In the LTE (Long Term Evolution) system, the scheduling of the radio resources is performed by the evolved base station ENB (Evolved Node B). Therefore, when the user equipment UE (User Equipment) needs to perform data transmission, it first needs to send a scheduling request to the ENB. The uplink radio resource is obtained. After receiving the scheduling request of the UE, the ENB dynamically allocates the determined time-frequency resource to the UE according to the resource condition of the current system, and the dynamic allocation result is sent to the UE by using corresponding control signaling, that is, The uplink grant is sent; after receiving the uplink grant, the UE sends data according to the time-frequency resource indicated by the uplink grant.

It should be understood that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

It should be noted that, in the embodiment of the present invention, the base station may be an ENB, a Node B, an access point, or the like. Each base station can provide communication coverage for a particular geographic area. The term "Cell" may be the coverage area of a base station, and/or the coverage area served by a base station subsystem, depending on the context in which the term is used. The base station can provide communication coverage for macro cells, pico cells, femto cells, and/or other types of cells.

In this embodiment of the present invention, UEs may be distributed throughout the wireless network, and each UE may be static or mobile. The UE may be called a terminal, a mobile station (MS), a subscriber unit (Subscriber Unit), a station (Station), and the like. The UE can be a cellular phone, a personal digital assistant (PDA), a wireless modem (Modem), a wireless communication device, a handheld device (Handheld), a laptop computer, a cordless phone. ( Cordless Phone), Wireless Local Loop (WLL) station, etc. As shown in FIG. 2, an embodiment of the present invention provides a data interaction method, based on a base station, including the following steps:

511. The base station learns the processing capability of the UE.

512. The base station determines, according to processing capability of the UE, a data interaction period of the UE.

513. The base station sends configuration information of the data interaction period to the UE, so that the UE performs data interaction with the base station according to the data interaction period.

In the data interaction method provided by the embodiment of the present invention, in the data interaction between the UE and the base station, the base station dynamically assigns a data interaction period to the UE according to the processing capability of the UE, so that the UE uses the most suitable data interaction period according to its processing capability. The processing capability of the UE can be fully utilized, and processing delays such as codec decoding and scheduling transmission are reduced, thereby improving the data interaction speed of the system and significantly improving the performance of the communication system.

The data exchange between the UE and the base station refers to data exchange between the UE and the base station, including the process in which the base station or the UE transmits data to the other party, and the base station or the UE receives the data returned by the other party, for example, the base station or the UE sends the direction to the opposite party. The process of sending data to the other party in response.

The data exchange period of the UE refers to the time when the UE sends the uplink data to the air interface according to the uplink grant or the retransmission indication after receiving the uplink grant or retransmission indication of the base station, and also refers to the time after the UE receives the downlink data sent by the base station. The time at which the feedback message received by the data is sent to the air interface.

The processing capability of the UE reflects the processing performance of the UE when the UE performs data interaction with the base station. The data exchange period required by the UE with different processing capabilities is different when the data is exchanged with the base station. Therefore, the base station can process according to the UE. Ability to configure the appropriate data exchange period for the UE.

In an embodiment of the present invention, the processing capability of the UE may be characterized by a processing capability level recognized by both the base station and the UE, and each UE corresponds to a determined processing capability level. The processing capability level of the UE is determined according to various performance indicators of the UE, the model, or the UE, such as the memory capacity, the CPU frequency, and the like. For example, assume that the UE's processing capability is the strongest, the level is one, the second is the level two, and so on. The UE with the device model KS-52 is an upgrade product of the UE with the device model KS-51. The processing capability of the former is greatly improved compared with the latter. The processing capability level of the UE with the model KS-52 is level one, and the model number is The processing capability level of the UE of the KS-51 is level two. At this time, in step S11, the base station will know the processing capability level of the UE, and in step S12, determine the data interaction period of the UE according to the processing capability level of the UE.

Specifically, in step S11, the base station receives the processing capability level indication information sent by the UE, so as to obtain the processing capability level of the UE.

Optionally, the processing capability level indication information includes the processing capability level information of the UE, that is, directly indicating that the processing capability level of the UE is the first level, that is, the base station may directly input the processing capability level indication information, The processing capability level of the UE is known.

Optionally, the processing capability level indication information includes information corresponding to the processing capability level of the UE, such as an identity identifier of the UE, a product model of the UE, or at least one identifier processing capability of the UE. Performance indicators, such as memory capacity, CPU frequency, etc. Optionally, the UE's identity ID can indicate the UE's manufacturer. After receiving the information corresponding to the processing capability level of the U E, the base station determines the processing capability level of the UE according to the information and the correspondence between the information and the processing capability level of the UE.

Of course, the base station can also learn the processing capability level of the UE in other manners, which is not limited by the present invention.

