[0094] For the specific contents and implementation forms of step 31 and step 32, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanations will be omitted here.

[0095] In step 33, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0096] Here, the specified time interval may be stipulated by a protocol, may be set by a network device, or may be determined by a terminal device, and is not limited by this disclosure.

[0097] For example, if the specified time interval is K and the transmission time of the indication information is t, the terminal device can determine that the use time of the beam corresponding to the specified resource is t+K.

[0098] By implementing the embodiment of the present disclosure, the terminal device knows the beam corresponding to the specified resource in the second carrier by receiving DCI according to the PDCCH of the first carrier, then transmits indication information to indicate the receiving state of the DCI to the network device, and determines the use time of the beam corresponding to the specified resource according to the transmission time of the indication information and the specified time interval. This allows the terminal device and the network device to have a consistent understanding of the cross-carrier beam use time, ensures the consistency of the beam, reduces the impact on communication transmission, and improves the performance of beam transmission.

[0099] Referring to Fig. 4, Fig. 4 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 4, the method can include, but is not limited to, the following steps:

[0100] In step 41, receiving DCI based on the PDCCH of a first carrier for indicating a beam corresponding to a specified resource in a second carrier.

[0101] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0102] In step 42, indication information is transmitted to indicate the reception status of the DCI.

[0103] Note that, for the specific contents and implementation forms of step 41 and step 42, the explanations of other embodiments of the present disclosure can be referred to, and therefore the explanations are omitted here.

[0104] In step 43, in response to the DCI further indicating first resource information of a PDSCH and / or a PUSCH on a second carrier and second resource information of a PUCCH for transmitting the indication information, the specified time interval is determined based on at least one of the first resource information, the second resource information, and the third resource information of a PDCCH of the first carrier.

[0105] Optionally, the specified time interval can be determined based on a subcarrier spacing in the first resource information of the PDSCH on the second carrier, where the subcarrier spacing (SCS) may be 15 kilohertz (kHz), 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc., and is not limited in this disclosure.

[0106] For example, if the SCS in the first resource information is 15 kHz, the corresponding designated time interval is T1, if the SCS in the first resource information is 30 kHz, the corresponding designated time interval is T2, if the SCS in the first resource information is 60 kHz, the corresponding designated time interval is T3, etc., as stipulated by a protocol or set by a network device. In this way, the corresponding designated time interval can be determined based on the SCS in the first resource information of the terminal device. In this way, the terminal device and the network device can have a consistent understanding of the designated time interval, and a guarantee is provided for beam-based transmission.

[0107] Alternatively, the designated time interval may be determined based on the first resource information of the PUSCH in the second carrier, or the designated time interval may be determined based on the first resource information of the PDSCH and the PUSCH in the second carrier. For specific contents and implementation forms, please refer to the descriptions of each embodiment of the present disclosure, and the description will be omitted here.

[0108] Optionally, the specified time interval may be determined based on the SCS in the second resource information.

[0109] For example, if the SCS in the second resource information is 15 kHz, the corresponding designated time interval is T4, if the SCS in the second resource information is 30 kHz, the corresponding designated time interval is T5, if the SCS in the second resource information is 60 kHz, the corresponding designated time interval is T6, etc., as stipulated by a protocol or set by a network device. This allows the terminal device to determine the corresponding designated time interval based on the SCS in the second resource information. This allows the terminal device and the network device to have a consistent understanding of the designated time interval, providing a guarantee for beam-based transmission.

[0110] Optionally, the designated time interval may be determined based on a subcarrier spacing (SCS) in the first resource information and an SCS in the second resource information.

[0111] For example, if the SCS in the first resource information and the second resource information are the same, the corresponding designated time interval is T7, if the SCS in the first resource information is larger than the SCS in the second resource information, the corresponding designated time interval is T8, if the SCS in the first resource information is smaller than the SCS in the second resource information, the corresponding designated time interval is T9, etc., are stipulated by a protocol or set by a network device. This allows the terminal device to determine the corresponding designated time interval based on the SCS in the first resource information and the second resource information. This allows the terminal device and the network device to maintain a consistent understanding of the designated time interval, providing a guarantee for beam-based transmission.

[0112] Note that the above example is merely an example and does not limit the method of determining the specified time interval in the embodiment of the present disclosure.

[0113] Alternatively, the specified time interval may be determined based on the third resource information, and the specific content and implementation form thereof may refer to the description of each embodiment of the present disclosure, and the description will be omitted here.

