Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The data transmission method provided by the application can be applied to an application environment shown in fig. 1, and the base station 100 is in communication connection with the user equipment 200. The user device 200 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The base station may be, but not limited to, a macro base station, a micro base station, a small base station, or other base station devices, and may be a base station (Base Transceiver Station, BTS) in global mobile communications (Global System of Mobile communication, abbreviated GSM) or code division multiple access (Code Division Multiple Access, abbreviated CDMA), a base station (NodeB, abbreviated NB) in wideband code division multiple access (Wideband Code Division Multiple Access, abbreviated WCDMA), an evolved base station (Evolutional Node B, abbreviated eNB or eNodeB) in LTE, or a relay station or an access point, or a base station in future 5G network, a customer premise equipment (Customer Premise Equipment, abbreviated CPE), a narrowband internet of things base station, or the like.
In one embodiment, as shown in fig. 2, a data transmission method is provided, which is illustrated by taking an example that the method is applied to the base station in fig. 1, and includes:
s101, acquiring a time delay requirement of User Equipment (UE) which is accessed currently, and determining a target user group corresponding to the UE according to the time delay requirement; the delay requirements corresponding to UEs in different user groups are different.
In the NR system, the corresponding time delay requirements of the UE in different service scenes are different, for example, the base station and the UE need to realize low-time delay communication in a URLLC scene. The above-mentioned delay requirement may be an end-to-end delay of the user plane, or may be a delay of the resource request, and the type of the delay requirement is not limited herein. The user plane end-to-end delay may be one-way delay that data sent by the UE is sent to the base station, and then the base station processes the data and sends the processed data to the core network through the backhaul network; the above-mentioned resource request delay may be a duration from when the UE sends an uplink resource request to the base station to when the UE receives an uplink resource configured by the base station. The uplink resource may be a physical uplink control channel (Physical Uplink Control Channel, abbreviated PUCCH) resource or an uplink shared physical channel (Physical Uplink Share CHannel, abbreviated PUSCH), which is not limited herein.
The time delay requirement can be a time delay range corresponding to the UE, or can be the highest time delay corresponding to the UE; the form of the latency requirement is not limited herein.
Specifically, the UE may report a delay requirement to the base station when initially accessing the base station, so that the base station may obtain the delay requirement of the UE according to information reported by the UE; or the base station can acquire the service type supported by the UE and then determine the time delay requirement of the UE according to the service type; the method for acquiring the delay requirement is not limited herein.
The base station can group the accessed UE, divide the UE with similar time delay requirement into the same user group, and determine the corresponding target user group of the UE. Specifically, the base station may determine the target user group of the UE according to matching between the delay requirement of the UE and a preset grouping condition, or may determine the target user group of the UE according to the delay requirement of the UE and the service type supported by the UE, which is not limited herein.
The base station may divide the accessed UEs into 2 user groups or may divide the accessed UEs into 3 or more user groups. Optionally, the base station may divide the multiple UEs into 3 user groups, which are respectively an ultra-low latency user group, a low latency user group and a non-low latency user group, and the target user group corresponding to the UE may be one of the ultra-low latency user group, the low latency user group and the non-low latency user group.
S102, determining the public uplink resources corresponding to the target user group as the public uplink resources in the group of the UE.
The base station may configure a set of common uplink resources for each user group. The base station may configure the common uplink resources for the ultra-low latency user group to be greater than the common uplink resources configured for the non-low latency user group. After determining the target user group of the UE, the base station may determine, according to the corresponding relationship between the preset user group and the common uplink resource, the common uplink resource corresponding to the target user group, and determine the common uplink resource as the intra-group common uplink resource of the UE.
S103, sending indication information of pre-allocated uplink resources to the UE; the pre-allocated uplink resources comprise dedicated uplink resources of the UE and intra-group public uplink resources; the indication information is used for indicating the UE to determine the target uplink resource based on the pre-allocated uplink resource and sending uplink data through the target uplink resource.
Based on the above steps, the base station may further configure an exclusive uplink resource for the UE, and determine the exclusive uplink resource and the intra-group public uplink resource of the UE as a pre-allocated uplink resource of the UE. Further, the base station may send the indication information of pre-allocating the uplink resource to the UE. The indication information may include configuration information of pre-allocated uplink resources, and may further include a determining policy for determining a target uplink resource in the pre-allocated uplink resources by the UE.
After receiving the indication information, the UE can determine pre-allocated uplink resources configured by the base station, determine target uplink resources in the pre-allocated uplink resources according to the indication information, and then send uplink data through the target uplink resources. The base station may instruct the UE to randomly select the target uplink resource from the dedicated uplink resource and the intra-group common uplink resource configured for the UE, or instruct the UE to determine the target uplink resource according to the data amount of the uplink data. The target uplink resources may be all located in the dedicated uplink resources of the UE, may be all located in the intra-group common uplink resources, or may be both located in the dedicated uplink resources of the UE and the intra-group common uplink resources, which is not limited herein.
