According to one embodiment, the base station 100 or the electronic device 110 may be controlled by one media access control (MAC) layer block to perform communications using two carriers 121 and 123 Two physical layer blocks may be controlled. According to one embodiment, the base station 100 or the electronic device 110 may be configured to communicate with two physical layer blocks (not shown) by each of two MAC layer blocks, Each can be controlled.

Here, one of the two carriers 121 and 123 is referred to as a primary carrier (e.g., a first carrier 121) and the other is referred to as a secondary carrier (e.g., a second carrier 1231) . According to one embodiment, one physical layer block may be included in one communication module. The present invention is not limited thereto, and according to one embodiment, a plurality of physical layer blocks may be included in one communication module.

In various embodiments of the present invention, two carriers 121 and 123 for a carrier aggregation scheme may be provided by multiple base stations. For example, the electronic device 110 may perform communication on a first carrier 121 for the base station 100 and a second carrier 123 for another base station on a carrier-integrated basis.

In various embodiments of the present invention, the base station 100 and the electronic device 110 may selectively use a carrier aggregation scheme for the uplink based on channel conditions. In one embodiment, the base station 100 may be configured to selectively use the carrier aggregation scheme for the uplink based on either the downlink channel state information or the uplink channel state information with the electronic device 110, Can be controlled. In one embodiment, the electronic device 110 may selectively use a carrier aggregation scheme for the uplink based on either the downlink channel state information or the uplink channel state information with the base station 100.

That is, when the intensity of the received signal is small, the electronic device 210 can determine that the distance from the base station 200 increases.

2 (b), the electronic device 210 increases the strength of the signal transmitted to the base station 200 as the intensity of the received signal decreases (the distance from the base station 200 increases) (230). For example, the electronic device 210 may estimate the distance to the base station 200 based on the strength of the received signal. The electronic device 210 can determine the transmission power of the signal to correspond to the distance from the base station 200. [ For example, the electronic device 210 may estimate the distance to the base station 200 as a first distance if the strength of the received signal is a first intensity. Accordingly, the electronic device 210 may transmit the signal to the base station 200 at the first transmission power. The electronic device 210 may estimate the distance from the base station 200 to a second distance shorter than the first distance when the intensity of the received signal is a second intensity greater than the first intensity. Thus, the electronic device 210 may transmit a signal to the base station 200 with a second transmit power that is less than the first transmit power.

According to one embodiment, the electronic device 210 may transmit data (signal) to the base station 200 through a carrier wave integration scheme. The electronic device 210 may transmit data at a higher transmit power than the reference transmit power 240 through each communication module (e.g., an RF module) corresponding to each of the plurality of carriers to correspond to the received signal strength. In this case, the electronic device 210 can generate electromagnetic waves exceeding the electromagnetic wave absorption rate standard. Accordingly, when it is determined that the electronic device 210 should transmit data with a transmission power higher than the reference transmission power 240 on the basis of the received signal strength, the electronic device 210 corresponds to one carrier for communication among a plurality of carriers The communication module can be deactivated. That is, the electronic device 210 can cancel the carrier integration method used for data transmission.

The following description is directed to operations 701 to 707 for controlling the carrier aggregation scheme for the uplink in the processor 320 or the communication control module 330 of the base station 301 (or electronic device) Explain.

Referring to FIG. 7, at operation 701, a base station (e.g., processor 320 or communications control module 330) may communicate with an electronic device using a carrier aggregation scheme (e.g., using multiple carriers) . For example, the communication control module 330 may control the communication interface 350 (e.g., a transmitter, a transceiver, or a modem) to transmit and receive data to and from an electronic device connected to the base station 301 via a plurality of carriers .

In operation 703, the base station may receive channel state information for a plurality of carriers from the electronic device. For example, the communication control module 330 (e.g., a communications processor) may send a list of required channel conditions for controlling the carrier aggregation scheme to the electronic device via the communication interface 350. The communication control module 330 receives channel state information for each carrier corresponding to a required channel state list for controlling the carrier aggregation scheme on each carrier wave (e.g., intensity of a signal received from the base station, quality of a channel, NACK Occurrence information, or information related to a combination thereof). For example, the communication control module 330 may receive channel state information corresponding to a necessary channel state list for controlling a carrier aggregation scheme through a selected one of a plurality of carriers (e.g., a main carrier). In this case, the channel state information may include an average of channel states of a plurality of carriers. For example, the channel state information may include at least one of a received signal strength of a downlink channel, a quality of a downlink channel, and NACK generation information of an uplink channel.

