Region classification for resource block allocation during power boosting of shaped transmissions

Abstract

This disclosure relates to techniques that facilitate power boosting for wireless communication devices (e.g., user equipment). The user equipment can be limited by a specification (e.g., a 3GPP specification) that requires a maximum power reduction (MPR) according to a resource block allocation region in which the user equipment operates. However, certain regions defined by the 3GPP specification can not facilitate transmission power boosting that is applied to shaped (e.g., modulated) transmissions. The techniques disclosed herein include defining the regions such that the MPR limit applied to an allocation of the user equipment for achieving power boosting is reduced or minimized. The regions can be defined using parameters based on a maximum number of resource blocks specified for a certain channel bandwidth, an amount of allocated resource blocks, and a resource block at which the allocation begins.

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Application No. 63 / 292,249, filed on December 21, 2021, entitled “REGIONAL CLASSIFICATION OF RESOURCE BLOCK ALLOCATION DURING POWER BOOST FOR SHAPED TRANSMISSION”, the entire contents of which are incorporated herein by reference for all purposes. Background Technology

[0003] This disclosure relates generally to wireless communication, and more specifically, to resource block allocation in wireless communication devices. A communication device can transmit signals at a power level based on the frequency region in which the communication device operates. Regions can be defined according to resource block allocation. However, certain region definitions may not facilitate increased transmit power, such as that applied to shaping (e.g., modulation) transmission. Summary of the Invention

[0004] The following outlines some of the embodiments disclosed herein. It should be understood that these aspects are presented merely to provide the reader with a concise overview of these particular embodiments, and are not intended to limit the scope of this disclosure. In fact, this disclosure may cover many aspects not set forth below.

[0005] In one embodiment, a user equipment includes: a receiver; a transmitter; and processing circuitry communicatively coupled to the receiver and the transmitter. The processing circuitry can receive, via the receiver, a first indication of resource block allocation from a base station, the resource block allocation corresponding to one or more of at least four resource block allocation regions, each of the at least four resource block allocation regions corresponding to a different maximum power reduction value. When operating in power-up mode, the processing circuitry can transmit signals via the transmitter based on the resource block allocation regions.

[0006] In another embodiment, the tangible, non-transitory computer-readable medium may include instructions that, when executed by one or more processors, cause the one or more processors to detect a first indication from a base station; synchronize with the base station; send a second indication of distance from the base station to the base station; receive from the base station via a receiver a third indication of resource block allocation for transmitting a signal, the resource block allocation corresponding to a resource block allocation area; reduce the transmitter's transmit power by a maximum power reduction value based on a spectral shaping filter, the resource block allocation, or both, thereby generating a reduced transmit power; and transmit a signal via the transmitter using the resource block allocation at the reduced transmit power.

[0007] In yet another embodiment, the method may include detecting a first indication of a base station; synchronizing with the base station; sending a second indication of distance from the base station to the base station; receiving from the base station a third indication of resource block allocation based on a plurality of resource block allocation regions and a fourth indication of a maximum power reduction value corresponding to the resource block allocation, based on the second indication of distance; and transmitting a signal at a power level based on the fourth indication of the maximum power reduction value.

Detailed Implementation

[0022] One or more specific implementations will be described below. To provide a brief description of these implementations, not all characteristics of the actual implementations are described in this specification. It should be understood that in the development of any such actual implementation, as in any engineering or design project, decisions must be made specific to many implementations to achieve the developer's specific objectives, such as compliance with system-related and business-related constraints that may vary from one implementation to another. Furthermore, it should be understood that such development work can be complex and time-consuming, but will still be routine work of design, fabrication, and manufacturing for those skilled in the art who benefit from this disclosure.

[0023] When describing elements of various embodiments of this disclosure, the articles “an” and “the” are intended to refer to one or more of the elements present. The terms “comprising,” “including,” and “having” are intended to be included and to indicate the presence of additional elements besides those listed. Additionally, it should be understood that reference to “an embodiment” or “an embodiment” of this disclosure is not intended to be construed as excluding the existence of additional embodiments also incorporating the cited features. Furthermore, specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. The use of the terms “generally,” “nearly,” “about,” and / or “substantially” should be understood to mean including close to the target (e.g., design, value, quantity), such as within limits of any suitable or conceivable error (e.g., within 0.1% of the target, within 1% of the target, within 5% of the target, within 10% of the target, within 25% of the target, etc.).

