Description

Electronic device for performing wireless communication and method of operation thereof

[0001] Embodiments of the present disclosure relate to an electronic device for performing wireless communication and a method of operating the same.

[0002] To meet the increasing demand for wireless data traffic since the commercialization of 4G communication systems, efforts are being made to develop 5G communication systems. For this reason, 5G communication systems are also referred to as “beyond 4G networks” or “post-LTE” communication systems. To achieve relatively high data throughput, 5G communication systems are being considered for implementation in bands below 6 GHz (e.g., approximately 3.5 GHz) or higher frequency bands (e.g., approximately 28 GHz or 39 GHz). To mitigate radio path loss and increase the transmission range of radio waves, beamforming, massive MIMO (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antenna technologies are being discussed for 5G communication systems.

[0003] The above information may be provided as background information to aid in understanding this document. None of the above is claimed to be prior art related to this document or can be used to determine prior art.

[0004] When a communication function is activated, an electronic device (e.g., a user equipment (UE)) in a wireless communication system can connect to a specific cell to perform wireless communication. For example, an electronic device can select a cell to connect to based on the frequencies to which the electronic device has connected (e.g., a stored list).

[0005] Electronic devices can preferentially select cells capable of relatively fast wireless communication from frequencies with which they have a connection history (e.g., a stored list). As the functionality required by electronic devices diversifies to meet diverse user needs, if electronic devices preferentially select cells capable of relatively fast wireless communication, they may connect to cells that are not suitable for their intended use.

[0006] Embodiments of the present disclosure disclose a device and method for preferentially selecting a cell corresponding to a characteristic of an electronic device in an electronic device.

[0007] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present disclosure belongs from the description below.

[0008] According to one embodiment, an electronic device may include a communication circuit, at least one processor, and a memory. According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to perform a search for a plurality of frequencies included in a frequency list associated with cell selection. According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to set priorities for the plurality of frequencies based on search results. According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to update priorities for the plurality of frequencies included in the frequency list based on at least one characteristic of the electronic device. According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to perform cell selection based on updated priorities for the plurality of frequencies included in the frequency list.

According to one embodiment, the one or more programs may include instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform the following operations: performing a search for a plurality of frequencies included in a frequency list associated with cell selection; setting priorities of the plurality of frequencies based on a result of the search; updating priorities of the plurality of frequencies included in the frequency list based on at least one characteristic of the electronic device; and performing cell selection based on the updated priorities of the plurality of frequencies included in the frequency list.

[0011] According to an exemplary embodiment of the present disclosure, by updating the priority of a frequency list related to cell selection based on characteristics of the electronic device, a cell corresponding to the intended use of the electronic device can be preferentially selected.

According to one embodiment, the processor (200) may be substantially the same as the processor (120) (e.g., a communication processor) of FIG. 1, or may be included in the processor (120). The communication circuit (210) may be substantially the same as the wireless communication module (192) of FIG. 1, or may be included in the wireless communication module (192). The memory (220) may be substantially the same as the memory (130) of FIG. 1, or may be included in the memory (130). For example, the processor (200) may be operatively, functionally, and / or electrically connected to at least one of the communication circuit (210) or the memory (220). For example, the processor (200) may include at least one processor including a processing circuit.

[0053] According to one embodiment, when the processor (200) detects the occurrence of an event related to cell selection, it may check whether a list of frequencies related to cell selection exists in the memory (220).

For example, the list of frequencies related to cell selection may include information related to at least one frequency for preferentially performing a search for cell selection of the electronic device (101). For example, the list of frequencies related to cell selection may include at least one frequency for which the electronic device (101) has a connection history and a cell parameter related to each frequency.

[0055] According to one embodiment, the processor (200) may set priorities for frequencies included in a frequency list related to cell selection based on frequency-related search results. For example, the processor (200) may set a relatively high priority for frequencies with relatively high (or good) channel state information.

[0056] According to one embodiment, the processor (200) may update the priorities of frequencies included in the frequency list related to cell selection based on the characteristics of the electronic device (101). For example, the characteristics of the electronic device (101) may include performance required for a function (or service, purpose of use) provided by the electronic device (101). For example, the characteristics of the electronic device (101) may be set based on at least one of the execution history of an application program of the electronic device (101), an application program running on the electronic device (101), or a capability (e.g., UE capability) of the electronic device (101).

