Description
Technical field
The present invention relates to the methods, devices and systems that wireless communication technology field more particularly to a kind of dynamic cell cover.
Background technology
In long term evolution (LTE, Long Term Evolution) system, radio access technology is connect in communication system
One important technology of receipts machine access control, receiver complete the correction of uplink Timing Synchronization, Yong Hugong by random access procedure
Rate adjusts and the application of user resources demand.
The uplink random access lead of LTE uses the cyclically shifted sequences of ZC (Zadoff-Chu) sequence, connects at random
Entering lead code is passed through derived from the different cyclic shift of selection based on ZC sequences.Random access subframe is made of three parts, point
It is not cyclic prefix part, leader portion and protection interval part.
Coverage radius of cell is bigger, and signal transmission time delay is bigger.Therefore according to the difference of MPS process, required cycle
Prefix length is different, leading and protection interval length is also different.Existing LTE system supports five kinds of formats, is format 0-4 respectively,
Each format corresponds to different MPS process.Coverage radius of cell is common by the cyclic shift and protection interval of random access subframe
It determines.Existing LTE random access guidings maximum supports that radius is 100 kilometers of MPS process.
If covering radius is R, antennas orthogonal plane half-power angle is A, and antenna tilt B can then calculate antenna height
Degree H is H=R*tan (B-A/2), it is possible thereby to release when coverage radius of cell is 100 kilometers, antenna height needs up to a hundred
Rice.And when positioned at seashore, if to be built on sandy beach, so high station is extremely difficult, at this time can be by the building on seashore
Or mountain carries out antenna and hangs height, but cell can cover a sea part at this time, and the practical covering in sea is caused to be reduced.It therefore can be with
Consider covering being divided into two parts, be controlled by two base stations.As shown in Figure 1, base station is covered according to original covering needs
Lid radius is all areas of R2, and covering radius is very big, if the cell half supported no more than LTE random access guiding maximums
Diameter, then have greatly covering all on land, and the covering very little on sea.Therefore overlay area is divided into two parts,
Radius is that the inner ring of R1 is covered by a base station, and radius is that the annular section of R1 to R2 is covered by a base station, the half of R1 to R2
Diameter can reach the maximum radius of LTE random access guidings support, and the radius of inner ring R1 can be adjusted dynamically according to actual needs.

According to the time delay value for needing to adjust, delay compensation is carried out to receiving data and/or transmission data in time domain；After delay compensation
Data carry out receive and/or transmission processing；Memory is coupled at least one processor.
Using this programme, the inner ring radius of society of annular coverage cell can be adjusted according to actual environment situation dynamic, and
And annular covering outer shroud can reach the maximum magnitude supported when round covering with inner ring radius of society difference maximum magnitude.Meanwhile it should
Scheme increases only inner ring radius time delay and determines and inner ring radius delay compensation unit, and after delay compensation, the original circle in base station is covered
The processing module and flow of lid can be multiplexed completely, it is easy to accomplish.In addition, the present invention can only do uplink time delay compensation, also may be used
Only to do downlink delay compensation, uplink and downlink delay compensation can also be carried out at the same time；Uplink and downlink compensates simultaneously to be advantageous in that up and down
Row has respectively shared the work of a part of delay compensation, and pressure of the only unilateral compensation to Time Delay of Systems processing capacity can be effectively relieved
Power.