[0114] It should be noted that the designated time interval may be determined using one of the above, or may be determined using a plurality of the above, and is not limited in this disclosure.

[0115] In step 44, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0116] For the specific content and implementation form of step 44, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanation will be omitted here.

[0117] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the designated resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then transmit indication information to indicate the reception status of the DCI to the network device, and then first determine the designated time interval based on the first resource information, the second resource information, and the third resource information of the PDCCH of the first carrier, and then determine the use time of the beam corresponding to the designated resource based on the transmission time of the indication information and the designated time interval. This allows the terminal device and the network device to maintain a consistent understanding of the cross-carrier beam use time, ensures the integrity of the beam, reduces the impact on communication transmission, and improves the performance of beam transmission.

[0118] Referring to Fig. 5, Fig. 5 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 5, the method can include, but is not limited to, the following steps:

[0119] In step 51, receiving DCI based on the PDCCH of a first carrier to indicate a beam corresponding to a specified resource in a second carrier.

[0120] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0121] In step 52, indication information is transmitted to indicate the reception status of the DCI.

[0122] For the specific contents and implementation forms of step 51 and step 52, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanations will be omitted here.

[0123] In step 53, in response to the DCI further indicating first resource information of a PDSCH and / or a PUSCH on a second carrier and second resource information of a PUCCH for transmitting the indication information, the specified time interval is determined based on at least one of a subcarrier spacing (SCS) in the first resource information and an SCS in the second resource information.

[0124] Optionally, if the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the specified time interval may be determined based on the SCS in the first resource information.

[0125] Note that, if the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the SCS in the third resource information is not smaller than the SCS in the first resource information.

[0126] For example, if the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the specified time interval is regulated by a protocol or set by a network device to be related to the SCS in the first resource information. For example, if the specified time interval is N symbols and the SCS in the first resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and if the SCS in the first resource information is 30 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 30 KHz.

[0127] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the correspondence between the SCS in the first resource information and the specified time interval may be regulated by a protocol or set by a network device.

[0128] Thus, when the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the terminal device can determine the corresponding designated time interval based on the SCS in the first resource information, thereby allowing the terminal device and the network device to maintain a consistent understanding of the designated time interval, and providing a guarantee for beam-based transmission.

[0129] Optionally, if the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the specified time interval may be determined based on the SCS in the second resource information.

[0130] For example, if the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the specified time interval is related to the SCS in the second resource information, as stipulated by a protocol or set by a network device. For example, if the specified time interval is N symbols and the SCS in the second resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and if the SCS in the second resource information is 30 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 30 KHz.

[0131] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the correspondence between the SCS in the second resource information and the specified time interval may be regulated by a protocol or set by a network device.

[0132] Thus, when the SCS in the third resource information is equal to or greater than the SCS in the first resource information, the terminal device can determine the corresponding designated time interval based on the SCS in the second resource information, thereby allowing the terminal device and the network device to maintain a consistent understanding of the designated time interval, and providing a guarantee for beam-based transmission.

[0133] Optionally, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval is determined based on the SCS in the first resource information.

[0134] For example, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval is regulated by a protocol or set by a network device to be related to the SCS in the first resource information. For example, if the specified time interval is N symbols and the SCS in the first resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and if the SCS in the first resource information is 30 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 30 KHz.

[0135] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the correspondence between the SCS in the first resource information and the specified time interval may be regulated by a protocol or set by a network device.

[0136] Thus, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the terminal device can determine the corresponding designated time interval based on the SCS in the first resource information, thereby allowing the terminal device and the network device to maintain a consistent understanding of the designated time interval, and providing a guarantee for beam-based transmission.

[0137] Optionally, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, determine the specified time interval based on the SCS in the second resource information.

[0138] For example, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval is regulated by a protocol or set by a network device to be related to the SCS in the second resource information. For example, if the specified time interval is N symbols and the SCS in the second resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and if the SCS in the second resource information is 30 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 30 KHz.

[0139] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the correspondence between the SCS in the second resource information and the specified time interval may be regulated by a protocol or set by a network device.

[0140] Thus, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the terminal device can determine the corresponding designated time interval based on the SCS in the second resource information, thereby allowing the terminal device and the network device to maintain a consistent understanding of the designated time interval, and providing a guarantee for beam-based transmission.

[0141] It should be noted that the designated time interval may be determined by one of the above methods, or may be determined by a plurality of the above methods, and is not limited in this disclosure.

