Description
Technical field
The present invention relates in field of communication technology more particularly to a kind of LTE network data transmission restoration methods, terminal and
System.
Background technology
In long term evolution（Long Term Evolution, abbreviation LTE）In network, user equipment（UE）I.e. terminal accesses
After network system, to initiate data transmission, need to send a scheduling request to base station first（SR）, terminal can utilize uplink
Control channel sends scheduling request and distributes uplink shared channel resources to base station requests, after base station receives the scheduling request, when
Have upstream data it is pending when, distribution uplink shared channel resources carry out transmitting uplink data to terminal, for terminal.
Base station can send wireless distribution message before allocating resources to terminal and carrying out transmitting uplink data to terminal（RRC）,
The carrying of wireless distribution message has issued scheduling request resources configuration information and measurement gap（GAP）Resource allocation information, for true
That determines scheduling request resources sends position and the position of measurement gap resource.
Include mainly scheduling request configuration index I in scheduling request resources configuration informationSR, scheduling request sending cycle and its
Subframe position is by configuration index ISRIt determines, specific formula for calculation is as follows：
（10×SFN+subframe-NOFFSET,SR）modSRPeriodicity=0
Wherein, SFN is the System Frame Number that scheduling request is sent, and subframe is that scheduling request sends subframe numbers, NOFFSET,SR
For scheduling request sub-frame offset, SRPeriodicityIt, can be by the configuration index I in such as the following table 1 for scheduling request sending cycleSR
It arrives.
Table 1
Measurement gap resource is the resource defined in LTE network in order to support different frequency/different standard synchronous and measurement.Terminal
Once into measurement gap resource time, any uplink and downlink transmission would not allow for.There are two types of period moulds for measurement gap resource
Formula, period are respectively 40ms and 80ms, and the measurement gap resource allocation information issued by base station determines which kind of pattern used.It measures
No matter gap is all fixed as 6ms by which kind of cyclic pattern of resource duration.Measurement gap resource allocation information includes mainly measurement gap
Resource period, measurement gap resource sub-frame offset gapoffset etc., the initial position of measurement gap resource is according to measurement gap
Measurement gap resource period, measurement gap resource sub-frame offset gapoffset in resource allocation information are calculated, specific to count
It is as follows to calculate formula：
SFN mod T = FLOOR(gapoffset/10)；
subframe = gapoffset mod 10；
Wherein, it is measurement gap resource starter system frame number that T, which is 1/10th, SFN of measurement gap resource period,
Subframe is measurement gap resource initial subframe number.SFN and subframe codetermines the initial position of measurement gap resource.
Inevitably exist between the scheduling request resources that base station is sent to terminal and measurement gap resource and rushes
Prominent situation, such as when measurement gap resource period is 80ms, measurement gap resource sub-frame offset gapoffset=0, scheduling request
Configuration index ISRWhen=78, the system frame number SFN mod 8=0 of measurement gap resource is calculated according to above-mentioned formula, between measurement
It is subframe 0 that gap resource, which originates subframe, no matter and due to measurement gap resource duration, which kind of cyclic pattern is all fixed as 6ms, then it surveys
Amount gap resource occupies 0 ~ subframe of subframe 5 this 6 subframes altogether.
And by the table of comparisons 1, the sending cycle of scheduling request is also 80ms, and further according to calculation formula, scheduling request is sent
System frame number SFN mod 8=0, scheduling request sub-frame offset NOFFSET,SR=ISR- 75=3, then it is that scheduling request, which sends subframe,
3 subframes namely subframe 3.
From the foregoing, it will be observed that the System Frame Number of scheduling request is identical with the System Frame Number of measurement gap resource（It is 0）, and
The transmission subframe of scheduling request is subframe 3, is fallen in the range of 0 ~ subframe of subframe 5 of measurement gap resource occupation, then scheduling is asked
The transmission position of resource is asked to be overlapped with the position of measurement gap resource.
Terminal would not allow for any uplink and downlink transmission once entering measurement gap resource time, and since scheduling is asked
It asks the transmission position of resource to be overlapped with the position of measurement gap resource, terminal is caused uplink control channel can not to be utilized to send scheduling
Request, also can not just carry out the transmission of any data using Uplink Shared Channel, so can not the carrier frequency residing for serving cell connect
Data are received, data-transmission interruptions are caused.