[0057] For example, the processor (200) may identify (or select) at least one frequency for updating a priority based on at least one characteristic of the electronic device (101) among the frequencies included in the frequency list related to cell selection. For example, the at least one frequency for updating a priority may include a frequency that satisfies a first condition for which channel state information is specified based on a search result related to the frequency. For example, the frequency that satisfies the specified first condition may include a frequency for which channel state information exceeds a specified reference value.

[0058] For example, when the electronic device (101) includes a plurality of characteristics, the processor (200) may sequentially update the priorities of frequencies included in the frequency list related to cell selection based on each characteristic. For example, updating the priorities may include a series of operations for updating the priorities of at least one frequency identified (or selected) based on a search result related to the frequency among the frequencies included in the frequency list related to cell selection.

[0059] For example, the processor (200) may update the priorities of frequencies included in the frequency list related to cell selection based on weights set by at least one characteristic of the electronic device (101). As an example, the priority update may include a series of operations for updating the priorities of at least one frequency identified (or selected) based on a search result related to a frequency among the frequencies included in the frequency list related to cell selection based on a sum of the weights.

[0060] According to one embodiment, the processor (200) may control the communication circuit (210) to perform cell selection using a frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101). For example, the processor (200) may sequentially check whether a cell for camping on exists using each frequency based on the priority of the frequencies included in the frequency list related to cell selection. For example, camping on may include a series of operations to check whether a cell to which the electronic device (101) can connect (or register) exists based on at least one of channel state information of a cell using a designated frequency, a list of prohibited cells for registration, or a service provider of the cell.

[0061] For example, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists by using the frequency with the highest priority in the frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) exists by using the frequency with the highest priority, the processor (200) may confirm (or select) the cell as a cell to which the electronic device (101) can connect (or register). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) does not exist by using the frequency with the highest priority, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists by using the frequency with the next priority.

[0062] For example, if cell selection using frequencies included in a frequency list related to cell selection fails, the processor (200) may control the communication circuit (210) to perform cell selection again using frequencies included in the frequency list related to cell selection. If cell selection using frequencies included in a frequency list related to cell selection fails a specified number of times, the processor (200) may control the communication circuit (210) to perform a search (e.g., full scan) related to a frequency (or frequency band) supported by the electronic device (101). As an example, a failure in cell selection may include a state in which a cell for camping on the electronic device (101) is not detected using frequencies included in a frequency list related to cell selection.

[0063] According to one embodiment, when the processor (200) selects a cell that the electronic device (101) can access using the frequency list related to cell selection, the processor (200) may update the frequency list related to cell selection based on the system information of the corresponding cell. For example, the processor (200) may check (or obtain) additional frequency information from system information (e.g., SIB 4) received from a cell that the selected electronic device (101) can access using the frequency list related to cell selection. The processor (200) may add the additional frequency information to the frequency list related to cell selection. For example, the additional frequency information may be added to the frequency list related to cell selection with a relatively low priority. For example, the additional frequency information may include information related to a frequency (e.g., inter frequency) of a neighboring cell that is different from the frequency of the cell that the electronic device (101) can access using the frequency list related to cell selection.

[0064] According to one embodiment, the processor (200) may control the communication circuit (210) to perform a search (e.g., full scan) related to frequencies (or frequency bands) supported by the electronic device (101) if a list of frequencies related to cell selection does not exist in the memory (220). The processor (200) may perform cell selection based on the results of the search (e.g., full scan) related to frequencies (or frequency bands) supported by the electronic device (101).

[0065] According to one embodiment, the communication circuit (210) may support wireless communication between the electronic device (101) and an external electronic device (e.g., a base station, the electronic device (102 or 104) of FIG. 1, or a server (108)). As an example, the wireless communication may include cellular communication (e.g., long term evolution (LTE) and / or new radio (NR)).

[0066] According to one embodiment, the memory (220) may store various data used by at least one component (e.g., the processor (200) or the communication circuit (210)) of the electronic device (101). For example, the memory (220) may store various instructions that may be executed by the processor (200). For example, the instructions may be executed individually or collectively by the processor (200) (e.g., at least one processor).

[0067] According to one embodiment, the electronic device (101) may set priorities for frequencies included in a frequency list associated with cell selection based on characteristics of the electronic device (101). For example, the electronic device (101) may omit a search (e.g., power scan) associated with at least one frequency included in the frequency list associated with cell selection.

