In the communication system, the method of dynamic scheduling is used to transmit data, and the base station will send a dynamic scheduling resource configuration message to the user equipment through the control channel at each data transmission time interval/transmission period (Transmit Time Interval, TTI), so that the base station In each TTI, dynamic scheduling resources are configured for the user equipment, so that the user equipment uses the dynamic scheduling resources of the uplink data channel to send data.

Semi-persistent scheduling is defined in Long Term Evolution (LTE). The base station only needs to send a configuration message to the user equipment through the control channel once. The configuration message contains information about semi-persistent scheduling resources, such as resource usage time interval, The information such as the data size carried by the resources completes the configuration of the semi-static resources of the user equipment by the base station; the user equipment can use the semi-static scheduling resources to send data in the subsequent uplink data channel, which saves the resources of the control channel; When statically scheduled resources can carry some low-flow services with fixed intervals and fixed-size data packets, such as Voice over Internet Protocol (VoIP) services, the quality of data transmission will be improved.

However, in the LTE system, when the user equipment sends data in the uplink data channel, it sends data according to the priority order of the data, so the following situation occurs: services other than VoIP with higher priority occupy the semi-static Scheduling resources, so that VoIP services with lower priority are not carried and sent with semi-static scheduling resources, resulting in delay jitter of VoIP services, resulting in degradation of voice quality for transmission.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a method for sending user equipment data, the flowchart of which is shown in Figure 1, including:

101. Acquire bearer information of semi-persistent scheduling resources, where the bearer information does not include service information other than semi-persistent scheduling services;

Semi-persistent scheduling services refer to some low-traffic services that need to send fixed-size data packets at fixed intervals, such as VoIP services. When these services are carried and sent through semi-persistent scheduling resources, the quality of data transmission will improve. Bearer information refers to the information of service data that can be carried by semi-persistent scheduling resources. The bearer information does not include other service information other than semi-persistent scheduling services, but can include information related to the bearer of semi-persistent scheduling resources, such as VoIP and other services. Information about multiple services, resource usage intervals, and data size carried by resources. That is to say, the semi-persistent scheduling resource cannot carry other service data other than the semi-persistent scheduling service.

The transmission of data by the user equipment through the uplink data channel is controlled by the configuration of the network side. The base station will send the configuration message of the semi-persistent scheduling resource to the user equipment through the control channel, and the configuration message contains the bearer information of the semi-persistent scheduling resource; the user equipment Resource configuration will be performed locally according to the received configuration message. This process is the activation process of semi-statically scheduled resources.

102. According to the bearer information obtained in step 101, when it is determined that the current TTI has semi-persistent scheduling resources, send the semi-persistent scheduling service data to be sent through the semi-persistent scheduling resources of the uplink data channel according to the bearer information.

It can be understood that when the semi-persistent scheduling resources are activated, there will not be semi-persistent scheduling resources in every TTI, but semi-persistent scheduling resources will only be available at fixed intervals. The message is configured in the local user equipment, that is, the resource usage interval in the bearer information. When it is determined according to the resource usage interval in the bearer information that the current TTI has semi-persistent scheduling resources, and there are currently multiple service data to be sent through the uplink data channel, the user equipment will not send data according to the priority order of the data, but The data corresponding to the semi-persistent scheduling service included in the bearer information, that is, the semi-persistent scheduling service data to be sent, is carried by the semi-persistent scheduling resource of the TTI and then sent.

It can be seen that in the embodiment of the present invention, it is determined according to the bearer information that the current TTI has semi-persistent scheduling resources, and according to the acquired bearer information of the semi-persistent scheduling resources, the semi-persistent scheduling service data to be sent is passed through the semi-persistent scheduling resources of the uplink data channel to send. Since the bearer information in this embodiment does not include other service information other than the semi-persistent scheduling service, the data sent when there are semi-persistent scheduling resources must be the semi-persistent scheduling service data in the bearer information, and there will be no other services Data occupies semi-persistent scheduling resources, thereby ensuring the transmission quality of semi-persistent scheduling service data.

In a specific embodiment, when performing the above step 101, it can be realized through the following steps: the user equipment receives the configuration message of the semi-persistent scheduling resource sent by the base station, and the configuration message includes the Information about other business data that does not use semi-persistent scheduling resources to carry. specifically:

The base station can send a radio resource control protocol (Radio Resource Control, RRC) configuration message, and include semi-persistent scheduling service information in the bearer information element of the semi-persistent scheduling resource of the RRC message, so that it can indicate that the semi-persistent scheduling resource can only bear It contains the data of the semi-persistent scheduling service. The base station can also send a MAC layer message or an RRC layer message through the Media Access Control (MAC) layer or the RRC layer respectively, and the MAC layer or RRC layer message contains semi-persistent scheduling service information, and configures the bearer message to the local user equipment.

When performing the above step 101, it may also be implemented by the following steps: the user equipment searches for the bearer information of the semi-persistent scheduling resource configured by the local user equipment according to the configuration message sent by the base station during the activation of the semi-persistent scheduling resource.

