Description

Technical Field

[0001] The present application relates to the field of data communication technology, and in particular to a power determination method, user equipment and computer-readable storage medium. Background Art

[0002] At present, there are two air interface technologies for SideLink (SL) communication, namely 4G Long Term Evolution (LTE) technology and 5G New Radio (NR) technology. In the future, SL communication using the sixth-generation mobile communication technology (6G) may appear. SL can work in unlicensed frequency bands, called unlicensed sidelink (SideLink Unlicensed, SL-U); the unlicensed frequency band uses a listen before talk (LBT) bandwidth of about 20M as the frequency domain unit, and a physical sidelink feedback channel (PSFCH) transmission frequency domain of SL-U is located within an LBT bandwidth. In the case where the frequency domain needs to meet the occupied channel bandwidth (OCB) requirements, SL-U defines two formats for PSFCH; one of them is that PSFCH transmission adopts the form of shared interleaved resource blocks (RB) combined with dedicated RBs, and the device transmits useful feedback information on the dedicated RBs and transmits channel occupancy signals on the shared interleaved RBs. In addition, the device may send multiple PSFCHs simultaneously during the PSFCH feedback period. These PSFCHs have different priorities and may be located in the same or different LBT bandwidths. Therefore, in areas with OCB requirements in unlicensed frequency bands, considering the OCB requirements and power spectrum density (PSD) restrictions, how to determine the number of resources and power for PSFCH transmission to ensure that the number of simultaneously transmitted PSFCH transmissions does not exceed the maximum transmission power of the device, nor does it exceed the maximum number of PSFCH transmissions of the device is a problem to be solved. Summary of the invention

Specifically, the use of words such as "exemplary", "for example" or "for example" is intended to present related concepts in a specific way.

[0030] In order to facilitate understanding of the solutions of the embodiments of the present application and to provide a clear and concise description of the following embodiments, a brief introduction to the relevant technology is first given.

[0031] See also Figure 1 In the sidelink (SL) communication system, when there is a service to be transmitted between user equipment (UE), the service data between UEs does not pass through the network side, that is, it does not pass through the cellular link between the UE and the base station, but is directly transmitted from the data source UE to the target UE through the SL. Through the above method, the burden on the cellular network can be reduced, the battery power consumption of the user equipment can be reduced, and the robustness of the network infrastructure can be improved, which can well meet the requirements of high data rate services and proximity services, and also supports direct communication in scenarios without network coverage, which can meet special communication needs such as public safety, where the device works on the resources defined by the communication resource pool.

[0032] See also Figure 2 , multiple nominal channel bandwidths are defined on the unlicensed spectrum, each of which is 20M. When a device works on the unlicensed spectrum, it needs to listen on the defined nominal channel bandwidth, and can transmit signals on the nominal channel only when the channel is idle. The nominal channel bandwidth can be divided according to the frequency domain. For example, the nominal channel bandwidth is divided according to the bandwidth size of 20M on a section of unlicensed spectrum, so that multiple nominal channel bandwidths can be obtained.

[0033] Generally speaking, when the device is working, it uses at least 1 20M bandwidth. Some areas have occupied bandwidth (OCB) requirements for the nominal channel bandwidth defined on the unauthorized basis, that is, the device needs to occupy at least 80% of the frequency domain resources on the nominal channel bandwidth. Since OCB is a regional requirement, SL-U performs frequency domain structure design for both with and without OCB requirements during the analysis process; the subsequent embodiments of this application mainly focus on explaining the channel structure with OCB requirements and the corresponding method for calculating the transmission power of the physical sidelink feedback channel (PSFCH).

