[0036] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0037] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0039] Technologies, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods and equipment should be considered part of the authorization specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] In some embodiments, the terminal may use two sets of transmitters to transmit uplink data. For example, one set of transmitters is fixed to send data at 3.5 GHz, and the other set is dynamically switched to send data on two carriers, 3.5 GHz and 2.1 GHz.

[0043] For example, in a super uplink method based on SUL, a terminal sends data on two carriers of high frequency and low frequency by means of TDM (Time-Division Multiplexing) technology, that is, data is sent on only one carrier at a time.

[0044] For example, in Option 1 (first mode) of the super uplink method based on UL CA, the terminal sends data on two carriers, high and low frequencies, in a TDM manner, that is, data is sent on only one carrier at a time.

[0045] For example, in Option 2 (first mode) of the super uplink method based on UL CA, the terminal supports sending data on both high-frequency and low-frequency carriers simultaneously.

[0046] In some embodiments, in NR (New Radio) dual-band (3 carriers in total) collaborative networking, one band contains a single carrier and the other band contains two carriers. The terminal uses two sets of transmitters and supports dynamic switching of two sets of transmitters on the 3.5GHz (including two carriers) and 2.1GHz (1 carrier) bands. There is no technical solution to improve uplink coverage in the case of being able to send data on two bands.

[0047] In view of the above technical problems, the present disclosure proposes a method for transmitting uplink data. For example, the technical solution of the present disclosure can be implemented through the following embodiments.

[0048] Figure 1 A flow chart showing some embodiments of the uplink data transmission method of the present disclosure.

[0049] like Figure 1 As shown, in step 110, the uplink multi-carrier transmission method currently adopted by the terminal is obtained, and the terminal has multiple transmitters and can transmit uplink data on multiple frequency bands.

[0050] In step 120, the transmitter states of the plurality of transmitters of the terminal are determined, where the transmitter states include the correspondence between the plurality of transmitters and the plurality of frequency bands.

[0051] In step 130, according to the transmitter status, the corresponding transmitter is called to transmit uplink data of different frequency bands.

[0052] In some embodiments, the technical solution of the present disclosure may also include Figure 2 The embodiments in .

[0053] Figure 2 Flowcharts showing other embodiments of the uplink data transmission method of the present disclosure.

[0054] like Figure 2 As shown, in step 210, the corresponding ports used for transmitting uplink data of different frequency bands are determined according to the currently used uplink multi-carrier transmission method.

[0055] In some embodiments, a transmitter state between the plurality of transmitters and the plurality of frequency bands is determined based on whether each of the plurality of transmitters supports switching between the plurality of frequency bands.

[0056] For example, when the currently adopted uplink multi-carrier transmission method is the first mode of SUL or UL CA, and the first transmitter of the terminal supports switching between the first frequency band and the second frequency band, and the second transmitter is fixed in the second frequency band, the first transmitter state and the second transmitter state are established.

[0057] The first transmitter state includes the first transmitter transmitting data in the first frequency band and the second transmitter transmitting data in the second frequency band; the second transmitter state includes the first transmitter and the second transmitter transmitting data in the second frequency band.

[0058] For example, a terminal transmits data based on SUL or UL CA option 1, and its two transmitters support a 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers. The 1Tx-2Tx switching mode indicates that the first transmitter supports switching between frequency band 1 and frequency band 2, and the second transmitter is fixed at frequency band 2.

[0059] In this case, the port mapping relationship between the two transmitters and the uplink transmission port is:

[0060] The first transmitter state is 1T+1T, indicating that the first transmitter transmits data in frequency band 1 and the second transmitter transmits data in frequency band 2; the second transmitter state is 0T+2T, indicating that the first transmitter and the second transmitter transmit data in frequency band 2.

[0061] The number of ports on each frequency band corresponds to the transmitter status of the same line. For example, 1P+(0P+0P) means that the number of ports on a single carrier in frequency band 1 is 1, and the number of ports on both carriers in frequency band 2 is 0; 0P+(1P+2P) means that the number of ports on a single carrier in frequency band 1 is 0, the number of ports on one carrier in frequency band 2 is 1, and the number of ports on the other carrier is 2, and so on.