[0024] This disclosure relates to the allocation of resource blocks for wireless communication equipment (e.g., user equipment). Cellular networks may allocate frequency ranges (e.g., frequency channels or bands) for user equipment to transmit signals. When transmitting signals, user equipment may generate radio frequency signals outside the allocated channels (e.g., transmit). To avoid or reduce such out-of-channel (or out-of-band) transmissions, non-governmental (e.g., 3GPP) or governmental (e.g., the U.S. Federal Communications Commission) regulatory agencies may provide specifications or regulations that limit the maximum transmit power output. To comply with specifications and / or regulations, user equipment may reduce the output power of the transmitted signal. This power reduction may be referred to as the maximum power reduction (MPR). In practice, the MPR may be the amount of transmit power reduction that user equipment backs off and may be applied in multiple and / or incremental steps.

[0025] Resource block allocation determines the location or "area" (e.g., frequency range) for user equipment to transmit. The transmission area can be a function of resource block allocation, which includes the number of resource blocks allocated for transmission (referred to as the length of a contiguous resource block or LCRB) and the resource block at the start of the allocation (referred to as RB_start). Resource blocks can be defined by 3GPP specifications, and therefore the frequency width of a resource block can be 180 kHz, with a time length of one timeslot. As an example, a network can allocate resource block areas 3 to 10 (i.e., LCRB = 8; RB_start = 3). As another example, a network can allocate resource block areas 35 to 50 (i.e., LCRB = 16; RB_start = 35). Therefore, variations in the LCRB value and RB_start can determine the area of ​​signal transmission (e.g., the resource block allocation area).

[0026] Each region can be characterized by an MPR value. That is, each region can correspond to the amount by which the maximum transmit power can be reduced to comply with regulatory specifications or regulations. For example, the 3GPP specification defines three different resource block allocation regions: internal regions, external regions, and edge regions. Some regions (e.g., internal regions) may be closer to the center of the frequency channel and therefore may achieve greater power output (e.g., may require a lower MPR: 3 dB), while other regions (e.g., external or edge regions) may be closer to the edge of the frequency channel and therefore may be characterized by stricter power output limits (e.g., may require a higher MPR: 10 dB). However, regions defined by specifications and / or regulations (e.g., 3GPP specifications) may not be suitable for enhanced transmit power patterns, such as "power boost."

[0027] Specifically, spectral shaping is a technique that typically shapes a transmitted signal by applying one or more filters. The modulated waveform (e.g., by...) Spectral shaping of the waveform modulated by a binary phase-shift keying (BPSK) shaped filter reduces the peak-to-average power ratio (PAPR) and can enable power boosts (e.g., up to the transmitter's maximum output power) exceeding the nominal power of a certain power class. However, the power boost gain may depend on or be limited by resource block allocation (e.g., LCRB and RB_start values). It can be observed that resource block allocation regions that facilitate high power boosts (e.g., achieving greater transmit power output) overlap with 3GPP regions that require larger MPR constraints (e.g., outer and edge regions as defined by 3GPP specifications), except for regions with smaller MPR constraints (e.g., inner regions as defined by 3GPP specifications).

[0028] The overlap between allocations enabling power boosts and regions with larger MPR constraints illustrates locations where transmit power could be increased without significant out-of-channel transmission, but is not feasible due to current 3GPP specifications (e.g., Release 17). For example, a user equipment (UE) might have a nominal power output capability of 23 dB, which could be boosted to 29 dB, and when operating in certain resource block allocations, the UE might operate with a lower MPR constraint of 1 dB without significant out-of-channel transmission. However, if a resource block allocation enabling power boosts overlaps with an outer region of the 3GPP specification, and that outer region has an MPR constraint of 10 dB, then when the MPR is applied, the UE might be limited to a maximum power output of 19 dB (unlike 28 dB); the maximum power output is less than the nominal power output. Therefore, defining regions can be advantageous to enable power boosts across resource block allocations, thereby facilitating power boosts without applying excessive MPR constraints as defined under the 3GPP specification.

[0029] The implementations described herein provide various techniques to facilitate power enhancements for wireless communication devices (e.g., user equipment) by defining more precise regions for MPR applications. This can enable user equipment to achieve greater transmit power without significant out-of-channel emissions. These regions can be independent of channel bandwidth and subcarrier spacing and can be determined using a number of resource blocks (N) specified for a given channel bandwidth. RB The parameters are defined by the number or length of consecutively allocated resource blocks (LCRB) and the identification of the resource block at the start of allocation (RB_start). In other words, once the parameters for a region are established, these parameters remain valid even if the channel bandwidth and / or subcarrier spacing changes.

