Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] In related technologies, with the development of radio frequency interference cancellation technology and digital domain interference cancellation technology, in some scenarios, the same frequency and full-duplex technology can be used on the network equipment side. However, due to the limitations of user equipment size, cost and other factors, time division duplex (TDD) or frequency division duplex (FDD) technology needs to be used on the user equipment side.

[0003] In this scenario, because network devices may use the same time and frequency to send and receive data, mutual interference may occur between multiple user devices in the same cell or adjacent cells. How to avoid mutual interference between multiple user devices is a problem that needs to be solved. Summary of the Invention

These terms are only used to distinguish information of the same type from one another.

[0064] Embodiments of this disclosure are described in detail below, with examples of embodiments illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0065] Figure 1 This disclosure provides a communication method according to an embodiment. It should be noted that the communication method of this disclosure is applied to a network device.

[0066] like Figure 1 As shown, the communication method may include the following steps:

[0067] Step 101: Configure the carrier's measurement bandwidth and subband, and communicate with the user equipment (UE) through the subband.

[0068] Among them, network equipment can be, for example, a base station; user equipment (UE) can be a UE covered by the base station.

[0069] The UE can be a device that provides voice and / or data connectivity to a user. The UE can communicate with one or more core networks via a Radio Access Network (RAN). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with an IoT terminal, for example, a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can be a device in an unmanned aerial vehicle (UAV). Alternatively, the UE can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0070] It should be noted that, in the embodiments of this disclosure, the UE communicating with the network device can 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. This disclosure does not impose any limitations on this. The embodiments of this disclosure are illustrated using all UEs as an example.

[0071] A subband is a continuous frequency band that contains one or more physical resource blocks (PRBs); a physical resource block is a frequency domain unit composed of consecutive subcarriers.

[0072] In an exemplary embodiment, the network device can configure the measurement bandwidth of the carrier and divide the measurement bandwidth into multiple subbands. It can also configure the UE corresponding to each subband and the subband type for each subband, thereby communicating with each UE through the subband corresponding to each UE. Here, the subband corresponding to the UE refers to the subband configured by the network device for communication with that UE.

[0073] The subband type can include uplink type, downlink type, and flexible type.

[0074] In one embodiment of this disclosure, when the type of subband corresponding to the UE is different, the way the network device communicates with the UE through the subband is also different.

[0075] Specifically, when the subband type is downlink, the network device can send data to the UE on the subband; when the subband type is uplink, the network device can receive data sent by the UE on the subband; when the subband type is flexible, the network device can perform uplink transmission, downlink transmission, or leave it idle on the subband. In one embodiment of this disclosure, the network device can configure a flexible subband as uplink transmission, downlink transmission, or leave it idle through configuration signaling. Thus, when the UE determines that the subband corresponding to it is of flexible type, it can determine through configuration signaling whether the subband is used for uplink transmission, downlink transmission, or is left idle.

[0076] In one embodiment of this disclosure, when a flexible type subband is configured as idle, the network device does not perform any operation on that subband.

[0077] It should be noted that the network device can be configured to correspond to one UE for each sub-band, or multiple sub-bands can be configured to correspond to one UE; this disclosure does not impose any restrictions on this. Furthermore, when the same UE corresponds to multiple sub-bands, the types of the sub-bands may be the same or different; this disclosure does not impose any restrictions on this.

[0078] Step 102: Receive the measurement values ​​for the subband fed back by the UE.

[0079] In an exemplary embodiment, each UE can perform communication quality measurements for communication with the network device via a corresponding subband, generate measurement values ​​for the subband, and then feed back the subband measurement values ​​to the network device. The subband measurement values ​​can reflect the level of interference when the UE communicates with the network device via that subband.

[0080] It should be noted that for the same UE, when the UE corresponds to one sub-band, the UE feeds back the measurement value for that one sub-band to the network device. When the UE corresponds to multiple sub-bands, the UE feeds back the measurement value for each sub-band to the network device.

[0081] In one embodiment of this disclosure, each UE can perform communication quality measurements only for the subband of the downlink type corresponding to that UE, generate measurement values ​​for the subband of that downlink type, and then feed back the measurement values ​​for the subband of the downlink type to the network device.

[0082] Step 103: Adjust the subband configuration corresponding to the carrier based on the subband measurement values.

