Technical field
This application involves the communications field more particularly to a kind of method and devices for transmitting data.
Background technique
With the popularization of intelligent terminals, business abundant drives mobile bandwidth (full name in English: Mobile Broadband English
Text abbreviation: MBB) flourish, network flow increases in explosive.According to mobile research institute's consultation report, with regard to hot zones
For, total flow in 2016 will be more than 30 in 2012 times or more.Meanwhile MBB data throughput also proposed it is higher
It is required that.And the MBB service traffics of 70-80% occur indoors, operator needs emphasis to solve asking for indoor throughput hoisting
Topic.
According to existing standard agreement, for random access channel (full name in English: Random Access Channel, English
Abbreviation: RACH) resource, base station is periodically scheduled, and it is fixed to occupy frequency spectrum resource, allow user to carry out random access.Agreement
The maximum cycle for providing RACH is 20ms, i.e., every 20ms resource can or can not initiate access procedure regardless of user, which all can be by
It is fixed to occupy once.Under common scenario, in order to ensure the effect of access, the RACH period is arranged to 10ms.
In the MBB epoch, as indoor business is more and more important, flow accounting is increasing, the more efficient benefit of radio resource
Increasingly fierce to promote the demand of flow, RACH process has the section of Optimal improvements under many scenes.In-door covering is special
Point: uplink and downlink flow is big, and mobility is few, and access RACH signaling procedure is few, and coverage area is small.
The original intention of agreement protects the process of random access well, so that the occupancy of the higher priority of user-network access provides
Source carries out Network Synchronization.But this also results in many wastings of resources when ensureing networking user's timeliness: with one group of number
For, the RACH period is arranged to 10ms, and average each RACH occupies 6 resource block RB resources, then one second has 600
RB is occupied, the 10s time, just there is 6000 RB, and each RB is 712bps, flow 6000*712=4Mbps in 10s, each
Stand one day add up to get off waste carrying handling capacity theory reach as high as 34560Mbps, cause the biggish wasting of resources.
Summary of the invention

In existing standard agreement, RACH resource is configured periodically to be used for transmission RACH demand signalling, and maximum week
Phase is 20ms, and resulting in RACH resource can frequently be dispatched.But under indoor scene, not multiple terminals need frequent
Access base station, so the maximum cycle configuration of RACH resource is cancelled in base station in the method for the data transmission of the application.In order to protect
Card is able to use the RACH resource when there is terminal to need to access, and the base station is that the RACH resource is matched according to the actual situation
The period for being used for transmission RACH demand signalling is set, when in the transmission RACH demand signalling moment in period, the base station is then broadcasted
The RACH resource, the access for terminal.The period size for being used for transmission RACH demand signalling is configurable, and can be configured to the second
Grade or more, different scenes carry out different configurations: such as passback scene, the configuration period is 2S, and small bandwidth scenarios, the configuration period is 1S,
Middle-size and small-size office space, configuration period are 2S, and home scenarios, the configuration period is 10S etc..
303, when the base station determines that current time is the moment in period of non-transmitting RACH demand signalling, the base station configuration
RACH resource is used for transmission data；
Due to transmission RACH demand signalling priority be higher than transmission data priority, in order to avoid RACH resource by
Interference, cause terminal can not access base station, so the base station is when configuring RACH resource and being used for transmission data, first judgement is current
Whether the moment is the moment in period of non-transmitting RACH demand signalling, if it is not, then configuring the RACH resource is used for transmission data, if
It is then to configure other channel resources to be used for transmission data.
304, when the base station determines that the RACH resource is unoccupied, the RACH resource is dispatched to described in the base station

Detailed content is referring to described in step 104.
306, when the base station determines that current time asks for transmission RACH according to the period of the transmission RACH demand signalling
When seeking signaling, the base station carries out the demodulation of RACH demand signalling to the RACH resource, if demodulation RACH demand signalling success,
Then connection is established with the second terminal for initiating the RACH demand signalling；Alternatively, when the base station is asked according to the transmission RACH
When the period of signaling being asked to determine that current time is non-transmitting RACH demand signalling, the base station carries out data to the RACH resource
Cyclic redundancy check code CRC demodulation；
It is configured by the period that RACH resource is used for transmission RACH demand signalling by base station, and base station is carrying out base band
When demodulation, just it has been determined that terminal sends the time of data, when base station carries out data demodulation to RACH resource at the appointed time, just
Can determine that whether current time is transmission RACH demand signalling, is asked if so, the base station then carries out RACH to the RACH resource
The demodulation of signaling is asked, if it is not, the base station then carries out the demodulation of data to the RACH resource.
In the embodiment of the present application, biggish transmission RACH request letter is configured according to actual scene for RACH resource by base station
The period of order improves the utilization rate of RACH resource so that the RACH resource more time is used for transmission data.
