Description
Technical field
The present invention relates to wireless communication technology, particularly a kind of method and apparatus of user's definite response Channel Processing response message.
Background technology
Automatically request retransmission (ARQ, Automatic Repeat reQuest) is a kind of transmission mechanism that is used for guaranteeing the reliability transmitted, and is current when once attempting bust this, just requires retransmission data packet may.HARQ (HybridARQ) is the improvement of ARQ agreement, in the ARQ system, introduced a FEC subsystem exactly, this FEC subsystem is to be used for correcting a mistake to reduce the number of times of re-transmission, Deng stopping SAW (Stop and Wait) is the simplest a kind of HARQ form: transmit leg only just begins to handle next data block after the data block that sends is correctly received, the recipient should be transmitted one to transmit leg and is used to the response message of indicating transmission block whether to be correctly decoded, be generally and confirm correct information and confirm error message (ACK/NAK, ACKnowledgement/Negative AcKnowledgement), bit of the general use of this confirmation.It is the HARQ process of carrying out N SAW on a channel simultaneously side by side that N passage etc. stops HARQ (N-channel-SAW-HARQ).When down link was used for transmission data block by certain HARQ process, up link was used to transmit the response message of other HARQ processes.
For making the user receive the data that the base station issues accurately, the certain information relevant with Data Receiving of user need be prenoticed in the base station, and this information relevant with Data Receiving also is called dispatch, generally comprises:
The resource allocation indication information generally takies 7 bits;
The IIARQ procedural information generally takies 3 bits;
User terminal identity information ID (UE ID, User Equipment Identity) generally takies 16 bits.
After above-mentioned dispatch was issued by the base station, the user is identification UE id information at first; After the position of determining receives the data that send to oneself, to handle through receiving, verification judges whether the data that receive are correct; The user is according to check results feedback response message ACK/NAK, and these a plurality of response messages that come from different user are to give the base station by each user specific response Channel Transmission separately.Issue from dispatch, need through propagation delay time, and the recipient receive reciprocal according to after data processing time, so and schedule information have certain time interval between moment of corresponding response message constantly.
Cross in scheduling process and to have different scheduling modes, a kind of is dynamic dispatching: each transfer of data of user all has corresponding dispatch notice; Another kind is a scheduling mode of saving the control signaling: in order to save the expense of control signaling, introduce some and saved the scheduling mode of control signaling, such as: persistent scheduling (persistent scheduling), schedule information sends constantly at some, and all the other constantly use known schedule information according to established rule.
Because data transmission resources is shared, also share so wish responder link: promptly a user monopolizes certain responder link.So, when a user need handle response message, when being generally transmission or receiving response message, need know which bar responder link oneself uses.
Because there are relativeness in logic in a user's dispatch and other users' dispatch, so during feedback response message ACK/NAK, also can be with reference to this relation, clash collision when avoiding feeding back between the user, do not need extra signaling again: the relativeness between the responder link of multi-user data is consistent with the relativeness that the multi-user of these data of scheduling controls between signaling channel, as shown in Figure 1.
The process of user's definite response channel comprises in the prior art:
Send these a plurality of users' that are dispatched to dispatch;
Whether each user has the dispatch that sends to oneself according to set rule searching;
The user who finds dispatch determines the logical place of the responder link of oneself according to the logical place of the dispatch that sends to oneself in these all dispatchs;
Each is worked as the inferior user who is dispatched to and all sends or receive response message according to the logical place of determined responder link.
For example: if a user's dispatch sends on the 3rd control signaling channel, this user just selects the 3rd responder link to send or receives response message ACK/NAK so.
But, said method is applicable to the scene of dynamic dispatching, and for the scheduling mode of saving the control signaling, certain user's transfer of data does not have the dispatch indication in the current time transmission unit, these users can't determine and other users' responder link between relativeness, can't select suitable responder link.
