Description

[0001] This application is a divisional application of the Chinese application with application number 201880002595.0 filed on December 25, 2018, and invention name “Data transmission method, base station, user equipment and storage medium”. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a method, a base station, and a user equipment for indicating a beam for data transmission. Background Art

[0003] In NR (New Radio), when the communication frequency band is in FR (Frequency Range) 2, due to the large path loss of high-frequency communication, in order to ensure coverage and resist path loss, data transmission based on beam is usually required. FR2 refers to a high frequency band with a frequency greater than 6 GHz. For example, for a beam-based reception process, the base station uses signaling to indicate the TCI (Transmission Configuration Indication) state of type D, thereby informing the user equipment of the receiving beam to be used for reception. Each TCI state corresponds to an RS (Reference Signal) identifier, which can be either a non-zero power CSI-RS (Channel State Information Reference Signal) or an SSB (Synchronization Signal Block).

[0004] In the related technology, the base station only indicates one beam direction through signaling. For example, in the reception process of PDSCH (Physical Downlink Shared Channel), different TBs (Transport Blocks) are sent by the same panel of the same TRP (Transmission Reception Point), so the TCI states used by different TBs are also the same, that is, the base station informs the user equipment to use the same receiving beam to receive these TBs.

[0005] However, in the future, MIMO (Multiple-Input Multiple-Output) needs to support data transmission based on multiple TRPs or multiple antenna panels, that is, the base station needs to use multiple transmitting beam directions to send data, and correspondingly, the user equipment needs to use multiple receiving beams to receive data. Then the signaling used in the related technology to indicate a receiving beam direction will no longer be applicable to future evolution. For this reason, in cases where different TBs are sent by different TRPs or panels, how to design new signaling so that data transmission between the base station and the user equipment can be achieved through multiple beams has become a problem that needs to be urgently solved by those skilled in the art.

[0089] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0090] Figure 1 is a schematic diagram showing an implementation environment involved in a method for instructing a beam to perform data transmission according to an exemplary embodiment. Figure 1 As shown, the implementation environment includes a base station 101 and a user equipment 102, and the base station 101 and the user equipment 102 are connected via a communication network.

[0091] For the beam-based reception process, the TCI state is used to inform the user equipment 102 that when receiving PDCCH (Physical Downlink Control Channel) / PDSCH, specifically which receiving beam to use as the same SSB or CSI-RS sent by the receiving base station 101. Among them, the base station 101 indicates the receiving beam used by the user equipment 102 when receiving the TB transmitted in the PDSCH through the TCI field in the DCI signaling. In the related art, the base station 101 only indicates one receiving beam direction through DCI signaling. For example, for two TBs of a PDSCH, since they are sent by the same panel of the same TRP, the TCI states corresponding to the two are also the same. Taking the two TBs as TB1 and TB2 as an example, the corresponding DCI signaling can be as follows:

[0092] For transport block 1:

[0093] -Modulation and coding scheme–5bits

[0094] -New data indicator–1 bit

[0095] -Redundancy version–2 bits

[0096] For transport block 2:

[0097] -Modulation and coding scheme–5bits

[0098] -New data indicator–1 bit

[0099] -Redundancy version–2 bits

[0100] …

[0101] -Transmission configuration indication–0bit if higher layer parametertci-PresentInDCI is not enabled; otherwise 3bits.

[0102] As can be seen from the above DCI signaling, TB1 and TB2 correspond to the same TCI state, that is, base station 101 notifies user equipment 102 to use the same receive beam to receive these two TBs. Furthermore, to clarify how base station 101 specifically instructs user equipment 102 to use a receive beam, the following describes the PDSCH reception process as an example.

[0103] 1. The base station 101 generates RRC signaling and uses the RRC signaling to indicate multiple TCI states.

[0104] The number of multiple TCI states may be up to 64 or up to 128, which is not specifically limited in the embodiments of the present disclosure.

[0105] 2. The base station 101 generates MAC signaling, and then uses the MAC signaling to indicate activation of some TCI states in the RRC signaling.

[0106] The number of partial TCI states may be 8, which is also not specifically limited in the embodiments of the present disclosure. In one possible implementation, when the number of TCI states included in the RRC signaling is less than 8, the base station 101 may not need to generate MAC signaling.