Network interface 26 may include, for example, one or more interfaces for personal area networks (PANs) such as Ultra Wideband (UWB) or... Networks, local area networks (LANs), or wireless local area networks (WLANs) such as those employing a protocol from the IEEE 802.11x family of protocols (e.g., Networks and / or wide area networks (WANs) such as any standards related to the 3rd Generation Partnership Project (3GPP), including, for example, 3rd generation (3G) cellular networks, Universal Mobile Telecommunications System (UMTS), 4th generation (4G) cellular networks, Long Term Evolution (LTE) Cellular networks, Long Term Evolution License Assisted Access (LTE-LAA) cellular networks, 5G cellular networks and / or New Radio (NR) cellular networks, satellite networks, non-terrestrial networks, etc. Specifically, network interface 26 may include, for example, one or more interfaces for using the version 15 cellular communication standard of the 5G specification, which includes millimeter-wave (mmWave) frequency ranges (e.g., 24.25–300 GHz), and / or any other version of the cellular communication standard (e.g., version 16, version 17, any future version) that defines and / or implements frequency ranges for wireless communication.

Figure 1User equipment 10. Specifically, base station 304 may include a next-generation NodeB (gNodeB or gNB) base station and may provide 5G / New Radio (NR) coverage to user equipment 10 via wireless communication network 302. In some embodiments, base station 304 may include an evolved NodeB (eNodeB) base station and may provide 4G / LTE coverage to user equipment 10 via wireless communication network 302. Base station 304 may include Figure 1 and Figure 2 At least some of the components of the user equipment 10 shown include one or more processors 12, memory 14, storage device 16, transmitter 52, and receiver 54. It should be understood that while this disclosure may use 5G / NR as an exemplary specification, the embodiments disclosed herein are applicable to other suitable specifications (e.g., such as 4G / LTE specifications, Super 5G / NR specifications, etc.). Furthermore, network 302 may include any suitable number of base stations 304 (e.g., one or more base stations 304, four or more base stations 304, ten or more base stations 304, etc.).

[0041] Network 302 can schedule user equipment 10 to perform uplink transmissions by allocating resource blocks to user equipment 10. Resource block allocation can be defined as multiple different areas based on certain parameters of allocation (e.g., the number of resource blocks allocated to user equipment 10, the resource blocks at the start of allocation, etc.). Figure 4 This is a graph illustrating the resource block allocation regions defined by 3GPP. The graph represents the length of continuously allocated resource blocks (LCRB) 402 along the y-axis and the resource block at the start of allocation (RB_start) 404 along the x-axis. The maximum value on the y-axis can represent the total number of resource blocks (N) specified for a given channel bandwidth. RB 412. The inner region 406 may include resource block allocations closer to the center frequency of the channel, the edge region 410 may include resource block allocations closer to the edge of the channel (e.g., which defines frequencies or regions outside the channel), and the outer region 408 may include resource block allocations closer to (e.g., but not as close as edge region 410) the edge of the channel. The following... Figure 5 and Figure 6 This illustrates how a launch allocated using a specific resource block can fall into various regions (e.g., in...). Figure 4 (The area displayed in the 3GPP defined area).

[0042] These regions can be defined by management specifications or regulations. For example, an inner region 406 can be defined as a resource block allocation that includes RB_start 404 with the lowest potential starting point (RB_start, low) equal to max(1, floor(LCRB / 2)), where max() is a max function that returns the maximum value of all variables, and floor(x) is a floor function that returns the largest integer less than or equal to x. Furthermore, the inner region's RB_start 404 can have a minimum value equal to N. RB -RB_start, the maximum potential starting point of low-LCRB (RB_start, high), where RB_start, low ≤ RB_start ≤ RB_start, high and LCRB ≤ ceil(N) RB / 2), where ceil(x) is the ceiling function that returns the smallest integer greater than or equal to x. Edge region 410 can be defined as a resource block allocation that includes resource blocks allocated at the bottom edge and / or top edge of the channel, where the channel includes LCRB≤2. Outer region 408 can be defined as a resource block allocation that does not fall within inner region 406 or edge region 410.

[0043] Each of the inner region 406, outer region 408, and edge region 410 can be characterized by an MPR value. That is, each region can correspond to an amount of transmit power that can be reduced to comply with regulatory specifications or regulations (e.g., TS 38.101-1) for maximum transmit power. For example, inner region 406 can correspond to a smaller MPR limit (e.g., an MPR of 3 dB), outer region 408 can correspond to a larger MPR limit (e.g., 6 dB), and edge region 410 can correspond to an even larger MPR limit (e.g., 10 dB). This is likely because higher transmit power near out-of-channel frequencies (e.g., in edge region 410 and / or outer region 408) increases the likelihood of communication interference at out-of-channel frequencies. Similarly, frequencies closer to the center of the allocated channel (e.g., inner region 406) are less likely to experience communication interference at out-of-channel frequencies.