[0083] In an exemplary embodiment, after receiving measurement values ​​for the corresponding sub-bands from each UE, the network device can adjust the sub-band configuration corresponding to the carrier based on the measurement values. Specifically, the network device can adjust the types of multiple sub-bands within the carrier and the UEs corresponding to each sub-band.

[0084] For example, suppose the network device configures user equipment A (UE-A) with subband 1 of type uplink and user equipment B (UE-B) with subband 2 of type downlink, and UE-A and UE-B are close to each other. Suppose that after the network device communicates with UE-A and UE-B through their respective subbands, UE-B feeds back the network device a measurement value for its corresponding downlink subband 2, indicating that the communication between UE-B and the network device is interfered with by UE-A. Then, the network device can adjust the subband configuration of the carrier as follows: unify the subband types corresponding to UE-A and UE-B, for example, changing the type of subband 1 corresponding to UE-A to downlink, or changing the type of subband 2 corresponding to UE-B to uplink; or the network device can add an empty subband between the subbands corresponding to UE-A and UE-B to isolate the communication between UE-A and the network device, as well as the communication between UE-B and the network device.

[0085] This allows the network device to reasonably adjust the subband configuration corresponding to the carrier based on the subband measurement values ​​fed back by the UE when there is mutual interference between uplink and downlink services between UEs, so as to avoid mutual interference between UEs when communicating with the network device.

[0086] In summary, by configuring the measurement bandwidth and subband of the carrier through network equipment, communicating with the user equipment (UE) through the subband, receiving the measurement values ​​of the subband fed back by the UE, and adjusting the subband configuration corresponding to the carrier based on the measurement values ​​of the subband, the network equipment can reasonably adjust the subband configuration corresponding to the carrier based on the measurement values ​​of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

[0087] This disclosure provides another communication method. Figure 2 This is a flowchart illustrating another communication method provided in an embodiment of the present disclosure. This communication method can be applied to network devices. The communication method can be executed alone, or it can be executed together with any embodiment of the present disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0088] like Figure 2 As shown, the communication method may include the following steps:

[0089] Step 201: Configure the carrier's measurement bandwidth and subband, send the subband configuration to the UE through configuration signaling, and communicate with the user equipment UE through the subband.

[0090] In an exemplary embodiment, the network device can configure the measurement bandwidth of the carrier and divide the measurement bandwidth into multiple subbands. It can also configure the UE corresponding to each subband and the subband type of each subband, and send the subband configuration to the UE through configuration signaling, thereby communicating with each UE through the subband corresponding to each UE after configuration.

[0091] The subband configuration is used to configure the types of multiple subbands in a carrier. The subband types include uplink, downlink, and flexible types. When the subband type is downlink, the network device can send data to the UE on the subband; when the subband type is uplink, the network device can receive data sent by the UE on the subband; when the subband type is flexible, the network device can perform uplink transmission, downlink transmission, or leave it idle on that subband. In one embodiment of this disclosure, the network device can configure a flexible type subband specifically as uplink transmission, downlink transmission, or leave it idle through configuration signaling. Therefore, when the UE determines that the subband corresponding to it is of the flexible type, it can determine through configuration signaling whether the subband is used for uplink transmission, downlink transmission, or is left idle.

[0092] In an exemplary embodiment, a network device can send subband configuration to a single UE, a group of UEs, or all UEs covered by the network device via configuration signaling. The configuration signaling can be, for example, Radio Resource Control (RRC) public signaling, RRC-specific signaling, or Downlink Control Information (DCI) signaling.

[0093] In one embodiment of this disclosure, a network device can send subband configuration to a single UE within a cell covered by the network device via RRC dedicated signaling. The subband configuration sent by the network device to a single UE may be UE-specific. In another embodiment of this disclosure, a network device can send subband configuration to a group of UEs within a cell covered by the network device via Downlink Control Information (DCI) signaling. The subband configuration sent by the network device to the group of UEs may be shared by the group of UEs. In yet another embodiment of this disclosure, a network device can send subband configuration to all UEs within a cell covered by the network device via RRC common signaling. The subband configuration sent by the network device to all UEs may be shared by all UEs.

[0094] Step 202: Receive the measurement values ​​for the subband fed back by the UE.