[0142] In step 54, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0143] For the specific content and implementation form of step 54, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanation will be omitted here.

[0144] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the designated resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then transmit indication information to indicate the reception state of the DCI to the network device, then determine the designated time interval based on the subcarrier spacing (SCS) in the first resource information and / or the SCS in the second resource information, and determine the use time of the beam corresponding to the designated resource based on the transmission time of the indication information and the designated time interval. This allows the terminal device and the network device to maintain a consistent understanding of the cross-carrier beam use time, ensures beam consistency, reduces the impact on communication transmission, and improves performance by beam transmission.

[0145] Referring to Fig. 6, Fig. 6 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 6, the method can include, but is not limited to, the following steps:

[0146] In step 61, receiving DCI based on the PDCCH of the first carrier for indicating a beam corresponding to a specified resource in the second carrier.

[0147] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0148] In step 62, indication information is transmitted to indicate the reception status of the DCI.

[0149] Note that, for the specific contents and implementation forms of step 61 and step 62, the explanations of other embodiments of the present disclosure can be referred to, and therefore the explanations are omitted here.

[0150] In step 63, in response to the DCI further indicating first resource information of a PDSCH and / or a PUSCH on a second carrier and second resource information of a PUCCH for transmitting the indication information, a first sub-time in the specified time interval is determined based on at least one of a subcarrier spacing (SCS) in the first resource information and an SCS in the second resource information.

[0151] Optionally, if the SCS in the third resource information is smaller than the SCS in the first resource information, the first sub-time in the specified time interval can be determined based on the SCS in the first resource information.

[0152] Here, the SCS may be 15 kHz, 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc., and is not limited in this disclosure.

[0153] For example, when the SCS in the third resource information is smaller than the SCS in the first resource information, the correspondence between the SCS in the first resource information and the first sub-time in the specified time interval is regulated by a protocol or set by a network device. For example, when the specified time interval is N symbols and the SCS in the first resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and when the SCS in the first resource information is 30 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 30 KHz, and the like, is not limited in the present disclosure.

[0154] Thus, the terminal device can determine the first sub-time in the corresponding specified time interval according to the SCS and the corresponding relationship in the first resource information, so that the terminal device and the network device can have a consistent understanding of the first sub-time in the specified time interval, and provide a guarantee for the beam-based transmission.

[0155] Alternatively, if the SCS in the third resource information is smaller than the SCS in the first resource information, the first sub-time in the specified time interval can be determined according to the SCS in the second resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0156] Optionally, if the SCS in the third resource information is smaller than the SCS in the second resource information, determine the first sub-time in the specified time interval according to the SCS in the first resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0157] Optionally, if the SCS in the third resource information is smaller than the SCS in the second resource information, determine the first sub-time in the specified time interval according to the SCS in the second resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0158] It should be noted that the designated time interval may be determined by one of the above methods, or may be determined by a plurality of the above methods, and is not limited in this disclosure.

[0159] In step 64, a second sub-time in the specified time interval is determined based on a subcarrier spacing (SCS) in the first resource information and / or an SCS in the second resource information.

[0160] Optionally, a second sub-time in the specified time interval may be determined based on an SCS in the first resource information and an SCS in the third resource information.

[0161] For example, if the SCS in the third resource information is smaller than the SCS in the first resource information, the second sub-time in the corresponding specified time interval is regulated by a protocol or set by a network device to be T.

[0162] Alternatively, the correspondence between the SCS in the third resource information, the SCS in the first resource information, and the second sub-time in the specified time interval may be regulated by a protocol or set by a network device.

[0163] Thus, the terminal device can determine the second sub-time in the corresponding specified time interval based on the SCS in the third resource information, the SCS in the first resource information, and the corresponding relationship, so that the terminal device and the network device can have a consistent understanding of the second sub-time in the specified time interval, and a guarantee is provided for the beam-based transmission.

[0164] Optionally, in the present disclosure, a second resource information and the SCS in the third resource information, a second sub-time in the specified time interval may be determined.

[0165] For example, the correspondence between the SCS in the third resource information, the SCS in the second resource information, and the second sub-time in the specified time interval may be regulated by a protocol or set by a network device. This allows the terminal device to determine the second sub-time in the corresponding specified time interval based on the SCS in the third resource information and the SCS in the second resource information. This allows the terminal device and the network device to maintain a consistent understanding of the second sub-time in the specified time interval, providing a guarantee for beam-based transmission.