[0107] 3. The base station 101 generates DCI signaling and then uses the DCI signaling to indicate one of the multiple TCI states activated by the MAC signaling for the user equipment 102 to use to receive the PDSCH. That is, the base station 101 tells the user equipment 102 to use one receive beam to receive all TBs contained in the PDSCH.

[0108] 4. The base station 101 sends DCI signaling to the user equipment 102. The DCI signaling instructs the user equipment 102 to use the receiving beam used when receiving the RS corresponding to the RS identifier included in the TCI state when receiving the PDSCH. See the example in Table 1 below for details.

[0109] Table 1

[0110]

[0111] The above description is for a single receive beam direction. However, in the future, MIMO will need to support data transmission based on multiple TRPs or multiple panels. That is, the base station 101 needs to use multiple transmit beams to transmit data, and correspondingly, the user equipment 102 needs to use multiple receive beams to receive data. Therefore, how to indicate the TCI status becomes a problem to be solved in the embodiments of the present disclosure. The following embodiments will explain in detail how to implement data transmission between the base station 101 and the user equipment 102 using multiple beams.

[0112] Figure 2 FIG. 1 is a flow chart showing a method for instructing a beam to perform data transmission according to an exemplary embodiment. Figure 2 As shown, the method is applied to a base station and includes the following steps.

[0113] In step 201, the base station generates signaling for indicating at least two receiving beams of the user equipment, where the signaling includes TCI status of multiple TBs, where the multiple TBs are sent by at least two panels, where the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment.

[0114] In step 202, the base station sends the signaling to the user equipment, so that the user equipment determines a receiving beam for receiving each TB among the multiple TBs according to the signaling, and uses the determined receiving beam to receive each TB.

[0115] The method provided by the embodiment of the present disclosure is that during data transmission, the base station can send signaling to the user equipment to indicate at least two receiving beams, where the signaling includes the TCI status of multiple TBs, and the multiple TBs are sent by at least two panels, wherein the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment. In this way, after receiving the signaling, the user equipment can determine the receiving beam for receiving each TB in the multiple TBs according to the signaling, and use the determined receiving beam to receive each TB. The embodiment of the present disclosure designs new signaling, which enables the user equipment to use multiple receiving beams to receive data when the base station uses multiple transmitting beam directions to send data. This data transmission method can be applicable to data transmission based on multiple TRPs or multiple panels, making it possible to transmit data between the base station and the user equipment through multiple beams.

[0118] The base station generates MAC signaling, where the MAC signaling is used to instruct activation of M TCI states in each of the TCI state subgroups.

[0120] Generating, by the base station, first DCI signaling, where the first DCI signaling includes at least two TCI fields;

[0121] The multiple TBs correspond to the at least two TCI fields, and one TCI field is used to indicate the TCI status of one or at least two TBs in the multiple TBs;

[0122] The first DCI signaling is used to indicate one TCI state in every M TCI states.

[0123] In a possible implementation manner, the base station generates signaling for indicating at least two receive beams of the user equipment, including:

[0124] Generating, by the base station, second DCI signaling, where the second DCI signaling includes a TCI field;

[0125] The multiple TBs correspond to the one TCI field, and some bits of the one TCI field are used to indicate the TCI status of one or at least two TBs in the multiple TBs;

[0126] The second DCI signaling is used to indicate one TCI state in every M TCI states.

[0127] In a possible implementation, the method further includes:

[0128] The base station generates at least two RRC signalings, each of the at least two RRC signalings indicating a TCI state group, each of the TCI state groups including a plurality of TCI states, and each of the at least two panels corresponding to a TCI state group;

[0129] The base station generates at least two MAC signalings, each of the MAC signalings being used to instruct activation of N TCI states in one of the TCI state groups.

[0130] In a possible implementation manner, the base station generates signaling for indicating at least two receive beams of the user equipment, including:

[0131] Generating, by the base station, first DCI signaling, where the first DCI signaling includes at least two TCI fields;

[0132] The multiple TBs correspond to the at least two TCI fields, and one TCI field is used to indicate the TCI status of one or at least two TBs in the multiple TBs;

[0133] The first DCI signaling is used to indicate one TCI state in every N TCI states.

[0134] In a possible implementation manner, the base station generates signaling for indicating at least two receive beams of the user equipment, including:

[0135] Generating, by the base station, second DCI signaling, where the second DCI signaling includes a TCI field;

[0136] The multiple TBs correspond to the one TCI field, and some bits of the one TCI field are used to indicate the TCI status of one or at least two TBs in the multiple TBs;

[0137] The second DCI signaling is used to indicate one TCI state in every N TCI states.