[0034] In the channel structure definition of SL-U, a channel structure of resource block set (RB set) is proposed. The resource block set is similar to the concept of nominal bandwidth defined in the unlicensed mode, which is about 20M. In addition, the OCB requirements must also be met in the same RBset. The frequency domain of the PSFCH feedback channel defines two formats in the RB set. Please refer to Figure 3 and Figure 4 .exist Figure 3 The format of the PSFCH shared interleaved resource block (RB) and one dedicated physical resource block (PRB) is shown in FIG. Figure 4 The format of the PSFCH dedicated interleaved RB is shown in FIG. Figure 3 In the format shown, in the current RB set, when a device transmits PSFCH, it needs to transmit signals on both the shared interleaved RB and the dedicated PRB. The purpose of transmitting signals on the shared interleaved PRB is to meet the OCB requirements, and the dedicated PRB transmits useful information that the PSFCH needs to carry. The shared interleaved PRB positions of all devices in the RB set are the same, and the dedicated PRB resource positions may be different. Figure 4 In the format shown, in the current RB set, when the device transmits PSFCH, the useful information is directly carried on a dedicated interleaved RB on the RB set. The dedicated interleaved RB resource locations of different UEs may be different. It is worth noting that the embodiments of the present application are mainly based on Figure 3 The power is determined under the channel structure shown.

[0035] It should be noted that the interleaving on the RB set is 11 or 10 PRBs with equal intervals in the RB set; under the subcarrier spacing (SCS) of 15kHz, there are 10 interleavings on an RB set; under the SCS of 30kHz, there are 5 interleavings on each RB set. In the time domain, PSFCH appears in the SL communication resource pool according to a certain period. A PSFCH time domain opportunity is often associated with multiple SL data transmissions in the past. Therefore, the device may need to transmit multiple PSFCH resources simultaneously in the PSFCH time slot. These PSFCH resources may be located in the same RB set or different RB sets. Since multiple PSFCHs in the frequency domain may be discrete in the frequency domain and the UE's transmission power is limited, when the device transmits PSFCH, if the number of scheduled PSFCH transmissions or the device's transmission power does not meet the requirements, it is necessary to adjust the number and power of PSFCH transmissions according to the priority of PSFCH transmission so that the device can successfully transmit multiple PSFCH resources. The embodiments of the present application mainly illustrate a method for determining power and resources based on the format of PSFCH shared interleaved RBs and dedicated PRBs.

[0036] See also Figure 5 For the PSFCH format of shared interleaved RB and K3 dedicated PRBs, the shared interleaved RB occupies one interleaved in the RB set, and all UEs can transmit signals on this shared interleaved to meet the OCB requirements on the RB set. The K3 dedicated PRBs are located on another interleaved, and the dedicated PRBs between UEs are generally considered to be orthogonal. The value of K3 is configurable, and it is generally believed that K3 can be 1, 2, 5, etc. Figure 5 , when K3 is equal to 2, UE1's PSFCH transmission and UE2's PSFCH transmission. Figure 5 As shown, when UE1 transmits PSFCH on RB set, it sends signals on 10 equally spaced shared interleaved PRBs and 2 UE1 dedicated PRBs. When UE2 transmits PSFCH on RB set, it sends signals on 10 equally spaced shared interleaved PRBs and 2 UE2 dedicated PRBs.

[0037] See also Figure 6 UE1 can also transmit one PSFCH on two RB sets respectively. For each RBset, UE1 sends signals on 10 equally spaced shared interleaved RBs and 2 UE1-specific PRBs.

[0038] It should be noted that the signaling of SL-U in the embodiment of the present application can be obtained through configuration or pre-configuration, and no limitation is made here; the configuration in the embodiment of the present application can include network configuration equipment, equipment configuration another equipment, or pre-configuration.

[0039] For PSFCH transmission on SL, downlink power control may be enabled or not, depending on the configuration or preconfigured parameters. In either case, the PSFCH transmission transmitted by the UE on the PSFCH opportunity needs to meet the following conditions: The number of PSFCH transmissions actually transmitted by the UE on a PSFCH feedback opportunity N Tx,PSFCH Not exceeding the maximum number of PSFCH transmissions N of the UE max,PSFCH ; The actual transmission power of the UE at the PSFCH feedback opportunity (considering the total power of the shared interleaved RB and the dedicated PRB) does not exceed the configured UE maximum transmission power; When the UE transmits PSFCH on the dedicated PRB in the RB set, it may be necessary to transmit signals on the configured or pre-configured shared interleaved RB at the same time in order to meet the OCB requirements. It is worth noting that the pre-configuration in this application may include pre-definition, configuration and pre-configuration.

