When the terminal device performs uplink transmission, The uplink transmission needs to be sent according to the number of antenna ports in Table 11 and Table 12 above.

In some embodiments, the interval between two adjacent uplink transmissions is the first time interval; the two adjacent uplink transmissions may be understood as the latest two uplink transmissions in the time domain.

Wherein, within the first time interval, the terminal device cannot send information, and/or, the terminal device cannot receive information; or, within the first time interval, the network device does not schedule uplink transmission, and/or, The network device is not configured for uplink transmission.

In some embodiments, the two adjacent uplink transmissions are two uplink transmissions sent on the same carrier, or the two adjacent uplink transmissions are two uplink transmissions sent on different carriers.

In some embodiments, the terminal device determines the first time interval according to at least one of the following information:

Sending link information, switching type information, port number of uplink information to be sent, carrier of uplink information to be sent, port number of previous uplink transmission, and carrier of previous uplink transmission.

In some embodiments, the transmission link information is the number of transmission links corresponding to each carrier. The sending link information is configured by the network device, or the sending link information is obtained by the terminal device through configuration information sent by the network device.

In some embodiments, the handover type information is configured by the network device, or the handover type information is obtained by the terminal device through configuration information sent by the network device. In some embodiments, the network device determines the handover type information according to the handover information, and sends the handover type information to the terminal device.

In some embodiments, a first time interval needs to be reserved between two adjacent uplink transmissions. The two carriers may be two carriers in different frequency bands. It should be understood that the latter uplink transmission is the later uplink transmission among the two adjacent uplink transmissions, and it can also be understood as the uplink information to be sent. The previous uplink transmission It is an earlier uplink transmission among two adjacent uplink transmissions. In the case where the terminal device is not allowed to send uplink transmissions on two carriers at the same time, the two adjacent uplink transmissions satisfy one of the following:

The latter uplink transmission is an uplink transmission of at least one port on one carrier, and the previous uplink transmission is an uplink transmission of at least three ports transmitted on another carrier;

The latter uplink transmission is an uplink transmission of at least three ports transmitted on one carrier, and the previous uplink transmission is an uplink transmission of at least one port transmitted on another carrier;

The latter uplink transmission is an uplink transmission of at least three ports on one carrier, and the previous uplink transmission is an uplink transmission of 1 port or 2 ports on the same carrier, and the carrier does not support uplink transmission of 3 or more ports.

For example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. In addition, the two uplink carriers (ie, carrier 1+carrier 2) will not schedule or configure concurrent uplink transmission, and the mapping relationship between transmission links and antenna ports may be as shown in Table 9 above. As shown in FIG. 3 , a switching interval is required between uplink transmission 1 on carrier 1 and uplink transmission 2 on carrier 2 , for example, the switching interval is the first time interval.

For example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, the two uplink carriers (ie carrier 1+carrier 2) will not schedule or configure concurrent uplink transmission. When a terminal device intends to transmit an uplink transmission of 1 port, 2 ports, or 3 ports or more on one of the carriers, if the previous uplink transmission was an uplink transmission of 3 ports or more ports transmitted on another carrier, the adjacent A switching interval is required between two transmissions of . In other words, the previous uplink transmission occupies all the sending links, and the uplink transmission to be sent can only be transmitted after the sending links are adjusted.

Another example is the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, the two uplink carriers (ie carrier 1+carrier 2) will not schedule or configure concurrent uplink transmission. When a terminal device intends to transmit an uplink transmission of 3 ports or more on one of the carriers, if the previous uplink transmission was a 1-port or 2-port or 3-port or more uplink transmission on the other carrier, twice A toggle interval is required between transfers. In other words, the to-be-sent uplink transmission needs to occupy all the sending links, so the to-be-sent uplink transmission needs to be adjusted before the to-be-sent uplink transmission can be transmitted.

For another example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, the two uplink carriers (ie carrier 1+carrier 2) will not schedule or configure concurrent uplink transmission. When a terminal device wants to transmit an uplink transmission of 3 ports or more on one of the carriers, if the previous uplink transmission was a 1-port or 2-port uplink transmission on the same carrier and the carrier cannot support 3 or more ports For uplink transmission, a switching interval is required between two transmissions. In other words, the same carrier currently does not support 3 sending links (3 ports), so the uplink transmission to be sent can only be transmitted after the sending links are adjusted.

Therefore, in the embodiment of the present application, by defining the scenario of adding the first time interval, within the time of the first time interval, the terminal device needs to adjust the transmission link and cannot send or receive data.

In some embodiments, when the terminal device is allowed to simultaneously send uplink transmissions on two carriers, the two adjacent uplink transmissions satisfy one of the following:

The last uplink transmission is an uplink transmission of port 1 or port 2 on one carrier, and the previous uplink transmission is an uplink transmission of port 1 or port 2 on another carrier, and the carrier corresponding to the previous uplink transmission supports port 3 or more ports for uplink transmission.

It should be noted that the explanations for the two adjacent uplink transmissions, the subsequent uplink transmission, and the previous uplink transmission are the same as the above, and will not be repeated here.

For example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. In addition, two uplink carriers (that is, carrier 1+carrier 2) can schedule or configure concurrent uplink transmission, and the mapping relationship between transmission links and antenna ports can be as shown in Table 10 above. As shown in FIG. 3 , a switching interval is required between uplink transmission 1 on carrier 1 and uplink transmission 2 on carrier 2 , for example, the switching interval is the first time interval.