[0044] User equipment 10 may store (e.g., in memory 14 and / or storage device 16) an MPR lookup table, allowing user equipment 10 to determine the MPR to be applied to each resource block allocated from network 302. Network 302 may also store an MPR lookup table, allowing network 302 to allocate resource blocks based on power budget considerations affected by the MPR of user equipment 10. However, user equipment 10 may over-apply the MPR, resulting in compromised transmit quality, potentially requiring higher transmit power without compromising out-of-channel communication. For example, if user equipment 10 is operating within external area 408, when user equipment 10 is triggered (e.g., based on specific absorption rate (SAR) and / or maximum permissible exposure (MPE) standards and regulations) to perform a backoff, user equipment 10 may back off the transmit power by the full 10 dB MPR. However, while the 3GPP specification may require a full 10dB MPR, for any allocation falling within outer area 408, certain resource block allocations within outer area 408 may be able to transmit with a lower MPR limit (e.g., 5dB) without generating out-of-channel communication.

[0045] Figure 5 This is a diagram of the external area allocation 500 granted by network 302 for channel 501 with bandwidth 520. The external area allocation 500 may include an LCRB 522 value of 6 (e.g., LCRB 522 includes six resource blocks 504, 506, 508, 510, 512, and 514) and may include an RB start 524 value of 1 (e.g., the index of the first resource block of LCRB 522, i.e., resource block 504, is 1). For example, if the number of resource blocks N for channel 501... RB If 412 is 10 (e.g., so that resource block 518 has index: 9, resource block 516 has index: 8, and resource block 502 has index: 0), then the emission using outer region allocation 500 (where LCRB522 = 6 and RB_start 524 = 1) can fall into outer region 408, and therefore these emissions may be subject to the MPR limit corresponding to outer region 408.

[0046] Similarly, Figure 6 This is a diagram of an internal area allocation 600 granted by network 302 for channel 501 having bandwidth 520, according to an embodiment of this disclosure. The internal area allocation 600 may include an LCRB 602 value: 3 (e.g., LCRB 602 includes resource blocks 510, 512, and 514), and may include an RB_start 604 index: 4 (e.g., the index of the first resource block of LCRB 602, i.e., resource block 510, is 4). For example, if the number of resource blocks N... RBIf 412 is 10, then the emission using internal region allocation 600 (where LCRB 602 = 3 and RB_start 604 = 4) can fall into internal region 406, and therefore these emissions may be subject to the MPR limit corresponding to internal region 406.

[0047] Figure 5 The external allocation 500 shown is Figure 6 The internal allocation 600 shown is merely an example, and the LCRB 402 and RB_start 404 values ​​corresponding to the internal region 406, external region 408, and edge region 410 can vary according to management standards or prescribed definitions. Furthermore, the allocation corresponding to the internal region 406, external region 408, and edge region 410 can be determined based on the N value of the allocation channel 501. RB 412 and changes. N RB 412 can be any suitable number, such as 10, 20, 100, 1000, etc., depending on what is assigned by network 302.

[0048] For many reasons, applying certain management provisions and / or specifications related to MPR (e.g., TS 38.101-1) may be disadvantageous. For example, regarding... Figure 4 The application of MPR in each region defined by 3GPP may reduce or suppress the ability of User Equipment 10 to apply enhanced transmit output power (referred to herein as "power boost"). User Equipment 10 can apply shaping filters to form modulated waveforms (e.g., The modulated waveform is used to perform a power boost and increase the output power of the transmitter 52 of user equipment 10 to exceed the nominal power of a certain power class. However, the amount of power reduction (e.g., MPR) compared to the applied power boost can depend on the resource blocks (e.g., LCRB 402 value and RB_start 404 value) allocated from network 302 to user equipment 10.

[0049] Resource block allocations that promote power enhancement may overlap with currently 3GPP-defined regions (e.g., outer region 408 and / or edge region 410) that correspond to larger MPR limits, which may reduce or suppress the ability to provide higher transmit power. Figure 7 The following discussion will help to clarify Figure 4 The shortcomings of the area definition described in the text.

[0050] Figure 7 This is based on the implementation scheme of this disclosure to promote the enhancement of transmission power (regarding...). Figure 4 A diagram of resource block allocation areas (as discussed in the 3GPP-defined areas). Figure 7This can include regions characterized by low MPR (e.g., high power boost region 702) and regions characterized by higher MPR (e.g., low power boost regions 704 and 706). As previously described, applying power boost enables user equipment 10 to increase the output power of transmitter 52 beyond its nominal power. For example, user equipment 10 may be able to have a maximum power output of 23 dB in a standard (e.g., non-power boost) region. By applying power boost, user equipment 10 can alternatively transmit a signal at a maximum power output of 29 dB.

