Background Art

[0002] To reduce signaling overhead, unified TCI state (Transmission Configuration Indicator state) indication has been introduced. Here, the unified TCI state indication includes joint TCI state indication and / or separate TCI state indication. Here, the joint TCI state indication specifically includes indicating that a certain TCI state is used for both uplink transmission and downlink reception at the same time, and the separate TCI state indication specifically includes indicating that a certain TCI state is used for uplink transmission or downlink reception.

[0003] However, in related technologies, there is no method for how to indicate the unified TCI state. Therefore, an indication method for the unified TCI state is urgently needed.

The embodiments described below with reference to the accompanying drawings are exemplary and are for the purpose of explaining the present disclosure and should not be understood as limiting the present disclosure.

[0019] In the information indication method provided by an embodiment of the present disclosure, a UE acquires indication information transmitted from a base station, the indication information includes at least one TCI state ID corresponding to at least one codepoint, and then, based on this indication information, the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determines that the TCI state is applied to uplink transmission and / or downlink reception. Here, specifically, the UE determines that the TCI state is applied to uplink transmission and / or downlink reception based on at least one of the first indication field in the indication information, the number of TCI state IDs corresponding to the codepoint, the ID value of the TCI state ID, the TCI state pool ID to which the TCI state ID belongs, the uplink / downlink usage information of the TCI state ID, the TCI state information of the TCI state ID, and the position of the indication information of the TCI state ID in the indication field. Thereby, the embodiment of the present disclosure provides a specific indication method for the TCI state, realizes unified TCI state indication, and reduces signaling overhead.

[0020] Hereinafter, with reference to the drawings, the information indication method, apparatus, user equipment, base station, and storage medium provided by the present disclosure will be described in detail.

[0021] FIG. 1 is a schematic flowchart of an information indication method provided by an embodiment of the present disclosure, which is applied to a UE (User Equipment), and as shown in FIG. 1, this information indication method can include the following steps.

[0022] In step 101, obtain indication information, where the indication information can include at least one TCI state ID (Index) corresponding to at least one codepoint (code point).

[0023] Note that the indication method in the embodiments of the present disclosure is applicable to any UE. The UE may refer to a device that provides voice and / or data connectivity to a user. The UE can communicate with one or more core networks via a Radio Access Network (RAN). The UE may be, for example, an Internet of Things user equipment such as a sensor device, a mobile phone (also called a "cellular" phone), and a computer with Internet of Things user equipment, or may be, for example, a fixed, portable, pocket, handheld, computer-integrated or in-vehicle device. For example, it may be a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Or, the UE may be a device of a drone. Or, the UE may be an in-vehicle device, for example, a trip computer with a wireless communication function, or may be a wireless user equipment of an external trip computer. Or, the UE may be a roadside device, for example, a street lamp, a traffic signal lamp, or other roadside devices with a wireless communication function.

[0024] In addition, in one embodiment of the present disclosure, the codepoint included in the indication information is specifically the codepoint corresponding to the TCI field included in DCI (Downlink Control Information) signaling. Also, in one embodiment of the present disclosure, one codepoint may correspond to only one TCI state ID. In another embodiment of the present disclosure, one codepoint may correspond to multiple TCI state IDs. Also, in one embodiment of the present disclosure, when one codepoint corresponds to multiple TCI state IDs, these multiple TCI state IDs may be the same. In another embodiment of the present disclosure, when one codepoint corresponds to multiple TCI state IDs, these multiple TCI state IDs may be different.

[0025] Also, in one embodiment of the present disclosure, the indication information is transmitted by the base station. The UE can obtain the indication information transmitted from the base station via MAC CE (Media Access Control Control Element) signaling.

[0026] In step 102, determine that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determine that the TCI state is applied to uplink transmission and / or downlink reception.

[0027] In one embodiment of the present disclosure, a joint TCI state specifically means that a certain TCI state is simultaneously applied to uplink transmission and downlink reception. Also, in one embodiment of the present disclosure, a joint TCI state indication specifically includes that a certain TCI state is simultaneously applied to uplink transmission and downlink reception.

[0028] In another embodiment of the present disclosure, the separate TCI state specifically means that a certain TCI state is applied to uplink transmission or downlink reception. Further, in one embodiment of the present disclosure, the separate TCI state indication specifically includes indicating only a certain TCI state for uplink transmission, indicating only a certain TCI state for downlink reception, and indicating at least two TCI states, where some TCI states are used for downlink reception and other TCI states are used for uplink transmission.

[0029] Based on this, in one embodiment of the present disclosure, the separate TCI state can specifically include a separate DL downlink TCI state (corresponding to the case of "indicating only a certain TCI state for downlink reception"), a separate UL uplink TCI state (corresponding to the case of "indicating only a certain TCI state for uplink transmission"), and a separate DL TCI state and a separate UL TCI state (corresponding to the case of "indicating at least two TCI states, where some TCI states are used for downlink reception and other TCI states are used for uplink transmission").

[0030] In one embodiment of the present disclosure, the uplink transmission may include at least one of PUCCH (Physical Uplink Control Channel) transmission, PUSCH (Physical Uplink Shared Channel) transmission, PRACH (Physical Random Access Channel) transmission, DMRS (Demodulation Reference Signal) transmission, SR (Scheduling Request) transmission, and SRS (Sounding Reference Signal) transmission.

