Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing the present invention is made into
One step ground is described in detail, it is clear that described embodiment is only some embodiments of the invention, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
Various aspects are described herein in connection with terminal and/or base station.Terminal, refers to and provides a user with voice and/or data
Connective equipment (device), including wireless terminal or catv terminal.Wireless terminal can be with wireless connecting function
Portable equipment is connected to other processing equipments of radio modem, through wireless access network and one or more cores
The mobile terminal that net is communicated.For example, wireless terminal can be mobile phone (or being " honeycomb " phone) and with movement
The computer of terminal.And for example, wireless terminal can also be portable, pocket, hand-held, built-in computer or vehicle-mounted
Mobile device.For another example, wireless terminal can (English be for movement station：Mobile station), (English is access point：
Access point) or user equipment (English is：User equipment, abbreviation UE) a part.
In the prior art, in time division duplex (Time Division Dulplexing, abbreviation TDD) system, up letter
Road has symmetry characteristic with down channel.Therefore, base station can be with equivalent by the uplink channel information that uplink channel estimation is obtained
Descending channel information for needed for.In order to aid in uplink channel estimation, terminal is in up channel launch channel detection reference signal
(Sounding Reference Signal, SRS), the Sounding Reference Signal is generated using specific pseudo-random sequence,
Such as Zadoff-Chu (ZC) sequence, and terminal and the known sequence generation information in base station.Up-link sends ZC sequences
Afterwards, base station carries out coherent detection and demodulation using the signal sequence received by corresponding ZC sequence pairs, estimates up channel
CSI (Channel State Information, channel status symbol).Using resulting CSI, base station can carry out pre-
The MIMO signals such as coding, beam shaping treatment operation, with the spectrum efficiency of lifting system.Due to the quantity of orthogonal pseudo-random sequence
It is limited, therefore cannot ensure that the pseudo-random sequence that different terminals are distributed is completely orthogonal.In this regard, side of the base station using various multiplexings
Formula is terminal distribution SRS resource.SRS resource maps and distribution method is one of important design problem in practical communication system.
3G (Third Generation) Moblie partner program (3rd Generation Partnership Project, referred to as 3GPP) is formulated
The corresponding Long Term Evolution (Long of Evolved Universal Terrestrial Radio Access (E-UTRA) agreement
Term Evolution, referred to as LTE) system has corresponding SRS resource to map and distribution method.Specifically, SRS resource
Refer to pseudo-random sequence that SRS is used, specially send frequency domain, time domain, code domain resource of SRS etc..Such as, frequency domain multiplexing side
Method includes Comb Pilot, frequency hopping etc., code domain multiplexing method include to same pseudo-random sequence by different cyclic shifts (CS,
Cyclic shift) the multiple pseudo-random sequences of generation etc..
Fig. 2 gives a kind of schematic diagram of Comb Pilot, and in a time slot, odd subcarriers resource allocation is to terminal 1
SRS1 is sent, even subcarriers resource allocation sends SRS2 to terminal 2, and wherein SRS1 and SRS2 can be same pseudo-random sequence
Row.Although SRS resource can be multiplexed, LTE system is still present the situation of SRS resource shortage.Such as, in same time slot,
At most 16 filled bands of support SRS transmittings wide, correspond to 2 Comb Pilots and the difference puppet generated by 8 different CS
Random sequence.In same cell, base station is that different terminals distribute orthogonal SRS resource, and thus terminal is sent out in up-link
When penetrating SRS, the SRS from different terminals that base station receives is orthogonal, so as to base station can do correct channel estimation obtain
To the CSI of up-link.However, the terminal distribution of different districts to SRS resource be probably it is non-orthogonal, that is, occur SRS money
The situation of source conflict.Such as, on same running time-frequency resource, the pseudorandom sequence that the SRS of the different districts of LTE system distribution is used
Row adjust CS and obtain according to different ZC roots sequences.Although same ZC roots sequence is orthogonal after different CS are adjusted,
It is that the pseudo-random sequence obtained by different ZC roots sequences is but non-orthogonal.Also, distribution and the cell of different districts root sequence
Number (cell id) is relevant.Therefore, the SRS resource of different districts is non-orthogonal.