[0051] However, as Figure 7 As can be observed, power boost regions 702, 704, and 706 overlap with inner region 406, outer region 408, and edge region 410. Recalling the preceding discussion, inner region 406, outer region 408, and edge region 410 each correspond to different MPR constraints. Because a portion of high power boost region 702 overlaps with outer region 408 (which is subject to a higher MPR constraint), high power boost region 702 may not be effectively used or fully utilized in terms of transmit power. For example, if user equipment 10 receives a resource block allocation within high power boost region 702, user equipment 10 may be able to increase its maximum power output to 29 dB. However, if the allocation also falls within outer region 408, the 3GPP standard may require a 6 dB MPR. The 6 dB power boost achieved by high power boost region 702 may be offset by the 6 dB MPR required by the signal in outer region 408. Therefore, the resource block region definitions defined by 3GPP can reduce or suppress the power boost capability implemented by power boost regions 702, 704 and 706.

[0052] Figure 8 This is a grayscale chart set showing resource block allocation regions (e.g., 702, 704, and 706) that facilitate transmit power enhancement for different channel bandwidths according to embodiments of this disclosure. Figure 8 This includes simulations of the user equipment 10's maximum output power capability for a channel with a channel bandwidth of 20 MHz without impairing out-of-channel communication (e.g., 20MHz simulation 802), simulations of the user equipment 10's maximum output power capability for a channel with a channel bandwidth of 40 MHz without impairing out-of-channel communication (e.g., 40MHz simulation 804), and simulations of the user equipment 10's maximum output power capability for a channel with a channel bandwidth of 50 MHz without impairing out-of-channel communication (e.g., 50MHz simulation 804). z Simulation 806).

[0053] For each of the 20MHz simulation 802, 40MHz simulation 804, and 50MHz simulation 806, the darker portions 808 of the grayscale chart (e.g., high power boost region 702) represent regions with greater power boost capabilities, and the lighter portions 810 of the grayscale chart (e.g., low power boost regions 704 and 706) represent regions with lower power boost capabilities. The presence of high power boost regions 702 in the 20MHz simulation 802, 40MHz simulation 804, and 50MHz simulation 806 can be attributed to resource block allocation corresponding to high power boost regions 702 being closer to the center frequency of each channel (e.g., further away from the channel edges, thus less likely to result in out-of-channel transmission) and spectral shaping of the modulation waveform, as spectral shaping can reduce the peak-to-average power ratio (PAPR) and can achieve power boosts exceeding the nominal power of a certain power class (e.g., up to the maximum output power of the transmitter).

[0054] As can be observed, the high-power boost region 702 has a similar shape for each of the 20MHz simulation 802, 40MHz simulation 804, and 50MHz simulation 806 (e.g., the high-power boost region 702 corresponds to the same or similar allocation for each channel bandwidth). However, in the 50MHz simulation 806, certain features may become more clearly discernible. For example, the low-power boost region 706 is more pronounced in the 50MHz simulation 806 than it is in the 40MHz simulation 804 or the 30MHz simulation 802.

[0055] Figure 9 This illustrates different spectral shaping filters with BPSK modulation waveforms at different channel bandwidths, according to embodiments of the present disclosure. Resource block allocation area with increased transmit power

[0056] Grayscale charts (e.g., 702, 704, and 706). The available power boost for a single resource block allocation can often depend on the shaping filter applied to the resource block allocation. For some resource block allocations, applying a more aggressive filter can increase the amount of available power boost. As shown, the shaping filters applied to resource block allocations become increasingly aggressive. That is, the shaping filter applied to simulation 902 with coefficients [0.17 10.17] (e.g., where the first 0.17 indicates a front-end weighting of 0.17 for the waveform amplitude, 1 indicates a principal weight in the middle of the filter, and the second 0.17 indicates a rear-end weighting of 0.17 for the waveform amplitude) is the least aggressive, and the shaping filter with filter coefficients [0.4 10.4] is the most aggressive. As can be observed from 20MHz simulations 902, 906, and 910, the high power boost region 702 becomes larger because a more aggressive filter is applied. As can be observed from 50MHz simulations 904, 908, and 912, the more aggressive the filter, the larger the high-power boost region 702 becomes, and the more defined the low-power boost region 706 becomes.

[0057] It should be noted that applying certain filters, such as more aggressive shaping filters, may exclude certain resource block allocations. For example, applying aggressive filters in simulations 906 and 910 can reduce or completely eliminate the size of resource block allocations 918 and 920. Therefore, it may be more advantageous to utilize intermediate shaping filters (the shaping filter with coefficients [0.2810.28] applied in simulation 906) to clearly identify resource block allocations for which MPR can be reduced or optimized.

[0058] Based on the Figure 8 and Figure 9 The observed behavior in the allocation of resource blocks for channel bandwidth and shaping filters discussed earlier can identify different regions where the MPR can be adjusted more accurately. These regions can promote an increase or maximization of available power independent of channel bandwidth, subcarrier spacing, and shaping filter coefficients (e.g., a decrease or minimization of MPR). Considering this, Figure 10 This is a diagram of parameterized resource block allocation regions for enhancing transmit power according to embodiments of this disclosure. As shown in the figure, Figure 10 Six regions are depicted: region A1 1002, region A2 1004, region A3 1006, region A4 1008, region A5 1010, and region A6 1012.