At operation 705, the base station may determine whether to release the carrier aggregation scheme based on channel state information provided from the electronic device. For example, the communication control module 330 may determine whether the electronic device is located in the weak electric field area based on the channel state information provided from the electronic device. For example, when the communication control module 330 receives the channel state information for each carrier, the communication control module 330 may determine whether the electronic device is located in the weak electric field area based on an average of channel states of the carriers. For example, when the channel state information for each carrier is received, the communication control module 330 determines whether the electronic device is located in the weak electric field area based on the number of carriers for which the channel state satisfies the cancellation criterion of the carrier- can do. When the communication control module 330 determines that the electronic device is located in the weak electric field area, the communication control module 330 can determine to cancel the carrier integration method for the uplink.

If the base station determines to maintain the carrier aggregation scheme for the electronic device, then at operation 701, it may communicate with the electronic device using the carrier aggregation scheme. For example, the communication control module 330 may control the communication interface 350 to receive uplink data from an electronic device connected to the base station 301 via a plurality of carriers. For example, the communication control module 330 may control the communication interface 350 to transmit the setting signal of the carrier-integrated method to the electronic device. Accordingly, the communication control module 330 can receive uplink data from the electronic device through a plurality of carriers.

In operation 707, if the base station determines to release the carrier aggregation scheme for the electronic device, it may transmit the carrier aggregation scheme deactivation signal to the electronic device. For example, the communication control module 330 may control the communication interface 350 to transmit a carrier-freeing signal to an electronic device via at least one of the plurality of carriers. For example, the communication control module 330 may select a main carrier that has transmitted a carrier-freeing signal based on channel conditions of a plurality of carriers. For example, the communication control module 330 may select a main carrier that has transmitted a carrier-freeing signal based on the priorities of a plurality of carriers.

In various embodiments of the invention, the base station may maintain communication with the electronic device over a carrier selected by the electronic device of the plurality of carriers when the base station determines to release the carrier aggregation scheme. For example, the communication control module 330 may control the communication interface 350 to transmit a carrier-freeing signal to an electronic device via any one of a plurality of carriers assigned to the electronic device. The communication control module 330 may determine that the carrier wave of the response signal to the carrier aggregation cancel signal among the plurality of carriers is the main carrier selected by the electronic device. For example, when the communication control module 330 receives a response signal to the carrier aggregation cancel signal through the communication interface 350, the communication control module 330 can confirm the main carrier information included in the response signal.

In operation 903, the base station compares the channel quality of the downlink channel with the reference channel quality to determine whether the channel quality of the downlink channel is less than the reference channel quality. Here, the reference channel quality may include a predetermined channel quality for determining whether the electronic device is located in the weak electric field area to determine whether to release the carrier aggregation scheme for the uplink.

In operation 905, the base station may determine that the electronic device is located in the weak electric field area when the channel quality of the downlink channel is smaller than the reference channel quality. Accordingly, the base station can decide to release the carrier aggregation scheme for the electronic device. For example, if the communication control module 330 determines that the electronic device is located in the weak electric field area, it may decide to release the carrier integration method for the uplink of the electronic device.

Referring to FIG. 10, in operation 1001, a base station (e.g., processor 320 or communication control module 330) may detect NACK generation information of an uplink channel from channel state information provided from an electronic device. For example, the NACK occurrence information may include a number of occurrences of a NACK or a rate of occurrence of a NACK of an uplink channel detected by an electronic device during a reference time.

In operation 1003, the BS compares the NACK occurrence information of the uplink channel with the reference NACK occurrence number to determine whether the NACK occurrence frequency of the uplink channel is larger than the reference NACK occurrence frequency. Here, the frequency of occurrence of the reference NACK may include a predetermined number of NACK occurrences for determining whether the electronic device is located in the weak electric field area to determine whether to release the carrier aggregation scheme for the uplink.

