[0029] The following explains some concepts and / or terms involved in the resource location determination method, device, user equipment and storage medium provided in the embodiments of the present application.

[0030] 1. PUCCH format 4 and DMRS

[0031] PUCCH is a channel that carries uplink control information (UCI). The PUCCH of the NR communication system supports five different formats, among which PUCCH format 4 (PF4) is a long PUCCH, which can occupy 4-14 orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 1 PRB in the frequency domain. The number of bits carried by UCI is greater than 2 bits.

[0032] PF4 resources are obtained through the configured high-level signaling Radio Resource Control (RRC) parameters. The frequency domain resources are determined through RRC signaling to determine the starting PRB of the first frequency hop (or no frequency hopping) and the starting PRB of the second frequency hop. For PUCCH with only one PRB, the frequency domain resource position can be determined; the number of symbols and the starting symbol index can determine the position of the PF4 time domain symbol.

[0033] The signal processing flow of PF4 includes the processes of block-wise spreading and transform precoding, which can realize the comb-like structure of PUCCH in the frequency domain. The PUCCHs of different UEs can be frequency-division multiplexed on the same PRB. The orthogonal cover code length (occ-Length) is used to determine the number of REs included in each comb structure. For example, the value of occ-Length can be {2, 4}. The orthogonal cover code index (occ-Index) is used to determine the position of REs included in each comb structure. For example, the value of occ-Index can be {0, 1} or {0, 1, 2, 3}. For example, Figure 2 As shown, occ-Length=2, occ-index=0 configured for UE 1, and occ-index=1 configured for UE 2.

[0034] PF4-DMRS is determined by a low Peak to Average Power Ratio (PAPR) sequence. For Type 1 low PAPR sequences, different initial cyclic shifts determine different cyclic shifts of the sequence, and sequences with different cyclic shifts are orthogonal. This means that different UEs can transmit sequences with different cyclic shifts using the same PRB resources for code division multiplexing. For Type 1 low PAPR sequences, the initial cyclic shift of PF4-DMRS is determined by the higher-layer signaling occ-Length and occ-Index.

[0035] The time domain symbol position of PF4-DMRS is determined by whether DMRS is configured, whether frequency hopping is configured, and the length of PUCCH. The frequency domain of PF4-DMRS is 1 PRB.

[0036] 2. Enhancement of multiple PRBs in PUCCH format 4

[0037] In NR systems, a larger subcarrier spacing (SCS) of 120 / 480 / 960 kHz is introduced. Currently, enhanced PUCCH formats 0 / 1 / 4 support contiguous frequency domain resources (RBs). For the 120 kHz enhanced PF4, support for full or partial REs in each RB has not yet been determined. For PF4-DMRS, type 1 low PAPR sequences are supported, and the length of the low PAPR sequence is equal to the total number of REs occupied by the PUCCH resources.

[0038] 3. Power Limitation in Unlicensed Spectrum

[0039] Spectral Power Density (PSD) is the average equivalent isotropically radiated power (EIRP) during transmission. The RF transmit power does not exceed the maximum EIRP. The RF transmit power can be obtained from the PSD and the bandwidth occupied by the PUCCH.

[0040] The resource location determination method provided in the embodiments of the present application is described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] Currently, for the 120kHz enhanced PF4, whether full or partial REs in each RB are supported has not yet been determined. However, under the PSD constraints of unlicensed spectrum, a DMRS structure based on a comb (sub-PRB) can effectively improve PUCCH coverage and increase user multiplexing capacity, making it a possible support structure. For DMRS in a comb structure, the comb structure to be used (including the number and location of REs in the comb structure) needs to be determined / indicated.

[0042] In an embodiment of the present application, a frequency domain position determination / indication method of a DMRS based on a comb structure is proposed for the case where the PUCCH format 4 resource contains multiple consecutive sub-PRBs, which can enable the PUCCH-DMRS of different UEs to be frequency-division multiplexed on the same PRB resources, effectively increasing coverage.

[0043] The present invention provides a method for determining a resource location. Figure 3FIG. 1 shows a flow chart of a method for determining a resource location provided by an embodiment of the present application. Figure 3 As shown, the resource location determination method provided in the embodiment of the present application may include the following step 201.

[0044] Step 201: When the frequency domain resources of DMRS are on multiple PRBs, the UE determines the positions of REs occupied by DMRS on the multiple PRBs.

[0045] In the embodiment of the present application, the above-mentioned DMRS is the DMRS of the target PUCCH.

[0046] In an embodiment of the present application, for a DMRS based on a comb structure, when the frequency domain resources of the DMRS include multiple consecutive PRBs, the UE can determine the position of the RE occupied by the DMRS on the PRB, so that the PUCCHs of different UEs can be frequency-division multiplexed on the same PRB.

