Description

Technical Field

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

[0002] In the field of communications, a Time Division Duplex (TDD) cell can perform only downlink services. This cell can also be referred to as a round-robin cell, carrier round-robin cell, or target cell. In this case, the cell only has downlink channel configuration, not uplink channel configuration. The terminal cannot send downlink channel quality feedback to the network device via uplink. If the network device needs to obtain downlink channel quality, it can trigger the terminal to send a signal (e.g., a Sounding Reference Signal (SRS)) to estimate the cell's downlink channel quality using the reciprocity of TDD uplink and downlink channels. Since this cell lacks uplink resources, the terminal must temporarily borrow uplink resources from other cells (also called the source cell) to transmit the cell's signal, interrupting uplink transmissions in other cells during this process.

[0003] In related technologies, in carrier round-robin scenarios, the number of cell handovers is relatively high, causing the source cell to wait a long time before it can resume uplink transmission, which affects communication performance. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

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

[0006] A first aspect of this disclosure provides a communication control method, comprising: determining initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission in the first cell; determining first uplink resources based on the initial uplink resources; transmitting 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 maintaining the first uplink resources.

[0007] A second aspect of this disclosure provides a communication control apparatus, comprising: a first determining module for determining initial uplink resources of a first cell, wherein the initial uplink resources are used for uplink transmission in the first cell; a second determining module for determining first uplink resources based on the initial uplink resources; a transmission module for transmitting 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 for maintaining the first uplink resources.

[0008] A third aspect of this disclosure provides a communication device, including: a processor and a memory communicatively connected to the processor; the memory stores computer-executable instructions; the processor executes the computer-executable instructions stored in the memory to implement the communication control method as proposed in the first aspect of this disclosure.

[0009] A fourth aspect of this disclosure provides a chip including a processing circuit and an interface circuit; wherein the interface circuit is used to read instructions and send instructions to the processing circuit so that the processing circuit executes the communication control method as proposed in the first aspect of this disclosure.

[0010] A fifth aspect of this disclosure provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, are used to implement the communication control method described above.

[0011] The communication control method, apparatus, communication equipment, chip, and storage medium disclosed herein determine the initial uplink resources of a first cell, which are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of a second cell is transmitted. 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, meaning the configuration state of the first uplink resources is not restored to the initial configuration state, no cell handover is performed. Instead, the system continues to wait to see if it can borrow the uplink resources of the first cell to transmit signals from other cells (i.e., a third cell). Therefore, in a carrier round-robin scenario, this effectively reduces the number of cell handovers and the waiting time of the source cell, thereby improving communication performance.

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.

[0025] In embodiments of this disclosure, the communication device may be, for example, a terminal, and there is no limitation thereto.

[0032] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0033] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0034] The embodiments disclosed herein can 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0035] In related technologies, when a terminal temporarily borrows uplink resources from the source cell to transmit signals from cell 1 for network equipment to estimate the downlink channel quality of cell 1, it needs to switch back to the source cell and then check whether to borrow uplink resources from the source cell to transmit signals from cell 2 (i.e., carrier round-robin scenario). During this process, the number of cell handovers is high, causing the source cell to wait a long time before resuming uplink transmission, thus affecting communication performance.

[0036] This embodiment of the disclosure aims to solve the aforementioned technical problems by determining the initial uplink resources of a first cell, which are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of the second cell is transmitted. 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 resource is maintained after the uplink transmission of the first signal of the second cell is completed, that is, the configuration state of the first uplink resource is not restored to the initial configuration state, no cell handover is performed, and the cell continues to wait for whether to borrow the uplink resources of the first cell to transmit signals from other cells (i.e., the third cell). Therefore, in a carrier round-robin scenario, the number of cell handovers can be effectively reduced, the waiting time of the source cell can be reduced, and thus the communication performance can be improved.

[0037] In embodiments of this disclosure, the first cell is, for example, the source cell mentioned above. The second and third cells are, for example, the round-robin cells, carrier round-robin cells, or target cells mentioned above.

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

[0039] In the embodiments of this disclosure, the number of cells that can share the uplink resources of the first cell can be one or more, and there is no limitation thereto. The embodiments of this disclosure illustratively describe the situation where the second cell and the third cell share the uplink resources of the first cell. However, if other cells (e.g., the fourth cell, the fifth cell, the sixth cell, and so on) also share the uplink resources of the first cell, the processing method can refer to the description of the implementation method where the second cell and the third cell share the uplink resources of the first cell, and will not be repeated here.

[0040] The resources in this disclosure may refer to time-domain resources and / or frequency-domain resources.

[0041] The following description, with reference to the accompanying drawings, describes a communication control method, apparatus, communication device, chip, and storage medium according to embodiments of the present disclosure.

