[0029] The communication systems applicable to the embodiments of this application include, but are not limited to, long-term evolution (LTE) systems, 5th-generation (5G) systems, NR systems, and future evolution systems or multiple converged communication systems. The 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solutions of this application are also applicable to different network architectures, including but not limited to relay network architectures, dual-link architectures, and vehicle-to-everything (V2X) architectures.

[0030] This application mainly relates to sidelink communication between terminal devices. Specifically:

[0031] In this application, "terminal equipment" can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication equipment, user agents, or user devices. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application does not limit the scope of these terms. Terminal equipment can also be called user equipment (UE), terminal, etc.

[0032] As described in the background section, enhancing the information carried by the PSFCH means increasing the number of resource blocks (RBs) occupied by the existing PSFCH to multiple, which will affect the power allocation scheme of the PSFCH.

[0033] The present invention provides a method for determining PSFCH power. Since the number of resource blocks occupied by PSFCH will affect the power of PSFCH resources, when determining the power, it is necessary to take into account the total number of resource blocks occupied by PSFCH of each priority as a factor to ensure the accuracy of PSFCH resource power allocation and thus ensure the reliability of PSFCH transmission.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] See Figure 1 The methods provided in this application include:

[0036] Step 101: Determine the priority of each PSFCH;

[0037] Step 102: Determine the power of each PSFCH resource based at least on the first total number of resource blocks occupied by each PSFCH of each priority.

[0038] It should be noted that the sequence number of each step in this embodiment does not represent a limitation on the execution order of each step.

[0039] It is understood that, in specific implementations, the PSFCH power determination method can be implemented using a software program, which runs in a processor integrated within the chip or chip module.

[0040] In this embodiment, the PSFCH power determination method can be used in the transmitting device in sidelink communication, that is, the terminal device that sends PSFCH.

[0041] In this embodiment, the number of PSFCHs, the resources occupied by PSFCHs, the PSSCHs carried by PSFCHs, and the priority of each PSSCH can be pre-configured by the network-side device or the sending user equipment. Specifically, the number of resource blocks occupied by a PSFCH and the number of PSSCHs carried by a PSFCH can be one or more.

[0042] In the specific implementation of step 101, the maximum value of the priority in the PSSCH corresponding to the HARQ-ACK bits carried by each PSFCH resource is determined, and used as the priority of the PSFCH resource.

[0043] Specifically, since each PSFCH resource carries multiple PSSCHs corresponding to HARQ-ACK bits, and each PSSCH has a corresponding priority, there are multiple priorities for each PSFCH. In this case, the maximum priority of these multiple PSSCHs can be selected as the PSFCH priority. This ensures that the PSFCH has a higher priority, allowing it to be sent out first and guaranteeing the reliability of sending higher-priority PSSCHs.

[0044] It should be noted that in practical application scenarios, other methods can also be used to determine the priority of PSFCH. For example, the minimum priority value of the PSSCH corresponding to the HARQ-ACK bits carried by each PSFCH resource can be selected as the priority of the PSFCH resource; or, the priority value of the PSSCH corresponding to the HARQ-ACK bits carried by each PSFCH resource can be randomly selected as the priority of the PSFCH resource. This embodiment of the invention does not limit this.

[0045] In the specific implementation of step 102, depending on whether the network side configures higher-layer parameters, the terminal device uses different methods to determine the power of the PSFCH resources.

[0046] When higher-layer parameters are provided, the terminal device can first use the higher-layer parameters to calculate the power of a single PSFCH resource; then calculate the sum of the power of a single PSFCH resource and the first total value in the log field; and determine the power of each PSFCH resource based on the relationship between the total number of PSFCHs scheduled for transmission and the upper limit of PSFCHs that can be sent simultaneously, as well as the relationship between the above sum and the power of the scheduled PSFCHs.

[0047] Specifically, the higher-level parameters include a first higher-level parameter dl-P0-PSFCH and a second higher-level parameter dl-Alpha-PSFCH. The first higher-level parameter dl-P0-PSFCH can indicate parameters. The value indicates that the power reaching the base station is used as the configuration criterion for power (p0). The second higher-layer parameter dl-Alpha-PSFCH can indicate the parameter. The value of .

[0048] In one specific embodiment, the power of a single PSFCH resource is calculated using the following formula:

[0049] (1)

[0050] in, This indicates the power of the PSFCH resource at index k. This represents the value of the first high-level parameter. This indicates the value of the second high-level parameter. Indicates the subcarrier spacing and / or cyclic prefix (CP) type. This indicates the number of resource blocks occupied by the PSFCH resource with index k, and PL represents the path loss.