[0068] According to one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1 or FIG. 2) may include a communication circuit (e.g., wireless communication module (192) of FIG. 1 or communication circuit (210) of FIG. 2), at least one processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2), and a memory (e.g., memory (130) of FIG. 1 or memory (220) of FIG. 2). According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to perform a search for a plurality of frequencies included in a frequency list associated with cell selection. According to one embodiment, the memory may store instructions that, when individually or collectively executed by the at least one processor, cause the electronic device to set priorities for the plurality of frequencies based on the search results. According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to update priorities of a plurality of frequencies included in a frequency list based on at least one characteristic of the electronic device. According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to perform cell selection based on updated priorities of a plurality of frequencies included in the frequency list.

[0069] According to one embodiment, the instructions may include instructions that, when executed individually or collectively by at least one processor, cause the electronic device to determine at least one characteristic of the electronic device based on at least one of an execution history of an application program of the electronic device, an application program running on the electronic device, or a capability of the electronic device.

[0070] According to one embodiment, at least one characteristic of the electronic device may include at least one of a redcap-related function, a power reduction function, high reliability, high transmission rate, or service area.

[0071] According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may include instructions that cause the electronic device to set a relatively high priority for a relatively high frequency of channel state information based on the search results.

[0072] According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may include instructions that cause the electronic device to identify at least one frequency for updating a priority among a plurality of frequencies included in a frequency list associated with cell selection based on a search result. According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may include instructions that cause the electronic device to update a priority of at least one frequency included in the frequency list based on at least one characteristic of the electronic device.

[0073] According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may include instructions that cause the electronic device to sequentially update priorities of a plurality of frequencies included in a frequency list based on each characteristic, when considering a plurality of characteristics of the electronic device.

[0074] According to one embodiment, the instructions, when individually or collectively executed by at least one processor, may include instructions that cause the electronic device to set a weight for each of a plurality of frequencies included in the frequency list based on each characteristic of the electronic device. According to one embodiment, the instructions, when individually or collectively executed by at least one processor, may include instructions that cause the electronic device to update a priority of a plurality of frequencies included in the frequency list based on a sum of the weights.

[0075] According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may include instructions that cause the electronic device to perform cell selection using each frequency included in the frequency list sequentially based on the updated priority.

[0076] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to obtain additional frequency information based on system information obtained from a cell selected for cell selection. According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to add the additional frequency information to a frequency list with a relatively low priority.

[0077] FIG. 3 is a flowchart (300) for updating the priority of a frequency list related to cell selection in an electronic device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 3 may be the electronic device (101) of FIG. 1 or FIG. 2.

[0078] According to one embodiment referring to FIG. 3, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2) may perform a scan or search for a frequency list related to cell selection in operation 301. For example, when the processor (200) detects the occurrence of an event related to cell selection, the processor (200) may check whether a frequency list related to cell selection exists in the memory (220). For example, a state in which an event related to cell selection occurs may include at least one of a state in which a communication circuit (210) that was disabled is activated, a state in which the electronic device (101) is determined to have left a shaded area, or a state in which a communication restriction (e.g., airplane mode) of the electronic device (101) is released. For example, the frequency list related to cell selection may include information related to at least one frequency for preferentially performing a search for cell selection of the electronic device (101). For example, a list of frequencies related to cell selection may include at least one frequency for which an electronic device (101) has a connection history and a cell parameter related to each frequency, as shown in Table 1.

[0080] For example, the cell variable may include cell configuration information identified in the system information (e.g., SIB) of the cell supporting the corresponding frequency, as shown in Table 2.

[0082] For example, support for a feature related to reduced capability (redcap) may be determined based on at least one of "halfDuplexRedCap-Allowed", "cellBarredRedCap1Rx", "cellBarredRedCap2Rx" or "intraFreqReselectionRedCap" identified in SIB 1. For example, a service area (e.g., coverage) may be determined based on "intraFreqReselectionRedCap" identified in SIB 1. For example, support for a power reduction feature may be determined based on at least one of "eDRX-Allowedidle" identified in SIB 1 or "relaxedMeasurement" identified in SIB 2. For example, support for a power reduction function can be determined based on at least one of "UAI power saving", "CDRX (connected mode DRX (discontinuous reception))" or "CDRX longDrxCycleLength" confirmed through an RRC (radio resource control) message (e.g., RRC reconfiguration) related to an RRC connection. For example, support for a high data rate (eMBB: enhanced mobile broadband) can be determined based on at least one of bandwidth, modulation or subcarrier spacing (SCS).For example, whether ultra reliable and low latency communication (URLLC) is supported can be determined based on at least one of the following: whether PDCP (packet data convergence protocol) duplication is used, whether Configured Grant is used, or whether mini-slots are set, as confirmed through an RRC message (e.g., RRC reconfiguration) related to the RRC connection.

