Description
Technical field
The present invention relates to the communications field, in particular to a kind of method for configuring reference signal in unauthorized frequency range and
Device.
Background technique
Mobile communication system refers to operator by disposing wireless access network equipment (such as base station) and equipment of the core network (such as
Home location register, Home Location Register, HLR) etc., communication service is provided for user terminal UE (such as mobile phone)
System.Mobile communication experienced the first generation, the second generation, the third generation, the forth generation communication technology.Specifically, the first generation is mobile logical
The cellular telephony standard that letter refers to initial simulation, only limits voice communication, mainly using analogue technique and frequency division multiple access
The cut-in method of (Frequency Division Multiple Access, FDMA)；Generation Mobile Telecommunication System introduces number
Technology improves network capacity, improves speech quality and confidentiality, with " global system for mobile communications " (Global System
For Mobile Communication, GSM) and " CDMA " (Code Division Multiple Access, CDMA
It IS-95) is representative；3G (Third Generation) Moblie refers mainly to CDMA2000, and tri- kinds of technologies of WCDMA, TD-SCDMA are more with code point
Location is as access technology；The standard of forth generation mobile communication system is relatively uniform in the world, is International Organization for standardization
Long term evolution (Long Term Evolution/Long the Term Evolution-Advanced, LTE/LTE- that 3GPP is formulated
A), downlink be based on orthogonal frequency mostly directly enter (Orthogonal Frequency Division Multiple Access,
OFDMA), uplink mostly directly enters (Single Carrier-Frequency Division Multiple based on single carrier frequency division
Access, SC-FDMA) access way reached down peak magnitude according to flexible bandwidth and adaptive modulation coding scheme
Rate 1Gbps, the high-speed transfer of upstream peak rate 500Mbps.The basic framework of mobile communications network as shown in Figure 1, eventually
End (such as computer or mobile phone) is connect by accessing net with core net, and core net is crossed return link with access Netcom and communicated.
At this stage in LTE (release-10 to release-12), base station eNB passes through periodicity sending CSI-RS
The channel shape of (Channel State Information Reference Signal) for user terminal UE measurement different antennae
State.(the channel state measurement reference signal sub-frame configuration CSI-RS- in such as table 1 is configured according to wireless communication control RRC signaling
SubframeConfigICSI-RSCorresponding column), user terminal UE can obtain the week of channel state measurement reference signal CSI-RS
Phase (5ms, 10ms, 20ms, 40ms, 80ms, such as the CSI-RS periodicity T in table 1CSI-RS(subframes) respective column
In information) and the number of subframe subframe in the cycle (channel state measurement reference signal subframe is compiled in such as table 1
Number CSI-RS subframe offset △CSI-RS(subframes) information in corresponding column) and one, place resource block RB
In the position resource unit RE, as shown in Figure 2.When LTE use unauthorized frequency range (e.g., the LAA in release-13:

For transmitting CSI-RS), but eNB does not have to be what the UE was configured in each 10ms after channel competition
Downlink signal is sent on subframe, for the UE, (e.g., is led to by blind Detecting or according to eNB if UE can ignore
Crossing the instruction that other channels are sent) then its equivalent CSI-RS period causes because of increasing by the CSI-RS that can not send
Channel status estimates performance decline (more serious when channel competition user is more)；Can not if UE not can ignore that
The CSI-RS of transmission and the running time-frequency resource of configuration is estimated, will lead to channel status estimation completely mistake and influence after
The continuous scheduling performance based on CSI feedback.

The resource location where CSI-RS is sent with data after function, UE carries out channel according to the resource location of L1 signaling dynamic instruction
Estimation, still, when the UE quantity supported simultaneously is more, L1 signal resource expense can become very big, to reduce spectrum efficiency.
For the above-mentioned big problem of physical layer signaling resource overhead in unauthorized frequency range, effective solution is not yet proposed at present
Certainly scheme.
