The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein.
In the embodiment of the present invention, the terminal may also be referred to as a terminal Device or a User Equipment (UE), and the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device. It should be noted that, in the embodiment of the present invention, the specific type of the terminal is not limited.
Optionally, the embodiment of the invention is applicable to NN-DC scenes.
Referring to fig. 1, fig. 1 is a flowchart of an uplink transmission power allocation method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 1, the method includes the following steps:
step 101: and under the condition that the sum of the first power and the second power is greater than the third power, performing power distribution on the uplink transmission of the terminal in the MCG and the SCG within a preset time window.
Wherein the first power is a transmission power (P _ MCG) of the terminal at the MCG, namely a pre-transmission power at the MCG before power distribution. The second power is a transmission power (P _ SCG) of the terminal at SCG, i.e., a pre-transmission power at SCG before power allocation. The third power is the maximum total transmission power of the configured terminal, and the maximum total transmission power is the sum of the transmission powers of the terminal in the MCG and the SCG (P _ MCG _ SCG _ total).
Optionally, the communication systems of the MCG and the SCG are the same. For example, the MCG and the SCG are CG in NN-DC scenario.
Optionally, the MCG and the SCG are located in the same frequency range. For example, the MCG is located in Frequency Range (FR) 1, and the SCG is located in FR1; alternatively, the MCG is located in FR2 and the SCG is located in FR2.
In one embodiment, the MCG and the SCG have the same communication system, and the MCG and the SCG are located in the same frequency range.
It can be understood that the terminal in this embodiment has a dynamic power sharing capability. The sum of the maximum transmission power (P _ MCG _ configuration) of the terminal configured by the network device in the MCG and the maximum transmission power (P _ SCG _ configuration) of the terminal configured by the network device in the SCG can be larger than or equal to the maximum transmission total power (P _ MCG _ SCG _ total) of the terminal configured by the network device in the MCG and the SCG, namely P _ MCG _ configuration + P _ SCG _ configuration ≧ P _ MCG _ SCG _ total.
According to the uplink transmission power distribution method provided by the embodiment of the invention, the terminal can distribute the power of the uplink transmission between the MCG and the SCG within the preset time window, so that the reasonable power distribution between the MCG and the SCG is realized, the uplink coverage performance is enhanced, the discontinuous uplink transmission phase is avoided, and the reliability of the uplink transmission is ensured.
In an embodiment of the present invention, the ending time of the preset time window may be: the start time (for example, t 0) of the uplink transmission of the terminal is subtracted by the first offset (t _ offset), i.e., t0 to t _ offset.
Optionally, the starting time of the uplink transmission of the terminal may be any one of the following:
the earliest of the first start time and the second start time;
a first start time.
And the first starting time is the starting time of the uplink transmission of the terminal in the MCG. For example, the first start time is a start time of uplink transmission of the terminal in all cells of the MCG. And the second starting time is the starting time of uplink transmission of the terminal in the SCG. For example, the second start time is the start time of uplink transmission of the terminal in all cells of the SCG.
Optionally, the first offset may be any of the following:
multiplexing processing time delay of Uplink Control Information (UCI) of the terminal; wherein the length of the processing time delay is equal to the multiplexing processing time of the UCI;
a value of a network device configuration; for example, the value may be configured by the network device through radio resource control signaling.
Optionally, the UCI multiplexing processing delay of the terminal may be any one of the following:
1) UCI multiplexing processing time delay of terminal in first CG
The first CG is the earliest uplink transmission configured in the MCG and the SCG. For example, the UCI multiplexing processing delay under 1) may be the UCI multiplexing processing delay of the cell with the earliest uplink transmission configured by the terminal in the cells of the MCG and the SCG (for example, all the cells of the MCG and the SCG).
2) UCI multiplexing processing time delay of terminal in MCG
For example, the UCI multiplexing processing delay under 2) may be the UCI multiplexing processing delay of the terminal in the cell of the MCG.
