Description
Technical field
The present invention relates to wireless communication technology fields, pass more particularly to the scheduling of exempting from a kind of electric power wireless communication system
Transmission method.
Background technique
In traditional electric power wireless communication system, the uplink process based on scheduling is generallyd use.User equipment is first
Scheduling request first is sent to base station, for for new data transfer request ascending resource.After receiving scheduling request, base station is learnt
User equipment has data to need to transmit, but base station have no knowledge about at this time user equipment caching in data bulk, so can to
A uplink authorization is fed back at family, that is, distributes to a certain number of ascending resources of user equipment, user equipment will use this uplink
It authorizes to base station and sends buffer status report, the data number for needing to transmit in the uplink caching for providing user equipment to base station
Amount.Based on the information in buffer status report, base station can distribute sufficient amount of ascending resource for user equipment, so that user
Equipment can send the data in caching.
The above-mentioned uplink process based on scheduling can bring biggish data transmission delay, be unable to satisfy delay requirement compared with
High business demand.In order to avoid delay problem caused by the uplink process based on scheduling, exempts from scheduled transmission mechanism and obtain
Extensive concern and research.
Exempt from scheduled transmission to realize, base station needs for ascending resource to be pre-assigned to user equipment, and in order to reduce resource
Waste, the same ascending resource would generally be pre-assigned to multiple user equipmenies.When the upstream data of some user equipment arrives
Up to when, the user equipment can be used predistribution resource send data.But if multiple user equipmenies are just in the same resource
Upper transmission data, then collision problem will be generated.When the conflict occurs, if user equipment transmission can not be successfully decoded out in base station
Data, it is necessary to execute re-transmission, this exempts from the time delay of scheduled transmission by dramatically increasing.
In order to alleviate above-mentioned collision problem, user equipment when scheduled transmission is exempted from execution, using orthogonal code to data into
Row extension.If multiple user equipmenies of simultaneous transmission have used different sequence spreadings, base station is just capable of detecting when more
The data of a user device transmissions.In this case, the length of sequence spreading is longer, and optional sequence spreading is more, that
The probability that sequence spreading clashes will substantially reduce, and transmission success rate will significantly improve, although it also means that user equipment
The transmission occupied running time-frequency resource of data is more, and power consumption is higher.And in electric power wireless communication system, due to different service types
There is different propagation delay times to want summed data packet size, exempt from scheduled transmission using above-mentioned, it is difficult to meet time delay, the money of different business
Source demand cannot also improve the efficiency for exempting from scheduled transmission.
Summary of the invention
The invention mainly solves the technical problem of providing exempting from scheduled transmission method in a kind of electric power wireless communication system,
It can satisfy time delay, the resource requirement of different business, improve the efficiency for exempting from scheduled transmission.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of electric power wireless communication system is provided
Exempt from scheduled transmission method in system, comprising: base station is the transmitting extended sequence that different service types configure different length, wherein
The length of the corresponding transmitting extended sequence of the type of service that delay requirement is higher or data packet is smaller is longer, delay requirement it is lower or
The length of the corresponding transmitting extended sequence of the bigger type of service of data packet is shorter；Base station is by the corresponding difference of different service types
The transmitting extended sequence of length is sent to the user equipment in cell；Base station is that user equipment is allocated in advance for carrying out exempting to dispatch
The ascending resource of transmission；When the upstream data of user equipment reaches, user equipment is selected according to the type of service of upstream data
Corresponding transmitting extended sequence, and after being extended using the corresponding transmitting extended sequence to upstream data, on described
The upstream data after extension is sent in row resource.
Preferably, the transmitting extended sequence of the corresponding different length of different service types is sent in cell by the base station
User equipment the step of specifically: base station is by broadcast channel by the transmitting extended of the corresponding different length of different service types
Sequence is sent to all user equipmenies in cell.
Preferably, the transmitting extended sequence of the corresponding different length of different service types is sent in cell by the base station
User equipment the step of specifically: base station is by dedicated channel by the transmitting extended of the corresponding different length of different service types
Sequence sends one or more user equipmenies in cell.
Preferably, the base station is that user equipment periodically allocates ascending resource in advance, wherein the base station is divided every time
The ascending resource matched is identical or different.
Preferably, when user equipment selects corresponding transmitting extended sequence according to the type of service of upstream data, if on
The corresponding transmitting extended sequence of the type of service of row data be it is multiple, then user equipment from the multiple transmitting extended sequence with
Machine selects a transmitting extended sequence.
Preferably, user equipment sent on the ascending resource extension after upstream data before, further includes: described
Lead code is sent on ascending resource, the lead code is used to indicate the corresponding transmitting extended sequence.
It is in contrast to the prior art, the beneficial effects of the present invention are: base station is that different service types configure different length
The transmitting extended sequence of degree, makes that delay requirement is higher or the lesser business of data packet is able to use longer sequence spreading, with drop
The probability of low sequence spreading conflict improves transmission success rate；And delay requirement is lower or the biggish business use of data packet is shorter
Sequence spreading, to reduce resource occupation, and the power consumption of terminal is reduced, so as to meet time delay, the resource need of different business
It asks, improves the efficiency for exempting from scheduled transmission.
Detailed description of the invention
Fig. 1 is the flow diagram for exempting from scheduled transmission method in the electric power wireless communication system of the embodiment of the present invention.
