Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0115] In the 6th generation mobile networks (6G) multipath propagation (Multiple Input Multiple Output, MIMO), in order to provide higher spectrum efficiency, a large-scale antenna array in the high frequency band is introduced.

[0116] In some embodiments, especially in the working frequency range 2, since the high frequency channel attenuates quickly, in order to ensure the coverage range, communication needs to be performed based on the transmission and reception of beams.

[0117] In the process of beam-based communication, in order to ensure the communication transmission performance, beam squint is a problem that needs to be solved. Beam squint refers to the phenomenon that the signal energy cannot be fully focused within the frequency band when the antenna array realizes beam steering through the phase shifter. For example, if it is desired to focus the signal energy sent by the antenna array in a certain direction, it can be achieved by setting a certain phase compensation through the phase shifter. However, such phase compensation can usually only be applied to one frequency (such as the carrier center frequency) so that its signal energy is superimposed in the set direction. For signals other than this frequency, the direction of energy superposition is not the set direction, but has a certain offset, which is called beam squint. Beam squint causes signals of different frequency components to converge in different directions.

[0118] Exemplarily, FIG1B is a schematic diagram of a beam oblique view according to an embodiment of the present disclosure. As shown in FIG1B , in FIG1B , the beam directions of different frequencies corresponding to the precoding matrices of the four antenna ports (port A, port B, port C, and port D) are given (that is, the content represented by rays in the figure), wherein the phase corresponding to port A is (1 / 2), the phase corresponding to port B is (-j / 2), the phase corresponding to port C is (-1 / 2), and the phase corresponding to port D is (j / 2), where j is the imaginary part of the complex number, indicating that the phase is 90 degrees. In addition, the wavelength of the beam is λ. When the frequency domain resource corresponding to the antenna port is f0, the beam direction corresponding to the four antenna ports is (π / 3), and the phase corresponding to each of the four ports remains unchanged, but the corresponding frequency domain resources become In the case of , due to the problem of beam squint, the beam direction corresponding to the four antenna ports becomes (π / 4).

[0119] It is understood that in 5th generation mobile networks (5G) communication scenarios, the TCI state corresponding to each resource block (RB) and each channel or signal transmission in each bandwidth part (BWP) is the same. However, in high-frequency band transmission, beam squint may cause RBs with significantly different frequency domain resources in the same BWP to correspond to different beam directions, thereby reducing transmission performance.

[0120] Based on this, an embodiment of the present disclosure proposes a resource configuration method to solve the above problems.

[0121] FIG2 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a resource configuration method for a communication system 100, the method comprising:

[0122] Step S2101 , the network device 102 sends first indication information to the terminal 101 .

[0123] In some embodiments, the terminal 101 receives first indication information sent by the network device 102, where the first indication information is used to indicate a transmission configuration indication state (TCI state). When the TCI state (i.e., TCI state) is a plurality of TCI states, different TCI states in the plurality of TCI states correspond to different frequency domain resources.

[0124] It is understandable that, based on the above description of the beam squint phenomenon, when the phase remains unchanged, when using the same beam to send reference signals or data on different frequency domain resources, since it is the same beam and the beam direction is fixed, if the frequency domain resources differ significantly, beam squint may occur. Therefore, it can be seen that if different beams are used to send on different frequency domain resources, since the beam directions corresponding to different beams may be different, even if the transmitted frequency domain resources differ significantly, different beams can be used to send signals or data on multiple different frequency domain resources to a designated terminal, thereby reducing the impact of beam squint.

[0125] Moreover, it can be understood that the TCI state is used for beam indication. Based on this, by configuring the TCI states corresponding to different frequency domain resources, different beams can be used for transmission on different frequency domain resources, thereby reducing the impact of beam squint.

[0126] Then, how to configure the TCI states corresponding to different frequency domain resources can be achieved through the first indication information. That is, when the first indication information indicates that the TCI state is multiple TCI states, different TCI states in the multiple TCI states correspond to different frequency domain resources.

[0127] In some embodiments, the TCI state can be used to indicate at least one of the following: a reference signal resource identifier corresponding to quasi co-location (QCL); a reference signal resource port identifier corresponding to QCL; and a reference signal resource port group identifier corresponding to QCL.

[0128] In some embodiments, the frequency domain resources corresponding to the TCI state are, for example, resource block sets (RB sets). For example, the frequency domain resources are RB sets in a bandwidth part (BWP).

[0129] In some embodiments, among the multiple TCI states configured by the first indication information, the multiple TCI states meet certain conditions, including, for example, meeting at least one of the following: multiple TCI states correspond to the same control resource set pool index (Control Resource Set pool Index, CORESET pool Index); multiple TCI states correspond to the same transmission receiving point TRP; the control resource set (Control Resource Set, CORESET) corresponding to the multiple TCI states is not configured with a control resource set pool index.

[0130] It should be noted that multiple TCI states can satisfy the above conditions in communication scenarios corresponding to different types of transmission reception points (TRPs), including, for example:

[0131] In a communication scenario with a single transmission reception point (S-TRP), multiple TCI states satisfy at least one of the following: multiple TCI states correspond to the same control resource set pool index; multiple TCI states correspond to the same transmission reception point TRP; the control resource sets corresponding to multiple TCI states are not configured with a control resource set pool index.

[0132] In a communication scenario with multiple transmission receiving nodes (Multi Transmission Reception Point, M-TRP), multiple TCI states meet at least one of the following conditions: multiple TCI states correspond to the same control resource set pool index; multiple TCI states correspond to the same transmission receiving point TRP; the control resource sets corresponding to the multiple TCI states are not configured with a control resource set pool index.

[0133] Based on this, we can determine the conditions that need to be met for multiple TCI states. The specific content of the TCI states that meet the conditions also needs to be clarified.

[0134] In some embodiments, the multiple TCI states include, for example, at least one of the following: multiple joint TCI states, multiple downlink TCI states (DL TCI states), and multiple uplink TCI states (DL TCI states).

