[0131] In some embodiments, each frequency band combination includes multiple frequency bands, and these multiple frequency bands support simultaneous DMRS bundling. Alternatively, it can be understood that the multiple frequency bands included in each frequency band combination support multi-sequence retransmission. Optionally, multi-sequence retransmission refers to multiple transmissions of PUCCH or PUSCH, and may also include increasing the interval between repeated transmissions. In some embodiments, the first maximum duration is used to indicate the maximum duration for performing multi-sequence retransmission simultaneously on multiple frequency bands included in the corresponding frequency band combination.

[0132] In some embodiments, the first maximum duration is a numerical value. For example, the first maximum duration corresponding to band combination 1 is 2 slots (time slots), the first maximum duration corresponding to band combination 2 is 4 slots, the first maximum duration corresponding to band combination 3 is 8 slots,

[0133] In some embodiments, the first maximum duration is indicated by a duration identifier, and the first maximum duration and the duration identifier are in a one-to-one correspondence. Optionally, the duration identifier is represented by a certain number of bits. For example, if the duration identifier is represented by 2 bits, there are four types of duration identifiers, namely 00, 01, 10, and 11. For another example, if the duration identifier is represented by 3 bits, there are eight types of duration identifiers, namely 000, 001, 010, 011, 100, 110, 101, and 111.

[0134] In the embodiment of the present disclosure, one duration identifier corresponds to one first maximum duration, and one frequency band combination also corresponds to one first maximum duration, that is, the duration identifier and the frequency band combination are also in a one-to-one correspondence.

[0135] For example, duration identifier 1 corresponds to the first maximum duration 1, duration identifier 2 corresponds to the first maximum duration 2, duration identifier 3 corresponds to the first maximum duration 3, and duration identifier 4 corresponds to the first maximum duration 4, and duration identifier 1 corresponds to frequency band combination 1, duration identifier 2 corresponds to frequency band combination 2, duration identifier 3 corresponds to frequency band combination 3, and duration identifier 4 corresponds to frequency band combination 4. Therefore, the first maximum duration of frequency band combination 1 is the first maximum duration 1, the first maximum duration of frequency band combination 2 is the first maximum duration 2, the first maximum duration of frequency band combination 3 is the first maximum duration 3, and the first maximum duration of frequency band combination 4 is the first maximum duration 4.

[0136] In some embodiments, the first information is further used to indicate that the frequency band combination of the terminal has the capability to support simultaneous transmission of the DMRS bundling. In the embodiment of the present disclosure, if the terminal sends the first information, it indicates that the frequency band combination of the terminal has the capability to support simultaneous transmission of the DMRS bundling.

[0137] In some embodiments, the first information is further used to indicate that the frequency band combination of the terminal has the capability to support multiple simultaneous retransmissions. In the embodiment of the present disclosure, if the terminal sends the first information, it indicates that the frequency band combination of the terminal has the capability to support multiple simultaneous retransmissions.

[0138] It should be noted that the disclosed embodiments are described using the example of a terminal sending the first information. In another embodiment, the terminal may not send the first information. If the terminal does not send the first information, it indicates that the terminal does not support simultaneous DMRS bundling across multiple frequency bands included in the frequency band combination. Alternatively, it can be understood that if the terminal does not send the first information, it indicates that the terminal does not support simultaneous multi-time retransmission across multiple frequency bands included in the frequency band combination.

[0139] In some embodiments, the terminal supports different numbers of TAGs, and the first information is used to indicate the first maximum duration of at least one frequency band combination, including: the first information is used to indicate the first maximum duration corresponding to each of the frequency band combinations under the supported TAG.

[0140] Optionally, the terminal may support a single TAG, or the terminal may also support two TAGs, which is not limited in the embodiments of the present disclosure.