Optionally, the indication information is specifically configured to instruct the UE to determine the target uplink resource in the common uplink resource in the group when the dedicated uplink resource of the UE cannot meet the uplink resource requirement. After receiving the indication information, the UE can determine whether the dedicated uplink resource of the UE meets the uplink resource requirement according to the size of the uplink data to be sent. If the size of the uplink data to be sent is smaller than or equal to the size of the dedicated uplink resource of the UE, determining that the dedicated uplink resource of the UE can meet the uplink resource requirement, and determining the target uplink resource in the dedicated uplink resource by the UE. If the size of the uplink data to be sent is larger than the size of the dedicated uplink resource, the dedicated uplink resource of the UE cannot meet the uplink resource requirement, and after the UE transmits part of the uplink data in the dedicated uplink resource, the UE determines a target uplink resource in the common resource in the group to transmit the remaining uplink data; and after the UE finishes uplink data transmission by using the intra-group public uplink resources, timely releasing the intra-group public uplink resources.
According to the data transmission method, the base station acquires the time delay requirement of the User Equipment (UE) which is accessed currently, and determines the target user group corresponding to the UE according to the time delay requirement; then, the public uplink resources corresponding to the target user group are determined to be the public uplink resources in the group of the UE; and sending indication information of pre-allocation uplink resources to the UE; wherein, the time delay requirements corresponding to the UE in different user groups are different; the pre-allocated uplink resources comprise dedicated uplink resources of the UE and intra-group public uplink resources; the indication information is used for indicating the UE to determine the target uplink resource based on the pre-allocated uplink resource and sending uplink data through the target uplink resource. The base station determines the target user group of the UE according to the time delay requirement of the UE, so that the intra-group public uplink resource corresponding to the UE can be determined according to the target user group, the UE with different time delay requirements can have the corresponding intra-group public uplink resource, and the intra-group public uplink resource can meet the resource requirement of the UE more; further, the pre-allocated uplink resources indicated by the base station to the UE comprise the dedicated uplink resources of the UE and the intra-group public uplink resources of the UE, so that the pre-allocated uplink resources obtained by the UE are richer, failure of the UE in sending uplink data under the condition of insufficient dedicated uplink resources can be avoided, and the transmission reliability of the uplink data is improved; in addition, because the base station pre-allocates the uplink resources indicated by the UE, the UE does not need to initiate a resource request to the base station and wait for the base station to allocate the uplink resources when sending the uplink data, but can directly upload the uplink data on the pre-allocated uplink resources, thereby reducing the transmission delay of the data.
Fig. 3 is a flow chart of a data transmission method in another embodiment, which relates to an implementation manner of determining a target user group of a UE by a base station, and based on the above embodiment, as shown in fig. 3, the step S101 includes:
s201, comparing the time delay requirement of the UE with a preset time delay threshold value, and determining a threshold value interval corresponding to the time delay requirement.
When determining the target user group of the UE, the base station may compare the delay value in the delay requirement of the UE with a preset delay threshold value, and determine a threshold interval corresponding to the delay requirement. For example, the delay thresholds may be 5ms and 10ms, and the threshold intervals may include three threshold intervals of less than or equal to 5ms, greater than 5ms and less than 10ms, and greater than 10 ms. The base station may determine a threshold interval matching the delay requirement from the plurality of threshold intervals according to the delay requirement of the UE.
S202, determining the user group corresponding to the threshold interval as a target user group of the UE.
Further, each threshold interval corresponds to a user group, and the base station may determine the user group associated with the threshold interval corresponding to the UE as the target user group of the UE.
According to the data transmission method, the base station can rapidly determine the target user group of the UE according to the preset time delay threshold, so that pre-allocated uplink resources can be rapidly configured for the UE, and the efficiency of resource configuration is further improved.
In an embodiment, when the base station determines the intra-group common uplink resource of the UE on the basis of the above embodiment, the base station may also determine the common uplink resource corresponding to the other user groups except the target user group as the inter-group common uplink resource of the UE. For example, the target user group of the UE is an ultra-low latency user group, and the base station may use the common uplink resources configured for the low latency user group and the non-low latency user group as the inter-group common uplink resources of the UE, and use the common uplink resources of the above components as the pre-allocated uplink resources of the UE.
Correspondingly, the indication information sent to the UE by the base station is also used for indicating that the UE determines the target uplink resource in the inter-group common uplink resource under the condition that the intra-group common uplink resource cannot meet the uplink resource requirement. The UE may determine the target uplink resource in the inter-group common uplink resource, so that uplink data that cannot be transmitted through the intra-group common uplink resource may be transmitted through the target uplink resource in the inter-group common uplink resource. Further, after completing uplink data transmission, the UE may release the intra-group common uplink resource and the inter-group common uplink resource at the same time, so that the above resources may be invoked by other UEs.