In operation 1005, if the frequency of occurrence of the NACK of the uplink channel is greater than the frequency of occurrence of the reference NACK, the base station can decide to release the carrier aggregation scheme for the electronic device. For example, if the frequency of occurrence of NACK of the uplink channel is greater than the frequency of occurrence of the reference NACK, the communication control module 330 may determine that the quality of the uplink channel is degraded because the electronic device is located in the weak electric field area. Accordingly, the communication control module 330 can decide to release the carrier integration method for the uplink of the electronic device. According to one embodiment, if the base station determines to release the carrier aggregation scheme for the uplink of the electronic device, it may transmit the carrier aggregation cancellation signal to the electronic device (e.g., operation 707 of FIG. 7).

The base station can determine that the electronic device is located in the strong or medium power system region when the frequency of occurrence of the NACK of the uplink channel is less than or equal to the frequency of occurrence of the reference NACK. Accordingly, the base station can perform communication with the electronic device using the carrier wave integration method at operation 701 of FIG. According to one embodiment, when the base station determines to perform communication with an electronic device using a carrier aggregation scheme, the base station can transmit a carrier aggregation scheme setting signal to the electronic device.

For example, the communication control module 480 may control the communication interface 470 to allow the electronic device 401 to transmit and receive data with the base station 402 via respective communication modules corresponding to a plurality of carriers.

In operation 1103, the electronic device can estimate the status information of the channel that transmits and receives data with the network constituent device. For example, the communication control module 480 may estimate channel state information for each carrier allocated from the base station. For example, the communication control module 480 may calculate an average of channel state information of a plurality of carriers allocated from the base station. For example, the communication control module 480 may estimate the channel state information corresponding to the channel state list provided from the base station. The channel state information may include at least one of a received signal strength of a downlink channel, a quality of a downlink channel, and NACK generation information of an uplink channel.

In operation 1105, the electronic device may transmit the channel state information estimated in operation 1103 to the network constituent device.

For example, the electronic device may transmit data to the base station 402 using a plurality of carriers (e.g., two carriers).

In operation 1109, when the electronic device receives the carrier aggregation cancellation signal from the network constituent device, it can release the carrier aggregation scheme. For example, the communication control module 480 may determine that the carrier that received the carrier aggregation cancellation signal is a main carrier selected by the base station. The communication control module 480 may control the communication interface 470 to transmit and receive data to and from the base station 402 via the main carrier. For example, the communication control module 480 may select one carrier for communication with the base station 402 based on channel state information of a plurality of carriers for a carrier aggregation scheme.

For example, the communication control module 480 may control the communication interface 470 to transmit the selected carrier information for communication with the base station 402 to the base station 402. For example, the communication control module 480 may select one communication module to communicate with the base station 402 based on the priority of the communication modules included in the communication interface 470. The communication interface 470 may be controlled to transmit and receive data to and from the base station 402 using one communication module for communicating the communication control module 480 with the base station 402. The communication control module 480 may control the communication interface 470 to deactivate the remaining communication modules. For example, the communication control module 480 may control the communication interface 470 to transmit carrier information corresponding to the selected communication module for communication with the base station 402 to the base station 402.

For example, in the case of FIG. 1, the base station 100 can transmit and receive data to and from the electronic device 110 connected to the base station 100 through a plurality of carriers 121 and 123.

In operation 1403, the base station may detect channel state information of the uplink channel receiving data from the electronic device. For example, the communication control module 330 may estimate the channel state of the uplink channel for each carrier allocated to the electronic device. For example, the communication control module 330 may calculate an average of channel state information of a plurality of carriers allocated to the electronic device. For example, the channel state information of the uplink channel may include at least one of the received signal strength of the uplink channel, the quality of the uplink channel, and the NACK generation information of the uplink channel.

In operation 1405, the base station may determine whether to release the carrier aggregation scheme based on the channel state information of the uplink channel. For example, the communication control module 330 may determine whether the electronic device is located in the weak electric field area based on the channel state information of the uplink channel. For example, the communication control module 330 may determine whether the electronic device is located in the weak electric field area based on an average of the number of carriers satisfying the canceling criterion of the carrier aggregation type or the channel state of the carriers.

If the base station determines to maintain the carrier aggregation scheme for the electronic device, at operation 1401, it may transmit and receive data with the electronic device using the carrier aggregation scheme. For example, the communication control module 330 may control the communication interface 350 to receive uplink data from an electronic device connected to the base station 301 via a plurality of carriers. For example, if the base station determines to maintain a carrier aggregation scheme for an electronic device, then in operation 1401, the base station may transmit a carrier aggregation scheme establishment signal to the electronic device.