3) Maximum UCI multiplexing processing time delay of terminal in MCG and SCG
For example, the UCI multiplexing processing delay under 3) is the maximum UCI multiplexing processing delay of the terminal in the MCG cell and the SCG cell (for example, all the MCG and SCG cells).
4) UCI multiplexing processing time delay of terminal in second CG
Wherein, the second CG is the largest subcarrier interval in the MCG and the SCG. For example, the UCI multiplexing processing delay under 5) may be the UCI multiplexing processing delay of a cell with the largest subcarrier spacing in the cell of the MCG and the cell of the SCG (for example, all the cells of the MCG and the SCG) of the terminal.
5) UCI multiplexing processing time delay of terminal in third CG
Wherein, the third CG is the smallest subcarrier spacing in MCG and SCG. For example, the UCI multiplexing processing delay under 4) may be the UCI multiplexing processing delay of a cell with the smallest subcarrier spacing in the cell of the MCG and the cell of the SCG (e.g., all the cells of the MCG and the SCG) of the terminal.
Optionally, the starting time of the preset time window may be: and the receiving moment of the first uplink grant. Wherein the first uplink grant is: the earliest reception time among the at least one uplink grant corresponding to an uplink transmission not actually started in the MCG and SCG. I.e. the uplink transmission of the at least one uplink grant indication does not start transmission.
Therefore, by means of the starting time and the ending time, when the terminal performs power allocation in a preset time window, the corresponding uplink transmission does not start transmission and has sufficient information preparation time, so that reasonable power allocation between the MCG and the SCG is realized.
In this embodiment of the present invention, the power allocation for the uplink transmission of the terminal in the MCG and the SCG in step 101 may be:
and performing power distribution on the uplink transmission of the terminal in the MCG and the SCG according to the first priority.
Wherein the first priority is determined according to at least one of:
power allocation priorities of MCG and SCG;
the transmission priority of the uplink channel; wherein, the transmission priority of the uplink channel can be understood as power distribution priority; the transmission priority of the different uplink channels may be agreed by the protocol.
In one embodiment, the first priority may be determined separately according to the power allocation priorities of the MCG and the SCG. Optionally, the first priority is that the power allocation priority of the MCG is higher than the power allocation priority of the SCG, and performing power allocation on uplink transmission of the terminal in the MCG and the SCG according to the first priority is as follows: the terminal preferentially performs power distribution on the MCG uplink transmission and then performs power distribution on the SCG uplink transmission.
In another embodiment, the first priority may be determined separately according to a transmission priority of the uplink channel. Optionally, the transmission priority of the first uplink channel is higher than the transmission priority of the second uplink channel, and performing power allocation on uplink transmission of the terminal in the MCG and the SCG according to the first priority includes: the UE preferentially performs power distribution on the uplink transmission of the first uplink channel and then performs power distribution on the uplink transmission of the second uplink channel. If the transmission priority of a first uplink channel in the MCG is higher than the transmission priority of a second uplink channel in the SCG, the first priority is that the power distribution priority of the MCG is higher than that of the SCG; or, if the transmission priority of the first uplink channel in the SCG is higher than the transmission priority of the second uplink channel in the MCG, the first priority is that the power allocation priority of the SCG is higher than the power allocation priority of the MCG. For example, the transmission priority of a Random Access Channel (RACH) is higher than that of a Physical Uplink Control Channel (PUCCH), and if the transmission priority of the RACH in the MCG is higher than that of the PUSCH in the SCG, the first priority is that the power allocation priority of the MCG is higher than that of the SCG; alternatively, if the transmission priority of the RACH in the SCG is higher than the transmission priority of the PUSCH in the MCG, the first priority is that the power allocation priority of the SCG is higher than the power allocation priority of the MCG.
In another embodiment, the first priority may be determined according to a power allocation priority of the MCG and the SCG, and a transmission priority of an uplink channel in the MCG and the SCG. Wherein, under the condition that the transmission priority of the uplink channel in the MCG and the SCG is the same, the power allocation priority of the MCG is higher than that of the SCG.
