technical field

The present invention relates to the technical field of communications, and in particular to a method and device for allocating transmission power of an uplink channel, a terminal and a storage medium.

Background technique

During the concurrent uplink process of the New Radio (NR) and Long Term Evolution (LTE) in the Non-Standalone operation mode (NSA) of the mobile communication terminal, both NR and LTE have their own transmission Power and timing, if the two overlap in time (Overlap), and the sum of the transmission power of the two in the Overlap part exceeds the limit range, it is necessary to process the transmission of the NR in the Overlap part.

In general, the routine processing is: According to the relevant description in 3GPP protocol 38.213/38.101-3, the maximum value of the sum of NR and LTE transmission power in different scenarios of NSA, in (E-UTRA NR dual connectivity with MCG using E- UTRA and SCG using NR, EN-DC) is

And under (E-UTRA NR dual connectivity with MCG using NR and SCG using E-UTRA, NE-DC) is

Once the sum of the transmission power of the Overlap part of NR and LTE exceeds the maximum value configured above, the transmission power of NR will be directly reduced; and under EN-DC, if the reduction range of NR transmission power exceeds the maximum reduction range setting of NR uplink channel power Fixed value (XSCALE), you can directly give up the sending of NR. Since the uplink transmission channel of NR may be more important, if the transmission power is directly reduced or even cut off, the connection performance of the NR link under NSA will be reduced, and in severe cases, NR may not even be able to stay on the network or be disconnected from the network.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In the prior art, when an NR terminal performs uplink transmission of NR and LTE under NSA, it first judges whether there is an overlap in the uplink channel transmission of NR and LTE in time, and then judges the sum of the uplink transmission power of NR and LTE in the Overlap part If the limit is exceeded, adjust the uplink channel transmit power of the Overlap part of NR to ensure that the sum of NR and LTE uplink transmit power does not exceed the range. For this reason, the conventional processing is: when performing uplink transmission of NR and LTE under NSA, once it is judged that the uplink channel transmission of NR and LTE has an Overlap in time, and the sum of the uplink transmission power of NR and LTE in the Overlap part If the limit is exceeded, regardless of EN-DC or NE-DC, the uplink transmission power of the Overlap part NR will be unconditionally reduced, and even the transmission of NR will be abandoned when the power is reduced a lot.

Figure 1 is a flow chart of protocol processing for uplink transmission power allocation between NR and LTE under NSA in the prior art. During the uplink transmit power allocation process between NR and LTE, the following steps need to be performed:

Step 101: In the NSA uplink concurrent phase, confirm whether there is an overlap in time between the uplink channel transmission of NR and LTE. If there is no overlap in time between the uplink channel transmission of NR and LTE, then perform step 102. If there is an overlap in time, step 103 is performed.

Step 102: The NR internally allocates the transmission power.

Step 103: Determine the current NSA type, if the NSA type is NE-DC, execute step 104, if the NSA type is EN-DC, execute step 105.

Step 104: Adjust the transmission power of the sampling points of the Overlap part of the NR and LTE uplink channel according to the protocol to

Step 105: Determine whether to drop the channel sent on the NR, once it is judged that the sum of the uplink transmission power of the Overlap part NR and LTE exceeds the limit range (that is, determine

), then execute step 106, if it is determined that the sum of the uplink transmission power of the Overlap part NR and LTE does not exceed the limit range (that is, determine

), then execute step 107.

Step 106: Drop the channel sent on the NR.

Step 107: adjust the transmission power of the sampling point of the Overlap part of the NR and LTE uplink channel according to the agreement to

After that, step 102 is performed.

In the above-mentioned NR uplink transmission power control method in the prior art, if the transmission on the NR is a more important channel (such as PRACH), the power is reduced or even the transmission is abandoned, which has a great impact on the connection performance of the NR uplink.

In order to overcome the above technical problems, an embodiment of the present application provides a method for allocating uplink channel transmission power. The method for allocating uplink channel transmission power can be applied to concurrent application scenarios of NR and LTE under NSA, that is, it can include NE-DC scenarios and EN -DC scene.

The technical solutions provided by the embodiments of the present application may be implemented by user equipment in the above scenario, such as NR terminals. Furthermore, the connection performance of the NR uplink can be enhanced by optimizing the transmission power of the NR uplink and LTE Overlap without affecting the RRC Connect state LTE uplink connection performance. In order to ensure the connection performance of the LTE link, the problem of blindly reducing the connection performance of the NR link or even canceling the transmission of the NR uplink channel is avoided.

