Description
Technical Field
The invention relates to the field of 5G base stations, in particular to the field of msg3 power control parameters, and specifically relates to a method, a device, a processor and a computer readable storage medium for realizing adjustment processing of msg3 power control parameters of a base station.
Background
In the 5G age, the number of UE is increased, the access number of the base station to the UE is increased, the access time delay is shortened, and the access success rate is required to be higher. The access time delay and the access success rate are affected by the aspects of UE, base station related configuration and processing, air interface transmission loss and the like. In the 5G protocol, a 4-step random access flow based on competition is shown in fig. 1, wherein a first step ue initiates a random access request, msg1; secondly, the base station transmits a random access response, msg2; third, ue sends rrc setup request, msg3 according to the configuration in msg2; fourth, the base station transmits contention resolution, msg4.
In the random access process, the analysis of msg3 has larger influence on the random access: multiple analysis failures tend to trigger msg3 to retransmit for multiple times, so that access delay side length is caused; and if the number of times of retransmission is exceeded, the success rate of access is reduced. The uplink power configuration parameter of the base station to msg3 affects the uplink power sent by msg3, and further affects the analysis of the base station to msg 3. This configuration parameter is issued to the UE by the tpc value in the msg2 message. When normal UE performs random access, the user end calculates downlink loss according to SSB of MIB as reference signal, and adjusts own transmitting power. On the base station side, after the access is completed, the path loss of the UE can be estimated by accumulating the csi rs measurement report, but in the random access flow, the base station is difficult to reversely estimate the path loss at the moment.

if the power value P_adjust to be adjusted is smaller than-6 or larger than 8, continuing the step (4); if the power value P_adjust to be adjusted is greater than or equal to-6 and less than or equal to 8, continuing with step (6).
As a preferred embodiment of the present invention, in the step (4), the msg3 power adjustment threshold value is used as the msg3 power adjustment value of the UE, and specifically includes the following steps:
judging whether the power value P_adjust to be adjusted is smaller than-6, if so, adjusting the power value P_adjust to be adjusted to-6; otherwise, the power value p_adjust to be adjusted is adjusted to 8.
As a preferred embodiment of the present invention, the step (5) specifically includes the steps of:
(5.1) judging whether the power value P_adjust to be adjusted is smaller than-6, if so, adding 1 to the value of the preamble transmission times C, and continuing the step (5.2); otherwise, subtracting 1 from the preamble transmission times C, and continuing the step (2);
(5.2) judging whether the preamble transmission times C is less than or equal to the maximum possible preamble transmission times N, if so, continuing the step (2); otherwise, taking the maximum possible preamble transmission times N as preamble transmission times C, and continuing the step (2).
As a preferred embodiment of the present invention, the method further includes a step of initializing the base station before the UE accesses, specifically including the following steps:
the base station calculates and obtains a group of preamble target power value tables ordered according to the preamble transmission times by broadcasting parameters informing the UE of the preamble receiving target power, the preamble power climbing step length and the maximum preamble transmission times of the current base station.
The device for realizing the adjustment processing for the msg3 power control parameter of the base station comprises:
a processor configured to execute computer-executable instructions;
and a memory storing one or more computer executable instructions which, when executed by the processor, implement the steps of the method for implementing adjustment processing for the msg3 power control parameter of the base station.
The processor for implementing the adjustment processing for the msg3 power control parameter of the base station according to the present invention is configured to execute computer executable instructions, which when executed by the processor implement the steps of the above-described method for implementing the adjustment processing for the msg3 power control parameter of the base station.
The computer readable storage medium of the present invention has stored thereon a computer program executable by a processor to perform the steps of the above-described method of implementing an adjustment process for a base station msg3 power control parameter.
In the specific implementation mode of the invention, the algorithm optimization is mainly carried out on the configured tpc parameter, namely the msg3 power control parameter, in the msg2 issued by the base station, so that the power of the msg3 sent by the UE is in a reasonable range, the problem of analysis failure caused by supersaturation of msg3 pusch power or too low power is reduced, thereby improving the random access success rate of the UE and reducing the access time delay of the UE.
Before the user terminal UE is accessed, the base station can inform the UE of parameters such as the PREAMBLE receiving target power, delta_preamble, the PREAMBLE power rising step length, the maximum PREAMBLE sending times and the like of the current base station through broadcasting. And obtaining a group of preamble target power value tables which are ordered according to the preamble transmission times through the parameter calculation.
When the UE is accessed, the maximum estimated path loss when the UE transmits the preamble for the first time and the possible maximum preamble transmission times N and the corresponding minimum estimated path loss of the UE are obtained by comparing the power value with a preamble target power value table calculated before according to the measured received msg1 power value. And taking the average value of the maximum and minimum values of the preamble transmission times, namely (N+1)/2, and carrying out up rounding to obtain the estimated preamble transmission times C.
The maximum preamble transmission times are configured broadcast parameters, which are the same for all UEs and are fixed values, and cannot be calculated. Here, N is the maximum possible preamble transmission number, 1< =n < =configured maximum preamble transmission number. And calculating an msg3 power adjustment value by using the estimated preamble transmission times C, and if the calculated adjustment value meets the expectations (the power value required to be adjusted is smaller than-6 or larger than 8), using the adjustment value as the msg3 power adjustment value of the UE, carrying out subsequent operation, converting into tpc and transmitting to the UE through msg2. The scaled tpc value is the message parameter contained in msg2. If the calculated msg3 power adjustment value exceeds a reasonable range, the estimated number of times C of transmitting the preamble needs to be compared for judgment.
And if the estimated transmission preamble number C is equal to 1 or equal to the maximum possible preamble transmission number N, using the msg3 power adjustment threshold value as an msg3 power adjustment value of the UE, performing tpc conversion, and using the preamble transmission number corresponding to the msg3 power adjustment threshold value as the estimated preamble transmission number. Otherwise, the number of times C of transmitting the preamble is adjusted according to the power value calculated in the previous step.
The configured maximum preamble sending times are values consistent with all users and are sent by broadcasting. N is the estimated number of preambles that the current user is most likely to transmit, and N must be less than or equal to the configuration value.
And recalculating the power value required to be adjusted for obtaining msg3 by using the new preamble transmission times C obtained by the previous estimation. And finally, re-executing the previous two steps of calculation according to the power value which is required to be regulated until a reasonable msg2 tpc parameter is obtained, and sending the msg2 tpc parameter to the target UE through an air interface.
