The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0050] In the MAC specification, the TCI state activation / deactivation MAC CE activates up to eight joint TCI states or uplink (UL) / downlink (DL) TCI states, corresponding to eight code points in the physical layer downlink control information (DCI). Figure 2 shows a schematic diagram of the MAC CE format.

[0051] For example, the Unified TCI States Activation / Deactivation MAC CE is identified by a MAC subheader with eLCID. It has a variable size consisting of following fields:

[0052] Serving Cell ID: This field indicates the identifier of the serving cell to which the MAC CE applies. The field length is 5 bits. (Serving Cell ID: This field indicates the identity of the Serving Cell for which the MAC CE applies. The length of the field is 5 bits.) If the indicated Serving Cell is configured as part of a simultaneousU-TCI-UpdateList1, simultaneousU-TCI-UpdateList2, simultaneousU-TCI-UpdateList3 or simultaneousU-TCI-UpdateList4 as specified in TS 38.331[5], this MAC CE applies to all serving cells in the set simultaneousU-TCI-UpdateList1, simultaneousU-TCI-UpdateList2, simultaneousU-TCI-UpdateList3 or simultaneousU-TCI-UpdateList4, respectively. applies to all theServing Cells in the set simultaneousU-TCI-UpdateList1,simultaneousU-TCI-UpdateList2,simultaneousU-TCI-UpdateList3or simultaneousU-TCI-UpdateList4,respectively;)

[0053] DL-Band WidthPart (BWP) identifier: This field indicates a DL BWP for which the MAC CE applies as the codepoint of the DCI bandwidth part indicator field as specified in TS 38.212[9]. The length of the BWP ID field is 2 bits;

[0054] UL BWP ID:This field indicates a UL BWP for which the MAC CE applies as the codepoint of the DCI bandwidth part indicator field as specified in TS 38.212[9].The length of the BWP ID field is 2 bits;

[0055] P i : This field indicates whether each TCI code point has multiple TCI states or a single TCI state. i If the field is set to 1, it indicates that the i-th TCI code point includes DL TCI state and UL TCI state. i If the field is set to 0, it indicates that the i-th TCI code point includes only DL / joint TCI state or UL TCI state. The code point to which the TCI state is mapped is determined by its sequential position in all TCI state ID fields. (P i :This field indicates whether each TCI codepoint has multiple TCI states or single TCI state.If P i field is set to 1,it indicates that i thTCI codepoint includes the DL TCI state and the UL TCI state.If Pi field is set to 0,it indicates that i th TCI codepoint includes only the DL / joint TCI state or the UL TCI state.The codepoint to which a TCI state is mapped is determined by its ordinal position among all the TCI state ID fields;)

[0056] D / U: This field indicates whether the TCI state ID in the same octet is for joint / downlink or uplink TCI state. If this field is set to 1, the TCI state ID in the same octet is for joint / downlink. If this field is set to 0, the TCI state ID in the same octet is for uplink. (D / U: This field indicates whether the TCI state ID in the same octet is for joint / downlink or uplink TCI state. If this field is set to 1, the TCI state ID in the same octet is for joint / downlink. If this field is set to 0, the TCI state ID in the same octet is for uplink;)

[0057] TCI state ID: This field indicates the TCI state identified by TCI-StateId as specified in TS 38.331[5].If D / U is set to 1,7-bits length TCI state ID ieTCI-StateId as specified in TS 38.331[5]is used.If D / U is set to 0,the most significant bit of TCI state ID is considered as the reserved bit and remainder 6bits indicate the UL-TCIState-Id as specified in TS 38.331[5].The maximum number of activated TCI states is 16;

[0058] R: Reserved bit, set to 0.

[0059] The unified TCI state activated by the MAC CE typically belongs to a single TRP in a serving cell. In the Multiple-Input-Multiple-Output (MIMO) project of Release 18, a unified TCI state is proposed for activating two TRPs in a serving cell: one TRP is the serving TRP, and the other is a TRP associated with an additional PCI (called an incremental TRP).

