Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a method, apparatus, and device for resource allocation. Background Art

[0002] With the development of communication technology, the application of communication technology is becoming more and more extensive, and communication technology is closely related to people's lives. When a user needs to perform a service, the sounding reference signal (SRS) can measure the uplink channel quality. Specifically, SRS can perform frequency selective scheduling, power control and timing advance functions for user equipment (UE), and then the UE can complete the required service according to the allocated SRS resources.

[0003] However, when there are a large number of UEs in a cell, the SRS resources allocated to multiple UEs cannot meet the needs of all UEs, which will lead to inaccurate measurements of uplink and downlink channels, thereby reducing the performance of uplink and downlink transmissions, for example, increasing the bit error rate of transmitted data, data loss or reducing cell throughput. Summary of the invention

[0004] The embodiments of the present application provide a method, apparatus and device for resource allocation, which improves the accuracy of uplink and downlink channel measurement while ensuring that all user equipment can be allocated SRS resources, thereby improving the performance of uplink and downlink transmission, for example, reducing the bit error rate of transmitted data and improving cell throughput.

[0005] A first aspect of an embodiment of the present application provides a method for resource allocation, including:

[0006] The access network device sends first SRS resource allocation information to the first user equipment, the first SRS resource allocation information indicates the first SRS resource, wherein the period of the first SRS resource is the first period, and then the access network device sends second SRS resource allocation information to the first user equipment, the second SRS resource allocation information indicates the second SRS resource, the period of the second SRS resource is the second period, the second period is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, wherein the first user equipment is a large-packet user equipment.

[0007] In an embodiment of the present application, when there are a large number of users in a cell, in the case of allocating periodic SRS resources to large-packet user equipment, at least one of semi-static SRS resources or non-periodic SRS resources is also allocated to the large-packet user equipment, ensuring that resources are allocated to large-packet user equipment first, thereby ensuring that the user equipment can be allocated SRS resources, thereby improving the uplink and downlink (beam forming, BF) performance of the user equipment, and improving the accuracy of uplink and downlink channel measurement, thereby improving the performance of uplink and downlink transmission, for example, reducing the bit error rate of transmitted data and improving cell throughput.

[0008] In combination with the first aspect of the embodiments of the present application, in a first implementation method of the first aspect of the embodiments of the present application, a large-packet user equipment is a user equipment whose average service data volume within a time range is greater than or equal to a target threshold.

[0009] In combination with the first aspect of the embodiments of the present application or any one of the first implementation methods of the first aspect of the embodiments of the present application, in the second implementation method of the first aspect of the embodiments of the present application, the access network device determines whether the first user device is a large-packet user device based on the amount of service data of the first user device within a time range.

[0010] In an embodiment of the present application, by counting the amount of service data of the user equipment within a time range, it is determined whether the user equipment is a large-packet user equipment. Secondly, since the large-packet user equipment is a user equipment with a relatively large amount of service data, after the large-packet user equipment is determined, semi-static SRS resources or non-periodic SRS resources can be sent to it, so that the large-packet user equipment can still obtain better BF performance when there are more user equipment, thereby improving the performance of uplink and downlink transmission, thereby improving the feasibility of the present application.

[0011] In combination with the first aspect of the embodiments of the present application or any one of the first implementation methods of the first aspect of the embodiments of the present application, in the third implementation method of the first aspect of the embodiments of the present application, the access network device is a target access network device, and the access network device receives a switching message from a source access network device, wherein the switching message includes information for indicating that the first user device is a large-packet user device.

[0012] In an embodiment of the present application, the access network device can indicate whether the first user device is a large-packet user device based on the information included in the switching message, and can also be promptly determined as a large-packet user device during the movement of the first user device, thereby sending semi-static SRS resources or non-periodic SRS resources in a timely manner, thereby improving the efficiency of resource allocation and thus improving the feasibility of the present application.

[0013] In combination with any one of the first aspect of the embodiments of the present application to the third implementation method of the first aspect of the embodiments of the present application, in the fourth implementation method of the first aspect of the embodiments of the present application, the access network device sends second SRS resource allocation information to the second user equipment, the second user equipment is a large packet user equipment, and secondly, the access network device activates the second SRS resource for the first user equipment or the second user equipment at the same time.

