COMMUNICATION METHOD AND APPARATUS THEREOF

TECHNICAL FIELD

BACKGROUND

In a wireless communication, user equipment (UE) communicate with network devices, that implement the network. With the development of radio frequency interference cancellation technology and digital domain interference cancellation technology, in some scenarios, co-frequency co-time full duplex technology may be used on a network device side.

In this scenario, the network device may use the same time and frequency to transmit and receive, which causes mutual interference between a plurality of user equipment in the same cell or adjacent cells. Avoiding mutual interference between a plurality of user equipment is a problem that needs to be addressed.

The embodiments shall not be construed to limit the present disclosure.

FIG. 1 is a schematic flowchart of a communication method provided by an embodiment of the present disclosure. It is noted that the communication method in embodiments of the present disclosure is applied to a network device.

As shown in FIG. 1, the communication method includes the following steps.

In step 101, a measurement bandwidth and a subband of a carrier are configured, and it is communicated with a user equipment (UE) via the subband.

For example, the network device may be a base station; or a user equipment (UE), such as a UE covered by a base station.

The UE may refer to a device that provides voice and/or data connectivity to users. The UE may communicate with one or more core networks via radio access network (RAN). The UE may be a user equipment of an Internet of Things (IoT), such as a sensor device, a mobile phone (or called a cellular phone) and computers with IoT user equipment. For example, the user equipment may be fixed, portable, pocket, hand-held, computer built-in or vehicle-mounted devices. For example, the user equipment may be a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the UE may also be equipment of an unmanned aerial vehicle. Alternatively, the UE may also be a vehicle-mounted device, for example, a trip computer with a wireless communication function, or a wireless user equipment connected externally to the trip computer. Alternatively, the UE may also be a roadside device, for example, may be a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

It is noted that in embodiments of the present disclosure, the UE communicating with the network device may be a single UE in a cell covered by the network device, a group of UEs in a cell covered by the network device, or all UEs in a cell covered by the network device, which is not limited in embodiments of the present disclosure. Each embodiment of the present disclosure is explained by taking all UEs as examples.

The subband is a continuous frequency band that contains one or more physical resource blocks (PRBs). The physical resource block is a frequency domain unit and consists of continuous subcarriers.

In an illustrative embodiment, the network device may configure the measurement bandwidth of the carrier and divide the measurement bandwidth into a plurality of subbands, and may configure the UE corresponding to each subband and a subband type of each subband, and then communicate with each UE separately. The subband corresponding to the UE refers to the subband configured by the network device, and used when communicating with the UE.

The types of the subbands include an uplink type, a downlink type and a flexible type.

In one embodiment of the present disclosure, when the types of the subbands corresponding to the UE are different, ways in which the network device communicates with the UE via the subband are also different.

When the type of the subband is the downlink type, the network device may transmit data to the UE on the subband. When the type of the subband is the uplink type, the network device may receive data transmitted by the UE on the subband. When the type of the subband is the flexible type, the network device may configure the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling. In one embodiment of the present disclosure, the network device may specifically configure the flexible type of the subband as the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling, so that when the UE determines that the type of the subband corresponding to itself is the flexible type, it may determine whether the subband is used for the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling.

In one embodiment of the present disclosure, when the flexible type subband is configured as null, the network device does not perform any operation on the subband.

It is noted that the network device may configure each subband to correspond to one UE, or it may also configure a plurality of subbands to correspond to one UE, which is not limited in the present disclosure. In addition, when the same UE corresponds to a plurality of subbands, the types of each subband may be the same or different, which is not limited in the present disclosure.

In step 102, a measurement value of the subband fed back by the UE is received.

In an illustrative embodiment, each UE may measure communication quality for the communication with the network device via the corresponding subband, generate the measurement value for the subband, and feed back the measurement value of the subband to the network device. The measurement value of the subband may reflect an interference level when the UE communicates with the network device via the subband.

