Background
In the process of uplink concurrency of a New Radio (NR) and a Long Term Evolution (LTE) of a Non-Standalone Networking (NSA) of a mobile communication terminal, the NR and the LTE both have respective transmission powers and timings, and if the two Overlap in time (Overlap) and the sum of the two transmission powers of the Overlap part exceeds a limit range, the transmission of the NR of the Overlap part needs to be processed.
In general, the conventional treatments are: according to the related description in 3GPP protocol 38.213/38.101-3, the maximum value of the sum of NR and LTE transmission power under NSA different scenes is (E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR, EN-DC)
And (E-UTRA NR dual connectivity with MCG using NR and SCG using E-UTRA, NE-DC)
. The sum of NR and the Overlap part transmission power of LTE directly reduces the NR transmission power once exceeding the maximum value configured above; and under EN-DC, if the NR sending power descending amplitude exceeds the maximum descending amplitude set value (X) of the NR uplink channel powerSCALE) The NR transmission can be directly abandoned. Since the channel for NR uplink transmission is likely to be important, directly reducing the transmission power even dropping the transmission results in the degradation of the connection performance of the NR link under NSA, and in severe cases, NR cannot even stay in the network or drop the network.

Detailed Description
In order to make the objects, 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 with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, when the NR terminal performs uplink transmission of NR and LTE under NSA, it may first determine whether there is an Overlap in uplink channel transmission of NR and LTE in time, then determine whether a sum of uplink transmission powers of NR and LTE in an Overlap portion exceeds a limit, and then adjust the uplink channel transmission power of NR in the Overlap portion to ensure that the sum of uplink transmission powers of NR and LTE does not exceed a range. For this reason, the conventional treatments are: when performing uplink transmission of NR and LTE under NSA, once it is determined that there is an Overlap in time of uplink channel transmission of NR and LTE, and the sum of uplink transmission power of NR and LTE in the Overlap part exceeds the limit range, the uplink transmission power of NR in the Overlap part is unconditionally reduced regardless of EN-DC or NE-DC, and even when the power is reduced more, the transmission of NR is abandoned.
Fig. 1 is a flowchart of a protocol processing procedure for allocating uplink transmission power of NR and LTE under NSA in the prior art, and as shown in fig. 1, according to descriptions of section 7.6 of 3GPP 38.213 protocol and section 6.2B of 38.101-3 protocol, in the process of allocating uplink transmission power of NR and LTE under NSA, the following steps are required:
step 101: in the NSA uplink concurrent phase, it is determined whether there is an Overlap in time for the NR and LTE uplink channel transmissions, step 102 is executed if there is no Overlap in time for the NR and LTE uplink channel transmissions, and step 103 is executed if there is an Overlap in time for the NR and LTE uplink channel transmissions.
Step 102: the NR performs allocation of transmission power.
Step 103: the current NSA type is determined, and step 104 is performed if the NSA type is NE-DC, and step 105 is performed if the NSA type is EN-DC.
Step 104: adjusting the transmitting power of the NR and LTE uplink channel Overlap part time sampling point to the transmitting power of the NR and LTE uplink channel Overlap part time sampling point according to a protocol
。
Step 105: determining whether a channel transmitted on NR needs to be dropped (Drop), upon determining that the sum of the overhead portion NR and the uplink transmission power of LTE exceeds a limit (i.e., determining that the sum of the uplink transmission power of NR and LTE exceeds a limit range)
) Then, step 106 is executed, if it is determined that the sum of the NR of the Overlap portion and the uplink transmission power of the LTE does not exceed the limit range (i.e. it is determined that the sum of the NR of the Overlap portion and the uplink transmission power of the LTE does not exceed the limit range)
) Then step 107 is performed.
Step 106: the channel sent on the NR is dropped (Drop).
Step 107: adjusting the transmitting power of the NR and LTE uplink channel Overlap part time sampling point to the transmitting power of the NR and LTE uplink channel Overlap part time sampling point according to a protocol
Thereafter, step 102 is performed.
In the above NR uplink transmission power control scheme in the prior art, if an important channel (e.g. PRACH) is transmitted on the NR, the power is reduced or even the transmission is abandoned, which has a large impact on the connection performance of the NR uplink.
In order to overcome the above technical problem, embodiments of the present application provide an uplink channel transmission power allocation method, where the uplink channel transmission power allocation method may be applied to an application scenario in which NR and LTE are concurrent under NSA, that is, may include an NE-DC scenario and an EN-DC scenario.