[0014] In combination with the fourth implementation method of the first aspect of the embodiment of the present application, in the fifth implementation method of the first aspect of the embodiment of the present application, when the second SRS resource is activated for the first user equipment, the access network device starts a timer. When the timer expires, the access network device deactivates the second SRS resource for the first user equipment and activates the second SRS resource for the second user equipment.

[0015] In an embodiment of the present application, this embodiment can allocate only one set of semi-static SRS resources to each user device. When a conflict occurs in the semi-static SRS resources, a timer can be used to rotate the activation of the semi-static SRS resources among the user devices to ensure that service demand is improved and the uplink and downlink BF performance of the user device is improved. Secondly, RRC signaling reconfiguration can be avoided, saving RRC signaling reconfiguration overhead.

[0016] In combination with any one of the first aspect of the embodiment of the present application to the third implementation manner of the first aspect of the embodiment of the present application, in a sixth implementation manner of the first aspect of the embodiment of the present application, the second SRS resource information further indicates a third SRS resource, the period of the third SRS resource is a third period, and the third period is shorter than the first period and further includes:

[0017] The access network device sends second SRS resource allocation information to the second user equipment, where the second user equipment is a large packet user equipment;

[0018] When the access network device activates the second SRS resource for the first user equipment, the third SRS resource is activated for the second user equipment; or, when the access network device activates the third SRS resource for the first user equipment, the second SRS resource is activated for the second user equipment.

[0019] In the embodiment of the present application, it can be achieved that the activated semi-static SRS resources can be activated by the access network device and used by the user equipment in conflict, thereby reducing RRC signaling reconfiguration and thus saving RRC signaling overhead.

[0020] A second aspect of an embodiment of the present application provides a method for resource allocation, including:

[0021] The first user equipment receives first SRS resource allocation information from the access network equipment, the first SRS resource allocation information indicates a first SRS resource, wherein the period of the first SRS resource is a first period, and the first user equipment also receives second SRS resource allocation information from the access network equipment, the second SRS resource allocation information indicates a second SRS resource, the period of the second SRS resource is a second period, the second period is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, wherein the first user equipment is a large-packet user equipment.

Further, when the first user device is a large-packet user device, the first user device can also receive at least one of semi-static SRS resources or non-periodic SRS resources from the access network device, thereby ensuring that large-packet user devices are allocated resources first, thereby ensuring that the user devices can be allocated SRS resources, thereby improving the uplink and downlink BF performance of the user devices, and improving the uplink and downlink channel measurement accuracy, thereby improving the uplink and downlink transmission performance, for example, reducing the bit error rate of transmitted data and improving cell throughput.

[0076] Further, the resource allocation method used in the embodiment of the present application will be described in detail below with the access network device as the execution subject, please refer to Figure 3 , Figure 3 A schematic diagram of an embodiment of a method for resource allocation in an embodiment of the present application.

[0077] 101. An access network device sends first SRS resource allocation information to a first user equipment, where the first SRS resource allocation information indicates a first SRS resource, wherein a period of the first SRS resource is a first period;

[0078] In this embodiment, the access network device may first send first SRS resource allocation information to the first user equipment. The first SRS resource allocation information may indicate a first SRS resource, and a period of the first SRS resource is a first period.

[0079] Specifically, the first SRS resource can be a periodic SRS resource, and the periodic SRS resource can be configured to the first user equipment through radio resource controller (RRC) signaling. After the periodic SRS resource is configured for the first user equipment, the resource has been activated and no other signaling triggering is required. Furthermore, the periodic SRS resource can also be periodically sent to the first user equipment, and different first periods can be configured based on the number of users in the cell. It should be understood that in actual applications, the first period can be but not limited to 5ms, 10ms, 20ms, 40ms, 320ms or 640ms.

[0080] 102. The access network device sends second SRS resource allocation information to the first user equipment, where the second SRS resource allocation information indicates a second SRS resource, the period of the second SRS resource is a second period, the second period is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, wherein the first user equipment is a large-packet user equipment.

[0081] In this embodiment, the access network device may further send second SRS resource allocation information to the first user equipment, and the second SRS resource allocation information may indicate a second SRS resource. When the second SRS resource is a periodic SRS resource, the period of the second SRS resource may be a second period, and the second period is shorter than the first period. Alternatively, the second SRS resource may be a non-periodic SRS resource. The first user equipment is a large packet user equipment.

