (see relevant contents of tables 1 to 3), the CORESET packet corresponds to the SRS resource set, and will not be described again.

Example 4:

(1) The base station indicates 2 TCI states (corresponding to the transmission of the first indication signaling to the terminal) to the terminal through DCI signaling, where the TCI states correspond to the TCI states. The DCI signaling comprises sTRP (single TRP) and/or mTRP (multiple TRP) indication domains. The indication field contains 2 bits, and the system predefines the correspondence between the code points in the indication field and the TCI state (corresponding to the first correspondence described above). The correspondence may be as follows:

Codepoint	Correspondence relation
		00	sTRP, using first TCI state
01	sTRP, using the second TCI state
		10	mTRP, using two TCI states
11	mTRP, using two TCI states

According to the correspondence, the base station adopts 1 TRP or two TRPs to transmit PDSCH.

(2) Another implementation is that the base station indicates 1 or 2 TCI states (values) to the terminal through DCI signaling. Meanwhile, the DCI signaling comprises sTRP and/or mTRP indication domains. The system predefines the correspondence of code points in the indication field to TCI states as shown in the table below. When the base station indicates 2 TCI states, the meaning of the above table is the same, i.e. srp or mTRP transmission is used. And when the base station indicates 1 TCI state, when either '10' or '11' is indicated, it indicates that mTRP transmission is still employed and one of the current two TCI states is updated (i.e., changed).

Example 5:

when the base station configures coresetpoolndex for the terminal, it means that M-DCI (multi-DCI) is used for scheduling (corresponding to transmitting the above-mentioned first indication signaling to the terminal). The base station may indicate a correspondence (corresponding to the first correspondence described above) of TCI status (value indication) to coresetpoil index. (1) One way may be to configure the coresetpoolndex corresponding to each TCI state in the MAC-CE signaling that activates the TCI state; the corresponding TCI state may also be configured by RRC under each CORESET, e.g. corresponding to the first TCI state or corresponding to the second TCI state, while requiring the TCI states of coreets corresponding to the same coresetpoolndex to be the same; two TCI indication fields (indication fields corresponding to the above TCI state values) may be configured in the DCI indicated by TCI, where the first TCI indication field indicates the TCI state corresponding to coresetpoindindex 0 and the second TCI indication field indicates the TCI state corresponding to coresetpoindindex 1, as shown in the following table. When only the TCI state corresponding to one coresetpoolndex is indicated, the other TCI indication field is set to inactive.

TCI Domain/CORESEETPoolIndex 0	TCI Domain/CORESEETPoolIndex 1
		011	001

(2) Another way is to indicate TCI status (value) and coresetpoolndex information in DCI indicated by TCI. For example, the following are possible:

TCI domain	CORESETPoolIndex
		011	0

It means that the TCI state indicated by the TCI field is applied to CORESET corresponding to coresetpoolndex 0 and its scheduled PDSCH.

Example 6:

in order to realize uplink multi-panel simultaneous transmission, the terminal needs to correspond the TCI state indicated by the base station (corresponding to the first indication signaling, where the TCI state corresponds to the TCI state value) to different panels of the terminal (corresponding to determining, by the terminal, the TCI state value of a panel according to the first correspondence), so that each panel corresponds to one transmission beam (one beam corresponds to one TCI state value). (1) One implementation manner is to configure a correspondence between the TCI state and the SRS resource set (corresponding to the first correspondence described above; there is a correspondence between the SRS resource set and the panel), and the terminal may determine this correspondence, which may be specifically default. The configuration manner of the correspondence between the TCI state and the SRS resource set is similar to example 3, and will not be described herein. Specifically, it is assumed that the terminal transmits SRS resource set0 using panel0 and SRS resource set1 using panel 1. When the base station indicates two TCI states and schedules PUSCH transmission, the terminal performs uplink transmission by using the TCI state corresponding to SRS resource set0 and by using the TCI state corresponding to SRS resource set1 according to the mapping relationship (i.e., the correspondence relationship).

(2) Another implementation manner is to configure a corresponding relationship (corresponding to the first corresponding relationship) between the TCI state (value indication) and the maximum antenna port number index of the parameter Panel. Wherein the maximum antenna port number index of a panel corresponds to a different panel. 1) One configuration may be to indicate this correspondence in DCI signaling for beam indication. For example, a corresponding relation field is added in the DCI, and meanwhile, a predefined relation field value (corresponding to a code point code) of the system is related to the corresponding relation field value as follows:

2) Another implementation is to indicate the association using MAC-CE signaling. For example, in MAC-CE signaling that activates TCI status (takes on value), the maximum antenna port number index of the Panel associated with each TCI status bit is increased. Similar to example 1 (similar to adding CORESET associated with each TCI state bit in MAC-CE signaling for active TCI state; maximum antenna port number index corresponds to CORESET), details are not repeated here.

(3) Another implementation may be to configure the correspondence between the TCI state (value indication) and the maximum antenna port number index of the panel through RRC signaling.

