According to one embodiment, the third RFFE 236 may be formed as part of the third RFIC 226 .

The electronic device 101, according to one embodiment, may include a fourth RFIC 228 separately from or at least as part of the third RFIC 226. In this case, the fourth RFIC 228 converts the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as an IF signal) of an intermediate frequency band (eg, about 9 GHz to about 11 GHz). After conversion, the IF signal may be transmitted to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. Upon reception, a 5G Above6 RF signal may be received from a second cellular network 294 (eg, a 5G network) via an antenna (eg, antenna 248) and converted to an IF signal by a third RFIC 226. there is. The fourth RFIC 228 may convert the IF signal into a baseband signal so that the second communication processor 214 can process it.

According to one embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as a single chip or at least part of a single package. According to various embodiments, when the first RFIC 222 and the second RFIC 224 in FIG. 2A or 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC is connected to the first RFFE 232 and the second RFFE 234 to convert the baseband signal into a signal of a band supported by the first RFFE 232 and/or the second RFFE 234, , The converted signal may be transmitted to one of the first RFFE 232 and the second RFFE 234. According to one embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as a single chip or at least part of a single package. According to one embodiment, at least one antenna module of the first antenna module 242 or the second antenna module 244 may be omitted or combined with another antenna module to process RF signals of a plurality of corresponding bands.

According to one embodiment, third RFIC 226 and antenna 248 may be disposed on the same substrate to form third antenna module 246 . For example, the wireless communication module 192 or processor 120 may be disposed on a first substrate (eg, main PCB). In this case, the third RFIC 226 is provided on a part (eg, lower surface) of the second substrate (eg, sub PCB) separate from the first substrate, and the antenna 248 is placed on another part (eg, upper surface). is disposed, the third antenna module 246 may be formed. By arranging the third RFIC 226 and the antenna 248 on the same substrate, it is possible to reduce the length of the transmission line therebetween. This, for example, can reduce loss (eg, attenuation) of a signal of a high frequency band (eg, about 6 GHz to about 60 GHz) used in 5G network communication by a transmission line. As a result, the electronic device 101 can improve the quality or speed of communication with the second network 294 (eg, 5G network).

According to an example, antenna 248 may be formed as an antenna array comprising a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC 226 may include, for example, a plurality of phase shifters 238 corresponding to a plurality of antenna elements as part of the third RFFE 236 . During transmission, each of the plurality of phase shifters 238 may convert the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (eg, a base station of a 5G network) through a corresponding antenna element. . Upon reception, each of the plurality of phase shifters 238 may convert the phase of the 5G Above6 RF signal received from the outside through the corresponding antenna element into the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device 101 and the outside.

The second cellular network 294 (eg, 5G network) may be operated independently (eg, Stand-Alone (SA)) or connected to the first cellular network 292 (eg, a legacy network) ( Example: Non-Stand Alone (NSA)). For example, a 5G network may include only an access network (eg, a 5G radio access network (RAN) or a next generation RAN (NG RAN)) and no core network (eg, a next generation core (NGC)). In this case, after accessing the access network of the 5G network, the electronic device 101 may access an external network (eg, the Internet) under the control of a core network (eg, evolved packed core (EPC)) of the legacy network.

3A is a flowchart illustrating an operating method of an electronic device and a network according to a comparative example for comparison with various embodiments. At least one of the operations performed by the electronic device and network according to Comparative Example may be performed by the electronic device and network according to various embodiments.

The electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the unified communication processor 260) requests a scheduling request in operation 301. A message (hereinafter, which may be mixed with a scheduling request (SR) message) may be transmitted to the network 300 . The network 300 may be, for example, a base station, but is not limited as long as it is a device that supports the origin of allocating resources to the electronic device 101, and for example, for causing at least one operation of the network 300 It may include at least one storage circuit for storing instructions and at least one processing circuit for executing instructions. For example, the electronic device 101 may transmit a scheduling request message to the network 300 based on generation (or confirmation) of uplink data to be transmitted to the network 300 . The network 300 may determine whether to allocate uplink resources, for example, PUSCH resources, to the electronic device 101 based on the received scheduling request message. If it is confirmed that uplink resources, for example, PUSCH resources are to be allocated to the electronic device 101, the network 300 may transmit DCI to the electronic device 101 in operation 303. The DCI may correspond to, for example, a UL grant, and may include information associated with allocated uplink resources. For example, the DCI includes information associated with allocated uplink resources (eg, information included in a resource allocation field), and/or information for confirming the associated information. can Information associated with uplink resources (eg, information included in the resource allocation field includes, for example, the starting resource block (RB _START ) and the length of an adjacent allocated resource block (length in terms of contiguously A resource indication value (RIV) corresponding to allocated resource blocks (L _CRBs ) may be included, but this is merely exemplary (eg, as an example for uplink resource allocation type 0), and the electronic device 101 There is no limitation as long as the information is used to identify the allocated uplink resources, for example, the information for allocating the uplink resources, or the allocation method, is based on the standard ^3rd generation partnership project (3GPP) technical specification (TS). 36.213 or TS 38.214 may be followed, but this is also exemplary and is not limited. If the length (L _CRBs ) of an adjacent allocated resource block is a relatively large value (eg, 30), the electronic device 101 ) may mean that an uplink resource of a relatively large size, for example, PUSCH, is allocated, and the length of the allocated resource block (L _CRBs ) is relatively small (eg, 10). This may mean that an uplink resource of a relatively small size, for example, a PUSCH, is allocated to the device 101 .

In operation 305, the electronic device 101 may check at least one resource allocated to the electronic device 101 based on the received DCI. For example, the electronic device 101 may identify at least one allocated resource, for example, a PUSCH resource, based on the RIV identified based on the received DCI, but as described above, the identification method and It will be appreciated by those skilled in the art that there is no limitation on the information for identification. In operation 307, the electronic device 101 may transmit uplink data using at least one resource, for example, a PUSCH resource. The network 300 according to the comparative example may determine the size of resources allocated to the electronic device 101, but may not be determined based on the size of uplink data to be transmitted by the electronic device 101. Accordingly, when the size of uplink data to be transmitted by the electronic device 101 is relatively small, the network 300 according to the comparative example may allocate a relatively large size of uplink resources, or When the size of uplink data to be transmitted by the device 101 is relatively large, there is a possibility of allocating a relatively small size of uplink resource. If the size of uplink data to be transmitted by the electronic device 101 is relatively small, the electronic device 101 and the network 300 according to a comparative example of a case in which a relatively large size of uplink resource is allocated The operation of will be described with reference to FIG. 3B.

3B is a flowchart illustrating an operating method of an electronic device and a network according to a comparative example for comparison with various embodiments. At least one of the operations performed by the electronic device and network according to Comparative Example may be performed by the electronic device and network according to various embodiments.

The electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the unified communication processor 260) requests scheduling in operation 311. A message may be sent to network 300 . The network 300 may transmit the DCI corresponding to the scheduling request message to the electronic device 101 in operation 313 . In operation 315, the electronic device 101 may check at least one resource allocated to the electronic device 101 based on the DCI. The electronic device 101 may transmit a buffer state reporting (BSR) message to the network 300 in operation 317 based on at least one allocated resource. For example, when the size of a resource allocated to the electronic device 101 is relatively small, the electronic device 101 may transmit a B scheduling request message causing expansion of the size of the allocated resource to the network 300. there is. The B scheduling request message may include information on how much data is present in the buffer of the electronic device, but is not limited thereto. Based on the B scheduling request message, the network 300 may transmit DCI for checking resources allocated to the electronic device 101 to the electronic device 101 in operation 319 . Meanwhile, in the comparative example of FIG. 3B , it is shown that the electronic device 101 transmits the B scheduling request message once, but this is exemplary and the electronic device 101 transmits the B scheduling request message multiple times. may be In operation 321, the electronic device 101 may check at least one resource allocated to the electronic device 101 based on the received DCI. In operation 323, the electronic device 101 may transmit uplink data using at least one resource, for example, a PUSCH resource. As described above, when the size of data in the buffer of the electronic device 101 is relatively large, the electronic device 101 may transmit the B scheduling request message a plurality of times, thereby increasing overhead, and/or Alternatively, a problem in which transmission time of UL data is delayed may occur.

