-- the applying date of original application: on March 31st, 2014
-- the application number of original application: 201410126623.3
-- the invention and created name of original application: transmission method and device in a kind of unlicensed band
Technical field
The present invention relates to the schemes that unlicensed spectrum communication is utilized in wireless communication system, more particularly to based on LTE
The communication means for unlicensed spectrum (Unlicensed Spectrum) of (Long Term Evolution, long term evolution)
And device.
Background technique
LTE system supports P-CSI (Periodic Channel Status Indicator, periodic channel state instruction)
With A-CSI (Aperiodic CSI, aperiodic channel status instruction).Wherein, P-CSI is in PUCCH (Physical Uplink
Control Channel, Physical Uplink Control Channel) on transmit, A-CSI is transmitted on PUSCH.The reference resources of the CSI
It is CRS (Cell Reference Signal, cell reference signals) or CSI-RS (Channel Status Indicator
Reference Signal, channel status indicate reference signal), wherein the parameter of CRS is by cell physics ID
(Identifier, identifier) mark, the parameter of CSI-RS is configured by high-level signaling.
Base station sends DCI (Downlink Control Indicator, downlink control instructions) and triggers A-CSI, the DCI
It is uplink scheduling DCI, i.e., its format is one of DCI format { 0,4 }.For UE (User Equipment, user equipment),
If receiving the scheduling DCI of triggering A-CSI, send for measurement RS (Reference Signal, the reference in configuration cell
Signal) A-CSI, it is described configuration cell be it is described scheduling DCI scheduling serving cell either by high-level signaling configure clothes
Business cell list.Above-mentioned serving cell includes a descending carrier, it is also possible to including a up-link carrier.The descending carrier and
The up-link carrier is semi-statically configured by high-level signaling.
Traditional third generation cooperative partner program (3GPP -3rd Generation Partner Project) LTE system
In, data transmission can only occur on authorization frequency spectrum, however as increased dramatically for portfolio, especially in some urban areas,
Authorization frequency spectrum is likely difficult to meet the needs of portfolio.62 plenary sessions of 3GPP RAN discuss a new research topic, i.e.,
The comprehensive research (RP-132085) of unlicensed spectrum, main purpose is the dependent of LTE of the research and utilization in unlicensed spectrum
(Non-standalone) it disposes, so-called dependent refers to that the communication in unlicensed spectrum wants and authorize the service on frequency spectrum small

Component Carrier), the serving cell in unlicensed spectrum is deployed in as secondary carrier (SCC-Secondary
Component Carrier).For unlicensed spectrum, it is contemplated that uncontrollable/prediction of its interference level, UE may be matched
Set more carrier waves at the same use DFS (Dynamical Frequency Selection, dynamic spectrum selection) mode (
To stator frame) partial carrier wave is selected from optional carrier wave is used for transmission data.
Following problems may be encountered in the communication of unlicensed spectrum for traditional C/S I scheme:
Base station when no physical layer data is sent periodicity sending for CSI estimation downlink RS (such as CRS or
CSI-RS larger interference) is caused to other communication equipments in unlicensed spectrum, and if when no physical layer data is sent
It does not send and will receive larger limitation for the application of downlink RS, the DFS technology of CSI estimation, such as to be difficult to realize sub-frame level other
DFS。
The maximum bandwidth (100MHz) that the bandwidth of unlicensed spectrum may be supported much larger than LTE system, correspondingly, P-CSI
Excessive PUCCH resource may be occupied, particularly in view of PUCCH will be also likely to exist only in PCC (Primary in future
Carrier Component, main carrier)
