Abstract
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 the listen before talk (LBT) bandwidth of about 20M as the frequency domain unit, and a physical sidelink feedback channel (PSFCH) of SL-U is located within an LBT bandwidth in the transmission frequency domain. 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 adopts a dedicated interleaving form, and the device occupies all physical resource blocks (PRBs) on one interleaving in the resource block set (RB set) at a time when transmitting PSFCH feedback; however, the interleaving in the RB set may be 10 PRBs or 11 PRBs. When performing power control, it may be necessary to ensure that the power of each PSFCH transmission is equal. Therefore, in the area with OCB requirements in the unlicensed frequency band, considering the OCB requirements and the power spectral density (PSD) restrictions, how to determine the PSFCH transmission power is an unresolved problem. Summary of the invention
[0003] The embodiments of the present application provide a power determination method, a user device, and a computer-readable storage medium, which are intended to determine the transmission power of each PSFCH transmission when the user device schedules multiple PSFCH feedback transmissions while satisfying the maximum number of PSFCH transmissions of the user device, the maximum transmission power of the device, and the channel occupancy requirements.

[0011] In the embodiment of the present application, in the process of determining the transmit power of the PSFCH, the number of PSFCH transmissions to be transmitted at the PSFCH transmission opportunity is first determined; then the transmit power of each PSFCH to be transmitted can be determined based on the number of PSFCHs to be transmitted. Through the scheme of the embodiment of the present application, when the user equipment schedules multiple PSFCH feedback transmissions, the transmit power of each PSFCH transmission can be determined while meeting the maximum number of PSFCH transmissions of the user equipment, the maximum transmit power of the equipment, and the channel occupancy requirements.

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

[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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).
[0033] 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, useful information is directly carried on a dedicated interleaved RB on the RB set, and the dedicated interleaved RB resource locations of different UEs may be different.
[0034] 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 one RB set; under the SCS of 30kHz, there are 5 interleavings on each RB set. PSFCH appears in the SL communication resource pool according to a certain period in the time domain. 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 transmission power of the device 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 embodiment of the present application mainly explains the method for determining power and resources using a dedicated interleaving format for PSFCH.
[0035] See also Figure 5 In the SL resource pool, the PSFCH resources in the time domain appear periodically; in the frequency domain, for each RB set, the interleaving of the PSFCH time domain symbols on the RB set can be mapped to a subband (subchannel) of a time slot on the same RB set in the past according to a certain mapping rule. Figure 5 In the example, the PSFCH period is a time slot in two resource pools. Assuming that an RB set contains two subchannels, each subchannel in each time slot can be uniquely mapped to a set of feedback resources according to certain rules. The set of feedback resources includes m resources. A PSFCH feedback resource can be considered as an interlace on the RB set, which means that some PSFCHs contain 10 PRBs and some PSFCHs contain 11 PRBs.
[0036] It should be noted that the signaling or parameters of the SL-U in the embodiment of the present application may be obtained through configuration, or pre-configured, or predetermined to be obtained, which are collectively referred to as configuration in the text without limiting the distinction; the configuration in the embodiment of the present application may include a network configuring a device, a device configuring another device, or pre-configuration. It is worth noting that, regardless of whether it is a PSFCH transmission containing 10 PRBs or a PSFCH transmission containing 11 PRBs, the transmission power between the PRBs actually transmitted within a PSFCH transmission is equal.
[0037] 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 does not exceed the configured UE maximum transmission power; When the UE transmits PSFCH on a dedicated PRB on an RB set, it may be necessary to transmit signals on a configured or pre-configured shared interleaved RB at the same time in order to meet OCB requirements.
[0038] In order to solve the problem of how to determine the PSFCH transmission power in an area with OCB requirements in an unlicensed frequency band, taking into account the OCB requirements and the power spectrum density (PSD) restrictions, the embodiment of the present application provides a power determination method, a user device and a computer-readable storage medium. In the embodiment of the present application, in the process of determining the transmission power of the PSFCH, the number of PSFCH transmissions to be transmitted at the PSFCH transmission opportunity is first determined; then, the transmission power of each PSFCH to be transmitted can be determined according to the number of PSFCHs to be transmitted. Through the scheme of the embodiment of the present application, when the user equipment schedules multiple PSFCH feedback transmissions, the transmission power of each PSFCH transmission can be determined while meeting the maximum number of PSFCH transmissions of the user equipment, the maximum transmission power of the equipment and the channel occupancy requirements.