[0082] Specifically, when the second SRS resource is a periodic SRS resource, the second SRS resource in the present application can be specifically a semi-static SRS resource. The semi-static SRS resource is similar to the periodic SRS resource and can be configured to the first user equipment through RRC signaling. However, unlike the periodic SRS resource, after the first user equipment configures the semi-static SRS resource, the resource has not been activated yet, and the semi-static SRS resource needs to be activated through the media access control layer control element (MAC CE) signaling. The activated semi-static SRS resource can be equivalent to the periodic SRS resource, and the semi-static SRS resource configured in a cell is limited. After the semi-static SRS resource is used by the first user equipment, it is also necessary to deactivate the semi-static SRS resource through MAC CE signaling. The semi-static SRS resource can be released after being deactivated and then used by other user equipment. It should be understood that in actual applications, the second period corresponding to the semi-static SRS resource can be, but not limited to, 5ms, 10ms, 20ms or 40ms, but the second period is smaller than the first period.

[0083] Secondly, the second SRS resource can also be a non-periodic SRS resource. The non-periodic SRS resource can be configured to the first user equipment through RRC signaling. After the first user equipment configures the non-periodic SRS resource, the non-periodic SRS resource has not been activated yet, and it is necessary to trigger the non-periodic SRS resource of the first user equipment through the downlink control information (downlink control information, DCI) of the physical downlink control channel (physical downlink control channel, PDCCH). Specifically, the PDCCH DCI can identify the identifier carried by the service packet of the user equipment, and then trigger the non-periodic SRS resource, indicating that the non-periodic SRS resource is available, and the non-periodic SRS resource can only be used once and does not need to be deactivated.

[0084] For easier understanding, see Figure 4A , Figure 4B as well as Figure 4C , Figure 4A , Figure 4B as well as Figure 4C They are schematic diagrams of resource allocation in the embodiments of the present application, such as Figure 4A As shown, Figure 4A In the example, user equipment 1 and user equipment 3 are large-packet user equipments, and the access network device can allocate periodic SRS resources and semi-static SRS resources to user equipment 1 and user equipment 3. Figure 4B As shown, user equipment 1 and user equipment 3 are large-packet user equipments, and the access network device can allocate periodic SRS resources and non-periodic SRS resources to user equipment 1 and user equipment 3. Further, in another possibility, as Figure 4C As shown, user equipment 1 is a large packet user equipment, and the access network device can allocate periodic SRS resources, semi-static SRS resources and non-periodic SRS resources to user equipment 1. It should be noted that: FIG. 4A to FIG. 4C The period corresponding to the semi-static SRS resource can be shorter than the period length corresponding to the periodic SRS resource. Therefore, when there are a large number of users in a cell, when allocating periodic SRS resources to large-packet user equipment, at least one of the semi-static SRS resources or the non-periodic SRS resources is also allocated to the large-packet user equipment to ensure that the large-packet user equipment is allocated resources first, thereby ensuring that the user equipment can be allocated SRS resources, and the uplink and downlink BF performance of the user equipment is improved, and the uplink and downlink channel measurement accuracy is improved, thereby improving the performance of uplink and downlink transmission, for example, reducing the bit error rate of the transmitted data and improving the cell throughput.

[0085] Optionally, the large-packet user equipment is a user equipment whose average service data volume within a time range is greater than or equal to a target threshold.

[0086] It should be understood that in actual applications, a large-packet user device may also be a service data flow with a maximum or minimum value within a time range, or a comparison between a value obtained by calculation and a target threshold value for the service data volume within a time range. The present application uses the average service data volume to determine the large-packet user device, which should not be understood as a limitation of the present application.

[0087] Furthermore, the access network device may determine whether the first user equipment is a large-packet user equipment according to the amount of service data of the first user equipment within a time range.