4A is a flowchart illustrating a method of operating an electronic device and a network according to various embodiments. The embodiment of FIG. 4A will be described with reference to FIG. 4B. 4B is a diagram for explaining the size of allocated resources for each received strength measured in a network according to various embodiments.

According to various embodiments, the electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260), In operation 401, a scheduling request message may be transmitted to the network 300 through at least one first resource (eg, at least one resource of a physical uplink control channel (PUCCH)). For example, the electronic device 101 determines the transmission strength of the scheduling request message based on the size of uplink data to be transmitted, for example, the output power of the RF signal corresponding to the scheduling request message (or the transmission power of the PUCCH). ) can be determined, which will be described later. The network 300 may check the scheduling request message received through at least one first resource (eg, at least one resource of PUCCH) in operation 403 . Meanwhile, the fact that the physical channel through which the scheduling request message is transmitted is PUCCH is simply exemplary, and there is no limitation on the transmission channel.

According to various embodiments, the network 300 may check the reception strength of the scheduling request message in operation 405 . For example, the network 300 may measure reception strength in at least one first resource (eg, at least one resource of PUCCH). The reception strength may include, for example, at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), reference signal strength indicator (RSSI), or signal to interference-plus-noise ratio (SINR). , as long as it is an index related to the magnitude of the RF signal to be identified, it will be understood by those skilled in the art that there is no limitation. In operation 407, the network 300 may check at least one resource to be allocated to the electronic device 101, for example, a PUSCH resource, based on the checked reception strength. In one example, the network 300 may preset association information between a plurality of reception strength ranges and a plurality of sizes of allocated resources. Table 1 is an example of association information between a plurality of ranges of reception strength and sizes of a plurality of allocated resources.

Receive strength range Size of allocated resources (e.g., L _CRBs ) 1st range 1st size 2nd range 2nd size 3rd range 3rd size

The related information of Table 1 may be previously stored and/or managed by the network 300, for example. A configuration in which the network 300 sets the related information as shown in Table 1 will be described later. When there are a plurality of connected user devices, the network 300 may separately manage related information as shown in Table 1 for each of the plurality of user devices. For example, referring to FIG. 4B , the electronic device 101 may set at least one threshold value (Th1, Th2, Th3) for classifying a range of reception strength measured on a PDCCH. For example, when a received strength smaller than the first threshold value Th1 is measured (eg, when the received strength is included in the 0th range 461), the network 300, on the PDCCH It may be determined that the scheduling request message is not received. For example, when a received strength greater than the first threshold value Th1 and smaller than the second threshold value Th2 is measured (eg, when the received strength is included in the first range 462), , the network 300 may check the first size corresponding to the first range of Table 1. For example, when a received strength greater than the second threshold value Th2 and smaller than the third threshold value Th3 is measured (eg, when the received strength is included in the second range 463), , the network 300 may check the second size corresponding to the second range of Table 2. For example, when the received strength greater than the second threshold Th2 is measured (eg, when the received strength is included in the third range 464), the network 300, Table 1 A third size corresponding to the third range of can be identified. The network 300 may check the size of the allocated resource corresponding to the range including the checked reception strength in operation 405 by referring to the association information. For example, in operation 405, the network 300 transmits a corresponding scheduling request message when the checked reception strength (eg, reception strength 470 of FIG. 4B) is included in the second range of Table 1. A size of a resource to be allocated to one electronic device 101 may be determined as a second size corresponding to a second range. Meanwhile, the method of determining the size of resources to be allocated based on the association information as shown in Table 1 is merely exemplary, and those skilled in the art will understand that there is no limitation as long as the size of the reception strength corresponds to the size of the allocated resources.

