DETAILED DESCRIPTION

The present disclosure provides an available network system which, as shown inFIG.1, includes a UE11, a first network side device12, a second network side device13and a central control unit14. The UE11may be a mobile phone, a tablet personal computer, a laptop computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID) or a wearable device. It should be appreciated that, the type of the UE11will not be particularly defined herein. The UE11may communication with the first network side device12and the second network side device13simultaneously. The first network side device12may be a network side device in a first system, e.g., a base station in the first system, and the base station may be a macro base station, e.g., an evolved Node B (eNB) in an LTE system or a gNB in a 5G New Radio (NR) system. In addition, the first network side device12may also be an Access Point (AP). The second network side device13may be a network side device in a second system, e.g., a base station in the second system, and the base station may be a macro base station, e.g., the eNB in the LTE system or the gNB in the 5G NR system. It should be appreciated that, the types of the first network side device12and the second network side device13will not be particularly defined herein. In addition, the first system may be the LTE system while the second system may be the 5G NR system, or the first system may be the 5G NR system while the second system may be the LTE system. In some embodiments of the present disclosure, the first system and the second system may be tightly coupled with each other in a Dual Connectivity (DC) mode. One of the two system may serve as a Master Node (MN), and the other may serve as a Secondary Node (SN). In a DC system, two cell groups, i.e., a Master Cell Group (MCG) and a Secondary Cell Group (SCG), may be provided. The MCG may include a Primary Cell (PCell) and one or more Secondary Cell (SCell). The SCG may include one Primary Secondary Cell (PSCell) and one or more SCells. The central control unit14may be deployed in the first network side device, the second network side device or any other network node, which will not be particularly defined herein.

In the above network system, data transmission may be performed between the UE11and the first network side device12as well as the second network side device13simultaneously, or at different time points, which will not be particularly defined herein.

The present disclosure provides in some embodiments a resource information transmission method for a first network side device which, as shown inFIG.2, includes the following steps.

Step201: acquiring resource information from a second network side device or a central control unit, the resource information being used to represent a frequency-domain resource for the second network side device or the first network side device.

A carrier frequency for the second network side device may be a frequency-domain resource to be scheduled by the second network side device, e.g., a frequency-domain resource or a time-frequency-domain resource. In this way, the first network side device may perform the information delivery in accordance with the frequency-domain resource to be scheduled by the second network side device, so as to prevent the occurrence of an intra-UE interference for a UE.

The frequency-domain resource for the first network side device may be allocated by the central control unit. The central control unit may configure the frequency-domain resource so as to prevent the occurrence of the intra-UE interference for the UE. In other words, when the first network side device performs the information delivery on the frequency-domain resource, it is able to prevent the occurrence of the intra-UE interference for the UE.

It should be appreciated that, in the embodiments of the present disclosure, the frequency-domain resource may be a frequency-domain resource without any time information, or a frequency-domain resource with time information, i.e., a time-frequency-domain resource.

In the embodiments of the present disclosure, the intra-UE interference may refer to an interference caused by a signal transmitted by the UE itself on a signal received by the UE itself, e.g., an interference caused by an uplink signal transmitted by the UE on a downlink signal received by the UE. In addition, the intra-UE interference may include, but not limited to, intermodulation interference, harmonic interference or harmonic combination interference. The harmonic interference may be a secondary harmonic interference or any other high-order harmonic interference, and the intermodulation interference may be a secondary intermodulation interference or any other high-order intermodulation interference, which will not be particularly defined herein.

For example, when the first network side device is a network side device in the LTE system, the second network side device is a network side device in the 5G NR system, and the LTE system and the 5G NR system are coupled in the DC mode using an LTE Frequency Division Duplexing (FDD) frequency of 1.8 GHz and an NR Time Division Duplexing (TDD) frequency of 3.5 GHz, as shown inFIG.3, the UE may communicate with an LTE base station and an NR base station, i.e., the UE may transmit an uplink signal to the LTE base station at the frequency of 1.8 GHz and receive a downlink signal from the 5G NR base station at the frequency of 3.5 GHz. In this regard, the intra-UE interference may be caused by the uplink signal on the downlink signal, i.e., the uplink signal may be an interference source link, while the downlink signal may be an interfered link.