[0060] A new MAC CE can be introduced to activate the unified TCI state of two TRPs belonging to one serving cell.

[0061] For example, for the MAC CE enhancement, it is supported that each TCI codepoint corresponds to one or both TRP(s).

[0062] For example, for MAC CE enhancement, each corresponding TRP is supported to be mapped to:

[0063] A joint TCI status, or

[0064] DL TCI state, UL TCI state, or a pair of DL and UL TCI states.

[0065] (For the MAC CE enhancement,it is supported that each corresponding TRP maps to:

[0066] -one joint TCI state, or

[0067] -a DL TCI state,an UL TCI state,or a pair of DL and UL TCI states)

[0068] For example, for sDCI based mTRP operation using unified TCI state framework, introduce the new MAC CE containing TCI state information of mTRPs.

[0069] If the signaling type of the unified TCI state configuration is configured by RRC (ieeither joint DL / UL TCI state or separate DL / UL TCI state), it applies to both TRPs.

[0070] Introduce the new field indicating if the unified TCI state of the second TRP is present or not.

[0071] In addition, on the unified TCI framework extension for S-DCI based MTRP operation, support the followings:

[0072] For a serving cell configured with joint DL / UL TCI mode, a full-set or any sub-set of {first joint TCI state, second joint TCI state} can be mapped to a TCI codepoint of the existing TCI field in a DCI format 1_1 / 1_2 by TCI state activation command(MAC-CE)

[0073] For a serving cell configured with separate DL / UL TCI mode, a full-set or any sub-set of {first DL TCI state, first UL TCI state, second DL TCI state, second UL TCI state} can be mapped to a TCI codepoint of the existing TCI field in a DCI format 1_1 / 1_2 by TCI state activation command (MAC-CE)

[0074] TCI state activation command (MAC-CE) should indicate that each joint / DL / UL TCI state mapped to a TCI codepoint is the first or second joint / DL / UL TCI state

[0075] The first / second indicated joint / DL / UL TCI state(s) is updated according to the corresponding first / second joint / DL / UL TCI state(s)mapped to the TCI codepoint received by the UE

[0076] If the UE receives a TCI code point mapped to a subset of {first joint TCI state, second joint TCI state} or {first DL TCI state, first UL TCI state, second DL TCI state, second UL TCI state}, the UE shall update the first or second indicated joint / DL / UL TCI state according to the first / second joint / DL / UL TCI state in the subset, and maintain the first or second indicated joint / DL / UL TCI state in the subset that is not updated by the received TCI code point. (If the UE receives a TCI codepoint mapped with a sub-set of{first joint TCI state,second joint TCI state}or{first DL TCI state,first UL TCI state,second DL TCI state,second UL TCI state}, the UE shall update the first / second indicated joint / DL / UL TCI state(s)according to the first / second joint / DL / UL TCI state(s)in the subset and keep other indicated first / second joint / DL / UL TCI state(s)that is not updated by the received TCI codepoint.)

[0078] S310. The first communication device receives a transmission configuration indication TCI state activation command, where the TCI state activation command is used to indicate one or more sets of TCI states.

[0079] In an embodiment of the present application, a first communication device, such as a terminal device, may receive a TCI state activation command from a second communication device, such as a network device. The TCI state activation command is used to activate multiple, for example, up to eight, TCI states, corresponding to eight code points in physical layer signaling downlink control information (DCI). The TCI state activation command may be carried in a MAC CE.

[0080] In one embodiment, a correspondence exists between a transmission reception point (TRP) and a TCI state, and the multiple sets of TCI states include a unified TCI state for multiple TRPs. For example, a unified TCI state for two TRPs belonging to a serving cell may be activated via a TCI state activation command, where one TRP is a serving TRP and the other TRP is a TRP associated with an additional PCI (also referred to as an incremental TRP). The serving TRP corresponds to one set of TCI states, and the incremental TRP corresponds to another set of TCI states.