[0095] In an exemplary embodiment, the subband measurements may include one or more of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), and Signal-to-Noise and Interference Ratio (SINR).

[0096] For a detailed description of step 202, please refer to the relevant descriptions in the above embodiments. This disclosure will not repeat the details here.

[0097] Step 203: Adjust the subband configuration corresponding to the carrier based on the subband measurement values.

[0098] In an exemplary embodiment, after receiving measurement values ​​for the corresponding sub-bands from each UE, the network device can adjust the sub-band configuration corresponding to the carrier based on the measurement values. Specifically, the network device can adjust the types of multiple sub-bands within the carrier and the sequence number of the sub-band corresponding to each UE, etc.

[0099] For example, suppose the network device configures UE-A's subband 1 as uplink type and UE-B's subband 2 as downlink type, and UE-A and UE-B are close to each other. Suppose that after the network device communicates with UE-A and UE-B through their respective subbands, UE-B feeds back the network device a measurement value for its corresponding downlink type subband 2. This measurement value for subband 2 indicates mutual interference between UE-A and UE-B during communication with the network device. The network device could then adjust the subband configuration as follows: unify the subband types for UE-A and UE-B, for example, changing the type of subband 1 for UE-A to downlink type, or changing the type of subband 2 for UE-B to uplink type; or the network device could maintain the uplink type of subband 1, configure subband 2 as unused, and configure subband 3 for UE-B, thus isolating communication between UE-A and the network device, as well as communication between UE-B and the network device.

[0100] This allows the network device to reasonably adjust the subband configuration corresponding to the carrier based on the subband measurement values ​​fed back by the UE when there is mutual interference between uplink and downlink services between UEs, so as to avoid mutual interference between UEs when communicating with the network device.

[0101] Step 204: Send the adjusted subband configuration to the UE.

[0102] In an exemplary embodiment, after adjusting the subband configuration corresponding to the carrier based on the subband measurement values, the network device can also send the adjusted subband configuration to each UE, so that each UE can determine its corresponding subband and subband type after the subband configuration is adjusted, thereby enabling the network device and each UE to communicate with each UE through the subband with the adjusted subband configuration. Specifically, the network device can send the adjusted subband configuration to the UE through configuration signaling. The specific process of sending the adjusted subband configuration to the UE can refer to the process of sending subband configuration to the UE described above, and will not be repeated here.

[0103] In summary, by configuring the carrier's measurement bandwidth and subbands through network equipment, sending subband configuration to the UE via configuration signaling, and communicating with the UE through the subband, the network equipment receives measurement values ​​for the subband from the UE, adjusts the subband configuration corresponding to the carrier based on these measurement values, and sends the adjusted subband configuration back to the UE. This enables the network equipment to reasonably adjust the subband configuration corresponding to the carrier based on the measurement values ​​for the subband from the UE, thereby avoiding mutual interference between multiple UEs.

[0104] This disclosure provides another communication method. Figure 3 This is a flowchart illustrating another communication method provided in an embodiment of the present disclosure. This communication method can be applied to network devices. The communication method can be executed alone, or it can be executed together with any embodiment of the present disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0105] like Figure 3 As shown, the communication method may include the following steps:

[0106] Step 301: Configure the carrier's measurement bandwidth and subband, and communicate with the user equipment (UE) through the subband.

[0107] Step 302: Receive the measurement values ​​for the sub-band fed back by the UE.

[0108] The specific implementation process and principle of steps 301-302 can be referred to the description of the above embodiments, and will not be repeated here.

[0109] Step 303: Determine whether the measured value of the sub-band reaches the first threshold corresponding to the sub-band. If yes, proceed to step 304; otherwise, proceed to step 305.

[0110] Step 304: Adjust the sub-band configuration based on the sub-band measurement values.

[0111] Step 305: Do not adjust the sub-band configuration.

[0112] The sub-band measurement can reflect the level of interference when the UE communicates with network devices through that sub-band.

[0113] The first threshold can be configured as needed. This first threshold can be configured by the network device or determined according to protocol specifications; this disclosure does not impose any restrictions on it. This first threshold is the threshold used by the network device to determine whether to adjust the subband configuration.