[0062] In some embodiments, when the currently adopted uplink multi-carrier transmission method is the first mode of SUL or CA, and the first transmitter and the second transmitter of the terminal both support switching between the first frequency band and the second frequency band, the first transmitter state and the second transmitter state are established.

[0063] The first transmitter state includes the first transmitter and the second transmitter transmitting data in the second frequency band; the second transmitter state includes the first transmitter and the second transmitter transmitting data in the first frequency band.

[0064] For example, the terminal transmits data based on SUL or UL CA option 1, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, frequency band 2 includes two carriers, and the 2Tx-2Tx switching mode indicates that both the first transmitter and the second transmitter support switching between frequency band 1 and frequency band 2.

[0065] In this case, the port mapping relationship between the two transmitters and the uplink transmission port is:

[0066] The first transmitter state is 0T+2T, the second transmitter state is 2T+0T, and the number of ports on each frequency band corresponds to the transmitter state of the same line.

[0067] In some embodiments, when the currently adopted uplink multi-carrier transmission method is the second mode of CA, and the first transmitter of the terminal supports switching between the first frequency band and the second frequency band, and the second transmitter is fixed in the second frequency band, the first transmitter state and the second transmitter state are established.

[0068] The first transmitter state includes the first transmitter transmitting data in the first frequency band and the second transmitter transmitting data in the second frequency band; the second transmitter state includes the first transmitter and the second transmitter transmitting data in the second frequency band.

[0069] For example, the terminal transmits data based on UL CA option 2, and its two transmitters support a 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0070] In this case, the port mapping relationship between the two transmitters and the uplink transmission port is:

[0071] The first transmitter state is 1T+1T, the second transmitter state is 0T+2T, and the number of ports on each frequency band corresponds to the transmitter state of the same line.

[0072] In some embodiments, when the currently adopted uplink multi-carrier transmission method is the second mode of CA, and the first transmitter and the second transmitter of the terminal both support switching between the first frequency band and the second frequency band, a first transmitter state, a second transmitter state and a third transmitter state are established.

[0073] The first transmitter state includes the first transmitter transmitting data in the first frequency band and the second transmitter transmitting data in the second frequency band; the second transmitter state includes the first transmitter and the second transmitter transmitting data in the second frequency band; the third transmitter state includes the first transmitter and the second transmitter transmitting data in the first frequency band.

[0074] For example, the terminal transmits data based on UL CA option 2, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0075] In this case, the port mapping relationship between the two transmitters and the uplink transmission port is:

[0076] The first transmitter state is 1T+1T, the second transmitter state is 0T+2T, and the third mapping relationship is 2T+0T. The number of ports on each frequency band corresponds to the transmitter state of the same line.

[0077] In step 220, according to the port mapping relationship, the corresponding port is called to transmit uplink data of different frequency bands.

[0078] In some embodiments, Figure 3 The embodiment in implements step 120 and step 130.

[0079] Figure 3 Flowcharts showing other embodiments of the uplink data transmission method of the present disclosure.

[0080] like Figure 3 As shown, in step 1210, multiple transmitter states are determined according to the currently adopted uplink multi-carrier transmission method. For example, the current transmitter state can be determined according to at least one of the following three conditions: condition 1, the uplink multi-carrier transmission method adopted by the terminal; condition 2, whether each of the multiple transmitters supports switching between multiple frequency bands; condition 3, the number of carriers included in each frequency band.

[0081] In some embodiments, the terminal transmits data based on SUL or UL CA option 1, and its two transmitters support 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0082] For example, the initial state (current transmitter state) of the terminal transmitter configuration may be: frequency band 1 corresponds to 1 transmitter, frequency band 2 corresponds to 1 transmitter; or frequency band 1 corresponds to 0 transmitters, frequency band 2 corresponds to two transmitters.

