In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In some embodiments, the terminal may employ two sets of transmitters for transmitting uplink data. For example, one set of transmitter is fixed at 3.5GHz for transmitting data, and the other set of transmitter is dynamically switched between two carriers of 3.5GHz and 2.1GHz for transmitting data.

For example, in the SUL-based super uplink method, the terminal transmits data on two carriers of high and low frequencies in a TDM (Time-Division Multiplexing) technique, that is, only one carrier at a Time.

For example, in Option1 (first mode) of the UL CA-based super uplink method, the terminal transmits data in a TDM manner on two carriers of high and low frequencies. I.e. data is transmitted on only one carrier at the same time.

For example, in Option2 (first mode) of the UL CA-based super uplink method, the terminal supports simultaneous transmission of data on both high and low frequency carriers.

In some embodiments, in an NR (New Radio, new air interface) dual-band (total 3 carriers) cooperative networking, one band includes a single carrier, and the other band includes two carriers. The terminal adopts two sets of transmitters and supports dynamic switching of 2 sets of transmitters on two frequency bands of 3.5GHz (comprising two carriers) and 2.1GHz (1 carrier). There is no technical solution for improving uplink coverage in the case of being able to transmit data in two frequency bands.

In order to solve the above technical problem, the present disclosure provides a method for transmitting uplink data. For example, the technical solution of the present disclosure can be realized by the following embodiments.

Fig. 1 shows a flow chart of some embodiments of the disclosed method for transmission of uplink data.

As shown in fig. 1, in step 110, an uplink multi-carrier transmission method currently adopted by a terminal is obtained, where the terminal has multiple transmitters and is capable of transmitting uplink data on multiple frequency bands.

In step 120, transmitter states of a plurality of transmitters of the terminal are determined, the transmitter states including correspondences between the plurality of transmitters and the plurality of frequency bands.

In step 130, according to the transmitter status, the corresponding transmitter is invoked to transmit uplink data of different frequency bands.

In some embodiments, aspects of the present disclosure may also include the embodiment of fig. 2.

Fig. 2 is a flowchart illustrating another embodiment of the uplink data transmission method according to the present disclosure.

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

In some embodiments, transmitter states between the plurality of transmitters and the plurality of frequency bands are determined based on whether each of the plurality of transmitters supports switching between the plurality of frequency bands.

For example, in a case where 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 to the second frequency band, the first transmitter state and the second transmitter state are established.

The first transmitter state comprises the first transmitter transmitting data in a first frequency band and the second transmitter transmitting data in a second frequency band; the second transmitter state includes the first transmitter and the second transmitter transmitting data in a second frequency band.

For example, a terminal transmits data based on SUL or UL CA option1, and its two transmitters support a 1Tx-2Tx switching pattern between two frequency bands. The frequency band 1 comprises 1 carrier, the frequency band 2 comprises two carriers, the 1Tx-2Tx switching mode indicates that the first transmitter supports switching between the frequency band 1 and the frequency band 2, and the second transmitter is fixed at the frequency band 2.

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

the state of the first transmitter is 1T +1T, which indicates that the first transmitter transmits data in a frequency band 1 and the second transmitter transmits data in a frequency band 2; the second transmitter state is 0T +2T, which indicates that the first transmitter and the second transmitter transmit data in frequency band 2.

The number of ports on each band corresponds to the state of the transmitters in the same row. For example, 1P + (0p + 0p) indicates that the number of ports on a single carrier in the frequency band 1 is 1, and the number of ports on two carriers in the frequency band 2 is 0;0P + (1p + 2p) indicates that the number of ports on a single carrier in the frequency band 1 is 0, the number of ports on one carrier in the frequency band 2 is 1, the number of ports on the other carrier is 2, and so on.

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

The first transmitter state comprises 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.

For example, a terminal transmits data based on SUL or UL CA option1, and its two transmitters support a 2Tx-2Tx switching pattern between two frequency bands. Band 1 contains 1 carrier, band 2 contains two carriers, and the 2Tx-2Tx switching pattern indicates that both the first transmitter and the second transmitter support switching between band 1 and band 2.

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 state of the transmitters in the same row.

In some embodiments, the first transmitter state and the second transmitter state are established when the currently adopted uplink multi-carrier transmission method is the second mode of CA, 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.

For example, a terminal transmits data based on UL CA option2, and its two transmitters support a 1Tx-2Tx switching pattern between two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

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 state of the transmitters in the same row.