[0114] It should be noted that the same first threshold can be configured for different sub-bands, or different first thresholds can be configured; this disclosure does not impose any limitation on this. Furthermore, the corresponding first threshold will also differ depending on the type of measurement value of the sub-band. For example, when the measurement value of the sub-band is the reference signal received power (RSRP) or the reference signal received quality (RSRQ), the corresponding first threshold for the sub-band will be different.

[0115] In one embodiment of this disclosure, after receiving the measurement values ​​for each sub-band corresponding to each UE from each UE, the network device can determine whether the measurement value of each sub-band reaches the first threshold corresponding to each sub-band. When the measurement value of any sub-band reaches the first threshold corresponding to that sub-band, the network device can adjust the sub-band configuration corresponding to the carrier based on the measurement value that reaches the first threshold. When the measurement values ​​of each sub-band do not reach the corresponding first threshold, the network device can determine that the interference between each UE is small when communicating with the network device, and at this time, the sub-band configuration corresponding to the carrier does not need to be adjusted.

[0116] Taking a UE as an example, assuming that the UE corresponds to a subband, when the measurement value of the UE for its corresponding subband reaches the first threshold of the subband, the network device can determine that the UE is experiencing significant interference when communicating with the network device through the subband corresponding to the measurement value. At this time, the network device can adjust the subband configuration corresponding to the carrier based on the measurement value of the subband. For example, it can adjust the subband type of the subband corresponding to the UE, or adjust the subband type of the subband corresponding to the UE adjacent to the UE, etc.

[0117] In one embodiment of this disclosure, when the measurement value of the subband includes one of RSRP, RSRQ, RSSI, and SINR, the network device only needs to determine whether the measurement value fed back by each UE for its corresponding subband reaches the corresponding first threshold, and adjust the subband configuration corresponding to the carrier according to the measurement value that reaches the first threshold.

[0118] In one embodiment of this disclosure, when the subband measurement values ​​include two or more of RSRP, RSRQ, RSSI, and SINR, the network device needs to determine whether each measurement value reported by each UE for its subband reaches the corresponding first threshold, and adjust the subband configuration corresponding to the carrier based on the measurement values ​​that reach the first threshold. In one embodiment of this disclosure, if there are multiple measurement values, a corresponding first threshold can be set for each measurement value. Only measurement values ​​exceeding the corresponding first threshold will be reported by the UE; if they do not exceed the corresponding first threshold, the corresponding measurement value will not be reported. Of course, in other embodiments of this disclosure, a unified first threshold can also be set. Measurement values ​​exceeding the unified first threshold will be reported, and those not exceeding it will not be reported. Furthermore, for multiple measurement values ​​reported by the UE, the network device can make a decision based on one of the multiple measurement values, or it can make a comprehensive decision based on multiple measurement values, thereby adjusting the subband configuration.

[0119] In one embodiment of this disclosure, the network device may, for example, adjust the subband configuration corresponding to the carrier as follows: adjust the type of multiple subbands in the carrier, or adjust the sequence number of the subband corresponding to each UE, or adjust the type of multiple subbands in the carrier and the sequence number of the subband corresponding to each UE, etc.

[0120] For example, suppose the network device configures UE-A to use uplink subband 1 and UE-B to use downlink subband 2, and UE-A and UE-B are relatively close. After the network device communicates with UE-A and UE-B through their respective subbands, UE-B sends back a measurement value for its downlink subband 2, indicating mutual interference between UE-A and UE-B during communication with the network device. In this case, the network device can adjust the subband configuration of the carrier as follows:

[0121] Method 1

[0122] Adjust the subband type of subband 1 or subband 2 in the carrier, for example, adjust the type of subband 1 corresponding to UE-A to downlink type, or adjust the type of subband 2 corresponding to UE-B to uplink type, so as to unify the subband types corresponding to UE-A and UE-B respectively;

[0123] Method 2

[0124] Adjust the sequence number of the subband corresponding to UE-A or UE-B. For example, configure subband 1 to still correspond to UE-A and keep the uplink type of subband 1 unchanged. Configure subband 2 to be empty and configure subband 3, which is of the downlink type, 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 through subband 2.

[0125] Method 3

[0126] The subband type of subband 1 or subband 2 in the carrier, and the subband number corresponding to UE-A or UE-B are adjusted. For example, subband 1 is still configured to correspond to UE-A, the type of subband 1 is adjusted to downlink type, subband 2 is configured to be empty, and subband 3, which is 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 through subband 2.