In operation 1407, if the base station determines to release the carrier aggregation scheme for the electronic device, it may transmit the carrier aggregation cancellation signal to the electronic device. For example, the communication control module 330 may select a carrier to communicate with the electronic device based on the channel state or priority of the carriers. The communication control module 330 may control the communication interface 350 to transmit a carrier-freeing cancellation signal to the electronic device via the carrier selected for communication with the electronic device. For example, the communication control module 330 may control the communication interface 350 to transmit a carrier-freeing cancellation signal to an electronic device via any of a plurality of carriers.

FIG. 15 is a flowchart illustrating a method for determining whether to release a carrier aggregation scheme based on signal strength of an uplink channel in a network configuration apparatus according to various embodiments of the present invention. The following description is directed to an operation for determining whether to release the carrier aggregation scheme at the operation 3205 of the base station 301 or the communication control module 330 at the operation 1405 of Fig.

Referring to FIG. 15, in operation 1501, a base station (e.g., processor 320 or communication control module 330) may verify that an uplink signal (data) is received from an electronic device via a plurality of carriers. For example, the communication control module 330 can confirm whether uplink data is received through each communication module (RF module) included in the communication interface 350.

In operation 1503, when the uplink signal (data) is received, the base station can detect the signal strength of the uplink channel. For example, the communication control module 330 may measure the signal strength of the uplink channel corresponding to each carrier allocated to the electronic device. The communication control module 330 may calculate an average of signal strengths of uplink channels corresponding to the carriers allocated to the electronic device. For example, the received signal strength may include at least one of RSSI, RSRP, and SINR.

In operation 1505, the base station compares the signal strength of the uplink channel with the reference signal strength to confirm whether the signal strength of the uplink channel is smaller than the reference signal strength. Here, the reference signal strength may include a predetermined signal strength to determine whether the electronic device for determining whether to release the carrier aggregation scheme for the uplink is located in the weak electric field area.

In operation 1507, if the signal strength of the uplink channel is less than the reference signal strength, the base station can decide to release the carrier aggregation scheme for the electronic device. For example, when the signal strength of the uplink channel is less than the reference signal strength and the electronic device determines that the electronic device is located in the weak electric field area, the communication control module 330 cancels the carrier integration method for the uplink of the electronic device You can decide. According to one embodiment, if the base station determines to release the carrier aggregation scheme for the uplink of the electronic device, it may transmit the carrier aggregation cancellation signal to the electronic device (e.g., operation 1407 in FIG. 14).

The base station can determine that the electronic device is not located in the weak electric field area when the signal strength of the uplink channel is equal to or greater than the reference signal strength. Accordingly, the base station can perform communication with the electronic device using the carrier wave integration method at operation 1401 in Fig. According to one embodiment, when the base station determines to perform communication with an electronic device using a carrier aggregation scheme, the base station can transmit a carrier aggregation scheme setting signal to the electronic device.

For example, the communication control module 330 may determine that the electronic device is located in the weak electric field area when the number of carriers whose signal strength of the uplink channel is smaller than the reference signal intensity exceeds the reference number. Accordingly, the communication control module 330 can decide to release the carrier integration method for the uplink of the electronic device.

For example, the communication control module 330 can check whether data received through the communication interface 350 has an error.

In operation 1603, when a NACK for the uplink channel occurs, the base station can confirm the number of NACKs for the uplink channel. For example, the communication control module 330 can confirm the number of NACK occurrences of the uplink channel occurring during the reference time. That is, the communication control module 330 can check the frequency of NACK occurrence for the uplink channel.

In operation 1605, the base station can check whether the frequency of occurrence of the NACK of the uplink channel is larger than the frequency of occurrence of the reference NACK by comparing the number of occurrences of the NACK of the uplink channel with the number of occurrences of the reference NACK. Here, the frequency of occurrence of the reference NACK may be changed to correspond to the channel environment.

