Abstract
The embodiment of the invention discloses a downlink extended transmission method and an uplink extended transmission method for F-FDD, and a system and a device for realizing the downlink/uplink extended transmission method. By adoption of the embodiment of the invention, an F-FDD user terminal or an F-FDD base station can utilize a plurality of sub-bursts to perform extended transmission of cross-data areas between a plurality of data areas in a frame, so that a subchannel can be occupied within continuous time in the frame to perform uplink and downlink extended transmission on user stations on the edge of a cell. Therefore, as for residual time-frequency resources which are not enough to be distributed as a burst in each data area, the residual time-frequency resources in the plurality of the data areas can be combined in a mode of combined encoding and used as a burst by the user stations. All the sub-bursts of F-FDD extended transmission users use the same extended transmission feedback channel, so that the feedback channel is better utilized and resource waste is reduced.
Description
Technical field
The present invention relates to networking technology area, the expanded transmission method of especially a kind of F-FDD and equipment.
Background technology
At present, the standard of IEEE 802.16e mainly is the support of H-FDD (Half duple FDD, half-duplex FDD) in the support of research for FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)).MS under the situation of FDD (Mobile Station, travelling carriage) can receive and dispatch simultaneously, and under the situation of H-FDD, MS can only receive or send out in the same moment.In order to support H-FDD to propose the frame structure of grouping, mainly contain following several frame structure in the present standard:
The frame structure of (1) two MAP (Map: shine upon), as shown in Figure 1;
The frame structure of (2) three MAP, as shown in Figure 2;
(3) based on the frame structure that exchanges three MAP that divide into groups, as shown in Figure 3.
Wherein, the M among the figure represents common MAP, the MAP of the group one that M1 represents, and that M2 represents is the MAP of group two.
User access network, the information that obtains own affiliated group needs later on to know that (MAP1, position MAP2) is so that receive for group MAP.So under the situation of two MAP, M1 need indicate the position of M2, common MAP need indicate the position of M1 and M2 under the situation of three MAP.
For the MS that is operated under the fdd mode, can be divided into F-FDD MS and H-FDD MS according to the difference of ability.F-FDD MS has two cover transmission circuits, and a cover is used for receiving data at band downlink, and a cover is used for sending data at uplink band, and this two covers circuit can be worked simultaneously.H-FDD MS has only a cover transmission circuit, or is operated in reception, or is operated in transmission.
At present the MAC (Medium Access Control, medium access control) of IEEE 802.16 supports polytype duplex mechanism, comprise TDD (Time Division Duplex: time division duplex), F-FDD and H-FDD.Wherein TDD represents frequency range of up-downgoing use of network, and travelling carriage can only receive or send in any one period, can not receive simultaneously and send; F-FDD represents two frequency ranges of up-downgoing use of network, and one is band downlink, and one is uplink band, and travelling carriage can send on uplink band when receiving band downlink; H-FDD represents that two frequency ranges are used in the up-downgoing of network, and one is band downlink, and one is uplink band, but travelling carriage can only be operated in uplink band or be operated in band downlink in some periods.Use the travelling carriage of F-FDD owing to can receive and dispatch simultaneously, to having relatively high expectations of travelling carriage; And use the travelling carriage of TDD or H-FDD owing to can only send or receive in certain period, can not receive and dispatch simultaneously, so lower the requirement of travelling carriage.
In the existing 802.16e standard agreement tdd mode is defined, the downlink transfer of using HARQ DL MAP IE to indicate HARQ and non-HARQ, this IE supports HARQ Chase, HARQ IR and three kinds of HARQ patterns of HARQ CC-IR.The data data area that HARQ DL MAP IE definition is one or more distributes the time slot of given number to give each burst in these data areas.All subburst in data zone only support a kind of HARQ pattern.The distribution of these time slots all is the rule according to time domain behind the first frequency domain in the data area.Each son burst all is separately to encode.Subburst for using three kinds of different HARQ patterns indicates with DL HARQ Chase Subburst IE, DL HARQIR CTC Subburst IE and DL HARQ IR CC Subburst IE respectively.