Therefore, the embodiment of the present invention for different districts when SRS resource is configured, it is regular by different districts according to setting
SRS resource is configured to mutually orthogonal resource, and this makes it possible to avoid, the uplink SRS signal of the terminal from different districts is mutual
Interference, specifically, as described in Figure 3, the embodiment of the present invention provides a kind of SRS resource collocation method schematic flow sheet, specifically real
Existing method includes：
Step S301, it is determined that carrying out the adjacent area of co-located with first community, and determines the adjacent area is configured first
SRS resource subset；
Step S302, obtains second in addition to the first SRS resource subset from default SRS resource set
SRS resource subset, wherein, the default SRS resource set is the configuration parameter identical SRS resource set for previously generating；
Step S303, the SRS resource in the second SRS resource subset is allocated to be linked into the first community
Terminal, so that the SRS resource that the terminal in the SRS resource that accesses of terminal in the first community and the adjacent area is accessed is mutual
It is orthogonal.
It should be noted that the first community mentioned in the embodiment of the present invention refers to wherein in network overlay system
Individual cell, is that one kind refers to, and adjacent area is then cell that is adjacent with first community position or may disturbing, or is passed through
Interference level etc. determines adjacent category relation.
In step S301, Neighboring Cell List is determined according to neighboring BS relationship, and the cell in the Neighboring Cell List is defined as
The adjacent area of the first community；Or, according to the configuration information that user sets, the cell that will be included in the configuration information determines
It is the adjacent area of the first community.
That is, first community receives the mark of the adjacent area of the terminal to report in first community coverage, and by institute
The corresponding adjacent area of mark is stated as the adjacent area for carrying out with the first community co-located.
Or be that user first configures to the adjacent area of first community, determining can be led to first community
The adjacent area of letter, then first community the cell in user configuration information is defined as the adjacent area of co-located.
Further, Fig. 4 gives 2 schematic diagrames of cycle SRS resource, and the SRS resource in a cycle includes resource
0th, resource 1, resource 2, resource 3, resource 4, resource 5, resource 6, resource 7, wherein, these resources are orthogonal resources.This hair
Bright embodiment combination Fig. 5 is illustrated to above-mentioned SRS resource collocation method, and specifically, Fig. 5 includes four base stations, is respectively
First base station, the second base station, the 3rd base station and the 4th base station, each base station carry a cell, the SRS moneys needed for each base station
Source is 2, four base stations eventually through adjacent area self-configuring, being configured to neighboring BS relationship each other.
Before step a, the T0 moment, four base stations in Fig. 5 do not go up electricity, and at the T0 moment, electricity completes adjacent in first base station
With postponing, due to now there was only first base station, therefore first base station does not have neighbor base station, now means 8 SRS resources pair in area
All be can use for first base station, 2 SRS resources are only needed due to first base station, therefore first base station selects two SRS at random
Resource, it is assumed that first base station picks resource 0, resource 1, after having selected, then completes the SRS moneys of the corresponding cell 0 of first base station
Source configures.
Step b, the T1 moment, if after electricity completes neighbor cell configuration on the second base station, because now first base station is existing, because
After this second base station detects first base station, adjacent area is completed each other and is mutually configured, now the SRS moneys of the second base station inquiry first base station
After the configuring condition of source, learn that resource 0, resource 1 are occupied, therefore, the second base station is any from remaining six SRS resources
Select two of which, it is assumed that the second base station picks resource 2, resource 3, after having selected, then complete the corresponding cell 1 in the second base station
SRS resource configuration.
Step c, subsequent third base station, the 4th base station still complete the SRS configurations so cell using similar step b.