[0042] The communication control method provided in this embodiment can be applied to a communication device, such as a terminal, and there is no limitation on this.

[0043] Figure 2 This is a flowchart illustrating a communication control method provided in an embodiment of the present disclosure.

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

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

[0046] Here, the first cell refers to the source cell, which can be, for example, cell0. The first cell can support at least uplink transmission, and it can also support downlink transmission. The resources of the first cell used for uplink transmission can be referred to as initial uplink resources. That is to say, the initial uplink resources are used for uplink transmission in the first cell. The initial uplink resources can be, for example, time-domain resources and / or frequency-domain resources, without limitation.

[0047] In this embodiment of the disclosure, the initial uplink resources of the first cell can be configured by network equipment (e.g., base station) or agreed upon by the protocol, and there is no restriction on this.

[0048] In this embodiment of the disclosure, the process of determining the initial uplink resources of the first cell can be 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 the first uplink resource based on the initial uplink resource.

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

[0051] The second cell refers to the round-robin cell, which can be, for example, cell1. The second cell may only support downlink transmission.

[0052] Optionally, in some embodiments, in the process of determining the first uplink resource based on 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. This ensures accurate reuse of the uplink resources of the first cell to support accurate and efficient uplink transmission of the first signal from the second cell, thus ensuring communication performance.

[0053] The configuration information for the second cell is used to configure the resources of the second cell. For example, the configuration information for 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 for different communities can be different.

[0055] Optionally, in some embodiments, the configuration information of the second cell includes at least one of the following: the frequency of the second cell; the bandwidth of the second cell; and the channel parameters of the second cell. This improves the accuracy of the configuration of the first uplink resource and ensures communication performance.

[0056] For example, in the process of determining the first uplink resource based on the initial uplink resource, the initial frequency point corresponding to the initial uplink resource can be configured based on the frequency point 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 point, initial bandwidth, and initial channel parameters can all be configured by the configuration information of the first cell, and there is no restriction on this.

[0057] Step S203: Based on the first uplink resources, transmit the first signal of the second cell, 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.

[0058] After determining the first uplink resource based on 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 is, for example, 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. For example, the network device can use the reciprocity of TDD uplink and downlink channels and refer to the received first signal to estimate the downlink channel quality of the cell; this is not limited.

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

[0060] After transmitting the first signal from the second cell, the first uplink resource can be maintained, meaning that a handover back to the first cell is not immediately triggered (the "handover back to the first cell" described here can be understood as restoring the first uplink resource configured for the second cell to its initial configuration for the first cell). This maintains the uplink state and / or configuration state of the first uplink resource. Therefore, cell handover is avoided during this process, effectively reducing the number of cell handovers and the waiting time of the source cell in carrier round-robin scenarios, thereby improving communication performance.

[0061] In some embodiments, while maintaining the first uplink resources, new scheduling transmission events can also be detected, and based on the detection results, it can be determined whether to borrow the uplink resources of the first cell to transmit 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, the initial uplink resources of the first cell are determined, whereby the initial uplink resources are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of the second cell is transmitted. 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, meaning the configuration state of the first uplink resources is not restored to the initial configuration state, no cell handover occurs. Instead, the cell continues to wait to see if it can borrow the uplink resources of the first cell to transmit signals from other cells (i.e., the third cell). Therefore, in a carrier round-robin scenario, the number of cell handovers can be effectively reduced, the waiting time of the source cell can be reduced, and communication performance can be improved.

[0063] In some embodiments of this disclosure, after maintaining the first uplink resources, if it is determined that the first signal of the second cell needs to be transmitted again, the first signal of the second cell can be transmitted again directly based on the first uplink resources. This further reduces the number of cell handovers, thereby significantly improving communication performance.

[0064] Figure 3 This is a flowchart illustrating another communication control method provided in an embodiment of this disclosure.

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

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

[0067] Step S302: Determine the first uplink resource based on the initial uplink resource.

[0068] Step S303: Based on the first uplink resources, transmit the first signal of the second cell, 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.

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

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

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

[0072] In other words, in this 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, a handover 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 parameters of the first cell. This supports improving the accuracy of the initial uplink resource configuration of the first cell and enables accurate and efficient uplink transmission of the first cell.

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

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

[0076] Step S307: Perform uplink transmission for the first cell based on the initial uplink resources.

[0077] After obtaining the initial uplink resources, uplink transmission in the first cell can be performed based on these resources to ensure uplink transmission in the first cell.