[0166] Optionally, the SCS in the first resource information, the second resource informationand the SCS in the third resource information, a second sub-time in the specified time interval may be determined.

[0167] For example, the correspondence between the SCS in the third resource information, the SCS in the second resource information, the SCS in the first resource information, and the second sub-time in the specified time interval may be regulated by a protocol or set by a network device. This allows the terminal device to determine the second sub-time in the corresponding specified time interval based on the SCS in the third resource information, the SCS in the second resource information, and the SCS in the first resource information. This allows the terminal device and the network device to maintain a consistent understanding of the second sub-time in the specified time interval, providing a guarantee for beam-based transmission.

[0168] Optionally, in the present disclosure, the second sub-time may be directly proportional to the SCS in the first resource information and inversely proportional to the SCS in the third resource information.

[0169] For example, the larger the SCS in the first resource information, the larger the second sub-time, and the larger the SCS in the third resource information, the smaller the second sub-time. This disclosure is not limited to this.

[0170] Optionally, in the present disclosure, the second sub-time may be directly proportional to the SCS in the second resource information and inversely proportional to the SCS in the third resource information.

[0171] For example, the larger the SCS in the second resource information, the larger the second sub-time, and the larger the SCS in the third resource information, the smaller the second sub-time.

[0172] Optionally, in the present disclosure, the second sub-time may be directly proportional to the SCS in the first resource information and the SCS in the second resource information, and inversely proportional to the SCS in the third resource information.

[0173] Alternatively, the first sub-time may be an integer number of time units and the second sub-time may also be an integer number of time units.

[0174] Here, the time unit may be at least one of a slot, a mini-slot, and a symbol, and is not limited in the present disclosure.

[0175] In addition, the first sub-time may include an integer number of slots, or the first sub-time may include an integer number of microslots, or the first sub-time may include an integer number of symbols, or the first sub-time may include an integer number of slots and an integer number of microslots, or the first sub-time may include an integer number of slots and an integer number of symbols, or the first sub-time may include an integer number of microslots and an integer number of symbols, or the first sub-time may include an integer number of slots, an integer number of microslots and an integer number of symbols.

[0176] Also, the second sub-time may include an integer number of slots, or the second sub-time may include an integer number of microslots, or the second sub-time may include an integer number of symbols, or the second sub-time may include an integer number of slots and an integer number of microslots, or the second sub-time may include an integer number of slots and an integer number of symbols, the second sub-time may include an integer number of microslots and an integer number of symbols, or the second sub-time may include an integer number of slots, an integer number of microslots and an integer number of symbols.

[0177] It should be noted that the time units included in the first sub-time and the second sub-time may be any combination of the above, for example, the first sub-time includes an integer number of symbols and the second sub-time includes an integer number of symbols, or, for example, the first sub-time includes an integer number of microslots and the second sub-time includes an integer number of symbols, etc., and are not limited in this disclosure.

[0178] Thus, the specified time interval may include at least one of the following types, and is not limited by this disclosure: an integer number of slots, an integer number of microslots, and an integer number of symbols.

[0179] In step 65, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0180] In addition, in the present disclosure, the specified time interval may be the sum of the first sub-time and the second sub-time.

[0181] For example, if the transmission time of the instruction information is time t, the first sub-time is T1, and the second sub-time is T2, the usage time of the beam corresponding to the designated resource in the second carrier may be t+T1+T2. This disclosure is not limited thereto.

[0182] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the specified resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then transmit the indication information to indicate the reception state of the DCI to the network device, then determine the first sub-time and the second sub-time in the specified time interval based on the subcarrier spacing (SCS) in the first resource information, the SCS in the second resource information, and / or the SCS in the third resource information, and then determine the use time of the beam corresponding to the specified resource based on the transmission time of the indication information and the specified time interval. This allows the terminal device and the network device to have a consistent understanding of the cross-carrier beam use time, ensures the integrity of the beam, reduces the impact on communication transmission, and improves the performance by the beam transmission.

[0183] Referring to Fig. 7, Fig. 7 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 7, the method can include, but is not limited to, the following steps:

[0184] In step 71, receiving DCI based on the PDCCH of the first carrier for indicating a beam corresponding to a specified resource in the second carrier.

[0185] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0186] In step 72, indication information is transmitted to indicate the reception status of the DCI.

[0187] Note that, for the specific contents and implementation forms of steps 71 and 72, the explanations of other embodiments of the present disclosure can be referred to, and therefore the explanations are omitted here.