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

The first transmitter state comprises the first transmitter transmitting data in a first frequency band and the second transmitter transmitting data in a second frequency band; the second transmitter state comprises the first transmitter and the second transmitter transmitting data in a second frequency band; the third transmitter state includes the first transmitter and the second transmitter transmitting data in the first frequency band.

For example, the terminal transmits data based on UL CA option2, and its two transmitters support a 2Tx-2Tx switching pattern between two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

the first transmitter state is 1T +1T, the second transmitter state is 0T +2T, the third mapping relationship is 2T +0T, and the number of ports on each frequency band corresponds to the state of the transmitters in the same row.

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

In some embodiments, step 120 and step 130 may be implemented by the embodiment in fig. 3.

Fig. 3 shows a flow chart of further embodiments of the disclosed method for transmitting uplink data.

As shown in fig. 3, in step 1210, a plurality of transmitter states are determined according to the currently employed uplink multi-carrier transmission method. For example, it may be according to: condition 1, an uplink multi-carrier transmission method adopted by a terminal; condition 2, whether each of the plurality of transmitters supports switching between a plurality of frequency bands; and 3, the number of carriers contained in each frequency band, and at least one of the 3 conditions determines the current transmitter state.

In some embodiments, the terminal transmits data based on SUL or UL CA option1, and its two transmitters support a 1Tx-2Tx switching pattern between the two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

For example, the initial state (current transmitter state) may be configured for the transmitter of the terminal as: frequency band 1 corresponds to 1 transmitter, and frequency band 2 corresponds to 1 transmitter; or frequency band 1 for 0 transmitters and frequency band 2 for two transmitters

In some embodiments, the terminal transmits data based on SUL or UL CA option1, and its two transmitters support a 2Tx-2Tx switching pattern between the two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

For example, the transmitter of the terminal may be configured with the initial states: frequency band 1 for 1 transmitter and frequency band 2 for 1 transmitter

In some embodiments, the terminal transmits data based on UL CA option2 and its two transmitters support a 1Tx-2Tx switching pattern between the two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

For example, the transmitter of the terminal may be configured with the initial states: band 1 corresponds to 1 transmitter and band 2 corresponds to 1 transmitter.

In some embodiments, the terminal transmits data based on UL CA option2 and its two transmitters support a 2Tx-2Tx switching pattern between the two frequency bands. Band 1 contains 1 carrier and band 2 contains two carriers.

In step 1310, it is determined whether to switch the current transmitter state to another transmitter state of the plurality of transmitter states as a transmitter state according to the frequency band used for the next transmission. The current transmitter state is the mapping relation according to the transmission.

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

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. The number of transmitters corresponding to the frequency band in other mapping relations is greater than or equal to the number of carriers.

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. The number of transmitters corresponding to the frequency band in other mapping relations is greater than or equal to the number of ports.

For example, the current state of the transmitter of the terminal (transmitter state) is: band 1 corresponds to 1 transmitter and band 2 corresponds to 1 transmitter. The frequency band related conditions adopted by the next transmission are as follows: there is transmission on at least 1 carrier in band 2.

In this case, the transmitter of the terminal is switched, and the switched state (other transmitter state) is: the frequency band 1 corresponds to 0 transmitter, and the frequency band 2 corresponds to two transmitters, that is, 1 transmitter supporting frequency band switching originally corresponding to the frequency band 1 is switched to the frequency band 2; otherwise no handover occurs.

For example, the current state of the terminal transmitter is: band 1 corresponds to 0 transmitters and band 2 corresponds to two transmitters. The frequency band related conditions adopted by the next transmission are as follows: there is 1-port (1 port) transmission on the carrier in band 1.

In this case, the terminal transmitter is switched, and the switched state is: the frequency band 1 corresponds to 1 transmitter, and the frequency band 2 corresponds to 1 transmitter, that is, 1 transmitter supporting frequency band switching originally corresponding to the frequency band 2 is switched to the frequency band 1; the rest of the cases do not occur handover.

For example, the current state of the transmitter of the terminal is: band 1 corresponds to two transmitters and band 2 corresponds to 0 transmitters. The frequency band correlation situation adopted by the next transmission is as follows: there is transmission on at least 1 carrier in band 2.