For another example, when the first network side device is a network side device in the LTE system, the second network side device is a network side device in the 5G NR system, and the LTE system and the 5G NR system are coupled in the DC mode using an LTE FDD frequency of 1.8 GHz and an NR TDD frequency of 3.5 GHz, as shown inFIG.4, the UE may communicate with the LTE base station and the NR base station, i.e., the UE may transmit an uplink signal to the LTE base station at the frequency of 1.8 GHz, and meanwhile transmit an uplink signal to the NR base substrate at the frequency of 3.5 GHz and receive a downlink signal from the LTE base station at the frequency of 1.8 GHz. In this regard, the intra-UE interference may be caused by each of the two uplink signals on the downlink signal, i.e., each of the two uplink signals may be an interference source link, while the downlink signal may be an interfered link.

Step202: performing communication transmission with the UE in accordance with the resource information.

In this step, the first network side device may perform the communication transmission with one or more UEs, or with one or more UEs in one or more cells in accordance with the resource information. In other words, the resource information may be resource information at a UE level or at a cell level.

Through the above steps, it is able to achieve the interaction of the resource information between the first network side device and the second network side device, thereby to reduce or prevent the occurrence of the intra-UE interference for the UE. In addition, it is able to achieve the interaction of the resource information between the first network side device and the central control unit, thereby to reduce or prevent the occurrence of the intra-UE interference for the UE. For example, in Step202, the first network side device may perform the communication transmission with the UE on a frequency-domain resource of the frequency-domain resources for the second network side device, which is without any intra-UE interference. Alternatively, when uplink transmission is currently being performed between the second network side device (e.g., the network side device in the LTE system) and the UE, no downlink transmission may be performed between the first network side device and the UE in Step202, or when the uplink transmission is currently being performed between the second network side device (e.g., the network side device in the 5G NR system) and the UE, the uplink transmission and the downlink transmission may not be performed by the first network side device simultaneously.

In the embodiments of the present disclosure, through resource coordination between the first network side device and the second network side device, it is able to reduce the interference for the UE, thereby to improve the communication performance of the UE.

As shown inFIG.5, the present disclosure further provides in some embodiments a resource information transmission method for a first network side device, which differs from that inFIG.2mainly in that the resource information is transmitted by the second network side device. As shown inFIG.5, the resource information transmission method may include the following steps.

Step501: acquiring the resource information from the second network side device, the resource information being used to represent a frequency-domain resource for the second network side device.

In a possible embodiment of the present disclosure, the resource information may be used to represent at least one of: a frequency-domain resource for uplink transmission and/or downlink transmission to be scheduled by the second network side device for a target UE or a target cell; a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; a scheduling priority level of a frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell; a scheduling priority level of a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; a frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell, as well as transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range corresponding to the frequency-domain resource; a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell, as well as transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range corresponding to the time-frequency-domain resource, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; a time-frequency-domain resource occupied by a significant uplink signal and/or a significant uplink channel for the second network side device, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; and a time-frequency-domain resource occupied by a significant downlink signal and/or a significant downlink channel for the second network side device, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located.

The frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell may be a frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell within a predetermined time period. The time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell may be a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the second network side device for the target UE or the target cell within a predetermined time period.

In addition, the frequency-domain resource represented by the resource information may include one or more of a Physical Resource Block (PRB), a bandwidth part, a PRB group, a subcarrier, a system bandwidth of a component carrier, and a central frequency point.