[0081] In one embodiment, the multiple sets of TCI states include a first set of TCI states and a second set of TCI states. For example, a TCI state activation command is used to indicate two sets of TCI states, each set of TCI states including one or more TCI states. For example, a set of TCI states may include one or more of downlink and uplink TCI states, downlink TCI states, uplink TCI states, downlink or uplink TCI states, combined TCI states, and no TCI states.

[0082] In one implementation, the TCI state activation command is carried by a MAC CE sent by a second communication device, the first communication device is a terminal device, and the second communication device is a network device.

Of course, these TCI states may also be in other orders, which are not exhaustive. The order of the first set of TCI states and / or the second set of TCI states described below is similar.

[0091] In the embodiment of the present application, the first parameter may include multiple bits, which may constitute multiple values, and one value may correspond to one TCI state in the first set of TCI states.

Among them, 11 can correspond to the first downlink and uplink TCI state; 10 can correspond to the first downlink TCI state; 01 can correspond to the first uplink TCI state; 00 can correspond to the no TCI state. For example, F i It includes 3 bits, and the value of the 3 bits can be {111, 110, 101, 100, 011, 010, 001, 000}.

The above-mentioned first parameter value and its corresponding TCI state are only examples and not limitations, and can be flexibly set according to actual needs. For example, 11 may also correspond to the first downlink TCI state, 01 may also correspond to no TCI state, etc.

[0101] In one embodiment, the TCI state activation command includes a second parameter corresponding to a second set of TCI states.

[0102] In one embodiment, in the TCI state activation command, the first set of TCI states precedes the second set of TCI states. For example, in the format of a MAC CE, the first parameter precedes the second parameter.

[0112] Second downlink and uplink TCI status;

[0113] Second downlink or uplink TCI status;

[0114] No TCI status.

[0115] For example, the second parameter S in the MAC CE i It includes 2 bits, and the value of the 2 bits can be {11, 10, 01, 00}. Among them, 11 can correspond to the second downlink and uplink TCI state; 10 can correspond to the second downlink or uplink TCI state; 01 can correspond to the no TCI state. 00 can be unused. For example, S iIt includes 3 bits, and the value of the 3 bits can be {111, 110, 101, 100, 011, 010, 001, 000}. Among them, 110 can correspond to the second downlink and uplink TCI state; 101 can correspond to the second downlink or uplink TCI state; 011 can correspond to the no TCI state. i Other values ​​of may not be used. The above-mentioned second parameter value and its corresponding TCI state are only examples and not limitations, and can be flexibly set according to actual needs. For example, 11 may also correspond to the second downlink or uplink TCI state, and 01 may also correspond to the no TCI state.

[0116] In one embodiment, the second set of TCI states includes at least one of:

[0117] Second Joint TCI status;

[0118] No TCI status.

[0119] For example, the second parameter S in the MAC CE i It includes 2 bits, and the values ​​of the 2 bits can be {11, 10, 01, 00}. Among them, 11 can correspond to the first joint TCI state; 10 can correspond to the no TCI state. 01 and 00 can be unused. S in MAC CE i Includes 1 bit, and the value can be {1, 0}. Among them, 1 can correspond to the first joint TCI state; 0 can correspond to the no TCI state. For example, S i It includes 3 bits, and the value of the 3 bits can be {111, 110, 101, 100, 011, 010, 001, 000}. Among them, 110 can correspond to the first joint TCI state; 101 can correspond to the no TCI state. i Other values ​​of may not be used. The above-mentioned values ​​of the first parameter and the corresponding TCI states are only examples and not limitations, and can be flexibly set according to actual needs. For example, 11 may also correspond to the no TCI state, and 01 may also correspond to the first joint TCI state.

[0120] In one embodiment, the sequence number of the TCI state jointly indicated by the first parameter and the second parameter corresponds to a code point indicating the TCI state in physical layer signaling.

