Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication control method, device, equipment, chip and medium. Background Art

[0002] In the field of communications, a time division duplex (TDD) cell may only need to perform downlink services. The cell may also be referred to as a rotation cell, a carrier rotation cell, or a target cell. In this case, the cell only has a downlink channel configuration, but no uplink channel configuration. The terminal cannot send downlink channel quality feedback to the network device through the uplink. If the network device needs to obtain the downlink channel quality, it can trigger the terminal to send a signal (for example, a sounding reference signal (SRS)) to estimate the downlink channel quality of the cell using the reciprocity of the TDD uplink and downlink channels. Since the cell has no uplink resources, the terminal needs to temporarily borrow the uplink resources of other cells (also referred to as source cells) to send the cell's signal, interrupting the uplink transmission of other cells in the process.

[0003] In the related art, in the carrier rotation scenario, the number of cell switching is relatively large, which causes the source cell to wait for a long time before resuming uplink transmission, affecting communication performance. Summary of the invention

[0004] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0005] To this end, the present disclosure proposes a communication control method, apparatus, communication equipment, chip and storage medium, which can effectively reduce the number of cell switching times and the waiting time of the source cell in a carrier rotation scenario, thereby improving communication performance.

[0006] An embodiment of the first aspect of the present disclosure proposes a communication control method, including: determining an initial uplink resource of a first cell, wherein the initial uplink resource is used for uplink transmission of the first cell; determining a first uplink resource based on the initial uplink resource; transmitting a first signal of a second cell based on the first uplink resource, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resource of the first cell; and maintaining the first uplink resource.

[0007] An embodiment of the second aspect of the present disclosure proposes a communication control device, including: a first determination module, used to determine the initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission of the first cell; a second determination module, used to determine the first uplink resources based on the initial uplink resources; a transmission module, used to transmit a first signal of a second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resources of the first cell; and a control module, used to maintain the first uplink resources.

[0008] The third aspect embodiment of the present disclosure proposes a communication device, including: a processor, and a memory connected to the processor in communication; the memory stores computer execution instructions; the processor executes the computer execution instructions stored in the memory to implement the communication control method proposed in the first aspect embodiment of the present disclosure.

[0009] The fourth aspect embodiment of the present disclosure proposes a chip, which includes a processing circuit and an interface circuit; wherein the interface circuit is used to read instructions, and the interface circuit sends the instructions to the processing circuit so that the processing circuit executes the communication control method proposed in the first aspect embodiment of the present disclosure.

[0010] The fifth aspect of the present disclosure provides a computer-readable storage medium, in which computer-executable instructions are stored. When the computer-executable instructions are executed by a processor, they are used to implement the communication control method as described above.

[0011] The communication control method, apparatus, communication equipment, chip and storage medium provided by the present disclosure determine the initial uplink resources of the first cell, wherein the initial uplink resources are used for the uplink transmission of the first cell, and determine the first uplink resources based on the initial uplink resources, and transmit the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell to send signals. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved.

[0025] In the embodiments of the present disclosure, the communication device may be, for example, a terminal, which is not limited.

[0026] Figure 1 FIG. 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. Figure 1As shown, the communication system 100 may include a terminal 101 and a network device 102.

[0029] In some embodiments, the technical solution of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0030] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0031] In some embodiments, the core network device may be a device including one or more network elements, or may be a plurality of devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5G Core Network, 5G CN), and a Next Generation Core (NGC).

[0032] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0033] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 For entities other than the above, the number and form of each entity are arbitrary, and the connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0034] Embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0035] In the related art, when the terminal temporarily borrows the uplink resources of the source cell to send the signal of cell 1, so that the network equipment can estimate the downlink channel quality of cell 1, it needs to switch back to the source cell and then detect whether to borrow the uplink resources of the source cell to send the signal of cell 2 (i.e., the carrier rotation scenario). In this process, the number of cell switching is relatively large, resulting in the source cell having to wait for a long time before resuming uplink transmission, thus affecting the communication performance.