Example 7:

in the above examples 1-6, the base station indicates 2 TCI states (corresponding to the first indication signaling sent to the terminal, where the TCI states correspond to the TCI states, where each TRP and the terminal use one beam; it is also possible that the base station indicates 3 TCI states (denoted as tci_state0, tci_state1, tci_state2) for the terminal. Wherein a beam is used between TRP0 and the terminal, namely the uplink and downlink beams are the same; two beams are used between TRP1 and the terminal, and different beams are used for uplink and downlink. In this case, the first TCI state-to-resource or resource group (e.g., coresetpoolndex, etc.) correspondence described in examples 1-6 may correspond to the first TCI state information as the resource or resource group. Wherein the first TCI state information includes a first TCI state indication (e.g., TCI state0 is indicated). The corresponding relationship (including the first corresponding relationship) between the second TCI state and the resource or the resource group may be the corresponding relationship between the second TCI state information and the resource or the resource group. Wherein the second TCI state information includes a second TCI state indication and a third TCI state indication (e.g., tci_state1 and tci_state2). Similarly, the base station may also indicate 4 TCI states for the terminal. Wherein the uplink and the downlink between TRP0 and the terminal use different beams, and the uplink and the downlink between TRP1 and the terminal use different beams. In this case, the first TCI state information includes a first TCI state indication and a second TCI state indication; the second TCI state information includes a third TCI state indication and a fourth TCI state indication. Thus, unlike TCI state values, each TCI state information may include 1 or more TCI state value indications for indicating at least 1 TCI state value.

Example 8:

the system predefines a correspondence (corresponding to the first correspondence described above) of downlink PDCCH resources and uplink PUCCH resources or PUSCH resources with respect to TCI usage. For example, (1) the system predefines the association of PDCCH resources with their scheduled PUCCH resources using the same TCI state (value indication). If the CORESET where the PDCCH resource is located configures the indicated first downlink TCI state (value), the PUCCH resource scheduled by the PDCCH resource uses the indicated first uplink TCI state. If the base station indicates two downlink TCI states (values) and two uplink TCI states, they are respectively indicated as DL (downlink) -TCI-State9 and DL-TCI-State23, UL (uplink) -TCI-State5 and UL-TCI-State17. If CORESET #1 is configured to use the first downstream TCI State (value), CORESET #1 is transmitted using DL-TCI-State 9. According to the predefined rule, the PUCCH does not need to reconfigure the correspondence with the TCI state (value): at this time, the PUCCH scheduled by PDCCH carried in coreset#1 also follows the TCI usage of coreset#1, which uses the first uplink TCI State (value), i.e., uses UL-TCI-State5 for transmission. If the base station indicates two TCI states (values), which are joint TCIs, and does not distinguish between uplink and downlink, the PDCCH resource and its scheduled PUCCH resource use the same TCI state (value indication). For example, the base station indicates TCI-State5 and TCI-State7, and is configured with CORESET #1 to use the first TCI State (value), i.e., TCI-State5; the PUCCH scheduled by PDCCH carried in CORESET #1 is also transmitted using the first TCI State, TCI-State 5. Similarly, the PUSCH transmission may also determine the TCI status (value) similarly, and will not be described again.

(2) In another implementation, if the base station indicates multiple TCI states (values), for example, two downlink TCI states (values) and two uplink TCI states, the system will predefine the association relationship between the multiple TCI states (values). For example, 1) the system predefines that a first downstream TCI state (value) is used in combination with a first upstream TCI state, and a second downstream TCI state is used in combination with a second upstream TCI state. In this case, for PDCCH, when configured to use the first downlink TCI state (valued), its scheduled PUCCH or PUSCH will be transmitted according to the first uplink TCI state (valued) associated with this first downlink TCI state. If the base station indicates two downlink TCI states and two uplink TCI states, the two states are respectively indicated as DL-TCI-State9 and DL-TCI-State23, UL-TCI-State5 and UL-TCI-State17. 2) The system predefines that the first downstream TCI State (value) is used in combination with the first upstream TCI State (value), and the second downstream TCI State (value) is used in combination with the second upstream TCI State (value), i.e. DL-TCI-State9 is associated with UL-TCI-State5, DL-TCI-State23 is associated with UL-TCI-State17. At this time, if coreset#1 is transmitted using DL-TCI-State9, PUCCH scheduled by PDCCH carried by it is transmitted using UL-TCI-State 5.

Example 9:

in this example, for "determining a beam direction corresponding to at least one resource or resource group according to the second predefined information; according to the beam direction, uplink transmission and/or downlink transmission of the determined resources or the resource groups are carried out; the second predefined information includes: at least one of the beam direction of the synchronization signal block SSB, the beam direction of the physical uplink shared channel PUSCH, or the predefined TCI state value determined when the terminal performs cell access is specifically exemplified as follows:

in a Multi-TRP (Multi transmission point) transmission scheme based on M-DCI, a base station (corresponding to the network device) configures CORESET Pool Index (control resource set pool index) parameters for a terminal. Wherein CORESET Pool Index corresponds to one TRP (transmission point) and CORESET Pool Index1 corresponds to another TRP. One MAC-CE signaling activates a set of TCI states for CORESET Pool Index0 and indicates one of them using DCI; another MAC-CE signaling activates a set of TCI states for CORESET Pool Index1 and indicates one of them using another DCI. After the base station configures the TCI state through RRC, and before the DCI indicates the TCI state, since there is no indication of the TCI state, a default beam between the UE and the TRP needs to be determined for uplink and downlink transmission.