[0083] For example, if a list of frequencies related to cell selection exists in the memory (220), the processor (200) may control the communication circuit (210) to perform a search (e.g., power scan) related to at least one frequency included in the list of frequencies related to cell selection. For example, the search (e.g., power scan) related to the frequency may include a series of operations for checking channel state information of each frequency included in the list of frequencies related to cell selection. For example, the channel state information may include at least one of a received signal strength indication (RSSI), a reference signal received quality (RSRQ), a reference signal received power (RSRP), a signal to noise ratio (SNR), a signal to interference and noise ratio (SINR), a quality of service (QoS), a block error rate (BLER), a modulation and coding scheme (MCS), or a bit error rate (BER).

[0084] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, in operation 303, set priorities of frequencies included in a frequency list associated with cell selection based on a search result for the frequency list associated with cell selection. For example, the processor (200) may set a relatively high priority for a frequency having relatively high (or good) channel state information.

[0085] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, in operation 305, update the priorities of frequencies included in a frequency list related to cell selection based on at least one characteristic of the electronic device (101). For example, the characteristic of the electronic device (101) may include performance required by a function (or service) provided by the electronic device (101), as shown in Table 3. For example, the characteristic of the electronic device (101) may be set based on at least one of an execution history of an application program of the electronic device (101), an application program running on the electronic device (101), or a capability (UE capability) of the electronic device (101).

[0087] For example, the characteristics of the electronic device (101) may include at least one of reduced capability, high reliability, high transmission rate, or service area when the electronic device (101) is a virtual reality (VR) device (or an augmented reality (AR) device) that supports reduced capability. For example, the characteristics of the electronic device (101) may include at least one of high reliability, high transmission rate, or service area when the electronic device (101) is a VR device. For example, the characteristics of the electronic device (101) may include at least one of reduced capability, or reduced power when the electronic device (101) is a stationary sensor (or a stationary sensor device). For example, the characteristics of the electronic device (101) may include at least one of reduced capability, high transmission rate, or service area when the electronic device (101) is a first state wearable device (e.g., a watch) that supports reduced capability. For example, the characteristic of the electronic device (101) may include at least one of reduced capability, high transmission rate, or reduced power when the electronic device (101) is a wearable device (e.g., a watch) in a second state that supports reduced capability. For example, the characteristic of the electronic device (101) may include at least one of high transmission rate or service area when the electronic device (101) is a wearable device (e.g., a watch) in a first state. For example, the characteristic of the electronic device (101) may include at least one of high transmission rate or reduced power when the electronic device (101) is a wearable device (e.g., a watch) in a second state. For example, the first state may include a state in which the remaining battery capacity of the electronic device (101) exceeds a specified reference remaining capacity. For example, the second state may include a state in which the remaining battery capacity of the electronic device (101) is less than or equal to a specified reference remaining capacity.

[0088] For example, the processor (200) can update the priority of frequencies included in the frequency list related to cell selection based on at least one characteristic of the electronic device (101).

[0089] For example, the processor (200) may identify (or select) at least one frequency for updating a priority based on at least one characteristic of the electronic device (101) among the frequencies included in the frequency list related to cell selection. For example, the at least one frequency for updating a priority may include a frequency that satisfies a first condition for which channel state information is specified based on a search result related to the frequency. For example, the frequency that satisfies the specified first condition may include a frequency for which channel state information exceeds a specified reference value.

[0090] For example, the processor (200) may sequentially update the priorities of frequencies included in the frequency list related to cell selection based on each characteristic of the electronic device (101). For example, updating the priorities may include a series of operations for updating the priorities of at least one frequency identified (or selected) based on a search result related to the frequency among the frequencies included in the frequency list related to cell selection.

[0091] For example, the processor (200) may update the priorities of frequencies included in the frequency list related to cell selection based on weights set by at least one characteristic of the electronic device (101). As an example, the priority update may include a series of operations for updating the priorities of at least one frequency identified (or selected) based on a search result related to a frequency among the frequencies included in the frequency list related to cell selection based on a sum of the weights.

[0092] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may perform cell selection using a frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101) at operation 307. For example, the processor (200) may sequentially use each frequency based on the priority of the frequencies included in the frequency list related to cell selection to determine whether a cell for camping on exists. For example, camping on may include a series of operations for determining whether a cell to which the electronic device (101) can connect (or register) exists based on at least one of channel state information of a cell using a designated frequency, a list of prohibited cells for registration, or a service provider of the cell.

