[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 27, 2023, with application number 202311287637.9 and invention name “Power determination method, user equipment and storage medium”. The entire contents of the Chinese patent application are incorporated herein by reference. Technical Field

[0003] 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

[0004] In related technologies, there are two air interface technologies for SideLink (SL) communications: 4G Long Term Evolution (LTE) and 5G New Radio (NR). In the future, SL communications may utilize the sixth-generation mobile communication technology (6G). SL can operate in unlicensed frequency bands, known as SideLink Unlicensed (SL-U). Unlicensed frequency bands are measured in approximately 20 MHz of listen before talk (LBT) bandwidth. A physical sidelink feedback channel (PSFCH) in an SL-U is transmitted within an LBT bandwidth. When 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 uses shared interleaved resource blocks (RBs) combined with dedicated RBs. 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 opportunity. 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) constraints, how to determine the number of PSFCH transmission resources and power to ensure that the number of simultaneously transmitted PSFCH transmissions does not exceed the device's maximum transmit power or the device's maximum number of PSFCH transmissions is an unresolved problem.

[0028] 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 technologies is first given.

[0029] As shown in Figure 1, in a SideLink (SL) communication system, when user equipment (UE) needs to transmit services, the service data between the UEs does not pass through the network side, that is, it is not forwarded through the cellular link between the UE and the base station. Instead, it is directly transmitted from the source UE to the target UE via the SL. This approach can reduce the burden on the cellular network, reduce the battery power consumption of user equipment, and improve the robustness of the network infrastructure, effectively meeting the requirements of high-data-rate services and proximity services. It also supports direct communication in scenarios without network coverage, which can meet special communication needs such as public safety. In this case, the devices operate on resources defined by the communication resource pool.

[0030] As shown in Figure 2, multiple nominal channel bandwidths are defined in the unlicensed spectrum, each with a bandwidth of 20 MHz. When operating in the unlicensed spectrum, a device must listen on the defined nominal channel bandwidth and transmit only when the channel is idle. The nominal channel bandwidth can be divided based on the frequency domain. For example, a segment of unlicensed spectrum can be divided into 20 MHz bands, resulting in multiple nominal channel bandwidths.

[0031] 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 unlicensed 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 designed the frequency domain structure 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).

[0032] The SL-U channel structure definition proposes a resource block set (RB set) channel structure. This resource block set is similar to the nominal bandwidth defined in the unlicensed mode, approximately 20M. Similarly, the OCB requirement must also be met within the RB set. Two frequency domain formats are defined for the PSFCH feedback channel within the RB set, as shown in Figures 3 and 4. Figure 3 shows the format of a shared interleaved resource block (RB) and one dedicated physical resource block (PRB); Figure 4 shows the format of a dedicated interleaved RB for PSFCH. Furthermore, in the format shown in Figure 3, when a device transmits a PSFCH within the current RB set, it must transmit signals on both shared interleaved RBs and dedicated PRBs. Transmitting signals on shared interleaved PRBs primarily meets the OCB requirement, while transmitting signals on dedicated PRBs carries the useful information required by the PSFCH. The shared interleaved PRBs are located in the same RB set for all devices, while the dedicated PRBs may be located in different locations. In the format shown in Figure 4, when a device transmits a PSFCH within the current RB set, the useful information is directly carried on a dedicated interleaved RB in the RB set. The location of the dedicated interleaved RB resource for different UEs may be different. It is worth noting that the embodiment of the present application mainly determines the power under the channel structure shown in Figure 3.

[0033] It should be noted that the interleaving on the RB set is 11 or 10 PRBs with equal spacing in the RB set; under a 15kHz subcarrier spacing (SCS), there are 10 interleavings on an RB set; under a 30kHz SCS, there are 5 interleavings on each RB set. In the time domain, PSFCH appears on the SL communication resource pool according to a certain period. A PSFCH time domain opportunity is often associated with multiple past SL data transmissions. 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 transmit power is limited, when the device transmits PSFCH, if the number of scheduled PSFCH transmissions or the device's transmit 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 formats of PSFCH shared interleaved RBs and dedicated PRBs.