[0141] In some embodiments, the terminal indicates the first maximum duration of each frequency band combination for different numbers of TAGs. Optionally, in the case where the terminal supports a single TAG, the terminal indicates the first maximum duration of each frequency band combination; in the case where the terminal supports two TAGs, the terminal indicates the first maximum duration of each frequency band combination. For example, if the terminal has three frequency band combinations, namely, frequency band combination 1, frequency band combination 2, and frequency band combination 3, and needs to indicate the maximum duration, then in the case of a single TAG, the maximum duration of frequency band combination 1 is the first maximum duration 1, the maximum duration of frequency band combination 2 is the first maximum duration 2, and the maximum duration of frequency band combination 3 is the first maximum duration 3. In the case of two TAGs, the maximum duration of frequency band combination 1 is the first maximum duration 4, the maximum duration of frequency band combination 2 is the first maximum duration 5, and the maximum duration of frequency band combination 3 is the first maximum duration 6.

[0142] In some embodiments, a tag identifier is used to distinguish different numbers of tags. Optionally, the tag identifier and the number of tags are in a one-to-one correspondence. For example, a one-bit tag identifier is used. If the tag identifier is 0, the corresponding number of tags is 1; if the tag identifier is 1, the corresponding number of tags is 2.

[0143] In an embodiment of the present disclosure, when the terminal sends the first information, the first information indicates a first maximum duration of each frequency band combination under conditions of different numbers of TAGs.

[0144] It should be noted that, if the terminal only supports single TAG, the terminal can directly report the first maximum duration of each frequency band combination, and the terminal supports single TAG by default.

[0145] In some embodiments, the first information further includes a modulation order, where the modulation order refers to a maximum modulation order supported by the terminal under the first maximum duration.

[0146] Optionally, the modulation order includes any one of BPSK, QPSK, 16QAM, and 64QAM, wherein the modulation orders of BPSK, QPSK, 16QAM, and 64QAM increase in sequence.

[0147] For example, if the modulation order included in the first information is 64QAM, it means that the maximum modulation order supported by the terminal under the first maximum duration is 64QAM, which can also be understood as the terminal supporting any one of BPSK, QPSK, 16QAM, and 64QAM. For another example, if the modulation order included in the first information is 16QAM, it means that the maximum modulation order supported by the terminal under the first maximum duration is 16QAM, which can also be understood as the terminal supporting any one of BPSK, QPSK, and 16QAM.

[0148] Step S2102: The network device receives first information.

[0149] After receiving the first information, the network device can determine the first maximum duration of the at least one frequency band combination indicated by the terminal.

[0150] Among them, step S2102 is similar to step S2101 in the above embodiment and will not be repeated here.

[0151] Step S2103: The terminal sends third information.

[0152] In some embodiments, the third information is used to indicate a second maximum duration of each frequency band, and the second maximum duration is used to indicate a maximum duration of a DMRS bunding transmitted in each frequency band.

[0153] In the embodiment of the present disclosure, the terminal may also support DMRS bundling for transmission in each separate frequency band, and thus the terminal indicates this through the third information.

[0154] In some embodiments, the third information is used to indicate a second maximum duration of each frequency band, and the second maximum duration is used to indicate a maximum duration of multi-time sequence retransmission for each frequency band.

[0155] In some embodiments, the third information is used to indicate a second maximum duration of each individual carrier.

[0156] In some embodiments, the third information is used to indicate a second maximum duration corresponding to each of the frequency band combinations under a supported TAG.

[0157] Optionally, the terminal may support a single TAG, or the terminal may also support two TAGs, which is not limited in the embodiments of the present disclosure.

[0158] In some embodiments, the terminal indicates the second maximum duration of each frequency band combination for different numbers of TAGs. Optionally, in the case where the terminal supports single TAG, the terminal indicates the second maximum duration of each frequency band combination; in the case where the terminal supports two TAGs, the terminal indicates the second maximum duration of each frequency band combination. For example, if the terminal has three frequency band combinations, namely, frequency band combination 1, frequency band combination 2, and frequency band combination 3, and needs to indicate the maximum duration, then in the case of single TAG, the maximum duration of frequency band combination 1 is the second maximum duration 1, the maximum duration of frequency band combination 2 is the second maximum duration 2, and the maximum duration of frequency band combination 3 is the second maximum duration 3. In the case of two TAGs, the maximum duration of frequency band combination 1 is the second maximum duration 4, the maximum duration of frequency band combination 2 is the second maximum duration 5, and the maximum duration of frequency band combination 3 is the second maximum duration 6.

