[0031] To better understand the method for determining the transmission setting instruction state disclosed in the embodiments of this disclosure, a communication system applicable to the embodiments of this disclosure will be described below.

[0032] Referring to Figure 1, Figure 1 shows the architecture of a communication system provided by an embodiment of the present application. The communication system may include one network device and one terminal device, but is not limited thereto. The number and configuration of devices shown in Figure 1 are merely examples and do not constitute limitations of the embodiment of the present application. In actual applications, it may include two or more network devices and two or more terminal devices.

[0034] In the embodiments of this application, the network device 11 is an entity for transmitting and receiving signals on the network side. For example, the network device 11 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access point in a wireless fidelity (WiFi) system.

[0036] The communication systems described in the embodiments of this application are provided to more clearly illustrate the technical solutions of the embodiments of this application and do not limit the technical solutions provided by the embodiments of this application. As those skilled in the art will see, with the evolution of system architectures and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are similarly applicable to similar technical problems.

[0037] This disclosure provides a method for determining the TCI state based on settings for the channel and / or signal when multiple sets of TCI states are indicated via a single DCI, in order to maintain a consistent understanding of TCI state usage between the terminal device and the network device and to ensure the reliability of transmission. This ensures a consistent understanding of TCI state usage between the terminal device and the network device and guarantees the reliability of transmission.

[0038] In this disclosure, the method for determining the transmission setting instruction state provided by any one embodiment can be performed individually, or in combination with possible implementations in other embodiments, or in combination with any technical proposal of the related technology.

[0039] Referring to Figure 2, which is a flowchart of a method for determining a transmission setting instruction state provided by an embodiment of the present disclosure. The method is performed by a terminal device. As shown in Figure 2, the method may include, but is not limited to, the following steps: step 201, receiving first instruction information, the first instruction information is used to indicate at least two sets of transmission setting instruction (TCI) states.

[0040] A set of TCI states refers to one TCI state or a pair of TCI states. For example, a set of TCI states may be one joint TCI state (or DL ​​or jointTCIstate), one independent downlink (DL) TCI state, or one independent uplink (UL) TCI state; or one independent DL TCI state and one independent UL TCI state, and the disclosure is not limited thereto.

[0041] Selectively, the first instruction information may be a medium access control layer (MAC) control element (CE), i.e., at least two sets of TCI states associated with a single codepoint are activated via the MAC CE.

[0042] Selectively, the first instruction information may further include MAC CE and DCI. That is, first, MAC CE directly activates at least one set of TCI states, each associated with multiple codepoints, and DCI indicates one of those codepoints, which is associated with at least two sets of TCI states.

[0043] Step 202: Based on the settings for the channel and / or signal, determine the TCI state for the transmission of the channel and / or signal.

[0044] The channel includes at least one of the following: a physical downlink control channel (PDCCH), a physical downlink sharing channel (PDSCH), a physical uplink control channel (PUCCH), and a physical uplink sharing channel (PUSCH). The signal includes at least one of the following: a channel status information reference signal (CSI RS) and a sounding reference signal (SRS).

[0045] Selectively, each of the above signals may be any type of signal from among periodic, semi-persistent, and aperiodic.

[0046] Furthermore, at least one of the at least two sets of TCI states indicated by the first instruction information includes a joint TCI state (or referred to as DL or jointTCIstate), meaning that the joint TCI state can use the uplink and downlink channels / reference signals simultaneously.

[0047] Alternatively, at least one of the two sets of TCI states includes an independent uplink (UL) TCI state and / or a downlink (DL) TCI state.

[0048] The settings for channels and / or signals are used to indicate whether the channels and signals are transmitted based on one set of TCI states or multiple sets of TCI states.

[0049] Optionally, the Disclosure determines the number of TCI states based on transmission based on the number of transmission and reception points (TRPs) for a channel and / or signal configuration. For example, if a CSI RS and an SRS each configure a single (S)TRP, it can be determined that the configuration is a transmission based on one set of TCI states, or if a PDCCH channel configures multiple (M)TRPs, it can be determined that the PDCCH configuration is a transmission based on multiple sets of TCI states, and so on.

[0050] Selectively, each of the above signals may be transmitted based on S-TRP, meaning each signal is configured as a transmission based on one set of TCI states.

[0051] Selectively, regarding the setting being a channel of multiple sets of TCI states, it can be directly determined that the TCI states for channel transmission are at least two sets of TCI states indicated by the first instruction information.

[0052] Regarding the setting being a channel and / or signal based on a set of TCI states, one set of TCI states for the transmission of the channel and / or signal can be determined from at least two sets of TCI states indicated by the first instruction information. For example, one set specified in the first instruction information can be determined as the TCI state for the transmission of the channel and / or signal.

[0053] In this disclosure, a terminal device can determine the TCI state for its transmission based on the settings for the channel and / or signal, after receiving at least two sets of TCI states instructed by a network device. This ensures that the TCI state for the channel and / or signal transmission determined by the terminal device is consistent with that determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0054] Referring to Figure 3, which is a flowchart of a method for determining another transmission setting instruction state provided by an embodiment of the present disclosure. The method is performed by a terminal device. As shown in Figure 3, the method may include, but is not limited to, the following steps: step 301, receiving first instruction information, the first instruction information is used to indicate at least two sets of transmission setting instruction (TCI) states.