It is noted that for the same UE, when the UE corresponds to one subband, the UE feeds back to the network device the measurement value of the subband corresponding to the UE. When the UE corresponds to a plurality of subbands, the UE feeds back to the network device the measurement value for each subband corresponding to the UE.

In one embodiment of the present disclosure, each UE may only measure communication quality of the subband with the downlink type corresponding to the UE, and generate a measurement value of the subband with the downlink type, and feedback the measurement value of the subband with the downlink type to the network device.

In step 103, subband configuration corresponding to the carrier is adjusted according to the measurement value of the subband.

In an illustrative embodiment, after receiving the measurement value of the corresponding subband fed back by each UE, the network device may adjust the subband configuration corresponding to the carrier according to the measurement value of the subband. Specifically, the network device may adjust the types of the plurality of the subbands in the carrier and the UEs corresponding to the plurality of the subbands.

For example, assume that a type of subband 1 corresponding to a user equipment A (UE-A) configured by the network device is the uplink type, a type of subband 2 corresponding to a user equipment B (UE-B) is the downlink type, and a distance between UE-A and UE-B is relatively close. Assume that after the network device communicates with UE-A and UE-B respectively via the corresponding subbands, UE-B feeds back to the network device the measurement value for subband 2 with the downlink type, and the measurement value for subband 2, which reflects that a communication process between UE-B and the network device is interfered by UE-A, then the network device may, for example, adjust the subband configuration corresponding to the carrier as follows: unify the types of subbands corresponding to UE-A and UE-B respectively, for example, adjust the type of subband 1 corresponding to UE-A to the downlink type, or adjust the type of subband 2 corresponding to UE-B to the uplink type. Alternatively, the network device may add a subband with a null type between the subbands corresponding to UE-A and UE-B respectively to isolate the communication between UE-A and the network device and the communication between UE-B and the network device.

In this way, when there is mutual interference between uplink and downlink services in UEs, the network device may reasonably adjust the subband configuration corresponding to the carrier based on the subband measurement values fed back by the UE, so as to avoid interference between the UE and the network device when communicating with the network device.

In summary, the network device configures the measurement bandwidth and the subband of the carrier, communicates with the user equipment (UE) via the subband, receives the measurement value of the subband fed back by the UE, and adjusts the subband configuration corresponding to the carrier according to the measurement value of the subband, which realizes reasonable adjustment of the subband configuration corresponding to the carrier according to the subband measurement values fed back by the UE, thus avoiding the problem of mutual interference between the plurality of UEs.

Embodiments of the present disclosure provides another communication method. FIG. 2 is a schematic flowchart of another communication method provided by an embodiment of the present disclosure. The communication method may be applied to a network device. The communication method may be executed alone or in combination. Any embodiment or possible implementation in embodiments of the present disclosure may be executed together, or may be executed in combination with any technical solution in related art.

As shown in FIG. 2, the communication method may include the following steps.

In step 201, a measurement bandwidth and a subband of the carrier are configured, subband configuration is sent to the UE via a configuration signaling, and the network device communicates with a user equipment (UE) via the subbands.

In an illustrative embodiment, the network device may configure the measurement bandwidth of the carrier and divide the measurement bandwidth into a plurality of subbands, and may configure the UE corresponding to each subband and a subband type of each subband, and send subband configuration to the UE via the configuration signaling., thereby communicating with each UE via the configured subbands corresponding to each UE.

The subband configuration is used to configure the types of the plurality of subbands in the carrier. The types of subband include an uplink types, a downlink types and a flexible types. When the type of the subband is the downlink type, the network device may transmit data to the UE on the subband. When the type of the subband is the uplink type, the network device may receive data transmitted by the UE on the subband. When the type of the subband is the flexible type, the network device may configure the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling. In one embodiment of the present disclosure, the network device may specifically configure the flexible type of the subband as the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling, so that when the UE determines that the type of the subband corresponding to itself is the flexible type, it may determine whether the subband is used for the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling.