[0127] In summary, by configuring the carrier's measurement bandwidth and subbands through network devices, communicating with the User Equipment (UE) via the subbands, receiving measurement values ​​for the subbands from the UEs, and determining whether the subband measurement values ​​have reached the corresponding first threshold, the subband configuration is adjusted based on the measurement values. This allows the network devices to reasonably adjust the subband configuration corresponding to the carrier based on the measurement values ​​for the subbands fed back by the UEs, thereby avoiding the problem of mutual interference between multiple UEs.

[0128] This disclosure provides another communication method. Figure 4 This is a flowchart illustrating another communication method provided in an embodiment of the present disclosure. This communication method can be applied to a user equipment. The communication method can be executed alone, or it can be executed together with any embodiment of the present disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0129] like Figure 4 As shown, the communication method may include the following steps:

[0130] Step 401: Receive signals transmitted by the network device from the subband within the measured bandwidth based on the subband configuration.

[0131] In this context, the network device can be, for example, a base station; the user equipment (UE) can be a UE covered by the base station. It should be noted that, in this embodiment, the UE can be any UE within the cell covered by the network device.

[0132] The UE can be a device that provides voice and / or data connectivity to a user. The UE can communicate with one or more core networks via a Radio Access Network (RAN). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with an IoT terminal, for example, a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can be a device in an unmanned aerial vehicle (UAV). Alternatively, the UE can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0133] A subband is a continuous frequency band that contains one or more physical resource blocks (PRBs); a physical resource block is a frequency domain unit composed of consecutive subcarriers.

[0134] In an exemplary embodiment, the network device can configure the measurement bandwidth of the carrier and divide the measurement bandwidth into multiple subbands. It can also configure the UE corresponding to each subband and the subband type for each subband, so that each UE can communicate with the network device through its corresponding subband. Here, the subband corresponding to the UE refers to the subband configured by the network device for communication with that UE.

[0135] The subband configuration is used to configure the types of multiple subbands within a carrier. The subband types can include uplink type, downlink type, and flexible type.

[0136] In one embodiment of this disclosure, when the type of the subband corresponding to the UE is different, the way the UE communicates with the network device through the subband is also different.

[0137] Specifically, when the subband type is downlink, the UE can receive data sent by the network device on the subband; when the subband type is uplink, the UE can send data to the network device on the subband; when the subband type is flexible, the UE can determine, through configuration signaling, whether the subband is for uplink transmission, downlink transmission, or is idle. In one embodiment of this disclosure, the network device can configure a flexible subband as uplink transmission, downlink transmission, or idle through configuration signaling. Thus, when the UE determines that the subband corresponding to it is of flexible type, it can determine through configuration signaling whether the subband is for uplink transmission, downlink transmission, or is idle.

[0138] In one embodiment of this disclosure, when a flexible type subband is configured as idle, the UE does not perform any operation on that subband.

[0139] It should be noted that the network device can be configured to correspond to one UE for each sub-band, or multiple sub-bands can be configured to correspond to one UE; this disclosure does not impose any restrictions on this. Furthermore, when the same UE corresponds to multiple sub-bands, the types of the sub-bands may be the same or different; this disclosure does not impose any restrictions on this.

[0140] Step 402: Perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE.

[0141] Step 403: Send the sub-band measurement values ​​to the network device.

[0142] In an exemplary embodiment, after receiving a signal transmitted by the network device within a subband of the measurement bandwidth configured by the subband, the UE can perform communication quality measurements based on the received signal, generate measurement values ​​for each subband corresponding to the UE, and then send the measurement values ​​for each subband corresponding to the UE to the network device. That is, the UE can perform communication quality measurements only for each subband of its downlink type, generate measurement values ​​for each subband of that downlink type, and then send the measurement values ​​for that subband of that downlink type to the network device. The subband measurement values ​​can reflect the level of interference when the UE and the network device communicate through that subband.

[0143] It should be noted that when a UE corresponds to one sub-band, the UE can perform communication quality measurements based on the signals received from that sub-band to generate the measurement value for that sub-band, and then send the measurement value of that sub-band to the network device; when a UE corresponds to multiple sub-bands, the UE can perform communication quality measurements based on the signals received from each sub-band to generate the measurement value for each sub-band, and then send the measurement value of each sub-band to the network device.