In this regard, it is able to enrich reference resources when the communication transmission is performed between the first network side device and the UE, thereby to prevent the occurrence of the intra-UE interference for the UE. In addition, the resource information may also be used to represent a serial number of the subcarrier, bandwidth information about the subcarrier, or any other information, which will not be particularly defined herein.

For example, the resource information may be used to represent PRB index, a system bandwidth and a central frequency point to be scheduled by the second network side device within a subsequent time period of 200 ms, i.e., the PRB index to be scheduled within the subsequent time period of 200 ms may be 10 to 20, the system bandwidth may be 20 MHz and the central frequency point may be 1800 MHz.

The scheduling priority level of the frequency-domain resource may be a priority level of each frequency-domain resource, and the scheduling priority level of the time-frequency-domain resource may be a priority level of each time-frequency-domain resource. For example, the resource information may be used to represent the PRB index to be scheduled by the second network side device whose priority levels are ranked in a descending order within the subsequent time period of 200 ms, the system bandwidth and the central frequency point, i.e., the PRB index to be scheduled within the subsequent time period of 200 ms may be 100 to 1, the system bandwidth may be 20 MHz and the central frequency point may be 1800 MHz.

The transmission power, the transmission power range, the transmission power spectrum density or the transmission power spectrum density range corresponding to the frequency-domain resource may be transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range used when the second network side device performs the communication transmission on the frequency-domain resource. Identically, the transmission power, the transmission power range, the transmission power spectrum density or the transmission power spectrum density range corresponding to the time-frequency-domain resource may be transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range used when the second network side device performs the communication transmission on the time-frequency-domain resource. For example, the resource information may be used to represent the PRB index to be scheduled by the second network side device within the subsequent time period of 200 ms, the system bandwidth and the central frequency point, i.e., the PRB index to be scheduled within the subsequent time period of 200 ms may be 10 to 20, the transmission power range may be 5 dBm to 10 dBm, the system bandwidth may be 20 MHz and the central frequency point may be 1800 MHz.

The significant uplink signal may include an uplink reference signal, e.g., a Sounding Reference Signal (SRS), a Common Reference Signal (CRS) or a Positioning Reference Signal (PRS). Of course, apart from the reference signal, the significant uplink signal may also include an uplink signal defined by the second network side device, or defined by the second network side device through negotiation, which will not be particularly defined herein. In addition, the significant uplink signal may also be an uplink signal for a Multicast Broadcast Single Frequency Network (MBSFN).

The significant uplink channel may include one or more of an uplink control channel and a Physical Random Access Channel (PRACH). The uplink control channel may include a Physical Uplink Control Channel (PUCCH) or any other uplink control channel, which will not be particularly defined herein.

The significant downlink signal may include one or more of a synchronization signal, a paging signal and a downlink reference signal.

The synchronization signal may include a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS). The downlink reference signal may include a Channel State Information Reference Signal (CSI-RS) or a Demodulation Reference Signal (DMRS). Alternatively, the significant downlink signal may also include a downlink signal defined by the second network side device, or defined by the second network side device through negotiation, which will not be particularly defined herein. In addition, the significant downlink signal may also be a downlink signal for the MBSFN.

The significant downlink channel may include one or more of a broadcast channel, a downlink control channel, a downlink shared channel, a Physical Hybrid Automatic Repeat-reQuest Indicator Channel (PHICH) and a Physical Control Format Indicator Channel (PCFICH).

The broadcast channel may include a Physical Broadcast Channel (PBCH), the downlink control channel may be a Physical Downlink Control Channel (PDCCH), and the downlink shared channel may be a Physical Downlink Shared Channel (PDSCH).

During the implementation, the frequency-domain resource to be scheduled by the second network side device may be represented by the resource information, so it is able for the first network side device to accurately determine a transmission resource on which the intra-UE interference is probably caused, thereby to reduce or prevent the occurrence of the intra-UE interference for the UE.

Step502: performing communication transmission with the UE in accordance with the resource information.