Figure 2 is a flow chart of an uplink channel transmission power allocation method provided by an embodiment of the present application. As shown in Figure 2, the power allocation method includes the following steps:

Step 201: In the NSA uplink concurrent phase, confirm whether there is an overlap in time between the NR and LTE uplink channels to be sent, if there is no overlap, perform step 202, and if there is overlap, perform step 203.

Step 202: Allocation of transmit power for NR and LTE respectively.

Step 203: Determine whether the drop in transmit power of the first NR uplink channel exceeds a first threshold within the overlapping time, if not, execute step 202, if not, execute step 204.

Step 204: Reduce the transmission power of the first set of NR uplink sampling points in the Overlap part by a first power value to obtain the transmission power of the NR overlapping part, and decrease the second power based on the transmission power of the second set of NR uplink sampling points within the overlapping time The NR non-overlapping portion transmit power is determined as a result of the value reduction, and the NR overlapping portion transmit power and the NR non-overlapping portion transmit power are concatenated to obtain the NR uplink target transmit power.

In the specific implementation of step 201, at the stage of determining whether NR and LTE have an overlap, the uplink information within the time period of the upcoming uplink channel can be sent in a chronological order before an NR/LTE uplink channel is about to be sent. Channels (namely, other LTE/NR uplink channels that are known and not yet sent) are judged to determine whether there is an overlap in time.

Wherein, determining that NR and LTE uplink channel transmissions overlap in time may include:

Determine the uplink channel to be sent in chronological order, and if the uplink channel to be sent is an NR uplink channel, determine whether there is a sending time period with the NR uplink channel to be sent in other uplink channels that are not sent If there is an overlapping LTE uplink channel, it is determined that the NR to be sent overlaps in time with the LTE uplink channel; or

Determine the uplink channel to be sent in chronological order, if the uplink channel to be sent is an LTE uplink channel, determine whether there is a sending time period with the LTE uplink channel to be sent in other uplink channels not sent If there is an overlapping NR uplink channel, it is determined that the NR to be sent and the LTE uplink channel overlap in time.

According to the determination result, if the NR and LTE uplink channel transmissions do not overlap in time, perform step 202, and if the NR and LTE uplink channel transmissions overlap in time, perform step 203.

Figure 2a is a schematic diagram of the Time Overlap of NR and LTE uplink channels provided by an embodiment of the present application, as shown in Figure 2a, the first NR uplink channel is about to be sent in the time period t ₀ ~ t ₅ , at t ₀ ~ t In the time period of ₅ , there is an overlap between the unsent LTE uplink channel and the first NR uplink channel to be sent in time, and the corresponding Overlap part is t ₂ ~ t ₃ time period and t ₄ ~ t ₅ time periods.

In other implementation manners, it may also be determined whether the first NR uplink channel to be sent and the LTE uplink channel being sent overlap in time, or whether the LTE uplink channel to be sent and the first NR uplink channel being sent overlap in time. Whether there is an Overlap on it. As shown in Figure 2a, there is an overlap in time between the first NR uplink channel to be sent and the LTE uplink channel being sent, and the corresponding overlap part is the time period t ₀ -t ₁ .

In the specific implementation of step 202, according to the determination result of step 201, after it is determined that the uplink channel transmission of NR and LTE does not overlap in time, NR and LTE can be allocated to transmit power respectively. According to the determination result of step 203, the sum of the transmission power of all uplink channels in the Overlap part of the time of determining the uplink channels of NR and LTE does not exceed the maximum total transmission power of NSA

Then NR and LTE can be made to allocate their respective transmit powers. Or the sum of the transmit power of all uplink channels exceeds the maximum total transmit power of NSA in the Overlap part of the time when the uplink channel transmission of NR and LTE is determined

And reduce the transmission power of the NR uplink channel in the Overlap part, and when the reduction is less than the first threshold (X _SCALE ), the transmission power of the LTE uplink channel remains unchanged, that is, the power allocation is performed according to the original calculation value of the LTE uplink power, and the Overlap part The transmit power of the NR uplink channel is allocated with the reduced transmit power.