[0055] The specific implementation process of step 301 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0056] Step 302, in response to the setting for the channel and / or signal being a transmission based on one set of TCI states, it is determined that one specified set of TCI states in at least two sets of TCI states is the TCI state for the transmission of the channel and / or signal.

[0057] Selectively, the specified TCI state may be any one of the first set of TCI states in the first instruction information and the set of TCI states associated with the specified group identifier.

[0058] The first set of TCI states may be a single set of TCI states located at the lowest bit field position in the first instruction information.

[0059] For example, the first set of TCI states may be a single set of TCI states located at the lowest bit field position in MAC CE.

[0060] Alternatively, the first set of TCI states may be the set of TCI states with the smallest TCI state identifier in the first instruction information.

[0061] Selectively, the first instruction information includes a group identifier (Identity document, ID) or index associated with each set of TCI states. This allows a terminal device, after receiving the first instruction information, to determine that one set of TCI states associated with a specified group identifier in the first instruction information is the TCI state for a channel and / or signal for transmission based on one set of TCI states.

[0062] The group identifier includes at least one of the following: the CORESET Pool Index, the CORESET group identifier, the physical uplink control channel (PUCCH) group identifier, the physical uplink shared channel (PUSCH) group identifier, and the physical downlink shared channel (PDSCH) group identifier.

[0063] In other words, the first instruction information may include the CORESET Pool Index or CORESET group ID or PUCCH group ID or PUSCH group ID or PDSCH group ID associated with the TCI state of each set.

[0064] In this disclosure, after receiving at least two sets of TCI states instructed by a network device, a terminal device can determine that the TCI state for transmission of a channel and / or signal is a specified set of at least two sets of TCI states, for the configuration being based on one set of TCI states. This ensures that the TCI state for transmission of the channel and / or signal determined by the terminal device is consistent with that determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0065] Referring to Figure 4, which is a flowchart of a method for determining another transmission setting instruction state provided by an embodiment of the present disclosure. The method is performed by a terminal device. As shown in Figure 4, the method may include, but is not limited to, the following steps: step 401, receiving first instruction information, the first instruction information is used to indicate at least two sets of transmission setting instruction (TCI) states.

[0066] Specific implementations of step 401 described above can be found in the detailed description of any embodiment in this disclosure and will not be described further here.

[0067] Step 402, in response to the fact that the configuration for any channel is a transmission based on multiple sets of TCI states, it is determined that at least two sets of TCI states are all TCI states for the transmission of the any channel.

[0068] Selectively, in PDCCH, PDSCH, PUCCH, and PUSCH, the configuration for at least one channel may be a transmission based on one set of TCI states, or the configuration for at least one channel may be a transmission based on multiple sets of TCI states.

[0069] For example, the following combinations of settings for each channel may be used: S-TRP PDCCH and M-TRP PDSCH; S-TRP PDSCH and M-TRP PDCCH; S-TRP PDCCH and M-TRP PUSCH; S-TRP PUSCH and M-TRP PDCCH; S-TRP PUSCH and M-TRP PDSCH; S-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PDSCH and M-TRP PUCCH; S-TRP PDCCH, S-TRP PUCCH, M-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PUCCH, M-TRP PDSCH and M-TRP PUSCH, etc.

[0070] An M-TRP PDCCH may include setting up a set of search space (SS) with two link relationships, where PDCCH candidates with the same candidate number in the two SS sets are used to transmit one PDCCH, and each SS set is associated with its respective CORESET. Alternatively, an M-TRP PDCCH may include setting up a single frequency network (SFN), where one CORESET sets up two TCI states, and any single PDCCH candidate in that CORESET is associated with both TCI states.

[0071] An M-TRP PDSCH refers to a PDSCH in which a repetitionscheme, a repetitionsnumber, or two code division multiplexing (CDM) groups are set. The repetitionscheme includes at least one of the following: frequency division multiplexing (FDM) scheme A, FDM scheme B, or time division multiplexing (TDM) scheme A.

[0072] An M-TRP PUSCH refers to a PUSCH being associated with at least one of the following: two sounding reference signal resource indicators (SRS), two layer fields, two PUSCH precoder fields, and two SRS resource sets.

[0073] M-TRP PUCCH refers to the PUCCH being associated with at least one of the following: two spatial-relation-info, two TCI states (including independent UL TCI states or joint TCI states), and two power control parameter sets.

[0074] For different combinations of channel settings, terminal devices can use different methods to determine the TCI state of the channel for transmission based on a set of TCI states.

[0075] For example, in the four channels described above, if the settings for each channel are TCI states based on multiple sets, the terminal device can determine that at least two sets of TCI states indicated by the first instruction channel are all TCI states for each channel transmission.