[0040] In order to solve the problem that the user equipment may send multiple PSFCHs at the same time during the PSFCH feedback opportunity, these PSFCHs have different priorities and may be located in the same or different LBT bandwidths, so in the area with OCB requirements in the unlicensed frequency band, the OCB requirements and the power spectrum density (PSD) are considered. How to determine the number of resources and power of PSFCH transmission to ensure that the number of PSFCH transmissions transmitted simultaneously does not exceed the maximum transmission power of the device, nor does it exceed the maximum number of PSFCH transmissions of the device, the embodiment of the present application provides a power determination method, user equipment and computer-readable storage medium. In the embodiment of the present application, the PSFCH to be transmitted is first determined, wherein each PSFCH includes a shared interleaved resource block and a dedicated resource block; according to the number of PSFCHs to be transmitted and the number of shared interleaved resource blocks N1 corresponding to the PSFCH to be transmitted, the transmit power of each PSFCH to be transmitted can be determined. Through the scheme of the embodiment of the present application, the transmit power of each PSFCH transmission is determined while meeting the maximum number of PSFCH transmissions of the user equipment, the maximum transmit power of the device and the channel occupancy requirements.

The terminal device may also be a smart phone, a desktop computer, a tablet computer, a laptop, a smart TV, an intelligent voice interaction device, a smart home appliance, etc., and may also be other terminal devices such as smart transportation equipment, smart home equipment, a robot, and a drone.

[0042] The execution subject of the power determination method of the embodiment of the present application can be a server. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms. This embodiment of the present application is not limited to this.

For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules.

In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0044] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on the attribute information or attribute information set of an object (such as a user, etc.) and other data related to the characteristics of the object, the permission or consent of the corresponding object will be obtained first, and the collection, use and processing of these data will comply with relevant laws, regulations and standards.

After clearly obtaining the separate permission or separate consent of the corresponding object, the relevant data of the object necessary for the normal operation of the embodiment of the present application is obtained.

[0045] The power determination method, user equipment and computer-readable storage medium provided in the embodiments of the present application are specifically illustrated through the following embodiments. First, the power determination method in the embodiments of the present application is described.

[0046] See also Figure 7 , Figure 7 Schematic diagram of the steps of a power determination method provided in an embodiment of the present application. Figure 7As shown, the power determination method includes the following steps S110 to S120, and each step is introduced in turn below:

[0047] Step S110, determining at least one PSFCH to be transmitted at a physical side link feedback channel PSFCH transmission opportunity, each of the PSFCH to be transmitted includes at least one dedicated resource.

[0048] In an embodiment of the present application, in the process of determining power, it is first necessary to determine the PSFCH to be transmitted, and each PSFCH to be transmitted is transmitted through a corresponding resource block group, and the resource block group includes at least one dedicated resource block; wherein, the resource block group referred to in the embodiment of the present application is the above-mentioned resource block set RB set, and the dedicated resource block refers to the above-mentioned dedicated PRB. In some embodiments, in order to meet the OCB requirements, the RB set of the PSFCH to be transmitted also has the corresponding shared interleaved resource block of the PSFCH to be transmitted, and the shared interleaved resource block is the above-mentioned shared interleaved RB. In the process of determining power in an embodiment of the present application, the PSFCH transmission adopts the form of shared interleaved resource blocks and dedicated resource block groups.

[0049] In an embodiment of the present application, the number of dedicated resource blocks carried by each PSFCH in a resource block group is not fixed. For example, there may be 1, 2 or 5 dedicated resource blocks in a resource block group, etc.; and each dedicated resource block corresponds to a corresponding user device, that is, the user device will only transmit data on the dedicated resource block corresponding to it.

[0050] It can be understood that the PSFCH to be transmitted is the PSFCH that the UE is about to transmit, that is, one of the UEs needs to send information to the target UE, and the relevant content information is carried on the PSFCH. And when one of the UEs transmits the PSFCH to the target UE, multiple PSFCHs can be transmitted at one time.

[0051] It is worth noting that when the UE transmits signals on dedicated PRBs and shared interleaved RBs, if the dedicated PRBs and shared interleaved RBs are located in a bandwidth of 1 MHz, the shared interleaved RBs may be lost due to PSD limitations. Therefore, in an RB set, the shared interleaved RBs are likely to transmit only a part of the RBs.