[0059] Figure 10 The area depicted can be improved by identifying resource block allocations that enable user equipment 10 to achieve maximum output power without compromising out-of-channel communication, thereby increasing or maximizing available power (e.g., decreasing or minimizing MPR). Figure 7 As previously discussed regarding resource block allocations for achieving high power boost (e.g., corresponding to low MPR constraints), resource block allocations corresponding to areas defined in certain management specifications (e.g., 3GPP TS 38.101-1) may be incomplete and / or inaccurate. Therefore, some resource block allocations (e.g., those falling within outer region 408 and / or edge region 410) may be capable of achieving high power boost (e.g., low MPR), but are characterized by low power boost (e.g., high MPR) due to MPR constraints imposed by the management specifications. Consequently, under the management specifications, the power boost capability of user equipment 10 may be reduced or suppressed.

[0060] Regions with specified MPR limits can be defined to increase or maximize power gains (e.g., reduce or eliminate excessive MPR limits) without compromising out-of-channel transmission, while remaining independent of channel bandwidth and subcarrier spacing. That is, these regions may be applicable regardless of the applied channel bandwidth and subcarrier spacing (e.g., the regions may be fixed or remain unchanged when the channel bandwidth and / or subcarrier spacing changes). For example, regions A3 1006 and A1 1002 can achieve power gains (e.g., for a total maximum power output of 29 dB, the maximum power output increases by 6 dB). Region A3 1006 can be characterized by a 1 dB MPR limit, enabling user equipment 10 to transmit a signal with an output power of 28 dB in region A3 1006 after applying MPR. Region A1 1002 can be characterized by a 5 dB MPR limit, enabling user equipment 10 to transmit a signal with an output power of 24 dB in region A1 1002 after applying MPR. Therefore, by using… Figure 10 The area definition depicted can increase or maximize the available power boost (e.g., when compared to areas defined by the current 3GPP specification).

[0061] Network 302 can allocate resource blocks to User Equipment 10 based on transmit power considerations. Specifically, network 302 can allocate resource blocks to User Equipment 10 based on the distance between User Equipment 10 and base stations 304A and / or 304B. For example, if User Equipment 10 is near base station 304A, the network can allocate resource blocks to User Equipment 10 corresponding to a low power boost region (e.g., a region characterized by high MPR), because User Equipment 10 is near base station 304A, and therefore User Equipment 10 may be able to communicate with base station 304A using reduced transmit power. However, if User Equipment 10 is far from base station 304A (e.g., near the cell edge of base station 304A), the network can allocate resource blocks to User Equipment 10 corresponding to a high power boost region (e.g., a region characterized by low MPR), and User Equipment 10 can effectively communicate with base station 304A using a power boost transmit signal (e.g., by sending an enable signal or other indication of using a power boost mode).

[0062] User equipment 10 can receive and store (e.g., in memory 14 and / or storage device 16) updated MPR lookup tables (e.g., mapped to...). Figure 10 The network 302 can also store an MPR lookup table (depicting the area in the diagram) so that user equipment 10 can determine the amount of MPR required for each resource block allocation received by user equipment 10 from network 302. Network 302 can also store an updated MPR lookup table so that network 302 can grant certain allocations based on power budget considerations affected by the MPR of user equipment 10.

[0063] Figure 10 Each region depicted can be based on parameterized conditions defined by the following equations or relations. These parameterized conditions define what MPR is used for the associated region, and due to these conditions, the region can be fine-tuned for various channel bandwidths, subcarrier spacings, and shaping filter coefficients. It should be noted that the parameter values ​​described below are merely examples, and the exact parameter values ​​can change (e.g., depending on the shaping filter that can be used or applied). However, the conditions and parameters can be described independently of the channel bandwidth and subcarrier spacing, and to some extent, also independently of the various shaping filters. This means there is no inherent need to adjust the parameter settings when the bandwidth and subcarrier spacing change, and a single set of parameters may suffice. For example, for certain bandwidths, subcarrier spacings, and shaping filters, the parameters used for… Figure 10 The parameters for each region depicted are as follows:

[0064] parameter Parameter value c0 6 c1 <![CDATA[ceil(N RB / 3)]]> c2 <![CDATA[ceil(N RB / 20)]]> c3 <![CDATA[ceil(N RB / 8)]]> c4 0.25 c5 0.75 c6 3 c7 3 c8 c1+4 c9 <![CDATA[floor(N RB / 2)]]> c10 <![CDATA[N RB -3]]> c11 0.25 c12 0.75 c13 4 c14 <![CDATA[ceil(N RB / 10)]]>

[0065] Figure 10The region depicted can be defined using parameter values ​​(e.g., values ​​included in the table above), as follows: Region A1 1002 can include two segments and can be defined as: RB_start ≤ c1; and RB_start ≥ N RB -c8; where LCRB≤c0.