In an illustrative embodiment, the network device may send the subband configuration to a single UE, a group of UEs, or all UEs covered by the network device via the configuration signaling. The configuration signaling may be, for example, a radio resource control (RRC) common signaling, a RRC dedicated signaling, or a downlink control information (DCI) signaling.

In step 202, a measurement value of the subband fed back by the UE is received.

In an illustrative embodiment, the measurement value of the subband includes one or more of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indication (RSSI), or a signal-to-noise and interference ratio (SINR).

For detailed introduction to step 202, reference may be made to the relevant introduction in the above embodiments, and embodiments of the present disclosure will not be repeated here.

In step 203, subband configuration corresponding to the carrier is adjusted according to the measurement value of the subband.

In an illustrative embodiment, after receiving the measurement value of the corresponding subband fed back by each UE, the network device may adjust the subband configuration corresponding to the carrier according to the measurement value of the subband. Specifically, the network device may adjust the types of the plurality of the subbands in the carrier and the sequence numbers of the subbands corresponding to each UE, etc.

For example, assume that a type of subband 1 corresponding to UE-A configured by the network device is the uplink type, a type of subband 2 corresponding to UE-B is the downlink type, and a distance between UE-A and UE-B is relatively close. Assume that after the network device communicates with UE-A and UE-B respectively via the corresponding subbands, UE-B feeds back to the network device the measurement value for subband 2 with the downlink type, and the measurement value for subband 2 reflects that there is interference between UE-A and UE-B in a communication process with the network device, then the network device may, for example, adjust the subband configuration corresponding to the carrier as follows: unify the types of subbands corresponding to UE-A and UE-B respectively, for example, adjust the type of subband 1 corresponding to UE-A to the downlink type, or adjust the type of subband 2 corresponding to UE-B to the uplink type. Alternatively, the network device may maintain the uplink type of subband 1 unchanged, configure subband 2 as null, and configure subband 3 to correspond to UE-B, so as to isolate communication between UE-A and the network device and communication between UE-B and the network device.

In step 204, the subband configuration adjusted is sent to the UE.

In an illustrative embodiment, after the network device adjusts the subband configuration corresponding to the carrier according to the measurement value of the subband, the network device may also send the adjusted subband configuration to each UE, so that each UE may determine the corresponding subband and the type of the subband after adjusting the subband configuration, so as to enable the network device and each UE to communicate with each UE via the subband after adjusting the subband configuration. Specifically, the network device may send the adjusted subband configuration to the UE via the configuration signaling. For a specific process of sending the adjusted subband configuration to the UE, reference may be made to the above process of sending the subband configuration to the UE, which will not be described again here.

In summary, the network device configures the measurement bandwidth and the subband of the carrier, sends the subband configuration to the UE via the configuration signaling, communicates with the user equipment (UE) via the subband, receives the measurement value of the subband fed back by the UE, adjusts the subband configuration corresponding to the carrier according to the measurement value of the subband, and sends the adjusted subband configuration to the UE, which realizes that the network device reasonably adjusts the subband configuration corresponding to the carrier according to the measurement value of the subband fed back by the UE, thereby avoiding the problem of mutual interference between a plurality of UEs.

Embodiment of the present disclosure provide another communication method. FIG. 3 is a schematic flowchart of another communication method provided by an embodiment of the present disclosure. The communication method may be applied to a network device. The communication method may be executed alone or in combination. Any embodiment or possible implementation in embodiments of the present disclosure may be executed together, or may be executed in combination with any technical solution in related technologies.

As shown in FIG. 3, the communication method may include the following steps.

In step 301, a measurement bandwidth and a subband of a carrier are configured, and the network device is communicated with a user equipment (UE) via the subband.

In step 302, a measurement value of the subband fed back by the UE is received.

For the specific implementation process and principles of steps 301 to 302, reference can be made to the description of the above embodiments and will not be described again here.

In step 303, it is determined whether the measurement value of the subband reaches a first threshold corresponding to the subband. If the measurement value of the subband reaches a first threshold corresponding to the subband, step 304 is executed; otherwise, step 305 is executed.