[0093] For example, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists by using the frequency with the highest priority in the frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) exists by using the frequency with the highest priority, the processor (200) may confirm (or select) the cell as a cell to which the electronic device (101) can connect (or register). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) does not exist by using the frequency with the highest priority, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists by using the frequency with the next priority.

[0094] According to one embodiment, if cell selection using frequencies included in the frequency list related to cell selection fails, the electronic device (101) may perform cell selection again using the frequencies included in the frequency list related to cell selection. For example, if cell selection using frequencies included in the frequency list related to cell selection fails, the processor (200) may control the communication circuit (210) to repeatedly perform cell selection using the frequencies included in the frequency list related to cell selection a specified number of times. If cell selection using frequencies included in the frequency list related to cell selection fails a specified number of times, the processor (200) may control the communication circuit (210) to perform a search (e.g., full scan) related to frequencies (or frequency bands) supported by the electronic device (101). As an example, a failure in cell selection may include a state in which a cell for camping on the electronic device (101) is not detected using the frequencies included in the frequency list related to cell selection.

[0095] FIG. 4 is a flowchart (400) for performing a scan in an electronic device according to one embodiment. For example, at least a portion of FIG. 4 may include detailed operations of operation 301 of FIG. 3 . In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 4 may be the electronic device (101) of FIG. 1 or FIG. 2 .

[0096] According to one embodiment referring to FIG. 4, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2) may, in operation 401, check whether a list of frequencies related to cell selection exists. For example, when the processor (200) detects the occurrence of an event related to cell selection, the processor (200) may check whether a list of frequencies related to cell selection exists in the memory (220). For example, a state in which an event related to cell selection occurs may include at least one of a state in which a communication circuit (210) that was disabled is activated, a state in which the electronic device (101) is determined to have left a shaded area, or a state in which a communication restriction (e.g., airplane mode) of the electronic device (101) is released.

[0097] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, if a list of frequencies related to cell selection exists (e.g., 'yes' in operation 401), perform a search (e.g., power scan) on the list of frequencies related to cell selection in operation 403. For example, if the list of frequencies related to cell selection exists in the memory (220), the processor (200) may check channel state information of each frequency included in the list of frequencies related to cell selection through a search (e.g., power scan) related to at least one frequency included in the list of frequencies related to cell selection. For example, the processor (200) may set priorities of frequencies included in the list of frequencies related to cell selection based on a search result for the list of frequencies related to cell selection.

[0098] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 200)) may perform a search related to frequencies (or frequency bands) supported by the electronic device (101) if a list of frequencies related to cell selection does not exist (e.g., 'No' in operation 401), in operation 405. For example, the processor (200) may control the communication circuit (210) to perform a search (e.g., full scan) related to frequencies (or frequency bands) supported by the electronic device (101) if a list of frequencies related to cell selection does not exist in the memory (220). The processor (200) may perform cell selection based on a result of the search (e.g., full scan) related to frequencies (or frequency bands) supported by the electronic device (101).

[0099] FIG. 5 is a flowchart (500) for updating the priority of a frequency list related to cell selection based on characteristics of the electronic device in an electronic device according to one embodiment. For example, at least a portion of FIG. 5 may include detailed operations of operations 305 and 307 of FIG. 3 . In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 5 may be the electronic device (101) of FIG. 1 or FIG. 2 .

[0100] According to one embodiment referring to FIG. 5, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2) sets priorities of frequencies included in a frequency list related to cell selection based on a search result for a frequency list related to cell selection (e.g., operation 303 of FIG. 3), in operation 501, the processor (200) may update the priorities of the frequencies in the frequency list related to cell selection based on the i-th characteristic of the electronic device (101). For example, the processor (200) may set priorities of frequencies included in a frequency list related to cell selection configured as in Table 1 (e.g., first frequency (A), second frequency (B), third frequency (C), fourth frequency (D), and fifth frequency (E)) as “A→B→C→D→E” based on the search result for the frequency list related to cell selection. For example, "A→B→C→D→E" can indicate a state where frequency A has the highest priority and frequency E has the lowest priority.

