" flexibly duplex " technical support business it is adaptive, part downlink data is sent in uplink band, thus sufficiently benefit
With uplink frequency spectrum resource, meet the inconsistent demand of the uplink and downlink rate of business in network.
Fig. 1 is the flow diagram of communication means one embodiment the present invention is based on flexible duplex technology.With reference to Fig. 1,
The communication means of the present embodiment the following steps are included:
Step S102, base station set the data sender of full downlink to will be upper for the band downlink of one group of symmetrical spectrum
Line frequency section be set as uplink and downlink mixing data sender to.
Wherein, since FDD technology has one group of symmetrical frequency spectrum resource, the present embodiment based on flexible duplexing skill
The communication means of art can be applied in FDD network environment.
Step S104, the ascending-descending subframes configuration information of base station broadcast uplink band, wherein uplink and downlink of uplink band
Frame configuration information includes the ascending-descending subframes percent information of uplink band and the protection interval configuration of downlink and uplink transfer point
Information.
For the ascending-descending subframes allocation problem of uplink band, due to current TD-LTE (Time Division Long
Term Evolution, timesharing long term evolution) frame structure in downlink subframe it is more, if directly apply or use for reference arrive FDD's
It is limited to will lead to upstream rate for uplink band.Therefore, the present embodiment propose it is a kind of suitable for FDD etc. have symmetrical spectrum it is upper
The ascending-descending subframes configuration method of line frequency section, can make full use of uplink spectrum, and upstream rate will not be made limited.Wherein, on
The ascending-descending subframes percent information of line frequency section can be the form of allocation list, and the ascending-descending subframes structure allocation list of uplink band is such as
Shown in table 1:
The ascending-descending subframes structure allocation list of 1 uplink band of table
Wherein, D indicates that downlink subframe, U indicate that sub-frame of uplink, ms indicate millisecond.0~5 kind of uplink band is shown in upper table
Ascending-descending subframes percent information, when subframe is configured to 0~4, incompatibility enable (at this point, not supporting flexible duplex capability
Terminal can not be linked into this cell), when subframe is configured to 5, incompatibility is invalid (at this point, not supporting flexible duplex capability
Terminal can also be linked into this cell).The ascending-descending subframes configuration information of uplink band is only that incompatibility enables Shi Caiyou
Effect.
Wherein, downlink and uplink transfer point refer to the downlink subframe for needing to send upstream data after downlink data transmission.?
In the present embodiment, downlink downlink subframe corresponding with uplink transfer point contains two parts in the time domain, and a part is several
According to hop, another part is protection interval.The downlink of uplink band and the protection interval of uplink transfer point match confidence
Breath for example, the ratio of downlink and TCP data segment and protection interval in the corresponding downlink subframe of uplink transfer point, it should
Percent information can be configured in the broadcast by base station.Wherein, TCP data segment is used for transmission customer-specific data (such as user's industry
Business data), do not include control channel and broadcast channel, and be not used to transmission high-level signaling.Wherein, it is not connect in protection interval
Receive or send any data.The protection interval plan of establishment of the present embodiment can be such that available transmission time maximizes, and improve
The efficiency of frequency spectrum.
Fig. 2 shows the subframe structure schematic diagrames that 0~4 corresponding uplink band is configured in the embodiment of the present invention.Wherein, D table
Show that downlink subframe, U indicate that sub-frame of uplink, GAP indicate protection interval.For the ease of implementing, duration of each subframe can be with
It is identical.
In step S104, base station can also broadcast non-compatible information simultaneously, and non-compatible information, which is used to indicate, does not support spirit
The terminal of duplex capability living can not be linked into the cell, and non-compatible information includes whether to enable having for incompatibility and incompatibility
The effect phase.
After if terminal does not support flexible duplex capability, discovery base station to enable incompatibility, if being currently idle state
Cell reselection is carried out, and using the cell as the Target cell for forbidding access within the validity period of incompatibility.
If terminal supports flexible duplex capability, terminal reports its ability information to base station, for notifying this terminal of network
To the support situation of flexible duplex capability, and after discovery base station enables incompatibility, further sent in parsing broadcast upper
The ascending-descending subframes configuration information of line frequency section.Wherein, the ability information that terminal reports for example, whether support flexibly duplexing function
It can, support the frequency range number of flexibly duplex.
When the configuration of the ascending-descending subframes of the uplink band of base station changes, base station updates the broadcast message of itself, and
Activated state terminal is notified by high-level signaling (such as radio resource control RRC message) and passes through page notification Idle state terminal.