In operation 1607, if the frequency of occurrence of the NACK of the uplink channel is larger than the frequency of occurrence of the reference NACK, the base station can decide to release the carrier aggregation scheme for the electronic device. For example, the communication control module 330 may determine that the electronic device is located in the weak electric field area when the frequency of occurrence of the NACK of the uplink channel is larger than the frequency of occurrence of the reference NACK. Accordingly, the communication control module 330 can decide to release the carrier integration method for the uplink of the electronic device. According to one embodiment, if the base station determines to release the carrier aggregation scheme for the uplink of the electronic device, it may transmit the carrier aggregation cancellation signal to the electronic device (e.g., operation 1407 in FIG. 14).

The base station can determine that the electronic device is located in the strong or medium power system region when the frequency of occurrence of the NACK of the uplink channel is less than or equal to the frequency of occurrence of the reference NACK. Accordingly, the base station can perform communication with the electronic device using the carrier wave integration method at operation 1401 in Fig. According to one embodiment, when the base station determines to perform communication with an electronic device using a carrier aggregation scheme, the base station can transmit a carrier aggregation scheme setting signal to the electronic device.

For example, the communication control module 480 may measure at least one of a received signal strength of a downlink channel and a quality of a downlink channel based on a signal received from a base station through a plurality of carriers. For example, the communication control module 480 can detect NACK generation information of an uplink channel through which data is transmitted from a base station through a plurality of carriers.

[ When the communication control module 480 satisfies the cancellation criterion of the carrier aggregation method provided from the base station 402, it can be determined that the carrier aggregation scheme is canceled. For example, the communication control module 480 can confirm whether the signal strength of the downlink channel is smaller than the reference signal strength. For example, the communication control module 480 can check whether the channel quality of the downlink channel is smaller than the reference channel quality. For example, the communication control module 480 can check whether the number of times the NACK of the uplink channel is generated exceeds the number of times the reference NACK occurs.

For example, the communication control module 480 can check whether the channel quality of the downlink channel is smaller than the reference channel quality. For example, the communication control module 480 can check whether the number of NACK occurrences of the uplink channel exceeds the number of reference NACK occurrences. For example, the communication control module 480 may check whether the NACK occurrence rate of the uplink channel corresponding to the carriers allocated for the carrier aggregation method exceeds the reference NACK occurrence rate.

If the channel state information of the carriers does not satisfy the cancellation criterion of the carrier aggregation method, the electronic device can transmit and receive data to and from the network constituent device (base station) through a plurality of carriers in accordance with the carrier aggregation scheme in operation 2101 of FIG. have.

The following description explains the operation for setting the carrier aggregation method in the processor 320 or the communication control module 330 of the base station 301 shown in FIG.

Referring to FIG. 23, at operation 2301, a base station (e.g., processor 320 or communications control module 330) may receive channel state information from an electronic device connected to the base station. For example, if the communication control module 330 determines that the electronic device is located in the weak electric field area based on the channel state information of the electronic device, the communication control module 330 may cancel the carrier integration method for the uplink of the electronic device. That is, the communication control module 330 can release the connection with the electronic device by using the carrier wave excluding the main carrier among the plurality of carriers allocated to the electronic device for the carrier wave integration method. The communication control module 330 may receive channel state information from the electronic device via the main carrier. For example, the channel state information may include at least one of a received signal strength of a downlink channel, a quality of a downlink channel, and NACK generation information of an uplink channel.

In operation 2303, the base station can confirm whether the channel status information provided from the electronic device satisfies the setting criterion of the carrier aggregation scheme. For example, the communication control module 480 can check whether the signal strength of the downlink channel is equal to or greater than the reference signal strength. The communication control module 480 can determine that the signal strength of the downlink channel is greater than or equal to the reference signal strength and that the criterion for setting the carrier aggregation method is satisfied. For example, the communication control module 480 can check whether the channel quality of the downlink channel is greater than or equal to the reference channel quality. The communication control module 480 can determine that the channel quality of the downlink channel is equal to or greater than the reference channel quality and that the criteria for setting the carrier aggregation method is satisfied. For example, the communication control module 480 may determine whether the number of NACKs generated in the uplink channel is less than or equal to the number of times the reference NACK occurs. The communication control module 480 can determine that the set criteria of the carrier aggregation scheme is satisfied when the number of NACK generations of the uplink channel is equal to or less than the number of times of occurrence of the reference NACK. For example, the communication control module 480 may check whether the NACK generation rate of the uplink channel corresponding to the carriers allocated for the carrier aggregation scheme is less than the reference NACK occurrence rate. The communication control module 480 may determine that the NACK generation rate of the uplink channel is less than the reference NACK occurrence rate and satisfies the setting criteria of the carrier aggregation scheme.