[0101] For example, if the electronic device (101) is a VR device (or AR device) that supports reduced capabilities, the processor (200) may identify reduced capabilities, high reliability, high transmission rate, and service area as characteristics of the electronic device (101). The processor (200) may update the priorities of frequencies in the frequency list related to cell selection to “B→D→E→C→A” based on the reduced capabilities among the characteristics of the electronic device (101). For example, if the electronic device (101) supports two receive paths (Rx), the processor (200) may update the priority of the C frequency, which supports reduced capabilities but supports one receive path, to be lower than the B frequency, the D frequency, and the E frequency, which support reduced capabilities and two receive paths. For example, the frequency that supports reduced capabilities and two receive paths may have “cellBarredRedCap2Rx” set to “not barred.” For example, a frequency that supports reduced capability and a single receive path may have "cellBarredRedCap1Rx" set to "not barred." For example, a frequency that does not support reduced capability may have "cellBarredRedCap2Rx" or "cellBarredRedCap1Rx" set to "barred."

[0102] For example, the processor (200) may update the priority of frequency A to the lowest if frequency A does not support reduced capabilities in the frequency list related to cell selection configured as in Table 1. For example, frequency A that does not support reduced capabilities may be deleted from the frequency list related to cell selection.

[0103] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, at operation 503, determine whether there is an additional characteristic that is not used in updating the priority of frequencies included in a frequency list related to cell selection among the characteristics of the electronic device (101). For example, the processor (200) may determine whether there is an unused characteristic in updating the priority of frequencies included in a frequency list related to cell selection among reduced capability, high reliability, high transmission rate, and service area corresponding to a VR device (or AR device) supporting reduced capability.

[0104] According to one embodiment, if there is an additional characteristic that is not used in updating the priority of frequencies included in the frequency list associated with cell selection (e.g., 'Yes' in operation 503), the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 200)) may, in operation 505, identify an additional characteristic to be considered in updating the priority of frequencies included in the frequency list associated with cell selection. For example, the processor (200) may identify characteristics of reduced capability, high reliability, high transmission rate, and high reliability and high transmission rate among service areas corresponding to a VR device (or AR device) supporting reduced capability as additional characteristics.

[0105] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, in operation 501, update the priorities of frequencies in a frequency list related to cell selection based on an additional characteristic (e.g., an i+1-th characteristic) of the electronic device (101). For example, the processor (200) may update the priorities of frequencies in a frequency list related to cell selection to “E→B→D→C→A” based on high reliability and high transmission rate. For example, the processor (200) may update the priority of the E frequency supporting the highest SCS to be the highest.

[0106] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may repeatedly perform operations 501 to 505 until the priorities of the frequencies included in the frequency list related to cell selection are updated, taking into account all the characteristics of the electronic device (101). For example, the processor (200) may update the priorities of the frequencies in the frequency list related to cell selection to “E→D→B→C→A” based on the service area status. For example, the processor (200) may update the priority of the D frequency supporting “intraFreqReselectionRedCap” to be higher than the B frequency not supporting “intraFreqReselectionRedCap”. For example, a state supporting “intraFreqReselectionRedCap” may include a state capable of supporting a relatively wide service area.

[0107] According to one embodiment, if there is no additional characteristic that is not used for updating the priority of frequencies included in the frequency list related to cell selection (e.g., 'No' in operation 503), the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 200)) may perform cell selection using the frequency list related to cell selection whose priorities are updated based on the characteristics of the electronic device (101) in operation 507. For example, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists using the E frequency having the highest priority in the frequency list related to cell selection whose priorities are updated based on the characteristics of the electronic device (101). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) exists using the E frequency, the processor (200) may confirm (or select) the cell as a cell to which the electronic device (101) can connect (or register). If the processor (200) determines that there is no cell for camp on (or a cell suitable for camping on) using the E frequency, the processor (200) can control the communication circuit (210) to check whether there is a cell for camp on (or camping on) using the D frequency of the next priority.

[0108] According to one embodiment, if there is no cell using the E frequency and the D frequency for camping on the electronic device (101), the electronic device (101) may perform cell selection in the order of the B frequency, the C frequency, and the A frequency based on the updated priority of the frequency list related to cell selection.

[0109] According to one embodiment, the electronic device (101) may identify reduced capability and power reduction as characteristics of the electronic device (101) when the electronic device (101) is a stationary sensor (or stationary sensor device) that supports reduced capability. For example, the processor (200) may update the priorities of frequencies in the frequency list related to cell selection to “B→E→C→D→A” based on the reduced capability among the characteristics of the electronic device (101). For example, if frequency A in the frequency list related to cell selection does not support reduced capability, the processor (200) may update the priority of frequency A to the lowest. As an example, frequency A, which does not support reduced capability, may be deleted from the frequency list related to cell selection. For example, if the electronic device (101) supports “halfDuplexRedCap,” the processor (200) may update the priorities of frequency C and frequency D, which do not support “halfDuplexRedCap,” to be relatively low. For example, C and D frequencies that do not support "halfDuplexRedCap" may be removed from the list of frequencies associated with cell selection.