In step 304, subband configuration is adjusted according to the measurement value of the subband.

In step 305, the subband configuration is not adjusted.

The measurement value of the subband may reflect the interference level when the UE communicates with the network device via the subband.

The first threshold may be configured as needed. The first threshold may be configured by the network device, or may be determined according to a protocol, which is not limited in the present disclosure. The first threshold is a threshold for the network device to determine whether to adjust the subband configuration.

It is noted that for different subbands, the same first threshold may be configured, or different first thresholds may also be configured, which is not limited in the present disclosure. In addition, when the types of the measurement value of the subbands are different, the corresponding first thresholds are also different. For example, when the measurement value of the subband is a reference signal received power (RSRP) or a reference signal received quality (RSRQ), the first thresholds corresponding to the subbands are different.

In one embodiment of the present disclosure, after receiving the measurement value of each subband corresponding to each UE fed back by each UE, the network device may determine whether the measurement value of each subband reaches the first threshold corresponding to each subband. When the measurement value of any subband reaches the first threshold corresponding to the subband, the network device may adjust the subband configuration corresponding to the carrier according to the measurement value reaching the first threshold. When the measurement value of each subband does not reach the corresponding first threshold, the network device may determine that the interference between the UEs is small when communicating with the network device, and the subband configuration corresponding to the carrier may not be adjusted at this time.

Taking a certain UE as an example, assuming that the UE corresponds to one subband, when the measurement value fed back by the UE for the corresponding subband reaches the first threshold corresponding to the subband, the network device may determine that the interference is relatively large when the UE communicates with the network device via the subband corresponding to the measurement value. At this time, the network device may adjust the subband configuration corresponding to the carrier according to the measurement value of the subband. For example, the subband type of the subband corresponding to the UE may be adjusted, or the subband type of the subband corresponding to the UE adjacent to the UE is adjusted, etc.

In one embodiment of the present disclosure, when the measurement value of the subband includes one of RSRP, RSRQ, RSSI, or SINR, the network device only needs to determine whether the measurement value of the corresponding subband fed back by each UE reaches the corresponding first threshold, and the subband configuration corresponding to the carrier is adjusted according to the measurement value that reaches the first threshold.

In one embodiment of the present disclosure, when the measurement value of the subband includes two or more of RSRP, RSRQ, RSSI, or SINR, the network device needs to separately determine whether each measurement value fed back by each UE for its subband reaches the corresponding first threshold, and the subband configuration corresponding to the carrier is adjusted according to the measurement value that reaches the first threshold. In an embodiment of the present disclosure, if there are a plurality of measurement values, a corresponding first threshold may be set for each measurement value. Only measurement values exceeding the corresponding first threshold will be reported by the UE. If the measurement value does not exceed the corresponding first threshold, the corresponding measurement value will not be reported. Of course, in other embodiments of the present disclosure, a unified first threshold may also be set, and measurement values exceeding the unified first threshold will be reported. If not, the measurement values will not be reported. In addition, the network device may make a decision based on one of the plurality of measurement values reported by the UE, or make a comprehensive decision based on the plurality of measurement values to adjust the subband configuration.

In one embodiment of the present disclosure, the network device may adjust the subband configuration corresponding to the carrier as follows, such as, adjusting the types of the plurality of the subbands in the carrier, or adjusting the sequence number of the subband corresponding to each UE, or adjusting the types of the plurality of the subbands in the carrier and the sequence numbers of the subbands corresponding to each UE.

Manner 1

The subband types of subband 1 or subband 2 in the carrier are adjusted. For example, the type of subband 1 corresponding to UE-A is adjusted to the downlink type, or the type of subband 2 corresponding to UE-B is adjusted to the uplink type, so as to unify the types of subbands corresponding to UE-A and UE-B.