For example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, two uplink carriers (ie carrier 1+carrier 2) can schedule or configure concurrent uplink transmission. When a terminal device intends to transmit an uplink transmission of 1 port or 2 ports or 3 ports or more on one of the carriers, if the previous uplink transmission was an uplink transmission of 3 ports or more on the other carrier, twice A toggle interval is required between transfers.

Another example is the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, two uplink carriers (ie carrier 1+carrier 2) can schedule or configure concurrent uplink transmission. When a terminal device intends to transmit an uplink transmission of 3 ports or more on one of the carriers, if the previous uplink transmission was a 1-port or 2-port or 3-port or more uplink transmission on the other carrier, twice A toggle interval is required between transfers.

For another example, the transmission link switching scenario: uplink carrier 1 (Band A carrier 1) of frequency band A, and uplink carrier 2 (Band B carrier 2) of frequency band B. Moreover, two uplink carriers (ie carrier 1+carrier 2) can schedule or configure concurrent uplink transmission. When the terminal merges to transmit 1-port or 2-port uplink transmission on one of the carriers, if the previous uplink transmission is 1-port or 2-port uplink transmission on another carrier and the carrier supports 3 or more ports of uplink transmission transmission, a switching interval is required between two transmissions. In other words, the terminal device can support concurrent uplink transmission of two carriers, but the previous transmission can support 3 transmission links, and the carrier where the uplink transmission is to be sent does not have a transmission link, so the transmission link needs to be adjusted before it can Transmit Uplink transmissions to be sent.

Therefore, in the embodiment of this application, by defining the scenario of adding the first time interval, the terminal device needs to adjust the transmission link within the first time interval, and cannot send or receive data, so as to avoid the terminal device and the network device from being affected by the second time interval. There is inconsistent understanding of whether a time interval exists.

In some embodiments, when the terminal device is not allowed to simultaneously send uplink transmissions on carriers located in two frequency bands, the two adjacent uplink transmissions satisfy one of the following:

The latter uplink transmission is an uplink transmission of at least one port on a carrier transmission in one frequency band, and the previous uplink transmission is an uplink transmission of at least three ports on a carrier transmission of another frequency band;

The latter uplink transmission is an uplink transmission of at least three ports transmitted by a carrier in one frequency band, and the previous uplink transmission is an uplink transmission of at least one port transmitted by a carrier of another frequency band;

The last uplink transmission is an uplink transmission of at least three ports on a carrier of a frequency band, and the previous uplink transmission is an uplink transmission of port 1 or port 2 on a carrier of the same frequency band, and the carrier corresponding to the previous uplink transmission does not support Uplink transmission of 3 ports or more;

The last uplink transmission is an uplink transmission of port 1 or port 2 on a carrier transmission in one frequency band, and the previous uplink transmission is an uplink transmission on port 1 or port 2 of a carrier transmission in another frequency band, and the previous uplink transmission corresponds to The carrier supports uplink transmission of 3 or more ports.

For example, uplink carrier 1 (Band A carrier 1) of frequency band A, continuous uplink carrier 2 and uplink carrier 3 (Band B carrier 2+Band B carrier 3) of frequency band B. In addition, the uplink carrier 1 of Band A is not transmitted simultaneously with the uplink carrier (uplink carrier 2 and uplink carrier 3) of Band B, and the mapping relationship between the transmission link and the antenna port can be as shown in Table 11 above. As shown in FIG. 4 , a switching interval is required between uplink transmission 1 on carrier 1 and uplink transmission 2 on carrier 2 , for example, the switching interval is the first time interval. As shown in FIG. 4 , uplink transmission 2 on carrier 2 and uplink transmission 3 on carrier 3 may be performed simultaneously.

For example, uplink carrier 1 (Band A carrier 1) of frequency band A, continuous uplink carrier 2 and uplink carrier 3 (Band B carrier 2+Band B carrier 3) of frequency band B. Moreover, the uplink carrier 1 of Band A is not transmitted simultaneously with the uplink carrier (uplink carrier 2 and uplink carrier 3) of Band B. When a terminal device wants to transmit an uplink transmission of 1 port, 2 ports, or 3 ports or more ports on one of the carriers, if the previous uplink transmission is an uplink transmission of 3 ports or more ports transmitted on another Band carrier, then A toggle interval is required between transfers.

Moreover, the uplink carrier 1 of Band A is not transmitted simultaneously with the uplink carrier (uplink carrier 2 and uplink carrier 3) of Band B. When a terminal device wants to transmit an uplink transmission of 3 ports or more ports on one of the carriers, if the previous uplink transmission is an uplink transmission of 1 port or 2 ports or 3 ports or more ports transmitted on the carrier of another Band, then A toggle interval is required between transfers.

For another example, uplink carrier 1 (Band A carrier 1) of frequency band A, continuous uplink carrier 2 and uplink carrier 3 (Band B carrier 2+Band B carrier 3) of frequency band B. Moreover, the uplink carrier 1 of Band A is not transmitted simultaneously with the uplink carrier (uplink carrier 2 and uplink carrier 3) of Band B. When a terminal device wants to transmit an uplink transmission of 3 ports or more on one of the carriers, if the previous uplink transmission was a 1-port or 2-port uplink transmission transmitted on the carrier of the same Band and the carrier corresponding to the previous uplink transmission cannot To support uplink transmission of 3 or more ports, a switching interval is required between two transmissions.

For another example, uplink carrier 1 (Band A carrier 1) of frequency band A, continuous uplink carrier 2 and uplink carrier 3 (Band B carrier 2+Band B carrier 3) of frequency band B. Moreover, the uplink carrier 1 of Band A is not transmitted simultaneously with the uplink carrier (uplink carrier 2 and uplink carrier 3) of Band B.