The technical scheme provided by the embodiment of the application can be executed by user equipment in the above scenario, for example, an NR terminal. Furthermore, under the condition that the connection performance of the RRC Connect state LTE uplink is not influenced, the transmission power of the NR uplink and the LTE Overlap part is optimally set, so that the connection performance of the NR uplink is enhanced. The problem that the connection performance of the NR link is reduced or even the transmission of the NR uplink channel is broken in order to ensure the connection performance of the LTE link is avoided.
Fig. 2 is a flowchart of an uplink channel transmission power allocation method according to an embodiment of the present application, and as shown in fig. 2, the power allocation method includes the following steps:
step 201: in the NSA uplink concurrent phase, it is determined whether there is an Overlap in time between the NR to be transmitted and the uplink channel of LTE, if there is no Overlap, step 202 is executed, and if there is an Overlap, step 203 is executed.
Step 202: the transmission power of NR and LTE is allocated separately.
Step 203: determining whether the descending amplitude of the sending power of the first NR uplink channel within the overlapping time exceeds a first threshold, if not, executing step 202, and if the descending amplitude exceeds the first threshold, executing step 204.
Step 204: the method comprises the steps of reducing the transmitting power of an NR first uplink sampling point set of an Overlap part by a first power value to obtain NR overlapped part transmitting power, determining NR non-overlapped part transmitting power based on the reduction result of reducing the transmitting power of an NR second uplink sampling point set by a second power value in the overlapping time, and splicing the NR overlapped part transmitting power and the NR non-overlapped part transmitting power to obtain NR uplink target transmitting power.
In the specific implementation of step 201, at the stage of determining whether there is an Overlap between NR and LTE, according to the chronological order, immediately before a certain NR/LTE uplink channel is transmitted, an uplink channel (i.e., known and not-yet-transmitted other LTE/NR uplink channels) in the time period of the uplink channel to be transmitted is determined, and whether there is an Overlap in time is determined.
Wherein determining that there is an overlap in time between NR and LTE uplink channel transmissions may comprise:
determining an uplink channel to be transmitted according to a time sequence, if the uplink channel to be transmitted is an NR uplink channel, determining whether an LTE uplink channel overlapped with a transmission time period of the NR uplink channel to be transmitted exists in other uplink channels which are not transmitted, and if the LTE uplink channel exists, determining that the NR to be transmitted and the LTE uplink channel are overlapped in time; or
Determining an uplink channel to be transmitted according to a time sequence, if the uplink channel to be transmitted is an LTE uplink channel, determining whether an NR uplink channel overlapping with a transmission time period of the LTE uplink channel to be transmitted exists in other uplink channels which are not transmitted, and if the NR uplink channel exists, determining that the NR to be transmitted and the LTE uplink channel overlap in time.
According to the determination result, if there is no Overlap in the uplink channel transmission of NR and LTE in time, step 202 is executed, and if there is Overlap in the uplink channel transmission of NR and LTE in time, step 203 is executed.
Fig. 2a is a schematic diagram of an Overlap over uplink channel time of NR and LTE according to an embodiment of the present application, as shown in fig. 2a, that is to say, at t0~t5Transmits the first NR uplink channel at t0~t5In the time period of (1), there is an Overlap between the uplink channel of the LTE which is not transmitted and the first NR uplink channel to be transmitted in time, and the corresponding Overlap parts are t2~t3Time period and t4~t5A time period.
In other embodiments, it may also be determined whether an Overlap exists in the time between the first NR uplink channel to be transmitted and the LTE uplink channel being transmitted, or whether an Overlap exists in the time between the LTE uplink channel to be transmitted and the first NR uplink channel being transmitted. As shown in fig. 2a, there is an Overlap between the first NR uplink channel to be transmitted and the LTE uplink channel being transmitted, and the corresponding portion of the Overlap is t0~t1A time period.
In the specific implementation of step 202, according to the determination result of step 201, after it is determined that there is no Overlap in uplink channel transmission of NR and LTE, NR and LTE may be respectively allocated to their respective transmission powers. Based on the determination of step 203, atDetermining that the sum of the transmission power of all uplink channels of the Overlap part of the NR and LTE uplink channels in time does not exceed the maximum total transmission power of NSA
Then NR and LTE may be assigned respective transmit powers separately. Or the sum of the transmission power of all uplink channels of an Overlap part of the time for determining the uplink channel transmission of NR and LTE exceeds the maximum total transmission power of NSA
And reducing the transmission power of the NR uplink channel of the Overlap part, wherein the reduction amplitude is less than a first threshold value (X)SCALE) In the case of (3), the transmission power of the LTE uplink channel is not changed, that is, power allocation is performed according to the original calculated value of LTE uplink power, and the transmission power of the overlay partial NR uplink channel is allocated with the reduced transmission power.