According to various embodiments, the network 300 may transmit, in operation 409 , DCI including information for identifying at least one resource, eg, a PUSCH resource, to the electronic device 101 . In operation 411, the electronic device 101 may check at least one resource allocated to the electronic device 101, for example, a PUSCH resource, based on the DCI. In operation 413, the electronic device 101 may transmit uplink data to the network 300 through the identified at least one resource, for example, a PUSCH resource.

As described above, the electronic device 101 can transmit a scheduling request message with a transmission size corresponding to a case where the size of uplink data to be transmitted is relatively small, and the network 300 determines the reception strength of the scheduling request message. Corresponding to , a relatively small PUSCH may be allocated to the electronic device 101 . Alternatively, the electronic device 101 may transmit a scheduling request message with a transmission size corresponding to a case in which the size of uplink data to be transmitted is relatively large, and the network 300 may transmit the scheduling request message in response to the reception strength of the scheduling request message. A relatively large PUSCH may be allocated to the electronic device 101 . Accordingly, waste of resources operated by the network 300, transmission delay of uplink data through the PUSCH, or increase in overhead (eg, additional transmission of the B scheduling request message) can be alleviated.

5A is a flowchart illustrating a method of operating an electronic device according to various embodiments.

According to various embodiments, the electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260), In operation 501, the size of uplink data to be transmitted can be checked. For example, the electronic device 101 may check the size of data stored in the buffer as the size of uplink data to be transmitted, but this is an example, and a method for checking the size of uplink data to be transmitted, or There are no restrictions on the type of data to be used. In operation 503, the electronic device 101 may check the size of transmission power of the scheduling request message based on the size of uplink data to be transmitted. In one example, the electronic device 101 may store and/or manage association information between a size range of uplink data to be transmitted and a size of transmission power. Table 2 is an example of association information between the size of uplink data to be transmitted and the size of transmission power.

Size range of uplink data to be transmitted size of transmission power 1st range 1st size 2nd range 2nd size 3rd range 3rd size

For example, when the size of uplink data is included in the second range, the electronic device 101 may determine the second size corresponding to the second range as the transmit power of the RF signal corresponding to the scheduling request message. . The magnitude of transmit power may be expressed in units of dBm in one example. Alternatively, in another example, the size of the transmission power may be expressed as a percentage of the maximum transmission power corresponding to the PUSCH, in which case the first size is 80%, the second size is 90%, and the second size is 90%. 3 Magnitude can be expressed as 100%, for example. When 90% is selected, the electronic device 101 transmits an RF signal with a transmit power corresponding to 90% of the maximum transmit power corresponding to the PUSCH set based on a standard (eg, 3GPP TS 36.213 or TS 38.213). You can decide what to offer. The configuration for obtaining the relevant information of Table 2 will be described later.

The electronic device 101 according to various embodiments may, in operation 505, provide an RF signal corresponding to the scheduling request message having the checked transmit power level. In various embodiments, controlling to provide an RF signal corresponding to a scheduling request message having a size of the checked transmit power is performed by, for example, an RF circuit such that the RF signal having the size of the checked transmit power is input to at least one antenna port. (eg, at least one RFIC and/or at least one RFFE), but is not limited thereto.

5B is a flowchart illustrating a method of operating an electronic device according to various embodiments.

According to various embodiments, the electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260), In operation 511, the size of uplink data to be transmitted can be checked. In operation 513, the electronic device 101 may check whether the size of uplink data is greater than or equal to a threshold size. If the size of the uplink data is greater than or equal to the critical size (513 - Yes), the electronic device 101 may provide, in operation 515, an RF signal corresponding to the scheduling request message having the first transmit power level. . If the size of the uplink data is less than the critical size (513-No), the electronic device 101 may provide an RF signal corresponding to the scheduling request message having the second transmit power in operation 517. For example, in operations 515 and 517, it is assumed that the transmission power of the PUCCH set at least based on information from the network is the same. The electronic device 101 may determine transmit power of RF signals corresponding to different scheduling request messages according to the size of uplink data in a state in which transmit power of the same PUCCH is set. For example, when the transmit power of the PUCCH is set to a first size (eg, A dBm), if the size of data to be transmitted is the first data size, the RF of the first size (eg, A dBm) At least one RFIC and/or at least one RFFE may be controlled so that a signal is input to the antenna port. For example, when the transmit power of the PUCCH is set to the second size (eg, B dBm), if the size of data to be transmitted is a second data size different from the first data size, the third size (eg, B dBm) , C dBm) of at least one RFIC and / or at least one RFFE may be controlled so that the RF signal is input to the antenna port. Here, any one of the second magnitude (eg, B dBm) and the third magnitude (eg, C dBm) may be the same as the first magnitude (eg, A dBm), but is not limited thereto. .