[0034] Please refer to Figure 5. For the PSFCH format of shared interleaved RBs and K3 dedicated PRBs, the shared interleaved RBs occupy one interleaved area within the RB set. All UEs can transmit signals on this shared interleaved area to meet the OCB requirements on the RB set. The K3 dedicated PRBs are located on another interleaved area, and the dedicated PRBs between UEs are generally considered to be orthogonal. The value of K3 is configurable, and it is generally considered that K3 can be 1, 2, 5, etc. As shown in Figure 5, when K3 is equal to 2, UE1's PSFCH transmission and UE2's PSFCH transmission. As shown in Figure 5, when UE1 transmits PSFCH on the RB set, it sends signals on 10 equally spaced shared interleaved PRBs and 2 UE1 dedicated PRBs. When UE2 transmits PSFCH on the RB set, it sends signals on 10 equally spaced shared interleaved PRBs and 2 UE2 dedicated PRBs.

[0035] 6 , UE1 can also transmit one PSFCH on two RB sets. For each RB set, UE1 sends signals on 10 equally spaced shared interleaved RBs and two UE1-dedicated PRBs.

[0036] 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 device, or pre-configuration.

[0037] For PSFCH transmission on SL, downlink power control may be enabled or not, which is determined by the configuration or pre-configured 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 No more than the maximum number of PSFCH transmissions N of the UE max,PSFCH The actual transmission power of the UE during the PSFCH feedback opportunity (considering the total power of shared interleaved RBs and dedicated PRBs) does not exceed the configured maximum transmission power of the UE. When the UE transmits a PSFCH on a dedicated PRB in an RB set, it may also need to transmit on a configured or pre-configured shared interleaved RB to meet the OCB requirement. It is worth noting that the pre-configuration in this application may include pre-definition, configuration, and pre-configuration.

[0038] In order to solve the problem that the user equipment may send multiple PSFCHs at the same time during the PSFCH feedback period, these PSFCHs have different priorities and may be located in the same or different LBT bandwidths. Therefore, in the area with OCB requirements in the unlicensed frequency band, the OCB requirements and the power spectrum density (PSD) are considered to determine the number of resources and power for PSFCH transmission to ensure that the number of PSFCH transmissions transmitted simultaneously does not exceed the maximum transmit 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 shared interleaved resource blocks and dedicated resource blocks; according to the number of PSFCHs to be transmitted and the number N1 of shared interleaved resource blocks 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.

[0039] The power determination method of the embodiments of the present application may be executed by a terminal device. The terminal device may also be a smartphone, desktop computer, tablet computer, laptop computer, smart TV, smart voice interaction device, smart home appliance, or other terminal devices such as smart transportation equipment, smart home equipment, robots, and drones.

[0040] 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. It can also be 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 (CDNs), 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, and the like. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, and the like that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments in which tasks are performed by remote processing devices connected via a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media, including storage devices.

[0042] It should be noted that in each embodiment 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 such data will comply with relevant laws, regulations and standards.

[0043] The power determination method, user equipment, and computer-readable storage medium provided in the embodiments of the present application are illustrated through the following embodiments. First, the power determination method in the embodiments of the present application is described.

[0044] Please refer to Figure 7, which is a schematic diagram of the steps of a power determination method provided by an embodiment of the present application. As shown in Figure 7, the power determination method includes the following steps S110 to S120, and each step is introduced in sequence below.

[0045] 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.

[0046] 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. The power determination process in the embodiment of the present application is based on the use of shared interleaved resource blocks and dedicated resource block groups for PSFCH transmission.

[0047] 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 equipment, that is, the user equipment will only transmit data on the dedicated resource block corresponding to it.

[0048] It is 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.

[0049] 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 the 1 MHz bandwidth, the shared interleaved RBs may be lost due to PSD limitations. Therefore, within an RB set, the shared interleaved RBs are likely to transmit only a part of the RBs.

[0050] 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 RB set except the shared interleaved RBs. According to the system configuration, a PSFCH transmission is located within 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.

[0051] Step S120 : determining 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.

[0052] In an embodiment of the present application, for the PSFCHs that are ready 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 based on the number of PSFCHs to be transmitted and the number N1 of shared interleaved resource blocks 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 N1 of shared interleaved resource blocks corresponding to the PSFCHs to be transmitted; the difference in the number of PSFCHs to be transmitted or the number N1 of shared interleaved resource blocks will cause the transmission power of the PSFCHs to be transmitted to be 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.