In this case, the transmitter of the terminal is switched, and the switched state is: the frequency band 1 corresponds to 0 transmitter, and the frequency band 2 corresponds to two transmitters, that is, 1 transmitter supporting frequency band switching originally corresponding to the frequency band 1 is switched to the frequency band 2; the rest of the cases do not occur handover.

For example, the current state of the terminal transmitter is: band 1 corresponds to 0 transmitters and band 2 corresponds to two transmitters. The frequency band correlation situation adopted by the next transmission is as follows: there is 1-port transmission on the carrier in band 1.

In this case, the terminal transmitter is switched, and the switched state is: the frequency band 1 corresponds to 2 transmitters, and the frequency band 2 corresponds to 0 transmitter, that is, two transmitters supporting frequency band switching originally corresponding to the frequency band 2 are switched to the frequency band 1; the rest of the cases do not occur handover.

For example, the current state of the transmitter of the terminal is: band 1 corresponds to 1 transmitter and band 2 corresponds to 1 transmitter. The frequency band related conditions adopted by the next transmission are as follows: there is 2-port transmission on at least 1 carrier in band 2.

In this case, the transmitter of the terminal is switched, and the switched state is: the frequency band 1 corresponds to 0 transmitter, and the frequency band 2 corresponds to two transmitters, that is, 1 transmitter supporting frequency band switching originally corresponding to the frequency band 1 is switched to the frequency band 2; otherwise no handover occurs.

For example, the current state of the transmitter of the terminal is: band 1 corresponds to 1 transmitter and band 2 corresponds to 1 transmitter. The frequency band correlation situation adopted by the next transmission is as follows: there is 2-port transmission on the carrier in band 1.

In this case, the transmitter of the terminal is switched, and the switched state is: the frequency band 1 corresponds to 2 transmitters, and the frequency band 0 corresponds to two transmitters, that is, 1 transmitter supporting frequency band switching originally corresponding to the frequency band 2 is switched to the frequency band 2; the rest of the cases do not occur handover.

For example, the frequency band correlation used for the next transmission is: there is 2-port transmission on at least 1 carrier in band 2.

In this case, the terminal transmitter is switched, and the switched state is: frequency band 1 corresponds to 0 transmitter, and frequency band 2 corresponds to 2 transmitters, that is, 1 transmitter supporting frequency band switching originally corresponding to frequency band 1 is switched to frequency band 2; the rest of the cases do not occur handover.

For example, the current state of the transmitter of the terminal is: band 1 corresponds to 2 transmitters and band 2 corresponds to 0 transmitters. The frequency band correlation situation adopted by the next transmission is as follows: there is 1-port transmission on at least 1 carrier in band 2.

In this case, the transmitter of the terminal is switched, and the switched state is: in the state 1, the frequency band 1 corresponds to 1 transmitter, and the frequency band 2 corresponds to 1 transmitter; or state 2, band 1 corresponds to 0 transmitters and band 2 corresponds to 2 transmitters. Otherwise no handover occurs.

State 1 or state 2 may be fixed by the protocol; or the base station indicates the terminal to select the state 1 or the state 2 through signaling; the terminal may decide the state 1 or the state 2 by itself.

For example, the frequency band correlation condition adopted by the next transmission is as follows: there is a 2-port transmission on at least one carrier in band 2.

In this case, the terminal transmitter is switched, and the switched state is: the frequency band 1 corresponds to 0 transmitter, and the frequency band 2 corresponds to 2 transmitters, that is, two transmitters supporting frequency band switching originally corresponding to the frequency band 1 are switched to the frequency band 2; otherwise no handover occurs.

For example, the current state of the transmitter of the terminal is: band 1 corresponds to 0 transmitters and band 2 corresponds to two transmitters. The frequency band correlation situation adopted by the next transmission is as follows: there is 1-port transmission on at least 1 carrier in band 1.

In this case, the transmitter of the terminal is switched, and the switched state is: in the state 1, the frequency band 1 corresponds to 1 transmitter, and the frequency band 2 corresponds to 1 transmitter; or in state 2, the frequency band 1 corresponds to 2 transmitters, and the frequency band 2 corresponds to 0 transmitter. Otherwise no handover occurs.

For example, the frequency band correlation condition adopted by the next transmission is as follows: there is a 2-port transmission on at least one carrier in band 1.

In this case, the terminal transmitter is switched, and the switched state is: frequency band 1 corresponds to two transmitters, and frequency band 2 corresponds to 0 transmitter; the rest of the cases do not occur handover.