[0135] It should be noted that the multiple TCI states include multiple TCI states of the same type, such as multiple TCI states of joint type, DL type, or UL type.

[0136] The following will explain the contents of multiple TCI states from the perspectives of communication scenarios with S-TRP and communication scenarios with M-TRP:

[0137] For communication scenarios with S-TRP: For example, in communication scenarios with S-TRP, the multiple TCI states corresponding to each TRP include, for example, at least one of the following: multiple joint TCI states; multiple downlink TCI states; multiple uplink TCI states; or multiple uplink TCI states and multiple downlink TCI states. The term "multiple" includes, for example, four.

[0138] For example, the multiple TCI states corresponding to a TRP can be: 4 joint TCI states, or 4 downlink TCI states, or 4 uplink TCI states. It should be noted that the TCI state corresponding to a TRP, that is, the multiple TCI states corresponding to the multiple frequency domain resources corresponding to a TRP, and different frequency domain resources correspond to different TCI states. For example, a TRP corresponds to 4 DL TCI states, that is, these 4 DL TCI states correspond to different frequency domain resources on the downlink bandwidth part (Downlink Bandwidth Part, DL BWP); for example, a TRP corresponds to 4 UL TCI states, that is, these 4 UL TCI states correspond to different frequency domain resources on the uplink bandwidth part (Uplink Bandwidth Part, UL BWP); for example, a TRP corresponds to 4 joint TCI states, that is, these 4 joint TCI states correspond to different frequency domain resources on the UL BWP, and also correspond to different frequency domain resources on the DL BWP.

[0139] For another example, continuing with the above embodiment, the multiple TCI states corresponding to a TRP may be: in the case of two joint TCI states. For a TRP identified as #1, the frequency domain resource identifiers of its corresponding DL BWP are a# and b#, respectively. In this case, frequency domain resource a# can correspond to one joint TCI state, and frequency domain resource b# can correspond to a joint TCI state other than the joint TCI state corresponding to a#. Furthermore, the frequency domain resource identifiers of its corresponding UL BWP are c# and d#, respectively. In this case, frequency domain resource c# can correspond to one joint TCI state, and frequency domain resource d# can correspond to a joint TCI state other than the joint TCI state corresponding to c#.

[0140] For communication scenarios with M-TRP: Exemplarily, in communication scenarios with M-TRP, multiple TCI states include, for example, at least one of the following: multiple joint TCI states; multiple downlink TCI states; multiple uplink TCI states; or multiple uplink TCI states and multiple downlink TCI states. The term "multiple" includes, for example, four.

[0141] For example, the multiple TCI states corresponding to each TRP can be: 4 joint TCI states, or 4 downlink TCI states, or 4 uplink TCI states. It should be noted that the TCI state corresponding to each TRP, that is, the multiple TCI states corresponding to the multiple frequency domain resources corresponding to each TRP, and different frequency domain resources correspond to different TCI states. For example, one TRP corresponds to 4 DL TCI states, that is, these 4 DL TCI states correspond to different frequency domain resources on the DL BWP; for example, one TRP corresponds to 4 UL TCI states, that is, these 4 UL TCI states correspond to different frequency domain resources on the UL BWP; for example, one TRP corresponds to 4 joint TCI states, that is, these 4 joint TCI states correspond to different frequency domain resources on the UL BWP, and also correspond to different frequency domain resources on the DL BWP.

[0142] For another example, continuing with the above embodiment, the multiple TCI states corresponding to a TRP may be: in the case of two joint TCI states. For a TRP identified as #1, the frequency domain resource identifiers of its corresponding DL BWP are a# and b#, respectively. In this case, frequency domain resource a# can correspond to one joint TCI state, and frequency domain resource b# can correspond to a joint TCI state other than the joint TCI state corresponding to a#. Furthermore, the frequency domain resource identifiers of its corresponding UL BWP are c# and d#, respectively. In this case, frequency domain resource c# can correspond to one joint TCI state, and frequency domain resource d# can correspond to a joint TCI state other than the joint TCI state corresponding to c#.

[0143] Based on this, it is possible to determine the specific TCI states that meet the requirements in different communication scenarios. From the above embodiments, it can be seen that different TCI states correspond to different frequency domain resources. Therefore, the corresponding relationship between different TCI states and different frequency domain resources also needs to be clarified.

[0144] In some embodiments, taking different frequency domain resources in one BWP as an example, the BWP can be divided in the following manner A) to B) to obtain M different frequency domain resources, where M different frequency domain resources correspond to different TCI states, where M is an integer greater than 1.

[0145] A) Determine M different frequency domain resources based on first configuration information sent by the network device.

[0146] B) Determine M different frequency domain resources based on protocol preset rules.

[0147] Continuing with the above embodiment, the BWP is divided into M different frequency domain resources, each corresponding to a different TCI state. These M different resources, relative to the BWP, represent all frequency domain resources of the BWP.

[0148] Since M different frequency domain resources correspond to different TCI states, and, generally, one frequency domain resource corresponds to one TCI state. However, for different terminals, it may not be necessary to allocate all M frequency domain resources on the BWP to a certain terminal. For example, the frequency domain resources corresponding to the BWP may include M RB sets, of which N RB sets are determined as frequency domain resources that may be allocated to the terminal, and the remaining (MN) RB sets will not be allocated to the terminal. Therefore, the multiple TCI states indicated by the first indication information may be N different TCI states, and these N different TCI states correspond to N different frequency domain resources. That is, the multiple TCI states include N TCI states, and the N TCI states have a corresponding relationship with N different frequency domain resources in the same BWP. And N can be less than or equal to M.

[0149] Therefore, in this case, the first information can not only indicate N different TCI states, but also indicate whether the corresponding TCI state occurs in each of M different frequency domain resources. If the corresponding TCI state occurs in the M frequency domain resources, it can be understood that it is the TCI state indicated by the first information. If the corresponding TCI state does not occur in the M frequency domain resources, it can be understood that it is not the TCI state indicated by the first information.