Step502may include, when uplink transmission is performed between the second network side device and the UE, not performing, by the first network side device, downlink transmission with the UE, or not performing, by the first network side device, the uplink transmission and the downlink transmission simultaneously.

In a possible embodiment of the present disclosure, the performing the communication transmission with the UE in accordance with the resource information may include: determining a first transmission resource for the target UE probably influenced by the intra-UE interference in accordance with the resource information, and scheduling a transmission resource other than the first transmission resource preferentially so as to perform the communication transmission with the UE; or determining a second transmission resource for a UE in the target cell probably influenced by the intra-UE interference in accordance with the resource information, and scheduling a transmission resource other than the second transmission resource preferentially so as to perform the communication transmission with the UE in the target cell.

The determining the first transmission resource for the target UE probably influenced by the intra-UE interference may include determining frequency point information about the target UE probably influenced by the intra-UE interference. For example, the frequency point information about the target UE probably influenced by such intra-UE interference as intermodulation interference or secondary harmonic interference may be determined as follows. When the UE accesses to the LTE system and the NR system in a DC mode, an LTE uplink frequency point is 1720 MHz to 1740 MHz, and a 5G NR uplink frequency point is 3485 MHz to 3525 MHz, a frequency point range for the UE probably influenced by the intermodulation interference may be an LTE downlink frequency point, i.e., 1745 MHz to 1805 MHz. Then, in combination with the LTE system bandwidth and the central frequency point at a network side (e.g., the LTE system bandwidth is 1765 MHz to 1775 MHz), the frequency point for the UE probably influenced by the intermodulation interference may be 1765 MHz to 1775 MHz. For another example, when the LTE uplink frequency point is 1720 MHz to 1740 MHz, a frequency point for the UE probably influenced by the secondary harmonic interference may be a 5G downlink frequency point, i.e., 3440 MHz to 3480 MHz. Then, in combination with the NR system bandwidth and the central frequency point at the network side (e.g., the NR system bandwidth is 3460 MHz to 3500 MHz), the frequency point for the UE probably influenced by the secondary harmonic interference may be 3460 MHz to 3480 MHz.

Identically, the second transmission resource for the UE in the target cell probably influenced by the intra-UE interference may be determined.

In the embodiments of the present disclosure, it is able to preferentially schedule the transmission resource other than the transmission resource probably influenced by the intra-UE interference so as to perform the communication transmission with the UE in the target cell, thereby to prevent the intra-UE interference.

In a possible embodiment of the present disclosure, the first transmission resource may include one or more of a PRB, a bandwidth part, a PRB group, a subcarrier, a system bandwidth of a component carrier, and a central frequency point. The second transmission resource may include one or more of a PRB, a bandwidth part, a PRB group, a subcarrier, a system bandwidth of a component carrier, and a central frequency point.

Through the first transmission resource and the second transmission resource, it is able for the first network side device to accurately schedule the resource not influenced by the intra-UE interference for the transmission, thereby to improve the communication performance of a communication system.

It should be appreciated that, in the embodiments of the present disclosure, Step302may further include performing the communication transmission with the UE in accordance with the resource information through a transmission resource adjacent to the time-frequency-domain resource represented by the resource information, or through a transmission resource other than the time-frequency-domain resource represented by the resource information, which will not be particularly defined herein.

According to the embodiments of the present disclosure, through the above steps, it is able for the first network side device to perform the communication transmission with the UE in accordance with the transmission resource to be scheduled by the second network side device, thereby to prevent the intra-UE interference for the UE.

As shown inFIG.6, the present disclosure further provides in some embodiments a resource information transmission method for a first network side device. The resource information transmission method inFIG.6differs from that inFIG.2mainly in that the resource information is received by the first network side device from the central control unit. As shown inFIG.6, the resource information transmission method may include the following steps.

Step601: acquiring the resource information from the central control unit, the resource information being used to represent the frequency-domain resource for the first network side device.