[0031] In one embodiment of the present disclosure, the downlink reception may include at least one of PDCCH (Physical Downlink Control Channel) transmission, PDSCH (Physical Downlink Shared Channel) transmission, PBCH (Physical Broadcast Channel) transmission, SSB (Synchronization Signal Block) transmission, DMRS (Demodulation Reference Signal) transmission, CSI-RS (Channel State Information Reference Signal) transmission, PRS (Positioning Reference Signal) transmission, and TRS (Tracking Refernece Signal) transmission.

[0032] Note that all embodiments of the present disclosure are described for one TRP (Transmission Reception Point). That is, both the number and type of TCI state IDs corresponding to a codepoint correspond to one TRP. When multiple TRPs are considered, the number and / or type of TCI state IDs for different TRPs of each codepoint may be set individually. Here, the type refers to at least one of separate TCI state, joint TCI state, uplink TCI state, and downlink TCI state.

[0033] Exemplarily, in one embodiment of the present disclosure, when the base station corresponds to a first TRP and a second TRP, here, the TCI state of the TCI state ID of the first TRP corresponding to this first codepoint may be only the joint TCI state, and the TCI state of the TCI state ID of the second TRP corresponding to the first codepoint may be the separate TCI state or the joint TCI state. Or, in another embodiment of the present disclosure, the TCI state of the TCI state ID of this first TRP corresponding to the first codepoint may be only the separate TCI state, and the TCI state of the TCI state ID of the second TRP corresponding to the first codepoint may be the separate TCI state or the joint TCI state.

[0034] Here, in one embodiment of the present disclosure, the method for determining that the TCI state corresponding to at least one TCI state ID is the joint TCI state and / or the separate TCI state may include determining, based on the first indication field corresponding to each codepoint in the indication information, that the TCI state corresponding to at least one TCI state ID is the joint TCI state and / or the separate TCI state.

[0035] In another embodiment of the present disclosure, the method for determining that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state may include determining that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state based on the number of TCI state IDs corresponding to the codepoint.

[0036] Also, in one embodiment of the present disclosure, when it is determined that the TCI state of one TCI state ID corresponding to the codepoint is a separate TCI state, it is also necessary to determine that this TCI state ID corresponding to the codepoint specifically corresponds to a separate DL TCI state or a separate UL TCI state. Further, in another embodiment of the present disclosure, when the codepoint corresponds to a plurality of different TCI state IDs, it is necessary to determine the TCI state IDs corresponding to the separate DL TCI state and the TCI state IDs corresponding to the separate UL TCI state among the plurality of different TCI state IDs.

[0037] That is, when it is determined that the TCI state of the TCI state ID corresponding to the codepoint is a separate TCI state, it is also necessary to determine that this separate TCI state is specifically a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception.

[0038] Here, in one embodiment of the present disclosure, a method for determining that the separate TCI state is a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception is as follows: determining based on the ID value of at least one TCI state ID corresponding to the codepoint; determining based on the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs; determining based on the uplink / downlink usage information of at least one TCI state ID corresponding to the codepoint; determining based on the TCI state information of at least one TCI state ID corresponding to the codepoint; codepoint determining based on the position in the indication field of the indication information of at least one TCI state ID corresponding to, and may include at least one of them.

[0039] Note that in one embodiment of the present disclosure, the method for determining that the separate TCI state is specifically a separate UL TCI state and / or a separate DL TCI state may be only any one of the above methods. In another embodiment of the present disclosure, the method for determining that the separate TCI state is specifically a separate UL TCI state and / or a separate DL TCI state may be any two combinations, any three combinations, any four combinations, or all of the above five methods among the above display methods.

[0040] In addition, in one embodiment of the present disclosure, a method for determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is a separate UL TCI state and / or a separate DL TCI state based on the ID value of at least one TCI state ID corresponding to the codepoint is as follows: Based on default rules and / or configuration information, determining a range of values of TCI state IDs corresponding to TCI states for uplink transmission and a range of values of TCI state IDs corresponding to TCI states for downlink reception, and determining that the separate TCI state of each TCI state ID is a separate UL TCI state and / or a separate DL TCI state based on the range of values of TCI state IDs corresponding to TCI states for uplink transmission, the range of values of TCI state IDs corresponding to TCI states for downlink reception, and the ID value of each TCI state ID.

[0041] Here, in one embodiment of the present disclosure, this default rule may be pre-agreed by the UE and the base station based on the protocol. This configuration information may be set by the base station for the UE via RRC (Radio Resource Control) signaling.

[0042] Exemplarily, in one embodiment of the present disclosure, the default rules and / or configuration information can indicate that TCI state IDs #0 to 63 correspond to separate DL TCI states, that is, correspond to the downlink reception state, and TCI state IDs #64 to 127 correspond to separate UL TCI states, that is, correspond to the uplink transmission state.

[0043] Based on this, in one embodiment of the present disclosure, assume that a certain codepoint corresponds to two TCI state IDs including TCI state ID#0 and TCI state ID#65. In this case, based on the default rules and / or configuration information, it can be determined that TCI state ID#0 corresponds to a separate DL TCI state, that is, the downlink reception state, and TCI state ID#65 corresponds to a separate UL TCI state, that is, the uplink transmission state.

