- the terminal device can perform time-division transmission between the two configured carriers, and the terminal device has a total of two radio frequency chains that can transmit simultaneously.

- a transmit channel is a physical concept, and may also be called a radio frequency (radio frequency, RF).
- the transmit channel is simply referred to as a radio frequency chain.
- the radio frequency chain in this application can also be replaced with Tx, antenna, radio frequency, transmit channel, transmit port, receive channel or any combination thereof.
- the number of radio frequency chains of a terminal device on a carrier is X, which means that the terminal device supports uplink transmission with the number of antenna ports on this carrier less than or equal to X, and does not support uplink transmission with the number of antenna ports greater than X.
- the operating state of the terminal device is the uplink transmission with the number of antenna ports supported by this carrier less than or equal to X, and does not support the uplink transmission with the number of antenna ports greater than X, where X is a positive integer.
- the radio frequency chain may work in the following manner, but is not limited to the following manner: the radio frequency chain may receive the baseband signal from the baseband chip, and perform radio frequency processing (such as up-conversion, amplification and filtering) on the baseband signal to obtain the radio frequency signal , and finally radiate the radio frequency signal into space through the antenna.
- the radio frequency chain may include an antenna switch, an antenna tuner, a low noise amplifier (LNA), a power amplifier (PA), a mixer (mixer), and a local oscillator (LO) , filter (filter) and other electronic devices, these electronic devices can be integrated into one or more chips as required. Antennas can also sometimes be considered part of the RF chain.
- Antenna port is a logical concept. When actually sending a signal, the terminal device will map the antenna port to the corresponding radio frequency chain. When scheduling the terminal device to transmit data, the network device may explicitly indicate the port number of the antenna port used by the terminal device to transmit data.
- the antenna port may be referred to as a port for short.
- R16 proposes a new uplink mode, that is, if the terminal equipment supports two uplink carriers, the terminal equipment can perform Tx switching on these two carriers, thereby improving the utilization rate of the radio frequency chain.
- the protocol defines the sending behavior of the terminal device on the two uplink carriers through Table 1.
- Tx switching may be replaced by uplink Tx switching, dynamic uplink Tx switching, uplink switching, or dynamic Tx switching, which is not limited in this application.

- case2 indicates that the terminal equipment has no radio frequency chain on carrier X, and has 2 radio frequency chains on carrier Y.
- the terminal device supports a maximum of 1 Tx on carrier X and a maximum of 2 Tx on carrier Y.
- the terminal device can switch between these two cases, that is, one Tx can be switched between two carriers, and switching between these two cases requires switching time.
- This switching time can be called uplink switching time (uplink switching gap).
- the terminal equipment does not wish to transmit on either of the two carriers within the uplink switching gap.
- the protocol does not directly instruct the terminal equipment to perform Tx switching on the carrier, but indirectly instructs the terminal equipment to perform Tx switching through the number of uplink transmission ports of the terminal equipment on the carrier, and then determines whether the radio frequency chain switching is required for this uplink transmission. That is, whether there is a switching time.
- Table 2 shows the mapping relationship between the radio frequency chain and the uplink transmission port.
- Table 2 shows the mapping relationship between the Tx and the uplink transmission port of the terminal equipment supporting the uplink CA in the switched mode (switchedUL).

- Table 3 shows the mapping relationship between the Tx and the uplink transmission port of the terminal equipment supporting the uplink CA in the concurrent mode (dualUL).
- the terminal device can send 1port uplink transmission on carrier X while there is no uplink transmission on carrier Y (1P+0P), and send 1port on carrier X
- the uplink transmission of 1 port is sent on the carrier Y at the same time (1P+1P), and the uplink transmission of 1 port is sent on the carrier Y while there is no uplink transmission on the carrier X (0P+1P).
- the operating state of the terminal equipment is that the carrier X supports 1port uplink transmission, or the operating state of the terminal equipment is that the carrier Y supports 1port uplink transmission, or the operating state of the terminal equipment is that the carrier X supports 1port uplink transmission and at the same time Carrier Y supports 1port uplink transmission, or the operating status of the terminal equipment is that carrier X does not support 2port uplink transmission and carrier Y does not support 2port uplink transmission, or the operating status of the terminal equipment is that carrier X does not support 2port uplink transmission , or the operating state of the terminal device is that carrier Y does not support 2port uplink transmission.

- the operating state of the terminal equipment is to support 2port or 1port uplink transmission on carrier Y and not support uplink transmission on carrier X.
- both case1 and case2 are in the state of 0P+1P. If the terminal equipment is about to perform 1port transmission on carrier Y and there is no uplink transmission on carrier X, the Tx state of the terminal equipment is the Tx state of the last uplink transmission. That is, the Tx state of the terminal device does not change, that is, the terminal device does not need switching time.
- the protocol determines whether switching time is required according to the number of upstream transmission ports to be sent by the terminal device on the two carriers, the number of ports in the last upstream transmission, and the number of supported upstream transmission ports or the operating status of the terminal device.
- 2port is to be sent on a carrier for transmission
- the previous transmission is 1port transmission on this carrier
- the operating state of the terminal device is that 2port transmission is not supported on this carrier, that is, switching from 0P+1P of case1 To 0P+2P of case2, the terminal equipment needs to perform Tx switching at this time, and does not want to transmit on either of the two carriers in the uplink switching gap.
- 1port transmission is about to be sent on one carrier
- the previous transmission is 1port transmission on another carrier