[0138] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present disclosure, and will not be described in detail here.

[0139] Figure 3 FIG. 1 is a flow chart showing a method for instructing a beam to perform data transmission according to an exemplary embodiment. Figure 3 As shown, the method is applied to user equipment and includes the following steps.

[0140] In step 301, the user equipment receives signaling sent by the base station to indicate at least two receiving beams of the user equipment, where the signaling includes TCI status of multiple TBs, where the multiple TBs are sent by at least two panels, where the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment.

[0141] In step 302, the user equipment determines a receiving beam for receiving each TB in the multiple TBs according to the signaling, and uses the determined receiving beam to receive each TB.

[0142] The method provided by the embodiment of the present disclosure is that during data transmission, the base station can send signaling to the user equipment to indicate at least two receiving beams, where the signaling includes the TCI status of multiple TBs, and the multiple TBs are sent by at least two panels, wherein the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment. In this way, after receiving the signaling, the user equipment can determine the receiving beam for receiving each TB in the multiple TBs according to the signaling, and use the determined receiving beam to receive each TB. The embodiment of the present disclosure designs new signaling, which enables the user equipment to use multiple receiving beams to receive data when the base station uses multiple transmitting beam directions to send data. This data transmission method can be applicable to data transmission based on multiple TRPs or multiple panels, making it possible to transmit data between the base station and the user equipment through multiple beams.

[0143] Figure 4 FIG. 1 is a flow chart showing a method for instructing a beam to perform data transmission according to an exemplary embodiment. Figure 4 As shown, the interaction subjects are the base station and the user equipment, and the following steps are included.

[0144] In step 401, a base station generates RRC signaling, where the RRC signaling is used to indicate a TCI state group, where multiple TCI states included in the TCI state group are divided into at least two TCI state subgroups.

[0145] Each of the at least two panels for transmitting multiple TBs corresponds to a TCI state subgroup. For example, the multiple TBs transmitted are TBs transmitted via PDSCH, which is not specifically limited in the present embodiment.

[0146] In an embodiment of the present disclosure, at least two panels are different panels from the same TRP or panels from different TRPs, so that the base station uses multiple beam directions for data transmission. For example, for example, the number of TBs to be sent is 3. In one possible implementation, two of the TBs are sent using the same panel, and the other TB is sent using another panel, and these two panels can be different panels from the same TRP or panels from two TRPs respectively. Among them, the user equipment also needs to use different receiving beams to receive the TBs sent by different panels, so each panel in the at least two panels corresponds to a TCI state subgroup. In another possible implementation, each TB can also be sent using a different panel, and the three panels can be different panels from the same TRP or panels from three TRPs respectively.

[0147] For this step, all candidate TCI states corresponding to multiple panels are uniformly indicated through one RRC signaling.

[0148] Taking the transmission of two TBs as an example, if the base station uses one transmit beam to transmit and RRC signaling indicates 64 TCI states, then for the case of using two transmit beams, the number of TCI states indicated by RRC signaling can be no less than 64 and no more than 128, forming a TCI state group. In this TCI state group, the first X TCI states correspond to one panel, forming a TCI state subgroup, and the last Y TCI states correspond to another panel, forming another TCI state subgroup. Accordingly, the TCI state group can be as follows:

[0149] TCI#0

[0150] TCI#1

[0151] …

[0152] TCI#X-1

[0153] TCI#X

[0154] …

[0155] TCI#X+Y-1

[0156] As described above, the X+Y TCI states contained in the TCI state group are divided into two TCI state subgroups: TCI#0 through TCI#X-1 form one TCI state subgroup, and TCI#X through TCI#X+Y-1 form another TCI state subgroup. For example, assuming both X and Y are 64, TCI#0 through TCI#63 form one TCI state subgroup, corresponding to one panel; and TCI#64 through TCI#127 form another TCI state subgroup, corresponding to another panel.

[0157] In step 402, the base station generates MAC signaling, where the MAC signaling is used to instruct activation of M TCI states in each TCI state subgroup.

[0158] For this step, the activation of the TCI state is also uniformly indicated through a MAC signaling.

[0159] Among them, the value of M is a positive integer, for example, the value of M can be 8, or the value of M can be different for different TCI status subgroups, for example, for TCI status subgroup #1, the value of M is 8, and for TCI status subgroup #2, the value of M is 6. The embodiments of the present disclosure do not make specific limitations on this.