[0044] Also, in one embodiment of the present disclosure, based on the TCI state pool ID to which at least one TCI state ID corresponding to the above codepoint belongs, the method for determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is a separate UL TCI state and / or a separate DL TCI state can include the following: Pre-conventionally define a first TCI state pool ID corresponding to the TCI state for uplink transmission and a second TCI state pool ID corresponding to the TCI state for downlink reception, where the first TCI state pool ID is different from the second TCI state pool ID, and include in the indication information the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs. Then, the UE can determine that at least one TCI state ID is applied to uplink transmission and / or downlink reception based on the pre-conventionally defined first TCI state pool ID, the second TCI state pool ID, and the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint included in the indication information belongs.

[0045] Exemplarily, in one embodiment of the present disclosure, it is assumed that it is pre-agreed that pool ID #0 corresponds to the TCI state of downlink reception and pool ID #1 corresponds to the TCI state of uplink transmission. In this case, if a certain codepoint corresponds to two TCI state IDs including TCI state ID #0 and TCI state ID #1, and the indication information further includes the TCI state pool ID #0 corresponding to TCI state ID #0 and / or the TCI state pool ID #1 corresponding to TCI state ID #1, it can be determined that TCI state ID #0 corresponds to a separate DL TCI state, that is, corresponds to the downlink reception state, and TCI state ID #1 corresponds to a separate UL TCI state, that is, corresponds to the uplink transmission state.

[0046] Also, in one embodiment of the present disclosure, based on the uplink-downlink usage information of at least one TCI state ID corresponding to the above codepoint, the method for determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is a separate UL TCI state and / or a separate DL TCI state can include the following: Each TCI state ID in the indication information further corresponds to a third indication field, and this third indication field can include M bits, where M is a positive integer, and this third indication field can indicate the corresponding TCI state ID uplink-downlink usage information, where the uplink-downlink usage information includes any one of uplink transmission, downlink reception, and both uplink transmission and downlink reception. In this case, based on the third indication field corresponding to each TCI state ID, it can be determined that each TCI state ID is applied to uplink transmission and / or downlink reception.

[0047] Exemplarily, in one embodiment of the present disclosure, assuming that the third indication field includes 2 bits, here, when the value of the third indication field is 10, it is indicated that the uplink / downlink usage information of the corresponding TCI state ID is for uplink transmission, and when the value of the third indication field is 01, it is indicated that the uplink / downlink usage information of the corresponding TCI state ID is for downlink reception, and when the value of the third indication field is 11, it is indicated that the uplink / downlink usage information of the corresponding TCI state ID is for both uplink transmission and downlink reception.

[0048] Based on this, in one embodiment of the present disclosure, when a certain codepoint corresponds to two TCI state IDs including TCI state ID#0 and TCI state ID#1, and the third indication field corresponding to TCI state ID#0 is 10 and the third indication field corresponding to TCI state ID#1 is 01, it can be determined that the TCI state of TCI state ID#0 is a separate UL TCI state, that is, for uplink transmission, and the TCI state of TCI state ID#1 is a separate DL TCI state, that is, for downlink reception.

[0049] Note that when the usage information indicated by the third indication field corresponding to a certain TCI state ID is for both uplink transmission and downlink reception, it can be confirmed that the TCI state corresponding to this TCI state ID is a joint TCI state.

[0050] Also, in one embodiment of the present disclosure, a method for determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is a separate UL TCI state and / or a separate DL TCI state based on the TCI state information of at least one TCI state ID corresponding to the above codepoint can include the following: determining the TCI state information corresponding to the TCI state ID, where the TCI state information can include at least one of a reference signal type corresponding to QCL type D (Quasi Co-location type D) included in the TCI state and the use of the reference signal included in the TCI state. Based on the TCI state information corresponding to each TCI state ID, determine that the TCI state ID is applicable to uplink transmission and / or downlink reception.

[0051] Here, in one embodiment of the present disclosure, based only on the reference signal type corresponding to QCL type D, it can be determined that the separate TCI state of at least one TCI state ID corresponding to the codepoint is a separate UL TCI state and / or a separate DL TCI state.

[0052] Specifically, in one embodiment of the present disclosure, the reference signal type corresponding to QCL type D included in the TCI state can include at least one of SSB, CSI-RS, and SRS.

[0053] Also, in one embodiment of the present disclosure, a method for determining that a separate TCI state of at least one TCI state ID corresponding to a codepoint is a separate UL TCI state and / or a separate DL TCI state based on a reference signal type corresponding to QCL type D may include the following. When the reference signal type of QCL type D included in the TCI state corresponding to the TCI state ID is SSB or SRS, it is determined that the TCI state corresponding to this TCI state ID is applied to uplink transmission. When the reference signal type of QCL type D included in the TCI state corresponding to the TCI state ID is CSI-RS, it is determined that the TCI state corresponding to this TCI state ID is applied to downlink reception.

[0054] Exemplarily, in one embodiment of the present disclosure, a certain codepoint corresponds to two TCI state IDs including TCI state ID#0 and TCI state ID#1. Here, when the reference signal of QCL type D included in the TCI state corresponding to TCI state ID#0 is CSI-RS and the reference signal of QCL type D included in the TCI state corresponding to TCI state ID#1 is SRS, it can be determined that TCI state ID#0 is applied to downlink reception and TCI state ID#1 is applied to uplink transmission.

[0055] Furthermore, in one embodiment of the present disclosure, it is possible to determine that a separate TCI state of at least one TCI state ID corresponding to a codepoint is a separate UL TCI state and / or a separate DL TCI state based only on the use of the reference signal included in the TCI state.