Alternatively, in jointly determining the first priority, the transmission priority of the uplink channel in the MCG and the SCG may be prioritized over the power allocation priority of the MCG and the SCG. For example, the transmission priority of the first uplink channel is higher than the transmission priority of the second uplink channel, and the power allocation of the terminal on the uplink transmissions of the MCG and the SCG according to the first priority is as follows: the terminal preferentially performs power distribution on the uplink transmission of the first uplink channel and then performs power distribution on the uplink transmission of the second uplink channel. Assuming that the transmission priority of RACH is higher than that of PUCCH and the power allocation priority of MCG is higher than that of SCG, according to the protocol, then: if the MCG transmits the PUCCH and the SCG transmits the RACH, the first priority determined at this time is: the power distribution priority of the SCG is higher than that of the MCG, namely, the SCG is determined according to the transmission priority of the uplink channels in the MCG and the SCG. Only if the transmission priority of the uplink channel is the same, the power allocation priority of the MCG and the SCG is considered. For example, if the PUCCH is transmitted on both the MCG and the SCG, that is, the channel transmission priorities are the same, the first priority determined at this time is: the power allocation priority of the MCG is higher than the power allocation priority of the SCG.
Further, the power allocation method of the present embodiment may further include:
and when the sum of the first power and the second power is greater than the third power, performing power distribution on the uplink transmission of the terminal in the MCG and the SCG according to a second priority outside a preset time window.
Wherein the second priority comprises: the power allocation priority of the fourth CG is higher than that of the fifth CG. Optionally, the fourth CG is one of the MCG and the SCG that has the earlier uplink grant receiving time, and the fifth CG is one of the MCG and the SCG that has the later uplink grant receiving time. Or, the fourth CG is one of the MCG and the SCG that has a short UCI multiplexing processing time delay, and the fifth CG is one of the MCG and the SCG that has a long UCI multiplexing processing time delay.
The present invention is described in detail below with reference to examples one to four.
Example one
In this example, please refer to fig. 2, it is assumed that the receiving time of the uplink grant (UL grant) corresponding to the uplink transmission that is not actually started in the MCG is t1, the receiving time of the UL grant corresponding to the uplink transmission that is not actually started in the SCG is t2, and t1< t2; the offset configured by the network equipment is t _ offset; the starting time of the uplink transmission of the UE1 in the MCG is t3, the starting time of the uplink transmission of the UE1 in the SCG is t4, and t3 is less than t4; according to the transmission priority of different channels appointed by the protocol, the transmission priority of the uplink channel in the MCG is the same as that of the uplink channel in the SCG; then:
the starting time of the preset time window is as follows: t1 (i.e. the earliest reception time in the uplink grant corresponding to the uplink transmission not actually started in the MCG and SCG).
The end time of the preset time window is: t3-t _ offset; t3 is the earliest starting time of uplink transmission of UE1 in MCG and SCG.
In a preset time window, the UE1 preferentially performs power distribution on the uplink transmission of the MCG and then performs power distribution on the uplink transmission of the SCG according to the power distribution priority of the MCG which is higher than the power distribution priority of the SCG. Therefore, as the UE1 performs power distribution on the MCG and SCG uplink transmission in the preset time window, reasonable power distribution between the MCG and the SCG can be realized, and the MCG uplink transmission does not need to be readjusted when the SCG starts uplink transmission at t4, namely, the SCG starts uplink transmission, thereby avoiding discontinuous uplink transmission phase and ensuring the reliability of uplink transmission.
Outside the preset time window, the UE1 performs power allocation on the uplink transmissions of the MCG and the SCG according to the sequence of the reception time of the UL grant.
Example two
In this second example, please refer to fig. 3, it is assumed that the receiving time of the UL grant corresponding to the uplink transmission that is not actually started in the MCG is t2, the receiving time of the UL grant corresponding to the uplink transmission that is not actually started in the SCG is t1, and t1< t2; the offset configured by the network equipment is t _ offset; the starting time of the uplink transmission of the UE2 in the MCG is t4, the starting time of the uplink transmission of the UE2 in the SCG is t3, and t3 is less than t4; according to the transmission priority of different channels appointed by the protocol, the transmission priority of the uplink channel in the MCG is the same as that of the uplink channel in the SCG; then:
the starting time of the preset time window is as follows: t1 (i.e. the earliest reception time in the uplink grant corresponding to the uplink transmission not actually started in the MCG and SCG).