One of the following ways may be used:

mode one: single TRP transmission is employed. For inter-cell multi-TRP transmission scenarios, only the serving cell TRP is transmitting. At this time, the downlink transmission uses the beam direction of the SSB in the serving cell access process as a default beam direction for transmission; when the uplink transmission uses the access of a serving cell, the beam direction used by the scheduled PUSCH transmission is transmitted.

For a multi-TRP transmission scenario in a cell, the configuration may be default to transmit using only one TRP corresponding to CORESET Pool Index value; for example, transmission is performed using a TRP of CORESET Pool Index0 only. The downlink transmission corresponding to CORESET Pool Index0 uses the beam direction of the SSB in the access process of the serving cell as a default beam direction for transmission; CORESET Pool Index0 (beam direction used for scheduled PUSCH transmission in serving cell access).

Mode two: multi-TRP transmission is employed. For a multi-TRP transmission scene among cells, for a serving cell, downlink transmission is carried out by using the beam direction of SSB in the access process of the serving cell as a default beam direction; when the uplink transmission uses the access of a serving cell, the beam direction used by the scheduled PUSCH transmission is transmitted. The TRP of the non-serving cell may take a predefined TCI state. One way is to use the TCI state with the smallest ID (identification) in the TCI state pool configured by RRC, or to use the TCI state corresponding to the lowest code point in the MAC-CE activation signaling.

For a multi-TRP transmission scenario within a cell, the system may predefine the transmission of two CORESET Pool Index valued corresponding TRPs. For example, the TRP corresponding to CORESET Pool Index0 uses the beam direction of the SSB in the serving cell access process as the default beam direction for downlink transmission; and when the service cell is adopted for access, uplink transmission is carried out in the beam direction used by the scheduled PUSCH transmission. A predefined TCI state is employed for the corresponding TRP of CORESET Pool Index: one way is to use the TCI state with the smallest ID in the TCI state pool configured by RRC, or to use the TCI state corresponding to the lowest code point in the MAC-CE activation signaling.

Mode three: a multi-TRP transmission is employed and a default TCI state pair is predefined by the system, which ensures that the terminal can receive both TRP transmissions simultaneously. A predefined way may be: adopting two TCI states with the minimum ID in a TCI state pool configured by RRC; or adopting two TCI states with minimum ID in TCI states activated by MAC-CE signaling; or adopting the TCI state corresponding to the lowest one or two code points in the MAC-CE activation signaling.

Example 10:

for transmission of PDSCH (physical downlink shared channel) and PUSCH and non-scheduled Type 2CG (configured grant) PUSCH, DCI is required for scheduling indication. The DCI is carried over a PDCCH (physical downlink control channel) transmitted on CORESET. The CORESET may be configured to use the TCI state indicated by the base station described in any of examples 1-8, or may be configured to not use the TCI state indicated by the base station described in examples 1-8. When the CORESET is configured to use the TCI state indicated by the base station as described in any of examples 1-8, PDSCH, PUSCH, and/or Type 2CG PUSCH may schedule transmissions for the same TCI state of CORESET as the PDCCH in which it was transmitted (i.e., PDSCH, PUSCH, and/or Type 2CG PUSCH). For example, DCI formats 0_1 and/or 0_2 transmitted in CORESET1 schedule transmission of PUSCH and CORESET1 is configured to use one of the two TCI states indicated in any of examples 1-8; the PUSCH will also use this TCI state for uplink transmission.

When the CORESET is configured to not use the TCI state indicated by the base station described in examples 1-8, PDSCH, PUSCH, and/or Type 2CG PUSCH are no longer transmitted using this CORESET same TCI state. At this time, a TCI state corresponding to CORESET Pool Index (corresponding to CORESET where the PDCCH is scheduled) may be used. For example, the CORESET corresponds to CORESET Pool Index0, and the base station indicates CORESET Pool Index the TCI state corresponding to CORESET Pool Index via MAC-CE or DCI; PDSCH, PUSCH and/or Type 2CG PUSCH all use the TCI state indicated.

Alternatively, PDSCH, PUSCH and/or Type 2CG PUSCH all use the TCI state indicated in the scheduled PDCCH. For example, PDCCH formats 1_1 and/or 1_2 in the CORESET indicate a TCI state; PDSCH, PUSCH and/or Type 2CG PUSCH scheduled by PDCCH transmitted in CORESET all use the TCI state indicated by said PDCCH formats 1_1 and/or 1_2.

Here, the (serving) cell access in the present application refers to (serving) cell access performed by a terminal, but is not limited thereto.