[0150] Based on this, we can know the meaning of N different resources relative to the same BWP. How to indicate multiple different TCI states through the first indication information still needs to be determined.

[0151] For the case where M=N: In some embodiments, the first indication information includes a Medium Access Control Control Element (MAC CE) and / or downlink control information (DCI), and the MAC CE indicates N TCI states corresponding to one or more code points in the TCI field in the DCI.

[0152] For example, the code point at the lowest position is used to indicate the TCI state corresponding to the first frequency domain resource (e.g., the first RB set in the BWP). Similarly, the code point corresponding to the position next to the lowest position (i.e., the second lowest position) is used to indicate the TCI state corresponding to the second frequency domain resource (e.g., the second RB set in the BWP), until N TCI states are indicated.

[0153] For the case where M>N: In some embodiments, the first indication information includes a MAC CE and / or a DCI, wherein the first indication information includes M indication fields, each of which is used to indicate whether the TCI status corresponding to the M frequency domain resources occurs.

[0154] Based on this, it can be determined how to indicate multiple different TCI states through the first indication information.

[0155] However, the first indication information can also indicate a TCI state. For the case where the first indication information indicates a TCI state, for example, the TCI state indicated by the DCI is the TCI state corresponding to the RB corresponding to the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the terminal 101. In this case, there is a scheduling restriction on the network device 102, and the network device 102 can only schedule the RB corresponding to the TCI state (TCI state indicated by the DCI) in the BWP to communicate with the terminal. Or even if there is an RB that does not correspond to the TCI state (TCI state indicated by the DCI) in the RBs scheduled by the network device 102, the terminal 101 can only communicate on all scheduled RBs based on the TCI state (TCI state indicated by the DCI).

[0156] In some embodiments, when the TCI state is 1 TCI state, the terminal 101 satisfies at least one of the following: the terminal 101 assumes that different frequency domain resources correspond to the one TCI state; the terminal 101 does not expect the frequency domain resources corresponding to the channel of the terminal 101 to be different frequency domain resources; the terminal 101 does not expect the frequency domain resources corresponding to the reference signal resources of the terminal 101 to be different frequency domain resources; the terminal 101 expects the frequency domain resources corresponding to the channel of the terminal 101 to be the same frequency domain resources; the terminal 101 expects the frequency domain resources corresponding to the reference signal resources of the terminal to be the same frequency domain resources.

[0157] Optionally, the channel includes at least one of the following: physical downlink control channel (PDCCH); PDSCH; physical uplink control channel (PUCCH); physical uplink shared channel (PUSCH).

[0158] Optionally, the reference signal resources include: Channel Status Information-Reference Signal (CSI-RS) resources and / or Sounding Reference Signal (SRS) resources.

[0159] Based on this, it can be confirmed that when the first indication information indicates 1 TCI state, the frequency domain resources of the terminal correspond to multiple frequency domain resources, thereby ensuring the stability of the communication link.

[0160] It can be understood that through the relevant embodiments of step S2101, the indication of different TCI states corresponding to different frequency domain resources can be achieved, and then different beams can be used for communication for different frequency domain resources, thereby reducing the impact of beam squint.

[0173] In step S2102, the terminal 101 determines the TCI status.

[0174] In some embodiments, terminal 101 determines a TCI state corresponding to a channel and / or a TCI state corresponding to a reference signal resource based on the TCI state indicated by the first indication information, where the channel includes at least one of the following: PDCCH, PDSCH, PUCCH, and PUSCH. Reference signal resources include CSI-RS resources and / or SRS resources.

[0175] It is understood that when the first indication information indicates multiple TCI states, the first indication information indicates different TCI states corresponding to different frequency domain resources. The different frequency domain resources can be different frequency domain resources corresponding to channels or frequency domain resources corresponding to reference signal resources. The terminal 101 also determines the corresponding TCI state in different ways.

[0176] In some embodiments, when the channel is a PDCCH, the terminal 101 determines the TCI state corresponding to the PDCCH using at least one of the following methods a1) to c1):

[0178] b1) Determine the TCI state corresponding to the PDCCH based on the first RRC signaling, where the first RRC signaling is used to indicate that the TCI state of the CORESET is at least one TCI state among multiple TCI states, and the TCI state corresponding to the PDCCH is the TCI state of the CORESET.

[0179] c1) determining the TCI state corresponding to the PDCCH based on the second indication information, wherein the second indication information is used to indicate the TCI state of the CORESET, the TCI state corresponding to the PDCCH is the TCI state of the CORESET corresponding to the PDCCH, and the second indication information is different from the first indication information.

[0180] It is understood that in related technologies, since the entire frequency domain resources on a BWP correspond to only one TCI state for a TRP, the CORESET corresponding to the PDCCH can directly configure whether to follow this unified TCI state. However, in the disclosed embodiment, the first indication information indicates multiple TCI states. Thus, the terminal 101 needs to determine which one or more of the multiple TCI states each channel or reference signal corresponds to.

[0181] Regarding a1), it can be understood that, since the first indication information indicates different TCI states corresponding to different frequency domain resources. And the terminal can also determine the correspondence between frequency domain resources and TCI states, therefore, the terminal 101 determines the TCI state corresponding to the PDCCH based on the frequency domain resources of the CORESET corresponding to the PDCCH. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the frequency domain resources of the CORESET is used as the TCI state corresponding to the PDCCH based on the frequency domain resources indicated in the CORESET time-frequency resource configuration information. For example, the first indication information provides 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between frequency resources and TCI states. The frequency resources corresponding to the CORESET include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, so the TCI states corresponding to the CORESET are TCI #2 and TCI #3, so the TCI states corresponding to the PDCCH on the CORESET are TCI #2 and TCI #3.

[0182] In some embodiments, "frequency domain resources" and "frequency resources" can be used interchangeably.