Manner 2

The sequence numbers of the subbands corresponding to UE-A or UE-B are adjusted. For example, subband 1 is configured to still correspond to UE-A, the uplink type corresponding to subband 1 is maintained to be unchanged, subband 2 is configured to be null, and subband 3 with a subband type of downlink type is configured to correspond to UE-B, so as to isolate the uplink communication between UE-A and the network device and the downlink communication between UE-B and the network device via subband 2.

Manner 3

The subband types of subband 1 or subband 2 in the carrier, and the sequence number of the subband corresponding to UE-A or UE-B are adjusted. For example, subband 1 is configured to still correspond to UE-A, and the type of subband 1 is adjusted to the downlink type, subband 2 is configured as null, and subband 3 with a subband type of downlink type is configured to correspond to UE-B, so as to isolate the downlink communication between UE-A and the network device and the downlink communication between UE-B and the network device via subband 2.

In summary, the network device configures the measurement bandwidth and the subband of the carrier, communicates with the user equipment (UE) via the subband, receives the measurement value of the subband fed back by the UE, and determines whether the measurement value of the subband reaches the first threshold corresponding to the subband. If the measurement value reaches the first threshold corresponding to the subband, the subband configuration is adjusted according to the measurement value of the subband, which realizes that the network device reasonably adjusts the subband configuration corresponding to the carrier according to the measurement value of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

Embodiment of the present disclosure provides another communication method. FIG. 4 is a schematic flowchart of another communication method provided by an embodiment of the present disclosure. The communication method may be applied to a user equipment. The communication method may be executed alone or in combination. Any embodiment or possible implementation in embodiments of the present disclosure may be executed together, or may be executed in combination with any technical solution in the related art.

As shown in FIG. 4, the communication method may include the following steps.

In step 401, a signal sent by subbands in a measurement bandwidth configured by the network device based on the subbands are is received.

The network device may be, for example, abase station. The user equipment (UE) may be a UE covered by the base station. It is noted that the UE in embodiments may be any UE in a cell covered by the network device.

The UE may refer to a device that provides voice and/or data connectivity to users. The UE may communicate with one or more core networks via radio access network (RAN). The UE may be a terminal of an Internet of Things (IoT), such as a sensor device, a mobile phone (or called a cellular phone) and computers with IoT terminal. For example, the user equipment may be fixed, portable, pocket, hand-held, computer built-in or vehicle-mounted devices. For example, the user equipment may be a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the UE may also be equipment of an unmanned aerial vehicle. Alternatively, the UE may also be a vehicle-mounted device, for example, a trip computer with a wireless communication function, or a wireless user equipment connected externally to the trip computer. Alternatively, the UE may also be a roadside device, for example, may be a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

The subband is a continuous frequency band that contains one or more physical resource blocks (PRBs). The physical resource block is a frequency domain unit and consists of continuous subcarriers.

In an illustrative embodiment, the network device may configure the measurement bandwidth of the carrier and divide the measurement bandwidth into a plurality of subbands, and may configure the UE corresponding to each subband and the subband type of each subband, and each UE may communicate with the network device via the corresponding subband. The subband corresponding to the UE refers to the subband configured by the network device and used when communicating with the UE.

The subband configuration is used to configure the types of the plurality of subbands in the carrier. The subband types may include an uplink type, a downlink type and a flexible type.

In one embodiment of the present disclosure, when the types of the subbands corresponding to the UE are different, the ways in which the UE and the network device communicate via the subband are also different.

When the type of the subband is the downlink type, the UE receives data transmitted by the network device on the subband. When the type of the subband is the uplink type, the UE transmits data to the network device on the subband. When the type of the subband is the flexible type, the UE configures the subband for uplink transmission, downlink transmission, or null transmission via a configuration signaling. In one embodiment of the present disclosure, the network device may specifically configure the flexible type of the subband as the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling, so that when the UE determines that the type of the subband corresponding to itself is the flexible type, it may determine whether the subband is used for the uplink transmission, the downlink transmission, or the null transmission via the configuration signaling.