[0160] Continuing with the example of sending two TBs, if the PDSCH transmission process uses one transmit beam for data transmission, and MAC signaling is used to indicate the activation of 8 of the 64 TCI states indicated by RRC signaling, then for the case of using two transmit beams, MAC signaling can indicate the activation of 16 of the X+Y TCI states indicated by RRC signaling, and these 16 TCI states cannot come from the same TCI state subgroup. For example, 8 of them are from one TCI state subgroup, and the other 8 are from another TCI state subgroup. Accordingly, the MAC signaling used to indicate the activation of the TCI state needs to occupy X+Y bits.

[0161] In addition, the MAC CE (Control Element) also needs to indicate the serving cell ID, BWP (Bandwidth Part) ID, etc.

[0162] In summary, the activated TCI states indicated by MAC signaling must also come from each TCI state subgroup. For example, when two TRPs send multiple TBs, if each TRP has only one panel, all the activated TCI states indicated by MAC signaling cannot correspond to only one TRP, because the DCI signaling sent by the base station to the user equipment needs to indicate at least two beam directions, and for this case, one TRP only corresponds to one beam direction at a time. If two TRPs send multiple TBs, but each TRP has at least two panels, all the activated TCI states indicated by MAC signaling may correspond to one TRP, but to different panels of the TRP, so that subsequent DCI signaling can indicate at least two beam directions, each beam direction corresponding to one panel.

[0163] In step 403, the base station generates a first DCI signaling, which includes at least two TCI domains. The multiple TBs sent by at least two panels correspond to the at least two TCI domains. One TCI domain is used to indicate the TCI status of one or at least two TBs among the multiple TBs. The first DCI signaling is used to indicate one TCI status in every M TCI states.

[0164] Among them, the first DCI signaling is also referred to in this article as signaling for indicating at least two receiving beams of the user equipment. As mentioned above, the first DCI signaling includes TCI states of multiple TBs, and these TCI states are all activated by MAC signaling indication.

[0165] In the disclosed embodiments, the number of TCI fields included in DCI signaling is no less than 2 and no greater than the number of transmitted TBs. For example, assuming three TBs are transmitted, two of which are transmitted using the same panel, while the other TB is transmitted using a different panel, then the two TBs transmitted using the same panel correspond to one TCI field, and the other TB corresponds to another TCI field.

[0166] Taking two TBs each corresponding to a TCI domain as an example, the first DCI signaling may be as follows:

[0167] For transport block1:

[0168] -Modulation and coding scheme–5bits

[0169] -New data indicator–1 bit

[0170] -Redundancy version–2 bits

[0171] -Transmission configuration indication–0bit ifhigher layer parametertci-PresentInDCI is not enabled; otherwise 3bits.

[0172] For transport block 2:

[0173] -Modulation and coding scheme–5bits

[0174] -New data indicator–1 bit

[0175] -Redundancy version–2 bits

[0176] -Transmission configuration indication–0bit if higher layer parametertci-PresentInDCI is not enabled; otherwise 3bits.

[0177] …

[0178] In step 404, the base station sends first DCI signaling to the user equipment.

[0179] In step 405, the user equipment determines a receiving beam for receiving each TB in the multiple TBs according to the first DCI signaling, and uses the determined receiving beam to receive each TB.

[0180] Among them, the DCI signaling received by the user equipment includes the TCI status of multiple TBs, and the TCI status includes the RS identifier (also known as RS ID or RS index). The user equipment determines the corresponding RS based on the RS identifier in the TCI status, and then uses the receiving beam of the corresponding RS to receive the corresponding TB.

[0181] In the above process, we take two panels, such as panel#1 and panel#2, sending multiple TBs as an example:

[0182] 1. RRC signaling provides TCI state subgroup #1 and TCI state subgroup #2, where TCI state subgroup #1 corresponds to the X candidate TCI states used when panel #1 sends TB, and TCI state subgroup #2 corresponds to the Y candidate TCI states used when panel #2 sends TB.

[0183] 2. MAC signaling specifies the M activated TCI states in TCI state subgroup #1 and TCI state subgroup #2, respectively. The lower X bits of the MAC signaling are used to activate M TCI states out of the X candidate TCI states in TCI state subgroup #1; the upper Y bits of the MAC signaling are used to activate M TCI states out of the Y candidate TCI states in TCI state subgroup #2.