[0183] Regarding b1), since the first RRC signaling indicates that the TCI state of the CORESET is at least one of multiple TCI states, the TCI state of the CORESET is also indicated. The first RRC signaling configured by the network device 102 indicates which one or more of the multiple TCI states the TCI state of the CORESET is. Therefore, the terminal 101 can determine the TCI state corresponding to the PDCCH based on the first RRC signaling. For example, the first indication information provides four TCI states (for example, the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4). The first RRC signaling indicates that the TCI state corresponding to the CORESET is TCI#2 and TCI#3, so the TCI state corresponding to the PDCCH on the CORESET is TCI#2 and TCI#3.

[0184] It should be noted that the TCI state indicated by the first RRC signaling may be the TCI state corresponding to the frequency domain resources corresponding to the CORESET corresponding to the PDCCH, or may not be the TCI state corresponding to the frequency domain resources corresponding to the CORESET corresponding to the PDCCH.

[0185] Optionally, in b1), the network device 102 sends a first RRC signaling to the terminal 101.

[0186] For c1), the network device 102 may separately send additional indication information (i.e., second indication information) to indicate the TCI state corresponding to the PDCCH to the terminal 101. Since the second indication information may indicate the TCI state corresponding to the CORESET. The terminal 101 may determine the CORESET corresponding to the PDCCH, and may also know the TCI state of the CORESET corresponding to the PDCCH based on the second indication information, i.e., the TCI state corresponding to the PDCCH. In this case, the network device 102 may not configure the TCI state of the CORESET corresponding to the PDCCH to be at least one TCI state among multiple TCI states. For example, four TCI states are indicated in the first indication information (e.g., the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4). The second indication information indicates that the TCI states corresponding to the CORESET are TCI#5 and TCI#6. That is, the TCI states corresponding to the PDCCH are TCI#5 and TCI#6.

[0187] Optionally, in c1), the network device 102 sends second indication information to the terminal 101.

[0188] Based on this, different TCI states corresponding to the PDCCH can be determined through at least one of methods a1) to c1).

[0189] In some embodiments, when the channel is a PDSCH, the terminal 101 determines the TCI state corresponding to the PDCCH using at least one of the following methods a2) to b2):

[0190] a2) Determine the TCI state corresponding to the PDSCH based on the frequency domain resources corresponding to the PDSCH.

[0191] b2) Determine the TCI state corresponding to the PDSCH based on the third indication information, wherein the third indication information represents the first information field in the DCI scheduling the PDSCH, and the first information field is used to indicate that the TCI state corresponding to the PDSCH is at least one TCI state among multiple TCI states.

[0192] Regarding a2), it can be understood that, since the first indication information indicates different TCI states corresponding to different frequency domain resources. And the terminal can also determine the correspondence between frequency domain resources and TCI states, therefore, the terminal 101 determines the TCI state corresponding to the PDSCH based on the frequency domain resources corresponding to the PDSCH. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the frequency domain resources of the PDSCH is used as the TCI state corresponding to the PDSCH based on the frequency domain resources of the PDSCH. For example, the first indication information gives 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between frequency resources and TCI states. The frequency resources corresponding to the PDSCH include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, so the TCI states corresponding to the PDSCH are TCI #2 and TCI #3. For b2), for the case where PDSCH is scheduled by DCI, since the third indication information represents the first information field for scheduling DCI, the first information field in the DCI can indicate that the TCI state corresponding to the PDSCH is at least one TCI state among multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the PDSCH based on the third indication information, for example, the terminal 101 determines the TCI state of the PDSCH based on which one or several of the multiple TCI states indicated in the first information field. For example, four TCI states are indicated in the first indication information (for example, the identifiers of the four TCI states are: TCI #1, TCI #2, TCI #3, and TCI #4). The first information field is used to indicate that the TCI state of the PDSCH is TCI #2 and TCI #3. Therefore, the terminal 101 can determine that the TCI state corresponding to the PDSCH is TCI#2 and TCI#3 based on the third indication information.

[0193] However, when the PDSCH is scheduled via DCI, the DCI may not include the first information field, that is, the DCI does not include an indication field indicating the TCI corresponding to the PDSCH (PDSCH scheduled by DCI format 1_0). In this case, the TCI status corresponding to the PDSCH can be determined based on the method corresponding to a2).

[0194] Optionally, in b2), the network device 102 sends third indication information to the terminal 101.

[0195] Based on this, different TCI states corresponding to the PDSCH can be determined through at least one of methods a2) to b2).

[0196] In some embodiments, when the channel is a PUSCH, the terminal 101 determines the TCI state corresponding to the PUCCH using at least one of the following methods a3) to c3):

[0197] a3) Determine the TCI state corresponding to the PUSCH based on the frequency domain resources corresponding to the PUSCH.

[0198] b3) determining the TCI state corresponding to the PUSCH based on the second RRC signaling, wherein the second RRC signaling is used to indicate that the TCI state corresponding to the PUSCH is at least one TCI state among multiple TCI states.

[0199] c3) Determine the TCI state based on the fourth indication information, wherein the fourth indication information represents the second information field in the DCI scheduling the PUSCH, and the second information field is used to indicate that the TCI state corresponding to the PUSCH is at least one TCI state among multiple TCI states.

[0200] Regarding a3), it can be understood that for a configured grant CG type 1 PUSCH, the TCI state corresponding to the PUSCH can be determined by its corresponding frequency domain part. Since the first indication information indicates that different frequency domain resources correspond to different TCI states. And the terminal can also determine the correspondence between the frequency domain resources and the TCI state. Therefore, the terminal 101 determines the TCI state corresponding to the PUSCH based on the frequency domain resources corresponding to the PUSCH. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the frequency domain resources of the PUSCH is used as the TCI state corresponding to the PUSCH based on the frequency domain resources of the PUSCH. Since the first indication information indicates different TCI states corresponding to different frequency domain resources. For example, the first indication information provides four TCI states (for example, the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4). The terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between frequency resources and TCI states. The frequency resources corresponding to the PUSCH include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, so the TCI states corresponding to the PUSCH are TCI#2 and TCI#3. Regarding b3), it can be understood that since the second RRC signaling indicates that the TCI state corresponding to the PUSCH is at least one TCI state among multiple TCI states. The second RRC signaling configured by the network device 102 indicates that the TCI state of the PUSCH is at least one of multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the PUSCH based on the second RRC signaling. For example, the first indication information specifies four TCI states (e.g., TCI#1, TCI#2, TCI#3, and TCI#4). Terminal 101 determines, based on the correspondence between frequency resources and TCI states, that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4. The second RRC signaling indicates that the TCI states corresponding to the PUSCH are TCI#2 and TCI#3.

