Description
Technical field
The present invention relates to the communications field, relate in particular to method and the device thereof of a kind of demodulation, transmission Physical Uplink Control Channel.
Background technology
At LTE (Long-Term Evolution, Long Term Evolution) in the system, PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) can be used for carrying following information: SR (Source Requestment, resource request) information, CQI (Channel Quality Indicator, cqi) information and ACK (Acknowledgement); The base station is that UE (User Equipment, user terminal) divides the resource (being the CQI resource) that is used in feedback CQI information and the resource (being the SR resource) that is used for feedback SR information semi-staticly, and the resource of distribution can comprise resource index and feedback sub-frame configuration etc.; When UE need send SR information, send PUCCH in the SR resource, carry SR information among this PUCCH; When UE need send CQI information, send PUCCH in the CQI resource, carry CQI information among this PUCCH.
UE feeds back CQI information according to feedback cycle configuration cycle property ground on the CQI resource of distributing, unless the situation of some conflict occurs; For receiving terminal, if only need detect CQI information, then directly carry out the PUCCH detection in the CQI resource and get final product.When base station scheduling during PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), need detect ACK information at corresponding sub-frame of uplink; Lose if PDSCH assigns, then may have the not problem of feeding back ACK information of UE reality; Therefore, the base station need also need to detect ACK information when the SR resource detects SR information when scheduling PDSCH, perhaps, also need to detect ACK information when the CQI resource detects CQI information.Stipulate according to agreement, when at UE information collision (be UE when needing simultaneously to send at least two information to be sent, be called information collision takes place) taking place, when clashing as SR information and CQI information, carry the PUCCH of SR information in the transmission of SR resource, and abandon CQI information; When if SR information, ACK information and CQI information clash, carry the PUCCH of ACK information in the transmission of SR resource, and abandon CQI information; When ACK information and CQI information clash, and the Simultaneous-AN-and-CQI of UE is when being true (true), sends in the CQI resource and carries the PUCCH of ACK information; When ACK information and CQI information clash, and the Simultaneous-AN-and-CQI of UE sends PUCCH in the ACK resource, and abandons CQI information when being false (false); Simultaneous-AN-and-CQI is the configuration parameter of UE, and UE reports network side with the information of its Simultaneous-AN-and-CQI when configuration successful.
In sum, when at UE information collision taking place in the prior art, when receiving the LTE signal that UE sends, the flow process of demodulation PUCCH can be as shown in Figure 1, and this method comprises:
In the prior art, when demodulation PUCCH, at first utilize SR information/ACK information that SR/ACK is activated detection, and determine according to activation result whether UE sends CQI, and there is following defective in this kind mode:
When SR/ACK being activated detection, generally adopt noise statistics and signal statistics to adjudicate, therefore can there be the problem of the empty inspection of SR/ACK or SR/ACK omission to a certain extent, thereby causes the problem of PUCCH false retrieval; As: UE reality sends PUCCH in the CQI resource, and receiving terminal can abandon CQI information when examining SR/ACK is empty, thereby causes receiving terminal demodulation PUCCH on the SR/ACK resource, thereby makes the CQI information of receiving terminal in time correctly to upgrade; And for example, UE reality sends PUCCH in the SR/ACK resource, and receiving terminal is during to the SR/ACK omission, then can make receiving terminal demodulation PUCCH on the CQI resource, thereby obtains wrong CQI information, influences descending scheduling then.
Situation about clashing at SR information and CQI information 1:(1) if receiving terminal to the empty inspection of SR, can cause receiving terminal to give corresponding extra distribution PUSCH (the Physical Uplink Shared Channel of user, Physical Uplink Shared Channel), thus reduced the utilance of effective bandwidth in the system; When also needing to detect ACK information, receiving terminal demodulation ACK information on the SR resource, and UE reality sends ACK information in the CQI resource, thus make receiving terminal obtain wrong ACK information; (2) if receiving terminal to the SR omission and when also needing to detect ACK information, receiving terminal is demodulation ACK information on the CQI resource, and in fact send ACK information in the SR resource, thereby make receiving terminal obtain wrong ACK information.
The situation 2 that clashes at ACK information and CQI information, with the analysis classes of above-mentioned situation 1 seemingly, no matter still ACK omission of the empty inspection of receiving terminal ACK, the capital causes receiving terminal demodulation PUCCH mistake, therefore, when adopting prior art at UE information collision to take place, the accuracy of PUCCH being carried out demodulation is lower.