[0076] In this disclosure, after a terminal device receives at least two sets of TCI states instructed by a network device, it can determine that the configuration is a channel for multi-set TCI state transmission, and that the TCI states for that transmission are the at least two sets of TCI states instructed. This ensures that the TCI states for channel and / or signal transmission determined by the terminal device are consistent with those determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0077] Referring to Figure 5, which is a flowchart of a method for determining another transmission setting instruction state provided by an embodiment of the present disclosure. The method is performed by a terminal device. As shown in Figure 5, the method may include, but is not limited to, the following steps: step 501, receiving first instruction information, the first instruction information is used to indicate at least two sets of transmission setting instruction (TCI) states.

[0078] Specific implementations of step 501 described above can be found in the detailed description of any embodiment in this disclosure and will not be described further here.

[0079] Step 502, in response to the fact that the configuration for any channel is a transmission based on one set of TCI states, it is determined that of at least two sets of TCI states, one set of TCI states in which the associated group identifier and the group identifier associated with the arbitrary channel are the same is the TCI state for the arbitrary channel transmission.

[0080] For example, if the PDCCH setting is S-TRP and the first instruction information includes a group identifier associated with each set of TCI states, then it can be determined that one set of TCI states whose associated group identifier and the group identifier associated with the PDCCH are the same is the TCI state for PDCCH transmission.

[0081] If the settings for a channel are selectable such that at least one first channel is a transmission based on one set of TCI states and at least one second channel is a transmission based on multiple sets of TCI states, then it can be determined that at least two sets of TCI states are all TCI states for at least one second channel transmission, and based on additional information, one set of TCI states for at least one first channel transmission can be determined.

[0082] For example, the settings for a channel may be any combination of the following: the PDCCH setting is based on transmission of multiple sets of TCI states, and at least one of the remaining channel settings is based on transmission of one set of TCI states; or the PDSCH setting is based on transmission of multiple sets of TCI states, and the PUSCH and / or PUCCH setting is based on transmission of one set of TCI states; or the PUSCH and / or PUCCH setting is based on transmission of multiple sets of TCI states, and the PDSCH setting is based on transmission of one set of TCI states; or the PUSCH setting is based on transmission of one set of TCI states, and the PUCCH setting is based on transmission of multiple sets of TCI states, and so on.

[0083] It should be noted that the above-mentioned combination format is merely an illustrative example and does not constitute a limited explanation for determining the TCI state for channel transmission in this disclosure.

[0084] Optionally, the additional information may be any one of the following: a group identifier associated with at least one channel; a code point value in the instruction field for indicating the SRS resource set index in the downlink control information (DCI); information indicated by the information field for indicating the downlink assignment in the downlink control information; and information indicated by a newly added information field in the downlink control information.

[0085] The additional instruction information, which can be selected, may further be MAC CE or RRC. The additional instruction information may further be other information fields in the first instruction information.

[0086] For example, if the PUSCH setting is S-TRP, the added instruction information can multiplex code point values ​​in the instruction field for indicating SRS resource set in DCI format 0_1 ​​and DCI format 0_2. Which TCI state the code point value indicates determines which TCI state the PUSCH transmission will use. For example, if the code point value indicates that the SRS resource indicator field and precoding information and number of layers field are associated with a first SRS resource set, it indicates that the TCI state of the first set will be used; if the code point value indicates that the SRS resource indicator field and precoding information and number of layers field are associated with a second SRS resource set, it indicates that the TCI state of the second set will be used, and vice versa.

[0087] Alternatively, if the PDSCH setting is S-TRP, and the instruction information in 1 is DCI format 1_1 and 1_2, and there is no downlink setting (without DL assignment), the information field for indicating DL assignment in DCI can be multiplexed to indicate which TCI state the PDSCH should use.

[0088] Alternatively, if the first instruction information is DCI format 1_1 and 1_2 with DL assignment, a new instruction field can be added to indicate which TCI state a channel based on a set of TCI states should use.

[0089] In this disclosure, after a terminal device receives at least two sets of TCI states indicated by a network device, it can determine that the configuration is a channel based on multiple sets of TCI states, and that the TCI states for transmission are at least two of the indicated sets of TCI states. This ensures that the TCI states for channel and / or signal transmission determined by the terminal device are consistent with those determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0090] Referring to Figure 6, which is a flowchart of a method for determining another transmission setting instruction state provided by an embodiment of the present disclosure. The method is performed by a terminal device. As shown in Figure 6, the method may include, but is not limited to, the following steps: step 601, receiving first instruction information, the first instruction information is used to indicate at least two sets of transmission setting instruction (TCI) states.

[0091] Specific implementations of step 601 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0092] Step 602: The second instruction information is received and used to indicate the TCI state of the second set of instruction information.

[0093] The first and / or second instruction information may be MAC CE and any one of DCI and MAC CE, respectively. The different ways in which different types of instruction information indicate the TCI state can be found in the description of any embodiment of this disclosure and will not be described further here.

[0094] Step 603, in response to the fact that the configuration for at least one third channel is a transmission based on multiple sets of TCI states and the configuration for the remaining at least one fourth channel is a transmission based on one set of TCI states, the step of determining that at least two sets of TCI states are both TCI states for third channel transmission and determining one set of TCI states for the remaining at least one fourth channel transmission based on the second instruction information.