If not supporting the Idle state terminal discovery broadcast message update of flexibly duplex and non-compatible information enabling (i.e. cutting from configuration 5 by base station
Change to 0~4 any configuration), then it is immediately performed cell reselection.For not supporting the activated state terminal of flexible duplex, if discovery
Broadcast message updates and non-compatible information enables, and base station carries out the release for eating dishes without rice or wine to connect, and handle using high-level signaling instruction terminal
Relevant gravity treatment configuration information is indicated to terminal.Base station and terminal newly configure all in accordance with the time point application of agreement, when next
When moment subsequent subframe will apply new configuration information, if it find that the re-transmission subframe of terminal can not during uplink
The position of re-transmission is found according to old HARQ sequential relationship, then terminal abandons this re-transmission, and wait the scheduling of base station to indicate, and base
It stands to reschedule for terminal and retransmits data transmission frame number.
Step S106, base station receive the ability information for supporting the terminal of flexible duplex capability to report, ability information are saved
In the contextual information of the terminal.
Step S108, base station is according to the ability information of terminal by the control channel of band downlink to supporting flexibly duplexing function
The terminal of energy sends the downlink control instructions information of downlink data transmission in uplink band.
Wherein, it for the scheduling problem of downlink subframe in uplink band, takes and utilizes the control channel in band downlink
The mode being scheduled, this is because if the downlink subframe in uplink band still continues to use traditional mentality of designing, wherein must
It must include control channel, spectrum efficiency can be reduced in this way, and the interference feature in uplink band and traditional down direction
Interference feature has very big difference, and traditional control channel performance is not necessarily able to satisfy design requirement.Also, traditional carrier wave is poly-
It can not continue to be applicable in using the scheme that carrier wave indicating bit (CIF) distinguishes carrier wave in conjunction, therefore, the embodiment of the present invention also introduces newly
Identifier with distinguish carrier wave polymerization in cross-carrier scheduling, to have effectively achieved the resources control for uplink band.
Wherein, the downlink control instructions information of downlink data transmission includes the following contents in uplink band:
1) whether resource block belongs to uplink band, this information is only effective to downlink transfer；
2) position of resource block and size；
3) currently used process number number, when it is implemented, 3bit can be set in such as up direction, down direction can
4bit is arranged；
4) (Hybrid Automatic Repeat Request mixes automatic weight by the modulation system on resource block and HARQ
Pass request) redundancy versions.
Step S110, terminal match confidence according to the ascending-descending subframes of the downlink control instructions information and this cell uplink frequency range
Breath receives the downlink data that downlink subframe of the base station in uplink band is sent.
In the communication means based on flexible duplex technology, when causing data not to be correctly received for some reason
When, then it also needs other side to retransmit data, can usually use HARQ technology.For on the timing relationship of HARQ, flexible duplex skill
The feedback sequential relationship of art, it is all different with current TDD and FDD from subframe structure, from the point of view of the HARQ of uplink,
Unlike TD-LTE its can be found on band downlink within the set time downlink subframe carry out ACK (confirmation)/
NACK (non-acknowledgement) feedback is not necessarily sub-frame of uplink in the 4th subframe after NACK/ACK feedback unlike FDD.From
From the point of view of downlink HARQ, it is not necessarily sub-frame of uplink in the 4th subframe after first pass unlike FDD, thus not necessarily
There is ACK/NACK feedback time point.Therefore flexibly the HARQ sequential relationship of duplex technology needs to redesign, and is specifically described below.
Base station and terminal carry out the re-transmission of upstream data according to the HARQ strategy of up direction；Base station and terminal are according to downlink
The HARQ strategy in direction carries out the transmission of downlink data.
Wherein, the HARQ strategy of up direction includes: that base station is scheduled the uplink of terminal, and terminal is on receiving
The nearest sub-frame of uplink after 3 subframes after the scheduling result of row transmission sends data, and base station is fed back in n-th of subframe
ACK/NACK information is retransmitted in the n-th+Kre subframes if necessary to retransmit terminal, wherein being equal to 4 using Kre when configuration 5, is adopted
It is as shown in table 2 with Kre value when configuration 0~4:
The relation table of ACK/NACK and re-transmission time point during 2 uplink of table

| 3 | 6 | 6 | 6 | 6 | 6 | |||||
| 4 | 4 | 5 | 5 | 4 | 5 | 5 | 5 |
Wherein, the HARQ strategy of downlink transfer includes: that base station sends data in n-th of subframe, and terminal is in the n-th+K sons
Feeding back ACK/nack message on frame, when base station is using configuration 5, K is equal to 4, as shown in table 3 using K value when configuration 0~4:
The relation table with ACK/NACK subframe is just passed in 3 downlink transmission process of table
| Configuration | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