[0047] Optionally, in an embodiment of the present application, the above-mentioned target PUCCH can be a PUCCH of a target format, such as PUCCH format 4 (ie, PF4), or a PUCCH of other formats, which is not limited in the embodiment of the present application.

[0048] Optionally, in an embodiment of the present application, the above-mentioned target PUCCH carries UCI, and UCI may include at least one of the following: Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK), uplink scheduling request (Scheduling Request, SR), channel state information (Channel State Information, CSI), etc.

[0049] Optionally, in an embodiment of the present application, the position of RE occupied by the above-mentioned DMRS on each PRB in multiple PRBs can be configured or indicated by the network, or predefined, or agreed upon by the protocol, or preconfigured, or determined autonomously by the UE.

[0050] Optionally, in an embodiment of the present application, the positions of REs occupied by the above-mentioned DMRS on each PRB in multiple PRBs are the same.

[0051] Optionally, in an embodiment of the present application, the position of REs occupied by the above-mentioned DMRS on each PRB in multiple PRBs is determined by the configuration information of the target PUCCH.

[0052] It can be understood that the UE can receive the configuration information sent by the network side device to determine the position of the RE occupied by the DMRS on each PRB in multiple PRBs based on the configuration information, that is, the position of the RE occupied by the DMRS on each PRB in multiple PRBs is configured or indicated by the configuration information of the network side device.

[0053] Specific, combined Figure 3 ,like Figure 4 As shown, before the above step 201, the resource location determination method provided in the embodiment of the present application further includes the following steps 202 and 203, and the above step 201 can be specifically implemented through the following step 201a.

[0054] Step 202: The network-side device sends configuration information of the target PUCCH to the UE.

[0055] Step 203: The UE receives configuration information of the target PUCCH sent by the network side device.

[0056] Step 201a: When the frequency domain resources of the DMRS are on multiple PRBs, the UE determines the positions of the REs occupied by the DMRS on the multiple PRBs according to the configuration information of the target PUCCH.

[0057] Optionally, in an embodiment of the present application, the configuration information of the above-mentioned target PUCCH may be configured by a higher layer.

[0058] Optionally, in an embodiment of the present application, the number of REs occupied by the above-mentioned DMRS on each PRB in multiple PRBs and the RE interval are determined by the orthogonal cover code length (occ-length) in the configuration information of the target PUCCH.

[0059] It can be understood that the configuration information sent by the network side device includes the orthogonal cover code length. The UE can determine the number of REs occupied by DMRS on each PRB in multiple PRBs and the RE interval based on the orthogonal cover code length, that is, the number of REs occupied by DMRS on each PRB in multiple PRBs and the RE interval are configured or indicated by the configuration information of the network side device.

[0060] Optionally, in an embodiment of the present application, the multiple PRBs correspond to multiple offset numbers, and the multiple PRBs correspond to the multiple offset numbers one-to-one; the multiple offset numbers are determined by the orthogonal cover code index (occ-index) in the configuration information of the target PUCCH or by the UE itself. Each of the multiple offset numbers is the offset number between the RE with the smallest index among the REs occupied by a PRB in the multiple PRBs and the RE with the smallest index in the PRB.

[0061] It can be understood that each of the multiple offset numbers corresponds to a PRB in multiple PRBs; for each PRB, a PRB (for example, PRB1) includes multiple REs, and the REs occupied by DMRS on the PRB1 are N REs, the RE with the smallest index among the N REs is the second RE, and the RE with the smallest index in the PRB1 (that is, the RE with the smallest index among the multiple REs in PRB1) is the 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.

[0062] In an embodiment of the present application, the configuration information sent by the network side device includes an orthogonal cover code index. The UE can determine the multiple offset numbers corresponding to multiple PRBs based on the orthogonal cover code index, that is, the multiple offset numbers are configured or indicated by the configuration information of the network side device.

[0063] For example, Figure 5 The figure shows the position of the REs occupied by DMRS on each PRB. occ-length = 2, occ-index = 0 configured for UE 1, and occ-index = 1 configured for UE 2. The position of DMRS is determined by occ-length and occ-index. The number of REs occupied by DMRS is 12 / 2 = 6, and the number of REs between each two REs is 2-1 = 1. The offset between the RE with the smallest index and the first RE is 0 or 1, where the offset is 0 for UE 1 and 1 for UE 2.

[0064] Optionally, in an embodiment of the present application, the position of REs occupied by the above-mentioned DMRS on each PRB in multiple PRBs is determined by a sub-PRB pattern configured in a UE-specific RRC parameter.

[0065] Optionally, in an embodiment of the present application, the above-mentioned sub-PRB pattern is configured by a bitmap.