From above-mentioned steps as can be seen that using SRS resource configuration strategy provided in an embodiment of the present invention, it is ensured that four
The SRS resource non-overlapping copies of cell, realize that SRS resource mutual exclusion is configured, thus for multi-cell coordination is detected in each cell eventually
The SRS signal at end provides technical support, and the measurement of cell coordination position fixing process SRS signal is in the absence of interference, it is ensured that multi-cell coordination
The possibility of positioning such that it is able to multi-plot joint positioning terminal.
Assuming that cover two cells below a base station, as described in Figure 6, first base station coverage cell 0 and cell 1,
Two base stations coverage cell 2 and cell 3, the SRS resource needed for each cell are 2, and four cells utilize first base station and second
Base station eventually through adjacent area self-configuring, being configured to neighboring BS relationship each other.
Step 1, T0 moment, after electricity completes neighbor cell configuration in first base station, due to now there was only first base station, therefore first
Base station does not have neighbor base station, now means that 8 SRS resources all can use for first base station, due to first base station covering
Two cells, it is only necessary to 4 SRS resources, therefore first base station is random selects two SRS resources and be allocated to cell 0, it is assumed that the
One base station picks resource 0, resource 1 and is allocated to cell 0, and after having selected, first base station selects two from resource is left again
SRS resource is allocated to cell 1, it is assumed that first base station picks resource 2, resource 3 and is allocated to cell 1.
Step 2, the T1 moment, if after electricity completes neighbor cell configuration on the second base station, because now first base station is existing, because
After this second base station detects first base station, adjacent area is completed each other and is mutually configured, now the SRS moneys of the second base station inquiry first base station
After the configuring condition of source, learn that resource 0, resource 1, resource 2, resource 3 are occupied, therefore, the second base station is from remaining 4
Arbitrarily two of which is selected in SRS resource, it is assumed that the second base station picks resource 4, resource 5, after having selected, then complete the second base
The SRS resource configuration of corresponding cell 2 of standing.
Step 3, follow-up second base station still completes the SRS configurations so cell 3 using the method for similar step 2, will
Resource 6, resource 7 are allocated to cell 3.
Further, it is contemplated that the diversity of network overlay system, the first SRS resource that the adjacent area is configured is determined
It is that first community receives the adjacent area that the adjacent area is transmitted directly to the first community is configured first to collect a kind of mode
The mark of SRS resource, and the first SRS resource subset that the adjacent area is configured is determined according to the mark；Or another kind side
Formula is that the first community receives the mark of the first SRS resource configured on the adjacent area forwarded by third party device,
And the first SRS resource subset that the adjacent area is configured is determined according to the mark.
Such as, the 3rd base station can be that the adjacent base station first base station of the 3rd base station of reception and the second base station are sent respectively to
The second base station in the configured SRS resource mark, or Fig. 5 of the 3rd base station can as third party device, the 3rd
The configured SRS resource that base station receives the transmission of the second base station is identified, and the first base station of the second base station forwarding is configured
SRS resource is identified.The second way can relatively reduce the number of times of the interaction between base station compared to first way, save
Signaling consumption.
Further, the first community is according to the priority of the terminal in cell, preferentially by second SRS resource
The SRS resource of concentration is allocated to the terminal of high priority, as shown in figure 5, if the terminal in T4 moment, the 4th base station is
3 because the SRS resource that can configure altogether of the 4th base station is 2, therefore, now, the 4th base station according to the priority of terminal,
For 2 terminals of high priority configure corresponding SRS resource 4 and SRS resource 5.
In addition, the SRS resource in the second SRS resource subset is allocated to be linked into the first community by first community
After interior terminal, also include：The shared information of the mark on second SRS resource is generated, it is true in order to other cells
The SRS resource that the fixed first community is configured.That is, after first base station configures SRS resource in Figure 5, will
Configured SRS resource information of the generation on first community, similarly, the second base station, the 3rd base station, and the 4th base station can
Mark of the generation on itself configured SRS resource of corresponding cell, so, base station below can obtain in time has matched somebody with somebody