[0066] Region A2 1004 can include two segments and can be defined as:

[0067] RB_start≤c2; and

[0068] RB_start≥N RB -LCRB-c2;

[0069] Among them 0 <LCRB≤c3。

[0070] If c14 < LCRB < 9, then region A3 1006 can be defined as:

[0071] floor(N RB *c11-LCRB*c5-c6+c7) <RB_start<floor(N RB *c12-LCRB*c5+c13-c6).

[0072] If LCRB≤c14, then region A3 1006 can be defined as:

[0073] c1 <RB_start<N RB -c8.

[0074] Area A4 1008 can include four segments and can be defined as follows:

[0075] floor(N RB *c11-LCRB*c5-c6)≤RB_start≤floor(N RB *c11-LCRB*c5-c6+c7);

[0076] floor(N RB *c11-LCRB*c4-c6)≤RB_start≤floor(N RB *c11-LCRB*c4-c6+c7);

[0077] floor(N RB *c12-LCRB*c5+c13-c6)≤RB_start≤floor(N RB *c12-LCRB*c4+c13-c6+c7);

[0078] floor(N RB *c12-LCRB*c4+c13-c6)≤RB_start≤floor(N RB *c12-LCRB*c4+c13-c6+c7);

[0079] Where c0 <LCRB<c10。

[0080] Region A5, 1010, can be defined as LCRB≥c10.

[0081] Area A6 1012 can be defined as any resource block allocation, as long as it is not part of Area A1 1002, Area A2 1004, Area A3 1006, Area A4 1008, or Area A5 1010.

[0082] Figure 10 The region definitions depicted can be modified in several ways. For example, if some regions overlap with another region, those regions can be excluded (e.g., if region A4 1008 overlaps with region A2 1004, region A4 1008 can be excluded). Furthermore, the region definitions can be modified to adjust the shape of the regions. For example, Figure 11 It is based on the implementation scheme of this disclosure and Figure 10 The figure depicted is similar to the one with modified A2 region 1102.

[0083] The modified A2 area can include two segments and can be defined as:

[0084] c0+RB_start <LCRB≤c3;c0+(N RB -LCRB-RB_start)<LCRB≤c3.

[0085] and Figure 10 Compared to the modified shape of A2 region 1004 depicted, the modified shape of A2 region 1102 can achieve more efficient coverage of the low-power boost resource block allocation corresponding to A2 region 1102. Therefore, the region definition and / or the parameter values ​​used in the region definition can be modified to provide increased or maximized coverage of resource block allocations that achieve power boost (e.g., resource block allocations characterized by low MPR). In addition to excluding overlapping regions and / or reshaping regions, regions can be repositioned, completely removed, and / or new regions can be added.

[0086] Figure 12This is a flowchart of method 1200 according to an embodiment of the present disclosure, which is used to determine resource block allocation for a resource block allocation region, provide resource block allocation to user equipment 10, and enable user equipment 10 to communicate with base station 304 based on the resource block allocation. Method 1200 can be executed by any suitable device (e.g., a controller) that can control components of user equipment 10 (such as processor 12). In some embodiments, method 1200 can be implemented by using processor 12 to execute instructions stored in a tangible, non-transitory computer-readable medium such as memory 14 or storage device 16. For example, method 1200 can be executed at least in part by one or more software components (such as the operating system of user equipment 10, one or more software applications of user equipment 10, etc.). Although method 1200 is described using a specific order of steps, it should be understood that the steps described herein are contemplated to be performed in a different order than shown, and some described steps may be skipped or not performed at all.

[0087] In process block 1202, user equipment 10 identifies or detects one or more base stations 306. In process block 1204, user equipment 10 synchronizes with base station 306 (e.g., by aligning the timing of user equipment 10 with the timing of base station 306). In process block 1206, base station 306 identifies multiple available resource block allocations. Base station 306 may continuously or periodically monitor resource block allocations for multiple channels to determine which resource block allocations are available or which are used to schedule other devices connected to the network. In some embodiments, the network may identify the multiple available resource block allocations and transmit the available resource block allocations to base station 306. In process block 1208, base station 306 receives an indication of the location of user equipment 10. The location may be determined by user equipment 10 itself (e.g., via Global Navigation Satellite System (GNSS) location service) and / or by base station 306 (e.g., based on an indication of signal strength or quality between user equipment 10 and base station 306).