[0095] In this disclosure, if a terminal device receives a second instruction information indicating one set of TCI states and a first instruction information indicating at least two sets of TCI states, the terminal device can determine one set of TCI states in the second instruction information as the TCI states for a fourth channel transmission, and at least two sets of TCI states in the first instruction information as the TCI states for a third channel transmission.

[0096] At least one channel of a transmission based on multiple TCI states may be at least one of PDCCH, PUCCH, PDSCH, or PUSCH, and accordingly, at least one of the remaining channels other than the at least one channel whose configuration is a transmission based on multiple TCI states may be configured as a transmission based on one TCI state. Each of the four channels described above may be configured as a transmission based on several TCI states and may be combined as desired, and this disclosure is not limited thereto.

[0097] For example, if the PDCCH configuration is M-TRP, the PDCCH may include configuring a set of search space (SS) with two link relationships, where PDCCH candidates with the same candidate number in the two SS sets are used to transmit one PDCCH, and each SS set is associated with its respective CORESET. Alternatively, the M-TRP PDCCH may include configuring a single frequency network (SFN), where one CORESET configures two TCI states, and any single PDCCH candidate in that CORESET is associated with both TCI states.

[0098] In one embodiment, if PDCCH is the channel that has set up M-TRP, and the transmission of S-TRP is that the other channels PUCCH, PUSCH, and PDSCH have all been set up, the first instruction information may be instruction information for indicating a unified TCI state or an indicated TCI state, that is, the instruction information is for indicating at least one set of TCI states for at least one channel. For example, the first instruction information is used to indicate the TCI state of PDCCH, but this TCI state can be applied to at least one CORESET. The second instruction information may also be instruction information for indicating a unified TCI state or an indicated TCI state, that is, the instruction information is used to indicate the TCI state of at least one channel. For example, the second instruction information is used to indicate a TCI state that applies to all of PDSCH, PUCCH, and PUSCH. Each set of TCI states indicated by the first and second instruction information all include a joint TCI state or include at least one of an independent DL TCI state and an independent UL TCI state. The first and second instruction information may each be MAC CE, or include MAC CE and DCI.

[0099] In another embodiment, if PDCCH is the channel that has set up the M-TRP, and the transmission of the S-TRP is that the other channels PUCCH, PUSCH, and PDSCH have all been set up, then the first instruction information may be instruction information for indicating the TCI state of one or two CORESETs associated with PDCCH, and such instruction information must indicate the CORESET ID associated with the CORESETs. The second instruction information may be instruction information for indicating a unified TCI state or an indicated TCI state, that is, such instruction information is used to indicate the TCI state of at least one channel. For example, the second instruction information is used to indicate the TCI state that applies to all of PDSCH, PUCCH, and PUSCH. The TCI states of each set indicated by the first and second instruction information all include a joint TCI state or include at least one of an independent DL TCI state and an independent UL TCI state. The first instruction information is MAC CE. The second instruction information may include MAC CE, or MAC CE and DCI.

[0100] In this disclosure, after receiving first instruction information indicating at least two sets of TCI states and second instruction information indicating one set of TCI states transmitted by a network device, the terminal device can determine that, if the configuration type is a channel based on multiple sets of TCI states, the TCI states for transmission are at least two sets of TCI states indicated by the first instruction information, and if the configuration type is a channel based on one set of TCI states, the TCI states for transmission are one set of TCI states indicated by the second instruction information. This ensures consistency between the TCI states for channel and / or signal transmission determined by the terminal device and those determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0101] Referring to Figure 7, which is a flowchart of a method for determining another transmission configuration instruction state provided by an embodiment of the present disclosure. The method is performed by a network device. As shown in Figure 7, the method may include, but is not limited to, the following steps: step 701, sending first instruction information to a terminal device, the first instruction information being used to indicate at least two sets of transmission configuration instruction (TCI) states.

[0102] A set of TCI states refers to one TCI state or a pair of TCI states. For example, a set of TCI states may be one joint TCI state (or DL ​​or jointTCIstate), one independent downlink (DL) TCI state, one independent uplink (UL) TCI state, or one independent DL TCI state and one independent UL TCI state, and this disclosure is not limited thereto.

[0103] Selectively, the first instruction information may be a medium access control layer (MAC) control element (CE), i.e., at least two sets of TCI states associated with a single codepoint are activated via the MAC CE.

[0104] Selectively, the first instruction information may further include MAC CE and DCI. That is, first, MAC CE directly activates at least one set of TCI states, each associated with multiple codepoints, and DCI indicates one of those codepoints, which is associated with at least two sets of TCI states.

[0105] Step 702: Based on the settings for the channel and / or signal in the terminal device, determine the TCI state for channel and / or signal transmission.

[0106] The channel includes at least one of the following: a physical downlink control channel (PDCCH), a physical downlink sharing channel (PDSCH), a physical uplink control channel (PUCCH), and a physical uplink sharing channel (PUSCH). The signal includes at least one of the following: a channel status information reference signal (CSI RS) and a sounding reference signal (SRS).

[0107] Selectively, each of the above signals may be any type of signal from among periodic, semi-persistent, and aperiodic.