Before performing step 203, the following steps may also be performed:
determining whether the sum of the transmit powers of all uplink channels within the overlapping time exceeds the NSA maximum total transmit power:
if the sum of the transmission power of all uplink channels in the overlapped time does not exceed the maximum total transmission power of NSA, the uplink channels of NR to be transmitted and LTE are respectively subjected to power distribution according to respective original calculated values of uplink power;
if the sum of the transmission powers of all the uplink channels in the overlapped time exceeds the maximum NSA transmission total power, reducing the transmission power of the NR uplink channel, determining whether the reduction amplitude of the transmission power of the NR uplink channel exceeds a first threshold value, and if the reduction amplitude does not exceed the first threshold value, performing power distribution on the NR uplink channel 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 NSA maximum total transmit power comprises: and taking the sampling points of the time domain of the uplink channel to be transmitted as granularity, and judging whether the sum of the transmission power of all the uplink channels in the overlapped time exceeds the maximum transmission total power of the NSA one by one according to the time sequence. Specifically, it may be determined whether the sum of the transmission powers of the NR uplink channel to be transmitted and the LTE uplink channel not to be transmitted exceeds the NSA maximum total transmission power according to the sampling point set S2 and the sampling point set S3 shown in fig. 2 a.
In the specific implementation of step 203, it is determined whether the sum of the transmission powers of all uplink channels within the overlapping time (Overlap portion) exceeds the maximum total transmission power NSA
If the maximum total transmission power of NSA is not exceeded
Then step 202 is executed, if the maximum total transmission power of NSA is exceeded
Then step 204 is performed.
In the implementation of step 204, step 204 may include the following sub-steps:
step 204 a: taking time domain sampling points of an NR uplink channel as granularity, screening a set of NR uplink sampling points in a part of NR and LTE with Overlap, and setting the set as a set A (NR first uplink sampling point set); and screening a set of NR uplink sampling points which do not have Overlap with the LTE, and setting the set as a set B (NR second uplink sampling point set).
Step 204 b: the sending power of the first NR uplink sampling point set (set a) of the Overlap part is adjusted to be lower by a first power value, and in one embodiment, the sending power of the first NR uplink sampling point set may be adjusted to be lower by a protocol
Wherein
Representing the maximum total power transmitted in EN-DC mode,
and the original calculated value of the uplink power of the LTE uplink channel is shown. And adjusting the transmitting power of the NR second uplink sampling point set to
Wherein, in the step (A),
representing the original calculated value of the uplink power of the NR uplink channel,
representing the first threshold.
If the power difference between the Overlap part and the non-Overlap part is large, the problem of discontinuous phase also occurs, thereby deteriorating the detection performance of the network side. In order to overcome the above problems, when the transmission power of the NR uplink channel in the Overlap portion is reduced more, the transmission power of the NR uplink channel in the non-Overlap portion may be adaptively reduced to reduce the influence caused by phase discontinuity, thereby improving the success rate of NR uplink transmission. Specifically, the non-Overlap partial NR uplink channel transmission power may be adjusted by setting an amplitude adjustment coefficient.
In one embodiment, the transmit power of the NR second uplink sampling point set may be calculated by the following formula:
wherein a is an amplitude adjustment coefficient which can be set according to simulation and actual measurement,
representing the original calculated value of the uplink power of the NR uplink channel,
representing the first threshold. By the above workThe rate allocation method reduces the influence of the Overlap part to the minimum, thereby improving the success rate of NR uplink transmission.
Wherein, the limiting mode of the amplitude adjustment coefficient comprises the following steps:
if the difference between the NR non-overlapping part transmission power and the NR overlapping part transmission power is larger than a first threshold value, taking the ratio of the first threshold value to the difference as the amplitude adjustment coefficient; or
If the difference between the NR non-overlapping transmission power and the NR overlapping transmission power is not greater than a first threshold, the amplitude adjustment coefficient takes a value of 1.
Step 204 c: the transmission power of the NR first set of uplink sampling points and the transmission power of the NR second set of uplink sampling points determined in step 204b (NR overlapping portion transmission power and NR non-overlapping portion transmission power) may be spliced together to obtain a complete NR uplink target transmission power.