[0144] In summary, by having the UE receive signals transmitted by the network device within the subband of the measurement bandwidth based on the subband configuration, and then perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE, and sending the subband measurement values ​​to the network device, the network device can be assisted in making reasonable adjustments to the subband configuration corresponding to the carrier based on the measurement values ​​of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

[0145] This disclosure provides another communication method. Figure 5 This is a flowchart illustrating another communication method provided in an embodiment of the present disclosure. This communication method can be applied to a user equipment. The communication method can be executed alone, or it can be executed together with any embodiment of the present disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0146] like Figure 5 As shown, the communication method may include the following steps:

[0147] Step 501: Receive the subband configuration sent by the network device through configuration signaling.

[0148] In an exemplary embodiment, after the network device configures the measurement bandwidth of the carrier, divides the measurement bandwidth into multiple subbands, and configures the UE corresponding to each subband and the subband type of each subband, it can send the subband configuration to the UE through configuration signaling, so that the UE can receive the subband configuration sent by the network device through configuration signaling.

[0149] The subband configuration is used to configure the types of multiple subbands in a carrier. The subband types include uplink, downlink, and flexible types. Specifically, when the subband type is downlink, the UE receives data transmitted by the network device on the subband; when the subband type is uplink, the UE transmits data to the network device on the subband; and when the subband type is flexible, the network device configures the subband for uplink transmission, downlink transmission, or leaves it idle via configuration signaling.

[0150] The configuration signaling can be, for example, Radio Resource Control (RRC) common signaling, RRC dedicated signaling, or Downlink Control Information (DCI) signaling.

[0151] In one embodiment of this disclosure, a network device can send subband configuration to a single UE within a cell covered by the network device via RRC dedicated signaling. The subband configuration sent by the network device to a single UE may be unique to that UE. Accordingly, the UE in this embodiment can obtain the subband configuration sent by the network device via RRC dedicated signaling. In another embodiment of this disclosure, a network device can send subband configuration to a group of UEs within a cell covered by the network device via Downlink Control Information (DCI) signaling. The subband configuration sent by the network device to the group of UEs may be shared by the group of UEs. Accordingly, the UE in this embodiment can obtain the subband configuration sent by the network device via DCI signaling. In yet another embodiment of this disclosure, a network device can send subband configuration to all UEs within a cell covered by the network device via RRC common signaling. The subband configuration sent by the network device to all UEs may be shared by all UEs. Accordingly, the UE in this embodiment can obtain the subband configuration sent by the network device via RRC common signaling.

[0152] Step 502: Receive signals transmitted by the network device from the subband within the measured bandwidth based on the subband configuration.

[0153] Step 503: Perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE.

[0154] In an exemplary embodiment, after receiving the subband configuration sent by the network device via configuration signaling, the UE can determine its corresponding subband and subband type based on the subband configuration, and communicate with the network device using the corresponding subband. After receiving a signal sent by the network device from a subband within the measurement bandwidth of the subband configuration, the UE can perform communication quality measurements based on the received signal and generate measurement values ​​for each subband corresponding to the UE. That is, the UE can perform communication quality measurements only for each subband of its corresponding downlink type and generate measurement values ​​for each subband of that downlink type.

[0155] The subband measurements may include one or more of RSRP, RSRQ, RSSI, and SINR.

[0156] Step 504: Send the identifier of the measured bandwidth, the identifier of the sub-band, and the measured value of the sub-band to the network device.

[0157] In an exemplary embodiment, after generating the measurement value of the subband, the UE can send the measurement value of the subband to the network device. Furthermore, in order for the network device to distinguish which subband the measurement value sent by the UE belongs to, and within which measurement bandwidth the subband belongs, the UE can simultaneously send the identifier of the subband corresponding to the measurement value and the identifier of the corresponding measurement bandwidth to the network device when sending the measurement value of the subband.

[0158] In an exemplary embodiment, when the UE sends the identifier of the measured bandwidth, the identifier of the sub-band, and the measured value of the sub-band to the network device, it can send them in various forms.