[0108] Furthermore, at least one of the at least two sets of TCI states indicated by the first instruction information includes a joint TCI state (or referred to as DL or jointTCIstate), meaning that the joint TCI state can use the uplink and downlink channels / reference signals simultaneously.

[0109] Alternatively, at least one of the two sets of TCI states includes an independent uplink (UL) TCI state and / or a downlink (DL) TCI state.

[0110] The settings for channels and / or signals in a terminal device are used to indicate whether the channels and / or signals are transmitted based on one set of TCI states or multiple sets of TCI states.

[0111] Selectively, the Disclosure determines the configuration based on the number of transmission and / or signal configuration nodes (TRPs). For example, if a CSI RS and an SRS single (S)TRP are configured, it can be determined that the configuration is a transmission based on one set of TCI states; or, if a PDCCH channel has multiple (M)TRPs, it can be determined that the PDCCH configuration is a transmission based on multiple sets of TCI states, etc.

[0112] Selectively, each of the above signals may be transmitted based on S-TRP, meaning each signal is configured as a transmission based on one set of TCI states.

[0113] Selectively, regarding the setting being a channel of multiple sets of TCI states, it can be directly determined that the TCI states for channel transmission are at least two sets of TCI states indicated by the first instruction information.

[0114] For a transmission where the setting is one set of TCI states, then one set of TCI states for that transmission can be determined from at least two sets of TCI states indicated by the first instruction information. For example, one set specified in the first instruction information can be determined as the TCI state for the transmission of the channel and / or signal.

[0115] In this disclosure, a network device can instruct a terminal device to provide at least two sets of TCI states, and then determine the TCI state for transmission based on the settings for the channel and / or signal in the terminal device. This ensures that the TCI state for channel and / or signal transmission determined by the terminal device is consistent with that determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0116] Referring to Figure 8, which is a flowchart of a method for determining another transmission configuration instruction state provided by an embodiment of the present disclosure. The method is performed by a network device. As shown in Figure 8, the method may include, but is not limited to, the following steps: step 801, sending first instruction information to a terminal device, the first instruction information being used to indicate at least two sets of transmission configuration instruction (TCI) states.

[0117] The specific implementation process of step 801 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0118] Step 802, in response to the setting for a channel and / or signal in the terminal device being a transmission based on a set of TCI states, it is determined that one specified set of TCI states in the at least two sets of TCI states is the TCI state for the transmission of the channel and / or signal.

[0119] Selectively, the specified TCI state may be any one of the first set of TCI states in the first instruction information and the set of TCI states associated with the specified group identifier.

[0120] The first set of TCI states may be a single set of TCI states located at the lowest bit field position in the first instruction information.

[0121] For example, the first set of TCI states may be a single set of TCI states located at the lowest bit field position in MAC CE.

[0122] Alternatively, the first set of TCI states may be the set of TCI states with the smallest TCI state identifier in the first instruction information.

[0123] Selectively, the first instruction information includes a group identifier (Identity document, ID) or index associated with each set of TCI states. This allows a terminal device, after receiving the first instruction information, to determine that one set of TCI states associated with a specified group identifier in the first instruction information is the TCI state for a channel and / or signal for transmission based on one set of TCI states.

[0124] The group identifier includes at least one of the following: the CORESET Pool Index, the CORESET group identifier, the physical uplink control channel (PUCCH) group identifier, the physical uplink shared channel (PUSCH) group identifier, and the physical downlink shared channel (PDSCH) group identifier.

[0125] In other words, the first instruction information may include the CORESET Pool Index or CORESET group ID or PUCCH group ID or PUSCH group ID or PDSCH group ID associated with the TCI state of each set.

[0126] In this disclosure, after the network device has instructed the terminal device to provide at least two sets of TCI states, it can determine that for channels and / or signals whose type is based on one set of TCI states, the TCI state for transmission is a specified set of at least two sets of TCI states. This ensures that the TCI state for transmission of channels and / or signals determined by the terminal device is consistent with that determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0127] Referring to Figure 9, which is a flowchart of a method for determining another transmission configuration instruction state provided by an embodiment of the present disclosure. The method is performed by a network device. As shown in Figure 9, the method may include, but is not limited to, the following steps: step 901, sending first instruction information to a terminal device, the first instruction information being used to indicate at least two sets of transmission configuration instruction (TCI) states.

[0128] Specific implementations of step 901 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0129] Step 902, in response to the fact that the configuration for any channel is a transmission based on multiple sets of TCI states, it is determined that at least two sets of TCI states are all TCI states for the transmission of the arbitrary channel.

[0130] Selectively, in PDCCH, PDSCH, PUCCH, and PUSCH, the configuration for at least one channel may be a transmission based on one set of TCI states, or the configuration for at least one channel may be a transmission based on multiple sets of TCI states.

[0131] For example, the following combinations of settings for each channel may be used: S-TRP PDCCH and M-TRP PDSCH; S-TRP PDSCH and M-TRP PDCCH; S-TRP PDCCH and M-TRP PUSCH; S-TRP PUSCH and M-TRP PDCCH; S-TRP PUSCH and M-TRP PDSCH; S-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PDSCH and M-TRP PUCCH; S-TRP PDCCH, S-TRP PUCCH, M-TRP PDSCH and M-TRP PUSCH; S-TRP PDCCH, M-TRP PUCCH, M-TRP PDSCH and M-TRP PUSCH, etc.