[0184] 3. The first DCI signaling gives one of the M TCI states activated by the MAC signaling, where the first TCI field in the first DCI signaling is used to activate one of the M TCI states activated by the lower X bits of the MAC signaling; the second TCI field in the first DCI signaling is used to activate one of the M TCI states activated by the upper Y bits of the MAC signaling.

[0185] In this way, the user equipment can obtain the accurate TCI status of each TB sent by each panel according to the DCI-MAC-RRC signaling, thereby obtaining an accurate receiving beam.

[0186] In one possible implementation, Figure 5 As mentioned above, the above steps 403 to 405 may also be replaced by the following steps 406 to 408.

[0187] In step 406, the base station generates a second DCI signaling, which includes a TCI field. Multiple TBs sent by at least two panels correspond to one TCI field, and some bits of a TCI field are used to indicate the TCI status of one or at least two TBs among the multiple TBs. The second DCI signaling is used to indicate one TCI state in every M TCI states.

[0188] The above step 403 sets multiple TCI domains in the first DCI signaling, and indicates the TCI status of multiple TBs through at least two TCI domains. In a possible implementation method, the embodiment of the present disclosure also supports the second DCI signaling to uniformly indicate the TCI status of multiple TBs through one TCI domain.

[0189] It should be noted that some of the bits in the TCI field are used to indicate the TCI status of one or at least two TBs among the multiple TBs. For example, in the case of sending two TBs, one TB may correspond to the first A bit of the TCI field, and the other TB may correspond to the remaining B bits of the TCI field. The values of A and B may be the same or different, and this is not specifically limited in the present embodiment.

[0190] In addition, in the case of using one TCI field, compared with the one TCI field in step 403, the number of bits of the TCI field will increase.

[0191] In step 407, the base station sends second DCI signaling to the user equipment.

[0192] In step 408, the user equipment determines a receiving beam for receiving each TB in the plurality of TBs according to the second DCI signaling, and uses the determined receiving beam to receive each TB.

[0193] In the above process, we take two panels, such as panel#1 and panel#2, sending multiple TBs as an example:

[0194] 1. RRC signaling provides TCI state subgroup #1 and TCI state subgroup #2, where TCI state subgroup #1 corresponds to the X candidate TCI states used when panel #1 sends TB, and TCI state subgroup #2 corresponds to the Y candidate TCI states used when panel #2 sends TB.

[0195] 2. MAC signaling specifies the M activated TCI states in TCI state subgroup #1 and TCI state subgroup #2, respectively. The lower X bits of the MAC signaling are used to activate M TCI states out of the X candidate TCI states in TCI state subgroup #1; the upper Y bits of the MAC signaling are used to activate M TCI states out of the Y candidate TCI states in TCI state subgroup #2.

[0196] 3. The second DCI signaling gives one of the M TCI states activated by the MAC signaling, where the lower A bit of the TCI field in the second DCI signaling is used to activate one of the M TCI states activated by the lower X bits of the MAC signaling; the upper B bit of the TCI field in the second DCI signaling is used to activate one of the M TCI states activated by the upper Y bits of the MAC signaling.

[0197] In this way, the user equipment can obtain the accurate TCI status of each TB sent by each panel according to the DCI-MAC-RRC signaling, thereby obtaining an accurate receiving beam.

[0198] The method provided by the embodiment of the present disclosure is that during data transmission, the base station can send signaling to the user equipment to indicate at least two receiving beams, where the signaling includes the TCI status of multiple TBs, and the multiple TBs are sent by at least two panels, wherein the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment. In this way, after receiving the signaling, the user equipment can determine the receiving beam for receiving each TB in the multiple TBs according to the signaling, and use the determined receiving beam to receive each TB. The embodiment of the present disclosure designs new signaling, which enables the user equipment to use multiple receiving beams to receive data when the base station uses multiple transmitting beam directions to send data. This data transmission method can be applicable to data transmission based on multiple TRPs or multiple panels, making it possible to transmit data between the base station and the user equipment through multiple beams.

[0199] Figure 6 FIG. 1 is a flow chart showing a method for instructing a beam to perform data transmission according to an exemplary embodiment. Figure 6 As shown, the interaction subjects are the base station and the user equipment, and the following steps are included.