[0088] In process block 1210, base station 306 determines resource block allocations corresponding to one or more resource block allocation regions. For example, base station 306 may schedule resource block allocations based on the location of user equipment 10 determined in process block 1210. If base station 306 determines that user equipment 10 is close to the base station (e.g., at a distance below a distance threshold), base station 306 may schedule resource block allocations corresponding to a low power boost region (e.g., A11002). If base station 306 determines that user equipment 10 is at a greater distance from base station 306 (e.g., towards the edge of network 302), base station 306 may schedule resource block allocations corresponding to a high power boost region (e.g., region A31006), because operating in a power boost region (e.g., with corresponding low MPR constraints) is useful for establishing high-quality network connectivity (e.g., including signals with a signal-to-noise ratio below a threshold).

[0089] In process block 1212, base station 306 transmits resource block allocations corresponding to one or more resource block allocation regions in the resource block allocation area to user equipment 10. In process block 1214, base station 306 transmits an indication of the MPR value corresponding to the resource block allocation. For example, base station 306 may store multiple MPR values ​​corresponding to multiple resource block allocation regions in a data structure, such as a lookup table, and transmit that data structure to user equipment 10. In process block 1216, user equipment 10 transmits a signal based on the resource block allocation and / or the indication of the MPR value. If base station 306 schedules resource block allocations, user equipment 10 may refer to the indication of the MPR value (e.g., stored in a data structure) to determine how much output power should be applied (or reduced) when transmitting a signal. In this way, flowchart 1200 determines the resource block allocation of the resource block allocation region, provides the resource block allocation to user equipment 10, and enables user equipment 10 to communicate with base station 304 based on the resource block allocation.

[0090] One embodiment includes a base station comprising a receiver, a transmitter, and processing circuitry communicatively coupled to the receiver and the transmitter. The processing circuitry can determine a plurality of resource block allocation areas; determine a plurality of available resource block allocations; receive an indication of user equipment via the receiver; determine the location of the user equipment; determine the resource block allocations of the plurality of resource block allocation areas based on the location; transmit a first indication of the resource block allocation via the transmitter; and transmit a second indication via the transmitter corresponding to a maximum power reduction value for the resource block allocation, wherein the user equipment is configured to transmit signals in a power-up mode based on the first and second indications.

[0091] The resource block allocation region is defined by the spectral shaping filter, the length of the consecutively allocated resource blocks, and the starting resource block.

[0092] The base station's processing circuitry can determine a first resource block allocation corresponding to a high-power enhancement region based on a location indication distance above a distance threshold from the user equipment, and transmit the first resource block allocation to the user equipment to enable the user equipment to transmit the signal in the high-power enhancement region. The base station's processing circuitry can also determine a second resource block allocation corresponding to a low-power enhancement region based on a location indication distance below the distance threshold from the user equipment, and transmit the second resource block allocation to the user equipment to enable the user equipment to transmit the signal in the low-power enhancement region.

[0093] The processing circuitry of the base station can determine the multiple resource block allocation regions by defining multiple parameterized conditions, which are independent of channel bandwidth, subcarrier spacing, shaping filter coefficients, or any combination thereof.

[0101] The multiple resource block allocation regions are defined based on multiple parameterization conditions that are independent of channel bandwidth, subcarrier spacing, and shaping filter coefficients.

[0102] The method further includes determining, via the processing circuitry, that a first region in the plurality of resource block allocation regions overlaps with a second region in the plurality of resource block allocation regions; determining, via the processing circuitry, that the first region enables the user equipment to transmit signals in the power-up mode; and avoiding the selection of resource block allocations corresponding to the second region via the processing circuitry.

[0103] The region within the multiple resource block allocation area includes a first resource block and multiple contiguous resource blocks. The first resource block includes an index that is less than or equal to a ceiling function of the total number of resource blocks in a given channel bandwidth divided by 3 and greater than or equal to the difference between the total number of resource blocks in the given channel bandwidth and the sum of 4 plus the ceiling function of the total number of resource blocks in the given channel bandwidth divided by 3. The multiple contiguous resource blocks include a length greater than or equal to 6.

[0105] In one embodiment, a tangible non-transitory computer-readable medium includes computer-readable instructions that, when executed by one or more processors, cause the processors to determine a plurality of resource block allocation regions; determine an available resource block allocation corresponding to at least one of the plurality of resource block allocation regions; and transmit a first indication of the available resource block allocation to a user equipment, wherein transmitting the available resource block allocation causes the user equipment to transmit a signal in a power-up mode.

[0107] The multiple resource block allocation regions are defined by the spectral shaping filter, the length of the consecutively allocated resource blocks, and the starting resource block for the allocation.

[0108] The tangible, non-transitory computer-readable medium contains computer-readable instructions that, when executed by one or more processors, cause the one or more processors to issue a second indication corresponding to a maximum power reduction value allocated to the resource block; and, based on the maximum power reduction value, cause the user equipment to reduce the output power of the signal.