The base station may again receive channel state information from the electronic device, at operation 2301, if the channel state information of the electronic device does not meet the set criteria of the carrier wave integration scheme.

In operation 2305, the base station may transmit a carrier accumulation type setting signal to the electronic device when the channel status information of the electronic device satisfies the setting criterion of the carrier aggregation scheme. For example, if the channel state information of the electronic device satisfies the setting criterion of the carrier wave integration method, the communication control module 330 may determine that the electronic device has moved out of the weak electric field area and moved to the middle or strong electric field area have. Accordingly, the communication control module 330 can control the communication interface 350 to transmit the carrier-integrated setting signal to the electronic device via the main carrier.

At operation 2307, the base station can establish communications for the carrier aggregation scheme with the electronic device. For example, the communication control module 330 may further allocate a carrier to an electronic device for a carrier aggregation scheme.

In various embodiments of the present invention, the reference information for releasing the carrier aggregation scheme and the reference information for setting the carrier aggregation scheme may be the same or different. For example, when the reference information for setting or canceling the carrier aggregation scheme is different, the reference signal strength for setting the carrier aggregation scheme may be set to a value larger than the reference signal strength for canceling the carrier aggregation scheme. For example, when the reference information for setting or canceling the carrier aggregation scheme is different, the reference signal quality for setting the carrier aggregation scheme may be set to a value higher than the reference signal quality for canceling the carrier aggregation scheme. For example, when the reference information for setting or releasing the carrier aggregation scheme is different, the number of reference NACK generations for setting the carrier aggregation scheme may be set to a value smaller than the number of reference NAKC generations for releasing the carrier aggregation scheme .

For example, the second transmitter 3036 and the second receiver 3038 may be logically or physically separated.

According to one embodiment, the transceiver 3030 may be coupled to any one of the first transmitter 3032 or the second transmitter 3036, which corresponds to the carrier selected to transmit data to the base station, 3032 or 3034). In this case, the remaining transmitters 3034 or 3032 may be deactivated.

According to one embodiment, the transceiver 3030 activates the first transmitter 3032 and the second transmitter 3036 to transmit data to the base station via the first carrier and the second carrier when the carrier aggregation scheme is set . For example, transceiver 3030 may be enabled or disabled by first modem 3012 or second modem 3014 or another separate processor.

According to one embodiment, the first power amplifier 3040 can amplify the power of a signal (e.g., an RF signal) provided from the first transmitter 3032 in accordance with the characteristics of the first carrier. The second power amplifier 3042 may amplify the power of a signal (e.g., an RF signal) provided from the second transmitter 3036 in accordance with the characteristics of the second carrier.

According to one embodiment, when the carrier aggregation scheme is canceled, the first power amplifier 3040 and the second power amplifier 3042 can be activated only one corresponding to a carrier selected for transmitting data to the base station. In this case, the remaining power amplifier 3042 or 3040 may be deactivated. For example, the electronic device 3000 can supply power to the activated power amplifier 3040 or 3042 and shut off the power supply to the inactivated power amplifier 3042 or 3040.

According to one embodiment, the first power amplifier 3040 and the second power amplifier 3042 can be all activated to transmit data to the base station through the first carrier and the second carrier when the carrier aggregation scheme is set . For example, the first power amplifier 3040 and the second power amplifier 3042 may be activated or deactivated by the first modem 3012 or the second modem 3014 or another separate processor.

For example, the first duplexer 3050 may connect the first transmitter 3032 or the first receiver 3034 with the first antenna 3060 to correspond to a transmission / reception mode of data through the first carrier. For example, the first duplexer 3050 transmits the data received through the first carrier to the first receiver 3034 and the data received from the first transmitter 3032 through the first power amplifier 3040 To the first antenna 3060.

For example, the second duplexer 3052 can couple the second antenna 3062 and the second transmitter 3036 or the second receiver 3038 to correspond to the transmission / reception mode of data through the second carrier. For example, the second duplexer 3052 transmits the data received through the second carrier to the second receiver 3038 and the data received from the second transmitter 3036 through the second power amplifier 3042 To the second antenna 3062.