[0053] Please refer to FIG. 8 . The number of PSFCHs to be transmitted can be obtained by including the following steps S111 to S113 .

[0054] Step S111: Acquire the number of PSFCHs scheduled by the user equipment.

[0055] Step S112: When the number of PSFCHs scheduled by the user equipment is less than or equal to the maximum number of PSFCHs to be transmitted by the user equipment, determine that the number of PSFCHs to be transmitted is equal to the number of PSFCHs scheduled by the user equipment.

[0056] Step S113: When the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs transmitted by the user equipment, the PSFCH to be transmitted is determined according to the PSFCH transmission priority and / or the PSFCH transmission content, where the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs transmitted by the user equipment.

[0057] 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, the number of PSFCHs to be transmitted is determined to be 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.

[0058] In one possible exemplary embodiment, if the number of PSFCHs scheduled for a user equipment is four and the maximum number of PSFCHs that the user equipment can transmit is five, all four PSFCHs scheduled for the user equipment are used as PSFCHs to be transmitted. The maximum number of PSFCHs that can be transmitted can be pre-set based on the performance of the user equipment; the maximum number of PSFCHs that can be transmitted can vary for different user equipment.

[0059] In a possible exemplary embodiment, the number of PSFCHs scheduled for 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 for the user equipment is greater than the maximum number of PSFCHs transmitted by the user equipment, and it is necessary to select and process the 7 scheduled PSFCHs. The selection can be performed based on the priority of each PSFCH, and the 2 PSFCHs with the lowest priority can be discarded, and the other 5 PSFCHs with relatively higher priorities can be used as PSFCHs to be transmitted; or, in the process of selecting the 7 scheduled PSFCHs, the selection can also be performed based on the information content transmitted by each PSFCH. For example, two PSFCHs transmit indicative information of low importance, while the other five PSFCHs transmit substantive conversation information of high importance. Therefore, the two PSFCHs transmitting indicative information of low importance can be discarded, while the five PSFCHs transmitting substantive conversation information of relatively high importance can be used as PSFCHs to be transmitted. In this case, when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs to be transmitted by the user equipment, the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs to be transmitted by the user equipment, which can greatly improve the data transmission efficiency between user equipment.

[0060] In an embodiment of the present application, in the process of selecting the scheduled PSFCH, it can be determined based on only one of the PSFCH transmission priority and the PSFCH transmission information content, or a comprehensive judgment can be made 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 less important transmission content, a weight of 4 will be assigned; the scheduled PSFCHs are weighted separately, and finally the PSFCH is selected based on the size of the weight, thereby improving the pertinence and reliability of data transmission.

[0061] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted may include the following steps S121-S122.

[0062] Step S121: Based on 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, to 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 .

[0063] Step S122: Based on 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.

[0064] In the embodiment of the present application, in the process of determining the transmit power of each PSFCH to be transmitted, first, 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, to 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.

[0065] 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.

[0066] 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 transmission, 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.

[0067] 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 (N Tx,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].

[0068] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted may include the following steps S123 to S125.

[0069] Step S123: Obtain a configured power offset value X, where 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.

[0070] Step S124: Based on the maximum transmit power P of the user equipment CMAX, the number of PSFCHs to be transmitted, the number of shared interleaved resource blocks N1 corresponding to the PSFCHs to be transmitted, the number of dedicated resource blocks K3 contained in the PSFCHs to be transmitted, and at least one of the configured power offset value X, to determine the resource block reference transmit power P oneRB , the transmit power of the shared interleaved resource block is equal to the resource block reference transmit power P oneRB ; Among them, the transmit power on the shared interleaved resource block is equal to the resource block reference transmit power P oneRB , or the transmit power on the shared interleaved resource block is based on the resource block reference transmit power P oneRB and configured power offset value X.

[0071] Step S125: Based on the resource block reference transmit power P oneRB , at least one of the number K3 of dedicated resource blocks included in the PSFCH to be transmitted and the configured power offset value X, to determine the transmit power of the PSFCH to be transmitted.