The present application can also be practiced in distributed computing environments, in which tasks are performed by remote processing devices connected through 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 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.

[0043] 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.
[0044] See also Figure 6 , Figure 6 Schematic diagram of the steps of a power determination method provided in an embodiment of the present application. Figure 6 As shown, the power determination method includes the following steps S110 to S120, and each step is introduced in turn below:
[0045] Step S110, determining the number of PSFCH transmissions to be transmitted at the physical side link feedback channel PSFCH transmission opportunity.
[0046] In an embodiment of the present application, in the process of determining power, it is first necessary to determine the number of PSFCH transmissions to be transmitted at the PSFCH transmission opportunity; the PSFCH transmission opportunity referred to in the embodiment of the present application is the opportunity when one user terminal is about to send a PSFCH to be transmitted to another user terminal, wherein the number of PSFCH transmissions to be transmitted may be multiple, and in the process of determining power in the embodiment of the present application, it is based on the PSFCH transmission in the form of dedicated interleaving, and when the device transmits PSFCH feedback, it occupies all dedicated resource blocks on one interleaving in the resource group at a time.
[0047] In an embodiment of the present application, the number of dedicated resource blocks carried by each PSFCH in a resource group is not fixed. For example, there may be 10 or 11 dedicated resource blocks in a resource group; 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.
[0048] 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.
[0049] Step S120: determining the transmission power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted.
[0050] In an embodiment of the present application, for the PSFCH to be transmitted, it is necessary to determine the number of each PSFCH to be transmitted, and then the transmit power of the PSFCH can be calculated and determined according to the different numbers of PSFCH to be transmitted. Among them, when determining the PSFCH transmit power, it is mainly based on the number of PSFCHs to be transmitted; the difference in the number of PSFCHs to be transmitted will make the actual transmit power of the PSFCH to be transmitted different. The actual transmit power of the PSFCH to be transmitted must not only meet the OCB requirements, but also cannot be greater than the maximum transmit 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.
[0051] See also Figure 7 , Figure 7 yes Figure 6 A schematic diagram of sub-steps of step S110 in FIG. Figure 7 This is a schematic diagram of the steps for determining each PSFCH to be transmitted provided by an embodiment of the present application. Specifically, the following steps S111 to S113 may be included:
[0052] Step S111, obtaining the PSFCH scheduled by the user equipment;
[0053] 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, all PSFCHs scheduled by the user equipment are used as PSFCHs to be transmitted;
[0054] Step S113, when the number of PSFCHs scheduled by the user equipment is greater than the maximum number of PSFCHs for transmission of the user equipment, select the PSFCH to be transmitted from the PSFCHs scheduled by the user equipment according to at least one of the PSFCH transmission priority and the PSFCH transmission information content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment.
[0055] In an embodiment of the present application, in the process of determining each PSFCH to be transmitted, the PSFCH that needs to be scheduled of the user equipment that is ready to perform PSFCH transmission is first obtained; then the number of scheduled PSFCHs is determined; 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, all PSFCHs scheduled for the user equipment will be used as PSFCHs to be transmitted; 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 PSFCH to be transmitted is selected from the PSFCHs scheduled for the user equipment based on at least one of the PSFCH transmission priority and the PSFCH transmission information content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment, so as to achieve the maximum possible data transmission and improve the efficiency of data transmission.
[0056] 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.
[0057] 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.
[0058] 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.
[0059] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted may include the following steps S121:
[0060] Step S121: according to the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipmentCMAX , determine the transmit power of each PSFCH to be transmitted, and the transmit power of each PSFCH to be transmitted is equal.
[0061] In the embodiment of the present application, since the transmit power of each PSFCH to be transmitted is equal, the actual transmit power of each PSFCH to be transmitted can be determined according to the number of PSFCHs to be transmitted and the maximum transmit power of the user equipment. The maximum transmit power of the user equipment can be determined according to the device performance of the user equipment, and the maximum transmit power of different user equipment may also be different.