[0066] For example, Figure 6 The figure shows the positions of the REs occupied by DMRS on each PRB. The bitmap of the DMRS configured by the higher layer for UE 1 is 101010101010, and the bitmap for UE 2 is 010101010101, where 1 represents occupied RE resources and 0 represents unoccupied RE resources. The bits in the bitmap are REs with increasing indexes from left to right. For example, the bitmap 101010101010 represents the occupancy of REs with indexes 1 to 12.

[0067] Optionally, in an embodiment of the present application, the above-mentioned sub-PRB pattern is determined by a comb index and a comb length.

[0068] Optionally, in an embodiment of the present application, the comb index and comb length may be configured by a high level layer.

[0069] Optionally, in an embodiment of the present application, the comb index is used to determine the number of offsets between a first RE and a RE with the smallest index in a PRB where the first RE is located, where the first RE is the RE with the smallest index in a sub-PRB pattern.

[0070] Optionally, in an embodiment of the present application, the comb length is used to determine the number of REs and RE intervals included in the sub-PRB pattern.

[0071] For example, Figure 7 The figure shows the position of the REs occupied by DMRS on each PRB. The frequency domain of PF4-DMRS (i.e., DMRS of PUCCH format 4) of each symbol occupies 12 / 4=3 REs, i.e., comb-length=4, and the interval between each two REs is 4-1=3. The offset number between the RE with the smallest index among the 3 REs and the RE with the smallest index in the PRB is 2, i.e., comb-index=2.

[0072] Optionally, in an embodiment of the present application, the RE positions occupied by the above-mentioned DMRS in different PRBs among multiple PRBs are related to the index of the PRB.

[0073] It can be understood that the positions of REs occupied by different PRBs are determined by the index of each PRB in the different PRBs.

[0074] Optionally, in an embodiment of the present application, the positions of REs occupied by the above-mentioned DMRS in multiple PRBs are determined by the number of PRBs and network configuration or indication.

[0075] Optionally, in an embodiment of the present application, the PRB pattern corresponding to the above-mentioned multiple PRBs is determined by the comb index, the comb length and the number of PRBs.

[0076] For example, Figure 8 As shown in the figure, the positions of the REs occupied by the four PRBs are shown. The number of PRBs configured by the high-level layer for PF4 is 4, and comb-length is configured as 8, so there are a total of 4*12=48 REs. The frequency domain of PF4-DMRS occupies 48 / 8=6 REs, and the interval between each two REs is 8-1=7, and comb-index=2 (i.e., the offset number between the RE with the smallest index among the 6 REs and the RE with the smallest index in the PRB is 2).

[0077] Optionally, in an embodiment of the present application, the PRB patterns corresponding to the above-mentioned multiple PRBs are determined by the bit maps of all REs in the multiple PRBs.

[0078] Optionally, in an embodiment of the present application, the above-mentioned number of PRBs is directly configured by a higher layer.

[0079] Optionally, in an embodiment of the present application, the bitmaps of all REs in the above-mentioned multiple PRBs are directly configured by a higher layer.

[0080] Optionally, in an embodiment of the present application, the comb index is used to determine the RE with the smallest index in the PRB pattern and the offset number of the RE with the smallest index in multiple PRBs.

[0081] Optionally, in an embodiment of the present application, the comb length is used to determine the number of REs and RE intervals included in the PRB pattern.

[0082] Optionally, the resource location determination method provided in the embodiment of the present application further includes the following step 301.

[0083] Step 301: The UE determines the PRB position occupied by the DMRS on multiple PRBs.

[0084] Optionally, in an embodiment of the present application, the PRB position occupied by the above-mentioned DMRS on multiple PRBs is configured or indicated by the network, or is predefined, or is agreed upon by the protocol, or is preconfigured, or is determined autonomously by the UE.

[0085] It should be noted that the present embodiment does not limit the order in which steps 201 and 301 are performed. In one case, step 201 may be performed first, followed by step 301; in another case, steps 201 and 301 may be performed simultaneously; and in yet another case, step 301 may be performed first, followed by step 201.

[0086] An embodiment of the present application provides a resource location determination method. When the frequency domain resources of the DMRS of the target PUCCH are on multiple PRBs, the UE can determine the location of the REs occupied by the DMRS on the multiple PRBs. In this solution, for a DMRS with a comb structure, the UE can determine the location of the REs occupied by the DMRS on the multiple PRBs to determine which REs on the multiple PRBs the DMRS specifically uses, and to determine which comb structure the DMRS specifically uses, so as to effectively increase the coverage performance of the PUCCH and improve the UE multiplexing capacity, while enabling the PUCCH-DMRS of different UEs to be frequency-division multiplexed on the same PRB resources.

[0087] It should be noted that the resource location determination method provided in the embodiments of the present application can be executed by a UE, or a resource location determination device, or a control module in the resource location determination device for executing the resource location determination method. In the embodiments of the present application, the resource location determination device provided in the embodiments of the present application is described by taking the UE executing the resource location determination method as an example.