Before receiving the processing capability level indication information of the UE, the base station may further send a processing capability level query instruction to the UE, so that the UE may report the processing capability level indication information according to the processing capability level query instruction. The processing capability query instruction may be sent to the UE in a separate instruction manner, or may be added to the existing capability query instruction to query the processing capability level of the UE. The present invention does not limit this.

Optionally, in another embodiment of the present invention, the processing capability of the UE may be dynamically changed. In this case, the processing capability of the UE may be characterized by an identifier parameter that identifies the processing capability of the UE. Specifically, the identifier of the UE processing capability may be at least one of a CPU usage of the UE, a load status of the UE, a physical location of the UE in the cell, and a current service type of the UE.

At this time, in step S11, the base station will learn the identification parameter of the processing capability of the flag UE, and in step S12, determine the data interaction period of the UE according to the identification parameter.

Obviously, the central processing unit (CPU) utilization of the UE affects the data interaction between the UE and the base station. If the CPU utilization of the UE is high, the UE is The processing power is poor. Specifically, in step S11, the base station can learn the CPU utilization rate of the UE by detecting the CPU utilization of the UE.

The signal-to-noise ratio of the cell center location data interaction signal is high, the data interaction speed is fast, the cell edge position signal is weak, and the signal interaction speed is slow. That is to say, the physical location of the UE in the cell also affects the processing capability of the UE. Optionally, in the embodiment of the present invention, the physical location of the UE in the cell includes: a cell center, a cell edge, a cell center, and a cell edge. In step S11, the base station can learn the physical location of the UE in the cell by detecting the physical location of the UE in the cell. Specifically, the base station detects the signal and interference plus noise ratio SINR (Signal to Interference plus Noise) corresponding to the UE. The Ratio test determines the physical location of the UE in the cell, for example, determining that the UE is located at the cell edge.

The load status of the cell also affects the data interaction between the UE and the base station. If the number of UEs loaded by the cell is large, the data traffic of a single UE will be limited, and the processing time of the average base station to each UE will be relatively reduced. Therefore, in order to ensure the communication quality of the base station and the UE, the base station can optimize the data interaction period of the UE according to the load status of the cell where the UE is located, and configure an appropriate data interaction period for the UE. Specifically, in step S11, the base station can learn the load status of the cell by detecting the load status of the cell.

For different service types of the UE, the real-time requirements of the data exchange between the base station and the UE are different. Therefore, the service type of the UE is different, and the requirements of the data interaction period are different. The base station can configure different data interaction periods for the UE according to different service types. Specifically, in step S11, the base station can learn the service type of the UE by detecting the service type of the UE. In another embodiment of the present invention, the processing capability of the UE may be jointly characterized by the processing capability level of the UE and the identification parameter of the foregoing marking UE processing capability. In this case, the base station needs to know the processing capability level of the UE in addition to the UE. The identification parameter of the processing capability of the marking UE, that is, the data interaction method of the embodiment of the present invention, further includes: the base station learning the CPU utilization of the UE, the load status of the cell where the UE is located, and the UE is in the The physical location in the cell, any one of the current service types of the UE. In step S12, the base station determines the data interaction period of the UE according to the learned processing capability level of the UE and the identification parameter. After learning the processing capability of the UE, in step S12, the base station determines the data interaction period of the UE according to the processing capability of the learned UE. In the base station, the correspondence between the processing capability of the UE and the data interaction period is preset, and the base station selects the data interaction period corresponding to the processing capability for the UE according to the learned processing capability.

For example, the base station is pre-set with a correspondence between the processing capability level of the UE and the data interaction period. After the base station learns the processing capability level of the UE, the base station can determine the location by querying the corresponding processing item of the processing capability level and the data interaction period. The data interaction period of the UE. For example, if the processing capability level of the UE is level one, it indicates that the processing capability of the UE is the strongest, and the data interaction period supported by the UE is 1 ms. If the processing capability level is level four, it indicates that the processing capability of the UE is weak. The data interaction period supported by the UE is 4 ms.

It can be understood that the data interaction period corresponding to the processing capability level of the UE is the minimum data interaction period supported by the UE. When the data interaction period supported by the UE is 1 ms, the UE can support all data interaction periods greater than or equal to 1 ms. Data interaction.

When the processing capability of the UE is characterized by the identifier of the processing capability of the UE, if the CPU usage of the UE is high, the processing capability of the UE is poor, and the base station can configure a large data interaction period for the UE. Reduce the load on the CPU of the UE.