[0121] In the embodiment of the present application, multiple parameters can be used to jointly indicate multiple sets of TCI states. In one case, the TCI state activation command may include a first parameter and a second parameter. For example, in the MAC CE, the first parameter F i and the second parameter S i Jointly indicates the combination of the first set of TCI states and the second set of TCI states. Where i can represent F i and S iThe sequence number of the TCI state indicated by the joint. i and S i The i-th state of the joint indication corresponds to the i-th codepoint indicating the TCI state in the physical layer signaling. For example, the first state indicated by F1 and S1 corresponds to the first codepoint indicating the TCI state in the physical layer signaling. The eighth state indicated by F8 and S8 corresponds to the eighth codepoint indicating the TCI state in the physical layer signaling.

[0122] In the embodiments of the present application, the joint indication may also be referred to as a combined indication, a common indication, etc. The joint indication may include multiple indication modes. Several examples are described below. In the examples, the specific values ​​of the two parameters and their corresponding TCI states may change.

[0123] For example, a first parameter F1 of 11 corresponds to the first downlink and uplink TCI state in the first set of TCI states, and a second parameter S1 of 11 corresponds to the second downlink and uplink TCI state in the second set of TCI states. F1 and S1 jointly indicate the first downlink and uplink TCI state, and the second downlink and uplink TCI state. A first parameter F2 of 10 corresponds to the first downlink TCI state in the first set of TCI states, and a second parameter S2 of 10 corresponds to the second downlink TCI state in the second set of TCI states. F2 and S2 jointly indicate the first downlink TCI state, and the second downlink TCI state.

[0124] For example, a first parameter F2 of 10 corresponds to the first downlink or uplink TCI state in the first set of TCI states, and a second parameter S2 of 10 corresponds to the second downlink or uplink TCI state in the second set of TCI states. F2 and S2 jointly indicate the first downlink or uplink TCI state, and the second downlink or uplink TCI state. A first parameter F4 of 11 corresponds to the first downlink and uplink TCI state in the first set of TCI states, and a second parameter S4 of 10 corresponds to the second downlink or uplink TCI state in the second set of TCI states. F4 and S4 jointly indicate the first downlink and uplink TCI state, and the second downlink or uplink TCI state.

[0125] For another example, the first parameter F1 is 11, which corresponds to the first joint TCI state, and the second parameter S1 is 11, which corresponds to the second joint TCI state in the second set of TCI states. F1 and S1 jointly indicate the first joint TCI state and the second joint TCI state. The first parameter F2 is 11, which corresponds to the first joint TCI state, and the second parameter S2 is 10, which corresponds to the no TCI state in the second set of TCI states. F2 and S2 jointly indicate the first joint TCI state and the no TCI state. The first parameter F3 is 10, which corresponds to the no TCI state, and the second parameter S3 is 11, which corresponds to the second joint TCI state in the second set of TCI states. F2 and S2 jointly indicate the no TCI state and the second joint TCI state.

[0126] In one embodiment, the TCI state activation command includes a third parameter, and the third parameter corresponds to a combination of the first set of TCI states and the second set of TCI states.

Where i can represent T i The sequence number of the TCI state indicated. i The i-th state indicated corresponds to the i-th code point indicating the TCI state in the physical layer signaling. For example, the first state indicated by T1 corresponds to the first code point indicating the TCI state in the physical layer signaling. The eighth state indicated by T8 corresponds to the eighth code point indicating the TCI state in the physical layer signaling.

[0128] In one embodiment, the combination of the first set of TCI states and the second set of TCI states includes at least one of the following:

[0137] In the embodiment of the present application, the order of the multiple TCI states included in the combination of the first set of TCI states and the second set of TCI states is not limited. For example, the order of the combination of the first set of TCI states and the second set of TCI states can be {first downlink and uplink TCI state, second downlink and uplink TCI state, first downlink and uplink TCI state, second downlink or uplink TCI state, first downlink or uplink TCI state, second downlink and uplink TCI state, first downlink or uplink TCI state, second downlink or uplink TCI state, first downlink and uplink TCI state, first downlink or uplink TCI state, second downlink and uplink TCI state, second downlink or uplink TCI state}.

