The technical solution of the present application is also applicable to different network architectures, including but not limited to a relay network architecture, a dual link architecture, a Vehicle-to-event architecture, and the like.

The present application relates generally to terminal devices and side link communications between terminal devices. Wherein:

a terminal equipment (terminal equipment) in the embodiments of the present application may refer to various forms of an access terminal, a subscriber unit, a subscriber station, a Mobile Station (MS), a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment. A terminal device may also be referred to as a User Equipment (UE), a terminal, or the like.

As described in the background art, enhancing information carried by the PSFCH means that the number of Resource Blocks (RBs) occupied by the existing PSFCH needs to be increased to a plurality, which affects the power allocation scheme of the PSFCH.

The technical scheme of the invention provides a PSFCH power determination method, and since the number of resource blocks occupied by PSFCH influences the power of PSFCH resources, when determining the power, the first total number of the resource blocks occupied by PSFCH of each priority level needs to be considered as a consideration factor so as to ensure the accuracy of PSFCH resource power distribution and further ensure the reliability of PSFCH transmission.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, the method provided by the present application includes:

step 101: determining the priority of each PSFCH;

step 102: and determining the power of each PSFCH resource at least according to the first total number of the resource blocks occupied by the PSFCHs of the priorities.

It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.

It is understood that, in a specific implementation, the PSFCH power determination method may be implemented by using a software program running in a processor integrated inside a chip or a chip module.

In this embodiment, the PSFCH power determining method may be used for a sending end device in side link communication (sidelink), that is, a terminal device sending the PSFCH.

In this embodiment, the number of the PSFCHs, the resources occupied by the PSFCHs, the PSSCHs carried by the PSFCHs, and the priorities of the PSSCHs may be pre-configured by the network side device or the transmitting user equipment. Specifically, the number of resource blocks occupied by the PSFCH is 1 or more, and the number of PSSCHs carried by the PSFCH is 1 or more.

In the specific implementation of step 101, the maximum value of the priority in the pschs corresponding to the HARQ-ACK bits carried by each PSFCH resource is determined as the priority of the PSFCH resource.

Specifically, since there are multiple PSSCHs corresponding to HARQ-ACK bits carried by each PSFCH resource, each PSSCH has a corresponding priority (priority), and thus there are multiple PSFCHs corresponding to priorities. In this case, the maximum value of the priorities of the pschs may be selected as the priority of the PSFCH. In this way, the PSFCH can be ensured to have higher priority, so that the PSFCH can be sent out preferentially during sending, and the reliability of PSSCH sending with higher priority is ensured.

In an actual application scenario, the priority of the PSFCH may be determined in other manners. For example, the minimum value of the priority of the pschs corresponding to the HARQ-ACK bits carried by each PSFCH resource may be selected as the priority of the PSFCH resource; or, the value of the priority of the psch corresponding to the HARQ-ACK bit carried by each PSFCH resource may also be randomly selected as the priority of the PSFCH resource, which is not limited in this embodiment of the present invention.

In the specific implementation of step 102, the terminal device determines the power of the PSFCH resource in different manners according to whether the network side configures a higher-layer parameter.

When the high-level parameters are provided, the terminal equipment can firstly utilize the high-level parameters to calculate the power of a single PSFCH resource; then calculating the sum of the power of the single PSFCH resource and the value of the first total number in the log domain; the power of each PSFCH resource is determined according to the relation between the total number of PSFCHs scheduled for transmission and the upper limit value capable of simultaneously transmitting PSFCHs and the relation between the sum and the power of the PSFCHs scheduled for transmission.

In particular, the high-level parameters include a first high-level parameter dl-P0-PSFCH and a second high-level parameter dl-Alpha-PSFCH. The first higher layer parameter dl-P0-PSFCH can indicate the parameter P _O,PSFCH Represents a configuration criterion with power arriving at the base station as power (p 0), the second higher layer parameter dl-Alpha-PSFCH being able to indicate the parameter Alpha _PSFCH The value of (c).

In a particular embodiment, calculating the power of a single PSFCH resource using the following formula includes:

P _PSFCH,k ＝P _O,PSFCH +10log ₁₀ (2 ^μ ×M _k )+α _PSFCH ×PL (1)

wherein, P _PSFCH,k Denotes the power, P, of the PSFCH resource with index k _O,PSFCH A value, a, representing said first higher layer parameter _PSFCH Represents a value of the second higher layer parameter, μ represents a subcarrier spacing and/or a cyclic prefix: (Cyclic Prefix, CP) type, M _k Denotes the number of resource blocks occupied by the PSFCH resource with index k, and PL denotes the path loss.