[0200] In step 601, the base station generates at least two RRC signalings, each of the at least two RRC signalings indicates a TCI state group, and each TCI state group includes multiple TCI states.

[0201] In addition to indicating the TCI state set through one RRC signaling as shown in step 401 above, in one possible implementation, the embodiments of the present disclosure also support indicating the TCI state set through at least two RRC signalings. Accordingly, each of the at least two panels used to transmit multiple TBs corresponds to a TCI state group. Exemplarily, the multiple TBs transmitted may be TBs transmitted by PDSCH. The at least two panels are different panels from the same TRP or panels from different TRPs, so that the base station can use multiple beam directions for data transmission.

[0202] The base station uses different panels to send TBs, and the user equipment also needs to use different receiving beams to receive them. Therefore, each panel in at least two panels corresponds to a TCI status group.

[0203] Taking the transmission of two TBs as an example, two RRC signaling messages are generated for the case of using two transmit beams. Each RRC signaling message includes a TCI state group. The TCI state group can be as follows:

[0204] An RRC signaling contains TCI state group 1:

[0205] TCI#0

[0206] TCI#1

[0207] …

[0208] TCI#X-1

[0209] Another RRC signaling includes TCI state group 2:

[0210] TCI#0

[0211] TCI#1

[0212] …

[0213] TCI#Y-1

[0214] As described above, the first TCI state group includes X TCI states, corresponding to one panel; the second TCI state group includes Y TCI states, corresponding to another panel. For example, assuming both X and Y are 64, one TCI state group includes 64 TCI states, TCI#0 through TCI#63, corresponding to one panel; the other TCI state group also includes 64 TCI states, TCI#0 through TCI#63, corresponding to another panel.

[0215] It should be noted that the two independent TCI status groups may be sent to the user equipment at different times using different RRC signaling, or may be sent to the user equipment simultaneously using the same RRC signaling.

[0216] In step 602, the base station generates at least two MAC signalings, each MAC signaling being used to instruct activation of N TCI states in a TCI state group.

[0217] In the case of using at least two RRC signalings to indicate the TCI state set, the embodiment of the present disclosure also indicates the activation of the TCI state through at least two MAC signalings.

[0218] The value of N is a positive integer, such as 8, which is not specifically limited in the present embodiment. The value of N may also be different for different panels. It should be noted that the values of N and M may be the same or different, which is also not specifically limited in the present embodiment.

[0219] Continuing with the example of sending two TBs, if the PDSCH transmission process uses one transmit beam for data transmission, and MAC signaling is used to indicate the activation of 8 of the 64 TCI states indicated by the RRC signaling, then for the case of using two transmit beams for transmission, two MAC signalings are required to indicate the activation of the TCI state. In other words, two MAC signalings are required for this case, one of which is used to indicate the activation of 8 TCI states in one TCI state group, occupying X bits; the other MAC signaling is used to indicate the activation of 8 TCI states in another TCI state group, occupying Y bits.

[0220] In addition, the two MACCEs also need to indicate the serving cell ID, BWP ID, TRP ID, etc. respectively, which is not specifically limited in the embodiment of the present disclosure.

[0221] In summary, each TCI state activated by MAC signaling indication must also come from each TCI state group.

[0222] It should be noted that the two MAC signalings may be sent to the user equipment at different times, or may be combined into one MAC signaling and sent to the user equipment at the same time.

[0223] In step 603, the base station generates a first DCI signaling, which includes at least two TCI domains. The multiple TBs sent by at least two panels correspond to the at least two TCI domains. One TCI domain is used to indicate the TCI status of one or at least two TBs among the multiple TBs. The first DCI signaling is used to indicate one TCI status in every N TCI states.

[0224] This step is similar to the above step 403 and will not be repeated here.

[0225] In step 604, the base station sends first DCI signaling to the user equipment.

[0226] In step 605, the user equipment determines a receiving beam for receiving each TB in the multiple TBs according to the first DCI signaling, and uses the determined receiving beam to receive each TB.

[0227] In the above process, we take two panels, such as panel#1 and panel#2, sending multiple TBs as an example:

[0228] 1. RRC signaling #1 gives TCI state group #1, and RRC signaling #2 gives TCI state group #2, where TCI state group #1 corresponds to the X candidate TCI states used when panel #1 sends TB, and TCI state group #2 corresponds to the Y candidate TCI states used when panel #2 sends TB.