[0036] The disclosed embodiments are designed to solve the above technical problems by determining the initial uplink resources of the first cell, wherein the initial uplink resources are used for uplink transmission of the first cell, and determining the first uplink resources based on the initial uplink resources, transmitting the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell to send signals. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved.

[0037] In the embodiment of the present disclosure, the first cell is, for example, the source cell mentioned above. The second cell and the third cell are, for example, the rotation cells mentioned above, or the carrier rotation cells, or the target cells.

[0038] In an embodiment of the present disclosure, the second cell and the third cell may jointly reuse the uplink resources of the first cell. The second cell transmits the first signal of the second cell (e.g., the SRS signal of the second cell) by reusing the uplink resources of the first cell. After receiving the first signal of the second cell, the network device may estimate the downlink channel quality of the second cell based on the first signal. The third cell may transmit the second signal of the third cell (e.g., the SRS signal of the third cell) by reusing the uplink resources of the first cell. After receiving the second signal of the third cell, the network device may estimate the downlink channel quality of the third cell based on the second signal.

[0039] In the embodiment of the present disclosure, the number of cells that can jointly reuse the uplink resources of the first cell can be one or more, and there is no restriction on this. In the embodiment of the present disclosure, the case where the second cell and the third cell reuse the uplink resources of the first cell is schematically described, and in the case where there are other cells (such as the fourth cell, the fifth cell, the sixth cell, and so on) that jointly reuse the uplink resources of the first cell, the processing method can refer to the description of the implementation method of the second cell and the third cell reusing the first cell, which will not be repeated here.

[0040] The resources in the embodiments of the present disclosure may refer to time domain resources and / or frequency domain resources.

[0041] The communication control method, apparatus, communication device, chip and storage medium of the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0042] The communication control method provided in the embodiments of the present disclosure may be applied in a communication device, and the communication device may be, for example, a terminal, without limitation thereto.

[0043] Figure 2 A flow chart of a communication control method provided by an embodiment of the present disclosure.

[0044] like Figure 2 As shown, the communication control method includes:

[0045] Step S201: determine initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission of the first cell.

[0046] The first cell refers to a source cell, and the first cell may be, for example, cell0. The first cell may support at least uplink transmission, and the first cell may also support downlink transmission. The resources used for uplink transmission of the first cell may be referred to as initial uplink resources. That is, the initial uplink resources are used for uplink transmission of the first cell. The initial uplink resources may be, for example, time domain resources and / or frequency domain resources, and there is no limitation on this.

[0047] In the embodiment of the present disclosure, the initial uplink resources of the first cell may be configured by a network device (eg, a base station) or may be agreed upon by a protocol, and there is no limitation on this.

[0048] In the disclosed embodiment, in the process of determining the initial uplink resources of the first cell, the initial uplink resources of the first cell may be determined based on the configuration of the network device, or based on a predefined protocol, and there is no limitation on this.

[0049] Step S202: Determine a first uplink resource according to the initial uplink resource.

[0050] After determining the initial uplink resources of the first cell, the first uplink resources can be determined. The first uplink resources refer to uplink resources used to transmit the first signal of the second cell. Since the frequency, bandwidth and other parameters of different cells are different, in order to realize the reuse of the initial uplink resources of the first cell to realize the transmission of the first signal of the second cell, the initial uplink resources can be configured accordingly, and the configured first uplink resources can support the completion of the uplink transmission of the first signal of the second cell.

[0051] The second cell refers to a rotation cell, and the second cell may be, for example, cell 1. The second cell may only support downlink transmission.

[0052] Optionally, in some embodiments, in the process of determining the first uplink resource according to the initial uplink resource, the configuration information of the second cell may be obtained, and the initial uplink resource may be configured according to the configuration information of the second cell to obtain the first uplink resource. Thus, it is possible to ensure accurate reuse of the uplink resources of the first cell to support accurate and effective uplink transmission of the first signal of the second cell, thereby ensuring communication performance.

[0053] The configuration information of the second cell is used to configure the resources of the second cell. For example, the configuration information of the second cell can be used to configure the time domain resources and / or frequency domain resources of the second cell.

[0054] The configuration information of different cells may be different.

