Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
In 5G _ NR, the PUCCH is used for transmitting uplink physical layer control Information (UCI) as in 4G _ LTE, and the control Information that may be carried includes "uplink scheduling request SR", "ACK/NACK Information for downlink data", and "downlink channel state Information CSI feedback". According to the length of the PUCCH and the size of the UCI load, FMT1 in 5G is still used for bearing SR and ACK, if a user has uplink data to send, a scheduling request SR is sent to a base station eNB, and after the eNB detects that the uplink data needs to be sent, uplink resources are allocated to the user terminal for data transmission. On the other hand, the eNB does not know when the terminal needs uplink resources, and therefore needs to periodically detect whether the terminal has a scheduling request SR to transmit. The eNB side only detects whether energy exists on corresponding resources to judge whether the SR exists, namely, the SNR is calculated according to the calculated user signal power and the calculated noise power, the SNR is compared with a corresponding threshold, and if the SNR is larger than the threshold, the SR is detected to be transmitted through activation detection; similarly, the ACK/NACK needs to be detected by signal power and noise power, and is detected to be de-ACK/NACK, and is not detected by default if the detection is not activated. Fig. 1 shows a flowchart for calculating PUCCH noise power in an LTE system, which specifically includes the following steps:
1) after the pilot frequency and the data signal are combined, calculating respective power of the pilot frequency and the data signal;
2) sum power in the pilot and data signal antenna direction;
3) except the signal path, 6 paths with the smallest unoccupied space are found;
4) if yes, calculating the average value of the 6 paths as the noise power;
5) if not, the empty 6 paths are filled up and the average value is calculated as the noise power.
When the number of users in a cell is small, a plurality of users do not use the same WALSH code on the same PRB, so that only six paths with the minimum signal power in 11 paths except the user path are selected even if signals are leaked, the noise power calculation is relatively accurate, and the phenomenon of missing detection caused by large noise power calculation rarely occurs; when the number of users in a cell is large, a single cell has 600 users, and even more, because bandwidth resources are saved, multiple users can multiplex one WALSH code, and when the same WALSH code in the same PRB is occupied by more than 6 users, the signal power of other users can be taken as effective noise power to influence final noise power calculation, so that the noise power is larger, and other users can be influenced similarly.
The embodiment of the application is different from the original LTE implementation scheme in noise power calculation on the aspect of selecting noise paths, the method does not adopt the method of finding the minimum unoccupied 6 paths in 12 paths where a user is located to calculate the average value as the noise power, but according to the PRB, how many paths on the WALSH code are occupied by other users, the paths occupied by other users are eliminated, and the unoccupied paths are adopted as the noise paths to calculate the average value as the noise power of the user.
Referring to fig. 2, a noise power calculation method provided in an embodiment of the present application includes:
s101, aiming at a Physical Resource Block (PRB) occupied by a current terminal, determining the diameter of the PRB occupied by other terminals using the same WALSH code with the current terminal;
for an uplink timeslot, the system may invoke multiple PRBs to support the service requirements of multiple users (or terminals) according to the number of users in the current cell, for example, 28 users are allocated to one PRB, and another 14 users are allocated to another PRB.
S102, determining the PRB paths which are not occupied by the current terminal and other terminals according to the PRB paths occupied by the current terminal and other terminals;
the path of the PRB occupied by the current terminal and other terminals is a user signal path, and the path of the PRB not occupied by the current terminal and other terminals is a noise path (the noise path refers to a tap which is regarded as noise in 12 taps after completion of WALSH combining in a time domain after IDFT, wherein the tap is the path).
S103, calculating the noise power of the current terminal according to the PRB paths which are not occupied by the current terminal and other terminals.
The noise includes internal noise and external noise; internal noise may be a system internal factor resulting in impure transmission signals; external noise is introduced by external factors as the signal propagates through the medium.
