The following explains some concepts and/or terms involved in the resource location determining method, apparatus, user equipment and storage medium provided in the embodiments of the present application.

1. PUCCH Format 4 and DMRS

The PUCCH is a channel carrying Uplink Control Information (UCI), and the PUCCH of the NR communication system supports 5 different formats, where PUCCH format 4 (hereinafter, referred to as PF 4) is a long PUCCH, and may occupy 4 to 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain, and may occupy 1 PRB in a Frequency domain, and a bit number carried by the UCI is greater than 2 bits (bits).

The PF4 Resource is obtained through configured Radio Resource Control (RRC) parameters of a high-level signaling, the frequency domain Resource determines a starting PRB of a first frequency hopping (or when no frequency hopping is carried out) and a starting PRB of a second frequency hopping through RRC signaling, and the frequency domain Resource position can be determined for a PUCCH with only one PRB; the number of symbols and the starting symbol index may determine the position of the time domain symbol of PF 4.

The signal processing flow of the PF4 includes a Block-spreading (Block-spreading) and precoding transformation (Transform precoding) process, so that the PUCCH can have a comb-like structure in the frequency domain, and different PUCCHs of UEs can implement frequency division multiplexing on the same PRB. The orthogonal cover code Length (occ-Length) is used to determine the number of REs included in each comb structure, e.g., occ-Length can be {2,4}, the orthogonal cover code Index (occ-Index) is used to determine the RE position included in each comb structure, e.g., occ-Index can be {0,1} or {0,1,2,3}. For example, as shown in fig. 2, occ-Length =2, occ-index =0 configured for UE 1, and occ-index =1 configured for UE 2.

The PF4-DMRS is determined by a low Peak to Average Power Ratio (PAPR) sequence, different initial cyclic shifts determine different cyclic shifts of the sequence for the low PAPR sequence of the type 1, and the sequences of the different cyclic shifts are orthogonal, that is, different UEs can transmit different sequences of the cyclic shifts for code division multiplexing on the same PRB resource. And for a low PAPR sequence of type 1, the initial cyclic shift of PF4-DMRS is determined by higher layer signaling occ-Length and occ-Index.

And the time domain symbol position of the PF4-DMRS is determined according to whether the DMRS is configured, whether frequency hopping is configured and the length of the PUCCH. The frequency domain of PF4-DMRS is 1 PRB.

2. Enhancement of multiple PRBs for PUCCH format 4

In the NR system, a larger subcarrier spacing SCS is introduced, which is 120/480/960kHz respectively, and the frequency domain resources of continuous RBs are supported for the enhanced PUCCH format 0/1/4 at present. For enhanced PF4 at 120kHz, it is not certain to support full or partial REs per RB. For PF4-DMRS, a low PAPR sequence of type 1 is supported, and the length of the low PAPR sequence is equal to the total number of REs occupied by PUCCH resources.

3. Power limitation of unlicensed spectrum

Spectral Power Density (PSD) is an average Equivalent thermal band Radiated Power (EIRP) during transmission, and the radio frequency transmission Power does not exceed the maximum EIRP, and can be obtained from the bandwidth occupied by the PSD and the PUCCH.

The resource location determining method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

Currently, for enhanced PF4 at 120kHz, it is not certain to support full or partial REs per RB. However, under the PSD limitation of the unlicensed spectrum, DMRSs based on a comb (comb) structure (sub-PRB) can effectively increase the coverage performance of PUCCH, and increase user multiplexing capacity, which is a possible supporting structure. For DMRSs of comb structures, it needs to determine/indicate which comb structure (including the number of REs and RE positions in the comb structure) to use.

The embodiment of the application provides a frequency domain position determining/indicating mode of the DMRS based on the comb structure aiming at the condition that the resource of the PUCCH format 4 comprises a plurality of continuous sub PRBs, so that the PUCCH-DMRS of different UEs can be subjected to frequency division multiplexing on the same PRB resource, and the coverage is effectively increased.

An embodiment of the present application provides a method for determining a resource location, and fig. 3 shows a flowchart of the method for determining a resource location provided in the embodiment of the present application. As shown in fig. 3, a resource location determining method provided by an embodiment of the present application may include the following step 201.

Step 201, when the frequency domain resource of the DMRS is on multiple PRBs, the UE determines the positions of REs occupied by the DMRS on the multiple PRBs.

In the embodiment of the application, the DMRS is a DMRS of a target PUCCH.

In the embodiment of the application, for the DMRS based on the comb structure, under the condition that the frequency domain resource of the DMRS includes a plurality of consecutive PRBs, the UE may determine the positions of REs occupied by the DMRS on the PRBs, so that the PUCCHs of different UEs may implement frequency division multiplexing on the same PRB.

Optionally, in this embodiment of the application, the target PUCCH may be a PUCCH in a target format, for example, PUCCH format 4 (i.e., PF 4), and may also be a PUCCH in another format, which is not limited in this embodiment of the application.

Optionally, in this embodiment of the application, the position of the RE occupied by the DMRS on each PRB of the multiple PRBs is determined by configuration information of the target PUCCH.

It can be understood that the UE may receive configuration information sent by the network side device to determine, according to the configuration information, the positions of the REs occupied by the DMRS on each PRB of the multiple PRBs, that is, the positions of the REs occupied by the DMRS on each PRB of the multiple PRBs are configured or indicated by the configuration information of the network side device.

Specifically, as shown in fig. 4 with reference to fig. 3, before the step 201, the resource location determining method provided in the embodiment of the present application further includes the following step 202 and step 203, and the step 201 may be specifically implemented by the following step 201 a.

Wherein each of the plurality of offset numbers is an offset number between a RE with a smallest index among REs occupied by one PRB of the plurality of PRBs and the RE with the smallest index in the one PRB.

It is to be understood that each of the plurality of offset numbers respectively corresponds to one PRB of the plurality of PRBs; for each PRB, one PRB (for example, PRB 1) includes multiple REs, the REs occupied by the DMRS on this PRB1 are N REs, the smallest-indexed RE in the N REs is a second RE, the smallest-indexed RE in this PRB1 (that is, the smallest-indexed RE in multiple REs in PRB 1) is a third RE, then the offset number corresponding to PRB1 is the offset number between the second RE and the third RE, and N is a positive integer.