[0132] In this configuration, the M-TRP PDCCH may include setting up a set of search space (SS) with two link relationships, where PDCCH candidates with the same candidate number in the two SS sets are used to transmit one PDCCH, and each SS set is associated with its respective CORESET. Alternatively, the M-TRP PDCCH may include setting up a single frequency network (SFN), where one CORESET sets up two TCI states, and any single PDCCH candidate in that CORESET is associated with the transmission of both TCI states.

[0133] In this context, M-TRP PDSCH refers to the setting of a repetitionscheme, a repetitionsnumber, or two code division multiplexing (CDM) groups in the PDSCH. The repetitionscheme includes at least one of the following: frequency division multiplexing (FDM) scheme A, FDM scheme B, or time division multiplexing (TDM) scheme A.

[0134] An M-TRP PUSCH refers to a PUSCH being associated with at least one of the following: two sounding reference signal resource indicators (SRS), two layer fields, two PUSCH precoder fields, and two SRS resource sets.

[0135] M-TRP PUCCH refers to the PUCCH being associated with at least one of the following: two spatial-relation-info, two TCI states (including independent UL TCI states or joint TCI states), and two power control parameter sets.

[0136] For different combinations of channel settings, terminal devices use different methods to determine the TCI state for channel transmission based on a set of TCI states.

[0137] For example, if the settings for each of the four channels described above are based on multiple sets of TCI states, the terminal device can determine that at least two sets of TCI states indicated by the first instruction channel are all TCI states for each channel transmission.

[0138] In this disclosure, after a network device has instructed a terminal device with at least two sets of TCI states, it can determine that the type set on the terminal device is a channel based on multiple sets of TCI states, and that the TCI states for transmission are the at least two sets of instructed TCI states. This ensures that the TCI states for channel and / or signal transmission determined by the terminal device are consistent with those determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0139] Referring to Figure 10, which is a flowchart of a method for determining another transmission configuration instruction state provided by an embodiment of the present disclosure. The method is performed by a network device. As shown in Figure 10, the method may include, but is not limited to, the following steps: step 1001, sending first instruction information to a terminal device, the first instruction information being used to indicate at least two sets of transmission configuration instruction (TCI) states.

[0140] Specific implementations of step 1001 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0141] Step 1002: In response to the fact that the configuration for any channel is a transmission based on one set of TCI states, it is determined that one set of TCI states, out of at least two sets of TCI states, is the TCI state for the arbitrary channel transmission, where the associated group identifier and the group identifier associated with the arbitrary channel are the same.

[0142] For example, if the PDCCH setting is S-TRP and the first instruction information includes a group identifier associated with each set of TCI states, then it can be determined that the set of TCI states whose associated group identifier and the group identifier associated with the PDCCH are the same is the TCI state for PDCCH transmission.

[0143] If the settings for a channel are selectable such that at least one first channel is a transmission based on one set of TCI states and at least one second channel is a transmission based on multiple sets of TCI states, then it can be determined that at least two sets of TCI states are all TCI states for at least one second channel transmission, and based on additional information, one set of TCI states for at least one first channel transmission can be determined.

[0144] For example, the channel settings may be any combination of the following: the PDCCH setting is based on transmission of multiple sets of TCI states, and at least one of the remaining channel settings is based on transmission of one set of TCI states; the PDSCH setting is based on transmission of multiple sets of TCI states, and the PUSCH and / or PUCCH setting is based on transmission of one set of TCI states; the PUSCH and / or PUCCH setting is based on transmission of multiple sets of TCI states, and the PDSCH setting is based on transmission of one set of TCI states; the PUSCH setting is based on transmission of multiple sets of TCI states, and the PUCCH setting is based on transmission of one set of TCI states; or the PUSCH setting is based on transmission of one set of TCI states, and the PUCCH setting is based on transmission of multiple sets of TCI states.

[0145] It should be noted that the above-mentioned combination format is merely an illustrative example and does not constitute a limited explanation for determining the TCI state for channel transmission in this disclosure.

[0146] Optionally, the additional information may be any one of the following: a group identifier associated with at least one channel; a code point value in the instruction field for indicating the SRS resource set index in the downlink control information (DCI); information indicated by the information field for indicating the downlink assignment in the downlink control information; and information indicated by a newly added information field in the downlink control information.

[0147] The additional instruction information, which can be selected, may further be MAC CE or RRC. The additional instruction information may further be other information fields in the first instruction information.

[0148] For example, if the PUSCH setting is S-TRP, the added instruction information can multiplex code point values ​​in the instruction field for indicating SRS resource set in DCI format 0_1 ​​and DCI format 0_2. Which TCI state the code point value indicates determines which TCI state the PUSCH transmission will use. For example, if the code point value indicates that the SRS resource indicator field and precoding information and number of layers field are associated with a first SRS resource set, it indicates that the TCI state of the first set will be used; if the code point value indicates that the SRS resource indicator field and precoding information and number of layers field are associated with a second SRS resource set, it indicates that the TCI state of the second set will be used, and vice versa.