[0110] For example, the processor (200) may update the priority of frequencies in the frequency list related to cell selection to "E→B→C→D→A" based on the status of power consumption. For example, the processor (200) may update the priority of the E frequency, which supports the power consumption function, to be relatively high.

[0111] According to one embodiment, the electronic device (101) may identify the reduced capability, high transmission rate, and service area status as characteristics of the electronic device (101) when the electronic device (101) is a wearable device (e.g., a watch) in a first state that supports reduced capability. For example, the processor (200) may update the priorities of the frequencies in the frequency list related to cell selection to “B→C→D→E→A” based on the reduced capability among the characteristics of the electronic device (101). For example, if frequency A in the frequency list related to cell selection does not support reduced capability, the processor (200) may update the priority of frequency A to be the lowest. As an example, frequency A that does not support reduced capability may be deleted from the frequency list related to cell selection.

[0112] For example, the processor (200) may update the priority of frequencies in the frequency list related to cell selection to "C→D→E→B→A" based on the service area status. For example, the processor (200) may update the priority of frequency B, which does not support "intraFreqReselectionRedCap", to a relatively low priority. For example, a state that supports "intraFreqReselectionRedCap" may include a state that can support a relatively wide service area.

[0113] For example, the processor (200) may update the priority of frequencies in the frequency list related to cell selection to “E→C→D→B→A” based on the status of high data rates (e.g., eMBB). For example, the processor (200) may update the priority of the E frequency, which supports the highest SCS, to the highest.

[0114] According to one embodiment, the electronic device (101) may identify reduced capability, power reduction, and service area status as characteristics of the electronic device (101) when the electronic device (101) is a wearable device (e.g., a watch) in a second state that supports reduced capability. For example, the processor (200) may update the priorities of frequencies in the frequency list related to cell selection to “B→C→D→E→A” based on the reduced capability among the characteristics of the electronic device (101). For example, if frequency A in the frequency list related to cell selection does not support reduced capability, the processor (200) may update the priority of frequency A to be the lowest. As an example, frequency A that does not support reduced capability may be deleted from the frequency list related to cell selection.

[0115] For example, the processor (200) may update the priority of frequencies in the frequency list related to cell selection to "C→D→E→B→A" based on the service area status. For example, the processor (200) may update the priority of frequency B, which does not support "intraFreqReselectionRedCap", to a relatively low priority. For example, a state that supports "intraFreqReselectionRedCap" may include a state that can support a relatively wide service area.

[0116] For example, the processor (200) may update the priority of frequencies in the frequency list related to cell selection to "C→E→D→B→A" based on the state of power reduction. As an example, the processor (200) may update the priority of the E frequency, which supports the power consumption function, to be relatively high.

[0117] FIG. 6 is a flowchart (600) for updating the priority of a frequency list related to cell selection based on characteristics of the electronic device in an electronic device according to one embodiment. For example, at least a portion of FIG. 6 may include detailed operations of operations 305 and 307 of FIG. 3 . In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 6 may be the electronic device (101) of FIG. 1 or FIG. 2 .

[0118] According to one embodiment referring to FIG. 6, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2) sets priorities of frequencies included in a frequency list related to cell selection based on a search result for a frequency list related to cell selection (e.g., operation 303 of FIG. 3), in operation 601, the processor (200) may determine a weight of each frequency included in the frequency list related to cell selection based on an i-th characteristic of the electronic device (101). For example, when the electronic device (101) is a VR device (or AR device) supporting reduced capabilities, the processor (200) may determine reduced capabilities, high reliability, high transmission rate, and service area as characteristics of the electronic device (101).

[0119] For example, the processor (200) may determine a weight corresponding to the reduced capability for each frequency included in the frequency list related to cell selection based on the reduced capability among the characteristics of the electronic device (101). For example, referring to Table 4, if the electronic device (101) supports reduced capability and two receive paths (Rx), the processor (200) may set the weight of the C frequency, which supports reduced capability but supports one receive path, to '1'. The processor (200) may set the weights of the B frequency, the D frequency, and the E frequency, which support reduced capability and two receive paths, to '2'. For example, the processor (200) may set the weight of the A frequency, which does not support reduced capability, to '0'.