[0055] Optionally, in some embodiments, the configuration information of the second cell includes at least one of the following: a frequency of the second cell; a bandwidth of the second cell; and a channel parameter of the second cell. Thus, the accuracy of the configuration of the first uplink resource is improved to ensure communication performance.

[0056] For example, in the process of determining the first uplink resource based on the initial uplink resource, the initial frequency corresponding to the initial uplink resource can be configured based on the frequency of the second cell; and / or the initial bandwidth corresponding to the initial uplink resource can be configured based on the bandwidth of the second cell; and / or the initial channel parameters corresponding to the initial uplink resource can be configured based on the channel parameters of the second cell; wherein the initial frequency, initial bandwidth and initial channel parameters can all be configured by the configuration information of the first cell, without limitation.

[0057] Step S203: Transmit a first signal of the second cell according to the first uplink resource, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resource of the first cell.

[0058] After determining the first uplink resource according to the initial uplink resource, the first signal of the second cell can be transmitted based on the first uplink resource. The first signal of the second cell. For example, it is the SRS signal of the second cell. The network device can receive the first signal of the second cell and estimate the downlink channel quality of the second cell based on the first signal of the second cell. For example, the network device can use the reciprocity of the TDD uplink and downlink channels and refer to the received first signal to estimate the downlink channel quality of the cell, and there is no limitation on this.

[0059] Step S204: Maintain the first uplink resource.

[0060] After completing the transmission of the first signal of the second cell, the first uplink resource can be maintained, that is, the switch back to the first cell is not immediately triggered (the "switching back to the first cell" described here can be understood as restoring the first uplink resource configured for the second cell to the initial uplink resource configured for the first cell), that is, the uplink state and / or configuration state of the first uplink resource is maintained. Therefore, in this process, cell switching is avoided, so that in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved.

[0061] In some embodiments, while maintaining the first uplink resource, a new scheduling sending event can also be detected, and based on the detection result, it can be determined whether to borrow the uplink resources of the first cell to send the second signal of other cells (i.e., the third cell), wherein the second signal of the third cell is used by the network device to determine the downlink channel quality of the third cell.

[0062] In this embodiment, by determining the initial uplink resources of the first cell, wherein the initial uplink resources are used for uplink transmission of the first cell, and determining the first uplink resources based on the initial uplink resources, transmitting the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved.

[0063] In some embodiments of the present disclosure, after maintaining the first uplink resource, if it is determined that the first signal of the second cell needs to be sent again, the first signal of the second cell can be directly transmitted again based on the first uplink resource, thereby further reducing the number of cell switching times and greatly improving communication performance.

[0064] Figure 3 A flowchart of another communication control method provided by an embodiment of the present disclosure.

[0065] like Figure 3 As shown, the communication control method includes:

[0066] Step S301: determine initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission of the first cell.

[0067] Step S302: Determine a first uplink resource according to the initial uplink resource.

[0068] Step S303: Transmit a first signal of the second cell according to the first uplink resource, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resource of the first cell.

[0069] Step S304: Maintain the first uplink resource.

[0070] For the description of steps S301 to S304, please refer to the above embodiments, which will not be repeated here.

[0071] Step S305: When uplink transmission of the first cell is required, configuration information of the first cell is obtained.

[0072] That is to say, in the embodiment of the present disclosure, after completing the transmission of the first signal of the second cell and maintaining the first uplink resource, it can be determined whether uplink transmission of the first cell is required based on the detection result of whether there is a new scheduling transmission event. If it is determined that uplink transmission of the first cell is required, switching back to the first cell can be triggered.

[0073] Optionally, in some embodiments, the configuration information of the first cell includes at least one of the following: the frequency of the first cell; the bandwidth of the first cell; and the channel parameter of the first cell, thereby supporting the improvement of the configuration accuracy of the initial uplink resources of the first cell and supporting the accurate and effective completion of the uplink transmission of the first cell.

[0074] Step S306: configure the first uplink resource according to the configuration information of the first cell to obtain the initial uplink resource.