[0188] In step 73, in response to the DCI indicating second resource information of the PUCCH for further transmitting the indication information, the specified time interval is determined based on the second resource information and / or the third resource information of the PDCCH of the first carrier.

[0189] In addition, the designated time interval may be determined based on the second resource information, or the designated time interval may be determined based on the third resource information, or the designated time interval may be determined based on the second resource information and the third resource information. For specific contents and implementation forms, the description of each of the other embodiments of the present disclosure may be referred to, and the description will be omitted here.

[0190] In step 74, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0191] For the specific content and implementation form of step 74, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanation will be omitted here.

[0192] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the designated resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then send indication information to indicate the reception status of the DCI to the network device, and then first determine the designated time interval based on the second resource information and the third resource information, and then determine the use time of the beam corresponding to the designated resource based on the transmission time of the indication information and the designated time interval. This allows the terminal device and the network device to maintain a consistent understanding of the cross-carrier beam use time, ensures the integrity of the beam, reduces the impact on communication transmission, and improves the performance of beam transmission.

[0193] Referring to Fig. 8, Fig. 8 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 8, the method can include, but is not limited to, the following steps:

[0194] In step 81, receiving DCI based on the PDCCH of a first carrier to indicate a beam corresponding to a specified resource in a second carrier.

[0195] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0196] In step 82, indication information is transmitted to indicate the reception status of the DCI.

[0197] Note that, for the specific contents and implementation forms of step 81 and step 82, the explanations of other embodiments of the present disclosure can be referred to, and therefore the explanations are omitted here.

[0198] In step 83, in response to the SCS in the third resource information being equal to or greater than the SCS in the second resource information, a specified time interval is determined based on the SCS in the second resource information and / or the SCS in the third resource information.

[0199] Optionally, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval may be determined based on the SCS in the second resource information.

[0200] For example, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval is regulated by a protocol or set by a network device to be related to the SCS in the second resource information. For example, if the specified time interval is N symbols and the SCS in the second resource information is 15 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 15 KHz, and if the SCS in the second resource information is 60 kHz, the corresponding specified time interval is the time length occupied by N symbols when the SCS is 60 KHz.

[0201] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the correspondence between the SCS in the second resource information and the specified time interval may be regulated by a protocol or set by a network device.

[0202] Thus, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the terminal device can determine the corresponding designated time interval based on the SCS in the second resource information, thereby allowing the terminal device and the network device to maintain a consistent understanding of the designated time interval, and providing a guarantee for beam-based transmission.

[0203] Alternatively, when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval may be determined based on the SCS in the third resource information. For specific content and implementation, the description of other embodiments of the present disclosure may be referred to, and the description will be omitted here.

[0204] Alternatively, if the SCS in the third resource information is equal to or greater than the SCS in the second resource information, the specified time interval may be determined according to the SCS in the second resource information and the SCS in the third resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0205] In step 84, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0206] For the specific content and implementation form of step 84, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanation will be omitted here.

[0207] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the specified resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then transmit indication information to indicate the reception status of the DCI to the network device, determine the specified time interval based on the second resource information and / or the third resource information when the SCS in the third resource information is equal to or greater than the SCS in the second resource information, and determine the use time of the beam corresponding to the specified resource based on the transmission time of the indication information and the specified time interval. This allows the terminal device and the network device to maintain a consistent understanding of the cross-carrier beam use time, ensures beam consistency, reduces the impact on communication transmission, and improves performance by beam transmission.

[0208] Referring to Fig. 9, Fig. 9 is a schematic flowchart of a cross-carrier beam usage time determination method provided by an embodiment of the present disclosure, which is executed by a terminal device. As shown in Fig. 9, the method can include, but is not limited to, the following steps:

[0209] In step 91, a DCI is received based on a PDCCH of a first carrier to indicate a beam corresponding to a specified resource in a second carrier.

[0210] For the specific content of the designated resource and the method of determining the designated resource, etc., refer to the descriptions of other embodiments of the present disclosure, and the description will be omitted here.

[0211] In step 92, indication information is transmitted to indicate the reception status of the DCI.

[0212] Note that, for the specific contents and implementation forms of steps 91 and 92, the explanations of other embodiments of the present disclosure can be referred to, and therefore the explanations are omitted here.

[0213] In step 93, in response to the SCS in the first resource information being smaller than the SCS in the second resource information, a first sub-time in the specified time interval is determined based on the SCS in the second resource information and / or the SCS in the third resource information.