[0121] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, at operation 603, determine whether there are additional characteristics that are not used for weight setting among frequencies included in a frequency list related to cell selection among the characteristics of the electronic device (101). For example, the processor (200) may determine whether there are characteristics that are not used for weight setting among frequencies included in a frequency list related to cell selection among reduced capability, high reliability, high transmission rate, and service area corresponding to a VR device (or AR device) supporting reduced capability.

[0122] According to one embodiment, if there is an additional characteristic that is not used in setting weights of frequencies included in the frequency list related to cell selection (e.g., 'Yes' in operation 603), the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 200)) may, in operation 605, identify additional characteristics to be considered in setting weights of frequencies included in the frequency list related to cell selection. For example, the processor (200) may identify characteristics of reduced capability, high reliability, high transmission rate, and high reliability and high transmission rate among service areas corresponding to a VR device (or AR device) supporting reduced capability as additional characteristics.

[0123] In one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, at operation 601, set weights of frequencies in a frequency list associated with cell selection based on an additional characteristic (e.g., an i+1th characteristic) of the electronic device (101). For example, the processor (200) may set the weight of the E frequency supporting the highest SCS to '2'.

[0124] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may repeatedly perform operations 601 to 605 until weights of frequencies included in a frequency list related to cell selection are set, taking into account all characteristics of the electronic device (101). For example, the processor (200) may set a weight of a D frequency that supports "intraFreqReselectionRedCap" to '1' and may set a weight of a B frequency that does not support "intraFreqReselectionRedCap" to '0'.

[0125] According to one embodiment, if the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 200)) determines that the frequencies included in the frequency list associated with cell selection do not have additional characteristics that are not used to set weights (e.g., 'No' in operation 603), then, in operation 607, the processor may update the priorities of the frequencies included in the frequency list associated with cell selection based on the weights set based on the characteristics of the electronic device (101). For example, the processor (200) may update the priorities of the frequencies in the frequency list associated with cell selection to "E→D→B→C→A" based on the weights of each frequency set based on the characteristics of the electronic device (101).

[0126] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may perform cell selection using a frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101) at operation 609. For example, the processor (200) may control the communication circuit (210) to check whether a cell for camp on (or camping on) exists using the E frequency having the highest priority in the frequency list related to cell selection whose priority is updated based on the characteristics of the electronic device (101). If the processor (200) determines that a cell for camp on (or a cell suitable for camping on) exists using the E frequency, the processor (200) may confirm (or select) the cell as a cell to which the electronic device (101) can connect (or register). If the processor (200) determines that there is no cell for camp on (or a cell suitable for camping on) using the E frequency, the processor (200) can control the communication circuit (210) to check whether there is a cell for camp on (or camping on) using the D frequency of the next priority.

[0127] According to one embodiment, the electronic device (101) may perform cell selection in the order of B frequency, C frequency, and A frequency based on the updated priority of the frequency list related to cell selection when there is no cell for camping on the electronic device (101) using the D frequency.

[0128] FIG. 7 is a flowchart (700) for adding at least one frequency to a frequency list related to cell selection in an electronic device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 7 may be the electronic device (101) of FIG. 1 or FIG. 2 .

[0129] According to one embodiment referring to FIG. 7, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or processor (200) of FIG. 2) may perform cell selection in operation 701. For example, the processor (200) may control the communication circuit (210) to perform cell selection based on priorities of frequencies included in a frequency list related to updated cell selection based on characteristics of the electronic device (101), such as operations 301 to 307 of FIG. 3.

[0130] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, at operation 703, determine additional frequency information from a selected cell based on an updated priority based on characteristics of the electronic device (101). For example, if the electronic device (101) supports reduced capability, the processor (200) may determine additional frequency information supporting reduced capability from the "redCapAccessAllowed" information of the "interFrequCarrierFreqInfo" field of SIB 4. For example, the additional frequency information may include information related to a frequency (e.g., inter frequency) of a neighboring cell that is different from the frequency of a cell to which the selected electronic device (101) can access by using a frequency list related to cell selection.

[0131] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 200)) may, at operation 705, update a frequency list associated with cell selection based on additional frequency information. For example, the processor (200) may add the additional frequency information to the frequency list associated with cell selection. For example, the additional frequency information (e.g., F frequency, G frequency, and H frequency) may be added to the frequency list associated with cell selection with a relatively low priority, as shown in Table 5.