The values ​​of the above-mentioned third parameter and the corresponding TCI states are only examples and not limitations, and can be flexibly set according to actual needs. For example, 111 may correspond to the second downlink or uplink TCI state, and 000 may correspond to the first downlink and uplink TCI state and the second downlink and uplink TCI state, etc. The third parameter also includes 4 or more bits, and specific examples can be deduced and are not exhaustive.

For another example, the second downlink and uplink TCI state includes a second downlink TCI state and a second uplink TCI state. The second downlink TCI state may precede the second uplink TCI state.

[0141] In one embodiment, the downlink or uplink TCI state includes a downlink TCI state or an uplink TCI state. For example, the above-mentioned first downlink or uplink TCI state includes a first downlink TCI state or a first uplink TCI state. The first downlink or uplink TCI state may also not distinguish between uplink and downlink, for example, it may be directly expressed as the first TCI state, and then the uplink or downlink may be indicated by an indicator bit for indicating the uplink and downlink directions, such as the fifth parameter described below. For another example, the above-mentioned second downlink or uplink TCI state includes a second downlink TCI state or a second uplink TCI state. The second downlink or uplink TCI state may also not distinguish between uplink and downlink, for example, it may be directly expressed as the second TCI state, and then the uplink or downlink may be indicated by an indicator bit for indicating the uplink and downlink directions, such as the fifth parameter described below.

[0142] In one embodiment, the TCI state activation command includes a fourth parameter, and the fourth parameter corresponds to multiple sets of joint TCI states.

[0143] In one embodiment, the sequence number of the TCI state indicated by the fourth parameter corresponds to the TCI code point indicating the TCI state in the physical layer signaling. In the embodiment of the present application, multiple sets of joint TCI states can be indicated by one parameter. For example, in the MAC CE, the fourth parameter FT i Indicates the status of multiple sets of joint TCI. Among them, i can represent FT i The sequence number of the TCI state indicated. FT i The i-th state indicated corresponds to the i-th codepoint indicating the TCI state in the physical layer signaling. For example, the first state indicated by FT1 corresponds to the first codepoint indicating the TCI state in the physical layer signaling. The eighth state indicated by FT8 corresponds to the eighth codepoint indicating the TCI state in the physical layer signaling.

[0144] In one embodiment, the plurality of sets of joint TCI states include at least one of the following:

[0145] a first joint TCI state and a second joint TCI state;

[0146] First Joint TCI State;

[0147] Second joint TCI status.

[0148] In an embodiment of the present application, the order of the multiple joint TCI states included in the multiple sets of joint TCI states may not be restricted. For example, the order in the multiple sets of joint TCI states may be {first joint TCI state and second joint TCI state, first joint TCI state, second joint TCI state}. For another example, the order in the multiple sets of joint TCI states may be {first joint TCI state, first joint TCI state and second joint TCI state, second joint TCI state}. For another example, the order in the multiple sets of joint TCI states may be {first joint TCI state, second joint TCI state, first joint TCI state and second joint TCI state}. The above examples may also include a no TCI state.

[0149] In one embodiment, the fourth parameter includes 2 or more digits. For example, the fourth parameter FT i It includes 2 bits, and the 2-bit value is {11, 10, 01, 00}. Among them, 11 can correspond to the first joint TCI state and the second joint TCI state; 10 can correspond to the first joint TCI state, and 01 can correspond to the second joint TCI state. 00 can be unused or correspond to the no TCI state. For example, FT i It includes 3 bits, and the value of the 3 bits can be {111, 110, 101, 100, 011, 010, 001, 000}. Among them, 110 can correspond to the first joint TCI state and the second joint TCI; 101 can correspond to the first joint TCI state; 011 can correspond to the second joint TCI state. FT i Other values ​​of may not be used. The above-mentioned fourth parameter value and its corresponding TCI state are merely examples and not limitations and can be flexibly set according to actual needs. For example, 11 may correspond to the second combined TCI state, 01 may correspond to the first combined TCI state and the second combined TCI state, and so on. The fourth parameter also includes 4 or more bits, and specific examples can be deduced and are not exhaustive.