[0088] Exemplarily, the access network device can determine whether the first user equipment is a large packet user equipment through a service identification strategy. For example, first, the access network device can configure the judgment threshold in the device large packet service identification strategy to be A, and A can be 1Mbyte. It should be understood that in actual applications, A can be configured for the access network device according to the number of users and the number of resources in the cell, and the specific value of A should not be used as a limitation of this application. Then the access network device can count the average throughput of each bearer within a time range, and the average throughput can be a traffic handling priority (THP). When THP is greater than or equal to the judgment threshold A, that is, the amount of service data within a time range of the user equipment is greater than or equal to the judgment threshold A, the access network device can determine that the user equipment is a large packet user equipment, and the service attribute flag information is "1", that is, a large packet user identification. On the contrary, when THP is less than the judgment threshold A, that is, the amount of service data within a time range of the user equipment is less than the judgment threshold A, the access network device can determine that the user equipment is a non-large packet user equipment, and the service attribute flag information is "0", that is, a non-large packet user identification. Therefore, before allocating resource information to the user equipment, it is determined whether the user equipment is a large-packet user equipment by counting the amount of service data of the user equipment within a time range. Secondly, since the large-packet user equipment is a user equipment with a relatively large amount of service data, after the large-packet user equipment is determined, semi-static SRS resources or non-periodic SRS resources can be sent to it, so that the large-packet user equipment can still obtain better BF performance when there are more user equipment, thereby improving the performance of uplink and downlink transmission, thereby improving the feasibility of the present application.

[0089] Optionally, when the access network device is the target access network device, the access network device may receive a switching message from the source access network device, where the switching message includes information indicating that the first user equipment is a large-packet user equipment.

[0090] Specifically, when the first user device is in a moving state, for example, the first user device is in a moving vehicle, since the vehicle is usually moving in real time and at high speed, and the first user device may switch in different cells in a short time, that is, if the access network device is unable to timely determine whether the first user device is a large-packet user device only through the aforementioned service identification strategy, when the first user device switches from the source access network device to the target access network device, the target access network device can receive a switching message, and the switching message includes information for indicating that the first user device is a large-packet user device, that is, the aforementioned large-packet user identifier, and the target access network device can determine that the first user device is a large-packet user device based on the large-packet user identifier, thereby sending the aforementioned first and second SRS resource allocation information to the first user device. Secondly, the switching message can also include a non-large-packet user identifier, and the target access network device can also determine that the first user device is not a large-packet user device based on the non-large-packet user identifier, thereby only sending the aforementioned first SRS resource allocation information to the first user device.

[0091] For easier understanding, see Figure 5 , Figure 5 This is a schematic diagram of another embodiment of the resource allocation method in the embodiment of the present application. As shown in the figure, user equipment 1 is within the cell range covered by access network equipment 1, so access network equipment 1 can determine whether user equipment 1 is a large-packet user equipment according to the service identification strategy. If the service attribute flag information is "1", it is a large-packet user equipment, and if the service attribute flag information is "0", it is a non-large-packet user equipment. Secondly, user equipment 2 is moving from the cell range covered by access network equipment 2 to the cell range covered by access network equipment 1. For user equipment 2, access network equipment 2 is the source access network equipment, and access network equipment 1 is the target access network equipment. Once it moves to the illustrated position, access network equipment 2 can send switching information to access network equipment 1, and access network equipment 1 can determine whether user equipment 2 is a large-packet user equipment according to the service attribute flag information carried in the switching information. If the service attribute flag information is "1", it is a large-packet user equipment, and if the service attribute flag information is "0", it is a non-large-packet user equipment. Therefore, the access network device can indicate whether the first user device is a large-packet user device based on the service attribute flag information in the switching message, and can also be promptly determined as a large-packet user device during the movement of the first user device, thereby sending semi-static SRS resources or non-periodic SRS resources in a timely manner, thereby improving the efficiency of resource allocation and thus improving the feasibility of the present application.

[0092] It should be understood that due to the limited number of semi-static SRS resources that can be allocated, the access network equipment allocates a set of semi-static SRS resources to one user equipment, and only one user equipment can be activated at the same time for a set of semi-static SRS resources, and the semi-static SRS resources cannot be activated and used by other user equipment until they are deactivated and released. Therefore, when multiple user equipment are allocated the same set of semi-static SRS resources, if at least two user equipment have corresponding service requirements at the same time, only one user equipment can be activated successfully, and other users will have semi-static SRS resource conflicts with it, resulting in the failure of semi-static SRS resource activation. At present, RRC signaling reconfiguration can be used to reallocate other semi-static SRS resources to provide services for user equipment, but the RRC signaling reconfiguration overhead will increase, thereby reducing the efficiency of resource allocation.