[0078] In this embodiment, the initial uplink resources of the first cell are determined, whereby the initial uplink resources are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of the second cell is transmitted. 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, meaning the configuration state of the first uplink resources is not restored to the initial configuration state, no cell handover occurs. Instead, the cell continues to wait to see if it can borrow the uplink resources of the first cell to transmit signals from other cells (i.e., the third cell). Therefore, in a carrier round-robin scenario, the number of cell handovers can be effectively reduced, the waiting time of the source cell can be reduced, and 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 resource according to the configuration information of the first cell, obtaining the initial uplink resource, and performing uplink transmission of the first cell according to the initial uplink resource, the uplink transmission of the first cell can be effectively ensured, thereby supporting the improvement of communication performance.

[0079] Figure 4 This is a flowchart illustrating another communication control method provided in an embodiment of this disclosure.

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

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

[0082] Step S402: Determine the first uplink resource based on the initial uplink resource.

[0083] Step S403: Based on the first uplink resources, transmit the first signal of the second cell, 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.

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

[0085] For a detailed description of steps S401-S404, please refer to the above embodiments, which will not be repeated here.

[0086] Step S405: Determine the second uplink resource based on the first uplink resource.

[0087] By 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 from the third cell. Since different cells have different frequency points, bandwidths, and other parameters, in order to reuse the initial uplink resource of the first cell to transmit the second signal from the third cell, the first uplink resource can be further configured. The configured second uplink resource can support the uplink transmission of the second signal from the third cell.

[0088] The third cell refers to the round-robin cell, which can be, for example, cell2. The third cell may only support downlink transmission.

[0089] Optionally, in some embodiments, in the process of determining the second uplink resource based on 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. This ensures accurate reuse of the uplink resources of the first cell to support accurate and efficient uplink transmission of the second signal from the third cell, thus ensuring communication performance.

[0090] The configuration information for the third cell is used to configure the resources of the third cell. For example, the configuration information for 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 for different communities can be different.

[0092] Optionally, in some embodiments, the configuration information of the third cell includes at least one of the following: the frequency of the third cell; the bandwidth of the third cell; and the channel parameters of the third cell. This improves the accuracy of the configuration of the second uplink resources and ensures communication performance.

[0093] For example, in the process of determining the second uplink resource based on the first uplink resource, the frequency point corresponding to the first uplink resource can be configured based on the frequency point 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 point, bandwidth, and channel parameters corresponding to the first uplink resource can all be configured by the configuration information of the second cell, and there is no restriction on this.

[0094] Step S406: Based on the second uplink resources, transmit the second signal of the third cell, wherein the second signal is used to determine the downlink channel quality of the third cell, and the third cell reuses the initial uplink resources of the first cell.

[0095] After determining the second uplink resource based on 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 is, for example, the 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 it. For example, the network device can use the reciprocity of TDD uplink and downlink channels and refer to the received second signal to estimate the downlink channel quality of the cell; this is not limited.

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

[0097] After transmitting the second signal from the third cell, the second uplink resource can be maintained. That is, a handover back to the first cell can be avoided immediately (the "handover back to the first cell" described here can be understood as restoring the second uplink resource configured for the third cell to its initial configuration for the first cell). This maintains the uplink state and / or configuration state of the second uplink resource. Therefore, cell handover is also avoided during this process, further effectively reducing the number of cell handovers and the waiting time of the source cell, thereby improving communication performance.

[0098] In some embodiments, while maintaining the second uplink resource, new scheduling transmission events can also be detected, and based on the detection result, it can be determined whether to borrow the uplink resource of the first cell to transmit signals from other cells (e.g., the fourth cell, which can be another round-robin cell).

[0099] In this embodiment, the initial uplink resources of the first cell are determined, whereby the initial uplink resources are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of the second cell is transmitted. 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, meaning the configuration state of the first uplink resources is not restored to the initial configuration state, no cell handover occurs. Instead, the cell continues to wait to see if it can borrow the uplink resources of the first cell to transmit signals from other cells (i.e., the third cell). Therefore, in a carrier round-robin scenario, the number of cell handovers can be effectively reduced, the waiting time of the source cell can be reduced, and 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, the third cell reuses the initial uplink resource of the first cell and maintains the second uplink resource, thus avoiding cell handover. Therefore, the number of cell handovers is further reduced, the waiting time of the source cell is reduced to a large extent, and the communication performance is improved.

[0100] In some embodiments of this disclosure, the second signal of the third cell is transmitted again based on the second uplink resource.

[0101] In other words, after maintaining the second uplink resources, if it is determined that the second signal of the third cell needs to be transmitted again, the second signal of the third cell can be transmitted directly based on the second uplink resources. This further reduces the number of cell handovers, thereby significantly improving communication performance.

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

[0103] In some embodiments of this disclosure, uplink transmission of the first cell is performed based on initial uplink resources.

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

[0105] After obtaining the initial uplink resources, uplink transmission in the first cell can be performed based on these resources to ensure uplink transmission in the first cell.