[0150] In one implementation, the combined TCI state indicates that one TCI state includes an uplink TCI state and a downlink TCI state.

[0151] In one embodiment, the TCI state activation command includes a fifth parameter, which is used to indicate uplink or downlink. For example, in the MAC CE, the fifth parameter may represent an indicator bit associated with the TCI state identifier (TCI state ID), such as an indicator bit before the TCI state identifier. The indicator bit may indicate uplink or downlink. For example, when the indicator bit is D / U in the MAC CE format, it may indicate uplink or downlink. The value of the indicator bit is 1 to indicate uplink, and 0 to indicate downlink. Alternatively, the value of the indicator bit is 0 to indicate uplink, and 1 to indicate downlink. For another example, when the indicator bit is R in the MAC CE format, it may not indicate uplink or downlink. The value of the indicator bit is 1 or 0 and does not indicate uplink or downlink.

[0152] In the embodiment of the present application, the fifth parameter may be combined with one or more of the first parameter, the second parameter, the third parameter, and the fourth parameter. For example, in a MAC CE, the first parameter may correspond to a first uplink or downlink TCI state, the second parameter may correspond to a second uplink or downlink TCI state, and the fifth parameter may indicate whether these TCI states are uplink or downlink. For another example, in a MAC CE, the third parameter may indicate a first uplink or downlink TCI state, or a second uplink or downlink TCI state, and the fifth parameter may indicate whether these TCI states are uplink or downlink.

[0153] The expression of parameters in the embodiment of this application is F i 、S i 、T i , FT i The above are only examples and not limitations. In actual applications, the parameter representation can be modified according to the needs. For example, the third parameter or the fourth parameter can also be expressed as F i For example, the first parameter is expressed as PA, the second parameter is expressed as PB, the third parameter is expressed as P, and so on.

[0154] In embodiments of the present application, one or more TCI states can be flexibly activated by using one or more parameters in a TCI state activation command. A TCI state can correspond to a single TRP, and multiple TCI states can correspond to multiple TRPs. For example, in a MIMO scenario, a unified TCI state can be activated for multiple TRPs.

[0203] a first joint TCI state and a second joint TCI state;

[0204] First Joint TCI State;

[0206] In one embodiment, the fourth parameter includes 2 or more bits.

[0207] In one implementation, the combined TCI state indicates that one TCI state includes an uplink TCI state and a downlink TCI state.

[0208] In one implementation, the sequence number of the TCI state indicated by the fourth parameter corresponds to a TCI code point indicating the TCI state in physical layer signaling.

[0209] In one embodiment, the downlink and uplink TCI states include a downlink TCI state and an uplink TCI state.

[0210] In one implementation, the downlink or uplink TCI state includes a downlink TCI state or an uplink TCI state.

[0211] In one embodiment, the TCI state activation command includes a fifth parameter, and the fifth parameter is used to indicate uplink or downlink.

[0212] In one implementation, the TCI state activation command is carried by a MAC CE sent by a second communication device, the first communication device is a terminal device, and the second communication device is a network device.

[0213] For a specific example of the second communication device executing the method 400 of this embodiment, reference can be made to the relevant description of the second communication device, such as the network device, in the method executed by the first communication device, which will not be repeated here for the sake of brevity.

[0214] In this embodiment of the present application, a unified TCI state is activated, which may include a joint TCI state and a downlink or uplink TCI state (DL / UL TCI state). In the MAC CE, a 2-bit parameter is used to represent the combination of DL / UL TCI states, such as {DL & UL TCI state, DL TCI state, UL TCI state, none}. The combination of the first set of TCI states and the combination of the second set of TCI states can each be represented by the above 2 bits.

[0215] If the MAC CE of the joint TCI state is designed separately, the 2-bit parameter can represent the following example combination {1 st Joint TCI state, 2 nd Joint TCI state, 1 st Joint TCI state and 2 nd Joint TCI state}.

