Step 1 in specific implementation can by the following manner one or in a manner of two realize.

Mode one

For a time quantum, if in the time-domain resource of multiple carrier waves including the time quantum, the network equipment is determined Terminal is concurrent in multiple carrier wave on the time quantum.If in the time-domain resource of only one carrier wave including the time quantum, net Network equipment determines that terminal only carries out uplink transmission on the carrier wave on the time quantum.

Mode two

The network equipment is determined only carries out uplink transmission on each time quantum on a carrier wave, i.e., multiple carrier waves are to adopt Uplink transmission is carried out with the mode of TDM.

In mode two, the network equipment (1), mode (2) or mode (3) can guarantee terminal multiple in the following manner Uplink transmission is carried out on carrier wave in a tdm fashion.

Mode (1), the network equipment guarantee to be that the uplink time-domain resource that multiple carrier waves configure is not overlapped.In this case, multiple Carrier wave can be TDD carrier wave.

In DC scene, mode (1) in specific implementation, can be through consultation between master network device and the auxiliary network equipment The time-domain resource configuration for determining each carrier wave of terminal, guarantees that the uplink time-domain resource of different carrier waves is not overlapped.Illustratively, if Master network device and the auxiliary network equipment are the base station NR, then can be assisted by Xn interface between master network device and the auxiliary network equipment Quotient.If master network device and the auxiliary network equipment one are LTE base station, one is the base station NR, then master network device and auxiliary network are set It can be negotiated by X2 interface between standby.

In CA scene, the network equipment can voluntarily determine the time-domain resource configuration of each carrier wave of terminal, guarantee different The uplink time-domain resource of carrier wave is not overlapped.

Illustratively, the network equipment is that the carrier wave 1 of terminal and the time-domain resource of the configuration of carrier wave 2 can be found in Fig. 9.It is exemplary , carrier wave 1 and carrier wave 2 are TDD carrier wave, and the subcarrier spacing of carrier wave 1 is 30kHz, and the subcarrier spacing of carrier wave 2 is 15kHz, The uplink time-domain resource of carrier wave 1 and carrier wave 2 is not overlapped.

Mode (2), the network equipment guarantee that the uplink transmission resource in the uplink time-domain resource for the configuration of multiple carrier waves does not weigh It is folded.

In this case, any one carrier wave in multiple carrier waves can be TDD carrier wave, or FDD carrier wave.

Mode (2) in specific implementation, can be realized by way of configuring TDM pattern.In this case, the network equipment can To configure one or more in multiple carrier waves by the cell TDM pattern configuration (" tdm-PatternConfig ") in RRC signaling The uplink transmission resource in uplink time-domain resource on a carrier wave.

Mode (2) (2-1) or mode (2-2) can specifically be realized in the following manner.

The uplink of the multiple carrier waves of mode (2-1), the network equipment based on the fixation map instruction terminal negotiated with terminal Uplink transmission resource in time-domain resource.

Illustratively, which may refer to table 3.In table 3, U expression can carry out uplink transmission, remaining is indicated not It can be carried out uplink transmission.

Table 3

Based on map is fixed shown in table 3, the network equipment can configure a list item in map for the carrier wave 1 of terminal, When time slot in the time slot of carrier wave 1, identical with the time-gap number in the list item is ascending time slot, being somebody's turn to do for carrier wave 1 is indicated Terminal can carry out uplink transmission on time slot, otherwise indicate that terminal not can be carried out uplink transmission on the time slot.Illustratively, referring to Figure 10, if the network equipment is that carrier wave 1 configures list item 0 in map, then it represents that time slot 2, time slot 3, time slot 4 in 10 time slots, Time slot 7, time slot 8 and time slot 9 can carry out uplink transmission, due to only having time slot 4 and time slot 9 for ascending time slot in carrier wave 1, because This, terminal can only carry out uplink transmission on time slot 4 and time slot 9.For carrier wave 2, terminal can be defaulted upper with carrier wave 1 Uplink transmission is carried out in the nonoverlapping uplink time-domain resource of uplink transmission resource in row time-domain resource.Illustratively, referring to figure 10, if on carrier 1, terminal can only carry out uplink transmission on time slot 4 and time slot 9.So, on carrier 2, terminal can be with In time slot 0, uplink transmission is carried out on time slot 1 and time slot 3.

Whether mode (2-2), the network equipment directly pass through allows on each time slot of each carrier wave of RRC signaling flexible configuration Carry out uplink transmission.

Illustratively, referring to Figure 10, the network equipment is that the information that carrier wave 1 configures may refer to table 4, and the network equipment is carrier wave The information of 2 configurations may refer to table 5.1 expression ascending time slot can carry out uplink transmission, and 0 expression ascending time slot not can be carried out Row is sent.In this case, on carrier 1, terminal can only carry out uplink transmission on time slot 4 and time slot 9, on carrier 2, eventually End can carry out uplink transmission on time slot 0, time slot 1 and time slot 3.