[0201] It should be noted that the TCI state indicated by the second RRC signaling may be the TCI state of the frequency domain resources corresponding to the PUSCH, or may not be the TCI state of the frequency domain resources corresponding to the PUSCH.

[0202] Optionally, in b3), the network device 102 sends a second RRC signaling to the terminal 101.

[0203] Regarding c3), it can be understood that, for the case of scheduling PUSCH through DCI, since the second information field in the DCI can indicate that the TCI state corresponding to the PUSCH is at least one TCI state among multiple TCI states, it also indicates the correspondence between multiple TCI states and multiple frequency domain resources. Therefore, the terminal 101 can determine the TCI state corresponding to the PUSCH using the fourth indication information. For example, the terminal 101 determines the TCI state of the PUSCH based on the TCI state indicated in the second information field. For example, four TCI states are indicated in the first indication information (for example, the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4, respectively). The second information field is used to indicate that the TCI state of the PUSCH is TCI#2 and TCI#3. Therefore, the terminal 101 can determine that the TCI state corresponding to the PUSCH is TCI#2 and TCI#3 based on the fourth indication information. . However, when the PUSCH is scheduled via DCI, the DCI may not include the second information field, that is, the DCI does not include an indication field for the TCI corresponding to the PUSCH (PUSCH scheduled by DCI format 1_0). In this case, the TCI status corresponding to the PUSCH can be determined based on the method corresponding to a3).

[0204] Optionally, in c3), the network device 102 sends fourth indication information to the terminal 101.

[0205] Based on this, different TCI states corresponding to the PUSCH can be determined through at least one of methods a3) to c3).

[0206] In some embodiments, when the channel is a PUCCH, the terminal 101 determines the TCI state corresponding to the PUCCH using at least one of the following methods a4) to c4):

[0207] a4) Determine the TCI state corresponding to the PUCCH based on the frequency domain resources corresponding to the PUCCH.

[0208] b4) Determine the TCI state corresponding to the PUCCH based on the third RRC signaling, wherein the third RRC signaling is used to indicate that the TCI state corresponding to the PUCCH is at least one TCI state among multiple TCI states.

[0209] c4) Determine the TCI state corresponding to the PUCCH based on the fifth indication information, wherein the fifth indication information represents the third information field in the DCI scheduling the PUCCH, and the third information field is used to indicate that the TCI state corresponding to the PUCCH is at least one TCI state among multiple TCI states.

[0210] Regarding a4), it can be understood that for the PUCCH configured with authorization type 1, the TCI state corresponding to the PUCCH can be determined by its corresponding frequency domain part. Since different TCI states are indicated in the first indication information. And the terminal can also determine the correspondence between frequency domain resources and TCI states. Therefore, the terminal 101 determines the TCI state corresponding to the PUCCH based on the frequency domain resources corresponding to the PUCCH. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the frequency domain resources of the PUCCH is used as the TCI state corresponding to the PUCCH based on the frequency domain resources of the PUCCH. Since the first indication information indicates different TCI states corresponding to different frequency domain resources. For example, the first indication information provides four TCI states (e.g., the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4). Based on the correspondence between frequency resources and TCI states, terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4. Since the frequency resources corresponding to the PUCCH include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, the TCI states corresponding to the PUSCH are TCI#2 and TCI#3.

[0211] Regarding b4), it can be understood that since the third RRC signaling indicates that the TCI state corresponding to the PUCCH is at least one TCI state among multiple TCI states. In addition, the terminal 101 can determine the correspondence between the frequency domain resources and the TCI state. The third RRC signaling configured by the network device 102 indicates that the TCI state of the PUCCH is at least one of multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the PUCCH based on the third RRC signaling. For example, the first indication information gives 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between the frequency resources and the TCI states. The third RRC signaling indicates that the TCI states corresponding to the PUCCH are TCI#2 and TCI#3. Therefore, the terminal 101 can determine the TCI state corresponding to the PUCCH based on the third RRC signaling configured by the network device 102.

[0212] It should be noted that the TCI state indicated by the third RRC signaling may be the TCI state corresponding to the frequency domain resources corresponding to the PUCCH, or may not be the TCI state corresponding to the frequency domain resources corresponding to the PUCCH.

[0213] Regarding c4), it can be understood that, for the case where PUCCH is scheduled by DCI, since the third information field in the DCI can indicate that the TCI state corresponding to the PUCCH is at least one TCI state among multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the PUCCH based on the fifth indication information. For example, the terminal 101 determines the TCI state of the PUCCH based on the TCI state indicated in the third information field. For example, the first indication information indicates 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4). The third information field is used to indicate that the TCI state of the PUCCH is TCI#2 and TCI#3. Therefore, the terminal 101 can determine that the TCI state corresponding to the PUCCH is TCI#2 and TCI#3 based on the fifth indication information. However, in the case where PUCCH is scheduled by DCI, the DCI may not include the first information field, that is, there is no indication field indicating the TCI corresponding to the PUCCH in the DCI (PUCCH scheduled by DCI format 1_0). Then the TCI state corresponding to the PUCCH can be determined based on the method corresponding to a4).

[0214] Optionally, in c4), the network device 102 sends fifth indication information to the terminal 101.

[0215] Based on this, different TCI states corresponding to the PUCCH can be determined through at least one of methods a4) to c4).