Before performing step 203, the following steps may also be performed:

Determine whether the sum of the transmit power of all uplink channels exceeds the maximum total transmit power of the NSA during the overlapping time:

Among them, if the sum of the transmission power of all uplink channels within the overlapping time does not exceed the maximum total transmission power of NSA, the uplink channels of NR and LTE to be transmitted will be allocated according to their original calculation values of uplink power;

If the sum of the transmission power of all uplink channels exceeds the maximum total transmission power of NSA within the overlapping time, reduce the transmission power of the NR uplink channel, and determine whether the decrease in the transmission power of the NR uplink channel exceeds the first threshold, if the decrease If the amplitude does not exceed the first threshold, the NR uplink channel performs power allocation according to the reduced power value.

Wherein, determining whether the sum of the transmit powers of all uplink channels within the overlapping time exceeds the maximum total transmit power of the NSA includes: taking the sampling points in the time domain of the uplink channels to be sent as the granularity, and sampling one by one in chronological order Point to determine whether the sum of the transmit power of all uplink channels exceeds the maximum total transmit power of the NSA within the overlapping time. Specifically, it can be judged according to the sampling point set S2 and the sampling point set S3 shown in FIG. 2a whether the sum of the transmission power of the NR uplink channel to be transmitted and the untransmitted LTE uplink channel exceeds the maximum total transmission power of the NSA.

In the specific implementation of step 203, it is judged whether the sum of the transmission power of all uplink channels in the overlapping time (Overlap part) exceeds the maximum total transmission power of NSA

If the maximum total transmission power of NSA is not exceeded

Then execute step 202, if the maximum total transmission power of NSA is exceeded

Then step 204 is executed.

In the specific implementation of step 204, this step 204 may include the following sub-steps:

Step 204a: Taking the time-domain sampling points of the NR uplink channel as the granularity, filter out the set of NR uplink sampling points in the part where NR and LTE have Overlap, and set it as set A (the first set of NR uplink sampling points); and The NR uplink sampling point set of another part of LTE without Overlap is also screened out and set as set B (the second NR uplink sampling point set).

Step 204b: Lower the transmission power of the first set of NR sampling points (set A) in the Overlap part by a first power value. In one embodiment, the transmission power of the first set of NR sampling points in the above-mentioned NR can be adjusted according to the protocol to

in

Indicates the maximum total transmit power in EN-DC mode, and P _LTE indicates the original calculated value of the uplink power of the LTE uplink channel. And adjust the transmit power of the second set of NR uplink sampling points to (P _NR -X _SCALE ), where P _NR represents the original calculated value of the uplink power of the NR uplink channel, and X _SCALE represents the first threshold.

If the power difference between the Overlap part and the non-Overlap part is large, there will also be a problem of phase discontinuity, thereby deteriorating the detection performance on the network side. In order to overcome the above problems, when the transmission power of the NR uplink channel in the Overlap part is greatly reduced, the transmission power of the NR uplink channel in the non-Overlap part can be adaptively reduced to reduce the impact of phase discontinuity, thereby improving the success rate of NR uplink transmission. Specifically, the transmit power of the NR uplink channel of the non-Overlap part may be adjusted by setting an amplitude adjustment coefficient.

In an implementation manner, the transmit power of the above-mentioned NR second uplink sampling point set can be calculated by the following formula:

a*(P _NR -X _SCALE )

Wherein, a is an amplitude adjustment coefficient, which can be set according to simulation and actual measurement, P _NR represents an original calculated value of uplink power of an NR uplink channel, and X _SCALE represents the first threshold. The impact of the Overlap part is minimized through the above power allocation method, thereby improving the success rate of NR uplink transmission.

Wherein, the restriction methods of the amplitude adjustment coefficient include:

If the difference between the transmission power of the NR non-overlapping part and the transmission power of the NR overlapping part is greater than a first threshold value, then use the ratio of the first threshold value to the difference value as the amplitude adjustment coefficient; or

If the difference between the transmit power of the NR non-overlapping part and the transmit power of the NR overlapping part is not greater than a first threshold value, the value of the amplitude adjustment coefficient is 1.

Step 204c: The transmission power of the first set of NR uplink sampling points determined in step 204b and the transmission power of the second set of NR uplink sampling points can be spliced together in together to obtain the complete NR uplink target transmit power.