Table 4

Time-gap number	0	1	2	3	4	5	6	7	8	9
											Uplink sends instruction	0	0	0	0	1	0	0	0	0	1

Table 5

Time-gap number	0	1	2	3	4
						Uplink sends instruction	1	1	0	1	0

In DC scene, mode (2) in specific implementation, can be through consultation between master network device and the auxiliary network equipment Determine which uplink time-domain resource is able to carry out uplink transmission in the uplink time-domain resource of each carrier wave of terminal, to guarantee not It is not overlapped with the uplink time-domain resource for being able to carry out uplink transmission in the uplink time-domain resource of carrier wave.Illustratively, if major network Network equipment and the auxiliary network equipment are the base station NR, then can pass through Xn interface negotiation between master network device and the auxiliary network equipment. If master network device and the auxiliary network equipment one are LTE base station, one be the base station NR, then master network device and the auxiliary network equipment it Between can be negotiated by X2 interface.

In CA scene, the network equipment can voluntarily determine which uplink in the uplink time-domain resource of each carrier wave of terminal Time-domain resource is able to carry out uplink transmission, to guarantee to be able to carry out what uplink was sent in the uplink time-domain resource of different carrier waves Uplink time-domain resource is not overlapped.

For the uplink time-domain resource of the overlapping of different carrier waves, the network equipment can determine the uplink throughput of different carrier waves And/or occlusion rate, the partly overlapping uplink time-domain resource uplink throughput it is higher and/or occlusion the lower carrier wave of rate On be able to carry out uplink transmission.

Mode (3) is dispatched by the network equipment and realizes that terminal carries out uplink transmission in a tdm fashion on N number of carrier wave.

The network equipment can guarantee the time-domain resource that terminal is used when carrying out uplink transmission on different carrier waves by scheduling It is not overlapped, that is, ensures between different carrier waves to be not in complications.Illustratively, referring to Fig. 5, terminal can be carried in 2.6GHz The upstream data of 3 dispatch terminal of time slot of wave is carried in the upstream data of 9 dispatch terminal of time slot of 3.5GHz carrier wave in 2.6GHz The preceding half-slot (i.e. the time slot 4 of 3.5GHz carrier wave) of the time slot 2 of wave, terminal are dispatched on 2.6GHz carrier wave or 3.5GHz carrier wave The upstream data of terminal.

Mode two can to avoid due to multiple carrier waves concurrently caused by carrier wave uplink transmission power decline the problem of.

Step 2, the network equipment are according in the accounting of the uplink transmission resource in N number of time quantum and N number of time quantum Each time quantum on sending method (single-shot or concurrent) determine the actual maximum hair of each carrier wave on each time quantum Penetrate power.

In view of SAR index demand, average uplink transmission power of the terminal in N number of time quantum is no more than 23dBm.It examines The maximum transmission power for considering terminal, in a time quantum, (i.e. over a number of carriers upper of the uplink transmission power of terminal The sum of row transmission power) it is no more than the maximum transmission power of terminal.It, can be as far as possible in the case where meeting the two conditions Promote the uplink transmission power of terminal.On each time quantum, the network equipment can pass through the upper of closed-loop power control controlling terminal Row transmission power is no more than actual maximum transmission power.

For example, in the case that the accounting of the uplink transmission resource in N number of time quantum is less than 1, it can be to part-time list Uplink transmission power in member is promoted, for example, the carrier wave for being 26dBm for the maximum transmission power supported, it can be by portion The uplink transmission power divided on time quantum is promoted from 23dBm to 26dBm.

Illustratively, referring to Figure 11,3.5GHz carrier wave is TDD carrier wave, and the maximum transmission power of support is 26dBm, 2.1GHz carrier wave is FDD carrier wave, and the maximum transmission power of support is 23dBm, then the maximum transmission power of terminal is 26dBm.By It is sent in the time slot 5 of 3.5GHz carrier wave without uplink in terminal, then the uplink transmission power of time slot 5 can be used for enhancing time slot 4 uplink transmission power.At this point, the network equipment can determine the time slot 0 in 3.5GHz carrier wave, time slot 1, time slot 2, time slot 3, when The actual maximum transmission power of 2.1GHz carrier wave is 23dBm in gap 6, time slot 7, on the time slot 8 and time slot 9 of 3.5GHz carrier wave The actual maximum transmission power of 3.5GHz carrier wave is 23dBm, the actual maximum of 3.5GHz carrier wave on the time slot 4 of 3.5GHz carrier wave Transmission power is 26dBm.

Step 3, the network equipment send the second configuration information to terminal.

Before step 3, the network equipment can determine that each carrier wave that uplink transmission is carried out on first time unit uses Uplink transmission power, mode 1 and implementation 2 can specifically be achieved by the following way and realize.