[0062] In some embodiments of the present application, the PSFCH to be transmitted includes a first type PSFCH and / or a second type PSFCH, wherein the number of PRBs included in the first type PSFCH is K1, and the number of PRBs included in the second type PSFCH is K2, K1 is less than K2, and K1 and K2 are both positive integers; determining the PRB transmit power may include but is not limited to steps S131-step S132:
[0063] Step S131, for the first type of PSFCH, the transmit power of the PSFCH to be transmitted is used for K1 PRBs included in the first type of PSFCH and the transmit power of each PRB is determined according to the value of K1;
[0064] Step S132, for the second type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K2, or, the transmission power of the PSFCH to be transmitted is used for K1 PRBs selected from the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K1.
[0065] In an embodiment of the present application, the PSFCH to be transmitted may include a first type of PSFCH and / or a second type of PSFCH, wherein the number of PRBs included in the first type of PSFCH is K1, and the number of PRBs included in the second type of PSFCH is K2, K1 is less than K2, and exemplarily, K1 can be 10, and K2 can be 11; and for the first type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K1 PRBs included in the first type of PSFCH and the transmission power of each PRB is determined according to the value of K1; and for the second type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K2, or, the transmission power of the PSFCH to be transmitted is used for K1 PRBs selected from the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K1.
[0066] In a possible exemplary embodiment, the first type of PSFCH includes 10 PRBs, and the second type of PSFCH includes 11 PRBs; for the first type of PSFCH, the transmission power of the first type of PSFCH is used for the 10 PRBs included and the transmission power of each PRB is determined by the value 10; for the second type of PSFCH, the transmission power of the second type of PSFCH is used for the 11 PRBs included and the transmission power of each PRB is determined by the value 11, or 10 PRBs are selected from the 11 PRBs, and the transmission power of each PRB is determined by the value 10.
[0067] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted may include the following steps S122-S123:
[0068] Step S122, determining the total number N of PRBs included in all PSFCHs to be transmitted and determining the transmit power on each PRB according to the total number N of PRBs;
[0069] Step S123, for each PSFCH to be transmitted, determine the transmission power of the PSFCH to be transmitted according to the transmission power on each PRB and the number of PRBs contained in the PSFCH to be transmitted, the transmission power of the PSFCH to be transmitted is the sum of the transmission powers on all PRBs included in the PSFCH to be transmitted, wherein the number of PRBs contained in each PSFCH to be transmitted is K1 or K2, K1 is less than K2, and K1 and K2 are both positive integers.
[0070] In an embodiment of the present application, in the process of determining the transmission power of each PSFCH to be transmitted, the total number N of PRBs contained in all PSFCHs to be transmitted can also be determined, and the transmission power on each PRB can be determined based on the total number N of PRBs; wherein the transmission power of the PSFCH to be transmitted is the sum of the transmission powers of all PRBs included in the PSFCH to be transmitted, wherein the number of PRBs contained in each PSFCH to be transmitted is K1 or K2, K1 is less than K2, and K1 and K2 are both positive integers.
[0071] In a possible exemplary embodiment, there are a total of 3 PSFCHs to be transmitted, including 1 first-class PSFCH and 2 second-class PSFCHs. At this time, the 3 PSFCHs contain a total of 32 PRBs; the transmission power of the first-class PSFCH can be determined based on the total number 32 and the number of PRBs it contains, which is 10; the transmission power of the second-class PSFCH can be determined based on the total number 32 and the number of PRBs it contains, which is 11.
[0072] In a possible exemplary embodiment, when power control is not enabled, the user equipment is scheduled for a total of N sch,Tx,PSFCHPSFCH 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 determine the transmit power of each PSFCH transmission. Since the power of PSFCH transmissions containing different numbers of PRBs can be equal or unequal, the per RB power density between different PSFCH transmissions can also be equal or unequal; for different situations, different calculation methods can be used to calculate the power. The specific method can be as follows:
[0073] When the power of PSFCH transmissions with different PRB numbers is equal and the per RB power density between different PSFCH transmissions is unequal, in the process of determining each PSFCH to be transmitted, the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipment are used as the basis. CMAX The actual transmit power of each PSFCH can be determined, and the calculation formula can be as follows:
[0074] P PSFCH,k (i) = P CMAX -10log 10 (N Tx,PSFCH )[dBm]