[0056] Specifically, in one embodiment of the present disclosure, the use of the reference signal included in the TCI state can include at least one of QCL information indication, pathloss indication, and power control parameter. Here, in one embodiment of the present disclosure, the QCL can be any one of QCL Type A, QCL Type B, QCL Type C, QCL Type D, and QCL Type E.

[0057] Also, in one embodiment of the present disclosure, based on the use of the reference signal included in the TCI state, the method for determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is the separate UL TCI state and / or the separate DL TCI state can include the following. Determine that the use of the reference signal included in the TCI state corresponding to the TCI state ID is for uplink transmission or downlink reception, and further determine that the TCI state corresponding to this TCI state ID is applied to uplink transmission or downlink reception.

[0058] Exemplarily, in one embodiment of the present disclosure, a certain codepoint corresponds to one TCI state ID including TCI state ID#0. Here, when the reference signal use of the TCI state corresponding to TCI state ID#0 is pathloss and / or power control parameter indication, since the power control parameter indication is applied to uplink transmission, it can be determined that TCI state ID#0 is applied to uplink transmission.

[0059] Furthermore, in one embodiment of the present disclosure, based on the reference signal type corresponding to QCL type D included in the TCI state and the use of the reference signal included in the TCI state, it is also possible to determine that the separate TCI state of at least one TCI state ID corresponding to the codepoint is the separate UL TCI state and / or the separate DL TCI state. Here, the specific determination method can refer to the above description, and the description is omitted here in the embodiments of the present disclosure.

[0060] Also, in one embodiment of the present disclosure, based on the position in the indication field of the indication information of at least one TCI state ID corresponding to the codepoint, determining that the separate TCI state of at least one TCI state ID corresponding to the codepoint is the separate UL TCI state and / or the separate DL TCI state can include the following: Each codepoint corresponds to at least one TCI state ID indication field for storing one TCI state ID in correspondence. For example, in one embodiment of the present disclosure, the first TCI state ID indication field corresponding to the codeponit can indicate the joint TCI state or the separate DL TCI state, and the second TCI state ID indication field corresponding to the codepoint can indicate the joint TCI state or the separate UL TCI state. In another embodiment of the present disclosure, the first TCI state ID indication field corresponding to the codepoint can indicate the joint TCI state or the separate UL TCI state, and the second TCI state ID indication field corresponding to the codepoint can indicate the joint TCI state or the separate DL TCI state.

[0061] Based on this, in one embodiment of the present disclosure, by determining the TCI state ID indication field, it can be determined that the TCI state indicated by the TCI state ID in this TCI state ID indication field is a separate UL TCI state and / or a separate DL TCI state.

[0062] Exemplarily, in one embodiment of the present disclosure, assuming that the codepoint in the indication information corresponds to two TCI state ID indication fields, including a first TCI state ID indication field and a second TCI state ID indication field respectively, for example, if this first TCI state ID indication field indicates a separate DL TCI state and the second TCI state ID indication field indicates a separate UL TCI state, it is determined that the TCI state ID stored in this first TCI state ID indication field can be applied to downlink reception, and it is determined that the TCI state ID stored in this second TCI state ID indication field can be applied to uplink transmission.

[0063] In addition, in one embodiment of the present disclosure, when the TCI state ID for downlink reception is determined, RRC signaling and / or MAC CE signaling can be used to specifically indicate to which downlink transmission the TCI state ID for this downlink reception is applied. Exemplarily, in one embodiment of the present disclosure, it can be indicated that the TCI state ID for this downlink reception is applied to at least one of PDCCH, PDSCH, PBCH, SSB, DMRS, CSI-RS, PRS, and TRS. Here, in one embodiment of the present disclosure, when the TCI state ID for this downlink reception is indicated to transmit a reference signal, the use of this transmitted reference signal may be any one or more uses. Exemplarily, when the TCI state ID for this downlink reception is indicated to transmit CSI-RS, this CSI-RS may be at least one of beam sounding, for phase tracking, and channel state information sounding, etc.

[0064] Also, in one embodiment of the present disclosure, when the TCI state ID for uplink transmission is determined, it can be indicated by RRC signaling and / or MAC CE signaling which uplink transmission this TCI state ID for uplink transmission is specifically applied to. Exemplarily, in one embodiment of the present disclosure, it can be indicated that the TCI state ID for uplink transmission is applied to at least one of PUCCH, PUSCH, PRACH, SRS, DMRS, and SR. Here, in one embodiment of the present disclosure, when the TCI state ID for uplink transmission is indicated to transmit a reference signal, the use of this transmitted reference signal may be any one or more uses. Exemplarily, when the TCI state ID for uplink transmission is indicated to transmit SRS, this SRS may be at least one of beam sounding, codebook based channel state information sounding, non-codebook based channel state information sounding, for antenna switching, and positioning sounding, etc.

[0065] As described above, in the information indication method, apparatus, user equipment, base station, and storage medium provided by the embodiments of the present disclosure, the UE obtains the indication information transmitted from the base station, and the indication information includes at least one TCI state ID corresponding to at least one codepoint. Then, based on this indication information, the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determines that the TCI state is applied to uplink transmission and / or downlink reception. Here, specifically, the UE determines that the TCI state is applied to uplink transmission and / or downlink reception based on at least one of the first indication field in the indication information, the number of TCI state IDs corresponding to the codepoint, the ID value of the TCI state ID, the TCI state pool ID to which the TCI state ID belongs, the uplink / downlink usage information of the TCI state ID, the TCI state information of the TCI state ID, and the position of the indication information of the TCI state ID in the indication field. Thereby, the embodiments of the present disclosure provide a specific indication method for the TCI state, realizing unified TCI state indication and reducing signaling overhead. At the same time, the differentiated indication of joint TCI state, separate DL TCI state, separate UL TCI state, and separate DL&UL TCI state is also realized, thereby improving the reliability of DCI signaling.