According to the data transmission method, the base station configures the inter-group public uplink resources for the UE, so that the pre-allocated uplink resources obtained by the UE are richer, and when the intra-group public uplink resources and the dedicated uplink resources of the UE cannot meet the requirements, the UE can acquire the available target uplink resources from the inter-group public resources, so that failure of the UE in sending uplink data caused by insufficient dedicated uplink resources of the UE can be avoided, and the transmission reliability of the uplink data is improved.
In one embodiment, on the basis of the foregoing embodiment, UEs in different user groups may correspond to different transmission priorities; wherein, the smaller the delay value in the delay requirement, the higher the corresponding transmission priority. For example, the transmission priority of the UE in the ultra-low latency user group is higher than the transmission priority of the UE in the low latency user group; the transmission priority of the UE in the low latency user group is higher than the transmission priority of the UE in the non-low latency user group.
The pre-allocated uplink resources also comprise exclusive uplink resources of other UE, and the transmission priority of other UE is lower than that of the UE; the indication information is also used for indicating that the UE determines the target uplink resource in the exclusive uplink resources of other UEs under the condition that the inter-group public uplink resources can not meet the uplink resource requirement. The base station can simultaneously indicate the exclusive uplink resources of other UEs to the UE, so that the UE can preempt the exclusive uplink resources of the low-priority user when the base station cannot obtain enough target uplink resources in the exclusive uplink resources, the intra-group public uplink resources and the inter-group public uplink resources configured for the base station.
According to the data transmission method, the base station configures the exclusive uplink resources of other UE for the UE, so that under the condition that the uplink resources configured by the base station are insufficient, the uplink resource requirements of the UE with higher transmission priority can be preferentially met through the time-line method.
The data transmission delay between the base station and the UE is related to the time length of the UE for acquiring the uplink resource, the data processing time length of the data receiving end and the time unit of data transmission.
For a time unit of data transmission, taking the time unit as a subframe (for example, 0.5 ms) as an example, the base station transmits the data volume of one subframe to the UE each time, when the UE needs low-delay transmission, the data transmission with the subframe as the unit cannot meet the delay requirement below the millisecond level of the UE. In an embodiment, based on the above embodiment, the base station and the UE perform data transmission in units of a preset number of symbols; the duration of the preset number of symbols is less than the duration of half a subframe. For example, a 2 symbol minislot may be used as the minimum transmission unit between the base station and the UE. By adopting the method, the time granularity of data transmission between the base station and the UE is smaller, and the transmission delay of the data is reduced.
Further, after determining the preset number of symbols corresponding to the minimum transmission unit, the base station may also reduce the duration of each symbol by adjusting the subcarrier spacing. For example, the duration of a single symbol at a subcarrier spacing of 120KHz is less than the duration of a single symbol at a subcarrier spacing of 30 KHz. By increasing the subcarrier spacing, the base station can further reduce the duration of the minimum transmission unit, so that the time granularity of data transmission between the base station and the UE is smaller, and the transmission delay of the data is further reduced.
By adopting the data transmission method, the base station can integrally reduce the transmission delay of all the UE accessed to the base station by adjusting the duration of the minimum transmission unit, thereby integrally improving the data transmission performance of the base station.
In an embodiment, based on the above embodiment, the base station may monitor the data processing duration, and timely screen the transmission data with abnormal data processing duration.
Specifically, for downlink data, after the base station receives a data stream of the downlink data from the core network, the base station may map the downlink data onto a bearer of a packet data convergence (Packet Data Convergence Protocol, abbreviated as PDCP) layer through a service data adaptation (Service Data Adaptation Protocol, abbreviated as SDAP) layer, and then header compress and encrypt the downlink data through the PDCP layer; the downlink data processed by the PDCP layer is submitted to a radio link control layer (Radio Link Control, RLC) layer for slicing, and then sent to the UE through a medium access control (Media Access Control, MAC) layer and a physical layer. For uplink data, after receiving the uplink data sent by the UE, the base station processes the uplink data in a flow opposite to the flow of processing the downlink data.
The base station can mark the time stamp on the processed data through each data processing module in the base station, so that the data processing time length of each data processing module can be counted according to each time stamp to monitor whether the data processing time length meets the requirement.
It should be understood that, although the steps in the flowcharts of fig. 2-3 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2-3 may include multiple steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the steps or stages are performed necessarily performed in sequence, but may be performed alternately or alternately with at least a portion of the steps or stages in other steps or other steps.
In one embodiment, as shown in fig. 4, there is provided a data transmission apparatus including:
the acquisition module 10 is configured to acquire a delay requirement of a currently accessed UE, and determine a target user group corresponding to the UE according to the delay requirement; the time delay requirements corresponding to the UE in different user groups are different;