[0214] Optionally, if the SCS in the third resource information is smaller than the SCS in the second resource information, the first sub-time in the specified time interval can be determined based on the SCS in the second resource information.

[0215] For example, when the SCS in the third resource information is smaller than the SCS in the second resource information, the correspondence between the SCS in the second resource information and the first sub-time in the designated time interval is regulated by a protocol or set by the network device. This allows the terminal device to determine the first sub-time in the corresponding designated time interval based on the SCS in the second resource information. This allows the terminal device and the network device to maintain a consistent understanding of the first sub-time in the designated time interval, providing a guarantee for beam-based transmission.

[0216] Alternatively, if the SCS in the third resource information is smaller than the SCS in the second resource information, the specified time interval may be determined based on the SCS in the third resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0217] Alternatively, if the SCS in the third resource information is smaller than the SCS in the second resource information, the specified time interval may be determined according to the SCS in the second resource information and the SCS in the third resource information. For specific content and implementation, refer to the description of other embodiments of the present disclosure, and description is omitted here.

[0218] In step 94, a second sub-time in the specified time interval is determined based on the SCS in the second resource information and the SCS in the third resource information.

[0219] For example, the correspondence between the SCS in the third resource information, the SCS in the second resource information, and the second sub-time in the specified time interval may be regulated by a protocol or set by a network device. This allows the terminal device to determine the second sub-time in the corresponding specified time interval based on the SCS in the third resource information and the SCS in the second resource information. This allows the terminal device and the network device to maintain a consistent understanding of the second sub-time in the specified time interval, providing a guarantee for beam-based transmission.

[0220] Optionally, in the present disclosure, the second sub-time may be directly proportional to the SCS in the second resource information and inversely proportional to the SCS in the third resource information.

[0221] Alternatively, the first sub-time may be an integer number of time units and the second sub-time may also be an integer number of time units.

[0222] Here, the time unit may be at least one of a slot, a microslot, and a symbol, and is not limited in this disclosure.

[0223] In addition, the first sub-time may include an integer number of slots, or the first sub-time may include an integer number of microslots, or the first sub-time may include an integer number of symbols, or the first sub-time may include an integer number of slots and an integer number of microslots, or the first sub-time may include an integer number of slots and an integer number of symbols, or the first sub-time may include an integer number of microslots and an integer number of symbols, or the first sub-time may include an integer number of slots, an integer number of microslots and an integer number of symbols.

[0224] Also, the second sub-time may include an integer number of slots, or the second sub-time may include an integer number of microslots, or the second sub-time may include an integer number of symbols, or the second sub-time may include an integer number of slots and an integer number of microslots, or the second sub-time may include an integer number of slots and an integer number of symbols, the second sub-time may include an integer number of microslots and an integer number of symbols, or the second sub-time may include an integer number of slots, an integer number of microslots and an integer number of symbols.

[0225] It should be noted that the time units included in the first sub-time and the second sub-time may be any combination of the above, for example, the first sub-time includes an integer number of symbols and the second sub-time includes an integer number of symbols, or, for example, the first sub-time includes an integer number of microslots and the second sub-time includes an integer number of symbols, etc., and are not limited in this disclosure.

[0226] Thus, the specified time interval may include at least one of the following types, and is not limited by this disclosure: an integer number of slots, an integer number of microslots, and an integer number of symbols.

[0227] In step 95, the usage time of the beam corresponding to the specified resource in the second carrier is determined based on the transmission time of the instruction information and the specified time interval.

[0228] For the specific content and implementation form of step 95, the explanations of other embodiments of the present disclosure may be referred to, and therefore the explanation will be omitted here.

[0229] By implementing the embodiment of the present disclosure, the terminal device can know the beam corresponding to the specified resource in the second carrier by receiving DCI based on the PDCCH of the first carrier, then transmit the indication information to indicate the reception state of the DCI to the network device, and when the SCS in the third resource information is smaller than the SCS in the second resource information, determine the first sub-time and the second sub-time in the specified time interval based on the SCS in the second resource information and / or the SCS in the third resource information, and determine the use time of the beam corresponding to the specified resource based on the transmission time of the indication information and the specified time interval. This allows the terminal device and the network device to have a consistent understanding of the cross-carrier beam use time, ensures the integrity of the beam, reduces the impact on communication transmission, and improves the performance of the beam transmission.