[0159] In one embodiment of this disclosure, the UE can send the identifier of the measurement bandwidth, the identifier of the sub-band, and the measurement value of the sub-band to the network device in the form of a list. The positions in the list correspond one-to-one with the identifiers of the sub-band and the measurement bandwidth. The UE can place the measurement value of each sub-band in the corresponding position in the list, so that each measurement value of a sub-band corresponds one-to-one with the identifier of the sub-band and the identifier of the measurement bandwidth.

[0160] In another embodiment of this disclosure, the UE may send the identifier of the measured bandwidth, the identifier of the sub-band, and the measured value of the sub-band to the network device in the form of one or more "identifiers + sub-band measurement values" concatenated.

[0161] In an exemplary embodiment, after the UE sends the identifier of the measured bandwidth, the identifier of the subband, and the measured value of the subband to the network device, the network device can adjust the subband configuration corresponding to the carrier according to the measured value of the subband, and can send the adjusted subband configuration to the UE. Correspondingly, the UE can also receive the adjusted subband configuration to communicate with the network device through the subband with the adjusted subband configuration.

[0162] In summary, by having the UE receive the subband configuration sent by the network device through configuration signaling, and receive the signals sent by the network device in the subband within the measurement bandwidth of the subband configuration, and perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE, and sending 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 can be assisted in making reasonable adjustments to the subband configuration corresponding to the carrier based on the measurement values ​​of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

[0163] This disclosure provides a communication method. Figure 6This is a flowchart illustrating a communication method provided in an embodiment of this disclosure. This communication method can be applied to user equipment. It can be executed alone, or in conjunction with any embodiment of this disclosure or possible implementations thereof, or in conjunction with any technical solution in related technologies.

[0164] like Figure 6 As shown, the communication method may include the following steps:

[0165] Step 601: Receive signals transmitted by the network device from the subband within the measured bandwidth based on the subband configuration.

[0166] Step 602: Perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE.

[0167] The subband measurements may include one or more of RSRP, RSRQ, RSSI, and SINR.

[0168] It should be noted that when a UE corresponds to one sub-band, the UE can perform communication quality measurements based on the signals received from that sub-band to generate the measurement value for that sub-band; when a UE corresponds to multiple sub-bands, the UE can perform communication quality measurements based on the signals received from each sub-band to generate the measurement value for each sub-band.

[0169] Step 603: Determine whether the measured value of the sub-band is greater than or equal to the second threshold corresponding to the sub-band. If yes, proceed to step 604; otherwise, proceed to step 605.

[0170] Step 604: Send the sub-band measurement values ​​to the network device.

[0171] Step 605: Do not send the subband measurements to the network device.

[0172] The sub-band measurement can reflect the level of interference when the UE communicates with network devices through that sub-band.

[0173] The second threshold can be configured as needed. This second threshold can be configured by the network device or determined according to protocol specifications; this disclosure does not impose any restrictions on it. This second threshold is the threshold used by the UE to determine whether to report measurement values.

[0174] It should be noted that the same second threshold can be configured for different subbands, or different second thresholds can be configured; this disclosure does not impose any limitations on this. Furthermore, the corresponding second threshold will differ depending on the type of measurement value of the subband. For example, when the measurement value of the subband is the reference signal received power (RSRP) or the reference signal received quality (RSRQ), the corresponding second threshold for the subband will be different.

[0175] In one embodiment of this disclosure, when a UE corresponds to a subband, the UE can determine whether the measured value of the subband is greater than or equal to the second threshold corresponding to the subband. If the measured value of the subband is greater than or equal to the second threshold corresponding to the subband, it indicates that there is significant interference when the UE communicates with the network device through the subband corresponding to the measured value, and the measured value of the subband can be sent to the network device. If the measured value of the subband is less than the second threshold corresponding to the subband, it indicates that there is less interference when the UE communicates with the network device through the subband corresponding to the measured value, and the measured value of the subband can be left unsent to the network device.

[0176] In another embodiment of this disclosure, when the UE corresponds to multiple subbands, for each subband, the UE can determine whether the measured value of the subband is greater than or equal to the second threshold corresponding to the subband. If the measured value of any subband is greater than or equal to the second threshold corresponding to that subband, it indicates that the interference between the UE and the network device is large when communicating through the subband corresponding to the measured value greater than or equal to the second threshold. In this case, the measured value of the subband greater than or equal to the second threshold can be sent to the network device. If the measured value of each subband is less than the corresponding second threshold, it indicates that the interference between the UE and the network device is small when communicating through the subband corresponding to each measured value. In this case, the measured value of the subband can be left unsent to the network device.