In a possible embodiment of the present disclosure, the resource information may be used to represent at least one of: a frequency-domain resource for uplink transmission and/or downlink transmission to be scheduled by the first network side device for a target UE or a target cell; a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the first network side device for the target UE or the target cell, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; a scheduling priority level of a frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the first network side device for the target UE or the target cell; a scheduling priority level of a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the first network side device for the target UE or the target cell, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located; a frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the first network side device for the target UE or the target cell, as well as transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range corresponding to the frequency-domain resource; a time-frequency-domain resource for the uplink transmission and/or the downlink transmission to be scheduled by the first network side device for the target UE or the target cell, as well as transmission power, a transmission power range, a transmission power spectrum density or a transmission power spectrum density range corresponding to the time-frequency-domain resource, the time-frequency-domain resource including a frequency-domain resource and a time-domain resource where the frequency-domain resource is located.

The description about the frequency-domain resource represented by the resource information may refer to that mentioned in the above embodiment as shown inFIG.3with a same beneficial effect, and thus will not be particularly defined herein.

In a possible embodiment of the present disclosure, the resource represented by the resource information may be a resource configured by the central control unit to prevent the occurrence of the intra-UE interference for the target UE or the UE in the target cell. For example, the central control unit may configure the resources capable of preventing the occurrence of the intra-UE interference for the first network side device and the second network side device, i.e., when the first network side device performs the transmission with the UE through a corresponding transmission resource and the second network side device performs the transmission with the UE through a corresponding transmission resource, no intra-UE interference may occur for the UE.

For example, the resource information may be used to represent PRB index to be scheduled by the first network side device within a subsequent time period of 200 ms, a system bandwidth and a central frequency point, i.e., the PRB index to be scheduled within the subsequent time period of 200 ms may be 11 to 20. The resource information transmitted from the central control unit to the second network side device may be used to represent PRB index to be scheduled by the second network side device within the subsequent time period of 200 ms, a system bandwidth and a central frequency point, i.e., the PRB index to be scheduled within the subsequent time period of 200 ms may be 1 to 10.

For another example, the resource information may be used to represent the PRB index to be scheduled by the first network side device whose priority levels are ranked in a descending order within the subsequent time period of 200 ms (e.g., 100 to 1), and the resource information transmitted from the central control unit to the second network side device may be used to represent the PRB index to be scheduled by the second network side device whose priority levels are ranked in a descending order within the subsequent time period of 200 ms (e.g., 1 to 100).

For yet another example, the resource information may be used to represent the PRB index to be scheduled by the first network side device within the subsequent time period of 200 ms (11 to 20) and the transmission power range (5 dBm to 10 dBm), and the resource information transmitted from the central control unit to the second network side device may be used to represent the PRB index to be scheduled by the second network side device within the subsequent time period of 200 ms (1 to 10) and the transmission power range (5 dBm to 10 dBm).

In a possible embodiment of the present disclosure, the frequency-domain resource represented by the resource information may include one or more of a PRB, a bandwidth part, a PRB group, a subcarrier, a system bandwidth of a component carrier, and a central frequency point.

The description about the frequency-domain resource may refer to that mentioned in the above embodiment as shown inFIG.3with a same beneficial effect, and thus will not be particularly defined herein.

Step602: performing communication transmission with the UE in accordance with the resource information.

In a possible embodiment of the present disclosure, the performing the communication transmission with the UE in accordance with the resource information may include performing the communication transmission with the target UE or the UE in the target cell through the resource represented by the resource information.

During the implementation, it is able for the first network side device to perform the communication transmission with the target UE or the UE in the target cell through the resource configured by the central control unit, thereby to prevent the occurrence of the intra-UE interference for the UE.

According to the embodiments of the present disclosure, through the above steps, it is able for the first network side device to perform the communication transmission with the UE through the frequency-resource configured by the central control unit, thereby to prevent the occurrence of the intra-UE interference for the UE.