It should be noted that when the second high-level parameter dl-Alpha-PSFCH is not provided, alpha is _PSFCH The value of (b) is 1. The value of PL can be determined with reference to the description of communication standard agreement clause 7.1.1: PL = PL _b,f,c (q _d ) When a UE is configured to monitor a Physical Downlink Control Channel (PDCCH) to detect Downlink Control Information (DCI) of format 0_0, a Reference Signal (RS) resource is a resource that the UE uses to determine a Physical Uplink Shared Channel (PUSCH) transmission power scheduled by the DCI of format 0_0; 2. when the UE is not configured to monitor the PDCCH to detect DCI format 0-0, the RS resource is a resource corresponding to a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) Block used by the UE to acquire a Master Information Block (MIB).

In one non-limiting embodiment of the present invention, when providing the higher layer parameter dl-P0-PSFCH, the following four cases can be classified according to the relationship between the total number of PSFCHs scheduled for transmission and the upper limit value capable of transmitting PSFCHs simultaneously, and the relationship between the first power and the power of the PSFCH scheduled for transmission, which is described in detail as follows.

Case 1, N _{_sch,Tx,psfch} <N _{_max,psfch} And satisfy

Then N _Tx,psfch ＝N _{_sch,Tx,psfch} ，P _PSFCH,k (i)＝P _PSFCH,k 。

Wherein, M _i,k Indicating the number of resource blocks occupied by the PSFCH resource with index k and priority i.

That is, when the total number of PSFCHs scheduled for transmission is less than the upper limit value at which the UE can simultaneously transmit the PSFCHs, and the sum of the power of the PSFCH resource with index k and the first total number in the Log domain is less than or equal to N _{_sch,Tx,psfch} Transmission power of PSFCHThe power of the k-indexed PSFCH resource with priority i is equal to the power of the k-indexed PSFCH resource.

It should be noted that, the protocol can be based on the communication standard [8-1, TS38.101-1 ]]Determining N _{_sch,Tx,psfch} A PSFCH transmission power P _CMAX 。

Case 2, N _{_sch,Tx,psfch} <N _{_max,psfch} And do not satisfy

Then the UE selects a number N _Tx,psfch And determines the power P of the PSFCH resource with index k and priority i _PSFCH,k (i) Is P _PSFCH,k (i)＝min(P _CMAX -10log ₁₀ (N _Tx,psfch ),P _PSFCH,k ) Selected N _Tx,psfch Satisfy the requirement of

In this embodiment, the UE autonomously determines N in ascending order of priority according to the communication standard agreement clause 16.2.4.2 _Tx,psfch A PSFCH is transmitted such that

M _i Is the number of PSFCHs having a priority value of i and K is defined to satisfy

Of maximum value of N, where P _CMAX Is according to the communication standard protocol [8-1, TS38.101-1]It is determined to transmit all PSFCHs, if any, assigned priority values 1,2.

Case 3, N _{_sch,Tx,psfch} >N _{_max,psfch} Then UE autonomously selects the number as N _{_max,ps} f _c h PSFCH in ascending order of priority

Case 4, N _{_sch,Tx,psfch} >N _{_max,psfch} Then the UE selects the number N _{_max,psfch} In ascending order of priority, does not satisfy

Then, the number is selected to be N _Tx,psfch And determines the power P of the PSFCH resource with index k and priority i _PSFCH,k (i) Is P _PSFCH,k (i)＝min(P _CMAX -10log ₁₀ (N _Tx,psfch ),P _PSFCH,k ) Selected N _Tx,psfch Satisfy the requirements of

In the power calculation formulas for the above-mentioned several cases,

the parameters N and M in (1) may be pre-configured by the base station. N may represent the number of levels of priority of the PSFCH, and M may represent the number of indexes of the PSFCH.

In another non-limiting embodiment of the invention, the higher layer parameter is provided directly from N _{_sch,Tx,psfch} The transmission power of each PSFCH and the value of the number of actually transmitted PSFCHs in the log field determine the priority iThe power of the PSFCH resource with index k. The details are as follows.

Case 5, when the higher layer parameter dl-P0-PSFCH is not provided, P _PSFCH,k (i)＝P _CMAX -10log ₁₀ (N _Tx,psfch )。

In this embodiment, the UE autonomously determines N in ascending order of priority according to the communication standard agreement clause 16.2.4.2 _Tx,psfch A PSFCH is transmitted such that N _Tx,psfch Not less than 1, wherein P _CMAX Is according to the communication standard protocol [8-1, TS38.101-1]Determined N _Tx,psfch One PSFCH transmit power.

Referring to fig. 2, fig. 2 shows an exemplary interaction flow between a network device and a terminal device.

In step 201, the network side device configures high-level parameters for the user and sends the parameters to the terminal device 1. The terminal device 1 herein refers to a device that needs to transmit the PSFCH.

Specifically, the high-level parameter may be a first high-level parameter dl-P0-PSFCH, or may be a second high-level parameter dl-Alpha-PSFCH. The higher layer parameters may also include the number of PSFCHs, the resources occupied by the PSFCHs, the PSSCHs carried by the PSFCHs, the priorities of the individual PSSCHs, and the like.