[0159] In some embodiments, a tag identifier is used to distinguish different numbers of tags. Optionally, the tag identifier and the number of tags are in a one-to-one correspondence. For example, a one-bit tag identifier is used. If the tag identifier is 0, the corresponding number of tags is 1; if the tag identifier is 1, the corresponding number of tags is 2.

[0160] In the embodiment of the present disclosure, when the terminal sends the third information, the third information indicates the second maximum duration of each frequency band combination when there are different numbers of TAGs.

[0161] It should be noted that, if the terminal only supports single TAG, the terminal can directly report the second maximum duration of each frequency band combination. The terminal supports single TAG by default.

[0162] In some embodiments, the third information further includes a modulation order, where the modulation order refers to a maximum modulation order supported by the terminal under the second maximum duration.

[0163] Optionally, the modulation order includes any one of BPSK, QPSK, 16QAM, and 64QAM, wherein the modulation orders of BPSK, QPSK, 16QAM, and 64QAM increase in sequence.

[0164] For example, if the modulation order included in the third information is 64QAM, it means that the maximum modulation order supported by the terminal during the second maximum duration is 64QAM, which can also be understood as the terminal supporting any one of BPSK, QPSK, 16QAM, and 64QAM. For another example, if the modulation order included in the third information is 16QAM, it means that the maximum modulation order supported by the terminal during the second maximum duration is 16QAM, which can also be understood as the terminal supporting any one of BPSK, QPSK, and 16QAM.

[0165] It should be noted that the third information is the same as the first information, that is, one piece of information has the functions of both the first information and the third information. Alternatively, the third information is different from the first information.

[0166] Step S2104: The network device receives the third information.

[0167] After receiving the third information, the network device can determine the second maximum duration of the at least one frequency band indicated by the terminal.

[0168] Among them, step S2104 is similar to step S2103 in the above embodiment and will not be repeated here.

[0169] It should be noted that the execution order of step S2101 and step S2103 in the embodiment of the present disclosure is not limited. Step S2103 can also be executed first, and then step S2101. Alternatively, step S2101 and step S2103 can be executed simultaneously.

[0170] It should be noted that the execution order of step S2102 and step S2104 in the embodiment of the present disclosure is not limited. Step S2104 can also be executed first, and then step S2102. Alternatively, step S2102 and step S2104 can be executed simultaneously.

[0171] It should be noted that the first information and the third information in the above embodiment may be the same information, that is, the same information has the functions of both the first information and the third information, which is not limited in the embodiment of the present disclosure.

[0172] Step S2105: The network device sends the second information.

[0173] In some embodiments, the second information is used to configure a first time domain window of at least one of the frequency band combinations, the length of the first time domain window is not greater than the first maximum duration corresponding to the frequency band combination, and the multiple frequency bands included in the frequency band combination simultaneously transmit DMRS bunding within the first time domain window.

[0174] In the embodiment of the present disclosure, each frequency band combination corresponds to a first time domain window, and the length of the first time domain window is not greater than the first maximum duration corresponding to the frequency band combination.

[0175] In some embodiments, if the terminal reports that it supports different numbers of TAGs, the network device configures a certain number of TAGs for the terminal, and then indicates the first maximum duration of each frequency band combination under the number of TAGs through the second information.

[0176] Optionally, the second information is also used to configure a fixed number of TAGs for the terminal.

[0177] In some embodiments, the name of the second information is not limited, and it can be, for example, configuration information, downlink information, etc.

[0178] Step S2106: The terminal receives the second information.

[0179] Step S2107: The network device sends fourth information.

[0180] In some embodiments, the fourth information is used to configure a second time domain window for each frequency band, the length of the second time domain window is not greater than the second maximum duration corresponding to each frequency band, and each frequency band transmits DMRS bunding within the second time domain window.

