For a better understanding of the embodiments of the present application, reference will first be made to the following:
(1) the format of the PUCCH;
as shown in table 1, a PUCCH of a New Radio (NR) communication system supports 5 different formats, and may be divided into a short format and a long format according to the number of symbols occupied in a time domain, where the short format occupies 1 to 2 symbols and the long format occupies 4 to 14 symbols.
Table 1 PUCCH format
Figure BDA0002880504710000041
(2) Generating a PUCCH sequence;
the PUCCH format 0 Sequence is a Computer Generated Sequence (CGS) Sequence of length 12, has a low Peak to Average Power Ratio (PARP), and has a single carrier characteristic. The size of the cyclic shift is determined by the initial cyclic shift and a Hybrid automatic repeat request acknowledgement (HARQ-ACK) specific cyclic shift. UCI information is carried by selection of sequences, i.e. different information is represented by different cyclic shifts of the sequences. Since sequences of different cyclic shifts are orthogonal to each other, a plurality of UEs can select their respective cyclic shifts and multiplex the same Resource Block (RB).
PUCCH format 1 does not need to carry information by cyclic shift of the sequence, which is only used for code division multiplexing of multiple users. The PUCCH format 1 uses a sequence to carry 1bit or 2bit information in the following manner: is carried on the sequence by multiplying the modulation symbols of the information to be carried with the sequence. When it is necessary to carry 1bit information, Binary Phase Shift Keying (BPSK) modulation is used, and when it is necessary to carry 2bit information, Quadrature Phase Shift Keying (QPSK) modulation is used, and then the modulation symbols are multiplied by the sequence to form a modulation sequence with length of 12.
Since there are many Uplink Control Information (UCI) to be carried by PUCCH format 2, a method of carrying Information by using different cyclic shifts of sequences cannot be adopted, and only a transmission method of UCI + Demodulation reference signal (DMRS) can be used. The bit sequence after channel coding is mapped to RE after scrambling and modulation. The UCI information of PUCCH format 2 is not subjected to Discrete Fourier Transform (DFT) precoding, that is, a Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform is used, and a modulation method is fixed by Quadrature Phase Shift Keying (QPSK) and pi/2-BPSK is not used, because the PARP requirement for reducing PUCCH format 2 is not considered.
PUCCH format 3 uses DFT-s-OFDM waveform, and in order to further reduce PARP, pi/2-BPSK is introduced, and specifically, whether pi/2-BPSK or QPSK is used is indicated by high-layer parameters. The PUCCH format 3 also does not adopt a mode of carrying information by sequence cyclic shift, and a bit sequence after channel coding is mapped to RE after scrambling, modulation and DFT precoding.
PUCCH format 4 supports code division multiplexing, i.e., may be multi-user multiplexed. The UCI supports multi-user multiplexing by Spreading, so that the modulated sequence needs to be spread to support code division multiplexing, i.e. the bit sequence that is channel coded needs to be mapped to the resource after scrambling, modulation, Block-wise Spreading (Block-wise Spreading) and DFT precoding. And the DMRS realizes multi-user multiplexing through cyclic shift of sequences, so that a predefined relationship exists between an orthogonal sequence and the cyclic shift of the DMRS in UCI spreading.
(3) Sequence mapping of PUCCH;
PUCCH format 0 occupies 1 or 2 symbols in the time domain and all 12 subcarriers of 1 RB in the frequency domain, without DMRS. The generated length-12 sequence is directly mapped to 12 REs of the PRB.
The PUCCH format 1 occupies 12 subcarriers in the frequency domain, occupies 4-14 symbols in the time domain, is a long format PUCCH, and can configure frequency hopping within a slot, where the number of symbols in the first hop is the total number of symbols divided by 2 and rounded down, and the remaining symbols are in the second hop. For resource mapping, when the UCI and the DMRS are mapped to the REs, the UCI and the DMRS in PUCCH format 1 are spaced apart, and occupied symbols are equally divided as much as possible, that is, the DMRS only occupies OFDM symbols with even indices in PUCCH (starting with the first symbol index being 0) regardless of whether frequency hopping is configured.
The DMRS generation formula of PUCCH format 2 is the same as that of PUSCH of CP-OFDM waveform, and the DMRS and UCI are in frequency division multiplexing mode, which is different from format 1. PUCCH format 2 occupies any value of 1-16 RBs in frequency domain, DMRS density is 3, namely 3 REs in one RB are occupied by DMRS, and the rest REs are UCI. And 1 or 2 symbols are occupied in the time domain, and the short PUCCH is obtained.