[0093] It should be noted that, therefore, the aforementioned semi-static SRS resource conflict problem can be solved by adopting round-robin scheduling or supporting the user equipment to configure multiple sets of semi-static SRS resources. The two methods are described below respectively:

[0094] 1. Round Robin Scheduling:

[0095] First, the access network device may send second SRS resource allocation information to the second user equipment, the second user equipment is a large packet user equipment, and the access network device activates the second SRS resource for the first user equipment or the second user equipment at the same time.

[0096] Further, when the access network device activates the second SRS resource for the first user equipment, the access network device starts a timer. When the timer expires, the access network device deactivates the second SRS resource for the first user equipment and activates the second SRS resource for the second user equipment.

[0097] For easier understanding, see Fig. 6A as well as Figure 6B , Fig. 6A as well as Figure 6B All of them are schematic diagrams of the method embodiments of round-robin scheduling in the embodiments of the present application, such as Fig. 6AAs shown, UE 1, which is identified as a large-packet user equipment, is allocated to semi-static SRS resource 0, UE 2 is allocated to semi-static SRS resource 1, UE 3 is allocated to semi-static SRS resource 2, and UE N is allocated to semi-static SRS resource 0. That is to say, UE 1 and UE N are allocated to the same semi-static SRS resource 0. First, the access network device can determine the service requirements of UE1 and UE N by whether there is an uplink scheduling request message. If UE 1 and UE N both have service requirements, but UE N preferentially sends an uplink scheduling request to the access network device, the access network device will activate the semi-static SRS resource 0 for UE N. When UE 1 then sends an uplink scheduling request to the access network device, a conflict will occur for the semi-static SRS resource 0.

[0098] Further, after a resource conflict occurs, see Figure 6B ,like Figure 6B As shown, the access network device can activate the semi-static SRS resource 0 of UE N through MACCE, and start the timer of the access network device. The timer duration can be 1s. During the timer operation, UE N continues to occupy the semi-static SRS resource 0. When the timer duration reaches 1s, it is necessary to first determine whether UE 1 currently has service requirements. If UE 1 currently has service requirements, the access network device can deactivate the semi-static SRS resource 0 of UE N through MAC CE, and activate the semi-static SRS resource 0 of UE 1 through MAC CE, and then continue to start the timer of the access network device. The timer duration can be 1s. When the timer duration reaches 1s, continue to repeat the above similar steps until UE 1 and UE N complete the service requirements. It should be understood that in actual applications, the timer can also be 2s, 4s and 8s, so the timer duration should not be understood as a limitation of this application.

[0099] In this embodiment, only one set of semi-static SRS resources is allocated to each user equipment. When a conflict occurs in the semi-static SRS resources, the semi-static SRS resources are activated in rotation among the user equipment through a timer, thereby ensuring that service demand is improved and the uplink and downlink BF performance of the user equipment is improved. Secondly, RRC signaling reconfiguration can be avoided, saving RRC signaling reconfiguration overhead.

[0100] 2. User equipment is configured with multiple sets of semi-static SRS resources:

[0101] When the second SRS resource information also indicates the third SRS resource, the period of the third SRS resource is the third period, and the third period is shorter than the first period, the access network device can first send the second SRS resource allocation information to the second user equipment, and the second user equipment is a large-packet user equipment. Secondly, when the access network device activates the second SRS resource for the first user equipment, the third SRS resource is activated for the second user equipment, or, when the access network device activates the third SRS resource for the first user equipment, the second SRS resource is activated for the second user equipment.