[0216] In some embodiments, when the reference signal resource is an SRS resource, the terminal 101 determines the TCI state corresponding to the SRS resource using at least one of the following methods a5) to d5):

[0217] a5) determining a TCI state corresponding to the SRS resource based on the frequency domain resource corresponding to the SRS resource, wherein the frequency domain resource corresponding to the SRS resource is determined based on the SRS resource configuration information;

[0218] b5) determining a TCI state corresponding to the SRS resource based on a fourth RRC signaling, wherein the fourth RRC signaling is used to indicate that the TCI state corresponding to the SRS resource is at least one TCI state among multiple TCI states;

[0219] c5) determining a TCI state based on sixth indication information, where the sixth indication information is used to indicate a TCI state corresponding to the SRS resource, and the sixth indication information is different from the first indication information;

[0220] d5) Determine the TCI state corresponding to the SRS resource based on the seventh indication information, wherein the seventh indication information represents the fourth information field in the DCI for scheduling the SRS resource, and the fourth information field is used to indicate that the TCI state corresponding to the SRS resource is at least one TCI state among multiple TCI states.

[0221] Regarding a5), it can be understood that since the TCI state is indicated in the first indication information, and the terminal can also determine the correspondence between the frequency domain resources and the TCI state, the terminal 101 determines the TCI state corresponding to the SRS resource based on the frequency domain resources corresponding to the SRS resource. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the SRS resource are used as the TCI state corresponding to the SRS resource based on the frequency domain resources of the SRS resource. For example, the first indication information provides 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between the frequency resources and the TCI states. The frequency resources corresponding to the SRS resources include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, so the TCI states corresponding to the SRS resources are TCI #2 and TCI #3.

[0222] For b5), since the fourth RRC signaling indicates that the TCI state corresponding to the SRS resource is at least one TCI state among multiple TCI states. In addition, the terminal 101 can determine the correspondence between the frequency domain resources and the TCI state. The fourth RRC signaling configured by the network device 102 indicates that the TCI state of the SRS resource is at least one of multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the SRS resource based on the fourth RRC signaling. For example, the first indication information gives 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between the frequency resources and the TCI states. The fourth RRC signaling indicates that the TCI states corresponding to the SRS resources are TCI#5 and TCI#6. Therefore, the terminal 101 can determine that the TCI state corresponding to the SRS resource is TCI#5 and TCI#6 based on the fourth RRC signaling configured by the network device 102. It should be noted that the TCI state indicated by the fourth RRC signaling can be the TCI state corresponding to the frequency domain resource corresponding to the SRS resource, or can be the TCI state corresponding to the frequency domain resource other than the SRS resource.

[0223] Optionally, in b5), the network device 102 sends a fourth RRC signaling to the terminal 101.

[0224] For c5), the network device 102 may separately send another indication information (i.e., the sixth indication information) to indicate the TCI status corresponding to the SRS resource to the terminal 101. Since the sixth indication information can indicate the TCI status corresponding to the SRS resource. The terminal 101 can know the TCI status corresponding to the SRS resource based on the sixth indication information. For example, the first indication information indicates 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4). The sixth indication information indicates that the TCI status corresponding to the SRS resource is TCI#5 and TCI#6. That is, the TCI status corresponding to the SRS resource is TCI#5 and TCI#6. Optionally, in c5), the network device 102 sends the sixth indication information to the terminal 101.

[0225] For d5), for the case where SRS resources are scheduled through DCI, since the fourth information field in the DCI can indicate that the TCI state corresponding to the SRS resource is at least one TCI state among multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the SRS resource based on the seventh indication information. For example, the terminal 101 determines the TCI state corresponding to the SRS resource based on the TCI state in the fourth information field. For example, 4 TCI states are indicated in the first indication information (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4). The fourth information field is used to indicate that the TCI state of the SRS resource is TCI#2 and TCI#3. The terminal 101 can determine that the TCI state corresponding to the SRS resource is TCI#2 and TCI#3 based on the seventh indication information.

[0226] However, when SRS resources are scheduled via DCI, the DCI may not include the fourth information field, that is, the DCI does not include an indication field for the TCI corresponding to the SRS resource (SRS resources scheduled by DCI format 1_0). In this case, the TCI status corresponding to the SRS resource can be determined based on the method corresponding to step a5).

[0227] Optionally, in d5), the network device 102 sends seventh indication information to the terminal 101.

[0228] Based on this, different TCI states corresponding to SRS resources can be determined through at least one of methods a5) to d5).

[0229] In some embodiments, when the reference signal resource is a CSI-RS resource, the terminal 101 determines the TCI state corresponding to the CSI-RS resource using at least one of the following methods a6) to e6):

[0230] a6) Determine the TCI state based on the frequency domain resources corresponding to the CSI-RS resources, where the frequency domain resources corresponding to the CSI-RS resources are determined based on the CSI-RS resource configuration information.

[0231] b6) Determine the TCI state corresponding to the CSI-RS resource based on the fifth RRC signaling, wherein the fifth RRC signaling is used to indicate that the TCI state corresponding to the CSI-RS resource is at least one TCI state among multiple TCI states.

[0232] c6) Determine a TCI state corresponding to the CSI-RS resource based on eighth indication information, where the eighth indication information is used to indicate the TCI state corresponding to the CSI-RS resource, and the eighth indication information is different from the first indication information.

[0233] d6) Determine the TCI state corresponding to the CSI-RS resource based on the frequency domain resources corresponding to the CSI-RS resource, wherein the CSI-RS resource overlaps with the PDSCH, and the TCI state corresponding to the CSI-RS resource is the TCI state corresponding to the PDSCH overlapping with the CSI-RS resource.

[0234] e6) Determine the TCI state based on the ninth indication information, where the ninth indication information represents the fifth information field in the DCI for scheduling the CSI-RS resource, and the fifth information field is used to indicate that the TCI state corresponding to the CSI-RS resource is at least one TCI state among multiple TCI states.