The PUCCH format 3 occupies the number of RBs whose values are the product of powers of 2,3, and 5 in 1-16 RBs in the frequency domain (this setting is based on DFT precoding operation efficiency considerations), occupies 4-14 symbols in the time domain, is a long PUCCH, and occupies all subcarriers in the RB by time division multiplexing of DMRS and UCI, which is similar to PUCCH format 1.
PUCCH format 4 frequency domain occupies all 12 subcarriers of 1 RB, the time domain is the same as format 3, 4-14 symbols, is a long format PUCCH, and likewise DMRS and UCI are time division multiplexed, and the location configuration of DMRS is the same as format 3.
(4) The structure of Interlace;
the communication system introduces PRB-based interlace structure for PUCCH formats 0,1,2 and 3, wherein formats 0 and 1 support 1 interlace, and formats 2 and 3 support at most 2 interlaces. One interlace contains 10 or 11 PRBs. There are a maximum of 10 candidates for interlace for 15kHz and a maximum of 5 candidates for interlace for 30 kHz.
(5) Configuration of PUCCH frequency domain resources
The PUCCH resources comprise common resource configuration and special resource configuration, the common resource configuration obtains the configuration of frequency domain resources according to the following table 2 and the signaling of RRC, the signaling PUCCH-ResourceCommon of RRC designates a certain row in the table, and then obtains the starting position of PRB according to the CCE of the detected DCI, the carried PUCCH resource indication signaling, the PRB offset and the PRB size of BWP. Since only PUCCH formats 0 and 1 can be provided in the common resource configuration, that is, the size of the frequency domain resource is 1 PRB, the position of the frequency domain resource can be obtained after the starting position of the PRB is specified.
Table 2 PUCCH resource set before dedicated PUCCH resource configuration
Figure BDA0002880504710000071
The dedicated frequency domain Resource allocation determines a starting PRB of a first frequency hopping (or when no frequency hopping is available) through a Radio Resource Control (RRC) signaling starting PRB, determines a starting PRB of a second frequency hopping (or when no frequency hopping is available), and can determine the frequency domain Resource position for the formats 0,1 and 4 of only one PRB.
(6) Limitation of PSD;
the PSD (spectral Power density) is the average Equivalent thermal band Radiated Power (EIRP) during transmission, and the maximum PSD is specified to be 23dBm/Hz over a 60GHz band.
(7) Sub-carrier space (SCS) of 52.6 GHz.
A communication system may support at least 120kHz, and then the bandwidth of one PRB is 1.44MHz, so the power spectral density cannot be enhanced if the PRB based interlace structure of the communication system.
The PUCCH transmission method and apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.
Fig. 2 is a flowchart illustrating a PUCCH transmission method provided in an embodiment of the present application, where the method is applied to a target communication device, and as shown in fig. 2, the method includes the following steps:
step 200, determining PRB configuration information for configuring a plurality of sub-physical resource blocks;
the PRB configuration information is used for transmitting a Physical Uplink Control Channel (PUCCH);
one sub-physical resource block contains a number of resource elements, REs, that is less than or equal to the number of REs contained by one PRB.
Optionally, the sub-physical resource block may be a sub-PRB and may also be referred to as a sub-PRB;
optionally, the sub-physical resource blocks are also called partial physical resource blocks.
Optionally, since the frequency domain resources of the existing PUCCH formats 0,1,4 are fixed to 1 PRB, the transmit power is limited due to PSD limitation, which is much less than 40dBm, and the power spectral density cannot be enhanced by the PRB based interlace structure of NR-U, which may affect the PUCCH coverage; therefore, the present application proposes a PUCCH frequency domain resource configuration scheme and a mapping scheme supporting allocation of multiple sub-physical resource blocks, which are used for transmitting the PUCCH.
It should be noted that the PUCCH transmission method provided in the present application is applicable to configuration and transmission of PUCCH in all formats, or any one format or any multiple suitable configurations and transmissions, which is not limited in this embodiment.

In the embodiment of the application, by determining that the PRB configuration information of a plurality of sub-physical resource blocks is used for transmitting a Physical Uplink Control Channel (PUCCH), the PRB physical resource blocks supporting the PUCCH are a plurality of sub-physical resource blocks, the transmission bandwidth is increased, and the transmission power of the PUCCH is increased under the condition that the PSD is fixed; and on the basis of increasing the transmission bandwidth, the actual power spectral density of the SIGNAL is increased based on the configuration mode of the sub-physical resource blocks, so that the SIGNAL-to-NOISE RATIO (SNR) is increased, and the coverage rate is improved.