[0075] For example, in the process of configuring the first uplink resource according to the configuration information of the first cell, the frequency corresponding to the first uplink resource can be configured based on the frequency of the first cell; and / or the bandwidth corresponding to the first uplink resource can be configured based on the bandwidth of the first cell; and / or the channel parameters corresponding to the first uplink resource can be configured based on the channel parameters of the first cell; wherein the frequency, bandwidth and channel parameters corresponding to the first uplink resource can be configured by the configuration information of the second cell, and there is no limitation on this.

[0076] Step S307: Perform uplink transmission of the first cell according to the initial uplink resources.

[0077] After the initial uplink resources are obtained, uplink transmission of the first cell can be performed according to the initial uplink resources to ensure uplink transmission of the first cell.

[0078] In this embodiment, by determining the initial uplink resources of the first cell, wherein the initial uplink resources are used for uplink transmission of the first cell, and determining the first uplink resources based on the initial uplink resources, transmitting the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved. By obtaining the configuration information of the first cell when uplink transmission of the first cell is required, configuring the first uplink resources according to the configuration information of the first cell, obtaining the initial uplink resources, and performing uplink transmission of the first cell according to the initial uplink resources, the uplink transmission of the first cell can be effectively ensured, thereby supporting the improvement of communication performance.

[0079] Figure 4 A flowchart of another communication control method provided by an embodiment of the present disclosure.

[0080] like Figure 4 As shown, the communication control method includes:

[0081] Step S401: determine initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission of the first cell.

[0082] Step S402: Determine a first uplink resource according to the initial uplink resource.

[0083] Step S403: Transmit a first signal of the second cell according to the first uplink resource, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resource of the first cell.

[0084] Step S404: Maintain the first uplink resource.

[0085] For the description of step S401 to step S404, please refer to the above embodiment for details, which will not be repeated here.

[0086] Step S405: Determine a second uplink resource according to the first uplink resource.

[0087] In the above, while maintaining the first uplink resource, the second uplink resource can be determined. The second uplink resource refers to the uplink resource used to transmit the second signal of the third cell. Since the frequency, bandwidth and other parameters of different cells are different, in order to reuse the initial uplink resource of the first cell to transmit the second signal of the third cell, the first uplink resource can be further configured, and the configured second uplink resource can support the completion of the uplink transmission of the second signal of the third cell.

[0088] The third cell refers to a rotation cell, and the third cell may be, for example, cell 2. The third cell may only support downlink transmission.

[0089] Optionally, in some embodiments, in the process of determining the second uplink resource according to the first uplink resource, the configuration information of the third cell may be obtained, and the first uplink resource may be configured according to the configuration information of the third cell to obtain the second uplink resource. Thus, it is possible to ensure accurate reuse of the uplink resources of the first cell to support accurate and effective uplink transmission of the second signal of the third cell, thereby ensuring communication performance.

[0090] The configuration information of the third cell is used to configure the resources of the third cell. For example, the configuration information of the third cell can be used to configure the time domain resources and / or frequency domain resources of the third cell.

[0091] The configuration information of different cells may be different.

[0092] Optionally, in some embodiments, the configuration information of the third cell includes at least one of the following: a frequency of the third cell; a bandwidth of the third cell; and a channel parameter of the third cell. Thus, the accuracy of the configuration of the second uplink resource is improved to ensure communication performance.

[0093] For example, in the process of determining the second uplink resource based on the first uplink resource, the frequency corresponding to the first uplink resource can be configured based on the frequency of the third cell; and / or the bandwidth corresponding to the first uplink resource can be configured based on the bandwidth of the third cell; and / or the channel parameters corresponding to the first uplink resource can be configured based on the channel parameters of the third cell; wherein the frequency, bandwidth and channel parameters corresponding to the first uplink resource can be configured by the configuration information of the second cell, without limitation.

[0094] Step S406: Transmit a second signal of the third cell according to the second uplink resource, wherein the second signal is used to determine the downlink channel quality of the third cell, and the third cell reuses the initial uplink resource of the first cell.

[0095] After determining the second uplink resource according to the first uplink resource, the second signal of the third cell can be transmitted based on the second uplink resource. The second signal of the third cell. For example, it is an SRS signal of the third cell. The network device can receive the second signal of the third cell, and estimate the downlink channel quality of the third cell based on the second signal of the third cell. For example, the network device can use the reciprocity of the TDD uplink and downlink channels and refer to the received second signal to estimate the downlink channel quality of the cell, and there is no limitation on this.