The end time of the preset time window is: t3-t _ offset; t3 is the earliest starting time of uplink transmission of UE2 in MCG and SCG.
And in a preset time window, the UE2 preferentially performs power distribution on the uplink transmission of the MCG and then performs power distribution on the uplink transmission of the SCG according to the power distribution priority of the MCG which is higher than the power distribution priority of the SCG. Therefore, the UE2 distributes the power of the uplink transmission of the MCG and the SCG in the preset time window, so that the reasonable power distribution between the MCG and the SCG can be realized, and the uplink transmission of the SCG does not need to be readjusted when the MCG starts the uplink transmission at t4, so that the discontinuous uplink transmission phase is avoided, and the reliability of the uplink transmission is ensured.
And outside the preset time window, the UE2 carries out power distribution on the uplink transmission of the MCG and the SCG according to the receiving time sequence of the UL grant.
Example three
In the third example, please refer to fig. 4, it is assumed that the receiving time of the UL grant corresponding to the uplink transmission that is not actually started in the MCG is t2, the receiving time of the UL grant corresponding to the uplink transmission that is not actually started in the SCG is t1, and t1< t2; the offset configured by the network equipment is t _ offset; the starting time of the uplink transmission of the UE3 in the MCG is t4, the starting time of the uplink transmission of the UE2 in the SCG is t3, and t3 is less than t4; then:
the starting time of the preset time window is as follows: t1 (i.e. the earliest reception time in the uplink grant corresponding to the uplink transmission not actually started in the MCG and SCG).
The end time of the preset time window is as follows: t4-t _ offset; t4 is the start time of uplink transmission of UE3 in the MCG.
And in a preset time window, the UE3 preferentially performs power distribution on the uplink transmission of the MCG and then performs power distribution on the uplink transmission of the SCG according to the power distribution priority of the MCG which is higher than the power distribution priority of the SCG. Therefore, the UE3 distributes the power of the uplink transmission of the MCG and the SCG in the preset time window, so that the reasonable power distribution between the MCG and the SCG can be realized, and the uplink transmission of the SCG does not need to be readjusted when the MCG starts the uplink transmission at t4, so that the discontinuous uplink transmission phase is avoided, and the reliability of the uplink transmission is ensured.
Outside the preset time window, the UE3 performs power allocation on the uplink transmissions of the MCG and the SCG according to the sequence of the reception time of the UL grant.
Example four
In this fourth example, please refer to fig. 5, suppose that the receiving time of the UL grant corresponding to the uplink transmission not actually started in the MCG is t1, the receiving time of the UL grant corresponding to the uplink transmission not actually started in the SCG is t2, and t1< t2; the starting time of the uplink transmission of the UE4 in the MCG is t3, and the UCI multiplexing processing time delay is t _ offset1; the starting time of uplink transmission of the UE4 in the SCG is t3, the UCI multiplexing processing delay is t _ offset2, and t _ offset1> t _ offset2; then:
the starting time of the preset time window is as follows: t1 (i.e. the earliest reception time in the uplink grant corresponding to the uplink transmission not actually started in the MCG and SCG).
The end time of the preset time window is as follows: t3-t _ offset1; the t _ offset1 is the maximum UCI multiplexing processing delay of the UE4 at the MCG and SCG.
And in the preset time window, the UE4 preferentially performs power distribution on the uplink transmission of the MCG and then performs power distribution on the uplink transmission of the SCG according to the power distribution priority of the MCG which is higher than the power distribution priority of the SCG. In this way, since the UE4 performs power allocation on the MCG and SCG uplink transmissions within the preset time window, it is possible to achieve reasonable power allocation between the MCG and SCG, and enhance uplink coverage performance.
Outside the preset time window, the UE4 performs power allocation on the uplink transmissions of the MCG and the SCG according to the sequence of the reception time of the UL grant.