[0051] It should be noted that when the second high-level parameter dl-Alpha-PSFCH is not provided, The value of PL is 1. The value of PL can be determined by referring to clause 7.1.1 of the communication standard protocol: The following two cases are exceptions: 1. When the UE is configured to monitor the Physical Downlink Control Channel (PDCCH) to detect Downlink Control Information (DCI) in format 0_0, the Reference Signal (RS) resource is the resource used by the UE to determine the transmission power of the Physical Uplink Shared Channel (PUSCH) scheduled by the DCI in format 0_0; 2. When the UE is not configured to monitor the PDCCH to detect DCI in format 0-0, the RS resource is the resource corresponding to the Synchronization Signal (SS) / Physical Broadcast Channel (PBCH) block used by the UE to acquire the Master Information Block (MIB).

[0052] In a non-limiting embodiment of the present invention, when providing the higher-layer parameter dl-P0-PSFCH, the following four cases can be distinguished based on the relationship between the total number of PSFCHs scheduled for transmission and the upper limit of PSFCHs that can be sent simultaneously, as well as the relationship between the first power and the power of the scheduled PSFCHs, as detailed below.

[0053] Situation 1 and satisfy ,So , .

[0054] in, M i,k This indicates the number of resource blocks occupied by the PSFCH resource with index k and priority i.

[0055] In other words, if the total number of PSFCHs scheduled for transmission is less than the upper limit of PSFCHs that the UE can send simultaneously, and the sum of the power of the PSFCH resource at index k and the first total number in the Log field is less than or equal to... When the transmission power of each PSFCH is equal, the power of the PSFCH resource with priority i and index k is equal to the power of the PSFCH resource with index k.

[0056] It should be noted that this can be determined according to the communication standard protocol [8-1, TS38.101-1]. PSFCH transmission power .

[0057] Scenario 2 And not satisfied Then the number of UEs selected is The PSFCH is determined, and the power of the PSFCH resource with priority i and index k is determined. for , chosen satisfy .

[0058] In this embodiment, the UE determines the order in ascending priority according to clause 16.2.4.2 of the communication standard protocol. One PSFCH transmission, making , K is the number of PSFCHs with priority value i, and K is defined as satisfying The largest value of N, where It is determined according to the communication standard protocol [8-1, TS38.101-1] and is used to transmit all PSFCHs assigned priority values ​​1, 2, ..., K, if any.

[0059] Situation 3 Then the number of UEs can choose is The PSFCH satisfies the following conditions in ascending order of priority. At that time, determine , ;

[0060] Situation 4 Then the number of UEs selected is The PSFCH does not satisfy the order in ascending priority. When, select a quantity of The PSFCH is determined, and the power of the PSFCH resource with priority i and index k is determined. for , chosen satisfy ;

[0061] In this embodiment, the UE determines the order in ascending priority according to clause 16.2.4.2 of the communication standard protocol. One PSFCH transmission, making , K is the number of PSFCHs with priority value i, and K is defined as satisfying The largest value of N, where It is determined according to the communication standard protocol [8-1, TS38.101-1] and is used to transmit all PSFCHs assigned priority values ​​1, 2, ..., K, if any.

[0062] In the power calculation formulas for the above situations, The parameters N and M can be pre-configured by the base station. N can represent the number of priority levels of the PSFCH, and M can represent the number of PSFCH indexes.

[0063] In another non-limiting embodiment of the invention, when high-level parameters are not provided, the method is directly based on... The transmission power of each PSFCH and the actual number of PSFCHs transmitted are used to determine the power of the PSFCH resource with priority i and index k in the log field. The specifics are as follows.

[0064] Case 5: When the high-level parameter dl-P0-PSFCH is not provided. .

[0065] In this embodiment, the UE determines the order in ascending priority according to clause 16.2.4.2 of the communication standard protocol. One PSFCH transmission, making ,in It is determined according to the communication standard protocol [8-1, TS38.101-1]. PSFCH transmission power.

[0066] Please refer to Figure 2 , Figure 2 This illustrates an exemplary interaction process between network devices and terminal devices.

[0067] In step 201, the network-side device configures higher-layer parameters for the user and sends them to terminal device 1. Terminal device 1 here refers to the device that needs to send the PSFCH.

[0068] Specifically, the higher-level parameters can be either the first higher-level parameter dl-P0-PSFCH or the second higher-level parameter dl-Alpha-PSFCH. Higher-level parameters may also include the number of PSFCHs, the resources occupied by each PSFCH, the PSSCHs carried by each PSFCH, and the priority of each PSSCH.

[0069] In step 202, terminal device 1 calculates the power of each PSFCH resource.

[0070] In step 203, terminal device 1 sends the PSFCH to terminal device 2. Here, terminal device 2 refers to the most critical terminal device that needs to receive the PSFCH.

[0071] Specifically, the communication method between terminal device 1 and terminal device 2 is side link communication.