[0096] Step S407: Maintain the second uplink resource.

[0097] After completing the transmission of the second signal of the third cell, the second uplink resource can be maintained, that is, the switch back to the first cell may not be triggered immediately (the "switching back to the first cell" described here can be understood as restoring the second uplink resource configured for the third cell to the initial uplink resource configured for the first cell), that is, the uplink state and / or configuration state of the second uplink resource is maintained. Therefore, in this process, cell switching is also avoided, thereby further effectively reducing the number of cell switching times and the waiting time of the source cell, thereby improving communication performance.

[0098] In some embodiments, while maintaining the second uplink resource, a new scheduling transmission event can also be detected, and based on the detection result, it can be determined whether to borrow the uplink resources of the first cell to send signals of other cells (for example, the fourth cell, which can be another rotating cell).

[0099] In this embodiment, by determining the initial uplink resources of the first cell, wherein the initial uplink resources are used for uplink transmission of the first cell, and determining the first uplink resources based on the initial uplink resources, transmitting the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved. By determining the second uplink resource based on the first uplink resource, and transmitting the second signal of the third cell based on the second uplink resource, wherein the second signal is used to determine the downlink channel quality of the third cell, the third cell reuses the initial uplink resource of the first cell, and maintains the second uplink resource, cell switching is also avoided. Therefore, the number of cell switching times is further effectively reduced, the waiting time of the source cell is greatly reduced, and the communication performance is improved.

[0100] In some embodiments of the present disclosure, the second signal of the third cell is transmitted again according to the second uplink resource.

[0101] That is, after maintaining the second uplink resource, if it is determined that the second signal of the third cell needs to be sent again, the second signal of the third cell can be directly transmitted again according to the second uplink resource. Thus, the number of cell switching is further reduced, thereby greatly improving communication performance.

[0102] In some embodiments of the present disclosure, after maintaining the second uplink resource, if it is determined that uplink transmission of the first cell is required, configuration information of the first cell can be obtained, and the second uplink resource can be configured according to the configuration information of the first cell to obtain the initial uplink resource.

[0103] In some embodiments of the present disclosure, uplink transmission of the first cell is performed according to initial uplink resources.

[0104] For example, in the process of configuring the second uplink resource according to the configuration information of the first cell, the frequency corresponding to the second uplink resource can be configured based on the frequency of the first cell; and / or the bandwidth corresponding to the second uplink resource can be configured based on the bandwidth of the first cell; and / or the channel parameters corresponding to the second uplink resource can be configured based on the channel parameters of the first cell; wherein the frequency, bandwidth and channel parameters corresponding to the second uplink resource can be configured by the configuration information of the third cell, and there is no limitation on this.

[0105] After the initial uplink resources are obtained, uplink transmission of the first cell can be performed according to the initial uplink resources to ensure uplink transmission of the first cell.

[0106] The examples for the above embodiment are as follows:

[0107] The first cell is taken as the source cell cell0, the second cell is the rotating cell cell1, the third cell is the rotating cell cell2, and the network device is a base station. Of course, the rotating cells cell3 and cell4 may also be included, and there is no limitation to this.

[0108] In a carrier rotation (also referred to as carrier switching, specifically uplink carrier switching in the embodiment of the present disclosure), cell1 and cell2 may reuse uplink resources of cell0. The uplink resources of cell0 may be an optional example of initial uplink resources.

[0109] That is to say, in the carrier rotation scenario, multiple rotation cells can be configured to reuse the same source cell, for example, uplink transmission is configured on cell0, downlink transmission is configured on cell1 and cell2, and cell1 and cell2 only support downlink transmission. When the base station wants to estimate the downlink channel quality of these two cells, it can borrow the uplink resources of cell0 to perform SRS carrier rotation.

[0110] In the disclosed embodiment, after each rotation cell transmission is completed, there is no need to switch back to the source cell. At the same time, the switching of the next uplink resource can be determined according to the actual carrier scheduling information. If it is necessary to switch to another rotation cell next time, it can be directly switched to the new rotation cell, thereby reducing the number of handovers between cells, thereby saving handover time and reducing the uplink waiting time of the source cell.