[0102] For easier understanding, see Figure 7 , Figure 7 This is a schematic diagram of an embodiment of a method for configuring multiple sets of resources in an embodiment of the present application. As shown in the figure, UE 1 to UE3, which are all identified as large-packet user equipment, can support allocation of multiple sets of short-period semi-static SRS resources. First, the access network device can determine the service needs of UE 1 to UE3 by whether there is an uplink scheduling request message. If UE 1 to UE3 all have service needs, but UE 3 has activated semi-static SRS resource 3 by sending an uplink scheduling request to the access network device, and UE 1 preferentially sends an uplink scheduling request to the access network device, the access network device activates semi-static SRS resource 1 for UE 1, and then when UE 2 sends an uplink scheduling request to the access network device, if the access network device activates semi-static SRS resource 1 for UE 2, a conflict will occur with the semi-static SRS resource 1 activated by UE 1. At this time, the access network device can activate other semi-static SRS resources for UE 2. For example, if the semi-static SRS resource 2 is in an idle and unactivated state, the access network device can activate the semi-static SRS resource 2 to UE 2 through MAC CE. Therefore, the activated semi-static SRS resources can be activated by the access network device and used by the user equipment in conflict, thereby reducing RRC signaling reconfiguration and saving RRC signaling overhead.

[0103] It should be understood that in actual applications, if multiple sets of semi-static SRS resources are configured for user equipment in the same cell, and the number of user equipment in the same cell is large, the number of allocable semi-static SRS resources is limited, and the limited semi-static SRS resources may be fully occupied. At this time, the access network equipment can adopt the aforementioned round-robin scheduling method for the semi-static SRS resources.

[0104] In combination with the above introduction, the resource allocation method used in the embodiment of the present application will be described in detail below with the first user equipment as the execution subject, please refer to Figure 8 , Figure 8 A schematic diagram of an embodiment of a method for resource allocation in an embodiment of the present application.

[0105] 201. A first user equipment receives first SRS resource allocation information from an access network device, where the first SRS resource allocation information indicates a first SRS resource, wherein a period of the first SRS resource is a first period;

[0106] In this embodiment, the first user equipment receives first SRS resource allocation information from the access network equipment. The first SRS resource allocation information may indicate a first SRS resource, and a period of the first SRS resource is a first period.

[0107] Specifically, the first SRS resource may be a periodic SRS resource. The first user equipment may receive the periodic SRS resource from the access network equipment via RRC signaling. After the first user equipment is configured with the periodic SRS resource, the resource has been activated and does not require other signaling triggering. Furthermore, the first user equipment may also periodically receive the periodic SRS resource. The first period corresponding to the periodic SRS resource configured with the first user equipment in different cells is also different. It should be understood that in actual applications, the first period may be but is not limited to 5ms, 10ms, 20ms, 40ms, 320ms or 640ms.

[0108] 202. The first user equipment receives second SRS resource allocation information from the access network equipment, where the second SRS resource allocation information indicates a second SRS resource, where the period of the second SRS resource is a second period, which is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, where the first user equipment is a large-packet user equipment.

[0109] In this embodiment, when the first user equipment is a large packet user equipment, the first user equipment may also receive second SRS resource allocation information from the access network device, and the second SRS resource allocation information may indicate a second SRS resource. When the second SRS resource is a periodic SRS resource, the period of the second SRS resource may be a second period, and the second period is shorter than the first period. Secondly, the second SRS resource may also be a non-periodic SRS resource.

[0110] In an embodiment of the present application, when the number of users in a cell is large, the first user device can receive periodic SRS resources from the access network device. Further, when the first user device is a large-packet user device, the first user device can also receive at least one of semi-static SRS resources or non-periodic SRS resources from the access network device, thereby ensuring that large-packet user devices are allocated resources first, thereby ensuring that the user devices can be allocated SRS resources, thereby improving the uplink and downlink BF performance of the user devices, and improving the uplink and downlink channel measurement accuracy, thereby improving the uplink and downlink transmission performance, for example, reducing the bit error rate of transmitted data and improving cell throughput.

[0111] Optionally, the large-packet user equipment is a user equipment whose average service data volume within a time range is greater than or equal to a target threshold. It should be understood that in practical applications, the large-packet user equipment can also be a service data flow with a maximum value or a minimum value within a time range, or a comparison between a value obtained by calculation and a target threshold value for the service data volume within a time range. The present application uses the average service data volume to determine the large-packet user equipment, which should not be understood as a limitation of the present application.

Optionally, with the development of wireless communication technology, a transceiver may be integrated into the communication device 900, for example, the communication unit 902 may be integrated with a Figure 2B A transceiver 212 is shown.

[0122] When the communication device 900 is a terminal or a chip in a terminal, the processing unit 901 can complete the method executed by the terminal in the above embodiment.