In one embodiment of the present disclosure, when the flexible type of the subband is configured as null, the UE does not perform any operation on the subband.

It is noted that the network device may configure each subband to correspond to one UE, or the network device may also configure a plurality of subbands to correspond to one UE, which is not limited in the present disclosure. In addition, when the same UE corresponds to a plurality of subbands, the types of each subband may be the same or different, which is not limited in the present disclosure.

In step 402, communication quality is measured according to the signal received to generate a measurement value of each subband corresponding to the UE.

In step 403, the measurement value of the subband is sent to the network device.

In an illustrative embodiment, after receiving the signal sent by the subband in the measurement bandwidth configured by the network device based on the subband, the UE may measure the communication quality according to the received signal and generate the measurement value for each subband corresponding to the UE, and then send the measurement value for each subband corresponding to the UE to the network device. That is, the UE may only measure communication quality for each subband of the downlink type corresponding to the UE, generate the measurement value for each subband of the downlink type, and then send the measurement value for the subband of the downlink type to the network device. The measurement value of the subband may reflect the interference level when the UE communicates with the network device via the subband.

It is noted that when the UE corresponds to one subband, the UE may perform communication quality measurement based on the received signal sent by the subband to generate the measurement value of the subband corresponding to the UE, and then send the measurement value of the subband to the network device. When the UE corresponds to a plurality of subbands, the UE may perform communication quality measurements based on the received signals sent by each subband to generate measurement values for each subband corresponding to the UE, and then send the measurement values of each subband to the network device.

Embodiments of the present disclosure provides another communication method. FIG. 5 is a schematic flowchart of another communication method provided by an embodiment of the present disclosure. The communication method may be applied to a user equipment. The communication method may be executed alone or in combination. Any embodiment or possible implementation in embodiments of the present disclosure may be executed together, or may be executed in combination with any technical solution in related art.

As shown in FIG. 5, the communication method may include the following steps.

In step 501, subband configuration sent by a network device via a configuration signaling is received.

In an illustrative embodiment, after the network device configures the measurement bandwidth of the carrier, divides the measurement bandwidth into multiple a plurality of subbands, and configures the UE corresponding to each subband and the subband type of each subband, the network device may send the subband configuration to UE via the configuration signaling, so that the UE may receive the subband configuration sent by the network device via the configuration signaling.

The subband configuration is used to configure the types of the plurality of the subbands in the carrier. The subband types include an uplink type, a downlink type and a flexible type. When the type of the subband is the downlink type, the UE receives data transmitted by the network device on the subband. When the type of the subband is the uplink type, the UE transmits data to the network device on the subband. When the type of the subband is the flexible type, the network device configures the subband as uplink transmission, downlink transmission, or as null transmission via a configuration signaling.

The configuration signaling may be, for example, a radio resource control (RRC) common signaling, a RRC dedicated signaling or a downlink control information (DCI) signaling.

In one embodiment of the present disclosure, the network device may send the subband configuration to a single UE in a cell covered by the network device via the RRC dedicated signaling. The subband configuration sent by the network device to a single UE may be unique to the UE. Correspondingly, the UE in embodiments of the present disclosure may obtain the subband configuration sent by the network device via the RRC dedicated signaling. In another embodiment of the present disclosure, the network device may send the subband configuration to a group of UEs in a cell covered by the network device via the downlink control information (DCI) signaling. The subband configuration sent by the network device to a group of UEs may be shared by the group of UEs. Accordingly, the UE in embodiments of the present disclosure may obtain the subband configuration sent by the network device via the DCI signaling. In another embodiment of the present disclosure, the network device may send subband configurations to all UEs in the cells covered by the network device via the RRC common signaling. The subband configurations sent by the network device to all UEs may be shared by all UEs. Accordingly, the UE in embodiments of the present disclosure may obtain the subband configuration sent by the network device via the RRC common signaling.

In step 502, signals sent by the network device based on the subband in the measurement bandwidth configured by the subband is received.