[0216] In this embodiment of the present application, the relationship between the TCI state and the TCI state identifier (State ID) can be that the TCI state identifier is the index configured by the DL or UL BWP of the serving cell where the TCI state is located. If only the TCI state identifier is in the MAC CE, it can represent the TCI state pointed to by this index.

[0217] Example 1: The schematic block diagram of MAC CE format 1 is shown in Figure 5:

[0218] In this example, in addition to the parameter F i and S i The meanings of other parameters are the same as those in MAC CE in related technologies. i Examples of meanings include:

[0219] F i and S iThe 2 bits are used to represent 4 combinations of DL / UL TCI states, such as {DL TCI state & UL TCI state, DL TCI state, UL TCI state, none}. Among them, none means that there is no corresponding TCI state. Specifically, for example, the 2-bit values ​​corresponding to these combinations can be {11, 10, 01, 00}, for example, 11 corresponds to DL TCI state & UL TCI state, 10 corresponds to DL TCI state, 01 corresponds to UL TCI state, and 00 corresponds to none. i and S i The definition and order of the values ​​and their corresponding TCI states can vary. For example, F i and S i The 2-bit value of can be {10, 01, 00, 11}. 10 corresponds to UL TCI state, 01 corresponds to DL TCI state, 00 corresponds to DL TCI state & UL TCI state, and 11 corresponds to none. In the embodiment of the present application, other value definitions are not excluded.

[0220] F i Parameters can correspond to the first set of TCI states; S i The parameters can correspond to the second set of TCI states. i and S i All corresponding TCI status identification parameters correspond to the i-th code point in the physical layer DCI, for example, 1<=i<=8. The number of code points may also change.

[0221] For the combination of "DL TCI state & UL TCI state", the DL TCI state ID and UL TCI state ID will appear at the same time in the MAC CE format, and the order of the two TCI state IDs is fixed. For example, the DL TCI state ID always appears before the UL TCI state ID or vice versa. i and S i The parameters are set independently, so there are 16 possible combinations of the 4 combinations and the permutations between them. The combination {none, none} is invalid because it means that the first and second sets of TCI states do not appear in the MAC CE, and F i and / or S i It is used to indicate the combination of TCI state ID corresponding to a valid code point. In this format, F i and Si The position of the parameters is fixed (for example, F i and S i The order of F i and S i The TCI state IDs corresponding to the parameters are also arranged in order from low to high according to the i sequence.

[0222] For example, the values ​​of F1 and S1 are 01 and 11 respectively, which means that the combination of TCI states corresponding to the first code point is {1 st UL TCI state, 2 nd DL TCI state and UL TCI state}. Among them, 1 st UL TCI state is one of the first set of TCI states, corresponding to the first TRP, such as the service TPR; 2 nd The DL TCI state and the UL TCI state are one of the second set of TCI states, corresponding to the second TRP, such as the incremental TPR.

[0223] For the Joint TCI state, under the premise of using the same MAC CE format, F i and S i The combination that needs to be represented is {Joint TCI state, none}. In one example, F i and S i Each of them only needs 1 bit, and their values ​​are different from the UL / DL TCI state. For example, the combined TCI state can correspond to {01,00}. In this case, the two values ​​10 and 11 may be invalid. For example, when F1 is 01 and S1 is 01, the TCI state combination corresponding to the first code point is {1 st Joint TCI state, 2 nd Joint TCI state}. Among them, 1 st Joint TCI state is one of the first set of TCI states, corresponding to the first TRP such as service TPR; 2 nd Joint TCI state is one of the second set of TCI states, corresponding to the second TRP, such as incremental TPR. For example, the combination of TCI states corresponding to the first code point when F2 is 01 and S2 is 00 is {1 st Joint TCI state, none}. Among them, 1 stJoint TCI state is one of the first set of TCI states, corresponding to the first TRP such as service TPR; none is one of the second set of TCI states, corresponding to the second TRP such as incremental TPR.

