Description

Uplink transmission data piece response message resource allocation methods and system

Technical field

The present invention relates to moving communicating field, relate in particular to a kind of uplink transmission data piece response message resource allocation methods and system.

Background technology

The develop rapidly of digital communication system is had higher requirement to the reliability of data communication, yet under abominable channel, especially in high data rate or the high-speed mobile environment, multipath interference and Doppler frequency-shift etc. seriously affect systematic function.Therefore, effective error-control technique, especially mixing automatic request retransmission (Hybrid Auto Repeat Request abbreviates HARQ as) technology just becomes the focus that the communications field endeavours to study.

In the HARQ mode, the sign indicating number that sends of making a start not only can error detection, but also has certain error correcting capability.After the receiving terminal decoder is received code word, at first check error situation,, then carry out error correction automatically if in the error correcting capability of sign indicating number; If mistake is a lot, exceeded the error correcting capability of sign indicating number, then can faults come out, receiving terminal is given the decision signal of making a start through feedback channel, requires to make a start retransmission of information.At ofdm system (Orthogonal Frequency Division Multiplexing; Abbreviate OFDM as) in; Through correctly reply/wrong responses (ACK/NACK) control signaling representes the correct or mistake of transmission, and need to judge whether to retransmit with this.

At third generation partner program (The 3rd Generation Partnership Project; Abbreviate 3GPP as) Long Term Evolution (Long Term Evolution; Abbreviate LTE as) Frequency Division Multiplexing system in; Down physical channel comprises Physical Control Format Indicator Channel, the automatic request retransmission indicating channel of Physical Downlink Control Channel and physical mixed (Physical Hybrid ARQ Indicator Channel abbreviates PHICH as) channel.Wherein, PHICH is used to transmit descending ACK/NACK information, as ascending physical signal shared channel (Physical Uplink Shared Channel, HARQ response message PUSCH).

At present, in LTE system uplink technology, a transmission block is supported at the terminal at most, and therefore, corresponding PHICH channel only needs the HARQ designator (HI) of 1 bit.When HI=1, represent correct confirmation, the base station has correctly received PUSCH; When HI=0, expression error check information, the incorrect PUSCH that receives in base station.The HARQ designator of this 1 bit is through coding, and modulation is mapped to corresponding PHICH channel again and gets on behind the spread spectrum.

Compare with existing system; Senior international mobile communication (International Mobile Telecommunications-Advanced abbreviates IMT-Advanced as) system will realize higher data rate and bigger power system capacity, promptly move at low speed; Under the focus coverage condition peak rate can reach 1Gbit/s (bps); In high-speed mobile, under the wide area coverage condition, peak rate can reach 100Mbit/s.In order to satisfy the requirement of ITU-Advanced, be asked to support bigger system bandwidth (reaching as high as 100MHz) and backward compatibility LTE existing standard as the senior Long Term Evolution of the evolution standard of LTE (LTE-A).Therefore; Thereby on the basis of existing LTE bandwidth, merge carrier aggregation (the Carrier Aggregation that obtains bigger bandwidth; Abbreviate CA as) technological one of the key technology in the LTE-A system that just becomes; Adopt this technology can improve the availability of frequency spectrum of IMT-Advanced system, it is in short supply to alleviate frequency spectrum resource, and realizes frequency spectrum resource optimization.

The LTE-A system satisfies the requirement of the uplink speed of IMT-Advanced, and the UE uplink can be supported a plurality of transmission blocks.According to present discussion, LTE-A system up, two transmission blocks of multipotency support of UE send simultaneously.Therefore, in corresponding downstream PHICH channel, need feed back two response messages of this UE at least.Current solution is that these two response messages are obtained a feedback signal after through logic and operation, adopts the existing method of LTE then, this feedback signal is placed in the corresponding PHICH channel sends.

In sum; Have following technical problem in the prior art: drawing through logic and operation because feedback signal is a response message according to two transmission blocks of UE, therefore, is NACK as long as the response message of a transmission block is wherein arranged; Then the feedback signal behind the logical AND is NACK just; Like this, UE need retransmit these two transmission blocks after receiving the NACK feedback signal, thereby will influence the throughput performance of up-link.

10. system as claimed in claim 8 is characterized in that,

Said resource distribution module is concrete to adopt following formula to calculate the frequency expansion sequence numbering that current PHICH group issues response message:

Wherein, i=0,1...M,

Be the size of PHICH modulation symbol spreading factor, when said response message is fed back through a corresponding PHICH group of downlink component carrier in said base station, S _Enable=0; When said response message is fed back through the corresponding PHICH group of a plurality of downlink component carriers in said base station, S _Enable=1.