Optionally, determining, according to the paths of the PRBs occupied by the terminal and other terminals, the paths of the PRBs not occupied by the terminal and other terminals, specifically including:
setting the power of the path of the PRB occupied by the terminal and other terminals to 0, and then setting the path of the PRB whose power is not set to 0 as the path of the PRB not occupied by the terminal and other terminals.
Setting the power of the path of the PRB occupied by the terminal and other terminals to 0, namely excluding the path of the PRB occupied by the terminal and other terminals from the noise path used for calculating the noise power.
Optionally, calculating the noise power of the terminal according to the path of the PRB not occupied by the terminal and other terminals, specifically including:
and accumulating the power of the PRB paths which are not occupied by the terminal and other terminals and calculating an average value, wherein the average value is the noise power of the terminal.
Optionally, the noise power of other terminals in the PRB using the same WALSH code as the current terminal is determined as the noise power of the current terminal.
That is, in the same PRB, the noise power of all terminals using the same WALSH code is the same, so when multiple terminals use the same WALSH code, the noise power of only one of the terminals needs to be calculated, which is equivalent to calculating the noise power of all terminals in the WALSH code.
Referring to fig. 3, a flowchart for calculating PUCCH noise power in 5G _ NR provided in the embodiment of the present application includes:
step one, after resource demapping is performed on a PUCCH signal, Inverse Discrete Fourier Transform (IDFT) is changed from a Frequency domain to a time domain, and after WALSH is decoded, averaging all Orthogonal Frequency Division Multiplexing (OFDM) symbols in the same slot of the obtained time domain data and pilot data, that is, after WALSH is combined, only one row of data and one row of pilot are left (that is, 14 OFDM symbols in the time domain, 7 possible data in 14 symbols, 7 pilot, data on 7 pilot are accumulated and averaged, and data on 7 data symbols are accumulated and averaged, and viewed from the Frequency domain as only one row of pilot signal and one row of data signal). The signal power of the column of data and the pilot frequency are respectively calculated.
And step two, calculating the sum power of the pilot frequency and the data signal in the antenna direction. And C, according to the result in the step I, performing accumulative averaging on the pilot frequency and the data signal in the row among the antennas, combining the power of the data row and the power of the pilot frequency row after the antenna direction averaging is completed (calculating the average value after the accumulation is performed), and only remaining one row of power.
Step three, when the number of users in a cell is large, there may be 36 users at most in one PRB, and there may also be other users at most, where the PUCCH-FMT1 in NR has 7 WALSH codes at most, and different users may occupy the same WALSH code and different cyclic shifts (that is, multiple users may use the same WALSH code, and multiple users may be located on different paths through different cyclic shifts), so the PRB where the current user is located is determined according to the resource record set corresponding to the user in the PRB recorded in the scheduling process, and the signal paths occupied by other users except for the current user are determined in 12 paths of the lswah code occupied by the current user.
And step four, eliminating the signal paths of the PRBs occupied by all the users using the WALSH code (the paths occupied by the users are the signal paths) in the current PRB, namely setting the power of the signal paths of the PRBs occupied by all the users using the WALSH code in the current PRB to be 0, and eliminating the signal paths from the noise paths used for calculating the noise power.
Step five, the path with the power not set to 0 is the noise path of the current user, other noise paths not set to 0 are accumulated and the average value is calculated, and the obtained average value is the noise power of the current user; in the current PRB, when multiple users use the same WALSH code, the noise power of one user is calculated, which is equivalent to calculating the noise power of any other user in the WALSH code, and the noise power is recorded, and then the users in the WALSH code can not calculate the noise power according to the marks, so that the increase of the whole time consumption caused by repeated calculation is avoided.
The noise power calculation method provided by the embodiment of the application can accurately calculate the noise power of each user when the number of users in the FMT1 format is large in PUCCH single-slot scheduling, so that missed detection and false detection of SR and ACK are reduced, SR and ACK loss caused by wrong activation detection judgment are reduced, and uplink PUCCH power control adjustment is facilitated.