In step 503, communication quality is measured according to the signal received to generate a measurement value for each subband corresponding to the UE.

In an illustrative embodiment, after the UE receives the subband configuration sent by the network device via a configuration signaling, the UE may determine its corresponding subband and subband type according to the subband configuration, and communicate with the network device based on the corresponding subband. After receiving the signal sent by the subband in the measurement bandwidth configured by the network device based on the subband, the UE may perform communication quality measurement based on the received signal and generate the measurement value of each subband corresponding to the UE. That is, the UE may only perform communication quality measurement for each subband of the downlink type corresponding to the UE, and generate a measurement value for each subband of the downlink type.

The measurement value of the subband includes one or more of RSRP, RSRQ, RSSI, or SINR.

In step 504, an identifier of the measurement bandwidth and an identifier of the subband are sent to the network device.

In an illustrative embodiment, after the UE generates the measurement value of the subband, the UE may send the measurement value of the subband to the network device. In addition, in order to enable the network device to distinguish which subband measurement value the subband measurement value sent by the UE is and which subband in the measurement bandwidth the subband is, the UE may send the identifier of the subband corresponding to the measurement value of the subband and the identifier of the corresponding measurement bandwidth to the network device while sending the measurement value of the subband.

In an illustrative embodiment, when the UE sends the identifier of the measurement bandwidth, the identifier of the subband, and the measurement value of the subband to the network device, the transmission may be performed in various forms.

In one embodiment of the present disclosure, the UE may send the identifier of the measurement bandwidth, the identifier of the subband, and the measurement value of the subband to the network device in a form of a list. The position in the list one-to-one corresponds to the identifier of the subband and the identifier of the measurement bandwidth. The UE may place the measurement value of each subband in the corresponding position of the list, so that the measurement value of each subband one-to-one corresponds to the identifier of the subband and the identifier of the measurement bandwidth.

In another embodiment of the present disclosure, the UE may send the identifier of the measurement bandwidth, the identifier of the subband, and the measurement value of the subband to the network device in the form of one or more “identifier+measurement value of the subband” in series.

In an illustrative embodiment, after the UE sends the identifier of the measurement bandwidth, the identifier of the subband, and the measurement value of the subband to the network device, the network device may adjust the subband configuration corresponding to the carrier according to the measurement value of the subband, and send the adjusted subband configuration to the UE. Correspondingly, the UE may also receive the adjusted subband configuration to communicate with the network device through the adjusted subband configuration.

In summary, the UE receives the subband configuration sent by the network device via the configuration signaling, receives the signal sent by the subband in the measurement bandwidth of the network device based on the subband configuration, performs communication quality measurement based on the received signal to generate the measurement value of each subband corresponding the UE, sends the identifier of the measurement bandwidth, the identifier of the subband, and the measurement value of the subband to the network device, which may assist the network device to reasonably adjust the subband configuration corresponding to the carrier according to the measurement value of the subband fed back by the UE, thereby avoiding the problem of mutual interference between a plurality of UEs.

Embodiments of the present disclosure provide a communication method. FIG. 6 is a schematic flowchart of a communication method provided by an embodiment of the present disclosure. The communication method may be applied to a user equipment. The communication method may be executed alone or in combination with any embodiment or possible implementation in embodiments, and also be combined with any technical solution in related art.

As shown in FIG. 6, the communication method may include the following steps.

In step 601, signals sent by a network device based on a subband in a measurement bandwidth configured by the subband is received.

In step 602, communication quality is measured according to the signal received to generate a measurement value of each subband corresponding to the UE.

The measurement value of the subband may include one or more of RSRP, RSRQ, RSSI, or SINR.

It is noted that when the UE corresponds to one subband, the UE may perform communication quality measurement based on the received signal sent by the subband to generate the measurement value of the subband corresponding to the UE. When the UE corresponds to a plurality of subbands, the UE may measure communication quality based on the received signal sent by each subband to generate a measurement value of each subband corresponding to the UE.