[0083] In some embodiments, the terminal transmits data based on SUL or UL CA option 1, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0084] For example, the initial state of the terminal's transmitter configuration can be: frequency band 1 corresponds to 1 transmitter, frequency band 2 corresponds to 1 transmitter

[0085] In some embodiments, the terminal transmits data based on UL CA option 2, and its two transmitters support a 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0086] For example, the initial state of the transmitter configuration of the terminal may be: frequency band 1 corresponds to 1 transmitter, and frequency band 2 corresponds to 1 transmitter.

[0087] In some embodiments, the terminal transmits data based on UL CA option 2, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0088] For example, the initial state of the transmitter configuration of the terminal may be: frequency band 1 corresponds to 1 transmitter, and frequency band 2 corresponds to 1 transmitter.

[0089] In step 1310, according to the relevant situation of the frequency band used for the next transmission, it is determined whether to switch the current transmitter state to another transmitter state among the multiple transmitter states as the transmitter state based on the next transmission. The current transmitter state is the mapping relationship based on this transmission.

[0090] In some embodiments, whether to switch the current transmitter state to another transmitter state among the multiple transmitter states may be determined according to the number of carriers in the frequency band used for the next transmission or the number of ports on the carriers.

[0091] For example, when the number of carriers in the frequency band used for the next transmission is greater than or equal to the number of transmitters corresponding to the frequency band in the current transmitter state, the current transmitter state is switched to another transmitter state. In other mapping relationships, the number of transmitters corresponding to the frequency band is greater than or equal to the number of carriers.

[0092] For example, when the number of ports on the carrier in the frequency band used for the next transmission is greater than or equal to the number of transmitters corresponding to the frequency band in the current transmitter state, the current transmitter state is switched to another transmitter state. In other mapping relationships, the number of transmitters corresponding to the frequency band is greater than or equal to the number of ports.

[0093] In some embodiments, the terminal transmits data based on SUL or UL CA option 1, and its two transmitters support 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0094] For example, the current state (transmitter state) of the transmitter of the terminal is: one transmitter corresponds to frequency band 1, and one transmitter corresponds to frequency band 2. The frequency band used for the next transmission is: at least one carrier in frequency band 2 has transmission.

[0095] In this case, the transmitter of the terminal is switched, and the state after switching (other transmitter states) is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters, that is, the original 1 transmitter supporting frequency band switching corresponding to frequency band 1 is switched to frequency band 2; no switching occurs in other cases.

[0096] For example, the current state of the terminal transmitter is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters. The frequency band used for the next transmission is: there is 1-port transmission on the carrier in frequency band 1.

[0097] In this case, the terminal transmitter switches, and the status after switching is: frequency band 1 corresponds to 1 transmitter, and frequency band 2 corresponds to 1 transmitter, that is, the 1 transmitter that supports frequency band switching that originally corresponds to frequency band 2 switches to frequency band 1; no switching occurs in other cases.

[0098] In some embodiments, the terminal transmits data based on SUL or UL CA option 1, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0099] For example, the current state of the transmitter of the terminal is: two transmitters correspond to frequency band 1, and zero transmitters correspond to frequency band 2. The frequency band used for the next transmission is: at least one carrier in frequency band 2 has transmission.

[0100] In this case, the transmitter of the terminal is switched, and the status after switching is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters, that is, the original 1 transmitter supporting frequency band switching corresponding to frequency band 1 is switched to frequency band 2; no switching occurs in other cases.

[0101] For example, the current state of the terminal transmitter is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters. The frequency band used for the next transmission is: there is 1-port transmission on the carrier in frequency band 1.

[0102] In this case, the terminal transmitter switches, and the status after switching is: frequency band 1 corresponds to 2 transmitters, and frequency band 2 corresponds to 0 transmitters, that is, the two transmitters that originally correspond to frequency band 2 and support frequency band switching are switched to frequency band 1; no switching occurs in other cases.

[0103] In some embodiments, the terminal transmits data based on UL CA option 2, and its two transmitters support a 1Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0104] For example, the current state of the transmitter of the terminal is: one transmitter corresponds to frequency band 1, and one transmitter corresponds to frequency band 2. The frequency band used for the next transmission is: at least one carrier in frequency band 2 has 2-port transmission.