[0224] Example 2: The schematic block diagram of MAC CE format 2 is shown in Figure 6:

[0225] This format can reuse the D / U bit in the MAC CE of the related art. In this case, the main difference compared with the format in Example 1 is: i and S i The corresponding TCI state combination can be {DL TCI state & UL TCI state, DL / UL TCI state, none}. DL / UL TCI State represents either DL TCI state or UL TCI state. This is because the difference between DL TCI state and UL TCI state can be reflected in the D / U bit.

[0226] For the combination of "DL TCI state and UL TCI state", for the same reason, the order between the DL TCI state and the UL TCI state does not need to be fixed.

[0227] In this format, the design of the Joint TCI state can be the same as the MAC CE format in this example, because the D / U bit can be ignored in the Joint TCI state.

[0228] For example, the values ​​of F1 and S1 are 11 and 10 respectively, which means that the combination of TCI states corresponding to the first code point is {1 st DL TCI state & UL TCI state, 2 nd DL / UL TCI state}. Among them, 1 st DL TCI state & UL TCI state is one of the first set of TCI states, corresponding to the first TRP such as the service TPR; 2 nd The DL / UL TCI state is one of the second set of TCI states, corresponding to the second TRP, such as the incremental TPR.

[0229] Example 3: The schematic block diagram of MAC CE format 3 is shown in Figure 7:

[0230] The D / U bits in this format can have the same meaning as in the previous format. In this case, F iThe 3 bits can represent the combination between the first set of TCI states and the second set of TCI states. The following are examples:

[0231] {1 st DL&UL TCI state and 2 nd DL&UL TCI state,

[0232] 1 st DL&UL TCI state and 2 nd DL / UL TCI state,

[0233] 1 st DL&UL TCI state,

[0234] 1 st DL / UL TCI state and 2nd DL&UL TCI state,

[0235] 1 st DL / UL TCI state and 2 nd DL / UL TCI state,

[0236] 1 st DL / UL TCI state,

[0237] 2 nd DL&UL TCI state,

[0238] 2 nd DL / UL TCI state,}

[0239] The DL & UL TCI state, also referred to as DL TCI state & UL TCI state, can represent a pair of a DL TCI state and a UL TCI state. The DL / UL TCI state can represent either the DL TCI state or the UL TCI state. If the D / U bit is present, the order of DL and UL in the DL & UL TCI state is not fixed.

[0240] For example, the value of F1 is 111, which means that the combination of TCI states corresponding to the first code point is {1 st DL&UL TCI state, 2 nd DL&UL TCI state}. The value of F2 is 110, which means that the combination of TCI states corresponding to the first code point is {1 st DL&UL TCI state, 2 ndDL / UL TCI state}. The value of F3 is 101, which means that the combination of TCI states corresponding to the first code point is {1 st DL&UL TCI state, none}.

[0241] The order in the combination between the first set of TCI states and the second set of TCI states and the F i The corresponding relationship of the values ​​can be adjusted at will and is not limited in the embodiments of the present application.

[0242] For the Joint TCI State, you can use the F in this format. i For example, the encoding method in MAC CE format 4 can be used to represent the joint TCI state.

[0243] Example 4: The schematic block diagram of MAC CE format 4 is shown in Figure 8:

[0244] For the combined TCI state, the first set of TCI states and the second set of TCI states can also be combined and unified. For example, {1 st Joint TCI state and 2 nd Joint TCI state, 1 st Joint TCI state, 2 nd Joint TCI state}. This way, all combinations can be expressed with just 2 bits.

[0245] Under the premise of using the same MAC CE format as MAC CE format 1 or format 2, use F i or S i The 2 bits in the MAC CE format 3 can achieve this purpose. i The 2 bits can achieve this purpose.

[0246] If the MAC CE designed for the joint TCI state adopts an independent MAC CE format instead of sharing the MAC CE format with the DL / UL TCI state, its format can be simplified as follows:

[0247] In this format, the UL BWP ID and the preceding R bit can be omitted because the Joint TCI state ID can be configured in the DL BWP. This approach saves 3 bytes of signaling overhead.

[0248] By adopting any of the MAC CE formats in the above examples, the function of activating the unified TCI state can be realized in multiple TRPs of MIMO.