6 is a flowchart illustrating a method of operating an electronic device and a network according to various embodiments.

According to various embodiments, the electronic device 101 (eg, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260), In operation 601, a first transmit power may be determined as transmit power of an RF signal corresponding to the scheduling request message. The electronic device 101 may transmit a first scheduling request message to the network 300 in operation 603 . The electronic device 101 may control an RF signal of the first transmission power to be input to the antenna port, and accordingly, the first scheduling request message may be transmitted. The network 300 may check at least one first resource to be allocated to the electronic device 101 based on the checked first reception strength in operation 605 . As described above, the network 300 may allocate PUSCH resources based on the reception strength, and accordingly, may identify at least one first resource corresponding to the first reception strength. The network 300 may transmit a first DCI including information for identifying at least one first resource to the electronic device 101 in operation 607 . In operation 609, the electronic device 101 may associate and store the first transmission power and the at least one first resource. The electronic device 101 may identify at least one first resource based on at least information included in the first DCI, associate the identified at least one first resource with the first transmission power, and store the first transmission power. The above operations may be performed for the purpose of setting association information between transmission power and resources allocated from the network 300, not for the purpose of actually transmitting uplink data by the electronic device 101, but this As an example, it may be performed as part of a process of transmitting uplink data, and this may be referred to as a power synchronization operation. The electronic device 101 may perform the power synchronization operation multiple times.

For example, in operation 621, the electronic device 101 may determine the Nth transmit power as the transmit power of the RF signal corresponding to the scheduling request message. The Nth transmit power may be different from the first transmit power. The electronic device 101 may, for example, determine the Nth transmit power greater than the first transmit power, or in another example, may determine the Nth transmit power less than the first transmit power. There is no limit on the adjustment of the transmit power according to the power synchronization operation. The electronic device 101 may transmit the Nth scheduling request message to the network 300 in operation 623 . The electronic device 101 may control an RF signal of the Nth transmission power to be input to the antenna port, and accordingly, the Nth scheduling request message may be transmitted. In operation 625, the network 300 may check at least one Nth resource to be allocated to the electronic device 101 based on the checked Nth reception strength. As described above, the network 300 may allocate PUSCH resources based on the reception strength, and accordingly, at least one Nth resource corresponding to the Nth reception strength may be identified. In operation 627 , the network 300 may transmit the N th DCI including information for identifying at least one N th resource to the electronic device 101 . In operation 629, the electronic device 101 may associate and store the Nth transmission power and at least one Nth resource. The electronic device 101 may identify at least one Nth resource based on at least information included in the Nth DCI, and store the identified at least one Nth resource in association with the Nth transmission power. The electronic device 101 uses association information between the first transmission power and at least one first resource or association information between the N-th transmission power and at least one N-th resource, in operation 631, a plurality of transmission powers and Association information of a plurality of resource sizes may be stored. Association information of a plurality of transmission powers and a plurality of resource sizes may be expressed as, for example, association information between transmission powers and resource sizes.

According to various embodiments, the electronic device 101 may check the generation of uplink data. In operation 633, the electronic device 101 may determine transmission power corresponding to the size of uplink data based on the association information. For example, the electronic device 101 may determine the size of a resource to be allocated corresponding to the size of uplink data, and may determine transmission power corresponding to the size of the determined resource using stored association information. In another example, the electronic device 101 may preset association information between the size of uplink data and transmission power as shown in Table 2, and may determine transmission power based on the association information as shown in Table 2.