[0066] Figure 2 is a schematic flowchart of an information indication method provided by another embodiment of the present disclosure, which is applicable to a UE. As shown in Figure 2, this information indication method can include the following steps.

[0067] In step 201, obtain indication information.

[0068] In step 202, based on the first indication field corresponding to each codepoint in the indication information, determine that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determine that the TCI state is applied to uplink transmission and / or downlink reception.

[0069] Here, in one embodiment of the present disclosure, the method by which the UE determines the TCI state corresponding to at least one TCI state ID based on the first indication field included in the indication information may include the following: This first indication field is: Case 1 where the indication information activates only the joint TCI state, and Case 2 where the indication information activates only the separate TCI state, and Case 3 where the indication information activates both the joint TCI state and the separate TCI state, and can indicate any one of them.

[0070] Exemplarily, in one embodiment of the present disclosure, the first indication field can include 2 bits. Also, in one embodiment of the present disclosure, when the first indication field is 10, this first indication field can indicate that the indication information received by the UE activates only the joint TCI state. When the first indication field is 01, this first indication field can indicate that the indication information received by the UE activates only the separate TCI state. When the first indication field is 11, this first indication field can indicate that the indication information received by the UE activates both the joint TCI state and the separate TCI state.

[0071] In one embodiment of the present disclosure, when this first indication field indicates that this indication information activates only the joint TCI state, this indication information specifically indicates at most one TCI state ID corresponding to each code point. Here, the TCI state corresponding to this one TCI state ID is the joint TCI state, and the joint TCI state is applicable to uplink transmission and downlink reception.

[0072] In another embodiment of the present disclosure, when the first indication field indicates that this indication information activates only the separate TCI state, this indication information specifically indicates one TCI state ID corresponding to the first code point. Here, the TCI state corresponding to this one TCI state ID is the separate DL TCI state or the separate UL TCI state. Here, the separate DL TCI state is applicable to downlink reception, and the separate UL TCI state is applicable to uplink transmission. And / or

[0073] In another embodiment of the present disclosure, this indication information indicates a plurality of TCI state IDs corresponding to the second code point, and these plurality of TCI state IDs correspond to different TCI states. Here, the first TCI state ID among these plurality of TCI state IDs is the separate DL TCI state, the second TCI state ID among these plurality of TCI state IDs is the separate UL TCI state, the separate DL TCI state is applicable to downlink reception, and the separate UL TCI state is applicable to uplink transmission.

[0074] That is, in one embodiment of the present disclosure, when the first indication field indicates that this indication information activates only the separate TCI state, this indication information can include one or more TCI state IDs respectively corresponding to the first codepoint and / or the second codepoint in the above embodiment.

[0075] In another embodiment of the present disclosure, when the first indication field indicates that this indication information activates the joint TCI state and the separate TCI state, this indication information specifically indicates one TCI state ID corresponding to the first codepoint. Here, the TCI state corresponding to this one TCI state ID is a separate DL TCI state or a separate UL TCI state. The separate DL TCI state is applied to downlink reception, and the separate UL TCI state is applied to uplink transmission. And / or

[0076] In another embodiment of the present disclosure, this indication information specifically indicates a plurality of TCI state IDs corresponding to the second codepoint, and this plurality of TCI state IDs correspond to the same TCI state. Here, the same TCI state is a joint TCI state, and the joint TCI state is applied to uplink transmission and downlink reception. And / or

[0077] In another embodiment of the present disclosure, this indication information specifically indicates a plurality of TCI state IDs corresponding to a third codepoint, and this plurality of TCI state IDs correspond to different TCI states. Here, the TCI state corresponding to the first TCI state ID among this plurality of TCI state IDs is a separate DL TCI state, and the TCI state corresponding to the second TCI state ID among this plurality of TCI state IDs is a separate UL TCI state.

[0078] That is, in one embodiment of the present disclosure, when the first indication field indicates that this indication information activates a joint TCI state and a separate TCI state, this indication information may include one or a plurality of TCI state IDs respectively corresponding to the first codepoint, and / or the second codepoint, and / or the third codepoint in the above embodiment.

[0079] Furthermore, in one embodiment of the present disclosure, when it is determined that the TCI state of one TCI state ID corresponding to a codepoint is a separate TCI state, it is also necessary to determine that this TCI state ID corresponding to the codepoint specifically corresponds to a separate DL TCI state or a separate UL TCI state. In another embodiment of the present disclosure, when a codepoint corresponds to a plurality of different TCI state IDs, it is also necessary to determine the TCI state ID corresponding to a separate DL TCI state and the TCI state ID corresponding to a separate UL TCI state among this plurality of different TCI state IDs.

[0080] That is, when it is determined that the TCI state of the TCI state ID corresponding to the codepoint is a separate TCI state, it is also necessary to determine that this separate TCI state is a separate UL TCI state specifically applied to uplink transmission and / or a separate DL TCI state applied to downlink reception.