[0123] In a possible design, the processing unit 901 may include instructions, and the instructions may be executed on the processor, so that the communication device 900 executes the terminal method in the foregoing embodiment.

Optionally, data can also be stored in the storage unit 903. Optionally, the processing unit 901 can also store instructions and / or data.

[0125] For example, the communication unit 902 can receive first SRS resource allocation information from an access network device, the first SRS resource allocation information indicating a first SRS resource, wherein the period of the first SRS resource is a first period; the communication unit 902 can receive second SRS resource allocation information from an access network device, the second SRS resource allocation information indicating a second SRS resource, wherein the period of the second SRS resource is a second period, the second period is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, wherein the first user device is a large-packet user device, and the storage unit 902 can store the first SRS resource allocation information and the second SRS resource allocation information.

[0126] For the rest, reference may be made to the method of the terminal in the above embodiment, which will not be described in detail here.

[0127] The communication device 900 may be an access network device in an embodiment of the present application. Figure 2A Optionally, the communication unit 902 of the apparatus 900 may include an antenna and a transceiver of an access network device, for example Figure 2A The antenna 115 and the transceiver 113 in the embodiment. Optionally, the communication unit 902 may also include a network interface, such as Figure 2A The network interface 114 in.

[0128] The communication device 900 may be a chip in the access network device in the embodiment of the present application. The communication unit 902 may be an input or output interface, a pin or a circuit, etc. The storage unit 903 may be a register, a cache or a RAM, etc. The storage unit 903 may be integrated with the processing unit 901; the storage unit 903 may be a ROM or other types of static storage devices that can store static information and instructions, and the storage unit 903 may be independent of the processing unit 901. Optionally, with the development of wireless communication technology, a transceiver may be integrated into the communication device 900, for example, the communication unit 902 may be integrated with a Figure 2A The transceiver 113 is shown.

[0129] When the communication device 900 is an access network device or a chip in the access network device, the processing unit 901 can complete the method executed by the access network device in the above embodiment.

[0130] In one possible design, the processing unit 901 may include instructions, which can be executed on the processor so that the communication device 900 executes the method of the access network device in the above embodiment.

[0131] In another possible design, the storage unit 903 stores instructions, and the instructions can be executed on the processing unit 901, so that the communication device 900 executes the method of accessing the network device in the above embodiment. Optionally, data can also be stored in the storage unit 903. Optionally, instructions and / or data can also be stored in the processing unit 901.

[0132] For example, the communication unit 902 can send first SRS resource allocation information to the first user equipment, the first SRS resource allocation information indicates the first SRS resource, wherein the period of the first SRS resource is the first period; the communication unit 902 can send second SRS resource allocation information to the first user equipment, the second SRS resource allocation information indicates the second SRS resource, the period of the second SRS resource is the second period, the second period is shorter than the first period, or the second SRS resource is a non-periodic SRS resource, wherein the first user equipment is a large-packet user equipment.

[0133] For example, the processing unit 901 may also determine whether the first user equipment is a large-packet user equipment according to the amount of service data of the first user equipment within a time range.

[0134] For example, when the access network device is the target access network device, the communication unit 902 may also receive a switching message from the access network device or the source access network device, wherein the switching message includes information indicating that the first user equipment is a large packet user equipment.

[0135] For example, the communication unit 902 may send second SRS resource allocation information to the second user equipment, where the second user equipment is a large packet user equipment. The communication unit 902 may also activate the second SRS resource for the first user equipment or the second user equipment at the same time.

[0136] For example, when the processing unit 901 determines to activate the second SRS resource for the first user equipment, the communication unit 902 starts the timer. Further, the processing unit 901 can determine that after the timer expires, the communication unit 902 deactivates the second SRS resource for the first user equipment and activates the second SRS resource for the second user equipment.

[0137] For example, when the second SRS resource information also indicates a third SRS resource, the period of the third SRS resource is the third period, and the third period is shorter than the first period, the communication unit 902 can send second SRS resource allocation information to the second user equipment, and the second user equipment is a large-packet user equipment. Further, when the communication unit 902 activates the second SRS resource for the first user equipment, it activates the third SRS resource for the second user equipment, or, when the access network device activates the third SRS resource for the first user equipment, it activates the second SRS resource for the second user equipment.
