Description
Technical field
The present invention relates to Long Term Evolution advanced system (LTE-Advanced, Long Term Evolution Advanced
System the information transmission technology), more particularly to a kind of physical hybrid ARQ indicator channel in LTE-Advanced
(PHICH) transmission method and device of symbol data.
Background technology
In order to be measured to the quality of channel and the data symbol of reception is demodulated in LTE Release8/9
Public reference signal (CRS, Common Reference Signal) is devised, user equipment (UE, User Equipment) can
To carry out the measurement of the channel of quality in UE connection status by CRS, so as to determine UE progress cell reselections and be switched to target
Cell, when disturbing rank higher, physical layer can be disconnected by high-rise related Radio Link connection failure signaling.
In order to further improve gulping down for the average availability of frequency spectrum of cell and the cell edge availability of frequency spectrum and each UE in LTE R10
Rate is told, respectively defines two kinds of reference signals：Channel information reference signal (CSI-RS) and demodulated reference signal (DMRS), its
In, CSI-RS be used for channel measurement, by the measurement to CSI-RS can calculate UE need to eNB feedback precoding square
Battle array index (PMI, Precoding Matrix Indicator), channel quality information instruction (CQI, Channel Quality
) and order instruction (RI, Rank Indicator) Indicator.DMRS is used for the demodulation of DSCH Downlink Shared Channel, is solved using DMRS
Adjusting can be using the interference between the different receiving sides of method reduction of wave beam and different districts, and can reduce code book granularity and make
Into hydraulic performance decline, and because not having to additional PMI symbol expense in Physical Downlink Control Channel, reduce to a certain extent
The expense of descending control signaling.
In LTE R8, R9 and R10 Physical Downlink Control Channel (PDCCH) be mainly distributed on subframe preceding 1 or 2 or
3 OFDM (OFDM) symbols, specific distribution need to match somebody with somebody according to the port number of different subframe type and CRS
Put, as shown in table 1, table 1 sets forth the downlink resource block number of the port number configuration according to different subframe type and CRS
MeshThe OFDM symbol number of PDCCH more than 10 and no more than 10.
Table 1
Each receiving side needs first three symbol in Downlink Control Information to carry out blind check, the original position of blind check, control
The element number of channel is relevant from the wireless network temporary identifications and different control information of distributing to receiving side.Typically can be with control
Information processed is divided into publicly-owned control information and proprietary control information, and publicly-owned control information is typically placed in Physical Downlink Control Channel
Public search space, proprietary control information can be placed on public search space and dedicated search space.Receiving side is after blind check
Judge to whether there is common control information, descending scheduling or uplink scheduling information in present sub-frame.Due to Downlink Control Information
Repeat requests (HARQ) feedback is not mixed, so needing to ensure that the bit error rate of detection is low as far as possible.
Under LTE R10 heterogeneous networks, because different base station type has stronger interference, it is contemplated that macro base station (Macro
ENodeB) interference problem to micro-base station (Pico) and Home eNodeB (Home eNodeB) are to macro base station (Macro eNodeB)
Interference problem, it is proposed that solve the problem that interferes between different type base station using the silent method of resource, specifically
Resource silence method can be divided into silence (Muting) method based on subframe, such as：ABS method, based on resource element
Method, the method based on resource element such as CRS silences method.
Above-mentioned resource silence method not only adds the waste of resource, and brings great limitation for scheduling,
Particularly when considering Macro eNodeB ABS configurations, if Pico distribution is more, the ABS of Macro eNodeB configurations
It is more, it can so be brought greater impact to Macro eNodeB, the wasting of resources can be increased while add scheduling delay.And
The interference of different control channel data resources can be reduced under ABS for control channel, but can not solve CRS resource sums
According to the interference problem of resource, can not solve interference between data resource for silent CRS method, and this method is backward
Compatibility is bad, while adding access delay, it may be necessary to more standardization efforts.
More users may be introduced in the LTE R11 stages to be sent out in multicast single frequency network (MBSFN) subframe
Send, will so cause MBSFN to configure the off-capacity for the PDCCH that 2 OFDM symbols can carry, in order to ensure to R8/R9/
The backwards compatibility of R10 user in Physical Downlink Shared Channel (PDSCH) resource, it is necessary to open up new transmission control information
Resource, and coordinated multipoint transmission (COMP) technology is introduced in the R11 stages, this technology can solve by way of space division
Interference problem between this different type cell, and resource overhead is saved, the silent wasting of resources brought is avoided, is subtracted
Few limitation to scheduling.But be can not solve this problem by the method for space division in the way of current time domain PDCCH,
And must retain in view of the backwards compatibility to R8 and R9, the mode of this control channels of time domain PDCCH, it is at this moment how sharp
Need to carry out careful research come the interference solved between control channel with spatial division technology.In view of current progress, considers
Downlink Control Information is sent in PDSCH resources, capacity is limited and interference problem although so solving, and can bring PHICH
The problem of resource is not enough.