[0111] For example, after cell0 detects that cell1 is sending, if it is determined that cell2 needs to send, it can directly switch to cell2 to send, and then switch back to cell0, as follows Figure 5 As shown, Figure 5 It is a switching diagram in the embodiment of the present disclosure. Therefore, only 3*GAP (where GAP can represent the time required for the terminal's cell switching, and the terminal can complete the cell switching within the GAP. "*" represents a multiple operation, i.e. 3 times the GAP) is needed to perform uplink transmission of the source cell, which significantly shortens the waiting time. If more (for example, 3 or more) rotating cells are configured, more waiting time for the source cell can be saved.

[0112] For example, the following steps may be included:

[0113] Step 1: It is detected in the source cell cell0 that cell1 needs to perform carrier rotation transmission, and preparations are made for the carrier rotation transmission of cell1. The uplink resources of cell0 (an optional example of initial uplink resources) are configured as the frequency, bandwidth and channel parameters of cell1 (i.e., an optional example of configuring the first uplink resources), and cell1 is sent.

[0114] Step 2: After cell1 is sent, the original uplink state (ie, maintaining an optional instance of the first uplink resource) is maintained unchanged, and a new scheduling sending event is waited for.

[0115] Step 3: If it is detected that cell2 needs to perform carrier rotation, prepare for the carrier rotation of cell2, configure the uplink resources (an optional example of the maintained first uplink resource) as the frequency, bandwidth and channel parameters of cell2 (that is, configure to obtain an optional example of the second uplink resource), and send cell2. Similarly, after cell2 completes the sending, keep the original uplink state (that is, maintain an optional example of the second uplink resource) unchanged, and wait for a new scheduling sending event.

[0116] Step 4: If it is detected that cell 1 needs to perform carrier transmission, the channel state of cell 1 is maintained and preparation is made for the next transmission of cell 1.

[0117] Step 5: If a scheduling event is detected on the source cell cell0, prepare for the carrier rotation of cell0, configure the uplink resources (an optional example of the maintained first uplink resource or the second uplink resource) as the frequency, bandwidth and channel parameters of cell0 (that is, configure an optional example of the initial uplink resource), and prepare for the next transmission of cell0.

[0118] like Figure 6 As shown, Figure 6 After performing uplink transmission of the target cell cell1, there is no need to switch back to the uplink transmission of the source cell, but wait for the next scheduling event. If required, the uplink transmission of the target cell cell2 can be performed directly.

[0120] like Figure 7 As shown, the communication control device 70 includes:

[0121] The first determination module 701 is used to determine initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission of the first cell.

[0122] The second determining module 702 is configured to determine a first uplink resource according to the initial uplink resource.

[0123] The transmission module 703 is used to transmit a first signal of the second cell according to the first uplink resource, wherein the first signal is used to determine the downlink channel quality of the second cell, and the second cell reuses the initial uplink resource of the first cell.

[0124] The control module 704 is configured to maintain the first uplink resource.

[0125] It should be noted that the above explanation of the communication control method embodiment is also applicable to the communication control device of this embodiment, and will not be repeated here.

[0126] In this embodiment, by determining the initial uplink resources of the first cell, wherein the initial uplink resources are used for uplink transmission of the first cell, and determining the first uplink resources based on the initial uplink resources, transmitting the first signal of the second cell based on the first uplink resources, wherein the first signal is used to determine the downlink channel quality of the second cell, the second cell reuses the initial uplink resources of the first cell, and maintains the first uplink resources. Since the first uplink resources are maintained after the uplink transmission of the first signal of the second cell is completed, that is to say, the configuration state of the first uplink resources will not be restored to the configuration state of the initial uplink resources, and cell switching will not be performed, but the signal of other cells (i.e., the third cell) will continue to be waited for whether to borrow the uplink resources of the first cell. Therefore, in the carrier rotation scenario, the number of cell switching times can be effectively reduced, the waiting time of the source cell can be reduced, and the communication performance can be improved.