In step 603, it is determined whether the measurement value of the subband is greater than or equal to a second threshold corresponding to the subband. If the measurement value of the subband is greater than or equal to the second threshold, step 604 is performed; otherwise, step 605 is performed.

In step 604, a measurement value of the subband is sent to the network device.

In step 605, the measurement value of the subband is not sent to the network device.

The measurement value of the subband may reflect the interference level when the UE communicates with the network device via the subband.

The second threshold may be configured as needed. The second threshold may be configured by the network device or may be determined according to a protocol, which is not limited in the present disclosure. The second threshold is a threshold for the UE side to determine whether to report the measurement values.

It is noted that for different subbands, the same second threshold may be configured, or different second thresholds may also be configured, which is not limited in the present disclosure. In addition, when the types of measurement values of the subbands are different, the corresponding second thresholds are also different. For example, when the measurement value of the subband is a reference signal received power (RSRP) or a reference signal received quality (RSRQ), the second thresholds corresponding to the subbands are different.

In an embodiment of the present disclosure, when the UE corresponds to one subband, the UE may determine whether the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband. If the measurement value of the subband is greater than or equal to the second threshold, it indicates that the interference between the UE and the network device is relatively large when the UE communicates with the network device via the subband corresponding to the measurement value, and the measurement value of the subband may be sent to the network device. If the measurement value of the subband is less than the second threshold corresponding to the subband, it indicates that the interference between the UE and the network device is small when the UE communicates with the network device via the subband corresponding to the measurement value, and the measurement value of the subband does not need to be sent to the network device.

In another embodiment of the present disclosure, when the UE corresponds to a plurality of subbands, for each subband, the UE may determine whether the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband. If the measurement value of any subband is greater than or equal to the second threshold corresponding to the subband, it indicates that the interference between the UE and the network device is relatively large when the UE communicates with the network device via the subband corresponding to the measurement, and the measurement value greater than or equal to the second threshold may be sent to the network device. If the measurement values of each subband are less than the corresponding second threshold, it means that the interference between the UE and the network device is small when the UE communicates with the network device via the subbands corresponding to each measurement value, and the measurement value of subbands do not need to be sent to the network device.

In an embodiment of the present disclosure, when the measurement value of the subband includes one of RSRP, RSRQ, RSSI or SINR, the UE only needs to determine whether the measurement value of one or more subbands is greater than or equal to the second threshold, and send the measurement value of subbands greater than or equal to the second threshold to the network device.

In one embodiment of the present disclosure, when the measurement value of the subband includes two or more of RSRP, RSRQ, RSSI, or SINR, the UE needs to separately determine whether each measurement value of one or more subbands is greater than or equal to the second threshold, and send the measurement value of the subbands greater than or equal to the second threshold to the network device. In one embodiment of the present disclosure, if there are a plurality of measurement values, the corresponding second threshold may be set for each measurement value, and only measurement values exceeding the corresponding second threshold will be reported by the UE to the network device. If the measurement value does not exceed the corresponding second threshold, the corresponding measurement value will not be reported by the UE. Of course, in other embodiments of the present disclosure, a unified second threshold may also be set, and the measurement values exceeding the unified second threshold will be reported. If the measurement values do not exceed the unified second threshold, they will not be reported. In addition, for the plurality of the measurement values reported by the UE, the network device may make a decision based on one of the plurality of the measurement values, or make a comprehensive decision based on the plurality of measurement values to adjust the subband configuration.

In summary, the UE receives the signal sent by the subband in the measurement bandwidth configured by the network device based on the subband, performs communication quality measurement according to the received signal to generate the measurement value of each subband corresponding to the UE, and determines whether the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband. If the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband, the measurement value of the subband is sent to the network device. Otherwise, the measurement value of the subband is not sent to the network device, which may assist the network device to reasonably adjust the subband configuration corresponding to the carrier according to the measurement values of the subband fed back by the UE, thus avoiding the problem of mutual interference between the plurality of UEs.