[0149] Alternatively, if the PDSCH setting is S-TRP, and the instruction information in 1 is DCI format 1_1 and 1_2, and there is no downlink setting (without DL assignment), the information field for indicating DL assignment in DCI can be multiplexed to indicate which TCI state the PDSCH should use.

[0150] Alternatively, if the first instruction information is DCI format 1_1 and 1_2 with DL assignment, a new instruction field can be added to indicate which TCI state a channel based on a set of TCI states should use.

[0151] In this disclosure, after a terminal device receives at least two sets of TCI states indicated by a network device, it can determine that the type of configuration is a channel based on multiple sets of TCI states, and that the TCI states for its transmission are at least two of the indicated sets of TCI states. This ensures that the TCI states for channel and / or signal transmission determined by the terminal device are consistent with those determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0152] Referring to Figure 11, which is a flowchart of a method for determining another transmission configuration instruction state provided by an embodiment of the present disclosure. The method is performed by a network device. As shown in Figure 11, the method may include, but is not limited to, the following steps: step 1101, sending first instruction information to a terminal device, the first instruction information being used to indicate at least two sets of transmission configuration instruction (TCI) states.

[0153] Specific implementations of step 601 described above can be found in the detailed description of any embodiment of this disclosure and will not be described further here.

[0154] Step 1102: A second instruction is sent to the terminal device, and the second instruction is used to instruct a set of TCI states.

[0155] The first and / or second instruction information may be MAC CE and any one of DCI and MAC CE, respectively. The different ways in which different types of instruction information indicate the TCI state can be found in the description of any embodiment of this disclosure and will not be described further here.

[0156] Step 1103, in response to the fact that the setting for at least one third channel is a transmission based on multiple sets of TCI states and the setting for the remaining at least one fourth channel is a transmission based on one set of TCI states, it is determined that at least two sets of TCI states are both TCI states for third channel transmission, and based on the second instruction information, one set of TCI states for the remaining at least one fourth channel transmission is determined.

[0157] In this disclosure, when a network device transmits a second instruction information to a terminal device that instructs one set of TCI states, and also transmits a first instruction information that instructs at least two sets of TCI states, one set of TCI states in the second instruction information can be determined as the TCI states for a fourth channel transmission, and at least two sets of TCI states in the first instruction information can be determined as the TCI states for a third channel transmission.

[0158] The configuration is at least one channel of transmission based on multiple sets of TCI states, which may be at least one of PDCCH, PUCCH, PDSCH, and PUSCH, and accordingly, at least one of the remaining channels other than the at least one channel in which the configuration is a transmission based on multiple sets of TCI states may be configured as a transmission based on one set of TCI states. Each of the four channels described above may be configured as a transmission based on several TCI states and may be combined as desired, and this disclosure is not limited thereto.

[0159] For example, if the PDCCH configuration is M-TRP, the PDCCH may include configuring a set of search space (SS) with two link relationships, where PDCCH candidates with the same candidate number in the two SS sets are used to transmit one PDCCH, and each SS set is associated with its respective CORESET. Alternatively, the M-TRP PDCCH may include configuring a single-frequency network (SFN) method, where one CORESET configures two TCI states, and any single PDCCH candidate in that CORESET is associated with both TCI states.

[0160] In one embodiment, if PDCCH is the channel that has set up M-TRP, and the transmission of S-TRP is that the other channels PUCCH, PUSCH, and PDSCH have all been set up, the first instruction information may be instruction information for indicating a unified TCI state or an indicated TCI state, that is, the instruction information is for indicating at least one set of TCI states for at least one channel. For example, the first instruction information is used to indicate the TCI state of PDCCH, but this TCI state can be applied to at least one CORESET. The second instruction information may also be instruction information for indicating a unified TCI state or an indicated TCI state, that is, the instruction information is used to indicate the TCI state of at least one channel. For example, the second instruction information is used to indicate a TCI state that applies to all of PDSCH, PUCCH, and PUSCH. Each set of TCI states indicated by the first and second instruction information all include a joint TCI state or include at least one of an independent DL TCI state and an independent UL TCI state. The first and second instruction information may each be MAC CE, or include MAC CE and DCI.

[0161] In another embodiment, if PDCCH is the channel that has set up the M-TRP, and the other channels PUCCH, PUSCH, and PDSCH have all been set up, then the transmission of the S-TRP may be the first instruction information, which may be the instruction information for indicating the TCI state of one or two CORESETs associated with PDCCH, and which must indicate the CORESET ID associated with the CORESETs. The second instruction information may be the instruction information for indicating a unified TCI state or an indicated TCI state, that is, which is used to indicate the TCI state of at least one channel. For example, the second instruction information may be used to indicate the TCI state that applies to all of PDSCH, PUCCH, and PUSCH. The TCI states of each set indicated by the first and second instruction information all include a joint TCI state, or include at least one of an independent DL TCI state and an independent UL TCI state, and the first instruction information is MAC CE. The second instruction information may include MAC CE, or MAC CE and DCI.