[0081] Here, in one embodiment of the present disclosure, the method for determining that the separate TCI state is a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception is to determine based on the ID value of at least one TCI state ID corresponding to the codepoint, to determine based on the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs, to determine based on the uplink-downlink usage information of at least one TCI state ID corresponding to the codepoint, to determine based on the TCI state information of at least one TCI state ID corresponding to the codepoint, codepoint and can include at least one of determining based on the position in the indication field of the indication information of at least one TCI state ID corresponding to

[0082] In one embodiment of the present disclosure, the method for determining that the separate TCI state is specifically the separate UL TCI state and / or the separate DL TCI state may be only any one of the above methods. In another embodiment of the present disclosure, the method for determining that the separate TCI state is specifically the separate UL TCI state and / or the separate DL TCI state may be any two combinations, any three combinations, any four combinations, or all five of the above display methods among the above display methods.

[0083] As described above, in the information indication method, apparatus, user equipment, base station, and storage medium provided by the embodiments of the present disclosure, the UE obtains the indication information transmitted from the base station, and the indication information includes at least one TCI state ID corresponding to at least one codepoint. Then, based on this indication information, the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determines that the TCI state is applied to uplink transmission and / or downlink reception. Here, specifically, the UE determines that the TCI state is applied to uplink transmission and / or downlink reception based on at least one of the first indication field in the indication information, the number of TCI state IDs corresponding to the codepoint, the ID value of the TCI state ID, the TCI state pool ID to which the TCI state ID belongs, the uplink / downlink usage information of the TCI state ID, the TCI state information of the TCI state ID, and the position of the indication field of the indication information of the TCI state ID. Thereby, the embodiments of the present disclosure provide a specific indication method for the TCI state, realizing unified TCI state indication and reducing signaling overhead. At the same time, the differentiated indication of joint TCI state, separate DL TCI state, separate UL TCI state, and separate DL&UL TCI state is also realized, thereby improving the reliability of DCI signaling.

[0084] FIG. 3 is a schematic flowchart of an information indication method provided by another embodiment of the present disclosure, which is applied to a UE. As shown in FIG. 3, this information indication method can include the following steps.

[0085] In step 301, obtain indication information, where the indication information includes at least one TCI state ID corresponding to at least one code point (codepoint).

[0086] In step 302, based on the number of TCI state IDs corresponding to the codepoint, determine that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determine that the TCI state is applied to uplink transmission and / or downlink reception.

[0087] Here, in another embodiment of the present disclosure, the method by which the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state based on the number of TCI state IDs corresponding to each codepoint is Method 1 determined based on the number of TCI state IDs corresponding to the codepoint, Method 2 determined based on whether a plurality of TCI state IDs corresponding to the codepoint are the same, Method 3 determined based on whether the TCI states corresponding to a plurality of TCI state IDs corresponding to the codepoint are the same, and can include at least one of them.

[0088] Here, in one embodiment of the present disclosure, the method of determining that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state based on the number of TCI state IDs corresponding to the codepoint can include the following: In response to the number of TCI state IDs corresponding to a codepoint being one, determine that the TCI state of the one TCI state ID corresponding to the codepoint is a separate DL TCI state or a separate UL TCI state. In response to the number of TCI state IDs corresponding to a codepoint being multiple and the TCI states corresponding to the multiple TCI state IDs being the same, determine that the TCI state of the multiple TCI state IDs corresponding to the codepoint is a joint TCI state, and the joint TCI state is applied to downlink reception and uplink transmission. In response to the number of TCI state IDs corresponding to a codepoint being multiple and the TCI state IDs or TCI states corresponding to the multiple TCI state IDs being different, determine that the TCI state of the multiple TCI state IDs corresponding to the codepoint is a separate TCI state, where the TCI state corresponding to the first TCI state ID among the multiple TCI state IDs is a separate DL TCI state, and the TCI state corresponding to the second TCI state ID among the multiple TCI state IDs is a separate UL TCI state.

[0089] In addition, in one embodiment of the present disclosure, the UE can determine the number of TCI state IDs corresponding to the codepoint based on the second indication field in the indication information. Specifically, the indication information further includes at least one second indication field, and this second indication field corresponds one-to-one with the TCI state ID indication field corresponding to the codepoint. The second indication field is used to indicate whether a TCI state ID appears in one TCI state ID indication field corresponding to one codepoint. Here, when it is indicated that a TCI state ID appears in the TCI state ID indication field, it indicates that the TCI state ID is stored in this TCI state ID indication field; otherwise, it indicates that the TCI state ID is not stored. Thus, based on the number of second indication fields in which the TCI state ID appears in the indication TCI state ID indication field corresponding to the codepoint, the number of TCI state IDs corresponding to the codepoint can be determined. Specifically, when the codepoint corresponds to H second indication fields that indicate that a TCI state ID appears in the corresponding TCI state ID indication field, it is determined that this codepoint corresponds to H TCI state IDs, where H is a positive integer.

[0090] In addition, in one embodiment of the present disclosure, at least one second instruction field included in the above instruction information may correspond one-to-one with i TCI state ID instruction fields corresponding to codepoint. N is the total number of TCI state ID instruction fields corresponding to codepoint. N is a positive integer, and i is a positive integer not exceeding N. For example, i is N - 1. Here, another N - i TCI state ID instruction fields corresponding to codepoint do not have corresponding second instruction fields. That is, since the other N - i TCI state ID instruction fields necessarily indicate the occurrence of TCI state ID, the number of TCI state ID can be determined by adding N - i to the number of second instruction fields in which TCI state ID appears in the TCI state ID instruction field corresponding to codepoint. Specifically, in the i second instruction fields corresponding to codepoint, if there are H second instruction fields indicating that TCI state ID appears in the corresponding TCI state ID instruction field, it is determined that this codepoint corresponds to H + N - i TCI state IDs, and H is a positive integer.