[0088] Figure 9 FIG. 1 shows a possible structural diagram of a resource location determination device involved in an embodiment of the present application. Figure 9 As shown, the resource location determining device 60 may include: a determining module 61.

[0089] The determining module 61 is configured to determine the positions of REs occupied by the DMRS on multiple PRBs when the frequency domain resources of the DMRS are on multiple PRBs, and the DMRS is the DMRS of the target PUCCH.

[0090] In a possible implementation, the position of REs occupied by the DMRS in each of the multiple PRBs is the same.

[0091] In one possible implementation, combining Figure 9 ,like Figure 10 As shown, the resource location determination device 60 provided in the embodiment of the present application further includes: a receiving module 62. The receiving module 62 is configured to receive the configuration information of the target PUCCH sent by the network side device before the determination module 61 determines the location of the REs occupied by the DMRS on the multiple PRBs when the frequency domain resources of the DMRS are on multiple PRBs. The location of the REs occupied by the DMRS on each of the multiple PRBs is determined by the configuration information of the target PUCCH.

[0092] In a possible implementation, the number of REs and the interval between REs occupied by the DMRS in each of the multiple PRBs are determined by the orthogonal cover code length in the configuration information of the target PUCCH.

[0093] In one possible implementation, the above-mentioned multiple PRBs correspond to multiple offset numbers, and the multiple PRBs correspond one-to-one to the multiple offset numbers; the multiple offset numbers are determined by the orthogonal cover code index in the configuration information of the target PUCCH or by the UE independently; wherein each offset number in the multiple offset numbers is the offset number between the RE with the smallest index among the REs occupied by one PRB in the multiple PRBs and the RE with the smallest index in the one PRB.

[0094] In a possible implementation, the position of REs occupied by the DMRS on each PRB in a plurality of PRBs is determined by a sub-PRB pattern configured in a UE-specific RRC parameter.

[0095] In a possible implementation manner, the sub-PRB pattern is configured by a bit map; or, the sub-PRB pattern is determined by a comb index and a comb length.

[0096] In one possible implementation, the comb index is used to determine the number of offsets between the first RE and the RE with the smallest index in the PRB where the first RE is located, where the first RE is the RE with the smallest index in the sub-PRB pattern; the comb length is used to determine the number of REs and RE intervals contained in the sub-PRB pattern.

[0097] In a possible implementation manner, the RE positions occupied by the DMRS in different PRBs among multiple PRBs are related to the index of the PRB.

[0098] In a possible implementation, the positions of REs occupied by the DMRS in multiple PRBs are determined by the number of PRBs and network configuration or indication.

[0099] In a possible implementation, the PRB pattern corresponding to the above-mentioned multiple PRBs is jointly determined by the comb index, the comb length and the number of PRBs; or, the PRB pattern corresponding to the above-mentioned multiple PRBs is determined by the bit map of all REs in the multiple PRBs.

[0100] In one possible implementation, the number of PRBs is directly configured by a higher layer; the bitmap of all REs in the multiple PRBs is directly configured by a higher layer; the comb index is used to determine the offset number of the RE with the smallest index in the PRB pattern and the RE with the smallest index in multiple PRBs; the comb length is used to determine the number of REs and RE intervals contained in the PRB pattern.

[0101] In one possible implementation, the above-mentioned determination module is also used to determine the PRB position occupied by DMRS on multiple PRBs; wherein the PRB position occupied by DMRS on multiple PRBs is configured or indicated by the network, or is predefined, or is agreed upon by the protocol, or is preconfigured, or is determined autonomously by the UE.

[0102] An embodiment of the present application provides a resource location determination device. For a comb-structured DMRS, the resource location determination device can determine the position of the REs occupied by the DMRS on multiple PRBs, so as to determine which REs on multiple PRBs are specifically used by the DMRS, and to determine which comb structure is specifically used by the DMRS, so as to effectively increase the coverage performance of the PUCCH, improve the UE multiplexing capacity, and enable the PUCCH-DMRS of different UEs to be frequency-division multiplexed on the same PRB resources.

[0103] The resource location determination device in the embodiments of the present application may be a device, a device or UE with an operating system, or a component, integrated circuit, or chip in the UE. The device or UE may be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may include but is not limited to the types of UE 11 listed above, and the non-mobile terminal may be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), an ATM or a self-service machine, etc., which is not specifically limited in the embodiments of the present application.

[0104] The resource location determination device provided in the embodiment of the present application can implement each process implemented in the above method embodiment and achieve the same technical effect. To avoid repetition, it will not be described here.

[0105] Alternatively, as Figure 11 As shown, an embodiment of the present application also provides a communication device 500, including a processor 501, a memory 502, and a program or instruction stored in the memory 502 and executable on the processor 501.