[0229] 2. MAC signaling #1 gives the N activated TCI states in TCI state group #1, and MAC signaling #2 gives the N activated TCI states in TCI state group #2.

[0230] 3. The first DCI signaling gives one of the N TCI states activated by the MAC signaling, where the first TCI field in the first DCI signaling is used to activate one of the N TCI states activated by MAC signaling #1; the second TCI field in the first DCI signaling is used to activate one of the N TCI states activated by MAC signaling #2.

[0231] In this way, the user equipment can obtain the accurate TCI status of each TB sent by each panel according to the DCI-MAC-RRC signaling, thereby obtaining an accurate receiving beam.

[0232] In one possible implementation, Figure 7 As mentioned above, the above steps 603 to 605 may also be replaced by the following steps 606 to 608.

[0233] In step 606, the base station generates a second DCI signaling, which includes a TCI field. Multiple TBs sent by at least two panels correspond to one TCI field, and some bits of a TCI field are used to indicate the TCI status of one or at least two TBs among the multiple TBs. The second DCI signaling is used to indicate a TCI status in every N TCI states.

[0234] This step is similar to the above step 406 and will not be repeated here.

[0235] In step 607, the base station sends second DCI signaling to the user equipment.

[0236] In step 608, the user equipment determines a receiving beam for receiving each TB in the plurality of TBs according to the second DCI signaling, and uses the determined receiving beam to receive each TB.

[0237] In the above process, we take two panels, such as panel#1 and panel#2, sending multiple TBs as an example:

[0238] 1. RRC signaling #1 gives TCI state group #1, and RRC signaling #2 gives TCI state group #2, where TCI state group #1 corresponds to the X candidate TCI states used when panel #1 sends TB, and TCI state group #2 corresponds to the Y candidate TCI states used when panel #2 sends TB.

[0239] 2. MAC signaling #1 gives the N activated TCI states in TCI state group #1, and MAC signaling #2 gives the N activated TCI states in TCI state group #2.

[0240] 3. The second DCI signaling gives one of the N TCI states activated by the MAC signaling, where the lower A bit of the TCI field in the second DCI signaling is used to activate one of the N TCI states activated by MAC signaling #1; the upper B bit of the TCI field in the second DCI signaling is used to activate one of the N TCI states activated by MAC signaling #2.

[0241] In this way, the user equipment can obtain the accurate TCI status of each TB sent by each panel according to the DCI-MAC-RRC signaling, thereby obtaining an accurate receiving beam.

[0242] The method provided by the embodiment of the present disclosure is that during data transmission, the base station can send signaling to the user equipment to indicate at least two receiving beams, where the signaling includes the TCI status of multiple TBs, and the multiple TBs are sent by at least two panels, wherein the at least two panels are different panels from the same TRP or panels from different TRPs, and the multiple TBs correspond to at least two receiving beams of the user equipment. In this way, after receiving the signaling, the user equipment can determine the receiving beam for receiving each TB in the multiple TBs according to the signaling, and use the determined receiving beam to receive each TB. The embodiment of the present disclosure designs new signaling, which enables the user equipment to use multiple receiving beams to receive data when the base station uses multiple transmitting beam directions to send data. This data transmission method can be applicable to data transmission based on multiple TRPs or multiple panels, making it possible to transmit data between the base station and the user equipment through multiple beams.

[0243] In summary, the above two embodiments explain in detail the data transmission between the base station and the user equipment through multiple beams. That is, the embodiment of the present disclosure makes it possible to transmit data between the base station and the user equipment through multiple beams by designing signaling to indicate multiple beams. This data transmission method can support data transmission based on multiple TRPs or multiple panels, is suitable for future evolution, and improves communication robustness. In detail, the embodiment of the present disclosure realizes: 1. The base station can schedule the transmission of multiple TBs through one DCI signaling, and multiple TBs can be sent using at least two panels, that is, multiple TBs can correspond to at least two TCI states, rather than multiple TBs corresponding to one TCI state; 2. One DCI signaling can jointly indicate the TCI states of multiple TBs through one TCI field; 3. One DCI signaling can independently indicate the TCI states of multiple TBs through at least two TCI fields; 4. Multiple TBs can be sent by at least two panels, and at least two panels are different panels from the same TRP or panels from different TRPs, thereby realizing multi-beam transmission.

[0270] Regarding the apparatus in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0271] Figure 11 1 is a block diagram of a user device according to an exemplary embodiment. For example, the user device 1100 may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.