If the number of UEs loaded by the cell is large, the data traffic of a single UE will be limited, and the processing time of the average base station to each UE will be relatively reduced. Therefore, in order to ensure the communication quality between the base station and the UE, the base station can configure a smaller data interaction period for the UE. In this way, the UE in the cell performs data interaction in a single small-flow, high-frequency data interaction manner, that is, the duration of each data interaction is appropriately reduced, but the number of data interactions per unit time is increased, so that each UE can be timely Data interaction with the base station improves the data exchange performance of the system.

If the UE is at the cell edge, in order to improve the communication efficiency of the UE, the base station may configure a shorter data interaction period for the UE, for example, 2 ms, so that the cell edge user communication speed is improved, and the handover user signaling interaction delay is effective. Reduced, which improves the performance of the system.

For different service types of the UE, the real-time requirements of the data exchange between the base station and the UE are different. Therefore, the base station can configure different data interaction periods for the UE according to different types of services. For example, a 1 ms data interaction period is configured for a telephony service with a higher real-time requirement, and a 5 ms data interaction period is configured for an Internet service with a low real-time requirement. In an embodiment of the present invention, in step S12, the base station first determines, according to the processing capability level of the UE, that the processing capability of the UE is jointly characterized by the processing capability level and the identifier of the UE processing capability. The data exchange period of the UE, that is, the minimum data interaction period supported by the UE, and then, according to the CPU utilization of the UE, the load status of the cell in which the UE is located, and the physical location of the UE in the cell in which the UE is located And the one of the current service types of the UE adjusts the data interaction period of the UE. In this step, in step S13, the base station sends the adjusted configuration information of the data interaction period of the UE to the UE. For example, the processing capability level of the UE is level 2, the minimum data interaction period that can be supported is 2 ms, and the CPU utilization of the UE is higher, greater than 90%, and the base station will exchange the minimum data according to the CPU utilization of the UE. The period is adjusted to configure a larger data interaction period for the UE, such as 4ms, to reduce the load on the CPU.

In step S13, optionally, the base station may send configuration information of the data interaction period to the UE by using layer 3 (L3) signaling, where the configuration information of the data interaction period indicates the data interaction configured by the base station for the UE in step S12. The period is such that the UE performs data interaction with the base station according to the data interaction period. Optionally, the base station may also notify the UE of the data interaction period configured for the UE by updating the system message. Such a notification method for updating the system message is preferably applied to a case where there are many UEs with a cell load.

Further, for the base station, the base station receiving the data sent by the UE will feedback the data reception, and after receiving the data sent by the UE from the base station, the base station will wait for a certain time to provide feedback on the data reception, and the base station waits for the time. The length of the data may be the same as the data exchange period of the UE, or may be different. The present invention does not limit this. Preferably, after the base station receives the data uploaded by the UE according to the data exchange period configured by the base station, the base station may perform the feedback of the data reception according to the data exchange period of the UE, thereby further improving the data interaction speed and reducing the data. The processing delay of the communication system improves the performance of the system. For example, the data exchange period configured by the base station for the UE is 3 ms. After receiving the data sent by the UE, the base station will feed back the data reception after 3 ms. For example, if the data is successfully received, the base station performs the data interaction. The receiving data success message is fed back during the period. If the receiving data fails, the UE needs to retransmit the data. The base station feeds back Hybrid Automatic Repeat Request (HARQ) information, and requests the UE to retransmit the data.

Specifically, taking the UE-second uplink ping packet service as an example, when the UE receives the data to be sent, the UE immediately sends a signal on the air interface to apply for the uplink authorization, and the base station understands the UE. After the processing capability, the data exchange period configuration information and the uplink authorization are sent to the UE, and the UE performs data interaction with the base station according to the uplink authorization and the data interaction period configured by the base station, so as to adjust the delay time by configuring the data interaction period, The purpose of improving the data exchange speed of the UE is, so the data interaction efficiency and performance of the system are greatly improved.

Correspondingly, as shown in FIG. 3, the embodiment of the present invention provides a data interaction method, based on the UE, including the following steps:

S21. The UE receives configuration information of a data interaction period of the UE from the base station.

The data exchange period is determined by the base station according to the processing capability of the UE.

The processing capability of the UE may be the same or different. The base station configures an appropriate data interaction period for the UE according to the processing capability of the UE, which can effectively improve the data interaction speed of the system and improve system performance.

The information may include the identity ID of the UE, the product model of the UE, or at least one performance indicator of the UE's processing capability, such as memory capacity, CPU frequency, and the like. After receiving the information corresponding to the processing capability level of the UE, the base station determines the processing capability level of the UE according to the information and the correspondence between the information and the processing capability level of the UE.

The UE sends an identifier parameter indicating the processing capability of the UE to the base station, so that the base station learns the processing capability of the UE. The identifier parameter includes at least one of a CPU usage of the UE, a load status of the cell, a physical location of the UE in the cell, and a current service type of the UE.