[0235] Regarding a6), it can be understood that since the first indication information indicates the correspondence between the TCI state and the frequency domain resources, and the terminal can also determine the correspondence between the frequency domain resources and the TCI state, the terminal 101 determines the TCI state corresponding to the CSI-RS resource based on the frequency domain resources corresponding to the CSI-RS resource. For example, the terminal 101 determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the CSI-RS resource are used as the TCI state corresponding to the CSI-RS resource based on the frequency domain resources of the CSI-RS resource. For example, the first indication information provides 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between the frequency resources and the TCI states. The frequency resources corresponding to the CSI-RS resources include at least a portion of frequency resource #2 and at least a portion of frequency resource #3, so the TCI states corresponding to the CSI-RS resources are TCI #2 and TCI #3.

[0236] Regarding b6), it can be understood that since the fifth RRC signaling indicates that the TCI state corresponding to the CSI-RS resource is at least one TCI state among multiple TCI states. In addition, the terminal 101 can determine the correspondence between the frequency domain resources and the TCI state. The fifth RRC signaling configured by the network device 102 indicates that the TCI state of the CSI-RS resource is at least one of multiple TCI states. Therefore, the terminal 101 can determine the TCI state corresponding to the CSI-RS resource based on the fifth RRC signaling. For example, the first indication information gives 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4), and the terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4 based on the correspondence between the frequency resources and the TCI states. The fifth RRC signaling indicates that the TCI states corresponding to the CSI-RS resources are TCI#2 and TCI#3. Therefore, the terminal 101 may determine that the TCI states corresponding to the SRS resources are TCI#2 and TCI#3 based on the fifth RRC signaling configured by the network device 102.

[0237] It should be noted that the TCI state indicated by the fifth RRC signaling may be the TCI state corresponding to the frequency domain resources corresponding to the CSI-RS resources, or may be the TCI state corresponding to the frequency domain resources not corresponding to the CSI-RS resources.

[0238] Optionally, in b6), the network device 102 sends a fifth RRC signaling to the terminal 101.

[0239] Regarding c6), it can be understood that the network device 102 can separately send additional indication information (i.e., the eighth indication information) to indicate the TCI state corresponding to the CSI-RS resource to the terminal 101. Since the eighth indication information can indicate the TCI state corresponding to the CSI-RS resource. The terminal 101 can know the TCI state corresponding to the CSI-RS resource based on the eighth indication information. For example, the first indication information indicates 4 TCI states (for example, the identifiers of the 4 TCI states are: TCI#1, TCI#2, TCI#3 and TCI#4). The eighth indication information indicates that the TCI state corresponding to the SRS resource is TCI#5 and TCI#6. That is, the TCI state corresponding to the CSI-RS resource is TCI#5 and TCI#6.

[0240] Optionally, in c6), the network device 102 sends eighth indication information to the terminal 101.

[0241] Regarding d6), it can be understood that d6) can be understood as a special case of a6), that is, the case where the CSI-RS resource overlaps with the PDSCH. In this case, the TCI state corresponding to the PDSCH overlapping with the CSI-RS is used as the TCI state corresponding to the CSI-RS resource. The terminal 101 can determine the correspondence between the frequency domain resources and the TCI state. The terminal 101 determines the frequency domain resources where the CSI-RS overlaps with the PDSCH, and then determines which one or more of the multiple TCI states indicated in the first indication information corresponding to the TCI state of the frequency domain resources are used as the TCI state corresponding to the CSI-RS resource. For example, the first indication information provides four TCI states (e.g., the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4). Based on the correspondence between frequency resources and TCI states, terminal 101 determines that frequency resource #1 corresponds to TCI#1, frequency resource #2 corresponds to TCI#2, frequency resource #3 corresponds to TCI#3, and frequency resource #4 corresponds to TCI#4. The overlapping resources are frequency domain resources #2 and frequency domain resources #3, so the TCI states corresponding to the CSI-RS resources are TCI#2 and TCI#3.

[0242] Regarding e6), it can be understood that, for the case of scheduling CSI-RS resources through DCI, since the fifth information field in the DCI can indicate that the TCI state corresponding to the CSI-RS resource is at least one TCI state among multiple TCI states,. Therefore, the terminal 101 can determine the TCI state corresponding to the CSI-RS resource based on the ninth indication information. For example, the terminal 101 determines which one or several of the TCI states indicated by the first indication information corresponding to the CSI-RS resource based on the frequency domain resources indicated in the fifth information field. For example, four TCI states are indicated in the first indication information (for example, the identifiers of the four TCI states are: TCI#1, TCI#2, TCI#3, and TCI#4, respectively). The fifth information field is used to indicate that the TCI state of the SRS resource is TCI#2 and TCI#3. The terminal 101 can determine that the TCI state corresponding to the CSI-RS resource is TCI#2 and TCI#3 based on the ninth indication information. However, when CSI-RS resources are scheduled via DCI, the DCI may not include the fifth information field. That is, the DCI does not include an indication field for the TCI corresponding to the CSI-RS resource (CSI-RS resources scheduled by DCI format 1_0). In this case, the TCI status corresponding to the CSI-RS resource can be determined based on the method corresponding to step a6).

[0243] Optionally, in d6), the network device 102 sends ninth indication information to the terminal 101.

[0244] Based on this, different TCI states corresponding to CSI-RS resources can be determined through at least one of methods a6) to d6).

[0301] Figure 5 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a resource configuration method, which includes:

[0302] Step S5101: Send first indication information.

[0303] In some embodiments, the first indication information is used to indicate a transmission configuration indication TCI state. When the TCI state is multiple TCI states, different TCI states in the multiple TCI states correspond to different frequency domain resources.

[0304] The optional implementation of step S5101 can refer to the optional implementation of step S2101 and step S2102 in Figure 2, as well as other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0305] In some embodiments, the above method may also include the methods described in the above embodiments such as the communication system side, the terminal side, and the network device side, which will not be repeated here.

[0306] In some embodiments, the embodiments of the present disclosure also propose a resource configuration method, which reduces signaling overhead and improves transmission performance by configuring the TCI state for a resource block set (RB set), with different RB sets corresponding to different TCI states, as well as a corresponding RB set allocation method and a method for determining the TCI state corresponding to each channel or reference signal.