[0052] It is worth noting that when PSFCH is transmitted in the SL-U system, the shared interleaved RB is configured based on the resource pool. The number of shared interleaved RBs on each Rb set is 10 or 11 PRBs at equal intervals. The dedicated PRBs of PSFCH use part or all of the PRBs in the RBset except the shared interleaved RBs. According to the system configuration, a PSFCH transmission is located in an RB set, occupying K3 dedicated PRBs and several shared interleaved RBs in the RB set. When the dedicated PRBs and shared interleaved RBs are within 1 MHz, if the OCB requirements are not affected, the shared PRBs are often discarded without transmitting power.

[0053] Step S120: Determine the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted and the number N1 of shared interleaved resource blocks corresponding to the PSFCHs to be transmitted.

[0054] In an embodiment of the present application, for the PSFCH to be transmitted, it is necessary to determine the number of PSFCHs to be transmitted, and then the transmission power of each PSFCH can be determined according to the number of PSFCHs to be transmitted and the number of shared interleaved resource blocks N1 corresponding to the PSFCHs to be transmitted. Among them, when determining the PSFCH transmission power, it is mainly based on the number of PSFCHs to be transmitted and the number of shared interleaved resource blocks N1 corresponding to the PSFCHs to be transmitted; the number of PSFCHs to be transmitted or the number of shared interleaved resource blocks N1 will make the transmission power of the PSFCH to be transmitted different. In addition, the transmission power of the PSFCH to be transmitted not only needs to meet the OCB requirements, but also cannot be greater than the maximum transmission power that the UE can generate, and the number of PSFCHs actually transmitted by each UE at a PSFCH feedback opportunity cannot exceed the maximum PSFCH transmission number of the UE.

[0055] See also Figure 8 The number of PSFCHs to be transmitted can be obtained by specifically including the following steps S111 to S113:

[0056] Step S111, obtaining the number of PSFCHs scheduled by the user equipment;

[0057] Step S112, when the number of PSFCHs scheduled by the user equipment is less than or equal to the maximum number of PSFCHs transmitted by the user equipment, determining that the number of PSFCHs to be transmitted is equal to the number of PSFCHs scheduled by the user equipment;

[0058] Step S113, when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs for transmission of the user equipment, determine the PSFCH to be transmitted according to the PSFCH transmission priority and / or the PSFCH transmission content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment.

[0059] In an embodiment of the present application, in the process of determining the number of PSFCHs to be transmitted, the number of PSFCHs scheduled for the user equipment is first obtained; then, when the number of PSFCHs scheduled for the user equipment is less than or equal to the maximum number of PSFCHs for transmission of the user equipment, it is determined that the number of PSFCHs to be transmitted is equal to the number of PSFCHs scheduled for the user equipment; when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs for transmission of the user equipment, the PSFCHs to be transmitted are determined according to the PSFCH transmission priority and / or the PSFCH transmission content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment.

[0060] In a possible exemplary embodiment, the number of PSFCHs scheduled by the user equipment is 4, and the maximum number of PSFCHs for transmission of the user equipment is 5, and the PSFCHs scheduled by the four user equipments are all used as PSFCHs to be transmitted. The maximum number of PSFCHs for transmission may be preset, and the maximum number of PSFCHs for transmission may be set according to the performance of the user equipment; for different user equipments, the maximum number of PSFCHs for transmission may be different.

[0061] In a possible exemplary embodiment, the number of PSFCHs scheduled by the user equipment is 7, and the maximum number of PSFCHs transmitted by the user equipment is 5. At this time, the number of PSFCHs scheduled by the user equipment is greater than the maximum number of PSFCHs transmitted by the user equipment, and the 7 scheduled PSFCHs need to be selected and processed. The selection can be performed according to the priority of each PSFCH, and the 2 PSFCHs with the lowest priority are discarded, and the other 5 PSFCHs with relatively higher priorities are used as PSFCHs to be transmitted; or, in the process of selecting the 7 scheduled PSFCHs, the selection can also be performed according to the transmission information content of each PSFCH. For example, 2 PSFCHs transmit indicative information of low importance, while the other 5 PSFCHs transmit substantive conversation information of high importance. Therefore, the 2 PSFCHs transmitting indicative information of low importance can be discarded, and the 5 PSFCHs transmitting substantive conversation information of relatively high importance can be used as PSFCHs to be transmitted. Among them, when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs for transmission of the user equipment, the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment, which can greatly improve the data transmission efficiency between user equipment.