[0105] In this case, the transmitter of the terminal is switched, and the status after switching is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters, that is, the original 1 transmitter supporting frequency band switching corresponding to frequency band 1 is switched to frequency band 2; no switching occurs in other cases.

[0106] For example, the current state of the terminal transmitter is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters. The frequency band used for the next transmission is: there is 1-port transmission on the carrier in frequency band 1.

[0107] In this case, the terminal transmitter switches, and the status after switching is: frequency band 1 corresponds to 1 transmitter, and frequency band 2 corresponds to 1 transmitter, that is, the 1 transmitter that supports frequency band switching that originally corresponds to frequency band 2 switches to frequency band 1; no switching occurs in other cases.

[0108] In some embodiments, the terminal transmits data based on UL CA option 2, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0109] For example, the current state of the terminal's transmitter is: 1 transmitter corresponds to frequency band 1, and 1 transmitter corresponds to frequency band 2. The frequency band used for the next transmission is: there is 2-port transmission on the carrier in frequency band 1.

[0110] In this case, the transmitter of the terminal is switched, and the status after switching is: frequency band 1 corresponds to 2 transmitters, and frequency band 0 corresponds to two transmitters, that is, the 1 transmitter supporting frequency band switching that originally corresponds to frequency band 2 is switched to frequency band 2; no switching occurs in other cases.

[0111] For example, the frequency band used for the next transmission is as follows: there is 2-port transmission on at least one carrier in frequency band 2.

[0112] In this case, the terminal transmitter switches, and the status after switching is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to 2 transmitters, that is, the 1 transmitter that supports frequency band switching that originally corresponds to frequency band 1 switches to frequency band 2; no switching occurs in other cases.

[0114] For example, the current state of the transmitter of the terminal is: 2 transmitters corresponding to frequency band 1, and 0 transmitters corresponding to frequency band 2. The frequency band related situation used for the next transmission is: there is 1-port transmission on at least one carrier in frequency band 2.

No switching occurs in other cases.

[0116] State 1 or state 2 may be fixed by a protocol; the base station may instruct the terminal to select state 1 or state 2 through signaling; or the terminal may determine state 1 or state 2 by itself.

[0117] For example, the frequency band used for the next transmission is as follows: there is 2-port transmission on at least one carrier in frequency band 2.

[0118] In this case, the terminal transmitter switches, and the status after switching is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to 2 transmitters, that is, the two transmitters that originally correspond to frequency band 1 and support frequency band switching are switched to frequency band 2; no switching occurs in other cases.

[0119] In some embodiments, the terminal transmits data based on UL CA option 2, and its two transmitters support a 2Tx-2Tx switching mode between two frequency bands. Frequency band 1 includes one carrier, and frequency band 2 includes two carriers.

[0120] For example, the current state of the terminal's transmitter is: frequency band 1 corresponds to 0 transmitters, and frequency band 2 corresponds to two transmitters. The frequency band used for the next transmission is: there is 1-port transmission on at least one carrier in frequency band 1.

[0121] In this case, the transmitter of the terminal is switched, and the state after the switching is: state 1, frequency band 1 corresponds to 1 transmitter, frequency band 2 corresponds to 1 transmitter; or state 2, frequency band 1 corresponds to 2 transmitters, frequency band 2 corresponds to 0 transmitters. No switching occurs in other cases.

[0122] State 1 or state 2 may be fixed by a protocol; the base station may instruct the terminal to select state 1 or state 2 through signaling; or the terminal may determine state 1 or state 2 by itself.

[0123] For example, the frequency band used for the next transmission is as follows: there is 2-port transmission on at least one carrier in frequency band 1.

[0124] In this case, the terminal transmitter is switched, and the status after the switching is: frequency band 1 corresponds to two transmitters, and frequency band 2 corresponds to 0 transmitters; no switching occurs in other cases.

[0125] In the above embodiment, according to the previously adopted uplink multi-carrier transmission method, the transmitter states between multiple transmitters and multiple frequency bands adopted by the terminal are determined, and dynamic switching of multiple transmitters on multiple frequency bands can be realized. In this way, the uplink capacity and uplink coverage performance can be improved, thereby improving the communication quality.
