Description
Technical field
The present invention relates to the communications field, ascending HARQ during in particular to a kind of newly-increased backhaul subframe
(HybridAutomatic Repeat Request, hybrid automatic repeat-request) method and device.
Background technology
RN is introduced in LTE-A (Long Term EvolutionAdvanced, senior long evolving system) system
New link is added after (Relay Node, via node), as shown in figure 1, wherein, the link between eNode-B and RN
Chain between referred to as backhaul link (back haul link or repeated link), RN and UE (UserEquipment, user equipment)
The link that road is referred to as between access link (access link), eNode-B and UE is referred to as directlink (direct transfer link).
When using inband-relay (with interior relaying), i.e., eNode-B to relay links and relay to UE links are transported
Make in identical frequency resource.Because inband-relay launching opportunities produce interference (self-interference) to the receiver of oneself,
So eNode-B to relay links and relay to UE links are impossible in identical frequency resource simultaneously, unless there are
Enough Signal separators and isolation between antennas.It is similar, relay be also impossible to while the data that UE is launched are received again to
ENode-B launches.The solution of one possible transmitting-receiving interference problem is so that relay is receiving the number from eNode-B
According to when, not to UE carry out transmitting operation, that is to say, that needed after relay to UE links increase " gap ", by configuring MBSFN
(Multicast Broadcast Single Frequercy Network, Multicast Broadcast Single Frequency Network) subframe is used for
Backhaul subframe so that UE is operated in " gap " time range without any reception/transmitting, and Relay exists
Completion is transmitted into the switching of reception in " gap " time range, in OFDM (Orthogonal below after the completion of switching
Frequency Division Multiplexing OFDMs) data of the symbol reception from eNode-B.Exist at present
Backhaul is used for using MBSFN subframe in LTE (Long Term Evolution, long evolving system)
Subframe, its specific mode is：MCE (MBMS Control Entity, multimedia control entity) gives eNode-B first
Available MBSFN subframe are configured, eNode-B configures available in these available MBSFN subframe again
backhaul subframe。
According to the regulation in current LTE system, as shown in Fig. 2 subframes of 1 10ms radio frames frame by 10 1ms
Subframe is constituted, it may include Unicast (unicast) and Multicast Broadcast (multicast and broadcast), wherein in FDD
During (Frequency Division Duplex, FDD) mode, #0, #5 subframe are used as transmitting synchronizing signal, and #4, #9
Subframe is used as paging (paging), and in TDD (Time Division Duplex, time division duplex) mode, #0, #5 subframe are used as
Launch synchronizing signal, and #1, #6 subframe are used as paging, that is to say, that for FDD { #0, #4, #5, #9 } subframe, TDD { #0, #
1st, #5, #6 } subframe has above-mentioned specific use, so cannot be used for MBSFN subframe distribution, i.e., in 1 radio frames
Assignable MBSFN subframe are up to 6 subframe subframe in frame.That is, always having 4 in 1 radio frames
Individual subframe cannot be used for backhaul transmission, and backhaul time resource utilizes both insufficient or dumb, it appears that just
Seem " timehole (time cavity) ".FDD standards in existing lte-a system, corresponding backhaul subframe distribution is using 8bits's
The binary system of bitmap modes, i.e. 8bits corresponds to different backhaul subframes configurations respectively, but 8bits bitmap to DL
Subframe index (Down Link subframe index, descending sub frame index) are invalid for { #0, #4, #5, #9 }.1
In individual radio frames in addition to above-mentioned 6 subframes, (i.e. DL subframe index are the corresponding son of #0, #4, #5, #9 to other subframes
Frame) if transmission for backhaul, these subframes are referred to as newly-increased backhaul subframe.
In LTE system, the transmission between user equipment and base station for data needs to set up HARQ (Hybrid
Automatic Repeat Request, hybrid automatic repeat-request) process and fed back accordingly.When base station receives use
After the data of family equipment, base station generates downlink feedback information ACK/NACK (Acknowledgement/ according to decoding cases
Negative Acknowledgement0, confirmed/non-confirmed number) or (Up Link grant, uplink authorization information),
ULgrant mainly includes NDI (New Data Indicator, new data is indicated), MCS (Modulation and Coding
Scheme, Modulation and Coding Scheme), the information such as RA (Resource Allocation, resource allocation), it is and above- mentioned information is descending
It is sent to user equipment.User equipment is further processed according to the information received, if receiving ACK, or receives NDI
=1 or 0 (1,0 implication represented can flexibly be set), then continue to transmit new data, if receiving NACK, or receive NDI
=0 or 1, then data will be resend to base station in identical HARQ processes.Specifically, being had in existing lte-a system
The corresponding HARQ of 256 combined situations enters number of passes, as shown in table 1, wherein the combination configuration in the 1st row uses the decimal system,
For example " 170 " represent 8bits bitmap binary system be " 10101010 ", then it represents that descending sub frame index for " 1 ", " 3 ",
Together, corresponding ascending HARQ course number is 3 for " 5 ", " 7 " corresponding subframes combine.After newly-increased backhaul subframe during ascending HARQ
Sequence will be changed, it is necessary to re-start setting, and effective solution is not yet proposed at present for this problem.
