Description

Distribution method and the system of physical mixed adaptive retransmission request indicating channel resource

Technical field

The present invention relates to the communications field, relate in particular to distribution method and the system of a kind of physical mixed adaptive retransmission request indicating channel (Physical HARQ indicator Channel is referred to as PHICH) resource.

Background technology

In LTE Release 8/9 for the quality of channel being measured and the data symbol that receives being carried out demodulation, designed public reference signal (Common Reference Signal, referred to as CRS), subscriber equipment (User Equipment, referred to as UE) can carry out by CRS the measurement of channel, thereby determine that UE carries out cell reselection and switches to Target cell, and carry out the measurement of channel quality in the UE connection status, when disturbing rank higher, physical layer can disconnect by the relevant Radio Link connection failure signaling of high level.In LTE Release 10 (referred to as LTE R10), in order further to improve the average availability of frequency spectrum in residential quarter and the throughput of the cell edge availability of frequency spectrum and each UE, two kinds have been defined respectively with reference to signal: channel information reference signal (Channel State Information Reference Signals, referred to as CSI-RS) and demodulated reference signal (Demodulation Reference signal is referred to as DMRS).Wherein, CSI-RS is used for the measurement of channel, by the measurement to CSI-RS can calculate UE need to be to the base station (EnhancedNode B, referred to as eNB) feedback pre-coding matrix index (Precoding MatrixIndicator, referred to as PMI), channel quality information indication (Channel Quality Indicator, referred to as CQI) and order indication (Rank Indicator is referred to as RI); DMRS is used for the demodulation of DSCH Downlink Shared Channel, utilize the DMRS demodulation can utilize the method for wave beam to reduce interference between different receiver sides and the different districts, and can reduce the hydraulic performance decline that the code book granularity causes, and reduced to a certain extent the expense (because need not add the overhead bit of PMI at Physical Downlink Control Channel) of descending control signaling.

Physical Downlink Control Channel mainly is distributed in

front

1 or 2 or 3 OFDM of a subframe in LTE R8, R9 and R10, and concrete distribution need to configure according to the port number of different subframe type and CRS, and is as shown in table 1.

The OFDM number of symbols of table 1PDCCH

Each receiver side need to carry out blind check at first three symbol, and temporarily sign is relevant with different control information from the wireless network of distributing to receiver side for the original position of blind check, the element number of control channel.Usually, can be divided into publicly-owned control information and proprietary control information to control information, publicly-owned control information generally is placed on the public search space of Physical Downlink Control Channel, and proprietary control information can be placed on public search space and dedicated search space.Receiver side judges whether have common control information, descending scheduling or uplink scheduling information in current subframe after blind check.Because this Downlink Control Information does not have the HARQ feedback, so, need to guarantee that the error rate that detects is low as much as possible.

Under LTE R10 heterogeneous network, because the different base station type has stronger interference, considered macro base station (Macro eNodeB) to the interference problem of little base station (Pico) and Home eNodeB (Home eNodeB) to macro base station (Macro eNodeB) interference problem, the method that has proposed to utilize resource to mourn in silence solves the mutual interference problem between the dissimilar base station, the concrete resource method of mourning in silence based on (Muting) method of mourning in silence of subframe (for example can be divided into, the method of ABS) with based on the method for mourning in silence of resource element (for example, CRS mourn in silence method).

Yet, above method has not only increased the waste of resource, and brought great restriction for scheduling, particularly when the ABS configuration of considering Macro eNodeB, if the distribution of Pico is more, the ABS of Macro eNodeB configuration is more, brings larger impact can for like this Macro eNodeB, can increase the wasting of resources and increase simultaneously the scheduling time delay.And, for the method for control channel under ABS, although can reduce the interference of different control channel data resources, can't solve the interference problem of CRS resource and data resource; For the method for the CRS that mourns in silence, can't solve the interference between the data resource, and this method backwards compatibility is bad, when having increased access delay, may need more standardization effort.

May introduce more user at Multicast Broadcast Single Frequency Network (Multicast Broadcast Single Frequency Network in the LTE R11 stage, referred to as MBSFN) send on the subframe, will cause like this 2 OFDM (Orthogonal Frequency Division Multiplexing of MBSFN configuration, referred to as OFDM) symbol Physical Downlink Control Channel (the Physical Downlink Control Channel that can carry, referred to as PDCCH) off-capacity, in order to guarantee the backwards compatibility to R8/R9/R10 user, need to be at Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) resource of opening up new control information transmission on the resource, and introduced coordinate multipoint (Coordinated Multi Point in the R11 stage, referred to as COMP) technology, this technology can solve by the mode that sky divides the interference problem between this dissimilar residential quarter, and saved resource overhead, the wasting of resources that having avoided mourns in silence brings reduces the restriction to scheduling.

But, mode according to present time domain PDCCH is to address this problem by the method that sky divides, and consider backwards compatibility to R8 and R9, the mode of this control channel of time domain PDCCH must keep, at this moment, the interference that how to utilize empty minute technology to solve between the control channel need to be carried out careful research.In view of the discussion progress of up-to-date meeting, consider to send Downlink Control Information in the PDSCH zone, although the capacity that solved like this is limited and interference problem, may bring the another one problem, that is, and the problem that the PHICH resource is not enough.So, be necessary the enhancing technology of PHICH is further studied.
