Description

SNR estimation method of PUCCH (physical uplink control channel) for 5G base station system
Technical Field
The invention relates to the field of communication, in particular to an SNR estimation method of a PUCCH (physical uplink control channel) for a 5G base station system.
Background
In the 5G NR standard, physical layer channels thereof are divided into an uplink channel and a downlink channel, where HARQ feedback information ACK/NACK of downlink data channel information and a resource scheduling request SR are transmitted on an uplink control channel PUCCH format 0/1/2/3/4. The terminal may have a discontinuous transmission behavior, i.e. DTX, due to scheduling and resource requirements, etc., and the base station PUCCH format0/1 has no CRC check behavior during reception, so it is necessary to exclude DTX first. Generally, when DTX detection is performed, a signal-to-noise ratio (SNR) of a received signal needs to be estimated first, and the SNR is compared with a preset threshold to determine whether DTX exists. However, the existing SNR estimation method is completed based on a known reference signal, for a 5G NR system, pucch format1/2/3/4 has a reference signal, and pucch format0 has no reference signal, and a general SNR calculation method cannot be operated. On the other hand, the pucch format0 supports resource multiplexing of multiple users, that is, multiple users transmit signals on the same time-frequency resource, and the base station side receives the sum of the signals of the multiple users, which also makes SNR calculation cumbersome.
Estimating the SNR requires separate computation of the signal power and the noise power, which is a difficult point. There are two main types of existing solutions. Firstly, assuming that all users are supposed to transmit signals, estimating a channel first, thereby obtaining a received signal of each user, subtracting the sum of the signal powers of all users from the total signal power of the base station, and the rest is noise. If the user does not transmit a signal, the estimated signal energy is a small value, but the theoretical value is 0, so that the signal power sum of all users has errors, which results in errors in the calculation of noise power and SNR, and especially when there is some user DTX in multi-antenna reception, the estimation error is large. Secondly, when a pucch format0 signal of a certain user is received, noise estimation is not performed, but a historical noise power value stored in the system is used for replacing the historical noise power value, and only the signal power of the user needs to be calculated, namely, the SNR can be calculated, and the scheme has larger error because the instantaneous noise power cannot be obtained.

and 7: comparing the SNR of each user with a preset SNR threshold to obtain whether the user has DTX; and for the user without DTX, obtaining corresponding sending information according to the sequence cyclic offset corresponding to the maximum value of the signal power.
2. The method of claim 1, wherein in step 5, the set M of candidate cyclic offsets for each user is determinedsetDetermining the sequence cyclic offset set m of each user according to the multiplexing situation of HARQ and SR of the usercsCyclically shifting the sequence by a set mcsWith the initial cyclic offset m of each user0Adding to obtain a candidate cyclic offset set M of each usersetThe method comprises the following steps:
calculating a set of candidate cyclic offsets for each user u, setting the configured initial cyclic offset to scalar m0The result of the calculation is

1) If the user only has SR information, then
mcs＝{0}Mset＝{m0+0}
2) If the user only has 1 bit HARQ information, then
mcs＝{0,6}，Mset＝{m0+0,m0+6}
3) If the user only has 2-bit HARQ information, then
mcs＝{0,3,6,9}，Mset＝{m0+0,m0+3,m0+6,m0+9}
4) If the user has 1-bit HARQ information and may have SR, then
mcs＝{0,3,6,9}，Mset＝{m0+0,m0+3,m0+6,m0+9}
5) If the user has 2-bit HARQ information and may have SR, then