Referring to the method of another specific embodiment shown in FIG. 2, this embodiment is similar to the embodiment shown in FIG. After the static scheduling resource is activated, branch step 102 can be executed, and branch steps 103 and 104 can also be executed:

103. When it is determined that the current TTI has no semi-persistent scheduling resources according to the bearer information obtained in step 101, determine whether the semi-persistent scheduling service data to be sent conforms to the preset first strategy, and if so, execute step 104; if not , then when sending the semi-persistent scheduling service data to be sent, it is necessary to wait until the TTI of the semi-persistent scheduling resource arrives before using the semi-persistent scheduling resource to carry the transmission;

104. The dynamic scheduling resource bearer may be used to send the semi-persistent scheduling service data to be sent.

The first strategy here may include but not limited to at least one of the following information: the total amount of semi-persistently scheduled service data to be sent exceeds the preset data volume range; the unit data size of the semi-persistently scheduled service data to be sent exceeds the preset data size range etc.

It can be understood that in each TTI, the base station will send a dynamic scheduling resource configuration message through the control channel to configure dynamic scheduling resources, and semi-persistent scheduling resources are not available in every TTI. If the resource usage interval in the bearer information is used to determine When there is no semi-static scheduling resource in the current TTI, there may be semi-static scheduling service data with higher priority to be sent, or other service rates exceed the configured priority rate (Prioritized Bit Rate, PBR) of dynamic scheduling resources, etc. , at this time, when sending semi-persistently scheduled service data, dynamic scheduling resources can be used to carry the transmission.

In order to avoid that when the TTI of the semi-persistently scheduled resource arrives, no semi-persistently scheduled service data is sent, resulting in the deactivation of the semi-persistently scheduled resource, in this embodiment, when the semi-persistently scheduled service data to be sent can meet the preset In the first strategy, dynamic scheduling resources are used, thereby avoiding processing processes such as reallocation and activation of semi-static scheduling resources after deactivation of semi-static scheduling resources, and saving network resources.

Semi-persistent scheduling service data can also be sent using dynamic scheduling resources when the following situations occur:

The current TTI has semi-persistently scheduled resources and dynamically scheduled resources; or,

When it is determined according to the bearer information that the current TTI has semi-persistent scheduling and dynamic scheduling resources, and it is determined that the semi-persistent scheduling service data to be sent conforms to the preset first policy. In the above two cases, the semi-persistent scheduling resource and the dynamic scheduling resource can be used simultaneously to carry and send the semi-persistent scheduling service data to be sent.

Situations in which the semi-persistent scheduling service data may be sent by using the dynamic scheduling resource bearer include but are not limited to the above listed situations.

Referring to FIG. 3 , in other specific embodiments, after the bearer information of the semi-persistent scheduling resource is obtained through step 101, that is, after the semi-persistent scheduling resource is activated, branching step 102 can be performed, and branching steps 105 and 106 can also be performed:

105. If the buffer area of the user equipment is empty, and according to the bearer information obtained in step 101, it is determined that the TTI of the semi-persistent scheduling resource has not arrived, determine that the semi-persistent scheduling service data to be sent conforms to the preset second policy, and send the scheduled Request resource scheduling to the base station; it can be understood that if the semi-persistently scheduled service data to be sent does not comply with the preset second policy, the user equipment will not send a scheduling request.

The second strategy here includes but is not limited to at least one of the following information: the total amount of semi-persistently scheduled service data to be sent exceeds the preset data volume range; the unit data size of the semi-persistently scheduled service data to be sent exceeds the preset data size range wait.

106. When receiving the resource configuration message sent by the base station, send the semi-persistent scheduling service data to be sent according to the resource configuration message.

It can be understood that when the current semi-persistent scheduling service data arrives, such as the arrival of VoIP packet data, if the buffer of the user equipment is empty, and the TTI of the semi-persistent scheduling resource is determined according to the resource usage interval in the bearer information. The device will send a scheduling request (Scheduling Request, SR); since the SR has only 1 bit (bit), the base station does not know what business the user equipment currently needs to send when receiving the SR, and will configure dynamic scheduling resources for the user equipment , so that there may be no semi-persistent scheduling service data to send when the TTI of the semi-persistent scheduling resource arrives.

In order to avoid deactivation of the semi-persistent scheduling resource due to no semi-persistent scheduling service data being sent when the TTI of the semi-persistent scheduling resource arrives, in this embodiment, as long as the semi-persistent scheduling service data to be sent can meet the preset In the second strategy, the SR is sent to the base station for resource scheduling, thereby avoiding the re-allocation and activation of the semi-persistent scheduling resources after the semi-persistent scheduling resources are deactivated, and saving network resources.

It should be noted that, the preset data amount range and/or preset data size range in the first strategy and the second strategy are thresholds configured by the base station to the local user equipment through the RRC layer or the MAC layer. Specifically, the RRC layer of the base station adds these thresholds to the RRC reconfiguration signaling and sends it to the RRC layer of the user equipment, and the RRC layer of the user equipment stores the thresholds therein after receiving the RRC reconfiguration signaling; or the base station's The MAC layer sends a MAC Control element (MAC Control element, MCE) to the MAC of the user equipment, and the MAC layer of the user equipment stores the threshold value therein after receiving it.