[0091] Here, in one embodiment of the present disclosure, this second instruction field can include N bits, and N is a positive integer.

[0092] Also, in one embodiment of the present disclosure, it is assumed that when the second instruction field includes 1 bit and the value of this second instruction field is 0, it indicates that TCI state ID does not appear in the corresponding TCI state ID instruction field, and when the value of this second instruction field is 1, it indicates that TCI state ID appears in the corresponding TCI state ID instruction field.

[0093] Based on this, assume that the codepoint corresponds to two TCI state ID indication fields, namely the first TCI state ID indication field and the second TCI state ID indication field. Here, when the value of the second indication field corresponding to the first TCI state ID indication field is 0 and the value of the second indication field corresponding to the second TCI state ID indication field is 1, it indicates that the TCI state ID does not appear in the first TCI state ID indication field and appears in the second TCI state ID indication field. In this case, it is determined that this codepoint corresponds to one TCI state ID.

[0094] Alternatively, assume that the codepoint corresponds to two TCI state ID indication fields, namely the first sorted TCI state ID indication field and the second sorted TCI state ID indication field. Here, only the second TCI state ID indication field corresponds to the second indication field. Based on this, when the value of the second indication field corresponding to the second TCI state ID indication field is 0, it indicates that the TCI state ID does not appear in the second TCI state ID indication field. In this case, it is determined that the codepoint corresponds to zero second indication fields that indicate the appearance of the TCI state ID in the corresponding TCI state ID indication field. At this time, it is considered that this codepoint corresponds to 0 + 1 = 1 TCI state ID.

[0095] Note that in one embodiment of the present disclosure, when the codepoint corresponds to a plurality of TCI state ID indication fields that indicate the appearance of the TCI state ID, and the same TCI state ID appears in these plurality of TCI state ID indication fields, it is considered that this codepoint corresponds to a plurality of TCI state IDs.

[0096] Note that the determination principles of the above three methods, namely Method 1, Method 2, and Method 3, are similar. In the embodiments of the present disclosure, only "Method 1 of determining based on the number of TCI state IDs corresponding to the codepoint" will be described in detail, and the other determination methods (i.e., Method 2 and Method 3) will be described with reference to it, but will not be described here in the embodiments of the present disclosure. The above Method 1, Method 2, and Method 3 can be used alone or in combination.

[0097] Here, in one embodiment of the present disclosure, when it is determined that the TCI state of one TCI state ID corresponding to the codepoint is a separate TCI state, it is also necessary to determine that this TCI state ID corresponding to the codepoint specifically corresponds to a separate DL TCI state or a separate UL TCI state. In another embodiment of the present disclosure, when the codepoint corresponds to a plurality of different TCI state IDs, among these different TCI state IDs, it is also necessary to determine the TCI state IDs corresponding to the separate DL TCI state and the TCI state IDs corresponding to the separate UL TCI state.

[0098] That is, when it is determined that the TCI state of the TCI state ID corresponding to the codepoint is a separate TCI state, it is also necessary to determine that this separate TCI state is specifically a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception.

[0099] Here, in one embodiment of the present disclosure, the method of determining that the separate TCI state is a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception is determining based on the ID value of at least one TCI state ID corresponding to the codepoint; determining based on the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs; determining based on the uplink / downlink usage information of at least one TCI state ID corresponding to the codepoint; determining based on the TCI state information of at least one TCI state ID corresponding to the codepoint; codepoint determining based on the position in the indication field of the indication information of at least one TCI state ID corresponding to, and may include at least one of them.

[0100] In one embodiment of the present disclosure, the method for determining that the separate TCI state is specifically the separate UL TCI state and / or the separate DL TCI state may be only any one of the above methods. In another embodiment of the present disclosure, the method for determining that the separate TCI state is specifically the separate UL TCI state and / or the separate DL TCI state may be any two combinations, any three combinations, any four combinations, or all of the above five methods among the above display methods.

[0101] Note that in one embodiment of the present disclosure, when the methods for determining the separate UL TCI state applied to the uplink transmission and / or the separate DL TCI state applied to the downlink reception are different, the configuration of the indication information is also different.

[0102] Specifically, in one embodiment of the present disclosure, when determining that it is a separate UL TCI state applied to uplink transmission and / or a separate DL TCI state applied to downlink reception based on the ID value of at least one TCI state ID corresponding to the codepoint, the configuration of this indication information can specifically include at least one TCI state indication field and at least one second indication field.

[0103] Here, in one embodiment of the present disclosure, this at least one TCI state indication field can correspond one-to-one with at least one second indication field so as to indicate whether the corresponding TCI state ID indication field has appeared. Exemplarily, Table 1 is a configuration table of the indication information provided by one embodiment of the present disclosure.

Table 1

[0104] As shown in Table 1, the two second indication fields of the indication information respectively correspond one-to-one with the two TCI state ID indication fields corresponding to the codepoint. Here, the second indication field corresponding to the first TCI state ID indication field is 1, indicating that TCI state ID#0 has appeared in the first TCI state ID indication field, and the second indication field corresponding to the second TCI state ID indication field is 1, indicating that TCI state ID#1 has appeared in the second TCI state ID indication field.