[0177] In one embodiment of this disclosure, when the measurement value of a subband includes one of RSRP, RSRQ, RSSI, and SINR, the UE only needs to determine whether the measurement value of one or more subbands is greater than or equal to a second threshold, and send the measurement value of the subband that is greater than or equal to the second threshold to the network device.

[0178] In one embodiment of this disclosure, when the measurement values ​​of a subband include two or more of RSRP, RSRQ, RSSI, and SINR, the UE needs to determine whether each measurement value of one or more subbands is greater than or equal to a second threshold, and send the measurement values ​​of the subbands that are greater than or equal to the second threshold to the network device. In another embodiment of this disclosure, if there are multiple measurement values, a corresponding second threshold can be set for each measurement value. Only measurement values ​​exceeding the corresponding second threshold will be reported by the UE to the network device; if they do not exceed the corresponding second threshold, the corresponding measurement value will not be reported by the UE. Of course, in other embodiments of this disclosure, a unified second threshold can also be set. Measurement values ​​exceeding this unified second threshold will be reported, and those not exceeding it will not be reported. Furthermore, the network device can make a decision based on one of the multiple measurement values ​​reported by the UE, or it can make a comprehensive decision based on multiple measurement values, thereby adjusting the subband configuration.

[0179] In summary, by having the UE receive signals transmitted by the network device within the subband of the measurement bandwidth configured by the subband, and perform communication quality measurements based on the received signals to generate measurement values ​​for each subband corresponding to the UE, the system determines whether the measurement value of the subband is greater than or equal to the second threshold corresponding to the subband. If so, the measurement value of the subband is sent to the network device; otherwise, it is not sent. This helps the network device to reasonably adjust the subband configuration corresponding to the carrier based on the measurement values ​​of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

[0180] With the above Figures 1 to 3 Corresponding to the communication method provided in the embodiments, this disclosure also provides a communication device. Since the communication device provided in the embodiments of this disclosure is similar to the one described above... Figures 1 to 3 The communication method provided in the embodiments corresponds to the communication device provided in the embodiments of this disclosure, and will not be described in detail in the embodiments of this disclosure.

[0193] The communication device of this disclosure embodiment is applied to a network device. The network device configures the measurement bandwidth and subband of the carrier, communicates with the user equipment (UE) through the subband, receives the measurement values ​​of the subband fed back by the UE, and adjusts the subband configuration corresponding to the carrier according to the measurement values ​​of the subband. This realizes that the network device can reasonably adjust the subband configuration corresponding to the carrier according to the measurement values ​​of the subband fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.

[0194] With the above Figures 4 to 6 Corresponding to the communication method provided in the embodiments, this disclosure also provides another communication device. Since the communication device provided in the embodiments of this disclosure is similar to the one described above... Figures 4 to 6 The communication method provided in the embodiments corresponds to the communication device provided in the embodiments of this disclosure, and will not be described in detail in the embodiments of this disclosure.

[0195] Figure 8 This is a schematic diagram of another communication device provided in an embodiment of this disclosure. This device is applied to a user equipment.

[0196] like Figure 8 As shown, the communication device 800 includes a transceiver unit 810 and a processing unit 820.

[0197] The transceiver unit 810 is used to receive signals transmitted by the network device in the subband within the measured bandwidth based on the subband configuration.

[0198] The processing unit 820 is used to perform communication quality measurements based on the received signals to generate measurement values ​​for each sub-band corresponding to the UE;

[0199] The transceiver unit 810 is also used to send the measurement values ​​of the sub-band to the network device.

[0200] As one possible implementation of this disclosure, subband configuration is used to configure the types of multiple subbands in a carrier, wherein the subband types include uplink type, downlink type and flexible type.

It performs communication quality measurement based on the received signals to generate measurement values ​​for each subband corresponding to the UE. The measurement values ​​of the subbands are then sent to the network device. This can help the network device to reasonably adjust the subband configuration corresponding to the carrier based on the measurement values ​​of the subbands fed back by the UE, thereby avoiding the problem of mutual interference between multiple UEs.
