Technical field
The present invention relates to the communications field, in particular to transmission and the choosing method and the device of the virtual signaling group of a kind of detection reference signal.
Background technology
Long Term Evolution (Long Term Evolution abbreviates LTE as) system is after having experienced R8, R9, the several versions of R10, and R11 version technology begins one's study again.At present, part R8 version product begins progressively commercial, and R9 version and R10 version have pending further product programming.Experiencing R8 version and R9 version after two stages, the R10 version has increased a lot of new characteristics again on the above two basis, for example, demodulated reference signal (Demodulation Reference Signal, abbreviate DMRS as), channel state information reference signals (Channel State Information Reference Signal, abbreviate CSI-RS as) etc. the pilot tone characteristic, transmission and feedback characteristicss such as 8 antenna supports, particularly presence of intercell interference is offset and is strengthened (enhanced Inter-Cell Interference Cancellin, abbreviate eICIC as) on the basis of the ICIC of technology in having considered R8 version and R9 version, further considered the interference avoidance technique between the sub-district.For the technology that solves interference problem between the sub-district, consider mainly that at the initial stage in stage of R10 version the area interference under the homogenous networks avoids, especially mainly considered eICIC technology and multipoint cooperative (Coordinated Multi-point abbreviates CoMP as) technology.The CoMP technology is meant that a plurality of node cooperations send data to one or more UE at identical running time-frequency resource or different running time-frequency resources, and this technology has advantages such as the interference that reduces between the sub-district, the throughput that improves cell edge and expansion sub-district covering.But, owing to considered heterogeneous network introduced the situation under more scenes, the complexity of CoMP technology in that the later stage is discussed, and the time restriction of R10 version discussion, final decision is not introduced extra CoMP standardized content at the R10 release phase, when design CSI-RS, can consider to design in conjunction with the demand of CoMP part, therefore, the CoMP technology is not just carried out further discussion after the 60bis meeting.
LTE has defined Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviate PDCCH as) carrying scheduling distribution and other control information, each PDCCH is by several control channel unit (Control Channel Element, abbreviate CCE as) to form, the CCE number of each subframe is by quantity and the downlink bandwidth decision of PDCCH.
UE obtains PDCCH by blind Detecting in the search volume, and the search volume is divided into common search space and UE dedicated search space.Wherein, the common search space is meant the zone that all UE can search, and this space carries the sub-district Proprietary Information; The dedicated search space is the spatial dimension that single UE can search, and a plurality of UE dedicated search space might be overlapping, and still, the general initial searching position of each UE is different.Usually, UE is before carrying out blind check, the base station sends to UE by high-level signaling and notifies to inform UE UE mode of operation that will adopt and cyclic redundancy check (CRC) (the Cyclic Redundancy Check that is used for PDCCH, abbreviate CRC as) Radio Network Temporary Identifier (Radio Network Temporary Identity the abbreviates RNTI as) type of scrambling.

Feedback technique with the CoMP system in 3GPP TS 36.814 is divided three classes, wherein, utilize detection reference signal (Sounding Reference Signal, abbreviate SRS as) to carry out obtaining channel information time division duplex (Time Division Duplex abbreviates TDD as) based on channel reciprocity be a kind of important feedback technique in the CoMP system.In addition, SRS also is a kind of important channel sounding techniques (also belonging to feedback technique) in the up CoMP system.The problem of the SRS off-capacity of bringing based on many antennas has been introduced detection reference signal aperiodic (Aperiodic-Sounding Reference Signal abbreviates A-SRS as) in the R10 version.
For example, in CoMP scene 4, be provided with a plurality of Microcells (that is: sub-district under the RRH) in the macrocell (Macro Cell), like this, just increased the focus covering power and the blind spot covering power of macrocell, made macrocell can support more user to communicate with respect to traditional homogenous networks sub-district.But, because macrocell all has identical cell ID (Cell ID) with all RRH under its coverage, that is to say, the macrocell that is provided with a plurality of Microcells still uses the virtual signaling group of SRS with the same traditional of homogenous networks sub-district, therefore, still there is SRS off-capacity problem for 4 times in the CoMP scene.
In order to solve the problem of above-mentioned SRS off-capacity, need not only to consider that SRS is used for the situation of the selection of up precoding, modulation coding mode and scheduling, and, also need to consider in the TDD system, to be used for the situation of the selection of descending precoding, modulation coding mode and scheduling.Yet, when carrying out the power control of SRS for the capacity of expanding SRS, especially for the different receiving node in the asymmetric scene of up-downgoing transfer of data, need UE to adopt the power control of different SRS to seem particularly important.
At present, in order to overcome the above problems, disturb minimizing enhancing and three factors of SRS power control to consider solution in conjunction with the enhancing of SRS capacity, SRS usually:
(1) for enhancing of SRS capacity and SRS interference minimizing enhancing, can comprehensively consider, mainly exist following four kinds to solve thinkings:
Thinking one, configuration be based on the SRS sequential parameter of UE-Specific, is root sequence of sequence separate configurations (that is, the root sequence of this root sequence and PUCCH is independently) of SRS that is:;
The capacity that thinking two, consideration increase SRS can dispose a plurality of SRS symbols, notifies UE the SRS number of symbols that it will adopt by high level or physical layer signaling;
Thinking three, consider to utilize quadrature mask (Orthogonal Cover Code, abbreviate OCC as) mode come dilatation SRS, if disposing two SRS symbols can consider to carry out spread spectrum based on time domain OCC mode, that is: can take the situation of two OFDM symbol transmission SRS for same UE, pilot frequency sequence on two SRS symbols need carry out the time domain spread spectrum according to the mode of walsh sign indicating number, if consider SRS symbol of configuration, can consider the spread spectrum based on frequency domain, that is: a UE two adjacent resource elements on frequency domain can utilize walsh to carry out the time domain spread spectrum;
Thinking four, consideration increase the reuse factor of SRS, increase pectination carrier wave indication (comb) span of SRS, in present standard that is:, the comb value of SRS can get 0,1, represent different frequency domain comb respectively, and for the enhancing of comb, can consider the comb value is extended to 0,1,2,3, like this, in same Resource Block, can accomplish to support at most the frequency domain quadrature of 4 user SRS.
(2), mainly exist following two kinds to solve thinking at the control of SRS power:
Thinking one, configuration when UE utilizes SRS to carry out different link circuit self-adaptings, can be utilized different power control factor based on the power contorl parameters of the SRS of UE-Specific;
Thinking two, configuration when UE utilizes SRS to carry out the compensation of upstream node received power, can adopt different power control factor based on the power contorl parameters of the SRS of UE-Specific.
Though prior art disturbs minimizing enhancing and three aspects of SRS power control to provide several different solution thinking of solution SRS off-capacity problem from the enhancing of SRS capacity, SRS, but, do not propose a kind of effective, concrete ripe solution and deal with SRS off-capacity problem under the asymmetric scene of up-downgoing transfer of data.