[0307] In some embodiments, first indication information is received, where the first indication information is used to indicate at least one TCI state. If there are multiple TCI states, the multiple TCI states correspond to different frequency domain resources.

[0308] It should be noted that the TCI state here is not a TCI state in the narrow sense, but simply means that the same TCI state corresponds to the frequency domain resources of the terminal. This TCI state can be the TCI state corresponding to S-TRP and / or M-TRP communication scenarios.

[0309] In the case of multiple TCI states:

[0310] In some embodiments, in an S-TRP communication scenario, different frequency domain resources (e.g., frequency domain resources corresponding to a TRP) may correspond to different uplink TCI states, and different frequency domain resources may also correspond to different downlink TCI states. In this case, the TCI state may include at least one of the following: one joint TCI state, one downlink TCI state, one uplink TCI state, one downlink TCI state, and one uplink TCI state.

[0311] In some embodiments, in the case of an M-TRP communication scenario, different TRPs (e.g., frequency domain resources used by different TRPs) correspond to different TCI states. It is understandable that in this scenario, if PDSCH is scheduled, then the TCI state corresponds to the RB set corresponding to the PDSCH, and the TCI states corresponding to other RB sets in the downlink BWP do not need to be considered. In this case, the TCI state can include at least one of the following: 2 joint TCI states, 1 downlink TCI state, 1 uplink TCI state, one uplink TCI state, and one downlink TCI state.

[0312] In some embodiments, the first indication information may indicate TCI status of different frequency bands (eg, different frequency domain resources) on a BWP.

[0313] It is understandable that how to divide a BWP to obtain different frequency bands (for example, to obtain different frequency domain resources) can be achieved in the following ways:

[0314] 1) Based on the base station configuration, the configuration information is sent to the terminal.

[0315] 2) Based on protocol regulations, for example, the RB index included in each RB set is specified.

[0316] The mapping relationship between different frequency domain parts and different TCI states (a mapping relationship between N frequency domain parts and N TCI states, where N is an integer greater than or equal to 1) may include at least one of the following:

[0317] a) The first indication information must indicate N TCI states.

[0318] b) The first indication information includes M TCI states corresponding to M frequency domain parts of N frequency domain parts, where M is an integer less than or equal to N.

[0319] For a), for example, the first indication information includes MAC CE and / or DCI, and the MAC CE indicates N TCI states corresponding to at least one codepoint in the TCI field in the DCI, where the lowest codepoint corresponds to the TCI state of the first RB set, and so on.

[0320] For b), for example, the first indication information includes MAC CE and / or DCI. The MAC CE indicates M TCI states corresponding to at least one codepoint in the TCI field of the DCI, where M corresponding to each codepoint may be different and M is less than or equal to N.

[0321] For another example, when M is less than N, N indication fields may be included, each of which indicates whether the Nth TCI state is present. The mapping relationship between the N TCI states and the N frequency domain parts is the same as in a).

[0322] When 1 TCI status is indicated:

[0323] For example, the TCI state indicated by the DCI is the TCI state corresponding to the RBs corresponding to the PDSCH scheduled by the terminal. This requires the base station to implement scheduling restrictions, that is, the base station only schedules RBs within a BWP that have the same TCI state for the terminal. Therefore, in this case, the terminal does not expect the RBs scheduled by the base station to have different TCI states. Even if the TCI states of these RBs may be different, the terminal only receives them based on the TCI state indicated by the DCI.

[0324] In some embodiments, the terminal determines the TCI state corresponding to the reference signal resource and / or the channel based on the reference signal resource and / or the channel.

[0325] In some embodiments, the channel includes at least one of the following: PDCCH, PUCCH, PDSCH, PUSCH.

[0326] It should be noted that the TCI state corresponding to the channel can also be referred to as the TCI state corresponding to the demodulation reference signal resource corresponding to the channel. Therefore, the above embodiment can also be understood as the terminal based on the TCI state corresponding to the reference signal resource and / or the TCI state corresponding to the channel.

[0327] In this case, the reference signal resources may include at least one of the following: reference signal resources corresponding to the CORESET corresponding to the PDCCH; reference signal resources corresponding to the PDSCH (e.g., DMRS resources); reference signal resources corresponding to the PUSCH (e.g., DMRS resources); reference signal resources corresponding to the PUCCH (e.g., DMRS resources); sounding reference signal SRS resources; channel state information reference signal CSI-RS resources.

[0328] The TCI status determination method corresponding to the CORESET corresponding to the PDCCH is as follows:

[0329] It should be noted that, in the related art, CORESET can directly configure whether to follow a unified TCI state because the first indication information on a BWP only configures one TCI state.

[0330] In the embodiment of the present disclosure, if the first indication information indicates multiple TCI states, and different TCI states correspond to different frequency domain parts, the terminal may determine the TCI state corresponding to the CORESET corresponding to the PDCCH (hereinafter referred to as the TCI state of the CORESET) by any one of the following methods (a1 to c1):

[0331] a1) The base station RRC configures the CORESET to follow a unified TCI state. For example, the terminal determines which frequency domain part to follow based on the frequency domain resource corresponding to the CORESET (indicated in the CORESET time-frequency resource configuration information).

[0332] b1) The base station RRC configures the unified TCI state of the frequency domain part that the CORESET follows.

[0333] c1) The base station does not configure the CORESET to follow a unified TCI state, and uses separate TCI state indication information different from the first indication information to indicate the TCI state of the CORESET, that is, to indicate the TCI state of the frequency domain part corresponding to the CORESET.

[0334] The TCI status corresponding to PDSCH is determined as follows:

[0335] The terminal may determine the TCI state corresponding to the PDSCH (hereinafter referred to as the TCI state of the PDSCH) in any of the following ways (a2 to b2):

[0336] a2) The terminal determines the TCI state corresponding to the PDSCH based on the frequency domain part corresponding to the PDSCH.
