Description
Technical field
The present invention relates to the uplink data transmission method in Radio Transmission Technology, more particularly to a kind of Internet of Things,
Base station and terminal.
Background technology
In recent years, explosive growth is presented in Internet of Things (IoT, Internet of Things) application, according to correlation
Mechanism predicts that the quantity to the year two thousand twenty machine type terminal (MTD, Machine-Type Device) will
More than thousand times of individual mobile terminal quantity are reached, Industry Control, intelligent meter data recording, disaster prison is mainly used in
The fields such as control.Mobile communications network has wide coverage, and the characteristics of reliability is high carries internet of things service
With natural advantage, therefore industry has been classified as Internet of Things application prevailing scenario and the drive of 5G mobile networks
Power.
For most Internet of Things application for, magnanimity connection, low cost, small data packets, low-power consumption,
Hypomobility or Immobility, it is up based on transmission be its key character, use with person to person (H2H,
Human-to-Human Internet of Things is carried centered on) communicating come the mobile communications network (2G/3G/4G) designed
Net application will face lot of challenges, current third generation partner program (3GPP, 3rd Generation
Partnership Project) carry out for arrowband Internet of Things (NB-IoT, Narrow Band IoT) and grind
Study carefully and standardization effort, emphasis is optimized and changed to the communication system based on H2H for different application scene
Make, to meet the specific demand of internet of things service.
Terminal initiates Stochastic accessing and sets up wireless heterogeneous networks (RRC, Radio Resource Control) even
Connect with after radio bearer, when needing to send upstream data, if the ascending resource of existing base station distribution, just
Transmitting uplink data can be started；If can not carry out the resource of uplink, need be by one
Row flow could complete the transmission of upstream data, the whole flow process that 3GPP is formulated as shown in figure 1, including：
1st, dispatch request (SR, Scheduling Request)：It is first when terminal (UE) needs to send data
First Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) is asked to base station (eNB)
Resource.Under normal circumstances, terminal base station during connection is set up is configured to send by RRC signaling
SR uplink control channel (PUCCH, Physical Uplink Control Channel) resource, UE
Dispatch request can be sent to by base station by PUCCH channels.In some cases, when UE is due to one section
Between no business and lose uplink synchronous or base station is configured without PUCCH resource, UE, which can pass through, to initiate
Stochastic accessing obtains uplink synchronous and asks uplink shared channel resources.
2nd, ascending resource assigns (UL Grant)：Base station is received after the SR of terminal transmission, and distribution is a small amount of
Ascending resource is to allow terminal reporting buffer status report (BSR, Buffer Status Report), and this is up
Resource assigns information and passes through downlink control channel (PDCCH, Physical Downlink Control
Channel) transmission.
3、BSR：Terminal is by sending BSR to the upper of network side offer terminal inner service with different priority levels
The size of row buffer data size, so as to base station rational management uplink shared resources.
4、UL-Grant：Base station is received after the BSR that terminal is reported, the BSR that is reported according to the terminal and
The comprehensive analysis such as base station existing resource decide whether the size to UE distribution resources and to terminal distribution resource
With the information such as modulation system.
In addition, in order to reduce control channel expense, for Voice over IP (VoIP, Voice over Internet
Protocol) this kind of data package size relatively fix, arrival time interval meet the real-time service of certain rule,
Long Term Evolution (LTE, Long Term Evolution) introduces a kind of new scheduling mode-semi-persistent scheduling
Technology (SPS, Semi-Persistent Scheduling).SPS refers to during LTE scheduled transmission,
ENB indicates the current schedule informations of UE in initial schedule by PDCCH, and UE identifications are semi-persistent schedulings,
Current schedule information is then preserved, the business is carried out on identical running time-frequency resource position every the fixed cycle
The transmission or reception of data.
Existing 3GPP transmitting uplink datas technology is to ensure big bandwidth, the mobility of H2H communication users
The flexibility of demand and scheduling and design, applied to the caller simultaneously of the great amount of terminals that is triggered by business
When Internet of Things is applied, mainly have a disadvantage that：
1st, excessive ascending control channel expense：After terminal is setting up connection with network, existing 4G LTE
Network is in order to ensure that user can be at any time rapidly to network side application uplink transmission resource, it is necessary to be each use
Family maintains a set of uplink control channel resource to send dispatch request, and H2H terminal-pair ascending control channels make
It is higher with frequency, and MTC terminal is relatively low to the frequency of use of ascending control channel, particularly with by business
The Internet of Things application of the great amount of terminals of triggering caller simultaneously, such as DR alarm scene, terminal user almost can
Apply for upstream data resource simultaneously in synchronization, remaining most of the time will in a dormant state.Therefore,
The method for distributing single ascending control channel for each user will greatly waste uplink bandwidth resource.
2nd, excessive down control channel expense：Ascending resource assigns instruction by down control channel PDCCH
Carrying, it is usual one instruction scheduling unique user single transmission (dynamic dispatching) or unique user it is many
It is secondary transmission (semi-persistent scheduling or pre-scheduling), due to H2H communicate in user's single transmission data volume compared with
Greatly, the expense of control channel still receives.But the single data volume of MTC business transmission is smaller,
And Relatively centralized at the time of transmission, traditional scheduling mode is applied to MTC using will bring huge control
Channel overhead.
3rd, unnecessary signaling consumption：Because the data volume that MTC service is transmitted is smaller, and base station is according to industry
The type of business can understand the size of terminal uplink data volume in advance, therefore use extra BSR signaleds base
The size of terminal buffers of standing data will bring unnecessary signaling consumption in MTC service application.