[0162] In this disclosure, after a network device transmits to a terminal device first instruction information indicating at least two sets of TCI states and second instruction information indicating one set of TCI states, the network device can determine that if the configuration is a channel based on multiple sets of TCI states, the TCI state for transmission is at least two sets of TCI states indicated by the first instruction information, and if the configuration is a channel based on one set of TCI states, the network device can determine that the TCI state for transmission is one set of TCI states indicated by the second instruction information. This ensures that the TCI state for channel and / or signal transmission determined by the terminal device matches that determined by the network device, guaranteeing transmission reliability and improving transmission quality.

[0163] Referring to Figure 12, a schematic configuration diagram of the communication device 1200 provided by an embodiment of the present disclosure is shown. The communication device 1200 shown in Figure 12 may include a transceiver module 1201. The transceiver module 1201 may include a transmit module and / or a receive module, the transmit module being used to implement a transmit function and the receive module being used to implement a receive function, and the transceiver module 1201 can implement both a transmit function and / or a receive function.

[0164] What can be understood is that the communication device 1200 may be a terminal device, a device within a terminal device, or a device that can be matched and used with a terminal device.

[0165] The communication device 1200 is located on the terminal device side, and within it: the transmit / receive module 1201 is used to receive first instruction information, which is used to indicate at least two sets of transmission setting instruction (TCI) states, and the processing module 1202 is used to determine the TCI state for channel and / or signal transmission based on the settings for the channel and / or signal.

[0166] Selectively, at least one of the at least two sets of TCI states includes one joint TCI state, or at least one of the at least two sets of TCI states includes an independent uplink (UL) TCI state and / or a downlink (DL) TCI state.

[0167] Selectively, the processing module 1202 is used to determine, specifically, in response to a setting for a channel and / or signal being a transmission based on one set of TCI states, that a specified set of TCI states in at least two sets of TCI states is a TCI state for channel and / or signal transmission, or in response to a setting for any channel being a transmission based on multiple sets of TCI states, that at least two sets of TCI states are all TCI states for any channel transmission.

[0168] Selectable, the specified TCI state is any one of the first set of TCI states in the first instruction information and one of the set of TCI states associated with the specified group identifier.

[0169] Selectively, the first set of TCI states is either a set of TCI states located at the lowest bit field position in the first instruction information, or a set of TCI states with the smallest TCI state identifier in the first instruction information.

[0170] Optionally, the first instruction information includes a group identifier associated with the TCI state for each set.

[0171] Selectively, the group identifier includes at least one of the following: control resource set pool index, control resource set group identifier, physical uplink control channel (PUCCH) group identifier, physical uplink shared channel (PUSCH) group identifier, and physical downlink shared channel (PDSCH) group identifier.

[0172] Selectively, the channel includes at least one of the following: physical downlink control channel (PDCCH), physical downlink sharing channel (PDSCH), physical uplink control channel (PUCCH), and physical uplink sharing channel (PUSCH), and the signal includes at least one of the following: channel status information reference signal (CSI RS) and sounding reference signal (SRS).

[0173] Selectively, at least one channel configuration is based on a single set of TCI states for transmission, and at least one channel configuration is based on multiple sets of TCI states for transmission.

[0174] Selectively, in response to the fact that the configuration for any channel is a transmission based on one set of TCI states, the processing module 1202 uses at least two sets of TCI states to determine that one set of TCI states, in which the associated group identifier and the group identifier associated with the arbitrary channel are the same, is the TCI state for the arbitrary channel transmission.

[0175] Selectively, the processing module 1202 is used to determine, specifically, in response to the settings for a channel being that at least one first channel is a transmission based on one set of TCI states and at least one second channel is a transmission based on multiple sets of TCI states, that at least two sets of TCI states are both TCI states for the at least one second channel transmission, and to determine one set of TCI states for the at least one first channel transmission based on additional information.

[0176] Selectively, the additional information may be any one of the following: a group identifier associated with at least one channel; a code point value in the instruction field for indicating the SRS resource set index in the downlink control information (DCI); information indicated by the information field for indicating the downlink assignment in the downlink control information; and information indicated by the newly added information field in the downlink control information.

[0177] Selectively, the processing module 1202 is used to determine, specifically in response to the fact that the setting for at least one third channel is a transmission based on multiple sets of TCI states and the setting for the remaining at least one fourth channel is a transmission based on one set of TCI states, that at least two sets of TCI states are TCI states for at least one third channel transmission and that one set of TCI states for the remaining at least one fourth channel transmission is determined based on the second instruction information.

[0178] Selectively, the first instruction information and / or the second instruction information are media intervention control layer control elements (MAC CE) and any one of the downlink control information (DCI) and MAC CE.

[0179] In this disclosure, a terminal device can determine the TCI state for its transmission based on the settings for the channel and / or signal, after receiving at least two sets of TCI states instructed by a network device. This ensures that the TCI state for the channel and / or signal transmission determined by the terminal device is consistent with that determined by the network device, guaranteeing transmission reliability and improving transmission quality.