[0181] In some embodiments, the fourth information is used to configure a second time domain window for each of the frequency bands, the length of the second time domain window is not greater than the second maximum duration corresponding to each of the frequency bands, and each of the frequency bands transmits DMRS bunding within the second time domain window.

[0182] In the embodiment of the present disclosure, each frequency band corresponds to a second time domain window, and the length of the second time domain window is not greater than the second maximum duration corresponding to the frequency band.

[0183] In some embodiments, if the terminal reports that it supports different numbers of TAGs, the network device configures a certain number of TAGs for the terminal, and then indicates the second maximum duration of each frequency band under the number of TAGs through the fourth information.

[0184] Optionally, the fourth information is also used to configure a fixed number of TAGs for the terminal.

[0185] In some embodiments, the name of the fourth information is not limited, and it can be, for example, configuration information, downlink information, etc.

[0186] It should be noted that the second information and the fourth information in the embodiment of the present disclosure are the same information, which can also be understood as one information having the functions of the second information and the fourth information. Alternatively, the second information and the fourth information are different information.

[0187] Step S2108: The terminal receives the fourth information.

[0188] It should be noted that the execution order of step S2105 and step S2107 in the embodiment of the present disclosure is not limited. Step S2107 can also be executed first, and then step S2105. Alternatively, step S2105 and step S2107 can be executed simultaneously.

[0189] It should be noted that the execution order of step S2106 and step S2108 in the embodiment of the present disclosure is not limited. Step S2108 can also be executed first, and then step S2106. Alternatively, step S2106 and step S2108 can be executed simultaneously.

[0266] In some embodiments, under the condition of a frequency band combination, the terminal may indicate to the base station the maximum duration of the DMRS bundling of the simultaneous transmission of the combination, such as reporting the concurrent maxDurationDMRS-Bundling capability, which is indicated per band combination (i.e., according to the frequency band combination) (Note: the existing protocol already has the capability of reporting per band (according to the frequency band), which needs to be distinguished here).

[0267] In one embodiment, the maximum duration is one of 2 slots, 4 slots, 8 slots, 16 slots, and 32 slots.

[0268] In some embodiments, if the concurrent maxDurationDMRS-Bundling capability is not reported, it may be defaulted to indicate that simultaneous DMRS bundling transmission is not supported under the frequency band combination conditions, that is, the base station cannot simultaneously configure DMRS bundling transmission on multiple frequency bands or multiple carriers within a certain time period.

[0269] In some embodiments, the base station configures the terminal according to the instruction of the terminal and transmits the TDW (Time Domain Window) length of the DMRS bundling in the combination, and the length is less than or equal to the reported maximum duration capability of the DMRS bundling.

[0270] In another embodiment, two capabilities may be reported separately according to different TAGs, one applicable to single TAG and the other applicable to two TAGs. The reporting method may be the same as in Example 1, for example:

[0271] The maximum duration of cocurrent maxDurationDMRS-Bundling_single TAG is 16 slots

[0272] The maximum duration of the cocurrent maxDurationDMRS-Bundling_two TAG is 8 slots.

[0273] In some embodiments, if only one is reported, it can be assumed that the above reporting is only applicable to single TAG.

[0274] In some embodiments, the base station determines the maximum duration capability of the DMRS bundling based on whether the terminal is configured with a single TAG or a two TAG when configuring the length of the TDW (Time Domain Window) of the combination of the terminal according to the instruction of the terminal, thereby ensuring that the length of the TDW is less than or equal to the corresponding maximum duration capability.

[0275] In another embodiment, the terminal reports the corresponding maximum duration of the simultaneously transmitted DMRS bundling of the combination according to the TAG status (ie, single TAG or two TAG) currently configured by the base station.

[0276] In another embodiment, when indicating the maximum duration of the simultaneously transmitted DMRS bundling, the terminal also indicates the modulation order.

[0277] The modulation order is the maximum modulation order that the terminal can support while supporting the reported maximum duration of the DMRS bundling transmitted simultaneously. In one embodiment, the modulation order is one of {BPSK, QPSK, 16QAM, 64QAM}.

[0278] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