[0106] Examples of the above embodiments are illustrated below:

[0107] The example uses the first cell as the source cell (cell0), the second cell as the round-robin cell (cell1), the third cell as the round-robin cell (cell2), and the network device as a base station. Of course, it can also include round-robin cells (cell3 and cell4), and there are no restrictions on this.

[0108] In a carrier round-robin scenario (also known as carrier switching, specifically uplink carrier switching in this embodiment), cell1 and cell2 can reuse the uplink resources of cell0. The uplink resources of cell0 can be an optional example of the initial uplink resources.

[0109] In other words, in a carrier round-robin scenario, multiple round-robin cells can be configured to reuse the same source cell. For example, uplink transmission can be configured on cell0, while downlink transmission can be configured on cells1 and 2, with cells1 and 2 only supporting downlink transmission. When the base station needs to estimate the downlink channel quality of these two cells, it can use the uplink resources of cell0 for SRS carrier round-robin transmission.

[0110] In this embodiment of the disclosure, after each round-robin cell transmission is completed, there is no need to switch back to the source cell. At the same time, the next uplink resource handover situation can be determined based on the actual carrier scheduling information. If a handover to another round-robin cell is required next, a direct handover to the new round-robin cell can be performed, thereby reducing the number of cell handovers, saving handover time, and reducing the uplink waiting time of the source cell.

[0111] For example, if cell0 detects that cell1 has sent a message and determines that cell2 needs to send a message, it can directly switch to cell2 to send the message, and then switch back to cell0, as follows: Figure 5 As shown, Figure 5 This is a handover diagram in an embodiment of this disclosure. Therefore, by waiting only 3*GAP (where GAP represents the time required for cell handover for the terminal, and the terminal can complete the cell handover within the GAP; "*" indicates a multiplication operation, i.e., 3 times the GAP), uplink transmission from the source cell can be performed, significantly shortening the waiting time. Furthermore, if more (e.g., 3 or more) round-robin cells are configured, even more source cell waiting time can be saved.

[0112] For example, it may include the following steps:

[0113] Step 1: If it is detected that cell1 needs to perform carrier round-robin on the source cell cell0, prepare for the carrier round-robin of cell1, configure the uplink resources of cell0 (an optional example of the initial uplink resources) to the frequency point, bandwidth and channel parameters of cell1 (i.e., an optional example of the first uplink resources), and then perform the transmission of cell1.

[0114] Step 2: After cell1 has finished sending, keep the original uplink state unchanged (i.e., maintain an optional example of the first uplink resource) and wait for a new scheduled send event.

[0115] Step 3: If it is detected that cell2 needs to perform carrier round-robin, prepare for the carrier round-robin of cell2, configure the uplink resource (an optional example of the first uplink resource to be maintained) as the frequency point, bandwidth and channel parameters of cell2 (i.e., configure an optional example of the second uplink resource), and perform the transmission of cell2. Similarly, after the transmission of cell2 is completed, keep the original uplink state (i.e., keep an optional example of the second uplink resource) unchanged and wait for the new scheduling transmission event.

[0116] Step 4: If it is detected that cell1 needs to perform carrier round-robin, maintain the channel state of cell1 and prepare for the next transmission of cell1.

[0117] Step 5: If a scheduling event is detected on cell0 of the source cell, prepare for carrier round-robin transmission of cell0. Configure the uplink resources (an optional example of the first uplink resources or the second uplink resources maintained) as the frequency, bandwidth and channel parameters of cell0 (i.e., an optional example of configuring the initial uplink resources) to prepare for the next transmission of cell0.

[0118] like Figure 6 As shown, Figure 6 This is a schematic diagram of uplink transmission in an embodiment of this disclosure. After uplink transmission to target cell cell1 is performed, there is no need to switch back to uplink transmission to the source cell. Instead, it waits for the next scheduling event. If required, uplink transmission to target cell cell2 can be performed directly.

[0119] Figure 7 This is a schematic diagram of the structure of a communication control device provided in an embodiment of this disclosure.

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

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

[0122] The second determining module 702 is used to determine the first uplink resource based on 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 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.

[0124] Control module 704 is used to maintain the first uplink resource.

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

[0126] In this embodiment, the initial uplink resources of the first cell are determined, whereby the initial uplink resources are used for uplink transmission in the first cell. Based on the initial uplink resources, a first uplink resource is determined, and based on the first uplink resource, a first signal of the second cell is transmitted. 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, meaning the configuration state of the first uplink resources is not restored to the initial configuration state, no cell handover occurs. Instead, the cell continues to wait to see if it can borrow the uplink resources of the first cell to transmit signals from other cells (i.e., the third cell). Therefore, in a carrier round-robin scenario, the number of cell handovers can be effectively reduced, the waiting time of the source cell can be reduced, and communication performance can be improved.