[0105] In another embodiment of the present disclosure, this at least one second indication field corresponds one-to-one only with i TCI state ID indication fields corresponding to codepoints, where i is a positive integer less than or equal to N (i.e., the total number of TCI state ID indication fields corresponding to codepoints). Exemplarily, Table 2 is a configuration table of indication information provided by another embodiment of the present disclosure. [Table 2]

[0106] As shown in Table 2, the indication information includes only one second indication field, and this one second indication field corresponds only to the second TCI state ID indication field corresponding to the codepoint, indicating whether the corresponding TCI state ID indication field appears or not. Here, the second indication field corresponding to the second TCI state ID indication field is 1, indicating that TCI state ID #1 has appeared in the second TCI state ID indication field.

[0107] Furthermore, in one embodiment of the present disclosure, when determining the separate UL TCI state applied to uplink transmission and / or the separate DL TCI state applied to downlink reception based on the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs, the configuration of this indication information can specifically include at least one TCI state ID indication field, at least one second indication field, and at least one pool ID indication field.

[0108] Exemplarily, Table 3 is a configuration table of indication information provided by one embodiment of the present disclosure. [Table 3]

[0109] As shown in Table 3, the indication information includes only one second indication field, and this one second indication field corresponds only to the second TCI state ID indication field corresponding to the codepoint, and indicates whether the corresponding TCI state ID indication field appears or not. Here, the pool ID corresponding to the first TCI state ID indication field is 0, indicating that the TCI state ID #0 of the first TCI state ID indication field is applied to downlink reception, the second indication field corresponding to the second TCI state ID indication field is 1, indicating that the TCI state ID #1 appears in the second TCI state ID indication field, the pool ID corresponding to the second TCI state ID indication field is 1, and the TCI state ID #1 of the second TCI state ID indication field is applied to uplink transmission.

[0110] As described above, in the information indication method, apparatus, user equipment, base station, and storage medium provided by the embodiments of the present disclosure, the UE obtains the indication information transmitted from the base station, and the indication information includes at least one TCI state ID corresponding to at least one codepoint. Then, based on this indication information, the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determines that the TCI state is applied to uplink transmission and / or downlink reception. Here, specifically, the UE determines that the TCI state is applied to uplink transmission and / or downlink reception based on at least one of the first indication field in the indication information, the number of TCI state IDs corresponding to the codepoint, the ID value of the TCI state ID, the TCI state pool ID to which the TCI state ID belongs, the uplink / downlink usage information of the TCI state ID, the TCI state information of the TCI state ID, and the position of the indication field of the indication information of the TCI state ID. Thereby, the embodiments of the present disclosure provide a specific indication method for the TCI state, realizing unified TCI state indication and reducing signaling overhead. At the same time, the differentiated indication of joint TCI state, separate DL TCI state, separate UL TCI state, and separate DL&UL TCI state is also realized, thereby improving the reliability of DCI signaling.

[0114] Here, in one embodiment of the present disclosure, the method for determining that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state can include determining, based on a first indication field corresponding to each codepoint in the indication information, that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state.

[0115] In another embodiment of the present disclosure, the method for determining that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state can include determining, based on the number of TCI state IDs corresponding to the codepoint, that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state.

[0116] As described above, in the information indication method provided by the embodiments of the present disclosure, the UE acquires the indication information transmitted from the base station, and the indication information includes at least one TCI state ID corresponding to at least one codepoint.

Here, specifically, the UE determines that the TCI state is applied to uplink transmission and / or downlink reception based on at least one of the first indication field in the indication information, the number of TCI state IDs corresponding to the codepoint, the ID value of the TCI state ID, the TCI state pool ID to which the TCI state ID belongs, the uplink / downlink usage information of the TCI state ID, the TCI state information of the TCI state ID, and the position of the indication information of the TCI state ID in the indication field. Thereby, the embodiments of the present disclosure provide a specific indication method for the TCI state, realizing unified TCI state indication and reducing signaling overhead. At the same time, the differentiated indication of joint TCI state, separate DL TCI state, separate UL TCI state, and separate DL&UL TCI state is also realized, thereby improving the reliability of DCI signaling.

[0120] Here, in one embodiment of the present disclosure, the method for determining that the TCI state corresponding to at least one TCI state ID is applied to uplink transmission and / or downlink reception is determining based on the ID value of at least one TCI state ID corresponding to the codepoint, determining based on the TCI state pool ID to which at least one TCI state ID corresponding to the codepoint belongs, determining based on the uplink / downlink usage information of at least one TCI state ID corresponding to the codepoint, determining based on the TCI state information of at least one TCI state ID corresponding to the codepoint, codepoint and may include at least one of determining based on the position in the indication field of the indication information of at least one TCI state ID corresponding thereto.

In another embodiment of the present disclosure, the method for determining that the separate TCI state is specifically the separate UL TCI state and / or the separate DL TCI state may be any two combinations, any three combinations, any four combinations, or all five of the above display methods.

[0122] As described above, in the information indication method provided by the embodiments of the present disclosure, the UE obtains the indication information transmitted from the base station, where the indication information includes at least one TCI state ID corresponding to at least one codepoint. Then, based on this indication information, the UE determines that the TCI state corresponding to at least one TCI state ID is a joint TCI state and / or a separate TCI state, and / or determines that the TCI state is applied to uplink transmission and / or downlink reception.