For example, the mMTC device may transmit the scheduling request message using transmission power that causes relatively small resources to be allocated. For example, when the electronic device 101 transmits an SMS message, a text message, or an internet control message protocol (ICMP) message, scheduling is performed using transmission power that causes relatively small-sized resources to be allocated. A request message can be sent. For example, when the electronic device 101 uses a video call service, the scheduling request message may be transmitted using transmission power that causes relatively large resources to be allocated.

In operation 703, the electronic device 101 may check the number of sections of transmission power set by the network 300 (or reception strength measured by the network 300) based on information included in the message. . The network 300 may partition and manage a range of reception strength as shown in FIG. 8 , for example. Referring to FIG. 8 , the network 300 may divide a minimum reception strength (eg, 0 dB) and a maximum reception strength (eg, 30 dB) into a plurality of sections 801 , 803 , and 805 . Here, the minimum reception strength (eg, 0 dB) and the maximum reception strength (eg, 30 dB) may correspond to the minimum reception strength and the maximum reception strength that can be measured in the network 300, respectively, but are not limited thereto. For example, the network 300 calculates the average change in short-term fading (

) can be calculated in dB units, and the calculation method is not limited. average change (

) may be determined based on, for example, the reception strength measured on the PUCCH, but this is also not limited. The network 300 can also check the reliability index δ (dB), and the size of one section is the sum of the average change and the reliability index.

It can be set larger than + δ. Here, when the change in short-term fading is large or when the moving speed of the electronic device 101 is high and channel variability is relatively large, a relatively large reliability index may be set. Alternatively, when more reception strength intervals are required, a relatively small reliability index may be set. The network 300 may set the number of intervals 801 , 803 , and 805 as a quotient determined by dividing the difference between the minimum reception strength and the maximum reception strength by the sum of the average change amount and the reliability index. For example, in the embodiment of FIG. 8, accordingly, 3, which is the quotient of dividing 30 dB, which is the difference between the minimum and maximum reception strength, by 10 dB of the average change amount and the reliability index, is set as the number of sections 801, 803, and 805. Accordingly, threshold values of 10 dB and 20 dB for partitioning each section may be determined. In another example, the network 300 may determine a plurality of received strength ranges based on previously measured received strength in a PUCCH allocated for a scheduling request message. For example, when the received strength previously measured in the PUCCH allocated for the scheduling request message is the first received strength, the network 300 determines a plurality of received strengths based on the first received strength. It is also possible to determine the ranges of, and there is no limit to the way. In one example, the network 300 may set the first reception strength as the maximum reception strength and determine a plurality of ranges of reception strength based on this. In another example, the network 300 may set the first reception strength as the minimum reception strength and determine a plurality of ranges of reception strength based thereon. In another example, the network 300 may set thresholds for partitioning ranges of a plurality of reception strengths using the first reception strength (eg, performing an operation designated for the first reception strength), The above-described examples are simple examples, and there is no limitation on a method of setting a plurality of reception strength ranges using the first reception strength.

The electronic device 101 may check the integer described in the IE of sr-PUCCH-PowerLevel included in the IE of SchedulingRequestConfig of the received RRC message, and accordingly, the transmit power partitioned by the network 300 (or the network ( In 300), it is possible to check the number of sections of the measured reception strength). In operation 705, the electronic device 101 may perform the power synchronization operation described with reference to FIG. 6 based on the number of checked sections. For example, when the number of sections is three, the electronic device 101 may perform a power synchronization operation until the number of sizes of resources allocated by the network 300 is three. For example, the electronic device 101 may check the size of the resource allocated based on the DCI received from the network 300 while changing the transmission power of the RF signal corresponding to the scheduling request message. The electronic device 101 changes the transmit power of the RF signal corresponding to the scheduling request message and allocates it by the network 300 until the number of sizes of resources different from the number identified in the RRC message is identified. It is possible to repeat the performance of checking the size of a given resource.
