Description
Technical field
The present invention relates to the communications field; Particularly; The feedback method that relates to a kind of HFDD (HalfFrequency Division Duplex, Half-Frequency Division Duplex) user's symmetry class transceiver mode HARQ (Hybrid Automatic Repeat reQuest, mixed automatic retransmission request).
Background technology
HFDD can adapt to spectrum allocation may flexibly, and is with low cost owing to not adopting duplexer to make simultaneously.GSM (Global System for MobileCommunications, the global system for mobile communications) terminal of widely adopting is exactly a kind of HFDD mode, this kind working method terminal circuit working mode that realized eating dishes without rice or wine, and GSM terminal transmitting-receiving relation is fairly simple.At the mobile radio system such as WiMAX (the Worldwide Interoperability for Microwave Access that with eat dishes without rice or wine packetizing and link circuit self-adapting are characteristic; Micro-wave access global inter communication) and LTE (Long Term Evolution; Long Term Evolution) introduce HFDD in and will consider the demand more more complicated, specifically be summarized as than GSM:
1, the unification of HFDD and FDD and TDD:
A) purpose is that HFDD, FDD and many kinds of duplex terminals of TDD realize simple;
B) HFDD terminal and FDD terminal coexist in same system; Therefore require HFDD and FDD should keep in full accord at public control section such as descending synchronizing channel, broadcast channel and PCH and uplink random access channel etc., the Subframe that therefore confirms as uplink and downlink at FDD should continue maintenance at HFDD;
C) also need keep the sequential relationship of FDD up-downgoing data channel and corresponding control channel; With LTE is that example keeps DL-SCH (Down Link-SynchronizationChannel exactly; Downlink Synchronization Channel) (PDSCH (Physical Downlink ShareCHhannel; Physical Downlink Shared Channel) and ACK/NACK, UL-SCH (PUSCH (Physical Uplink Share Channel; Physical Uplink Shared Channel)) and PHICH (Physical HARQ Indication Channel; Physical HARQ Indicator Channel) and the sequential relationship of PDCCH (Physical Downlink Control CHannel, Physical Downlink Control Channel) carrying UL grant and UL-SCH.
D) use the for example many ACK/NACK feedbacks of TDD thought thought.
2, the specific transceiver mode of user should keep stability after the preliminary examination assignment:
A) the specific transceiver mode (UE Specific transmission/receptionpattern) of user is meant the logical relation of user between receiving and dispatching;
B) no matter be continuous dispatching or dynamic dispatching, the specific transceiver mode of user should be just to decide after the preliminary examination assignment, can avoid a large amount of signaling assigned user transmitting-receiving relations like this;
C) after user's AD HOC was specified, user's dynamic just showed ground self adaptations such as frequency domain, modulation domain and antenna territory;
D) the specific transceiver mode of user mainly designs and considers the constraint of CCCH time slot according to the sequential relationship of FDD up-downgoing data channel and corresponding control channel.
3, the specific transceiver mode of user should be equally applicable to continuous dispatching and dynamic dispatching
4, the specific transceiver mode of user should be supported the asymmetric tenability of time-domain, the down link that agreement DL refers to, the up link that UL refers to, and then asymmetric support specifically comprises following 5 big types:
The 1st type, has only downlink data: i.e. DL Data Only+UL Control pattern
The 2nd type, has only upstream data: i.e. UL Data Only+DL Control pattern
The 3rd type, up-downgoing data symmetry: i.e. DL/UL Data+DL/UL Control pattern
The 4th type, descending be dominant asymmetric: promptly DL is dominant/UL Data+DL/ULControl pattern
The 5th type, up be dominant asymmetric: the i.e. DL/UL Data+DL/ULControl pattern that is dominant
5, different HFDD user's orthogonal multiplex
Fig. 1 shows the basic transceiver mode figure of prior art FDD.First data 101 are designated Datal, and second data Data2 sends behind a certain intervals N=24 Subslot.Behind an interval M=3 Subslot, provide ACK/NACK1 information 103 after receiving for first data 101 terminals; The base station obtains determining whether to retransmit after this information; If receive it is nack message; Then the base station resends data RT11 102, and similarly whether base station waits ACK/NACK2 and ACK/NACK3 decision carries out data RT 12 and the retransmit RT 13 for the third time second time.The time interval between 101 and 102 is defined as RTT (Round Trip Time, wireless transmission at interval).
Adopt discontinuous transmission and discontinuous receive mode to the technological terminal of eating dishes without rice or wine of packetizing in this; Being with the GSM fundamental difference that this discontinuity depends primarily on whether to feed back to retransmit changes; Among the figure 104,105 and 106 represent respectively the base station to the terminal once, the transceiver mode transmitted of secondary and three times success, the terminal is in reception, waits for and launches three kinds of states.
Can find out that from figure Data 2 and RT 13 are in same position, have avoided the arrangement of extra Subslot.
In realizing process of the present invention; The assigning method of user's transceiver mode that the inventor finds to provide in the prior art is only applicable to FDD or TDD; And HFDD has the advantages that to be different from FDD and TDD, so the HARQ feedback method of existing user's symmetry class transceiver mode can't be suitable for user's transceiver mode of HFDD.
Summary of the invention
The present invention aims to provide a kind of HARQ feedback method of HFDD user's symmetry class transceiver mode, and the HARQ feedback method that can solve existing user's symmetry class transceiver mode can't be suitable for the problems such as user's transceiver mode of HFDD.