[0062] In an embodiment of the present application, in the process of selecting the scheduled PSFCH, it can be based on only one of the PSFCH transmission priority and the PSFCH transmission information content, or it can be comprehensively determined based on the two. For example, the priority and the importance of the content can be uniformly weighted. For example, the highest transmission priority can be assigned a weight of 5, the secondary transmission priority can be assigned a weight of 3, and the lowest transmission priority can be assigned a weight of 1; the most important content can be assigned a weight of 4, the secondary content can be assigned a weight of 2, and the less important content can be assigned a weight of 1; therefore, in the subsequent process of PSFCH selection, the PSFCH can be weighted, for example, for a PSFCH with the highest transmission priority and the most important transmission content, a weight of 9 will be assigned; for a PSFCH with a secondary transmission priority and the transmission content is less important, a weight of 4 will be assigned; the scheduled PSFCHs are weighted separately, and finally the PSFCH is selected according to the size of the weight, thereby improving the pertinence and reliability of data transmission.

[0063] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted may specifically include the following steps S121-S122:

[0064] Step S121: according to the maximum transmit power P of the user equipment CMAX, the number of PSFCHs to be transmitted, the number of dedicated resource blocks K3 contained in the PSFCH to be transmitted, and the number of shared interleaved resource blocks N1 corresponding to the PSFCH to be transmitted, and determine the resource block reference transmit power P oneRB , the transmit power of a dedicated resource block or a shared interleaved resource block is equal to the resource block reference transmit power P oneRB ;

[0065] Step S122: according to the resource block reference transmit power P oneRB and the number of dedicated resource blocks K3, determine the transmit power of the PSFCH to be transmitted.

[0066] In the embodiment of the present application, in the process of determining the transmit power of each PSFCH to be transmitted, firstly, according to the maximum transmit power P of the user equipment, CMAX , the number of PSFCHs to be transmitted, the number of dedicated resource blocks K3 contained in the PSFCH to be transmitted, and the number of shared interleaved resource blocks N1 corresponding to the PSFCH to be transmitted, and determine the resource block reference transmit power P oneRB , the transmit power of a dedicated resource block or a shared interleaved resource block is equal to the resource block reference transmit power P oneRB ; Finally, according to the resource block reference transmit power P oneRB and the number of dedicated resource blocks K3, determine the transmit power of the PSFCH to be transmitted.

[0067] It is worth noting that the maximum transmit power of the user equipment P CMAX It is related to the performance of the user equipment itself. The maximum transmit power P of different user equipment CMAX May vary.

[0068] In a possible exemplary embodiment, when power control is not enabled, the UE is scheduled for a total of N sch,Tx,PSFCH PSFCH transmission, according to the UE's maximum PSFCH transmission number capability, PSFCH transmission priority, PSFCH transmission information content to determine N Tx,PSFCH PSFCH transmissions, further, according to N Tx,PSFCH The resource location of each PSFCH transmission determines the number N1 of shared interleaved RBs, and at this time, the transmit power of each PSFCH transmission and the transmit power on the remaining shared interleaved RBs are further determined.

[0069] When the per RB transmit power on the shared interleaved RB is equal to the per RB power on the dedicated PRB, the number of PSFCH transmissions N is Tx,PSFCH , and the number of PRBs N1 of shared interleaved RBs, determine the transmit power P on each PRB oneRB =P CMAX -10log 10 (NTx,PSFCH *K3+N1)[dBm], where P oneRB That is, the resource block reference transmission power P mentioned in the above embodiment oneRB , K3 represents the number of dedicated resource blocks; then the transmit power of PSFCH transmission is P PSFCH,k (i) = P oneRB +10log 10 (K3)[dBm]; the transmit power on one RB in the shared interlace is P oneRB [dBm].

[0070] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted may specifically include the following steps S123 to S125:

[0071] Step S123, obtaining a configured power offset value X, wherein the configured power offset value X indicates that the transmit power of the dedicated resource block is X dB higher than the transmit power of the shared interleaved resource block;
